In a previous study, we constructed a male reference Korean phantom; HDRK-Man (High-Definition Reference Korean-Man), to represent Korean adult males for radiation protection purposes. In the present study, a female phantom; HDRK-Woman (High-Definition Reference Korean-Woman), was constructed to represent Korean adult females. High-resolution color photographic images obtained by serial sectioning of a 26 year-old Korean adult female cadaver were utilized. The body height and weight, the skeletal mass, and the dimensions of the individual organs and tissues were adjusted to the reference Korean data. The phantom was then compared with the International Commission on Radiological Protection (ICRP) female reference phantom in terms of calculated organ doses and organ-depth distributions. Additionally, the effective doses were calculated using both the HDRK-Man and HDRK-Woman phantoms, and the values were compared with those of the ICRP reference phantoms.

The present study was designed to identify the association between work hours and obesity in Korean adult manual and nonmanual workers, and to determine whether there is a gender difference in this association. The study was conducted using Korean National Health and Nutrition Examination Survey data collected between 2007 and 2010. Individuals aged below 25 or over 64 years, pregnant women, part-time workers, soldiers, housewives and students were excluded. The total number of individuals included in the analysis was 8,889 (5,241 male and 3,648 female subjects). The outcome variable was obesity, defined as body mass index ≥25 kg/m(2). Variables considered in the model were age, education, income, marital status, alcohol drinking, smoking, daily energy intake, physical activity, sleep hours per day, the type of job, work hours, and work schedule. Work hours were categorized as 60 hours per week. In the multiple SURVEYLOGISTIC regression analyses, the adjusted odds ratio of obesity for long work hours (>60 hours per week) in male manual workers was 1.647 (95% confidence interval 1.262-2.151). Long work hours did not significantly increase the odds ratio for obesity in male nonmanual workers and female manual and nonmanual workers. More than 60 work hours per week increased the risk of obesity in Korean male manual workers. This result might be helpful in preventing obesity in Korean adult workers, especially male manual workers.

The purpose of the study was to develop a situation-specific theory for explaining health-related quality of life (QOL) among older South Korean adults with type 2 diabetes. To develop a situation-specific theory, three sources were considered: (a) the conceptual model of health promotion and QOL for people with chronic and disabling conditions (an existing theory related to the QOL in patients with chronic diseases); (b) a literature review using multiple databases including Cumulative Index for Nursing and Allied Health Literature (CINAHL), PubMed, PsycINFO, and two Korean databases; and (c) findings from our structural equation modeling study on health-related QOL in older South Korean adults with type 2 diabetes. The proposed situation-specific theory is constructed with six major concepts including barriers, resources, perceptual factors, psychosocial factors, health-promoting behaviors, and health-related QOL. The theory also provides the interrelationships among concepts. Health care providers and nurses could incorporate the proposed situation-specific theory into development of diabetes education programs for improving health-related QOL in older South Korean adults with type 2 diabetes.

Full Text Available BackgroundCystatin C has been known to be associated not only with early renal impairment but also with the incidence of diabetic conditions (prediabetes plus diabetes. However, it is not clear whether cystatin C levels are associated with the prevalence of diabetic conditions in Asian populations. We evaluated this association using glycosylated hemoglobin (HbA1c levels as the definition of diabetes in Korean adults.MethodsWe analyzed data from 1,559 Korean adults (937 men and 622 women with available serum cystatin C and HbA1c values.ResultsThe serum cystatin C levels in subjects with prediabetes and diabetes were significantly increased (0.91±0.14 mg/L in prediabetes and 0.91±0.17 mg/L in diabetes vs. 0.88±0.13 mg/L in patients with normal glucose levels, P=0.001. At increasing cystatin C levels, the prevalence of subjects with prediabetes (30.2% vs. 14.6%, P<0.001 and those with diabetes (10.6% vs. 8.0%, P<0.001 significantly increased in the group with the highest cystatin C levels. The group with the highest cystatin C levels had a significantly increased odds ratio (OR for the presence of diabetic conditions compared to the group with the lowest values in total subjects (OR, 2.35; 95% confidence interval [CI], 1.54 to 3.58; P<0.001 and in women (OR, 4.13; 95% CI, 1.97 to 8.65; P<0.001, though there was no significant increase after adjusting for multiple variables.ConclusionsHigher levels of serum cystatin C are associated with an increased prevalence of diabetic conditions in Korean adults. Our findings may extend the positive association of cystatin C with diabetes incidence to an Asian population.

Dietary patterns are critical in the prevention of chronic disease. The relationship between specific dietary patterns and obesity has not been evaluated in a Korean adult population. This study examined whether specific dietary patterns are associated with obesity using survey data of the largest, nationally representative, general Korean population. The cross-sectional study was comprised of 10,089 Korean adults (19 years or older) who participated in the second and third Korean National Health and Nutrition Examination Surveys conducted in 2001 and 2005, respectively. Dietary data were assessed by 24-hour recall method. Obesity was defined as body mass index (calculated as kg/m(2)) ≥25, which is the cutoff point for adults in the Asian and Pacific regions. Four dietary patterns were derived using factor analysis (white rice and kimchi pattern; high-fat, sweets, and coffee pattern; meat and alcohol pattern; and grains, vegetables, and fish pattern). Each dietary pattern explained 8.6%, 6.7%, 5.7%, and 5.7% of the variation in food intake, respectively. The white rice and kimchi pattern (P for trend=0.0039) and the high-fat, sweets, and coffee pattern (P for trend=0.0054) were positively associated with obesity after adjustments for age, sex, energy intake, alcohol intake, smoking status, physical activity, and chronic diseases. No significant association was found among the meat and alcohol pattern; the grains, vegetables, and fish pattern; and obesity. Specific dietary patterns, which include the white rice and kimchi and high-fat, sweets, and coffee patterns, may be independently associated with obesity in Korean adults.

Acne is a chronic inflammatory disease of the pilocebaceous unit that presents with various spectrum and severity. Genetic backgrounds and environmental factors are also considered to be relevant, but few studies have focused on Korean patients. A cross-sectional epidemiologic study on family history of Korean acne patients was performed to analyze family history of acne, and to compare the severity and characteristics of acne in association with family history. A total of 221 patients were enrolled, 98 male (44.3%) and 123 female (55.7%). Patients were grouped as patients with (A+) or without (A-) family history of acne. In a second analysis, patients with any experience of acne treatment were evaluated. Severity of acne was measured with Burton's grading system and Korean Acne Grading System (KAGS). Female patients had a higher tendency to have family history than males (P = 0.002). Group A+ had statistically significant earlier onset of acne (P = 0.002). In inexperienced patients, patients with family history showed a relatively earlier onset (P = 0.084). This study confirmed the role of heredity in acne. Family history of acne is associated with earlier onset of the disease, and more non-inflammatory lesions. © 2014 Japanese Dermatological Association.

2013-01-01

This study simultaneously addresses the issues of the scarcity of information about pediatric patient color preferences, conflicting findings about the impact of culture on color preferences, and limitations of previous research instruments. Effects of culture and gender on color preferences were investigated using American and Korean pediatric patients. Much of the existing research in environmental design has focused on environments for healthy children and adults, but those findings cannot be confidently applied to environments for pediatric patients. In previous studies, the impact of culture on color preferences has been suggested, though the effects appear to vary. Moreover, the results of previous studies were typically based on perceptions of small color chips, which are different from seeing a color on wall surfaces. Previous studies also failed to control for confounding variables such as color attributes and light sources. Instead of using color chips, this study used physical model simulation to investigate environmental color preferences in real contexts. Cultural difference was found in white. Other than white, no significant cultural difference was found. Gender differences were found across both of the groups. Korean pediatric patients showed significantly higher preference scores for white than Americans did. Other than white, both groups reported blue and green as their most preferred colors; white was the least preferred. Both groups reported similar gender effects. Overall, male patients reported significantly lower preference scores for red and purple than female patients did. These results can help healthcare providers and professionals better understand appropriate colors for pediatric populations.

We aimed to explore the associations of dietary patterns with blood lipid profiles and obesity in adults with type 2 diabetes. The data were obtained from the Forth Korean National Health and Nutrition Examination Survey, 2007-2008. Adults 30 yr or older, from which had both biochemical and dietary data were obtained. Among them, 680 subjects were defined as having diabetes based on criteria of fasting glucose ≥ 126 mg/dL, anti-diabetic treatment, or previously diagnosed diabetes. Dietary data from a 24-hr recall were used to derive dietary patterns by factor analysis. Four dietary patterns by factor analysis were identified: 'Bread & Meat & Alcohol', 'Noodles & Seafood', 'Rice & Vegetables', and 'Korean Healthy' patterns. Serum cholesterol levels in the highest quartile of the 'Bread & Meat & Alcohol' pattern were significantly higher compared with those in the lowest quartile. In addition, total cholesterol and triglyceride levels in the highest quartile of the 'Korean Healthy' pattern were significantly lower after adjusting for potential confounders. Dietary patterns of adults with diabetes were found to be associated with blood lipid profiles. 'Korean Healthy' pattern including whole grains, legumes, vegetables, and fruits could thus improve lipid profiles among those with type 2 diabetes.

Called dotage in Korea, dementia is primarily characterized by cognitive impairments. Secondary manifestations include mental-emotional problems, including depression. This study was designed to examine the effects of an integrated dementia intervention for Korean older adults. The intervention is composed of cognitive stimulation training, exercise, music, art, and horticultural therapy. Participants included 38 older adults with mild dementia. Twenty were assigned to the experimental group and 18 to the control group. Participants in the experimental group attended 18 program sessions. Significant differences were found postintervention between the two groups in measures of cognitive function, depression levels, and mental-emotional health. The findings indicate that this integrated dementia intervention can be applied to help older adults with mild dementia. Copyright 2010, SLACK Incorporated.

With population aging now a global phenomenon, the health of older adults is becoming an increasingly important issue. Because the Korean population is aging at an unprecedented rate, preparing for public health problems associated with old age is particularly salient in this country. As the physical and mental health of older adults is related to their social relationships, investigating the social networks of older adults and their relationship to health status is important for establishing public health policies. The aims of this study were to identify social network types among older adults in South Korea and to examine the relationship of these social network types with self-rated health and depression. Data from the Korean Social Life, Health, and Aging Project were analyzed. Model-based clustering using finite normal mixture modeling was conducted to identify the social network types based on ten criterion variables of social relationships and activities: marital status, number of children, number of close relatives, number of friends, frequency of attendance at religious services, attendance at organized group meetings, in-degree centrality, out-degree centrality, closeness centrality, and betweenness centrality. Multivariate regression analysis was conducted to examine associations between the identified social network types and self-rated health and depression. The model-based clustering analysis revealed that social networks clustered into five types: diverse, family, congregant, congregant-restricted, and restricted. Diverse or family social network types were significantly associated with more favorable subjective mental health, whereas the restricted network type was significantly associated with poorer ratings of mental and physical health. In addition, our analysis identified unique social network types related to religious activities. In summary, we developed a comprehensive social network typology for older Korean adults.

The purpose of this review is to explore cultural influences on the experiences of Korean, Korean American, and Caucasian American family caregivers caring for frail older adults in terms of the selection of a primary caregiver, caregiving motivation, support/help-seeking, and negative emotional responses(depression and burden). Seven electronic databases were searched to retrieve studies from 1966 to 2005. Thirty-two studies were identified. This review supported cultural influences on the selection of primary caregiver, caregiving motivation, and support/help-seeking among the three caregiver groups. In Korean caregivers, the major primary caregivers were daughters-in-law while among Korean American and Caucasian American caregivers, the major primary caregivers were daughters or spouses. As a major caregiving motivation, Caucasian American caregivers reported filial affection while Korean caregivers and Korean American caregivers reported filial obligation. Korean caregivers reported higher extended family support, while Caucasian American caregivers reported higher utilization of formal support. Korean caregivers showed the highest levels of depression followed by Korean American caregivers and Caucasian American caregivers. In order to develop culturally appropriate interventions and policies, more research is needed to further explain these differences among the three groups, especially regarding support/help-seeking and negative emotional responses.

To establish upper limit of normal splenic length of Korean adults on ultrasonography and to determice the degree of interobserver and intraobserver variation. Ultrasonographic scans were performed to measure the maximum length of spleen in 105 of 150 adults selected by convenience sampling. Remained 45 cases with any conditions that could alter splenic size were excluded from this study. The maximum length of spleen was measured and correlated with body surface area, patient height, weight, age and sex. In 31 of the 105 adults we evaluated the interobserver and intraobserver variations in sonographic measurements of splenic length obtained by three radiologists in blind fashion. The mean splenic length in 105 adults was 8.56cm ({+-} 0.95). The splenic length positively correlated with body surface area, patient height and weight (P <0.001), and negatively correlated with patient age (P < 0.01). Male spleen (8.87 cm {+-} 1.07) was longer than female spleen (8.35 cm {+-} 0.81) (P < 0.05). The following guidelines are proposed for the upper limit of normal splenic length at different groups of body surface area: no longer than 10 cm at 1.20{approx}1.59 m{sup 2}, 11 cm at1.60{approx}1.79 m{sup 2}, and 12 cm at 1.80{approx}1.99 m{sup 2}. The mean interobserver variation between any two radiologists ranged from 0.32 cm ({+-} 0.29) to 0.39 cm ({+-} 0.33) and interobserver variations were within 1 cm in 96%. The mean intraobserver variations were within 0.5 cm in 91%. The splenic length closely correlated with body surface area, patient height, weight and age. Particularly the upper limit of normal splenic length changed according to body surface area. Interobserver variation about 1 cm and intraobserver variation about 0.5 cm should be considered in the measurement of the splenic length on ultrasonography

Fall is a common cause of disability and death in old adults, and much research has been focused on identifying risk factors and developing preventive measures. Yet the majority of preceding research has been focused on physical performance. This study aims to evaluate the association between fall and depressive symptoms in community-dwelling elderly. Cross-sectional data of 431 men and 546 women was collected from old Korean adults living in Seongnam, Korea. Geriatric fall assessment was conducted by self-report questionnaires. Depressive symptoms were assessed by the Center for Epidemiologic Studies Depression Scale. Results indicated that depressive symptoms were associated with both fall and fear of falling in old adults. A clear gender difference was newly discovered, as depression played a stronger role in women. These results imply that clinicians should consider the negative affect of geriatric patients when assessing fall risk. Also, measures against depression might be effective in reducing falls.

Gender Differences in Hypertension Control Among Older Korean Adults: Korean Social Life, Health, and Aging Project

2015-01-01

Full Text Available Objectives: Controlling blood pressure is a key step in reducing cardiovascular mortality in older adults. Gender differences in patients’ attitudes after disease diagnosis and their management of the disease have been identified. However, it is unclear whether gender differences exist in hypertension management among older adults. We hypothesized that gender differences would exist among factors associated with hypertension diagnosis and control among community-dwelling, older adults. Methods: This cross-sectional study analyzed data from 653 Koreans aged ≥60 years who participated in the Korean Social Life, Health, and Aging Project. Multiple logistic regression was used to compare several variables between undiagnosed and diagnosed hypertension, and between uncontrolled and controlled hypertension. Results: Diabetes was more prevalent in men and women who had uncontrolled hypertension than those with controlled hypertension or undiagnosed hypertension. High body mass index was significantly associated with uncontrolled hypertension only in men. Multiple logistic regression analysis indicated that in women, awareness of one’s blood pressure level (odds ratio [OR], 2.86; p=0.003 and the number of blood pressure checkups over the previous year (OR, 1.06; p=0.011 might influence the likelihood of being diagnosed with hypertension. More highly educated women were more likely to have controlled hypertension than non-educated women (OR, 5.23; p=0.013. Conclusions: This study suggests that gender differences exist among factors associated with hypertension diagnosis and control in the study population of community-dwelling, older adults. Education-based health promotion strategies for hypertension control might be more effective in elderly women than in elderly men. Gender-specific approaches may be required to effectively control hypertension among older adults.

The present study explored the relationships between fried food consumption and metabolic risk factors and hypertension in Korean adults. The study was based on the fifth Korean National Health and Nutrition Examination Survey between 2010 and 2011. A total of 9221 Korean adults aged ≥19 years were studied. Fried food consumption was assessed using a validated FFQ. Metabolic risk factors such as waist circumference, fasting plasma glucose (FPG), TAG, HDL-cholesterol and systolic and diastolic blood pressure (SBP and DBP) were measured. Hypertension was defined as SBP≥140 mmHg, DBP≥90 mmHg or current use of antihypertensive medication. Adjusted OR for elevated blood pressure significantly increased in men (OR 1·62; 95% CI 1·11, 2·37; P(trend)=0·0447) and women (OR 2·20; 95% CI 1·21, 4·00; P(trend)=0·0403) with a greater than twice a week consumption of fried food compared with those who rarely consumed fried food. However, fried food consumption was not associated with other metabolic risk factors (abdominal obesity, high FPG, hypertriacylglycerolaemia, low HDL-cholesterol and the metabolic syndrome). The adjusted OR for hypertension increased by 2·4-fold in women (OR 2·37; 95% CI 1·19, 4·72; P(trend)=0·0272) with a greater than twice a week fried food consumption compared with those who rarely consumed it. No significant association was found between fried food consumption and hypertension in men. This study suggests that frequent fried food consumption is associated with hypertension in Korean women. Further studies are needed to investigate the effect of different types of fried foods on hypertension.

The purpose of this study was to identify the factors influencing life satisfaction of Korean older adults living with family. Participants included 267 adults age 65 and older who met eligibility criteria. Analyses showed that the prediction model of the life satisfaction of older adults who are living with their family was significant (F=24.429, ppocket money (beta=0.060), and age (beta=0.040). It is possible that older adults' life satisfaction increases when they are provided with nursing interventions and are able to effectively manage their health. Nursing interventions must strive to improve their self-esteem and address their depression.

The objective of this study was to investigate major dietary patterns among older Korean adults through cluster analysis and to determine an association between dietary patterns and cognitive function. This is a cross-sectional study. The data from the Korean Multi-Rural Communities Cohort Study was used. Participants included 765 participants aged 60 years and over. A quantitative food frequency questionnaire with 106 items was used to investigate dietary intake. The Korean version of the MMSE-KC (Mini-Mental Status Examination-Korean version) was used to assess cognitive function. Two major dietary patterns were identified using K-means cluster analysis. The "MFDF" dietary pattern indicated high consumption of Multigrain rice, Fish, Dairy products, Fruits and fruit juices, while the "WNC" dietary pattern referred to higher intakes of White rice, Noodles, and Coffee. Means of the total MMSE-KC and orientation score of the participants in the MFDF dietary pattern were higher than those of the WNC dietary pattern. Compared with the WNC dietary pattern, the MFDF dietary pattern showed a lower risk of cognitive impairment after adjusting for covariates (OR 0.64, 95% CI 0.44-0.94). The MFDF dietary pattern, with high consumption of multigrain rice, fish, dairy products, and fruits may be related to better cognition among Korean older adults.

Water is essential for the proper functioning of the body. Even though a recommendation exists for adequate water intake for Koreans, studies identifying actual water intake from all beverages and foods consumed daily in the Korean population are limited. Thus, we estimated total water intake from both beverages and foods and its association with energy intake and eating behaviors in Korean adults. We used a nationally representative sample of 25,122 Korean adults aged ≥19 years, from the Korean National Health and Nutrition Examination Survey 2008–2012. We performed multiple regression analyses, adjusting for sociodemographic and health-related variables to investigate the contribution of overall energy and dietary intakes and eating behaviors to total water intake. The mean total water intake excluding plain water was 1071 g (398 g from beverages and 673 g from foods) and the estimated plain water intake was 1.3 L. Among Korean adults, 82% consumed beverages (excluding plain water) and these beverages contributed to 10% of daily energy intake and 32% of total water intake from beverages and foods. For every 100 kcal/day in energy intake, water intake consumed through beverages and foods increased by 18 g and 31 g, respectively. Water intake from beverages and foods was positively associated with energy from fat and dietary calcium, but inversely associated with energy density and energy from carbohydrates. When there was a 5% increase in energy intake from snacks and eating outside the home, there was an increase in water intake from beverages of 13 g and 2 g, respectively. Increased daily energy intake, the number of eating episodes, and energy intake from snacks and eating outside the home predicted higher water intake from beverages and foods. Our results provide evidence suggesting that various factors, including sociodemographic status, dietary intakes, and eating behaviors, could be important contributors to the water intake of Korean adults.

Dyslipidemia, hypertension, and diabetes are well-established risk factors for cardiovascular disease (CVD). This study investigated the prevalence and management status of these factors for dyslipidemia among Korean adults aged 30 years old and older. The prevalence and management status of dyslipidemia, hypertension, and diabetes were analyzed among 12229 subjects (≥30 years) participating in the Korea National Health and Nutrition Survey 2010-2012. Dyslipidemia was defined according to treatment criteria rather than diagnostic criteria in Korea. Therefore, hyper-low-density lipoprotein (LDL) cholesterolemia was defined if LDL cholesterol levels exceeded the appropriate risk-based threshold established by the National Cholesterol Education Program Adult Treatment Panel III. The age-standardized prevalence was highest for dyslipidemia (39.6%), followed by hypertension (32.8%) and diabetes (9.8%). The lowest patient awareness was found for dyslipidemia (27.9%). The treatment rate was 66.5% for diabetes and 57.3% for hypertension, but only 15.7% for dyslipidemia. The control rate among those undergoing treatment was highest for hypertension (64.2%), followed by dyslipidemia (59.2%) and diabetes (22.1%). The higher the risk levels of CVD were, the lower the control rate of dyslipidemia. While the prevalence of dyslipidemia was higher than hypertension and diabetes, awareness and treatment rates thereof were lower. Higher CVD-risk categories showed lower control rates of dyslipidemia. In order to improve awareness and control rates of dyslipidemia, diagnostic criteria should be reconciled with treatment targets based on cardiovascular risk in Korean populations.

Following the previously developed Korean tomographic phantom, KORMAN, two additional whole-body tomographic phantoms of Korean adult males were developed from magnetic resonance (MR) and computed tomography (CT) images, respectively. Two healthy male volunteers, whose body dimensions were fairly representative of the average Korean adult male, were recruited and scanned for phantom development. Contiguous whole body MR images were obtained from one subject exclusive of the arms, while whole-body CT images were acquired from the second individual. A total of 29 organs and tissues and 19 skeletal sites were segmented via image manipulation techniques such as gray-level thresholding, region growing, and manual drawing, in which each of segmented image slice was subsequently reviewed by an experienced radiologist for anatomical accuracy. The resulting phantoms, the MR-based KTMAN-1 (Korean Typical MAN-1) and the CT-based KTMAN-2 (Korean Typical MAN-2), consist of 300x150x344 voxels with a voxel resolution of 2x2x5 mm 3 for both phantoms. Masses of segmented organs and tissues were calculated as the product of a nominal reference density, the prevoxel volume, and the cumulative number of voxels defining each organs or tissue. These organs masses were then compared with those of both the Asian and the ICRP reference adult male. Organ masses within both KTMAN-1 and KTMAN-2 showed differences within 40% of Asian and ICRP reference values, with the exception of the skin, gall bladder, and pancreas which displayed larger differences. The resulting three-dimensional binary file was ported to the Monte Carlo code MCNPX2.4 to calculate organ doses following external irradiation for illustrative purposes. Colon, lung, liver, and stomach absorbed doses, as well as the effective dose, for idealized photon irradiation geometries (anterior-posterior and right lateral) were determined, and then compared with data from two other tomographic phantoms (Asian and Caucasian), and

Full Text Available The effectiveness of the 2011-2012 seasonal influenza vaccine was evaluated in adult Korean populations with regard to how well it could prevent laboratory-confirmed influenza and influenza-related complications.A retrospective case-control and retrospective cohort study was conducted among patients who visited four selected hospitals from September 2011 to May 2012. The analysis included 1,130 laboratory-confirmed influenza patients. For each influenza case, one control patient was chosen at a ratio of 1:1. A control was defined as an age group-matched patient who visited the same hospital with influenza-like illness within 48 hours of symptom onset but for whom laboratory tests were negative for influenza. Age group and visit date were matched between the cases and controls. Vaccine effectiveness (VE was defined as [100 × (1-odds ratio for influenza in vaccinated versus non-vaccinated persons]. The patients with laboratory-confirmed influenza were followed for at least one month through reviewing the medical records and conducting a telephone interview.The VE of the 2011-2012 seasonal influenza vaccine was 3.8% [95% confidence interval (CI, -16.5% to 20.6%] for preventing laboratory-confirmed influenza, -16.1% (95% CI, -48.3 to 9.1 for influenza A and 26.2% (95% CI, -2.6 to 46.2 for influenza B. The age-specific adjusted VE was 0.3% (95% CI, -29.4 to 23.1 among participants aged 19 to 49 years, 11.9% (95% CI, -34.3 to 42.2 among those aged 50 to 64 years and -3.9% (-60.1 to 32.5 among those aged ≥65 years. The adjusted VE for preventing any influenza-related complications was -10.7% (95% CI, -41.1% to 42.2%.The 2011-2012 seasonal influenza vaccine was not effective in preventing laboratory-confirmed influenza or influenza-related complications in adult Korean populations.

To describe the longitudinal characteristics of unintentional fall accidents using a representative population-based sample of Korean adults. We examined data from the Korean Community Health Survey from 2008 to 2013. Univariate analysis and multivariable logistic regression were used to identify the characteristics of fall accidents in adults. Between 2008 and 2013, the incidence rate of fall accidents requiring medical treatment increased from 1,248 to 3,423 per 100,000 people (pfall accidents decreased from 38.12% to 23.16% (pfall accidents than males (pfall accidents was slippery floors (33.7% in 2011 and 36.3% in 2013). Between 2008 and 2010, variables associated with higher fall accident risk included specific months (August and September), old age, female gender, current drinker, current smoker, diabetes, osteoarthritis, osteoporosis, and depression. A high level of education and living with a partner were negatively associated with fall accident risk. In 2013, people experiencing more than 1 fall accident felt more fear of falling than those having no fall accidents (odds ratio [OR] for 1 fall, 2.12; 95% confidence interval [CI], 2.04-2.12; OR for more than 2 falls, 2.97; 95% CI, 2.83-3.10). The occurrence of fall accidents has consistently increased in Korea from 2008 to 2013. Future intervention studies are needed to reduce the increasing incidence rates of fall accidents in community dwelling adults.

1. Radiological evaluation of lung volumes was carried out thirty Korean males patients with silicosis, and following results were obtained. 2. The mean radiological lung volume among those patients was 7,587 ml. 3. When compared with the group of normal Korean male adults ranging from 31 to 55 years of age, the mean lung volume was increased by 2,346 ml. 4. The lung volume of these patients was even slightly larger than that of the group of Korean athletes of all ages. 5. On the other hand, the vital capacity in patients with silicosis was markedly diminished, the mean vital capacity being 2,909 ml. 6. The patients with silicosis also revealed emphysematous changes in the lung as well as increased residual volumes. The vital capacity was smallest in the latest stage.

Full Text Available The objective of this study was to investigate major dietary patterns among older Korean adults through cluster analysis and to determine an association between dietary patterns and cognitive function. This is a cross-sectional study. The data from the Korean Multi-Rural Communities Cohort Study was used. Participants included 765 participants aged 60 years and over. A quantitative food frequency questionnaire with 106 items was used to investigate dietary intake. The Korean version of the MMSE-KC (Mini-Mental Status Examination–Korean version was used to assess cognitive function. Two major dietary patterns were identified using K-means cluster analysis. The “MFDF” dietary pattern indicated high consumption of Multigrain rice, Fish, Dairy products, Fruits and fruit juices, while the “WNC” dietary pattern referred to higher intakes of White rice, Noodles, and Coffee. Means of the total MMSE-KC and orientation score of the participants in the MFDF dietary pattern were higher than those of the WNC dietary pattern. Compared with the WNC dietary pattern, the MFDF dietary pattern showed a lower risk of cognitive impairment after adjusting for covariates (OR 0.64, 95% CI 0.44–0.94. The MFDF dietary pattern, with high consumption of multigrain rice, fish, dairy products, and fruits may be related to better cognition among Korean older adults.

A Korean voxel model, named 'High-Definition Reference Korean-Man (HDRK-Man)', was constructed using high-resolution color photographic images that were obtained by serially sectioning the cadaver of a 33-year-old Korean adult male. The body height and weight, the skeletal mass and the dimensions of the individual organs and tissues were adjusted to the reference Korean data. The resulting model was then implemented into a Monte Carlo particle transport code, MCNPX, to calculate the dose conversion coefficients for the internal organs and tissues. The calculated values, overall, were reasonable in comparison with the values from other adult voxel models. HDRK-Man showed higher dose conversion coefficients than other models, due to the facts that HDRK-Man has a smaller torso and that the arms of HDRK-Man are shifted backward. The developed model is believed to adequately represent average Korean radiation workers and thus can be used for more accurate calculation of dose conversion coefficients for Korean radiation workers in the future

In this study, we analysed sensitization rates to commonly consumed foods in Korean adults suspected of having food allergy. One hundred and thirty four subjects underwent a skin prick test (SPT) with 55 food allergens, of which 13 were made by our laboratory and the rest were commercially purchased. Of the 134 patients, 73 (54.5%) were sensitized to one or more food allergens. Sensitization to chrysalis was detected most frequently, at a rate of 25.4%. Sensitization rates to other food allergens were as follows: maize grain (13.4%), shrimp (11.9%), almond (11.1%), wheat flour (8.2%), lobster (8.2%), buckwheat (8.2%), mackerel (5.2%), pollack (5.2%), halibut (4.5%), peanut (4.5%), anchovy (4.4%), squid (3.7%), saury (3.0%), common eel (3.0%), yellow corvina (3.0%), hairtail (2.2%), octopus (2.2%), and others. In addition to well-known food allergens, sensitivity to mackerel, chrysalis, pollack, and halibut, which are popular foods in Korea, was observed at high rates in Korean adults. We suggest that the SPT panel for food allergy in Korea should include these allergens.

The aim of this study was to identify the perceived attitudes of Korean adults towards human dignity in order to determine the relationship of human dignity to its social and cultural background. The Q methodology research technique was used to explore perceived attitude typology on the basis of the respondents' ranking order for different statements. A convenience sampling method was used to select 40 Korean adults who were interested in human dignity to create statements. From the questionnaires, in-depth interviews, and a literature review, a total of 158 statements was obtained. The final 34 Q samples were selected from a review by two nursing professors and a Q methodology expert. Moreover, 38 respondents participated as P samples by sorting 34 Q statements on a nine-point normal distribution scale. The data were analyzed by using the QUANL software package. The following four types of attitudes about human dignity were identified in Korea: a happiness-oriented-self-pursuit type, relationship-oriented-self-recognition type, reflection-oriented-self-unification type, and discrimination-oriented-self-maintenance type. The results indicate that approaches to developing human dignity education need to take this typology into account and the characteristics of the participants who fall into each category. These results provide general guidelines to understand Korean values for professional practice in various healthcare settings. © 2011 The Authors.

The objective of this study was to examine the perceived health status, family support and life satisfaction of older Korean adults and the relationships among them. This study was designed to be a descriptive correlation study using questionnaire. Subjects were 246 older people who were over 65 years of age in Seoul and Daegu metropolitan city, Korea. Measures were the Cornell Medical Index-Simple Korean Form to measure the perceived health status, the Family Support Instrument to measure the family support and the Standard Life Satisfaction Instrument for Korean people to measure the life satisfaction. Perceived health state was worse as average 3.3, family support was good as average 3.4 and life satisfaction was low as average 3.1. There were statistically significant positive correlations among perceived health state, family support and life satisfaction and between family support and life satisfaction. The predictors of life satisfaction in elderly were family support, age, monthly allowance and perceived health state. These factors explained 37.5% of the total variance. The major influencing factor was family support. This cross-sectional study provides preliminary evidence that to develop nursing strategy to increase family support of older Korean adults is needed. © 2012 Blackwell Publishing Asia Pty Ltd.

2015-12-01

This study investigated the relationship between family composition and the prevalence of metabolic syndrome by gender in Korean adults aged 45 years and older. The sample consisted of 11,291 participants in the Korea National Health and Nutrition Examination Survey from 2010 to 2012. We used complex sample analyses, including strata, cluster, and sample weighting, to allow generalization to the Korean population. Complex samples crosstabs and chi-square tests were conducted to compare the percentage of sociodemographic characteristics to the prevalence of metabolic syndrome and its components by gender and family composition. Next, a complex sample logistic regression was performed to examine the association between family composition and the prevalence of metabolic syndrome by gender. The percentage of adults living alone was 5.6% for men and 13.9% for women. Slightly more women (14.0%) than men (10.1%) reported living with three generations. The percentage of metabolic syndrome in Korean adults aged 45 years and older was 53.2% for men and 35.7% for women. For women, we found that living with one or three generations was significantly associated with a higher risk of metabolic syndrome, blood pressure, and triglyceride abnormality after adjusting for age, education, household income, smoking, physical activity, and body mass index, when compared to living alone. No significant relationships were found for men. A national strategy, tailored on gender and family composition, needs to be developed in order to prevent the increase of metabolic syndrome in Korean women over middle age. Copyright © 2015.

2003-01-01

Breathing rate is one of the key factors in evaluating doses due to inhalation of airborne radionuclides. Since the reference values of breathing rate provided by the International Commission on Radiological Protection (ICRP) are based on the physiology of Caucasian, they are not necessarily appropriate for internal dosimetry for Korean. In this study, we assessed breathing rate of Korean by measuring the forced vital capacity (FVC), the forced expiratory volume in second (FEV1) and the minute ventilation(MV). Measurements were made using SP-1 spirometry unit (Schiller AG. 1998) for 1474 adult Koreans whose heights and weights are in the range of one standard deviation from the mean values. The total liters of air breathed for working and resting were evaluated after the ICRP approach. We also considered smoking and ailment in the lungs. The resulting breathing rate appears to be 2.3x10 4 L/day which well agrees with the value given in ICRP 23

Carcinoembryonic Antigen is one of most frequently checked tumor markers in cancer management. We performed statistical analysis with serum CEA data of 2626 persons who received regular health examination and were thought to be free of active disease to determine the cutoff values of serum CEA level in normal Korean adults and to study the factors influencing serum CEA levels in normal subjects. 1) The cutoff values of serum CEA in normal Korean adults in general were 9.28 ng/ml for men, 5.90 ng/ml for women. 2) Serum CEA level was influenced by age, present smoking history, sex, and abnormal findings in chest X ray. 3) Serum CEA level had no correlation with the history of amount of alcohol consumption or obesity. 4) Cutoff values of serum CEA in normal Korean adults were tabulated according to age, sex, and smoking history. Serum CEA level was influenced by age, sex, present smoking history and abnormal findings in chest X ray and cutoff values of serum CEA were tabulated according to age, sex, and smoking history.

In vivo organ mass of the Korean adult, male and female were presented for the purpose of radiation protection. A total of 121 healthy volunteers (66 males and 55 females), whose body dimensions were close to that of average Korean adults, were recruited for this study. Whole-body magnetic resonance (MR) images were obtained, and contours of 15 organs (brain, eye, gall bladder, heart, kidney, liver, lung, pancreas, stomach, spleen, testes, thymus, thyroid, urinary bladder and uterus) and 9 bones (femur, tibia + fibula, humerus, radius + ulna, pelvis, cervical spine, thoracic and lumber spine, skull and clavicle) were segmented for organ volume rendering by anatomists using commercial software. Organ and bone masses were calculated by multiplying the Asian reference densities of the corresponding organs and bones by the measured volumes. The resulting organ and bone masses were compared with those of the International Commission of Radiological Protection (ICRP) and the Asian reference data. Significantly large standard deviation was shown in the moving organs of the respiratory and circulatory systems and in the alimentary and urogenital organs that are variable in volume in a single person. Gall bladder and pancreas showed unique Korean organ masses compared with those of ICRP and the Asian reference adults. Different from anatomical data based on autopsy, the in vivo volume and mass in this study can more exactly describe the organ volume of a living human subject for radiation protection. A larger sample size would be required for obtaining statistically more reliable results. It is also needed to establish the reference organ mass of younger age groups for which it is difficult to recruit volunteers and to immobilise the subjects for long-time MR scanning. At present, the data from this study will contribute to the establishment of a Korean reference database. (authors)

Epidemiological studies have suggested that flavonoids exhibit preventive effects on degenerative diseases. However, lack of sufficient data on flavonoid intake has limited evaluating the proposed effects in populations. Therefore, we aimed to estimate the total and individual flavonoid intakes among Korean adults and determine the major dietary sources of these flavonoids. We constructed a flavonoid database of common Korean foods, based on the food list reported in the 24-h recall of the Korea National Health and Nutrition Examination Survey (KNHANES) 2007-2012, using data from the Korea Functional Food Composition Table, US Department of Agriculture flavonoid database, Phenol-Explorer database and other analytical studies. This database, which covers 49 % of food items and 76 % of food intake, was linked with the 24-h recall data of 33 581 subjects aged ≥19 years in the KNHANES 2007-2012. The mean daily intake of total flavonoids in Korean adults was 318·0 mg/d, from proanthocyanidins (22·3%), flavonols (20·3%), isoflavones (18·1%), flavan-3-ols (16·2%), anthocyanidins (11·6%), flavanones (11·3%) and flavones (0·3%). The major contributing food groups to the flavonoid intake were fruits (54·4%), vegetables (20·5%), legumes and legume products (16·2%) and beverages and alcohols (3·1%), and the major contributing food items were apples (21·9%), mandarins (12·5%), tofu (11·5%), onions (9·6%) and grapes (9·0%). In the regression analysis, the consumption of legumes and legume products, vegetables and fruits predicted total flavonoid intake the most. The findings of this study could facilitate further investigation on the health benefits of flavonoids and provide the basic information for establishing recommended flavonoid intakes for Koreans.

Objective To describe the longitudinal characteristics of unintentional fall accidents using a representative population-based sample of Korean adults. Methods We examined data from the Korean Community Health Survey from 2008 to 2013. Univariate analysis and multivariable logistic regression were used to identify the characteristics of fall accidents in adults. Results Between 2008 and 2013, the incidence rate of fall accidents requiring medical treatment increased from 1,248 to 3,423 per 100,000 people (pfall accidents decreased from 38.12% to 23.16% (pfall accidents than males (pfall accidents was slippery floors (33.7% in 2011 and 36.3% in 2013). Between 2008 and 2010, variables associated with higher fall accident risk included specific months (August and September), old age, female gender, current drinker, current smoker, diabetes, osteoarthritis, osteoporosis, and depression. A high level of education and living with a partner were negatively associated with fall accident risk. In 2013, people experiencing more than 1 fall accident felt more fear of falling than those having no fall accidents (odds ratio [OR] for 1 fall, 2.12; 95% confidence interval [CI], 2.04–2.12; OR for more than 2 falls, 2.97; 95% CI, 2.83–3.10). Conclusion The occurrence of fall accidents has consistently increased in Korea from 2008 to 2013. Future intervention studies are needed to reduce the increasing incidence rates of fall accidents in community dwelling adults. PMID:27606272

Full Text Available OBJECTIVES: To evaluate the association between secondhand smoke exposure (SHSE and mental health problems among Korean adults. METHODS: We analyzed data from the 2011 Korean Community Health Survey. From the total of 229,226 participants aged 19 years or above, we excluded 48,679 current smokers, 36,612 former smokers, 3,036 participants with a history of stroke, 2,264 participants with a history of myocardial infarction, 14,115 participants who experienced at least one day in bed per month due to disability, and 855 participants for whom information regarding SHSE or mental health problems was not available. The final analysis was performed with 22,818 men and 100,847 women. Participants were classified into four groups according to the duration of SHSE: none, <1 hr/d, 1-<3 hr/d, and ≥3 hr/d. The presence of depressive symptoms, diagnosed depression, and high stress were measured by questionnaire. RESULTS: After adjusting for demographic factors, lifestyle, and chronic disease, the odds ratio (OR and 95% confidence interval (CI of depressive symptoms with 1-<3 hr/d and ≥3 hr/d SHSE were 1.44 (95% CI, 1.14 to 1.82 and 1.59 (95% CI, 1.46 to 1.74, respectively. However, SHSE ≥3 hr/d had a higher OR of 1.37 (95% CI, 1.20 to 1.58 for diagnosed depression. SHSE was also associated with high stress (1-<3 hr/d: OR, 1.56; 95% CI, 1.38 to 1.76; ≥3 hr/d: OR, 1.33 95% CI, 1.28 to 1.40. However, the association between SHSE and symptoms of depression and stress did not differ significantly by region. CONCLUSIONS: SHSE may be associated with mental health problems such as depression and stress in Korean adults.

Background The sodium intake of Koreans was higher than that recommended by the World Health Organization. Urinary sodium, which is correlated with sodium intake, can be easily calculated by the Tanaka's equation. This study aimed to evaluate the association between urinary sodium and metabolic syndrome in Korean adults using the 2010–2011 Korean National Health and Nutrition Examination Survey (KNHANES). Methods A total of 5,870 participants from the 2010–2011 KNHANES were included in this study. Twenty-four hour urinary sodium was calculated by the Tanaka's equation using spot urine. Participants were divided into tertiles based on urinary sodium levels. The association between urinary sodium and metabolic syndrome was analyzed using multivariate logistic regression analysis. Results The odds ratios (ORs) and 95% confidence intervals (CIs) of metabolic syndrome for the 2nd and 3rd tertile of urinary sodium levels was 1.51 (1.16–1.97) and 1.56 (1.23–1.97) compared to the lowest tertile of urinary sodium in men. The ORs and 95% CIs of metabolic syndrome in women were 1.20 (0.95–1.51) for the 2nd tertile and 2.16 (1.68–2.78) for the 3rd tertile. These associations remained statistically significant, even after adjusting for multiple covariates such as age, education, regular exercise, smoking, and alcohol consumption. Conclusion These findings indicate that urinary sodium is significantly associated with metabolic syndrome in Korean adults. PMID:28775809

The purpose of the study was to explore and describe the experience of adult Korean children who are caregivers for parents institutionalized with dementia. Participants were fourteen adult children caregivers of elders institutionalized with dementia. Data were collected through in-depth unstructured interviews with individual participants from August to November, 2012. Theoretical sampling was used to the point of theoretical saturation. Data were analyzed using Strauss and Corbin's Grounded Theory Method. From open coding, 67 concepts, 29 sub-categories, and 14 categories were identified. Analysis revealed that the core category of the experience of adult children caring for their parents institutionalized with dementia was 'enduring the role of a prop' consisting of four phases: initial turmoil, exploration, role adjustment, and acclimation. To manage the role of a prop, participants utilized various action/interactional strategies such as overcoming the unfamiliarity, overseeing the nursing home care, and counterbalancing the caring roles. As a result, participants experienced ambivalence towards the existence of parents with dementia, changes in family relationships, altered viewpoint towards nursing homes, and restructuring of life. In-depth understanding of the experience will guide nurses to promote effective interventions in order to better support the Korean family caregivers of parents institutionalized with dementia.

BACKGROUND/OBJECTIVES The commercial foodservice industry in Korea has shown rapid growth recently. This study examined Korean adults' consumption of commercially-prepared meals based on where the food was prepared. SUBJECTS/METHODS Data from a 24-hour dietary recall of the 2001 and 2011 Korea National Health and Nutrition Examination Surveys were analyzed. A total of 10,539 subjects (n = 6,152 in 2001; n = 4,387 in 2011) aged 19-64 years were included for analysis. Commercially-prepared meals were classified into four food source groups based on where the food was prepared: Korean restaurants, Chinese/Western/Japanese restaurants, fast-food restaurants, and retail stores. Subjects' energy intake, including the amount and proportion of calories, was examined for each food source. The analysis was also conducted by gender for age-stratified groups: 19-29, 30-49, and 50-64 years old. RESULTS Korean adults' energy intake from commercially-prepared meals increased in the amount of calories (551 kcal to 635 kcal, P food source of commercially-prepared meals was Korean restaurants in both years. The amount and proportion of calories from retail stores increased from 83 kcal to 143 kcal (P Korean adults consumed about one-fourth of their energy intake from commercially-prepared meals. In particular, males aged 30-49 years and females aged 19-29 years consumed more than one-third of their energy intake from commercially-prepared meals. Korean restaurants played a significant role in Korean adults' energy intake. Retail stores increased influence on Korean adults' energy intake. These results could be useful for developing health promotion policies and programs. PMID:28386389

For patients with ankylosing spondylitis (AS), golimumab has consistent efficacy in controlling disease activity over 5 years but its benefit in preventing radiographic progression was less clear at 4 years. To predict radiographic progression, we analyzed the baseline characteristics of AS patients in a Korean population. Sixty-eight Korean patients with AS participated in the phase 3, multicenter, randomized, placebo-controlled, double-blind trial (GO-RAISE) which has previously been described. Baseline modified stoke AS spine score (mSASSS) and change in mSASSS from baseline (ΔmSASSS) until week 208 were analyzed in the Korean patients enrolled in the GO-RAISE study. Although Korean patients had lower baseline mSASSS compared to non-Korean patients and received active management, radiographic progression was not prevented. Korean patients who did not undergo radiographic progression of spinal lesions of AS were younger and had shorter symptomatic duration, lower Bath AS functional and metrology indices, better chest expansion, and lower baseline mSASSS. The baseline mSASSS and ΔmSASSS were positively correlated in Korean AS patients ( p baseline mSASSS > 10 and less common (13.0%) with baseline mSASSS = 0. In Korean AS patients, radiographic progression of the spine after 4 years was predicted effectively by the initial severity of the spinal lesion(s) in patients treated with golimumab.

Background Although hemorrhoids are one of the most common anal diseases among Koreans, risk factors for hemorrhoids have not been well identified. Methods We analyzed the data from the 4th Korean National Health and Nutrition Examination Survey (KNHANES) between 2007 and 2009. Study subjects were 17,228 participants of KNHANES who were aged 19 years or older. Logistic regression analysis was conducted to evaluate associations between hemorrhoids and probable risk factors. Results Overall prevalence of hemorrhoids among study subjects was 14.4%, being more prevalent among women (15.7%) than among men (13.0%). Obesity and abdominal obesity were associated with a higher risk of hemorrhoids with odds ratio (OR) (95% confidence intervals, 95% CI) of 1.13 (1.01 to 1.26) and 1.16 (1.04 to 1.30), respectively. Both self-reported depression (OR, 1.83; 95% CI, 1.62 to 2.08) and physician diagnosed depression (OR, 1.71; 95% CI, 1.35 to 2.17) were associated with significantly higher risk of hemorrhoids. No regular walking (OR, 1.11; 95% CI, 1.00 to 1.23) and experience of pregnancy (OR, 1.62; 95% CI, 1.17 to 2.25) for women were also associated with higher risk of hemorrhoids. However, educational level, alcohol consumption, physical activities, diabetes mellitus, hypertension, fiber, fat intake, and energy intake were not associated with a risk of hemorrhoids. Low quality of life assessed with EuroQol-5 Dimension and EuroQol-Visual Analogue Scale was significantly associated with hemorrhoids. Conclusion This nationwide cross-sectional study of Korean adults suggests that obesity, abdominal obesity, depression, and past pregnancy may be risk factors for hemorrhoids and hemorrhoids affect quality of life negatively.

2016-10-01

The current study aimed to identify the prevalence and associated factors of erectile dysfunction (ED) among 161 Korean adults 60 and older with coronary artery disease (CAD). ED was diagnosed in 72.2% of patients-the prevalence of which was significantly associated with age, education, employment, monthly income, frequency of sexual intercourse, body mass index, and low-density lipoprotein. Health-related quality of life (HRQoL) was lower in patients with ED than in those without ED (p < 0.001). Hierarchical multiple regression analysis revealed that ED significantly influenced HRQoL in patients with CAD after adjusting for sociodemographic and disease-related characteristic variables (p < 0.001). Interventions and training courses for health care providers should focus on improving caregivers' knowledge and communication skills with patients and spouses regarding sexual health. Furthermore, guidelines to improve HRQoL in patients with CAD should consider incorporating sexual counseling. [Journal of Gerontological Nursing, 42(10), 32-41.].

The aim of this study is to evaluate whether the triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) ratio is associated with periodontal disease in Korean adults. This cross-sectional study included 12,249 individuals (4,941 men and 7,308 women) who took part in the 2012-2014 Korean National Health and Nutrition Examination Survey. We categorized the TG/HDL-C ratio into three groups. Periodontal disease was defined as a community pocket index score ≥3 with at least one affected site. Multiple logistic analyses were used to analyze the association between TG/HDL-C ratio and periodontal disease. In the study population, prevalence of periodontal disease was 31.6% in men and 21% in women. Compared to the lowest tertile group, OR (95% CI) of the highest tertile group for periodontal disease was 1.474 (1.220-1.780) in men and 1.259 (1.041-1.522) in women after adjusting for age, waist circumference, systolic blood pressure, fasting glucose, current smoking, alcohol drinking, physical activity, household income, oral health behavior, and use of anti-dyslipidemia medication. Our study suggests that the TG/HDL-C ratio is associated with periodontal disease in Korean adults. TG/HDL-C ratio is a simple and useful marker to reflect insulin resistance. And periodontal disease is also known to be related with insulin resistance. This study indicates that TG/HDL-C ratio was associated with periodontal disease in Korean adults.

The aim of this study was to assess the metabolic characteristics and risks of stone recurrence in young adult stone patients in Korea. The medical records of 1532 patients presenting with renal or ureteric stones at our stone clinic between 1994 and 2015 were retrospectively reviewed. Patients were grouped according to age (young adult, 18-29 years; intermediate onset, 30-59 years; old age, ≥60 years) at first presentation, and measurements of clinicometabolic characteristics and risks of stone recurrence were compared. Overall, excretion of urinary stone-forming substances was highest in the intermediate onset group, followed by the young adult and old age groups. Importantly, excretion of urinary citrate was lowest in the young adult group. Kaplan-Meier analyses identified a significant difference between the three age groups in terms of stone recurrence (log rank test, p adult stone patients. Younger age (18-29 years) at first stone presentation was a significant risk factor for stone recurrence, and urinary citrate excretion was an independent risk factor affecting recurrence in this group. Metabolic evaluation and potassium citrate therapy should be considered for young adult stone patients to prevent recurrence.

The objectives of this study were to assess the quality of marital life (QML) in patients with spondyloarthropathy (SpA) in Korea and to identify possible gender differences in QML in patients with SpA. This was a case-control study at the outpatient unit of a tertiary care medical centre. Subjects were the patient group, composed of 47 married patients with SpA, and a comparison group composed of 47 healthy married adults with similar demographic characteristics. QML was measured using the Marital Satisfaction Inventory, Revised. As a result, QML was similar for both the male patients and the healthy men. However, the female patients had higher scores on the global distress scale (59.8 +/- 6.3 vs. 53.8 +/- 5.6, P=0.021) and the aggression scale (50.5 +/- 7.9 vs. 44.3 +/- 5.4, P=0.016) than the female comparison group. At the same time, the female patients demonstrated higher scores on the global distress scale (59.8 +/- 6.3 vs. 54.7 +/- 7.2, P=0.035) than the male patients. In conclusion, QML in Korean males with SpA was not greatly different from that of the male comparison group. However, QML in the female patients was characterised by higher global distress and a higher probability of aggression from their partner, but no significant sexual dissatisfaction.

Instant noodles are widely consumed in Asian countries. The Korean population consumed the largest quantity of instant noodles in the world in 2008. However, few studies have investigated the relationship between instant noodles and nutritional status in Koreans. The objective of this study was to examine the association between instant noodle consumption and food and nutrient intake in Korean adults. We used dietary data of 6,440 subjects aged 20 years and older who participated in the Korean National Health and Nutrition Examination Survey III. The average age of the instant noodle consumers (INC) was 36.2 and that of the non-instant noodle consumers (non-INC) was 44.9; men consumed more instant noodles than women (P instant noodles may lead to excessive intake of energy, fats, and sodium but may also cause increased intake of thiamine and riboflavin. Therefore, nutritional education helping adults to choose a balanced meal while consuming instant noodles should be implemented. Additionally, instant noodle manufacturers should consider nutritional aspects when developing new products.

Full Text Available Meat consumption has been shown to be associated with cardiovascular disease (CVD risk in Western societies; however, epidemiological data are limited on the Korean population. Therefore, we examined the associations between unprocessed meat consumption and CVD incidence in Korea. Data were derived from the Ansung-Ansan cohort (2001–2012, including 9370 adults (40–69 years without CVD or cancer at baseline. Total unprocessed meat consumption was estimated as the sum of unprocessed red meat (beef, pork, and organ meat and poultry consumption. In the fully adjusted Cox regression model, the relative risks of CVD across increasing quintiles of total unprocessed meat intake were 1.0 (reference, 0.72 (95% confidence interval (CI: 0.55, 0.95, 0.57 (95% CI: 0.42, 0.78, 0.69 (95% CI: 0.51, 0.95, and 0.69 (95% CI: 0.48, 0.97, but no significant linear trend was detected (p for trend = 0.14. Frequent poultry consumption was significantly associated with a decreased CVD risk; this association showed a dose-response relationship (p for trend = 0.04. This study showed that a moderate intake of total unprocessed meat was inversely associated with CVD risk. A significant inverse association between poultry consumption and incident CVD was observed in Korean adults, requiring further confirmation in other populations.

To investigate the association between self-reported sleep duration and serum vitamin D level in elderly Korean adults. Cross-sectional data analysis. Korean National Health and Nutrition Examination Survey 2010. Noninstitutionalized adults aged 60 to 80 (N = 1,614). The confounding variables were serum 25-hydroxy vitamin D level, age, sex, body mass index, smoking history, alcohol consumption, and self-reported daily sun exposure and sleep duration. Self-reported daily sleep duration was divided into four groups: Q1 (≤4 hours), Q2 (5-6 hours), Q3 (7-8 hours), and Q4 (≥9 hours). Mean serum vitamin D levels of subjects in the Q1, Q2, Q3, and Q4 groups were 44.18, 48.08, 48.83, and 51.78 nmol/L, respectively. On multivariate linear regression analysis, subjects in the Q2 (B = 3.80, 95% confidence interval (CI) = 0.42-7.19), Q3 (B = 4.89, 95% CI = 1.54-8.24), and Q4 (B = 5.18, 95% CI = 0.78-9.58) groups had significantly higher serum vitamin D levels than subjects in the Q1 group. Serum vitamin D level is positively associated with self-reported daily sleep duration in elderly Korean individuals. These results suggest that inadequate sleep duration may be associated with lower vitamin D levels in elderly adults. © 2014, Copyright the Authors Journal compilation © 2014, The American Geriatrics Society.

Ambient air pollution has a negative effect on many diseases, such as cardiovascular and respiratory diseases. Recent studies have reported a relationship between air pollution and renal function, but the results were limited to exposure to particulate matter (PM). This study was to identify associations between various air pollutants and renal function among Korean adults. Nationwide survey data for a total of 24,407 adults were analyzed. We calculated the estimated glomerular filtration rate (eGFR) for each individual to assess their renal function and used this to categorize those with chronic kidney disease (CKD). To evaluate exposure to ambient air pollution, we used the annual mean concentrations of four ambient air pollutants: PM with an aerodynamic diameter ≤ 10 μm (PM 10 ), nitrogen dioxide (NO 2 ), sulfur dioxide (SO 2 ), and carbon monoxide (CO). We identified significant inverse relationships between the air pollutants PM 10 and NO 2 and eGFR in all statistical adjustment models (all p  ambient air pollutants were significantly related to an increased risk of CKD in the unadjusted model ( p   0.05). Exposures to PM 10 and NO 2 were significantly associated with decreases in eGFR levels, but not CKD, in Korean adults.

The triglyceride glucose (TyG) index has been suggested as a simple surrogate marker of insulin resistance. However, there are limited data regarding the association between the TyG index and arterial stiffness in adults. Therefore, we evaluated the relationship between the TyG index and arterial stiffness as measured based on brachial ankle pulse wave velocity (baPWV) in Korean adults. A total of 3587 subjects were enrolled in this study. Anthropometric and cardiovascular risk factors were measured. The TyG index was calculated as ln[fasting triglycerides(mg/dl) × fasting glucose(mg/dl)/2], and the insulin resistance index of homeostasis model assessment (HOMA-IR) was estimated. Arterial stiffness was determined by measuring baPWV. The subjects were stratified into four groups based on the TyG index. There were significant differences in cardiovascular parameters among the groups; the mean baPWV increased significantly with increasing TyG index. According to the logistic regression analysis after adjusting for multiple risk factors, the odds ratio (95% CI) for increased baPWV (> 75th percentile) for the highest and lowest quartiles of the TyG index was 2.92 (1.92-4.44) in men and 1.84 (1.15-2.96) in women, and the odds ratio for increased baPWV for the highest and lowest quartiles of the HOMA-IR was 1.80 (1.17-2.78) in men and 1.46 (1.06-2.47) in women, respectively. The TyG index is more independently associated with increased arterial stiffness than HOMA-IR in Korean adults.

Full Text Available Objective Neurodegeneration with brain iron accumulation (NBIA represents a group of inherited movement disorders characterized by iron accumulation in the basal ganglia. Recent advances have included the identification of new causative genes and highlighted the wide phenotypic variation between and within the specific NBIA subtypes. This study aimed to investigate the current status of NBIA in Korea. Methods We collected genetically confirmed NBIA patients from twelve nationwide referral hospitals and from a review of the literature. We conducted a study to describe the phenotypic and genotypic characteristics of Korean adults with atypical pantothenate kinase-associated neurodegeneration (PKAN. Results Four subtypes of NBIA including PKAN (n = 30, PLA2G6-related neurodegeneration (n = 2, beta-propeller protein-associated neurodegeneration (n = 1, and aceruloplasminemia (n = 1 have been identified in the Korean population. The clinical features of fifteen adults with atypical PKAN included early focal limb dystonia, parkinsonism-predominant feature, oromandibular dystonia, and isolated freezing of gait (FOG. Patients with a higher age of onset tended to present with parkinsonism and FOG. The p.R440P and p.D378G mutations are two major mutations that represent approximately 50% of the mutated alleles. Although there were no specific genotype-phenotype correlations, most patients carrying the p.D378G mutation had a late-onset, atypical form of PKAN. Conclusions We found considerable phenotypic heterogeneity in Korean adults with atypical PKAN. The age of onset may influence the presentation of extrapyramidal symptoms.

Several studies demonstrated that reading nutrition labels was associated with healthier food choices, despite some controversy. This study investigated the association between the use of nutrition labels and metabolic syndrome (MetS) in Korean adults. This cross-sectional study included 7756 individuals who participated in the 2007-2009 Korean National Health and Nutrition Examination Survey (KNHANES). A self-reported questionnaire was used to determine participant's awareness of nutrition labels. Modified Asian criteria based on a harmonizing definition of MetS were adopted. Individuals in the group that read nutrition labels (the Reading Group) were youngest and leanest, but their daily caloric intake fell between that of the group that did not read nutrition labels (the Non-Reading Group) and the group that did not know about them (the Not-Knowing Group). The prevalence of MetS was 16.8% in the Reading Group, 27.2% in the Non-Reading Group, and 47.3% in the Not-Knowing Group. In comparison to participants in the Reading Group, the odds ratios (95% confidence interval) for MetS in the participants in the Non-Reading Group and Not-Knowing Group were 1.85 (1.60-2.14) and 4.44 (3.79-5.20), respectively, when not adjusted. The relationship between the use of nutrition labels and MetS remained statistically significant even after adjusting for covariates such as age, sex and socioeconomic status including household income and education level [1.27 (1.05-1.53) in the Non-Reading Group and 1.34 (1.05-1.70) in the Not-Knowing Group]. Reading nutrition labels appeared to be associated with a lower prevalence of MetS in a nationally representative sample of Korean adults. Copyright © 2012 Elsevier B.V. All rights reserved.

This study aimed to investigate factors affecting sarcopenia in different age groups among Korean adults aged 20 years or older. In this secondary analysis, data were collected from records for 17,968, participants who participated in the Korea National Health and Nutrition Examination Survey during 2008-2011. Data were analyzed using multiple logistic regression to determine the associated factors of sarcopenia by age groups. The prevalence of sarcopenia increased significantly with age. Physical activity, blood pressure, waist circumference, triglycerides, vitamin D level were found to be factors significantly associated with sarcopenia in all age groups. Total energy intake was found to be a factor that is significantly associated with sarcopenia among the adults aged 20-39 years. Fasting glucose, suicidal ideation, perceived health status, mobility problem, pain/discomfort, total energy intake were found to be factors associated with sarcopenia in the adults aged 40-64 years. Sex, residential area, smoking, drinking, fasting glucose, osteoarthritis, fall experience, usual activity problem, protein intake were factors associated with sarcopenia in the adults over 65 years of age. The findings show that sarcopenia in adults and the associated factors were different by age groups. Thus, these factors should be considered in the development of intervention programs for the care and prevention of sarcopenia, and such programs should be modified according to different age groups.

The existing literature suggests that serious engagement in leisure activities leads to happiness, life satisfaction, and successful aging among older adults. This qualitative study was used to examine the benefits of serious involvement in leisure activities among older Korean adults who were members of a sports club. Using an analytic data analysis, we identified three main themes associated with the benefits of serious engagement in leisure activities: 1) the experience of psychological benefits, 2) the creation of social support, and 3) the enhancement of physical health. These themes indicate that, through serious involvement in certain physical activities, participants gain various health benefits, which may contribute to successful aging. PMID:25059979

The South Korean government recently developed a master plan for establishing a national trauma system based on the implementation of regional trauma centers. We aimed to compare outcomes between severely injured patients treated at a recently established South Korean trauma center and matched patients treated in American level-1 trauma centers. Two cohorts were selected from an institutional trauma database at Ajou University Medical Center (AUMC) and the American National Trauma Data Bank. Adult patients with an Injury Severity Score of ≥9 were included. Patients were matched based on covariates that affect mortality, using 1:1 propensity score matching. We compared outcomes between the two datasets and performed survival analyses. We created 1,451 and 2,103 matched pairs for the pre-trauma center and post-trauma center periods, respectively. The in-hospital mortality rate was higher in the institutional trauma database pre-trauma center period compared with the American National Trauma Data Bank (11.6% versus 8.1%, P<.001). However, the mortality rate decreased in the institutional trauma database post-trauma center period and was similar to that in the American National Trauma Data Bank (6.9% versus 6.8%, P=.903). Being treated at Ajou University Medical Center Trauma Center was significantly associated with higher mortality during the pre-trauma center period (OR: 1.842, 95% CI: 1.336-2.540; P<.001), although no significant association was observed during the post-trauma center period (OR: 1.102, 95% CI: 0.827-1.468; P=.509). The mortality rate improved after a trauma center was established in a South Korean hospital and is similar to that from matched cases treated at American level-1 trauma centers. Thus, creating trauma centers and a regional trauma system may improve outcomes in major trauma cases. Copyright © 2018 Elsevier Inc. All rights reserved.

Maximal oxygen uptake is generally accepted as the most valid and reliable index of cardiorespiratory fitness and functional aerobic capacity. The exercise test for measuring maximal oxygen uptake is unsuitable for screening tests in public heath examinations, because of the potential risks of exercise exertion and time demands. We designed this study to determine whether work-related physical activity is a potential predictor of maximal oxygen uptake, and to develop a maximal oxygen uptake equation using a non-exercise regression model for the cardiorespiratory fitness test in Korean adult workers. Study subjects were adult workers of small-sized companies in Korea. Subjects with history of disease such as hypertension, diabetes, asthma and angina were excluded. In total, 217 adult subjects (113 men of 21-55 years old and 104 women of 20-64 years old) were included. Self-report questionnaire survey was conducted on study subjects, and maximal oxygen uptake of each subject was measured with the exercise test. The statistical analysis was carried out to develop an equation for estimating maximal oxygen uptake. The predictors for estimating maximal oxygen uptake included age, gender, body mass index, smoking, leisure-time physical activity and the factors representing work-related physical activity. The work-related physical activity was identified to be a predictor of maximal oxygen uptake. Moreover, the equation showed high validity according to the statistical analysis. The equation for estimating maximal oxygen uptake developed in the present study could be used as a screening test for assessing cardiorespiratory fitness in Korean adult workers.

Usual source of care (USC) is one of the hallmarks of primary care. We aimed to examine the status of having a USC and its patient-related sociodemographic factors among Korean adults. Data were obtained from the 2012 Korea Health Panel survey. Panel participants were selected for the study who were aged 18 years or older and who replied to questionnaire items on having a USC (n = 11,935). Of the participants, 21.5% had a usual place and 13.9% had a usual physician. Reasons for not having a USC were seldom being ill (66.1%), the preference to visit multiple medical institutions (27.9%), and others. The private community clinic was the most common type of usual place (57.0%). In patient-reported attributes of care provided by a usual physician, the percentages of positive responses for comprehensiveness and coordination were 67.2% and 34.5%, respectively. By institution type, primary care clinics showed the lowest percentage (32.8%) of positive responses for coordination. Adjusted odds ratios of having a usual physician were 3.77 (95% confidence interval, CI: 3.75-3.79) for those aged 65 years or older (vs. aged 18-34 years), 1.31 (CI: 1.30-1.31) for females (vs. males), 0.72 (CI: 0.72-0.73) for unmarried people (vs. married), 1.16 (CI: 1.16-1.16) for college graduates or higher (vs. elementary school graduate or less), 0.64 for the fifth quintile (vs. the first quintile) by household income, 1.53 (CI: 1.52-1.54) for Medical Aid (vs. employee health insurance) for type of health insurance, and 4.09 (CI: 4.08-4.10) for presence (vs. absence) of a chronic diseases. The proportion of Korean adults who have a USC is extremely low, the most influential factor of having a USC is having a chronic disease or not, and Korean patients experience much poorer health care coordination than do patients in other industrialized countries. The findings of this study will give insight to researchers and policy makers regarding the potential facilitators of and barriers to

Se exhibited a relatively small range of adequate ingestion level for health. An accurate investigation of Se consumption in Korean population has been rare because the database of food containing selenium is rather small. The table of Se content in food is a basic tool for calculating selenium intake. Since diet is the main source of Se intake, the Se content in various foods and personal dietary practices would be primarily determined to evaluate the nutritional status of Se for a population. To evaluate the Se intake levels of a population, a Se food database should be generated based on data produced by high-precision analytical techniques. In addition, this database should contain the Se contents of foods that are regularly consumed by the studied population. Plant foods contain lower Se levels when compared to animal products. However, grains, potatoes, starches, and legumes have been the main sources of carbohydrates and proteins in traditional Korean diet. Since grains such as rice are a staple food and remain the most consumed foods in Korea, their contribution to dietary Se intake might be considerable. However, no reports on the selenium content from plant foods have been compiled for the Korean population. The goal of this study was to measure the Se content in common consumed plant foods such as grain, potatoes, legumes and their products. The legume rich in protein contained relatively high amount of Se when compared to other plant food type. The raw wheat and wheat product which have been imported from abroad showed higher amount of Se than rice mostly produced in Korea. The acquired Se value is useful to assess the Se intake of Korean adults from plant foods.

[Purpose] To investigate associations between vitamin C intake, physical activity, and osteoporosis among Korean adults aged 50 and over. [Subjects and Methods] This study was based on bone mineral density measurement data from the 2008 to 2011 Korean National Health and Nutritional Examination Survey. The study sample comprised 3,047 subjects. The normal group was defined as T-score ≥ −1.0, and the osteoporosis group as T-score ≤ −2.5. The odds ratios for osteoporosis were assessed by logistic regression of each vitamin C intake quartile. [Results] Compared to the lowest quartile of vitamin C intake, the other quartiles showed a lower likelihood of osteoporosis after adjusting for age and gender. In the multi-variate model, the odds ratio for the likelihood of developing osteoporosis in the non-physical activity group significantly decreased to 0.66, 0.57, and 0.46 (p for trend = 0.0046). However, there was no significant decrease (0.98, 1.00, and 0.97) in the physical activity group. [Conclusion] Higher vitamin C intake levels were associated with a lower risk of osteoporosis in Korean adults aged over 50 with low levels of physical activity. However, no association was seen between vitamin C intake and osteoporosis risk in those with high physical activity levels. PMID:27134348

Full Text Available Diet plays a crucial role in cognitive function. Few studies have examined the relationship between dietary patterns and cognitive functions of older adults in the Korean population. This study aimed to identify the effect of dietary patterns on the risk of mild cognitive impairment. A total of 239 participants, including 88 men and 151 women, aged 65 years and older were selected from health centers in the district of Seoul, Gyeonggi province, and Incheon, in Korea. Dietary patterns were determined using Reduced Rank Regression (RRR methods with responses regarding vitamin B6, vitamin C, and iron intakes, based on both a one-day 24-h recall and a food frequency questionnaire. Cognitive function was assessed using the Korean-Mini Mental State Examination (K-MMSE. Multivariable logistic regression models were used to estimate the association between dietary pattern score and the risk of mild cognitive impairment. A total of 20 (8% out of the 239 participants had mild cognitive impairment. Three dietary patterns were identified: seafood and vegetables, high meat, and bread, ham, and alcohol. Among the three dietary patterns, the older adult population who adhered to the seafood and vegetables pattern, characterized by high intake of seafood, vegetables, fruits, bread, snacks, soy products, beans, chicken, pork, ham, egg, and milk had a decreased risk of mild cognitive impairment compared to those who did not (adjusted odds ratios 0.06, 95% confidence interval 0.01–0.72 after controlling for gender, supplementation, education, history of dementia, physical activity, body mass index (BMI, and duration of sleep. The other two dietary patterns were not significantly associated with the risk of mild cognitive impairment. In conclusion, high consumption of fruits, vegetables, seafood, and protein foods was significantly associated with reduced mild cognitive impairment in older Korean adults. These results can contribute to the establishment of

This study evaluated antismoking advertisements in South Korean television by drawing upon a Health Communication article by Cohen, Shumate, and Gold (2007) and on Gold, Cohen, and Shumate's (2008) typology. This study examined the theories and messages in South Korean antismoking advertisements. First, South Korean antismoking advertisements primarily targeted adults. In addition, the advertisements for adults normally used statistical evidence, whereas those for adolescents often used testimonial evidence. In terms of the type of performance, narration was often used in advertisements for both adults and adolescents. Second, the most prevalent persuasive health message used social norms, whereas the most prevalent affective appeal used fear appeals. Third, antismoking advertisements in South Korea mentioned more benefits of not smoking than barriers to not smoking. This study also identified the message difference in the U.S. and South Korean antismoking advertisements.

Full Text Available Abstract Background Recently there has been a growing interest in healthcare quality control in Korea. We examined the association between patient factors and quality indicators of diabetic care among Korean adults with diabetes. Methods We obtained a sample of 335 adults aged 20 or older diagnosed with diabetes from the 2005 Korean National Health and Nutrition Examination Survey. Patient factors were divided into two categories: socioeconomic position and health-related factors. Quality indicators for diabetes care were defined as receiving preventive care services for diabetes complications (e.g., fundus examination, microalbuminuria examination, diabetes education and diabetes-related clinical outcomes (e.g., HbA1c, blood pressure, LDL-cholesterol. We performed multiple logistic regression analyses for each quality indicator. Results We found that people with lower education levels or shorter duration of diabetes illness were less likely to receive preventive care services for diabetes complications. Women or people with longer duration of diabetes were less likely to reach the glycemic target. Obese diabetic patients were less likely to accomplish adequate control of blood pressure and LDL-cholesterol. Conclusions Several factors of patients with diabetes, such as education level, duration of illness, gender, and obesity grade are associated with the quality of diabetes care. These findings can help inform policy makers about subpopulations at risk in developing a public health strategy in the future.

Introduction: Toxic heavy metals have adverse effects on human health. However, the risk of hematuria caused by heavy metal exposure has not been evaluated. Methods: Data from 4701 Korean adults were obtained in the Korean National Health and Nutritional Examination Survey (2008–2010). Blood levels of the toxic heavy metals cadmium, lead, and mercury were measured. Hematuria was defined as a result of ≥+1 on a urine dipstick test. The odds ratios (ORs) for hematuria were measured according to the blood heavy metal levels after adjusting for multiple variables. Results: Individuals with blood cadmium levels in the 3rd and 4th quartiles had a greater OR for hematuria than those in the 1st quartile group: 3rd quartile, 1.35 (1.019–1.777; P=0.037); 4th quartile, 1.52 (1.140–2.017; P=0.004). When blood cadmium was considered as a log-transformed continuous variable, the correlation between blood cadmium and hematuria was significant: OR, 1.97 (1.224–3.160; P{sub trend}=0.005). In contrast, no significant correlations between hematuria and blood lead or mercury were found in the multivariate analyses. Discussion: The present study shows that high cadmium exposure is associated with a risk of hematuria. -- Highlights: • A high level of blood cadmium is associated with a high risk of hematuria. • This correlation is independent of several confounding factors. • Blood levels of lead and mercury are not associated with risk of hematuria. • This is the first study on the correlation between cadmium exposure and hematuria risk.

The Body Image Scale (BIS) developed in collaboration with the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Study Group is a brief questionnaire for measuring body image concerns in patients with cancer. This study sought to assess the reliability and validity of the Korean version of the Body Image Scale (K-BIS). The participants consisted of 155 postoperative breast cancer patients (56 breast conserving surgery, 56 mastectomy, and 43 oncoplastic surgery). Subjects were evaluated using the K-BIS, the Body-Esteem Scale for Adolescents and Adults (BESAA), the Rosenberg Self-Esteem Scale (RSES), the Hospital Anxiety and Depression Scale (HADS), and the World Health Organization Quality of Life Scale Abbreviated Version (WHOQOL-BREF). Test-retest reliability and internal consistency were examined as a measure of reliability and validity was evaluated by convergent validity, discriminant validity and factor analysis. Cronbach's α value was 0.943. The total score of the K-BIS was negatively correlated with the BESAA (r=0.301, p59% variance. The K-BIS showed good reliability and validity for assessment of body image in Korean breast cancer patients.

To clarify the clinical characteristics of reticular pseudodrusen in Korean patients. Retrospective, observational, consecutive case series. A total of 255 eyes of 130 patients diagnosed with reticular pseudodrusen were evaluated. Reticular pseudodrusen were diagnosed by characteristic fundus findings using ophthalmoscopy, color fundus photography with blue-channel examination, near-infrared photography, red-free photography, autofluorescence imaging, fluorescein angiography, indocyanine green angiography, and spectral-domain optical coherence tomography. Age-related macular degeneration (AMD) was determined by the International Classification and Grading System. The mean age was 72.6 ± 9.0 years (range, 43 to 92 years). Most reticular pseudodrusen patients had bilateral disease (97.7%), with a female preponderance (86.2%). All 3 patients who showed unilateral reticular pseudodrusen had neovascular AMD in the eye with no reticular pseudodrusen. AMD was found in 183 eyes (71.8 %), among which early AMD was found in 115 eyes (45.1%), geographic atrophy was found in 41 eyes (16.1%), and neovascular AMD was found in 27 eyes (10.6%). The mean age of patients with AMD and with no AMD was 73.7 ± 9.2 years (range, 58 to 92 years) and 69.9 ± 11.7 years (range, 43 to 90 years), respectively, and there was a statistical difference between these 2 groups (P < .05). Classic choroidal neovascularization was found in 13 eyes (48.1%), and occult choroidal neovascularization was found in 14 eyes (51.9%) in the neovascular AMD group. Reticular pseudodrusen occurs in Koreans, and clinical manifestations of reticular pseudodrusen in Koreans did not differ significantly from those described in white persons. However, our study demonstrated a higher rate of bilaterality compared with those previously reported, and geographic atrophy was found to be associated more commonly with reticular pseudodrusen than with neovascular AMD. Ethnical differences may be associated with these

2015-01-01

We evaluated the psychometric properties of the Korean version of the Self-Efficacy for Exercise Scale (SEE-K). The SEE-K consists of nine items and was translated into Korean using the forward-backward translation method. We administered it to 212 community-dwelling older adults along with measures of outcome expectation for exercise, quality of life, and physical activity. The validity was determined using confirmatory factor analysis and Rasch analysis with INFIT and OUTFIT statistics, which showed acceptable model fit. The concurrent validity was confirmed according to positive correlations between the SEE-K, outcome expectation for exercise, and quality of life. Furthermore, the high physical activity group had higher SEE-K scores. Finally, the reliability of the SEE-K was deemed acceptable based on Cronbach's alpha, coefficients of determination, and person and item separation indices with reliability. Thus, the SEE-K appears to have satisfactory validity and reliability among older adults in South Korea. Copyright © 2015 Elsevier Inc. All rights reserved.

Patients are free to choose conventional or Korean medicine treatment under the dual medical system in Korea, and the prevalence of patients who choose Korean medicine treatment for whiplash-associated disorders (WADs) is high. This study analyzed the sociodemographic characteristics and medical service use in this population to provide healthcare providers with basic usage information of complementary and alternative medicine for WAD. A total of 8291 outpatients who registered under automobile insurance coverage and visited the main branch of Jaseng Hospital of Korean Medicine from April 1, 2014 to August 10, 2016 were included. Data on sociodemographic characteristics, symptoms, and accident and treatment-related details were collected from electronic medical records. Univariate and multivariate regression analyses were performed to identify baseline factors predictive of total treatment duration. The most prevalent demographic of patients who chose Korean medicine for WAD treatment was males in their thirties whose initial visit to the hospital was 16.1 ± 94.1 days from the accident. Neck pain accompanied by low back pain (57.0%) was the most common complaint, and for singular pain, neck pain (13.5%) was the most prevalent. Baseline numeric rating scale (NRS) pain levels were generally moderate (4-6) regardless of area. Patients received 7.2 ± 10.2 sessions of treatment for 32.6 ± 55.3 days. The most commonly prescribed treatment modalities in order of highest frequency were acupuncture, cupping, pharmacopuncture, and herbal medicine, which collectively accounted for > 90% of treatments. Acupuncture was administered 29.0 ± 40.8 times, and cupping 14.0 ± 18.7 times as the two highest frequency treatments. In multivariate regression analysis, longer treatment periods were found to be associated with higher NRS, older age, and delayed initial visits at baseline. This study highlights the characteristics and Korean medicine use of WAD

2013-01-01

Developmental psychologists have shown interest in the development of psychological essentialism among children; that is, a belief that certain psychological characteristics (such as personality) are relatively stable and unchanging. Although previous studies have shown that children are essentialistic about human traits, and the coherence among various essentialism dimensions increases with age, moderating cultural factors in the development of essentialism, especially among Asian children, have received little attention. Using the methodologies of Gelman, Heyman, and Legare (2007), levels of psychological essentialism among Korean children and adults were measured, and compared with the original US data. Results demonstrated cross-cultural similarity in the development of coherence in essentialistic thought, and difference in the level of essentialism among adult participants. The present findings imply that different cultural values between Asians and Westerners can play a role in the developmental trajectory of psychological essentialism.

This study aimed to investigate the prevalence, correlates, comorbidities, and suicidal tendencies of problematic game use in a nationally representative sample of Korean adults. Of the 6022 subjects who participated in the 2011 Korean Epidemiologic Catchment Area study and completed the Composite International Diagnostic Interview 2.1, 1397 game users were evaluated for problematic game use using 9-item DSM-5 proposed criteria for Internet gaming disorder. Respondents who responded "yes" to five or more of the nine DSM-5 criteria were considered as problematic game users and the reminders were considered as normal game users. 4.0% (56/1397) of game users were classified as a problematic game user. Problematic game users were more likely to be in younger age group and live in urban area compared with normal game user. Problematic game use was positively associated with several psychiatric disorders including nicotine use disorder, depressive disorder, and anxiety disorder, but not associated with alcohol use disorder and obsessive-compulsive disorder, after adjusting for age, sex, and residential area. Problematic game use was significantly and positively associated with suicide plans, after controlling for psychiatric disorders as well as socio-demographic factors. Problematic game use is relatively prevalent in Korean adult population and highly comorbid with other psychiatric disorders and suicidality. Therefore, preventive strategy for problematic game use is needed for game users who were more likely to be addicted such as young adults in urban area, and mental health screening and appropriate treatment are needed for individuals with problematic game use.

What Accounts for the Relationship Between Internet Use and Suicidal Ideation of Korean Older Adults? A Mediation Analysis.

Jun, Hey Jung; Kim, Myoung-Yong

2017-09-01

This study sought to examine the relationship between Internet use and suicidal ideation in Korean older adults and the mediating roles of social relationships and depressive symptoms. A nationally representative sample of older adults aged 50 or older (N = 6,306), from four waves of the Korean Welfare Panel Study, was used in the analyses. All analyses were conducted using generalized estimation equations, and the mediation effects of social relationship satisfaction and depression in the relationship between Internet use and suicidal ideation were calculated using the product-of-coefficients approach. Internet use was linked with lower levels of suicidal ideation directly and indirectly via the protective effects of Internet use on lowering depression, which was partially mediated by the positive influence Internet use has on older adults' social relationship satisfaction. The results support previous theories about the relationship between social relationships, depression, and suicidal behavior and prior results about how the Internet might confer mental and social health benefits to older adults. This suggests that the Internet is an important social and health activity that contributes to lowering suicidal ideation in older adults. © The Author 2016.

The primary objective of this study was to assess the overall safety and tolerability of atomoxetine in Korean, Chinese, and Taiwanese adults with attention-deficit/hyperactivity disorder (ADHD). A total of 44 patients aged ≥18 years who met the Conners' Adult ADHD Diagnostic Interview for DSM-IV diagnostic criteria for ADHD were enrolled from China, Korea, and Taiwan. In this open-label, dose-escalation study, patients received atomoxetine orally once daily over a period of eight weeks, starting at 40 mg/day (one week) up to a maximum dosage of 120 mg/day. Tolerability was evaluated by rate of discontinuation due to adverse events. Safety was assessed by recording all adverse events, laboratory tests, vital signs, and electrocardiograms. ADHD symptoms were evaluated by the Conners' Adult ADHD Rating Scale-Investigator Rated: Screening Version (CAARS-Inv:SV) for efficacy assessment. Thirty-four patients (77.3%) completed the study. Atomoxetine was well tolerated with a discontinuation rate of 2.3% (1/44) due to adverse events. The most commonly reported adverse events were nausea, dizziness, and somnolence. The mean change from baseline to endpoint in CAARS-Inv:SV total ADHD symptom score was -12.5 (P atomoxetine clinical trial in adult patients with ADHD in China, Korea, and Taiwan. Atomoxetine was well tolerated in doses of up to 120 mg/day with no unknown safety concerns. Copyright © 2012 Blackwell Publishing Asia Pty Ltd.

Purpose Recent reports suggest the association of human papilloma virus (HPV) with retinoblastoma. This study was performed to elucidate whether HPV infection is related to retinoblastoma among Koreans. Methods A total of 54 cases diagnosed with retinoblastoma were enrolled from Seoul National University Children's Hospital and Seoul Metropolitan Government-Seoul National University Boramae Medical Center. Presence of human papilloma viral DNA was detected by in situ hybridization in formalin-fixed paraffin-embedded retinoblastoma tissues using both probes against high- and low risk HPV types. Results The mean age at diagnosis was 22.0 months (range, 1.1 to 98.0 months), and the mean age at enucleation was 27.8 months (range, 1.5 to 112.7 months) among the 54 patients with retinoblastoma. HPV was not detected in any of the retinoblastoma samples using either high risk or low risk HPV probes. Conclusions Our study, being the first study in the Korean population, proposes that HPV infection may have no causal relationship with retinoblastoma in Koreans. PMID:24082775

According to Healthy People 2010, health communication is an important tool to reduce health disparities. Communication channels in which people prefer to receive health information may differ by race/ethnicity. One of the main challenges in designing an effective health communication program is to identify the most trusted and most often used channels of health information by Asian older adults. The aim of this study is to determine which health communication channels can be used to promote healthy lifestyles among older adults. A non-probability, convenience-sampling technique was used to recruit Korean (n = 9) and Asian Indian (n = 9) older adults from two senior centers in New York City. The findings from the two focus groups identified three distinct channels used by Asian older adults when obtaining health information: interpersonal (i.e., health care providers, word of mouth), mass media (i.e., ethnic mass media sources), and community specific (i.e., religious organizations, community centers). Health communication is an important area for prevention. Increased efforts are needed to develop culturally appropriate health messages and equally important to deliver these messages in the context in which Asian older adults trust and use the most.

Purpose To determine whether proinflammatory cytokine genes were potential susceptibility candidate genes for Korean patients with non-Sjogren dry eye, we investigated the association of the interleukin 1 beta (IL1B), interleukin 6 (IL6), and interleukin 6 receptor (IL6R) variations with this disease in Korean patients. Methods Genomic DNA was extracted from blood samples of unrelated non-Sjogren dry eye patients and healthy control individuals who visited the Eye Center and Health Promotion Center of St. Mary’s Hospital in Seoul, Korea. For screening genetic variations in proinflammatory cytokine genes, the 511 (rs16944) and 31 (rs1143627) positions in the promoter region of IL1B, rs1143634 in exon 5 of IL1B, rs1800795 of the IL6 promoter, and Asp358Ala (rs8192284) of IL6R were genotyped using the polymerase chain reaction, restriction fragment length polymorphisms, and direct sequencing. Results Among the polymorphisms, rs1143634 (F105F) in exon 5 of IL1B was significantly different between the patient and control groups. The frequency of the C/T genotype in dry eye patients was decreased relative to that of the control subjects (10.4% versus 3.9%, p=0.043, OR=3.337). For the IL6R gene, the genotypic and allelic distribution of rs8192284 was different between the dry eye patients and the controls: CC genotype (p=0.017, OR=2.12) and C allele (OR=1.26). Conclusions This is the first report of genetic variation screening of proinflammatory cytokine genes in Korean non-Sjogren dry eye patients. It is suggested that rs1143634 of IL1B and rs8192284 of IL6R act as susceptibility variations in Korean non-Sjogren dry eye patients. PMID:22128229

The Manchester-Oxford Foot Questionnaire (MOXFQ) is a practical, reliable, and valid questionnaire for hallux valgus surgery and has been translated into several languages. However, the MOXFQ has not been translated into Korean. In the present study, we aimed to translate and evaluate the validity and reliability of the Korean version of the MOXFQ for patients affected by hallux valgus. In accordance with the guidelines of cross-cultural adaptation, we translated the English version of MOXFQ into Korean and then backward translated it into English. We sent out letters that included the Korean version of the MOXFQ, a visual analog scale measure of pain, and a validated Korean version of the short-form 36-item Health Survey to 135 patients with hallux valgus. A retest was administered after 2 weeks. Of the 135 patients, 104 responded to the first questionnaire, and 82 of the first-time responders returned their second questionnaires. We evaluated the test-retest reliability, internal consistency, concurrent validity, and construct validity of the Korean version of the MOXFQ. The intraclass correlation coefficient for test-retest reliability was 0.82 for the total MOXFQ and ranged from 0.81 to 0.82 for the 3 subscales. Cronbach's alpha for the total MOXFQ was 0.85 and ranged from 0.8 to 0.92 for the 3 subscales. Concurrent and construct validity was supported by significant correlation with the visual analog scale and short-form 36-item Health Survey subscale scores. The Korean version of the MOXFQ was tested, and it was found to be a valid and reliable instrument for patients with hallux valgus. Copyright © 2016 American College of Foot and Ankle Surgeons.

To assess impaired quality of life (QOL) of Korean patients with thyroid eye disease (TED) using the TED-QOL questionnaire, to evaluate the adaptability of the questionnaire, and to assess the correlation between TED-QOL and scales of disease severity. Prospective, cross-sectional study. Total of 90 consecutive adult patients with TED and Graves' disease were included in this study. TED-QOL was translated into Korean and administered to the patients. The results were compared with clinical severity scores (clinical activity score, VISA (vision loss (optic neuropathy); inflammation; strabismus/motility; appearance/exposure) classification, modified NOSPECS (no signs or symptoms; only signs; soft tissue; proptosis; extraocular muscle; cornea; sight loss) score, Gorman diplopia scale, and European Group of Graves' Orbitopathy Classification). Clinical scores indicating inflammation and strabismus in patients with TED were positively correlated with overall and visual function-related QOL (Spearman coefficient 0.21-0.38, p < 0.05). Clinical scores associated with appearance were positively correlated with appearance-related QOL (Spearman coefficient 0.26-0.27, p < 0.05). In multivariate analysis, age, soft-tissue inflammation, motility disorder of modified NOSPECS, and motility disorder of VISA classification had positive correlation with overall and function-related QOL. Sex, soft-tissue inflammation, proptosis of modified NOSPECS, and appearance of VISA classification had correlation with appearance-related QOL. In addition, validity of TED-QOL was proved sufficient based on the outcomes of patient interviews and correlation between the subscales of TED-QOL. TED-QOL showed significant correlations with various objective clinical parameters of TED. TED-QOL was a simple and useful tool for rapid evaluation of QOL in daily outpatient clinics, which could be readily translated into different languages to be widely applicable to various populations.

The author conducted an experiment using P-A Cephalography of 242 male and female subjects of ages ranging 2-6, 7- 15, and adult group. By means of Nakago's method of measurement, the standard value of Korean was obtained. The results were as follows; 1. In the group of an age, the male value was slightly greater than female value. 2. In each age group the difference between the right and left widths could be recognizable, however, it was not much great. 3. In each group, regardless of sex, the growth relation was clearly distinguishable at PO, ARI, ARE, MG, AG, and CAW. 4. When the standard value of adult Korean was compared with that of Japanese, that of Japanese was great with respect to the width of maxillary portion and that of Korean was great with respect to the width of mandibular portion. 5. Maximum head width of white man was almost similar to that of Korean, however, maxillary alveolar base width of white man was considerably small or the dental arch was narrow.

Full Text Available Background : Using BMI as an independent variable is the easiest way to estimate percent body fat. Thus far, few studies have investigated the development and cross-validation of an equation for estimating the percent body fat of Korean adults according to the BMI. The goals of this study were the development and cross-validation of an equation for estimating the percent fat of representative Korean adults using the BMI. Methods : Samples were obtained from the Korea National Health and Nutrition Examination Survey between 2008 and 2011. The samples from 2008-2009 and 2010-2011 were labeled as the validation group (n=10,624 and the cross-validation group (n=8,291, respectively. The percent fat was measured using dual-energy X-ray absorptiometry, and the body mass index, gender, and age were included as independent variables to estimate the measured percent fat. The coefficient of determination (R², standard error of estimation (SEE, and total error (TE were calculated to examine the accuracy of the developed equation. Results : The cross-validated R² was 0.731 for Model 1 and 0.735 for Model 2. The SEE was 3.978 for Model 1 and 3.951 for Model 2. The equations developed in this study are more accurate for estimating percent fat of the cross-validation group than those previously published by other researchers. Conclusion : The newly developed equations are comparatively accurate for the estimation of the percent fat of Korean adults.

As the number of cancer survivors increases, suicide risk approaches that of the general population. We therefore investigated suicide rates and risk factors among Korean cancer patients. We observed 816,295 cancer patients for 3,007,294 person-years from 1993 to 2005 through a nationwide cancer registry. We calculated their sex- and age-standardized mortality ratios (SMR) and studied suicide risk factors using rate ratios (RR) based on a log-linear Poisson regression model. Compared with the Korean general population, the suicide rate among cancer patients was high [SMR, 2.00; 95% confidence interval (95% CI), 1.91-2.08]. The rates were highest in the year following the cancer diagnosis (SMR, 3.45; 95% CI, 3.19-3.73) and were still elevated 5 years later (SMR, 1.23; 95% CI, 1.12-1.36). The clinical groups at highest risk were male pancreas cancer patients (SMR, 6.01; 95% CI, 4.33-8.33) and female lung cancer patients (SMR, 3.55; 95% CI, 2.55-4.94). The sociodemographic groups at highest risk were those who had no spouse versus those who were married (RR, 1.50; 95% CI, 1.35-1.68), those who were not employed versus those who were (RR, 1.39; 95% CI, 1.26-1.54), and those who did not have high school education versus those who had (RR, 1.52; 95% CI, 1.30-1.79). Korean cancer patients are at increased risk of suicide. Both clinical and sociodemographic factors play a role. There is a need for social support and suicide prevention strategies for cancer survivors in Korea. (c)2010 AACR.

It is already well known that many factors are involved in maintaining normal blood glucose level. The amount and components of meal are also thought to be some of the factors which affect the blood glucose and insulin levels. It is reported that as for Koreans sugar takes up over 75% out of 2,098 kcal, the average daily calorie intake per adult. It implies that Koreans take a high-sugar diet compared with Westerners who take 40-50% of sugar out of their total average daily calorie. For the purpose of studying diurnal variations in serum glucose, insulin and C-peptide of normal Koreans adults based on ordinary Korean diet, we selected 13 normal Korean male adults and divided them into two groups, Group I (7 persons) and Group II (6 persons). We put Group I on 3,100 kcal and 75% sugar diet, and Group II on 2,100 kcal and 69% sugar diet per day for over 4 days. Serum glucose, insulin and C-peptide were checked every 30 minutes or every hour throughout 2 hour. Results are as follows: 1. As for serum glucose level, in the preprandial fasting state in the morning, mean±S.D. of Group I was 91.1±3.2 mg%, while that of Group II is 82.5±4.4 mg%. Both groups showed peaks of increased glucose level t postprandial 1 hour after each meal. The peak returned to the level shown during the fasting state at postprandial 1 hour after breakfast while the relatively high glucose levels were maintained respectively even for 2 or 3 hours after lunch and dinner. 2. As for serum insults level, Group I showed mean±S.D. of 14.7±3.0 μU/ml while Group II shows that of 7.0±2.6 μU/ml in the fasting state. Group I particularly showed the largest peak from preprandial a half or one and half an hour to postprandial one hour of lunch, and made relatively small peaks (47.7±10.8 μU/ml) at postprandial 1 hour after breakfast and dinner. No such large peak was marked in Group II, though it showed relatively similar patterns of peak after each meal. 3. As for C-peptide, in the fasting state

The purpose of the present study was to investigate the relationship between Korean language-specific dysgraphia and unilateral spatial neglect in 31 right brain stroke patients. All patients were tested for writing errors in spontaneous writing, dictation, and copying tests. The dysgraphia was classified into visuospatial omission, visuospatial destruction, syllabic tilting, stroke omission, stroke addition, and stroke tilting. Twenty-three (77.4%) of the 31 patients made dysgraphia and 18 (58.1%) demonstrated unilateral spatial neglect. The visuospatial omission was the most common dysgraphia followed by stroke addition and omission errors. The highest number of errors was made in the copying and the least was in the spontaneous writing test. Patients with unilateral spatial neglect made a significantly higher number of dysgraphia in the copying test than those without. We identified specific dysgraphia features such as a right side space omission and a vertical stroke addition in Korean right brain stroke patients. In conclusion, unilateral spatial neglect influences copy writing system of Korean language in patients with right brain stroke.

The purpose of this study was to compare the effects of Korean mindfulness-based stress reduction (K-MBSR), walking, and patient education regarding diabetes mellitus (DM) on stress response, glycemic control, and vascular inflammation in patients with diabetes mellitus. A cluster randomized trial including 56 adults with diabetes mellitus (K-MBSR group = 21, walking group = 18, patient education group = 17) was conducted between 13 July and 14 September 2012. The questionnaire included the Diabetes Distress Scale and Perceived Stress Response Inventory. Fasting blood samples were used to measure levels of cortisol, blood glucose, plasminogen activator inhibitor-1 (PAI-1), and tissue plasminogen activator (t-PA). There were no statistically significant differences between the effects of K-MBSR, walking, and patient education on stress, glycemic control, or vascular inflammation. However, in the K-MBSR and walking groups, significant reductions in the levels of serum cortisol and PAI-1 were observed. A significant reduction in psychological responses to stress was observed in the walking and patient education groups. Longitudinal studies could provide better insight into the impact of K-MBSR, walking, and patient education on health outcomes in adults with diabetes mellitus. © 2015 Wiley Publishing Asia Pty Ltd.

The prevalence of metabolic syndrome is consistently increasing among Korean adults and is reported to be particularly high among older adults in Korea. This paper reports the prevalence of metabolic syndrome and identifies the association between metabolic syndrome and physical activity in Korean older adults. Subjects of this study were 3653 older adults who participated in the fourth Korean National Health and Nutrition Examination Survey during the years 2007-2009. The prevalence of metabolic syndrome in the study population was 46.84%. The prevalences of abdominal obesity, elevated fasting glucose, elevated triglycerides, reduced high-density lipoprotein cholesterol, and elevated blood pressure were 39.51, 45.53, 39.55, 48.24, and 69.14%, respectively, in the study population. Compared to subjects who reported low levels of physical activity, the odds ratios of metabolic syndrome for those who were moderately active and highly active were 0.93 and 0.63, respectively. Nurses should develop metabolic syndrome management programs that are tailored to the needs of the targeted group and that include individually adapted physical activity programs to promote health. © 2013 Wiley Publishing Asia Pty Ltd.

Culture has been pinpointed as a culprit of disparities in health insurance coverage between Korean immigrants and other ethnic groups. This study explored specific mechanisms by which culture influences a decision to buy health insurance among self-employed Korean immigrants living in ethnic enclaves by focusing on the structure and functions of social networks. Between March and June 2015, we recruited 24 Korean immigrant adults (aged 18 or older) who identified as self-employed and being uninsured for substantial periods before 2014 in Southern California. Interviews were conducted in Korean, and Korean transcripts were translated into English by two bilingual interpreters. Using constant comparative analysis, we explored why participants didn't purchase health insurance after migrating to the United States and how their social networks influenced their decisions whether to purchase health insurance. Results indicate Korean immigrants sought health information from dense and homogeneous social networks whose members are mostly Korean immigrants embedded in similar social contexts. Social learning was frequently observed when people sought health care while uninsured. However, respondents often noted social ties do not provide helpful information about benefits, costs, and ways to use health insurance. "Koreans don't buy health insurance" was a dominant social norm reported by most respondents. Findings indicate that social learning and normative influence occur inside social networks and these mechanisms seemingly prevent purchasing of health insurance. In addition to the individual mandate in the Patient Protection and Affordable Care Act, more targeted approaches that consider the structure and functions of social networks could improve the public health of Korean immigrants.

This study assessed the association of dry eyes with depression and suicidal ideation in a Korean adult population. Data from 16408 participants (6972 men and 9436 women) aged ≥ 19 years included in the fifth Korea National Health and Nutrition Examination Survey, conducted from 2010-2012, were analyzed. For dry eyes, surveys of previous diagnosis of dry eye disease (DED) by an ophthalmologist and experience of subjective dry eye symptoms were separately used. Diagnosis of depression and suicidal ideation were obtained via responses to an interviewer-assisted questionnaire, and questions were asked in a closed-ended response format. Logistic regression was used to examine the associations between dry eyes, depression, and suicidal ideation. DED diagnosis exhibited an odds ratio (OR) of 1.32 (95% confidence interval [CI] 1.11-1.57) for depression and 1.24 (95% CI 1.05-1.48) for suicidal ideation compared to those without DED, after adjusting for sex, age, education, occupation, household income, body mass index, smoking behavior, alcohol consumption, physical activity, hypertension, diabetes, dyslipidemia, thyroid diseases, major cardiovascular disease, and cancer. Similarly, the adjusted OR (95% CI) of dry eye symptoms was 1.50 (95% CI 1.30-1.73) for depression and 1.47 (95% CI 1.27-1.70) for suicidal ideation. Our findings suggest that dry eyes (either DED diagnosis or dry eye symptoms) may be associated with the prevalence of depression and suicidal ideation in the Korean adult population.

Inadequate vitamin D status is highly prevalent in the Korean population, especially among young adults. Nonetheless, correlates of suboptimal vitamin D levels in young adults are not well defined. This study aimed to investigate potentially modifiable determinants of vitamin D levels in young adults in Korea. This cross-sectional study was based on health check-up data from 3,450 healthy male and female university students aged 18-29 yr in Seoul between April and May 2013. Serum 25-hydroxyvitamin D [25(OH)D] levels were determined using chemiluminescent immunoassay. Anthropometric data were measured, and lifestyle, dietary, and sociodemographic factors were obtained through self-administered questionnaires. General linear regression was used to assess correlates of serum 25(OH)D levels. The mean serum 25(OH)D level was 11.1 ng/mL, and the prevalence of 25(OH)D levels less than 10 ng/mL was 44.7% (39.5% in men, 50.2% in women). In a final multivariable model, significant positive correlates of serum 25(OH)D were older age, male sex, increased physical activity, sunlight exposure ≥ 30 min/day, eating breakfast regularly, consumption of dairy and fatty fish, and use of vitamin D-containing supplements. In contrast, significant inverse correlates were obesity (body mass index, BMI ≥ 25 kg/m(2)) or underweight (BMI instant noodles and sugar-sweetened beverages. In conclusion, many modifiable lifestyle and dietary factors were associated with low serum 25(OH)D levels in Korean young adults. Further studies on potential mechanisms of the correlates and optimal strategies to improve vitamin D status in this vulnerable subpopulation are warranted.

CT may be valuably used in determination of proptosis. Normal value of eyeball protrusion was measured in normal Koreans using CT. Among 86 Koreans, 26 have normal both eyes, but 60 have one normal eye with one abnormal eye (chiefly, proptosis and and eyeball tumor). The results of 112 eyes are as follows: Absolute measurement of 'a', that is, the distance between cornea and IZL (interzygomatic line) is 16.0±3.4 mm in male (for 63 eye), 15.7±4.0 mm in female for 49 eyes. Ratio of 'a' over 'A' (A-P diameter of eyeball) is 57±12% is male (for 63 eye), 57±14% in female (for 49 eye) Discrepancy of eyeball protrusion between both eyes is 0.67±1.5 mm (for 26 adults). Practically, normal range of eyeball prtotrusion ('a') is 12.6 mm < male < 19.4 mm, 11.7 mm < female < 19.7 mm. 'a/A' ratio over 70% and over 2mm discrepancy between both eyes are also suggested as genuine exophthalmos

This study aimed to examine whether blood levels of heavy metals, such as lead, mercury and cadmium, are related with pulmonary function in Korean adults. This investigation included 870 Korean adults (≥40 years) who received pulmonary function testing in the Korea National Health and Nutrition Examination Survey (KNHANES) V-2, 2011. Data of blood levels of heavy metals, pulmonary function tests and anthropometric measurements were acquired. Blood lead levels showed inverse correlations with the FEV 1 /FVC ratio before (r=−0.276, p<0.001) and after adjustment of multiple compounding factors (r=−0.115, p=0.001). A logistic multiple regression analysis revealed that blood lead levels were a significant influencing factor for the FEV 1 /FVC ratio (β=−0.017, p=0.001, adjusted R 2 =0.267). The odds ratios (ORs) for the FEV 1 /FVC ratio were significantly lower in the highest tertile group of the blood lead levels than in the lowest tertile group in Model 1 (OR=0.007, 95% CI=0.000−0.329) and Model 2 (OR=0.006, 95% CI=0.000−0.286). These findings imply that environmental exposure to lead might be an important factor that may cause airflow limitations in Korean adults. - Highlights: • Blood lead levels showed inverse correlations with the FEV 1 /FVC ratio. • Blood lead level was a significant influencing factor for the FEV 1 /FVC ratio. • ORs for FEV 1 /FVC were lower in the highest blood lead group than in the lowest group. • Environmental exposure to lead might be an important factor for airflow limitations

Korean immigration peaked in the mid-1980s, so that large cohorts of post-1965 immigrants are now approaching or entering retirement. As the baby boomer generation ages, few studies have examined how the lack of retirement savings and eldercare plans combined with cultural expectations such as filial piety may pose challenges for aging Korean immigrants and their adult children. This exploratory study examines attitudes and beliefs among 1.5 and 2nd generation Korean American adults regarding filial expectations and support for aging immigrant parents. In-depth interviews conducted with 124 adult children of immigrants show that their attitudes and beliefs around filial care were primarily motivated by feelings of gratitude and a strong sense of responsibility toward their parents. In addition, because Korean immigrant parents often face language and financial barriers, adult children were preparing themselves for future support of their parents' finances, health care and long-term care needs. Although both adult sons and daughters expressed a desire to care for their parents, adult daughters often discussed in detail their concerns and worries about future care of their parents. The findings of this paper illustrate how the intersections of gender, culture, and class inform attitudes and beliefs regarding aging and family support among Korean American families.

The study was made on the facial profile of the normal Korean adults using the roentgenographic cephalograms. The subjects consisted of 50 male and 50 female with normal occlusion. The measurements were made of the facial angles in skeletal pattern and depth, height and the length in the soft tissue profile. The mean and standard deviations from the subjects were calculated and compared with the samples of male and female. The authors have drawn the conclusions as follows: 1. Compared with the angulation in skeletal patterns, there were no differences between both sexes. 2. Individual variations of the lower face were larger than those of the upper face in most measuring points. 3. In general, facial heights were lesser than facial depth in sexual differences. 4. Most dimensions of the facial depth, height and length of the male were larger than those of female.

Full Text Available Background and Objective Individuals have a unique circadian preference, which is based on differences in endogenous rhythm and environmental factors. There has been no study on the relationship between the morningness-eveningness (ME preference and the polymorphisms of PER2 and CRY1 genes, which may play an essential role in the modulation of circadian rhythm. Our present study aims to examine the difference in the polymorphisms of PER2-2221A/G and CRY1-2790T/G, which are related to a greater cancer risk, according to the ME preference. Methods The Korean version of the Morningness-Eveningness Questionnaire was administered and buccal DNA samples were obtained from 425 Korean adults aged 18 years or older. We excluded subjects who were being treated for sleep disorders or those with shift work. 47 morning type (MT (age: 44.57 ± 12.33, M:F = 14:33 subjects, 59 neither type (NT (age: 35.20 ± 9.53, M:F = 20:39 subjects and 51 evening type (ET (age: 28.80 ± 8.03, M:F = 14:37 subjects were finally included in the present study. The above candidate single nucleotide polymorphisms were analyzed by DNA sequencing or a SNaPshot assay. Results For the PER2-2221A/G and CRY1-2790T/G, there were no significant differences in the genotype distribution, allele frequency, or proportion of G allele positive subjects between the MT and ET groups. There was no significant difference in the mean scores of the MEQ-K, KESS, or PSQI between G allele positive and negative subjects for either PER2-A2221A/G or CRY1-2790T/G. Conclusions Our study did not support the association of the ME preference with the PER2-2221 A/G and CRY1-2790T/G in Korean adults.

The aim of the present study was to evaluate the associations between dietary patterns and blood levels of lead and mercury in Korean adults. A total of 858 Korean adults (≥20 years) who participated in the Korea National Health and Nutrition Examination Survey (KNHANES) V-1 2010 were included in this study. Data of biochemical measurements including blood lead and mercury levels, nutrients intakes and anthropometric measurements were acquired. 'Balanced diet', 'Grain and kimchi', and 'Alcohol and noodle' dietary patterns were derived from a factor analysis, and the subjects were divided into tertiles by each dietary pattern score. A logistic multiple regression analysis showed that the balanced diet pattern was negatively associated with blood levels of lead before and after adjustment. On the other hand, the alcohol and noodle pattern was positively associated with blood lead and mercury levels. These results indicate that the alcohol and noodle dietary pattern characterized by high alcohol consumption and lack of various foods, and the balanced dietary pattern, including vegetable, fish, meat and milk intake, was associated with the blood concentrations of heavy metals in Korean adults.

Objective In 2002, the Korean Society for Affective Disorders developed the guidelines for the treatment of major depressive disorder (MDD), and revised it in 2006 and 2012. The third revision of these guidelines was undertaken to reflect advances in the field. Methods Using a 44-item questionnaire, an expert consensus was obtained on pharmacological treatment strategies for MDD 1) without or 2) with psychotic features, 3) depression subtypes, 4) maintenance, 5) special populations, 6) the choice of an antidepressant (AD) regarding safety and adverse effects, and 7) non-pharmacological biological therapies. Recommended first, second, and third-line strategies were derived statistically. Results AD monotherapy is recommended as the first-line strategy for non-psychotic depression in adults, children/adolescents, elderly adults, patient with persistent depressive disorder, and pregnant women or patients with postpartum depression or premenstrual dysphoric disorder. The combination of AD and atypical antipsychotics (AAP) was recommended for psychotic depression in adult, child/adolescent, postpartum depression, and mixed features or anxious distress. Most experts recommended stopping the ongoing initial AD and AAP after a certain period in patients with one or two depressive episodes. As an MDD treatment modality, 92% of experts are considering electroconvulsive therapy and 46.8% are applying it clinically, while 86% of experts are considering repetitive transcranial magnetic stimulation but only 31.6% are applying it clinically. Conclusion The pharmacological treatment strategy in 2017 is similar to that of Korean Medication Algorithm for Depressive Disorder 2012. The preference of AAPs was more increased. PMID:29397669

The aim of this study was to explore the association between sodium intake, as assessed by 24-h urinary sodium excretion, and various obesity parameters among South Korean adults. The associations of 24-h urinary sodium excretion and sodium intake calculated from the dietary questionnaire with obesity parameters also were compared. This multicenter, cross-sectional study analyzed data of 640 healthy adults from eight provinces in South Korea. Obesity was assessed by body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), and waist-to-height ratio (WHtR). Mean 24-h urinary sodium excretion was calculated from repeatedly collected 24-h urine samples. Participants' dietary intake was assessed by 24-h dietary recall interview on the days before 24-h urine collection. In both sexes, the means of all anthropometric measurements tended to increase proportionally with 24-h urinary sodium excretion quartiles, regardless of adjustment. Men in the highest quartile (Q4) of 24-h urinary sodium excretion had increased odds of obesity (as assessed by BMI, WC, WHR, and WHtR) compared with men in the three lower quartiles (Q1-Q3) of 24-h urinary sodium excretion. Women in Q4 of 24-h urinary sodium excretion exhibited a higher chance of general obesity and abdominal obesity. Sodium intake calculated from the dietary questionnaire was not significantly associated with obesity in either sex. In Korean adults, there was a positive association between higher sodium intake as assessed by 24-h urinary sodium excretion and obesity independent of energy intake. Copyright © 2017 Elsevier Inc.

Phthalates and bisphenol A (BPA) have been used extensively in many consumer products, resulting in widespread exposure in the general population. Studies have suggested associations between exposure to phthalates and BPA, and serum thyroid hormone levels, but confirmation on larger human populations is warranted. Data obtained from nationally representative Korean adults (n=6003) recruited for the second round of the Korean National Environmental Health Survey (KoNEHS), 2012-2014, were employed. Three di-(2-ethylhexyl) phthalate (DEHP) metabolites, along with benzyl-butyl phthalate (BBzP) and di-butyl phthalate (DBP) metabolites, and BPA were measured in subjects' urine. Thyroxine (T4), total triiodothyronine (T3), and thyroid-stimulating hormone (TSH) were measured in serum. The associations between urinary phthalates or BPA and thyroid hormone levels were determined. Urinary phthalate metabolites were generally associated with lowered total T4 or T3, or increased TSH levels in serum. Interquartile range (IQR) increases of mono-(2-ethyl-5-oxohexyl) phthalate (MEOHP), and mono-(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP) were associated with a 3.7% increase of TSH, and a 1.7% decrease of total T4 levels, respectively. When grouped by sex, urinary MEHHP levels were inversely associated with T4 only among males. Among females, mono-benzyl phthalate (MBzP) and mono-n-butyl phthalate (MnBP) levels were inversely associated with TSH and T3, respectively. In addition, negative association between BPA and TSH was observed. Several phthalates and BPA exposures were associated with altered circulatory thyroid hormone levels among general Korean adult population. Considering the importance of thyroid hormones, public health implications of such alteration warrant further studies. Copyright © 2017 Elsevier B.V. All rights reserved.

The changing role of employment status in marriage formation among young Korean adults

2017-01-01

Full Text Available Background: Despite a persistent decline in Korea's marriage rates over the past three decades, there is a striking lack of research on the transition to marriage among young Koreans. Similarly, few studies have examined how economic determinants have evolved over the past several decades, even as the Korean social and socioeconomic structure has undergone substantial transformation. Methods: This paper examines changes over time in the determinants of marriage formation in Korea, using employment history data from the Korean Labor and Income Panel Study (KLIPS on three cohorts of young adults born in the 1950s‒1970s. Results: Results indicate that, for women, the marital implications of being employed reversed over the three decades examined. While working decreased the odds of getting married for women born in the 1950s, it had no statistically significant effect for those born in the 1960s, and it strongly increased the odds of marriage for the most recent (1970s cohort of women. For their part, men's employment not only continued to positively predict getting married over the three decades, but its impact became stronger with each cohort, so that a man's odds of transition to first marriage was most strongly tied to his employment status for those born in the 1970s, as compared to earlier cohorts. Contribution: This study contributes to the literature by addressing the relationship between marriage timing and economic resources using more direct measures, examining the association between mandatory military service and marriage formation, and testing if determinants of marriage timing may evolve over time in Korea.

Background: Facial emotion recognition (FER) is impaired in individuals with frontotemporal dementia (FTD) and Alzheimer's disease (AD) when compared to healthy older adults. Since deficits in emotion recognition are closely related to caregiver burden or social interactions, researchers have fundamental interest in FER performance in patients with dementia. Purpose: The purpose of this study was to identify the performance profiles of six facial emotions (i.e., fear, anger, disgust, sadness, surprise, and happiness) and neutral faces measured among Korean healthy control (HCs), and those with mild cognitive impairment (MCI), AD, and FTD. Additionally, the neuroanatomical correlates of facial emotions were investigated. Methods: A total of 110 (33 HC, 32 MCI, 32 AD, 13 FTD) older adult participants were recruited from two different medical centers in metropolitan areas of South Korea. These individuals underwent an FER test that was used to assess the recognition of emotions or absence of emotion (neutral) in 35 facial stimuli. Repeated measures two-way analyses of variance were used to examine the distinct profiles of emotional recognition among the four groups. We also performed brain imaging and voxel-based morphometry (VBM) on the participants to examine the associations between FER scores and gray matter volume. Results: The mean score of negative emotion recognition (i.e., fear, anger, disgust, and sadness) clearly discriminated FTD participants from individuals with MCI and AD and HC [ F (3,106) = 10.829, p < 0.001, η 2 = 0.235], whereas the mean score of positive emotion recognition (i.e., surprise and happiness) did not. A VBM analysis showed negative emotions were correlated with gray matter volume of anterior temporal regions, whereas positive emotions were related to gray matter volume of fronto-parietal regions. Conclusion: Impairment of negative FER in patients with FTD is cross-cultural. The discrete neural correlates of FER indicate that emotional

Full Text Available BackgroundSeveral studies have suggested that elevated levels of hemoglobin A1c (HbA1c are associated with cardiovascular disease (CVD in nondiabetic individuals. However, it is unclear whether HbA1c levels can serve as a simple screening marker for increased CVD risk in nondiabetic individuals. Our objective was to evaluate the relationship between HbA1c levels and CVD risk using the Framingham risk score (FRS in older, apparently healthy nondiabetic Korean adults.MethodsWe retrospectively studied 2,879 Korean adults between the ages of 40 and 79 who underwent voluntary health check-ups at the Health Promotion Center of our hospital from July 2009 to June 2011. Subjects were subdivided based on their HbA1c levels into four groups: tertiles within the HbA1c normal tolerance range and a group for subjects with an increased risk for diabetes (IRD.ResultsThe mean FRS for the upper tertile (9.6±3.8 group was significantly higher than that of the middle tertile (8.4±4.0 and lower tertile (7.6±3.8 groups. In addition, FRS was highest in the IRD group (10.5±3.7. Multiple linear regression analysis demonstrated that HbA1c levels exhibited a significant positive correlation with FRS when adjusted for confounding variables in all subjects (β±standard error [SE], 0.018±0.002; R2, 0.131, women (β±SE, 0.023±0.003; R2, 0.170, and men (β±SE, 0.016±0.004; R2, 0.109.ConclusionHbA1c levels were positively correlated with FRS in older, apparently healthy nondiabetic Korean adults. We propose that HbA1c levels may reflect CVD risk in nondiabetic individuals.

Construction of Korean adult voxel phantoms for radiation dosimetry and their applications

Energy Technology Data Exchange (ETDEWEB)

Lee, Choon Sik

2002-08-15

Although contribution of the MIRD-type mathematical anthropomorphic phantoms to computational radiation dosimetry, especially in determining the effective dose to the exposed personnel, is very significant, there remain some questions on possible deviation in the resulting dosimetric quantities from the true values. This is particularly the case for those organ or tissues having complicated geometry difficult to model with simple geometrical body elements. As an alternative approach to resolve the problem, there have been efforts to use voxel phantoms, which can very precisely describe both the external shape and the internal organs by virtue of fast advances in medical imaging technology as well as in computing power. In this study, Korean adult male and female voxel phantoms were constructed by processing whole-body MR images of healthy volunteers who belong to middle group of Korean in height and weight. Organs and tissues on tomographic images were manually segmented and indexed using the graphic software PL-400 . Due to limited resolution of the raw MR images, voxels of rather large size, 2 mmx2 mmx8 mm for the woman and 2mmx2mmx10mm for the man, were used. The resulting male and female voxel phantoms were named KRMAN and KRWOMAN, respectively. To assess utility of the voxel phatoms, calculations were carried out with the Monte Carlo code MCNP4B for two illustrative problems. A program VOXELMAKER1.0 was developed to convert the voxel phantom data into MCNP geometry input format. In the first example, organ equivalent doses and effective doses were evaluated for phantoms in broad parallel photon fields of different energies and directions and were compared to corresponding values given in ICRP 74 which were derived with the MIRD-type phantoms. No significant deviations between MIRD and voxel phantoms were found in the effective doses. Significant differences up to around factor of 2, however, were observed in organ equivalent doses for some organs including

Findings from studies in Western countries showed that Mediterranean diet is inversely associated with metabolic syndrome, but little is known about this association in Asian countries. To evaluate the association between Mediterranean diet and metabolic syndrome in Korean population, this study was conducted. A total of 8387 adults 19-64 years of age from the Korea National Health and Nutrition Examination Survey 2012-2015 were assessed. A 112-item dish-based semiquantitative food frequency questionnaire was used to assess dietary intakes. Mediterranean diet was assessed by a modified Mediterranean diet score, which was based on the alternate Mediterranean diet score of Fung et al. Multivariable logistic regression models were used to calculate odds ratios (ORs) with 95% confidence intervals (CIs) adjusted for other dietary and lifestyle variables. Participants with 5-6 and 7 or higher modified Mediterranean diet scores had a lower prevalence of metabolic syndrome by 27% (OR = 0.73, 95% CI: 0.56-0.96) and 36% (OR = 0.64, 95% CI: 0.46-0.89; P-trend = 0.0031), compared with those with 2 or lower modified Mediterranean diet scores, respectively. Higher modified Mediterranean diet scores were associated with a lower prevalence of abdominal obesity and hypertriglyceridemia, which are components of metabolic syndrome CONCLUSIONS: Our findings suggest that diet rich in fruit, vegetables, whole grains, legumes, peanuts and fish is associated with a lower prevalence of metabolic syndrome in Korean adults.

Excessive Consumption of Green Tea as a Risk Factor for Periodontal Disease among Korean Adults

Directory of Open Access Journals (Sweden)

Kyungdo Han

2016-07-01

Full Text Available This study was performed to assess the relationship between the amount of green tea that is consumed and periodontitis. It is based on data obtained from the Korea National Health and Nutrition Examination Survey, conducted between 2008 and 2010. A community periodontal index equal to code 3 was defined as moderate periodontitis, and code 4 was defined as severe periodontitis (n = 16,726. Consumption of green tea less than one cup per day was associated with a decreased prevalence of periodontal disease among Korean adults. The association between the consumption of green tea and periodontal disease was independent of various potential confounding factors, such as age, sex, body mass index, smoking, drinking, exercise, metabolic syndrome, frequency of tooth brushing per day, use of secondary oral products, the number of dental examination per year, diabetes, hypertension, and white blood cell count. Adjusted odds ratio and 95% confidence interval of no consumption was 1.360 (1.156, 1.601 when participants with consumption of two times per week ≤ x < 7 times per week was considered as a reference. However, consumption of one or more cups per day increased the prevalence of moderate and severe periodontitis. In conclusion, excessive consumption of green tea may be considered as a risk factor for periodontal disease among Korean adults.

Previous studies have examined associations between sitting time and negative health outcomes and mental health. However, the relationship between overall sitting time and major depressive disorder (MDD) in South Korea has not been studied. This study examined the association between MDD and overall sitting time and physical activity in South Koreans. Data from the sixth Korean National Health and Nutrition Examination Survey (KNHANES), a cross-sectional, nationally representative survey, were analyzed. Total participants were 4145 in 2014. MDD was assessed using the Patient Health Questionnaire (PHQ-9). Participants' data regarding self-reported sitting time and physical activity were analyzed via multiple logistic regression. Results showed that people who sat for 8-10 h (OR: 1.56, 95% CI: 1.15-2.11) or more than 10 h (OR: 1.71, 95% CI: 1.23-2.39) had increased risk of MDD compared to those who sat for less than 5 h a day. Subgroup analysis showed that the strongest effect of reported sitting time on risk of MDD was found in men with lower levels of physical activity who sat for 8 to 10 h (OR: 3.04, 95% CI: 1.15-8.01) or more than 10 h (OR: 3.43, 95% CI: 1.26-9.35). Level of physical activity was not an independent predictor for MDD. Sitting for long periods was associated with greater risk of MDD in South Korean adults. Reducing sitting time in people with MDD could help to prevent associated physical health problems and may improve mental health.

Full Text Available BACKGROUND: Sex differences have been reported in the prognosis of certain cancers. In this study, we investigated whether Korean females display better survival rates compared with male patients for solid tumor sites. METHODS: We analyzed data from the Korean National Cancer Incidence Database from 599,288 adult patients diagnosed with solid cancers between 2005 and 2009. Patients were followed until December 2010. We applied a relative excess risk (RER model adjusting for year of follow-up, age at diagnosis, and stage at diagnosis. RESULTS: For all solid cancer sites combined, women displayed an 11% lower risk of death compared to men (RER 0.89; 95% CI 0.88-0.90 after adjusting for year of follow-up, age, stage, and case mix. Women showed significantly lower RERs for the following sites: head/neck, esophagus, small intestine, liver, nasal cavities, lung, bone/cartilages, melanoma of skin, soft tissue, brain and CNS, and thyroid. In contrast, women displayed a poorer prognosis than did men for colorectal, laryngeal, kidney and bladder cancer. However, the survival gaps between men and women narrowed by increase in age; female patients over 75 years of age displayed a 3% higher RER of death compared with males in this age group. CONCLUSIONS: Female cancer patients display an improved survival for the majority of solid tumor sites, even after adjustment for age and stage. Age at diagnosis was the major contributor to the women's survival advantage.

Full Text Available BackgroundLow levels of physical activity (PA are strongly associated with the development of metabolic syndrome (MetS and chronic diseases. However, few studies have examined this association in Koreans. The primary purpose of this study was to examine the associations between PA and MetS risks in Korean adults.MethodsA total of 1,016 Korean adults (494 males and 522 females participated in this study. PA levels were assessed using the International PA Questionnaire. MetS risk factors were determined using clinically established diagnostic criteria.ResultsCompared with the highest PA group, the group with the lowest level of PA was at greater risk of high triglyceride (TG in males (odds ratio [OR], 1.87; 95% confidence interval [CI], 1.07 to 3.24 and of hemoglobin A1c ≥5.5% in females (OR, 1.75; 95% CI, 1.00 to 3.04 after adjusting for age and body mass index. Compared with subjects who met the PA guidelines, those who did not meet the guidelines were more likely to have low high density lipoprotein cholesterol in both males (OR, 1.69; 95% CI, 1.11 to 2.58, and females (OR, 1.82; 95% CI, 1.20 to 2.77. Furthermore, those who did not meet the PA guidelines were at increased risk of high TG levels in males (OR, 1.69; 95% CI, 1.23 to 2.86 and abnormal fasting glucose (OR, 1.93; 95% CI, 1.17 to 3.20 and MetS (OR, 2.10; 95% CI, 1.15 to 3.84 in females.ConclusionIncreased levels of PA are significantly associated with a decreased risk of abnormal MetS components.

Thirty three frequently eaten items among meat and eggs were collected and pretreated. Selenium (Se) contents in the diet samples were analyzed using an instrumental neutron activation analysis (INAA). 100 g of beef contains 12.4-50.9 μg of Se; pork, 11.2-22.6 μg; chicken, 10.2-13.7 μg and eggs, 28.6-43.0 μg. Beef innards and chicken eggs contain the highest amounts of Se. This study reveals that Se intake of Korean adults are 28.7 μg/day in men and 27.6 μg/day in women from meat and eggs, which are over 1/2 of the Korean recommended Se intake. (author)

Molecular diagnosis of glycogen storage diseases (GSDs) is important to enable accurate diagnoses and make appropriate therapeutic plans. The aim of this study was to evaluate the PHKA2 mutation spectrum in Korean patients with GSD type IX. Thirteen Korean patients were tested for PHKA2 mutations using direct sequencing and a multiplex polymerase chain reaction method. A comprehensive review of the literature on previously reported PHKA2 mutations in other ethnic populations was conducted for comparison. Among 13 patients tested, six unrelated male patients with GSD IX aged 2 to 6 years at the first diagnostic work-up for hepatomegaly with elevated aspartate transaminase (AST) and alanine transaminase (ALT) were found to have PHKA2 mutations. These patients had different PHKA2 mutations: five were known mutations (c.537 + 5G > A, c.884G > A [p.Arg295His], c.3210_3212delGAG [p.Arg1072del], exon 8 deletion, and exons 27-33 deletion) and one was a novel mutation (exons 18-33 deletion). Notably, the most common type of mutation was gross deletion, in contrast to other ethnic populations in which the most common mutation type was sequence variant. This study expands our knowledge of the PHKA2 mutation spectrum of GSD IX. Considering the PHKA2 mutation spectrum in Korean patients with GSD IX, molecular diagnostic methods for deletions should be conducted in conjunction with direct sequence analysis to enable accurate molecular diagnosis of this disease in the Korean population.

Full Text Available Background: Facial emotion recognition (FER is impaired in individuals with frontotemporal dementia (FTD and Alzheimer’s disease (AD when compared to healthy older adults. Since deficits in emotion recognition are closely related to caregiver burden or social interactions, researchers have fundamental interest in FER performance in patients with dementia.Purpose: The purpose of this study was to identify the performance profiles of six facial emotions (i.e., fear, anger, disgust, sadness, surprise, and happiness and neutral faces measured among Korean healthy control (HCs, and those with mild cognitive impairment (MCI, AD, and FTD. Additionally, the neuroanatomical correlates of facial emotions were investigated.Methods: A total of 110 (33 HC, 32 MCI, 32 AD, 13 FTD older adult participants were recruited from two different medical centers in metropolitan areas of South Korea. These individuals underwent an FER test that was used to assess the recognition of emotions or absence of emotion (neutral in 35 facial stimuli. Repeated measures two-way analyses of variance were used to examine the distinct profiles of emotional recognition among the four groups. We also performed brain imaging and voxel-based morphometry (VBM on the participants to examine the associations between FER scores and gray matter volume.Results: The mean score of negative emotion recognition (i.e., fear, anger, disgust, and sadness clearly discriminated FTD participants from individuals with MCI and AD and HC [F(3,106 = 10.829, p < 0.001, η2 = 0.235], whereas the mean score of positive emotion recognition (i.e., surprise and happiness did not. A VBM analysis showed negative emotions were correlated with gray matter volume of anterior temporal regions, whereas positive emotions were related to gray matter volume of fronto-parietal regions.Conclusion: Impairment of negative FER in patients with FTD is cross-cultural.

Full Text Available Background. No previous study examined a disease modifying effect of APOE E4 status on the association between the urinary albumin-to-creatinine ratio (UACR and cognition. This study aimed to investigate whether APOE E4 modified the association in Korean adults. Methods. We performed a cross-sectional study in adults aged 45 to 74 who were living in Namwon City, Republic of Korea. Cognitive function was measured with the Korean version of modified Mini-Mental State Examination (K-mMMSE and cognitive impairment was defined as scores falling below the 25th percentile of the K-mMMSE according to age, sex, and educational attainments. Results. A total of 10,190 participants (4006 men and 6184 women were analyzed in the present study. Of these, 1698 subjects (16.7% were APOE E4 carriers. The UACR values were negatively associated with the K-mMMSE scores, even after adjusting for potential confounders including age, sex, education, and vascular risk factors. APOE E4 modified the association significantly, resulting in a steeper decline of cognitive function with the increase in UACR in E4 carriers (P for interaction = 0.021. Conclusion. Higher UACR values were significantly associated with cognitive dysfunction in the general Korean population, with cognition in APOE E4 carriers being more severely affected by increased UACR.

The study was undertaken to assess the ventricular system of the brain in normal Korean adults on the base of computed tomography. The computerized tomographic examinations of 334 Korean adults between ages of 15 to 50 years, performed at Seoul National University Hospital, were evaluated. The cerebro- or cerebello-ventricular ratio, between ventricular size and brain parenchyme width, has been known to be a reliable indicator of the ventricular size. This ratio was measured at the level of the lateral, third and fourth ventricles respectively. The shape of the quardigeminal and suprasellar cistern was analyzed. The results are as follows: 1. The cerebroventricular ratios of the lateral ventricle at the level of the widest bifrontal and bicaudate diameters were 0.30 ± 0.04 and 0.14 ± 0.02, respectively. The lateral ventricle was asymmetric in 12.6%, of which the left side was usually larger than the right. 2. There was correlation between the cerebroventricular ratio and age, i.e., with increase of age, the C-V ratio increased slightly. 3. The cerebroventricular ratio of the third ventricle was 0.03 ± 0.01. 4. The cerebroventricular ratio of the fourth ventricle in width and height was 0.14± 0.02 and 0.10 ± 0.03, respectively. The anteroposterior position index of the fourth ventricle was 0.42 ± 0.04. 5. The quadrigeminal cistern showed W-shape in 76.6% and U-shape in 23.4%. 6. The suprasellar cistern showed pentagonal shape in 61.1%, round in 28.4% and hexagonal in 10.5%. 7. There was no significant difference between male and female according to the above results

Sleep need differs between individuals, and so the same duration of sleep will lead to sleep insufficiency in some individuals but not others. The aim of this study was to determine the separate and combined associations of both sleep duration and unmet sleep need with excessive daytime sleepiness (EDS) in Korean adults. The participants comprised 2,769 Korean adults aged 19 years or older. They completed questionnaires about their sleep habits over the previous month. The question regarding sleep need was "How much sleep do you need to be at your best during the day?" Unmet sleep need was calculated as sleep need minus habitual sleep duration. Participants with a score of >10 on the Epworth Sleepiness Scale were considered to have EDS. The overall prevalence of EDS was 11.9%. Approximately one-third of the participants (31.9%) reported not getting at least 7 hours of sleep. An unmet sleep need of >0 hours was present in 30.2% of the participants. An adjusted multivariate logistic regression analysis revealed a significant excess risk of EDS in the groups with unmet sleep needs of ≥2 hours [odds ratio (OR), 1.80; 95% confidence interval (CI), 1.27-2.54] and 0.01-2 hours (OR, 1.42; 95% CI, 1.02-1.98). However, habitual sleep duration was not significantly related to EDS. EDS was found to be associated with unmet sleep need but not with habitual sleep duration when both factors were examined together. We suggest that individual unmet sleep need is more important than habitual sleep duration in terms of the relation to EDS.

The present study was conducted to assess the relationship between metabolic syndrome and systolic inter-arm blood pressure difference (sIAD) in Korean adults. This study included 410 adults (235 males, 175 females) who were over 30 years old and had undergone a health check from July to December in 2013. The incidence of high sIAD and metabolic syndrome were 23.4% and 23.2%, respectively. Key study results were as follows: First, the sIAD levels increased significantly with an increase in metabolic syndrome score (p<0.001), shown by sIAD levels after adjusted the variables that affect sIAD levels (age, gender, smoking, drinking, exercising, total cholesterol, and body mass index). These were 4.6±0.7 mmHg for metabolic syndrome score (MSS) 0; 5.8±0.5 mmHg for MSS 1; 6.2±0.6 mmHg for MSS 2, 9.2±0.8 mmHg for MSS 3; and 9.9±1.2 mmHg for MSS ≥4 (p<0.001). Second, the sIAD level of the metabolic syndrome group (9.3±0.7 mmHg) was significantly higher (p<0.001) than for the nonmetabolic syndrome group (5.7±0.3 mmHg). In conclusion, metabolic syndrome and an increased number of its components are associated with the sIAD levels in Korean adults.

The purpose of this study was to evaluate the relationships between the prevalence of depression and dental pain using a well characterised, nationally representative, population-based study. This study analysed data from the 2012 Korea National Health and Nutrition Examination Survey (n = 4886). Oral health status was assessed using the oral health questionnaire, and oral examination was performed by trained dentists. Depression was defined as the participant having been diagnosed as depression during the previous year. Logistic regression was applied to estimate adjusted odds ratios (AOR) and 95% confidence intervals (CI), controlling for a range of covariates. Results demonstrated that participants included in 'root canal treatment is necessary' showed higher prevalence of self-reported dental pain; in particular, participants with depression presented more dental pain than those without depression. After adjusting for sociodemographic factors, self-reported dental pain increased in participants with depression. The AOR (95% CI) for having self-reported dental pain was 1·58 (1·08-2·33) in dentists' diagnosis of no dental pain/depression group, 1·62 (1·32-1·98) in dentists' diagnosis of dental pain/no depression group and 2·84 (1·10-7·37) in dentists' diagnosis of dental pain/depression group. It was concluded that depression was associated with dental pain after adjustment for potential confounders in Korean adults. Thus, dentists should consider the possible presence of psychopathology when treating patients with dental pain. © 2015 John Wiley & Sons Ltd.

The aim of this study was to identify the attitudes of elderly Korean patients toward death and dying using Q-methodology to aid in the development of basic strategies for nursing care of elderly Koreans. Thirty participants at a university hospital sorted 40 selected Q-statements on a nine-point scale. Data analysis identified three types of attitudes toward death and dying in elderly patients in Korea: religion-dependent, science-adherent, and sardonic. Religion-dependent elders are highly dependent upon religion as evidenced by their reply that they would like to rely on God and a minister the most. Science-adherent elders have great affection for life and believe in modern medical advancements. The sardonic elders regard death as the dispensation of nature so there is no need to be afraid of death and dying. This study will contribute to the understanding that nurses and other health professionals have of the perceptions of elderly Koreans about death and dying. Also, the findings may provide the basis for the development of more appropriate strategies to improve death and dying education programs of health professionals.

Accumulated data suggests a positive effect of silicon on bone health; however, limited research exists on the silicon content of foods. To further the understanding of the relationship between dietary silicon intake and bone health, a food composition database of commonly consumed foods in Korea is required. For quantitative data on the intake levels of silicon, we analyzed the silicon content of 365 food items commonly consumed in Korea using inductively coupled plasma-atomic emission spectrometry following microwave-assisted digestion. To investigate the dietary silicon intake status and to examine the potential role of dietary silicon intake in the bone status of men, a total of 400 healthy Korean adult males aged 19-25 were observed for their diet intake and calcaneus bone density using the 24-h recall method and quantitative ultrasound, respectively. Clinical markers reflecting bone metabolism such as serum total alkaline phosphatase, N-mid osteocalcin, and type 1 collagen C-terminal telopeptide concentrations were also analyzed. Silicon intake of the subjects was estimated as 37.5 ± 22.2 mg/day. Major food sources of dietary silicon in the Korean male were cereal and cereal products (25.6 % of total silicon intake), vegetables (22.7 %), beverages and liquors (21.2 %), and milk and milk products (7.0 %). Silicon intake correlated positively with age, weight, energy intake, protein intake, calcium intake, and alcohol intake. After adjusted for age, weight, energy intake, protein intake, calcium intake, alcohol intake, smoking cigarettes, and regular exercise status, daily total silicon intake had no correlation with calcaneus bone density and the bone metabolism markers, but silicon intake from vegetables had a positive correlation with serum total alkaline phosphatase activity, a bone formation maker. These findings show the possible positive relationship between dietary silicon intake from vegetables and the bone formation of young adult males. Further

The patterns of renogram in patients with Korean hemorrhagic fever were evaluated with clinical course and renal hemodynamic changes in various clinical stages. The renal plasma flow was measured by hippuran blood clearance using 131 I-ortho-iodohippurate and hippuran renogram was analysed means of quantitative and qualitative methods in 26 patients of Korean hemorrhagic fever. The results obtained with this study were as follows;1) During the oliguric phase of Korean hemorrhagic fever, the renogram showed non-functioning (flat) or obstructive pattern. The group of patients with non-functioning pattern of renogram had more severe impairment of renal function and grave prognosis than the group with obstructive pattern of renogram. 2) During the diuretic phase, the renogram showed obstructive or dysfunction ar normal pattern, which was related with the recovery of renal function. Obstruction pattern of renogram was observed till the 2nd week of diuretic phase. Normal pattern of renogram began to appear by the 2nd week of diuretic phase. 3) During the convalescent phase of Korean hemorrhagic fever, 40% of patients showed dysfunction pattern of renogram, and the recovery of abnormal renogram in Korean hemorrhagic fever was more delayed than the recovery of clinical features and laboratory findings. 4) The renogram showed normal pattern 6 months after onset of Korean hemorrhagic fever in all cases. 5) There was significant correlationship between the pattern of renogram and the decrease of renal plasma flow in the patients with Korean hemorrhagic fever. The decrease of renal plasma flow was marked in the patients with non-functioning pattern of renogram and was least in the patients with dysfunction pattern of renogram. All above results suggested that the renogram reflects the effective renal plasma flow and degree of renal impairment, and the renogram may be one of the important indexes which could give us a more precise prognosis in Korean hemorrhagic fever.

Purpose To determine the spectrum and frequency of rhodopsin gene (RHO) mutations in Korean patients with retinitis pigmentosa (RP) and to characterize genotype–phenotype correlations in patients with mutations. Methods The RHO mutations were screened by direct sequencing, and mutation prevalence was measured in patients and controls. The impact of missense mutations to RP was predicted by segregation analysis, peptide sequence alignment, and in silico analysis. The severity of disease in patients with the missense mutations was compared by visual acuity, electroretinography, optical coherence tomography, and kinetic visual field testing. Results Five heterozygous mutations were identified in six of 302 probands with RP, including a novel mutation (c.893C>A, p.A298D) and four known mutations (c.50C>T, p.T17M; c.533A>G, p.Y178C; c.888G>T, p.K296N; and c.1040C>T, p.P347L). The allele frequency of missense mutations was measured in 114 ethnically matched controls. p.A298D, newly identified in a sporadic patient, had never been found in controls and was predicted to be pathogenic. Among the patients with the missense mutations, we observed the most severe phenotype in patients with p.P347L, less severe phenotypes in patients with p.Y178C or p.A298D, and a relatively moderate phenotype in a patient with p.T17M. Conclusions The results reveal the spectrum of RHO mutations in Korean RP patients and clinical features that vary according to mutations. Our findings will be useful for understanding these genetic spectra and the genotype–phenotype correlations and will therefore help with predicting disease prognosis and facilitating the development of gene therapy.

For radiological protection from exposure to ionizing radiation, in which a population-averaged dose evaluation is used, establishing a system of reference anatomical and physiological data for a specific population of interest is important. Some studies were done in the past to establish Korean reference data; however, the data provided the mass values only for a limited number of organs/tissues. In addition, the standing height and total body mass are based on 20-year-old data. In the present study, a new set of Korean reference anatomical values was established for use in the radiological protection of Korean workers and members of the public. The established Korean reference data provide the masses of 58 organs/tissues, including those needed to calculate the effective dose, which were derived by collecting and analyzing various scientific reports in the literature and data. In addition, the data provide not only standing height and total body mass, but also 131 additional anthropometric parameters; these values were derived from the most recent Korean national survey project, 7 th Size Korea. The characteristics of the data were also compared with several other population data, including the Asian and the International Commission on Radiological Protection (ICRP) reference data.

Blood lead and cadmium levels are more than twofold to fivefold higher in the Korean population compared to that of the USA. This may be related to the foods consumed. We examined which food categories are related to blood lead and cadmium levels in the Korean adult population using the 2008-2010 Korean National Health and Nutrition Examination Survey (n = 5504). High and moderate consumption of bread and crackers, potatoes, meat and meat products, milk and dairy products, and pizza and hamburger resulted in significantly lower odds ratios for blood lead levels than their low consumption. However, consumption of salted fish, white fish, green vegetables, white and yellow vegetables, coffee, and alcohol resulted in significantly higher odds ratios of blood lead and cadmium. In conclusion, the typical Asian diet based on rice, fish, vegetables, regular coffee, and alcoholic drinks may be associated with higher blood cadmium and lead levels. This study suggests that lead and cadmium contents should be monitored and controlled in agricultural products to reduce health risks from heavy metals.

Although it is known that epilepsy and spirituality are related, spirituality in epilepsy has received relatively little clinical and scientific attention. Therefore, we investigated which epilepsy-related factors are associated with high spirituality in Korean adults living with epilepsy. This cross-sectional study was conducted in two university hospitals in Korea. Spirituality was assessed using the 6-item Spirituality Self-Rating Scale (SSRS). The participants were categorized into high and low spirituality groups according to the median SSRS score. The presumptive seizure onset zone was determined based on the clinical semiology, electroencephalography, and magnetic resonance imaging findings. Of the 180 participants, 61.7% declared that they had a religious affiliation. The median SSRS score was 15 (interquartile range: 7, 22). The high spirituality subgroup consisted of 92 (51.1%) participants. In the univariate analyses, the high spirituality group was significantly associated with female sex (p<0.05), older age (p<0.01), longer epilepsy duration (p<0.05), polytherapy (p<0.05), complex partial seizure (p<0.05), levetiracetam or topiramate usage (p<0.05), and a right-lateralized seizure onset zone. The multiple logistic regression analysis identified right hemispheric lateralization as the only independent factor associated with high spirituality (odds ratio: 2.410, 95% confidence interval: 1.051-5.528, p<0.05). High spirituality may be associated with right hemispheric lateralization but not with the temporal localization of the seizure onset zone in Korean adults with epilepsy.

A roentgraphic cephalometric study was made on the soft and hard tissue profile of Korean adults. The subject consisted of 52 males and 54 females from 17 to 22 years of age and with normal occlusion and acceptable profile. Twenty one landmarks were plotted and two oriented lines named SnH line and SnV line were drawn on the tracings of all cephalograms. The means and the standard deviations from the subjects were calculated in each measuring category and the means were compared with those of male and female samples. The results were obtained as follow: 1. In depth and height, individual variations and sex differences of the lower facial profile were larger than the upper face. 2. The sex differences of upper facial profile were larger in height than depth. 3. The individual variations and sex differences of the top of nose were the smallest in all measuring points. 4. The thickness of the soft tissue of upper face and upper lip in male sample were larger than those of female, but the same matter were not found in mental region.

The prevalence of metabolic syndrome has been increasing in Korea and has been associated with dietary habits. The aim of our study was to identify the relationship between dietary patterns and the prevalence of metabolic syndrome. Using a validated food frequency questionnaire, we employed a cross-sectional design to assess the dietary intake of 1257 Korean adults aged 31 to 70 years. To determine the participants' dietary patterns, we considered 37 predefined food groups in principal components analysis. Metabolic syndrome was defined according to the National Cholesterol Education Program Adult Treatment Panel III. The abdominal obesity criterion was modified using Asian guidelines. Prevalence ratios and 95% confidence intervals for the metabolic syndrome were calculated across the quartiles of dietary pattern scores using log binomial regression models. The covariates used in the model were age, sex, total energy intake, tobacco intake, alcohol consumption, and physical activity. The prevalence of metabolic syndrome was 19.8% in men and 14.1% in women. The PCA identified three distinct dietary patterns: the 'traditional' pattern, the 'meat' pattern, and the 'snack' pattern. There was an association of increasing waist circumference and body mass index with increasing score in the meat dietary pattern. The multivariate-adjusted prevalence ratio of metabolic syndrome for the highest quartile of the meat pattern in comparison with the lowest quartile was 1.47 (95% CI: 1.00-2.15, p for trend = 0.016). A positive association between the prevalence of metabolic syndrome and the dietary pattern score was found only for men with the meat dietary pattern (2.15, 95% CI: 1.10-4.21, p for trend = 0.005). The traditional pattern and the snack pattern were not associated with an increased prevalence of metabolic syndrome. The meat dietary pattern was associated with a higher prevalence of metabolic syndrome in Korean male adults.

The use of cardiac magnetic resonance (CMR) imaging is increasing for the assessment of certain cardiovascular diseases, due to recent technical developments. CMR can give physicians information that cannot be found with other imaging modalities. However, there has been no guideline for the use of CMR in Korean people. Therefore, we have prepared a Korean guideline for the appropriate utilization of CMR to guide Korean physicians, imaging specialists, medical associates, and patients to improve the overall performances in medical system. By addressing CMR usage and creating these guidelines, we hope to contribute to the promotion of public health. This guideline is a joint report of the Korean Society of Cardiology and the Korean Society of Radiology.

Sarcopenia, or loss of muscle mass, occurs with aging and results in frailty, disability, cardiovascular disease, and insulin resistance. Recently, researchers have asserted that sarcopenia is not an inevitable process, but is a modifiable condition. Adequate sleep duration is also important to maintain good physical and mental health. Therefore, the aim of our study was to examine the association between sleep duration and sarcopenia in Korean adults. Data from 16,148 participants (7,158 men and 8,990 women) were analyzed from the 2008-2011 Korean National Health and Nutrition Examination Survey (KNHANES). We defined sarcopenia as one standard deviation below the sex-specific means of the appendicular skeletal muscle/height-squared values of a young reference group. Participants were categorized into 5 groups according to sleep duration. The odds ratios (OR) and 95% confidence intervals (95% CI) for sarcopenia according to sleep duration were calculated using multiple logistic regression analysis. The prevalence of sarcopenia was 14.3% in the total population (males 18.7%, females 9.7%). Compared to the 7 hours of sleep group, the OR (95% CI) for sarcopenia of the long sleep duration group (9 hours or more) was 1.589 (1.100-2.295) after controlling for confounding factors. From the results of subgroup analysis, high-risk groups for sarcopenia are as follows: 40-64 years old (OR = 1.868), normal body mass index (OR = 1.516), smoking (OR = 2.219), no regular exercise (OR = 1.506) in long sleepers. Long sleep duration (9 hours or longer) is independently associated with sarcopenia in Korean adults. © 2017 American Academy of Sleep Medicine

The triglyceride glucose (TyG) index has been considered a simple surrogate marker of insulin resistance. However, few studies have investigated the relationship between the TyG index and coronary artery calcification (CAC). Thus, we investigated the relationship between the TyG index and CAC in healthy Korean adults. In total, 4319 participants who underwent cardiac computed tomography (CT) in a health promotion center were enrolled. Anthropometric profiles and multiple cardiovascular risk factors were measured. The TyG index was calculated as ln [fasting triglycerides (mg/dL) × fasting glucose (mg/dL)/2], and the insulin resistance index of homeostasis model assessment (HOMA-IR) was estimated. The CAC was measured using multidetector CT, and CAC presence was defined as an Agatston score of >0. All subjects were stratified into four groups based on their TyG indices. Significant differences were observed in cardiovascular parameters among the groups, and the prevalence of CAC significantly increased with increasing TyG index. In the logistic regression analysis after adjustment for multiple risk factors, the odds ratio for the prevalence of CAC, when comparing the highest and lowest quartiles of the TyG index was 1.95 (95% CI 1.23-3.11; P for trend = 0.01); the odds ratio for the prevalence of CAC, when comparing the highest and lowest quartiles of HOMA-IR was 1.64 (95% CI 1.12-2.40; P for trend = 0.04). In the receiver operating characteristics analysis, the TyG index was superior to HOMA-IR in predicting CAC. The TyG index is more independently associated with the presence of coronary artery atherosclerosis than is HOMA-IR in healthy Korean adults.

The purposes of this study were to identify the relationships among perceived parental bonding, illness perception, and anxiety and to determine the influences of perceived parental bonding and illness perception on anxiety in adult patients with congenital heart diseases. In this study a descriptive correlational design with survey method was utilized. The participants were 143 adult patients with congenital heart disease being cared for in the cardiology out-patient clinic of A medical center. Data were collected using the Parental Bonding Instrument, Illness Perception Questionnaire Revised Scale, and Cardiac Anxiety Questionnaire Scale. Data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Pearson correlation analysis, and hierarchial regression analyses. There showed significant positive relationships of anxiety with maternal overprotection, consequences, and personal control respectively. Among predictors, maternal overprotection (β=.45), consequence (β=.26), and personal control (β=-.03) had statistically significant influence on anxiety. Nursing interventions to decrease maternal overprotection and negative consequence, and to enhance personal control are essential to decrease the anxiety of adult patients with congenital heart diseases. © 2017 Korean Society of Nursing Science

Age-related eye disease is often considered part of natural aging. Lack of awareness of eye conditions can result in missed treatment. We investigated the rates of awareness of cataract and age-related macular degeneration, the most common age-related eye-diseases, and the associated factors among elderly Koreans. We identified 7,403 study subjects (≥40 years old) with cataract or age-related macular degeneration based on ophthalmic examination results during the 5th Korean National Health and Nutrition Examination Survey conducted between 2010 and 2012. We assessed whether patients were aware of their eye condition based on a previous diagnosis by a physician. The average awareness rate over the 3-year study period was 23.69% in subjects with cataract and 1.45% in subjects with age-related macular degeneration. Logistic regression analysis showed that patients with cataract were more likely to recognize their condition if they had myopia (odds ratio, 2.08), hyperopia (odds ratio, 1.33), family history of eye disease (odds ratio, 1.44), or a past eye examination (odds ratio, 4.07-29.10). The presence of diabetes mellitus was also a significant predictor of patient awareness of cataract (odds ratio, 1.88). Poor patient recognition of eye disease among the Korean elderly highlights the seriousness of this potential public health problem in our aging society. Pre-existing eye-related conditions and diabetes were significant predictors of awareness; therefore, patients in frequent contact with their doctors have a greater chance of detecting eye disease. © 2017 The Korean Ophthalmological Society

2001-08-15

A Korean female voxel phantom was constructed to overcome the limitations of anatomical description of the existing MRD-type mathematical anthropomorphic phantom and the example dose calculations were carried out for the radiation protection by using it. This whole body voxel phantom was based on the MRIs of the Korean adult female who falls into the reference Korean female group. The cross sectional human pictures from VHP of NLM was adopted for the modification and compensation of the missing MRIs of Korean adult female that include legs below upper thighs. From the gastrointestinal and respiratory organ which make obscure organ edges because of their continuing motion, the general anatomical knowledge were applied for the segmentation process. The Korean female whole body voxel phantom named in HYWOMAN is composed of 1,392,400 voxels that have width x length x height of 4mm x 4mm x 8mm for each with the total of 20 organs identified. With MDNP4B code the tissue equivalent doses were calculated for the four different energies of 0.4, 0.8, 2 and 8 MeV broad parallel gamma beam in AP, PA, LLAT and RLAT directions. The tissue equivalent doses were compared with those of ORNL adult female phantom under the same irradiation conditions. Despite of the small organ differences there could be found the considerable differences in tissue equivalent doses for some organs including thyroid, esophagus, kidneys and spleen. The cause of these discrepancies were proved to be the position of the organs in the phantom and the consequent shielding effects. With the methodology of this study, Korean reference male and female age-grouped voxel phantoms can be constructed and consequently the dosimetry system for typical Korean people is to be established.

The purpose of this study was to translate the Spiritual Perspective Scale (SPS) and Self-transcendence Scale (STS) into Korean and test the psychometric properties of the instruments with Korean elders. A cross-sectional survey design was used to implement the three stages of the study. Stage I consisted of translating and reviewing the scales by six experts. In Stage II, equivalence was tested by comparing the responses between the Korean and English versions among 71 bilingual adults. Stage III established the psychometric properties of the Korean versions SPS-K and STS-K among 154 Korean elders. Cronbach's alpha of the SPS-K and the STS-K .97, and .85 respectively with Korean elders. Factor analysis showed that the SPS-K had one factor; the STS-K had four factors with one factor clearly representing self-transcendence as theorized. Both scales showed good reliability and validity for the translated Korean versions. However, continued study of the construct validity of the STS-K is needed. Study findings indicate that the SPS-K and the STS-K could be useful for nurses and geriatric researchers to assess a broadly defined spirituality, and to conduct research on spirituality and health among Korean elders. Use of these scales within a theory-based study may contribute to further knowledge about the role of spirituality in the health and well-being of Korean people facing health crises.

Full Text Available The present study was conducted to assess the gender difference in the relationship between serum ferritin and 25-hydroxyvitamin D [25(OHD] in Korean adults.A total of 5,147 adults (2,162 men, 1,563 premenopausal women, and 1,422 postmenopausal women aged ≥ 20 years from the Korean National Health and Nutrition Examination Survey (KNHANES data (2012 were analyzed. A covariance test adjusted for covariates was performed for serum ferritin levels in relation to vitamin D status (vitamin D deficiency, 25(OHD < 10.0 ng/mL; vitamin D insufficiency, 25(OHD ≥ 10.0, < 20.0 ng/mL; vitamin D sufficiency, 25(OHD ≥ 20.0 ng/mL.The key study results were as follows: First, in men, in terms of serum ferritin levels by serum 25(OHD level after adjusting for age, smoking, alcohol drinking, regular exercise, SBP, DBP, WM. TC, TGs, HDL-C, FPG, Hb, Hct, MCV, and Fe, serum ferritin levels were inversely increased with the increasing of serum 25(OHD level (P = 0.012. Second, in premenopausal women, after adjusting for related variables, serum ferritin levels were increased with the increasing of serum 25(OHD level (P = 0.003. Third, in postmenopausal women, after adjusting for related variables, serum ferritin levels were not significantly increased with the increasing of serum 25(OHD level (P = 0.456.Serum 25(OHD level was inversely associated with the serum ferritin levels in men, but was positively associated with the serum ferritin levels in premenopausal women, and was not associated with the serum ferritin levels in postmenopausal women.

The purpose of the study was to examine the reliability and validity of the Adherence to Refills and Medications Scale-Korean (ARMS-K) among Korean adults with type 2 diabetes. The Korean translated ARMS-K was back-translated to ensure translation equivalency. A cross-sectional survey was used to evaluate the psychometric properties with exploratory factor analysis for validity and Cronbach's alpha coefficients for reliability. The factor analysis of construct validity identified 3 dimensions of the ARMS-K, explaining 54.7% of the total variance. The internal consistency reliability for the total instrument was acceptable with a Cronbach's alpha of .801. There was good correlation between the ARMS-K and 8-item Morisky Medication Adherence Scale-Korean version (r = -0.698), indicating that these scales measure theoretically related constructs as evidence of convergent validity. As evidence of known groups validity, there was a significant association between the ARMS-K score and glycemic control (P = .048), indicating that the good glycemic controlled group was more likely to have a higher rate of adherence to refills and medications than the poor glycemic controlled group. These results support the cross-cultural applicability of the concepts underlying the ARMS-K. The ARMS-K can be used not only to assess adherence to refills and medications in Koreans with diabetes but also to examine the potential role of adherence to refills and medications in enhanced glycemic control of people with diabetes in a variety of clinical settings. © 2016 The Author(s).

This paper investigates the trend in height among adult Korean orphans who were adopted in early life into affluent Western nations. Final heights of 148 females were analyzed based on a Korean government survey conducted in 2008. Height of the orphans was descriptively compared against final heights of South and North Koreans. Furthermore, statistical determinants of orphan height were investigated in multivariate regressions. Mean height of Korean orphans was 160.44 cm (SD 5.89), which was higher than that of South Koreans at 158.83 cm (SD 5.01). Both Korean orphans and South Koreans were taller than North Koreans at 155.30 cm (SD 4.94). However, height of Korean orphans stagnated at around 160-161 cm while those of North and South Koreans improved over time. In the regression analysis, the socioeconomic status of the adoptive family was statistically significant in all models, while dummies for the adoptive nations and age at adoption were insignificant. This study shows that the mean final height of women experiencing extreme environmental improvements in early-life is capped at 160-161 cm, tentatively suggesting that social stress factors in the host nation or early-life factors in the birth nation might have offset some of the environmental enrichment effects achieved through intercountry adoption.

Few studies have reported the factors associated with intention to quit smoking among Korean adult smokers. This study aimed to examine sociodemographic characteristics, smoking-related beliefs, and smoking-restriction variables associated with intention to quit smoking among Korean adult smokers. We used data from the International Tobacco Control Korea Survey, which was conducted from November through December 2005 by using random-digit dialing and computer-assisted telephone interviewing of male and female smokers aged 19 years or older in 16 metropolitan areas and provinces of Korea. We performed univariate analysis and multiple logistic regression analysis to identify predictors of intention to quit. A total of 995 respondents were included in the final analysis. Of those, 74.9% (n = 745) intended to quit smoking. In univariate analyses, smokers with an intention to quit were younger, smoked fewer cigarettes per day, had a higher annual income, were more educated, were more likely to have a religious affiliation, drank less alcohol per week, were less likely to have self-exempting beliefs, and were more likely to have self-efficacy beliefs regarding quitting, to believe that smoking had damaged their health, and to report that smoking was never allowed anywhere in their home. In multiple logistic regression analysis, higher education level, having a religious affiliation, and a higher self-efficacy regarding quitting were significantly associated with intention to quit. Sociodemographic factors, smoking-related beliefs, and smoking restrictions at home were associated with intention to quit smoking among Korean adults.

The National Oral Health Screening Program (NOHSP) is a general population-based program in Korea. The objective of this study was to assess the association between participation in the NOHSP and dental visit for periapical abscess (PA) and advanced periodontal disease (APD) among Korean adults. Data were obtained for subjects from the National Health Insurance database. The authors conducted a retrospective cohort study of 9358 randomly selected subjects who were between 40 and 64 years old in 2002. The outcomes of dental visit for PA or APD from the years 2003 to 2007 were compared between the screening and nonscreening groups. The nonscreening group had 19% higher risk of PA and 15% higher risk of APD. This study suggests that the NOHSP may decrease the risk of dental visit because of PA and APD by preventing the progress of lesion to the advanced stage among Korean adults.

Management options for patients with immune thrombocytopenia (ITP) have evolved substantially over the past decades. The American Society of Hematology published a treatment guideline for clinicians referring to the management of ITP in 2011. This evidence-based practice guideline for ITP enables the appropriate treatment of a larger proportion of patients and the maintenance of normal platelet counts. Korean authority operates a unified mandatory national health insurance system. Even though we have a uniform standard guideline enforced by insurance reimbursement, there are several unsolved issues in real practice in ITP treatment. To optimize the management of Korean ITP patients, the Korean Society of Hematology Aplastic Anemia Working Party (KSHAAWP) reviewed the consensus and the Korean data on the clinical practices of ITP therapy. Here, we report a Korean expert recommendation guide for the management of ITP.

Religiosity can be important in the everyday life of persons with epilepsy (PWE). How PWE live with religiosity can be influenced by their cultural background. We determined whether religiosity is associated with anxiety, depressive symptoms, and well-being in Korean adults with epilepsy. This multicenter cross-sectional study was conducted in the outpatient clinics of five university hospitals in Korea. Religiosity was assessed using the five-item Duke University Religion Index (DUREL). The WHO-Five Well-Being Index (WHO-5) and Hospital Anxiety Depression Scale were used. The participants were categorized into three subgroups bounded by the 33rd and 66th percentiles of their DUREL scores. Of a total of 226 participants, 61.1% declared that they had religious affiliation. The median DUREL score was 11 (interquartile ranges 6, 18). All three subscales of the DUREL were significantly related to WHO-5 (p<0.01). Non-organizational religious activities such as prayer and meditation were also inversely related to anxiety (p<0.05) and depressive symptoms (p<0.01). After controlling for confounding variables, anxiety and depressive symptoms were more extensive in the low religiosity subgroup than in the high or no religiosity subgroup (p<0.01) and well-being was higher in the high or low religiosity subgroup than in the no religiosity subgroup (p<0.05). Religiosity is significantly associated with anxiety, depressive symptoms, and well-being in Korean adults with epilepsy. Copyright © 2017 Elsevier Inc. All rights reserved.

A roentgenological study on the position of the stomach in Korean adults, and the radiological evaluation of gastric acid secretion

The position and form of the stomach vary depending upon the position and habit of the body, spatial conditions of the abdominal cavity, phase of respiration, level of the liver and diaphragm. There has been much speculation about the criteria and significance of gastroptosis. Some regard gastroptosis as a manifestation of asthenic habit, while others claim that this entity is a generalized symptom complex. However, it appears that many clinicians in this country prefer to ascribe the gastric symptoms subtly to gastroptosis in the patients in whom no organic lesions can be detectable on x-ray study and physical examination of the gastrointestinal tract. Furthermore, they say that level of the stomach is considerably lower in position and the incidence of gastroptosis is much higher in Koreans than in western peoples or in Japanese. Employing a roentgenological study the author made observations on the level and form of the stomach in 100 healthy Korean adults and on the interrelationships of the stomach, level of the other abdominal viscera and gastric emptying time in 46 symptomatic patients with no demonstrable organic lesions. The interrelationship between the acidity of gastric secretion and the mucosal pattern of the stomach and duodenum was also evaluated in 92 patients in whom no demonstrable organic lesion was found. The results obtained are summarized as follows: 1. The lower pole of the stomach was lying below Jacob's line in 18% of 73 healthy men under 40 years of age and in 44% of the asymptomatic individuals over 40 years, while in symptomatic group it was lying below Jacob's line in 35% of 65 men under 40 years of age and in 56% of 71 patients over 40 years. 2. The incisura angularis of the stomach was observed lying below Jacob's line in 7.5% of the symptomatic groups. On the contrary, the incisura angularis was located above the level of the iliac crest in all of the healthy group. 3. The stomach of Korean adults was slightly higher in position than

Objectives The purpose of this study was to investigate whether blood mercury concentrations associated with the presence of dry eye symptoms in a nationally representative Korean population. Methods Population-based prospective cross-sectional study using the heavy metal data set of the 2010–2012 Korean National Health and Nutrition Examination Survey (KNHANES). A total of 4761 adult Koreans were the eligible population in this study. Of the 7162 survey participants, 2401 were excluded because they were mercury levels were measured on the day the participants completed a questionnaire regarding the presence of dry eye symptoms (persistent dryness or eye irritation). The population was divided into low and high groups by median level (4.26 and 2.89 µg/L for males and females, respectively). Results Self-reported dry eye symptoms were present in 13.0% of the cohort. Participants with dry eye symptoms were significantly more likely to have blood mercury levels exceeding the median than those without dry eye symptoms (45.7% vs 51.7%, p=0.021). Logistic regression analysis showed that, after adjusting for age, gender, education, total household income, smoking status, heavy alcohol use, sleep time, perceived stress status, total cholesterol levels and atopy history, dry eye symptoms were significantly associated with blood mercury levels that exceeded the median (reference: lower mercury group; OR, 1.324; 95% CI 1.059 to 1.655; pmercury levels were associated with dry eye symptoms in a nationally representative Korean population.

Despite a relatively high rate of suicide associated with cancer, this issue has not been explored in Korean patients. This study investigates the prevalence and factors related to 'the desire for hastened death' (DHD) in Korean cancer patients. A cross-sectional survey using standardised measures, including the Schedule of Attitudes toward Hastened Death and the Hospital Anxiety and Depression Scale, was performed with 131 patients with different types of cancer. 13.7% of the participants experienced moderate DHD (Schedule of Attitudes toward Hastened Death scores 5-9) and 1.7% experienced high DHD (≥10). Socio-demographic and disease-associated factors of the DHD included age, overall health and shortness of breath. The majority of psychosocial variables such as sadness, distress, 'helplessness/hopelessness' and 'anxious preoccupation' had a moderate association with DHD. Patients with a clinically significant level of anxiety or depression reported higher levels of DHD. Other significant correlates included 'meaning/peace', a sense of burdening family, dignity impairment and suicidal thoughts after diagnosis. Helplessness/hopelessness and anxiety were the strongest predictors of DHD in multivariate analysis. In view of significant role of helplessness/hopelessness and anxiety in the DHD of cancer patients, careful monitoring and management of these factors should be an integral part of cancer care to reduce the occurrence of DHD. © 2010 Blackwell Publishing Ltd.

To investigate abnormalities in blood electrolyte levels during severe hypoglycemia in Korean patients with type 2 diabetes mellitus (T2DM) in a clinical setting. Blood electrolyte levels in adult T2DM patients during severe hypoglycemia were collected from January 1, 2008 to December 31, 2012. Patients who maintained normal serum creatinine and blood urea nitrogen levels were utilized in the study. Severe hypoglycemia was defined as a condition requiring medical assistance, such as administering carbohydrates when serum glucose levels less than 70 mg/dL were observed, in conjunction with other symptoms of hypoglycemia. A total of 1,068 patients who visited the emergency room with severe hypoglycemia were screened, of which 219 patients were included in this study. The incidence of abnormal levels for any electrolyte was 47%. Hypokalemia (type of electrolyte disturbance observed at 21.9%. A decrease in serum potassium levels was associated with decreases in blood glucose levels (r = 0.151, p = 0.025). During severe hypoglycemia, median blood glucose levels, incidence of tachycardia (> 100 beats per minute) and severe hypertension (≥ 180/120 mmHg) were 30 mg/dL (range, 14 to 62) and 35 mg/dL (range, 10 to 69; p = 0.04), 18.8% and 7.2% (p = 0.02), and 20.8% and 10.2% (p = 0.05) in the hypokalemia and normokalemia groups, respectively. During severe hypoglycemia, hypokalemia occurred in 21.9% of T2DM patients and was associated with tachycardia and severe hypertension. Therefore, the results suggest that severe hypoglycemia may increase cardiovascular events in T2DM.

The purpose of this study was to develop a tool to evaluate patient safety culture in nursing homes and to test its validity and reliability. A preliminary tool was developed through interviews with focus group, content validity tests, and a pilot study. A nationwide survey was conducted from February to April, 2011, using self-report questionnaires. Participants were 982 employees in nursing homes. Data were analyzed using Cronbach's alpha, item analysis, factor analysis, and multitrait/multi-Item analysis. From the results of the analysis, 27 final items were selected from 49 items on the preliminary tool. Items with low correlation with total scale were excluded. The 4 factors sorted by factor analysis contributed 63.4% of the variance in the total scale. The factors were labeled as leadership, organizational system, working attitude, management practice. Cronbach's alpha for internal consistency was .95 and the range for the 4 factors was from .86 to .93. The results of this study indicate that the Korean Patient Safety Culture Scale has reliability and validity and is suitable for evaluation of patient safety culture in Korean nursing homes.

We aimed to evaluate the association of periodontitis with the development of early atherosclerotic vascular disease in Korean adults. In this cross-sectional study, a total of 1343 adults aged over 40 years were recruited from a community-based cohort of Yangpyeong county, Korea, during the period 2010-2014. Only dentate individuals were included in the study. Subclinical atherosclerosis (SA) was defined as carotid intima-media thickness (cIMT)≥0.754 mm, as assessed bilaterally by B-mode ultrasound. Peripheral arterial disease (PAD) was defined as ankle-brachial index (ABI)≤1.0, as measured by Doppler. History of periodontitis was assessed by measuring the radiographic alveolar bone loss (RABL) on a digital dental panorama and was classified into three groups: normal, moderate and severe periodontitis (≥2 non-adjacent interproximal sites with RABL≥4 mm and 6 mm, respectively). The associations of periodontitis with SA and PAD were evaluated by multivariable logistic regression analysis and analysis of covariance, adjusted for age, sex, education level, tooth loss, smoking, drinking, exercise, obesity, triglycerides, HDL, LDL, hs-CRP, diabetes and hypertension. Stratified analyses were performed to identify specific risk groups. After controlling for confounders, severe periodontitis was associated with SA [adjusted odds ratio (aOR) = 1.55; 95% confidence interval (CI): 1.07-2.24] and PAD (aOR = 2.03; 95% CI: 1.05-3.93). These associations were highlighted in never-smokers. For increasing severity of periodontitis, the adjusted mean cIMT increased (p = 0.011) while that of ABI decreased (p = 0.033). Our data showed that periodontitis is a substantially important risk factor for atherosclerotic vascular disease among Korean adults. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Abstract Although the relationship between diabetes and periodontitis is well established, the association between periodontitis and prediabetes has been investigated less extensively. Furthermore, there has been little research on the prevalence of periodontitis among individuals with prediabetes and diabetes as well as in the overall population using nationally representative data. Among 12,406 adults (≥19 years’ old) who participated in the 2012–2013 Korea National Health and Nutrition Examination Survey, a total of 9977 subjects completed oral and laboratory examinations and were included in this analysis. Periodontitis was defined as a community periodontal index score of ≥3 according to the World Health Organization criteria. The fasting plasma glucose level was categorized into the following 5 groups: normal fasting glucose (NFG) 1 (periodontitis among the Korean adult population was 24.8% (23.3–26.4%) (weight n = 8,455,952/34,086,014). The unadjusted weighted prevalences of periodontitis were 16.7%, 22.8%, 29.6%, 40.7%, and 46.7% in the NFG 1, NFG 2, IFG 1, IFG 2, and diabetes groups, respectively (P periodontitis increased to 29.7% in the IFG 2 group (P = 0.045) and 32.5% in the diabetes group (P periodontitis with the above-mentioned variables as covariates were 1.42 (95% confidence interval [CI] 1.14–1.77, P = 0.002) in the diabetes group and 1.33 (95% CI 1.01–1.75, P = 0.044) in the IFG 2 group, respectively, compared with the NFG1 group. In conclusion, a higher range of IFG levels as well as diabetes, were positively associated with chronic periodontitis in a representative sample of Korean adults. This study suggests that individuals with a higher range of IFG levels before diabetes are at risk of periodontitis, and may benefit from dental screening. PMID:27057854

Full Text Available It has been suggested that a greater dairy consumption, particularly of milk, may have contributed in lowering the prevalence of metabolic syndrome (MetS. A cross-sectional analysis was conducted to examine the association between milk consumption and MetS, and its components among Korean adults aged 40–69. A total of 130,420 subjects (43,682 men and 86,738 women from the Health Examinees Study were selected for the final analysis. Milk consumption was estimated using a validated 106-item food frequency questionnaire. MetS was defined using the National Cholesterol Education Program, Adult Treatment Panel III (NCEP III. Logistic regression analyses were performed to calculate the odds ratios (ORs and 95% confidence intervals (CIs between milk consumption and MetS after adjusting for potential confounders. In this study, the average milk consumption was 77.9 g/day, with the overall prevalence of MetS being 26.1% (29.1% in men and 24.6% in women. We found that the prevalence of the MetS was significantly lower in subjects with higher milk consumption (p < 0.0001. Adjusted OR for MetS was significantly lower in the highest milk consumption category (≥1 serving/day among men; ≥2 serving/day among women than those in the lowest milk consumption category (OR: 0.92 95%CI: 0.86–0.99, p trend = 0.0160 in men; OR: 0.68, 95%CI: 0.60–0.76, p trend < 0.0001 in women. Overall, higher milk consumption was inversely associated with the MetS components: elevated waist circumference, elevated triglyceride, and reduced high-density lipoprotein cholesterol (HDL-C (all p trend < 0.05. This study concludes that higher milk consumption is associated with the lower odds of MetS in Korean adults.

The purpose of this study is to develop and validate the Korean Health Literacy Instrument, which measures the capacity to understand and use health-related information and make informed health decisions in Korean adults. In Phase 1, 33 initial items were generated to measure functional, interactive, and critical health literacy with prose, document, and numeracy tasks. These items included content from health promotion, disease management, and health navigation contexts. Content validity assessment was conducted by an expert panel, and 11 items were excluded. In Phase 2, the 22 remaining items were administered to a convenience sample of 292 adults from community and clinical settings. Exploratory factor and item difficulty and discrimination analyses were conducted and four items with low discrimination were deleted. In Phase 3, the remaining 18 items were administered to a convenience sample of 315 adults 40-64 years of age from community and clinical settings. A confirmatory factor analysis was performed to test the construct validity of the instrument. The Korean Health Literacy Instrument has a range of 0 to 18. The mean score in our validation study was 11.98. The instrument exhibited an internal consistency reliability coefficient of 0.82, and a test-retest reliability of 0.89. The instrument is suitable for screening individuals who have limited health literacy skills. Future studies are needed to further define the psychometric properties and predictive validity of the Korean Health Literacy Instrument.

Two conversion tables between the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) have recently been established for Parkinson's disease (PD). This study aimed to validate them in Korean patients with PD and to evaluate whether they could be influenced by educational level. A total of 391 patients with PD who undertook both the Korean MMSE and the Korean MoCA during the same session were retrospectively assessed. The mean, median, and root mean squared error (RMSE) of the difference between the true and converted MMSE scores and the intraclass correlation coefficient (ICC) were calculated according to educational level (6 or fewer years, 7-12 years, or 13 or more years). Both conversions had a median value of 0, with a small mean and RMSE of differences, and a high correlation between the true and converted MMSE scores. In the classification according to educational level, all groups had roughly similar values of the median, mean, RMSE, and ICC both within and between the conversions. Our findings suggest that both MMSE-MoCA conversion tables are useful instruments for transforming MoCA scores into converted MMSE scores in Korean patients with PD, regardless of educational level. These will greatly enhance the utility of the existing cognitive data from the Korean PD population in clinical and research settings.

Full Text Available Objectives. The aims of this study were to perform a cultural translation of the DMSES and evaluate the psychometric properties of the translated scale in a Korean population with type 2 diabetics. Methods. This study was conducted in patients with diabetes recruited from university hospitals. The first stage of this study involved translating the DMSES into Korean using a forward- and backward-translation technique. The content validity was assessed by an expert group. In the second stage, the psychometric properties of the Korean version of the DMSES (K-DMSES were evaluated. Results. The content validity of the K-DMSES was satisfactory. Sixteen-items clustered into four-subscales were extracted by exploratory factor analysis, and supported by confirmatory factor analysis. The construct validity of the K-DMSES with the Summary of Diabetes Self-Care Activities scale was satisfactory (r=0.50, P<0.001. The Cronbach’s alpha and intraclass correlation coefficient were 0.92 and 0.85 (P<0.001; 95% CI=0.75–0.91, respectively, which indicate excellent internal consistency reliability and test-retest reliability. Conclusions. The K-DMSES is a brief instrument that has demonstrated good psychometric properties. It is therefore feasible to use in practice, and is ready for use in clinical research involving Korean patients with type 2 diabetes.

Full Text Available BackgroundWe investigated the association of coronary artery calcium score (CACS with body composition and insulin resistance in apparently healthy Korean adults.MethodsNine hundred forty-five participants (mean age, 48.9 years; 628 men in a medical check-up program were selected for analysis. Body composition was assessed by bioelectrical impedance analysis (BIA. Insulin resistance was evaluated using the homeostasis model assessment of insulin resistance (HOMA-IR. The CACS was assessed by multidetector computed tomography.ResultsOne hundred forty-six subjects (15.4% showed coronary artery calcification and 148 subjects (15.7% had metabolic syndrome. CACS showed a significant positive correlation with age, fasting glucose level, waist circumference (WC, blood pressure, hemoglobin A1c, HOMA-IR, and waist-hip ratio (WHR assessed by BIA. CACS had a negative correlation with high density lipoprotein cholesterol (HDL-C. Subjects with high CACS showed significantly higher mean WHRs and lower mean values for lean body mass compared with subjects without coronary artery calcification. In logistic regression analyses with coronary artery calcification as the dependent variable, the highest quartile of WHR showed a 3.125-fold increased odds ratio for coronary artery calcification compared with the lowest quartile after adjustment for confounding variables. When receiver operating characteristics analyses were performed with coronary artery calcification as the result variable, WHR showed the largest area under the curve (AUC value among other variables except for age and WC in women (AUC=0.696 for WHR, 0.790 for age, and 0.719 for WC in women.ConclusionIn our study population of apparently healthy Korean adults, WHR was the most significant predictor for coronary artery calcification among other confounding factors, suggesting that it may have implication as a marker for early atherosclerosis.

Epilepsy is a concealable stigmatizing condition. We investigated the factors predicting disclosure management behavior in Korean adults with newly diagnosed epilepsy. This longitudinal multicenter study included Korean adults with newly diagnosed epilepsy. Using statistical analyses, we determined at the end of a 1-year follow-up whether Disclosure Management Scale (DMS) scores were predicted by demographic, clinical, and psychosocial variables, including felt stigma, stress coping style, personality traits, social support, and experienced discrimination from society. Of a total of 121 participants, 69% reported that they often or sometimes kept their diagnosis a secret from others and rarely or never talked to others about their epilepsy. The average DMS score was 5.8 (SD=2.9, range 0-11). In univariate analyses, DMS scores were significantly associated with an emotion-focused coping style (r=0.320, pepilepsy often or sometimes keep their epilepsy a secret. Emotion-focused coping is the most important predictor of concealment of epilepsy diagnosis at the end of a 1-year follow-up, although social support and episodes of experienced discrimination are also associated with disclosure management strategies.

Our study aims to analyze prognosis after implantable cardioverter-defibrillator (ICD) implantation in Korean patients with Brugada syndrome (BrS). This was a retrospective study of BrS patients implanted with an ICD at one of four centers in Korea between January 1998 and April 2012. Sixty-nine patients (68 males, 1 female) were implanted with an ICD based on aborted cardiac arrest (n=38, 55%), history of syncope (n=17, 25%), or induced ventricular tachyarrhythmia on electrophysiologic study in asymptomatic patients (n=14, 20%). A family history of sudden cardiac death and a spontaneous type 1 electrocardiography (ECG) were noted in 13 patients (19%) and 44 patients (64%), respectively. During a mean follow-up of 59±46 months, 4.6±5.5 appropriate shocks were delivered in 19 patients (28%). Fourteen patients (20%) experienced 5.2±8.0 inappropriate shocks caused by supraventricular arrhythmia, lead failure, or abnormal sensing. Six patients were admitted for cardiac causes during follow-up, but no cardiac deaths occurred. An episode of aborted cardiac arrest was a significant predictor of appropriate shock, and the composite of cardiac events in the Cox proportional hazard model [hazard ratio (95% confidence interval) was 11.34 (1.31-97.94) and 4.78 (1.41-16.22), respectively]. However, a spontaneous type 1 ECG was not a predictor of cardiac events. Appropriate shock (28%) and inappropriate shock (20%) were noted during a mean follow-up of 59±46 months in Korean BrS patients implanted with an ICD. An episode of aborted cardiac arrest was the most powerful predictor of cardiac events.

The purpose of this study was to monitor the use of health-related quality of life (HRQOL) instruments in Korean studies of patients with diabetes. Of 86 Korean studies initially identified, 17 studies met the inclusion criteria. For each study, a description of the instrument and its psychometric properties were monitored by the Instrument Review Criteria of the Scientific Advisory Committee. These criteria include conceptual definition, attributes, taxonomy, reliability, validity, responsiveness, administrative mode, and language adaptations. Five generic and one diabetes specific type questionnaires were identified from the 17 studies. Of those studies, conceptual definitions with the attributes of multi-dimension and subjectiveness were provided for 11 studies (71%). In the analysis of conceptual taxonomy, only 6 studies were classified as HRQOL, while other studies were done as QOL or health status. In monitoring of psychometric properties, reliability, validity, and responsiveness were reported for 88.2%, 64.7%, and 29.4%, respectively. One generic instrument was developed with a Korean population, while the other instruments were developed for Western countries. However, language adaptations were performed for only a few of the instruments. The psychometric properties including responsiveness of most instruments warrants further research, and the development of diabetes-specific HRQOL measurements should be sought to facilitate intervention outcomes across Korean studies of patients with diabetes.

Mutation or common intronic variants in cardiac ion channel genes have been suggested to be associated with sudden cardiac death caused by idiopathic ventricular tachyarrhythmia. This study aimed to find mutations in cardiac ion channel genes of Korean sudden cardiac arrest patients with structurally normal heart and to verify association between common genetic variation in cardiac ion channel and sudden cardiac arrest by idiopathic ventricular tachyarrhythmia in Koreans. Study participants were Korean survivors of sudden cardiac arrest caused by idiopathic ventricular tachycardia or fibrillation. All coding exons of the SCN5A, KCNQ1, and KCNH2 genes were analyzed by Sanger sequencing. Fifteen survivors of sudden cardiac arrest were included. Three male patients had mutations in SCN5A gene and none in KCNQ1 and KCNH2 genes. Intronic variant (rs2283222) in KCNQ1 gene showed significant association with sudden cardiac arrest (OR 4.05). Four male sudden cardiac arrest survivors had intronic variant (rs11720524) in SCN5A gene. None of female survivors of sudden cardiac arrest had SCN5A gene mutations despite similar frequencies of intronic variants between males and females in 55 normal controls. Common intronic variant in KCNQ1 gene is associated with sudden cardiac arrest caused by idiopathic ventricular tachyarrhythmia in Koreans.

A study was performed to investigate the size of pharyngeal cavity and sexual differences between Korean adult mal e and female by introducing linear analysis of the lateral cephalogram. The radiograms were composed of 46 adult male aged 24.64 and 52 adult female aged 22.74 respectively. In order to study and measure the pharyngeal area, the following skeletal landmarks were selected: S,N,A,Ptm, B,H,H', M ,S-N, FH and CV, and the angle CV-FH was measured to provide a factor for correction of error resulting from improper he ad positioning of subjects, especially in the relative positions of A and H, while radiography. All points to be measured were projected at right angles to the Frankfort plane. For the purpose of measuring the anteroposterior dimensions of pharyngeal cavity the distances were measured in A-Ptm, A-S, S-Ptm and CV-H, and vertical measurements were made in SN-A, SN-PNS, SN-H' and M-H. The obtained results were as follows: 1. The pharyngeal cavity is broader in the vertical than in the anteroposterior diameter in both sex and the maximum sexual differences were showed in the distances between SN and H', and minimal sexual differences in the distances between S and Ptm. 2. In general, the measurements of male were larger than those of female in the anteroposterior dimensions of pharyngea l cavity, but the distances between A and S, between CV and H showed significant sexual differences when evaluated statistically. 3. All of the measurements were larger in male than in female in vertical dimensions of pharyngeal cavity, and there were statistical significances of sexual differences in all variables.

The Peripheral Artery Questionnaire (PAQ), as developed in US English, is a validated scale to evaluate the health status of patients with peripheral artery disease (PAD). The aim of this study was to translate the PAQ into Korean and to evaluate its reliability and validity. A multi-step process of forward-translation, reconciliation, consultation with the developer, back-translation and proofreading was conducted. The test-retest reliability was evaluated at a 2-week interval using the intra-class correlation coefficient (ICC). The validity was assessed by identifying associations between Korean PAQ (KPAQ) scores and Korean Health Assessment Questionnaire (KHAQ) scores. A total of 100 PAD patients were enrolled: 63 without and 37 with severe claudication. The reliability of the KPAQ was adequate, with an ICC of 0.71. There were strong correlations between KPAQ's subscales. Cronbach's alpha for the summary score was 0.94, indicating good internal consistency and congruence with the original US version. The validity was supported by a significant correlation between the total KHAQ score and KPAQ physical function, stability, symptom, social limitation and quality of life scores (r = -0.24 to -0.90; p < 0.001) as well as between the KHAQ walking subscale and the KPAQ physical function score (r = -0.55, p < 0.001). Our results indicate that the KPAQ is a reliable, valid instrument to evaluate the health status of Korean patients with PAD.

The demand for autonomy in medical decision making is increasing among Korean people, but it is not well known why some people prefer autonomy in decision making but others do not. The aim of this study was to determine the extent to which Korean adults wished to exercise autonomy in the process of decision making regarding end-of-life treatment and to determine whether economic issues and family functioning, in particular, were associated with preferences for participation in decision making in Korean people. This study was a cross-sectional correlational study using a survey. Data were collected using structured questionnaires from 354 patients or their families who visited ambulatory departments at two general hospitals in South Korea, recruited by the proportionate quota sampling method. Data analysis was performed using multinomial logistic regression analyses. The study was approved by the hospitals' directors and the ethics committee of Kyungpook National University Hospital. Written informed consent was given by all participants. A majority of Korean people wanted to make autonomous decisions regarding treatment at the end of life. Preferences for autonomous decision making regarding end-of-life treatment, rather than relying on family, showed a significant increase in association with poor family functioning and low income. Results of this study suggested the necessity for development of alternatives to a dominant traditional "family-centered" approach in Korean people, in order to enhance end-of-life decision making for people who wish to take an active role in the decision-making process. Healthcare providers need to examine not only patients' preferred decision-making style but also any reasons for their choice, in particular, family conflict and financial burden. © The Author(s) 2014.

This post hoc analysis evaluated treatment effects, safety, and pharmacokinetics of enzalutamide in Korean patients in the phase 3, double-blind, placebo-controlled PREVAIL trial. Asymptomatic or mildly symptomatic chemotherapy-naive men with metastatic castration-resistant prostate cancer that progressed on androgen deprivation therapy received 160 mg/d oral enzalutamide or placebo (1:1) until death or discontinuation due to radiographic progression or skeletal-related event and initiation of subsequent therapy. Coprimary end points were centrally assessed radiographic progression-free survival (rPFS) and overall survival (OS). Secondary end points included investigator-assessed rPFS, time to initiation of chemotherapy, time to prostate-specific antigen (PSA) progression, PSA response (≥50% decline), and time to skeletal-related event. Of 1,717 total patients, 78 patients were enrolled in Korea (enzalutamide, n=40; placebo, n=38). Hazard ratios (95% confidence interval) for enzalutamide versus placebo were 0.23 (0.02-2.24) for centrally assessed rPFS, 0.77 (0.28-2.15) for OS, 0.21 (0.08-0.51) for time to chemotherapy, and 0.31 (0.17-0.56) for time to PSA progression. A PSA response was observed in 70.0% of enzalutamide-treated and 10.5% of placebo-treated Korean patients. Adverse events of grade ≥3 occurred in 33% of enzalutamide-treated and 11% of placebo-treated Korean patients, with median treatment durations of 13.0 and 5.1 months, respectively. At 13 weeks, the plasma concentration of enzalutamide plus N-desmethyl enzalutamide was similar in Korean and non-Korean patients (geometric mean ratio, 1.04; 90% confidence interval, 0.97-1.10). In Korean patients, treatment effects and safety of enzalutamide were consistent with those observed in the overall PREVAIL study population (ClinicalTrials.gov Identifier: NCT01212991).

Background Few studies have reported the factors associated with intention to quit smoking among Korean adult smokers. This study aimed to examine sociodemographic characteristics, smoking-related beliefs, and smoking-restriction variables associated with intention to quit smoking among Korean adult smokers. Methods We used data from the International Tobacco Control Korea Survey, which was conducted from November through December 2005 by using random-digit dialing and computer-assisted telephone interviewing of male and female smokers aged 19 years or older in 16 metropolitan areas and provinces of Korea. We performed univariate analysis and multiple logistic regression analysis to identify predictors of intention to quit. Results A total of 995 respondents were included in the final analysis. Of those, 74.9% (n = 745) intended to quit smoking. In univariate analyses, smokers with an intention to quit were younger, smoked fewer cigarettes per day, had a higher annual income, were more educated, were more likely to have a religious affiliation, drank less alcohol per week, were less likely to have self-exempting beliefs, and were more likely to have self-efficacy beliefs regarding quitting, to believe that smoking had damaged their health, and to report that smoking was never allowed anywhere in their home. In multiple logistic regression analysis, higher education level, having a religious affiliation, and a higher self-efficacy regarding quitting were significantly associated with intention to quit. Conclusions Sociodemographic factors, smoking-related beliefs, and smoking restrictions at home were associated with intention to quit smoking among Korean adults. PMID:22186157

There is a need for simple risk scores that identify individuals at high risk for metabolic syndrome (MetS). Therefore, this study was performed to develop and validate a self-assessment score for MetS risk in non-obese Korean adults. Data from the fourth Korea National Health and Nutrition Examination Survey (KNHANES IV), 2007-2009 were used to develop a MetS risk score. We included a total of 5,508 non-obese participants aged 19-64 years who were free of a self-reported diagnosis of diabetes, hyperlipidemia, hypertension, stroke, angina, or cancer. Multivariable logistic regression model coefficients were used to assign each variable category a score. The validity of the score was assessed in an independent population survey performed in 2010 and 2011, KNHANES V (n=3,892). Age, BMI, physical activity, smoking, alcohol consumption, dairy consumption, dietary habit of eating less salty and food insecurity were selected as categorical variables. The MetS risk score value varied from 0 to 13, and a cut-point MetS risk score of >=7 was selected based on the highest Youden index. The cut-point provided a sensitivity of 81%, specificity of 61%, positive predictive value of 14%, and negative predictive value of 98%, with an area under the curve (AUC) of 0.78. Consistent results were obtained in the validation data sets. This simple risk score may be used to identify individuals at high risk for MetS without laboratory tests among non-obese Korean adults. Further studies are needed to verify the usefulness and feasibility of this score in various settings.

Background The association between sarcopenia and cardiovascular disease (CVD) in elderly people has not been adequately assessed. The aim of this study was to investigate whether CVD is more prevalent in subjects with sarcopenia independent of other well-established cardiovascular risk factors in older Korean adults. Method This study utilized the representative Korean population data from the Korea National Health and Nutrition Examination Survey (KNHANES) which was conducted in 2009. Subjects older than 65 years of age with appendicular skeletal muscle mass (ASM) determined by dual energy X-ray absorptiometry were selected. The prevalence of sarcopenia in the older Korean adults was investigated, and it was determined whether sarcopenia is associated with CVD independent of other well-known risk factors. Results 1,578 subjects aged 65 years and older with the data for ASM were selected, and the overall prevalence of sarcopenia was 30.3% in men and 29.3% in women. Most of the risk factors for CVD such as age, waist circumference, body mass index, fasting plasma glucose and total cholesterol showed significant negative correlations with the ratio between appendicular skeletal muscle mass and body weight. Multiple logistic regression analysis demonstrated that sarcopenia was associated with CVD independent of other well-documented risk factors, renal function and medications (OR, 1.768; 95% CI, 1.075–2.909, P = 0.025). Conclusions Sarcopenia was associated with the presence of CVD independent of other cardiovascular risk factors after adjusting renal function and medications. PMID:23533671

Full Text Available Purpose Psychometric properties of the overactive bladder questionnaire (OAB-q were recently examined. However, since the cross-cultural adaptation of a non-English version of the OAB-q has never been demonstrated, we evaluated the psychometric properties of a Korean version of the OAB-q in a Korean population with OAB. Methods A prospective cohort study involving 116 women with 58 OAB and 58 control subjects was performed and convergent validity was assessed. Total and subscale OAB-q scores of the control and OAB groups were compared to their sensitivity to score changes before and after administering anti-cholinergic medication for 12 weeks. Short form 36 and King's health questionnaire (KHQ were also used for comparison or correlation. Results Assessment of face validity showed that the Korean version of the OAB-q was reasonable with OAB-q subscale scores being significantly different between the control and patient groups. Significant correlation (range, -0.29 to -0.81 was found between the OAB-q scores and KHQ results for the OAB patients. Cronbach's alpha coefficients (range, 0.77 to 0.95 indicated excellent internal consistency and test-retest analysis involving 35 OAB patients showed that each questions as well as subscale scores were reproducible. Each score of OAB-q also showed statistically significant sensitivity to changes following anti-muscarinic treatment for OAB (n=27, P<0.001 except for social, P=0.059. Conclusions The Korean version of the OAB-q is a valid and reliable instrument to measure outcomes in Korean patients with OAB.

Although previous studies have established a close relationship between caloric intake and metabolic syndrome, there is limited research exploring the impact of meal frequency adjusted by caloric intake on metabolic syndrome (MetS). To evaluate the association of meal frequency and MetS after adjusting for confounding factors including caloric intake in Korean men and women. We analyzed the national representative data of a total 12,389 adults (5171 men, 7218 women) from the Korean National Health and Nutrition Examination Survey (KNHANES) 2010-2012. Subjects were categorized as eating 3 meals/day (MF3) or 2 or fewer meals/day (MF ≤ 2). Daily caloric intake was calculated using CAN-Pro 4.0 (The Korean Nutrition Society, Seoul, Korea). The prevalence of components of MetS differed significantly according to meal frequency in both men and women. In an unadjusted analysis, the prevalence of MetS in women was significantly higher in the MF3 group than the MF ≤ 2 group (27.5% vs. 17.8%, P  meal frequency did not affect the risk of metabolic syndrome in women after adjusting for confounding factors including caloric intake (OR = 1.09, 95%, CI = 0.90-1.31). This study suggests that lower meal frequency adjusted for caloric intake, physical activity, age, smoking, alcohol, income, and education may be associated with increased risk of MetS in Korean men.

Previous studies showed inconsistent results concerning the relationship between chronic smoking and blood pressure. Most of the studies involved self-reported smoking status. This study was performed to evaluate the association of urinary cotinine or self-reported smoking status with hypertension and blood pressure in Korean adults. Among individuals enrolled in the Kangbuk Samsung Health Study and Kangbuk Samsung Cohort Study, 167,868 participants (men, 55.7%; age, 37.5 ± 6.9 years) between 2011 and 2013 who had urinary cotinine measurements were included. Individuals with urinary cotinine levels ≥50 ng/mL were defined as cotinine-verified current smokers. The prevalence of hypertension and cotinine-verified current smokers in the overall population was 6.8% and 22.7%, respectively (10.0% in men and 2.8% in women for hypertension: 37.7% in men and 3.9% in women for cotinine-verified current smokers). In a multivariate regression analysis adjusted for age, sex, body mass index, waist circumference, alcohol drinking, vigorous exercise, and diabetes, cotinine-verified current smoking was associated with lower prevalence of hypertension compared with cotinine-verified never smoking (OR[95% CI], 0.79 [0.75, 0.84]). Log-transformed cotinine levels and unobserved smoking were negatively associated with hypertension, respectively (0.96 [0.96, 0.97] and 0.55 [0.39, 0.79]). In a multivariate linear regression analysis, the cotinine-verified current smoking was inversely associated with systolic and diastolic blood pressure (BP) (regression coefficient[95% CI], -1.23[-1.39, -1.07] for systolic BP and -0.71 [-0.84, -0.58] for diastolic BP). In subgroup analyses according to sex, the inverse associations between cotinine-verified current smoking and hypertension were observed only in men. This large observational study showed that cotinine-verified current smoking and unobserved smoking were inversely associated with hypertension in Korean adults, especially only in

This study aimed to develop a Korean version of the Type D Personality Scale-14 (DS14) and evaluate the psychiatric symptomatology of Korean cardiac patients with Type D personality. Healthy control (n = 954), patients with a coronary heart disease (n = 111) and patients with hypertension and no heart disease (n = 292) were recruited. All three groups completed DS14, the Eysenck Personality Questionnaire (EPQ), the state subscale of Spielberger State and Trait Anxiety Inventory (STAI-S), the Center for Epidemiologic Studies Short Depression Scale (CESD), and the General Health Questionnaire (GHQ). The Korean DS14 was internally consistent and stable over time. 27% of the subjects were classified as Type D. Type D individuals had significantly higher mean scores on the STAI-S, CESD, and GHQ compared to non-Type D subjects in each group. The Korean DS14 was a valid and reliable tool for identifying Type D personality. The general population and cardiovascular patients with Type D personality showed higher rate of depression, anxiety and psychological distress regarding their health. Therefore, identifying Type D personality is important in clinical research and practice in chronic medical disorders, especially cardiovascular disease, in Korea.

The Scientific Report of the Dietary Guidelines Advisory Committee (2015) concluded that restriction of dietary cholesterol is unnecessary in most adults for the prevention of cardiovascular disease. We aimed to assess the risk for subclinical atherosclerosis according to coronary artery calcium score (CACS), based on dietary cholesterol intake in apparently healthy Korean adults. This was a cross-sectional study performed in 30,068 participants (mean age 40.8 years; 84.5% men) in a health screening program in Korea. The data were collected from 2001 to 2013 and analyzed in 2015. Total energy intake and dietary cholesterol intake were assessed with a food frequency questionnaire. The participants were stratified according to quartile of dietary cholesterol intake. CACS was measured by multi-detector computed tomography. Lipid profiles were measured, and the participants were divided into 6 groups according to low-density lipoprotein cholesterol (LDL-C) level: 0. Dietary cholesterol intake did not correlate with mean value of serum LDL-C level. For both genders, the odds ratio for coronary artery calcification was not significantly greater with greater amounts of dietary cholesterol (as assessed by quartile). The risk for coronary artery calcification was not higher in subjects with LDL-C 70-129 mg/dL compared with those with LDL-C < 70 mg/dL; however, the risk was significantly greater in subjects with LDL-C ≥ 130 mg/dL compared with those with LDL-C < 70 mg/dL. Dietary cholesterol intake did not have an association with LDL-C level or with risk for coronary artery calcification in apparently healthy Korean adults. The results have to be translated with consideration of limitation of population-based studies. Copyright © 2017 National Lipid Association. Published by Elsevier Inc. All rights reserved.

Objective Two conversion tables between the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) have recently been established for Parkinson’s disease (PD). This study aimed to validate them in Korean patients with PD and to evaluate whether they could be influenced by educational level. Methods A total of 391 patients with PD who undertook both the Korean MMSE and the Korean MoCA during the same session were retrospectively assessed. The mean, median, and root mean squared error (RMSE) of the difference between the true and converted MMSE scores and the intraclass correlation coefficient (ICC) were calculated according to educational level (6 or fewer years, 7–12 years, or 13 or more years). Results Both conversions had a median value of 0, with a small mean and RMSE of differences, and a high correlation between the true and converted MMSE scores. In the classification according to educational level, all groups had roughly similar values of the median, mean, RMSE, and ICC both within and between the conversions. Conclusion Our findings suggest that both MMSE-MoCA conversion tables are useful instruments for transforming MoCA scores into converted MMSE scores in Korean patients with PD, regardless of educational level. These will greatly enhance the utility of the existing cognitive data from the Korean PD population in clinical and research settings. PMID:29316782

However, there are few reports on the association between serum cystatin C and bone mineral density (BMD, especially in the Asian population. We evaluated the association between cystatin C levels and BMD of the spine and hip in Korean adults.Methods: A cross-sectional study was performed in 865 Korean adults (325 men and 540 women who participated in a comprehensive medical examination program and underwent bone densitometry. Renal function was assessed by the estimated glomerular filtration rate (eGFR, which was calculated using an equation based on creatinine (eGFRcre and cystatin C (eGFRcys.Results: The serum cystatin C level was negatively correlated with different types of BMD, including the lowest lumbar, total lumbar, femoral neck, and total femur BMD, in women, but not in men. Higher cystatin C levels were associated with a higher prevalence of osteoporosis in women (odds ratio [OR], 3.68; 95% confidence interval [CI], 1.69–8.03; P=0.001, but not in men (OR, 0.85; 95% CI, 0.30–2.38; P=0.761. However, this association was attenuated in the multivariable model adjusted for age, body mass index, serum 25-hydroxyvitamin D3, and creatinine (OR, 1.01; 95% CI, 0.38–2.71 in women. In addition, the eGFRcys showed a stronger positive correlation with BMD than the eGFRcre.Conclusion: Our findings suggest that serum cystatin C levels might help identify women with osteoporosis

Lactose-free milk (LFM) is available for nutrient supply for those with lactose intolerance (LI). However, there are no consistent results of the efficacy of LFM in LI subjects. We aimed to examine the changes of gastrointestinal (GI) symptoms and hydrogen breath test (HBT) values after ingestion of lactose contained milk (LCM) vs. LFM. From May 2015 to September 2015, thirty-five healthy adults with history of LCM-induced GI symptoms were recruited at a tertiary hospital. For the diagnosis of LI, HBT with LCM 550 mL (lactose 25 g) was performed every 20 minutes for 3 hours. The test was defined as "positive" when H2 peak exceeded 20 ppm above baseline values (ΔH2>20 ppm). When the subjects are diagnosed as LI, the second HBT using LFM 550 mL (lactose 0 g) was performed 7 days later. Subjects were asked to complete a questionnaire about the occurrence and severity of GI symptoms. Among a total of 35 subjects, 31 were diagnosed with LI at first visit, and their LCM-related symptoms were abdominal pain (98.6%), borborygmus (96.8%), diarrhea (90.3%), and flatus (87.1%). The ΔH2 value in subjects taking LCM (103.7±66.3ppm) significantly decreased to 6.3±4.9 ppm after ingesting LFM (p<0.0001). There were also significant reduction in total symptom scores and the severity of each symptom when LCM was changed to LFM (p<0.0001). This is the first report that LFM reduce LCM-related GI symptoms and H2 production in Korean adults. LFM can be an effective alternative for LCM in adults with LI.

Recently, the number of people interested in health in South Korea has increased, and the rate of dietary supplement use is rising. Researchers have hypothesized that the rate of practicing healthy habits is higher among those who use dietary supplements than those who do not. Therefore, this study aimed to discover the association between taking dietary supplements and practicing various healthy habits in the Korean, adult population. The sample included 15,789 adults over 19 years old who participated in the fifth Korea National Health and Nutrition Examination Survey. The user group was defined as those taking dietary supplements for more than 2 weeks during the previous year or once during the past month. Measures for the seven healthy habits were based on those included in the Alameda study and were analyzed accounting for the complex sampling design. The rate of taking dietary supplements was significantly higher in women, middle aged participants, urban residents, those with a higher income, those with a higher education level, and nonsmokers as well as among women with a moderate subjective health status, women who limited their alcohol content, and women with dyslipidemia. In the adjusted analysis, the rate of performing three of the 'Alameda 7' habits-eating breakfast regularly, restricting snacking, and limiting drinking-was higher in the female dietary supplement user group than in the other groups. Women practiced more healthy habits and had a higher dietary supplement intake rate than men. We found that taking dietary supplements in Korean adults is highly associated with demographic and social factors. Taking dietary supplements had a relationship with dietary habits, and there was no significant association between dietary supplement and other healthy habits. Thus in the health clinic, we suggest that taking dietary supplements complements a patient's healthy habits, with the exception of dietary habits, for health promotion.

This study aimed to evaluate an association between smoking, smoking cessation, and periodontal disease in Korean adults. The data were collected from 8,336 participants, aged between 20 and 64 years, who participated in the fifth Korea National Health and Nutrition Examination (2010 and 2012). Smoking status was assessed using self-administered questionnaires. Periodontal disease was defined as a community periodontal index ≥3 points. Logistic regression analysis was used to evaluate an association between smoking, smoking cessation, and periodontal disease after adjusting for age, sex, education, monthly income, diabetes, obesity, alcohol intake, and frequency of tooth brushing. The risk of periodontal disease was higher among current smokers (odds ratio [OR], 1.49; 95% confidence interval [CI], 1.21-1.83) than never smokers. Among current smokers, the risk of periodontal disease was increased in smokers of ≥10 cigarettes/d, ≥20 years duration, and >10 pack-years compared with never smokers (Pperiodontal disease after 10 years since cessation declined to 0.56 (95% CI, 0.42-0.75) compared with current smokers and was indistinguishable statistically from never smokers. Periodontal disease is significantly associated with smoking status in Korean adults.

Full Text Available BACKGROUND: There is a proposed link between dietary zinc intake and atherosclerosis, but this relationship remains unclear. Phytate may contribute to this relationship by influencing zinc bioavailability. OBJECTIVE: The aim of this study is to examine the relationship between zinc bioavailability and subclinical atherosclerosis in healthy Korean adults. MATERIALS AND METHODS: The present cross-sectional analysis used baseline data from the Korean multi-Rural Communities Cohort Study (MRCohort, which is a part of The Korean Genome Epidemiology Study (KoGES. A total of 5,532 subjects (2,116 men and 3,416 women aged 40 years and older were recruited from rural communities in South Korea between 2005 and 2010. Phytate:zinc molar ratio, estimated from a food-based food frequency questionnaire (FFQ of 106 food items, was used to determine zinc bioavailability, and carotid intima media thickness (cIMT and pulse wave velocity (PWV were measured to calculate the subclinical atherosclerotic index. RESULTS: We found that phytate:zinc molar ratio is positively related to cIMT in men. A higher phytate:zinc molar ratio was significantly related to an increased risk of atherosclerosis in men, defined as the 80(th percentile value of cIMT (5(th vs. 1(st quintile, OR = 2.11, 95% CI 1.42-3.15, P for trend = 0.0009, and especially in elderly men (5(th vs. 1(st quintile, OR = 2.58, 95% CI 1.52-4.37, P for trend = 0.0021. We found a positive relationship between phytate:zinc molar ratio and atherosclerosis risk among women aged 65 years or younger. Phytate:zinc molar ratio was not found to be related to PWV. CONCLUSIONS: Lower zinc bioavailability may be related to higher atherosclerosis risk.

The purpose of this study was to investigate whether blood mercury concentrations associated with the presence of dry eye symptoms in a nationally representative Korean population. Population-based prospective cross-sectional study using the heavy metal data set of the 2010-2012 Korean National Health and Nutrition Examination Survey (KNHANES). A total of 4761 adult Koreans were the eligible population in this study. Of the 7162 survey participants, 2401 were excluded because they were eye surgery. Blood mercury levels were measured on the day the participants completed a questionnaire regarding the presence of dry eye symptoms (persistent dryness or eye irritation). The population was divided into low and high groups by median level (4.26 and 2.89 µg/L for males and females, respectively). Self-reported dry eye symptoms were present in 13.0% of the cohort. Participants with dry eye symptoms were significantly more likely to have blood mercury levels exceeding the median than those without dry eye symptoms (45.7% vs 51.7%, p=0.021). Logistic regression analysis showed that, after adjusting for age, gender, education, total household income, smoking status, heavy alcohol use, sleep time, perceived stress status, total cholesterol levels and atopy history, dry eye symptoms were significantly associated with blood mercury levels that exceeded the median (reference: lower mercury group; OR, 1.324; 95% CI 1.059 to 1.655; pdry eye symptoms in a nationally representative Korean population.

To investigate the effects of hippotherapy for adult patients with brain disorders. Eight chronic brain disorder patients (7 males, mean age 42.4±16.6 years) were recruited. The mean duration from injury was 7.9±7.7 years. The diagnoses were stroke (n=5), traumatic brain disorder (n=2), and cerebral palsy (n=1). Hippotherapy sessions were conducted twice a week for eight consecutive weeks in an indoor riding arena. Each hippotherapy session lasted 30 minutes. All participants were evaluated by the Berg balance scale, Tinetti Performance-Oriented Mobility Assessment, 10 Meter Walking Test, Functional Ambulatory Category, Korean Beck Depression Inventory, and Hamilton Depression Rating Scale. We performed baseline assessments twice just before starting hippotherapy. We also assessed the participants immediately after hippotherapy and at eight weeks after hippotherapy. All participants showed no difference in balance, gait function, and emotion between the two baseline assessments before hippotherapy. During the eight-week hippotherapy program, all participants showed neither adverse effects nor any accidents; all had good compliance. After hippotherapy, there were significant improvements in balance and gait speed in comparison with the baseline assessment (phippotherapy. However, there was no significant difference in emotion after hippotherapy. We could observe hippotherapy to be a safe and effective alternative therapy for adult patients with brain disorders in improving balance and gait function. Further future studies are warranted to delineate the benefits of hippotherapy on chronic stroke patients.

We used community-based participatory research (CBPR) to explore barriers to healthcare access and utilization and identify potentially effective intervention strategies to increase access among members of the Korean community in North Carolina (NC). Our CBPR partnership conducted 8 focus groups with 63 adult Korean immigrants in northwest NC and 15 individual in-depth interviews and conducted an empowerment-based community forum. We identified 20 themes that we organized into four domains, including practical barriers to health care, negative perceptions about care, contingencies for care, and provider misconceptions about local needs. Forum attendees identified four strategies to improve Korean community health. Despite the implementation of the Patient Protection and Affordable Care Act (ACA), many Korean community members will continue to remain uninsured, and among those who obtain insurance, many barriers will remain. It is imperative to ensure the health of this highly neglected and vulnerable community. Potential strategies include the development of (1) low-literacy materials to educate members of the Korean community about how to access healthcare services, (2) lay health advisor programs to support navigation of service access and utilization, (3) church-based programming, and (4) provider education to reduce misconceptions about Korean community needs.

The purposes of this study were to investigate the level and distribution of job satisfaction and to explore work environment factors associated with job satisfaction of South Korean dentists. A stratified systematic random sample of 1029 dentists was selected from the 10 357 registered dentists in the Korean Dental Association. They were surveyed via a self-administered mail questionnaire. Job satisfaction was measured by a modified version of the Dentist Satisfaction Survey. The response rate was 62.2%. The mean score of overall job satisfaction among South Korean dentists was 3.2 out of 5. In terms of work environment factors, the most satisfying aspect was patient relations (3.7) and the least satisfying aspect was personal time (2.8). Multiple regression analysis identified a model including patient relations, perception of income, personal time, staff, and specialty training that accounted for 35% of variation in overall job satisfaction. The majority of the variance was explained by patient relations. This study suggests that patient relations, perception of income, personal time, staff, and specialty training are important work environment factors for job satisfaction among South Korean dentists. The findings of this study will be helpful to policy makers to design plans to increase the level of job satisfaction among South Korean dentists.

The aim of this research is to estimate lifetime costs and health consequences for Korean adult women who were exposed to secondhand smoke (SHS) at home. A Markov model was developed to project the lifetime healthcare costs and health outcomes of a hypothetical cohort of Korean women who are 40 years old and were married to current smokers. The Korean epidemiological data were used to reflect the natural history of SHS-exposed and non-exposed women. The direct healthcare costs (in 2014 US dollars) and quality-adjusted life years (QALYs) were annually discounted at 5% to reflect time preference. The time horizon of the analysis was lifetime and the cycle length was 1 year. Deterministic and probabilistic sensitivity analyses were conducted. In the absence of SHS exposure, Korean women will live 41.32 years or 34.56 QALYs before discount, which corresponded to 17.29 years or 15.35 QALYs after discount. The SHS-exposed women were predicted to live 37.91 years and 31.08 QALYs before discount and 16.76 years and 14.62 QALYs after discount. The estimated lifetime healthcare cost per woman in the SHS non-exposed group was US$11 214 before the discount and US$2465 after discount. The negative impact of SHS exposure on health outcomes and healthcare costs escalated as the time horizon increased, suggesting that the adverse impact of SHS exposure may have higher impact on the later part of the lifetime. The result was consistent across a wide range of assumptions. Life expectancy might underestimate the impact of SHS exposure on health outcomes, especially if the time horizon of the analysis is not long enough. Early intervention on smoking behaviour could substantially reduce direct healthcare costs and improve quality of life attributable to SHS exposure. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Low socioeconomic status (SES) is linked to higher incidence/mortality of cardiovascular disease, but emerging evidence inconsistently reported that education level, a proxy for SES, is related to cardiovascular risk and metabolic syndrome (MetS) in Koreans. Furthermore, limited information is available on whether dietary components would mediate the relationship between education level and cardiovascular risk. We hypothesized that selected food consumption mediates the association between education level and MetS prevalence. Data from the Korea National Health and Nutritional Examination Survey (2008-2011) were included in cross-sectional analyses (n = 11,029, 30-64 years). The possible mediating effect of selected food groups (fruits, raw vegetables, red meat, milk, and soft drinks) on the association between education level and MetS was tested using a multiple mediation model. Education level was negatively associated with MetS prevalence. The association between lower education level and higher MetS prevalence was partially mediated by selected food consumption (lower intakes of fruit, red meat and milk; higher intakes of vegetable and soft drink) after adjusted for covariates. Gender also modified the association between education level and MetS prevalence that was more prominent in women than in men. Selected food consumption substantially contributes to the association between education level and MetS in Korean adults, especially among women. © 2017 S. Karger AG, Basel.

Full Text Available In light of the Korean Supreme Court's 2009 ruling favoring a patient's right to die with dignity, we evaluated trends in aggressive care in a cohort of pediatric cancer patients. Methods We conducted a population-based retrospective study that used administrative data for patients who died in 2007-2010 among the 5,203 pediatric cancer patients registered at the Korean Cancer Central Registry (KCCR during 2007-2009.In the time period covered, 696 patients died. The proportion who had received chemotherapy in the last 30 days of life decreased from 58.1% to 28.9% (P<0.001, those who received new chemotherapy in the same time period decreased from 55.2% to 15.1% (P<0.001, and those who received treatment in the last 2 weeks of life decreased from 51.4% to 21.7% (P<0.001. In the last 30 days of life, the proportion of patients whose hospital admission period was over 14 days increased from 70.5% to 82.5% (P = 0.03, the proportion who received cardiopulmonary resuscitation decreased from 28.6% to 9.6% (P<0.001, and we found no statistically significant trends in the proportion of emergency department visits, intensive care unit admissions, or mechanical ventilation.In this study, in contrast with earlier ones, the aggressiveness of end-of-life care of Korean pediatric cancer patients decreased dramatically.

To evaluate the blood flow patterns and velocities of the carotid arteries in healthy Korean adults. We evaluated the blood flow patterns and measured the peak systolic and end-diastolic velocities of the common, internal and external carotid arteries in 48 healthy adults who did not have cardiovascular disorders and neck lesions. The velocity difference was analyzed according to different age groups. In addition, peak systolic and end-diastolic velocity ratio of the internal to common carotid artery was estimated, and our data were compared with values reported by other authors. Generally, the velocity in the younger age group tends be to higher than in older group. The peak systolic and end diastolic velocities of the internal carotid artery were 84.5 cm/sec and 30.5 cm/sec. The peak systolic and end diastolic velocity ratio of the internal to common carotid artery were 0.715 and 0.966. The internal carotid artery was less resistant in blood flow than the external carotid artery. Our data were lower than the values which were reported by Bluth et al. The blood flow velocities of the internal carotid artery in healthy adults were lower than those of previous reported foreign values, but the patterns were similar

Transitions in nutrition patterns tend to emerge through industrialization and economic development. We hypothesized that the dietary patterns among South Korean adults who were 20 years or older have changed significantly from 1998 to 2010. Herein, a repeated cross-sectional analysis of data was followed for 140601 adults. We noted changes in consumption, after adjusting for age, sex, body mass index, and exercise, and tested the trends across the study period. Factor and cluster analyses were used to derive dietary patterns. A decrease in traditional Korean food consumption, including cereals, vegetables (252-176 g), and Kimchi (127-82 g), occurred, whereas fruit (172-252 g), egg, and fried food intakes increased (P dietary patterns: "Korean" diet (rice, vegetables, and Kimchi), "Western" diet (soda, eggs, and oil), and "New" diet (low sugar and high fruit and dairy product intakes). Compared to 1998, approximately 40% of participants still followed a Korean diet in 2010. Interestingly, the popularity of the Western diet fell by approximately 20%, whereas the new diet pattern increased 2-fold over the study period. Overall, these data show secular trends in dietary patterns that included a preservation of the traditional Korean diet and the emergence of a new diet pattern, and it demonstrated a unique transition in food and nutrient intakes in Korea.

To develop the Korean version of the Cognitive Assessment Scale for Stroke Patients (K-CASP) and to evaluate the test reliability and validity of the K-CASP in stroke patients. The original CASP was translated into Korean, back-translated into English, then reviewed and compared with the original version. Thirty-three stroke patients were assessed independently by two examiners using the K-CASP twice, with a one-day interval, for a total of four test results. To evaluate the reliability of the K-CASP, intra-class correlation coefficients were used. Pearson correlations were calculated and simple regression analyses performed with the Korean version of Mini-Mental State Examination (K-MMSE) and the aphasia quotient (AQ) to assess the validity. The mean score was 24.42±9.47 (total score 36) for the K-CASP and 21.50±7.01 (total score 30) for the K-MMSE.

This study evaluated dog and cat allergies and their association with allergen avoidance measures in Korean adults. The study population consisted of 537 adults who currently kept dogs or cats and participated in a pet exhibition in Korea. The subjects were asked to complete questionnaires regarding pet ownership, allergen avoidance, and allergy symptoms, and underwent skin prick tests. They were considered to have a dog or cat allergy if they suffered from one or more of allergy symptoms during contact with their pets. In total, 103 of 407 dog owners (25.3%) and 45 of 130 cat owners (34.6%) had a dog or cat allergy, respectively. Dog owners kept 1.3±1.5 dogs; this number did not differ according to the presence of dog allergy. Dog owners with a dog allergy had owned their dogs longer than those without (88.0±72.0 vs 67.5±72.7 months, PCat owners kept 2.1±3.6 cats; this number did not differ according to the presence of cat allergy, nor did the duration of cat ownership. Cat owners with a cat allergy had facial contact and slept with their cats less frequently (8.6±11.9 vs 18.3±27.0 times/day, Pcats shaved and beds cleaned less frequently than those without (1.8±3.3 vs 3.2±4.4 times/year, PCat owners with a cat allergy tried to minimize contact with their cats, but efforts to avoid indoor cat allergens were lower than those without. In comparison, dog owners with a dog allergy had kept their dogs for longer time than those without; however, current contact with their dogs and allergen avoidance measures did not differ between the 2 groups.

This qualitative study was designed to examine the benefits of leisure to older Korean women. Using a constructive grounded theory methodology, in this study we identified three categories of benefits from leisure activities: (a) developing social connections, (b) enhancing psychological well-being, and (c) improving physical health. The findings of this study demonstrate that involvement in leisure activities offers substantial physical, psychological, and social benefits for older Korean women. The results also suggest that these benefits can provide an opportunity for older Korean adults to improve their health and well-being, which, in turn, may help promote successful aging.

This retrospective study was performed to investigate the prevalence of the idiopathic osteosclerosis (IO) in Korean malocclusion patients according to age, sex, and the Angle's classification of malocclusion. This study consisted of 2,001 randomly selected patients from the Department of Orthodontics at the Gangneung-Wonju National University Dental Hospital, Korea. The prevalence of IO in Korean malocclusion patients was recorded using their panoramic radiographs, and the following parameters were surveyed; age, sex, and the Angle's classification of malocclusion. The chi-square test was analyzed to determine the statistical significance of differences in the prevalence of IO between age, sex, and the Angle's classification of malocclusion. The prevalence of IO in the jaws was 6.7% in a total of 2,001 examined orthodontic patients. The majority of IO was found in the mandible (96.58%). The 30-39 age group showed the highest prevalence of IO (9.60%). There was a higher prevalence in females (6.89%) than in males (6.45%). The prevalence of IO in Angle Class I group (7.07%) was the most frequent, followed by Angle Class II group (6.72%), and Angle Class III group (6.40%). However, there was no statistical significance in sex and Angle's classification of malocclusion. The prevalence of IO in malocclusion patients showed the differences between various age groups and most of them were found in the mandibular posterior area. However, sex and the type of malocclusion are not to be considered as a contributing factor of IO.

We compared the efficacies of vildagliptin (50 mg twice daily) relative to pioglitazone (15 mg once daily) as an add-on treatment to metformin for reducing glycosylated hemoglobin (HbA1c) levels in Korean patients with type 2 diabetes. The present study was a multicenter, randomized, active-controlled investigation comparing the effects of vildagliptin and pioglitazone in Korean patients receiving a stable dose of metformin but exhibiting inadequate glycemic control. Each patient underwent a 16-week treatment period with either vildagliptin or pioglitazone as an add-on treatment to metformin. The mean changes in HbA1c levels from baseline were -0.94% in the vildagliptin group and -0.6% in the pioglitazone group and the difference between the treatments was below the non-inferiority margin of 0.3%. The mean changes in postprandial plasma glucose (PPG) levels were -60.2 mg/dL in the vildagliptin group and -38.2 mg/dL in the pioglitazone group and these values significantly differed (P=0.040). There were significant decreases in the levels of total, low density lipoprotein, high density lipoprotein (HDL), and non-HDL cholesterol in the vildagliptin group but increases in the pioglitazone group. The mean change in body weight was -0.07 kg in the vildagliptin group and 0.69 kg in the pioglitazone group, which were also significantly different (P=0.002). As an add-on to metformin, the efficacy of vildagliptin for the improvement of glycemic control is not inferior to that of pioglitazone in Korean patients with type 2 diabetes. In addition, add-on treatment with vildagliptin had beneficial effects on PPG levels, lipid profiles, and body weight compared to pioglitazone.

Selenium is a key constituent of enzyme in glutathione peroxidase, which is effective in decreasing various types of oxidative stress, Thus, the adequacy of selenium intake is very important in decreasing the risks of various degenerating diseases such as cardiovascular disease, or certain cancers. Lately, the intake of animal foods is increasing among Koreans owing to a dietary transition toward a western style. This study was conducted to measure the selenium content in meat and eggs, and then assessed the selenium intake from these foods. Forty frequently eaten items among meat and eggs were analyzed using an Instrumental Neutron Activation Analysis. The selenium content in 100g of raw meat and eggs ranged from 8.1ug to 50.9ug. In particular, 100g of beef contained 12.4ug to 50.9ug of selenium; pork, 11.2ug to 22.6ug chicken, 10.2ug to 13.7ug and eggs, 28.6ug to 43.0ug. Thus, beef viscera and chicken eggs contain the highest amounts of selenium among these groups. 100g of Pork belly, the most frequently eaten meat type among Koreans, contains 14.6ug of selenium. An evaluation of dietary selenium intake shows that the total selenium supply from meats and eggs was 28.4ug/day and 27.5 ug/day in adult men and women, respectively. These are over one-half of the Korean RNI (Recommended Daily Intake) of 55ug/day. (author)

[A study on Horace N. Allen's medicine and recognition of Korean body].

Je Jung Won was the first modern-style Government hospital built by the Korean King Ko-Jong in April 1885, and it was the medical missionary Horace Newton Allen(1858~1932) who made one of the greatest contributions to the establishment of the hospital. Allen was an American missionary. He graduated from Ohio Wesleyan University with a degree in theology in 1881, and completed one-yearcourse at Miami Medical College. In Korea and America he worked as a physician, a missionary, an American diplomatic minister to Korea and a Korean minister's secretary to America. While acting as a mediator between Korea and America, he knew and recorded the domestic and foreign situation of Korea during Gaehwagi(the civilized and enlightened age). Thus to study him is to understand Korea's Gaehwagi as well as to research American medical missionaries. During his stay in Korea(1884~1905), Allen steadily wrote diaries and letters about Korean politics, diplomacy, society, culture, and medicine. Thus his public/private record through diaries and letters(the quantity of these materials amounts to several thousands) supplements the Korean early modern era's historical record. However, until now these materials have received little scholarly attention from researchers except for a few historians of missionary work between Korea and America, or of Korean modern medicine. I intended to use these materials to suggest a new perspective on the study of Korean Gaehwagi. Allen, along with John W. Heron, who came to Seoul on June 21st 1885, treated about 10,460 Korean patients in the first year of the opening of JeJungWon. They made "the first annual report of the Korean Government Hospital". This report explained how Allen and Heron regarded and treated Korean patients. Allen's diaries, letters and other writings offer a realistic view of how the western people actually recognized the Korean people at that time. As a western doctor, Allen had an ambivalent attitude toward Korean medical concepts

Although regular exercise has been recommended to reduce the risk of cardiovascular disease (CVD) among people with metabolic syndrome, little information is available about psychobehavioral strategies in this population. The purpose of this study was to identify the stages, processes of change, decisional balance, and self-efficacy of exercise behavior and to determine the significant predictors explaining regular exercise behavior in adults with metabolic syndrome. This descriptive, cross-sectional survey design enrolled a convenience sample of 210 people with metabolic syndrome at a university hospital in South Korea. Descriptive statistics were used to analyze demographic characteristics, metabolic syndrome risk factors, and transtheoretical model-related variables. A multivariate logistic regression analysis was used to determine the most important predictors of regular exercise stages. Action and maintenance stages comprised 51.9% of regular exercise stages, whereas 48.1% of non-regular exercise stages were precontemplation, contemplation, and preparation stages. Adults with regular exercise stages displayed increased high-density lipoprotein cholesterol level, were more likely to use consciousness raising, self-reevaluation, and self-liberation strategies, and were less likely to evaluate the merits/disadvantages of exercise, compared with those in non-regular exercise stages. In this study of regular exercise behavior and transtheoretical model-related variables, consciousness raising, self-reevaluation, and self-liberation were associated with a positive effect on regular exercise behavior in adults with metabolic syndrome. Our findings could be used to develop strategies and interventions to maintain regular exercise behavior directed at Korean adults with metabolic syndrome to reduce CVD risk. Further prospective intervention studies are needed to investigate the effect of regular exercise program on the prevention and/or reduction of CVD risk among this

To evaluate Korean physiatrists' practice of performing intramuscular botulinum toxin injection in anticoagulated patients and to assess their preference in controlling the bleeding risk before injection. As part of an international collaboration survey study, a questionnaire survey was administered to 100 Korean physiatrists. Physiatrists were asked about their level of experience with botulinum toxin injection, the safe international normalized ratio range in anticoagulated patients undergoing injection, their tendency for injecting into deep muscles, and their experience of bleeding complications. International normalized ratio injection by 41% of the respondents. Thirty-six respondents replied that the international normalized ratio should be lowered to sub-therapeutic levels before injection, and 18% of the respondents reported that anticoagulants should be intentionally withheld and discontinued prior to injection. In addition, 20%-30% of the respondents answered that they were uncertain whether they should perform the injection regardless of the international normalized ratio values. About 69% of the respondents replied that they did have any standardized protocols for performing botulinum toxin injection in patients using anticoagulants. Only 1 physiatrist replied that he had encountered a case of compartment syndrome. In accordance with the lack of consensus in performing intramuscular botulinum toxin injection in anticoagulated patients, our survey shows a wide range of practices among many Korean physiatrists; they tend to avoid botulinum toxin injection in anticoagulated patients and are uncertain about how to approach these patients. The results of this study emphasize the need for formulating a proper international consensus on botulinum toxin injection management in anticoagulated patients.

The correlation between the plasma insulin, and glucose concentration was studied in healthy Korean adults consisting of 20 males and 22 females of 16 to 38 years of age. The blood samples of above subjects were obtained through cubital vein at arbitrary times during their usual working hours. Plasma insulin was assayed by means of double antibody system of radioimmunoassay technics, and blood glucose was determined by means of Van Slyke-Folch method. Results were as follows : 1. There were no differences in the blood sugar levels in relation to the plasma insulin concentration either by sex or age. 2. In the case, when the plasma insulin concentration was within 50 mmuU/ml, the correlation between the insulin, and glucose concentration existed, the ratio of which was expressed as; Plasma glucose concentration (mg/dl)=91.9 + 0.08 X Insulin concentration r=0.62. 3. Insulinogenic index was 12.4%, which was somewhat higher than other reports. 4. It is suggested that the correlation between plasma insulin and glucose concentration could be determined at arbitrary times instead of fasting times.

This study was conducted to generate and validate a cross-culturally adapted Korean version of the xerostomia inventory (XI), an 11-item questionnaire designed to measure the severity of xerostomia. The original English version of the XI was translated into Korean according to the guidelines for cross-cultural adaptation of health-related quality-of-life measures. Among a prospective cohort of primary Sjögren's syndrome (pSS) in Korea, 194 patients were analyzed. Internal consistency was evaluated by using Cronbach's alpha, and test-retest reliability was obtained by using an intraclass correlation coefficient (ICC) analysis. Construct validity was investigated by performing a correlation analysis between XI total score and salivary flow rate (SFR). Cronbach's alpha for internal consistency was 0.868, and the ICC for test-retest reliability ranged from 0.48 to 0.827, with a median value of 0.72. Moderate negative correlations between XI score and stimulated SFR, unstimulated SFR, and differential (stimulated minus unstimulated) SFR were observed (Spearman's rho, ρ = -0.515, -0.447, and -0.482, respectively; P xerostomia in the pSS patients. In conclusion, the Korean version of the XI is a reliable tool to estimate the severity of xerostomia in patients with pSS.

Although animal experiments have shown that cadmium exposure induces alterations in lipid profiles, no epidemiological study of this relationship has been performed. The objective of this study was to evaluate the association between blood cadmium concentration and blood lipid levels in Korean adults. A cross-sectional study comprising participants (n=3903) aged 20 years or older from the 2005, 2008, and 2009 Korea National Health and Nutrition Examination Surveys was conducted. Demographic characteristics and dietary intake were obtained from the participants by questionnaire, and cadmium and lipid levels were determined by analysis of blood samples. After adjusting for demographic and dietary factors, blood concentration of cadmium was positively associated with the risk of low high-density lipoprotein cholesterol (HDL-C) in a dose-dependent manner (p for trend <0.001). In addition, the odds ratios (ORs) of a high triglyceride to HDL-C ratio was significantly increased in the high blood cadmium groups [OR=1.36; 95% confidence interval (CI), 1.03–1.79 for fourth quintile and OR=1.41; 95% CI, 1.07–1.86 for fifth quintile] compared with the lowest quintile group. However, high blood cadmium was not associated with a risk of high total cholesterol, high low-density lipoprotein cholesterol, or high triglycerides. These data suggest that an increased cadmium body burden increases the risk of dyslipidemia, mainly due to the increased risk of low HDL-C and the high ratio of triglycerides to HDL-C.

This study evaluated the efficacy and safety of a 3-day aprepitant regimen for the prevention of chemotherapy-induced nausea and vomiting (CINV) during the first cycle of non-anthracycline plus cyclophosphamide (AC)-based moderately emetogenic chemotherapy (MEC) based on government guidelines in Korean patients. This multicenter, randomized, double-blind, phase IV trial (NCT01636947) enrolled adult South Korean patients with a broad range of tumor types who were scheduled to receive a single dose of ≥1 MEC agent. Patients were randomized to a 3-day regimen of aprepitant (aprepitant regimen) or placebo (control regimen) on top of ondansetron plus dexamethasone. The primary and key secondary efficacy endpoints were the proportions of subjects who achieved no vomiting and complete response (CR) during the overall phase. Of the 494 randomized subjects, 480 were included in the modified intent-to-treat population. Response rates for no vomiting and CR in the overall phase were numerically higher for the aprepitant regimen compared with the control regimen groups, but failed to reach statistical significance (no vomiting 77.2 vs 72.0%; p = 0.191; CR 73.4 vs 70.4%; p = 0.458). Both the aprepitant and control regimens were generally well tolerated. A 3-day aprepitant regimen was numerically better but not statistically superior to a control regimen with respect to the achievement of no vomiting or CR during the overall phase in a non-AC MEC Korean population based on government reimbursement guidelines.

Full Text Available BackgroundWe compared the efficacies of vildagliptin (50 mg twice daily relative to pioglitazone (15 mg once daily as an add-on treatment to metformin for reducing glycosylated hemoglobin (HbA1c levels in Korean patients with type 2 diabetes.MethodsThe present study was a multicenter, randomized, active-controlled investigation comparing the effects of vildagliptin and pioglitazone in Korean patients receiving a stable dose of metformin but exhibiting inadequate glycemic control. Each patient underwent a 16-week treatment period with either vildagliptin or pioglitazone as an add-on treatment to metformin.ResultsThe mean changes in HbA1c levels from baseline were –0.94% in the vildagliptin group and –0.6% in the pioglitazone group and the difference between the treatments was below the non-inferiority margin of 0.3%. The mean changes in postprandial plasma glucose (PPG levels were –60.2 mg/dL in the vildagliptin group and –38.2 mg/dL in the pioglitazone group and these values significantly differed (P=0.040. There were significant decreases in the levels of total, low density lipoprotein, high density lipoprotein (HDL, and non-HDL cholesterol in the vildagliptin group but increases in the pioglitazone group. The mean change in body weight was –0.07 kg in the vildagliptin group and 0.69 kg in the pioglitazone group, which were also significantly different (P=0.002.ConclusionAs an add-on to metformin, the efficacy of vildagliptin for the improvement of glycemic control is not inferior to that of pioglitazone in Korean patients with type 2 diabetes. In addition, add-on treatment with vildagliptin had beneficial effects on PPG levels, lipid profiles, and body weight compared to pioglitazone.

To evaluate the inherent value of breast cancer therapy a willingness-to-pay (WTP) study was conducted in Korean patients with metastatic breast cancer. Patients were prospectively enrolled from four study centers and completed quality of life questionnaires to reflect their status pre-cancer and their current health status. Clinical and socioeconomic data were collected to characterize the population and utilize during modeling. Patients' WTP for breast cancer treatment was assessed using an open-ended question following three rounds of bidding to better hone in on their maximal WTP, starting with one of three randomly assigned start bids. Predictors of patient WTP was evaluated using linear regression models. Associations between WTP and other parameters were evaluated with correlations. Korean metastatic breast cancer patients were WTP an average of KRW 8 696 329 (US$7555) per month to return to their pre-cancer health state, with those who were recently diagnosed as WTP the most (KRW 12 955 000 [$11 254]). WTP was closely associated with the patient's education level, income, personal financial difficulties, Eastern Cooperative Oncology Group performance status, and their experience of arm symptoms. The results suggest that patients are WTP significant amounts per month for treatment. Breast cancer patients are heavily burdened physically, mentally and financially, and the present study indicated this significant financial burden by disclosing its relationship with WTP. Providing a better understanding of the inherent value of treatment will allow Koreans to better evaluate treatment in the coming era of personalized medicine. © 2012 Wiley Publishing Asia Pty Ltd.

IBTR! 2.0 is a web-based nomogram that predicts the 10-year ipsilateral breast tumor recurrence (IBTR) rate after breast-conserving therapy. We validated this nomogram in Korean patients. The nomogram was tested for 520 Korean patients, who underwent breast-conserving surgery followed by radiation therapy. Predicted and observed 10-year outcomes were compared for the entire cohort and for each group, predefined by nomogram-predicted risks: group 1, 10%. In overall patients, the overall 10 year predicted and observed estimates of IBTR were 5.22% and 5.70% (p=0.68). In group 1, (n=124), the predicted and observed estimates were 2.25% and 1.80% (p=0.73), in group 2 (n=177), 3.95% and 3.90% (p=0.97), in group 3 (n=181), 7.14% and 8.80% (p=0.42), and in group 4 (n=38), 11.66% and 14.90% (p=0.73), respectively. In a previous validation of this nomogram based on American patients, nomogram-predicted IBTR rates were overestimated in the high-risk subgroup. However, our results based on Korean patients showed that the observed IBTR was higher than the predicted estimates in groups 3 and 4. This difference may arise from ethnic differences, as well as from the methods used to detect IBTR and the healthcare environment. IBTR! 2.0 may be considered as an acceptable nomogram in Korean patients with low- to moderate-risk of in-breast recurrence. Before widespread use of this nomogram, the IBTR! 2.0 needs a larger validation study and continuous modification.

Vitamin D modulates innate and adaptive immune responses, and vitamin D deficiency is associated with increased mortality in hospitalized patients with pneumonia. We evaluated the prevalence of vitamin D deficiency in Korean patients with acute respiratory distress syndrome (ARDS) and its effect on the clinical outcomes of ARDS. We retrospectively analyzed the data of 108 patients who had a measured serum level of 25-hydroxy vitamin D3 (25(OH)D3) at the time of diagnosis with ARDS. The clinical outcomes were evaluated based on 25(OH)D3 levels of 20 ng/mL and stratified by quartiles of 25(OH)D3 levels. The mean age of patients was 59.4 years old; 77 (71.3%) were male. Vitamin D deficiency was found in 103 patients (95.4%). The mean 25(OH)D3 level was 8.3 ± 7.0 ng/mL. Neither in-hospital mortality (40.0% vs. 68.0%) nor 6-month mortality (40.0% vs. 71.8%) significantly differed between groups. There were no significant differences in 25(OH)D3 level between survivors (8.1 ± 7.6 ng/mL) and non-survivors (8.5 ± 6.8 ng/mL, p = 0.765). There were no trends toward a difference in mortality among quartiles of 25(OH)D3 levels. However, 25(OH)D3 levels were inversely related with length of hospital stay and intensive care unit stay among in-hospital survivors. Vitamin D deficiency was prevalent in Korean patients with ARDS. However, levels of vitamin D were not associated with mortality. A large, prospective study is needed to evaluate the effects of vitamin D deficiency on clinical outcomes of ARDS.

Full Text Available Background: Guidelines for esophagogastroduodenoscopy (EGD in the West allow the continued use of warfarin under therapeutic international normalized ratio (INR level. In Korea, no guidelines have been issued regarding warfarin treatment before EGD. The authors surveyed Korean cardiac surgeons about how Korean cardiac surgeons handle warfarin therapy before EGD using a questionnaire. Participants were requested to make decisions regarding the continuation of warfarin therapy in two hypothetical cases. Methods: The questionnaire was administered to cardiac surgeons and consisted of eight questions, including two case scenarios. Results: Thirty- six cardiac surgeons at 28 hospitals participated in the survey, and 52.7% of the participants chose to stop warfarin before EGD in aortic valve replacement patients without risk factors for thromboembolism. When the patient’s INR level was 2, 31% of the participants indicated that they would choose to continue warfarin therapy. For EGD with biopsy, 72.2% of the participants chose warfarin withdrawal, and 25% of the participants chose heparin replacement. In mitral valve replacement patients, 47.2% of the participants chose to discontinue warfarin, and 22.2% of the participants chose heparin replacement. For EGD with biopsy in patients with a mitral valve replacement, 58.3% of the participants chose to stop warfarin, and 41.7% of the participants chose heparin replacement. Conclusion: This study demonstrated that attitudes regarding warfarin treatment for EGD are very different among Korean surgeons. Guidelines specific to the Korean population are required.

Osteoporosis is a major health problem that will grow in burden with ageing of the global population. Modifiable risk factors for osteoporosis, including diet, have significant implications for disease prevention. We examined associations between dietary patterns and bone mineral density (BMD) in a Korean adult population. In total, 1828 individuals from the Healthy Twin Cohort were included as subjects. Information on general characteristics, lifestyles and health status was obtained through a health examination, and BMD was assessed using DEXA. Dietary intake was assessed using a 3-day food record, and dietary patterns were examined by factor analysis. Associations between dietary patterns and BMD were examined using mixed linear regression, adjusting for family and twin structure as well as other potential risk factors for bone health. Four dietary patterns were identified (Rice and kimchi; eggs, meat and flour; Fruit, milk and whole grains; and Fast food and soda). The 'Fruit, milk and whole grains' pattern was associated with a reduced risk of having low BMD in men (odds ratio (OR)=0.38; 95% confidence interval (CI)=0.22-0.67) and women (OR=0.45; 95% CI=0.28-0.72) and was positively associated with BMD at multiple sites. The 'rice and kimchi' pattern had a positive association with only whole-arm BMD in men and women. Our results suggest that a dietary pattern with high intake of dairy products, fruits and whole grains may contribute positively to bone health in a Korean adult population, and dietary pattern-based strategies could have potential in promoting bone health.

The presented study aimed to evaluate the selenium and zinc status of Korean middle -aged male patients with CHD. The serum concentration of zinc and selenium was measured by Neutron activation analysis method. The mean serum selenium and zinc concentrations of patients were 94.9 μg/l and 826.4 μg/l, respectively compared to the 97.8μg/l, 891.6 μg/l of control group, showing no any difference in selenium status, but showed significant difference for zinc status of middle -aged men. The deficiency of zinc in control group was 9.8%, but that was 31.3% in patient group. Conclusively, this study indicated that zinc status, which is associated with inflammatory reaction, is low in Korean male patients with CHD

The aim of this study was to describe pancreatic involvement in von Hippel-Lindau (VHL) disease and to document the changes that occur in pancreatic lesions. We retrospectively analyzed the medical records and CT scans of 18 VHL patients who were diagnosed between 1994 and 2007 at the Samsung Medical Center. The clinical history with a detailed family history, biochemical test results, and imaging studies of the pancreas, adrenal glands, and kidneys were reviewed. Genetic analysis was performed in 12 patients. The changes in pancreatic lesions, such as an increase in cystic lesions, calcifications, and dilatation of the pancreatic duct, were analyzed in patients who had CT scans at least 1 year apart. Pancreatic lesions existed in 89% (16/18) of the patients. All 16 patients had multiple cystic lesions. Two patients had co-existing neuroendocrine tumors (NET), and two patients had co-existing serous cystadenomas (SCA). At least one of three features of pancreatic lesions (cystic lesions, calcifications, and dilatation of the pancreatic duct) progressed in all nine patients who had CT scans 1 year apart. Pancreatic involvement in VHL disease was relatively common in Korean patients. The most common type of pancreatic involvement was a multiple cystic lesion. NET and SCA existed in approximately 10% of VHL patients with pancreatic involvement. Pancreatic lesions in VHL disease progressed, at least according to radiological images. (author)

Full Text Available Overactive bladder (OAB is a prevalent condition characterized by lower urinary tract symptoms (LUTS. Age, education, income, marital status, sleep, and emotional problems have been associated with OAB; however, conflicting results exist. The present study was conducted to estimate the prevalence of OAB and comprehensively analyze its associated factors in a large cross-sectional, population-based study. The data of 94,554 participants aged 19-107 were analyzed from the Korean Community Health Survey (KCHS of 2012. Data on marital status, physical activity, education level, occupation, body mass index (BMI, income level, sleep time, and stress level were retrieved for all enrolled participants. The overactive bladder symptom score (OABSS was used to evaluate the presence and degree of OAB. Simple and multiple logistic regression analyses with complex sampling were used for the associations between various factors and the presence of OAB. Overall, OAB was present in approximately 2.9% of the participants. The prevalence of OAB increased with age and steeply increased after 60 years of age (adjusted odds ratio [AOR] for each 10 years = 1.70, 95% confidence interval [CI] = 1.61-1.80, P 2.16 (1.88-2.48 > 1.39 (1.23-1.57 for severe stress > moderate stress > some stress, respectively, P<0.001]. A medical history of diabetes mellitus, hyperlipidemia, and/or cerebral stroke was significantly related to OAB. Approximately 2.9% of adult Korean men experienced OAB based on the OABSS. Unmarried status; occupation; being underweight; inadequate sleep; stress; and medical history of diabetes mellitus, hyperlipidemia, or cerebral stroke were significantly correlated with OAB.

Objective We evaluated the Foundation for the National Institutes of Health (FNIH) Sarcopenia Project’s recommended criteria for sarcopenia’s association with mortality among older Korean adults. Methods We conducted a community-based prospective cohort study which included 560 (285 men and 275 women) older Korean adults aged ≥65 years. Muscle mass (appendicular skeletal muscle mass-to-body mass index ratio (ASM/BMI)), handgrip strength, and walking velocity were evaluated in association with all-cause mortality during 6-year follow-up. Both the lowest quintile for each parameter (ethnic-specific cutoff) and FNIH-recommended values were used as cutoffs. Results Forty men (14.0%) and 21 women (7.6%) died during 6-year follow-up. The deceased subjects were older and had lower ASM, handgrip strength, and walking velocity. Sarcopenia defined by both low lean mass and weakness had a 4.13 (95% CI, 1.69–10.11) times higher risk of death, and sarcopenia defined by a combination of low lean mass, weakness, and slowness had a 9.56 (3.16–28.90) times higher risk of death after adjusting for covariates in men. However, these significant associations were not observed in women. In terms of cutoffs of each parameter, using the lowest quintile showed better predictive values in mortality than using the FNIH-recommended values. Moreover, new muscle mass index, ASM/BMI, provided better prognostic values than ASM/height2 in all associations. Conclusions New sarcopenia definition by FNIH was better able to predict 6-year mortality among Korean men. Moreover, ethnic-specific cutoffs, the lowest quintile for each parameter, predicted the higher risk of mortality than the FNIH-recommended values. PMID:27832145

Purpose The purpose of the present study was to examine the validity and reliability of the Korean version of the Eating Disorder Inventory-2 (EDI-2) in Korean patients with eating disorders and healthy controls, and to investigate cultural differences of EDI-2 between a Korean group and a North American standardization sample. Materials and Methods The Korean version of the EDI-2 was prepared after comprehensive clinical assessment of Korean patients with eating disorders (n=327) as well as female undergraduates (n=176). Results were compared between eating disorder subgroups (anorexia nervosa, bulimia nervosa and eating disorders not otherwise specified) and those of a North American standardization sample and healthy controls. Results The results showed that the Korean EDI-2 had adequate internal consistency (0.77-0.93) and discriminated well between patients with eating disorders and healthy controls on all subscales. Significant differences in EDI-2 subscale scores between the eating disorder groups and the healthy control group were observed; however, there was no discernible difference among the eating disorder subgroups. When compared with a North American standardization sample, the Korean control group showed significantly higher scores for drive for thinness and asceticism. When patient groups were compared, the Korean group showed significantly lower scores for perfectionism. Conclusion As expected, the results accurately reflected psychometric properties of the Korean version of EDI-2 for eating disorder patients in Korea. These findings also suggest that common characteristics for the eating disorder exist as a whole rather than with significant difference between each subgroup. In addition, significant differences between the Korean and the North American groups for both patients and controls also demonstrated specific cultural differences. PMID:23074108

Full Text Available This paper aims to explain the adaptation of North Korean elite defectors who fled from North Korea. Data used for the purpose of this article came from surveys of North Korean defectors conducted in the late 2000’s. Findings of the realized research indicate that the majority of senior defectors are experiencing less psychological and material issues when adjusting to society than regular North Korean defectors. The paper will proceed in three steps: explaining the notion of defectors, outlining their background, and focusing on their adaptation in South. Although defectors as a whole has emerged as of the most research group as a minority in South Korea, the so-called senior defectors have hardly been spotlighted. Basically North Korean senior defectors are supposed to strengthen the anti-Kim movement and legitimize the power of the South Korean government and the image of South Korea abroad. What has to be enlightened upon is the fact that North Korean senior defectors partially disagree with the integration policy of South Korean authorities. A major research question emerges: How are the experience of elite defectors localized in South Korea? How do their specific identities impact their opinion within the South Korean society? The aim of the article is also to categorize senior defectors and to provide in a single document a list of senior North Korea defectors based abroad. This kind of information is only available for Korean speaking readers. I wanted to make it accessible to the Englishspeaking community.

This study investigated the relationship between oral hygiene conditions, activities of daily living (ADL) and cognitive ability in older Korean patients in long-term care facilities. Ninety older persons (65+) were randomly sampled from a possible 112 residents in a single facility. They participated in a 2-month-long survey. The Korean Modified Barthel Index was used to measure the ADL, and cognitive ability was measured using the Mini-Mental State Examination, Korean version. Oral hygiene status was measured using the Simplified Oral Hygiene Index and the Tongue Coating Index (TCI). Older participants with complete dependence manifested significantly poorer oral hygiene (P oral hygiene (P oral hygiene on tooth surfaces, while participants with partial dependence had poor tongue hygiene. In addition, dentulous older participants had poorer tongue hygiene than edentulous ones. This indicates the need to assess tooth status and provide oral care services via ADL in long-term care facilities. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The year 2012 was the 50th anniversary of the Korean Neurosurgical Society, and in 2013, the 15th World Congress of Neurosurgery took place in Seoul, Korea. Thus, it is an appropriate occasion to introduce the world to the history of the Korean Neurosurgical Society and the foundation, development, and growth of Korean neurosurgery. Historical materials and pictures were collected and reviewed from the history book and photo albums of the Korean Neurosurgical Society. During the last 50 years, the Korean Neurosurgical Society and Korean neurosurgery have developed and grown enormously not only in quantity but also in quality. In every aspect, the turning point from the old to the new era of the Korean Neurosurgical Society and Korean neurosurgery was the year 1980. Copyright © 2015. Published by Elsevier Inc.

The possible effects of dairy product intake against obesity have been suggested in animal studies; however, the association is still not well established in epidemiological studies. Few studies in Asian countries with relatively low intake of dairy products exist. We investigated the association between dairy products and calcium intake and obesity in Korean population with relatively low intake of dairy products. Our study population consisted of adults (n = 7173) aged 19-64 among participants of the 2007, 2008 and 2009 Korean National Health and Nutrition Examination Survey who had not made any attempt of intentional weight loss. Dietary intake data from food frequency questionnaire (FFQ) and 24-hour recall were used. Dairy products included milk and yogurt in the FFQ. Obesity was defined as BMI≥25 kg/m². Higher frequency of dairy product intake was associated with a reduced prevalence of obesity (OR = 0.63; 95% CI = 0.45-0.89 for ≥2 times/day vs. ≤1 time/month; p for trend = 0.003) using the intake data from FFQ. Similarly, high frequency of milk or yogurt intake had an inverse association with obesity. The association between milk and yogurt intake and obesity was similar when the intake from 24-hour recall was examined. Higher calcium intake from dairy products as well as total dietary calcium intake was associated with a decreased prevalence of obesity (OR = 0.83; 95% CI = 0.71-0.98 for highest vs. lowest quintile of dairy calcium intake; p for trend = 0.02, OR = 0.78; 95% CI = 0.64-0.94 for highest vs. lowest quintile of total calcium intake; p for trend = 0.04). The associations appeared to be stronger in women than in men. These results suggest that high consumption of dairy products is associated with a lower prevalence of obesity and that calcium in dairy products may be one of the components contributing to the association. Further longitudinal studies are warranted to replicate our findings.

To investigate the genetic association between unrelated Korean keratoconus patients and interleukin 1 alpha (IL1A), interleukin 1 beta (IL1B), and IL1 receptor antagonist (IL1RN) gene polymorphisms. We investigated the association between IL1A (rs1800587, rs2071376, and rs17561), IL1B (rs1143627, rs16944, rs1143634, and rs1143633), and IL1RN (rs419598, rs423904, rs424078, and rs315952, variable number tandem repeat [VNTR]) polymorphisms in 100 unrelated Korean keratoconus patients. One hundred control individuals without any corneal disease were selected from the general population. Polymerase chain reaction (PCR) - restriction fragment length polymorphism (RFLP) analysis and direct sequencing were used to screen for genetic variations in the IL1 gene cluster. Haplotypes for the IL1 gene cluster were constructed using Haploview version 4.0. We analyzed a total of 12 polymorphic sites in the IL1 gene cluster. Among them, the -511 (rs16944) and -31 (rs1143627) positions in the promoter region of IL1B were significantly different between patient and control groups. The C allele of rs16944 (-511C>T, p=0.022, odds ratio of risk [OR]=1.46, 95% confidence intervals [CI] 0.94C, p=0.025, OR=1.43, 95% CI 0.92<2.22) were associated with a significantly increased risk of keratoconus in Korean patients. Linkage of the two alleles, -31*C and -511*T, was associated with an increased risk for keratoconus with OR=2.38 (p=0.012, 95% CI=1.116-5.046). The *C/*A genotype of rs2071376 in IL1A intron 6 was significantly different between the keratoconus patients and control subjects (p=0.034, OR=0.59, 95% CI 0.32<1.11). Other polymorphisms did not show an association with keratoconus risk. This is the first report of IL1 gene cluster mutation screening in Korean keratoconus patients. Significant differences in allelic frequency of IL1B between keratoconus patients and the control group suggest that IL1B polymorphisms may play a role in the susceptibility of unrelated Koreans to develop

Proper physical activities are known to be helpful in the prevention and management of chronic diseases. However, the physical activity level of patients with chronic diseases is low. Therefore, this study aimed to investigate the physical activity compliance of patients with hypertension, diabetes, and dyslipidemia in Korea. This study analyzed the 2010-2012 Fifth Korean National Health and Nutrition Examination Survey data. We included 13,873 individuals in the analysis. The level of physical activity compliance was measured by performing multivariate logistic regression analyses. In the univariate analysis, the subjects with hypertension or diabetes tended to comply with the physical activity guidelines less faithfully than their healthy counterparts. The proportion of subjects with hypertension who were insufficiently physically active was 65.4% among the men and 75.8% among the women. For diabetes, the proportions were 66.7% and 76.8%, respectively. No significant difference was found between the subjects with dyslipidemia and their healthy counterparts. In the multivariate logistic regression analysis, no significant difference in physical activity compliance was observed between the subjects with hypertension, diabetes, or dyslipidemia and their healthy counterparts for both sexes. The patients with hypertension or diabetes tended to have lower physical activity prevlaence than their healthy counterparts. However, for dyslipidemia, no significant difference was found between the two groups. Given the significance of physical activities in the management of chronic diseases, the physical activities of these patients need to be improved.

Illicit Drug Use Among South Korean Offenders: Assessing the Generality of Social Learning Theory.

Yun, Minwoo; Kim, Eunyoung

2015-10-01

Since the mid-1990s, illicit drug use has become a problem in Korean society. This trend is likely due to the rapid globalization and expansion that occurred with the Internet revolution, which led to greater numbers of people socially learning about drug culture. The current study attempts to uncover criminogenic causality of such social learning about drug use by studying adult felony drug offenders in South Korea. The data used for the study were obtained from self-reported surveys, originally collected by the Korean Institution of Criminology (KIC). The final sample comprised 1,452 felony offenders convicted of illicit drug use, and their responses were analyzed with a set of multiple logistic regression tests. The current study found supportive evidence for the generalizability of social learning theory from the sample of the South Korean adult drug offenders. We argue that the current study provides additional empirical evidence that supports the generalizability of social learning theory. © The Author(s) 2014.

Coping strategies have significant effects on older people's health. This study examined whether gender and ethnic differences influence the coping strategies chosen by older adults when they encounter daily life stressors. Data were collected from 444 community-dwelling people over the age of 65, including 238 Caucasian Americans and 206 Korean Americans. Results showed significant differences between the two groups. Korean Americans had higher scores on problem and emotion-focused coping strategies as well as avoidant coping strategies than Caucasian Americans. Caucasian older women employed more active coping, planning, and positive reframing skills; relied more on religion; and sought emotional support more than Caucasian men. For Korean Americans, older women utilized religion and denial; whereas older men employed instrumental support and substance abuse. The results suggest that practitioners should develop ethnic, gender-specific programs to help older adults cope more effectively with their daily life stressors.

Hypertriglyceridemic waist phenotype is a simple screening parameter to identify people at increased risk for cardiovascular disease. We evaluated whether hypertriglyceridemic waist (HTGW) phenotype increases the risk for coronary artery calcification (CAC) in apparently healthy Korean adults. A total of 32,186 participants (mean age 41.3, 80.2% men) in a health screening program, in whom the coronary artery calcium score (CACS) was measured, were analyzed. Subjects were divided into four groups: 1) normal waist circumference (WC)-normal triglyceride (TG) (NWNT), 2) normal WC-high TG (NWHT), 3) enlarged WC-normal TG (EWNT), and 4) enlarged WC-high TG (EWHT). Enlarged WC was defined as WC ≥ 90 cm for men and ≥ 85 cm for women; high serum TG was defined as TG ≥ 150 mg/dL. The presence of CAC was defined by CACS >0, and CACS was analyzed in a logarithmized form of CACS plus 1 {ln(CACS+1)}. A total of 14.9% of the participants had CAC. The EWHT group showed the highest mean value for ln(CACS+1) among the four groups. The EWHT group showed the highest odds ratio for CAC, with NWHT group the second, and with EWNT group the third compared with the NWNT group after adjusting for confounding variables (1.579, 1.302, and 1.266 vs. NWNT). The EWHT group showed the highest association for CAC, suggesting this HTGW phenotype as a useful marker for the detection of subjects with high cardiometabolic risk in healthy Korean adults.

This phase III placebo-controlled study evaluated the immunogenicity and safety of MenACWY-CRM vaccination in healthy Korean adolescents and adults. Serum bactericidal activity with human complement (hSBA) was measured before and 1 month after vaccination against all four meningococcal serogroups. The IgG concentration specific for serogroup W capsular polysaccharide was measured in a subset of subjects in a post-hoc analysis. Adverse reactions were monitored throughout the study. Four hundred and fifty subjects were randomized 2:1 to receive MenACWY-CRM (N=297) or a saline placebo (N=153). MenACWY-CRM induced a good immune response against all four serogroups, with seroprotection rates (hSBA titers ≥8) of 79%, 99%, 98%, and 94% for serogroups A, C, W, and Y, respectively. Seroresponse rates were high for serogroups A, C, and Y, i.e. 76%, 86%, and 69%, respectively; the rate for serogroup W was 28%. MenACWY-CRM vaccine induced serum bactericidal antibodies against all four serogroups in a majority of subjects regardless of their baseline hSBA titers. MenACWY-CRM was generally well tolerated with most reactions being transient and mild to moderate in severity. Findings of this first study of a quadrivalent meningococcal polysaccharide conjugate vaccine in Korean adults and adolescents demonstrated that a single dose of MenACWY-CRM was well tolerated and immunogenic, as indicated by the percentages of subjects with hSBA titers ≥8 (79%, 99%, 98%, and 94% of subjects) and geometric mean titers (48, 231, 147, and 107) against serogroups A, C, W, and Y, respectively, at 1 month post-vaccination.

The aim of this study was to explore the reliability and validity of the Korean version of the Cornell Scale for Depression in Dementia (CSDD-K), a scale for assessment of depression in dementia. The original CSDD was translated into Korean and the content was verified through back-translation procedures. This study included 59 depressive patients with Alzheimer's disease (AD), 62 non-depressive patients with AD and 36 healthy elderly controls. The subjects were assessed using CSDD-K, the 17-item Hamilton Depression Rating Scale (HAM-D(17)), the 15-item Korean version of Geriatric Depression Scale (GDS(15)) and the Korean version of Mini-mental Status Examination (MMSE-K). In the reliability test, Cronbach's α coefficient and test-retest reliabilities were 0.92 and 0.91, respectively, indicating that the CSDD-K has good internal consistency. There were significant differences in CSDD-K total scores between AD patients with depression and AD patients without depression (preliability and validity for the assessment of depressive symptom severity in AD patients. The CSDD-K is a useful instrument for assessing AD patients with depressive symptoms in Korean ethnic population.

To externally validate the simplified acute physiology score 3 (SAPS3) and to customize it for use in Korean intensive care unit (ICU) patients. This is a prospective multicentre cohort study involving 22 ICUs from 15 centres throughout Korea. The study population comprised patients who were consecutively admitted to participating ICUs from 1 July 2010 to 31 January 2011. A total of 4617 patients were enrolled. ICU mortality was 14.3%, and hospital mortality was 20.6%. The patients were randomly assigned into one of two cohorts: a development (n = 2309) or validation (n = 2308) cohort. In the development cohort, the general SAPS3 had good discrimination (area under the receiver operating characteristics curve = 0.829), but poor calibration (Hosmer-Lemeshow goodness-of-fit test H = 123.06, P Customization was achieved by altering the logit of the original SAPS3 equation. The new equation for Korean ICU patients was validated in the validation cohort, and demonstrated both good discrimination (area under the receiver operating characteristics curve = 0.835) and good calibration (H = 4.61, P = 0.799, C = 5.67, P = 0.684). General and regional Australasia SAPS3 admission scores showed poor calibration for use in Korean ICU patients, but the prognostic power of the SAPS3 was significantly improved by customization.

Full Text Available Objective:There has been no known report on the pain shock after administering Korean bee-venom therapy. Three accounts of pain shock were observed at the Sangji university affiliated Oriental medicine clinic from July 2001 through September 2001. This thesis will inform clinical progression and cautions on administering Korean bee-venom therapy. Method:We were able to witness different patterns of pain shock during the treatment of degenerative knee joint, progressive oral paralysis, and A.L.S. In order to reduce heat toxicity of the bee venom, needling points were first massaged with the ice for 10 minutes before injecting 0.1～0.2cc of the bee venom. Points of injection were ST36, LI11, LI4 and others. Pain shock occurred after injecting on inner xi-an, outer xi-an and LI4. The phenomena associated with pain shock was recorded in chronological order and local changes were examined. Result Through examining 3 patients with the pain shock, we managed to observe clinical progression, duration, and time linked changes on specific regions. We also managed to determine sensitive needling points for the pain shock. Conclusion:Following results were obtained from 3 patients with the pain shock caused by Korean bee-venom therapy from July 2001 to September 2001. 1. Either positive or negative responses were shown after the pain shock. For case 1, extreme pain was accompanied with muscular convulsion and tremble, ocular hyperemia, delirium, stiffening of extremities, and hyper ventilation which all suggest positive responses. For case 2 and 3, extreme pain was accompanied with facial sweating, asthenia of extremities, pallor face, dizziness, weak voice, and sleepiness which are the signs of negative responses. 2. The time required to recover to stable state took nearly an hour (including sleeping time and there was no side effect. 3. Precautions required to prevent the pain shock includes full concentration from the practitioner, accurate point

Conflicting reports on prevalence of RLS exist in Asian countries due to differences in sampling strategies and assessment instruments. We assessed the prevalence, correlates, quality of life, and psychiatric comorbidity of RLS in South Korea. Cross-sectional nationwide survey. Nationally representative sample of 6,509 Korean adults aged 18-64. Face-to-face interviews based on the Korean translation of the four features of RLS defined by the International RLS Study Group (IRLSSG), the Korean version of Composite International Diagnostic Interview (K-CIDI), and EuroQol (EQ-5D) were conducted for all participants. The weighted prevalence of RLS in South Korea was 0.9% (men, 0.6%; women, 1.3%). Subjects with RLS had a lower quality of life according to EQ-5D than those without RLS. Adjusted odds ratio for lifetime diagnosis of DSM-IV major depressive disorder (2.57, 95% confidence interval [1.33, 4.96]), panic disorder (18.9 [4.72, 75.9]) and posttraumatic stress disorder (3.76 [1.32, 10.7]) suggest strong association between RLS and DSM-IV depression and anxiety disorders. Prevalence of RLS estimated based on the IRLSSG diagnostic criteria is substantially lower in South Korea than in Western countries. Differences in culture and risk factors that affect the expression of RLS may vary across the countries.

Cumulative evidence suggests that coffee consumption may have beneficial effects on metabolic diseases; however, few previous studies have considered the types of coffee consumed and the additives used. We investigated the relationship between coffee consumption and metabolic syndrome (MetSyn) and its components. We analyzed 17,953 Korean adults, aged 19-65 years, using cross-sectional data from the Korean National Health and Nutrition Examination Survey (KNHANES, 2007-2011). Coffee consumption level, types of coffee consumed, and the additives used were assessed based on a food frequency questionnaire and 24-h recall. Demographic and lifestyle factors were assessed using self-administered questionnaires. Data on metabolic biomarkers were obtained from a health examination. Multivariable logistic regression was used to determine the odds ratios of prevalent metabolic syndrome and its components according to frequency and type of coffee consumption. We found that 76% of the subjects were habitual coffee drinkers, most of whom consumed instant coffee mix containing sugar and powder creamer. After multivariable adjustment, the odds ratios (95% CI) comparing those who consumed coffee ≥3 times/day with those who consumed coffee <1 time/week were 1.37 (1.15-1.63) for obesity, 1.33 (1.11-1.59) for abdominal obesity, 1.28 (1.09-1.51) for hypo-HDL cholesterolemia, and 1.37 (1.10-1.72) for metabolic syndrome. Instant-coffee drinkers were observed to have elevated risks of these metabolic conditions. Consumption of coffee, particularly instant coffee mix, may have harmful effects on MetSyn, perhaps partly deriving from excessive intake of sugar and powder creamer.

This study aimed at looking at perception of English palatal codas by Korean speakers of English to determine if perception problems are the source of production problems. In particular, first, this study looked at the possible first language effect on the perception of English palatal codas. Second, a possible perceptual source of vowel epenthesis after English palatal codas was investigated. In addition, individual factors, such as length of residence, TOEFL score, gender and academic status, were compared to determine if those affected the varying degree of the perception accuracy. Eleven adult Korean speakers of English as well as three native speakers of English participated in the study. Three sets of a perception test including identification of minimally different English pseudo- or real words were carried out. The results showed that, first, the Korean speakers perceived the English codas significantly worse than the Americans. Second, the study supported the idea that Koreans perceived an extra /i/ after the final affricates due to final release. Finally, none of the individual factors explained the varying degree of the perceptional accuracy. In particular, TOEFL scores and the perception test scores did not have any statistically significant association.

To explore perceptions and experiences of patients with chronic fatigue with traditional Korean medicine (TKM) and their motivation for choosing TKM. Qualitative, one-on-one, in-depth interview study. Primary TKM hospitals in Seoul, Incheon and Daejeon, South Korea. 15 patients with chronic fatigue were interviewed in this study. Patients with chronic fatigue experienced physical and psychological symptoms that resulted in severe difficulties associated with routine daily activities. The motivations for choosing TKM were primarily dissatisfaction with conventional medicine and previous positive experiences with TKM. While undergoing TKM treatment, patients found that TKM practitioners considered fatigue to be a treatable illness; also, patients felt comfortable with the doctor-patient relationship in TKM. Healthcare providers need to be concerned about the symptoms of chronic fatigue to a degree that is in line with the patient's own perceptions. Korean patients with chronic fatigue choose TKM as an alternative to fulfil their long-term needs that were unmet by conventional medicine, and they are greatly positively influenced by TKM. TKM may present a possible therapy to alleviate symptoms of diseases that conventional medicine does not address and is an approach that has a considerable effect on Korean patients.

It is difficult to apply the proper intensity of statin for new treatment guidelines in clinical settings because of few data about the statin efficacy in Asians. We conducted a retrospective, observational study to estimate the percentage changes in lipid parameters and glucose induced by different statins. We analyzed 3854 patients including those with nondiabetes and diabetes treated at the outpatient clinic between 2003 and 2013 who were statin-naïve and maintained fixed-dose of statin for at least 18 months. Moderate- and low-intensity statin therapy was effective in reducing low-density lipoprotein cholesterol (LDL-C) to statin group. The effects of statins in elevating high-density lipoprotein cholesterol were similar in each statin groups, except the ezetimibe-simvastatin group (4.5 ± 2.1%) and high-dose atorvastatin groups (9.7 ± 3.3% and 8.7 ± 2.4% for 40 mg and 80 mg of atorvastatin/day, respectively). High-density lipoprotein cholesterol increased less and LDL-C decreased more in diabetes than in nondiabetes. There were no significant changes of fasting glucose after statin use in nondiabetic patients. Moderate- or low-intensity statin was effective enough in reaching National Cholesterol Education Program Adult Treatment Panel III LDL-C target goals in Koreans. Low-intensity statin showed around 30% LDL-C reduction from the baseline level in Koreans, which is comparable to moderate-intensity statin in new guideline.

Dietary sodium intake is considered one of the major causal factors for hypertension. Thus, to control the increase of blood pressure and reduce the risk of hypertension-related clinical complications, a reduction in sodium intake is recommended. The present study aimed at determining the association of dietary sodium intake with meal and snack frequency, snacking time, and taste preference in Korean young adults aged 20-26 years, using a 125-item dish-frequency questionnaire. The mean dietary sodium intakes of men and women were 270.6 mmol/day and 213.1 mmol/day, which were approximately 310% and 245% of the daily sodium intake goal for Korean men and women, respectively. Dietary sodium intake was positively correlated with systolic blood pressure in the total group, and BMI in the total and men-only groups. In the total and men-only groups, those who consumed meals more times per day consumed more dietary sodium, but the number of times they consumed snacks was negatively correlated with dietary sodium intake in the total, men-only, and women-only groups. In addition, those who consumed snacks in the evening consumed more sodium than those who did so in the morning in the men-only group. The sodium intake was also positively associated with preference for salty and sweet taste in the total and women-only groups. Such a high intake of sodium in these young subjects shows that a reduction in sodium intake is important for the prevention of hypertension and related diseases in the future.

Cigarette smoking is a preventable risk factor that contributes to unnecessary lung cancer burden among Korean Americans and there is limited research on effective smoking cessation strategies for this population. Smartphone-based smoking cessation apps that leverage just-in-time adaptive interventions (JITAIs) hold promise for smokers attempting to quit. However, little is known about how to develop and tailor a smoking cessation JITAI for Korean American emerging adult (KAEA) smokers. This paper documents the development process of MyQuit USC according to design guidelines for JITAI. Our development process builds on findings from a prior ecological momentary assessment study by using qualitative research methods. Semi-structured interviews and a focus group were conducted to inform which intervention options to offer and the decision rules that dictate their delivery. Qualitative findings highlighted that (1) smoking episodes are highly context-driven and that (2) KAEA smokers believe they need personalized cessation strategies tailored to different contexts. Thus, MyQuit USC operates via decision rules that guide the delivery of personalized implementation intentions, which are contingent on dynamic factors, to be delivered "just in time" at user-scheduled, high-risk smoking situations. Through an iterative design process, informed by quantitative and qualitative formative research, we developed a smoking cessation JITAI tailored specifically for KAEA smokers. Further testing is under way to optimize future versions of the app with the most effective intervention strategies and decision rules. MyQuit USC has the potential to provide cessation support in real-world settings, when KAEAs need them the most.

Full Text Available Abstracts Background Standardized Korean red ginseng extract has become the best-selling influenza-like illness (ILI remedy in Korea, yet much controversy regarding the efficacy of the Korean red ginseng (KRG in reducing ILI incidence remains. The aim of the study is to assess the efficacy of the KRG extract on the ILI incidence in healthy adults. Methods/Design We will conduct a randomized, double-blind, placebo-controlled study at the onset of the influenza seasons. A total of 100 subjects 30-70 years of age will be recruited from the general populations. The subjects will be instructed to take 9 capsules per day of either the KRG extract or a placebo for a period of 3 months. The primary outcome measure is to assess the frequency of ILI onset in participated subjects. Secondary variable measures will be included severity and duration of ILI symptoms. The ILI symptoms will be scored by subjects using a 4-point scale. Discussion This study is a randomized placebo controlled trial to evaluate the efficacy of the KRG extract compared to placebo and will be provided valuable new information about the clinical and physiological effects of the KRG extract on reduction of ILI incidence including flu and upper respiratory tract infections. The study has been pragmatically designed to ensure that the study findings can be implemented into clinical practice if KRG extract can be shown to be an effective reduction strategy in ILI incidence.

Nasalance is used to evaluate the velopharyngeal incompetence in clinical diagnoses using a nasometer. The aim of this study is to find the nasalance differences between Vietnamese cleft palate children and Korean cleft palate children by measuring the nasalance of five oral vowels. Ten Vietnamese cleft palate children after surgery, three Vietnamese children for the control group, and ten Korean cleft palate children after surgery with the same age participated in this experimentation. Instead of Korean control, the standard value of Korean version of the simplified nasometric assessment procedures (kSNAP) was used. The results are as follows: (1) the highest nasalance score among the Vietnamese normal vowels is the low vowel /a/; however, that of Korean normal vowels is the high vowel /i/. (2) The average nasalance score of Korean cleft palate vowels is 18% higher than that of Vietnamese cleft palate vowels. There was a nasalance score of over 45% among the vowels /e/ and /i/ in Vietnamese cleft palate patients and /i/, /o/, and /u/ in Korean cleft palate patients. These different nasalance scores of the same vowels seem to cause an ethnic difference between Vietnamese and Korean cleft palate children.

Blood mercury and urinary arsenic levels are more than fivefold greater in the Korean population compared with those of the United States. This may be related to the foods people consumed. Therefore, we examined the associations between food categories and mercury and arsenic exposure in the Korean adult population. Data regarding nutritional, biochemical, and health-related parameters were obtained from a cross-sectional study, the 2008-2009 Korean National Health and Nutrition Examination Survey (3,404 men and women age ≥ 20 years). The log-transformed blood mercury and urinary arsenic levels were regressed against the frequency tertiles of each food group after covariate adjustment for sex, age, residence area, education level, smoking status, and drinking status using food-frequency data. Blood mercury levels in the high consumption groups compared to the low consumption groups were elevated by about 20 percents with salted fish, shellfish, whitefish, bluefish, and alcohol, and by about 9-14 percents with seaweeds, green vegetables, fruits and tea, whereas rice did not affect blood mercury levels. Urinary arsenic levels were markedly increased with consumption of rice, bluefish, salted fish, shellfish, whitefish, and seaweed, whereas they were moderately increased with consumption of grains, green and white vegetables, fruits, coffee, and alcohol. The remaining food categories tended to lower these levels only minimally. In conclusion, the typical Asian diet, which is high in rice, salted fish, shellfish, vegetables, alcoholic beverages, and tea, may be associated with greater blood mercury and urinary arsenic levels. This study suggests that mercury and arsenic contents should be monitored and controlled in soil and water used for agriculture to decrease health risks from heavy-metal contamination.

To investigate the impact of different living arrangements on quality of life (QoL) and health-related quality of life (HRQoL) in the elderly. We used data from the first to fourth wave of the Korean Longitudinal Study of Aging. Using the first wave as a baseline, the data included 5050 individuals aged 60 years and older with at least one living child. QoL and HRQoL were measured using a visual analogue scale developed by the Korean Labor Institute that bears similarity to the EQ-VAS. Living arrangements were categorized based on household composition (single household, one-generation household, two-generation household, and three-generation household) and the marital status of a cohabiting adult child. A generalized estimating equation was used to examine the association between living arrangements and QoL/HRQoL. Compared to elderly individuals living in three-generation families with a married child, those in a single household (QoL: β = -2.67 [P = 0.001]; HRQoL: β = -2.24 [P = 0.007]), those living in a three-generation family with an unmarried adult child (QoL: β = -5.19 [P living in a two-generation family with an unmarried adult child (QoL: β = -2.88 [P living alone, but also for those living with an unmarried adult child; elderly persons who are female and part of the lowest equivalent household income group must receive particular attention.

Evaluation of the Janus kinase 2 (JAK2) V617F mutation has been widely used for the diagnosis of myeloproliferative neoplasms (MPN). However, its prognostic relevance to clinical outcome is not completely understood. We investigated the association of JAK2 V617F with vascular events in Korean patients with myeloproliferative neoplasms (MPN). We studied 283 patients from 15 centers, who were diagnosed with MPN. The JAK2 V617F status was evaluated by allele-specific polymerase chain reaction (PCR) and sequencing. The patients' diagnoses were essential thrombocythemia (ET n = 146), polycythemia vera (PV n = 120), primary myelofibrosis (n = 12), and unclassifiable MPN (MPNu n = 5). JAK2 V617F was detected in 89 (61%) patients with ET, 103 (86%) with PV, four (33%) with myelofibrosis, and four (80%) with MPNu. A higher number of leukocytes, haemoglobin levels and BM cellularity as well as an older age, lower platelet counts, and diagnosis of PV were significantly correlated with JAK2 V617F. Eighty-three and 43 episodes of thrombosis and bleeding occurred in 100 patients each before and after the diagnosis. Vascular events more frequently occurred in 37% of patients with JAK2 V617F than in 29% of those without the mutation (p = 0.045). Among 175 patients whose samples were available for sequencing, 28 patients with homozygous JAK2 V617F had vascular events more frequently (57%) than those who were heterozygotes (39%) or had the wild type (27%) (p = 0.03). The multivariate analysis showed that a JAK2 homozygous mutation, hypercholesterolemia and older age were independent risk factors for a vascular event. The results of this study showed that Korean patients with MPN had a similar JAK2 mutation rate and frequency of vascular events when compared to Western patients. The presence of V617F was significantly related to vascular events. Therefore, initial evaluation for the JAK2 mutation and careful monitoring for vascular events should be performed in MPN patients.

Inverse relationship between fat intake and blood lead levels in the Korean adult population in the KNHANES 2007-2009.

Blood lead levels (BLLs) in the Korean adult population are about twofold higher than those in the US adult population, which may be related to nutrient intake. We examined which nutritional factors might be associated with decreased BLL. This study was based on Korean National Health and Nutrition Examination Survey data obtained over 3 years (2007-2009) using a rolling sampling design involving a complex, stratified, multistage, probability-cluster survey of a representative sample of the non-institutionalized civilian population of South Korea. A multiple regression analysis after controlling for covariates indicated that dietary fat and protein were significant opposite predictors of BLL in five different models; fat and protein intake had negative and positive associations with BLL, respectively. Covariates used in the analysis were sex, age, regional area, education level, smoking and drinking status, hypertension, use of antihypertensive drugs, diabetes, use of antidiabetic drugs, use of cholesterol-lowering drugs, hemoglobin level, and exposure to chemical substances during daily life. Intake levels of other nutrients, such as dietary fiber, carbohydrates, and calcium, did not show any significant effect on BLL. Gender was also an important predictor: BLL was significantly higher in men than women. However, total femur T-score, which represents bone mass, was unaffected by BLL. When calculating adjusted predicted marginal values of blood lead according to dietary fat percentage, BLL was lower by 5.3% and 8.0% in men when fat intake was increased from 10% to 20% and 25%, respectively. This effect of fat intake on BLL was minimal in women. The accumulation of body stores of lead from lead exposure may be reduced by increasing dietary fat consumption to 25% of energy intake, especially in men. However, this must be weighed against possible cardiovascular risks of higher fat diets. Copyright © 2012 Elsevier B.V. All rights reserved.

Despite compelling evidence showing that social networks and social support are associated with depression, relatively little research is available on this topic for older Koreans at high risk of depression. This article aimed to examine the relationship among different types of social networks (family vs. friends), social support (instrumental vs. emotional), and perceived general health among older Koreans at high risk of depression. We would then test for possible differences in pathways between two age groups (60-74 years vs. 75 years and older). Using data from the 2008 Survey of Elderly Life and Welfare Need, age 60-74 years (n = 2,815) and age 75 years and older (n = 1,784) were analyzed separately. Path analyses were used to examine the relationships among social network, support, and health among Korean older adults at high risk of depression. Findings highlighted the complex associations among social networks, social support, and perceived general health within old age. Moreover, this study called attention to the negative association between instrumental support from family networks and perceived general health among older Koreans aged 60-74 years at high risk of depression. The work discussed in this article would help inform the design of much needed and effective social intervention programs for the growing number of Korean older adults with depression.

Full Text Available Abstract Background The benefits of physical activity on physical and mental health are well known. The accessibility of sports facilities is reported to have considerable association with the amount of physical activity a person participates in. Therefore, we investigated the association between subjectively assessed accessibility of sports facilities and physical activity among Korean adults. Methods We obtained data from the 2012 Community Health Survey. Physical activity was measured based on weekly metabolic equivalent task (MET hours according to the International Physical Activity Questionnaire (IPAQ. Sociodemographic, economic, and health variables were used as covariates in a logistic regression model. Results A total 201,723 participants were included in this study. Participants with easy access to sports facilities participated in physical activity more often than those without easy access (OR = 1.16, 95 % CI 1.13–1.20. More physical activity was generally observed if participants had a history of depression or if participants were among the white-collar or urban subgroups. Conclusion Our results showed that the accessibility of sports facilities is associated with physical activity. Therefore, it is crucial to consider the accessibility of sports facilities when promoting an environment conducive to physical activity or designing programs for enhancing physical activity.

This study explored the psychometric qualities and construct validity of the Spiritual Well-Being Scale (SWBS; Ellison in J Psychol Theol 11:330-340, 1983) using a sample of 470 Korean adults. Two factor analyses, exploratory factor analysis and confirmatory factor analysis, were conducted in order to test the validity of the SWBS. The results of the factor analyses supported the original two-dimensional structure of the SWBS-religious well-being (RWB) and existential well-being (EWB) with method effects associated with negatively worded items. By controlling for method effects, the evaluation of the two-factor structure of SWBS is confirmed with clarity. Further, the differential pattern and magnitude of correlations between the SWB subscales and the religious and psychological variables suggested that two factors of the SWBS were valid for Protestant, Catholic, and religiously unaffiliated groups except Buddhists. The Protestant group scored higher in RWB compared to the Buddhist, Catholic, and unaffiliated groups. The Protestant group scored higher in EWB compared to the unaffiliated groups. Future studies may need to include more Buddhist samples to gain solid evidence for validity of the SWBS on a non-Western religious tradition.

To evaluate therapeutic outcomes of interferon alpha-2a (IFNα2a) treatment in patients with Behcet's disease who were refractory to immunosuppressive agents. This retrospective case series reviewed the medical records of 5 patients with refractory Behcet uveitis from January 2011 to February 2017. IFNα2a was administered at a dose of 3 million IU 3 times per week. Clinical response, relapse rate, and change of visual acuity were evaluated. The mean age of patients was 39.60 ± 9.21 years, and the median treatment duration was 6 months. Four of the 5 patients (80%) presented with responses to IFNα2a without any uveitis attack during the treatment period. The mean number of uveitis attacks/year per patient during the treatment was 0.40 ± 0.89. The mean log of the Minimum Angle of Resolution visual acuity improved from 1.44 ± 0.38 at baseline to 1.02 ± 0.58 at the final follow up. IFNα2a is an effective therapy for Behcet uveitis refractory to conventional immunosuppressants in Korean patients.

The primary objective of this study was to analyze the hard and soft tissue profile and comparison of the both sexes in Korean adults using roentgenocephalometry. The subjects were 122 males and 116 females from 18 to 22 years of age selected on the basis of their excellent occlusion and harmonious profile. It was an investigation about the interrelationships in the angles which consisted of Frankfort horizontal plane (FH plane), Sella Nasion plane (SN plane), Nasal floor plane (NF plane) and Mandibular plane (Md plane) as reference planes, and of the axial inclinations of the upper anterior tooth to Nasal floor plane (NF Plane) and of the lower anterior tooth to Mandibular plane (Md Plane). Among the 14 categories established on the soft tissue landmarks, the 6 categories were studied for the relationship to Frankfort horizontal plane (FH Plane), and the 8 categories were studied for the soft tissue contour. The results were as follows: 1. Among 8 measured angles in the hard tissue, the angle of FH-Md, NF-Md and N-Md were greater in females than in males. 2. The axial inclinations of the anterior teeth to NF Plane and Md plane were slightly greater in males than in females. 3. Among 14 measured angles in the soft tissue, the angles of G-Sn-P and E-Pog-Sn were greater in males, and FH-G-Sn, G·Sn-Sn·Pog and Pog-Sn-P were greater in females. 4. In males, the variability of measured values in both lips region were high.

To investigate nurses' opinions and practices of providing information in a global context through cultural comparison. Providing sufficient information to patients about nursing interventions and plans is essential for patient-centred care. While many countries have specific legislation making information delivery to patients a legal duty of nurses, no such legislation exists in both the Republic of Korea and Italy; nurses' only guidance is the deontological code. This was a cross-sectional survey study involving a convenience sample of 174 Korean nurses and 121 Italian nurses working in internal medicine and surgery at university hospitals. Data were collected using a self-administered questionnaire between February and November 2014. The questionnaire assessed demographic and professional characteristics, and difficulties and practices regarding information provision. Korean and Italian nurses significantly differed in all demographic and professional characteristics. More Korean than Italian participants reported that their role in providing information was well explained within their teams, but both groups reported the same level and type of difficulties in delivering information. Nurses in both countries regularly informed patients about medications and nursing procedures, but provided information about nursing care plans less frequently. Few nurses frequently provided information to relatives instead of patients. Despite cultural, demographic and professional differences between Korean and Italian nurses, their difficulties and practices in information delivery to patient were similar. Hospital managers and policymakers should be aware that nurse-patient communication can be impaired by organizational factors, patient characteristics or the interaction among providers. Educational interventions and strategies are needed to increase information provision to patients about nursing care plans. © 2017 International Council of Nurses.

The 2011 Knee Society Score © (2011 KS Score © ) is used to characterize the expectations, symptoms, physical activity, and satisfaction of patients who undergo TKA and is widely used to assess the outcome of TKA. However, it has not been adapted or validated for use in Korea. We developed a Korean version of the 2011 KS Score and evaluated the (1) test-retest reliability, (2) convergent validity, and (3) responsiveness of the Korean version. The Korean version of the 2011 KS Score was derived by using a well-established translational procedure based on international guidelines, which include translation, synthesis, back-translation, expert committee review, pretesting, and submission for appraisal. A total of 123 patients with knee osteoarthritis who were scheduled to undergo TKA were recruited for the study. Ninety percent of the patients (111 of 123) were women, which is an exact representation of the Korean population having TKAs. To evaluate reliability, the patients were evaluated twice during a 4-week interval using the questionnaire. Reliability was assessed by using intraclass correlation coefficients (ICCs) and internal consistency by using Cronbach's alpha to determine the validity of the Korean version of the 2011 KS Score. The patients were evaluated by using the validated Korean versions of the WOMAC and SF-36 questionnaires. Spearman's correlation coefficient was used for validation. Responsiveness was determined by calculating the standardized response mean from the preoperative and postoperative test scores in the Korean version of the 2011 KS Score. To address the gender disparity in our study we identified 53 males who underwent TKA for osteoarthritis after completion of this study and generated age-matched controlled groups to evaluate construct validity and responsiveness in Korean males. The reliability proved good to excellent with an ICC between 0.69 and 0.85, depending on the clinical properties tested, which included the following

Despite the efforts of the World Anti-Doping Agency and national anti-doping agencies at the international level, a relatively low and steady rate of positive doping tests still persists all over the world. Evidence on adolescents using doping substances exists, and the proportion of adolescents engaging in doping practices is small but significant. In relation to the international research trends on anti-doping, this study aims to evaluate doping knowledge, practices, and attitudes among Korean adult and adolescent elite athletes to provide effective information on anti-doping policies and education programs. This study was a cross-sectional study of 454 Korean elite athletes (249 adults in 23 events and 205 adolescents in 22 events). Data were collected by an interviewer-administered questionnaire containing items regarding doping practices and knowledge, brief definitions of performance-enhancing substances/methods and recreational substances, and the Performance Enhancement Attitude Scale (PEAS). Adolescent (47.3%) and adult (57.0%) athletes received information on banned substances of their respective sports from the Korea Anti-Doping Agency, and 39.0 and 53.4% of adolescents and adults, respectively, had knowledge of banned substances and had permissive attitudes toward doping compared to those who were unaware. Adolescent and adult athletes have inadvertently (1.5 and 3.6%, respectively) or knowingly (1.0 and 2.8%, respectively) taken banned performance-enhancing substances, and 2.4 and 3.2%, respectively, knew someone who had taken banned substances. And the adolescent athletes in motor skill category (PEAS: 40.24 ± 10.91) were more permissive toward doping than those in team category (PEAS: 35.08 ± 10.21). An in-depth anti-doping education for Korean athletes should be more widely implemented, and effective anti-doping policy should meet the athletes' demographic characteristics, personalities, and values.

2001-10-01

Nursing theory provides a systematic explanation and description of nursing phenomena. Western nursing theories have widely influenced Korean nursing. And yet, although nursing theory has universal aspects, the differences in philosophy and culture that are unique to each country need to be considered. This inquiry seeks to investigate the Korean cultural heritage, which integrates Confucianism, Buddhism, and Taoism, and how it provides a unique worldview of human beings, the universe, health, and nursing. Essential principles and therapies consistent with Taoist philosophy are also identified. This framework is proffered as the basis for establishing understanding between Korean nurses and patients.

In Korea, cancer is one of the most important causes of death. Cancer patients have sought alternative methods, like complementary and alternative medicine (CAM) together with Western medicine, to treat cancer. Also, there are many kinds of providers of CAM therapy, including providers of Korean oriental medicine therapy. The purpose of this study is to identify the behaviors of Korean oriental medicine therapy and CAM therapy providers who treat cancer patients and to provide background knowledge for establishing a new policy with the management and quality control of CAM. Structured and well organized questionnaires were made, and 350 persons were surveyed concerning the providers of CAM or Korean oriental medicine. The questionnaires were collected and analyzed. The questionnaires (182) were collected. The questionnaires identified a total of 73 known providers, such as medicinal professionals or other providers of CAM suppliers, 35.6% of whom had had experience with treating cancer patients (52.6% vs. 29.6%). The treatment methods were a little different: alternative therapy and nutritional therapy being preferred by medicinal professionals and mind body modulation therapy and alternative therapy being preferred by other CAM providers. Four patients (7.4%) experienced side effects, and 6 patients (12.5%) experienced legal problems. As the method for managing the therapy, CAM providers, medicinal professionals, and other CAM providers had different viewpoints. For example, some CAM providers stated that both legislation and an official education on CAM or a national examination were needed as a first step to establish the provider's qualifications and that as a second step, a license test was needed for quality control. To the contrary, medicinal professionals stated that a license test was needed before legislation. Adequate management and quality control of CAM providers is thought to involve both education and legislation.

X-ray exposure should be clinically justified and each exposure should be expected to give patients benefits. Since dental radiographic examination is one of the most frequent radiological procedures, radiation hazard becomes an important public health concern. The purpose of this study was to investigate the attitude of Korean dentists about radiation safety and use of criteria for selecting the frequency and type of radiographic examinations. The study included 267 Korean dentists. Five questions related to radiation safety were asked of each of them. These questions were about factors associated with radiation protection of patients and operators including the use of radiographic selection criteria for intraoral radiographic procedures. The frequency of prescription of routine radiographic examination (an example is a panoramic radiograph for screening process for occult disease) was 34.1%, while that of selective radiography was 64.0%. Dentists' discussion of radiation risk and benefit with patients was infrequent. More than half of the operators held the image receptor by themselves during intraoral radiographic examinations. Lead apron/thyroid collars for patient protection were used by fewer than 22% of dental offices. Rectangular collimation was utilized by fewer than 15% of dental offices. The majority of Korean dentists in the study did not practice radiation protection procedures which would be required to minimize exposure to unnecessary radiation for patients and dental professionals. Mandatory continuing professional education in radiation safety and development of Korean radiographic selection criteria is recommended.

2009-01-01

While literature on elder abuse has expanded, elder abuse by intimate partners has been less investigated. Even less is known about intimate partner violence among older Koreans living in North America. This article identifies important cultural considerations for individuals helping the Korean older adult community, beginning with the definition of intimate partner violence in this community and barriers to leaving that include traditional views of the East Asian self. Current practice interventions are discussed and recommendations for future practice such as healing han, the accumulated suffering from years of abuse, are suggested. The ultimate goal of this paper is to expand awareness in order to develop the best culturally competent prevention and intervention practice for Korean older intimate partner violence survivors in North America.

We developed an adverse events (AEs) reporting form for Korean folk medicine. The first version of the form was developed and tested in the clinical setting for spontaneous reporting of AEs. Additional revisions to the reporting form were made based on collected data and expert input. We developed an AEs reporting form for Korean folk medicine. The items of this form were based on patient information, folk medicine properties, and AEs. For causality assessment, folk medicine properties such as classification, common and vernacular names, scientific name, part used, harvesting time, storage conditions, purchasing route, product licensing, prescription, persons with similar exposure, any remnant of raw natural products collected from the patient, and cautions or contraindications were added. This is the first reporting form for AEs that incorporates important characteristics of Korean folk medicine. This form would have an important role in reporting adverse events for Korean folk medicine. © 2016 The Authors.

Postural instability and gait disturbance are the cardinal symptoms associated with falling among patients with Parkinson's disease (PD). The Tinetti mobility test (TMT) is a well-established measurement tool used to predict falls among elderly people. However, the TMT has not been established or widely used among PD patients in Korea. The purpose of this study was to evaluate the reliability and validity of the Korean version of the TMT for PD patients. Twenty-four patients diagnosed with PD were enrolled in this study. For the interrater reliability test, thirteen clinicians scored the TMT after watching a video clip. We also used the test-retest method to determine intrarater reliability. For concurrent validation, the unified Parkinson's disease rating scale, Hoehn and Yahr staging, Berg Balance Scale, Timed-Up and Go test, 10-m walk test, and gait analysis by three-dimensional motion capture were also used. We analyzed receiver operating characteristic curve to predict falling. The interrater reliability and intrarater reliability of the Korean Tinetti balance scale were 0.97 and 0.98, respectively. The interrater reliability and intra-rater reliability of the Korean Tinetti gait scale were 0.94 and 0.96, respectively. The Korean TMT scores were significantly correlated with the other clinical scales and three-dimensional motion capture. The cutoff values for predicting falling were 14 points (balance subscale) and 10 points (gait subscale). We found that the Korean version of the TMT showed excellent validity and reliability for gait and balance and had high sensitivity and specificity for predicting falls among patients with PD.

We aimed to validate the Inventory of Complicated Grief (ICG)-Korean version among 1,138 Korean adolescents, representing a response rate of 57% of 1,997 students. Participants completed a set of questionnaires including demographic variables (age, sex, years of education, experience of grief), the ICG, the Children's Depression Inventory (CDI) and the Lifetime Incidence of Traumatic Events-Child (LITE-C). Exploratory factor analysis was performed to determine whether the ICG items indicated complicated grief in Korean adolescents. The internal consistency of the ICG-Korean version was Cronbach's α=0.87. The test-retest reliability for a randomly selected sample of 314 participants in 2 weeks was r=0.75 (PKaiser-Meyer-Olkin Measure of Sampling Adequacy=0.911; Bartlett's Test of Sphericity, χ(2)=13,144.7, P<0.001). After omission of 3 items, the value of Cronbach's α increased from 0.87 for the 19-item ICG-Korean version to 0.93 for the 16-item ICG-Korean version. These results suggest that the ICG is a useful tool in assessing for complicated grief in Korean adolescents. However, the 16-item version of the ICG appeared to be more valid compared to the 19-item version of the ICG. We suggest that the 16-item version of the ICG be used to screen for complicated grief in Korean adolescents.

Previous epidemiologic studies have revealed that East-Asian populations experience fewer depressive symptoms than American populations do. However, it is unclear whether this difference applies to clinical patients with major depressive disorder (MDD). This present study included 1592 Korean and 3744 American outpatients who were 18 years of age or older and met the Diagnostic and Statistical Manual of Mental Disorders, 4th ed. criteria for single or recurrent episodes of nonpsychotic MDD, and evaluated their symptoms of depression using the Hamilton Depression Rating Scale and the Quality of Life Enjoyment and Satisfaction Questionnaire Short Form. Korean patients scored significantly lower for guilt and depressed mood items, and higher for hypochondriasis and suicidality items than American patients did, after adjusting for total Hamilton Depression Rating Scale scores. Conversely, no significant differences were found in quality and function of daily life between groups. Multivariate logistic regression analyses revealed that Korean patients experienced less frequent depressed mood and guilt, including verbal and nonverbal expression of depressed mood [adjusted odds ratio (AOR) = 0.14, 95% confidence interval (CI) 0.08-0.23] and feelings of punishment (AOR = 0.036, 95% CI 0.025-0.054) when compared with Americans after adjusting for age and sex. Conversely, Korean patients experienced more frequent suicidality and hypochondriasis, including suicidal ideas or gestures (AOR = 2.10, 95% CI 1.60-2.76) and self-absorption of hypochondriasis (AOR = 1.94, 95% CI 1.70-2.20). In conclusion, decreased expression of depressed mood and guilt may cause underdiagnosis of MDD in Korean patients. Early diagnosis of and intervention for depression and suicide may be delayed because of this specific cross-cultural difference in depression symptoms.

2018-01-01

Male factor subfertility has increasingly been considered the cause of infertility in couples. Many men with male infertility have sperm problems such as oligozoospermia, asthenozoospermia, or teratozoospermia. Because abnormal semen parameters are idiopathic to some extent, no standard therapy has been established to date. Herbal medicine has been reported to have beneficial properties in the treatment of subfertility, especially in improving semen quality both in vivo and in human studies. Therefore, we intend to investigate the effectiveness and safety of treatment using Korean medicine (KM) for infertile male patients with poor semen quality.This will be a single-center, prospective, case-only observational pilot study. About 20 male patients with infertility who visit Conmaul Hospital of Korean Medicine will be recruited. We will follow the standard treatment protocol, which has shown good results in the treatment of male infertility. The protocol is composed mainly of a 10-week herbal decoction treatment; acupuncture and/or pharmacopuncture are added when needed. Semen samples, quality of life, and the scrotal temperatures of infertile men will be observed before and after the 10-week treatment with KM.The study has received ethical approval from the Public Institutional Review Board (approval number: P01-201708-21-008). The findings will be disseminated to appropriate audiences via peer-reviewed publication and conference presentations. Korean Clinical Trial Registry (CRIS), Republic of Korea: KCT0002611.

Patients with cognitive impairment have decreased lower limb function. Therefore, we aimed to investigate the relationship between lower limb function and cognitive disorders to determine whether lower limb function can be screened to identify cognitive decline. Using Korean National Health Insurance Service-National Sample Cohort database data, we assessed the cognitive and lower limb functioning of 66-year-olds who underwent national health screening between 2010 and 2014. Cognitive function was assessed via a questionnaire. Timed Up-and-Go (TUG) and one-leg-standing (OLS) tests were performed to evaluate lower limb function. Associations between cognitive and lower limb functions were analyzed, and optimal cut-off points for these tests to screen for cognitive decline, were determined. Cognitive function was significantly correlated with TUG interval ( r = 0.414, p cognitive disorders were >11 s and ≤12 s for TUG interval and OLS duration, respectively. Among 66-year-olds who underwent national health screening, a significant correlation between lower limb and cognitive function was demonstrated. The TUG and OLS tests are useful screening tools for cognitive disorders in elderly patients. A large-scale prospective cohort study should be conducted to investigate the causal relationship between cognitive and lower limb function.

Few studies have examined overall patterns of eating alone in relation to the risk of metabolic syndrome (MetS) in Korean populations. The present study aimed to examine the relationship between patterns of eating alone and the risk of MetS in Korean adults. Data from the Korea National Health and Nutrition Examination Survey (KNHANES) for 2013⁻2015 were used, with 8988 Korean adult participants, including 3624 men and 5364 women, aged 18 to 64 years. Patterns of eating alone were categorized into eight groups based on the total frequency of eating alone on a daily basis in the past one year: (1) three times for breakfast, lunch, and dinner; (2) twice for breakfast and dinner; (3) twice for lunch and dinner; (4) twice for breakfast and lunch; (5) once for breakfast only; (6) once for lunch only; (7) once for dinner only; and (8) never eating alone. The presence of MetS has been defined by the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) and International Diabetes Federation (IDF). Multivariable logistic regression analyses were performed to assess the association between patterns of eating alone versus the risk of MetS after controlling for age, income, occupation, number of family members, generation types, marital status, smoking status, and physical activity. The prevalence of MetS was the highest in men and women aged 40⁻64 who had breakfast, lunch, and dinner alone (50.1% and 36.8%, respectively). Men who had dinner alone or lunch and dinner alone compared with those who eat with others had a significantly higher risk of MetS, with adjusted odds ratios (AOR) of 1.51, and a 95% confidence interval (CI) of 1.06⁻2.16; and an AOR of 1.54, with a 95% CI of 1.05⁻2.25, respectively. Women who had breakfast alone compared with those who ate with others had a significantly lower risk of MetS (AOR 0.70, 95% CI 0.53⁻0.94). In conclusion, patterns of eating alone are differentially associated with the risk of MetS in a

This study examined the gender-specific associations between cohabitation with parents and stress using an econometric approach. A total of 13,565 (41.7% men and 58.3% women) Korean adults aged 20-59 years from the Korean National Health and Nutrition Examination Survey (KNHANES) 2008 to 2011 were pooled. They reported their gender, age, marital status, education level, employment status, income, home ownership, and cohabitation status with their parents. The association of living with parents and stress, as well as the gender difference in the association, was investigated using propensity score matching and the average treatment effect on the treated. Adults with higher education and income, not owning a house, or living in larger cities were less likely to live with parents. Stress was associated with having children and participating in the labor market for both married men and women. Moreover, living with parents was a protective factor for stress among husbands, but a risk factor for wives in Korea. Gender differences existed in the association between cohabitation with parents and stress. Greater stress was related to cohabiting with parents and working for married women.

Eating-out among Korean people has become an important part of modern lifestyle due to tremendous growth of the food service industry and various social and economic changes. This study examined trends in meal patterns and meal sources while eating-out among Korean adults aged 19 years and older. Data were from the 1998-2012 KNHNES (Korea National Health and Nutrition Examination Survey) by the 24-hour dietary recall method. This study included 55,718 adults aged 19 years and older. For analysis of eating-out frequency, data were categorized by source of meals and serving place. Average frequency of meals consumed away from home increased from 1998 to 2012, although it remained lower than that of meals at home. In addition, male, unmarried, employed, higher educated, and high income individuals more frequently consumed meals away from home. Moreover, sodium intake while eating-out significantly increased from 2,370 mg in 1998 to 2,935 mg in 2012. Lastly, percentage contributions of daily total protein intake, fat intake, and sodium intake from eating-out increased to more than half (53-55%) in 2012 compared with 47-48% in 1998. As eating-out has grown in popularity, greater recognition of public health and nutritional education aimed at promoting healthy food choices is needed. In addition to developing consumer education for overall healthier eating patterns, individuals who are younger, unmarried, higher educated, and males are especially at risk and require attention.

Full Text Available Objective The purpose of this community-based study was to determine factors associated with hepatitis B virus (HBV screening compliance and non-compliance among Chinese, Korean, Vietnamese and Cambodian adults with varying levels of English language proficiency. Methods A cross-sectional design was used consisting of a sample of 1,603 Asian adult men and women. Results Overall, 71.4% of the sample reported having never been screened and 28.6% reported being screened for HBV Demographic, acculturation, and barrier factors were differentially associated with screening rates among the subgroups. Demographic factors associated with never-screened were: lower education, younger age, being male, and no insurance for Chinese; lower education, lower income and no insurance for Cambodians; younger age and unmarried for Koreans; and no health insurance for Vietnamese; Acculturation factors associated with never-screened were: not speaking English for Chinese; not speaking English, not reading newspapers in English, and watching TV in one's native language for Cambodians; not speaking English for Koreans; while no significant factors were found for Vietnamese. All barriers were associated with never-screened for Cambodians and Chinese. Those who lacked knowledge about HBV and had language and transportation barrier were more likely to be never-screened for Koreans. There were no significant relationships between the barriers and the screening status for Vietnamese. Conclusions High incidence of HBV and liver cancer in Asian Americans mandates a more vigorous and more culturally and linguistically appropriate educational effort to increase screening and vaccination for HBV in these underserved and mostly uninsured populations.

Full Text Available The hepatitis B virus is second only to tobacco as a known human carcinogen. However, chronic hepatitis B usually does not produce symptoms and people feel healthy even in the early stages of live cancer. Therefore, chronically infected people should perceive it as a serious health problem and move on to appropriate health behaviour. The purpose of this paper is to develop and validate an online program for promoting self-management among Korean patients with chronic hepatitis B. The online program was developed using a prototyping approach and system developing life cycle method, evaluated by users for their satisfaction with the website and experts for the quality of the site. To evaluate the application of the online program, knowledge and self-management compliance of the subjects were measured and compared before and after the application of the online program. There were statistically significant increases in knowledge and self-management compliance in the user group. An online program with high accessibility and applicability including information, motivation, and behavior skill factors can promote self-management of the patient with chronic hepatitis B. Findings from this study allow Korean patients with chronic hepatitis B to engage in proactive and effective health management in the community or clinical practice.

Cytokines/chemokines play key roles in modulating disease progression in human immunodeficiency virus (HIV) infection. Although it is known that early HIV-1 infection is associated with increased production of proinflammatory cytokines, the relationship between cytokine levels and HIV-1 pathogenesis is not clear. The concentrations of 18 cytokines/chemokines in 30 HIV-1 negative and 208 HIV-1 positive plasma samples from Korean patients were measured by the Luminex system. Early HIV-1 infection was classified according to the Fiebig stage (FS) based on the characteristics of the patients infected with HIV-1. Concentrations of interleukin-12 (IL-12), interferon-inducible protein-10 (IP-10), macrophage inflammatory protein-1α (MIP-1α) and regulated upon activation, normal T cells expressed and secreted (RANTES) were increased significantly during the early stage of HIV-1 infection (FS II-IV) compared with the HIV-1-negative group. Of these cytokines, an elevated level of IP-10 was the only factor to be correlated positively with a higher viral load during the early stages of HIV-1 infection (FS II-IV) in Koreans (R = 0.52, P IP-10 may be an indicator for HIV-1 viremia and associated closely with viral replication in patients with early HIV-1 infection. © 2015 Wiley Periodicals, Inc.

Major Obstacles to Implement a Full-Time Intensivist in Korean Adult ICUs: a Questionnaire Survey

Jun Wan Lee

2016-05-01

Full Text Available Background: Critical care physician staffing is a crucial element of the intensive care unit (ICU organization, and is associated with better outcomes in ICUs. Adult ICUs in Korea have been suffering from inadequate full-time intensivists and nurses because of insufficient reimbursement rates (<50% of the original critical care cost from the National Health Insurance System. Recently, full-time intensivists have been introduced as a prerequisite for adult ICUs of tertiary hospitals in Korea. The purpose of this study was to examine the perception of intensivist staffing among critical care program directors regarding the barriers and solutions when implementing an intensivist model of critical care in Korea. Methods: An email survey of critical care program directors in designated teaching hospitals for critical care subspecialty training by the Korean Society of Critical Care Medicine was performed. The survey domains included vision, culture, resources, barriers, and potential solutions to implementing intensivist physician staffing (IPS. Results: Forty-two critical care program directors were surveyed. A total of 28 directors (66.7% responded to email queries. Of these, 27 directors (96.4% agreed that IPS would improve the quality of care in the ICU, although half of them reported a negative perception of relevant clinical colleagues for the role of full-time intensivists and poor resources for IPS in their hospitals. Increased financial burden due to hiring full-time intensivists and concerns regarding exclusion from the management of their critically ill patients in the ICU, together with loss of income for primary attending physicians were stated by the respondents to be major barriers to implementing IPS. Financial incentives for the required cost from the health insurance system and enhancement of medical law relevant to critical care were regarded as solutions to these issues. Conclusions: Critical care program directors believe that

North Korean refugees in South Korea are at high risk of depression, but there are few studies exploring protective factors in this population. We hypothesized that family functioning (family adaptability and cohesion) and resilience would protect North Korean refugees from developing depressive symptoms. A subsample of 304 adult North Korean refugees drawn from the cross-sectional 2010 Nationwide Survey of Domestic Violence in South Korea was analyzed. Approximately 44% of respondents were identified as having depression, using scores on the Center for Epidemiological Studies Depression scale. In models capturing the full spectrum of depressive symptoms (continuous), family cohesion was significantly associated with depression, and the relationship was partially mediated by resilience. In models predicting clinical depression (dichotomous), resilience fully mediated the relationship between family cohesion and clinical depression. In contrast, family adaptability was not associated with depression or resilience in this sample. These findings suggest that assessing and enhancing family cohesion and resilience may be essential for professionals working with refugees, and that refugees without family support may be at particularly high risk for depression.

Full Text Available BackgroundWe investigated the prevalence, awareness, treatment, and control rate of hypertension in Korean adults with diabetes using nationally representative data.MethodsUsing data of 5,105 adults from the fifth Korea National Health and Nutrition Examination Survey in 2011 (4,389 nondiabetes mellitus [non-DM], 242 newly diagnosed with DM (new-DM, and 474 previously diagnosed with DM (known-DM, we analyzed the prevalence of hypertension (mean systolic blood pressure ≥140 mm Hg, diastolic blood pressure ≥90 mm Hg, or use of antihypertensive medication and control rate of hypertension (blood pressure [BP] <130/80 mm Hg.ResultsThe prevalence of hypertension in diabetic adults was 54.6% (44.4% in new-DM and 62.6% in known-DM, P<0.0001 and P<0.0001, respectively compared with non-DM adults (26.2%. Compared to non-DM, awareness (85.7%, P<0.001 and treatment (97.0%, P=0.020 rates were higher in known-DM, whereas no differences were found between new-DM and non-DM. Control rate among all hypertensive subjects was lower in new-DM (14.9%, compared to non-DM (35.1%, P<0.001 and known-DM (33.3%, P=0.004. Control rate among treated subjects was also lower in new-DM (25.2%, compared to non-DM (68.4%, P<0.0001 and known-DM (39.9%, P<0.0001.ConclusionHigher prevalence and low control rate of hypertension in adults with diabetes suggest that stringent efforts are needed to control BP in patients with diabetes, particularly in newly diagnosed diabetic patients.

Full Text Available We investigated the association between socioeconomic status (SES and the prevalence of blepharoptosis in a representative South Korean population.This cross-sectional study was based on data obtained in the Korea National Health and Nutrition Examination Survey from 2010 to 2012. In total, 17,178 Korean adults (7,261 men and 9,917 women aged 19 years or older were enrolled. Blepharoptosis was defined as a marginal reflex distance 1 (MDR 1 lower than 2 mm. Household income and education level were used as indicators of SES. Univariate and multiple logistic regression analyses were conducted to analyze the relationship between SES and the prevalence of blepharoptosis.Household income was inversely associated with the prevalence of blepharoptosis in women [adjusted odds ratio (aOR and corresponding 95% confidence interval (95% CI was 1.894 (1.336, 2.685], and educational level was inversely associated with blepharoptosis in both men and women [aORs and 95% CIs were 1.572 (1.113, 2.219 and 1.973 (1.153, 3.376, respectively]. After adjusting for household income and educational level, low SES was associated with a high prevalence of blepharoptosis in women only.Socioeconomic disparities in the prevalence of blepharoptosis were found among women. Indeed, future research using a prospective design to determine the causal relationship between SES and blepharoptosis may identify SES as a risk factor for this condition.

Full Text Available BackgroundAlthough many anti-diabetic drugs have been used to control hyperglycemia for decades, the efficacy of commonly-used oral glucose-lowering agents in Korean type 2 diabetic patients has yet to be clearly demonstrated.MethodsWe evaluated the efficacy of glimepiride, metformin, and rosiglitazone as initial treatment for drug-naïve type 2 diabetes mellitus patients in a 48-week, double-blind, randomized controlled study that included 349 Korean patients. Our primary goal was to determine the change in HbA1c levels from baseline to end point. Our secondary goal was to evaluate changes in fasting plasma glucose (FPG levels, body weight, frequency of adverse events, and the proportion of participants achieving target HbA1c levels.ResultsHbA1c levels decreased from 7.8% to 6.9% in the glimepiride group (P<0.001, from 7.9% to 7.0% in the metformin group (P<0.001, and from 7.8% to 7.0% (P<0.001 in the rosiglitazone group. Glimepiride and rosiglitazone significantly increased body weight and metformin reduced body weight during the study period. Symptomatic hypoglycemia was more frequent in the glimepiride group and diarrhea was more frequent in the metformin group.ConclusionThe efficacy of glimepiride, metformin, and rosiglitazone as antidiabetic monotherapies in drug-naïve Korean type 2 diabetic patients was similar in the three groups, with no statistical difference. This study is the first randomized controlled trial to evaluate the efficacy of commonly-used oral hypoglycemic agents in Korean type 2 diabetic patients. An additional subgroup analysis is recommended to obtain more detailed information.

Full Text Available Background/Aims : Tens of trillions of microorganisms constitute the gut microbiota of the human body. The microbiota plays a critical role in maintaining host immunity and metabolism. Analyses of the gut microbial composition in Korea are limited to a few studies consisting of small sample sizes. To investigate the gut microbial community in a large sample of healthy Koreans, we analyzed the 16S ribosomal RNA of 4 representative bacterial genera Lactobacillus, Bifidobacterium, Bacteroides, and Clostridium. Methods : A total of 378 DNA samples extracted from 164 infants and 214 adults were analyzed using quantitative real-time polymerase chain reaction. Results : Analysis of 16S ribosomal RNA of 4 representative bacterial genera Lactobacillus, Bifidobacterium, Bacteroides, and Clostridium showed that the gut microbiota in infants had higher relative abundances of Bifidobacterium and Lactobacillus than that in adults, which was dominated by Bacteroides and Clostridium. Conclusions : To the best of our knowledge, this was the first study evaluating the distinct characteristics of the microbial community of Korean infants and adults. The differences between the 2 populations suggest that external factors such as age, diet, and the environment are important contributing factors to the change in gut microbial composition during development.

Ji-Sook Kong

Full Text Available This study was conducted to develop an equation for estimation of 24-h urinary-sodium excretion that can serve as an alternative to 24-h dietary recall and 24-h urine collection for normotensive Korean adults. In total, data on 640 healthy Korean adults aged 19 to 69 years from 4 regions of the country were collected as a training set. In order to externally validate the equation developed from that training set, 200 subjects were recruited independently as a validation set. Due to heterogeneity by gender, we constructed a gender-specific equation for estimation of 24-h urinary-sodium excretion by using a multivariable linear regression model and assessed the performance of the developed equation in validation set. The best model consisted of age, body weight, dietary behavior ('eating salty food', 'Kimchi consumption', 'Korean soup or stew consumption', 'soy sauce or red pepper paste consumption', and smoking status in men, and age, body weight, dietary behavior ('salt preference', 'eating salty food', 'checking sodium content for processed foods', 'nut consumption', and smoking status in women, respectively. When this model was tested in the external validation set, the mean bias between the measured and estimated 24-h urinary-sodium excretion from Bland-Altman plots was -1.92 (95% CI: -113, 110 mmol/d for men and -1.51 (95% CI: -90.6, 87.6 mmol/d for women. The cut-points of sodium intake calculated based on the equations were ≥4,000 mg/d for men and ≥3,500 mg/d for women, with 89.8 and 76.6% sensitivity and 29.3 and 64.2% specificity, respectively. In this study, a habitual 24-hour urinary-sodium-excretion-estimation model of normotensive Korean adults based on anthropometric and lifestyle factors was developed and showed feasibility for an asymptomatic population.

Full Text Available Waldenström macroglobulinemia (WM is a malignant lymphoplasma-proliferative disorder with IgM monoclonal gammopathy. A recent whole-genome study identified MYD88 L265P as the key mutation in WM. We investigated MYD88 mutations in conjunction with cytogenetic study in 22 consecutive Korean WM patients. Conventional G-banding and interphase fluorescence in situ hybridization (FISH were performed at regions including 6q21 using bone marrow (BM aspirates. Sixteen patients were subjected to Sanger sequencing-based MYD88 mutation study. Five patients (28% showed cytogenetic aberrations in G-banding. The incidence of 6q21 deletion was 17% by conventional G-banding and 37% by FISH. Ten patients (45% showed cytogenetic aberrations using FISH: 6q deletion in eight (37% and IGH rearrangement in four (18%. Two patients had both the 6q deletion and IGH rearrangement, and two had only the IGH rearrangement. Eleven patients (69% presented with the MYD88 L265P mutation. MYD88 mutations were significantly associated with the presence of 6q deletions (P=0.037. Six patients with the 6q deletion for whom sequencing was possible were found to harbor MYD88 mutations. The MYD88 L265P mutation was also associated with increased lymphocyte burden in BM biopsy. This is the first report of high frequency MYD88 L265P mutations in Korean WM patients.

This study aimed to assess trends of underweight, obesity, and abdominal obesity and related lifestyle factors in young Korean adults. The analysis focused on adults aged 19-39 years using data from the Korea National Health and Nutrition Examination Survey (KNHANES) I-V (1998-2012). Underweight was defined as body mass index (BMI) obesity as BMI≥30kg/m 2 ; and abdominal obesity as waist circumference ≥90cm in men and ≥85cm in women. We evaluated trends by analyzing the prevalence and odds ratios (ORs) of underweight, obesity, abdominal obesity, and the proportions and ORs of lifestyles. As compared with KNHANES I, the ORs for obesity were higher in III, IV, and V and the ORs for abdominal obesity were higher in IV and V in men, which showed an increasing trend (P for trendobesity showed a significant increasing tendency (P for trendobesity in young men and women, and abdominal obesity in young men is needed. Meanwhile, management of underweight in young women is simultaneously required. Copyright © 2017. Published by Elsevier Ltd.

There has been limited empirical support for interventions designed to promote physical activity targeting mobility in racially diverse older adults. This study aims to examine the effects of a Motivational Physical Activity Intervention (MPAI) on social resource, behavioral change process, physical activity, and mobility variables in sedentary older Korean Americans. A quasi-experimental, repeated-measure, pre- and post-tests design was used. Sixty-four community-dwelling, sedentary older Korean Americans (n = 33 for MPAI group, n = 31 for Attention Control group) participated in the study. There were significant improvements in social resources, including social support from family and friends; behavioral change process variables, including self-efficacy; motivational appraisal; and self-regulation for physical activity. There were significant intervention effects on physical activity, walking endurance, and flexibility. The MPAI is supported as improving mobility and physical activity, as well as increasing motivation for physical activity in older Korean Americans. © The Author(s) 2013.

Pain is often associated with a more rapid progression of cognitive and functional decline, and behavioral disturbance in dementia. Therefore, it is essential to accurately assesses pain for proper intervention in patients with dementia. The Face, Legs, Activity, Cry, and Consolability (FLACC) scale is an excellent behaviour scale which includes most of the domains that are recommended by the American Geriatrics Society to evaluate when assessing pain in patients with dementia. The purpose of this study was to develop the Korean version of the FLACC (K-FLACC) and to verify its reliability and validity in assessing pain of elderly patients with dementia. We developed the K-FLACC to consist of the five domains (face, legs, activity, cry, and consolability) with scores of 0, 1, and 2 for each domain and a total score ranging from 0 to 10 as in the original FLACC. Eighty-eight patients with dementia who visited Konkuk University Medical Center were evaluated. The K-FLACC revealed good validity as compared to the Numeric Rating Scale (NRS; r = 0.617, P dementia in Korea. © 2017 The Korean Academy of Medical Sciences.

The modern education institutes play an important role in fostering professional talents, reproducing knowledge and studies, and forming the identities of certain academic fields and vocational communities. It is a matter of common knowledge that the absence of an official Korean medicine medical school during the Japanese colonial era was a severely disadvantageous factor in the aspects of academic progress, fostering follow-up personnel, and establishment of social capability. Therefore, the then Korean medicine circle put emphasis on inadequate official education institutes as the main factor behind oppression. Furthermore, as the measure to promote the continuance of Korean medicine, the circle regarded establishing civilian Korean medicine training schools as their long-cherished wish and strived to accomplish the mission even after liberation. This study looked into how the Korean medicine circle during the Japanese colonial era utilized civilian training schools to conduct the Korean medicine education conforming to modern medical school and examined how the operation of these training schools influenced the changes in the traditional Korean medicine. After the introduction of the Western medical science, the Korean medicine circle aimed to improve the quality of Korean medicine doctors by establishing modern Korean medicine medical schools. However, after the annexation of Korea and Japan, official Korean medicine medical schools were not established since policies were organized centered on the Western medical science. In this light, the Korean medicine circle strived to nurture the younger generation of Korean medicine by establishing and operating the civilian Korean medicine training schools after the annexation between Korea and Japan. The schools were limited in terms of scale and status but possessed the forms conforming to the modern medical schools in terms of education system. In other words, the civilian training schools not only adhered to the

Post-traumatic stress disorder is common among North Korean refugees who have fled their country for economic, financial and humanitarian reasons. Co-morbid depression and anxiety are also common among North Korean refugees, due to the difficulties they have faced within their country and during their escape journey. Depression and anxiety complicate treatment for post-traumatic stress disorder, and lead to poorer outcomes. Thus, the aim of the present study was to provide a meta-analysis of studies investigating post-traumatic stress disorder, depression, and anxiety among North Korean refugees. Selected articles were published in English, and included measures of post-traumatic stress, and/or depression and anxiety. 10 studies were included in the depression meta-analysis, and 6 in the anxiety meta-analysis. A random-effects model revealed strong, significant associations between post-traumatic stress and depression, r=0.63, 95% CI (0.51, 0.72), pstress, depression and anxiety were higher among adults and those with more than five years outside of North Korea. Depression appears to be an important treatment focus for North Korean refugees with post-traumatic stress.

Many patients with chronic spontaneous/idiopathic urticaria (CSU/CIU) do not respond adequately to treatment with non-sedating H1 antihistamines (H1AH). There are limited studies on use of omalizumab as add-on therapy for treatment of CSU in an Asian population. The POLARIS study (NCT02329223), representing the first randomized, double-blind, placebo-controlled phase III trial of omalizumab for CSU in an Eastern Asian population, evaluated efficacy and safety of omalizumab as add-on therapy for treatment of CSU. This 26-week multicenter (41 Japanese/Korean sites) study enrolled patients (12-75 years) who were symptomatic despite H1AH treatment. Eligible participants (N=218) were randomized 1:1:1 to receive three subcutaneous injections of omalizumab 300mg, 150mg, or placebo every 4 weeks, followed by 12 weeks of follow-up. Primary outcome was change from baseline to Week 12 (Wk12) in weekly itch severity score (ISS7). Safety was assessed through the summary of adverse events (AEs). Baseline demographics and disease characteristics were generally well balanced across treatment groups. At Wk12, statistically significant decreases from baseline were observed in ISS7 with omalizumab vs placebo (mean changes -10.22, -8.80, and -6.51 for omalizumab 300mg, 150mg and placebo; pomalizumab 300mg, 150mg, and placebo groups, respectively); nasopharyngitis was the most frequently reported AE in all treatment arms. The POLARIS study demonstrates that omalizumab is an efficacious and well-tolerated add-on therapy in Japanese and Korean H1AH-refractory patients with CSU. Copyright © 2017 The Authors.

Full Text Available Objective Autonomic symptoms are commonly observed in patients with Parkinson’s disease (PD and often limit the activities of daily living. The Scale for Outcomes in Parkinson’s disease-Autonomic (SCOPA-AUT was developed to evaluate and quantify autonomic symptoms in PD. The goal of this study was to translate the original SCOPA-AUT, which was written in English, into Korean and to evaluate its reliability and validity for Korean PD patients. Methods For the translation, the following processes were performed: forward translation, backward translation, expert review, pretest of the pre-final version and development of the final Korean version of SCOPA-AUT (K-SCOPA-AUT. In total, 127 patients with PD from 31 movement disorder clinics of university-affiliated hospitals in Korea were enrolled in this study. All patients were assessed using the K-SCOPA-AUT and other motor, non-motor, and quality of life scores. Test-retest reliability for the K-SCOPA-AUT was assessed over a time interval of 10−14 days. Results The internal consistency and reliability of the K-SCOPA-AUT was 0.727 as measured by the mean Cronbach’s α-coefficient. The test-retest correlation reliability was 0.859 by the Guttman split-half coefficient. The total K-SCOPA-AUT score showed a positive correlation with other non-motor symptoms [the Korean version of non-motor symptom scale (K-NMSS], activities of daily living (Unified Parkinson’s Disease Rating Scale part II and quality of life [the Korean version of Parkinson’s Disease Quality of Life 39 (K-PDQ39]. Conclusion The K-SCOPA-AUT had good reliability and validity for the assessment of autonomic dysfunction in Korean PD patients. Autonomic symptom severities were associated with many other motor and non-motor impairments and influenced quality of life.

Intracranial arterial stenosis (ICAS) is a common cause of ischemic stroke in Asians. Decreased muscle mass is one of the major causes of chronic disease in adults. The purpose of this study was to analyze the relationship between muscle mass and ICAS in Korean adults. For this study, we selected a total of 10,530 participants (mean age, 43.3 years; 8558 men) in a health screening program, for whom transcranial Doppler (TCD) ultrasound was used to detect >50% ICAS based on criteria modified from the stroke outcomes and neuroimaging of intracranial atherosclerosis trial. Body composition was evaluated by bioelectrical impedance analysis (BIA). Skeletal muscle index (SMI) was calculated with muscle mass/weight (kg) * 100. Among the total patient population, 322 (3.1%) subjects had ICAS. Subjects with ICAS were older, and had higher mean values for fasting glucose, body mass index and blood pressure compared with those without ICAS. Subjects with ICAS had significantly lower muscle mass, SMI and higher percent body fat compared with those without ICAS. In logistic regression analysis, the subjects in the highest tertile of muscle mass had the lowest odds ratio for ICAS with the lowest tertile group of muscle mass as the reference group even after adjusting for age, systolic blood pressure, fasting blood glucose, sex, smoking and exercise (OR 0.650, 95% CI 0.442-0.955). Subjects with ICAS had significantly decreased muscle mass compared with those without ICAS in Korean adults. The risk for ICAS was lower in subjects with higher muscle mass.

Full Text Available With increase of spine surgeries, failed back surgery syndrome (FBSS prevalence is also rising. While complementary and alternative medicine (CAM is commonly used for low back pain (LBP, there are no studies reporting use of integrative Korean medicine in FBSS patients.Patients with pain continuing after back surgery or recurring within 1 year and visual analogue scale (VAS of LBP or leg pain of ≥6 (total n = 120 were recruited at 2 hospital sites from November 2011 to September 2014. Weekly sessions of integrative Korean medicine treatment were conducted for 16 weeks (herbal medicine, acupuncture/electroacupuncture, pharmacopuncture/bee venom pharmacopuncture, and Chuna manual therapy with additional follow-ups at 24 weeks and 1 year. Outcome measures included VAS of LBP and leg pain (primary outcome, Oswestry Disability Index (ODI, Short-Form 36 (SF-36, medical use, and patient global impression of change (PGIC.VAS of LBP and leg pain improved at 6 months (LBP from 6.1±2.0 at baseline to 2.9±2.3; and leg pain from 5.4±2.6 to 2.4±2.5, respectively. Eighty patients (66.7% showed improvement of 50% or more in main pain of LBP or leg pain from baseline. Disability and quality of life also improved at 6 months (ODI from 41.3±12.3 at baseline to 23.6±13.6; and SF-36 from 42.8±14.5 to 62.7±16.8. At 1 year follow-up, conventional medical management use decreased, improvement in pain and disability was maintained, and 79.2% reported improvement of PGIC.Despite limitations as an observational study, integrative Korean medicine treatment showed positive results in pain, function, and quality of life of FBSS patients.

The purpose of this study was to explore health-related quality of life (HRQOL) among Korean patients with osteoporosis and to measure the impact of fractures and comorbidity on their quality of life (QOL) using the Korean National Health and Nutrition Examination Survey (KNHANES) data with a nationwide representativeness. This study was based on 4-year-data obtained from the KNHANES 2008 to 2011. Osteoporosis was diagnosed in 2,078 survey participants according to their bone mineral density measurements using dual energy X-ray absorptiometry. According to the World Health Organization study group, T-scores at or above -1.0 are considered normal, those between -1.0 and -2.5 as osteopenia, and those at or below -2.5 as osteoporosis The EuroQol five-dimensional questionnaire (EQ-5D) index score was used to assess the QOL. Of 2,078 patients diagnosed with osteoporosis, fractures were found to occur at 11.02%. Wrist fracture was the most frequent, affecting 4.52% of the patients, with a significantly different prevalence among men and women ( P <0.001). The overall EQ-5D index score was 0.84±0.01 among patients with osteoporosis. With the exception of cancer, the EQ-5D index score were significantly lower for those having osteoarthritis, rheumatoid arthritis, hypertension, diabetes, chronic obstructive pulmonary disease and cardiovascular events compared to those without the related diseases. We found that low health utility was associated with previous spine fracture and comorbidities in patients with osteoporosis. In particular, the number of fracture experiences greatly deteriorated the HRQOL in patients with osteoporosis. Thus, prevention of secondary fractures and chronic care model for comorbidities should be a priority for osteoporosis management in order to improve HRQOL.

Relaxation technique is an independent nursing intervention used in various stressful situations. The concept of relaxation must be explored for the meaning given by the people in their traditional thought and philosophy. Korean relaxation technique, wanting to become culturally acceptable and effective, is learning to recognize and develop Korean concepts, experiences, and musics of relaxation. This study was aimed at discovering Korean concepts, experiences and musics of relaxation and contributing the development of the relaxation technique for Korean people. The subjects were 59 nursing students, 39 hospitalized patients, 61 housewives, 21 rural residents and 16 researchers. Data were collected from September 4th to October 24th, 1991 by interviews or questionnaires. The data analysis was done by qualitative research method, and validity assured by conformation of the concept and category by 2 nursing scientists who had written a Master's thesis on the relaxation technique. The results of the study were summarized as follows; 1. The meaning of the relaxation concept; From 298 statements, 107 concepts were extracted and then 5 categories "Physical domain", "Psychological domain", "Complex domain", "Situation", and "environment" were organized. 'Don't have discomforts, 'don't have muscle tension', 'don't have energy (him in Korean)', 'don't have activities' subcategories were included in "Physical domain". 'Don't have anxiety', 'feel good', 'emotional stability', 'don't have wordly thoughts', 'feel one's brain muddled', 'loss of desire' subcategories were included in "physical domain" 'Comfort body and mind', 'don't have tension of body and mind', 'be sagged' 'liveliness of thoughts' subcategories were included in "Complex domain". 'Rest', 'sleep', 'others' subcategories were included in "Situation domain". And 'quite environment' & 'comfortable environment' subcategories were included in "Environmental domain". 2.

Full Text Available We aimed to investigate the association between dairy product consumption and the risk of obesity and metabolic syndrome (MetS in Korean adults. Data from 13,692 Korean adults aged ≥19 years from the KNHANES 2010–2013 were used. The study participants were divided into three groups according to the serving size of dairy products they consumed based on a single 24-h recall. About 58% of the Korean adults did not consume any dairy products in one day. In both the sexes, only those who adhered to the recommendation for dairy products (≥1 serving/day achieved the daily requirement of calcium. Women who consumed ≥1 serving/day of dairy products had lower risks of obesity (body mass index ≥ 25 kg/m2 (adjusted odds ratio (AOR, 0.77; 95% confidence interval (CI, 0.66–0.89; p for trend < 0.01 and MetS (AOR, 0.67; 95% CI, 0.56–0.80; p for trend < 0.01 than women who did not consume dairy products. However, these significant associations were not observed in men. In conclusion, consuming ≥ 1 serving/day of dairy products could be an easy and efficient strategy for meeting daily calcium requirement as well as lowering risks of obesity and MetS among Korean women.

Intransigent Vowel-Consonant Position in Korean Dysgraphia: Evidence of Spatial-Constructive Representation

2007-01-01

Full Text Available Dysgraphia due to a focal brain lesion can be characterized by substitution, transposition, deletion and/or addition errors of graphemes or strokes. However, those linguistic errors can be language-specific because the writing system of a given language may influence error patterns. We investigated a Korean stroke patient, a 57-year-old English teacher with dysgraphia both in Korean Han-geul (한글 and in English alphabet writings. The results of an experimental testing revealed transposition errors between a consonant and a vowel only in English but not in Korean writings. This austerity of vowel-consonant position may be attributed to a unique Korean writing system of a spatially well-formed syllabic configuration or block with consonant(s and a vowel. In light of a neuropsychological model of writing, which depicts a multi-level spelling and writing process, we suggest a spatial-constructional component of internal orthographic representations in Korean writing. This Korean graphemic configuration feature may be resistant to a focal, left cerebral damage, and thus, we also discuss our results in terms of cerebral lateralization of the writing processes.

Full Text Available Objective. The aim of this study is to evaluate the consistency of pattern identification (PI, a set of diagnostic indicators used by traditional Korean medicine (TKM clinicians. Methods. A total of 168 stroke patients who were admitted into oriental medical university hospitals from June 2012 through January 2013 were included in the study. Using the PI indicators, each patient was independently diagnosed by two experts from the same department. Interobserver consistency was assessed by simple percentage agreement as well as by kappa and AC1 statistics. Results. Interobserver agreement on the PI indicators (for all patients was generally high: pulse diagnosis signs (AC1=0.66–0.89; inspection signs (AC1=0.66–0.95; listening/smelling signs (AC1=0.67–0.88; and inquiry signs (AC1=0.62–0.94. Conclusion. In four examinations, there was moderate agreement between the clinicians on the PI indicators. To improve clinician consistency (e.g., in the diagnostic criteria used, it is necessary to analyze the reasons for inconsistency and to improve clinician training.

Full Text Available Advances in transportation and communication have broken down critical barriers within the global economy, pushing us towards a more unified world. In keeping with this trend, processes of communication, transportation, and production are becoming increasingly standardized, mechanized, and automated. Yet as this global era of uniformity progresses, people and individuals will inevitably encounter identity confusion. Numerous individuals, ethnicities, nationalities, and countries around the world are working to counteract such identity confusion. As globalization progresses, groups and nationalities that fail to preserve their identities will dwindle and become absorbed by stronger entities. Therefore, many societies are investing great efforts into rediscovering and revamping their indigenous traditions, cultures, and customs. When travelers visit another country, one of the simplest avenues for them to experience the local culture is food. Unlike other cultural elements, many of which have become diluted because of globalization, native cuisines are still perceived as retaining the traditions, uniqueness, and diversity of individual cultures. It is more important than ever for people and countries to expand and preserve their respective cultural currencies. In this respect, taking a cultural approach to Korean cuisine is a fascinating and meaningful endeavor. In light of the recent publication of a few articles dealing with the symbolic significance and meaning behind Korean cuisine, an effort to compile a list of the distinctive cultural properties of Korean food seems vital. Furthermore, presenting the aesthetics of Korean food through a method that integrates science and culture is a very significant task. The authors of this paper firmly believe in its potential to advance the globalization of Korean food.

An increasing number of foreign-born nurses are working in the United States. Nurses' job satisfaction is a critical issue for quality patient care. The purpose of this study was to examine factors affecting the job satisfaction of immigrant Korean nurses. We used a cross-sectional mailed survey design. A convenience sample (n = 105) of members of the Greater New York Korean Nurses Association currently working or had previously worked in the United States completed the questionnaires. We used hierarchical regression to test the effects of acculturation and life satisfaction on job satisfaction. Most participants were female (n = 98, 93.3%) aged 27 to 70 years (mean = 52.27 years, SD = 10.67). In the regression model, life satisfaction, self-esteem, and perceived stress predicted job satisfaction (F = 5.127, p job satisfaction. U.S. nurses need to gain insight into factors influencing job satisfaction in Korean nurses to promote retention and quality care. © The Author(s) 2014.

2017-01-01

This study aimed to compare the usage of Western medicine and traditional Korean medicine for treating joint disorders in Korea. Data of claims from all medical institutions with billing statements filed to HIRA from 2011 to 2014 for the four most frequent joint disorders were used for the analysis. Data from a total of 1,100,018 patients who received medical services from 2011 to 2014 were analyzed. Descriptive statistics are presented as type of care and hospital type. All statistical analyses were performed using IBM SPSS for Windows version 21. Of the 1,100,018 patients with joint disorders, 456,642 (41.5%) were males and 643,376 (58.5%) were females. Per diem costs of hospitalization in Western medicine clinics and traditional Korean medicine clinics were approximately 160,000 KRW and 50,000 KRW, respectively. Among costs associated with Western medicine, physiotherapy cost had the largest proportion (28.78%). Among costs associated with traditional Korean medicine, procedural costs and treatment accounted for more than 70%, followed by doctors' fees (21.54%). There were distinct differences in patterns of medical care use and cost of joint disorders at the national level in Korea. This study is expected to contribute to management decisions for musculoskeletal disease involving joint disorders. PMID:29456569

Despite efforts to interrogate human genome variation through large-scale databases, systematic preference toward populations of Caucasian descendants has resulted in unintended reduction of power in studying non-Caucasians. Here we report a compilation of coding variants from 1,055 healthy Korean individuals (KOVA; Korean Variant Archive). The samples were sequenced to a mean depth of 75x, yielding 101 singleton variants per individual. Population genetics analysis demonstrates that the Korean population is a distinct ethnic group comparable to other discrete ethnic groups in Africa and Europe, providing a rationale for such independent genomic datasets. Indeed, KOVA conferred 22.8% increased variant filtering power in addition to Exome Aggregation Consortium (ExAC) when used on Korean exomes. Functional assessment of nonsynonymous variant supported the presence of purifying selection in Koreans. Analysis of copy number variants detected 5.2 deletions and 10.3 amplifications per individual with an increased fraction of novel variants among smaller and rarer copy number variable segments. We also report a list of germline variants that are associated with increased tumor susceptibility. This catalog can function as a critical addition to the pre-existing variant databases in pursuing genetic studies of Korean individuals.

The neuronal migration disorders, X-linked lissencephaly syndrome (XLIS) and subcortical band heterotopia (SBH), also called "double cortex", have been linked to missense, nonsense, aberrant splicing, deletion, and insertion mutations in doublecortin (DCX) in families and sporadic cases. Most DCX mutations identified to date are located in two evolutionarily conserved domains. We performed mutation analysis of DCX in two Korean patients with SBH. The SBH patients had mild to moderate developmental delays, drug-resistant generalized seizures, and diffuse thick SBH upon brain MRI. Sequence analysis of the DCX coding region in Patient 1 revealed a c.386 C>T change in exon 3. The sequence variation results in a serine to leucine amino acid change at position 129 (S129L), which has not been found in other family members of Patient 1 or in a large panel of 120 control X-chromosomes. We report here a novel c.386 C>T mutation of DCX that is responsible for SBH. PMID:16100463

Chronic kidney disease (CKD) has often been defined based on glomerular filtration rate (GFR) alone. The Kidney Disease: Improving Global Outcomes guideline highlights albuminuria in the CKD definition. Thus, we investigated the association between obesity and CKD, as defined by both GFR and albuminuria, in Korean adults. We used Korea National Health and Nutrition Examination Survey 2011-2014 data (N = 19,331, ≥19 years old) representing the national Korean population. CKD was classified by (1) estimated GFR (eGFR) obesity and each CKD category were evaluated using multivariate logistic regression analysis. The prevalence rates of CKD GFR , CKD ACR , and CKD Risk were 2.2%, 6.7%, and 8.1%, respectively. Compared with the normal body mass index (BMI; 18.5-22.9 kg/m 2 ) group, men with BMI ≥ 25 kg/m 2 had 1.88 times greater risk of CKD GFR in the adjusted model [95% confidence interval (CI), 1.26-2.80; P = 0.002]; BMI was not significantly associated with CKD GFR in women. In contrast, both men and women with BMI ≥ 25 kg/m 2 had 1.58 and 1.40 times higher risk of CKD ACR (95% CI, 1.21-2.07 and 1.08-1.81, respectively, both P Obese men and women had 1.65 and 1.38 times higher risk of CKD Risk (95% CI, 1.29-2.12 and 1.09-1.75, respectively, both P Obesity was significantly associated with an increased ACR-based CKD risk. Longitudinal studies are needed to investigate the role of overweight and obesity in the development and progression of CKD.

This study was carried out to investigate the relationship between the therapeutic effects of treatment for tic disorder and Korean medicine clinical tests, including body mass index (BMI) and heart variability rate (HRV). This study was not a clinical trial, but a data analysis of 87 tic patients who were treated for 6 months during the time period from Nov. 2010 to Jan. 2012. The clinical evaluation of the symptoms was recorded using the Korean version of the Yale Global Tic Severity Scale (YGTSS). The BMI and the HRV were measured according to a schedule, and various kinds of statistical methods were used. Among the 87 patients, the number of males was 3.34 times the number of females, and 58 patients (66.7%) had been suffering for more than 12 months. The onset age of the males was significantly lower than that of the females, and males had the symptoms longer than females had. Also, males with a family history of tics were 2.5 times as many as females, and their onset ages were substantially lower. At the first medical examinations, the average score on the YGTSS was 34.08, and it decreased linearly as the treatment progressed. After 4 and 6 months of treatment, it had decreased significantly. The YGTSS score and the period of suffering correlated positively. At the first visit, each HRV datum was in the normal range. After the 6 months' treatment, Ln (TP), Ln (LF), and Ln (HF) had dropped substantially in the normal range while Ln (VLF) and the LF/HF ratio had not changed in a meaningful way. During the treatment period, the BMI stayed relatively constant without any meaningful changes. Copyright © 2013. Published by Elsevier B.V.

Among the many causes of rotator cuff tears, scapular morphology is associated with the accelerating degenerative process of the rotator cuff. Acromion index (AI) was previously introduced and compared in two populations. We enrolled 100 Korean patients diagnosed with full-thickness rotator cuff tears by magnetic resonance imaging and intraoperative arthroscopic findings between January and December 2013. Another 100 Korean patients with an intact rotator cuff tendon identified on magnetic resonance imaging and other shoulder diseases, such as frozen shoulder and instability, were enrolled as controls. We retrospectively compared these 100 rotator cuff tear patients (mean age, 63 years) and 100 controls (mean age, 51 years) in this study. Two independent orthopedic surgeons assessed the AI on radiographs. We performed an interobserver reliability test of the AI assessment, and then compared the AI between two groups. The measurement of the AI showed excellent reliability (intraclass correlation coefficient, 0.82). The mean AI in the rotator cuff tear group was 0.68 and it was significantly different between groups ( p rotator cuff tears in a Korean population.

to understand the prenatal genetic testing decision-making processes among pregnant Korean-American women. a qualitative, descriptive research design. referrals and snowball sampling techniques were used to recruit 10 Korean-American women who had been recommended for amniocentesis during pregnancy in the United States (U.S.). All participants were born in Korea and had immigrated to the U.S. The number of years living in the U.S. ranged from 4 to 11 (M=5.7). various regional areas of the U.S. the researchers conducted face-to-face or phone interviews using semi-structured interview guides. The interviews were conducted in the Korean language and lasted approximately 50-100minutes. The interview guides focused on the decision-making process and experiences with prenatal genetic testing, as well as reflections on the decisions. Four core themes emerged related to the participants' decision-making processes, according to their descriptions. These themes are (1) facing the challenges of decision-making, (2) seeking support, (3) determining one's preferred role in the decision-making process, and (4) feeling uncomfortable with the degree of patient autonomy in U.S. health care. researchers concluded that many distinctive factors influence the decision-making processes used by pregnant Korean-American women. The results have the potential to improve shared decision-making practices regarding prenatal genetic testing. clinicians need to understand the sociocultural underpinnings of pregnant Korean-American immigrants regarding prenatal genetic screening and testing as an initial step to engage these patients in shared decision-making.

Little is known about the effects of socio-environmental factors on dental caries in different demographic situations in Asian populations. We investigated whether the nature of the association between regional socio-economic context and dental caries experience differed according to gender and age groups in Korean adults. We obtained a linked data set containing individual information from the 2000 Korean National Oral Health Survey and regional information from the "Major statistical indices of Si-Gun-Gu" (city-county-ward), published by the Korean Statistical Office. We stratified participants into women and men and into four 10-year-interval age groups (19-34, 35-44, 45-54, and 55-64 years) and analysed the linked data using a multilevel analysis. In total, 5,259 individuals were included in the final study population. Regional socio-economic context was significantly associated with dental caries experience in men, but not in women. The patterns of the association between regional contextual variables and dental caries experience differed among age groups. People 35-44 years of age living in areas less dependent on the manufacturing industry and those 45-54 years of age living in areas where local government was relatively poor were more prone to have caries experience. The results of this study indicated that socio-economic factors affecting residents' dental health status may operate through different mechanisms or degrees according to geographic location, suggesting that some gender- and age-defined subgroups may be likely to benefit from different types of intervention, including the development of specific health policies.

Suicide is a major concern for increasing mortality in bipolar patients, but risk factors for suicide in bipolar disorder remain complex, including Korean patients. Medical records of bipolar patients were retrospectively reviewed to detect significant clinical characteristics associated with suicide attempts. A total of 579 medical records were retrospectively reviewed. Bipolar patients were divided into two groups with the presence of a history of suicide attempts. We compared demographic characteristics and clinical features between the two groups using an analysis of covariance and chi-square tests. Finally, logistic regression was performed to evaluate significant risk factors associated with suicide attempts in bipolar disorder. The prevalence of suicide attempt was 13.1% in our patient group. The presence of a depressive first episode was significantly different between attempters and nonattempters. Logistic regression analysis revealed that depressive first episodes and bipolar II disorder were significantly associated with suicide attempts in those patients. Clinicians should consider the polarity of the first mood episode when evaluating suicide risk in bipolar patients. This study has some limitations as a retrospective study and further studies with a prospective design are needed to replicate and evaluate risk factors for suicide in patients with bipolar disorder.

Purpose The aim of this study was to examine patterns of radiotherapy (RT) in Korean patients with hepatocellular carcinoma (HCC) according to the evolving guideline for HCC established by the Korean Liver Cancer Study Group-National Cancer Center (KLCSG-NCC). Materials and Methods We reviewed 765 patients with HCC who were treated with RT between January 2011 and December 2012 in 12 institutions. Results The median follow-up period was 13.3 months (range, 0.2 to 51.7 months). Compared with previous data between 2004 and 2005, the use of RT as a first treatment has increased (9.0% vs. 40.8%). Increased application of intensity-modulated RT resulted in an increase in radiation dose (fractional dose, 1.8 Gy vs. 2.5 Gy; biologically effective dose, 53.1 Gy10 vs. 56.3 Gy10). Median overall survival was 16.2 months, which is longer than that reported in previous data (12 months). In subgroup analysis, treatments were significantly different according to stage (p < 0.001). Stereotactic body RT was used in patients with early HCC, and most patients with advanced stage were treated with three-dimensional conformal RT. Conclusion Based on the evolving KLCSG-NCC practice guideline for HCC, clinical practice patterns of RT have changed. Although RT is still used mainly in advanced HCC, the number of patients with good performance status who were treated with RT as a first treatment has increased. This change in practice patterns could result in improvement in overall survival. PMID:27338036

Full Text Available A recent Korea National Health and Nutrition Survey indicated inadequate riboflavin intake in Koreans, but there is limited research regarding riboflavin status in South Korea. The purpose of this study was to determine riboflavin intake and status of Korean adults. Three consecutive 24-h food recalls were collected from 412 (145 men and 267 women healthy adults, aged 20–64 years, living in South Korea and urine samples were collected from 149 subjects of all subjects. The dietary and total (dietary plus supplemental riboflavin intake was 1.33 ± 0.34 and 2.87 ± 6.29 mg/day, respectively. Approximately 28% of the subjects consumed total riboflavin less than the Estimated Average Requirement. Urinary riboflavin excretion was 205.1 ± 190.1 μg/g creatinine. Total riboflavin intake was significantly positively correlated to the urinary riboflavin excretion. (r = 0.17171, p = 0.0363. About 11% of the Korean adults had urinary riboflavin <27 μg/g creatinine indicating a riboflavin deficiency and 21% had low status of riboflavin (27 μg/g creatinine ≤ urinary riboflavin < 80 μg/g creatinine. Thus, one-third of Korean adults in this study had inadequate riboflavin status. In some adults in Korea, consumption of riboflavin-rich food sources should be encouraged.

Full Text Available BackgroundLatent autoimmune diabetes in adults (LADA refers to a specific type of diabetes characterized by adult onset, presence of islet auto-antibodies, insulin independence at the time of diagnosis, and rapid decline in β-cell function. The prevalence of LADA among patients with type 2 diabetes varies from 2% to 20% according to the study population. Since most studies on the prevalence of LADA performed in Korea were conducted in patients who had been tested for anti-glutamic acid decarboxylase antibody (GADAb, a selection bias could not be excluded. In this study, we examined the prevalence and clinical characteristics of LADA among adult patients recently diagnosed with type 2 diabetes.MethodsWe included 462 patients who were diagnosed with type 2 diabetes within 5 years from the time this study was performed. We measured GADAb, fasting insulin level, fasting C-peptide level, fasting plasma glucose level, HbA1c, and serum lipid profiles and collected data on clinical characteristics.ResultsThe prevalence of LADA was 4.3% (20/462 among adult patients with newly diagnosed type 2 diabetes. Compared with the GADAb-negative patients, the GADAb-positive patients had lower fasting C-peptide levels (1.2±0.8 ng/mL vs. 2.0±1.2 ng/mL, P=0.004. Other metabolic features were not significantly different between the two groups.ConclusionThe prevalence of LADA is 4.3% among Korean adult patients with recently diagnosed type 2 diabetes. The Korean LADA patients exhibited decreased insulin secretory capacity as reflected by lower C-peptide levels.

To evaluate the reliability and validity of the Korean version of the 39-item Parkinson's disease questionnaire (PDQ-39). Cross-cultural adaptation was performed according to the international guidelines: forward and backward translation, focus group meeting, and a field test. With Korean consensus translation produced, validation was assessed by evaluating reliability and validity. Ninety-three outpatients with Parkinson's disease (PD) and 89 healthy aged controls were recruited. Internal consistency reliability was assessed by Cronbach's alpha. Validity was assessed by Spearman correlation analysis, t test, factor analysis, and analysis of variance with Duncan's multiple range tests. In the PD group, mean age was 65.13 ± 9.84 years, and mean duration of PD was 42.41 ± 37.01 months. Ceiling and floor effects ranged 1.1%-2.2% and 1.1%-15.1%, respectively. Cronbach's alpha of eight dimensions ranged from .70 to .97. All dimensions were correlated with each other, except for the stigma dimension. PD patients had significantly lower quality of life than healthy aged controls did, except for the bodily discomfort dimension. Eight dimensions of Korean PDQ-39 loaded on one factor. PD patients with a Modified Hoehn and Yarh Staging score of 4 had the worst quality of life. The relationships among the eight dimensions of Koran PDQ-39 and the Modified Hoehn and Yarh Staging is fair to good, except for the stigma and social support dimension. The Korean PDQ-39 was proved to be reliable and valid. Our results suggest that Korean PDQ-39 could be used in clinical research to assess and evaluate the disease process and its impacts on health-related quality of life in Korean PD patients.

Full Text Available BackgroundThe common characteristics of metabolic syndrome (MetS and Cushing's syndrome suggest that excess cortisol may be involved in the pathogenesis of MetS. Salivary cortisol measurements are simple and can be surrogates for plasma free cortisol, which is the most biologically active form. We evaluated the association between levels of midnight salivary cortisol and MetS in Korean adults.MethodsA total of 46 subjects, aged 20 to 70 years, who visited the Health Care Center at Konkuk University Hospital from August 2008 to August 2009 were enrolled. We compared the levels of midnight salivary cortisol in subjects with MetS with those in subjects without MetS. We analyzed the associations between midnight salivary cortisol levels and components of MetS.ResultsMidnight salivary cortisol levels were higher in the MetS group (70±42.4 ng/dL, n=12 than that in the group without MetS (48.1±36.8 ng/dL, n=34 (P=0.001. Positive correlations were observed between midnight salivary cortisol levels and waist circumference, fasting blood glucose, and homeostasis model assessment of insulin resistance. The risk for MetS was significantly higher in subjects with midnight salivary cortisol levels ≥100 ng/dL than in those with levels <50 ng/dL (odds ratio, 5.9; 95% confidence interval, 2.35 to 36.4.ConclusionThe results showed a positive correlation between midnight salivary cortisol levels and MetS, suggesting that hypercortisolism may be related to MetS.

As the use of beverages in diets is increasing, several studies have examined the effect of beverage consumption in human health. Thus, we aimed at identifying specific beverage patterns and determining their associations with obesity and metabolic syndrome (MetS) risk factors in Korean adults. Based on the Korea National Health and Nutrition Examination Survey (KNHANES) 2008-2012 data, 19,800 Korean adults (≥20 years) with a single 24-h dietary recall and health examination data were investigated. All beverage items consumed by participants were categorized into 15 beverage groups based on the KNHANES coding system. Three major beverage consumption patterns were identified according to factor analysis: (1) the "healthy beverage" (high intake of dairy products, 100% fruit/vegetable juices and low intake of alcoholic beverages); (2) the "sugar-sweetened beverage" (high intake of soda, sweetened coffee/tea, and fruit drink); and (3) the "unsweetened beverage" (high intake of unsweetened coffee) patterns. Multivariable logistic regression analyses were conducted to determine the odds of obesity (body mass index ≥25 kg/m 2 ) and MetS (defined by National Cholesterol Education Program III [NCEP III]) for each beverage pattern after controlling for covariates. Adjusted odds ratios (AORs) and 95% confidence intervals (CIs) for associations of the "healthy beverage" pattern with risks of obesity, abdominal obesity, and elevated triglycerides, fasting blood glucose (FBG), and blood pressure (BP) were 0.88 (0.79-0.98), 0.83 (0.74-0.92), 0.88 (0.78-0.99), 0.85 (0.79-0.98), and 0.81 (0.72-0.92), respectively. AORs (95% CIs) of associations of the "sugar-sweetened beverage" pattern with risks of abdominal obesity, elevated FBG and BP were 1.15 (1.03-1.30), 1.14 (1.01-1.29), and 1.18 (1.04-1.33), respectively. However, no associations were found between the "unsweetened beverage" pattern and any parameters examined. Intake of healthy beverages should be encouraged to

Background In recent years, some reports have suggested that papillary thyroid cancers are more frequently associated with lymphocytic thyroiditis or Hashimoto's thyroiditis. This study investigated a potential increase in the prevalence of chronic lymphocytic thyroiditis among papillary thyroid cancer patients. Materials and Methods We used national epidemiological survey data on thyroid cancer patients diagnosed in 1999, 2005, and 2008. A retrospective medical record survey was conducted by representative sampling of a national cancer incidence database. The analysis included 5,378 papillary thyroid cancer patients aged 20–79 years. We calculated the age-standardized prevalence and age-adjusted prevalence ratios using a binomial regression model with a log link for the prevalence of chronic lymphocytic thyroiditis among papillary thyroid cancer patients by sex for each year. Results The prevalence of chronic lymphocytic thyroiditis among papillary thyroid cancer patients was 4.0% and 12.8% for men and women in 1999, 6.5% and 24.6% in 2005, and 10.7% and 27.6% in 2008, respectively. Between 1999 and 2008, the age-standardized prevalence of chronic lymphocytic thyroiditis increased 4.1-fold in male patients and 2.0-fold in female patients with papillary thyroid cancer. The prevalence of other thyroid diseases, however, did not increase in either gender. Conclusions Among Korean papillary thyroid cancer patients, the prevalence of chronic lymphocytic thyroiditis increased between 1999 and 2008, whereas the prevalence of other thyroid disorders did not change.

Drawing on the person-environment (P-E) fit perspective, this study examined the role of environment on the well-being of vulnerable older adults in a non-western context. Using the indicators from the World Health Organization's (WHO) framework for age friendly cities (ACF), we examined life satisfaction among South Korean older adults, exploring the extent to which multidimensional environmental characteristics are associated with low socioeconomic status (SES). Using the regionally representative data from the Seoul City-wide needs assessment of middle- and old-aged adults, an analytic sample (N = 1657) focused on community-living individuals aged 65 and older. Multilevel regression models examined interaction between SES subgroups and varying aspects of the environment (i.e. physical, social, and service environment) as related to life satisfaction. Consistent with the environmental docility hypothesis, members of the most vulnerable subgroup in the Korean context - older adults who are living alone and poor - are more likely to have higher life satisfaction when they have higher levels of support in physical and social environments. Interestingly, a higher level of support in the service environment was related to lower life satisfaction for this subgroup. This study provides an empirical foundation for efforts to identify age-friendly environmental characteristics as modifiable environmental resources that can improve older adults' psychological well-being. As the first attempt to use WHO ACF indicators within the P-E fit perspective in a non-Western context, our study provides a foundation for designing support services or programs that effectively meet the needs of vulnerable older adults.

The purpose of this study was to investigate whether the intakes of some kinds of vitamins and minerals are associated with periodontitis in a nationally representative sample of young adults. This study comprised 2049 young adults aged 19-39 years who took both periodontal examination and nutrition survey. The vitamin and mineral intakes were calculated from dietary intake data gained by complete one-day 24-h recall interviews, and the intake levels for each nutrient were classified by the Recommended Nutrient Intake (RNI) in Dietary Reference Intakes for Koreans and median values. Periodontitis was assessed using Community Periodontal Index (CPI). Multivariate logistic regression analyses were performed in a whole sample and subgroups with the strata of gender or smoking, following a complex sampling design. In analyses according to RNI, a lower intake of niacin was significantly associated with periodontitis in young adults (odd ratio [OR] 1.47, 95% confidential interval [CI] 1.09-2.00) and in its subgroup of women (OR 1.70; 95% CI 1.10-2.64) and current non-smokers (OR 1.75; 95% CI 1.22-2.51). Whereas, in analyses according to median intake values, there were significant associations of periodontitis with a lower intake of niacin in women (OR 1.58; 95% CI 1.02-2.46) and current non-smokers (OR 1.50; 95% CI 1.01-2.22), with lower intake of vitamin C in women (OR 1.66; 95% CI 1.04-2.64) and in current non-smokers (OR 1.49; 95% CI 1.04-2.14), with lower intake of iron in women (OR 1.85; 95% CI 1.11-3.07), and with lower intake of vitamin A marginally in women (OR 1.56; 95% CI 1.00-2.44). In young adults, periodonitis is significantly associated with the lower intakes of niacin, vitamin C, and iron, especially in women and current non-smokers.

The question of whether religion has beneficial or detrimental effects on the mental well-being of the adult individual is debatable. Because most Korean citizens are free to select their own religion, there is a higher proportion of non-believers than believers among the Korean population. The aim of this research was to investigate the association between spiritual values and Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition mental disorders in Korea across all types of belief systems, including Koreans not affiliated with a particular religion. The Korean version of the Composite International Diagnostic Interview 2.1 was used to interview 6,275 people across South Korea in 2001. While controlling for age and sex, we used logistic regression to analyze the relationship between mental disorders (both current and past) and the types of religion and spiritual values. Strong spiritual values were positively associated with increased rates of current depressive disorder and decreased rates of current alcohol use disorder. Using "atheist" as the reference category, Catholics had higher lifetime odds of single episodes of depression whilst Protestants had higher lifetime odds of anxiety disorder and lower lifetime odds of alcohol use disorders. The results of this study suggest that depressive episodes often lead to a search for spirituality and that religion may be helpful in overcoming depression or becoming less vulnerable to relapsing. The associations between religion, spiritual values, and mental health have not been fully elucidated and warrant further exploration.

We explored attitudes about prevention, screening and treatment of hepatitis B virus (HBV) infection in Chinese, Korean and Vietnamese communities. We use qualitative methods in 12 focus groups (n = 113) of adults who self-reported their ethnicity to be Chinese, Korean, or Vietnamese. We use grounded theory (i.e., consensus-building between co-coders about recurring, emerging themes) for analysis. Diet, nutrition, fatigue and stress were misidentified as HBV causes. Improving hygiene, diet, exercise, and holistic methods were misidentified as viable HBV prevention methods. Common screening problems included not affording test and not understanding test results. Participants shared reasons for using complementary and alternative medicine--when Western medicine fails or becomes unaffordable. Participants sought information from medical providers and fellow community members, but also from the internet. Many of the attitudes and opinions that emerged may deter participation in HBV screening, prevention and treatment, insofar as community members may factor them into healthcare decision-making, choose alternative but ineffective methods of prevention and treatment, and undervalue the benefits of screening. More patient education in both traditional and new media is necessary for clarifying transmission, screening and treatment misunderstandings.

Background Magnesium is known to lower the risk of cardiovascular disease. However, studies on its relationship with hypertension, a single and common cause of various chronic diseases, are limited and their findings are not consistent. The purpose of the present study is to identify the relationship between magnesium intake and high blood pressure (HBP) risk in Koreans. Methods This research is a cross-sectional study based on the 2007~2009 Korean National Health and Nutritional Examination Survey data. This study investigated 11,685 adults aged over 20 to examine their general characteristics, anthropometry and blood pressure. Daily magnesium intake was analyzed using the 24-hour dietary recall method. To calculate the odds ratio (OR) of HBP risk (130/85 mmHg or over) according to the quartile of magnesium intake (mg/1000kcal) together with its 95% confidence interval (CI), multivariable logistic regression analysis was performed. Results No significant association between dietary magnesium intake and the risk of HBP was found. In obese women, particularly, after adjusting relevant factors, the adjusted odds ratio of HBP prevalence in the highest magnesium intake quartile was 0.40 compared with the lowest magnesium intake quartile (95% CI = 0.25~0.63, P for trend = 0.0014). Women, especially obese women, were found to have a negative relationship of magnesium intake with HBP. Conclusions The present results indicate that sufficient magnesium intake could be useful in decreasing the high blood pressure risk of obese women. PMID:26075385

The radiological measurement of the interpedicular disease using a routine antero-posterior view of the spine gives important clinical criteria in evaluation of the intraspinal tumor and stenosis of the spinal canal, and aids for diagnosis of the lesions. In 1934 Elsberg and Dyke reported values of interpedicular distance as determined on roentgenograms for spine of white adult, and in 1968 Song prepared normal values of interpedicular distance for Korean adult. The present investigation was undertaken to provide normal interpedicular distance of Korean teenagers. The author observed the antero-posterior films of the spine of 200 normal teenagers which were composed of 100 male and 100 female. The normal values of the interpedicular distance of Korean teenagers were obtained, as well as 90% tolerance range for clinical use. In this statistical analysis, there were noted significant differences between male and female, and each age groups. It was observed that average male measurement were consistently larger than female by about 1 mm and the growth of the spinal canal appeared to be continued.

A common ancestral haplotype is strongly suggested in the Korean and Japanese patients with Fanconi anemia (FA), because common mutations have been frequently found: c.2546delC and c.3720_3724delAAACA of FANCA; c.307+1G>C, c.1066C>T, and c.1589_1591delATA of FANCG. Our aim in this study was to investigate the origin of these common mutations of FANCA and FANCG. We genotyped 13 FA patients consisting of five FA-A patients and eight FA-G patients from the Korean FA population. Microsatellite markers used for haplotype analysis included four CA repeat markers which are closely linked with FANCA and eight CA repeat markers which are contiguous with FANCG. As a result, Korean FA-A patients carrying c.2546delC or c.3720_3724delAAACA did not share the same haplotypes. However, three unique haplotypes carrying c.307+1G>C, c.1066C > T, or c.1589_1591delATA, that consisted of eight polymorphic loci covering a flanking region were strongly associated with Korean FA-G, consistent with founder haplotypes reported previously in the Japanese FA-G population. Our finding confirmed the common ancestral haplotypes on the origins of the East Asian FA-G patients, which will improve our understanding of the molecular population genetics of FA-G. To the best of our knowledge, this is the first report on the association between disease-linked mutations and common ancestral haplotypes in the Korean FA population. © 2015 John Wiley & Sons Ltd/University College London.

The purpose of this study is to determine an appropriate age threshold at which to recommend the evaluation of moderate and severe periodontitis among Korean adults.This study involved a cross-sectional analysis using data from the Korean National Health and Nutrition Examination Survey from 2012 to 2014. Incidence rates of periodontitis with the 95% confidence interval (CI) were evaluated. The predictive accuracy of age for periodontitis was determined by calculating the area under curve (AUC) on the basis of the receiver operating characteristic (ROC) curve.The cutoff value of age was 43 years in men having periodontitis with an AUC of 0.70 with 95% CI of 0.69 to 0.72. The AUC was 0.72 (95% CI: 0.70-0.73), and the cutoff value of age (49 years) was identified for the moderate periodontitis in women. The cutoff values for age with AUCs and 95% CI for individuals with periodontitis were 46 years (0.72 [0.71-0.73]), 43 years (0.73 [0.72, 0.74]), 45 years (0.71 [0.70,0.72]), 43 years (0.73 [0.72, 0.74]), and 45 years (0.74 [0.72, 0.75]) for no obesity, no abdominal obesity, no diabetes mellitus, no hypertension, and no metabolic syndrome groups, respectively.This study proposed the guideline for the appropriate age threshold at which to recommend the evaluation of moderate and severe periodontitis for the general population and additionally added the guideline for the individuals without systemic disease including diabetes mellitus, hypertension, metabolic syndrome, and obesity. This study suggests that the participants with certain age may be recommended for the regular periodontal evaluation.

In this study, we examined the relationship between GC polymorphisms and plasma vitamin D3 level in Korean patients with COPD. Methods: The study included 175 COPD patients from the Korean Obstructive Lung Disease Cohort. Multivariate analysis was conducted with adjustment for age, body mass index (BMI, lung function, smoking status, smoking amount, and seasonal variation in blood vitamin D level. Vitamin D deficiency was defined as a plasma 25-hydroxyvitamin D3 level lower than 20 ng/mL. Results: The mean plasma vitamin D3 level was 17.5 ng/mL. The GC1F variant (44.3% and genotype 1F-2 (27.4% were the most common. The plasma vitamin D3 level was lower in patients with the GC2 variant (estimated =-3.73 ng/mL and higher in those with genotype 1F-1S (estimated =4.08 ng/mL. The GC2 variant was a significant risk factor for vitamin D deficiency (odds ratio =2.41. Among COPD clinical parameters, vitamin D deficiency was associated with a lower ratio of forced expiratory volume in 1 second to forced vital capacity (FEV1/FVC regardless of GC polymorphisms. FEV1/FVC was higher in patients with genotype 1F-1F (estimated =3.61% and lower in those with genotype 1F-2 (estimated =-3.31%. The

In view of the clinical importance of angiotensin-converting enzyme (ACE) as a major marker for cardiovascular diseases, we investigated insertion/deletion (I/D) polymorphism of the ACE gene in Koreans. Genotype frequencies were examined by polymerase chain reaction in 171 patients with coronary artery disease (CAD) and 120 healthy subjects. Allele frequencies of ACE polymorphism in Koreans were not significantly different between patient and control groups. In addition, association between ACE genotypes and the number of stenosed coronary arteries was not detected. ACE genotypes in the CAD group were not associated with body mass index and plasma lipid levels. Thus, our results suggest that, at least in Koreans, I/D polymorphism of the gene is unlikely to be a useful marker for CAD subjects. However, the I allele frequency of Koreans (0.58) was higher than that of Caucasian populations (0.47) but lower than that of Samoan (0.91) and Yanomami (0.85) populations. Here, we discuss the clinical and ethnic importance of ACE polymorphism.

To document the radiologic characteristics of Korean Gaucher disease. Fifteen bone marrow biopsy and laboratory data confirmed Gaucher disease patients (age 1-21, mean 10.9 yr) were undertaken plain X ray and MRI. Number of type I were 10, type II, 2, type III, 3. Seven were splencetomized on initial evaluation or during follow up. Five enzyme treated patient were undertaken follow-up MR examination during 6-40 month with 6 month interval. Conventional T1 and T2WI of spine and femur was performed and FMPSPGR in and out of phase image was also done. Volume of liver and spleen were measured, and bone marrow infiltration and presence of infarction were scored according to 6 scale scoring system. Clinical data were also reviewed and correlated with the MR findings. Marrow infiltration was noted in 71.4% of all patients in MRI, while it was in 45.7% with plain radiography. Type I group showed marrow infiltration in all but one cases, which was parallel with ages, SGPT, and presence of osteopenia, reversely correlated with spleen size. Severe bone complications (infarction of fracture) were noted in 7 of 10 type I group, and 6 patients showed severe growth retardation (below 3rd percentile). Follow up MR examination of 5 patient showed decrease in liver and spleen size first without bone change until 6 months. There showed bone regeneration in 2 patient 1 year after, and increased fat signal in one patient 3.5 years after. In and out of phase images couldn't help in quantifying fat composition in bone marrow. Korean Gaucher patients revealed as more severe skeletal complications than others reported from Western groups. MR examination is a effective modality to evaluate and monitor of Gaucher patients

The aim of the present study was to assess normal eyeball protrusion from the orbital rim using two- and three-dimensional images and demonstrate the better suitability of CT images for assessment of exophthalmos. The facial computed tomographic (CT) images of Korean adults were acquired in sagittal and transverse views. The CT images were used in reconstructing three-dimensional volume of faces using computer software. The protrusion distances from orbital rims and the diameters of eyeballs were measured in the two views of the CT image and three-dimensional volume of the face. Relative exophthalmometry was calculated by the difference in protrusion distance between the right and left sides. The eyeball protrusion was 4.9 and 12.5 mm in sagittal and transverse views, respectively. The protrusion distances were 2.9 mm in the three-dimensional volume of face. There were no significant differences between right and left sides in the degree of protrusion, and the difference was within 2 mm in more than 90% of the subjects. The results of the present study will provide reliable criteria for precise diagnosis and postoperative monitoring using CT imaging of diseases such as thyroid-associated ophthalmopathy and orbital tumors.

Full Text Available Diagnostic delay frequently occurs in Crohn's disease (CD patients because of diagnostic limitations. However, diagnostic delay and its related factors remain poorly defined. Therefore, we aimed to identify the predictors associated with diagnostic delay and to evaluate the impact of diagnostic delay on clinical course in a Korean CD patient cohort. We performed a multicenter retrospective analysis of 1,047 CD patients registered in the Crohn's Disease Clinical Network and Cohort study in Korea. The mean interval of diagnostic delay was 16.0 ± 33.1 months. Multivariate analysis showed that older age at diagnosis (≥40 years (p = 0.014, concomitant upper gastrointestinal (UGI disease (p = 0.012 and penetrating disease behavior at diagnosis (p = 0.001 were positively associated with long diagnostic delay (≥18 months. During the longitudinal follow-up, long diagnostic delay was independently predictive of further development of intestinal stenosis (hazard ratio [HR], 1.43; 95% confidence interval [CI], 1.07-1.93; p = 0.017, internal fistulas (HR, 1.62; 95% CI, 1.12-2.33; p = 0.011, and perianal fistulas (HR, 1.38; 95% CI, 1.06-1.80; p = 0.016. However, as for the risk of abscess formation, bowel perforation, and CD-related abdominal surgery, no significant association with diagnostic delay was observed. Older age at diagnosis, UGI involvement, and penetrating behavior are associated with long diagnostic delay in Korean CD patients. Moreover, diagnostic delay is associated with an increased risk of CD-related complications such as intestinal stenosis, internal fistulas, and perianal fistulas.

Introduction: The objective of this study was to evaluate associations between blood lead, cadmium, and mercury levels with estimated glomerular filtration rate in a general population of South Korean adults. Methods: This was a cross-sectional study based on data obtained in the Korean National Health and Nutrition Examination Survey (KNHANES) (2008-2010). The final analytical sample consisted of 5924 participants. Estimated glomerular filtration rate (eGFR) was calculated using the MDRD Study equation as an indicator of glomerular function. Results: In multiple linear regression analysis of log2-transformed blood lead as a continuous variable on eGFR, after adjusting for covariates including cadmium and mercury, the difference in eGFR levels associated with doubling of blood lead were -2.624 mL/min per 1.73 m Superscript-Two (95% CI: -3.803 to -1.445). In multiple linear regression analysis using quartiles of blood lead as the independent variable, the difference in eGFR levels comparing participants in the highest versus the lowest quartiles of blood lead was -3.835 mL/min per 1.73 m Superscript-Two (95% CI: -5.730 to -1.939). In a multiple linear regression analysis using blood cadmium and mercury, as continuous or categorical variables, as independent variables, neither metal was a significant predictor of eGFR. Odds ratios (ORs) and 95% CI values for reduced eGFR calculated for log2-transformed blood metals and quartiles of the three metals showed similar trends after adjustment for covariates. Discussion: In this large, representative sample of South Korean adults, elevated blood lead level was consistently associated with lower eGFR levels and with the prevalence of reduced eGFR even in blood lead levels below 10 {mu}g/dL. In conclusion, elevated blood lead level was associated with lower eGFR in a Korean general population, supporting the role of lead as a risk factor for chronic kidney disease.

Full Text Available Adult seroprevalence of HAV is decreasing in developed countries including South Korea, due to general sanitation improvement. Although hepatitis A vaccination was introduced in South Korea more than 20 years ago, recent infection rates have not decreased. In this study, we investigate the seroprevalence of anti-HAV IgG, and estimate the national disease burden of acute hepatitis A in adult population.Seroprevalence data were collected from health promotion center of Korea University Guro Hospital, in Seoul, Korea from 2010 to 2014. Data from adults (≥20-years being tested for anti-HAV IgG were included. In addition, epidemiological and clinical data of patients diagnosed with acute hepatitis A from 2009 to 2013, were collected from Korean Statistical Information Service (KOSIS and the National Health Insurance Service (NHIS database. Data were stratified and compared by age groups.A total of 11,177 subjects were tested for anti-HAV IgG from 2010 to 2014. Age-related seroprevalence showed relatively low seropositivity in young adults. Incidence of acute hepatitis A was highest in 2009 and lowest in 2013. When categorized by age group, adults in their 20s and 30s had more HAV infections and related-admissions than older adults. However, ICU admission rate and average insurance-covered cost was high in older adults.The anti-HAV IgG seropositivity in Korean younger adult population was low while the incidence of acute hepatitis A was high, especially in the 20-39 aged. However, a substantial number of older adults were infected, and required more intensive procedures and incurred higher insurance-covered medical costs.

Full Text Available This article introduces Korean women’s experience as seen through the lense of social and cultural backgrounds, from the premodern through to the postmodern era. Korean literature is used as a source to investigate Korean women’s experiences and perspectives. By means of feminist critique this article explores men-centered influences in Korean literature. It aims to illustrate the importance of the issue of female visibility through Korean literature from a Korean woman’s perspective. Two texts are analyzed and critiqued: the first is the myth of Korean origin. The second is a story of Gasi Gogi (a thorny fish. The article is intended to stimulate debate on gender, voices, and authority from a feminist perspective, in order to transcend the more traditional interpretations.

Full Text Available In this study, genetic analysis was conducted to investigate the association of angiotensin I converting enzyme (ACE gene polymorphism with clinical phenotype based on differentiation-syndrome of bronchial asthma patients. Differentiation-syndrome is a traditional Korean medicine (TKM theory in which patients are classified into a Deficiency Syndrome Group (DSG and an Excess Syndrome Group (ESG according to their symptomatic classification. For this study, 110 participants were evaluated by pulmonary function test. Among them, 39 patients were excluded because they refused genotyping. Of the remaining patients, 52 with DSG of asthma (DSGA and 29 with ESG of asthma (ESGA, as determined by the differentiation-syndrome techniques were assessed by genetic analysis. ACE insertion/deletion (I/D polymorphism analysis was conducted using polymerase chain reaction (PCR. Student's t, chi-square, Fisher and Hardy-Weinberg equilibrium tests were used to compare groups. No significant differences in pulmonary function were observed between DSGA and ESGA. The genotypic frequency of ACE I/D polymorphism was found to differ slightly between DSGA and ESGA (P = .0495. However, there were no significant differences in allelic frequency observed between DSGA and ESGA (P = .7006, OR = 1.1223. Interestingly, the allelic (P = .0043, OR = 3.4545 and genotypic (P = .0126 frequencies of the ACE I/D polymorphism in female patients differed significantly between DSGA and ESGA. Taken together, the results presented here indicate that the symptomatic classification of DSGA and ESGA by differentiation-syndrome in Korean asthma patients could be useful in evaluation of the pathogenesis of bronchial asthma.

The author in an attempt to evaluate hemodynamic changes in the clinical stages of Korean hemorrhagic fever measured plasma volume, cardiac output and effective renal plasma flow utilizing radioisoto as during various phases of the disease. Cardiac output was measured by radiocardiography with external monitoring method using RIHSA. Effective renal plasma flow was obtained from blood clearance curve drawn by external monitoring after radiohippuran injection according to the method described by Razzak et al. The study was carried out in thirty-eight cases of Korean hemorrhagic fever and the following conclusions were obtained. 1) Plasma volume was increased in the patients during the oliguric and hypertensive-diuretic phases, while it was normal in the patients during the normotensive-diuretic phase. 2) Cardiac index was increased in the patients during the oliguric phase and was slightly increased in the patients at the hypertensive diuretic phase. It was normal in the other phases. 3) Total peripheral resistance was increased in the hypertensive patients during diuretic phase, while it was normal in the rest of phases. 4) Effective renal plasma flow was significantly reduced in the patients during the oliguric and diuretic phases as well as at one month after the oliguric onset. There was no significant difference between the oliguric and the early diuretic phases. Renal plasma flow in the group of patients at one month after the oliguric onset was about 45% of the normal, however, it returned to normal level at six months after the onset. 5) Clinical syndrome of relative hypervolemia was observed in some patients during the oliguric phase or hypertensive diuretic phase. Characteristic hemodynamic findings were high cardiac output and normal to relatively increased peripheral resistance these cases. Relatively increased circulating blood volumes due to decreased effective vascular space was suggested for the mechanism of relative hypervolemia. 6) Cardiac

The study investigated the roles of social support, self-efficacy, and behavioral change in physical activity (PA) in the Korean culture. The subjects were 164 Korean college students. In November 2016, the study participants completed an online survey asking about PA behavior, PA Self-Efficacy, PA Stages of Change (stages of behavioral change in PA), and Social Support for PA. The collected data were statistically analyzed through structural equation modeling. In the results, PA Stages of Change had a direct effect ( β  = 0.57, p  Change as PA Self-Efficacy had a direct effect ( β  = 0.50, p  Change. However, Social Support for PA did not show an effect on other factors. Additionally, Social Support for PA had a correlation of r  = 0.45 ( p  Change is a significant PA predictor. Moreover, high PA Self-Efficacy indirectly helps Korean young adults to be more physically active by fostering advancement on the stages of behavioral change in PA. In contrast, Social Support for PA does not have a significant association with PA or PA Stages of Change. This non-significance of Social Support for PA can be explained with Korea's collectivistic culture. Furthermore, there is a possibility that Social Support for PA can positively affect PA by interacting with PA Self-Efficacy.

Dietary factors are closely associated with the risk of non-alcoholic fatty liver disease (NAFLD). Asian and Western diets differ in energy-nutrient composition, fatty-acid composition, and main nutritional sources; therefore, the implications would be limited if the Western-oriented study results were applied to Asian patients. We aimed to identify the nutrient and food group intakes of a typical Asian diet and assess their effects on NAFLD risk. In total, 348 subjects were recruited from 5 participating hospitals. Information on sociodemographic characteristics and health-related behaviors were obtained through face-to-face interviews. NAFLD was diagnosed by ultrasound. Dietary intakes were assessed with a 24-h recall applying a multiple-pass approach and 4-day food records that included 1 or 2 weekend days. There were no significant differences in health-related behaviors between the cases and controls except for smoking behavior. The cases had elevated triacylglycerol, fasting glucose, and low-density lipoprotein cholesterol levels compared with the controls. In men, after adjusting for variables, low intakes of vitamin C (odds ratio [OR], 4.23), vitamin K (OR, 3.93), folate (OR, 3.37), omega-3 fatty acids (OR, 2.16), and nuts and seeds (OR, 3.66) were associated with a significantly higher risk for developing NAFLD. In women, vitamin K (OR, 2.54) and vegetable (OR, 4.11) intakes showed a significant beneficial effect for lowering NAFLD risk. Adequate intakes of vitamin C, vitamin K, folate, omega-3 fatty acids, nuts and seeds, and vegetables may help in preventing NAFLD in Korean adults.

BACKGROUND. Silent peptic ulcer has been considered to be associated with nonsteroidal anti-inflammatory drug (NSAID). The recent studies have reported no relationship between them. AIM. We attempted to investigate an association between asymptomatic peptic ulcer and NSAID in Korean adults. METHODS. The subjects were enrolled from participants visiting Myongji Hospital for health examination program of the Korean National Health Insurance Corporation. The questionnaires were designed to investigate individual medical information and gastroduodenal symptoms. RESULTS. From May 2005 to March 2009, 5459 participants were enrolled and 299 participants were excluded. Of 5160 participants, 3144 (60.9%) participants were asymptomatic and 424 (8.2%) participants had peptic ulcer. Among 3144 asymptomatic participants, NSAID-taking participants had the odds ratio of 1.4 [95% confidence interval (CI): 0.7-2.6, p = 0.339] for the risk of peptic ulcer. Among 424 peptic ulcer patients, 247 (58.3%) were asymptomatic. They had lower prevalence of NSAID use (4.9% vs. 14.7%). The asymptomatic gastric ulcer patients had smaller size and more frequent healing stage than the symptomatic gastric ulcer patients. In multivariable analysis of 424 peptic ulcer patients, NSAID patients had the odds ratio of 0.249 (95%CI: 0.115-0.536, p < 0.05) for asymptomatic peptic ulcer. In subgroup analysis of 284 gastric ulcer patients, NSAID-taking patients had the odds ratio of 0.263 (95% CI: 0.105-0.657, p = 0.004) for asymptomatic peptic ulcer. CONCLUSION. NSAID has an inverse association with asymptomatic patients with gastric peptic ulcer, but has no association with gastroduodenal symptoms in duodenal ulcer patients. These suggest that NSAID may be associated with gastroduodenal symptoms rather than masking symptoms, at least in gastric ulcer patients.

Backpack palsy (BPP) is a common aetiology of brachial plexopathy in military hospitals. We aimed to determine the incidence and risk factors of BPP in young Korean soldiers. We identified enlisted patients who were diagnosed with BPP from a review of the medical records of all the Korean military hospitals in 2011 and 2012 and investigated their clinical findings and medical study results. To identify risk factors of BPP, we also surveyed, by questionnaire, healthy recruits of a company in a training centre who had just finished night marches. We divided them according to whether they had paresthaesia and/or weakness in their arm(s) during marching and compared their characteristics. The incidence of BPP in Korean soldiers was 29.7 per 100,000 person-years (95% CI 17.2 to 24.3). Body mass index (BMI) was significantly lower in patients with BPP than it was in healthy recruits. Among healthy recruits, those who had experienced paresthaesia and/or weakness during marching had a significantly lower BMI than did those who had not. We report the incidence of BPP in young Korean soldiers. A low BMI was a risk factor for BPP. These results may be helpful in establishing a strategy for the prevention of BPP in the setting of military training. Published by the BMJ Publishing Group Limited.
