    Perceived smoking prevalence, a strong predictor of actual smoking behavior, may be influenced by the ethnicity and gender of the reference group presented to Korean American emerging adults. Self-identifying Korean and Korean Americans aged 18-25 (N = 475), were invited to complete a 15-20 min online survey about their attitudes towards smoking. Predictors of perceived smoking prevalence were evaluated separately for four reference groups: Caucasian Americans, Korean Americans in general, Korean American men, and Korean American women. Respondents' smoking status was associated with perceived smoking prevalence for all reference groups except Caucasian Americans, even among light smokers. Father's smoking status was associated with perceived smoking prevalence for Korean American men, only among females respondents. Findings suggest that ethnicity and gender of both the reference group and respondents influence smoking rate estimates. Tailoring intervention content to the target population's gender and ethnicity may be a way to enhance smoking prevention strategies. PMID:27075031

    Suicidal ideation increases the risk of suicide. This study investigated the age-specific contributions of sociodemographic factors, health status, and health behaviors to suicidal ideation using nationally representative data. The factors associated with suicidal ideation differ by age. Perceived bad health, stress, and depression had a significant influence on suicidal ideation in all age groups, but their specific effects differed in different age groups. The influence of perceived bad health increased with age, and the effect of stress was strongest among those aged 45-64 years. Moreover, the effect of being depressed decreased by age and was strongest among those 20-44 years of age. Disease and marital status did not have a significant effect on suicidal ideation among those 45-64 years old, and education had no effect among those 65 years or older. PMID:25833725

    International Nuclear Information System (INIS)

    A one day representative mixed diet of an adult Korean was collected from the data based on the food intake of 108 healthy subjects between the ages 20 and 50. Sampling for the Korean total diet was carried out by using a market basket study based on the Korean standard food consumption scheme reported by the Korean Nutriting Society. Average consumption frequency of different food items for a one day representative mixed diet of an adult Korean and the amount of each item to prepare a one day Korean representative total diet are surveyed. The analytical methods involve both instrumental and radiochemical neutron activation techniques develop for the determination of the elements Cs, I, Sr, Th and U in various kinds of food samples. Concentrations of trace elements including 5 important elements for radiological protection, U, Th, Cs, Sr and I in the Korean total diet and the 4 most frequently consumed Korean foodstuffs have been analyzed by neutron activation analysis. Detection limits for U, Th, Sr and I were improved to ppb levels by radiochemical separation after neutron irradiation. Five biological NIST reference materials were also analyzed for quality control of the analysis. Seventeen trace elements in the Korean total diet and four Korean representative foodstuffs were also analyzed quantitatively by instrumental neutron activation analysis. (author)

    We established the timing of peak bone mass acquisition and body composition maturation and provide an age- and sex-specific body composition and bone density reference database using dual-energy X-ray absorptiometry in Korean subjects 10-25 years of age. Reference percentiles and curves were developed for bone mineral content (BMC), bone mineral density (BMD) of the whole body, the lumbar spine, and the femoral neck, and for fat mass (FM) and lean mass (LM) of 1969 healthy participants (982 males) who participated in the 2009-2010 Korean National Health and Nutrition Examination Survey. Additionally, bone mineral apparent density (BMAD), FM index, and LM index were calculated to adjust for body size. BMC and BMD at all skeletal sites as well as LM increased with age, reaching plateaus at 17-20 years of age in females and 20-23 years of age in males. The femoral neck was the first to reach a bone mass plateau, followed by the lumbar spine and then the whole body. Spine BMAD increased with age in both sexes, but femoral and whole-body BMAD remained the same over time. Females displayed a dramatic increase in FM during puberty, but the FM of males decreased until mid-puberty. These findings indicate that bone health and body composition should be monitored using a normal reference database until the late second to early third decade of life, when statural growth and somatic maturation are completed.

    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. PMID:26449129

  1. Cadmium exposure induces hematuria in Korean adults

    International Nuclear Information System (INIS)

    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; Ptrend=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

    2016-01-01

    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. PMID:26988086

    2014-06-01

    Full Text Available The purpose of the current study was to test a model of socialization among a sample of adult Korean adoptees. Based on the tenants of homophily and social identity theory, it was hypothesized that participants’ early racial and ethnic socialization experiences would account for their current intragroup friendships as adults, and that this relationship would be mediated by early intragroup contact and moderated by early ethnic identity status. The two ethnic and racial socialization variables (i.e., ethnic heritage activities and racial in-exposure significantly accounted for participants’ relationships with other Korean adoptees and nonadopted Koreans, and the effects were partially explained by early intragroup contact. Results of multigroup testing indicated the proposed socialization model was non-invariant across groups, such that the effects of ethnic heritage activities on intragroup contact and the effect of racial in-exposure on friendships with Korean adoptees were significantly different based on early ethnic identity status.

    2015-05-01

    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.

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.

    Photovoice was used to understand the impact of childhood cancer on Korean young adult survivors. Seven survivors of childhood cancer (currently aged 20-27 years), diagnosed before the age of 19 and with cancer treatment completed, participated in five sessions. The participants took photographs that captured their group's weekly topics and participated in discussions about their feelings and experiences. Fifty-six photo images with narratives on the survivors' experiences were produced on these four participant-selected themes: Relationships With Others, Stigma, Overcoming Difficulties, and The Future This study on Korean childhood cancer survivors sheds light on their perspectives about the impact of cancer. Using an innovative methodology that takes the participants' point of view, this study contributes to the literature on young adult cancer survivors' quality of life and their psychosocial adjustment. The results can inform educational programs and increase public awareness by providing survivors' schoolteachers and peers with knowledge about childhood cancer. PMID:26265716

    [Purpose] This study was performed to determine whether certain lifestyle factors are associated with hypertension in community-dwelling Korean adults. [Subjects and Methods] The subjects were 586 males and 1,135 females > 20 years old who had visited a public health promotion center in Seoul, Republic of Korea to take a survey related to lifestyle factors. Hypertension status was defined according to the criteria of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure VII report. [Results] The relationships between lifestyle factors and hypertension status were assessed using multivariate logistic regression analysis after adjusting for age and gender. Only mental stress and economic status significantly predicted hypertension status. [Conclusion] We conclude that sleep duration, education level, frequency of drinking and smoking status were not associated with hypertension status. However, economic status and mental stress were significantly associated with hypertension in community-dwelling Korean adults, regardless of age or gender. PMID:26834333

    Full Text Available 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.

    International Nuclear Information System (INIS)

    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.

    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.

  5. A radiological study on the degenerative joint disease of the lumbar spine in Korean adult men below the age of forty

    International Nuclear Information System (INIS)

    It is generally believed that this disease is a degenerative process, a part of the general phenomena, hastened by excessive functional demand and a decreasing efficiency of blood supply. Though degenerative joint disease is the commonest of all ailments, its manifestations do not appear as a rule until the fourth or fifth decade, and it is not always easy to diagnose because we know less about it than about many less common types. Little information is available on its frequency in person below the age of forty. The present study was designed to obtain more precise information about development of this disease in person below the age of forty. After a detailed clinical examination, x-ray findings of a total of 566 men with low back pain checked at the Department of Radiology, National Public Hospital from Jan. 1976 to Dec. 1978 were received. The following result were obtained: 1. 111 (19.6%) of the 566 men had radiologic evidence of degenerative disease in lumbar spine. The degenerative joint disease first appeared on the age of 26. The degenerative joint disease was found in 16 (14.9%) of the 107 men between 25 and 29 years old, 14 (16.3%) of the 86 men between 35 and 39 years old, 31 (27.4%) of the 113 men between 35 and 39 years old, and 50 (50%) of the 100 between 40 and 44 years old. 2.The 4th lumbar spine was most commonly involved, being in 82.0% of the cases, and less frequent sites were the 5th lumbar spine (67.6%), the 3rd lumbar spine (51.3%), the 2nd lumbar spine (18.9%) and the 1st lumbar spine (3.6%). 38 (28.8%) of the 111 cases revealed single level involvement, but 79 (71.2%) cases showed multiple level involvement with the highest incidence at 14 and 15. 3. 111 cases of the 566 revealed marginal spurring. Bridging was noted in 8 cases, space narrowing 8 cases, and eburnation 7 caes.

    2010-12-01

    This paper is a study of the growth status of 1406 North Korean refugee children and adolescents who were between 6 and 19.9 years of age at the time of their arrival in South Korea, during the years 1995-2007, as compared with that of their South Korean peers. Refugee children of 6.5 years of age were found to be taller and heavier than North Korean children of the same age residing in North Korea. On the other hand, all of the North Korean refugee boys and girls were shorter and weighed less than their South Korean peers. This disparity in height and weight growth status was smallest during the pre-teen years and then began to increase, peaking in the mid-teen years and decreasing in the late-teen years, with the late-teen disparity being still larger than the pre-teen one. This pattern of disparity suggests that the greatest gap observed in mid-teen years was caused by differences in growth tempos during the period of pubertal growth and that the final differences in body size between the North and South Korean adults were partly pubertal in origin. The mean height-for-age z-score (HAZ) and weight-for-age z-score (WAZ) of the North Korean refugee boys were significantly lower than those of the North Korean refugee girls, indicating that the girls' growth status was better than that of the boys. In addition, the WAZ of the North Korean refugee children and adolescents was higher than their HAZ, indicating that their growth in height is poorer than that of weight. A regression analysis revealed that the mean HAZ of North Korean refugee children and adolescents born between 1995 and 1999, a period during which North Korea suffered a famine, was not statistically significantly lower than that of those born earlier. The time that the North Korean children and adolescents spent outside of North Korea before entering South Korea was discovered to have had a positive effect on their growth status, suggesting that they experienced some degree of catch-up growth while

  9. In vivo organ mass of Korean adults obtained from whole-body magnetic resonance data

    International Nuclear Information System (INIS)

    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)

    This study investigates the sex lives of Korean older adults (i.e., those over 60 years) and attempts to identify gender-related factors influencing sexual satisfaction. It used data from the 2008 Korean National Survey on Older Adults conducted by the Ministry of Health, Welfare, and Families. Of the 15,146 individuals who had taken part in the 2008 study, secondary analysis was conducted with data from 3360 persons who had spouses and were willing to respond to sex-related questions in a face-to-face interview. The mean age of male and female subjects was 67.34 and 66.86 years respectively. In the male subjects, sexual frequency, followed by marital satisfaction and cognitive function, had the greatest effect on sexual satisfaction. These three variables together accounted for 21% of the male subjects' sexual satisfaction. In the female subjects, marital satisfaction, followed by frequency of sexual activity, absence of depressive symptoms, age, and length of cohabitation with spouse, had the greatest effect on sexual satisfaction. These five variables together explained 11% of their sexual satisfaction. This study indicates that sexual frequency and physical factors have the most important effects on the sex lives of older men, while older women value psychosocial and relational factors more highly. Therefore, interventions aiming to improve sexual satisfaction in older adults should take gender differences into account. PMID:23153985

    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.

  19. Development of a Korean adult male computational phantom for internal dosimetry calculation

    International Nuclear Information System (INIS)

    A Korean adult male computational phantom was constructed based on the current anthropometric and organ volume data of Korean average adult male, and was applied to calculate internal photon dosimetry data. The stylised models of external body, skeleton, and a total of 13 internal organs (brain, gall bladder, heart, kidneys, liver, lungs, pancreas, spleen, stomach, testes, thymus, thyroid and urinary bladder) were redesigned based on the Oak Ridge National Laboratory (ORNL) adult phantom. The height of trunk of the Korean phantom was 8.6% less than that of the ORNL adult phantom, and the volumes of all organs decreased up to 65% (pancreas) except for brain, gall bladder wall and thymus. Specific absorbed fraction (SAF) was calculated using the Korean phantom and Monte Carlo code, and compared with those from the ORNL adult phantom. The SAF of organs in the Korean phantom was overall higher than that from the ORNL adult phantom. This was caused by the smaller organ volume and the shorter inter-organ distance in the Korean phantom. The self SAF was dominantly affected by the difference in organ volume, and the SAF for different source and target organs was more affected by the inter-organ distance than by the organ volume difference. The SAFs of the Korean stylised phantom differ from those of the ORNL phantom by 10-180%. The comparison study of internal dosimetry will be extended to tomographic phantom and electron source in the future. (authors)

    We wanted to measure the vascular pedicle width (VPW) in normal Korean adults and correlate the VPW with the body physique and we also wanted to establish the index for normal VPWs, which could be utilized in reading chest PAs. We VPW was measured on the posteroanterior (PA) chest radiographs of 262 normal Korean adults (134 men and 128 women, age range: 22-88 years, mean age: 45.2 years), who visited the hospital for a general health examination. The relationship between the VPW and the height and the Body Mass Index (BMI) was evaluated. Correlations between height and the thoracic spine length (TSL) and between the BMI and the lateral chest wall thickness (CWT) were analyzed as well. The mean VPW was 47.4 ({+-} 6.4) mm. The VPW was positively correlated with the height ({rho} < 0.01) and the BMI ({rho} < 0.01) of the subject. The patient's height was well correlated with the TSL, and the BMI was correlated with the CWT (r = 0.75, r = 0.76). The table for the normal VPWs according to patient's TSL and CWT was established. By measuring the TSL and the CWT on chest PA, which reflect the height and BMI, respectively, and by utilizing the provided table for the normal VPW, we can determine the normality of a patient's VPW.

    Benzophenone (BP) derivatives are widely used in personal care products (PCPs) for protection from ultraviolet radiation. Because of their broad applications, BP derivatives have been found in various human bodily fluids. In the present study, we investigated the relationship between urinary concentrations of BP derivatives and PCP use in Korean adults. A urinary BP biomonitoring survey was conducted in Korea by the Ministry of Food and Drug Safety in 2014. BP derivatives (BP-1, BP-3, and 4-OH-BP) were measured in urine samples from 168 Korean adults (mean age, 43.2 ± 15.4 years) by high-performance liquid chromatography coupled with triple quadrupole tandem mass spectrometry. Information about the use of PCPs in the past 7 days was obtained by direct interviews. The mean levels of BP-1, BP-3, and 4-OH-BP were 0.87, 5.87, and 0.13 ng/g creatinine, respectively. The geometric mean levels of BP-1, BP-3, and 4-OH-BP were significantly higher in female than those in male. The medians of the urinary concentration of BP derivatives were significantly higher among users of the following PCPs than those in non-users; the PCPs included sunscreen, skin care products, functional cosmetics, makeup base, makeup, lip cosmetics, eye cosmetics, color cosmetics, perfume products, and nail products. A regression analysis revealed a significant linear association between urinary BP-3 concentrations and the number of additional cosmetic products used. These findings provide evidence of a positive association between exposure to PCPs and urinary BP derivative concentrations in Korean adults. PMID:26626599

    To compare the reliability of the Greulich-Pyle (GP) method, Tanner-Whitehouse 3 (TW3) method and Korean standard bone age chart (KS) in the evaluation of bone age of prepubertal healthy Korean children. Left hand-wrist radiographs of 212 prepubertal healthy Korean children aged 7 to 12 years, obtained for the evaluation of the traumatic injury in emergency department, were analyzed by two observers. Bone age was estimated using the GP method, TW3 method and KS, and was calculated in months. The correlation between bone age measured by each method and chronological age of each child was analyzed using Pearson correlation coefficient, scatterplot. The three methods were compared using one-way analysis of variance. Significant correlations were found between chronological age and bone age estimated by all three methods in whole group and in each gender (R2 ranged from 0.87 to 0.9, p < 0.01). Although bone age estimated by KS was slightly closer to chronological age than those estimated by the GP and TW3 methods, the difference between three methods was not statistically significant (p > 0.01). The KS, GP, and TW3 methods show good reliability in the evaluation of bone age of prepubertal healthy Korean children without significant difference between them. Any are useful for evaluation of bone age in prepubertal healthy Korean children.

    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. PMID:22125682

    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 consumption of 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. PMID:26240489

    Frailty has been previously studied in Western countries and the urban Korean population; however, the burden of frailty and geriatric conditions in the aging populations of rural Korean communities had not yet been determined. Thus, we established a population-based prospective study of adults aged ≥ 65 years residing in rural communities of Korea between October 2014 and December 2014. All participants underwent comprehensive geriatric assessment that encompassed the assessment of cognitive and physical function, depression, nutrition, and body composition using bioimpedance analysis. We determined the prevalence of frailty based on the Cardiovascular Health Study (CHS) and Korean version of FRAIL (K-FRAIL) criteria, as well as geriatric conditions. We recruited 382 adults (98% of eligible adults; mean age: 74 years; 56% women). Generally, sociodemographic characteristics were similar to those of the general rural Korean population. Common geriatric conditions included instrumental activity of daily living disability (39%), malnutrition risk (38%), cognitive dysfunction (33%), multimorbidity (32%), and sarcopenia (28%), while dismobility (8%), incontinence (8%), and polypharmacy (3%) were less common conditions. While more individuals were classified as frail according to the K-FRAIL criteria (27%) than the CHS criteria (17%), the CHS criteria were more strongly associated with prevalent geriatric conditions. Older Koreans living in rural communities have a significant burden of frailty and geriatric conditions that increase the risk of functional decline, poor quality of life, and mortality. The current study provides a basis to guide public health professionals and policy-makers in prioritizing certain areas of care and designing effective public health interventions to promote healthy aging of this vulnerable population.

    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 periodontitis. In conclusion, excessive consumption of green tea may be considered as a risk factor for periodontal disease among Korean adults. PMID:27384581

    Background and Objectives Left ventricular diastolic dysfunction is known to be a marker of myocardial damage, in particular myocardial fibrosis resulting from hypertension (HT). However, few studies have shown an association between the grade of diastolic dysfunction and blood pressure classification. We investigated the association between diastolic dysfunction and prehypertension (preHT) in apparently healthy adults who underwent routine health examinations. Subjects and Methods The study sample included 4261 Koreans, 45 to 64 years of age with no previous history of HT, diabetes mellitus, malignancy, proven coronary artery disease, or valvular heart disease based on echocardiography, who underwent routine health examinations including echocardiography. The subjects were classified into three groups based on resting blood pressure: prehypertensive, hypertensive, and normotensive. Results The prevalence of preHT in our study was 42.1%. After adjusting for age, gender, smoking status, alcohol consumption, fasting blood sugar, serum lipid profile, and body mass index, left ventricular diastolic dysfunction grades 1 and 2 were significantly more frequent in subjects with preHT (odds ratio [OR] 1.66 [95% confidence interval {CI} 1.40-1.96] and 1.37 [95% CI 0.95-1.97], respectively). When analyzed according to gender, the increased OR was especially notable in males. Conclusion Left ventricular diastolic dysfunction appears to be significantly associated with preHT in Korean middle-aged males. PMID:27482263

    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.

    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.

A comparison was made between successful quitters and those who failed to quit after attempts to stop smoking.A total of 7,839 males, aged 19-65 years, were included in this cross-sectional study. The outcome measures were the success and failure rates in smoking cessation, sociodemographic and clinical characteristics, health behaviors, perceived health status, quality of life, and mental health. Multiple logistic regression analyses were used to examine the various factors associated with smoking cessation success.The cessation success and failure rates were 45.5% and 54.5%, respectively. Smoking cessation was related to older age, marriage, higher income, smoking larger amounts of cigarettes, use of willpower, alcohol abstinence, cancer history, better mental health, and higher levels of quality of life, after controlling for multiple variables. Second-hand smoke exposure at home and using nicotine replacement therapy were associated with a lower likelihood of smoking cessation.A smoke-free environment, use of willpower, alcohol abstinence, and better stress management are important for smoking cessation. Unlike previous studies, not using nicotine replacement therapy and higher levels of daily cigarette consumption were associated with successful smoking cessation, suggesting that motivation appears to be important to smoking cessation in Korean adult male population.

    The aims of this study were to identify the distribution of coronary artery calcium score (CACS) by age group and cardiovascular (CV) risk factors and to evaluate the association between CV risk factors and CACS classification in asymptomatic adults. The study included 31,545 asymptomatic Koreans, over 20 years of age with no previous history of malignancy, proven coronary artery disease, or stroke, who underwent CACS computed tomography at the Health Promotion Center, Samsung Medical Center, between January 2005 and June 2013. Mean (±SD) age was 53.8 (±8.5) years overall, 56.1 (±8.3) in men, and 53.3 (±8.5) in women. They were classified into five groups based on their resting CACS: none (CAC = 0), minimal (0  CAC). Older age groups exhibited higher CACS values. The proportion of CACS classification in our study was 55.5 % with no CACS, 9.5 % with minimal CACS, 19.8 % with mild CACS, 10.8 % with moderate CACS, and 4.3 % with extensive CACS. Adjusted odds ratios (ORs) were calculated for CV risk factors to determine their association with CACS. When analyzed according to sex, in males, the adjusted OR for CACS increased with the presence of hypertension (HT), diabetes mellitus (DM), obesity, chronic kidney disease, and smoking status. While, in females, the adjusted OR for CACS increased with the presence of HT, DM, and obesity. CV risk factors appear to be significantly associated with CACS in the Korean population.

    Absorbed fraction (AF) and specific absorbed fraction (SAF) are crucial values for the calculation of radionuclide S-values and consequently for internal dose estimates. The formalism of the Medical Internal Radiation Dose (MIRD) committee of the Society of Nuclear Medicine (SNM) has been utilised as a standard in the calculation of individual organ doses for biologically distributed radionuclides and for different types of radiation. Although those quantities are highly sensitive to individual anatomical difference, the SAF dataset calculated by Caucasian-based stylised phantoms have been applied to Korean population until now. This study was intended to calculate the SAFs by using realistic Korean voxel phantom and Monte Carlo transport technique for the first time and compare the results with those of the existing Caucasian-based data and the Korean stylised phantom published recently. The up-to-date realistic Korean voxel phantom, KTMAN-2, which was developed from computed tomography (CT) images of an average Korean adult male, was employed for Monte Carlo calculation using EGSnrc user-code, developed for the purpose of this study. The SAFs for 32 target organs and tissues from the photon source, uniformly deposited in a total of 37 source organs and tissues, were calculated from KTMAN-2. The results were compared with those for an adult phantom of Oak Ridge National Laboratory (ORNL) and Korean adult stylised phantom. Two major reasons of discrepancy were analysed: (1) racial difference between the Korean and the Caucasian and (2) anatomical difference between stylised and voxel phantoms. When the source organ was identical to the target organ, difference in SAF caused by the difference in target-organ mass between the Korean and the Caucasian phantoms was mainly observed. When the source and target organs were not identical, significant difference in SAF was observed which was mainly attributed to the difference in inter-organ distance and organ shape between

  7. S-value of Radioiodine(131I) in Korean Reference Adult Male

    International Nuclear Information System (INIS)

    In order to better understand the effects of absorbed radioiodine upon Korean reference adult male, a mathematical phantom representation was contrived based on composite data of the physiology of Korean reference adult male. Using this, S-values of radioiodine() per each organ were calculated. The calculated S-values were compared to the existing data described in the TM-8381 report of ORNL calculated on the basis of an ICRP-23 reference male. The results indicated that S-values were higher for the phantom based on Korean reference adult male. The results of this study illustrate that, while the bio-chemical constitution of each source and target organ of the torso are important, the relative location of the organs and characteristics of the radionuclides also exert important influences.

    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.

    The stop systems of adult Korean (L1)-English (L2) bilinguals were studied through acoustic analysis of Korean and English stop productions. The interaction of the first and second language stop systems was investigated as a function of age of exposure to English. The main goals of the investigation were to examine the extent to which early and the late bilinguals produced a given stop category in a native-like way and the extent to which the two stop systems were held independent from each other in the phonological systems of the bilinguals. Two specific questions were asked: whether early bilinguals were more native-like in the production of English stops and thus were more likely to establish L2 phonetic categories than late bilinguals, and whether the Early bilinguals maintain a greater extent of independence between the Korean and English stop systems than the late bilinguals. For this purpose, productions of Korean and English stops were analyzed in terms of three acoustic-phonetic properties, VOT, H1-H2, and f0. The results suggested that fine-grained phonetic information is crucial to investigation of bilingual phonological systems and they were discussed in terms of the role of perceived phonetic distance between L1 and L2 phonetic categories in L2 speech learning.

  10. Tracheal measurement by computed tomography in Korean adults

    International Nuclear Information System (INIS)

    The knowledge of normal tracheal morphology is helpful during endotracheal intubation for anesthesia as well as detecting tracheal and paratracheal disorders. Tracheal measurement by simple X-ray is not accurate due to image imagnification and overlapping of the shoulders in the lateral projection. CT, however, is highly accurate to measure the normal tracheal morphology and paratracheal anatomy. The study was undertaken to obtain standard values of normal Korean tracheae. Healthy cases of 50 males and 50 females who had no neck and mediastinal pathology or respiratory difficult were selected. The trachea was measured by CT. The results were as follows: 1. Tracheal lengths were 126.1mm (SD 11.6) in males and 116.0mm (SD 8.4) in females. 2. AP diameters of trachea were 18.9mm (SD 2.1) in males and 15.5mm (SD 1.3) in females. The transverse diameters were 17.7mm (SD 1.9) in males and 15.3mm (SD 1.2) in females. 3. Tracheal cross-sectional areas were 288mm2 (SD 54) in males and 204mm2 (SD 31) in females. Mean cross-sectional area of level 4 was greater in 16.6% than that of level 1. 4. Tracheal cross-sectional areas and diameters were dependent on sex but not on weight and height. And cross-sectional areas and AP diameters were positively correlated with age in male. 5. The shape of the trachea showed that the ovoid shape was most common at the level 1, the C-shape was most common at the level 2 and 3, horizontal oval or D-shape were more common at the level 4.

    Background We examined the relationship between vitamin D status and health-related quality of life, and explored other related factors in the general Korean population. Methods We used data from the 2007–2012 Korea National Health and Nutrition Examination Survey on 14,104 adults, aged 20–49 years, who had consented to serum vitamin D measurement and answered health-related quality of life questions. EuroQol-5 was used for measurement. Serum vitamin D levels were measured at intervals of 0–9.99, 10–19.99, 20–29.99, and ≥30 ng/mL. Results Participants with higher serum vitamin D (serum 25-hydroxyvitamin D) levels were significantly less likely to report problems with depression and anxiety. After adjustment for age, gender, income level, education level, marital status, alcohol consumption, smoking status, and the existence of depressive disorders, the odds ratio for reporting a problem with depression and anxiety was 0.60 (95% confidence interval [CI], 0.39–0.91). The odds ratio for the prevalence of any problem was 0.69 (95% CI, 0.53–0.89) before adjustment, but was not statistically significant after adjustment. No significant associations were observed for problems with mobility, self-care, usual activity, or pain and discomfort. Conclusion This is the first study to examine the associations between vitamin D and health-related quality of life for the general Korean population. Vitamin D status was not significantly associated with the dimensions of EuroQol-5 except for depression and anxiety problems. PMID:27468340

    Previously, genetic polymorphisms of C12orf51 (HECTD4) (rs2074356 and/or rs11066280) have been shown to be related to alcohol consumption and type 2 diabetes (T2D). This study aimed to prospectively examine whether C12orf51 had an interaction with or independent effect on alcohol consumption and the risk of T2D. The present study included 3,244 men and 3,629 women aged 40 to 69 years who participated in the Korean Genome and Epidemiology Study (KoGES)_Ansan and Ansung Study. Cox proportional hazards models were used to estimate HRs and 95% CIs for T2D. rs2074356 and rs11066280 were associated with the risk of T2D after adjusting for alcohol consumption (rs2074356 for AA: HR = 0.39 and 95% CI = 0.17-0.87 in men, and HR = 0.36 and 95% CI = 0.13-0.96 in women; rs11066280 for AA: HR = 0.44 and 95% CI = 0.23-0.86 in men, and HR = 0.39 and 95% CI = 0.16-0.94 in women). We identified that the association of each variant (rs2074356 and rs11065756) in C12orf51 was nearly unchanged after adjusted for alcohol consumption. Therefore, the association of 2 SNPs in C12orf51 with diabetes may not be mediated by alcohol use. There was no interaction effect between alcohol consumption and the SNPs with T2D. However, even in never-drinkers, minor allele homozygote strongly influenced T2D risk reduction (rs2074356 for AA: HR = 0.35, 95% CI = 0.14-0.90, and p-trend = 0.0035 in men and HR = 0.34, 95% CI = 0.13-0.93, and p-trend = 0.2348 in women; rs11066280 for AA: HR = 0.36, 95% CI = 0.16-0.82, and p-trend = 0.0014 in men and HR = 0.39, 95% CI = 0.16-0.95, and p-trend = 0.3790 in women), while alcohol consumption did not influence the risk of T2D within each genotype. rs2074356 and rs11066280 in or near C12orf51, which is related to alcohol drinking behavior, may longitudinally decrease the risk of T2D, but not through regulation of alcohol consumption.

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the dentofacial relationship of the Korean adult females who had excellent profile using roentgenocephalometry. The subjects were 35 females from 18 to 24 years of age selected among the professional models, beauty contest winners and performing stars. And, as the control group, 37 females from 18 to 23 years of age with normal occlusion and acceptable profile were selected. In both groups, each variable was measured and evaluated statistically introducing 24 reference points, 22 reference lines and 17 reference angles respectively. Conclusion from this study were as follows: 1. There was no significant difference between the two groups. But SNA and convexity angle which had indicated the maxillary protrusion were lesser in the professional models, beauty contest winners and performing stars than in the control group. 2. In the professional models, beauty contest winners and performing stars, the maxillary and mandibular incisors were more upright than in the control group. 3. The protrusion of the upper and lower lip was lesser in the professional models, beauty contest winners and performing stars than in the control group. 4. Professional models, beauty contest winners and performing stars revealed more straight profile than the control group and were similar to that of the Caucasian. 5. Generally, it was the tendency that the straight profile was accepted as esthetics.

    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.

  18. Assessment of breathing rate of adult Korean for use in internal dosimetry

    International Nuclear Information System (INIS)

    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 2.3x104L/day which well agrees with the value given in ICRP 23

  19. Study on the Correlation between PSR and Korean Stress Test for Continued Operation of Aging NPP

    International Nuclear Information System (INIS)

    Nuclear Safety and Security Commission (NSSC), Korean nuclear regulatory authority established the stress test guideline based on the EU stress test, and KHNP prepared the execution plan in response to the guideline for the CO of Kori Unit 1 and Wolsong Unit 1. PSR is a comprehensive safety review program for long term operation of NPP, which was developed by IAEA. Korea adopted PSR in 1999 as the regulatory requirement for CO of NPP. The IAEA standard guideline for PSR program was updated in 2003. However, the Korean PSR has not been revised yet to apply the new IAEA guidelines. Additionally, national legal systems and guidelines associated with the adoption of stress tests are urgently required as well. These revisions are imperative in order to ensure the reliability of NPPs, and to promote public acceptance and understanding. This study presents the technical basis and proposals for review actions necessary to address the issues and controversies surrounding the continued operation and decommissioning of aging NPPs in Korea. As discussed earlier in characteristics of Korean Stress Test, it is more comprehensive than the EU Stress Test in terms of its multilateral evaluation which includes equipment durability, plant operation, human factors, and safety margins, hence substantially raising the significance and value of the evaluation process. Thus, the addition of Korean Stress Test to the existing Korean Evaluation of CO is expected to greatly increase the quality of safety assessment of aging NPPs in Korea due to its stricter safety policies, hence providing a more meaningful evaluation process. However, a one-time application of the Korean Stress Test to only Kori Unit 1 and Wolsong Unit 1 would be a waste of the great effort that has been done thus far to improve the Korean Evaluation of CO and develop the Korean Stress Test. By extending the Korean Stress Test to all NPPs in Korea would maintain and ensure the reliability of NPPs as well as public

    Asthma is a heterogeneous airway disease with various clinical phenotypes. It is crucial to clearly identify clinical phenotypes to achieve better asthma management. We used cluster analysis to classify the clinical groups of 724 asthmatic patients from the Cohort for Reality and Evolution of Adult Asthma in Korea (COREA), and in 1843 subjects from another independent Korean asthma cohort of Soonchunhyang University Asthma Genome Research Centre (SCH) (Bucheon, Republic of Korea). Hierarchical cluster analysis was performed by Ward's method, followed by κ-means cluster analysis. Cluster analysis of the COREA cohort indicated four asthma subtypes: 1) smoking asthma; 2) severe obstructive asthma; 3) early-onset atopic asthma; and 4) late-onset mild asthma. An independent cluster analysis of the SCH cohort also indicated four clusters that were similar to the COREA clusters. Our results indicate that adult Korean asthma patients can be classified into four distinct clusters. PMID:23060627

    2015-01-01

    Objectives: Among the Korean elderly (those 65 years of age and older), the suicide rate is 80.3/100 000 people, which is ten times higher than the Organization for Economic Cooperation and Development average. Because South Korea is rapidly becoming an aging population, this high elderly suicidal rate will only get worse. Although the size of the elderly suicide problem is quite large, previous research in South Korea has surveyed restricted areas and not the entire country. Even though the ...

    In the early 2000s, the prevalence of diabetes in adults aged ≥30 years in Korea was about 9% to 10%, and it remained stable. However, a nationwide survey showed that this prevalence increased over the past few years. After age-standardization using the Korean population of the year 2010, the prevalence of diabetes in adults aged ≥30 years was 10.0% to 10.8% between 2001 and 2012, which increased to 12.5% in 2013 and 11.6% in 2014. During that period, there have been changes in the gender- and age-specific prevalence of diabetes in Korean adults. The prevalence of diabetes in the elderly population increased significantly, while this prevalence in young adults, especially in young women, did not change significantly. The contribution of each diabetic risk factor, such as obesity, β-cell dysfunction, sarcopenia, and socioeconomic status, in developing diabetes has also changed during that period in each gender and age group. For young women, obesity was the most important risk factor; by contrast, for elderly diabetic patients, sarcopenia was more important than obesity as a risk factor. Considering the economic burden of diabetes and its associated comorbidities, a public health policy targeting the major risk factors in each population might be more effective in preventing diabetes.

  10. HDRK-Woman: whole-body voxel model based on high-resolution color slice images of Korean adult female cadaver

    International Nuclear Information System (INIS)

    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. (paper)

    2016-01-01

    Physical inactivity is a major risk factor for chronic diseases and premature death. The increased health risks associated with physical inactivity may also generate a heavier economic burden to society. We estimated the direct medical costs attributable to physical inactivity among adults using data from the 2002-2010 Korean National Health Insurance Service-National Sample Cohort. A total of 68,556 adults whose reported physical activity status did not change during the study period was included for this study. Propensity scores for inactive adults were used to match 23,645 inactive groups with 23,645 active groups who had similar propensity scores. We compared medical expenditures between the two groups using generalized linear models with a gamma distribution and a log link. Direct medical costs were based on the reimbursement records of all medical facilities from 2005 to 2010. The average total medical costs for inactive individuals were $1110.5, which was estimated to be 11.7% higher than the costs for physically active individuals. With respect to specific diseases, the medical costs of inactive people were significantly higher than those of active people, accounting for approximately 8.7% to 25.3% of the excess burden. Physical inactivity is associated with considerable medical care expenditures per capita among Korean adults. PMID:26797622

    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.

    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.

    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. PMID:26337763

  16. Development of the two Korean adult tomographic computational phantoms for organ dosimetry

    International Nuclear Information System (INIS)

    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 mm3 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 stylized

    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.

    International Nuclear Information System (INIS)

    The breast is a dynamic organ responding to hormone, age, and other factors. As an aging process, fibroglandular tissue of the breast parenchyma shows progressive fatty replacement. To evaluate the normal aging process, we reviewed ultrasonomammograms of 220 persons who had normal breast with contralateral benign disease retrospectively. Twenty persons in second decade and 40 persons for each decade from third to seventh we restudied. Skin thickness, ductal prominence, and echoes of mammary layer did not changed to age. Fatty change of mammary layer became prominent after fourth decade and then revealed more than 70% after sixth decade. Thickness of mammary layer decreased after second decade. The posterior portion of Cooper's ligament arising fromprepectoral fascia began to appear after fourth decade and was prominent after sixth decade. In conclusion, involutional change of the breast begins in premenopausal period

    Full Text Available BackgroundThe role of glycated hemoglobin (HbA1c in the prediction of ischemic stroke in non-diabetic subjects is not clear. We performed a study to analyze the role of HbA1c in the risk prediction of ischemic stroke in non-diabetic Korean males adult.MethodsA total of 307 non-diabetic male patients with ischemic stroke were enrolled, and 253 age-matched control subjects without a history of diabetes, hypertension, or cardiovascular disease were selected from a Health Check-up database. Anthropometric measurement data, fasting glucose level, lipid profile, and HbA1c level were available for all subjects. Associations of the variables and the presence or absence of ischemic stroke were analyzed.ResultsThe ischemic stroke patient group had significantly higher HbA1c levels (5.8±0.5% vs. 5.5±0.5%, P<0.01 and mean systolic and diastolic blood pressure compared with the control group. Among the variables, smoking, low high density lipoprotein cholesterol, systolic blood pressure, and HbA1c were the significant determinants for ischemic stroke. The highest quartile of HbA1c showed a 9.6-fold increased odds ratio for ischemic stroke compared with the lowest quartile of HbA1c (odds ratio, 9.596; 95% confidence interval, 3.859 to 23.863, P<0.01. The proportion of ischemic stroke patients showed a significant trend for increment as the deciles of HbA1c increased (P for trend <0.01.ConclusionHigher HbA1c indicated a significantly increased risk for ischemic stroke after adjusting for other confounding variables in non-diabetic Korean adult males. HbA1c might have significance in predicting the risk for ischemic stroke even in the non-diabetic range.

  6. Radiologic study on normal renocortical index of the Korean adults

    International Nuclear Information System (INIS)

    The renocortical index(RCI) is a number expressing the fraction of the area of the whole kidney which is occupied by the cavitary system and it is calculated by dividing the product renal length times width by the product length times breath of the cavitary system. Normal intravenous pyelograms of 232 cases taken at Chungnam National University Hospital for recent two years were analized. The following results were obtained. 1. The size of kidney in male is larger than in female and the right kidney is smaller than the left. 2. The ratio of renal length to the height of second lumbar vertebra in female is slightly higher than in male. 3. The mean RCI of the right kidney is 0.346 ± 0.035, the left kidney is 0.351 ± 0.038. 4. There is no significant difference between the RCI of right an left, and in 57% of the cases both kidneys show the RCI of same value. 5.

    Although an association between serum ferritin and atherosclerosis has been suggested, limited epidemiologic data are available regarding the association between ferritin and arterial stiffness in healthy adults. A total of 2932 healthy subjects were enrolled in this study. Anthropometric and biochemical profiles including ferritin were measured. The arterial stiffness was measured using brachial-ankle pulse wave velocity (baPWV). Serum ferritin levels were classified into quartiles and baPWV values gradually increased with each ferritin quartile. Multiple regression analysis showed that ferritin levels were independently correlated with baPWV. After adjusting for multiple risk factors, as compared with the lowest quartile, the odds ratios for high baPWV (>75(th) percentile) were 1.15 (0.84-1.56), 1.37 (0.97-1.73), and 1.46 (1.29-2.17) among men (p for trend Korean adults.

    Full Text Available Preservation of adult stem cells pools is critical for maintaining tissue homeostasis into old age. Exhaustion of adult stem cell pools as a result of deranged metabolic signaling, premature senescence as a response to oncogenic insults to the somatic genome, and other causes contribute to tissue degeneration with age. Both progeria, an extreme example of early-onset aging, and heritable longevity have provided avenues to study regulation of the aging program and its impact on adult stem cell compartments. In this review, we discuss recent findings concerning the effects of aging on stem cells, contributions of stem cells to age-related pathologies, examples of signaling pathways at work in these processes, and lessons about cellular aging gleaned from the development and refinement of cellular reprogramming technologies. We highlight emerging therapeutic approaches to manipulation of key signaling pathways corrupting or exhausting adult stem cells, as well as other approaches targeted at maintaining robust stem cell pools to extend not only lifespan but healthspan.

    Arsenic (As) is a major environmental pollutant and a known human carcinogen that is widely distributed in the air, soil, and water. General population is mainly exposed to As through drinking water and food from the contaminated water and soil. Arsenic in drinking water is generally well controlled now. This study was performed to estimate total and inorganic As intake and to determine the major contributing source in the Korean adult diet. The study subjects were 2117 healthy adults (922 males and 1195 females) who had not been occupationally exposed to As. Total dietary intake was studied using the 24-h recall method, which included 138 specific food items. The estimates of total As and inorganic As intake were based on total and inorganic As contents in each food item consumed during the last 24 h. Daily dietary intake was estimated to be 1373.6 g. Total As intake was estimated to be 145.4 µg As/day. Total dietary As intake was correlated with consumption of fish/shellfish, seaweeds, and grains. Approximately 87 % of total dietary As intake was attributed to seafood, such as 105.5 µg As/day from fish/shellfish and 20.5 µg As/day from seaweeds. Inorganic As intake was estimated to be 10.4 µg As per day. Inorganic As intake was mainly provided by grains (6.4 µg As/day), followed by seaweeds and fish/shellfish. Our results indicate that seafood and grains are the main As dietary sources in Korean adults and that dietary As exposure may be associated with individual dietary habits and environmental As contamination among countries.

    This study examined the use of preventive health services among Korean American adults. Data were drawn from a cross-sectional survey of 212 Korean Americans in the Chicago, Illinois, metropolitan area. Guided by the Andersen's behavioral model, the authors examined whether predisposing (age, gender, marital status, household size, education), enabling (income, health insurance, English proficiency, citizenship, social network), and need (health status) factors are predictive of Korean Americans' preventive health services utilization. A binomial logistic regression showed that younger age, male, noncitizen, low income, no insurance, a larger family network, and better perceived health were associated with decreased odds of using preventive health services.

    To determine the prevalence and degree of CAC (coronary artery calcification) in appearently healthy middle-aged Koreans, and the relation of CAC to risk factors for atherosclerosis. A total of 289 apparently healthy personnel at Yonsei University (male: 170, female:119, age: mean(SD=54.9{+-}7.1 years)) underwent EBT (electron bean tomography). The risk factors for athero-sclerosis, which included diabetes mellitus, hypertension, smoking, a family history of precocious onset, obesity, hyperlipidemia, and high intraperitoneal fat, were scrutinized. One hundred and sixty-eight subjects (58%) had at least one risk factor. The CAC score was calculated for all subjects and for each coronary artery separately and was then analyzed by age and sex and in relation to the risk factors. The prevalence of CAC was 40% in men and 18.5% in women (mean score:29.7 vs. 9.9). The number of individuals who had one, two, or more than two risk factors was 141,41, and 19, respectively. The number of risk factors and the prevalence and score of CAC were significantly correlated (p=0.01, 0.02 respectively). The number of individuals with no risk factor, with without CAC, was 58(20.1%) and 103(35.6%), respectively, while the number with some risk factor, with or without CAC, was 38(13.1%) and 90(31.1%), respectively. The CAC score was significantly higher in the presence of hypertension, low HDL, or obesity(p=0.001, 0.049, and 0.068, respectively). Smoking appeared to have a borderline effect on the calcium score(p=0.118). This study should provide useful information for interpreting CAC scores and establishing a treatment strategy for Koreans. The comparison of our results with other studies will enable a better understanding of the process and risk factors of atherosclerosis in Koreans.

  19. Paired-organ and other selected absorbed fraction for the Korean Reference Adult Male model

    International Nuclear Information System (INIS)

    The authors have developed a mathematical model for calculating internal radionuclide dosimetry for the Korean Reference Adult Male, and have also derived paired-organ and other selected inter-organ photon-specific absorbed fractions for this model. Each lung, kidney and adrenal gland was set as a separate source region even though each of them shares an identical physiological function with their complementary half. The thyroid gland was also set as a source region. Specific absorbed fractions (SAFs) were then derived by selecting 10 photon energies from 0.02 to 4.0 MeV inclusive. For this purpose the Monte Carlo methodology was used, and the derived SAF was compared with the resulting value of MIRD Pamphlet No. 5 and ORNL TM-8381, both of which were derived on the basis of the ICRP-23 reference man. The comparison showed that MIRD No. 5 and ORNL TM-8381 resulted in a higher absorbed fraction, but the phantom created on the basis of the Korean reference man led to a higher SAF. The weight of the organs of the phantom, and the size and location of the trunk seem to account for the differences. The energy-dependent differences in the SAFs are considered to be related to the distance between the source and target regions, the composition of the intervening tissues, and the photon energies and mean free paths. Also, as a result of deriving SAFs after setting each separate lung, kidney and adrenal gland as a source region, it was found that, although they are of the same physiological function, each individual organ serves as a source region on its own. Differences were noted in SAFs exerted on the source and target organs in accordance with the location of the organs, that is, whether they were located to the left or right of the source organs. The SAF derived in this study can be used for a more accurate internal radionuclide dosimetry for Koreans and other Orientals whose physiology, lifestyle and dietary habits are similar to those of Koreans.

    2016-01-01

    PURPOSE The purpose of this study was to determine the effect of changes in the horizontal plane angle on the mesiodistal width ratios of the maxillary anterior teeth during the acquisition of frontal view photographs, derive these ratios for Korean adults on the basis of the data obtained, and analyze them using the Golden Proportion as a reference. MATERIALS AND METHODS In experiment I, 30 plaster casts were mounted on an articulator and positioned on the angle-measuring device with a center setting of 0°. The device was rotated to 10° in 1° increments in a counterclockwise direction. At each angle, photographs were obtained and analyzed. Experiment II was based on 60 patients who visited the Department of Prosthodontics at Kyungpook National University Dental Hospital from February 2012 to February 2015. The patients were divided into three groups [Male (M), Female (F), Total (M + F)]. Frontal views were obtained for all groups and analyzed. RESULTS From 1° to 10°, the relative mesiodistal width ratios for the maxillary anterior teeth showed no significant differences from those at 0°. In all three groups, the relative width ratio of the maxillary central incisor was smaller than that specified in the Golden Proportion; the opposite was true for the canine. CONCLUSION Our results suggest that the mesiodistal width ratios of the maxillary anterior teeth do not follow the Golden Proportion in Korean adults, and that a change in the horizontal plane angle from 1° to 10° during frontal photography does not affect these ratios.

    Background Metabolic syndrome (MS) is known to increase the risk of various cardiometabolic diseases and in-sulin resistance (IR) has known to have central role in the development of MS. Many surrogate indices of IR have been proposed and the detection of MS might be a suitable model for assessing the accuracy of surrogate indices. The aims of our study are to invest the most appropriate index by assessment of the diagnostic capacity of IR among each surrogate index and identifying cut-off values for discriminating uncomplicated MS in Korean adults. Methods A cross-sectional study was performed, assessing 294 Korean adults, 85 of whom were diagnosed with uncomplicated MS. The sensitivities and specificities of five surrogate IR indices were compared to discriminate MS from healthy subjects; these included fasting serum insulin, homeostasis model assessment–insulin resistance index, quantitative insulin sensitivity check index, McAuley index, and Disse index. Correlations between each index value were assessed using Pearson's and Spearman's correlation methods. Results The McAuley index showed the highest area under the curve (0.85), specificity (86.12%), accuracy (82.31%), positive predictive value (68.13%), and negative predictive value (88.67%) to distinguish MS, with a cut-off point of 5.3 defined. Correlation coefficients of the five indices showed that the McAuley index had the strongest correlation with IR. Conclusion The McAuley index showed the best accuracy in the detection of MS as a surrogate marker of IR. To establish more effective and accurate standards of measuring IR, comprehensive and multi-scaled studies are required.

    The prevalence of atopic dermatitis (AD) has continuously increased throughout the world in every age group, and the recent increase in AD in Korean adults may be related to changes in nutrient intakes due to westernization of dietary patterns. We hypothesized that the prevalence of AD is associated with the different dietary patterns and fermented food intakes of the Korean adult population. We examined the hypothesis using 9763 adults 19 years or older using the 2012-2013 Korean National Health and Nutrition Examination Survey. We identified 4 dietary patterns in addition to that including fermented foods using principal component analysis on data obtained from a 116-item validated semiquantitative food frequency questionnaire: meat and processed foods; vegetables, fruits, legumes, seafood, and seaweed; rice and grains; and coffee, chocolate, and ice cream. Adjusted odds ratios (ORs) for AD were calculated according to dietary patterns after adjusting for potential confounders. High levels of consumption (>92 times/month) of fermented foods such as doenjang, chungkookjang, kimchi, fermented seafood, makgeolli, and beer were associated with a lower prevalence of AD (OR, 0.56; 95% confidence interval [CI], 0.37-0.84). In contrast, high levels of consumption of meat and processed foods were strongly associated with the prevalence of AD (OR, 2.42; 95% CI, 1.48-3.94). Interestingly, the consumption of coffee, chocolate, and ice cream was significantly negatively associated with the prevalence of AD (OR, 0.53; 95% CI, 0.34-0.82). In conclusion, the hypothesis was accepted. The results can be applied to nutrition education programs for the general population to decrease risk factors for AD. PMID:26826428

    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.

    Background Osteoporosis one of the most serious disease to decrease the quality of life and cause economic loss. Thus, prevention of osteoporosis has become an important health concern. The study examined in adherence to osteoporosis guidelines and compared the levels of adherence to osteoporosis guidelines between bone health status in Korean adult. Methods This study used data from a nationally represented sample of Koreans (n=3,419) from 2008 to 2011 Korea National Health and Nutrition Examination Survey. We were divided into three groups by T-score: normal, osteopenia and osteoporosis. Assessment of adherence level was based on 5 components of osteoporosis guidelines, considering intake of sodium, calcium and protein, smoking and regular exercise. Results The sex, body mass index, income and educational level did not significantly differ between three groups. Deficient intake of calcium was significantly associated with a threefold greater odds in osteoporosis group (OR 3.6; 95% confidence interval [CI] 2.52-5.22). Excessive protein intake was significantly increased the risk only in osteoporosis group compared to the normal group (OR 1.71; 95% CI 1.15-2.62). Smoking increased the risk in osteoporosis group compared to the normal group (OR 2.88; 95% CI 1.75-4.76), osteoporosis group compared to the osteopenia group (OR 2.69; 95% CI 1.61-4.55). Conclusions Nutritional factor (intake of calcium and protein) and lifestyle-related factor (smoking and exercise) must be accompanied the management for bone health. An adherence of guidelines is considered very important for the prevention of osteoporosis.

    This study investigates the cancer literacy level in Korean adults and examines whether cancer literacy plays a mediating role in the relationship between population characteristics and cancer screening behaviours. We collected data from 585 community-dwelling adults in Korea using self-administered surveys and face-to-face interviews from October to December in 2009. Guided by Andersen's behavioural model, we used a structural equation model to estimate the effect of cancer literacy as a mediator and found that cancer literacy mediated cancer screening behaviour. In the individual path analysis models, cancer literacy played a significant mediating role for the use of eastern medicine, fatalism, health status and the number of chronic diseases. When controlling for other relevant covariates, we found that in the optimal path model, cancer literacy played a mediating role in the relationship between the use of eastern medicine and self-rated health status as well as cancer screening behaviour. Thus, developing community-based cancer education programmes and training clinical practitioners in eastern medicine clinics about the importance of informing their patients about regular cancer screening may be an option to boost cancer literacy and screening behaviour in Korea.

  7. Diurnal Variations in Serum Glucose, Insulin and C-Peptide of Normal Korean Adults

    International Nuclear Information System (INIS)

    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

    This experiment tests the effect of an old-age progression simulation on young adults' (N = 139) reported aging anxiety and perceptions about older adults as a social group. College students were randomly assigned to one of three conditions: self-aged simulation, stranger-aged simulation, or a control group. Compared with the control group, groups exposed to an age progression experienced more negative affect, and individuals in the self-aged condition reported greater aging anxiety. In accordance with stereotype activation theorizing, the self-age simulation group also perceived older adults as less competent and expressed more pity and less envy for older adults. Compared to the stranger-aged group, participants who observed their own age progression were also the more likely to deny the authenticity of their transformed image.These findings highlight potential negative social and psychological consequences of using age simulations to affect positive health outcomes, and they shed light on how virtual experiences can affect stereotyping of older adults.

    To evaluate if HIV transmission networks could be elucidated from data collected in a short time frame, 131 HIV-1 pol sequences were analyzed which were generated from treatment-naïve Korean individuals who were sequentially identified over 1 year. A transmission linkage was inferred when there was a genetic distance <1.5% and a total of 16 clusters, involving 39/131 (29.8%), were identified. Younger age and heterosexual exposure were independently related with clustering in the inferred network, which demonstrated that molecular epidemiology with currently generated data (i.e., drug resistance genotypes) can be used to identify local transmission networks, even over a short timeframe.

    The authors have taken the x-ray films of carpal bone and orthopantomographs in Korean children to research the degree of ossification of carpal bone, that of calcification of tooth in jaw bone, the eruption rate of tooth, and the completion rate of apical foramen, and have compared the bone age with tooth age. We have gained a series of interesting conclusions to dare to report. 1. The ossification of carpal bone and the growth of tooth had processed proportionally to each other. 2. Both the bone age and tooth age were earlier in the female than in the male. 3. The completion of tooth crown formation and that of tooth root formation had processed proportionally to each other, and the general tendency of process was earliest in the mandibular first molar and the latest in the second molar. 4. The eruption of tooth was earliest in the mandibular first molar. The other teeth had erupted in the following order : the central incisor, the lateral incisor, the first premolar, the second premolar, the canine, and the second molar.

    2016-08-01

    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. PMID:25735753

In the suicidal process, suicidal ideation is a key stage in the pathway leading to eventual suicide. This study investigated the influence of physical activity and functional limitations on suicidal ideation among young and middle-aged adults in a high suicidal society. Data for the current study were obtained from the Fourth Korea National Health and Nutrition Examination Survey 2007-2009 (KNHANES), a cross-sectional study conducted by the Korea Centers for Disease Control and Prevention. The survey conducted face-to-face interviews with young adults (n = 2326) and middle-aged adults (n = 3396). Using multivariate logistic regression analysis, the relationship of physical activity and functional limitations with suicidal ideation in young and middle-aged adults was assessed. A notable outcome was that the absence of a regular walking was correlated with increased suicidal ideation in middle-aged women. The other major finding was that young women and middle-aged adults with functional limitations had a high rate of suicidal thoughts. Multiple intervention approaches, including informational, social and behavioural approaches, are needed to promote regular walking in middle-aged women. For instance, mass media campaigns, community walking groups and individually adapted health behaviour modification may provide opportunities for positive intervention. Additionally, another important public health implication from these findings is the need for a suicide-intervention support system that includes screening for suicide risk in healthcare settings, especially among young women with physical limitations.

  19. Application of instrumental neutron activation analysis to assess dietary intake of selenium in Korean adults from meat and eggs

    International Nuclear Information System (INIS)

    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)

    Full Text Available Abstract Background It is thought that small volumes of alcohol may have positive effects on health. However, excessive drinking results in serious health problems. An accurate method to determine individual alcohol use behaviors are needed to assess objectively the extent to which drinking affects health. This study investigated the association between risk of metabolic syndrome (MetS and alcohol use behaviors in middle-aged South Korean men using the Alcohol Use Disorders Identification Test. Methods This study used data from the South Korea National Health and Nutrition Examination (KNHANES IV (2008, which extracted the standard survey household by using the proportional systematic sampling method. Data of 714 participants from KNHANES IV, 2008 were analyzed using Surveyfreq and Surveylogistic regression to investigate the association between MetS and alcohol use behaviors in middle-aged South Korean men. Results After adjustment for education, smoking, and physical activity, alcohol use behaviors were significantly associated with an increased risk of hypertension [odds ratio (OR = 2.54, 95% confidence interval (CI = 1.5-4.06 in the hazardous group; OR = 2.99, 95% CI = 1.84-4.92 in the problem group]; impaired fasting glucose (OR = 2.15, 95% CI = 1.16-3.99 in the hazardous group; OR = 2.48, 95% CI = 1.42-4.33 in the problem group; dyslipidemia (OR = 2.19, 95% CI = 1.38-3.47 in the problem group; abdominal obesity (OR = 1.93, 95% CI = 1.17-3.19 in the hazardous group; OR = 1.85, 95% CI = 1.17-2.92 in the problem group; and MetS (OR = 2.16, 95% CI = 1.24-3.77 in the hazardous group; OR = 2.54, 95% CI = 1.41-4.58 in problem group. Conclusions This study found that excessive alcohol use behaviors increased the risk of hypertension, diabetes, dyslipidemia, abdominal obesity, and MetS. Considering the rising rate of alcohol consumption and heavy drinking at single sittings, a culture of less risky alcohol consumption must be established to promote

    Background 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. Methods 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. Results 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. Conclusion 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

    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

    Prolonged sedentary time and sleep deprivation are associated with mental health problems such as depression and stress symptoms. Moreover, mental illness is linked with suicidal thoughts and suicide attempts. However, it is not clear whether sedentary time and sleep duration are associated with stress symptoms and suicidal thoughts independent of physical activity. Thus, our study aimed to identify if sedentary time and sleep duration were associated with both stress symptoms and suicidal thoughts. The participants in present cross-sectional study were 4,674 general Korean adults (1,938 male; 2,736 female), aged ≥ 20 years. Prolonged sedentary time (≥ 420 min/day) was significantly associated with the increased risk of stress symptoms (OR, 1.30; 95% CI, 1.04-1.62) compared with sedentary time of sleep time (OR, 1.88; 95% CI, 1.48-2.38) compared with sleep duration of ≥ 7 h/day. Moreover, prolonged sedentary time (OR, 1.55; 95% CI, 1.01-2.42 in ≥ 420 min/day vs. sleep duration (OR, 1.75; 95% CI, 1.17-2.62 in ≤ 5 h/day vs. ≥ 7 h/day) were significantly associated with an increased risk for suicidal thoughts after adjusting for confounding factors including physical activity. Thus, prolonged sedentary time and sleep deprivation are independently associated with both the risk of stress symptoms and suicidal thoughts. From a public health perspective, reducing sedentary time and improvement of sleep deprivation may serve as an effective strategy for preventing mental illness. PMID:26596898

    Full Text Available OBJECTIVE: To investigate the association between serum 25-hydroxyvitamin D [25(OHD] levels and nonalcoholic fatty liver disease (NAFLD independent of visceral obesity in Koreans and to examine whether the associations differ according to the presence of diabetes or insulin resistance. RESEARCH DESIGN AND METHODS: A total of 1081 adults were enrolled from a population-based cohort in Ansan city. Serum 25(OHD concentrations were measured in all subjects. Insulin resistance was measured by homeostasis model assessment of insulin resistance (HOMA-IR. Using computed tomography, NAFLD was diagnosed if the liver attenuation index (LAI, the difference between the mean hepatic and splenic attenuation was <5 Hounsfield Units. RESULTS: In subjects with diabetes (n = 282, 25(OHD levels were negatively associated with waist circumference, fasting insulin, HOMA-IR, triglyceride levels, and visceral abdominal fat, and were positively associated with LAI after adjusting for age, sex, season, exercise, and vitamin supplementation. In subjects without diabetes, only triglyceride level was negatively associated with 25(OHD. The adjusted odds ratio (OR for NAFLD increased sequentially across decreasing quartiles of 25(OHD in subjects with diabetes even after adjusting for visceral fat [Q1 vs. Q4; OR for NAFLD 2.5 (95% CI:1.0-6.2]. In contrast, no significant difference in OR was observed in subjects without diabetes. When we classified non-diabetic subjects by HOMA-IR, an increase in the OR for NAFLD across decreasing quartiles of 25(OHD was observed in the high HOMA-IR (≥2.5 group [n = 207, Q1 vs. Q4; OR 3.8(1.4-10.3], but not in the low HOMA-IR (<2.5 group [n = 592, OR 0.8 (0.3-1.9]. CONCLUSIONS: Low vitamin D status is closely associated with NAFLD, independent of visceral obesity in subjects with diabetes or insulin resistance.

    This study was conducted to assess the relationship between body composition and suicidal ideation among the Korean elderly population (n = 302; ≥ 65 years) who participated in the Hallym Aging Study in 2010. Body composition was measured using dual-energy X-ray absorptiometry, and obesity was measured by the indices of body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), and body fat percentage. Sarcopenia was defined as presence of both low muscle mass and low muscle function. Suicidal ideation was assessed using the Beck Scale for Suicide Ideation. We found no differences in body composition measures between subjects with suicidal ideation and those without. In the logistic regression analyses, there were no significant relationships for suicidal ideation according to body composition measures, including BMI, WC, WHR, WHtR, and body fat percentage in both sexes. After adjusting for age, smoking status, alcohol drinking, regular exercise, medical comorbidities, monthly income, education level, and presence of depressive symptoms, the odds ratio (OR) of suicidal ideation was higher in elderly men with sarcopenia compared to those without, whereas no significant relationships were observed in elderly women (OR 8.28, 95% confidence interval [CI] 1.20-61.34 in men; OR 0.79, 95% CI 0.07-8.43 in women). Sarcopenia is closely associated with an increased risk of suicidal ideation in elderly men. PMID:27051246

    International Nuclear Information System (INIS)

    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 FEV1/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 FEV1/FVC ratio (β=−0.017, p=0.001, adjusted R2=0.267). The odds ratios (ORs) for the FEV1/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 FEV1/FVC ratio. • Blood lead level was a significant influencing factor for the FEV1/FVC ratio. • ORs for FEV1/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

    The aim of this study was to investigate the influence of types of message errors on the attitudes of Korean adults toward a person who uses AAC. The attitudes of 72 adults who speak native Korean were examined through attitude questionnaires completed after viewing videotaped conversations between a boy with cerebral palsy and an adult without disabilities. Each interaction video involved a message with one of six error types, including various types of syntactic, semantic, and pragmatic errors. The participants provided information on their attitude towards the person who used AAC, and ranked their preferences among the six messages. The results provide evidence that attitudes towards the individual using AAC were most positive (in comparison with other conditions) when a pragmatic error was observed. Messages containing a syntactic error were ranked most favorably. Spearman's correlation analyses revealed some relationship between attitudes rating and preferences ranking. Our results provide evidence that specific language and cultural contexts may play an important role in shaping attitudes toward those who use AAC. PMID:25716683

    Full Text Available Abstract Background Studies have identified that environmental tobacco smoke exposure is associated with sociodemographic factors such as age, sex, and socioeconomic status, but few studies have been conducted in South Korea. In this study, the authors investigated the extent of environmental tobacco smoke exposure and factors related in a nationally representative sample of Korean adults. Methods The data of 7,801 adults aged 19 years and over collected during the 2005 Korea National Health and Nutrition Examination Survey were analyzed. Information on smoking habits and exposure to environmental tobacco smoke was obtained by self-reports using a standardized questionnaire. Risks of environmental tobacco smoke exposure conferred by sociodemographic variables and behavioral risk factors were evaluated using logistic regression methods. Results Overall, 36.1% of nonsmokers (defined as those not currently smoking and 50.1% of current smokers were found to be exposed to environmental tobacco smoke either at work or at home. Among the nonsmokers, women were more likely to be exposed to environmental tobacco smoke at home (OR = 5.22, 95%CI, 4.08-6.67. Furthermore, an inverse relationship was found between education level and the risk of environmental tobacco smoke exposure at home (OR = 1.73, 95%CI, 1.38-2.17 for those with a high school education; OR = 2.30, 95%CI, 1.68-3.16 for those with a middle school education; and OR = 2.58, 95%CI, 1.85-3.59 for those with less than an elementary school education vs. those with a college education or more. In addition, those with office, sales service, or manual labor jobs were found to be at significantly higher risk of environmental tobacco smoke exposure at work than those with professional, administrative, or managerial jobs. Also, the risk of environmental tobacco smoke exposure in the workplace was significantly higher for alcohol drinkers than non-drinkers (OR = 1.23, 95%CI, 1.07-1.47. After adjusting

    Purpose We investigated the association between seasonal influenza vaccination in South Korea and socioeconomic status (SES) as well as other potential related factors. Methods The study was based on data obtained in the Korea National Health and Nutrition Examination Survey from 2010 to 2011. Education level and household income were used as indicators for SES. Univariate and multiple logistic regression analyses were used to evaluate SES and other demographic variables as related factors for influenza vaccination, the primary outcome. Results Higher household income was positively associated with higher vaccine uptake in the younger (19–49 years) group [adjusted odds ratio (aOR) 1.55, 95% confidence interval (CI) 1.08–2.23], whereas the low-income and low-education group had increased vaccination coverage than the middle-income and middle-education group in the older (≥ 50 years) group (aOR 1.36, 95% CI 1.09–1.69). Current smokers tend to be unvaccinated in all age groups. Among individuals aged ≥ 50, older age, mild to moderate alcohol consumption, regular exercise, and having co-morbidities were positively associated with vaccination, while those who self-reported their health status as good were less likely to be vaccinated. Conclusions The relationship between SES and seasonal influenza vaccination coverage differed between the age groups throughout the adult South Korean population. Public health policies need to address these inequalities. PMID:25646847

    Offending food allergens can vary with regional preferences in food consumption. 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.

    Background Research suggests that mental health is affected not only by smoking, but also by secondhand smoking. But the most researches have been conducted in North America and/or Europe. We examined whether this relationship remains evident within the South Korean population. Specifically, we investigated the effect of secondhand smoking on depressive symptoms and suicidal ideation. Methods We analyzed data from 6,043 non-smoking adults who participated in the 2010–2012 Korea National Health and Nutrition Examination Survey. We compared the presence of depressive symptoms and suicidal ideation in 3,006 participants who were exposed to secondhand smoking in the office or at home with 3,037 non-exposed participants. Results In unadjusted logistic regression analysis, secondhand smoking exposure group had more suicidal ideations than no secondhand smoking exposure (16.1% vs. 12.2%; odds ratio [OR], 1.50; 95% confidence interval [CI], 1.241–1.804), but risk of depressive symptoms was not significantly different between two groups (15.2% vs. 12.2%; OR, 1.21; 95% CI, 0.997–1.460). In multivariate logistic regression analysis, Among those exposed to secondhand smoking, the OR for depressive symptoms was 1.02 (95% CI, 0.866–1.299) and 1.43 (95% CI, 1.139–1.802) for suicidal ideation. Overall, secondhand smoking at home was significantly related to depressive symptoms and suicidal ideation. Among females, secondhand smoking exposure at home only (not in the office) was related to depressive symptoms and suicidal ideation. Conclusion Exposure to secondhand smoking, especially at home, may be associated with an increase in especially in female depressive symptoms and suicidal ideation among adults in South Korea.

  3. Application of instrumental neutron activation analysis to assess dietary intake of selenium in Korean adults from meat and eggs

    International Nuclear Information System (INIS)

    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)

    The present article aimed to provide a comprehensive review of current status of end-of-life (EOL) care and sociocultural considerations in Korea, with focus on the EOL communication and use of advance directives (AD) in elderly Koreans. Through literature review, we discuss the current status of EOL care and sociocultural considerations in Korea, and provide a look-ahead. In Korea, patients often receive life-sustaining treatment until the very end of life. Advance care planning is rare, and most do-not-resuscitate decisions are made between the family and physician at the very end of patient's life. Koreans, influenced mainly by Confucian tradition, prefer a natural death and discontinuation of life-sustaining treatment. Although Koreans generally believe that death is natural and unavoidable, they tend not to think about or discuss death, and regard preparation for death as unnecessary. As a result, AD are completed by just 4.7% of the general adult population. This situation can be explained by several sociocultural characteristics including opting for natural death, wish not to burden others, preference for family involvement and trust in doctor, avoidance of talking about death, and filial piety. Patients often receive life-sustaining treatment until the very EOL, advance care planning and the use of AD is not common in Korea. This was related to unique sociocultural characteristics of Korea. A more active role of physicians, development of a more deliberate EOL discussion process, development of culturally appropriate AD and promotion of advance care planning might be required to provide good EOL care in Korea.

    Full Text Available Abstract Background Elevated blood pressure (BP is a major risk factor for the progression of chronic kidney disease (CKD. However, little is known about the influence of prehypertension on CKD. In this study, we investigated the relationship between prehypertension and CKD in a middle-aged Korean population. Furthermore, we prospectively evaluated the effect of active BP control on deterioration of kidney function during the two-year follow-up. Methods The Korean Genome and Epidemiology Study is a community-based prospective cohort study started in 2001, with a follow-up survey conducted every two years. A total of 9509 participants aged 40–69 years were included in a baseline study. BP was classified according to the Seventh Report of the Joint National Committee on High BP (JNC-7 categories and CKD was defined as the presence of proteinuria or eGFR2. A multivariable logistic regression model was used to identify associations between BP and CKD. Results The overall prevalence of CKD was 13.2%, and significantly increased with BP level. The multivariable-adjusted odds ratio of CKD was 1.59 for prehypertension and 2.27 for hypertension, compared with a normal BP. At the two-year follow-up, among the participants with prehypertension, subjects whose BP was poorly controlled had a significantly higher risk of eGFR drop (OR, 1.37; 95% CI, 1.13-1.67, as compared to controls. The prevalence of eGFR drop was 57.8% in the controlled BP group and 66.0% in the poorly-controlled BP group. Conclusions Prehypertension, as well as hypertension, is significantly associated with CKD among middle-aged Koreans. Our results indicate that active control of the blood-pressure of prehypertensive individuals is needed to prevent deterioration of kidney function.

    Human exposure to Bisphenol A (BPA) and phthalates is a growing concern due to their association with harmful effects on human health, including a variety of disorders of the female reproductive system. The objective of this study was to investigate the association between food intake and urinary BPA and phthalates in Korean women of reproductive age. A cross-sectional study was conducted with 305 reproductive aged (30–49 years) females in Korea. Dietary intake was assessed using 24 h dietary recall, and urinary BPA and particular phthalates were measured using high performance liquid chromatography tandem mass spectrometry. After adjusting for covariates, beverage intake was positively associated with urinary BPA, and egg and egg product intake was negatively associated with urinary mono-n-butyl phthalate (MnBP) as well as mono (2-ethyl-5-oxohexyl) phthalate (MEOHP). Odds ratio for high BPA level (≥90th percentile) in women with >100 g of beverage consumption was significantly higher than for those who consumed ≤100 g. These results suggest that, in Korean women of reproductive age, some foods such as beverages and egg may be associated with body burdens of BPA, MnBP, MEHHP and MEOHP. PMID:27399734

    Full Text Available Background. Abdominal obesity and its relative distribution are known to differ in association with metabolic characteristics and cardiorespiratory fitness. This study aimed to determine an association between fitness level and abdominal adiposity in overweight and obese adults. Methods. 228 overweight and obese individuals were classified as either cardiorespiratory unfit or fit based on their recovery heart rate. Visceral adipose tissue (VAT, subcutaneous adipose tissue (SAT, the visceral-to-subcutaneous adipose tissue ratio (VAT/SAT ratio, and cardiometabolic characteristics were analyzed to examine the relationship between recovery heart rate and abdominal adiposity components. Results. After adjustments for age and sex, significant relationships of recovery heart rate and VAT, SAT, and VAT/SAT ratio were found; however, SAT was not significantly associated after further adjustment for body mass index (BMI (r=0.045, P=0.499, whereas VAT (r=0.232, P<0.001 and VAT/SAT ratio (r=0.214, P=0.001 remained associated. Through stepwise multiple regression analyses after adjustment for age, sex, BMI, lifestyle factors, mean blood pressure, fasting glucose, HOMA-IR, lipid profiles, and hsCRP, recovery heart rate was identified as an independent variable associated with VAT (β=0.204, P<0.001 and VAT/SAT ratio (β=0.163, P=0.008 but not with SAT (β=0.097, P=0.111. Conclusions. Cardiorespiratory fitness level is independently associated with VAT and the VAT/SAT ratio but not with SAT in overweight and obese adults.

    There has been a great improvement in height and weight of Korean children owing to economic development over the last 25 years. This study aimed to evaluate the penile length of Korean children today and to compare it with a previous Korean study reported in 1987. The cross-sectional study was conducted with 909 Korean boys aged 0-14 years who had been brought to outpatient clinics of five tertiary hospitals (Busan, Ulsan, and Changwon) between September 2013 and May 2015. The stretched penile length (SPL) was measured and the testicular size was measured using orchidometry (mL). Student's t-test or Mann-Whitney U test was used to compare the result of our study and the study reported in 1987. SPL of Korean children gradually increased from 4.1 ± 0.8 cm at 0-1 year old to 9.6 ± 3.0 cm at 13-14 years old, the most rapidly during the age of 13. While body weight and testicular size significantly increased from 1987 in most of age groups, there were no significant changes in SPL although there was in some age groups. Height decreased in the infants 6 years old. With the great economic development over the last quarter century in Korea, height, body weight, and testicular size of children significantly increased but there was no significant change in SPL except penile growth pattern.

    Full Text Available Low-level mercury (Hg exposure in infancy might be harmful to the physical growth as well as neurodevelopment of children. The aim of this study was to investigate postnatal Hg exposure and its relationship with anthropometry and dietary factors in late infancy. We recruited 252 healthy Korean infants between six and 24 months of age from an outpatient clinic during the 2009/2010 and 2013/2014 seasons. We measured the weight and height of the infants and collected dietary information using questionnaires. The Hg content of the hair and blood was assessed using inductively coupled plasma mass spectroscopy. The geometric mean Hg concentration in the hair and blood was 0.22 (95% confidence interval: 0.20–0.24 µg/g and 0.94 (n = 109, 95% confidence interval: 0.89–0.99 µg/L, respectively. The hair Hg concentration showed a good correlation with the blood Hg concentration (median hair-to-blood Hg ratio: 202.7, r = 0.462, p < 0.001 and was >1 µg/g in five infants. The hair Hg concentration showed significant correlations with weight gain after birth (Z-score of the weight for age—Z-score of the birthweight; r = −0.156, p = 0.015, the duration (months of breastfeeding as the dominant method of feeding (r = 0.274, p < 0.001, and the duration of fish intake more than once per week (r = 0.138, p = 0.033.

  15. Normal reference values for vertebral artery flow volume by color Doppler sonography in Korean adults

    International Nuclear Information System (INIS)

    Vertebrobasilar ischemia has been attributed to a reduction of net vertebral artery flow volume. This study was to establish the reference values for the flow volume of the vertebral artery using color Doppler sonography in the normal Korea adults. Thirty five normal Korea adults without any underlying disease including hypertension, hyperlipidemia, diabetes, heart disease, obesity (body mas index>30), or carotid artery stenosis was included. There were 17 males and 18 females, age ranged from 20 to 53 years (average=32.86 years). Flow velocities and vessel diameters were recorded in the intertransverse (V2) segment, usually at C5-6 level, bilaterally. The flow volume (Q) was calculated. (Q=time averaged mean velocity x cross sectional area of vessel) A lower Flow velocity and smaller vessel diameter were measured on the right side compared to those of the left side, resulting in a lower flow volume. The calculated flow volumes using the equation were 77.0 ± 39.7 ml/min for the right side and 127.6 ± 71.0 ml/min for the left side (p=0.0001) while the net vertebral artery flow volume was 204.6 ± 81.8 ml/min. Decrease in the vertebral artery flow volume was statistically significant with advanced age. (r=-0.36, p=0.032). Vertebral artery blood flow volume was 191.20 ± 59.19 ml/min in male, and 217.28 ± 98.67 ml/min in female (p=0.6). The normal range for the net vertebral artery flow volume defined by the 5th to 95th percentiles was between 110.06 and 364.1 ml/min. The normal range for the net vertebral artery flow volume was between 110.06 and 364.1 ml/min. Vertebral artery flow volume decreased with the increase of age. However, gender did not affect the blood flow volume.

    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. PMID:26211934

  17. Transabdominal ultrasonographic measurement of prostatic size and weight in the normal Korean adults

    International Nuclear Information System (INIS)

    Authors analyzed 154 cases of transabdominal ultrasonography of normal adults who had normal urinalysis, no complaint of symptoms related with urinary system and no evidence of prostate disease. The maximum anteroposterior, transverse and longitudinal diameters of prostate were measured. The weight of prostate was computed using the formula for the weight of ellipsoid object (W = SG X 4/3π X r1·r2·r3, w; weight, SG; specific gravity about 1.05 gm/ml, r; radius of prostate in any dimension). The results were as follows; 1. The average sized of prostate were 4.12 ± 0.68 cm in transverse diameter, 3.46 ± 0.49 cm in longitudinal diameter and 2.36 ± 0.40 cm in AP diameter. Transverse diameter was the longest and AP diameter was the shortest in all cases. 2. The average weight of posterior in each age groups were 19.25 ± 6.78 gm in the 3rd decade, 16.64 ± 5.18 gm in the 4th decade, 16.28 ± 5.31 gm in the 5th decade, 22.31 ± 6.95 gm in the 6th decade and 23.06 ± 8.18 gm in over the 7th decade. The average weight of prostate in groups more than 50 years of age were significantly greater than younger age groups (p< 0.005). Total average weight was 18.96 ± 6.78 gm. 3. The distribution of prostate weight over 30 gm in each groups were 14.29% (5/35) in the 3rd decade, 0% (0/34) in the 4th decade, 2.63% (1/38) in the 5th decade, 20% (6/30) in the 6th decade and 23.5%(4/17) in the 7th decade.

    Full Text Available Abstract Background Effective stroke intervention and risk reduction depend on the general public's awareness and knowledge of stroke. In Korea, where both traditional Oriental medicine and Western medicine are practiced, estimates of the general public's awareness and knowledge of stroke are poor. The present study sought to describe the inception cohort of the Ansan Geriatric Study (AGE study and to determine baseline stroke awareness and preferred medical treatment for stroke in this Korean sample. Methods A total of 2,767 subjects selected randomly from the Ansan Geriatric Study in South Korea were questioned about stroke. Their answers were compared with their sociodemographic data and other variables. Results Only 44.8% of participants correctly identified stroke as a vascular disease in the human brain. Sudden numbness or weakness was the most frequently identified stroke warning sign (60.2%. Hypertension (66.7% and mental stress (62.2% were most frequently identified as stroke risk factors. The contributions of diabetes mellitus and cardiovascular disease to stroke were underestimated; they were identified as risk factors by 28.3% and 18.6% of participants, respectively. The predictors for poor knowledge of stroke warning signs and risk factors were similar irrespective of preference for Western or Oriental medical treatment, and included those with lower levels of education and inaccurate definition of stroke. Television and radio (40.3% were the most frequent sources of stroke information for both groups. Conclusion This study shows that knowledge of stroke is similar among Koreans with preferences for either Western or Oriental medical treatment and that misunderstandings about stroke are common among the Korean elderly. In order to prevent and manage stroke effectively, public health education regarding basic concepts of stroke is necessary. This should target those with a lower level of education and a misunderstanding of the

  20. Optimal waist circumference cutoff values for the diagnosis of abdominal obesity in korean adults.

    Abdominal obesity is associated closely with insulin resistance, diabetes, and cardiovascular disease. Waist circumference (WC) is a useful surrogate marker commonly used for abdominal adiposity. The determination of WC cutoff levels is important in the prevention and treatment of obesity, type 2 diabetes, and related cardiovascular diseases. Recent epidemiological evidence suggested that appropriate optimal cutoffs for Koreans ranged over 80 to 89.8 cm in males and 76.1 to 86.5 cm in females. We analyzed the data from two large cohorts using receiver operating characteristic curve analysis with the incidences of diabetes, hypertension, dyslipidemia, cerebrovascular disease, myocardial infarct, angina, coronary artery disease, and multiple metabolic risk factors as outcome variables. Optimal WC cutoff points for Koreans were 85 cm in males and 80 cm in females. However, considering the prevalence of abdominal obesity and the health costs for its prevention and management, 90 cm in males and 85 cm in females are probably more appropriate thresholds for abdominal obesity. These values may be modified once better research is performed through prospective studies using representative populations, common health outcomes, and proper analytical approaches. PMID:25559570

    Background/Aims Waist circumference (WC) is a risk factor for metabolic syndrome and is related to insulin resistance (IR) and nonalcoholic fatty liver disease (NAFLD). The purpose of this study was to determine the association between WC and IR and NAFLD in apparently healthy Korean adults. Methods The volunteers included in this cross-sectional study comprised 9,159 adults (5,052 men, 4,107 women) who participated in a comprehensive health checkup program. IR was evaluated by the homeostasis model assessment of IR (HOMA-IR) and was considered to be present when the HOMA-IR score was >2. NAFLD was evaluated by ultrasound examination. Elevated alanine aminotransferase (ALT) was defined as >40 IU/L in men and >35 IU/L in women. Logistic regression was performed to determine the odds ratios (ORs) and 95% confidence intervals (95% CIs) for NAFLD, IR, and ALT according to categorized levels of WC. Results NAFLD was found in 2,553 (27.9%) of the participants (82.6% men, 17.4% women), while IR and elevated ALT were found in 17.2% (68.1% men, 31.9% women) and 10% (83% men, 17% women), respectively. After adjusting for confounding factors, the prevalence of NAFLD, IR, and elevated ALT was significantly associated with increases in WC quartile: highest quartile for NAFLD in men, OR=15.539, 95% CI=12.687-19.033; highest quartile for NAFLD in women, OR=48.732, 95% CI=23.918-99.288 (P<0.001); and highest quartile for IR in men, OR=17.576, 95% CI=13.283-23.255; highest quartile for IR in women, OR=11.078, 95% CI=7.813-15.708 (P<0.001); highest quartile for elevated ALT in men, OR=7.952, 95% CI=6.046-10.459; and highest quartile for elevated ALT in women, OR=8.487, 95% CI=4.679-15.395 (P<0.001). Conclusions WC contributes to IR and NAFLD in apparently healthy Korean adults, and thus may be an important factor in the development of IR and NAFLD. PMID:23837138

    Early menarche is strongly associated with adulthood obesity; however, the relationship between age at menarche and cardiovascular disease (CVD) in Korean women remains poorly understood. Here, we investigated the association between early menarche and risk factors for developing CVD during adulthood using a nationwide population database.In total, 12,336 women (weighted n = 17,483,406; weighted age, 45.7 years) who participated in the Korean National Health and Nutrition Examination Survey 2010 to 2013 were included in this study. Participants were scored using the National Cholesterol Education Program Adult Treatment Panel III criteria for metabolic syndrome. Risk of CVD was estimated using the 10-year Framingham Coronary Heart Disease Risk Point Scale (10-year FRS).Early menarche (≤11 years) was reported in 5.2% (weighted n = 917,493) of subjects. The weighted prevalences of metabolic syndrome and ≥20% 10-year FRS were 23.6% [95% confidence interval (95% CI), 22.7-24.6] and 7.7% (7.1-8.3), respectively. Women with early menarche reported a significantly higher body mass index and waist circumference, along with a higher prevalence of hypertension, diabetes, and metabolic syndrome than those with later menarche (≥13 years). Furthermore, the prevalence of women with a ≥10% or ≥20% 10-year FRS was higher in those with early menarche than in other groups after adjusting for age, smoking, education level, and menstruation. Logistic regression analyses controlling for these and other confounding factors revealed odds ratios of 2.29 (95% CI = 1.25-4.19) and 1.78 (0.96-3.30) for ≥10% and ≥20% 10-year FRS in women with early menarche, respectively, compared with those in the latest menarche group (≥17 years).Taken together, this nationwide study revealed that women with early menarche are at increased risks of metabolic syndrome and CVD. Early menarche may therefore represent an important marker for early preventive interventions. PMID

    Full Text Available With improved general health status many adults with intellectual disabilities (ID are living to old age, much like other adults. The World Health Organization has recognized the needs of this older population and identified the challenges they pose for governmental ministries and non-governmental organizations charged with planning, advocacy, financing, and delivery of specialty lifecare services and rehabilitation programs. These challenges include a range of issues normally confronting older adults, such as pensioning and financial security, changes in lifestyles associated with retirement and adaptations to living arrangements and housing, modifications in daily activities and community inclusion, changing physical and sensory abilities, and greater demands for support for aging families and other carers. As older adults with ID may also be affected by latelife or age-related conditions and begin to experience secondary impairments, these challenges may be more pronounced when encountered by NGOs located in countries with developing market economies. In these instances, the onus on promoting healthy aging will fall upon national entities which are responsible for targeting people with disabilities from infancy and childhood, and providing lifelong supports for adolescents, adults, and families. Ideally, if such efforts are undertaken early, they will lead to actions that can be undertaken to promote better health as people with ID age and ensure that the latter part of their lives are experienced as ‘quality of life years.’

    Full Text Available BACKGROUND: Sodium intake and albuminuria have important roles in blood pressure and renal progression. Although their relationship has been reported, the results have not been consistent and all studies have examined small populations. OBJECTIVE: This study investigated the role of the estimated 24-h urinary sodium excretion as a marker of sodium intake and albuminuria. DESIGN: This investigation included 5,187 individuals age 19 years and older from a cross-sectional, nationally representative, stratified survey: The Korea National Health and Nutrition Examination Survey (KNHANES V-2, in 2011. Albuminuria was defined as a urinary albumin/creatinine ratio ≥30 mg/g. The 24-h urinary sodium excretion was estimated from a spot urine. RESULTS: On classifying our participants into quartiles based on the estimated 24-h urinary sodium excretion, the prevalence of albuminuria increased with the 24-h urinary sodium excretion (5.3, 5.7, 7.5, and 11.8% in the first through fourth quartiles, respectively, p for trend <0.001. Even after adjusting for age, sex, diabetes, obesity, and hypertension, the significance persisted. In a multiple logistic regression analysis, the second and third quartiles of the estimated 24-h urinary sodium excretion were not associated with the presence of albuminuria with the first quartile as a control. However, the fourth quartile was significantly associated with the presence of albuminuria (odds ratio 1.61 [95% confidence interval 1.71-2.21], p = 0.003 after adjusting for age, sex, diabetes, obesity, and hypertension. CONCLUSIONS: These findings suggest that salt intake is associated with the presence of albuminuria in the general Korean adult population.

    This study was performed to estimate the effect of age at first calving and first two calving intervals on productive life and life time profit in Korean Holsteins. Reproduction data of Korean Holsteins born from 1998 to 2004 and lactation data from 276,573 cows with birth and last dry date that calved between 2000 and 2010 were used for the analysis. Lifetime profit increased with the days of life span. Regression of Life Span on Lifetime profit indicated that there was an increase of 3,800 Won (approximately $3.45) of lifetime profit per day increase in life span. This is evidence that care of each cow is necessary to improve net return and important for farms maintaining profitable cows. The estimates of heritability of age at first calving, first two calving intervals, days in milk for lifetime, lifespan, milk income and lifetime profit were 0.111, 0.088, 0.142, 0.140, 0.143, 0.123, and 0.102, respectively. The low heritabilities indicated that the productive life and economical traits include reproductive and productive characteristics. Age at first calving and interval between first and second calving had negative genetic correlation with lifetime profit (-0.080 and -0.265, respectively). Reducing age at first calving and first calving interval had a positive effect on lifetime profit. Lifetime profit increased to approximately 2,600,000 (2,363.6) from 800,000 Won ($727.3) when age at first calving decreased to (22.3 month) from (32.8 month). Results suggested that reproductive traits such as age at first calving and calving interval might affect various economical traits and consequently influenced productive life and profitability of cows. In conclusion, regard of the age at first calving must be taken with the optimum age at first calving for maximum lifetime profit being 22.5 to 23.5 months. Moreover, considering the negative genetic correlation of first calving interval with lifetime profit, it should be reduced against the present trend of increase

    Pulmonary oxygen uptake (V˙O2) kinetics and heart rate kinetics are influenced by age and fitness. Muscular V˙O2 kinetics can be estimated from heart rate and pulmonary V˙O2. In this study the applicability of a test using pseudo-random binary sequences in combination with a model to estimate muscular V˙O2 kinetics was tested. Muscular V˙O2 kinetics were expected to be faster than pulmonary V˙O2 kinetics, slowed in aged subjects and correlated with maximum V˙O2 and heart rate kinetics. 27 elderly subjects (73±3 years; 81.1±8.2 kg; 175±4.7 cm) participated. Cardiorespiratory kinetics were assessed using the maximum of cross-correlation functions, higher maxima implying faster kinetics. Muscular V˙O2 kinetics were faster than pulmonary V˙O2 kinetics (0.31±0.1 vs. 0.29±0.1 s; p=0.004). Heart rate kinetics were not correlated with muscular or pulmonary V˙O2 kinetics or maximum V˙O2. Muscular V˙O2 kinetics correlated with maximum V˙O2 (r=0.35; p=0.033). This suggests, that muscular V˙O2 kinetics are faster than estimates from pulmonary V˙O2 and related to maximum V˙O2 in aged subjects. In the future this experimental approach may help to characterize alterations in muscular V˙O2 under various conditions independent of motivation and maximal effort. PMID:27116341

    Seongwon Cha

    Full Text Available Obesity and osteoporosis share common physiological factors, including the presence of atherosclerosis, a risk factor for cardiometabolic disease, as well as a common progenitor that differentiates into both adipocytes and osteoblasts. Among the 23 polymorphisms associated with bone mineral density (BMD in recent genome-wide association studies (GWASs, an Osterix polymorphism has been identified and associated with childhood obesity in girls. Therefore, we focused on elucidating polymorphisms associated with adulthood obesity in a sex-dependent manner among the previously published BMD-associated polymorphisms from GWASs. We performed 2 screenings of 18 BMD-associated polymorphisms for obesity-related traits in 2,362 adults aged >20 years. We excluded 13 polymorphisms showing deviations from Hardy-Weinberg equilibrium or no association with obesity-related traits (body mass index, waist circumference (WC, and waist-to-hip ratio. Among 5 selected polymorphisms (rs9594738 of RANKL, rs17066364 of NUFIP1, rs7227401 of OSBPL1A, and rs1856057 and rs2982573 of ESR1 analyzed, 2 polymorphisms (rs9594738 and rs17066364 were associated with obesity-related traits. We found sex-dependent associations such that the 4 polymorphisms (excluding rs9594738 of RANKL were associated with abdominal traits such as WC and waist-to-hip ratio only in men. In addition, when the combined genetic risk score (GRS for WC increase was calculated with 4 SNPs (rs9594738, rs17066364, rs7227401, and rs1856057 exhibiting similar trends for both sexes, the magnitude of the GRS effect for the WC increase was larger in men than in women (effect size = 0.856 cm, P = 0.0000452 for men; effect size = 0.598 cm, P = 0.00228 for women. In summary, we found 4 polymorphisms, previously related to osteoporosis, to be associated to obesity-related traits in a sex-dependent manner in Korean adults, particularly in men.

    2000-06-01

    Hypermnesia is a net improvement in memory performance that occurs across tests in a multitest paradigm with only one study session. Our goal was to identify possible age-related differences in hypermnesic recall. We observed hypermnesia for young adults using verbal (Experiment 1) as well as pictorial (Experiment 2) material, but no hypermnesia for older adults in either experiment. We found no age-related difference in reminiscence (Experiments 1 and 2), though there was a substantial difference in intertest forgetting (Experiments 1 and 2). Older, relative to young, adults produced more forgetting, most of which occurred between Tests 1 and 2 (Experiments 1 and 2). Furthermore, older, relative to young, adults produced more intrusions. We failed to identify a relationship between intrusions and intertest forgetting. We suggest that the age-related difference in intertest forgetting may be due to less efficient reinstatement of cues at test by older adults. The present findings reveal that intertest forgetting plays a critical role in hypermnesic recall, particularly for older adults. PMID:10946539

    Objective The aims of this study were to investigate a simple method for assessing anterior-posterior jaw relationships via cone-beam computed tomography (CBCT) images taken in the natural head position (NHP) relative to the nasion true vertical plane (NTVP), and measure normative data in Korean adults with normal profiles. Methods Subjects were selected from patients presenting for third molar extraction and evaluated as having normal profiles by three examiners. The CBCT images of 80 subjects (39 males, 41 females) were taken in the NHP according to Solow and Tallgren's method. Linear measurements of the A-point, B-point, and Pog were calculated relative to the NTVP. Student's t-test was used to assess sexual differences in these measurements. Results The mean linear measurements of the A-point, B-point, and Pog relative to the NTVP were 0.18 mm (standard deviation [SD], 4.77 mm), −4.00 mm (SD, 6.62 mm), and −2.49 mm (SD, 7.14 mm) respectively in Korean males, and 1.48 mm (SD, 4.21 mm), −4.07 mm (SD, 6.70 mm) and −2.91 mm (SD, 7.25 mm) in Korean females respectively. There were no statistically significant differences between Korean males and females (p < 0.05). Conclusions Three-dimensional CBCT analysis using the NTVP is a simple and reliable method for assessing anterior-posterior skeletal relationships. PMID:27226962

    This report describes various factors on the IASCC of reactor internals in terms of fluence, stress, water chemistries and materials. Materials of each components of Korean nuclear power plants have been surveyed. A technical report for a management of reactor internals issued by EPRI was reviewed for a selection of most susceptible area among many components. Baffle former bolts are considered to be the most susceptible parts due to high irradiation level(fluence) and high tensile stress. Neutron fluence of Kori-1 and Kori-2 was calculated based on fuel exchange history, fuel performance and plant operation history. This report will be used for more advanced inspection and maintenance guidelines development by supplying inspection intervals and components (most susceptible regions) for the long term operation plants

    2009-12-01

    Full Text Available Abstract Background In Korea, the cutoff values of waist circumference (WC for the identification of metabolic syndrome (MetS were suggested to be 90 cm for men and 85 cm for women based on the analysis mainly in middle-aged adults. As aging is associated with increased fat, especially abdominal visceral fat, the cutoff value of WC may differ according to age. In addition, the usefulness of visceral abdominal fat area (VFA to predict MetS in the elderly has not been studied yet. We aimed to suggest WC and VFA criteria and to compare the predictability of WC and VFA to identify people at risk for MetS. Methods A total of 689 elderly subjects aged ≥63 years (308 men, 381 women were chosen in this cross-sectional study from an ongoing, prospective, population-based study, the Ansan Geriatric (AGE cohort study. VFA was measured by single slice abdominal computed tomography scanning. The metabolic risk factors except WC (plasma glucose, blood pressure, serum triglycerides and HDL cholesterol levels were defined using modified NCEP-ATP III criteria. We estimated the accuracy of VFA and WC for identifying at least two of these factors by receiver operating characteristic (ROC curve analysis. Results Two hundred three of 308 men and 280 of 381 women had ≥2 metabolic risk factors. The area under the ROC curve (AUC value for VFA to predict the presence of ≥2 metabolic risk factors was not significantly different from that for WC (men, 0.735 and 0.750; women, 0.715 and 0.682; AUC values for VFA and WC, respectively. The optimal cutoff points for VFA and WC for predicting the presence of ≥2 metabolic risk factors were 92.6 cm2 and 86.5 cm for men and 88.9 cm2 and 86.5 cm for women. Conclusion WC had comparable power with VFA to identify elderly people who are at risk for MetS. Elderly Korean men and women had very similar cutoff points for both VFA and WC measurements for estimating the risk of MetS. Age-specific cutoff point for WC might be

    Full Text Available BACKGROUND: We evaluated the association of regular physical exercise with the presence of non-alcoholic fatty liver disease (NAFLD and liver enzymes in relation to obesity and insulin resistance. METHODOLOGY/PRINCIPAL FINDINGS: A cross-sectional analysis was conducted in 72,359 healthy Korean adults without diabetes who participated in a comprehensive health check-up. Subjects who have been exercising regularly (more than 3 times per week, at least for 30 minutes each time and for consecutive 3 month were categorized into exercise group. All subjects were categorized into deciles based on their body mass index (BMI and we estimated the odds ratios (ORs for having NAFLD according to exercise regularity in each decile. The diagnosis of NAFLD was based on ultrasonography findings. Individuals with NAFLD (n = 19,921 were analyzed separately to evaluate ORs for having elevated liver enzymes based on regularity of exercise. The risk for NAFLD was significantly reduced in exercise group with age- and sex-adjusted ORs of 0.53-0.72 for all BMI deciles except at BMI categories of <19.6 and 20.7-21.6 kg/m(2. While no difference was seen in BMI between subjects in exercise and non-exercise group across the BMI deciles, the values of body fat percentage and metabolic risk factors differed. Among NAFLD patients, subjects in exercise group had a lower risk for having elevated liver enzymes with multivariable adjusted OR of 0.85 (95% CI 0.74-0.99, for AST and 0.74 (95% CI 0.67-0.81, for ALT than did subjects in non-exercise group. CONCLUSIONS/SIGNIFICANCE: Regular exercise was associated with a reduced risk for having NAFLD and decreased liver enzymes in patients with NAFLD, and this relationship was also independent of obesity.

    It has been hypothesized that prolonged exposure to high cortisol levels results in cognitive impairment. However, previous research into the relationship between cortisol and cognition has produced mixed results, most likely due to difficulties achieving valid estimates of long-term cortisol exposure based on salivary or plasma cortisol assessments at a single time point. Furthermore, there has been little research on the cognitive effects of long-term cortisol exposure in working-age adults. In the present study, hair samples were collected from 246 nurses (89.8% female) aged from 21 to 62 (M=42.0, SD=11.2). Hair cortisol concentrations (HCC) in the proximal 3-cm hair segment were analyzed providing an estimate of integrated cortisol secretion over the 3 month-period prior to hair sampling. Cognition was measured using a battery of 15 neuropsychological tests, measuring core dimensions of memory, inductive reasoning, processing speed, crystalized intelligence and major aspects of executive functioning. HCC was not significantly related to any of the cognitive abilities measured, either before or after controlling for potential moderators such as age, sex, education, health, well-being, work ability and burnout. Tests for nonlinear relationships also yielded non-significant results. Thus, despite the study being well powered, long term cortisol exposure did not appear to be related to cognitive performance in this sample of working-age adults, suggesting that long term cortisol exposure may be less relevant to cognition in younger and middle-aged adults than was previously thought.

    Background The number of cases of pertussis reported has increased gradually in the last decade. Pertussis vaccination is the most effective strategy for the prevention of infection. Despite the fact that young infants are at the highest risk for pertussis, the rate of tetanus-diphtheria-acellular pertussis (Tdap) vaccination is presumed to be very low among women of childbearing age in Korea. The purpose of this study was to investigate the perceptions of women of childbearing age regarding ...

  15. Adults' memories of growing up in the Atomic Age

    International Nuclear Information System (INIS)

    This dissertation was an empirical, qualitative, cross-age study of sixteen adults who grew up during the formative years of the Atomic Ages. The research objectives were to (1) examine the childhood determinants of adult thinking about nuclear weapons and (2) understand media's role in molding perceptions of the nuclear threat. Participants' childhood recollections of world news events were elicited through in-depth interviews. These data were analyzed in light of prior research comparing the childhood feelings and experiences of eight subjects, born 1935-1945, to those of eight subjects, born 1945-1955. The study demonstrated that participants nuclear anxiety differed between the two ages groups due to experiences growing up during the years of World War II versus the Cold War years. All participants had learned about atomic weapons at an early age form the media, which continued to be their primary educator regarding the nuclear facts of life. Few subjects, as children, ever discussed concerns about nuclear weapons with their parents. Few subjects, as parents, discussed concerns about nuclear weapons with their children

    Low levels of activity in hospital inpatients contribute to functional decline. Previous studies have shown low levels of activity in older inpatients, but few have investigated younger inpatients (aged intervention to enhance mobility. Using structured behavioral mapping protocols, participants were observed for 2-minute intervals throughout 4, 4-hour daytime observation periods. The proportion of time spent at different activity levels was calculated for each participant, and time spent standing, walking or wheeling was compared between age group and wards. There were 3272 observations collected on 132 participants (median, 30 per patient; range, 9-35). The most time was spent lying in bed (mean 57%), with 9% standing or walking. There were significant differences among wards, but no difference between older and younger subgroups. Low mobility is common in adult inpatients of all ages. Behavioral mapping provided measures suitable for use in quality improvement. Journal of Hospital Medicine 2016;11:289-291. © 2016 Society of Hospital Medicine. PMID:26797978

    2016-01-01

    We investigated beta-band intermuscular coherence (IMC) in 92 healthy adults stratified by decade of age, and analysed variability between and within subjects. In the dominant upper limb, IMC was estimated between extensor digitorum communis and first dorsal interosseous as well as between flexor digitorum superficialis and first dorsal interosseous. In the ipsilateral lower limb, IMC was measured between medial gastrocnemius and extensor digitorum brevis as well as between tibialis anterior and extensor digitorum brevis. Age-related changes in IMC were analysed with age as a continuous variable or binned by decade. Intrasession variance of IMC was examined by dividing sessions into pairs of epochs and comparing coherence estimates between these pairs. Eight volunteers returned for a further session after one year, allowing us to compare intrasession and intersession variance. We found no age-related changes in IMC amplitude across almost six decades of age, allowing us to collate data from all ages into an aggregate normative dataset. Interindividual variability ranged over two orders of magnitude. Intrasession variance was significantly greater than expected from statistical variability alone, and intersession variance was even larger. Potential contributors include fluctuations in task performance, differences in electrode montage and short-term random variation in central coupling. These factors require further exploration and, where possible, minimisation. This study provides evidence that coherence is remarkably robust to senescent changes in the nervous system and provides a large normative dataset for future applications of IMC as a biomarker in disease states.

    Full Text Available Background: Although a large body of evidence exists on the effect of smoking on lung age and pulmonary function, much less attention has been dedicated to using these effects as an effective strategy in smoking cessation. Objective: The present study was carried out to investigate the impact of smoking on lung age and ventilatory function in adult Saudi in order to use these effects in a future strategy for smoking cessation. Methods: Eighty one smoker students with their mean age 23.88 ± 2.7 years were enrolled in this study. Every student performed a ventilatory function tests in order to measure lung age, forced vital capacity (FVC, forced expiratory volume at the end of the first second (FEV1, FEV1/FVC ratio and peak expiratory flow rate PEFR. Results: The result showed significant deterioration in the mean value of FEV1, PEFR and the estimated lung age and a non-significant difference in the mean values of FVC. Conclusion: Smoking has a significant effect on ventilaroty function and deteriorating estimated lung age.

  19. Age-dependent difference in the computed tomography numbers of the normal parotid gland of Koreans

    International Nuclear Information System (INIS)

    To determine normal CT number range of parotid gland by analyzing the change by age increase and the difference among individuals and between both sexes in CT number of normal parotid gland. 134 subjects who took the CT scan between the period of Jan. 1996 and Dec. 1997 at Yonsei University, Dental Hospital were selected. Criteria for selection were that the patients must be within the normal range clinically and radiologically, and the entire parotid gland on the axial view must be shown. Among the axial views, the one showing the greatest parotid gland size was selected and its CT number was recorded. Also, CT numbers from both masseter muscle were recorded as its control. There was statistically significant correlation between CT number of right and left of parotid glands and masseter muscles. With the increase of age, there is a significant decrease in the CT number of parotid gland (p0.05). As age increases, CT number of parotid gland has a tendency to decrease, and there is no significant difference in the CT numbers between left and right parotid gland. Therefore in the CT scan of patients suspected of having an salivary gland disease of the parotid gland, to consider normal range of the age-dependent CT numbers of parotid gland and compare the CT numbers of the right and left parotid gland might be useful in diagnosing the disease.

  20. Old, down and out? Appearance, body work and positive ageing among elderly South Korean women.

    2016-08-01

    This article offers an as yet unexplored dimension of our current understanding of the ageing body in the context of contemporary South Korea. Drawing on interviews with twenty elderly women living in the greater Seoul metropolitan area, this article explores the role of appearance, body work, and the presentation of self in the women's everyday lived experiences. Existing research on the ageing female body in South Korea has primarily focused on the so-called noin munjae ('the elderly issue') discourse, within which the ageing body is framed as passive, undesirable, or out-of-control. Contrary to this, the elderly women's own narratives of everyday beauty practices suggest that the act of sustaining well-ordered appearance in later life allows for the enforcing of positive selves in the context of personal beauty and body work. Maintaining a positive appearance was shown to play an important part of their everyday lives, and functioned as a ritual of not only presenting an appearance that signified control over the ageing body, but to continue to enjoy it. The carefully calculated engagement with various non-surgical and surgical beauty practices also emerged as an embodied practice of mediating intersubjective social encounters through which self-esteem was engendered by evidencing the self's efforts to show respect to others. The findings of this study challenge dominant discourses in the west which present body work on the ageing female body as primarily self-indulgent, or driven by anxiety about the body's inability to fit within existing youthful beauty ideals.

    2016-09-01

    Older adults are at greater risk for homelessness today than at any time in recent history. Approximately one half of homeless individuals in America are older than 50, which has created serious challenges for how cities, governments, and health care providers care for homeless populations. Systems established in the 1980s to help care for homeless individuals were not designed to address problems of aging. It is critical that nurses and all health professionals have a better understanding of the unique needs and concerns of homeless older adults. Nurses can be an important part of the solution, not only through direct patient care but by advocating for improvements in care for this vulnerable population.

    Age-related change in episodic memory function is commonly reported in older adults. When detected on neuropsychological tests, it may still be difficult to distinguish normal from pathological changes. The present study investigates age-and sex-related changes in a group of healthy middle-aged and older adults, participating in a three-wave study on cognitive aging. The California Verbal Learning test (CVLT-II) was used to assess their episodic memory function. A cross-sectional analysis of results from the first wave showed higher performance in females than males, with a steeper age-related decline in males. This was confirmed in a longitudinal analysis using a mixed effects regression model, but with a lower age-related change and smaller difference between the sexes. Information about learning strategies and errors in the third wave turned out to contribute significantly to explain change in episodic memory function across the three waves. We argue that the results from the longitudinal analyses are generalizable to the population of healthy middle-aged and older individuals, and that they could be useful in guiding clinicians when evaluating individuals with respect to cognitive change.

    Full Text Available Aim: In Korea, obesity is more prevalent among men and lower socioeconomic groups. To explain this obesity disparity, we compared weight perception and weight control behavior across gender and socioeconomic status (SES. Methods: We analyzed data from 16,260 participants aged 20 years or older in a nationally representative cross-sectional survey. SES indicators included education and income levels. Weight under-perception was defined when participants considered themselves lighter than their measured BMI status. Either no active or inappropriate weight control (i.e., trying to gain weight in obese individuals was considered to be unhealthy patterns. Multivariate prevalence ratios were calculated using log-binomial regressions. Results: Men had a higher prevalence of weight under-perception (24.5 vs. 11.9% and unhealthy patterns of weight control behavior (57 vs. 40% than women. Low education level was associated with weight under-perception (ptrend = 0.022 in men, ptrend trend trend = 0.047 in men, ptrend Conclusion: Weight perception and weight control behavior significantly varied by gender and SES. Public actions should be directed toward improving perception and behavior of high-risk populations.

    Full Text Available Objectives: To determine the feasibility of using the activPAL3TM activity monitor, and, to describe the activity patterns of residential aged care residents. Design: Cross-sectional. Setting: Randomly selected aged care facilities within 100 km of the Gold Coast, Queensland, Australia. Participants: Ambulatory, older (≥60 years residential aged care adults without cognitive impairment. Measurements: Feasibility was assessed by consent rate, sleep/wear diary completion, and through interviews with staff/participants. Activity patterns (sitting/lying, standing, and stepping were measured via activPAL3TM monitors worn continuously for seven days. Times spent in each activity were described and then compared across days of the week and hours of the day using linear mixed models. Results: Consent rate was 48% (n = 41. Activity patterns are described for the 31 participants (mean age 84.2 years who provided at least one day of valid monitor data. In total, 14 (45% completed the sleep/wear diary. Participants spent a median (interquartile range of 12.4 (1.7 h sitting/lying (with 73% of this accumulated in unbroken bouts of ≥30 min, 1.9 (1.3 h standing, and 21.4 (36.7 min stepping during their monitored waking hours per day. Activity did not vary significantly by day of the week (p ≥ 0.05; stepping showed significant hourly variation (p = 0.018. Conclusions: Older adults in residential aged care were consistently highly sedentary. Feasibility considerations for objective activity monitoring identified for this population include poor diary completion and lost monitors.

    Background In evaluating hearing disability in medicolegal work, the apportionment of age- and gender-related sensorineural hearing loss should be considered as a prior factor, especially for the elderly. However, in the literature written in the English language no studies have reported on the age- and gender-related mean hearing threshold for the South Korean population. Objective This study aimed to identify the mean hearing thresholds in the South Korean population to establish reference data and to identify the age- and gender-related characteristics. Methods This study is based on the Korea National Health and Nutrition Examination Survey (KNHANES) 2010–2012, which was conducted by the Korean government, the data of which was disclosed to the public. A total of 15,606 participants (unweighted) representing 33,011,778 Koreans (weighted) with normal tympanic membrane and no history of regular or occupational noise exposure were selected and analyzed in this study. The relationship between the hearing threshold level and frequency, age, and gender was investigated and analyzed in a highly-screened population by considering the sample weights of a complex survey design. Results A gender ratio difference was found between the unweighted and the weighted designs: male:female, 41.0%: 59.0% (unweighted, participants) vs. 47.2%:52.8% (weighted, representing population). As age increased, the hearing threshold increased for all frequencies. Hearing thresholds of 3 kHz, 4 kHz, and 6 kHz showed a statistical difference between both genders for people older than 30, with the 4 kHz frequency showing the largest difference. This paper presents details about the mean hearing threshold based on age and gender. Conclusions The data from KNHANES 2010–2012 showed gender differences at hearing thresholds of 3 kHz, 4 kHz, and 6 kHz in a highly-screened population. The most significant gender difference in relation to hearing threshold was observed at 4 kHz. The hearing

    Full Text Available CONTEXT: It has been suggested that elevated serum ferritin is associated with several metabolic disorders. However, there is no reported study assessing any association between serum ferritin and sarcopenia despite the close relationship between sarcopenia and metabolic disorders. OBJECTIVE: We investigated whether serum ferritin was associated with sarcopenia in older Koreans. DESIGN AND SETTING: We conducted a cross-sectional study based on data acquired in the second and third years (2008-9 of the fourth Korean National Health and Nutrition Examination Survey. PARTICIPANTS: In total, 952 men (mean age 69.0 years and 1,380 women (mean age 69.3 years aged 60 years and older completed a body composition study using dual energy X-ray absorptiometry. MEASUREMENTS: Serum ferritin levels were measured. Sarcopenia was defined as an appendicular skeletal mass as a percentage of body weight that was less than two standard deviations below the gender-specific mean for young adults. RESULTS: Serum ferritin levels were lower in women than in men. Women with sarcopenia showed a higher level of serum ferritin than women without sarcopenia (men: without sarcopenia 115.7 ng/mL and with sarcopenia 134.4 ng/mL vs. women: without sarcopenia 70.7 ng/mL and with sarcopenia 85.4 ng/mL. The prevalence of sarcopenia increased as the tertile of serum ferritin increased. However, statistical significance was only seen in elderly women (1(st tertile 6.3%, 2(nd tertile 8.0%, 3(rd tertile 12.0%; p = 0.008. Without adjustment, compared with those in the lowest tertile of serum ferritin level, participants in the highest tertile had an odds ratio of 2.02 (95% confidence interval = 1.26-3.23 for sarcopenia in women. After adjusting for known risk factors, the OR for sarcopenia was 1.74 (95% CI = 1.02-2.97 in women. There was no statistically significant association between sarcopenia and serum ferritin tertiles in men. CONCLUSIONS: Elevated serum ferritin levels were

    Global personalized medicine demands the characterization of person-to-person and between-population differences in drug pharmacokinetics and pharmacodynamics. CYP2C9 pharmacokinetic pathway is subject to modulation by both genetic and environmental factors. CYP2C9 genotype-based dose recommendations (e.g., for warfarin) is advocated. However, the overall contribution of genotype for variation in enzyme activity may differ between populations. We evaluated the importance of ethnicity, genotype, smoking, body weight, age, and sex for CYP2C9 enzyme activity. CYP2C9 genotype and phenotype was determined in 148 Swedes and 146 Koreans using losartan as a probe. CYP2C9 enzyme activity was assessed using urinary losartan/metabolite E-3174 ratio. The frequency of CYP2C9 defective variant alleles (*2 and *3) was significantly higher in Swedes (10.8% and 12.5%) than in Koreans (0% and 5.8%). In matched genotypes, CYP2C9 enzyme activity was significantly lower in Swedes compared to Koreans (pspecific dose optimization and global personalized medicine. PMID:25977991

Materials and methods To analyze and compare the skeletal age with the Risser sign between scoliosis and non-scoliosis group, a cross-sectional study was done in 418 scoliosis (untreated, bracing or surgically and 256 non-scoliosis children of Korean origin. Relationship was found in both groups using Pearson correlation test. Results In scoliosis group, Pearson correlation exhibited significant correlation (p 2 = 0.791 for girls, 0.787 for boys and Risser sign and TW3 age (r2 = 0.718 for girls, 0.785 for boys. Non-scoliosis group also showed significant relationship (p 2 = 0.893 for girls, 0.879 for boys and Risser sign and TW3 age (r2 = 0.913 for girls, 0.895 for boys. Similarly, comparing Cobb angles of each patient according to their Risser staging, exhibited that if scoliosis remains untreated Cobb angle will increase with the increase in their Risser staging (r2 = 0.363 for girls, 0.443 for boys; p Conclusion Our results showed that chronological age is equally as reliable as skeletal age method to compare with Risser sign, and therefore, we do not mean to imply that only the Risser sign compared with skeletal age should be considered in the decision making in idiopathic as well as non-scoliosis patients of Korean ethnicity. Concomitant indicators such as menarchal period, secondary sex characteristics, and recent growth pattern will likely reinforce our data comparing Risser sign with skeletal age in decision making.

  17. Effect of aging on bone mass in adult women

    International Nuclear Information System (INIS)

    Total-body calcium was measured in 40 adult women by total-body neutron activation analysis (TBNAA). Procedures for normalizing the absolute calcium measurements for the parameters of size and age were developed in order to effect a direct comparison of women of age 30 to 78 yr. The normal total-body calcium (TB/sub Ca/) for an individual can be predicted by a formula developed in the present study to within +- 11 percent (1.62 SD) at the 90 percent confidence level. The TB/sub Ca/ loss can be characterized by two components: one with a slower rate, 0.37 percent/yr, and the other with a faster rate, 1.08 percent/yr. The latter, a more rapid postmenopausal loss, started at 50 to 60 yr and was superimposed on the slower rate of loss that started in the fourth decade and continued throughout life. The bone mineral content (BMC) of the radius, measured by the absorptiometric technique, correlated well with the total-body skeletal calcium in this population (r = 0.813, P less than .001). However, for intercomparisons of the BMC values of individuals, normalization of the BMC values for size and age is required, as it is for the TB/sub Ca/ data. Normalization provided by the ratio of BMC to radius width is not adequate for comparative studies

    Cognitive decline occurs with age and may be slowed by dietary measures, including increased intake of dietary phytochemicals. However, evidence from large and long-term studies of flavonol intake is limited. Dietary intakes of flavonols were assessed from a large biracial study of 10,041 subjects, aged 45-64, by analysis of a food frequency questionnaire administered at visit 1 of triennial visits. Cognitive function was assessed at visits 2 and 4 with the following three cognitive performance tests: the delayed word recall test, the revised Wechsler Adult Intelligence Scale digit symbol subtest, and the word fluency test of the Multilingual Aphasia Examination. The change in each score over 6 years was calculated, and a combined standardized change score was calculated. Generalized linear models controlled for age, ethnicity, gender, education level, energy intake, current smoking, physical activity, body mass index, diabetes, and vitamin C intake. Total flavonols across quintiles of intake were positively associated with preserved combined cognitive function (Pcognitive function was consistent for the three major individual flavonols in the diet, myricetin, kaempferol, and quercetin (each Pcognitive function over time.

    The primary objective of this study was to estimate the association between blood mercury levels and overweight in Korean adults. We analyzed cross-sectional data from 9228 participants (4283 men and 4945 women) who completed the Korean National Health and Nutrition Examination Survey (KNHANES), 2007-2013. The population was divided into two groups according to the body mass index (BMI) and waist circumference (WC). Blood mercury levels were analyzed using a gold amalgam method with a DMA-80 instrument, categorized into quartiles, and stratified by sex. After adjusting for all covariates, blood mercury was significantly associated with overweight in all subjects. According to the BMI criteria, the adjusted odds ratio of being in the highest blood mercury quartile was 1.75 (95 % confidence interval [CI], 1.53-2.01) overall, 2.09 (95 % CI, 1.71-2.55) in men, and 1.58 (95 % CI, 1.32-1.89) in women. According to the WC criteria, the adjusted odds ratio of being in the highest blood mercury quartile was 1.85 (95 % CI, 1.49-2.30) in men and 1.96 (95 % CI, 1.62-2.36) in women compared to the lowest quartile. Additionally, a trend in overweight across increasing blood mercury levels was observed by the p for trend test in the multiple diagnostic criteria. PMID:26458904

    Abstract The objective of this study was to examine the association of estimated glomerular filtration rate (eGFR) and urine albumin to creatinine ratio (ACR) with hearing impairment among diabetic adults in Korea. The study was based on data from Korea National Health and Nutrition Examination Survey 2011 to 2012. Participants were 1206 diabetic adults, aged over 19 years, who completed audiometric testing supervised by nationally certified clinicians. Hearing impairment was defined in three grades: no hearing impairment (pure-tone average 0–25 dB), slight hearing impairment (26–40 dB), and disabling hearing impairment (>40 dB) in the better ear at frequencies 0.5, 1, 2, 3, 4 and 6 kHz. Using logistic regression, risk of hearing impairment was assessed after having controlled for confounding factors. Higher levels of ACR and lower levels of eGFR correlated with an increase in percentage of disabling hearing impairment both unilaterally and bilaterally (P < 0.001). Controlling for possible confounding covariates, odds ratios for hearing impairment showed tendency to increase in higher ACR groups (P for trend = 0.029). Similar pattern was examined between eGFR and hearing impairment (P for trend = 0.006). Odds ratios were 1.981 (1.146, 3.424) for ACR Q4 and 2.773 (1.286, 5.983) for eGFR < 60 mL/min. Fall in eGFR and rise in ACR correlated with severity of hearing impairment. The association existed independently of age, sex, body mass index (BMI), smoking, drinking, exercise, new onset of diabetes, education, income, mental stress, noise exposure, and metabolic syndrome.

    Full Text Available Aim: This research sought to analyse older adults’ conceptualization of adjustment to aging (AtA, subjective age (SA and age representation (AR, adding a cross-national comparative perspective to aging well. Method: Questionnaires were completed, assessing participants’ background information. Semi-structured interviews were performed, addressing three core areas: SA, AtA and AR. Complete information on 231 older adults aged between 74-102 years (M = 83.1; SD = 6.692 from four different nationalities, was available. Data was subjected to content analysis. Results: Seven categories were identified to contribute to AtA: ‘accomplishment, personal fulfilment and future projects’, ‘occupation, profession, autonomy and leisure’, ‘health status, physical and intellectual functioning’, ‘valorisation of time and age’, ‘family, social and interpersonal attachment’, ‘stability, quality and financial situation’, and ‘sense of limit and existential issues’. Five categories were identified for SA: ‘with congruence’, ‘without concern’, ‘with apprehension’, ‘young-at-heart’ and ‘good enough’. For AR, eight emergent categories were found: ‘future investment’, ‘reconciliation with life’, ‘present challenge’, ‘regret about the past’, ‘dynamic life’, ‘with contentment’, ‘as an opportunity’ and ‘with dissatisfaction’. Conclusion: This research contributes for a better understanding of what defines AtA, SA and AR in older adults. Moreover, interventions and communication approaches in clinical practice and program development in health care context should focus on shared perceptions of aging well.

    Body dissatisfaction can be significantly detrimental to wellbeing. Little is known about older adults' body image, despite the fact that ageing causes unique bodily changes and that sociocultural pressures to resist these changes abound. We conducted six focus groups with a UK community sample of White British and South Asian older adults aged 65-92 years. Thematic analysis highlighted four themes: appearance indicates capability and identity; physical ability trumps appearance; felt pressures to age 'gracefully' while resisting appearance changes; and gender and cultural differences. These findings suggest that older adults' body image can have important implications for their wellbeing and merits researchers' attention. PMID:24776689

    2016-01-01

    This study was conducted to validate a food frequency questionnaire (FFQ) to assess vitamin K intake in clinical and research settings based on data from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES V). We collected a subset of data on informative food items using the 24-hour recall method from adults aged 19 to 64 years from KNHANES V. The cumulative percent contribution and cumulative multiple regression coefficients for vitamin K intake from each food were computed. Twenty-five foods items were selected for the FFQ to assess vitamin K intake. The FFQ was validated against intakes derived from a 5-day food record (5DR) (n = 48). To assess the reliability of the FFQ, participants completed the self-administered FFQ (FFQ1) and a second FFQ (FFQ2) after a 6-month period (n = 54). Data were analyzed using Pearson's correlation coefficients, the cross-classification method, and Bland-Altman plots. Mean intakes were similar for vitamin K between the FFQ and dietary records, with significant correlations observed (r = 0.652), and cross-classification analyses demonstrated no major misclassification of participants into intake quartiles. Bland-Altman plots showed no serious systematic bias between the administrations of the two dietary assessment methods over the range of mean intakes. FFQ reliability was high, with a Pearson's correlation coefficient of 0.560. This pilot study shows promising validation and reliability evidence for the use of this FFQ, which is focused on vitamin K intake in adults, as an efficient screening tool in clinical and research settings.

  11. DESCRIPTIVE STUDY OF HONORIFIC USE IN KOREAN EMAIL DISCOURSE

    Directory of Open Access Journals (Sweden)

    Jaegu Kim

    2016-07-01

    Full Text Available It is a relatively new field that examines how Korean culture affects Korean language use in terms of age difference in a corpus of computer mediated email discourse. The purpose of this descriptive study and experiment is to prove the close relationship between Korean language and culture. This paper shows the descriptive study of Korean culture in relation to language use. Korean culture acknowledges an inherent hierarchy with regard to age, and considers [+age] as relating socially to [+power]. When younger Koreans converse with older ones, they express different morpho-syntactic patterns, which is an age complex. The main task of the experiment was to examine the way through which the age complex is reflected by Korean honorific linguistic system in email discourse. I asked 15 Korean native speakers between the ages of 20 to 25 to write emails expressing an impositive request to [+age (46-50 years old], [-age (below 25 years old] and [=age] recipients. The results show significant differences in the use of grammatical features in emails written to [+age] recipients, as compared to emails written to [-age] and [=age] recipients. The implication of the findings is that the cultural values that are attached to age and aging in the Korean society affects Koreans’ language use, which means Korean language and culture are closely intermingled.

    Full Text Available Purpose: Previous studies suggest that the concentration of 25-hydroxyvitamin D [25(OHD] in cord blood may show an inverse association with respiratory tract infections (RTI during childhood. The aim of the present study was to examine the influence of 25(OHD concentrations in cord blood on infant RTI in a Korean birth cohort. Methods: The levels of 25(OHD in cord blood obtained from 525 Korean newborns in the prospective COhort for Childhood Origin of Asthma and allergic diseases were examined. The primary outcome variable of interest was the prevalence of RTI at 6-month follow-up, as diagnosed by pediatricians and pediatric allergy and pulmonology specialists. RTI included acute nasopharyngitis, rhinosinusitis, otitis media, croup, tracheobronchitis, bronchiolitis, and pneumonia. Results: The median concentration of 25(OHD in cord blood was 32.0 nmol/L (interquartile range, 21.4 to 53.2. One hundred and eighty neonates (34.3% showed 25(OHD concentrations less than 25.0 nmol/L, 292 (55.6% showed 25(OHD concentrations of 25.0&#8211;74.9 nmol/L, and 53 (10.1% showed concentrations of ?#247;5.0 nmol/L. Adjusting for the season of birth, multivitamin intake during pregnancy, and exposure to passive smoking during pregnancy, 25(OHD concentrations showed an inverse association with the risk of acquiring acute nasopharyngitis by 6 months of age (P for trend= 0.0004. Conclusion: The results show that 89.9% of healthy newborns in Korea are born with vitamin D insufficiency or deficiency (55.6% and 34.3%, respectively. Cord blood vitamin D insufficiency or deficiency in healthy neonates is associated with an increased risk of acute nasopharyngitis by 6 months of age. More time spent outdoors and more intensified vitamin D supplementation for pregnant women may be needed to prevent the onset of acute nasopharyngitis in infants.

    Distortion of intracellular oxidant and antioxidant balances appears to be a common feature that underlies in age-related male sexual impairment. Therefore regulating oxidative defense mechanisms might be an ideal approach in improving male sexual dysfunctions. In the present study, the effect of Korean red ginseng aqueous extract (KRG) on age-induced testicular dysfunction in rats was investigated. KRG (200mg/kg) mixed with regular pellet diet was administered orally for six months and the morphological, spermatogenic and antioxidant enzyme status in testis of aged rats (18months) were evaluated. Data indicated a significant change in morphology and decrease in spermatogenesis-related parameters in aged rats (AC) compared with young rats (YC). Sperm number, germ cell count, Sertoli cell count and Sertoli cell index were significantly (p<0.05) restored in KRG-treated aged rat groups (G-AC). Further the increased lipid peroxidation as measured by malondialdehyde (p<0.05), and altered enzymatic (superoxide dismutase, glutathione peroxidase, glutathione S-transferase, glutathione reductase and catalase) and non-enzymatic (reduced glutathione, ascorbic acid and α-tocopherol) antioxidants (p<0.05) were attenuated by KRG treatment in aged rats to near normal levels as in YC groups. Furthermore, proteomic analysis demonstrated differential expression of selected proteins such as phosphatidylinositol transfer protein, fatty acid binding protein-9, triosephosphate isomerase-1 and aldehyde (aldose) reductase-1in aged rats was significantly (p<0.05) protected by KRG treatment. In conclusion, long-term administration of KRG restored aging-induced testicular ineffectiveness in rats by modulating redox proteins and oxidative defense mechanisms. PMID:25980653

    Aging is associated with a decline in multiple aspects of cognitive function, with spatial cognition being particularly sensitive to age-related decline. Environmental stressors, such as high-fat diet (HFD) exposure, that produce a diabetic phenotype and metabolic dysfunction may indirectly lead to exacerbated brain aging and promote the development of cognitive deficits. The present work investigated whether exposure to HFD exacerbates age-related cognitive deficits in adult versus aged mice. Adult (5 months old) and aged (15 months old) mice were exposed to control diet or HFD for three months prior to, and throughout, behavioral testing. Anxiety-like behavior in the light-dark box test, discrimination learning and memory in the novel object/place recognition tests, and spatial learning and memory in the Barnes maze test were assessed. HFD resulted in significant gains in body weight and fat mass content with adult mice gaining significantly more weight and adipose tissue due to HFD than aged mice. Weight gain was attributed to food calories sourced from fat, but not total calorie intake. HFD increased fasting insulin levels in all mice, but adult mice showed a greater increase relative to aged mice. Behaviorally, HFD increased anxiety-like behavior in adult but not aged mice without significantly affecting spatial cognition. In contrast, aged mice fed either control or HFD diet displayed deficits in novel place discrimination and spatial learning. Our results suggest that adult mice are more susceptible to the physiological and anxiety-like effects of HFD consumption than aged mice, while aged mice displayed deficits in spatial cognition regardless of dietary influence. We conclude that although HFD induces systemic metabolic dysfunction in both adult and aged mice, overall cognitive function was not adversely affected under the current experimental conditions.

    Full Text Available Aging is associated with a decline in multiple aspects of cognitive function, with spatial cognition being particularly sensitive to age-related decline. Environmental stressors, such as high-fat diet (HFD exposure, that produce a diabetic phenotype and metabolic dysfunction may indirectly lead to exacerbated brain aging and promote the development of cognitive deficits. The present work investigated whether exposure to HFD exacerbates age-related cognitive deficits in adult versus aged mice. Adult (5 months old and aged (15 months old mice were exposed to control diet or HFD for three months prior to, and throughout, behavioral testing. Anxiety-like behavior in the light-dark box test, discrimination learning and memory in the novel object/place recognition tests, and spatial learning and memory in the Barnes maze test were assessed. HFD resulted in significant gains in body weight and fat mass content with adult mice gaining significantly more weight and adipose tissue due to HFD than aged mice. Weight gain was attributed to food calories sourced from fat, but not total calorie intake. HFD increased fasting insulin levels in all mice, but adult mice showed a greater increase relative to aged mice. Behaviorally, HFD increased anxiety-like behavior in adult but not aged mice without significantly affecting spatial cognition. In contrast, aged mice fed either control or HFD diet displayed deficits in novel place discrimination and spatial learning. Our results suggest that adult mice are more susceptible to the physiological and anxiety-like effects of HFD consumption than aged mice, while aged mice displayed deficits in spatial cognition regardless of dietary influence. We conclude that although HFD induces systemic metabolic dysfunction in both adult and aged mice, overall cognitive function was not adversely affected under the current experimental conditions.

    An investigation was conducted to study and evaluate soil fertility in Korean larch plantations of different ages ranging from 15 to 52 years old in Jincang Forest Farm of Jilin Province. The soil physico-chemical properties were carried out in larch plantations of different stand ages. Soil fertility of these stands was further assessed by principal component analysis method. The results show that the stand age has significant effects on soil physico-chemical properties. With the increase of stand age, the soil bulk density and the soil pH firstly increase and then decrease, but the soil water content and the nutrient content change with diverse variation degrees in larch plantations of different stand ages. There are close correlations between soil properties. Soil moisture content, soil organic matter, total N, total P and rapidly available K had very significant negative correlations with soil bulk density, but significant positive correlations with soil pH. The correlations between soil nutrient contents are significant positive, but in different degrees. The soil fertility assessment by principal component analysis shows soil fertility order of Korean larch plantation; middle-age forest>young forest>mature forest>nearly mature forest. Therefore, adjusting stand density of young forest and middle-age forest, controlling cutting intensity and replanting nearly mature forest and mature forest with long-term located observations are the suggested methods to improve the general soil fertility of Korean larch plantations.%基于吉林省汪清林业局金仓林场中15~52年生长白落叶松(Larix olgensis Herry.)人工林土壤肥力调查数据,分析和比较了不同林龄长白落叶松人工林的土壤物理和化学性质,并采用主成分分析评价了其土壤肥力状况.结果表明:①林龄对长白落叶松人工林土壤理化性质影响显著,随着林龄的增加,土壤密度和土壤pH值先降低后增加,而土壤含水量和养分

    Full Text Available To explore older adults’ perceptions of subjective age and adjustment to ageing and to analyse the correlational structure of the pre-categories in our study: subjective age, indicators of adjustment to ageing and of personal age perception. An exploratory, descriptive mixed-methods design was utilised. A purposive sampling method was used to select 154 older adults aged between 75 and 99 years from three different nationalities. Semi-structured interviews were performed, addressing two core areas: subjective age and adjustment to ageing. Data was subjected to content analysis. Representation of the correlational structure of the precategories in our study (subjective age and indicators of adjustment to ageing were analysed by a Multiple Correspondence Analysis. Standardised instruments measured regular cognitive abilities. Five categories derived from interviews for subjective age: ‘adapted’, ‘disconnected’, ‘old’, ‘youthful’ and ‘tolerant’. A total of seven categories emerged as indicators of adjustment to ageing: ‘social networking’, ‘health’, ‘time perspective’, ‘spirituality’, ‘financial autonomy’, ‘professional activities’ and ‘fulfilment and leisure’. These results supported a model for each pre-category. Subjective age was explained by a two-factor model: ‘age-conscientious’ and ‘youthful’. A three-dimensional model formed by ‘reconciled’, ‘satisficers’ and ‘maximisers’ was indicated as a best-fit solution for adjustment to ageing. A three-dimensional overall model for PAP was formed by ‘age-cognisant’, ‘fulfilled’ and ‘satisficers’. The findings highlighted the underdeveloped potential of subjective age, adjustment to ageing and a personal age perception overall model for this population. Enhancing subjective age and adjustment to ageing might be an important target to improve older adults’ interventions’ outcomes.

    Older adults represent the fastest-growing age demographic of the population. Physiological changes associated with primary aging and concurrent chronic disease adversely impact functional capacity, health outcomes, and quality of life. For these reasons, there is a national emphasis for healthcare providers to improve the health, function, and quality of life of older adults to preserve independent living and psychological well-being. The benefits of regular physical activity or exercise with regard to aging and disease are indisputable, yet many clinicians do not prescribe exercise to older adults. This reluctance may be attributable to a lack of knowledge regarding appropriate exercise prescription for older adults in light of the potential risks and benefits of various doses and types of exercise. In addition, clinicians and patients may have concerns about potential health considerations relevant to older adults such as comprehensive pre-exercise screening and exercise-drug interactions. In light of this, the following review presents (1) guidelines for exercise prescription in older adults and modification of these guidelines for patients with the most common age-associated comorbidities; (2) recommendations for pre-exercise screening prior to initiating an exercise program in older adults; (3) considerations for older adults on one or more medications; and (4) common barriers to adopting and maintaining exercise in an older population. Our goal is to provide a framework that clinicians can follow when prescribing exercise in older adults while considering the unique characteristics and concerns present in this population.

    Full Text Available Adults with alcohol use disorders (AUDs show marked immediate reward selection (or “Now” bias in intertemporal choice tasks. This Now bias persists long into abstinence, suggesting an irreversible consequence of chronic alcohol abuse or a pre-existing AUD intermediate phenotype. However, some data show substantial Now bias among emerging adults (18-25, regardless of drinking behavior, suggesting age-dependent effects on Now bias. The objectives of the present study were to determine 1 whether Now bias is greater among emerging adults relative to adults, 2 whether any such age effect on Now bias is diminished in sub-clinical heavy alcohol users, and 3 whether having a problem drinking first degree relative is independently associated with elevated Now bias. To achieve these objectives, we used an intertemporal choice task to quantify Now bias in n=237 healthy participants (ages 18-40; 50% female, and a wide range of non-zero alcohol use, based on the Alcohol Use Disorders Identification Test (AUDIT. We found that among non-heavy drinkers, Now bias inversely correlated with age; this relationship was not present among heavy drinkers. We found no significant relationship between AUDIT score and Now bias among emerging adults, but AUDIT scores and Now bias were positively correlated among 26-40 year olds.

    Previous studies that examined age differences in hypermnesia reported inconsistent results. The present experiment investigated whether the different study materials in these studies were responsible for the inconsistency. In particular, the present experiment examined whether the use of a video, as opposed to words and pictures, would eliminate previously reported age differences in hypermnesia. Fifteen college students and 15 older adults viewed a 3-minute video clip followed by two free-recall tests. The results indicated that older adults, as a whole, did not show hypermnesia. However, when older adults were divided into low and high memory groups based on test 1 performance, the high memory group showed hypermnesia whereas the low memory group did not show hypermnesia. The older adults in the low memory group were significantly older than the older adults in the high memory group - indicating that hypermnesia is inversely related to age in older adults. Reminiscence did not show an age-related difference in either the low or high memory group whereas inter-test forgetting did show an age difference in the low memory group. As expected, older adults showed greater inter-test forgetting than young adults in the low memory group. Findings from the present experiment suggest that video produces a pattern of results that is similar to the patterns obtained when words and pictures are used as study material. Thus, it appears that the nature of study material is not the source of inconsistency across the previous studies. PMID:17681108

    Full Text Available In order to maintain health during middle age and achieve successful aging, it is important to elucidate and prevent risk factors of middle-age stroke. This study investigated high risk groups of stroke in middle age population of Korea and provides basic material for establishment of stroke prevention policy by analyzing sudden perception of speech/language problems and clusters of multiple risk factors. This study analyzed 2,751 persons (1,191 males and 1,560 females aged 40–59 who participated in the 2009 Korea National Health and Nutrition Examination Survey. Outcome was defined as prevalence of stroke. Set as explanatory variables were age, gender, final education, income, marital status, at-risk drinking, smoking, occupation, subjective health status, moderate physical activity, hypertension, and sudden perception of speech and language problems. A prediction model was developed by the use of a C4.5 algorithm of data-mining approach. Sudden perception of speech and language problems, hypertension, and marital status were significantly associated with stroke in Korean middle aged people. The most preferentially involved predictor was sudden perception of speech and language problems. In order to prevent middle-age stroke, it is required to systematically manage and develop tailored programs for high-risk groups based on this prediction model.

    Purpose: Lesbian, gay, bisexual, and transgender (LGBT) people are a health disparate population as identified in Healthy People 2020. Yet, there has been limited attention to how LGBT older adults maintain successful aging despite the adversity they face. Utilizing a Resilience Framework, this study investigates the relationship between physical and mental health-related quality of life (QOL) and covariates by age group. Design and Methods: A cross-sectional survey of LGBT adults aged 50 and older (N = 2,560) was conducted by Caring and Aging with Pride: The National Health, Aging, and Sexuality Study via collaborations with 11 sites across the U.S. Linear regression analyses tested specified relationships and moderating effects of age groups (aged 50–64; 65–79; 80 and older). Results: Physical and mental health QOL were negatively associated with discrimination and chronic conditions and positively with social support, social network size, physical and leisure activities, substance nonuse, employment, income, and being male when controlling for age and other covariates. Mental health QOL was also positively associated with positive sense of sexual identity and negatively with sexual identity disclosure. Important differences by age group emerged and for the old–old age group the influence of discrimination was particularly salient. Implications: This is the first study to examine physical and mental health QOL, as an indicator of successful aging, among LGBT older adults. An understanding of the configuration of resources and risks by age group is important for the development of aging and health initiatives tailored for this growing population. PMID:25213483

  12. Evaluation of some hormonal levels related to age in adult and aged male rats exposed to gamma radiation

    International Nuclear Information System (INIS)

    As we grow older, the ability to produce most hormones in adequate amounts declined. This decline in natural hormones production coincides with nearly every age-related health problems. The present work aims to evaluate the levels of some hormones related to age namely dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulphate (DHEA-s) and melatonin and also the alteration in lipid fractions using male rats subjected to acute sublethal dose of gamma radiation. This study included thirty two male albino rats divided into two main groups; adult group (four months old) and aged group (20 months old). Each group was divided into two subgroups; control group and group irradiated at a dose level of 5 Gray whole body gamma irradiation. Blood samples were collected from both adult and aged groups 3 days post-irradiation after 16 hours fasting. As related to age, the aged group showed significant decrease in DHEA, DHEA-s and melatonin levels and significant increase in total cholesterol, triglycerides, LDL-c and cholesterol/HDL ratio when compared to adult group. Concerning the effect of gamma radiation, the irradiated adult group showed significant (P<0.01) decrease in DHEA, DHEA-s and melatonin levels by values equal to -32.2%, - 39.8% and -67.9%, respectively, and nonsignificant changes in lipids concentrations except for LDL-c level, which showed significant (P<0.05) increase at +58.2 % in irradiated adult group as compared to adult controls. On the other hand, exposure to irradiation of aged rats did not affect the hormonal levels assayed except for the level of DHEA-s which was decreased significantly (P<0.05) by -26.4% as compared to control aged rats. Also, total cholesterol and LDL-c levels were increased significantly (P<0.01) by +17.1% and +27.4 %, respectively in irradiated rats as compared to control aged group. It could be concluded that y-radiation obviously accelerates the aging process in adults suggesting the need for protective agents to overcome the

    Older adults with functional limitations may be at higher risk for depression and suicidal ideation compared to their counterparts without such limits. This study examined the structural relationships between functional limitation, depression, suicidal ideation, and coping strategies in older Korean immigrants. Using data from 220 community dwelling Korean immigrants (age ≧ 65) in Los Angeles County, path analysis was conducted to test the study hypotheses. The resulting model accounted for 56% of the variance in suicidal ideation, with functional limitation making significant contribution to suicidal ideation. Meanwhile, depression, which had the strongest direct effects on suicidal ideation, also played a significant role in mediating between functional limitation and suicidal ideation. Furthermore, adaptive coping was significantly associated with both functional limitation and suicidal ideation. Findings provide implications for implementing suicide-prevention programs for older Korean immigrants, especially those living with functional disability. PMID:25864581

  4. Change of cerebral blood flow distribution and vascular reserver according to age in Koreans measured by Tc-99m HMPAO brain SPECT

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the normal values of regional cerebral blood flow (rCBF) and cerebrovascular reserve (CVR) in normal children to aged volunteers using Tc-99m HMPAO. Thirty four right-handed normal volunteers (20 males, 14 females, mean age 40.3±24.9 years, range 4 to 82 years) were underwent rest/acetazolamide (ACZ) brain SPECT using Tc-99m HMPAO and the sequential injection and subtraction method. rCBF was estimated on the basis of a semiquantitative approach by means of right/left ratio, region/cerebellum and region to whole brain ratios in frontal, parietal, temporal, and occipital lobes, basal ganglia, thalami, and cerebellum. CVR was measured by means of % perfusion increase calculated as % mean count change compared to rest rCBF in each regions. Mean values of right to left ratios range from 1.004 to 1.018. rCBF was highest in cerebellum and lowest in basal ganglia and thalami. Frontal and temporal rCBF decreased while occipital and thalamic rCBF increased according to age. No sexual difference of rCBF was noted. Mean CVR was 29.9±12.9%. Mean CVR significantly increased to late teens, and declined thereafter. After 6th decade, CVR in both frontal lobes, left parietal lobe and right basal ganglia decreased significantly with advancing age. There was no sexual difference of CVR. Quantitative assessment of CVR was possible by ACZ Tc-99m MHPAO brain SPECT. It revealed that rCBF and CVR changed according to age in normal Korean volunteers. There was no sexual difference

    Full Text Available OBJECTIVES: To extend existing research on the US health disadvantage relative to Europe by studying the relationships of disability with age from midlife to old age in the US and four European regions (England/Northern and Western Europe/Southern Europe/Eastern Europe including their wealth-related differences, using a flexible statistical approach to model the age-functions. METHODS: We used data from three studies on aging, with nationally representative samples of adults aged 50 to 85 from 15 countries (N = 48225: the US-American Health and Retirement Study (HRS, the English Longitudinal Study of Ageing (ELSA and the Survey of Health, Ageing and Retirement in Europe (SHARE. Outcomes were mobility limitations and limitations in instrumental activities of daily living. We applied fractional polynomials of age to determine best fitting functional forms for age on disability in each region, while controlling for socio-demographic characteristics and important risk factors (hypertension, diabetes, obesity, smoking, physical inactivity. RESULTS: Findings showed high levels of disability in the US with small age-related changes between 50 and 85. Levels of disability were generally lower in Eastern Europe, followed by England and Southern Europe and lowest in Northern and Western Europe. In these latter countries age-related increases of disability, though, were steeper than in the US, especially in Eastern and Southern Europe. For all countries and at all ages, disability levels were higher among adults with low wealth compared to those with high wealth, with largest wealth-related differences among those in early old age in the USA. CONCLUSIONS: This paper illustrates considerable variations of disability and its relationship with age. It supports the hypothesis that less developed social policies and more pronounced socioeconomic inequalities are related to higher levels of disability and an earlier onset of disability.

    Full Text Available IntroductionFew studies have prospectively assessed the explanatory effects of demographics, clinical conditions, treatment modality, and general lifestyle behaviors on glycemic control in large heterogeneous samples of middle-aged and older adults with type 2 diabetes. We hierarchically examined these factors, focused especially on the effects of modifiable factors (ie, general lifestyle behaviors, and compared predictive patterns between middle-aged and older adults.MethodsWe used nationally representative data from the 1998 and 2000 Health and Retirement Study (HRS and the HRS 2003 Diabetes Study. We analyzed data from 379 middle-aged adults (aged 51-64 y and 430 older adults (aged ≥65 y who self-reported having type 2 diabetes at baseline.ResultsAmong middle-aged adults, demographic factors and clinical conditions were the strongest predictors of hemoglobin A1c (HbA1c levels. However, among older adults, treatment modality (diet only, oral medication, or insulin only or in combination with other regimens significantly affected HbA1c levels. Lifestyle (physical activity, smoking, drinking, and body weight control, independent of the effects of demographics, clinical conditions, and treatment modality, significantly affected HbA1c levels. An increase of 1 healthy behavior was associated with a decrease in HbA1c levels of more than 1 percentage point.ConclusionOur findings provide support for current diabetes guidelines that recommend a lifestyle regimen across the entire span of diabetes care and highlight the need to help both sociodemographically and clinically disadvantaged middle-aged adults with type 2 diabetes as well as older adults who exhibit poor adherence to medication recommendations to achieve better glycemic control.

    Vaccination is the main strategy for preventing influenza infection. However, vaccine efficacy is influenced by several factors, including age and health status. The efficacy of the influenza vaccine is much lower (17% to 53%) in individuals over 65 yr of age compared with young adults (70% to 90%). Therefore, increasing vaccine efficacy remains a challenge for the influenza vaccine field. In this study, we investigated the impact of supplementing vaccination with the dietary intake of Korean...

    A long-standing concern has been whether epilepsy contributes to cognitive decline or so-called 'epileptic dementia'. Although global cognitive decline is generally reported in the context of chronic refractory epilepsy, it is largely unknown what percentage of patients is at risk for decline. This review is focused on the identification of risk factors and characterization of aberrant cognitive trajectories in epilepsy. Evidence is found that the cognitive trajectory of patients with epilepsy over time differs from processes of cognitive ageing in healthy people, especially in adulthood-onset epilepsy. Cognitive deterioration in these patients seems to develop in a 'second hit model' and occurs when epilepsy hits on a brain that is already vulnerable or vice versa when comorbid problems develop in a person with epilepsy. Processes of ageing may be accelerated due to loss of brain plasticity and cognitive reserve capacity for which we coin the term 'accelerated cognitive ageing'. We believe that the concept of accelerated cognitive ageing can be helpful in providing a framework understanding global cognitive deterioration in epilepsy. PMID:26900650

  8. Age-related face processing bias in infancy: evidence of perceptual narrowing for adult faces.

    2014-02-01

    Recent data demonstrate a perceptual processing advantage for adult faces in both adults and young children, suggesting that face representation is shaped by visual experience accumulated with different face-age groups. As for species and race, this age bias may emerge during the first year of life as part of the general process of perceptual narrowing, given the extensive amount of social and perceptual experience accumulated with caregivers and/or other adult individuals. Using infant-controlled habituation and visual-paired comparison at test, two experiments were carried out to examine 3- and 9-month-olds' ability to discriminate within adult and infant faces. Results showed that, when they are provided with adequate time to visually compare the stimuli during test trials (Experiment 2), 3-month-olds exhibit above-chance discrimination of adult and infant faces. Instead, 9-month-olds discriminate adult faces but not infant faces (Experiments 1 and 2). Results provide the first evidence of age-related face processing biases in infancy, and show that by 9 months face representations tune to adult human faces. PMID:24374735

    2013-09-01

    Aims. Youth and young adult suicide has increasingly appeared on international vital statistics as a rising trend of concern in age-specific mortality over the past 50 years. The reporting of suicide deaths in 5-year age bands, which has been the international convention to date, may mask a greater understanding of year-on-year factors that may accelerate or ameliorate the emergence of suicidal thoughts, acts and fatal consequences. The study objective was to identify any year-on-year period of increased risk for youth and young adult suicide in the UK and Ireland. Methods. Collation and examination of international epidemiological datasets on suicide (aged 18-35) for the UK and Ireland 2000-2006 (N = 11 964). Outcome measures included the age distribution of suicide mortality in international datasets from the UK and Ireland, 2000-2006. Results. An accelerated pattern of risk up to the age of 20 for the UK and Ireland which levels off moderately thereafter was uncovered, thus identifying a heretofore unreported age-related epidemiological transition for suicide. Conclusions. The current reporting of suicide in 5-year age bands may conceal age-related periods of risk for suicide. This may have implications for suicide prevention programmes for young adults under age 21. PMID:23149246

  14. Alcohol consumption by aging adults in the United States: health benefits and detriments.

    Ferreira, Maria Pontes; Weems, M K Suzy

    2008-10-01

    The most rapidly growing segment of the US population is that of older adults (> or =65 years). Trends of aging adults (those aged > or =50 years) show that fewer women than men consume alcohol, women consume less alcohol than men, and total alcohol intake decreases after retirement. A U- or J-shaped relationship between alcohol intake and mortality exists among middle-aged (age 45 to 65 years) and older adults. Thus, alcohol can be considered either a tonic or a toxin in dose-dependent fashion. Active areas of research regarding the possible benefits of moderate alcohol consumption among aging individuals include oxidative stress, dementia, psychosocial functioning, dietary contributions, and disease prevention. Yet, due to the rising absolute number of older adults, there may be a silent epidemic of alcohol abuse in this group. Dietary effects of moderate and excessive alcohol consumption are reviewed along with mechanisms by which alcohol or phytochemicals modify physiology, mortality, and disease burden. Alcohol pharmacokinetics is considered alongside age-related sensitivities to alcohol, drug interactions, and disease-related physiological changes. International guidelines for alcohol consumption are reviewed and reveal that many nations lack guidelines specific to older adults. A review of national guidelines for alcohol consumption specific to older adults (eg, those offered by the National Institute on Alcohol Abuse) suggests that they may be too restrictive, given the current literature. There is need for greater quantification and qualification of per capita consumption, consumption patterns (quantity, frequency, and stratified combinations), and types of alcohol consumed by older adults in the United States.

    Objective The objective of this study was to examine the role of social support in predicting depression in caregivers of adults aging with spinal cord injuries (SCI). Design Cross-sectional secondary data analyses were conducted for this study. Setting Participants were recruited from multiple community locations in Pittsburgh, PA and Miami, FL. Subjects Community-dwelling caregivers of aging adults with SCI (N=173) were interviewed as part of a multisite randomized clinical trial. Main measures The Center for Epidemiological Studies Depression Scale measured caregiver depression symptom levels. A hierarchical multiple regression analysis examined the effect of social support (social integration, received social support, and negative social interactions) on depressive symptoms levels for the caregivers of adults aging with SCI, controlling for demographic characteristics and caregiving characteristics. Results Caregivers were, on average, 53 years old (SD=15) and care-recipients were 55 years old (SD=13). Average Center for Epidemiological Studies Depression Scale scores indicated that sixty-nine (40%) caregivers had significant depressive symptoms (mean 8.69, SD=5.5). Negative social interactions (β̂ =.27, P<.01) and social integration (β̂ =−.25, P<.01) were significant independent predictors of depressive symptom levels in caregivers of adults aging with SCI. Conclusions Findings demonstrate that negative social interactions and social integration are associated with burden in caregivers of adults aging with SCI. Negative social interactions and social integration should be investigated in assessments and interventions intended to target caregiver depressive symptom levels. PMID:23117350

    Many older people perceive ageing negatively, describing it in terms of poor or declining health and functioning. These perceptions may be related to older adults' health. The aim of this review was to synthesise existing research on the relationship between older adults' perceptions of ageing and their health and functioning. A systematic search was conducted of five electronic databases (ASSIA, CINAHL, IBSS, MEDLINE and PsycINFO). Citations within identified reports were also searched. Observational studies were included if they included perceptions of ageing and health-related measures involving participants aged 60 years and older. Study selection, data extraction and quality appraisal were conducted using predefined criteria. Twenty-eight reports met the criteria for inclusion. Older adults' perceptions of ageing were assessed with a variety of measures. Perceptions were related to health and functioning across seven health domains: memory and cognitive performance, physical and physiological performance, medical conditions and outcomes, disability, care-seeking, self-rated health, quality of life and death. How ageing is perceived by older adults is related to their health and functioning in multiple domains. However, higher quality and longitudinal studies are needed to further investigate this relationship. PMID:26527056

    This study was performed to build region-specific reference ranges of peripheral blood lymphocyte subsets for Chinese healthy adults from the young to the elderly and analyze the trends of changes in lymphocyte subsets for evaluating the impact of age on the values. 151 healthy adults aged 19-86 were recruited based on the SENIEUR protocol. Three sets of reference ranges were finally built applicable for the healthy young (19-44 years), middle-aged (45-64 years) and elder adults (>65). Comparisons in parameters among the three cohorts showed that e statistically significant increase in CD16CD56+ NK cell was observed between the middle-aged and elder cohorts, whereas for the majority of the parameters, a significant decline was observed between the young and the middle-aged cohorts.Further results showed that inverse correlations were observed between the age and CD19+ B, CD3+T,CD3+CD4+1, CD4+CD45RA+CD62L+ naTve T cell and CD4+CD28+/CD4+, while the positive one was identified between the age end the NK cell. These significant changes of the most of immune parameters provided evidence for immunosenescence. Notably, T cell activation markers of CD8+CD38+ and CD8+HLA-DR+ showed reverse trends of association with age, which provides a clue for further researches on the mechanisms underlying the paradoxical clinical presentation of the elder patients.

    2016-06-01

    Age-related macular degeneration (AMD) causes a progressive loss of photoreceptors in the macula. It is the most common cause of legal blindness in the United States, and some form of AMD is thought to affect more than 9 million individuals. Risk factors include older age, smoking, dyslipidemia, obesity, white race, female sex, and a family history of AMD. There are two types of advanced AMD: nonexudative (dry or geographic atrophy) and exudative (wet or neovascular). Both cause progressive central vision loss with intact peripheral vision. Nonexudative AMD accounts for 80% to 90% of all advanced cases, and more than 90% of patients with severe vision loss have exudative AMD. On ophthalmoscopic examination, early findings include drusen (ie, yellow deposits in the retina). Prominent choroidal vessels, subretinal edema, and/or hemorrhage are seen in wet AMD. Regular eye examinations, visual field testing, fluorescein angiography, and optical coherence tomography are used for diagnosis and to guide management. There is no specific therapy for dry AMD, but antioxidant supplementation may be helpful. Intravitreal injection of a vascular endothelial growth factor inhibitor is the treatment of choice for wet AMD. Optical aids and devices can help to maximize function for patients with AMD.

    Full Text Available Background. Few studies have prospectively examined whether depressive symptoms and other risk factors are associated with a higher risk of suicide death in individuals other than high-risk populations such as psychiatric patients and individuals with self-harm histories. The purpose of the study is to prospectively examine whether depressive symptoms assessed by the Beck Depression Inventory (BDI are associated with greater risk of suicide death and whether depressive symptoms and other risk factors are independent predictors of suicide in general-risk populations. Another aim is to evaluate the sensitivity of the BDI for predicting suicide death. Methods. 10,238 Korean Vietnam War veterans (mean age: 56.3 years who participated in two surveys in 2001 were followed up for suicide mortality over 7.5 years. Results. 41 men died by suicide. Severely depressed participants had a higher adjusted hazard ratio (aHR = 3.4; 95% CI [1.5–7.7] of suicide than non-to-moderately depressed ones. Higher suicide risk was associated with more severe depressive symptoms (p for trend = 0.009. After adjustment for depressive symptoms and other factors, very poor health, low education, and past drinking were associated with higher suicide risk, while good health, body mass index, and marital status were not associated with suicide. The sensitivity at the cut-off score of 31 for detecting suicide was higher during the earlier 3.5 years of the follow-up (75%; 95% CI [50–90] than during the latter 4 years (60%; 95% CI [41–76]. Conclusions. Depressive symptoms are a strong independent predictor and very poor health, low education, and drinking status may be independent predictors of future suicide. The BDI may have acceptable diagnostic properties as a risk assessment tool for identifying people with depression and suicidal potential among middle-aged men.

    Full Text Available Protein-energy wasting is common in patients with end-stage kidney disease. However, few studies have examined the relationship between early stages of chronic kidney disease (CKD and sarcopenia.We conducted a cross-sectional study based on data in the Korea National Health and Nutrition Examination Survey, 2008-2011. In total, 11,625 subjects aged 40 years or older who underwent dual-energy X-ray absorptiometry were analyzed. Sarcopenia was defined based on values of appendicular skeletal muscle mass as a percentage of body weight (ASM/Wt two standard deviations below the gender-specific mean for young adults. Estimated glomerular filtration rates (eGFR were calculated using the CKD-EPI equation.Mean age, body mass index (BMI, and HOMA-IR were higher and caloric intake, physical activity, and vitamin D level were lower in the sarcopenia groups in both men and women. As the stage of CKD increased, the prevalence of sarcopenia increased, even in the early stages of CKD (normal and CKD1, 2, and 3-5: 2.6%, 5.6%, and 18.1% in men and 5.3%, 7.1%, and 12.6% in women, respectively; p < 0.001. In addition, a correlation analysis showed that GFR and ASM/Wt had significant correlations in both men and women. Logistic regression analyses, after adjusting for age, BMI, caloric intake, log(physical activity, vitamin D level, and log(HOMA-IR, showed that the odds ratio for sarcopenia with respect to CKD 3-5 was 1.93 (95% CI = 1.02-3.68 in men but was not statistically significant in women.The prevalence of sarcopenia was higher in elderly Korean patients with even mildly reduced kidney function. Stage of CKD was associated with an increased prevalence of sarcopenia in men but not women. Thus, we should evaluate the risk of sarcopenia and work to prevent it, even in patients with early CKD.

    Birdsong is a complex learned vocal behavior that relies on auditory experience for development. However, it appears that among different species of close-ended songbirds, there are some variations in the necessity of auditory feedback for maintaining stereotyped aduh song. In zebra finches, the deterioration of adult songs following deafness depends on the birds' age. It is unknown whether this age effect is a general ride in other avian species as well. Therefore, we chose Bengalese finches, whose songs show more complexity and have much heavier dependency on auditory feedback than that of zebra finches, to compare the degree of song degradation after heating loss in old (over 18 months old) and young adult birds (5-6 months old). We found that beth syllable sequence and syllable phonology were much leas severely affected by deafening in old adults than that in young ones. Moreover, young adults almost lost their capability to sing trills over 6 months following deafening, while old birds continued to sing plenty of trills and trilled syllables after the same period of deafening. Our results suggest that age plays an important role in affecting the dependency of adult song maintenance on auditory feedback in Bengalese finches. Furthermore, the age dependency may be a general phenomenon in different species of close-ended songbirds.

    A major goal in aging research is to improve health during aging. In the case of mice, genetic manipulations that shorten or lengthen telomeres result, respectively, in decreased or increased longevity. Based on this, we have tested the effects of a telomerase gene therapy in adult (1 year of age) and old (2 years of age) mice. Treatment of 1- and 2-year old mice with an adeno associated virus (AAV) of wide tropism expressing mouse TERT had remarkable beneficial effects on health and fitness,...

    It is largely unknown how age impacts cognition in autism spectrum disorder (ASD). We investigated whether age-related cognitive differences are similar, reduced or increased across the adult lifespan, examined cognitive strengths and weaknesses, and explored whether objective test performance is related to subjective cognitive challenges. Neuropsychological tests assessing visual and verbal memory, generativity, and theory of mind (ToM), and a self-report measure assessing cognitive failures were administered to 236 matched participants with and without ASD, aged 20-79 years (IQ > 80). Group comparisons revealed that individuals with ASD had higher scores on visual memory, lower scores on generativity and ToM, and similar performance on verbal memory. However, ToM impairments were no longer present in older (50+ years) adults with ASD. Across adulthood, individuals with ASD demonstrated similar age-related effects on verbal memory, generativity, and ToM, while age-related differences were reduced on visual memory. Although adults with ASD reported many cognitive failures, those were not associated with neuropsychological test performance. Hence, while some cognitive abilities (visual and verbal memory) and difficulties (generativity and semantic memory) persist across adulthood in ASD, others become less apparent in old age (ToM). Age-related differences characteristic of typical aging are reduced or parallel, but not increased in individuals with ASD, suggesting that ASD may partially protect against an age-related decrease in cognitive functioning. Despite these findings, adults with ASD experience many cognitive daily challenges, which highlights the need for adequate social support and the importance of further research into this topic, including longitudinal studies.

    Catalase (CAT) is an important antioxidant enzyme and is crucial in modulating synaptic plasticity in the brain. In this study, CAT expression as well as neuronal distribution was compared in the hippocampus among young, adult and aged mice and rats. Male ICR mice and Sprague Dawley rats were used at postnatal month (PM) 1, PM 6 and PM 24 as the young, adult and aged groups, respectively (n=14/group). CAT expression was examined by immunohistochemistry and western blot analysis. In addition, neuronal distribution was examined by NeuN immunohistochemistry. In the present study, the mean number of NeuN‑immunoreactive neurons was marginally decreased in mouse and rat hippocampi during aging, although this change was not identified to be significantly different. However, CAT immunoreactivity was significantly increased in pyramidal and granule neurons in the adult mouse and rat hippocampi and was significantly decreased in the aged mouse and rat hippocampi compared with that in the young animals. CAT protein levels in the hippocampus were also lowest in the aged mouse and rat hippocampus. These results indicate that CAT expression is significantly decreased in the hippocampi of aged animals and decreased CAT expression may be closely associated with aging. PMID:27221506

  11. Intrinsic brain connectivity related to age in young and middle aged adults.

    Michelle Hampson

    Full Text Available Age-related variations in resting state connectivity of the human brain were examined from young adulthood through middle age. A voxel-based network measure, degree, was used to assess age-related differences in tissue connectivity throughout the brain. Increases in connectivity with age were found in paralimbic cortical and subcortical regions. Decreases in connectivity were found in cortical regions, including visual areas and the default mode network. These findings differ from those of recent developmental studies examining earlier growth trajectories, and are consistent with known changes in cognitive function and emotional processing during mature aging. The results support and extend previous findings that relied on a priori definitions of regions of interest for their analyses. This approach of applying a voxel-based measure to examine the functional connectivity of individual tissue elements over time, without the need for a priori region of interest definitions, provides an important new tool in brain science.

    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.

    This article explores potential differences in yoga practice between middle-and older-aged adults. A health belief - life course model frames this research, and a mixed-methods analytic strategy is employed to examine life course pathways into yoga and motivations to practice, as well as perceived barriers and health benefits. For the quantitative analyses, a convenience sample of 452 participants was collected using an online questionnaire. For the qualitative analyses, face-to-face interviews were conducted with a sub-set of 20 participants. Unique differences between the age groups (both current age and age when started yoga) as well as by gender were found for selected pathways, reasons/motivations, and barriers to engage in yoga as well as for perceived health benefits. In addition, results underscore the importance of informational cues and social linkages that affect how individuals adopt and experience yoga. Implications for health promotion programs that target older adults are discussed. PMID:27086476

    Full Text Available Background: Functional ankle instability (FAI is the tendency of the foot to ′give way′. Identification of Functional Ankle Instability questionnaire (IdFAI is a newly developed questionnaire to detect whether individuals meet the minimum criteria necessary for inclusion in an FAI population. However, the reliability of the questionnaire was studied only in a restricted age group. Aim: The purpose of this investigation was to examine the reliability of IdFAI across different age groups in adults. Materials and Methods: One hundred and twenty participants in the age group of 20-60 years consisting of 30 individuals in each age group were asked to complete the IdFAI on two occasions. Test-retest reliability was evaluated by intraclass correlation coefficient (ICC 2,1 . Results: The study revealed that IdFAI has excellent test-retest reliability when studied across different age groups. The ICC 2,1 in the age groups 20-30 years, 30-40 years, 40-50 years and 50-60 years was 0.978, 0.975, 0.961 and 0.922, respectively with Cronbach′s alpha >0.9 in all the age groups. Conclusion: The IdFAI can accurately predict if an individual meets the minimum criterion for FAI across different age groups in adults. Thus, the questionnaire can be applied over different age groups in clinical and research set-ups.

    Interest in mind wandering (MW) has grown in recent years, but few studies have assessed this phenomenon in older adults. The aim of this study was to assess age-related differences between young, young-old and old-old adults in MW using two versions of the sustained attention to response task (SART), one perceptual and one semantic. Different indicators were examined (i.e., reported MW episodes and behavioral indices of MW such as response time latency and variability, incorrect response and omission errors). The relationship between MW, certain basic mechanisms of cognition (working memory, inhibition and processing speed), cognitive failures and intrusive thoughts in everyday life was also explored. Findings in both versions of the SART indicated that older adults reported a lower frequency of MW episodes than young adults, but some of the behavioral indices of MW (response time variability, incorrect response and omission errors) were higher in old-old adults. This seems to suggest that MW becomes less frequent with aging, but more pervasive and detrimental to performance. Our results also indicated that the role of age and cognitive mechanisms in explaining MW depends on the demands of the SART task considered. PMID:24291121

    Adults as well as infants have the capacity to discriminate languages based on visual speech alone. Here, we investigated whether adults' ability to discriminate languages based on visual speech cues is influenced by the age of language acquisition. Adult participants who had all learned English (as a first or second language) but did not speak French were shown faces of bilingual (French/English) speakers silently reciting sentences in either language. Using only visual speech information, adults who had learned English from birth or as a second language before the age of 6 could discriminate between French and English significantly better than chance. However, adults who had learned English as a second language after age 6 failed to discriminate these two languages, suggesting that early childhood exposure is crucial for using relevant visual speech information to separate languages visually. These findings raise the possibility that lowered sensitivity to non-native visual speech cues may contribute to the difficulties encountered when learning a new language in adulthood. PMID:24312020

    The goal of the current investigation was to analyze ability emotional intelligence (EI) in a large cross-sectional sample of Spanish adults (N = 12,198; males, 56.56%) aged from 17 to 76 years (M = 37.71, SD = 12.66). Using the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT), which measures ability EI according to the 4 branches of the Mayer and Salovey EI model. The authors examined effects of gender on ability EI, as well as the linear and quadratic effects of age. Results suggest that gender affects the total ability EI score as well as scores on the 4 EI branches. Ability EI was greater in women than men. Ability EI varied with age according to an inverted-U curve: Younger and older adults scored lower on ability EI than middle-aged adults, except for the branch of understanding emotions. These findings strongly support the idea that both gender and age significantly influence ability EI during aging. (PsycINFO Database Record PMID:27570984

    The Patient Protection and Affordable Care Act, which will provide health insurance to nearly all U.S. citizens and improve the quality of health insurance, will particularly benefit adults ages 50 to 64, a group suffering from extended unemployment and a loss of employer health benefits. Several early provisions that go into effect in 2010, including preexisting condition insurance plans, will provide transitional assistance for adults who have struggled to gain health insurance. The biggest improvements will come in 2014 through a significant expansion in eligibility for Medicaid and the creation of health insurance exchanges with subsidized private insurance for people with low and moderate incomes. Of the 8.6 million adults ages 50 to 64 who were uninsured in 2009, up to 6.8 million may gain subsidized insurance through Medicaid and the exchanges and 1.4 million with higher incomes will have access to comprehensive health plans with new consumer protections.

    This study investigated developmental trends associated with the Deese/Roediger-McDermott false-memory effect, the role of distinctive information in false-memory formation, and participants' subjective experience of true and false memories. Children (5- and 7-year-olds) and adults studied lists of semantically associated words. Half of the participants studied words alone, and half studied words accompanied by pictures. There were significant age differences in recall (5-year-olds evinced more false memories than did adults) but not in recognition of critical lures. Distinctive information reduced false memory for all age groups. Younger children provided with distinctive information, and older children and adults regardless of whether they viewed distinctive information, expressed higher levels of confidence in true than in false memories. Source attributions did not significantly differ between true and false memories. Implications for theories of false memory and memory development are discussed. PMID:12220049

    Distension of peripheral veins in humans elicits a pressor and sympathoexcitatory response that is mediated through group III/IV skeletal muscle afferents. There is some evidence that autonomic reflexes mediated by these sensory fibers are blunted with increasing age, yet to date the venous distension reflex has only been studied in young adults. Therefore, we tested the hypothesis that the venous distension reflex would be attenuated in middle-aged compared with young adults. Nineteen young (14 men/5 women, 25 ± 1 yr) and 13 middle-aged (9 men/4 women, 50 ± 2 yr) healthy normotensive participants underwent venous distension via saline infusion through a retrograde intravenous catheter in an antecubital vein during limb occlusion. Beat-by-beat blood pressure, muscle sympathetic nerve activity (MSNA), and model flow-derived cardiac output (Q), and total peripheral resistance (TPR) were recorded throughout the trial. Mean arterial pressure (MAP) increased during the venous distension in both young (baseline 83 ± 2, peak 94 ± 3 mmHg; P 0.05). These findings suggest that peripheral venous distension elicits a pressor and sympathetic response in middle-aged adults similar to the response observed in young adults. PMID:27053648

    Several studies have shown a reduced efficacy of influenza vaccines in the elderly compared to young adults. In this study, we evaluated the immunogenicity and protective efficacy of a commercially available inactivated influenza vaccine (Fluzone®) in young adult and aged mice. C57/BL6 mice were administered a single or double immunization of Fluzone® with or without CpG and challenged intranasally with H1N1 A/California/09 virus. A double immunization of Fluzone® adjuvanted with CpG elicited the highest level of protection in young adult mice which was associated with increases in influenza specific IgG, elevated HAI titres, reduced viral titres and lung inflammation. In contrast, the vaccine schedule which provided fully protective immunity in young adult mice conferred limited protection in aged mice. Antigen presenting cells from aged mice were found to be less responsive to in vitro stimulation by Fluzone and CpG which may partially explain this result. Our data are supportive of studies that have shown limited effectiveness of influenza vaccines in the elderly and provide important information relevant to the design of more immunogenic vaccines in this age group.

    Full Text Available In the United Kingdom, Bangladeshi women have the lowest self-reported levels of physical activity and some of the highest levels of metabolic disease of all ethnic groups. To better understand these risks for poor health we employed life course and intergenerational hypotheses to predict lower body physical function in a sample of 121 Bangladeshi mothers (40–70 years old and one of their adult daughters (17–36 years old living in Bangladesh or in the UK. For the mothers, older age and shorter knee height predicted reduced lower body physical function. Knee height is a biomarker of nutrition and health status between birth and puberty. Age at first birth did not have a significant effect. For daughters, older age and migration to the UK predicted reduced lower body physical function. We controlled for total stature and fatness in all analyses. UK-born daughters were taller than BD-born daughters living in the UK, mostly due to differences in knee height. These new findings support previous research indicating that early life health and adequate nutritional status, along with appropriate adult physical activity and diet, may decrease risks for poor physical function, morbidity, and premature mortality.

    Population ageing is rapidly becoming a global issue and will have a major impact on health policies and programmes. The World Health Organization’s Study on global AGEing and adult health (SAGE) aims to address the gap in reliable data and scientific knowledge on ageing and health in low- and middle-income countries. SAGE is a longitudinal study with nationally representative samples of persons aged 50+ years in China, Ghana, India, Mexico, Russia and South Africa, with a smaller sample of adults aged 18–49 years in each country for comparisons. Instruments are compatible with other large high-income country longitudinal ageing studies. Wave 1 was conducted during 2007–2010 and included a total of 34 124 respondents aged 50+ and 8340 aged 18–49. In four countries, a subsample consisting of 8160 respondents participated in Wave 1 and the 2002/04 World Health Survey (referred to as SAGE Wave 0). Wave 2 data collection will start in 2012/13, following up all Wave 1 respondents. Wave 3 is planned for 2014/15. SAGE is committed to the public release of study instruments, protocols and meta- and micro-data: access is provided upon completion of a Users Agreement available through WHO’s SAGE website (www.who.int/healthinfo/systems/sage) and WHO’s archive using the National Data Archive application (http://apps.who.int/healthinfo/systems/surveydata).

    International Nuclear Information System (INIS)

    Mature adult (3-6 mo old) and aged (2 yr old) male ICR mice were injected with 10 to 100 mg/kg morphine, s.c. The ED50 values for running behavior (as measured using Stoelting activity monitors and having each mouse serve as its own control) representing 5 times control activity was approximately 7.5 mg/kg for aged mice and approximately 17.5 mg/kg for the mature adults. The ED50 values for analgesia 1 hr after morphine administration using the tail-flick method (max. response time = 8 sec) were approx. 70 mg/kg for the aged mice and 15 mg/kg for the mature adults. One hour after injecting 3H-morphine at doses of 30 and 100 mg/kg, 0.13 and 0.14% of the doses appeared in brains of aged and mature adult mice, respectively. Regional distribution of the morphine was the same for both age groups. Expressed as percent of total brain morphine, it was as follows: cortex, 30%; midbrain, 18%; cerebellum, 17%; medulla, 12%; pons, 9%; striatum, 8% and periaqueductal gray, 6%. Expressed as g morphine/g tissue for the 2 doses, the distribution was; periaqueductal gray, 30 and 80; striatum, 9 and 34; medulla, 6 and 20 pons; 5 and 19; cerebellum, 4 and 13; midbrain 2.5 and 8.5 and cortex, 2 and 8. These results suggest that the differences in response to morphine by the two age groups were due to age-related differences in opioid receptor populations and/or affinities

    A cross-sectional study was conducted to explore the prevalence and severity of health-related complaints perceived by adult males of Hong Kong by using the Hong Kong Traditional Chinese versions of the Aging males' symptoms (AMS) scale and the 5-dimensional and 3-level European Quality of life (EQ-5D-3L) questionnaire. A total of 825 adult males aged 40 years or above were surveyed, and observed that 80% of the population was living with little-to-mild levels of aging symptoms with mean total scores ranged between 26.02 ± 7.91 and 32.99 ± 7.91 in different age groups. Such symptoms were correlated with age, especially for the somato-vegetative and sexual symptoms. The most severe AMS symptoms were observed in the oldest age group at 70 years or above, with 76%, 34% and 70% living with moderate-to-severe levels of somato-vegetative, psychological and sexual symptoms, respectively. The result was highly correlated with the EQ-5D-3L questionnaire. Secondly, the Hong Kong Aging males' symptoms (AMS) scale was shown to have good reliability with test-retest coefficient at 0.79 (ranged 0.66-0.87) and Cronbach's alpha coefficient at 0.88 (ranged 0.70-0.84). In summary, the population of Hong Kong male adults was commonly living with little-to-mild levels of aging symptoms, whereas their severity was correlated with age. PMID:27068128

    Two studies were conducted to examine age differences in the impact of motivation in a social cognitive task. We tested the hypothesis that aging is associated with an increase in the selective engagement of cognitive resources in support of performance. Different-aged adults read descriptions of 2 people in order to determine which was better suited for a particular job. These descriptions contained behaviors that were either consistent or inconsistent with the job, and participants performed the task under conditions of high versus low accountability. Examination of memory for behavioral information revealed that accountability disproportionately affected older adults' performance, with the locus of this effect being in conscious recollection processes. This supports the aforementioned selective engagement hypothesis by demonstrating that the differential impact of the motivational manipulation was based in deliberative memory processes.

    2016-08-01

    A growing body of research demonstrates that older individuals tend to score differently on personality measures than younger adults. However, recent research using item response theory (IRT) has questioned these findings, suggesting that apparent age differences in personality traits merely reflect artifacts of the response process rather than true differences in the latent constructs. Conversely, other studies have found the opposite-age differences appear to be true differences rather than response artifacts. Given these contradictory findings, the goal of the present study was to examine the measurement equivalence of personality ratings drawn from large groups of young and middle-aged adults (a) to examine whether age differences in personality traits could be completely explained by measurement nonequivalence and (b) to illustrate the comparability of IRT and confirmatory factor analysis approaches to testing equivalence in this context. Self-ratings of personality traits were analyzed in two groups of Internet respondents aged 20 and 50 (n = 15,726 in each age group). Measurement nonequivalence across these groups was negligible. The effect sizes of the mean differences due to nonequivalence ranged from -.16 to .15. Results indicate that personality trait differences across age groups reflect actual differences rather than merely response artifacts. PMID:25773456

    The estimation of chronologic age based on the stages of third-molar development was evaluated by using the eight stages (A-H) method of Demirjian and the third-molar development was compared, in terms of sex and age, with results of previous studies. The samples consisted of 291orthopantomograms from young Chinese subjects of known chronologic age and sex (including 139males with a mean age of 14.67±3.62 y and 152 females with a mean age of 14.85±3.70 y). Statistical analysis was performed by employing the Mann-Whitney U-test and the t-test. Regression analysis was conducted to obtain regression formulas for calculating dental age from the chronologic age. Our results showed statistically significant differences (P<0.05) in third-molar development between males and females, at the calcification stages D, E and H. And a strong correlation was found between age and third-molar development in both males (r2=0.65) and females (r2=0.61). New equations (Age=8.76+1.32 Development stage) for estimating chronologic age were derived. It is concluded that third-molar genesis took place earlier in males than in females. The use of third molars as a developmental marker is appropriate in young adults of Central China. The formula obtained in the present study can be used as a guide for estimation of dental maturity and a standard for age estimation for young adults of Central China.

    This study was performed to build region-specific reference ranges of peripheral blood lymphocyte subsets for Chinese healthy adults from the young to the elderly and analyze the trends of changes in lymphocyte subsets for evaluating the impact of age on the values.151 healthy adults aged 19-86 were recruited based on the SENIEUR protocol.Three sets of reference ranges were finally built applicable for the healthy young(19-44 years),middle-aged(45-64 years) and elder adults(≥65).Comparisons in parameters among the three cohorts showed that a statistically significant increase in CD16CD56+ NK cell was observed between the middle-aged and elder cohorts,whereas for the majority of the parameters,a significant decline was observed between the young and the middle-aged cohorts.Further results showed that inverse correlations were observed between the age and CD19+ B,CD3+ T,CD3+CD4+ T,CD4+CD45RA+CD62L+ nave T cell and CD4+CD28+/CD4+,while the positive one was identified between the age and the NK cell.These significant changes of the most of immune parameters provided evidence for immunosenescence.Notably,T cell activation markers of CD8+CD38+ and CD8+HLA-DR+ showed reverse trends of association with age,which provides a clue for further researches on the mechanisms underlying the paradoxical clinical presentation of the elder patients.

    Older adults have been shown to avoid negative and prefer positive information to a higher extent than younger adults. This positivity bias influences their information processing as well as decision-making. We investigate age-related positivity bias in charitable giving in two studies. In Study 1 we examine motivational factors in monetary donations, while Study 2 focuses on the emotional effect of actual monetary donations. In Study 1, participants (n = 353, age range 20-74 years) were asked to rate their affect toward a person in need and then state how much money they would be willing to donate to help this person. In Study 2, participants (n = 108, age range 19-89) were asked to rate their affect toward a donation made a few days prior. Regression analysis was used to investigate whether or not the positivity bias influences the relationship between affect and donations. In Study 1, we found that older adults felt more sympathy and compassion and were less motivated by negative affect when compared to younger adults, who were motivated by both negative and positive affect. In Study 2, we found that the level of positive emotional reactions from monetary donations was higher in older participants compared to younger participants. We find support for an age-related positivity bias in charitable giving. This is true for motivation to make a future donation, as well as affective thinking about a previous donation. We conclude that older adults draw more positive affect from both the planning and outcome of monetary donations and hence benefit more from engaging in monetary charity than their younger counterparts.

    The older adult population is growing rapidly in the USA and it is expected that by 2040 the number of adults ≥ 65 years of age will have increased by about 50%. With the growth of this subpopulation, oral health status, and periodontal status in particular, becomes important in the quest to maintain an adequate quality of life. Poor oral health can have a major impact, leading to tooth loss, pain and discomfort, and may prevent older adults from chewing food properly, often leading to poor nutrition. Periodontitis is monitored in the USA at the national level as part of the Healthy People 2020 initiative. In this report, we provide estimates of the overall burden of periodontitis among adults ≥ 65 years of age and after stratification according to sociodemographic factors, modifiable risk factors (such as smoking status), the presence of other systemic conditions (such as diabetes) and access to dental care. We also estimated the burden of periodontitis within this age group at the state and local levels. Data from the National Health and Nutrition Examination Survey 2009/2010 and 2011/2012 cycles were analyzed. Periodontal measures from both survey cycles were based on a full-mouth periodontal examination. Nineteen per cent of adults in this subpopulation were edentulous. The mean age was 73 years, 7% were current smokers, 8% lived below the 100% Federal Poverty Level and periodontitis in Utah (62.3%) and New Hampshire (62.6%) and the highest in New Mexico, Hawaii, and the District of Columbia each with a prevalence of higher than 70%. Overall, periodontitis is highly prevalent in this subpopulation, with two-thirds of dentate older adults affected at any geographic level. These findings provide an opportunity to determine how the overall health-care management of older adults should consider the improvement of their oral health conditions. Many older adults do not have dental insurance and are also likely to have some chronic conditions, which can

    High sodium intake is 1 of the modifiable risk factors for cardiovascular disease, but in Korea, daily sodium intake is estimated to be double the level recommended by World Health Organization. We investigated the association between the estimated 24-h urinary sodium excretion (24hUNaE) and metabolic syndrome using nationwide population data.In total, 17,541 individuals (weighted n = 33,200,054; weighted men, 52.5% [95% confidence interval, CI = 51.8-53.3]; weighted age, 45.2 years [44.7-45.7]) who participated in the Korean Health and Nutrition Examination Survey 2009 to 2011 were investigated. NCEP-ATP III criteria for metabolic syndrome were used, and sodium intake was estimated by 24hUNaE using Tanaka equation with a spot urine sample.The weighted mean 24hUNaE values were 3964 mg/d (95% CI = 3885-4044) in men and 4736 mg/d (4654-4817) in women. The weighted age-adjusted prevalence of metabolic syndrome was 22.2% (21.4-23.0), and it increased with 24hUNaE quartile in both men and women (mean ± standard error of the mean; men: 22.5 ± 1.0%, 23.0 ± 1.0%, 26.0 ± 1.2%, and 26.0 ± 1.2%; P = 0.026; women: 19.4 ± 0.8%, 17.7 ± 0.8%, 19.8 ± 1.0%, and 23.0 ± 1.1%; P = 0.002, for quartiles 1-4, respectively). Even after adjustment for age, daily calorie intake, heavy alcohol drinking, regular exercise, college graduation, and antihypertensive medication, the weighted prevalence of metabolic syndrome increased with the increase in 24hUNaE in men and women. The weighted 24hUNaE was positively associated with the number of metabolic syndrome components after adjustment for confounding factors in men and women. In subjects without antihypertensive medication, the odds ratio for metabolic syndrome in quartile 4 of 24hUNaE compared with quartile 1 was 1.56 (1.33-1.84, P < 0.001) in the total population, 1.66 (1.34-2.06, P < 0.001) in men, and 1.94 (1.49-2.53, P < 0.001) in women.In this nationwide

    This study examined the effect of age-stereotype threat on older adults' performance on a task measuring hazard perception performance in driving. The impact of age-stereotype threat in relation to the value participants placed on driving and pre- and post-task confidence in driving ability was also investigated. Eighty-six adults aged from 65 years of age completed a questionnaire measuring demographic information, driving experience, self-rated health, driving importance, and driving confidence. Prior to undertaking a timed hazard perception task, participants were exposed to either negative or positive age stereotypes. Results showed that age-stereotype threats, while not influencing hazard perception performance, significantly reduced post-driving confidence compared with pre-driving confidence for those in the negative prime condition. This finding builds on the literature that has found that stereotype-based influences cannot simply be understood in terms of performance outcomes alone and may be relevant to factors affected by confidence such as driving cessation decisions.

    Full Text Available Normal human thymuses at various ages were immunohistologically examined in order to determine whether adult or aged thymus maintained the microenvironment for the T cell development and thymopoiesis was really ongoing. To analyze the thymic microenvironment, two monoclonal antibodies (MoAb were employed. One is MoAb to IL-1 receptor (IL-1R recognizing medullary and subcapsular cortical epithelial cells of normal infant human thymus. The other is UH-1 MoAb recognizing thymic epithelial cells within the cortex, which are negative with IL-1R-MoAb. Thymus of subjects over 20 years of age was split into many fragments and dispersed in the fatty tissue. However, the microenvironment of each fragment was composed of both IL-1R positive and UH-1 positive epithelial cells, and the UH-1 positive portion was populated with lymphocytes showing a follicle-like appearance. Lymphocytes in these follicle-like portions were mostly CD4+CD8+ double positive cells and contained many proliferating cells as well as apoptotic cells. Thus these follicle-like portions in adult and aged thymus were considered to be functioning as cortex as in infant thymus. Proliferative activity of thymocytes in the thymic cortex and the follicle-like portions definitely declined with advance of age, while incidence of apoptotic thymocytes increased with aging.

  16. Effects of Aging and Adult-Onset Hearing Loss on Cortical Auditory Regions

    Science.gov (United States)

    Cardin, Velia

    2016-01-01

    Hearing loss is a common feature in human aging. It has been argued that dysfunctions in central processing are important contributing factors to hearing loss during older age. Aging also has well documented consequences for neural structure and function, but it is not clear how these effects interact with those that arise as a consequence of hearing loss. This paper reviews the effects of aging and adult-onset hearing loss in the structure and function of cortical auditory regions. The evidence reviewed suggests that aging and hearing loss result in atrophy of cortical auditory regions and stronger engagement of networks involved in the detection of salient events, adaptive control and re-allocation of attention. These cortical mechanisms are engaged during listening in effortful conditions in normal hearing individuals. Therefore, as a consequence of aging and hearing loss, all listening becomes effortful and cognitive load is constantly high, reducing the amount of available cognitive resources. This constant effortful listening and reduced cognitive spare capacity could be what accelerates cognitive decline in older adults with hearing loss. PMID:27242405

  17. Evaluation of effective dose conversion coefficients for Korean adults during medical x-ray examinations up to 150 keV through comparison with ICRP Publication 74 and ICRP Publication 116

    International Nuclear Information System (INIS)

    A Monte Carlo program for calculating organ doses for patients undergoing medical x-ray examination (PCXMC) was used to calculate effective dose conversion coefficients for Korean adults. Two sets of effective dose results were calculated based on tissue weighting factors recommended in International Commission on Radiological Protection (ICRP) Publications 60 and 103 for monochromatic energy photons of 10, 15, 20, 30, 40, 50, 60, 70, 80, 100 and 150 keV. The results were obtained for monoenergetic photons, since effective dose conversion coefficients recommended in ICRP Publications 74 and 116 were given for monochromatic energies, thereby enabling the comparison of our result to those suggested by the ICRP publications. The areas of comparison include: to observe effects due to changes in tissue weighting factors, modification within Medical Internal Radiation Dose (MIRD) phantoms and differences in phantom types. The phantom employed in the PCXMC program is a modified version of the phantom used in ICRP Publication 74, with additional organs that were added in order to take into account the updated tissue weighting factors given in ICRP Publication 103. Both use MIRD phantoms but our study modified the phantom size to the average physical condition of Korean adults, while ICRP Publication 74 uses the phantom size of the reference man defined in ICRP Publication 23. On the other hand, the effective dose suggested in ICRP 116 was calculated using an entirely different type of phantom: a voxel phantom with the size of reference man. Although significant differences were observed for certain organ doses in the lateral beam directions, differences in the effective doses were within 5% for the anterior–posterior (AP) and posterior–anterior (PA) directions, and within 16% in lateral directions when tissue weighting factors were applied and the variations were adjusted for all three comparisons. The results show that calculation of effective doses for Korean adults

    2016-01-01

    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, χ2=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. PMID:26770046

    Aging is associated with microstructural changes in brain tissue that can be visualized using diffusion tensor imaging (DTI). While previous studies have established age-related changes in white matter (WM) diffusion using DTI, the impact of age on gray matter (GM) diffusion remains unclear. The present study utilized DTI metrics of mean diffusivity (MD) to identify age differences in GM/WM microstructure in a sample of healthy older adults (N = 60). A secondary aim was to determine the functional significance of whole-brain GM/WM MD on global cognitive function using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). Participants were divided into three age brackets (ages 50-59, 60-69, and 70+) to examine differences in MD and cognition by decade. MD was examined bilaterally in the frontal, temporal, parietal, and occipital lobes for the primary analyses and an aggregate measure of whole-brain MD was used to test relationships with cognition. Significantly higher MD was observed in bilateral GM of the temporal and parietal lobes, and in right hemisphere WM of the frontal and temporal lobes of older individuals. The most robust differences in MD were between the 50-59 and 70+ age groups. Higher whole-brain GM MD was associated with poorer RBANS performance in the 60-69 age group. Results suggest that aging has a significant and differential impact on GM/WM diffusion in healthy older adults, which may explain a modest degree of cognitive variability at specific time points during older adulthood.

    Full Text Available High sodium intake is associated with the development of chronic diseases such as obesity. Although its role in obesity remains controversial, there may be a correlation between salt sensitivity and the early onset of chronic diseases in obese children.In all, 2,163 Korean children (1,106 boys and 1,057 girls aged 8-9 years were recruited from seven elementary schools in Seoul. To evaluate whether obesity risk was modulated by the salt sensitivity, 11 SNPs related to salt sensitive genes (SSG became the target of sodium intakes in obese children.BP, HOMA-IR, LDLc, TG, and the girls' sodium intake significantly increased, but HDLc significantly decreased with increase in BMI. Regardless of sex, the obesity risk was 5.27-fold (CI; 1.320-27.560 higher in the Q2 to Q5 of sodium intake adjusted by energy (4044.9-5058.9 mg/day than in the lowest Q1 level (2287.6 mg/day in obese children. BP was sensitively dependent on insulin resistance and lipid accumulation in all subjects; however, sodium intake may be an independent risk factor of obesity without increasing BP in girls. GRK4 A486V mutant homozygote was highly distributed in the obese group, but other SNPs had no impact. The obesity risk increased 7.06, 16.8, and 46.09-fold more in boys with GRK4 A486V, ACE, and SLC12A3 mutants as sodium intake increased. Among girls, the obesity risk increased in GRK4 A486V heterozygote and CYP11β-2 mutant homozygote although sodium intake was relatively lower, implying that ACE, SLC12A, CYP11β-2, and GRK4 A486V polymorphisms showed gender-based differences with regard to interaction between sodium intake and obesity.A high sodium intake markedly increased the obesity risk in variants of GRK4 A486V regardless of sex. The obesity risk increased with GRK4 A486V, ACE, and SLC12A3 variants in boys, whereas it increased with GRK4 A486V and CYP11B2 variants in girls as sodium intake increased. Obese children with the specific gene variants are recommended to reduce

    Patients with treated HIV-1-infection experience earlier occurrence of aging-associated diseases, raising speculation that HIV-1-infection, or antiretroviral treatment, may accelerate aging. We recently described an age-related co-methylation module comprised of hundreds of CpGs; however, it is unknown whether aging and HIV-1-infection exert negative health effects through similar, or disparate, mechanisms. We investigated whether HIV-1-infection would induce age-associated methylation changes. We evaluated DNA methylation levels at >450,000 CpG sites in peripheral blood mononuclear cells (PBMC) of young (20-35) and older (36-56) adults in two separate groups of participants. Each age group for each data set consisted of 12 HIV-1-infected and 12 age-matched HIV-1-uninfected samples for a total of 96 samples. The effects of age and HIV-1 infection on methylation at each CpG revealed a strong correlation of 0.49, pnetwork analysis (WGCNA) identified 17 co-methylation modules; module 3 (ME3) was significantly correlated with age (cor=0.70) and HIV-1 status (cor=0.31). Older HIV-1+ individuals had a greater number of hypermethylated CpGs across ME3 (p=0.015). In a multivariate model, ME3 was significantly associated with age and HIV status (Data set 1: βage=0.007088, p=2.08 x 10(-9); βHIV=0.099574, p=0.0011; Data set 2: βage=0.008762, p=1.27 x 10(-5); βHIV=0.128649, p=0.0001). Using this model, we estimate that HIV-1 infection accelerates age-related methylation by approximately 13.7 years in data set 1 and 14.7 years in data set 2. The genes related to CpGs in ME3 are enriched for polycomb group target genes known to be involved in cell renewal and aging. The overlap between ME3 and an aging methylation module found in solid tissues is also highly significant (Fisher-exact p=5.6 x 10(-6), odds ratio=1.91). These data demonstrate that HIV-1 infection is associated with methylation patterns that are similar to age-associated patterns and suggest that general aging

    Although serum cholesterol has been associated with late-life depression, few studies on the associations between lipids and depression among middle-aged adults have been performed. This study examined associations between serum lipid levels and depressive symptoms in Korean middle-aged adults. We used data from 8207 participants aged 40-64 years who completed a questionnaire about their experience of depressive symptoms over the last year as part of the 2010-2012 Korean National Health and Nutrition Examination Survey. Higher HDL-C levels were significantly associated with an elevated risk of depressive symptoms (OR=1.32; 95% CI=1.09-1.60) after adjusting for other covariates. PMID:27179182

    Full Text Available Autism spectrum disorders (ASDs are neurodevelopmental disorders characterised by impaired social interaction and communication, and restricted behaviour and interests. A disruption in the balance of excitatory and inhibitory neurotransmission has been hypothesised to underlie these disorders. Here we demonstrate that genes of both pathways are affected by ASD, and that gene expression of inhibitory and excitatory genes is altered in the cerebral cortex of adult but not younger autistic individuals. We have developed a measure for the difference in the level of excitation and inhibition based on gene expression and observe that in this measure inhibition is decreased relative to excitation in adult ASD compared to control. This difference was undetectable in young autistic brains. Given that many psychiatric features of autism are already present at an early age, this suggests that the observed imbalance in gene expression is an ageing phenomenon in ASD rather than its underlying cause.

  6. Adult hippocampal neurogenesis inversely correlates with microglia in conditions of voluntary running and aging.

    Full Text Available Adult hippocampal neurogenesis results in the formation of new neurons and is a process of brain plasticity involved in learning and memory. The proliferation of adult neural stem or progenitor cells is regulated by several extrinsic factors such as experience, disease or aging and intrinsic factors originating from the neurogenic niche. Microglia is very abundant in the dentate gyrus and increasing evidence indicates that these cells mediate the inflammation-induced reduction in neurogenesis. However, the role of microglia in neurogenesis in physiological conditions remains poorly understood. In this study, we monitored microglia and the proliferation of adult hippocampal stem/progenitor cells in physiological conditions known to increase or decrease adult neurogenesis, voluntary running and aging respectively. We found that the number of microglia in the dentate gyrus was strongly inversely correlated with the number of stem/progenitor cells and cell proliferation in the granule cell layer. Accordingly, co-cultures of decreasing neural progenitor/glia ratio showed that microglia but not astroglia reduced the number of progenitor cells. Together, these results suggest that microglia inhibits the proliferation of neural stem/progenitor cells despite the absence of inflammatory stimulus.

    Healthy aging can lead to impairments in learning that affect many laboratory and real-life tasks. These tasks often involve the acquisition of dynamic contingencies, which requires adjusting the rate of learning to environmental statistics. For example, learning rate should increase when expectations are uncertain (uncertainty), outcomes are surprising (surprise) or contingencies are more likely to change (hazard rate). In this study, we combine computational modelling with an age-comparative behavioural study to test whether age-related learning deficits emerge from a failure to optimize learning according to the three factors mentioned above. Our results suggest that learning deficits observed in healthy older adults are driven by a diminished capacity to represent and use uncertainty to guide learning. These findings provide insight into age-related cognitive changes and demonstrate how learning deficits can emerge from a failure to accurately assess how much should be learned. PMID:27282467

    Full Text Available BACKGROUND: Microalbuminuria is associated with increased risk of renal disease and cardiovascular diseases even in non-diabetic subjects. High incidence rates of microalbuminuria have been found in a number of population-based studies. However, the prevalence and risk factors associated with microalbuminuria in the general population in Korea are unclear. OBJECTIVES: The present study was performed to estimate the prevalence of microalbuminuria and investigate the associated risk factors in the general adult population using the Fifth Korea National Health and Nutrition Examination Survey (KNHANES V-2 data from 2011. METHODS: A total of 5,202 participants (mean age, 45.6 years; men, 2,337; women, 2,865 were included in the analysis. Microalbuminuria was evaluated in participants of KNHANES V-2 based on the urine albumin-creatinine ratio. Estimated glomerular filtration rate was calculated using the Modification of Diet in Renal Disease study equation. RESULTS: The weighted prevalence of microalbuminuria was 5.2% (95% CI, 4.4-6.1 in the general population. The prevalence of albuminuria is increased with age. After adjustment for age and sex, the presence of albuminuria was associated with increased waist circumference, systolic and diastolic blood pressure, aspartate aminotransferase, triglyceride, fasting plasma glucose, and the presence of hypertension and diabetes. In logistic regression analyses, older age, female sex, diabetes, hypertension, and serum aspartate aminotransferase were independently associated with the presence of albuminuria. CONCLUSION: The prevalence of microalbuminuria was found to be 5.2%, and conventional risk factors for cardiovascular diseases are closely related to the presence of microalbuminuria in Korea. Microalbuminuria may be a useful marker to identify individuals with increased risk of cardiovascular disease.

Little is known about active aging in older Thai adults, and there has been no development of scales to measure the expression of active aging attributes. Purpose: The aim of this study was to develop a culturally relevant composite scale of active aging for Thai adults (AAS-Thai and to evaluate its reliability and validity. Methods: Eight steps of scale development were followed: 1 using focus groups and in-depth interviews, 2 gathering input from existing studies, 3 developing preliminary quantitative measures, 4 reviewing for content validity by an expert panel, 5 conducting cognitive interviews, 6 pilot testing, 7 performing a nationwide survey, and 8 testing psychometric properties. In a nationwide survey, 500 subjects were randomly recruited using a stratified sampling technique. Statistical analyses included exploratory factor analysis, item analysis, and measures of internal consistency, concurrent validity, and test–retest reliability. Results: Principal component factor analysis with varimax rotation resulted in a final 36-item scale consisting of seven factors of active aging: 1 being self-reliant, 2 being actively engaged with society, 3 developing spiritual wisdom, 4 building up financial security, 5 maintaining a healthy lifestyle, 6 engaging in active learning, and 7 strengthening family ties to ensure care in later life. These factors explained 69% of the total variance. Cronbach’s alpha coefficient for the overall AAS-Thai was 0.95 and varied between 0.81 and 0.91 for the seven subscales

    Full Text Available Understanding the post-treatment physical and mental function of older adults from ethnic/racial minority backgrounds with cancer is a critical step to determine the services required to serve this growing population. The double jeopardy hypothesis suggests being a minority and old could have compounding effects on health. This population-based study examined the physical and mental function of older adults by age (mean age = 75.7, SD = 6.1, ethnicity/race, and cancer (breast, prostate, colorectal, and gynecologic as well as interaction effects between age, ethnicity/race and HRQOL. There was evidence of a significant age by ethnicity/race interaction in physical function for breast, prostate and all sites combined, but the interaction became non-significant (for breast and all sites combined when comorbidity was entered into the model. The interaction persisted in the prostate cancer group after controlling for comorbidity, such that African Americans and Asian Americans in the 75–79 age group report lower physical health than non-Hispanic Whites and Hispanic Whites in this age group. The presence of double jeopardy in the breast and all sites combined group can be explained by a differential comorbid burden among the older (75–79 minority group, but the interaction found in prostate cancer survivors does not reflect this differential comorbid burden.

  2. Age-related changes in normal adult pancreas: MR imaging evaluation

    International Nuclear Information System (INIS)

    Objective: To investigate age-related changes in normal adult pancreas as identified by magnetic resonance imaging (MRI). Materials and methods: We examined 115 patients without pancreatic diseases (21–90 years) who underwent upper abdominal MRI to evaluate the normal pancreatic MRI findings related to aging. The parameters examined were the pancreatic anteroposterior (AP) diameter, pancreatic lobulation, pancreatic signal intensity (SI), depiction of the main pancreatic duct (MPD), grade of the visual SI decrease on the opposed-phase T1-weighted images compared with in-phase images, and enhancement effect of the pancreas in the arterial phase of dynamic imaging. Results: The pancreatic AP diameter significantly reduced (head, p = 0.0172; body, p = 0.0007; tail, p < 0.0001), and lobulation (p < 0.0001) and parenchymal fatty change (p < 0.0001) became more evident with aging. No significant correlation was observed between aging and pancreatic SI, however the SI on the in-phase T1-weighted images tended to decrease with aging. No significant correlation was observed between aging and the depiction of the MPD as well as aging and contrast enhancement. Conclusion: MRI findings of pancreatic atrophy, lobulation, and fatty degeneration are characteristic changes related to aging, and it is necessary to recognize these changes in the interpretation of abdominal MRI in patients with and without pancreatic disease

    Full Text Available Intertemporal choices are a ubiquitous class of decisions that involve selecting between outcomes available at different times in the future. We investigated the neural systems supporting intertemporal decisions in healthy younger and older adults. Using functional neuroimaging, we find that aging is associated with a shift in the brain areas that respond to delayed rewards. Although we replicate findings that brain regions associated with the mesolimbic dopamine system respond preferentially to immediate rewards, we find a separate region in the ventral striatum with very modest time dependence in older adults. Activation in this striatal region was relatively insensitive to delay in older but not younger adults. Since the dopamine system is believed to support associative learning about future rewards over time, our observed transfer of function may be due to greater experience with delayed rewards as people age. Identifying differences in the neural systems underlying these decisions may contribute to a more comprehensive model of age-related change in intertemporal choice.

Social relationships included social contact, living arrangements and marital status. Both childhood and adult socio-economic factors were independently associated with diet quality. Compared with non-manual social class, men of childhood manual social class were less likely to consume fruit and vegetables daily (OR 0.80, 95% CI 0.66, 0.97), as were men of adult manual social class (OR 0.65, 95% CI 0.54, 0.79), and less likely to be in the top EDI quartile (OR 0.73, 95% CI 0.61, 0.88), similar to men of adult manual social class (OR 0.66, 95 % CI 0.55, 0.79). Diet quality decreased with increasing adverse adult socio-economic scores; however, the association with adverse childhood socio-economic scores diminished with adult social class adjustment. A combined adverse childhood and adulthood socio-economic score was associated with poor diet quality. Diet quality was most favourable in married men and those not living alone, but was not associated with social contact. Diet quality in older men is influenced by childhood and adulthood socio-economic factors, marital status and living arrangements. PMID:25827289

    Previous studies of dual-task performance have demonstrated that encoding and retrieval processes are differentially affected by the simultaneous performance of a secondary task. Whilst dual task demands during encoding have a detrimental effect on memory performance, dual task demands during retrieval have a detrimental effect on secondary task performance. However, dual task effects on memory during encoding appear unaffected by age, while effects at retrieval on secondary task performance are age sensitive. Most previous studies have focused on free recall or cued recall of word lists. In the current study, encoding and retrieval were examined in younger and older healthy adults performing a task typically thought to load verbal working memory, namely immediate serial ordered digit recall together with a response time (RT) task. In Experiment 1, the demands of a secondary RT task were varied as a function of response-to-stimulus interval, while in Experiment 2 the predictability of the stimulus location was manipulated. In both age groups, dual task during encoding, but not at retrieval, produced significant interference in memory performance and unlike most previous studies the impact at encoding was greater for the older group. In contrast, significantly slower RTs were demonstrated under dual task conditions during encoding and retrieval. Older adults produced significantly slower RTs than younger adults only for dual task at retrieval. Older people were more sensitive to time pressure in responding under dual task conditions, but neither group was sensitive to predictability of stimulus location. Results are consistent with the concept of a cognitive resource that supports dual task performance, and that is sensitive to the effects of age on memory encoding of items that rely heavily on the operation of verbal working memory resources. The age sensitivity to dual task only became apparent when effects at encoding and at retrieval were considered separately

    The immune system becomes less effective with age, and older age is associated with an increased susceptibility to diseases and reduced responses to vaccination. Furthermore, some adult populations, such as those with diabetes mellitus, are at increased risk of acute hepatitis B virus (HBV) infection. Decreasing responses to vaccination with advanced age have been described, but it is not known at what age immunogenicity starts to reduce, or until what age immunogenicity remains acceptable (f...

  10. A Study of the Internal and External Morphology in the Mandibular first Premolar of the Middle-Aged Korean Using a Microcomputed Tomography

    International Nuclear Information System (INIS)

    Dental statistics for Koreans are far from complete and the majority of previous researches have adopted techniques such as radiological analysis and sectioning of teeth for morphological information, which are time-consuming, less accurate and destructive. Thus, a new nondestructive method is necessary to get precise dental standardization data for Koreans. For the above purpose, each of the first premolars was scanned by a micro-CT (SkyScan, Belgium) with a resolution of 21.31 μm at an interval of 0.022mm along the plane horizontally parallel to an occlusion plane. Internal and external morphological sections were measured and compared to the values in the average tooth size table for permanent teeth presented by G. V Black

    Full Text Available Introduction. In the last decades, life expectancy of persons with Down syndrome (DS has dramatically increased and it is estimated that they will be living as long as the general population within a generation. Despite being included among the progeroid syndromes, because of the presence of features typically observed in older adults, DS is still regarded as a disease of pediatric interest. Because limited knowledge is available on the clinical characteristics of adults with DS, this study aimed to assess clinical and non-clinical features of this population and to describe similarities to the geriatric population. Methods. In this study, we described 60 adults with DS evaluated at the Day Hospital of the Geriatric Department of the Policlinico A. Gemelli, Università Cattolica del Sacro Cuore in Rome. Individuals were assessed through a standardized protocol. Results. The mean age of study participants was 38 years (range, 18 to 58 years and 42 (70.0% were women. Geriatric conditions were highly prevalent: severe cognitive impairment was diagnosed in 39 (65.0% participants, behavioral symptoms were present in 25 (41.7% and functional impairment in 23 (38.3%. Six (10.0% participants lived in institutions and 11 (18.3% were diagnosed as obese. The mean number of drugs used was 2.4; use of psychotropic drugs was highly prevalent. The most common chronic diseases were thyroid problems (44, 73.3%, followed by mood disorders (19, 31.7%, osteoporosis (18, 30.0% and cardiac problems (10, 16.7%. Geriatric conditions and chronic diseases were more prevalent among participants aged ≥40 years. Conclusions. Several similarities between older adults and adults with DS were observed. Comorbidities, geriatric conditions, cognitive and functional deficits and social problems are highly prevalent in both populations, contributing to the high complexity of these patients’ assessment and treatment.

    Older adults are more likely than younger adults to experience stress when confronted with cognitive challenges. However, little is known about individual differences that might explain why some older adults exhibit stronger stress responses than others. We examined the interplay of two social-cognitive factors to explain older adults' cortisol reactivity: (1) subjective social status, and (2) essentialist beliefs about cognitive aging. We hypothesized that, depending on whether older adults believe that aging-related cognitive decline is inevitable versus modifiable, low subjective social status should lead to stronger or weaker cortisol reactivity. Using longitudinal data, we assessed the impact of cognitive challenges on stress reactivity in a sample of older adults (N = 389; 61-86 years). As predicted, regression analyses confirmed that 44 min after cognitively challenging tasks, older adults exhibited a significantly different cortisol reactivity depending on their subjective social status and their essentialist beliefs about cognitive aging. Specifically, older adults with low subjective social status and high essentialist beliefs showed a significantly elevated cortisol reactivity. We discuss the role of essentialist beliefs about cognitive aging to predict when and why high versus low subjective social status leads to stress responses in older adults. PMID:27159187

    Basic data on the resting energy expenditure (REE) of healthy populations are currently rare, especially for developing countries. The aims of the present study were to describe gender- and age-specific REE distributions and to evaluate the relationships among glycolipid metabolism, eating behaviors, and REE in healthy Chinese adults. This cross-sectional survey included 540 subjects (343 women and 197 men, 20-79 years old). REE was measured by indirect calorimetry and expressed as kcal/day/kg total body weight. The data were presented as the means and percentiles for REE and the REE to fat-free mass (FFM) ratio; differences were described by gender and age. Partial correlation analysis was used to analyze the correlations between REE, tertiles of REE/FFM, and glycolipid metabolism and eating behaviors. In this study, we confirmed a decline in REE with age in women (p = 0.000) and men (p = 0.000), and we found that men have a higher REE (p = 0.000) and lower REE/FFM (p = 0.021) than women. Furthermore, we observed no associations among glycolipid metabolism, eating behaviors, and REE in healthy Chinese adults. In conclusion, the results presented here may be useful to clinicians and nutritionists for comparing healthy and ill subjects and identifying changes in REE that are related to aging, malnutrition, and chronic diseases.

    Appropriate neuromuscular responses to support surface perturbations are crucial to prevent falls, but aging-related anatomical and physiological changes affect the appropriateness and efficiency of such responses. Low-level noise application to sensory receptors has shown to be effective for postural improvement in a variety of different balance tasks, but it is unknown whether this intervention may have value for improvement of corrective postural responses. Ten healthy younger and ten healthy older adults were exposed to sudden backward translations of the support surface. Low-level noise (mechanical vibration) to the foot soles was added during random trials and temporal (response latency) and spatial characteristics (maximum center-of-pressure excursion and anterior-posterior path length) of postural responses were assessed. Mixed-model ANOVA was applied for analysis of postural response differences based on age and vibration condition. Age affected postural response characteristics, but older adults were well able to maintain balance when exposed to a postural perturbation. Low-level noise application did not affect any postural outcomes. Healthy aging affects some specific measures of postural stability, and in high-functioning older individuals, a low-level noise intervention may not be valuable. More research is needed to investigate if recurring fallers and neuropathy patients could benefit from the intervention in postural perturbation tasks. PMID:27195007

    American music has been found to relieve pain in adults in several countries but has not been tested in Korea. Korean women have reported that they would like American music as well as Korean folk songs and religious music sung in Korean. The study purpose was to pilot-test the effects of music on pain after gynecologic surgery in Korean women and to compare pain relief between those who chose American or Korean music. Using a quasiexperimental pretest-posttest design, 73 South Korean women on a preoperative unit were assigned by day of the week to receive music (n = 34; 47%) or no music (n = 39; 53%). The music group chose among Korean (ballads and religious and popular songs) and American (soft slow piano and orchestra) music and heard it for 15 minutes at four time points (postoperatively), whereas the controls rested in bed. They marked VAS Sensation and Distress of Pain scales before and after each test. The two groups were similar on pretest pain. When controlling for pretest pain, MANCOVA indicated that there was significantly less posttest pain in those with music plus analgesics than those with analgesics alone at three of the four tests: p = .04 to .001. Two-thirds in the music group (n = 21; 62%) chose Korean music and one-third (n = 13; 38%) chose American, with no difference in pain: both were effective. In addition to analgesics, music can be used to reduce postoperative pain in Korean women. Patients selected music that was appealing to them. Nurses in many countries can consider music of the country and seek individual preferences to use in addition to analgesics for postoperative pain. PMID:18706380

  17. The Relationship of Age, Body Mass Index, and Individual Habit to Bone Mineral Density in Adults

    International Nuclear Information System (INIS)

    We studied the change of bone mineral density (BMD) by age, body mass index (BMI), coffee, carbonated drink, alcohol, smoking, and exercise in adults who checked in health center. The number of study subjects was total 268 persons (women of 136 persons and men of 132 persons). The BMD was determined in lumbar spine and femoral neck by dual energy x-ray absorptiometry. And we got some results as below : 1. In women, mean body height was , mean body weight was 155.8±6.0 cm, and mean BMI was 56.8±7.9 kg. In men, mean body height was 169.1±6.0 cm, mean body weight was 69.0±9.5 kg, and mean BMI was 24.1±2.7 kg/m2. 2. BMD decreased as age increased, and the age was the most determinant factor for BMD (p<0.01). Women's BMD decreased rapidly in the groups aged ≥50s, while men's BMD decreased gradually with age. In addition, for both sex, lower BMD was measured in lumbar spine than in femoral neck. 3. BMD increased in high BMI, and BMD with BMI increased distinctly in the group aged 50s. But their relationship was not significant. 4. In view of the distribution by three BMD categories, women's BMD was mostly normal in the groups aged ≥40s but the rate of osteopenia and osteoporosis was similar in the group aged 50s, and the rate of osteoporosis was the highest in the groups aged 60s and 70s. Men's BMD was mostly normal through all groups except the group aged 70s. 5. Coffee and carbonated drink were not influenced in BMD. But alcohol-drinking group showed higher BMD than non-drinking group, and alcohol was statistically significant determinant for BMD (p<0.05). Smoking and exercise were not statistically significant determinant of BMD.

    Functional magnetic resonance imaging (fMRI) research conducted in healthy young adults is typically done with the assumption that this sample is largely homogeneous. However, studies from cognitive psychology suggest that long-term memory and attentional control begin to diminish in the third decade of life. Here, 100 participants between the ages of 18 and 31 learned Lithuanian translations of English words in an individual differences study using fMRI. Long-term memory ability was operationalized for each participant by deriving a memory score from 3 convergent measures. Age of participant predicted memory score in this cohort. In addition, degree of deactivation during initial encoding in a set of regions occurring largely in the default mode network (DMN) predicted both age and memory score. The current study demonstrates that early memory decline may partially be accounted for by failure to modulate activity in the DMN. PMID:26209847

    The aim of this study was to investigate the effect of flooring on barefoot gait according to age and gender. Two groups of healthy subjects were analyzed: the elderly adult group (EA; 10 healthy subjects) and the middle-aged group (MA; 10 healthy subjects). Each participant was asked to walk at his or her preferred speed over two force plates on the following surfaces: 1) homogeneous vinyl (HOV), 2) carpet, 3) heterogeneous vinyl (HTV) and 4) mixed (in which the first half of the pathway was covered by HOV and the second by HTV). Two force plates (Kistler 9286BA) embedded in the data collection room floor measured the ground reaction forces and friction. The required coefficient of friction (RCOF) was analyzed. For the statistical analysis, a linear mixed-effects model for repeated measures was performed. During barefoot gait, there were differences in the RCOF among the flooring types during the heel contact and toe-off phases. Due to better plantar proprioception during barefoot gait, the EA and MA subjects were able to distinguish differences among the flooring types. Moreover, when the EA were compared with the MA subjects, differences could be observed in the RCOF during the toe-off phase, and gender differences in the RCOF could also be observed during the heel contact phase in barefoot gait.

    The purpose of this study was to investigate the influence of work environments and occupational hazards on smoking intensity by occupation type in Korean workers. This study used the data from the Fourth Korea National Health and Nutrition Examination Survey in 2009. The sample of this study included 3,769 adults who were aged 18 years or older and had an occupation of office work, sales, or manufacturing. After controlling for sociodemographic characteristics, the generalized linear models revealed that office workers and the sales force who had smoking co-workers at the workplace were more likely to smoke than those who did not. A dirty workplace and exposure to occupational noise were significant factors increasing the smoking intensity for manufacturers. A smoking cessation program considering physical work environments and co-workers' support should be developed for Korean workers. PMID:26681605

    The objective of the present work is to assess the current breakfast model in different age groups: children between the ages of 6 and 12 years (n = 54); adolescents between the ages of 13 and 17 years (n = 174); and adults, older than 18 years of age (n = 252). For this a questionnaire has been designed that follows the standards of that used for a similar study by our team in 1984 on a sample of 1350 individuals. The modified and amplified questionnaire included open and closed questions about: the omission of breakfast and its causes, foods that are a part of breakfast, the most frequent types and the variations, the role of the second breakfast, the number of fasting hours since dinner, the time spent of breakfast, and the subjective opinion regarding the importance or not of having breakfast. 98.95% answer yes to the question do you have breakfast, but only 9% eats a nutritionally correct breakfast, one defined as that breakfast that supplies 20% of the total energy and includes foods from at least four different groups. All the children included some form of milk product in their breakfast. The adolescents consumed the lowest proportion of cereals (19.4%) and the highest proportion of pastries (24.2%). The percentage of adults who drink coffee with milk (57%) and sugar (37.7%) is significantly higher than that it the other two groups. Bread (37.7%), pastries (28.3%) and cookies (26.1%) are the solid foods eaten most by the adults. The children spend the longest time on breakfast. 35.9% of the sample varies their breakfast, 43.1% never does, and 21% does so sometimes. The average time elapsed between dinner and breakfast is 10.5 +/- 1.2 hours. It is advisable to have a more nutritionally balanced breakfast, including different foods from at least four groups, and including a greater variety in the menus. PMID:9780752

    Shepherd, Alison

    The UK has an ageing population, but this is not being matched by a similar increase in healthy life expectancy. The greatest challenge in the 21st century will be to improve the quality of life as ageing occurs. Health is the most important prerequisite for people to enjoy life in their older years (Brundtland, 1988). Diet is one factor that is believed to play a key role in the prevention and treatment of chronic diseases associated with ageing. The third and final part of this series addressing the concept of nutrition through the lifespan seeks to educate health-care professionals as to what constitutes a healthy diet for the elderly population, and gives practical guidance as to how to try and prevent the ever-growing problem of malnutrition within this age group. It is suggested that when the older adult is hospitalized their risk of malnutrition increases. Therefore, some guidance for the use of oral nutritional supplements in this population is given. Good nutrition and physical exercise are essential for healthy ageing from both a physical and psychological perspective (NICE, 2008). Therefore a multidisciplinary life course approach to ageing is vital to minimizing its complications for quality of life and subsequent public health (Denny, 2008). PMID:19273990

    Inhibitory control can be investigated with the countermanding task, which requires subjects to make a response to a go signal and cancel that response when a stop signal is presented occasionally. Adult humans performing the countermanding task typically exhibit impaired response time (RT), stop signal response time (SSRT) and response accuracy as they get older, but little change in post-error slowing. Rodent models of the countermanding paradigm have been developed recently, yet none have directly examined age-related changes in performance throughout the lifespan. Male Wistar rats (N = 16) were trained to respond to a visual stimulus (go signal) by pressing a lever directly below an illuminated light for food reward, but to countermand the lever press subsequent to a tone (stop signal) that was presented occasionally (25% of trials) at a variable delay. Subjects were tested in 1 h sessions at approximately 7 and 12 months of age with intermittent training in between. Rats demonstrated longer go trial RT, a higher proportion of go trial errors and performed less total trials at 12, compared to 7 months of age. Consistent SSRT and post-error slowing were observed for rats at both ages. These results suggest that the countermanding performance of rats does vary throughout the lifespan, in a manner similar to humans, suggesting that rodents may provide a suitable model for behavioral impairment related to normal aging. These findings also highlight the importance of indicating the age at which rodents are tested in countermanding investigations. PMID:27555818

    2010-01-01

    Full Text Available Introduction: It is a well-known fact that the assessment of the dental development can be related to an individual′s age, but after the age of 21 years when the wisdom teeth also complete their development, there arises a need for an optimal age estimation procedure. With advancing age, there is a reduction in the size of the pulp due to secondary dentin deposition and a measurement of this reduction can also be used as a parameter to assess the age of the individuals, both in the living and dead. Aims and Objectives: The purpose of the present study was to evaluate the feasibility of this approach in the estimation of age of adults, using Kvaal′s method in the set sample. Materials and Methods: The material consisted of the digital long-cone intraoral periapical radiographs from 50 subjects of either sex in the age group of 15-60 years, who were selected after evaluation for the set inclusion and exclusion criteria. The pulp width and length from radiographs of 6 selected teeth, namely, maxillary central incisor, lateral incisor, and second premolar and mandibular lateral incisor, canine, and first premolar of either right or left side were measured using the RVG trophy software [Trophy® Windows is a software program supplied by Trophy Radiologie (Trophy Windows Version 5.03, Copyright 1993-2002,Trophy RVG patented by Trophy, Chicago]. In order to compensate for the differences in magnification and angulation, various ratios were calculated and the mean of all ratios (M was taken as the first predictor, while the difference between the mean of 2 width ratios and the mean of 2 length ratios (W − L was taken as the second predictor. Different regression formulae for all 6 teeth, 3 maxillary teeth, 3 mandibular teeth, and each of the individual teeth were derived and the age was assessed. The assessed age was then co-related with the actual age of the patient using the Student′s t test. Results: The results showed that the coefficient of

    The purpose of this study was to examine the effect of participation in a music-based intergenerational music program on cross-age interactions and cross-age attitudes of elementary-age children and older adults, and older adults' psychosocial well-being. Twenty-one children in the 4th grade volunteered to participate in the experimental (n = 12) or control (n = 9) group. Twenty-six older adults from a retirement living facility also volunteered to participate in the experimental (n = 14) or control (n = 12) group. Ten 30-min music sessions occurred in which participants engaged in singing, structured conversation, moving to music, and instrument playing interventions. Data analysis of cross-age interactions revealed that the interventions "structured conversation" and "moving to music" were more effective in eliciting interaction behaviors than the interventions "singing" and "instrument playing." Standardized measures revealed that children's attitudes towards older adults improved, though not significantly so, after participation in the intergenerational program. Results of biweekly post-session questionnaires revealed a decrease in negative descriptions of older adults and an increase in positive descriptions of older adults--suggesting a more positive view towards aging. Results revealed that older adults' attitudes towards children improved significantly after their participation in the intergenerational program. While standardized measures revealed that older adults did not perceive a significant improvement in their psychosocial well-being, their bi-weekly post-session questionnaires showed they perceived increased feelings of usefulness and other personal benefits from the intergenerational interactions. Suggestions for future research, the utility of varied measurement instruments, and implications for practice are discussed. PMID:22506301

    Aims To explore gender differences and associations between metabolic syndrome (MetS) and its components, and diabetic retinopathy (DR) in Korean adults aged 40 years and older with diabetes. Methods We analyzed data from the Korean National Health and Nutrition Examination Surveys (2008–2012). In total, 2,576 type 2 diabetic participants, aged 40 and older, were evaluated. Seven standard retinal fundus photographs were obtained after pupil dilation in both eyes. DR was graded using the modified Airlie House classification system. Vision-threatening diabetic retinopathy (VTDR) included proliferative diabetic retinopathy and clinically significant macular edema. MetS was defined according to the Joint Interim Statement, proposed in 2009, by the International Diabetes Federation and the American Heart Association/National Heart, Lung, and Blood Institute. Multivariate logistic regression analysis was used to assess the relationship between MetS and its individual components with DR and VTDR. Results After controlling for confounders, MetS was not associated with DR in men or women. Moreover, the risk for DR or VTDR did not increase with increasing MetS components. However, high waist circumference was significantly inversely associated with VTDR (adjusted odds ratio = 0.36; 95% confidence interval = 0.14–0.93) only in men. Conclusions MetS was not associated with DR or VTDR in a Korean diabetic population. However, among MetS components, it seems that abdominal obesity was inversely associated with VTDR in Korean diabetic men. PMID:27275953

    Although psychiatric problems are less prevalent in old age within the general population, it is largely unknown whether this extends to individuals with autism spectrum disorders (ASD). We examined psychiatric symptoms and disorders in young, middle-aged, and older adults with and without ASD (Nmax = 344, age 19-79 years, IQ > 80). Albeit comparable to other psychiatric patients, levels of symptoms and psychological distress were high over the adult lifespan; 79 % met criteria for a psychiatric disorder at least once in their lives. Depression and anxiety were most common. However, older adults less often met criteria for any psychiatric diagnosis and, specifically, social phobia than younger adults. Hence, despite marked psychological distress, psychiatric problems are also less prevalent in older aged individuals with ASD. PMID:26861713

    Previous studies reported that children with cerebral palsy (CP) exhibited premature anticipatory postural adjustments (APAs) with high variability and excessive activity in the frontal plane. To better understand the effects of gross motor functioning level on APAs over the life course, the authors examined the presence and consistency of APAs in 11 adults with diplegia at 2 functioning levels against 8 age-matched healthy adults during unilateral and bilateral reaching. Results revealed an anticipatory vertical torque (TZ) and an increased likelihood of APAs during bilateral reaching for the lower functioning group. It is postulated that APAs may first emerge in TZ in CP. Results also indicated an excessive premovement postural activity in the frontal plane in both CP groups. PMID:26730748

  12. Korean initiatives on nuclear knowledge management

    International Nuclear Information System (INIS)

    Korean atomic energy activities have been the vigorous and ever expanding in the peaceful use of atomic energy. However for the last ten-year period, the new recruitments have been drastically reduced. The paper presents the nuclear manpower status in each nuclear related institute, which was surveyed in 2002. The ageing problem appears but is not very serious as a whole. The research institutes show more serious ageing problems compared to the industries. The paper also summarises the initiatives taken by Korean institutes related to the nuclear knowledge management activities with focus on the NtUss (Nuclear Technology Undergraduate Student Society) programme.

    A species-specific complex mixture of highly stable cuticular hydrocarbons (CHCs) covers the external surface of all insects. Components can be readily analyzed by gas chromatography coupled to mass spectrometry (GC-MS) to obtain a cuticular hydrocarbon profile, which may be used as an additional tool for the taxonomic differentiation of insect species and also for the determination of the age and sex of adult and immature forms. We used GC-MS to identify and quantify the CHCs of female and male Chrysomya putoria (Wiedemann, 1818) (Diptera: Calliphoridae) from one to five days old. CHCs ranged from C21 to C35 for females and from C21 to C37 in males. Major compounds were the same for both sexes and were 2-MeC28, C29:1, n-C29, 15-,13-MeC29, 2-MeC30, C31:1, n-C31 and 15-,13-MeC31. The relative abundance of each component, however, varied with age. Cluster Analysis using Bray-Curtis measure for abundance showed that cuticular hydrocarbon profiles are a strong and useful tool for the determination of age in adult C. putoria. PMID:26775199

    Full Text Available OBJECTIVE: To assess the prevalence and determinants of haematinic deficiency (lack of B12 folate or iron and macrocytosis in blood from a national population-based study of middle-aged and older adults. METHODS: A cross-sectional study involving 1,207 adults aged ≥45 years, recruited from a sub-study of the Irish National Survey of Lifestyle Attitudes and Nutrition (SLÁN 2007. Participants completed a health and lifestyle questionnaire and a standard food frequency questionnaire. Non-fasting blood samples were obtained for measurement of full blood count and expert morphological assessment, serum ferritin, soluble transferrin receptor assay (sTfR, B12, folate and coeliac antibodies. Blood samples were also assayed for thyroid function (T4, TSH, liver function, aminotransferase (AST and gamma-glutamyl transferase (GGT. RESULTS: The overall prevalence (95% C.I. of anaemia (Hb 21 nmol/ml only 2.3% were iron-deficient. 3.0% and 2.7% were found to have low levels of serum folate (99fl was detected in 8.4% of subjects. Strong, significant and independent associations with macrocytosis were observed for lower social status, current smoking status, moderate to heavy alcohol intake, elevated GGT levels, deficiency of folate and vitamin B12, hypothyroidism and coeliac disease. The population attributable fraction (PAF for macrocytosis associated with elevated GGT (25.0% and smoking (24.6% was higher than for excess alcohol intake (6.3%, folate deficiency (10.5% or vitamin B12 (3.4%. CONCLUSIONS: Haematinic deficiency and macrocytosis are common in middle-aged/older adults in Ireland. Macrocytosis is more likely to be attributable to an elevated GGT and smoking than vitamin B12 or folate deficiency.

    The concept of 'successful aging' has long intrigued the scientific community. Despite this long-standing interest, a consensus definition has proven to be a difficult task, due to the inherent challenge involved in defining such a complex, multi-dimensional phenomenon. The lack of a clear set of defining characteristics for the construct of successful aging has made comparison of findings across studies difficult and has limited advances in aging research. A consensus on markers of successful aging is furthest developed is the domain of physical functioning. For example, walking speed appears to be an excellent surrogate marker of overall health and predicts the maintenance of physical independence, a cornerstone of successful aging. The purpose of the present article is to provide an overview and discussion of specific health conditions, behavioral factors, and biological mechanisms that mark declining mobility and physical function and promising interventions to counter these effects. With life expectancy continuing to increase in the United States and developed countries throughout the world, there is an increasing public health focus on the maintenance of physical independence among all older adults.

    The evidence regarding older parental age and incidence of mood disorder symptoms in offspring is limited, and that which exists is mixed. We sought to clarify these relationships by using data from the Western Australian Pregnancy Cohort (Raine) Study. The Raine Study provided comprehensive data from 2,900 pregnancies, resulting in 2,868 live born children. A total of 1,220 participants completed the short form of the Depression Anxiety Stress Scale (DASS-21) at the 20-year cohort follow-up. We used negative binomial regression analyses with log link and with adjustment for known perinatal risk factors to examine the extent to which maternal and paternal age at childbirth predicted continuous DASS-21 index scores. In the final multivariate models, a maternal age of 30-34 years was associated with significant increases in stress DASS-21 scores in female offspring relative to female offspring of 25- to 29-year-old mothers. A maternal age of 35 years and over was associated with increased scores on all DASS-21 scales in female offspring. Our results indicate that older maternal age is associated with depression, anxiety, and stress symptoms in young adult females. Further research into the mechanisms underpinning this relationship is needed. PMID:26569038

    2001-02-01

    The aim of this paper is to highlight the contextual and psychological preconditions of parent help and helpfulness in a sample of 260 middle-aged persons belonging to two age groups, 40-45 years and 50-55 years. In a first step we want to focus on the description of the contextual situation of the persons of this "hinge generation": What are their available social networks; what are their commitments towards children and parents in terms of perceived obligation and investment; how is their perceived balance of giving and receiving; how do they anticipate and experience dependency of their parents? In a second step we will highlight the readiness of middle-aged women and men to help their parents as well as the effectively reported help. Here we are interested in the psychological determinants of such attitude and behaviour. Structural equation models are performed to estimate the predictory power of personality variables, control beliefs and reported stress (family and job) on filial helpfulness and help. Results suggest that differential aspects such as gender and age group explain a large amount of variance of the variables intergenerational commitment and satisfaction with social networks and have--along with personality variables--a strong impact on filial help and helpfulness of middle-aged adults.

    Obesity is considered a major cause of premature mortality and a potential threat to the longstanding secular decline in mortality in the United States. We measure relative and attributable risks associated with obesity among middle-aged adults using data from the Health and Retirement Study (1992–2004). Although class II/III obesity (BMI ≥ 35.0 kg/m2) increases mortality by 40% in females and 62% in males compared with normal BMI (BMI = 18.5–24.9), class I obesity (BMI = 30.0–34.9) and being...

    The ability to multitask is an incredibly important aspect of everyday life and it is thought that the cognitive processes used for multitasking are mediated by the frontal lobes (Stuss & Alexander, 2000). Patients with frontal lobe damage have been shown to be impaired in their ability to multitask, despite having normal IQ’s. It is thought that as human adult’s age, the frontal lobes deteriorate, so there is a possibility that that multitasking skills will also be impaired in older adults. ...

    Full Text Available Patients with treated HIV-1-infection experience earlier occurrence of aging-associated diseases, raising speculation that HIV-1-infection, or antiretroviral treatment, may accelerate aging. We recently described an age-related co-methylation module comprised of hundreds of CpGs; however, it is unknown whether aging and HIV-1-infection exert negative health effects through similar, or disparate, mechanisms. We investigated whether HIV-1-infection would induce age-associated methylation changes. We evaluated DNA methylation levels at >450,000 CpG sites in peripheral blood mononuclear cells (PBMC of young (20-35 and older (36-56 adults in two separate groups of participants. Each age group for each data set consisted of 12 HIV-1-infected and 12 age-matched HIV-1-uninfected samples for a total of 96 samples. The effects of age and HIV-1 infection on methylation at each CpG revealed a strong correlation of 0.49, p<1 x 10(-200 and 0.47, p<1 x 10(-200. Weighted gene correlation network analysis (WGCNA identified 17 co-methylation modules; module 3 (ME3 was significantly correlated with age (cor=0.70 and HIV-1 status (cor=0.31. Older HIV-1+ individuals had a greater number of hypermethylated CpGs across ME3 (p=0.015. In a multivariate model, ME3 was significantly associated with age and HIV status (Data set 1: βage=0.007088, p=2.08 x 10(-9; βHIV=0.099574, p=0.0011; Data set 2: βage=0.008762, p=1.27 x 10(-5; βHIV=0.128649, p=0.0001. Using this model, we estimate that HIV-1 infection accelerates age-related methylation by approximately 13.7 years in data set 1 and 14.7 years in data set 2. The genes related to CpGs in ME3 are enriched for polycomb group target genes known to be involved in cell renewal and aging. The overlap between ME3 and an aging methylation module found in solid tissues is also highly significant (Fisher-exact p=5.6 x 10(-6, odds ratio=1.91. These data demonstrate that HIV-1 infection is associated with methylation patterns that

    It is widely acknowledged that the brain anatomy of children and adolescents with autism spectrum disorder (ASD) shows a different developmental pattern then typical age-matched peers. There is however, a paucity of studies examining gray matter in mid and late adulthood in ASD. In this cross-sectional neuroimaging study, we, performed vertex-wise whole-brain and region-of-interest analyses of cortical volume, thickness, surface area, and gyrification index in 51 adults with and 49 without ASD, between 30 and 75 years. There was significant age-related volume loss and cortical thinning, but there were no group differences. The lack of significant anatomical differences between intellectual able individuals with and without ASD, suggests that ASD is not (strongly) related to gray matter morphology in mid and late adulthood.

    This paper is a summary of findings of adult age-related craniofacial morphological changes. Our aims are two-fold: (1) through a review of the literature we address the factors influencing craniofacial aging, and (2) the general ways in which a head and face age in adulthood. We present findings on environmental and innate influences on face aging, facial soft tissue age changes, and bony changes in the craniofacial and dentoalveolar skeleton. We then briefly address the relevance of this information to forensic science research and applications, such as the development of computer facial age-progression and face recognition technologies, and contributions to forensic sketch artistry.

    Lung cancer is a commonly occurring cancer among Korean American men. Korean Americans have lower rates of cancer screening participation than other Asian American sub-groups. However, little is known about factors that influence the cancer screening behavior of Korean immigrants. The purpose of this study was to explore facilitators of and barriers to lung cancer screening (i.e., low dose CT of the chest) among Korean immigrant men, using qualitative individual interviews and focus groups. A convenience sample of 24 Korean men who were immigrants, Washington State residents, able to speak Korean, aged 55-79, and eligible for lung cancer screening (based on current guidelines) were recruited from Korean churches and senior centers. Five focus groups (that included between two and five men) and nine individual interviews were conducted. Content analysis was used to analyze the qualitative data. Facilitators of lung cancer screening included perceptions about positive aspects of the health care system in South Korea, recommendations from others (physicians, family members, and community organizations), existing health problems and respiratory symptoms, interest in health, and the health consequences of aging. Barriers included costs of health care in the US, lack of time, lack of knowledge (about lung cancer and screening), attitudes about prevention, and lack of physician recommendation. This study adds new knowledge to a field where little information is available. It also lays the groundwork for developing culturally relevant lung cancer screening interventions for Korean Americans and the health care providers who serve them. PMID:26846627

    The National Health and Nutrition Examination Survey (NHANES) is a nationally representative, population-based survey designed to assess the health and nutritional status of the civilian, non-institutionalized US population. Data were collected through a personal interview regarding health history and through physical examination. Earlier NHANES surveys were conducted on a periodic basis; however, in 1999, NHANES began collecting data on a continuing, annual basis. During NHANES I, which ran from 1971-1975, audiometric testing was conducted on adults aged 25-74 years. No subsequent testing of adults was conducted in the NHANES program until 1999, when NHANES began audiometric testing of adults aged 20-69 years. This report examines the hearing levels for adults in the United States and compares them with the hearing data from NHANES I. Hearing levels are grouped by age and are grouped by ethnicity and gender.

    Cognitive performance includes the processes of attention, memory, processing speed, and executive functioning, which typically declines with aging. Previous research has demonstrated that aerobic and resistance exercise improves cognitive performance immediately following exercise. However, there is limited research examining the effect that a cognitively complex exercise such as martial art training has on these cognitive processes. Our study compared the acute effects of 2 types of martial art training to aerobic exercise on cognitive performance in middle-aged adults. We utilized a repeated measures design with the order of the 3 exercise conditions randomly assigned and counterbalanced. Ten recreational middle-aged martial artists (mean age = 53.5 ± 8.6 years) participated in 3 treatment conditions: a typical martial art class, an atypical martial art class, and a one-hour walk at a self-selected speed. Cognitive performance was assessed by the Stroop Color and Word test. While all 3 exercise conditions improved attention and processing speed, only the 2 martial art conditions improved the highest order of cognitive performance, executive function. The effect of the 2 martial art conditions on executive function was not different. The improvement in executive function may be due to the increased cortical demand required by the more complex, coordinated motor tasks of martial art exercise compared to the more repetitive actions of walking.

    A chronic disease in older adults usually runs a course that is less predictable than in younger individuals. Unexplained variations in disease incidence, prognosis, therapeutic responses, and toxicity are frequently observed among older adults. This heterogeneity poses huge challenges to the current one-size-fits-all health care systems, and calls for more personalized managements of chronic diseases in older adults. Aging is characterized by progressive deterioration of bodily functions with increasing risk of failure over time. The entire process is hierarchically organized, and progresses from intracellular events to changes at systemic and ultimately organism levels at different rates among different individuals. Aging biology exerts great influences on the development and progression of most age-related chronic diseases. Thus, aging biology could contribute to the complexity of illnesses that increase with age, and aging biomarkers possess a great potential to enable personalized health risk assessment and health care. We review evidences supporting the roles of aging biomarkers in risk assessment of prevalent age-related diseases. Frailty phenotype is an objectively measured indicator of advanced-stage aging that is characterized by organism-level dysfunction. In contrast, altered inflammation markers level signifies an earlier stage between cellular abnormalities and systems dysfunction. Results of human observational studies and randomized controlled trials indicate that these measures, albeit simple, greatly facilitate classification of older patients with cancer, chronic kidney disease, cardiovascular diseases and type 2 diabetes mellitus into groups that vary in disease incidence, prognosis and therapeutic response/toxicity. As the detailed mechanisms underlying the complex biologic process of aging are unraveled in the future, a larger array of biomarkers that correlate with biologic aging at different stages will be discovered.

    Objective To investigate the signal intensity and apparent diffusion coefficient (ADC) of bone marrow of normal adult man on diffusion weighted imaging (DWI).Methods Fifteen healthy volunteers and thirty-eight patients with benign prostatic hyperplasia or normal prostate were enrolled in this study, with age range 28-82 years old (mean 55.26 ± 18.05 years). All people were examined with large field DWI on a 3.0T magnetic resonance scanner, which ranges from the top of head to the lower limb. The signal-to-noise ratio (SNR) on the DWI and ADC of lumber vertebra at renal hilum level, left ilium and superior segment of left femur were measured. The measured SNR and ADC value of the above sites were compared by one way analysis of variance and their correlations with age were investigated by Pearson's correlation analysis. Results The SNR of lumber vertebra, left ilium and left femur showed no significant difference (F = 0.271, P = 0.763). The SNR of lumber vertebra (r = 0.309, P = 0.024) and left ilium (r = 0.359, P = 0.008) showed positive correlation with age, while the SNR of left femur showed no correlation with age (r = -0.163, P = 0.283). The ADC of lumber vertebra [(0.617 ± 0.177) ×10-3 mm2/s] was significantly higher than that of left ilium [(0.404 ± 0.112)×10-3 mm2/ P < 0.001] and left femur [(0.362 ± 0.092)×10-3mm2/s, P < 0.001], while the ADC of left ilium and left femur had no significant difference. The ADC of lumber vertebra, left ilium and left femur showed no correlation with age. Conclusion Understanding of age-related changes of normal adult bone marrow on DWI is very important to differentiate the normal bone marrow and abnormal lesions.

    Major long-range white matter pathways (cingulum, fornix, uncinate fasciculus [UF], inferior fronto-occipital fasciculus [IFOF], inferior longitudinal fasciculus [ILF], thalamocortical [TC], and corpus callosal [CC] pathways) were identified in eighty-three healthy humans ranging from newborn to adult ages. We tracked developmental changes using high-angular resolution diffusion MR tractography. Fractional anisotropy (FA), apparent diffusion coefficient, number, length, and volume were measured in pathways in each subject. Newborns had fewer, and more sparse, pathways than those of the older subjects. FA, number, length, and volume of pathways gradually increased with age and reached a plateau between 3 and 5 years of age. Data were further analyzed by normalizing with mean adult values as well as with each subject's whole brain values. Comparing subjects of 3 years old and under to those over 3 years old, the studied pathways showed differential growth patterns. The CC, bilateral cingulum, bilateral TC, and the left IFOF pathways showed significant growth both in volume and length, while the bilateral fornix, bilateral ILF and bilateral UF showed significant growth only in volume. The TC and CC took similar growth patterns with the whole brain. FA values of the cingulum and IFOF, and the length of ILF showed leftward asymmetry. The fornix, ILF and UF occupied decreased space compared to the whole brain during development with higher FA values, likely corresponding to extensive maturation of the pathways compared to the mean whole brain maturation. We believe that the outcome of this study will provide an important database for future reference. PMID:26948153

    2016-04-01

    This paper aims to propose a gradient of learnability as a criterion for setting priorities in pronunciation teaching. A total of 40 Korean subjects (mostly aged 12 year) were tested on their discrimination ability of English sounds before and after participating in a high variability phonetic training (HVPT) program for 4 weeks. This study shows highly promising results for pronunciation teaching with the HVPT method. First, lower level learners show greater improvements in phoneme discrimination ability compared to upper level learners. Second, consonants are better discriminated than vowels and greater improvements are seen with consonant contrasts than with vowels that have a lower functional load. Third, many of the sounds with high functional load have a high learnability. Fourth, greater improvements are seen with sounds that are poorly identified before the training than sounds that are well-identified. Fifth, young learners also benefit from the HVPT, much like highly motivated adult learners. A learnability gradient was established on the basis of the phoneme learnability index and the pairwise learnability index. On the basis of the constructed gradient of learnability and the concept of functional load, a set of priorities was provided for teaching English pronunciation to young Korean learners.

  5. Relationship between blood manganese and blood pressure in the Korean general population according to KNHANES 2008

    International Nuclear Information System (INIS)

    Introduction: We present data on the association of manganese (Mn) level with hypertension in a representative sample of the adult Korean population who participated in the Korean National Health and Nutrition Examination Survey (KNHANES) 2008. Methods: This study was based on the data obtained by KNHANES 2008, which was conducted for three years (2007-2009) using a rolling sampling design involving a complex, stratified, multistage, probability-cluster survey of a representative sample of the noninstitutionalized civilian population of South Korea. Results: Multiple regression analysis after controlling for covariates, including gender, age, regional area, education level, smoking, drinking status, hemoglobin, and serum creatinine, showed that the beta coefficients of log blood Mn were 3.514, 1.878, and 2.517 for diastolic blood pressure, and 3.593, 2.449, and 2.440 for systolic blood pressure in female, male, and all participants, respectively. Multiple regression analysis including three other blood metals, lead, mercury, and cadmium, revealed no significant effects of the three metals on blood pressure and showed no effect on the association between blood Mn and blood pressure. In addition, doubling the blood Mn increased the risk of hypertension 1.828, 1.573, and 1.567 fold in women, men, and all participants, respectively, after adjustment for covariates. The addition of blood lead, mercury, and cadmium as covariates did not affect the association between blood Mn and the prevalence of hypertension. Conclusion: Blood Mn level was associated with an increased risk of hypertension in a representative sample of the Korean adult population. - Highlights: → We showed the association of manganese with hypertension in Korean population. → This study was based on the data obtained by KNHANES 2008. → Blood manganese level was associated with an increased risk of hypertension.

    Full Text Available Population aging is escalating in numerous countries worldwide; among them is Taiwan, which will soon become an aged society. Thus, aging successfully is an increasing concern. One of the factors for achieving successful aging (SA is maintaining high physical function. The purpose of this study was to determine the physical fitness factors associated with SA in Taiwanese older adults (OAs, because these factors are intervenable. Community-dwelling OAs aged more than 65 years and residing in Northern Taiwan were recruited in this study. They received a comprehensive geriatric assessment, which includes sociodemographic data, health conditions and behaviors, activities of daily living (ADL and instrumental ADL (IADL function, cognitive and depressive status, and quality of life. Physical fitness tests included the grip strength (GS, 30-second sit-to-stand (30s STS, timed up-and-go (TUG, functional reach (FR, one-leg standing, chair sit-and-reach, and reaction time (drop ruler tests as well as the 6-minute walk test (6MWT. SA status was defined as follows: complete independence in performing ADL and IADL, satisfactory cognitive status (Mini-Mental State Examination ≥ 24, no depression (Geriatric Depression Scale < 5, and favorable social function (SF subscale ≥ 80 in SF-36. Adjusted multiple logistic regression analyses were performed. Among the total recruited OAs (n = 378, 100 (26.5% met the aforementioned SA criteria. After adjustment for sociodemographic characteristics and health condition and behaviors, some physical fitness tests, namely GS, 30s STS, 6MWT, TUG, and FR tests, were significantly associated with SA individually, but not in the multivariate model. Among the physical fitness variables tested, cardiopulmonary endurance, mobility, muscle strength, and balance were significantly associated with SA in Taiwanese OAs. Early detection of deterioration in the identified functions and corresponding intervention is essential to

    The purpose of this study was to better understand how older adults self-regulate driving, and to identify differences by age, sex, and health-related functioning. Michigan drivers over age 64 were surveyed by telephone (n=961, age [mu=74.2, sigma=5.8], 56% female) about their driving-related behaviors, physical functioning, and health. Respondents were presented with scenarios involving driving to an important appointment under adverse conditions (rainy stormy weather, on alternate route in heavy freeway traffic, 200-mile trip on unfamiliar roads). Generalized logit models examined outcomes for each scenario: driving as usual, driving with modifications, and not driving. Results indicate that the effect of sex on self-regulation was significant and greater than that of age and physical functioning. Women were more likely to self-regulate by not driving. Odds ratios and 95% confidence limits for each scenario for women vs. men are 6.8 (3.8-2.0), 6.5 (3.6-12.0), and 17.7 (11.0-28.6). The effect of sex on self-regulation by modifying driving was smaller and significant only in scenarios 2 and 3. Women were more likely then men to modify driving for scenario 2 (odds ratio, 3.0 (2.0-4.5)) and scenario 3 (odds ratio 4.4 (3.1-0.1)). Overall, the study finds the relative effect of sex on self-regulation greater than that of age and physical functioning for conditions examined. PMID:18606292

    When learning about a single topic in natural reading environments, readers are confronted with multiple sources varying in the type and amount of information. In this situation, readers are free to adaptively respond to the constraints of the environment (e.g., through selection of resources and time allocation for study), but there may be costs of exploring and switching between sources (e.g., disruption of attention, opportunity costs for study). From an ecological perspective, such properties of the environment are expected to influence learning strategies. In the current study, we used a novel reading paradigm to investigate age differences in the effects of information richness (i.e., sentence elaboration) and costs of switching between texts (i.e., time delay) on selection of sources and study time allocation. Consistent with the ecological view, participants progressed from less informative to more informative texts. Furthermore, increased switch cost led to a tendency to allocate more effort to easier materials and to greater persistence in reading, which in turn, led to better memory in both immediate and delayed recall. Older adults showed larger effects of switch cost, such that the age difference in delayed recall was eliminated in the high switch cost condition. Based on an ecological paradigm of reading that affords choice and self-regulation, our study provided evidence for preservation with age in the ability to adapt to changing learning environments so as to improve performance.

    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 (Pcomparison of ICG total scores between adolescents without complicated grief (1.2 ± 3.7) and adolescent with complicated grief (3.2 ± 6.6) groups was relatively high (t=5.71, P<0.001). The data acquired from the 1,138 students was acceptable for a factor analysis (Kaiser-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. PMID:26770046

    Directory of Open Access Journals (Sweden)

    Joseph S Goveas

    Full Text Available Apolipoprotein E-ε4 (APOE-ε4 accentuates memory decline, structural volume loss and cerebral amyloid deposition in cognitively healthy adults. We investigated whether APOE-ε4 carriers will show disruptions in the intrinsic cognitive networks, including the default mode (DMN, executive control (ECN and salience (SN networks, relative to noncarriers in middle-aged healthy adults; and the extent to which episodic-memory performance is related to the altered functional connectivity (Fc in these networks. Resting-state functional connectivity MRI (R-fMRI was used to measure the differences in the DMN, ECN and SN Fc between 20 APOE-ε4 carriers and 26 noncarriers. Multiple linear regression analyses were performed to determine the relationship between episodic-memory performance and Fc differences in the three resting-state networks across all subjects. There were no significant differences in the demographic and neuropsychological characteristics and the gray-matter volumes in the carriers and noncarriers. While mostly diminished DMN and ECN functional connectivities were seen, enhanced connections to the DMN structures were found in the SN in ε4 carriers. Altered DMN and ECN were associated with episodic memory performance. Significant Fc differences in the brain networks implicated in cognition were seen in middle-aged individuals with a genetic risk for AD, in the absence of cognitive decline and gray-matter atrophy. Prospective studies are essential to elucidate the potential of R-fMRI technique as a biomarker for predicting conversion from normal to early AD in healthy APOE-ε4 carriers.
