    The purpose of this study was to establish a simple and effective risk score for type 2 diabetes mellitus (T2DM) in middle-aged rural Chinese. Total of 5453 participants aged 30–59 years from the Rural Diabetes, Obesity and Lifestyle (RuralDiab) study were recruited for establishing the RuralDiab risk score by using logistic regression analysis. The RuralDiab risk score was validated in a prospective study from Henan Province of China, and compared with previous risk scores by using the receiver-operating characteristics cure. Ultimately, sex, age, family history of diabetes, physical activity, waist circumference, history of dyslipidemia, diastolic blood pressure, body mass index were included in the RuralDiab risk score (range from 0 to 36), and the optimal cutoff value was 17 with 67.9% sensitivity and 67.8% specificity. The area under the cures (AUC) of the RuralDiab risk score was 0.723(95%CI: 0.710–0.735) for T2DM in validation population, which was significant higher than the American Diabetes Association score (AUC: 0.636), the Inter99 score (AUC: 0.669), the Oman risk score (AUC: 0.675). The RuralDiab risk score was established and demonstrated an appropriate performance for predicting T2DM in middle-aged Chinese rural population. Further studies for validation should be implemented in different populations. PMID:28209984

    Interview data gathered during 2 surveys in Anhui and Shejiang Provinces in 1986 and 1987 are used to depict changes in the social status and life situation of rural women in China in 3 age groups, 18-36, 37-55, and 56 and over. For the younger women, marriage increasingly is a result of discussion with parents, not arrangement, but 3rd-party introductions are increasing. They are active in household and township enterprises and aspire to more education and economic independence. The middle-aged group experienced war and revolution and now work nonstop under the responsibility system of household production, aspiring to university education for sons and enterprise work for daughters. The older women, while supported by their sons, live a frugal existence. In general, preference for sons is still prevalent and deep-seated. At the same time, the bride price and costs of marriage are increasing and of widespread concern. Rural socioeconomic growth is required before Confucian traditions are overcome.

    The new rural cooperative medical system (NCMS) is the primary form of social insurance in rural China. This study aims to explore how the NCMS influences the health care seeking behaviors of middle-aged and older Chinese, considering the family and community contexts. A series of multi-level (three-level) models using data from the first wave of the China Health and Retirement Longitudinal Study (CHARLS) are used. We find that the presence of NCMS coverage has a statistically significant association with seeking inpatient and outpatient care but not physical checkups among middle-aged and older rural Chinese: Rural residents insured by NCMS were more likely to seek inpatient and outpatient care than people who were not insured. Other factors at the individual level (such as self-perceived health and number of doctor-diagnosed chronic diseases), the family level (such as living arrangements and household expenditures), and the community level (such as the presence of township hospitals within the community) are also significant predictors of health care seeking behaviors.

    Guided by the socio-environmental theoretical framework, this study examined factors associated with life satisfaction experienced by older Chinese adults living in rural communities. The data used in this study were extracted from the Sample Survey on Aged Population in Urban/Rural China conducted by the China Research Center on Aging in 2000. This study included 10,084 rural older adults in mainland China. In this study 60.2 % of rural older adults were satisfied with their lives. Results from a multinomial logistic regression analysis showed that life satisfaction reported by rural older Chinese adults was significantly related to education, financial resources, self-rated health, financial support from children, satisfaction with children's support, house sitting for their children, visiting neighbors, and being invited to dinner by neighbors. Research and policy implications of these findings are also discussed.

    There have been a limited number of population-based studies investigating the associations between cardiovascular disease risk factors and early age-related macular degeneration (AMD). A total of 7,557 eligible people aged 30 or older were recruited from 2006 to 2007. Cardiovascular risk factors and serum lipids including total cholesterol, total triglycerides, low density lipoprotein cholesterol, high density lipoprotein cholesterol, and fasting plasma glucose, and urines were assessed. Digital photographs of the optic disk and macula fields (Early Treatment of Diabetic Retinopathy Study) were taken and graded after the modified Wisconsin Age-related Maculopathy Grading System. Logistic regression models were constructed to assess odds ratios and 95% confidence intervals. Cases of late AMD were excluded. Of 6,577 subjects included in the analysis, there were 200 (3.04%) cases with early AMD. Multivariate analysis showed that higher age, untreated hypertension, coronary heart disease, and smoking were associated with an increased risk of early AMD. After adjusting for other variables in the final model, no variable was significantly associated with hyperpigmentation while smoking was significantly associated with an increased risk of hypopigmentation; higher age and any cardiovascular disease were associated with an increased risk of large drusen, and higher age, smoking, untreated hypertension, and coronary heart disease were associated with an increased risk of soft drusen. Our findings support the associations between smoking, coronary heart disease, and early AMD.

    China is an urban and rural social model country. In the past three decades, the developing speed of rural areas has been much slower than urban areas, which may lead to the differences in dietary patterns. This study aimed to investigate the disparities of dietary structures from urban and rural children, and to analyze the effects of different dietary patterns on their adverse outcome. Among 1590 students, aged 11 years to 17 years, from primary and middle schools, a cross-sectional study was conducted. There were three dietary patterns recognized: Westernization structure, meat diet structure, and Western and Chinese structure. Compared with rural students, more urban students were in the highest categories of the whole dietary patterns (p rural-urban disparity in dietary patterns was found in our study, and different dietary patterns were associated with the risk of some adverse outcomes. Therefore, there were different prevalences of the adverse outcomes between rural and urban students.

    Preterm birth and small for gestational age (SGA) are strong indicators of neonatal adverse outcomes. With the growing importance of preterm SGA infants, we aim to evaluate the prevalence and risk factors for preterm SGA in China. We analyzed the data of parents and infants from a population-based cohort research of the free National Pre-pregnancy Checkups Project (NPCP) in rural China. Only singleton live births that occurred between 24 weeks +0 days and 36 weeks +6 days of pregnancy were included in this study. SGA was defined as birth weight less than the 10th percentile of the reference birth-weight-for-gestational-age population. A multiple logistic regression model was built using the statistically significant variables from the 371 variables in the questionnaire. A total of 11,474 singleton, preterm, live-birth infants were included. Of the total infants, 317 (2.77%) were preterm SGA infants. A higher risk of preterm SGA infants was observed among mothers who were on oral contraceptives (OR: 8.162, 95% CI: 1.622-41.072), mothers who had syphilis (OR: 12.800, 95% CI: 1.250-131.041), and mothers with a high eosinophil percentage (OR: 13.292, 95% CI: 1.282-135.796). Maternal intake of folic acid at least 3 months before pregnancy (OR: 0.284, 95% CI:0.124-0.654) and paternal intake of egg and meat (OR: 0.097,95% CI:0.030-0.315) were protective factors. Compared with North China, the incidence of preterm SGA infants was higher in South China. Preterm SGA infants were associated with both maternal and paternal factors.

    2003-01-01

    Census data of 2000 indicated that the Chinese population aged 65 and over had accounted for 7% of the total population. In urban areas, in particular, that ratio was 6.30% and in rural areas, it was 7.35%. On average, China had entered an aging society. In recent years, old-age support in rural China has caught the attention of government officials and scholars alike. This is because rural households have undergone drastic transformation in size and structure as a result of the enforcement of the family planning policy. Coupled with the urbanization process andmassive migration of rural laborers into cities, the aging process in rural China has accelerated,challenging the traditional pattern of old-age support in rural China.

    Purpose There is a dearth of data on the association of internal migration with mental health in young rural Chinese. This study aims to explore the associations between migrant status, mental health, and suicidal behaviors in young rural Chinese. Methods We recruited 1,646 rural subjects aged 16–34 years, of whom 756 were migrant workers and 890 non-migrants, from ten representative villages in rural Sichuan Province, the southwestern part of China. To assess subject's depressive symptoms and general psychological quality of life (psycho-QOL), the study protocol included the Centre for Epidemiological Studies Depression Scale, and psycho-QOL subscale of the World Health Organization's QOL Questionnaire-Brief Version, in addition to structured questions regarding one-year suicidal thoughts and behaviors (serious ideation, plan, and attempt), socio-demographic, social support, and physical health information. Results After adjustment for confounders, migrant workers had relative to non-migrant rural residents a decreased risk for depression (OR = 0.69, P = 0.026), but comparable risk for poor psycho-QOL (OR = 0.91, P = 0.557) and one-year suicidal behaviors (OR = 0.59–1.10, P = 0.19–0.90). Migrant status only accounted for 0.5, 2.8, 4.7, 9.8, and 12.6 % of the total explainable variance for suicide attempt, poor psycho-QOL, suicide plan, depression and serious suicide ideation, respectively. Conclusion Our findings suggested that among young rural Chinese there were no significant associations involving migrant status and poor psycho-QOL or one-year suicidal behaviors, while migrant status significantly correlated with a decreased risk of depression. The unique contribution of migrant status to mental health among young rural Chinese participants in this study was very small. PMID:25403568

    China has become a country with an aging population. Compared with the aged in urban areas, the aged in rural areas have low income and are subject to social security deficiencies; the oldest among them are the most vulnerable group. If an effective mechanism for handling health risk is not available, the poor health of the rural elderly will cause an increase in their poverty level, which in turn will cause their health to become worse. Therefore, it is essential to analyze the current situation regarding rural population aging in China and to develop countermeasures. Data from 4 national health services surveys were used to analyze the differences between urban and rural populations. The results of the analysis revealed that the aged population in rural areas has poor health; economic security for the aged population is insufficient; and resources for the aged are lacking in rural areas. The Chinese government should improve medicare for the aged in rural areas, and establish a medical treatment subsidy system and a medical support system for the aged in rural areas.

    Background In exploration of the risk factors of the Chinese rural young suicide, previous researchers found low prevalence of mental problems, high degree of impulsivity, and great proportion of lethal pesticide consumption. It noticed that some of the young suicides in rural China did not intend to die from the suicidal behavior which was only instrumentally used for certain gains. Aims This study aims to look into the characteristics of those young suicides who did not really intend to die and compare them with those young suicides who had a strong intent to die. Methods Subjects were 386 suicides aged 15-34 years in the rural areas of three provinces in China. The data were obtained by psychological autopsy method. The degree of suicidal intent of the subjects was evaluated by the first 8 items of Beck’s Suicide Intent Scale (SIS). Results It was found that those suicides who had a strong intent of death were more likely to have higher age, more years of education, live alone, and suffer mental disease. On the other hand, the low intent suicides were more likely to have pesticides at home and to be impulsive. In other words, pesticides and impulsivity killed some Chinese rural young men and women who did not really want to die by suicide. Conclusion Findings of the study may be translated into practical measures in suicide prevention in China as well as elsewhere in the world. PMID:25497170

    Full Text Available Higher selenium level has been hypothesized to have the potential to reduce the risk of cardiovascular diseases including dyslipidemia. However, results from previous studies are inconsistent. This study aims to determine the association between selenium level and dyslipidemia in elderly Chinese with relatively low selenium status.A cross-sectional study of 1859 participants aged 65 or older from four rural counties in China was conducted. Serum total cholesterol (TC, triglycerides (TG, high density lipoprotein-cholesterol (HDLC and low-density lipoprotein-cholesterol (LDLC, nail selenium concentration and APOE genotype were measured in all subjects. The four types of dyslipidemia were defined as >5.17 mmol/L for High-TC, >1.69 mmol/L for High-TG, >3.36 mmol/L for High-LDLC, and <1.04 mmol/L for Low-HDLC according to Chinese Guidelines on Prevention and Treatment of Dyslipidemia in Adults. Logistic models adjusting for age, gender, APOE genotype, body mass index, alcohol consumption, smoking, physical activity, medication use for cardiovascular diseases were used to examine the relationship between selenium levels and the risk of dyslipidemia.Mean nail selenium concentration was 0.465 μg/gin this sample. Rates for High-TC, High-LDLC, High-TG, Low-HDLC were 18.13%, 13.23%, 12.21% and 32.76% respectively. Results from logistic models indicated that higher selenium levels were significantly associated with higher risk of High-TC, High-LDLC and lower risk of Low-HDLC adjusting for covariates (p < 0.0001. Compared with the lowest selenium quartile group, participants in selenium quartile groups 2, 3 and 4 had significantly higher rates of High-TC, High-LDLC, High-TG, and lower rate of Low-HDLC adjusting for covariates. No significant association was observed between selenium level and the risk of High-TG. APOEε4 carriers had higher rates of High-TC and High-LDLC. There was no interaction between selenium level and APOE with the rates of

    Full Text Available With an increase in rural-to-urban migration, a rapidly aging population, and the rising risk of developing noncommunicable diseases in China, it is important to understand the epidemiology of physical activity (PA and health in the context of disease prevention and population health. Despite its public health importance, there is a significant lack of knowledge about PA in older Chinese adults that may hamper primary prevention efforts of health promotion in an increasingly aging population. To fill this gap, this article presents a narrative review of PA in the older Chinese adult population with a special focus on residential settings (i.e., urban and rural. Using existing studies, the review examines overall PA patterns and their correlates and discusses public health implications and future research. Although there are some preliminary indications of urban and rural differences in PA in the aging population in China, continued research efforts are needed to facilitate primary prevention efforts aimed at reducing noncommunicable diseases and promoting an active lifestyle among the largest population of older people in the world.

    Xinghu Zhou

    Full Text Available BACKGROUND: It is essential to understand how we can prevent and treat the epidemic of depression. Several studies have reported the prevalence of depressive symptoms in the urban population in China, but there is a lack of information regarding the prevalence of depression in rural populations. OBJECTIVE: To understand the prevalence of depression in a rural Chinese population and to analyze the risk factors for depression. METHODS: This study used a cross-sectional approach. A total of 11,473 subjects were surveyed and completed the Patient Health Questionnaire-9 (PHQ-9 and the World Health Organization Quality of Life Brief scales. Living conditions, per capita income, marital status, and information about dietary health and chronic disease status were assessed. RESULTS: The prevalence of depressive symptoms in the population was 5.9%. The prevalence in women (8.1% was higher compared with men (3.5% and also increased with age. The per capita income level, amount of sleep obtained per day, education level, weekly consumption of meat and beans or bean products, salt intake, and chronic disease status were associated with depressive symptoms. The quality of life of individuals with a score less than 10 points on the PHQ-9 was significantly better compared with individuals with a score greater than 10. CONCLUSION: The prevalence of depressive symptoms among rural population is higher than some southern cities in China. Dietary patterns may be an important risk factor linked to this disorder in the Chinese rural population.

    Full Text Available While northern and southern Chinese are genetically correlated, there exists notable environmental differences in their living conditions. This study aimed to evaluate validity of the southern Chinese reference dataset for dental age estimation applied to northern Chinese. Dental panoramic tomographs of 437 northern Chinese aged 3 to 21 years were analysed. All the left maxillary and mandibular permanent teeth plus the 2 third molars on the right side were scored based on Demirjian’s classification of tooth development stages. Mean and standard error of dental age were obtained for each tooth development stage, followed by random effect meta-analysis for mean dental age estimation. Validity of the method was examined through measures of agreement (95% limits of agreement, standard error of measurement, and Lin’s concordance correlation coefficient and measure of reliability (Intraclass correlation coefficient. On average, the estimated dental age overestimated chronological age by only around 1 month in both females and males. The Intraclass correlation coefficient values were 0.99 for both sexes, suggesting excellent reliability of the method. Reference dataset for dental age estimation developed on the basis of southern Chinese was applicable for use among the northern Chinese.

    Hundreds of years ago, the ancient Chinese implemented several outstanding projects to cope with the changing climate and violent floods. Some of these projects are still in use today. These projects evolved from the experience and knowledge accumulated through the long coexistence of people with nature. The concepts behind these ancient stormwater management practices, such as low-impact development and sustainable drainage systems, are similar to the technology applied in modern stormwater management. This paper presents the cases of the Hani Terrace in Yunnan and the Fushou drainage system of Ganzhou in Jiangxi. The ancient Chinese knowledge behind these cases is seen in the design concepts and the features of these projects. These features help us to understand better their applications in the contemporary environment. In today's more complex environment, integrating traditional and advanced philosophy with modern technologies is extremely useful in building urban and rural stormwater management systems in China.

    Full Text Available Plasma homocysteine (Hcy is a modifiable, independent risk factor for cardiovascular disease (CVD and is affected by both environmental and genetic factors. This study aimed to describe the gender- and age-specific distribution of Hcy concentration for 1117 subjects aged 10–66 years, a subset of a community-based rural Chinese twin cohort. In addition, we examined environmental and genetic contributions to variances in Hcy concentration by gender and age groups. We found that the distribution pattern for Hcy varied by both age and gender. Males had higher Hcy than females across all ages. Elevated Hcy was found in 43% of male adults and 13% of female adults. Moreover, nearly one fifth of children had elevated Hcy. Genetic factors could explain 52%, 36% and 69% of the variation in Hcy concentration among children, male adults and female adults, respectively. The MTHFR C677T variant was significantly associated with Hcy concentrations. Smokers with the TT genotype had the highest Hcy levels. Overall, our results indicate that elevated Hcy is prevalent in the children and adults in this rural Chinese population. The early identification of elevated Hcy will offer a window of opportunity for the primary prevention of CVD and metabolic syndrome.

    2014-09-01

    Full Text Available This paper uses qualitative methodology to explore the experience of growing old in rural Appalachia. Given the growing population of older adults seeking and utilizing services, it is important to understand the challenges and specific needs related to aging. Within the context of rural Appalachia, these challenges and needs may be different than those in urban areas or areas outside of the region itself. From interviews with 14 geriatric service providers in rural southeast Ohio, the authors were able to identity three prevalent themes associated with aging in rural North Central Appalachia: scarcity of resources, valuing neighbors and family, and the prevalence of drug use. These findings suggest that preparation and ongoing training of rural geriatric social workers should include attention to topics such as substance abuse and strengthening social support networks that often exist in these regions.

    2015-11-01

    Full Text Available Background: The Chinese government has been introducing reform policies to improve the existing social security system, including the old age insurance schemes for rural-urban migrants. However, there are still challenges in the current system that hinder migrants who move frequently from participating in old age insurance schemes. Objective: The objectives of this paper are to describe the current coverage of old age insurance amongst migrant workers and examine the associated individual, household, and geographical factors, and to predict the probability of old age insurance participation among rural-urban migrants by province and relevant migrant characteristics. Methods: Data for the analysis are drawn from the 2011 Migrant Dynamics Monitoring Survey in China. The sample consists of 110,005 migrant workers with rural household registration. The analysis considers multinomial logistic regression with type of old age insurance as the outcome variable. Results: Of all rural-urban migrant workers nationwide, 16.4Š have participated in the Basic Pension Insurance for urban employees, 9.8Š in the New Old Age Pension scheme for rural residents, 3.3Š are covered by both schemes, and 70.5Š have no coverage with any old age pension scheme. Migrants moving within provinces or from relatively wealthy households are more likely to participate in an old age insurance scheme than those moving across provinces or from relatively poor households. Migrants' occupational status also influences their participation in old age pension schemes. The predicted probability of participation varies across China by province.

    2014-11-01

    Quantitative measurement of the prevalence of cigarette sharing and gifting in a town in rural China and evaluation of the impact of these practices on individual smoking habits and family expenditures. An interview-based cross-sectional study of 105 households in rural Hunan, China tabulated household cigarette gifting and expenditures. Individual smoking and cigarette sharing activities were also recorded among 198 household members aged >15 years who were resident for at least 6 months. With regard to sharing cigarettes, 92% of men and 19% of women reported being offered a cigarette within the past week. Among previous and current smokers who had attempted to quit smoking, 90% reported that their friends had tried to dissuade them from quitting by tempting them with cigarettes. Concerning gifting cigarettes, 74% of households reported sending packaged cigarettes as gifts during the Chinese New Year Festival at an average expense of 2.8% of household annual income. Although households received an average of 12.4% of their annual cigarette consumption in the form of gifts during the Chinese New Year Festival, no association was found between the amount of cigarettes received by a household and the annual cigarette consumption for that household. Both gifting and sharing cigarettes are common in rural China. Gifting of cigarettes during the New Year Festival is a significant expenditure affecting both smoking and non-smoking households and may be an opportunity for additional mass media marketing. Among current and former smokers, sharing cigarettes in China is a major impediment to smoking cessation. Published by the BMJ Publishing Group Limited.

    Junling Gao

    Full Text Available The present study sought to investigate the associations between workplace social capital and hazardous drinking (HD among Chinese rural-urban migrant workers (RUMW.A cross sectional study with a multi-stage stratified sampling procedure was conducted in Shanghai during July 2012 to January 2013. In total, 5,318 RUMWs from 77 workplaces were involved. Work-place social capital was assessed using a validated and psychometrically tested eight-item measure. The Chinese version of Alcohol Use Disorders Identification Test (AUDIT was used to assess hazardous drinking. Control variables included gender, age, marital status, education level, salary, and current smoking. Multilevel logistic regression analysis was conducted to test whether individual- and workplace-level social capital was associated with hazardous drinking.Overall, the prevalence of HD was 10.6%. After controlling for individual-level socio-demographic and lifestyle variables, compared to workers in the highest quartile of individual-level social capital, the odds of HD for workers in the three bottom quartiles were 1.13(95%CI: 1.04-1.23, 1.17(95%CI: 1.05-1.56 and 1.26(95%CI: 1.13-1.72, respectively. However, contrary to hypothesis, there was no relationship between workplace-level social capital and hazardous drinking.Higher individual-level social capital may protect against HD among Chinese RUMWs. Interventions to build individual social capital among RUMWs in China may help reduce HD among this population.

    The aim of this study was to determine how malnutrition rates change in young Chinese children when 2006 World Health Organization (WHO) growth standards are used instead of 1978 WHO/National Center for Health Statistics reference. Cross-sectional survey data were used from rural western China and the Tibet region. The heights and weights of children of Tibet). The prevalence of underweight was lower in rural western China (7.7% vs. 11.7%) than rural Tibet (13.1% vs. 15.3%). For all ages, the prevalence of stunting increased and the greatest relative increase appeared in the first six months (102.9% in rural western China vs. 134.9% in rural Tibet). With respect to underweight, the relative increase occurred only during the first six months (314.3% in rural western China vs. 48.1% in rural Tibet); however, the reduction was observed in other age groups. For young Chinese Han and Tibetan children, the difference in estimation of malnutrition between two references differed in magnitude. The scale of change in the prevalence rates of stunting and underweight is much greater when 2006 reference was introduced.

    Full Text Available Purpose: This study aimed to describe the system of continuing medical education (CME in the Guangxi Zhuang Autonomous Region and to ascertain the perceived needs related to that system, in order to improve the performance of health professionals in Chinese township health centers (THCs. Methods: In-depth key informant interviews were conducted to gain insights into the current CME system. A cross-sectional survey using a self-administered structured questionnaire was also carried out from March to August 2014 in order to identify perceived needs among THC personnel in the Guangxi Zhuang Autonomous Region. Logistic regression was used to identify factors related to respondents’ interest in pursuing different levels of degree study. Results: The areas of need perceived by the respondents included general clinical competence and emergency or first aid knowledge. Most respondents wanted to study at medical colleges in order to obtain a higher degree. Respondents aged below 45 years with neutral or positive attitudes about the benefit of degree study for the licensure examination were more likely to attend a bachelor-level CME program than their older peers and respondents with negative attitudes towards degree study. Female respondents and respondents aged below 45 years were more likely to attend a junior college CME program than males and older respondents, respectively. Conclusion: It is necessary to develop degree-linked CME programs to meet the need for young health professionals in Chinese THCs; therefore, this programs can improve the expertise of poorly educated young health workers, who overwhelm rural Chinese heath systems.

  11. Population Ageing in Rural Settlements in the Republic of Croatia

    2016-08-01

    Full Text Available One of the basic demographic characteristics of Croatia is the inherited dispersed population density with a large number of small settlements and the undeveloped system of regional and micro-regional centres. Such settlement structure was entirely inappropriate in the conditions of accelerated and urban-based industrialization after the Second World War. This period was characterised by a mass transition of agricultural population into non-agricultural activities, along with the abandonment of rural settlements. In addition to the strong emigration from rural areas in which younger age groups participated for the most part, there was a continuous reduction in fertility, too. All this has led to the narrowing of young age groups and consequently to the increase in the proportion of the elderly. An important factor of demographic ageing is the reduction in mortality of persons over 30 years of age and longer life respectively. Life expectancy of the Croatian population was 64.8 years in 1960 and 77.2 years in 1972. The average age constantly increased: it was 32.5 years in 1961, 35.4 in 1981 and it reached the high 41.7 years in 2011. The aggression and war against Croatia happened in the 1990s. Dramatic events affected the general social conditions and processes, strongly accelerating negative demographic trends. All this had further affected the socio-demographically eroded rural areas. There was a particularly difficult situation in the regions directly affected by the war; part of these areas had had the features of extreme demographic regression before the war sufferings and the war only further strengthened it. The overall population of Croatia is characterised by decreasing fertility, natural depopulation (negative natural change, total depopulation (since 1990 and intense population ageing. The duration and intensity of these processes clearly testifies to the demographic development of Croatia being very unfavourable. All this also

    2008-04-01

    The rural economic situation in China-with a living standard mostly at subsistence level-lags far behind the prosperous development in the cities and coastal areas. To balance this disequilibrium, comprehensive concepts and endeavors are necessary keeping in view all-not just economic-interests and needs that contribute to lively rural identities. In this context the role of agriculture, where still 50% of the Chinese population are working, will be newly defined, and sustainability concepts can help to find a readjusted position within the Chinese economy focusing on environmental health and food safety as main targets of political and other supporting measures. Within the SUCCESS project, a Concept of Sustainable Agriculture was developed and it drafts one conceivable relation between the exposure to natural resources and economy and tries to find new answers to the broad range of rural challenges in China. It is a qualitative model and, therefore, not always fully applicable, but in the concrete situation of villages, it shows possible directions of sustainability-oriented development by considering the typical local potentials. In the Chinese context that means identifying the different functions of agriculture-the well-known and the hidden-to make them explicit for the Chinese public and therewith to give them new significance. The article is based on a 3-years study within the EU-China Project SUCCESS with field research in four Chinese rural communities. It analyzes the agricultural sustainability potential of these selected villages against the background of massive structural changes within the next 20 years in rural China. Starting from the current agricultural reality, based on a qualitative analysis of the actual situation, local potentials and needs towards sustainable production and marketing are identified, and possible functions of the Chinese agriculture are formulated for the future.

    Full Text Available Global literature has suggested a negative impact of acculturative stress on both physical and mental health among international migrants. In China, approximately 20 percent of its population is rural-to-urban migrant workers and there are significant cultural differences between rural and urban societies, but no data are available regarding the acculturative stress of Chinese migrant workers. This study aimed to explore the forms and contexts of acculturative stress among Chinese migrant workers.Qualitative data were collected from four focus group discussions with 17 Chinese rural-to-urban migrant workers and three individual interviews with three medical professionals who provided mental health services for factory-workers in Shenzhen, China.The data in the current study showed that rural-to-urban migrant workers in China had experienced various forms of acculturative stress including difficulties in adapting to the environment, work-related stress, family-related stress, financial hardship, and lack of sense of belonging to cities.Rural-to-urban migration in China is a challenging transition with significant acculturative stress and demands for major adjustments among migrant workers. The assessment and management of acculturative stress is a necessary first step in providing mental health services to migrant workers.

    2006-01-01

    During the course of urbanization and industrialization, a growing number of farmers have become landless as local governments have bought out their land for non-agricultural uses.Even in the localities where the industrialization process absorbs a vast majority of rural labor, the questions of how to compensate for the economic shock on the rural landless and how to alleviate and eliminate mental suffering as a result of losing land have always been a challenge to government capacity in social stabilization and ayardstick to measure social justice in local communities. In the administration areas of Suzhou City in Jiangsu Province,governments at all levels have successfully coped with this challenge. By means of "swapping land for old-age support" and income redistribution, Suzhou municipality has not only met the demand on land for urbanization and industrialization while maintaining social stability,but also laid a foundation for establishing an integrated pension system for both urban and rural residents. Such a system has changed the tradition of farmers ' households relying on land to deal with economic risk and of the aged depending on their sons for livelihood support in rural society.

    To analyze the status of vitamin A deficiency among children under 5 years old in poor rural areas of 6 Western Chinese provinces in 2009. The study subjects involved 2091 children from a program - 'Appropriate measurements in improving children under-nutrition in poor rural areas'. In 2009, prevalence of vitamin A deficiency among children under 5 years old from the poor rural areas of 6 western Chinese provinces was 20.2%, with boys as 20.6% and girls as 19.7%. Prevalence rates of vitamin A deficiency among children under 5 years old in the highest and lowest areas were seen in Gansu (25.5%) and Guangxi (12.2%) provinces, respectively. The peak of vitamin A deficiency prevalence fell in the 6 - 11 months age group. The prevalence of vitamin A deficiency declined along with the increase of age. from this study demonstrated that vitamin A deficiency among children under 5 years old appeared to be a serious public health problem in the poor rural areas of 6 Western Chinese provinces. Education on reasonable ways of feeding and provision of complementary nutrients to children with vitamin A deficiency, should be the key points in the prevention and control programs on this problem.

    Researchers have been examining the relationship between obesity and hypertension. However, whether overall or abdominal obesity better explains senior adults' hypertension has not been studied. The purpose of the study was to examine whether body mass index or waist circumference better predicts hypertension in Chinese senior adults and how the magnitude of the relationship is attenuated as they continue to age. The study was based on the 2010 National Physique Monitoring data. There were 7,542 senior adults aged 60-69 years living in urban, suburban, and rural areas of Shanghai City. The participants were categorized into five age groups: 60-61, 62-63, 64-65, 66-67, and 68-69 years. The percentage of participants who had hypertension increased as people aged, which was mainly caused by the increase of systolic blood pressure. Logistic regression analysis showed that when body mass index or waist circumference was entered into the model, both were significant predictors for hypertension (p adults have hypertension as they age. Body mass index, and not waist circumference, better predicts Chinese senior adults' hypertension. However, age attenuates the effects of obesity on hypertension as the senior adults continue to age.

    Previous studies have examined the prevalence of psychological strains among various suicide populations. However, it is still unexamined whether psychological strains can predict suicide intent directly. We planned to explore the prevalence of psychological strains and analyze the relationship between psychological strains and suicide intent among Chinese rural young suicides. Psychological autopsy method was used to investigate the environmental and other factors of rural young suicides. Psychological strains were identified from in-depth interviews by the proxy informants of each suicide. The first 8 items of Beck's Suicidal Intention Scale (SIS) were used to estimate the suicide intent. Results showed that 96.6% of the suicides had at least one type of strain, and those suicides who had more strains tended to score higher on the suicide intent scale. The study further supports that suicide intent can be predicted by psychological strains in Chinese rural young suicides. The scanning of psychological strains can be used for suicide prevention in Chinese rural young suicides. © The Author(s) 2015.

    The Chinese kang is an ancient integrated home system for cooking, sleeping, domestic heating and ventilation. It is still widely used today in nearly 85% of rural homes in northern China. In 2004, there were 67 million kangs used by 175 million people. Existing kang designs are mostly based on the intuition and accumulation of craftsman experience. There is a trend that Chinese kang is gradually replaced by bed and coal-burning radiators, domestic heating stoves, etc. using commercial energy. As rural building heating constitutes 25% of total building energy consumption in China, we consider that the transition and new technologies for rural home heating in northern China is crucial for managing future building energy consumption in China. This paper reviews the basic heat transfer and airflow principles of Chinese kang, as well as describing the traditional grounded kang and the relatively new elevated kang. The thermal performance of the kang is shown by data from literature and field surveys. The future of Chinese kang and research needs is also briefly discussed. There is also a need for scientific study in addition to experience accumulation, to form basis for engineering design. (author)

    To assess the trend of sex disparity in hemoglobin concentration and prevalence of anemia among Chinese school-aged children from 1995 to 2010. Data were collected from 360 866 children aged 7, 9, 12, 14, and 17 years during 4 cross-sectional surveys (1995, 2000, 2005, and 2010) of the Chinese National Surveys on Students Constitution and Health. Shifts in hemoglobin concentration distributions were compared by sex. Average shifts and sex differences were calculated with quantile regression models. Logistic regression was used to estimate the prevalence odds ratio of sex for prevalence of anemia in different surveys. The mean hemoglobin concentration increased among Chinese children between 1995 and 2010, from 132.7 to 138.3 g/L in boys, and from 127.7 to 132.3 g/L in girls. The prevalence of anemia decreased from 18.8% in 1995 to 9.9% in 2010. It was higher in rural than urban children among all age groups. The prevalence odds ratios of girls versus boys for anemia increased in both urban and rural areas over time. Hemoglobin concentration and prevalence of anemia improved among Chinese school-aged children over time. Hemoglobin concentration improved faster in boys than girls and as a result the relative prevalence of anemia in girls compared with boys increased. Sex-specific preventive guidelines and public health policies for childhood anemia are needed in China. Copyright © 2017 Elsevier Inc. All rights reserved.

    Poverty is widespread among rural African elderly and associated with poor health and unsatisfactory access to health care. The purpose of this study was to determine community perception of the poorest in a community in rural Kenya, more specifically to identify factors considered by community members as associated with poverty in their midst. There is need to protect the aged members of the society from payment for health care and to include them in decision-making process. This study was undertaken in seven sites in Kisumu and Homa Bay districts in western Kenya where the Bamako Initiative was first launched, in 1987, calling on UNICEF and WHO to help accelerate the implementation of primary health care at district level, giving priority to women and children. Two household interview baseline surveys comprising 210 and 87 households, respectively, corroborated by the more qualitative approaches of participatory rural appraisal (PRA) and focus group discussions were conducted. This article analyses the importance of ageing as perceived by the communities as a factor associated with poverty.

    This paper examines the effect of age at menarche on children ever born (CEB). We use data from the 1997 Sample Survey of Population and Reproductive Health conducted by the China Population Information and Research Center and the State Family Planning Commission. Poisson regression models are estimated for 10,919 ever married Chinese Han women. The influence of a woman's age at menarche on her CEB is examined while controlling for the social effects of rural/urban residency, education, her number of fecund years, whether her first birth occurred before or after the initiation of China's one child policy, and her age at first marriage. The results support our hypothesized positive association between age at menarche and CEB. That is, the later a woman's age at menarche, the greater her number of children ever born. Holding the other five independent variables constant, we show that for every additional month in age at menarche, a Chinese Han woman's mean number of children ever born increases by 0.5 percent. Some of the implications of these results are explored.

    Full Text Available The primary objective of this study was to investigate the prevalence and risk factors of restless legs syndrome (RLS in an adult Chinese population living in a rural community. We also aimed to determine the predictive diagnostic value of the 4-item screening questionnaire for RLS in this population.This study was designed as a 2-phase survey. In phase 1 we performed a face-to-face interview of eligible individuals living in a rural community in Shanghai using a 4-item screening questionnaire. In phase 2, sleep specialists performed a phone interview of the individuals who screened positive to diagnosis RLS.Forty-one RLS cases were confirmed among 2941 eligible individuals 18 years of age or older in the study community. The prevalence of RLS was 1.4% (95% confidence interval (CI = 1.0-1.9%, with a significantly higher rate observed in females (1.9% [95%CI =1.3-2.7%] than that in males (0.9% [95%CI = 0.5-1.5%], p = 0.019. The prevalence rate increased significantly with age, from 0.2% (95% CI = 0.08-0.6% in those 18-39 years old to 4.1% (95% CI = 2.1-7.9% in those ≥ 70 years old (p < 0.001. The multivariate logistic regression analysis indicated that gastritis, anemia and hypertension were risk factors for RLS. The sensitivity and specificity of the 4-item screening questionnaire used in this study were 63.4% and 97.5%, respectively.RLS prevalence is relatively low among Chinese adults living in rural Shanghai. Furthermore, population-based studies with a larger sample size and a longitudinal follow-up may help to determine the risk factors of RLS and potential interventions for RLS.

    Full Text Available Background: Women are traditionally over represented among the poor and therefore in the long run, have less access to remuneration and health resources, including health insurance and social security services. Women are disadvantaged on some fundamental economic indicators such as unemployment and access to economic resources. In 2007 in Jamaica, for instance among the 124 500 unemployed persons in the labour force, 65.4% were women (Planning Institute of Jamaica, 2008. Thus, women's health and the control that they can exercise over resources are key factors in achieving effectiveness, efficiency, and sustainability in health interventions. Aims and Objectives: This study examined the good health status of rural women in the reproductive ages of 15 to 49 years. Having extensively reviewed the literature, this paper is the first study of its kind in Jamaica and will provide pertinent information on this cohort for the purpose of public health planning. Method/Study Design: The current research extracted a sample of 3450 respondents who indicated that they were rural women ages 15 to 49 years. This sample was taken from a national cross-sectional survey from the 14 parishes in Jamaica. The survey used a stratified random probability sampling technique to draw the original 25 018 respondents. The non-response rate for the survey was 29.7%. Descriptive statistics were used to provide background information on the sample and logistic regression was used to establish a good health model. Results/Findings: Using logistic regression analyses, 6 variables emerged as statistically significant predictors of current good health status of rural women (i.e. ages 15 to 49 years in Jamaica. These are social standing (two wealthiest quintile – OR=0.524, 95%CI: 0.350,0.785; marital status (separated, divorced or widowed – OR=0.382, 95%CI: 0.147, 0.991; health insurance (OR=0.041, 95%CI: 0.024, 0.069; negative affective psychological conditions (OR=0.951, 95

    Background Pterygium is a common ophthalmic disease and an important public health problem. It may be affected by many factors such as age, gender, ultraviolet radiation exposure, and time spent outdoors. This study aimed to investigate the prevalence of pterygium and evaluate the risk factors for the development of pterygium in the aged rural population of Beijing.Methods The investigation is a population-based cross-sectional study. Participants from 198 villages of 13 suburban districts, aged 55-85 years old, were invited to complete a medical record, and 37 067 individuals were taken external ocular and fundus photos at Beijing ocular disease survey in 2008-2009. The information was uploaded by Internet and diagnosed with stages and grades by ophthalmological specialists. The prevalence, stages and grades of pterygia were observed.Results Of the 37 067 individuals, 1395 (3.76%) had pterygium. There was a significantly higher prevalence in male (5.13%) than in female (3.17%, P=0.000). The prevelence rate increased obviously with ages (x2=7.939, P=0.019) in rural Beijing. The average prevalence of 5.91% in Daxing and Fangshan districts with low latitude and low precipitation was significantly higher than that in Miyun and Huairou districts with high latitude and deep precipitation (3.17%, P=0.000). The majority of the pterygia (43.5%) were in active stage and 46.5% pterygia involved pupil area corneas. Conclusions There is a statistically significant association between latitude and precipitation of habitation region and pterygium formation. Solar radiation, especially ultraviolet exposure represents a significant environment hazard to pterygium development.

    Full Text Available Substantial evidence indicates that where readers fixate within a word affects the efficiency with which that word is recognized. Indeed, words in alphabetic languages (e.g., English, French are recognized most efficiently when fixated at their optimal viewing position (OVP, which is near the word center. However, little is known about the effects of fixation location on word recognition in non-alphabetic languages, such as Chinese. Moreover, studies to date have not investigated if effects of fixation location vary across adult age-groups, although it is well-established that older readers experience greater difficulty recognizing words due to visual and cognitive declines. Accordingly, the present research examined OVP effects by young and older adult readers when recognizing Chinese words presented in isolation. Most words in Chinese are formed from two or more logograms called characters and so the present experiment investigated the influence of fixation location on the recognition of 2-, 3-, and 4-character words (and nonwords. The older adults experienced generally greater word recognition difficulty. But whereas the young adults recognized words most efficiently when initially fixating the first character of 2-character words and second character of 3- and 4-character words, the older adults recognized words most efficiently when initially fixating the first character for words of each length. The findings therefore reveal subtle but potentially important adult age differences in the effects of fixation location on Chinese word recognition. Moreover, the similarity in effects for words and nonwords implies a more general age-related change in oculomotor strategy when processing Chinese character-strings.

    Mandarin Chinese speech sounds (vowels × tones) were presented to younger and older Chinese-native speakers with normal hearing. For the identification of vowel-plus-tone, vowel-only, and tone-only, younger listeners significantly outperformed older listeners. The tone 3 identification scores correlated significantly with the age of older listeners. Moreover, for older listeners, the identification rate of vowel-plus-tone was significantly lower than that of vowel-only and tone-only, whereas for younger listeners, there was no difference among the three identification scores. Therefore, aging negatively affected Mandarin vowel and tone perception, especially when listeners needed to process both phonemic and tonal information.

    Full Text Available OBJECTIVE: To identify the immediate economic impact of maternal death on rural Chinese households. METHODS: Results are reported from a study that matched 195 households who had suffered a maternal death to 384 households that experienced a childbirth without maternal death in rural areas of three provinces in China, using quantitative questionnaire to compare differences of direct and indirect costs between two groups. FINDINGS: The direct costs of a maternal death were significantly higher than the costs of a childbirth without a maternal death (US$4,119 vs. $370, p<0.001. More than 40% of the direct costs were attributed to funeral expenses. Hospitalization and emergency care expenses were the largest proportion of non-funeral direct costs and were higher in households with maternal death than the comparison group (US$2,248 vs. $305, p<0.001. To cover most of the high direct costs, 44.1% of affected households utilized compensation from hospitals, and the rest affected households (55.9% utilized borrowing money or taking loans as major source of money to offset direct costs. The median economic burden of the direct (and non-reimbursed costs of a maternal death was quite high--37.0% of the household's annual income, which was approximately 4 times as high as the threshold for an expense being considered catastrophic. CONCLUSION: The immediate direct costs of maternal deaths are extremely catastrophic for the rural Chinese households in three provinces studied.

    To explore mental health status and related characteristics in a sample of Chinese male rural-urban migrants. Subjects were 1,595 male rural-urban migrant workers selected though a multi-stage sample survey conducted in two cities (Hangzhou and Guangzhou). Data were collected by means of a self-administered questionnaire. Both life and work stressors were examined. Stress and mental health status were measured by the Chinese Perceived Stress Scale (CPSS) and the Chinese Health Questionnaire (CHQ), respectively. Unconditional logistic regression analysis was performed to identify factors associated with probable mental disorders. There are approximately 120 million rural-urban migrants in China. The prevalence of probable mental disorders in the sample population was 24.4% (95% CI: 23.3-25.5%), which was higher than among urban residents (20.2%, 95% CI: 18.8-21.7%). Logistic regression analysis revealed that five characteristics were positively associated with risk for probable mental disorders: originating in the South (OR = 2.00; 95% CI = 1.02, 4.00), higher life stress (OR = 7.63; 95% CI = 5.88, 10.00), staying in the city for 5-9 months each year (OR = 2.56; 95% CI = 1.67, 3.85), higher work stress (OR = 2.56; 95% CI = 1.96, 3.33), and separation from wife (OR = 2.43; 95% CI = 1.61, 3.57). Employment in machinery and transportation (OR = 0.54; 95% CI = 0.36, 0.81) and higher self-worth (OR = 0.42; 95% CI = 0.28, 0.62) were negatively associated. Findings support an urgent need to develop specific policies and programs to address mental health problems among Chinese rural-urban migrants.

  3. China's Urban and Rural Old Age Security System: Challenges and Options

    This paper reviews the development of the urban and rural old age security system in China,and discusses the challenges in the process of constructing a sustained old age security system. Although funding gaps and empty individual accounts have imposed a heavy burden on the sustainability of China's urban pension system, there is a relatively high coverage rate of 35.3 percent for urban workers. However, China's pension system provides low coverage rate for rural farmers. The more rapidly aging population and lower incomes in rural areas pose challenges to the vulnerable rural household support system. The separation of the old age security system between rural and urban areas also puts great pressure as a result of urbanization on farmers who lose their farmland. Therefore, it is urgent for China to speed up the reform of its old age security system to provide an institutional support for its economic and social transition.

    China has experienced a rapid increase in hypertension over the past decade, especially in rural. Therefore, the aim of this research is to examine the dynamic trends in urban-rural disparities in hypertension prevalence, detection, and medication use among Chinese adults from 1993 to 2011. Data were extracted from the seven latest waves of the China Health and Nutrition Survey (CHNS). We used the hukou system to distinguish between urban and rural residents. Chi-square tests were performed to examine urban-rural gaps in hypertension prevalence, detection and medication use. Multiple logistic regressions were used to confirm these disparities and to explore whether the urban-rural gaps have narrowed or widened from 1993 to 2011, after controlling for health-related behaviors, BMI, demographic variables and socioeconomic characteristics. Blinder-Oaxaca decomposition technique was also used to calculate the extent to which urban-rural disparities reflect an endowments effect or a coefficients effect. Hypertension prevalence, detection, and medication use among rural adults were significantly lower than urban adults, with the significant level at p urban-rural gaps in hypertension prevalence and medication use gradually narrowed during the period 1993-2011, whereas the gaps in hypertension detection grew wider. After controlling for confounding variables, urban adults were about 24.5, 49.4, and 89.5% more likely to be hypertensive, detected, and medicated than their rural counterparts (p urban-rural gap in hypertension detection and medication use could be attributed to coefficient difference, respectively. Although hypertension prevalence among rural adults was comparable to that of urban adults, hypertension detection and medication use of rural adults were still suboptimal. Unusually large urban-rural gaps and an expanding trend in hypertension detection deserve the attention of health policymakers and researchers.

    To provide prevalence and trends of underweight, overweight, and obesity among reproductive-age women and adolescent girls in rural China. We measured weight and height in 16 742 344 women aged 20 to 49 years and 178 556 girls aged 15 to 19 years from the National Free Preconception Health Examination Project between 2010 and 2014. Among women, the prevalence of underweight was 7.8% (95% confidence interval [CI] = 7.7%, 7.9%), and overweight or obesity was 16.5% (95% CI = 16.4%, 16.6%; World Health Organization criteria). Among adolescents, prevalence of underweight was 6.0% (95% CI = 5.7%, 6.2%; Centers for Disease Control and Prevention criteria) and overweight or obesity was 8.3% (95% CI = 7.9% to 8.8%; International Obesity Task Force criteria). According to Chinese criteria, overweight and obesity prevalence was 24.8% (95% CI = 24.7%, 24.9%) for women and 17.2% (95% CI = 16.6%, 17.8%) for adolescents, and underweight prevalence was 2.9% (95% CI = 2.8%, 3.1%) for adolescents. Considerable disparities existed in prevalence and trends within subpopulations (age groups, parity, region, education levels, and socioeconomic status). Our results reveal coexisting underweight and overweight or obesity among rural women and adolescents of reproductive age, which requires public health attention.

    Full Text Available The purpose of this study is to explore the relationships between sleep behaviors and injury occurrence among Chinese school-aged children. Data were collected with self-administered questionnaires of a cross-sectional survey which covered the school-aged children from southeastern Chinese urban and rural areas in April 2010. Information was collected on unintentional injury in the past year, sleep duration, napping and daytime fatigue, sleeping pill use, and social-demographic variables. Multivariable logistic regression analyses, controlling for confounding factors, were conducted to assess sleep-related variables that were associated with injuries. Students who slept for less than 8 h had a 30% increased risk of injury (OR: 1.30; 95%CI: 1.01–1.69 compared with those who slept for 8–9 h. Lack of napping, snoring and use of sleeping pills were significantly associated with injury. Among different genders, the slight difference in sleep behaviors predicted the occurrence of injury. Rural children displayed more sleep behaviors associated with injury than urban children. The sleep behaviors of primary school students were more negatively correlated with injury occurrence than junior/senior high school children. Consideration should be given to the prevention of problematic sleep behaviors as a potential risk factor in order to decrease injury rates and promote the health of school-aged children.

    Based on the data from the Second National Agriculture Census in 2006, this paper analyzed the absolute quantity and age structure of China rural surplus labor force by the classical approach. It showed that the migration of rural labor force was still far away from "Lewis turning point", and "mingong huang" (shortage of peasant workforce) appearing in coastal areas could be explained with the location separation between the labor-intensive industries and rural labor force. It was a feasible and an effective way to push forward the transfer of labor-intensive industries from the east coast to central and Western China to absorb the abundant supply of rural labor force.

    2010-03-01

    Older Australians living in rural areas have long faced significant challenges in maintaining health. Their circumstances are shaped by the occupations, lifestyles, environments and remoteness which characterise the diversity of rural communities. Many rural regions face threats to future sustainability and greater proportions of the aged reside in these areas. The emerging changes in Australia's climate over the past decade may be considered indicative of future trends, and herald amplification of these familiar challenges for rural communities. Such climate changes are likely to exacerbate existing health risks and compromise community infrastructure in some instances. This paper discusses climate change-related health risks facing older people in rural areas, with an emphasis on the impact of heat, drought and drying on rural and remote regions. Adaptive health sector responses are identified to promote mitigation of this substantial emerging need as individuals and their communities experience the projected impact of climate change.

There are many problems contributing to the poor effect of rural English teaching,such as outdated teaching equipment,unreasonable curriculum design,insufficient teaching staff,asymmetrical teaching content,family education and students’ personal problems. Based on the Chinese General Social Survey data,it is found that in terms of English reading,English speaking or English writing,the current English level of China’s rural residents is lagging behind. From the average,the reading level of rural residents is better than the speaking and writing level,but the paired T-test results show that there are no significant differences between them,suggesting that under the current system of rural English teaching,the English level of rural residents is constrained to a low level. To improve the rural English teaching in the future,it is necessary to pay close attention to the following aspects: stabilizing the investment in rural education; optimizing the English teaching content; converting the philosophy of education; increasing teacher training; establishing the new linkage system.

    The objectives of this study were: to compare the prevalence of hypertension, overweight and obesity in rural (Ferlo) and urban (Dakar) Senegalese populations aged 50 and over. The survey was conducted on individuals aged 50 and older living in the rural area (N=478) and in the urban area (N=220). We have collected data about age, gender, marital status, education level, and knowledge, treatment of hypertension, height, weight and blood pressure. We have observed that overweight and obesity were more prevalent in the urban area (Dakar) than in the rural one (Ferlo). The risk of overweight or obesity decreased when age increased, and women had weight problems more often than men. The prevalence of arterial hypertension was lower in rural area (55.86%) than in Dakar (66.36%), but increased at an older age. However, the logistic regression showed that these increased proportion of hypertension in Dakar is linked to the more important proportion of overweight and obese people in this area. Moreover, rates of knowledge, treatment and control of hypertension are particularly low in the rural area of Senegal. In conclusion, age-associated diseases should be better managed in Senegal, particularly in rural areas.

    Objective To assess the side effects and the continuation rate of combined oral contraceptive (COC) containing desogestrel (Marvelon ) during 12 months. Methods This was a post-marketing surveillance study on Marvelon COC among 870 healthy rural women in 5 different counties of Jiangsu Province during 12 months. Results About 24.02% of the women who used Marvelon COC experienced side effects during 12 months. Gastrointestinal disorder, bleeding/spotting and chloasma were ranked the first three in the side effects. The rate of side effects of Marvelon COC users during the first 3 months in southern area of Jiangsu was significantly higher than that of users in northern area of Jiangsu. Most of the users did not experience obvious weight changes i.e., loss or increase in weight of more than 5 kg during 12 months. Blood pressure and biochemical indicators of almost 99% among users were within the normal range. The gross cumulative continuation rate for 12 months was 83.14%; the most common medical reason for discontinuation was gastrointestinal disorder. There was an increased risk of discontinuation use among women with lower educational level.Conclusion Marvelon COC brought fewer side effects and was well accepted when applied in Chinese rural women.

    Chinese liquor aroma components were characterized during the aging process using gas chromatography (GC). Principal component and cluster analysis (PCA, CA) were used to discriminate the Chinese liquor age which has a great economic value. Of a total of 21 major aroma components identified and quantified, 13 components which included several acids, alcohols, esters, aldehydes and furans decreased significantly in the first year of aging, maintained the same levels (p > 0.05) for next three years and decreased again (p aroma component during aging process. Results of PCA and CA demonstrated that young liquor (fresh) and aged liquors were well separated from each other, which is in consistent with the evolution of aroma components along with the aging process. These findings provide a quantitative basis for discriminating the Chinese liquor age and a scientific basis for further research on elucidating the liquor aging process, and a possible tool to guard against counterfeit and defective products.

    1999-04-01

    There is increasing evidence that age at menarche has decreased in Europe and the United States during the last century and in Japan over the last several decades. Data from a community-based survey conducted in two rural counties of Anhui Province in China indicate a similar, downward secular trend in age at menarche for Chinese women. The present study shows the mean age at menarche decreased by 2.8 years, from 16.5 to 13.7, over an approximate 40-year time interval. This rapid decrease in age at menarche may partly be due to better nutrition and living standards reflected by the improved socioeconomic standards experienced in China over the past few decades. To test this hypothesis, a number of determinants of age at menarche were assessed; year of birth, literacy status, county of residence, amount of physical labour, general health status, pesticide exposure before age at menarche, and drinking water source were all found to be associated with age at menarche.

    Background The purpose of this study is to describe the prevalence of overweight, general obesity, and abdominal obesity and examine their associations with socioeconomic status in a rural Chinese adult population. Methods This cross-sectional study was performed on 15,236 participants ≥ 35 years of age (6,313 men [41.4%] and 8,923 women [58.6%]). Each participant’s weight, height, waist circumference (WC), and hipline circumference (HC) were measured, and demographic and socioeconomic data were collected using questionnaires. Results The mean body mass index (BMI) values were 23.31 ± 2.96 and 23.89 ± 3.23 kg m-2 and the mean WC values were 79.13 ± 8.43 and 79.54 ± 8.27 cm for men and women, respectively. The age-standardized prevalence rates of overweight (BMI ≥ 24.0 kg m-2), general obesity (BMI ≥ 28.0 kg m-2), and abdominal obesity (WC ≥ 85 cm for men and ≥ 80 cm for women) were 32.0%, 6.7%, and 27.0% for men and 35.1%, 9.7%, and 48.3% for women, respectively. All gender differences were statistically significant (p obesity slowly decreased among men but sharply increased among women as age increased (p obesity and abdominal obesity among women but positively associated with abdominal obesity among men. No significant correlation was found between obesity and income. Conclusions These results suggest a high prevalence of obesity which might differ by gender and age, and an inverse association among women and a mixed association among men noted between education and obesity in our locality. Preventive and therapeutic programs are warranted to control this serious public health problem. The gender-specific characteristics of populations at high-risk of developing obesity should be taken into consideration when designing interventional programs. PMID:24224024

    The literature on the economic and fiscal impacts of in-migrating retirees on rural communities tends to concentrate on the younger, more affluent newly retired. This article addresses an issue not systematically addressed: the impacts on communities as these retirees age. Households that vary by age have different income levels and expenditure patterns. A county-level, conjoined input-output/econometrics simulation model is used to assess the impacts of an aging rural population. As hypothesized, the magnitude and nature of impacts is in direct proportion to relative household size and income level. The increased local government expenditures are covered by the increased revenues, even as retirees age.

    The number of smokers in Chinese rural areas is more than 200 million, which is twice that in cities. It is very significant to carry out tobacco control interventions in rural areas. We performed this community intervention study to evaluate the efficacy of village-based health education of tobacco control on the male current smoking rate in rural areas. The population of this study was the males above 15 years old from 6 villages in rural areas. The villages were randomly assigned to intervention group or control group (3 villages in each group). Self-designed smoking questionnaire was applied. The intervention group received the village-based health education of tobacco control for one year. The primary outcome measurement was the male current smoking rate. In the baseline investigation, completed surveys were returned by 814 male residents from the control group and 831 male residents from the intervention group. The male current smoking rate in the control group and the intervention group was 61.2% and 58.5%, respectively, before intervention. There was no significant difference between these two groups (P>0.05). After one-year intervention, the current smoking rate in the intervention group (51.2%) was significantly lower than that in the control group (62.8%) (Pareas, which could be a suitable and feasible way for tobacco control in the Chinese rural areas.

    Full Text Available OBJECTIVES: The objective of this study was to examine, first, the relationship of having a rural vs. urban background with suicidal ideation in Chinese college students, and second, whether a potential relationship was mediated by depression. METHODS: A survey was conducted among 1,145 undergraduate students at a university in China. Suicidal ideation and depressive symptoms were measured by the revised Hopkins' Symptom checklist (SCL-90-R. Associations between rural vs. urban background, depression and suicidal ideation were estimated by multivariable linear regression-based β coefficients, logistic regression-based odds ratios (ORs, and corresponding 95% confidence intervals (CIs. The magnitude of indirect effect and bias-corrected 95% CIs were obtained through bootstrap techniques. RESULTS: Rural background was positively associated with depression, which was in turn associated with suicidal ideation. The OR for rural status and suicidal ideation equaled 2.15 (95% CI = 1.36-3.41. This OR was slightly, though significantly (p<0.05 attenuated by additional adjustment for depressive symptoms (OR = 1.99, 95% CI = 1.15-3.44. CONCLUSION: Having a rural background is a determinant of suicidal ideation in Chinese college students. Depression may only marginally mediate this association.

    To examine the incidence of obesity and its modifiable risk factors in Chinese adults aged 35-74 years. A total of 27 020 participants aged 35 to 74 years from two prospective cohort studies in China were followed up in the years of 2007 and 2008. Obesity and overweight were defined as body mass index ≥ 28.0, and 24.0-27.9 kg/m(2), respectively. Relative risks of obesity for risk factors were computed by using logistic regression. The annual incidence rates of obesity and overweight were 6.97 ‰ and 24.83 ‰ in Chinese adults aged 35-74 years, respectively. Women had a higher incidence of obesity than men (7.74 ‰ vs. 6.10 ‰). Participants in northern China had a higher incidence than those in southern (9.29 ‰ vs. 5.10 ‰) part of the country. Adults in rural had a higher incidence than those in urban (7.28 ‰ vs. 6.52 ‰). After adjusting for the baseline variables, such as gender, age, geographic region, degree of urbanization, the relative risk for obesity was 0.82 (95% CI:0.68-0.99) for participants with ≥ 12 years' education, compared with those risk of incidence of obesity. Participants who consumed milk and moderate amount of fruits, would show a lower risk of obesity. The incidence of obesity was 6.97 ‰ in Chinese middle and older adults. Our results underscored that the promotion of healthy lifestyle which include issues as increasing physical activity, consuming moderate amount of fruits and milk but less red meat, drinking less scented tea etc, could play key roles in obesity prevention and control among the Chinese adults, especially among people with low education level or with middle income.

    Poor sleep quality is an important symptom of many medical or psychiatric disorders. However, the impact of cooking oil fumes (COFs) on sleep quality has not been studied. This population-based cross-sectional study was conducted to examine the association between COFs of Chinese household cooking and sleep quality. Individual sleep quality assessment was completed in 2197 participants with an average age of 37.52 years, through Pittsburgh Sleep Quality Index (PSQI). Information about their cooking practice were also collected by self-reported questionnaire. As an internal biomarker of COFs, urinary 1-hydroxypyrene (1-HOP) (n = 562) was further measured using high-performance liquid chromatography. Binary logistic regression models were performed to evaluate the association between exposure to COFs and individual sleep quality. We found that, subjective poor kitchen ventilation, preheating oil to smoking, and cooking for over 30 minutes were positively associated with overall poor sleep quality (global PSQI score >5) [odds ratio (OR) = 1.75, 95% confidence interval (CI) = 1.43-2.16; 1.25, (1.03-1.52); 1.42, (1.15-1.76), respectively]. After adjusting for potential confounders, subjective poor kitchen ventilation still tend to increase the risk of long sleep latency, sleep disturbances, and daytime dysfunction [OR = 1.37, 95% CI = 1.09-1.73; 1.91, (1.39-2.61); 1.54, (1.23-1.93), respectively]. Similar results were observed in participants who preheated oil to smoking [OR = 1.36, 95% CI = 1.08-1.72; 1.55, (1.14-2.14); 1.25, (1.02-1.55), respectively] and cooked for over 30 minutes [OR = 1.34, 95% CI = 1.05-1.72; 1.46, (1.03-2.06); 1.36, (1.08-1.72), respectively]. Furthermore, high urinary 1-HOP level was also positively associated with overall poor sleep quality (OR = 2.30, 95% CI = 1.31-4.05). The results indicated that exposure to COFs from Chinese household cooking may be a risk factor for poor sleep quality among middle-aged Chinese

    Chinese liquor aroma components were characterized during the aging process using gas chromatography (GC). Principal component and cluster analysis (PCA, CA) were used to discriminate the Chinese liquor age which has a great economic value. Of a total of 21 major aroma components identified and quantified, 13 components which included several acids, alcohols, esters, aldehydes and furans decreased significantly in the first year of aging, maintained the same levels (p > 0.05) for next three years and decreased again (p process. Results of PCA and CA demonstrated that young liquor (fresh) and aged liquors were well separated from each other, which is in consistent with the evolution of aroma components along with the aging process. These findings provide a quantitative basis for discriminating the Chinese liquor age and a scientific basis for further research on elucidating the liquor aging process, and a possible tool to guard against counterfeit and defective products.

    Anti-aging Chinese medicines have been used in traditional beverages to promote health and prevent diseases. Interestingly, these functional beverages may be used differently between men and women, reflecting the "yin-yang" philosophy of Chinese medicine. Modern studies have revealed that some dietary natural products can slow aging in model organisms, and functional beverages containing such products have recently emerged in Chinese market, challenging the dominance of traditional functional beverages. Here we summarize both traditional anti-aging herbs and modern natural dietary compounds currently used in functional beverages in China, and also briefly outline the underlying mechanisms of the beverages in slowing aging process.

    This qualitative study critically explores the barriers experienced by diverse rural community stakeholders in facilitating environments that enable age-friendly social participation. Twenty-six semi-structured interviews were conducted across two rural Australian communities with stakeholders from local government, health, social care, and community organizations. Findings identify that rural community stakeholders face significant difficulties in securing resources for groups and activities catering to older adults, which subsequently impacts their capacity to undertake outreach to older adults. However, in discussing these issues, questions were raised in relation to whose responsibility it is to provide resources for community groups and organizations providing social initiatives and whose responsibility it is to engage isolated seniors. These findings provide a much-needed critical perspective on current age-friendly research by acknowledging the responsibilities of various macro-level social structures-different community-level organizations, local government, and policy in fostering environments to enable participation of diverse rural older adults.

    Through a comparative appreciation of Chinese and Western poems about old age, the present article tends to present a general convey of the western and eastern poets' attitudes and feelings towards old age, which is an aspect of human culture. The main themes are almost the same: reminiscence (sweet or bitter), solitude,contentment, detachment, sorrow and sentiment. But the Western are more optimistic and admire youth, regard old age as a natural stage of life. The Chinese, more conservative and perfectionist, show much more respect to the old, and think more about the past unfulfilled.

    The purpose of this study is to provide reference data about estimating dental age from third molars of the western Chinese population for comparing with other populations and being applied to the age estimation of western Chinese juveniles and adolescents. A total of 2078 digital panoramic radiographs of 989 male and 1089 female Chinese subjects aged between 5 and 23 years were examined. The mineralization status of the third molars was assessed using the formation stages described by Demirjian et al. with two modifications. The results showed that the development of third molars in the western Chinese population was likely to begin at age 5 in both males and females. The third molars 28 and 48 showed significantly higher frequency in females than in males. The third molars 18 in the stage 1, 38 in the stages 1, A and G, and 48 in the stage H showed significantly older average age in females than in males. The Demirjian's stages C and D could be used as a reference stage to determine dichotomously whether a western Chinese is more likely to be under or above age 14 or 16, respectively. This study provided reference data for the age estimation of western Chinese juveniles and adolescents by the mineralization stages of the third molar. Apart from forensic age determination in living subjects, the presented reference data can also be used for age estimations of unidentified corpses and skeletons.

    Full Text Available Data insufficiency has become the primary factor affecting research on income disparity in China. To resolve this issue, this paper explores Chinese income distribution and income inequality using distribution functions. First, it examines 20 sets of grouped data on family income between 2005 and 2012 by the China Yearbook of Household Surveys, 2013, and compares the fitting effects of eight distribution functions. The results show that the generalized beta distribution of the second kind has a high fitting to the income distribution of urban and rural residents in China. Next, these results are used to calculate the Chinese Gini ratio, which is then compared with the findings of relevant studies. Finally, this paper discusses the influence of urbanization on income inequality in China and suggests that accelerating urbanization can play an important role in narrowing the income gap of Chinese residents.

    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.

  4. Aging population in change – a crucial challenge for structurally weak rural areas in Austria

    2014-03-01

    Full Text Available Besides population decline, structurally weak rural areas in Austria face a new challenge related to demographic change: the increasing heterogeneity of their aging population. From the example of the so-called ‘best agers’ - comprising people aged 55 to 65 years - this contribution makes visible patterns and consequences of growing individualized spatial behaviour and spatial perception. Furthermore, contradictions between claims, wishes and expectations and actual engagement and commitment to their residential rural municipalities are being pointed out. These empirically-based facts are rounded off by considerations on the best agers’ future migration-behaviour and the challenges for spatial planning at the municipal level.

    Full Text Available This study compared the extractability of Cd, Cu, Ni, Pb, and Zn by 8 extraction protocols for 22 representative rural soils in Taiwan and correlated the extractable amounts of the metals with their uptake by Chinese cabbage for developing an empirical model to predict metal phytoavailability based on soil properties. Chemical agents in these protocols included dilute acids, neutral salts, and chelating agents, in addition to water and the Rhizon soil solution sampler. The highest concentrations of extractable metals were observed in the HCl extraction and the lowest in the Rhizon sampling method. The linear correlation coefficients between extractable metals in soil pools and metals in shoots were higher than those in roots. Correlations between extractable metal concentrations and soil properties were variable; soil pH, clay content, total metal content, and extractable metal concentration were considered together to simulate their combined effects on crop uptake by an empirical model. This combination improved the correlations to different extents for different extraction methods, particularly for Pb, for which the extractable amounts with any extraction protocol did not correlate with crop uptake by simple correlation analysis.

    Gender disparities in China are concentrated in poor rural areas and among poor households. The difference in intelligence between boys and girls is less clear in rural China. The purpose of this paper was to assess sex differences in the intellectual function of early school-aged children in rural China. One thousand seven hundred forty four early school-aged offspring of women who had participated in a prenatal supplementation trial with different combinations of micronutrients and continued to reside in two rural counties in China were followed. We measured their Full-Scale IQ (FSIQ), Verbal Comprehension Index (VCI), Working Memory Index (WMI), Perceptual Reasoning Index (PRI) and Processing Speed Index (PSI) using the Wechsler Intelligence Scale for Children (WISC-IV). Multilevel analyses were used to assess sex differences in intellectual functioning in 7-10-year-old children in rural China. Boys' adjusted mean FSIQ score was 0.97 points higher (95% CI: -2.22 - 0.28) than that of girls. Girls obtained higher mean WMI and PSI scores, with 1.32 points (95% CI: 0.14 - 2.51) and 3.10 points (95% CI: 1.82-4.38) higher adjusted means, respectively. Boys' adjusted mean VCI and PRI scores were significantly higher than those of girls, and the mean differences were 2.44 points (95% CI: 0.95 - 3.94) and 3.68 points (95% CI: 2.36 - 5.01), respectively. There is no evidence to suggest sex differences in the general intelligence of early school-aged children in rural China. However, a difference in general intelligence between 10-year-old boys and girls was evident. Girls and boys in rural China tended to show different specific cognitive abilities.

    Full Text Available Objectives: The number of rural-to-urban migrant workers has been increasing rapidly in China over recent decades, but there is a scarcity of data on health-related quality of life (HRQOL and health service utilization among Chinese rural-to-urban migrant workers in comparison to local urban residents. We aimed to address this question. Methods: This was a cross-sectional study of 2315 rural-to-urban migrant workers and 2347 local urban residents in the Shenzhen-Dongguan economic zone (China in 2013. Outcomes included HRQOL (measured by Health Survey Short Form 36 and health service utilization (self-reported. Results: Compared to local urban residents, rural-to-urban migrant workers had lower scores in all domains of HRQOL, and were more likely to report chronic illnesses (9.2% vs. 6.0%, adjusted OR = 1.62, 95% CI 1.28–2.04 and recent two-week morbidity (21.3% vs. 5.0%, adjusted OR = 5.41, 95% CI 4.26–6.88. Among individuals who reported sickness in the recent two weeks, migrant workers were much less likely to see a doctor (32.7% vs. 66.7%, adjusted OR = 0.21, 95% CI 0.13–0.36. Conclusions: Chinese rural-to-urban migrant workers have lower HRQOL, much more frequent morbidity, but are also much less likely to see a doctor in times of sickness as compared to local urban residents, indicating the existence of significant unmet medical care needs in this population.

    The prevalence of first ejaculation emission (spermarche) in Chinese Han boys in 1995 was considered. The subjects were 86,744 Han boys 9 through 18 years randomly selected from 28 provinces. Median spermarcheal ages (MSAs) were 14.4 and 14.6 years for urban and rural boys, respectively, and 14.3, 14.6, and 14.7 years for the boys of 1st, 2nd, and 3rd socioeconomic classes, respectively. Two environmental factors, ecological and socioeconomic, had strong influence upon MSAs. Eight indicators of somatic growth and motor ability were compared between pre- and post-spermarcheal boys of the same age. Post-spermarcheal boys were advanced in body size, shape, and physiological function during early and middle puberty, but most of the difference disappeared by 16 years. Pre-spermarcheal boys in a given age group were more linear and had more potential for increasing leg length into late adolescence. Within an age group, post-spermarcheal boys had advanced performances in several tasks requiring endurance, strength, and power around the age of maximum growth, 13-15 years. At older ages, the groups did not differ.

    Full Text Available OBJECTIVE: This study examined the prevalence of impaired fasting glucose (IFG and diabetes and their associated factors in 17,184 Chinese hypertensive adults aged 45-75 years. METHODS: A cross-sectional investigation was carried out in a rural area of Lianyungang, China. Previously undiagnosed diabetes [fasting plasma glucose (FPG ≥ 7.0 mmol/l] and IFG (6.1-6.9 mmol/l were defined based on FPG concentration. Previously diagnosed diabetes was determined on the basis of self-report. Total diabetes included both previously diagnosed diabetes and previously undiagnosed diabetes. RESULTS: The prevalence of previously diagnosed diabetes, undiagnosed diabetes, and IFG were 3.4%, 9.8%, and 14.1%, respectively. About 74.2% of the participants with diabetes had not previously been diagnosed. In the multivariable logistic-regression model, older age, men, antihypertensive treatment, obesity (BMI ≥ 25 kg/m(2, abdominal obesity (waist circumference ≥ 90 cm for men and ≥ 80 cm for women, non-current smoking, a family history of diabetes, higher heart rate, lower physical activity levels, and inland residence (versus coastal were significantly associated with both total diabetes and previously undiagnosed diabetes. Furthermore, methylene- tetrahydrofolate reductase (MTHFR 677 TT genotype was an independent associated factor for total diabetes, and current alcohol drinking was an independent associated factor for previously undiagnosed diabetes. At the same time, older age, men, abdominal obesity, non-current smoking, current alcohol drinking, a family history of diabetes, higher heart rate, and inland residence (versus coastal were important independent associated factors for IFG. CONCLUSION: In conclusion, we found a high prevalence of diabetes in Chinese hypertensive adults. Furthermore, about three out of every four diabetic adults were undiagnosed. Our results suggest that population-level measures aimed at the prevention, identification (even if

    On the basis of clarifying and defining rural land transfer, the necessity of rural land transfer is analyzed. Land transfer is the necessity in terms of promoting agricultural scale operation and improving production efficiency; proving opportunities for narrowing urban and rural gap; realizing rural surplus labor transfer and facilitating urbanization. Major problems in the existing rural land transfer are analyzed:unclear laws and regulations and rural land transfer lacks relevant legal protection;rural social security system is imperfect and can not solve farmers’ worries after land transfer; farmers and local governments are restricted by traditional ideas and it is hard to carry out the land transfer policies; rural system construction is relatively backward and the rural land transfer market is immature. Countermeasures on the governmental behaviors in rural land transfer are put forward: stipulating relevant administrative laws and regulations and perfecting the political system of rural land transfer; perfecting rural social security system and solving farmers’ worries after land transfer; changing the ideas and working style of local officials and leading farmers to form the scientific land transfer outlook;and vigorously promoting the construction of system and positively cultivating rural land transfer market.

    Full Text Available BACKGROUND AND AIMS: Metabolic syndrome (MS is prevalent in recent years but few data is reported in the rural areas in China. The aim of this study was to examine MS prevalence and its risk factors among women in rural China. METHODS AND RESULTS: The Nantong Metabolic Syndrome Study (NMSS, a population based cross-sectional study, was conducted during 2007-2008 in Nantong, China. In person interviews, blood glucose and lipid measurements were completed for 13,505 female participants aged 18-74 years. The International Diabetes Federation (IDF, the US Third Report of the National Cholesterol Education Program, the Adult Treatment Panel (ATPIII and modified ATPIII for Asian population has determined three criteria of MS. These criteria for MS were used and compared in this study. The prevalence of MS was 22.0%, 16.9% and 23.3% according to IDF, ATPIII and ATPIII-modified criteria, respectively. Levels of agreement of these criteria for MS were above 0.75. We found that vigorous-intensity of occupational physical activity was associated with a low prevalence of MS with OR of 0.76 (95% confidence interval (CI: 0.63-0.91. Rice wine drinkers (alcohol >12.8 g/day had about 34% low risks of developing MS with OR of 0.66 (95% CI: 0.48-0.91, compared with non-drinkers. Odds ratio of MS was 1.81 (95% CI: 1.15-2.84 in women who smoked more than 20 pack-years, compared to non-smokers. Odds ratio of MS was 1.56 (95% CI: 1.25-1.95 in women who had familial history of diseases, including hypertension, diabetes and stroke, compared to women without familial history of those diseases. CONCLUSION: MS is highly prevalent among women in rural China. Both physical activity and rice wine consumption play a protective role, while family history and smoking are risk factors in MS development. Educational programs should be established for promoting healthy lifestyles and appropriate interventions in rural China.

    China's nutrition transition is characterized by dramatic increases in overweight and cardiometabolic (CM) risk. The burden of obesity, CM risk factors and dietary intake among Chinese children were explored. Children 7-12 y old from the 2009 China Health and Nutrition Survey with available dietary intake data, anthropometry, blood pressure, and fasting blood samples were included (n=663). CM risk prevalence was calculated; logistic regression was used to investigate the association of nutrient intakes with CM risk, adjusting for age, gender, physical activity, area of residence and income. 14% of Chinese school-aged children and ~20% of those from urban areas and higher income households had overweight/obesity (pchildren and >=30% of those from urban areas and higher income households had impaired glucose/ HbA1c (pchildren had pre-dyslipidemia (i.e. at least one lipid measurement above borderline levels) and 21% of children had dyslipidemia. Approximately 30% of all children had energy intakes above requirements and 38% of them had excessive proportions of dietary fat and saturated fat. Children with higher intakes of total daily energy and total and added sugars had a greater likelihood of having impaired blood pressure and glucose/HbA1c. Childhood overweight and CM risk is prevalent in urban and rural areas of China and across different socioeconomic groups although disparities between classes still pervade. Several dietary factors such as sugars were significant correlates of CM risk.

    Particulate matter (PM) from different sources may differentially affect human health. Few studies have assessed the main sources of personal exposure to PM and their contributions among residents of developing countries, where pollution sources differ from those in higher-income settings. 116 daily (24-h) personal PM2.5 exposure samples were collected among 81 women cooking with biomass fuels in two villages in rural Yunnan, China. The PM samples were analyzed for mass and chemical composition, including water-soluble organic carbon (WSOC), black carbon (BC), and molecular markers. We found black carbon, n-alkanes and levoglucosan dominated the most abundant fractions of the total measured species and average personal PM2.5 exposure was higher in winter than that in summer in both villages. The composition data were then analyzed using a positive matrix factorization (PMF) receptor model to identify the main PM emission sources contributing to women's exposures and to assess their spatial (between villages) and seasonal variation in our study setting. The 6-factor solution provided reasonably stable profiles and was selected for further analysis. Our results show that rural Chinese women cooking with biomass fuels are exposed to a variety of sources. The identified factors include wood combustion (41.1%), a cooking source (35.6%), a mobile source (12.6%), plant waxes (6.7%), pyrolysis combustion (3.0%), and secondary organic aerosols (SOA; 1.0%). The mean source contributions of the mobile source, cooking source, and wood combustion factor to PM2.5 exposure were significantly different between women living in the two study villages, whereas the mean SOA, wood combustion, and plant waxes factors differed seasonally. There was no relationship between source contributions and questionnaire-based measurements of source-specific exposures, implying that the impacts of source contributions on exposure are affected by complex spatial, temporal and behavioral patterns

    Fate control has been often misconceptualized as a superstitious belief and overlooked in health psychology. It is not known how this cultural belief might impact the well-being of Chinese people living with HIV. This study examined the protective role of fate control for well-being and the potential mediation effect of resilience. Participants in this study were rural patients who contracted HIV via commercial blood donation. In this cross-sectional survey, 250 participants completed measures of fate control, well-being, and resilience. The results showed that fate control and resilience were positively associated with well-being. Resilience mediated the association between fate control and well-being. Our findings provide insight into the adaptive function of fate control as a cognitive defensive mechanism and highlight the need to incorporate this cultural belief in developing culturally sensitive intervention programs for resilience enhancement tailored for this understudied population infected with HIV living in rural China.

    This study makes an integrated investigation of how subjective well-being is associated with income, personal concerns, and societal evaluations and how these social and psychological correlates of subjective well-being are contextualized within a country. Data used for the empirical analysis come from a nationally representative sample survey conducted in China in 2009. It is found that subjective well-being is independently linked to income, personal concerns, and societal evaluations. Comparisons of urban and rural Chinese further reveal that income, structural attributions of inequality, and evaluations of governance are related to subjective well-being among both groups. Nevertheless, different sets of other evaluative correlates of subjective well-being between urban and rural people stand out, which is conjectured to be related to the long-time institutional, economic, and social segmentation of the two groups. This study has contributed to both the subjective well-being theories and the understanding of the consequences of social inequality.

    Full Text Available Despite increasing recognition of the role nutrition plays in the health of current and future generations, many women struggle to eat healthy. We used the PhotoVoice method to engage 10 rural women in identifying perceived barriers and facilitators to healthy eating in their homes and community. They took 354 photographs, selected and wrote captions for 62 images, and explored influential factors through group conversation. Using field notes and participant-generated captions, the research team categorized images into factors at the individual, relational, community/organizational, and societal levels of a socioecological model. Barriers included limited time, exposure to marketing, and the high cost of food. Facilitators included preparing food in advance and support from non-partners; opportunities to hunt, forage, and garden were also facilitators, which may be amplified in this rural environment. Nutritional interventions for rural women of childbearing age should be multi-component and focus on removing barriers at multiple socioecological levels.

    Chinese liquor aroma components were characterized during the aging process using gas chromatography (GC). Principal component and cluster analysis (PCA, CA) were used to discriminate the Chinese liquor age which has a great economic value. Of a total of 21 major aroma components identified and quantified, 13 components which included several acids, alcohols, esters, aldehydes and furans decreased significantly in the first year of aging, maintained the same levels (p > 0.05) for next three years and decreased again (p < 0.05) in the fifth year. On the contrary, a significant increase was observed in propionic acid, furfural and phenylethanol. Ethyl lactate was found to be the most stable aroma component during aging process. Results of PCA and CA demonstrated that young liquor (fresh) and aged liquors were well separated from each other, which is in consistent with the evolution of aroma components along with the aging process. These findings provide a quantitative basis for discriminating the Chinese liquor age and a scientific basis for further research on elucidating the liquor aging process, and a possible tool to guard against counterfeit and defective products.

    Full Text Available Abstract Background Education is one of the key elements in the promotion of a thorough paradigm for active aging. The aim of this study is to analyze factors that contribute the empowerment of older adults in a rural Mexican community and, thus, promote active aging. Methods The study was conducted in a rural Mexican community (Valle del Mezquital, based on an action-research paradigm. One hundred and fifty-five elderly subjects with elementary school education participated in a formal training program promoting gerontological development and health education. Participants in turn became coordinators of mutual-help groups (gerontological nucleus in Mexico. In-depth interviews were carried out to assess the empowerment after training for active aging. Results It was found that there was an increasing feeling of empowerment, creativity and self-fulfillment among participants. Among the main factors that positively influenced training of the elderly toward active aging were the teaching of gerontology topics themselves; besides, their motivation, the self-esteem, the increased undertaking of responsibility, the feeling of belonging to the group, and the sharing of information based on personal experience and on gerontological knowledge. Conclusion The main factors that contribute to empowerment of older adults in a rural Mexican community for participate in active aging programs are the training and teaching of gerontology topics themselves; besides, their interest, experience and involvement.

    Full Text Available A positive image of elderly people is found to be contributive to successful ageing. This paper reports a study that aims at revising and validating Image of Ageing Scale in a modern Chinese context and finding out how socio-demographic factors have impacted the latter's perception of the image of ageing. Confirmatory factor analysis supported the five-factor model suggested from exploratory factor analysis which produced good psychometric properties. Based on the two-cluster solution from the two-step cluster analysis on the image of ageing, results of both the Chi-square and the one-way ANOVA tests confirmed that age, residence location, marital status, working status, living arrangement, neighborhood relationships, illness and daily activity were significant predictors of elders' image of ageing. Logistic results further indicated that some predictors were not statistically significant in the multivariate analysis, whilst being urban, lonely, suffering from severe chronic illnesses, and showing little interests in daily activities, were identified as potent factors resulting in a negative image of ageing. Other than suggesting the Revised Chinese Version of the Image of Ageing Scale (IAS-C could be used in a Chinese society, our findings also led to a number of recommendations to promoting a positive image among the Chinese elderly.

    The aim of this study was to estimate the prevalence of dentine hypersensitivity (DH) among residents of rural China with dental fluorosis aged 30-69 years. A village located in northern China in which dental fluorosis was common was selected. Some 1250 residents with fluorosis ranging in age from 30 to 69 years completed a structured questionnaire and underwent clinical examination. Diagnosis of DH was based on the combination of the subject's self-evaluation and clinical examination. Dental fluorosis was evaluated using Dean's index (DI). In the village, the fluoride concentration in drinking water was 1.15-1.50 mg L(-1) . The community fluorosis index was 1.47, and 74 (9.7%) of the participants with dental fluorosis were diagnosed with DH. There was no significant difference between men and women. DH was most commonly observed in the lower incisors, and the most common cause of DH was cold stimulation. Logistic regression analysis showed acid reflux to be the only risk factor for DH in the current study. Among subjects with DH, none took treatment measures, visited a hospital or clinic, or used antisensitivity toothpaste. The prevalence of DH in the selected subjects with dental fluorosis was 9.7%. Acid reflux was found to be a risk factor for DH in the current study. © 2014 John Wiley & Sons Ltd.

    2000-01-01

    Objective To determine lactose metabolism and lactase activity in Chinese children of different ages, prevalence of lactase deficiency (LD), and lactose intolerance (LI). Methods All 1168 healthy subjects between 3 and 13 years were recruited from schools in four large cities in China. They were screened by a 25 g lactose tolerance test.Some subjecls were challenged with .50 g milk powder on different days. Both indicators,the expiratory H2 concentration and intolerance symptoms, were analyzed. Results LD occurred in 38.5% of children in the 3-5 year age group, and 87% of the 7-8 year and 11-13 year old groups. The age of occurrence for LD may be at 7-8 years among Chinese children. The prevalence of LI among Chinese children was 12.2% alage 3-5 years, 33.1% at age 7-8 years, and 30.5% al age 11-13 years, respectively. Conclusion The results demonstrate that LD is very common in Chinese children from these four cities. LD and LI have a dose dependent response: lactose absorption and symptorms are based on lactase activity. The relationship between breast feeding history (or the history of cow milk intake) and lactase activity among Chinese children has not been established.

    Full Text Available In this study, we have a study on the exploitation and utilization of traditional food safety and Chinese medicine resources in rural areas based on the survey of Tongcheng Anhui. There are a large variety and effectiveness of Traditional Chinese Medicine (TCM resources in vast rural areas and they are the material basis for the development of TCM cause and research of TCM products. For a long time, however, because of various objective and subjective factors such as lacking of due attention to development and utilization of the resources of TCM, the cause of traditional Chinese medicine in rural areas are lack of development potential. By selecting a representative sample of rural Tongcheng in Anhui and on the basis of investigation on development and utilization of local traditional Chinese medicine resources, we should analyze current problems of development and utilization of existing rural medicine resource and propose suggestions from the aspects of government and farmers research. In this way, we can provide a reference to the motherland researchers and workers of the pharmaceutical industry.

    2013-08-01

    This paper extends the burgeoning interest in emotion, health and place by investigating the emotionally complex experiences of aging and care in rural settings. Featuring a thematic analysis of 44 semi-structured interviews and two focus groups with older people and their carers in rural Ontario (Canada) we examine the importance and implications of emotions within and across multiple scales at which care relationships, expectations and responsibilities are negotiated. With the aim of broadening the discussion surrounding geographical dimensions of ethical care, our approach draws on feminist care ethics to understand the multifaceted ways in which emotions shape and are shaped by experiences of aging and caring at the interpersonal, household and community scales. The findings reveal how emotions are central, yet often-overlooked and even hidden within care relationships among older rural people and their carers. We argue that ethical care is contingent on recognizing and valuing the situated emotions involved in doing care work, sustaining care relationships and asking for care. In doing so, we demonstrate how qualitative research on the emotional geographies of care can contribute to the development of informed policies that are contextually sensitive and, ultimately, have the potential to build more ethical rural conditions of care.

To examine a possible relationship between linear growth and gut inflammation, we compared fecal calprotectin levels in 6 month old infants from poor rural vs affluent urban families. Methods The project was a cross-sectional comparison of FC from rural and urban populations in China. The relationship between length-for-age Z-score (LAZ and FC concentrations were also compared. Single fecal samples were assayed for FC using EK-CAL ELISA kits. Results The age of subjects for both locations was 6.1 ± 0.2 mo; all were apparently healthy. The mean ± SD of the LAZ for the rural and urban infants were −0.6 ± 0.9 and 0.4 ± 0.9, respectively. FC had a non-normal distribution. The median FC of 420.9 and 140.1 μg/g for rural and urban infants, respectively, were significantly different (P  Conclusion FC levels were significantly elevated in the rural infants and high concentrations accounted for approximately one-third of the low LAZ scores of these infants.

    This study had three purposes: (a) to compare the prevalence of boys' and girls' gender-atypical behaviors (GABs) in a sample of Chinese school-aged children, (b) to examine the developmental pattern of GABs in Chinese boys and girls over the age range in question (6-12 years), and (c) to test the effects of being an only child on children's GAB expression. Parents of 486 boys and 417 girls completed a Child Play Behavior and Activity Questionnaire (CPBAQ) in regard to their own children, and a demographic information sheet. The frequency distribution for each gender-related behavior was calculated. The associations between sex, age, and only-child status, and CPBAQ scale scores were examined. Although most GABs (by their very nature) were exhibited infrequently in Chinese children, it was found that girls displayed GABs more frequently than boys did. The prevalence of GABs rose for girls as they grew older, but fell slightly for boys. The expressions of GABs in only children did not differ from that in children with siblings. Possible effects of Chinese culture (including the current only-child policy) on children's GABs are discussed.

    Objective To describe hypertension screening and follow-up management among Chinese population aged 35 years and above within the primary health care system. Methods Data from 2010 China Chronic Disease and Risk Factor Surveillance System were used. We investigated previous hypertension diagnosis, screening, and follow-up assessments within the primary health care system. The prevalence of self-reported and criterion-based hypertension, screening rates, demographic and socioeconomic characteristics associated with screening, and patterns of follow-up assessments were recorded. The SAS software system was used for statistical analyses. Results About 17.1% reported a previous hypertension diagnosis. The rate difference between the two measures of prevalence was 27.2%. Among those without self-reported hypertension, 27.7%reported never visiting a clinic during the past 1 year and 60.4%of those attending a clinic reported ever being screened. Younger age group was associated with lower screening proportion;odds ratios of 35-, 45-, 55-, and≥65 years were 1.7 (95%CI:1.5-1.9), 1.5 (95%CI:1.3-1.7), 1.3 (95%CI:1.2-1.4), and 1.0, respectively. About 35.1% of the patients had undergone follow-up assessments four or more times during the past 1 year. Conclusion Majority of the Chinese population aged 35 years and above, particularly the less educated, elderly population, and rural residents were unaware of that they were suffering from hypertension. Most patients did not receive enough management services by the primary health care system. Thus, strengthening both the screening and follow-up management is needed.

In general, testosterone levels in males began to decline significantly after age 50. Significant ethnic differences in total, free and non-SHBG bound fraction estradiol levels were observed in the 20-29 and 50-59 age groups (p<0.05. The estradiol levels of Malay men decreased as they aged, but they increased for Chinese men starting at age 40. CONCLUSIONS: Small but significant differences in testosterone levels existed between Malay and Chinese males. Significant age and race differences existed in estradiol levels. These differences might contribute to the ethnic group differences in diseases related to sex hormones, which other studies have found in Malaysia.

    Full Text Available OBJECTIVES: Variations in the prevalence of sex-hormone-related diseases have been observed between Asian ethnic groups living in the same country; however, available data concerning their sex hormone levels are limited. The present study aimed to determine the influence of ethnicity and age on the sex hormone levels of Malay and Chinese men in Malaysia. METHODS: A total of 547 males of Malay and Chinese ethnicity residing in the Klang Valley Malaysia underwent a detailed screening, and their blood was collected for sex hormones analyses. RESULTS: Testosterone levels were normally distributed in the men (total, free and non-sex hormone-binding globulin (SHBG bound fractions, and significant ethnic differences were observed (p<0.05; however, the effect size was small. In general, testosterone levels in males began to decline significantly after age 50.

    Based on the characteristics of urban-rural dual economic structure in China,we build a dynamic endogenous urban-rural dual economic model closely linked to China’s reality,and carry out mathematical economics analysis of optimized conditions for urban and rural sectors. The main results show that:(i) The labor growth rate of urban-rural sectors must be greater than the time discount rate,or else there would be a vicious cycle of diminishing returns in the sectors;(ii) The accumulation rate of physical capital and human capital of urban-rural sectors,and the rate of technological progress,need to be greater than the corresponding depreciation rate plus the time discount rate,otherwise there would be a vicious cycle of diminishing returns in the sectors;(iii) The low accumulation rate in the rural sector,and the occurrence of labor outflow,human capital loss and lack of investment,will expand income gap between urban and rural areas,which is a reason for solidification of urban-rural dual economic structure.

    To date, accurate reports about the prevalence of high normal blood pressure (BP) and hypertension among Chinese adolescents have been rare. We examine the sex-specific and age-specific prevalence of high normal BP and hypertension, and the associated risk factors among multi-ethnic Chinese adolescents from a large and representative sample. 29,997 adolescents aged 8-18 years old received blood pressure measurement on one clinical visit. The overall prevalence was 4.15% for hypertension (4.73% for boys and 3.62% for girls) and 29.85% for high normal BP (33.40% for boys and 26.65% for girls). The odds ratios (ORs) increased with age, but the absolute changes of ORs were significantly different between boys and girls. Compared with that of the Han counterparts, the risk of high normal BP was 1.960-fold, 1.283-fold and 1.618-fold for Yi boys, Mongolian boys and Yi girls, respectively, whereas the OR was 0.440 for Tibetan boys, 0.492 for Tibetan girls and 0.794 for Korean girls. Compared with those of normal weight, overweight and obese adolescents had significantly increased risk of high normal BP (OR = 3.377 for obese boys and OR = 2.009 for overweight boys; OR = 2.865 for obese girls and OR = 1.738 for overweight girls). Rural adolescents had a higher risk of hypertension than those living in urban areas. The prevalence of high normal BP and hypertension was high in Chinese adolescents. Age, ethnicity, obesity, overweight, abnormal waist circumference, family history of cardiovascular diseases and dwelling at rural districts were significantly associated with pediatric high normal BP or hypertension.

    Full Text Available Abstract Background Childhood and adolescence are critical periods of habit formation with substantial tracking of lifestyle and cardiovascular risk into adulthood. There are various guidelines on recommended levels of physical activity in youth of school-age. Despite the epidemic of obesity and diabetes in China, there is a paucity of data in this regard in Chinese youth. We examined the association of self-reported level of physical activity and cardiovascular risk in Hong Kong Chinese youth of school-age. Methods This was a cross-sectional study conducted in 2007-8 in a school setting with 2119 Hong Kong Chinese youth aged 6-20 years. Physical activity level was assessed using a validated questionnaire, CUHK-PARCY (The Chinese University of Hong Kong: Physical Activity Rating for Children and Youth. A summary risk score comprising of waist circumference, blood pressure, fasting plasma glucose and lipids was constructed to quantify cardiovascular risk. Results In this cohort, 21.5% reported high level of physical activity with boys being more active than girls (32.1% versus 14.1%, p Conclusion Self-reported level of physical activity is associated with cardiovascular risk factors in Chinese youth after adjusting for sex and pubertal stage.

    Using cross-sectional data from rural-to-urban migrant adolescents in urban areas of Beijing, China, we examined the mediating effects of social support (i.e. teacher support and classmate support) in the relationship between perceived discrimination (PD) and antisocial behaviour (ASB) among Chinese migrant adolescents. Participants were 897 adolescents (459 boys and 438 girls, mean age = 13.34 years) from four migrant schools (68.8%) and four public schools (31.2%). Participants completed self-report questionnaires concerning PD, ASB, teacher support and classmate support. Results indicated that Chinese migrant adolescents who perceived more discrimination were more likely to engage in ASB. Teacher support partially mediated the relationship between PD and ASB. Gender moderated this mediational relationship, such that teacher support exerted a mediating role among girls, but not boys. The findings suggest that reductions in teacher support may partially account for the effect of PD on ASB among Chinese migrant adolescents girls. © 2016 International Union of Psychological Science.

    Full Text Available Anaemia is a major public health problem in India. Although nearly three quarters of the Indian population live in rural areas, the epidemiology of anaemia in rural settings is not well known. We performed a retrospective observational study using routine clinical data from patients attending the out-patient clinics of a rural hospital in India from June 2011 to August 2014. The study included 73,795 determinations of haemoglobin. 49.5% of patients were female. The median haemoglobin concentration was 11.3 g/dL (interquartile range (IQR, 9.8–12.4 in females and 12.5 g/dL (IQR, 10.6–14.2 in males. Anaemia was present in the majority of children <10 years, women after puberty, and older adults. Children <5 years had the highest prevalence of anaemia, especially children aged 1-2 years. The high proportion of microcytic anaemia and the fact that gender differences were only seen after the menarche period in women suggest that iron deficiency was the main cause of anaemia. However, the prevalence of normocytic anaemia increased with age. The results of this study can be used by public health programmes to design target interventions aimed at reducing the huge burden of anaemia in India. Further studies are needed to clarify the aetiology of anaemia among older adults.

    Age-friendly initiatives are increasingly promoted as a policy solution to healthy aging, The primary objective of this article was to examine older adults' and key stakeholders' perceptions of the factors that either help or hinder a community from becoming age-friendly in the context of rural Manitoba, a Canadian prairie province. Twenty-four older adults and 17 key informants completed a qualitative interview. The findings show that contextual factors including size, location, demographic composition, ability to secure investments, and leadership influence rural communities' ability to become age-friendly. Government must consider the challenges these communities face in becoming more age-friendly and develop strategies to support communities.

    Full Text Available Abstract Background Self-rated health (SRH has been demonstrated to be an accurate reflection of a person's health and a valid predictor of incident mortality and chronic morbidity. We aimed to evaluate the distribution and factors associated with SRH and its association with biomarkers of cardio-metabolic diseases among middle-aged and elderly Chinese. Methods Survey of 1,458 men and 1,831 women aged 50 to 70 years, conducted in one urban and two rural areas of Beijing and Shanghai in 2005. SRH status was measured and categorized as good (very good and good vs. not good (fair, poor and very poor. Determinants of SRH and associations with biomarkers of cardio-metabolic diseases were evaluated using logistic regression. Results Thirty two percent of participants reported good SRH. Males and rural residents tended to report good SRH. After adjusting for potential confounders, residence, physical activity, employment status, sleep quality and presence of diabetes, cardiovascular disease, and depression were the main determinants of SRH. Those free from cardiovascular disease (OR 3.68; 95%CI 2.39; 5.66, rural residents (OR 1.89; 95% CI 1.47; 2.43, non-depressed participants (OR 2.50; 95% CI 1.67; 3.73 and those with good sleep quality (OR 2.95; 95% CI 2.22; 3.91 had almost twice or over the chance of reporting good SRH compared to their counterparts. There were significant associations -and trend- between SRH and levels of inflammatory markers, insulin levels and insulin resistance. Conclusion Only one third of middle-aged and elderly Chinese assessed their health status as good or very good. Although further longitudinal studies are required to confirm our findings, interventions targeting social inequalities, lifestyle patterns might not only contribute to prevent chronic morbidity but as well to improve populations' perceived health.

    In China, the gender ratio of suicide rates did not match the Western patterns, which was higher for females than males. However, the rural men were at relatively high risk of suicide in Liaoning province. Impulsivity was an important factor of suicide behaviors, but there was a lack of studies in China. This research aimed to study the relationship between impulsive personality traits and suicidal behavior among Chinese rural youths. Suicides were consecutively sampled from six randomly selected counties in Liaoning Province in China. Between 2005 and 2007, a total of 162 suicide victims were enrolled in the study along with 162 community controls matched for age, gender, and location. The psychological autopsy method was used to collect data from informants knowledgeable about the selected suicide victims and controls. The results showed the suicide victims in the study were more likely to demonstrate dysfunctional impulsivity and less likely to demonstrate functional impulsivity compared with the controls. Mental disorders, acute negative life events, and dysfunctional impulsivity contributed to the risk of suicide; educational and functional impulsivity were protective factors. Suicide prevention efforts in rural China may address impulsivity.

    Perceived facial age has been proposed as a biomarker of ageing with ‘looking young for one’s age' linked to physical and cognitive functioning and to increased survival for Caucasians. We have investigated the environmental and lifestyle factors associated with perceived facial ageing in Chinese women. Facial photographs were collected from 250 Chinese women, aged 25–70 years in Shanghai, China. Perceived facial age was determined and related to chronological age for each participant. Lifestyle and health information was collected by questionnaire. Bivariate analyses (controlling for chronological age) identified and quantified lifestyle variables associated with perceived facial age. Independent predictors of perceived age were identified by multivariate modelling. Factors which significantly associated with looking younger for one's chronological age included greater years of education (p<0.001), fewer household members (p = 0.027), menopausal status (p = 0.020), frequency of visiting one's doctor (p = 0.013), working indoors (p<0.001), spending less time in the sun (p = 0.015), moderate levels of physical activity (p = 0.004), higher frequency of teeth cleaning (p<0.001) and more frequent use of facial care products: cleanser (p<0.001); moisturiser (p = 0.016) or night cream (p = 0.016). Overall, 36.5% of the variation in the difference between perceived and chronological age could be explained by a combination of chronological age and 6 independent lifestyle variables. We have thus identified and quantified a number of factors associated with younger appearance in Chinese women. Presentation of these factors in the context of facial appearance could provide significant motivation for the adoption of a range of healthy behaviours at the level of both individuals and populations.

    Full Text Available Current research about old age during the Ancient Regime in Spain is insufficient. And the same is the case with women, despite the large number of studies about gender and family history in the past decades. Taking, as a starting point, the analysis of widow women which became heads of households, this paper aims to know which specific characteristics had those households during their old age, composition, size, typology and the tendency to solitude; which activities and livelihood they had, paying attention to those differences as an expression of inequality; and which mechanisms and social reproduction strategies they followed to deal with the effects of aging. This paper is geografically focused in a wide rural area of central-southern Spain and aims to review the assumption that single and widow women in preindustrial age had subordinted lives.

    The degree of the aging population in rural areas is higher than that in urban areas.The outflow of young labors from rural areas causes the rural“Empty Nest”phenomenon more serious.The sharply-rising of the rural aged dependency ratio not only puts a heavy financial burden on the economically backward rural areas,but also puts much pressure on the rural family care service.The concept and method of community care,which suits the rural social reality and the rural aged psychological condition and can effectively address the imbalance between supplying and demanding of rural aged care service,is conductive to covering the short-age and deficiency of the aged care in families and institutions.The Chinese national government,with the community care mode used for reference,has introduced a series of policies to promote the development of community care service,and despite all that,there still exist a list of problems on the road of the development of rural aged care service.%我国农村地区的老龄化程度高于城市,由于青壮年劳动力的大量流出,导致农村“空巢”现象严重,老年人口抚养比急剧上扬,不仅使经济落后的农村地区养老的经济负担更为沉重,而且给农村家庭养老照护服务带来了更大的压力。社区照顾的理念和方法有助于弥补家庭照顾和机构照顾的不足,适合农村地区的社会现实和农村老年人的心理,能够有效解决农村养老服务供给失衡的问题。我国政府借鉴社区照顾模式,出台了一系列推动社区养老服务发展的政策措施,取得了一定的成效,但是,农村养老服务仍然面临一系列的发展难题。

    To assess the impact of an intervention modifying dietary habits for the prevention of anaemia in rural India. Intervention study with data on anthropometric (weight, height) measurements, Hb and diet pattern. As per the cut-off for Hb in the government programme, women with Hb 11 g/dl formed the non-supplemented group. Settings Three villages near Pune city, Maharashtra, India. Rural non-pregnant women (n 317) of childbearing age (15-35 years). After 1 year of intervention, mean Hb increased (from 10.94 (sd 1.22) g/dl to 11.59 (sd 1.11) g/dl) significantly (P 50% of the meetings or repeating >50% of the recipes at home (0.45 g/dl) in the non-supplemented group and was smaller than that observed in the supplemented group. Consumption of green leafy vegetables more than twice weekly increased substantially from 44.7% to 60.6%, as did consumption of seasonal fruits. Logistic regression showed that women with lower participation in the intervention had three times higher risk (OR = 3.08; 95% CI 1.04, 9.13; P = 0.04) for no gain in Hb compared with those having high participation. Developing action programmes for improving nutritional awareness to enhance the consumption of Fe-rich foods has great potential for preventing anaemia in rural India.

    Anaemia is a major public health problem in India. Although nearly three quarters of the Indian population live in rural areas, the epidemiology of anaemia in rural settings is not well known. We performed a retrospective observational study using routine clinical data from patients attending the out-patient clinics of a rural hospital in India from June 2011 to August 2014. The study included 73,795 determinations of haemoglobin. 49.5% of patients were female. The median haemoglobin concentration was 11.3 g/dL (interquartile range (IQR), 9.8-12.4) in females and 12.5 g/dL (IQR, 10.6-14.2) in males. Anaemia was present in the majority of children older adults. Children iron deficiency was the main cause of anaemia. However, the prevalence of normocytic anaemia increased with age. The results of this study can be used by public health programmes to design target interventions aimed at reducing the huge burden of anaemia in India. Further studies are needed to clarify the aetiology of anaemia among older adults.

    Full Text Available OBJECTIVES: Prior evidence suggests geographic disparities in the effect of maternal education on child nutritional status between countries, between regions and between urban and rural areas. We postulated its effect would also vary by micro-geographic locations (indicated by mountain areas, plain areas and the edge areas in a Chinese minority area. METHODS: A cross-sectional study was conducted with a multistage random sample of 1474 school children aged 5-12 years in Guyuan, China. Child nutritional status was measured by height-for-age z scores (HAZ. Linear mixed models were used to examine its association with place of residence and maternal education. RESULTS: Micro-geographic disparities in child nutritional status and the level of socioeconomic composition were found. Children living in mountain areas had poorer nutritional status, even after adjusting for demographic (plain versus mountain, β = 0.16, P = 0.033; edge versus mountain, β = 0.29, P = 0.002 and socioeconomic factors (plain versus mountain, β = 0.12, P = 0.137; edge versus mountain, β = 0.25, P = 0.009. The disparities significantly widened with increasing years of mothers' schooling (maternal education*plain versus mountain: β = 0.06, P = 0.007; maternal education*edge versus mountain: β = 0.07, P = 0.005. Moreover, the association between maternal education and child nutrition was negative (β = -0.03, P = 0.056 in mountain areas but positive in plain areas (β = 0.02, P = 0.094 or in the edge areas (β = 0.04, P = 0.055. CONCLUSIONS: Micro-geographic disparities in child nutritional status increase with increasing level of maternal education and the effect of maternal education varies by micro-geographic locations, which exacerbates child health inequity. Educating rural girls alone is not sufficient; improving unfavorable conditions in mountain areas might make such investments more effective in promoting child health.

    The nature and characteristics of self-directed learning (SDL) by physicians has been transformed with the growth in digital, social, and mobile technologies (DSMTs). Although these technologies present opportunities for greater "just-in-time" information seeking, there are issues for ensuring effective and efficient usage to compliment one's repertoire for continuous learning. The purpose of this study was to explore the SDL experiences of rural physicians and the potential of DSMTs for supporting their continuing professional development (CPD). Semistructured interviews were conducted with a purposive sample of rural physicians. Interview data were transcribed verbatim and analyzed using NVivo analytical software and thematic analysis. Fourteen (N = 14) interviews were conducted and key thematic categories that emerged included key triggers, methods of undertaking SDL, barriers, and supports. Methods and resources for undertaking SDL have evolved considerably, and rural physicians report greater usage of mobile phones, tablets, and laptop computers for updating their knowledge and skills and in responding to patient questions/problems. Mobile technologies, and some social media, can serve as "triggers" in instigating SDL and a greater usage of DSMTs, particularly at "point of care," may result in higher levels of SDL. Social media is met with some scrutiny and ambivalence, mainly because of the "credibility" of information and risks associated with digital professionalism. DSMTs are growing in popularity as a key resource to support SDL for rural physicians. Mobile technologies are enabling greater "point-of-care" learning and more efficient information seeking. Effective use of DSMTs for SDL has implications for enhancing just-in-time learning and quality of care. Increasing use of DSMTs and their new effect on SDL raises the need for reflection on conceptualizations of the SDL process. The "digital age" has implications for our CPD credit systems and the roles

    Background Genetic mechanisms contribute to blood pressure regulation. This study investigated whether glutathione peroxidase (GPx-3) tag single nucleotide polymorphisms (SNPs) are associated with hypertension in the rural areas of Fuxin county, Liaoning province, China.Methods Indigenous Fuxin Han people participated, 523 unrelated hypertensives and 547 controls were recruited. All tag SNPs of GPx-3 gene were selected. We estimated SNP allele frequency in DNA pools with pyrosequencing.Results Before Bonferroni correction, C allele frequency for rs8177417 was significantly higher in hypertensives than those in controls (23.4% vs. 19.3%, P=0.014); T allele frequency for rs3828599 was significantly lower in hypertensives than those in controls (35.6% vs. 40.8%,P=0.009). However, when a Bonferroni correction for multiple testing was applied, only the polymorphisms rs3828599 of GPx-3 gene was associated with hypertension (P=0.045, OR: 0.833, 95%CI: 0.695-0.998).Conclusion The polymorphism of rs3828599 of GPx-3 gene might be associated with hypertension in rural Han Chinese from Fuxin, Liaoning.

    Currently, research in sexual behavior and awareness in female Chinese college students (FCCSs) is limited, particularly regarding the difference and the influencing factors between students from rural areas and urban areas. To fill the gap in available data, a cross-sectional study using anonymous questionnaires was conducted among 3193 female students from six universities located in Beijing, Shanghai, and Guangzhou, China, from February to June, 2013. Of the 2669 respondents, 20.6% and 20.9% of the students from urban and rural areas, respectively, reported being sexually experienced. The proportion of students who received safe-sex education prior to entering university from rural areas (22.4%, 134/598) was lower (P Sexual behavior has become increasingly common among FCCSs, including high-risk sexual behavior such as unprotected commercial sex. However, knowledge concerning human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) transmission and the risks is insufficient, particularly for those from rural areas, which is a challenge for HIV/AIDS control in China. The Chinese government should establish more specific HIV/AIDS prevention policies for Chinese young women, strengthen sex education, and continue to perform relevant research.

    Full Text Available To assess the influence of education on the performance of Chinese version of Montreal cognitive assessment (C-MoCA in relation to the mini-mental state examination (MMSE in detecting amnesic mild cognitive impairment (aMCI among rural-dwelling older people C-MoCA and MMSE was administered and diagnostic interviews were conducted among community-dwelling elderly in two villages in Beijing. The performance of C-MoCA and MMSE in detecting aMCI was evaluated by the area under the ROC curve (AUC. Effect size of education on variations in C-MoCA scores was estimated with general linear model. Among 172 study participants (24 cases of aMCI and 148 normal controls, the AUC of C-MoCA was 0.72 (95% CI = 0.62–0.81, cutoff = 20/21, compared to AUC of MMSE of 0.74 (95% CI = 0.64–0.84, cutoff = 26/27. The performance of both C-MoCA and MMSE was especially poorer among those with low (0–6 years education. After controlling for gender and age, education (η2 = 0.204 had a surpassing effect over aMCI diagnosis (η2 = 0.052 on variations in C-MoCA scores. Among rural older people, the MoCA showed modest accuracy and was no better than MMSE in detecting aMCI, especially in those with low education, due to the overwhelming effect of education relative to aMCI diagnosis on variations in C-MoCA performance.

    Approximately one billion adults worldwide are hypertensive and most aged 60 or above. Poor adherence with medication treatment is still one of the main causes of failure in achieving blood pressure control. Compared to younger individuals, aging perception may be the main factor influencing elders receiving preventive care. Some studies have investigated the impact of self-perceptions of aging on some preventive health behaviors including "followed the directions for taking prescription medications" in developed countries in the West. However, there is a scarcity of studies evaluating the self-perceptions of aging and its association with antihypertensive adherence among Chinese older adults. This study aimed to identify the association between aging perceptions and antihypertensive drug adherence among Chinese older adults. A cross-sectional investigation was conducted in wards and outpatient clinic of a University Hospital and communities in Suzhou, China. Older adults who were taking at least one antihypertensive drug currently were invited to complete a self-administered questionnaire, including basic socio-demographic and clinical information, self-reported medication adherence and self-perceptions of aging. From 585 old patients, 34.2 % was determined to have good medication adherence. Logistic regression analysis demonstrated that good adherence to antihypertensive agents was more common among those with lower scores on "timeline cyclical" (p = 0.004) and "identity" (p aging perceptions. Self-perceptions of aging, being significantly associated with medication adherence, are an important starting point when conducting intervention programmes for elder patients.

    Biomass energy sources are still popular in the rural areas of developing countries for cooking and space heating. Since the incomplete combustion of agricultural residues in home-made ranges might lead to both outdoor and indoor air pollution and cause potential health threat to the rural population, we monitored the ambient levels of 16 US EPA priority polycyclic aromatic hydrocarbons (PAHs) at a typical rural site. Ambient particulate PAH samples (PM2.5 and PM10) were taken during both cooking and non-cooking periods. Source emission monitoring was also conducted for both improved and tra- ditional cooking stoves used in the area. Ambient PAHs had a significant increase during the cooking periods and varied from 72.1 to 554.4 ng/m3. The highest total PAH levels were found during the supper cooking time, in which five- and six-ring species accounted for a large proportion. The observed PAH levels during cooking periods at this rural site were even higher than those in urban areas. A good correlation was found between the benzo[a]pyrene level and the total PAH concentration (r=0.98), making benzo[a]pyrene a potential molecular marker for PAH pollution in the rural areas, where bio- mass burning is typical. The profiles of the particulate PAHs in both ambient air and source emissions showed a high proportion of high molecular-mass PAHs. In addition, emission factors of 16 PAHs from an improved household stove were found to be significantly lower than those from traditional stoves used in China and in other Asian countries.

    Full Text Available OBJECTIVE: The causes of low back pain in China and Western countries are extremely different. We attempted to analyze the risk factors of low back pain in urban and rural patients under the dual economy with the simplified Chinese version of Roland-Morris disability questionnaire (SC-RMDQ to demonstrate that SC-RMDQ could evaluate patients with low back pain arising from different causes. METHODS: Roland-Morris disability questionnaire was translated into SCRMDQ according to international guidelines for questionnaire adaptation. In this study, causes of low back pain of 187 outpatients and inpatients (99 urban patients and 88 rural patients were analyzed. All patients underwent simplified Chinese version of Roland-Morris disability questionnaire (SC-RMDQ, simplified Chinese Oswestry disability index (SCODI and visual analogue scale (VAS. Reliability was tested using reproducibility (intraclass coefficient of correlation--ICC and internal consistency (Cronbach's alpha. Validity was tested using Pearson correlation analysis. RESULTS: The leading causes for low back pain were sedentariness (38.4% and vibration (18.1% in urban patients and waist bending (48.9% and spraining (25% in rural patients. Although causes of low back pain in the two groups of population were completely different, SCRMDQ had high internal consistency (Cronbach's α value of 0.874 in urban patients and 0.883 in rural patients and good reproducibility (ICC value of .952 in urban patients and 0.949 in rural patients, P<0.01. SCRMDQ also showed significant correlation with Simplified Chinese version of Oswestry disability index (SCODI and visual analogue scale (VAS in rural areas (SCRMDQ-SCODI r = 0.841; SCRMDQ-VAS: r = 0.685, P<0.01 and in urban areas (SCRMDQ-SCODI: r = 0.818, P<0.01; SCRMDQ-VAS: r = 0.666, P<0.01.

    A cross-sectional study was undertaken to investigate family planning (FP) practices and associated factors among reproductive-age married women. Data were collected by interviewing the 300 married women living in a rural area of Myanmar. The questionnaire had reliability coefficients ranging from .8 to .9. Results indicated that 73.3% of women performed FP, and contraceptive injection was the most common method. Significant associations were found with age 21 to 35 years (adjusted odds ratio [adj OR] = 3.748, 95% CI = 2.179-6.445), adequacy of income (adj OR = 2.520, 95% CI = 1.477-4.290), good attitude toward FP (adj OR = 0.386, 95% CI = 0.228-0.656), good support from health care providers (adj OR = 0.129, 95% CI = 0.054-0.313), good support from family (adj OR = 0.304, 95% CI = 0.163-0.565), good support from friends (adj OR = 0.344, 95% CI = 0.193-0.613), and FP practice. It is recommended that designing FP programs with peers and family involvement could increase the practice of FP among rural Myanmar women. © 2016 APJPH.

    Full Text Available Most of the needs of elders for support and assistance in the later stages of life are fulfilled by informal helpers. The position of a large number of older persons has become vulnerable due to which it cannot be taken for granted that their children will be able to look after them when they need care in old age, specially in view of the longer life span implying an extended period of dependency and higher costs to meet health and other needs. The condition of the rural elderly is even more pitiable, contrary to our beliefs, as availability, affordability and accessibility to medicare facilities are poor. We undertook the task of organizing a health camp in a rural set-up with the idea of implementing our concept of "preventive palliation" in which excellent palliative care was coupled with a pinch of prevention, like routine checks of blood pressure, routine physical check-ups, etc, so that any aberration can be detected early and necessary rectification measures can be implemented. These periods of routine check-ups can also be used to assess the psycho-social, cultural and emotional problems, if any. Such an approach, say every monthly, gives the elderly something to look forward to and ensures a high degree of customer satisfaction and greatly reduces the burden on the current health system. The challenges faced and the data obtained from this study were shocking. The elderly living in rural areas of the tribal state of Jharkhand suffer from poor physical and mental health, a factor which was rather unexpected in the Indian cultural system in the rural setting. Simple strategies like implementing routine health check ups with provision of "nutritious meal program" can go a long way in mitigating these problems in a cost-effective and simple manner. To make the government-based programs accessible and available to the end-users, participation of local bodies like NGOs is mandatory. Preventive palliation, a concept introduced by Kosish, is

    Full Text Available Abstract Background Early age at menarche is associated with increased risk of metabolic syndrome in both China and the West. However, little is known about the impact of age at menarche and metabolic syndrome in South Asian women, including those from low-income country, where age at menarche is also falling. The aim of the present study was to investigate whether age at menarche is inversely associated with metabolic syndrome in Bangladeshi women, who are mostly poor and have limited access to and or poor health care facilities. Methods This community-based cross-sectional study was performed using 1423 women aged between 15–75 years from rural Bangladesh in 2009 and 2010. Metabolic syndrome was defined according to standard NCEP-ATP III criteria. Logistic regression was used to estimate the association between age at menarche and metabolic syndrome, with adjustment of potential confounding variables, including age, education, marital status, tobacco users, use of contraceptives and number of pregnancies. Results Early onset of menarche (13 years was found to be associated with a higher prevalence of metabolic syndrome (odds ratio=1.55; 95 % confidence interval =1.05-2.30. Age at onset of menarche was also inversely associated with prevalence of high triglycerides (P for trend P for trend = 0.01, but positively associated with prevalence of high fasting blood glucose (P for trend =0.02. However, no significant association was found between age at menarche, high blood pressure and elevated waist circumference. Conclusion Early onset of menarche might promote or trigger development of metabolic syndrome. Thus, knowledge of the history of age at onset of menarche may be critical in identifying women at risk of developing metabolic syndrome and those likely to benefit the most from early interventions.

    To provide a better service for senior health care, we summarized screening studies of traditional Chinese anti-aging materia medica (TCAM). We collected and analyzed literature of TCAM screening studies using the lifespan test and animal models of aging from 1984 to 2012. We found 26 screening methods for TCAM, and 153 single herbs or active ingredients of TCAM that have been screened out during the past 28 years. The cell lifespan test, the fruit fly lifespan test, and D-galactose aging model were the most widely used and intensively studied screening methods. However, the method for establishing the D-galactose aging model needs to be standardized, and the D-galactose aging model cannot completely be a substitute for the normal aging mouse model. Great success has been achieved in screening studies in TCAM. To further improve screening studies in TCAM, we suggest that the D-galactose aging model be incorporated into the lifespan test in the New Drugs of Traditional Chinese Medicine Research Guide.

    2009-01-01

    Full Text Available This paper aims to demonstrate the advantages of adopting an ethnographic, actor interface approach to understanding the ongoing dynamics of rural development and policy intervention processes. It does so through the discussion of an EU-funded project orientated to introducing village-level forest-management practices in north-west China. The case highlights the ongoing everyday struggles over livelihoods and resources and focuses on the negotiations that take place between the various social actors involved. The case analysis is preceded by a broad-sweep overview of the rise of new ruralities and a discussion of the key elements of an actor interface analysis. The article concludes with a call for more cross-country and cross-regional studies of this kind.

    Full Text Available The 6-minute walk distance (6MWD is used as a measure of functional exercise capacity in clinical populations and research. Reference equations to predict 6MWD in different populations have been established, however, available equations for Chinese population are scarce. This study aimed to develop regression equations to predict the 6MWD for a Hong Kong Chinese population. Fifty-three healthy individuals (25 men, 28 women; mean age = 69.3 ± 6.5 years participated in this cross-sectional study. Each participant performed two 6-minute walk tests (6MWTs in accordance with a standard protocol. Heart rate (HR was continuously monitored throughout the 6MWTs and the maximum HR was recorded. Measurements from the 6MWT that resulted in the highest 6MWD were used for regression analysis. The mean 6MWD was 563 ± 62 m and was significantly correlated with age (r = −0.62, height (r = 0.39, and percentage of predicted maximal HR (%predHRmax; r = 0.50. A regression equation derived from the data showed that age, sex, and %predHRmax were independent contributors and together explained 65% of the variance in 6MWD. When HR was excluded, the equation explained 52% of the variance. Application of these equations to a Chinese population living in different parts of China warrants further investigation.

    Rare reports can be found about sex- and age-specific body composition survey among Chinese population. The aim of this study is to explore the change of sex-specific body compositions with aging among Chinese adolescents, adults and elders. In a large-scale population survey about physiological constants and health conditions, 75,714 subjects who aged from 8 to 80 completed body composition array. Body mass index (BMI), percentage body fat (PBF), water percentage of body weight (WPBW), water percentage of lean body mass (WPLBM), fat-free mass index (FFMI) and basic metabolic rate were examined with Biodynamics BI-310 body composition analyzer. General obesity is defined as BMI equal to or greater than 28 kg/m2. The prevalence rates of general obesity were 9.4% for males and 7.7% for females respectively. With aging, PBF and FMI showed a U-shape curvilinear trend and WPBW showed a parabolic trend for males. At same age group: 18-19 age groups, PBF and FMI declined to the valley and WPBW rose to the peak. For females, PBF, WPBW and FMI changed in a linear trend. The values of WPLBM and FFMI showed same curvilinear trend for two genders. WPLBM changed in a U-shape trend and touched the valley in twenties for males and in 18-19 age groups for females. The value of FFMI was larger for older age groups in the younger generation but smaller in the older generation. A parabolic trend peaking was seen in the thirties for males and in the forties for females. Regression models with age as independent variable showed that the larger rate of increase of PBF and smaller rates of increase for WPBM and WPLBM with aging for males. This study presents detailed data about sex-specific body composition conditions. Different change trend with aging was found about body composition conditions.

    Background: Folic acid supplementation is effective in reducing the risk of neural tube defects (NTDs). However, the use of folic acid is low among rural women in China. Nutrition education can provide information about folic acid and encourage its use. The primary objective of this study was to test the effectiveness of a village-based nutrition intervention on folic acid use among rural women. Methods: Sixty villages were randomly selected using multiple-stage sampling and were divided into control and intervention groups. The intervention included nutritional education at village clinics, written materials, and text messages (SMS). Folic acid use knowledge and behavior was assessed at baseline and after the intervention. Results: Self-reported compliance with folic acid supplement use increased from 17.0%–29.2% at baseline to 41.7%–59.2% one year post-intervention. During the same period, the folic acid knowledge score in the intervention group increased from 3.07 to 3.65, significantly higher than the control group (3.11 to 3.35). Multivariate binary logistic regression showed that the women who received folic acid education and SMS intervention were more likely to comply with folic acid supplement recommendations. Conclusions: The results indicated that an integrated village-based folic acid education intervention may be an effective way of promoting folic acid use for the prevention of NTDs in rural women.

    Three experiments investigated age of acquisition (AoA) effects on early orthographic processing during Chinese character recognition. In Experiment 1, we measured the accuracy of identification of brief masked characters, accuracy was higher for early compared to late acquired characters. In Experiment 2, the visual duration threshold (VDT) was measured for both early and late acquired Chinese characters. The results showed that early acquired characters were successfully identified at shorter display durations than late acquired characters. Significant AoA effects were also found in Experiment 3, using a lexical decision task requiring mainly orthographic processing (discriminating real Chinese characters from orthographically illegal and unpronounceable characters). In summary, three experiments provide converging empirical evidence, for AoA effects on the early orthographic processing stages of Chinese character recognition. These results suggest that AoA effects during word identification go beyond the phonological or semantic processing stages. These results aslo provide cross-linguistic evidence for an AoA effect on early perceptual processing during identification.

    PurposeTo report the age- and gender-adjusted prevalence rates of early and late age-related maculopathy (ARM) and associated risk factors in rural and urban Indian population.MethodsA population-based cross-sectional study was carried out in South India between 2009 and 2011. Of the 6617 subjects ≥60 years enumerated ones, 5495 (83.04%) participated in the eye examination. A detailed history including data on demographic, socioeconomic, and ocular history was obtained. Participants underwent detailed ophthalmic evaluation including 30° 3-field photograph as per Age-Related Eye Disease Study protocol. The ARM was graded according to the International ARM Epidemiological Study Group.ResultsAge- and gender-adjusted prevalence of early ARM was 20.91% (20.86-20.94) in the rural population and 16.37% (16.32-16.42) in the urban population. Similarly, the prevalence of late ARM was 2.26% (2.24-2.29) and 2.32% (2.29-2.34) in the rural and urban population, respectively. In both rural and urban populations, risk factors that were related to both early and late ARM were age, per year increase (OR, range 1.00-1.08); middle socioeconomic status (OR, range 1.05-1.83); and smokeless tobacco (OR, range 1.11-2.21). Protective factor in both was the presence of diabetes mellitus in all ARM (OR, range 0.34-0.83). Risk factors, only in the rural arm, were female gender (OR, range 1.06-1.64), past smoker (OR, 1.14), and serum low-density lipoprotein cholesterol level (OR, 1.03).ConclusionsThe study reports smokessless tobacco as a risk factor for both early and late ARM and identified a higher prevalence of early ARM in the rural population compared with urban population.

    Full Text Available Differences in the bacterial community structure associated with 7 skin sites in 71 healthy people over five days showed significant correlations with age, gender, physical skin parameters, and whether participants lived in urban or rural locations in the same city. While body site explained the majority of the variance in bacterial community structure, the composition of the skin-associated bacterial communities were predominantly influenced by whether the participants were living in an urban or rural environment, with a significantly greater relative abundance of Trabulsiella in urban populations. Adults maintained greater overall microbial diversity than adolescents or the elderly, while the intragroup variation among the elderly and rural populations was significantly greater. Skin-associated bacterial community structure and composition could predict whether a sample came from an urban or a rural resident ~5x greater than random.

    Several high pressure (HP) treatments (100–400 MPa 15 and 30 min) were applied to Chinese “Junchang” liquor, and aging characteristics of the liquor were evaluated. Results from the principal component analysis and the discriminant factor analysis of E-Nose demonstrated that HP treatment at 300 and 400 MPa resulted in significant (p natural aging process of Chinese liquor. However, HP treatment caused a slight increase in solid content, which might be somewhat undesirable. Sensory evaluation results confirmed that favorable changes in color and flavor of Chinese liquor were induced by HP treatment; however, overall gaps still existed between the quality of treated and six-year aged samples. HP treatment demonstrated a potential to accelerate the natural aging process for Chinese liquor, but long term studies may be needed further to realize the full potential.

    Full Text Available Background: Intellectual disability (ID is a global public health concern. Prevalence of ID and its association with age and other demographic factors is required for planning purposes in India. Objective: This study analyzed the age-adjusted prevalence of ID in rural and urban populations and its correlation with age in children and adults. Materials and Methods: Disability data published in the report (2002 of National Sample Survey Organization were analyzed, using Z-test to measure differences in age-adjusted prevalence. Spearman rho was calculated to determine strength and direction of the association, and regression analysis was used to predict prevalence rate, based on age in rural and urban population settings. Results: Overall, India has a prevalence of 10.5/1000 in ID. Urban population has slightly higher rate (11/1000 than rural (10.08/1000; P = 0.044. Age was found to be highly correlated with prevalence of ID in rural children (ϱ =0.981, P = 0.019 as well as in children (ϱ = −0.954, P = 0.000 and adults (ϱ = −0.957, P = 0.000 in urban population. The possibility of confounding or the existence of covariates for children in urban settings was noted. Conclusion: Results of this study match findings in other epidemiological studies. However, multistage, large-scale studies are recommended for investigating prevalence rates with different severity levels of ID.

    Full Text Available Background: It is predicted that cardiovascular diseases will be the most important cause of mortality in India by the year 2015. Since the key to combating the increased incidence of coronary artery disease (CAD is the control of known risk factors by a population based strategy aimed at comprehensive risk reduction, it is pertinent to study the magnitude of the risk. Aim: The present study was therefore conducted to assess the prevalence of certain coronary risk factors among rural population aged 35 years and above in Maharashtra. Methods: The present community based cross sectional survey was carried out in the rural area of Pune district on 272 subjects using a structured questionnaire, clinical examination followed by lab investigations. SPSS version 17.0 was used for analysis. Results: Tobacco consumption was found to be prevalent in 51.83% of the study subjects followed by physical inactivity which was prevalent among 31.61% whereas high diastolic blood pressure was found to be prevalent in 29.41% of the study subjects. Obesity and alcohol consumption were found to be prevalent among 13.97% of the study subjects. Among the biochemical parameters studied, hypertriglyceridemia was found to be prevalent in 22.05% followed by raised fasting blood sugar in 15.44% of the study subjects. Conclusion: Behaviour change communication strategies targeting these modifiable known high risk factors need to be emphasized to lower coronary heart disease (CHD related morbidity burden in the community.

    The aim of this study was to examine the pattern of femoral head epiphysis growth and development among Chinese children. Between January and December, 2007, we randomly sampled 1,450 healthy Chinese children (0-5 years old) from Hunan Provincial Children's Hospital in Changsha, Hunan, China. The diameter of femoral head epiphysis was measured by pelvic X-ray photography and processed by medical image processing software. The growth of femoral head epiphysis in girls was 2-3 months earlier than that in boys. The diameter of femoral head epiphysis increased with advancing age in both girls and boys, but the diameter of femoral head epiphysis in 2, 3, 4, 6, and 10-month-old girls was significantly larger than that in boys. Cubic regression equations between the diameter of femoral head epiphysis and age were created for boys and girls that could be used to predict the diameter of femoral head epiphysis. In conclusion, there was gender difference in femoral head epiphysis growth and development among Chinese children, and our prediction models will provide the guidance for early diagnosis of diseases related to the growth and development of the femoral head epiphysis.

    Full Text Available Abstract Background In 1997 Hong Kong reunified with China and the development of traditional Chinese medicine (TCM started with this change in national identity. However, the two latest discussion papers on Hong Kong's healthcare reform have failed to mention the role of TCM in primary healthcare, despite TCM's public popularity and its potential in tackling the chronic non-communicable disease (NCD challenge in the ageing population. This study aims to describe the interrelationship between age, non-communicable disease (NCD status, and the choice of TCM and western medicine (WM services in the Hong Kong population. Methods This study is a secondary analysis of the Thematic Household Survey (THS 2005 dataset. The THS is a Hong Kong population representative face to face survey was conducted by the Hong Kong Administrative Region Government of China. A random sample of respondents aged >15 years were invited to report their use of TCM and WM in the past year, together with other health and demographic information. A total of 33,263 persons were interviewed (response rate 79.2%. Results Amongst those who received outpatient services in the past year (n = 18,087, 80.23% only visited WM doctors, 3.17% consulted TCM practitioners solely, and 16.60% used both type of services (double consulters. Compared to those who only consulted WM doctor, multinomial logistic regression showed that double consulters were more likely to be older, female, NCD patients, and have higher socioeconomic backgrounds. Further analysis showed that the association between age and double consulting was curvilinear (inverted U shaped regardless of NCD status. Middle aged (45-60 years NCD patients, and the NCD free "young old" group (60-75 years were most likely to double consult. On the other hand, the relationship between age and use of TCM as an alternative to WM was linear regardless of NCD status. The NCD free segment of the population was more inclined to use TCM alone

    Online educational programs pose challenges to nonresidential graduate students for whom research is a key professional development experience. In this article, the authors share their pedagogical approach to engaging graduate-level online distance learners in research. Five students enrolled in an online master's degree program participated in a directed research course designed to facilitate a semester-long, collaborative, hands-on research experience in gerontology. As such, students recruited participants and conducted phone interviews for a multisite study examining aging in place in rural areas. Several strategies were used to facilitate student engagement and learning, including: regular meetings with faculty mentors, creation of a research team across institutions, interactive training, and technological tools to aid in communication. The authors discuss the process of implementing the project, challenges that arose, strategies for dealing with these issues, and a pedagogical framework that could be used to guide future endeavors of this type.

    Full Text Available Purpose: Rural health professionals in township health centers (THCs tend to have less advanced educational degrees. This study aimed to ascertain the perceived feasibility of a decentralized continuing medical education (CME program to upgrade their educational levels. Methods: A cross-sectional survey of THC health professionals was conducted using a self-administered, structured questionnaire in Guangxi Zhuang Autonomous Region, China. Results: The health professionals in the THCs were overwhelmingly young with low education levels. They had a strong desire to upgrade their educational degrees. The decentralized CME program was perceived as feasible by health workers with positive attitudes about the benefit for license examination, and by those who intended to improve their clinical diagnosis and treatment skills. The target groups of such a program were those who expected to undertake a bachelor’s degree and who rated themselves as “partially capable” in clinical competency. They reported that 160-400 USD annually would be an affordable fee for the program. Conclusion: A decentralized CME program was perceived feasible to upgrade rural health workers’ education level to a bachelor’s degree and improve their clinical competency.

    Background Suicide rates in China are among the highest in the world, although there has been a decreasing trend in the past few years. One practical approach to study the characteristics and risk factors of suicide is to interview the suicide attempters. Aims It was to compare completed suicides with serious attempters that may shed lights on suicide prevention strategies. Method This is a combination of two case control studies for suicide completers and suicide attempters respectively. After a sample of suicides (n=392) and community living controls (n=416) were obtained and studied in rural China, we collected in the same rural areas data of suicide attempt and studied 507 medically serious attempters and 503 community counterparts. Results Characteristics and previously observed risk factors were compared between the suicides and the attempters, and we found that the demographic characteristics and risk factors for the suicides were also for the medically serious attempters but at some lesser degrees for the attempters than for the suicides. It was especially true of suicide intent, deficient coping, negative life events, and impulsivity. While most of the demographic characteristics were not significantly different between the suicides and the attempters, most of the clinical variables could distinguish the two groups. Conclusions The suicide victims and the serious attempters could be of the same group of people who were at the edge of fatal self-injury, and the same clinical risk factors but of different degrees have divided them into the life and death groups.

    Full Text Available PURPOSE: The purpose of this hospital-based case-control study was to evaluate the patient-related risk factors for aseptic loosening after total hip arthroplasty (THA and total knee arthroplasty (TKA in Chinese patients. METHODS: From January 2000 to December 2012, 67 patients undergoing THA and TKA who developed aseptic loosening were detected as case subjects and 336 patients without aseptic loosening, matched by the year of index surgery and type of surgery, were selected as controls. Conditional logistic regression was used to compute odds ratios (ORs and 95% confidence intervals (CIs. RESULTS: The demographic factors and comorbid conditions associated with a risk-adjusted increase in aseptic loosening (in decreasing order of significance were a rural place of residence (OR = 2.28; 95% CI: 1.21-4.30; p = 0.011, body mass index (BMI ≥ 28 kg/m(2 (vs. 18.5-28 kg/m(2 (OR = 2.29; 95% CI: 1.19-4.41; p = 0.013, developmental dysplasia of the hip (DDH (OR = 2.91; 95% CI: 1.11-7.66; p = 0.030, tobacco abuse (OR = 2.88; 95% CI: 1.05-7.89; p = 0.039, and age <45 years (vs. 45-65 years (OR = 2.63; 95% CI: 1.01-6.80; p = 0.047. CONCLUSIONS: Patients aged <45 years and those with a BMI of ≥ 28 kg/m(2, a preoperative diagnosis of DDH, history of tobacco abuse, or living in rural areas are at increased risk for aseptic loosening after THA and TKA in Chinese population. Additional systematic large-scale studies are needed to verify these results.

    Full Text Available Background: Declining age at menarche has been observed in many countries. In China, a decrease of 4.5 months per decade in the average age at menarche among the majority Han girls has recently been reported. However, the trends in age at menarche among ethnic minority girls over the past 25 years remain unknown. Objectives: To compare the differences in median age at menarche among girls aged 9–18 years across 24 ethnic minorities in 2010 and to estimate the trends in age at menarche in different ethnic minorities from 1985 to 2010. Design: We used data from six cross-sectional Chinese National Surveys on Students’ Constitution and Health (1985, 1991, 1995, 2000, 2005, and 2010. The median age at menarche was estimated by using probit analysis. Results: In 2010, the ethnic minorities with the earliest age at menarche were the Koreans (11.79 years, Mongolians (12.44 years, and Zhuang (12.52 years. The three ethnic minorities with the latest age at menarche were the Sala (14.32 years, Yi (13.74 years, and Uighurs (13.67 years. From 1985 to 2010, the age at menarche declined in all 24 minority groups. The Lisu, Kazakh, and Korean minorities showed the largest reductions in age at menarche by 1.79 (p0.05, 0.15 (p>0.05, and 0.15 (p>0.05 years, respectively, in the same period. Conclusion: A large variation in age at menarche was observed among different ethnic minorities, with the earliest age at menarche found among Korean girls. A reduction in the average age at menarche appeared among most of the ethnic minorities over time, and the largest decrease was observed in Lisu, Kazakh, and Korean girls. Thus, health education should focus on targeting the specific needs of each ethnic minority group.

    Many kidney-tonifying Chinese herbal medicines exert effects on anti-aging by comprehensive interactions of multiple targets. However, the interactions of multi-targets targeted by effective ingredients of kidney-tonifying Chinese herbal medicines are unknown. In this study, to explore the systems pharmacology mechanisms of kidney-tonifying Chinese medicines on anti-aging, we establish the molecular networks with the interactions of multi-targets, analyze bio-functions and pathways with IPA, and calculated the mutual interaction pairs of targets (target pairs) with data mining, respectively. Kidney-tonifying Chinese medicines with anti-aging effects were screened from the Chinese Pharmacopoeia and the literatures. Target proteins of these herbal medicines were obtained from bioinformatics databases. Comparisons of molecular networks, bio-functions and pathways given by Ingenuity Pathway Analysis system showed the similarities and the differences between kidney Yin-tonifying herbal medicines and kidney Yang-tonifying herbal medicines. Target pairs with high correlation related to anti-aging were also discovered by data mining algorithm. And regulatory networks of targets were built based on the target pairs. Twenty-eight kidney-tonifying herbal medicines with anti-aging effects and 717 related target proteins were collected. The main bio-functions that all targets enriched in were "Cell Death and Survival", "Free Radical Scavenging" and "Cellular Movement", etc. The results of comparison analysis showed that kidney Yin-tonifying herbal medicines focused more on "Cancer related signaling", "Apoptosis related signaling" and "Cardiovascular related signaling". And kidney Yang-tonifying herbal medicines focused more on "Cellular stress and injury related signaling" and "Cellular growth, proliferation and development related signaling". Moreover, the results of regulatory network showed that the anti-aging related target pairs with high correlated degrees of Kidney Yin

    As one of the leading causes of death around the world, suicide is a global public health threat. In the Chinese population, suicides constitute one-fifth of all recorded suicides in the world. Despite the factual data on suicide rates, the understanding of various causal factors behind suicide, including risk and protective factors and adverse health care, remained incomplete among the global Chinese aging population. To fill in the knowledge void, this paper reviews the epidemiology of suicide among Chinese older adults globally as well as explores the existing intervention strategies. Using the PRISMA statement, we performed a systematic review of exiting research on the topic, including studies describing suicide among Chinese older adults in communities outside of Asia. A literature search was conducted online by using both medical and social science data-bases. Our findings highlighted that elderly suicide in Chinese populations is significantly affected by the social, cultural, and familial contexts within which the individual lived prior to committing suicide. Reviewing such research indicated that while reducing risk factors may contribute to lowering suicides amongst Chinese older adults, measures to improve protective factors are also critical. Support through ongoing family and community care relationships is necessary to improve resilience in older adults and positive aging. Future longitudinal studies on the risk factors and protective factors, and adverse health consequences are called for to devise culturally and linguistically appropriate prevention and intervention programs in global Chinese aging populations.

    Full Text Available Paired associates learning (PAL has been widely used in aging-related research, suggesting an age-related decline in associative learning. However, there are several cognitive processes (attention, spatial and recognition memory, strategy, and associative learning involved in PAL. It is unclear which component contributes to the decline in PAL performance associated with age effects. The present study determines whether age effects on associative learning are independent of other cognitive processes involved in PAL. Using a validated computerized cognitive program (CANTAB, we examined cognitive performance of associative learning, spatial and recognition memory, attention and strategy use in 184 Singaporean Chinese adults aged from 21 to 80 years old. Linear regression revealed significant age-related decline in associative learning, spatial and recognition memory, and the level of strategy use. This age-related decline in associative learning remains even after adjusting for attention, spatial and recognition memory, and strategy use. These results show that age effects on associative learning are independent of other cognitive processes involved in PAL.

    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.

    Full Text Available Rural Australians are less physically active than their metropolitan counterparts, and yet very little is known of the candidate intervention targets for promoting physical activity in rural populations. As rural regions are economically, socially and environmentally diverse, drivers of regular physical activity are likely to vary between regions. This study explored the region-specific correlates of daily walking among middle age and older adults in rural regions with contrasting dominant primary industries. Participants were recruited through print and electronic media, primary care settings and community organisations. Pedometers were worn by 153 adults for at least four days, including a weekend day. A questionnaire identified potential intra-personal, social and environmental correlates of physical activity, according to a social ecological framework. Regression modelling identified independent correlates of daily walking separately in the two study regions. In one region, there were independent correlates of walking from all levels of the social ecological framework. In the other region, significant correlates of daily walking were almost all demographic (age, education and marital status. Participants living alone were less likely to be physically active regardless of region. This study highlights the importance of considering region-specific factors when designing strategies for promoting regular walking among rural adults.

    Psychiatric disability is an important public health problem in China, and poverty may be positively correlated with disability. Little study in the existing literatures has explored the contribution of poverty to the psychiatric disability among Chinese population. Using a nationally representative data, this paper aims to investigate the association between poverty and psychiatric disability in Chinese population aged 15-64 years. We used the second China National Sample Survey on Disability, comprising 1.8 million people aged 15-64 years. Identification and classification for psychiatric disability was based on consensus manuals. We used standard weighting procedures to construct sample weights considering the multistage stratified cluster sampling survey scheme. Population weighted numbers, weighted proportions, and the adjusted Odd Ratios (OR) were calculated. For people with psychiatric disability aged 15-64 years, more than 4 million were below the poverty level in China. After controlling for other demographic variables, poverty was found to be significantly associated with psychiatric disability (OR=2.25, 95% Confidence Interval (CI) 2.15-2.35). Given China is undergoing rapid social-economic transition and psychiatric diseases become a leading burden to the individuals, community, and health care systems, poverty reduction programs are warranted to prevent psychiatric disability and/or improve the lives for persons with psychiatric disability.

    Genetic factors play an important role in the Alzheimer's disease (AD) development and memory impairment is a cardinal clinical feature of AD. Kidney and brain expressed protein (KIBRA), owing to its connection with human episodic memory, became an interesting candidate gene for AD. Recently, KIBRA (rs17070145) was reported to be associated with AD in the genetic and functional levels in Caucasian and African-American, and the association might be different across age groups. To investigate the possibility of age-dependent association of KIBRA with AD in Asian, we conducted an independent replication study in a cohort of 1,586 subjects from Han Chinese (including 790 LOAD patients and 796 healthy controls). The results revealed no significant differences in the distributions of genotype or allele between LOAD and control groups in the total sample. However, when these data were stratified by their age, we observed a significant difference in the genotypes and alleles frequencies (genotype: p = 0.004, allele: p = 0.035) in the young subgroup. Moreover, the association was further demonstrated in logistic regression analysis (rs17070145: p = 0.045, OR = 0.428). Our data suggested that KIBRA might associate with younger AD patients (≤74 years) in a Northern Han Chinese population.

    The Chinese Loess Plateau contains red clay sequence which has continuous alternation of sedimentary cycles with recurrent paleoclimatic fluctuations. Absence of abundant fossils and inability of radiometric dating method made magnetostratigraphy a leading method to build age model for the red clay. Here magnetostratigraphic age model in red clay sequence is tested using cyclostratigraphy as orbital parameters of Earth are known. Milankovitch periodicities recorded in magnetic susceptibility and grain size in the Shilou red clay section are investigated and previously found age of 11 Ma for this section is re-evaluated. Magnetostratigraphy dating based on only visual correlation could potentially lead to erroneous age model. In this study the correlation is executed through the iteration procedure until it is supported by cyclostratigraphy; i.e. Milankovitch cycles are resolved in the best possible manner. Our new approach provides an age of 5.2 Ma for the Shilou profile. Wavelet analysis reveals that a 400 kyr eccentricity cycle is well preserved and the existence of a 100 kyr eccentricity in the red clay sequence on the eastern Chinese Loess Plateau suggests that eccentricity plays a vital role in Pliocene climate evolution. Paleomonsoon evolution is reconstructed and divided into three intervals (5.2-4.5 Ma, 4.5-3.6 Ma and 3.6-2.58 Ma). The earliest stage indicates that summer and winter monsoon cycles may rapidly alter, whereas the middle stage reflects an intensification of winter monsoon and aridification in Asia, and the youngest stage is characterized by relatively intensified summer monsoon. This study demonstrates that cyclostratigraphy can greatly assist magnetostratigraphy in dating the red clay sequences, and implies that many published age models for the red clay sequences should likely be re-assessed where possible. An evaluation of the monsoon system and climate change in eastern Asia might prominently benefit from this approach.

However, sex differences in cognitive function and obesity in cognitively normal aging Chinese Han population have not attracted much attention. Objective: The aim of this study was to investigate the relationship between sex, obesity, and cognitive function in an elderly Chinese population with normal cognitive function. Subjects and methods: A total of 228 cognitively normal aging participants (males/females =93/135 entered this study. Their general demographic information (sex, age, and education was collected by standardized questionnaire. Apolipoprotein E (APOE genotype and serum lipid levels were measured. The Montreal Cognitive Assessment (MoCA was used to assess participants’ cognitive function. Results: The prevalence of obesity in elderly women (18/133, 13.5% was significantly higher than that in men (5/92, 5.4%, P=0.009. Regression analyses showed that obesity was associated with drinking alcohol (OR =13.695, P=0.045 and triglyceride (OR =1.436, P=0.048 in women and limited to low-density lipoprotein (OR =11.829, P=0.023 in men. Women performed worse on the naming score for MoCA than men (P<0.01. Stepwise linear regression analysis showed that education (t=3.689, P<0.001 and smoking (t=2.031, P=0.045 were related to the score of naming in female, while high-density lipoprotein (t=–2.077, P=0.041 was related to the score of naming in male; however, no correlation was found between body mass index and cognitive function in both male and female (P>0.05. Conclusion: Our finding suggests that there are significant sex differences in obesity and

    Full Text Available Abstract Background There has been very little research on wellbeing, physical impairments and disability in older people in developing countries. Methods A community survey of 1147 older parents, one per household, aged sixty and over in rural Thailand. We used the Burvill scale of physical impairment, the Thai Psychological Wellbeing Scale and the brief WHO Disability Assessment Schedule. We rated received and perceived social support separately from children and from others and rated support to children. We used weighted analyses to take account of the sampling design. Results Impairments due to arthritis, pain, paralysis, vision, stomach problems or breathing were all associated with lower wellbeing. After adjusting for disability, only impairment due to paralysis was independently associated with lowered wellbeing. The effect of having two or more impairments compared to none was associated with lowered wellbeing after adjusting for demographic factors and social support (adjusted difference -2.37 on the well-being scale with SD = 7.9, p Conclusion In this Thai setting, as found in western settings, most of the association between physical impairments and lower wellbeing is explained by disability. Disability is potentially mediating the association between impairment and low wellbeing. Received support may buffer the impact of some impairments on wellbeing in this setting. Giving actual support to children is associated with less wellbeing unless the support being given to children is perceived as good, perhaps reflecting parental obligation to support adult children in need. Improving community disability services for older people and optimizing received social support will be vital in rural areas in developing countries.

    Full Text Available This paper evaluated the effect of capitation payment reform in New Rural Cooperative Medical Scheme designating primary facilities in Qianjiang 2007-2009. Retrospective administrative claims were analyzed. Intercepts changes of cost per visit in facilities started the reform in different stages and of overall Qianjiang were compared. Referral rate, prescribing indicators, hospitalization rate, income of facility and individuals were compared pre- and post- the reform. Growth rate of cost per visit in health centers was contained in 2008, kept unchanged in 2009. Cost containment effect on village clinics was observed in each starting stage of reforms, but vanished later on. Except for the fact the proportion of essential medicines used in health centers significantly increased (X2 test, P<0.05, prescription indicators were not improved significantly in all facilities. After a slight increase in 2007, the hospitalization rate continuously dropped. The monthly income and outpatient revenue continuously increased in 2006-2009. Cost containment objective of the capitation reform was achieved immediately following the reform, but was not sustainable. Provider behaviors were partially improved with limited effects on prescriptions behaviors. The reform brought no financial loss to both the facilities and individuals.

    Full Text Available Background: The identification of major dietary patterns using factor analysis can provide information about health status of children by obtaining an overall picture of the person's diet. The aim of this study was to determine major dietary patterns and to identify socioeconomic factors affecting them in school age children in rural areas of Bijar, Iran. Materials and Methods: In this cross sectional study, 255 rural school age children living rural areas of Bijar were selected by simple random sampling. Dietary intakes during the past year and assessment of socioeconomic information were examined. Dietary patterns were determined using factor analysis and their relation to socioeconomic factors was investigated. Results: Three major dietary patterns," traditional", "modern" and "mixed", were identified. After adjusting for age, sex, ethnic and energy intake, Age of mother (b= 0.03, CI=0.00_0.05 was positively associated and age of father (b= -0.03, CI=-0.05_-0.01, laboring Job for father (b= -0.24, CI=-0.44_-0.03 and higher education of parents (b= -0.20, CI=-0.35_-0.05 were negatively associated with traditional dietary pattern. In addition, higher education of parents (b= 0.27, CI=0.11_0.44 was positively associated and age of mother (b= -0.03, CI=-0.06_0.00 was negatively associated with mixed dietary pattern. Conclusion: Some socio-economic variables such as maternal age, parental education, parental occupation and economic conditions can have effect on major dietary patterns among rural children.

    Central obesity is considered to be a central component of metabolic syndrome. Waist circumference (WC) has been widely used as a simple indicator of central obesity. This study is aimed to evaluate the sensitivity of WC cut-off values for predicting metabolic risk factors in middle-aged Chinese. The study involved 923 subjects aged 40-65 years. The metabolic risk factors were defined according to the Chinese Joint Committee for Developing Chinese Guidelines on Prevention and Treatment of Dyslipidemia in Adults. WC cut-off 85-90 cm and ⋝90 cm were used as cut-off values of central pre-obesity and central obesity in males, respectively, while WC 80-85 cm and ⋝85 cm were used as cut-off values of central pre-obesity and central obesity in females. First, WC values corresponding to body mass index (BMI) 24 kg/m2 and visceral fat area (VFA) 80 cm2 were 88.55 cm and 88.51 cm in males, and 81.46 cm and 82.51 cm in females respectively. Second, receiver operating characteristic curves showed that the optimal WC cut-off of value was 88.75 cm in males, higher than that in females (81.75 cm). Third, the subjects with higher WC values were more likely to have accumulating metabolic risk factors. The prevalence of metabolic risk factors increased linearly and significantly in relation to WC levels. WC cut-off values of central pre-/central obesity are optimal to predict multiple metabolic risk factors. Copyright © 2014 The Editorial Board of Biomedical and Environmental Sciences.

The sexual desire plays an important role in mental health and improving the quality of life. Objectives The current study aimed to compare sexual function of females in urban and rural areas. Methods The current descriptive study adopted 800 females of reproductive age (range 15 - 45 years referred to rural and urban healthcare centers in Ahvaz, Iran, in 2015. Samples were randomly selected. Applied instruments in the study were demographic information and female sexual dysfunction questionnaires (FSFI. Independent T-test, Chi-square and logistic regression were employed to analyze data by SPSS ver. 22. Results The result showed a significant statistical difference between females in urban and rural areas in terms of sexual desire, vaginal lubrication, intercourse pain and sexual function (P 0.05. Frequency of sexual dysfunction was 59.9% in females in rural and36.5% in urban areas and the difference between the groups was statistically significant (0.000. In both groups, the highest sexual disorder frequency was related to intercourse pain. Conclusions According to the obtained results, females in the rural areas had lower sexual function than the ones in the urban areas. It is suggested to establish female sexual health units in healthcare centers to give female sexual function consultation adjusted with awareness and culture of females and consider the existing problems.

    Understanding the age effect on soil carbon balance in forest ecosystems is important for other material cycles and forest man-agement. In this research we investigated soil organic carbon density, litter production, litter decomposition rate, soil respiration, and soil mi-crobial properties in a chronosequence of four Chinese fir plantations of 7, 16, 23 and 29 years at Dagangshan mountain range, Jiangxi Province, south China. There was a significant increasing trend in litter production with increasing plantation age. Litter decomposition rate and soil respira-tion, however, declined from the 7-year to the 16-year plantation, and then increased after 16 years. This was largely dependent on soil micro-organisms. Soil carbon output was higher than carbon input before 16 years, and total soil carbon stock declined from 35.98 t·ha-1 in the 7-year plantation to 30.12 t·ha-1 in the 16-year plantation. Greater litter produc-tion could not explain the greater soil carbon stock, suggesting that forest growth impacted this microbial process that controlled rates of soil car-bon balance together with litter and soil respiration. The results highlight the importance of the development stage in assessing soil carbon budget and its significance to future management of Chinese fir plantations.

    Insufficient sleep in school-aged children is common in modern society, with homework burden being a potential risk factor. The aim of this article is to explore the effect of sleep hygiene on the association between homework and sleep duration. Children filled out the Chinese version of the Adolescent Sleep Hygiene Scale, and parents filled out a sociodemographic questionnaire. The final sample included 363 boys and 371 girls with a mean age of 10.82 ± 0.38 years. Children with more homework went to bed later and slept less. Better sleep hygiene was associated with earlier bedtimes and longer sleep duration. Findings suggest that homework burden had a larger effect on sleep duration than sleep hygiene. Fifth-grade children in Shanghai have an excessive homework burden, which overwrites the benefit of sleep hygiene on sleep duration.

    This study aimed to determine whether associations between the perceived environment and physical activity are moderated by urban-rural status among midolder aged adults. Environmental (safety, aesthetics, physical activity environment) and physical activity (total, leisure, transport) data from 3,888 adults (55 to 65 years) from urban and rural areas of Victoria, Australia, were analyzed. Multinomial logistic regression examined interactions between urban-rural status and environments in associations with physical activity. Significant (P physical activity (e.g., rural adults reporting higher safety were 91% to 118% more likely to have higher activity than rural adults reporting low safety). In contrast, the physical activity environment was positively associated with leisure activity among only urban adults. Findings suggest that some tailoring of physical activity promotion strategies targeting the environment may be required for urban and rural midolder aged adults.

    The association between dental caries and metabolic syndrome (MetS) is inconsistent. The aim of the present study was to assess the relationship between dental caries and MetS and its components in a middle-aged Chinese population. A cross-sectional analysis was performed of 13 998 participants aged 45-65 years undergoing a health check during 2013-14. An index variable of decayed, missing, and filled teeth (DMFT) was calculated. Logistic regression was used to estimate odds ratios (ORs) and 95 % confidence intervals (CIs) after adjustment for sex, age, education level, dietary habits, alcohol use, smoking, physical activity, and periodontitis. Of the 13 998 participants, 6164 had dental caries and 7834 did not; 3571 had MetS, whereas 10 427 did not.

    China's rapid urbanization over the past decades has exacerbated the problems of environmental degradation and health disparities. However, few studies have analysed the differences between urban and rural residents in relation to how environmental quality impacts health outcomes. This study examines the associations between Chinese people's perceptions of environmental quality and their self-rated health, particularly focusing on differences between rural and urban residents in environment-health relationships. Using a logistic regression model and data from the 2013 Chinese General Social Survey (CGSS), a representative sample of data for 3,402 urban residents (46 ± 16 years) and 2,439 rural residents (48 ± 15 years) was analysed. The dependent variable used for the logistic regressions was whether or not respondents reported being healthy. Independent variables included respondents' evaluations of the living environment, and how frequently they participated in physical activities. Interaction terms were employed to measure the moderating effects of physical exercise on the relationship between perceived environmental quality and health. The percentage of healthy urban residents was significantly larger than that of healthy rural respondents (70.87% versus 62.87%). Urban respondents living in areas with sufficient green space were more likely to report good health (OR = 0.749, CI = [0.628, 0.895]), while rural respondents without reliable access to fresh water were more likely to report poor health (OR = 0.762, CI = [0.612, 0.949]). Urban respondents who were exposed to green spaces and exercised frequently were 21.6 per cent more likely to report good health than those who exercised infrequently (OR = 1.216, CI = [1.047, 1.413]). Those who lived in areas with insufficient green space and exercised frequently were 19.1 per cent less likely to report good health than those who exercised infrequently (OR = 0.805, CI = [0

    Background: Older adults in rural areas have unique transportation barriers to accessing medical care, which include a lack of mass transit options and considerable distances to health-related services. This study contrasts non-emergency medical transportation (NEMT) service utilization patterns and associated costs for Medicaid middle-aged and older adults in rural versus urban areas. Methods: Data were analyzed from 39,194 NEMT users of LogistiCare-brokered services in Delaware residing in rural (68.3%) and urban (30.9%) areas. Multivariable logistic analyses compared trip characteristics by rurality designation. Results: Rural (37.2%) and urban (41.2%) participants used services more frequently for dialysis than for any other medical concern. Older age and personal accompaniment were more common and wheel chair use was less common for rural trips. The mean cost per trip was greater for rural users (difference of $2910 per trip), which was attributed to the greater distance per trip in rural areas. Conclusions: Among a sample who were eligible for subsidized NEMT and who utilized this service, rural trips tended to be longer and, therefore, higher in cost. Over 50% of trips were made for dialysis highlighting the need to address prevention and, potentially, health service improvements for rural dialysis patients. PMID:28208610

    South Africa has the highest number of people living with HIV in the world (over 6 million) as well as a rapidly aging population, with 15% of the population aged 50 and over. High HIV prevalence in rural former apartheid homeland areas suggests substantial aging with HIV and acquisition of HIV at older ages. We develop a life course approach to HIV vulnerability, highlighting the rise and fall of risk and protection as people age, as well as the role of contextual density in shaping HIV vulnerability. Using this approach, we draw on an innovative multi-method data set collected within the Agincourt Health and Demographic Surveillance System in South Africa, combining survey data with 60 nested life history interviews and 9 community focus group interviews. We examine HIV risk and protective factors among adults aged 40-80, as well as how and why these factors vary among people at older ages.

    Many rural communities are experiencing an increase in their older adult population. Older adults who live in rural areas typically have fewer resources and poorer mental and physical health status than do their urban counterparts. Depression is the most prevalent mental health problem among older adults, and 80% of the cases are treatable. Unfortunately, for many rural elders, depressive disorders are widely under-recognized and often untreated or undertreated. Psychotherapy is illustrated with the case of a 65-year-old rural married man whose presenting complaint was depressive symptoms after a myocardial infarction and loss of ability to work. The case illustrates that respect for rural elderly clients' deeply held beliefs about gender and therapy, coupled with an understanding of their limited resources, can be combined with psychoeducational and therapeutic interventions to offer new options.

    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.

    Full Text Available To examine the age and sex-specific associations of urine levels of six mono-phthalates with body size and fat distribution in Chinese children at puberty.Four hundred and ninety-three school-aged children (247 boys, 246 girls were recruited. Obesity related anthropometric indices were measured and body fat proportion (BF% was calculated. Spot urine samples were collected and phthalate monoesters were detected by an API 2000 electrospray triple quadrupole mass spectrometer (ESI-MS/MS. Associations between phthalate exposure and overweight/obesity measures and their trends were examined by multiple linear regression and Logistic regression analyses, respectively.Di-2-ethylhexyl phthalate (DEHP metabolites and monobutyl phthalate (MBP were found to be the most detectable chemicals. In 8-10 years (yrs group, concentrations of MEHP and MBP were significantly higher in girls than those in boys. However, concentrations of all phthalate monoesters, except for MEP and MEHP, in 11-13 yrs boys were significantly higher than those in girls. After adjusting for confounders including puberty onset, urinary concentrations of MBP and sum of low molecular-weight phthalate metabolites (∑LMP were positively associated with boys' obesity in a concentration-effect manner, while concentrations of MEHP, MEHHP and sum of DEHP metabolites (∑MEHP were negatively associated with girls' obesity. Associations between phthalate exposure levels and BMI z-score changes were age- and sex-specific in school-age children.There are age and sex-specific concentration-effect associations between phthalate exposure and fat distribution in Chinese children. Urinary phthalate levels in 11-13 yrs boys were about 30 percent higher than those in girls, and ∑MEHP levels in younger boys (10 yrs. Associations were positive for MBP and ∑LMP with both BMI z-score and fat distribution in boys >10 years of age, and negative for ∑MEHP with fat distribution in girls <10 years of age.

    Full Text Available BACKGROUND: Age at natural menopause (ANM is a complex trait with high heritability and is associated with several major hormonal-related diseases. Recently, several genome-wide association studies (GWAS, conducted exclusively among women of European ancestry, have discovered dozens of genetic loci influencing ANM. No study has been conducted to evaluate whether these findings can be generalized to Chinese women. METHODOLOGY/PRINCIPAL FINDINGS: We evaluated the index single nucleotide polymorphisms (SNPs in 19 GWAS-identified genetic susceptibility loci for ANM among 3,533 Chinese women who had natural menopause. We also investigated 3 additional SNPs which were in LD with the index SNP in European-ancestry but not in Asian-ancestry populations. Two genetic risk scores (GRS were calculated to summarize SNPs across multiple loci one for all SNPs tested (GRSall, and one for SNPs which showed association in our study (GRSsel. All 22 SNPs showed the same association direction as previously reported. Eight SNPs were nominally statistically significant with P≤0.05: rs4246511 (RHBDL2, rs12461110 (NLRP11, rs2307449 (POLG, rs12611091 (BRSK1, rs1172822 (BRSK1, rs365132 (UIMC1, rs2720044 (ASH2L, and rs7246479 (TMEM150B. Especially, SNPs rs4246511, rs365132, rs1172822, and rs7246479 remained significant even after Bonferroni correction. Significant associations were observed for GRS. Women in the highest quartile began menopause 0.7 years (P = 3.24×10(-9 and 0.9 years (P = 4.61×10(-11 later than those in the lowest quartile for GRSsel and GRSall, respectively. CONCLUSIONS: Among the 22 investigated SNPs, eight showed associations with ANM (P<0.05 in our Chinese population. Results from this study extend some recent GWAS findings to the Asian-ancestry population and may guide future efforts to identify genetic determination of menopause.

    To investigate alcohol drinking status and the association between drinking patterns and visual impairment in an adult population in northern China. Cluster sampling was used to select samples. The protocol consisted of an interview, pilot study, visual acuity (VA) testing and a clinical examination. Visual impairment was defined as presenting VA worse than 20/60 in any eye. Drinking patterns included drinking quantity (standard drinks per week) and frequency (drinking days in the past week). Information on alcohol consumption was obtained from 8445 subjects, 963 (11.4%) of whom reported consuming alcohol. In multivariate analysis, alcohol consumption was significantly associated with older age (p 14 drinks/week) was associated with higher odds of visual impairment. However, moderate intake (>1-14 drinks/week) was significantly associated with lower odds (adjusted odds ratio, OR, 0.7, 95% confidence interval, CI, 0.5-1.0) of visual impairment (p = 0.03). Higher drinking frequency was significantly associated with higher odds of visual impairment. Multivariate analysis showed that older age, male sex, and higher education level were associated with visual impairment among current drinkers. Age- and sex-adjusted ORs for the association of cataract and alcohol intake showed that higher alcohol consumption was not significantly associated with an increased prevalence of cataract (OR 1.2, 95% CI 0.4-3.6), whereas light and moderate alcohol consumption appeared to reduce incidence of cataract. Drinking patterns were associated with visual impairment. Heavy intake had negative effects on distance vision; meanwhile, moderate intake had a positive effect on distance vision.

    The purpose of this study was to develop a protein chip technique based on receptor binding assays to measure bioavailable serum sex hormone levels (BSSHL). 224 aging healthy Chinese were investigated to get the referenced values of BSSHL for the first time. In the assays recombined sex hormone receptor proteins were jointed to polysaccharide coated slides to make protein chip, and the dose-dependence curves of sex hormone on chip were prepared. The data showed that this method had good precision (CV<16%) and accuracy (Bias<10%), and the sensitivity could reach 1 pmol/L. From the results, BSSHL of men and women declined with aging, but no significant differences were observed. The BSSHL of aging men were higher than those of women. The bioavailable serum androgen level of men was 52―112 pmol/L, women's was 3―70 pmol/L and the whole group was 41.9―81.4 pmol/L. The bioavailable serum estrogen level of men was 0.8―3.0 pmol/L, women's was 1.2―2.5 pmol/L and the whole group was 0.6―2.64 pmol/L. Based on the assays, BSSHL measurement by protein chip can meet the needs of epidemiological studies in terms of speed, accuracy and sample volume required, and was helpful in quantitative assessment of aging people's health.

    To evaluate the effectiveness of a self-directed learning package in increasing palliative care knowledge and confidence for aged care workers in Rural New South Wales, Australia. Participants piloted a palliative care self-directed learning package and completed pre- and post-package knowledge and confidence questionnaires with a 6-month follow-up. The data was then analysed via paired two-tailed T-tests. There was a statistically significant mean increase in knowledge and confidence after completion of the self-directed learning package. Knowledge but not confidence increases were retained after 6 months. Self-directed learning packages can play a part in increasing knowledge and confidence in palliative care for rural aged care workers. Questions remain regarding the role of ongoing support, education, and mentoring.

    The age of acquisition of a word (AoA) has a specific effect on brain activation during word identification in English and German. However, the neural locus of AoA effects differs across studies. According to Hernandez and Fiebach [Hernandez, A., & Fiebach, C. (2006). The brain bases of reading late-learned words: Evidence from functional MRI. Visual Cognition, 13(8), 1027-1043], the effects of AoA on brain activation depend on the predictability of the connections between input (orthography) and output (phonology) in a lexical network. We tested this hypothesis by examining AoA effects in a non-alphabetic script with relatively arbitrary mappings between orthography and phonology--Chinese. Our results showed that the effects of AoA in Chinese speakers are located in brain regions that are spatially distinctive including the bilateral middle temporal gyrus and the left inferior parietal cortex. An additional finding was that word frequency had an independent effect on brain activation in the right middle occipital gyrus only. We conclude that spatially distinctive effects of AoA on neural activity depend on the predictability of the mappings between orthography and phonology and reflect a division of labour towards greater lexical-semantic retrieval in non-alphabetic scripts.

    Full Text Available Introduction: Teeth and dental restorations are resistant to destruction by fire and the elements are therefore useful in identification. This permits accurate identification of a missing child or remains. The Rural Residential free school at Suttur houses a large number of inmates and hence dental records are kept for their identification. Objective: Estimation of Age of children. Methods: Orthopantomographs were used to study for estimation of age of children, using a Nolla’s method of dental age estimation. Results: In this study Nolla’s method underestimated the chronological age of the individuals and underestimation of age increased as the chronological age of the individuals increased. Conclusion: Studies involving larger sample size and population specific data needs to be developed.

    Full Text Available PURPOSE: To investigate the prevalence and visual acuity (VA outcomes of cataract surgery in adults of the Bai Nationality populations in rural China. METHODS: We conducted a population-based cross-sectional survey (from randomly selected block groups of Chinese Bai Nationality aged ≥50 years in southwestern China. Presenting visual acuity (PVA, best corrected visual acuity (BCVA were recorded and a detailed eye examination was carried out. For all aphakic and pseudophakic subjects identified, information on the date, setting, type, and complications of cataract surgery were recorded. In eyes with VA <20/63, the principal cause of visual impairment was identified. RESULTS: Of 2133 (77.8% of 2742 subjects, 99 people (129 eyes had undergone cataract surgery. The prevalence of cataract surgery was 4.6%. Surgical coverage among those with PVA <20/200 in both eyes because of cataract was 52.8%. Unoperated cataract was associated with older age. The main barrier to cataract surgery was lack of awareness and knowledge, cost, and fear. Among the 129 cataract-operated eyes, 22.5% had PVA of ≥20/32, 25.6% had PVA of 20/40 to 20/63, 23.3% had PVA <20/63 to 20/200, and 28.7% had PVA<20/200. With BCVA, the percentages were 42.6%, 23.3%, 10.9%, and 23.3%, respectively. Aphakia (odds ratio [OR], 8.49; P<0.001 and no education (OR, 10.18; P = 0.001 or less education (OR, 6.49; P = 0.014 were significantly associated with postoperative visual impairment defined by PVA, while aphakia (OR, 8.49; P<0.001 and female gender (OR, 4.19; P = 0.004 were significantly associated with postoperative visual impairment by BCVA. The main causes of postoperative visual impairment were refractive error, retinal disorders and glaucoma. CONCLUSIONS: Half of those with bilateral visual impairment or blindness because of cataract remain in need of cataract surgery in Bai population. Surgical uptake and visual outcomes should be further improved in the future.

    Full Text Available We examined age differences in self-perceptions of five dimensions of mastery motivation and also of competence in American, Chinese, and Hungarian children and teens. Participants included 200 Americans, 1,465 Chinese, and 8,175 Hungarians from 7 to 19 years of age. The Dimensions of Mastery Questionnaire provides comparable data across these different cultures as indicated by very similar factor structures and reasonably good internal consistency reliabilities for the scales. Across all three cultures, there was the expected decline from primary to secondary school in total persistence and the four instrumental mastery motivation scales, except for social persistence with adults in the American sample. Mastery pleasure did not decline in the American and Chinese samples but declined in the Hungarian sample. Self-perceived competence did not decline significantly in the American sample or in the Hungarian sample from age 11 to 17; however, competence self-ratings declined in the Chinese sample. The three cultures were compared at 11 and 16. Although there were some significant differences, small effect sizes indicated that the level of motivation was similar for each culture at each age. The other literature provides clues about why the declines occur in all three cultures and why there are some differences among cultures.

    Genetic and environmental influences on predictors of decline in daily functioning, including forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), handgrip, and five-times-sit-to-stand test (FTSST), have not been addressed in the aging Chinese population. We performed classical twin...... was moderate for FEV1, handgrip, and FTSST (55-60%) but insignificant for FVC. Only FVC showed moderate control, with shared environmental factors accounting for about 50% of the total variance. In contrast, all measures of pulmonary function and muscle strength showed modest influences from the unique...... direction. We conclude that genetic factors contribute significantly to the individual differences in common indicators of daily functioning (FEV1, handgrip, and FTSST). FEV1 and FVC were genetically and environmentally correlated. Pulmonary function and FTSST may share similar sets of genes...

    Full Text Available Background. Ear infections in children are a major health problem and may be associated with hearing impairment and delayed language development. Objective. To determine the prevalence and the associated risk factors of ear infections in children 6–17 years old residing on two reserves and rural areas in the province of Saskatchewan. Methodology. Data were provided from two rural cross-sectional children studies. Outcome variable of interest was presence/absence of an ear infection. Logistic regression analysis was conducted to examine the relationship between ear infection and the other covariates. Results. The prevalence of ear infection was 57.8% for rural Caucasian children and 43.6% for First Nations children living on-reserve. First Nations children had a lower risk of ear infection. Ear infection prevalence was positively associated with younger age; first born in the family; self-reported physician-diagnosed tonsillitis; self-reported physician-diagnosed asthma; and any respiratory related allergy. Protective effect of breastfeeding longer than three months was observed on the prevalence of ear infection. Conclusions. While ear infection is a prevalent condition of childhood, First Nations children were less likely to have a history of ear infections when compared to their rural Caucasian counterparts.

    Full Text Available Background. Over the last decade, Thailand has experienced an aging population, especially in rural areas. Research finds a strong, positive relationship between good quality housing and health, and this paper assesses the impact and living experience of housing of older people in rural Thailand. Methods. This was a mixed-method study, using data from observations of the physical adequacy of housing, semistructured interviews with key informants, and archival information from health records for 13 households in rural Thailand. Results. There were four main themes, each of which led to health risks for the older people: “lighting and unsafe wires,” “house design and composition,” “maintenance of the house,” and “health care equipment.” The housing was not appropriately designed to accommodate health care equipment or to fully support individual daily activities of older people. Numerous accidents occurred as a direct result of inadequate housing and the majority of houses had insufficient and unsafe lighting, floor surfaces and furniture that created health risks, and toilets or beds that were at an unsuitable height for older people. Conclusion. This paper provides an improved and an important understanding of the housing situation among older people living in rural areas in Thailand.

The ADHD group was divided into subgroups: ADHD-I (predominantly inattentive and ADHD-C (combined type. (The ADHD-H [hyperactive] group was excluded because of small sample size. The Wechsler Intelligence Scale for Children-IV Chinese version was administered to every participant, and the FSIQ (Full-Scale IQ score was used as the measure of IQ.Results: Both boys with HFASD and ADHD (ADHD-I and ADHD-C showed impairments in Processing Speed Index and FSIQ, as compared to the TD group. Lower Verbal Comprehension Index scores were found in the ASD and ADHD-I groups. Interestingly, Working Memory Index was only impaired in children with ADHD. Additionally, equivalent Perceptual Reasoning Index (PRI scores were found among the HFASD, ADHD, and TD groups.Conclusion: Results indicated that both children with ADHD and HFASD have difficulty in processing speed, which may be explained by these children having neurodevelopmental disorders. These results also indicated that working memory appears to only be impacted by having ADHD. Children

    This study aimed to examine the socio-demographic and socioeconomic characteristics associated with prevalence and severity of elder self-neglect in an U.S. Chinese older population. The PINE study is a population-based epidemiological study in the greater Chicago area. In total, 3159 Chinese older adults were interviewed from 2011 to 2013. Elder self-neglect was assessed with systematic observations of a participant's personal and home environment across five domains: hoarding, personal hygiene, house in need of repair, unsanitary conditions, and inadequate utility. Elder self-neglect was prevalent among older adults aged 80 years or over (mild self-neglect: 34.6% 95% CI 30.9-38.4; moderate/severe: 15.6% 95% CI 12.8-18.6), men (mild: 28.6% 95% CI 26.1-31.3; moderate/severe: 13.1% 95% CI 11.2-15.1), those with 0-6 years of education (mild: 32.2% 95% CI 29.7-34.9; moderate/severe: 12.6% 95% CI 10.8-14.5), and those with an annual personal income between $5000 and $10,000 (mild: 30.8% 95% CI 28.4-33.2; moderate/severe: 11.8% 95% CI 10.2-13.5). Older age (mild self-neglect: OR 1.02, 95% CI 1.01-1.03; moderate/severe self-neglect: OR 1.02, 95% CI 1.00-1.03) and lower education levels (mild self-neglect: OR 1.06, 95% CI 1.03-1.08; moderate/severe self-neglect: OR 1.07, 95% CI 1.04-1.09) were associated with significantly increased odds of elder self-neglect. Women (moderate/severe self-neglect: OR 0.73, 95% CI 0.58-0.93) had significantly decreased odds of moderate/severe elder self-neglect. No significant association was found between levels of income and overall elder-self-neglect of all severities. Future research is needed to examine risk/protective factors associated with elder self-neglect in U.S. Chinese older populations.

    Full Text Available Abstract Background The first 18 months of life are the most important for long-term childhood well-being. Anemia and malnutrition occurring in this key period have serious implications for individuals and societies, especially in rural areas in developing country. We conducted a cross-sectional study as the baseline survey to provide data for developing a policy-based approach to controlling infant anemia and malnutrition in rural areas of Shaanxi province in northwestern China. Methods We randomly sampled 336 infants aged 0–18 months in 28 rural villages from 2 counties of Shaanxi province. Anthropometric measurements and household interviews were carried out by well-trained researchers. The hemoglobin concentration was measured for 336 infants and serum concentrations of iron, zinc, and retinol (vitamin A were measured for a stratified subsample of 55 infants. Anemia was defined using World Health Organization (WHO standards combined with the Chinese standard for infants Results We found that 35.12% of infants in rural Shaanxi suffered from anemia, and the malnutrition prevalence rates were 32.14% for underweight, 39.58% for stunting, and 11.31% for wasting. Anemia was significantly associated with malnutrition (underweight, OR: 2.42, 95%CI: 1.50-3.88; stunting, OR: 1.65, 95%CI: 1.05-2.61; wasting, OR: 2.89, 95%CI: 1.45-5.76. Low birth weight, more siblings, less maternal education, low family income, crowded living conditions, and inappropriate complementary food introduction significantly increased the risk for infant anemia. Serum concentrations of iron, zinc, and retinol (vitamin A were significantly lower in anemic infants compared with non-anemic infants. Conclusions Specific socio-demographic characteristics and feeding patterns were highly associated with infant anemia in rural areas of Shaanxi province. Health education focusing on feeding practices and nutrition education could be a practical strategy for preventing anemia and

    Ultraweak photon emission emitted by all living organisms has been confirmed to be a noninvasive indicator for their physiological and pathological characteristics. In this study, we investigated the characteristics of spontaneous photon emission (SPE) and the contents of specific active compounds of roots and flowers buds of several fresh Chinese herbal medicines (natural medicines) with different growth ages and varieties. The results revealed that the contents of specific active compounds from same species herbs with different growth ages and varieties were significantly different, and this difference could be reflected by their SPE. Because the contents of specific bioactive constituents in Chinese herbs are closely related to their quality and curative effect, the SPE measurement technique may contribute to the quality control of Chinese herbal medicine in the future.

    Following the 2008 Wenchuan earthquake, the Chinese government instituted an infant and young and child nutrition program that included promotion of in-home fortification of complementary food with ying yang bao (YYB), a soy-based powder containing iron, 2.5 mg as iron-EDTA and 5 mg as ferrous fumarate, and other micronutrients. Ying yang bao was provided to participating families in 8 poor rural counties in Sichuan, Shaanxi, and Gansu provinces by the Ministry of Health. We assessed hemoglobin levels among infants and young children (IYC) aged 6 to 23 months at baseline in May 2010 (n = 1290) and during follow-up in November 2010 (n = 1142), May 2011 (n = 1118), and November 2011 (n = 1040), using the Hemocue method. Interviewers collected basic demographic information and child feeding practices from the children's caretakers. Altitude-adjusted hemoglobin level averaged 10.8 g/dL, and total anemia prevalence was 49.5% at baseline. Average hemoglobin was 11.3 g/dL at 6 months, 11.6 g/dL at 12 months, and 11.7 g/dL at 18 months after introduction of YYB. Moderate anemia (hemoglobin: 70-99 g/dL) decreased from 20.3% at baseline to 7.5%, 5.8%, and 7.3% after 6, 12, and 18 months of home fortification, respectively (P regions of China.

    The relationship between thyroid dysfunction and metabolic syndrome (MS) is complex. We aimed to explore the impact of gender and age on their association in a large Chinese cohort. This cross-sectional study enrolled 13,855 participants (8532 male, 5323 female), who self-reported as healthy without any known previous diseases. Clinical data including anthropometric measurements, thyroid function, and serum metabolic parameters were collected. The associations between thyroid function and MS of both genders were analyzed separately after dividing thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), and age into subgroups. MS risks were calculated by binary logistic regression models. Young males had significantly higher MS prevalence than females, yet after menopause, females had higher prevalence than males. Females had higher incidence of thyroid dysfunction than males. By using TSH quartiles as the categorical variables and the lowest quartile as reference, significantly increased MS risk was demonstrated in quartile 4 for males, yet quartiles 3 and 4 for females. By using FT3 quartiles as the categorical variables, significantly increased MS risk was demonstrated in quartile 2 to 4 for females only. By using age subgroups as the categorical variables, significantly increased MS risk was shown in both genders, with females (4.408-58.455) higher than males (2.588-4.943). Gender and age had substantial influence on thyroid function and MS. Females with high TSH and high FT3 had higher MS risks than males. Aging was a risk for MS, especially for females. Urgent need is necessary to initiate interventional programs.

    To date, few works have attempted to determine the effect of soil types on Selenium aging process and the possible influential factors. In this study, the differences in Se speciation distribution and availability in 15 Chinese typical agricultural soils were investigated using spiked selenate for the entire year. Results evidenced that after one year of incubation, Se transformed from soluble fraction to Fe/Mn oxides and organic matter bound fractions in neutral or alkaline soils (pH 7.09-8.51) and from exchangeable fraction to residual fraction in acidic soils (pH 4.89-6.82). The available Se content in all soils declined rapidly at the initial stage of aging, with most of the neutral or alkaline soils reaching equilibrium after 109 d, whereas the acidic soils reached equilibrium after only 33-56 d. The available Se content in soil decreased constantly during the entire aging process in S4 (Xinjiang Gray desert soil), S12 (Anhui Yellow brown earths), and S15 (Hunan Krasnozems). Elovich model was the best model (R(2) > 0.80) in describing the Se aging process. Estimated time for exogenous Se reaching the distribution of available Se in corresponding native soils extended from 9.7 y to 50.2 y, indicating a much longer time was required for spiked soil to reach equilibrium. Soil pH was the most significant factor directly and negatively influencing the aging process (p speciation.

    The 234U/238U ratio of fine particles can record the time since their separation from bed rock because of the disruption of uranium series equilibrium introduced by the recoil of daughter 234Th nuclei (precursor of 234U) out of particle surfaces during the decay of 238U. Application of the uranium comminution age method, which has great potential in tracing production and transportation of sediments is however complicated by the weathering dissolution of 234U depleted particle surfaces, the difficulty in determining the fraction of recoiled nuclei, and the precipitation of exogenetic 234U. Here we minimize these complications by using a newly developed precise size separation using electroformed sieve, and a chemical protocol that involves reductive and oxidative leaching. Eolian deposits collected from the Chinese Loess Plateau (CLP) were used to test the validity of our method. Possible effects of weathering dissolution were also evaluated by comparing samples with different weathering intensities. The results show decreasing 234U/238U ratios in fine eolian particles with increasing sedimentation age, agreeing well with the theoretical prediction of the comminution age model. This successful application of the uranium comminution age approach to the eolian deposits on the CLP is also aided by a stable dust source, the low weathering intensity, the lack of consolidation, and the well-defined age model of the deposits. A transportation time of 242 ± 18 ka was calculated for the eolian deposits, which indicates a long residence time, and thus extensive mixing, of the dust particles in source regions, partly explaining the stable and homogeneous composition of the eolian dust over glacial-interglacial cycles.

    Tobacco products use is the leading cause of chronic diseases morbidity and mortality. This study explores an exposure to tobacco advertisements factors and knowledge, an association with snuff/pipe usage and cigarette smoking among Ellisras rural children aged between 11 to 18 years. A total of 1654 subjects (854 boys and 800 girls) who were part of the Ellisras Longitudinal Study completed the questionnaire. A significant (p < 0.05) number of boys (11.7%) compared to girls (8.8%) received free cigarettes from the members of the community. Bill boards were successful in advertising tobacco products among the Ellisras rural boys (17% boys and 12.8% for girls, p < 0.022). Multivariate analyses found significant association between cigarette smoking (OR = 1.7 95%CI 1.1-2.7 and Model 2 OR 1.6 95%CI 1.0-2.6 adjusted for age and gender) and advertisements of tobacco products on the TV screens, videos or movies. Exposure to tobacco products advertisements was high among Ellisras rural children. Though tobacco products legislation exists in South Africa, efforts should be taken by the health professionals to emphasize the danger of using tobacco products even among the illiterate. Teachers and parents should refrain from advertising tobacco products at schools and at homes.

    Full Text Available Introduction: Overweight and obesity have become leading causes of non-communicable diseases and millions of deaths worldwide every year are attributed to these conditions. Currently, diseases such as high blood pressure, strokes, type II diabetes, cancer among others, are attributable to overweight and obesity. This study sought to determine demographic and socioeconomic aspects associated with overweight and obesity among women residing in rural and urban areas of Zambia. It further examined the differences in factors that affect the prevalence of overweight and obesity among women residing in urban and those in rural areas of Zambia.  Methods: The study analysed the BMI from a total of (6967 urban and (7855 rural women using data from the 2013-14 Zambia Demographic and Health Survey (ZDHS. Both univariate and bivariate analyses were performed to describe the study population. Binary logistic regression analysis was used to examine the effect of demographic and socioeconomic factors on overweight and obesity among women in rural and urban areas of Zambia. Results: overweight and obesity prevalence were (21.2 percent and 10.8 percent among urban women versus (11.9 percent and 2.9 percent among rural women.  Age, region of residence, educational level and household wealth of women were significant predictors of both overweight and obesity among women regardless of place of residence.  Women in urban areas who resided in male headed households, had (4-6 children and drunk alcohol had higher odds of being overweight, whereas, women in male headed households only and reported having been drinking alcohol were associated with being obese. Literacy was found to be a major contributor of overweight among rural women. Conclusion: Overweight and obesity are markedly higher among urban women than rural women, and that differences on how these occur between these two groups of women have a socioeconomic and demographic dimension.

    Increased levels of C-reactive protein (CRP), common in aging populations, are associated with higher risk for chronic diseases, including diabetes and coronary heart disease. The aim of this study was to investigate associations between lifestyle factors and high CRP among middle-aged men living in Shanghai, China. In this cross-sectional study, 3978 urban Chinese men aged 40-74 years who were free of type-2 diabetes at baseline provided fasting blood samples, anthropometric measurements and information on lifestyle factors and disease history. Dietary patterns were assessed by factor analysis. Participants were categorised into two groups according to CRP level: normal (≤ 3 mg/L) and high (> 3 mg/L). Associations between CRP categories and lifestyle factors were investigated by using logistic regression. Obesity, weight gain, cigarette smoking and alcohol intake were positively associated with high CRP levels, while physical activity and a dietary pattern with high consumption of fruit were inversely related to high CRP levels. A positive trend of marginal significance between quintiles of a dietary pattern with high consumption of meat and high CRP levels was also observed. No association between tea intake and CRP level was observed. Components of an adverse lifestyle were associated with high CRP levels. Obesity, smoking and alcohol intake were associated with high CRP, a biomarker of low-grade inflammation in middle-aged men, while a dietary pattern rich in fruit and high physical activity were inversely associated with the prevalence of high CRP.

    OBJECTIVE Physical activity may modify the association of adiposity with type 2 diabetes. We investigated the independent and joint association of adiposity and physical activity with fasting plasma glucose, impaired fasting glucose, and type 2 diabetes in a Chinese population. RESEARCH DESIGN AND METHODS Middle-aged and older Chinese (n = 28,946, ≥50 years, 72.4%women) from the Guangzhou Biobank Cohort Study were examined in 2003–2008. Multivariable regression was used in a cross-sectional analysis. RESULTS BMI, waist circumference, and waist-to-hip ratio (WHR) were positively associated with type 2 diabetes after multiple adjustment, most strongly for WHR with odds ratio (OR) of 3.99 (95% CI 3.60–4.42) for highest compared with lowest tertile. Lack of moderate-to-vigorous physical activity, but not walking, was associated with diabetes with an OR of 1.29 (1.17–1.41). The association of moderate-to-vigorous activity with fasting glucose varied with WHR tertiles (P = 0.01 for interaction). Within the high WHR tertile, participants who had a lack of moderate-to-vigorous activity had an OR of 3.87 (3.22–4.65) for diabetes, whereas those who were active had an OR of 2.94 (2.41–3.59). CONCLUSIONS In this population, WHR was a better measure of adiposity-related diabetes risk than BMI or waist circumference. Higher moderate-to-vigorous activity was associated with lower diabetes risk, especially in abdominally obese individuals. PMID:20713687

METHODS: Among 60 Chinese patients with exudative AMD (60 eyes, 28 received intravitreal bevacizumab injections (1.25mg and 32 received intravitreal ranibizumab injections (0.5mg, once a month for 3 months and were followed for a total of 6 months. Monthly optical coherence tomography (OCT was used to determine whether the patients received additional treatments during the follow-up. We compared the baseline and 6-month follow-up values of mean best-corrected visual acuity (BCVA and central retinal thickness (CRT in both groups of patients. We also compared the occurrence of adverse events. RESULTS:At the 6-month follow-up, the mean BCVA (logMAR of the bevacizumab and ranibizumab treatment groups improved from the baseline measurements of 0.72±0.23 and 0.73±0.22 to 0.47±0.14 and 0.45±0.20, respectively (P<0.05 for both groups. However, the change was not significantly different between the two groups. As evaluated by OCT, CRT decreased from 366.71±34.72μm and 352±36.9μm at baseline to 250.86±41.51μm and 243.22±41.38μm in the bevacizumab and ranibizumab groups, respectively (P<0.05 for both groups. However, the change was not significantly different between the two groups. There were no severe local adverse reactions or systemic adverse events. CONCLUSION:Intravitreal bevacizumab and ranibizumab have equivalent effects on BCVA and CRT and appeare safe over the short-term.

    Qualitative research offers important insights into the subjectivity, complexity, and relationality of care. In this article, we examine the particular processes and relationships involved in doing qualitative research about care with older people in rural places. We draw on our experience completing two related qualitative studies of rural care in Canada to extend discussions about responsible research practice in relation to participant recruitment, interviews, and focus groups. By applying Hankivsky's principles of care ethics in our reflection on research practices, we make explicit the role of emotions in connecting with research participants, collecting and participating in narrative-based research, and negotiating identity. We conclude with a discussion of the distinct ways in which applying care ethics throughout the research process can augment reflexive practice and enhance the integrity and theoretical contributions of qualitative health research while developing more inclusive understandings of vulnerability in older rural populations.

    Epidemiologic studies have suggested that abortion may cause long term health consequences such as cardiovascular disease. Until recently, studies focusing on the association between history of abortion and metabolic diseases were limited. In the present study, we aimed to investigate the association between history of abortion and metabolic syndrome (MetS) in middle-aged and elderly Chinese women. A cross-sectional survey was performed in 6302 women (age ≥ 40 years) in Shanghai. Standardized questionnaire was used to obtain the information about reproductive histories. Overall, we observed a positive association between history of induced abortion and the prevalence of MetS, independent of potential confounding factors. A multivariable-adjusted logistic regression analysis revealed that compared to those without a history of induced abortion, women with a history of induced abortion remained at 1.25 times more likely to have MetS (OR = 1.25, 95% CI = 1.06-1.47, P abortion and the prevalence of MetS was observed. Compared to those without a history of spontaneous abortion, the multivariate-adjusted odds ratio associated with a history of spontaneous abortion for MetS was 0.88 (95% CI = 0.65-1.19, P > 0.05).

  19. Measures of Implicit Gender Attitudes May Exaggerate Differences in Underlying Associations among Chinese Urban and Rural Women

    Full Text Available The oppression of women in rural China is more severe than in urban China, not only because the two areas differ in terms of social hierarchy, but also because urban women are more likely to fight against their subordination, which is endorsed by conventional social views on gender. To independently assess these relationships, we applied the Quadruple Process model to measure the processes underlying implicit gender attitudes in a sample of urban and rural females. The results indicated that the urban women had higher in-group favoritism than did the rural women. Application of the Quad model, however, showed that pro-women associations were similarly activated among urban and rural women, but that women in rural settings more effectively inhibited activated associations. Differences in inhibition, rather than in activated associations, appear to account for the less favorable attitudes among rural women. Thus, the differences in attitudinal responses among urban and rural women exaggerate the differences in underlying evaluative associations with respect to gender and conceal differences in self-regulating the expression of those associations.

    Full Text Available Abstract Background Though non-communicable diseases contribute to an increasing share of the disease burden in South Asia, health systems in most rural communities are ill-equipped to deal with chronic illness. This analysis seeks to describe care-seeking behavior among women of reproductive age who died from fatal non-communicable diseases as recorded in northwest rural Bangladesh between 2001 and 2007. Methods This analysis utilized data from a large population-based cohort trial in northwest rural Bangladesh. To conduct verbal autopsies of women who died while under study surveillance, physicians interviewed family members to elicit the biomedical symptoms that the women experienced as well as a narrative of the events leading to deaths. We performed qualitative textual analysis of verbal autopsy narratives for 250 women of reproductive age who died from non-communicable diseases between 2001 and 2007. Results The majority of women (94% sought at least one provider for their illnesses. Approximately 71% of women first visited non-certified providers such as village doctors and traditional healers, while 23% first sought care from medically certified providers. After the first point of care, women appeared to switch to medically certified practitioners when treatment from non-certified providers failed to resolve their illness. Conclusions This study suggests that treatment seeking patterns for non-communicable diseases are affected by many of the sociocultural factors that influence care seeking for pregnancy-related illnesses. Families in northwest rural Bangladesh typically delayed seeking treatment from medically certified providers for NCDs due to the cost of services, distance to facilities, established relationships with non-certified providers, and lack of recognition of the severity of illnesses. Most women did not realize initially that they were suffering from a chronic illness. Since women typically reached medically certified

    Abstract This cross-sectional exploratory study aimed to quantify and compare the axial and appendicular bone mineral density (BMD), muscle mass, and muscle strength of middle-aged practitioners of Ving Tsun (VT; a hard-style Chinese martial art) with those of nonpractitioners. Eighteen VT practitioners (mean age ± standard deviation = 51.8 ± 17.7 years; 12 men and six women) and 36 active controls (mean age ± standard deviation = 58.7 ± 11.0 years; 18 men and 18 women) participated in the study. All participants underwent a 1-day battery of musculoskeletal examinations. The BMD of the total radius, total hip, femoral neck, and lumbar spine was measured using dual-energy X-ray absorptiometry, as was the lean mass of the arm, leg, and trunk. Muscle strength of the upper and lower limbs was assessed using a Jamar dynamometer and an isokinetic dynamometer at 60°/second, respectively. VT-trained participants had a 11.5% higher total radius BMD (P = 0.023), a 17.8% higher leg lean mass (P = 0.014), a 56.4% higher isokinetic body weight-adjusted peak torque of the knee extensors (P  0.05). Middle-aged VT practitioners displayed a higher total radius BMD and leg lean mass and better knee extensor and flexor muscular performances than their healthy active counterparts. Healthcare professionals may consider using this alternative method of training to improve the musculoskeletal health of middle-aged adults. PMID:28121945

    While Western discourses regarding productive aging emphasize individuals' contributions to economic productivity, the Confucian cultural heritage of the Chinese community may provide an alternative perspective. This qualitative study explores interpretations of what constitutes productive aging, based on a series of in-depth interviews with older Chinese people in Hong Kong. It shows that some of these individuals adopted a passive and indirect interpretation of productive aging, distinct from that found in Western countries. The Confucianism-based, collectivist, normative order underpinning Hong Kong society disposed these older people to adopting a self-restrained attitude with the aim of avoiding becoming a burden to others, especially family members. Such a tendency toward self-restraint or avoidance also encompassed a compromise between ideals and reality, with the older people opting to compromise their expectations of the younger generation as a whole, their adult children in particular, in terms of respect and reciprocity.

    . MATERIAL AND METHODS: A cross-sectional, descriptive study was conducted between February and October 2002, in a convenience sample of 392 elderly men residing in rural areas of the states of Guerrero, Morelos and Jalisco states. A validated questionnaire was applied to collect data on sociodemographic characteristics, general wellbeing, health problems, food consumption, and some indicators of mental health, personal strength and social support. Data analysis was performed with the SPSS v. II.1 software, to obtain chi-squared tests; food intake measures were analized with one-way ANOVA. RESULTS: Study subjects were married or were widowers and had six children on average. A higher proportion of the elderly men of Morelos state reported to have suffered more illnesses and a higher consumption of alcohol when compared to the other two state groups. Sixty percent of the men in the study used both home remedies and medication for their health problems. More than one half of them did not receive adequate social support from their families. CONCLUSIONS: The results of this study suggest that the process of ageing among rural elderly men is perceived as a burden, mainly because of the context of poverty in which they live. The lack of appropriate income and access to health services through adequate pension and retirement plans for the elderly poor is a problem that requires immediate attention.

    The ability to detect changing visual information is a vital component of safe driving. In addition to detecting changing visual information, drivers must also interpret its relevance to safety. Environmental changes considered to have high safety relevance will likely demand greater attention and more timely responses than those considered to have lower safety relevance. The aim of this study was to explore factors that are likely to influence perceptions of risk and safety regarding changing visual information in the driving environment. Factors explored were the environment in which the change occurs (i.e., urban vs. rural), the type of object that changes, and the driver's age, experience, and risk sensitivity. Sixty-three licensed drivers aged 18-70 years completed a hazard rating task, which required them to rate the perceived hazardousness of changing specific elements within urban and rural driving environments. Three attributes of potential hazards were systematically manipulated: the environment (urban, rural); the type of object changed (road sign, car, motorcycle, pedestrian, traffic light, animal, tree); and its inherent safety risk (low risk, high risk). Inherent safety risk was manipulated by either varying the object's placement, on/near or away from the road, or altering an infrastructure element that would require a change to driver behavior. Participants also completed two driving-related risk perception tasks, rating their relative crash risk and perceived risk of aberrant driving behaviors. Driver age was not significantly associated with hazard ratings, but individual differences in perceived risk of aberrant driving behaviors predicted hazard ratings, suggesting that general driving-related risk sensitivity plays a strong role in safety perception. In both urban and rural scenes, there were significant associations between hazard ratings and inherent safety risk, with low-risk changes perceived as consistently less hazardous than high

    Full Text Available Sustained forest management of Cunninghamia lanceolata (Chinese fir plantations in subtropical China is restricted by the limited availability of quantitative data. This study combines inventory data and tree-ring analysis of Chinese fir from natural and plantation forests that were subjected to controlled burning or brush clearing site preparations. Inter-annual variation of Chinese fir tree-ring widths were measured for the controlled burning, brush clearing and natural forest sites. The mean annual diametric growth of Chinese fir was 0.56 cm·year−1 for the natural forest, 0.80 cm·year−1 for the brush clearing site and 1.10 cm·year−1 for the controlled burning site. The time needed to reach the minimum cutting/logging diameter of 15 cm was 14 years in the controlled burning site, 19 years in the brush clearing site and >40 years in the natural forest. The biological rotation ages for the burning, cutting and natural forest sites were 15, 26 and >100 years, respectively. The total aboveground biomasses for the burning and clearing sites were 269.8 t·ha−1 and 252 t·ha−1, respectively. These results suggest that the current 25-year cutting cycle greatly underestimates the growth rate of Chinese fir plantations.

    Full Text Available Background: With the influx of rural migrants into urban areas, the spread of HIV has increased significantly in Shaanxi Province (China. Migrant workers are at high risk of HIV infection due to social conditions and hardships (isolation, separation, marginalization, barriers to services, etc.. Objective: We explored the efficacy of a HIV/AIDS prevention and control program for rural migrants in Shaanxi Province, administered at both rural and urban sites. Methods: Guidance concerning HIV/AIDS prevention was given to the experimental group (266 migrants for 1 year by the center of disease control, community health agencies and family planning department. The intervention was conducted according to the HIV/AIDS Prevention Management Manual for Rural Migrants. A control group of migrants only received general population intervention. The impact of the intervention was evaluated by administering HIV/AIDS knowledge, attitudes and sexual behavior (KAB questionnaires after 6 and 12 months. Results: In the experimental group; 6 months of intervention achieved improvements in HIV/AIDS related knowledge. After 12 months; HIV/AIDS-related knowledge reached near maximal scores. Attitude and most behaviors scores were significantly improved. Moreover; the experimental group showed significant differences in HIV-AIDS knowledge; attitude and most behavior compared with the control group. Conclusions: The systematic long-term cross-site HIV/AIDS prevention in both rural and urban areas is a highly effective method to improve HIV/AIDS KAB among rural migrants.

    Full Text Available Abstract Nutrition support programs that only focus upon better complementary feeding remain an insufficient means of limiting growth faltering in vulnerable populations of children. To determine if symptoms of acute infections correlate with the incidence of growth faltering in rural Malawian children, the associations between fever, diarrhea, and cough with anthropometric measures of stunting, wasting, and underweight were investigated. Data were analyzed from a trial where 209 children were provided with adequate complementary food and followed fortnightly from 6-18 months of age. Linear mixed model analysis was used to test for associations. Diarrheal disease was inversely associated with changes in height-for-age Z-score (HAZ, mid-upper arm circumference Z-score (MUACZ, and weight-for-age Z-score (WAZ. Fever was also inversely associated with changes in MUACZ and WAZ. These results suggest that initiatives to reduce febrile and diarrheal diseases are needed in conjunction with improved complementary feeding to limit growth faltering in rural Malawi.

The objectives of this study were to determine the prevalence of stunting for children and its association with three major soil-transmitted helminths (STH in rural areas of southern China. The study also aims to determine risk factors for stunting and to provide guidance on the prevention and control of stunting and STH infections for future studies in this field. Results A cross-sectional survey was carried out in the poor rural areas in Guangxi Autonomous Regional and Hainan Province where STH prevalence was higher between September and November 2009. Pupils were from 15 primary schools. All the school-age pupils aged between 9 and 12 years old (mean age 11.2 ± 3.2 years, from grades three to six took part in this study. Study contents include questionnaire surveys, physical examination and laboratory methods (stool checking for eggs of three major STH infections and haemoglobin determination was performed for the anaemia test. Finally 1031 school-age pupils took part in survey. The results showed that the overall prevalence of stunting (HAZ Conclusion The present study showed that stunting was highly prevalent among the study population and STH infection is one of the important risk factors for stunting, with moderate-to-heavy intensity infections being the main predictor of stunting. Hence, additional interventions measures such as to promote de-worming treatment, to enhance health education and to improve hygiene and sanitation in order to reduce stunting in this population, are needed throughout the primary school age group.

    To identify the trends of vegetables and fruits consumption among Chinese adults aged 18 to 44 years old from 1991 to 2011. Twenty four hour dietary recall data from China Health and Nutrition Survey (1991, 1993, 1997, 2000, 2004, 2006, 2009 and 2011) were used to identify the trends of vegetables and fruits consumption among Chinese between 18 and 44 years old. From 1991 to 2011, the proportion of daily consumption of vegetables rarely varied, while the vegetables intake declined significantly; and the proportion of daily consumption and intake of fruits kept increasing as follows. By 2011, the proportion of daily consumption and intake of vegetables and fruits among the respondents were 99.7%, 48.0%, 321.6 g/d, and 90.1 g/d respectively. A significant drop was found in the vegetables intake among the respondents against the vegetables intake as recommended by the Chinese dietary guidelines, up to 50.2% in 2011; a significant rise was found in the fruits intake of the respondents against the fruits intake as recommended by the said guidelines, up to 17.4% in 2011. The average daily intake of vegetables and fruits of young and middle-aged residents (18-44 age group) in nine provinces in China was found lower than that recommended in the Chinese dietary guidelines; in view of the high proportion of people having less vegetables and fruits intake that those recommended by the Chinese dietary guidelines, further measures are expected to encourage their vegetables and fruits intake.

    Bacterial vaginosis (BV) is one of the most common urogenital infections among women of reproductive age that represents shifts in microbiota from Lactobacillus spp. to diverse anaerobes. The aim of our study was to evalute the diagnostic values of Gardnerella, Atopobium, Eggerthella, Megasphaera typeI, Leptotrichia/Sneathia and Prevotella, defined as a vaginal pathogenic community for BV and their associations with vaginal pH and Nugent scores. We investigated the vaginal pathogenic bacteria and Lactobacillus spp. with species-specific real-time quantitative PCR (qPCR) in 50 BV-positive and 50 BV-negative Chinese women of reproductive age. Relative to BV-negative subjects, a siginificant decline in Lactobacillus and an obvious increase in bacteria in the vaginal pathogenic community were observed in BV-postive subjects (P<0.05). With the exception of Megasphaera typeI, other vaginal pathogenic bacteria were highly predictable for BV with a better sensitivity and specificity. The vaginal pathogenic community was positively associated with vaginal pH and Nugent scores, while Lactobacillus spp., such as L. iners and L. crispatus was negatively associated with them (P<0.05). Our data implied that the prevalance of vaginal pathogenic bacteria as well as the depletion of Lactobacillus was highly accurate for BV diagnosis. Vaginal microbiota shifts, especially the overgrowth of the vaginal pathogenic community, showed well diagnostic values in predicting BV. Postive correlations between those vaginal pathogenic bacteria and vaginal pH, Nugent score indicated the vaginal pathogenic community rather than a single vaginal microorganism, was participated in the onset of BV directly.

    因为衰老而导致的干细胞功能缺陷会影响组织的稳态,并最终导致机体寿命缩短。干细胞具有自我更新和增殖分化能力,在机体生长发育过程中对组织的自我修复及再生无疑是至关重要的。成体干细胞中研究比较透彻的干细胞是造血干细胞(HSCs),但是对其自身衰老调控的机制尚不清楚。表观修饰的改变被认为是哺乳动物衰老的标志之一,并且参与了HSCs 的衰老过程。另外,近期的研究发现HSCs 的衰老与血液肿瘤密切相关,因此表观遗传调控者或许可以成为治疗血液肿瘤的新靶点。长久以来中药一直被用于治疗血液肿瘤并且疗效确切,比如三氧化二砷。在这篇综述中,我们总结了表观修饰改变与HSCs 衰老的关系,并且重点论述了DNA 甲基化及组蛋白修饰调控HSCs 衰老的机制。我们还总结了目前用于治疗血液肿瘤的部分中药,并对其表观遗传调控的角色进行了论述,旨在为开发新的药物提供依据。%Age-related defects in stem cells can limit proper tissue maintenance and hence contribute to a shortened lifespan. Given the essential role of a stem cell to self-renew, differentiate, and proliferate, it is no wonder that they are critically important to an organism during development and to tissue self-healing and regeneration. Hematopoietic stem cells (HSCs), as one of adult stem cells, have been well characterized recently. However, the regulation mechanism of HSCs ageing remains unclear. Epigenetic alterations are now recognized as a hallmark of mammalian ageing and involved in HSCs ageing. In addition, recent studies showed that HSCs ageing is related to hematological malignancies. Therefore, epigenetic modifiers maybe novel targets for hematological malignancies therapy. Traditional Chinese medicine (TCM) has been used to treat hematological malignancies for centuries. Here, we aim to review the current progress in the

    Spirulina is an alga rich in high-quality protein and carotenoids. It is unclear whether spirulina can improve the total-body vitamin A stores of school-age children in China with a high prevalence of vitamin A malnutrition. We aimed to evaluate the efficacy of spirulina in improving the total-body vitamin A stores of school-age children in rural areas of China when they consumed spirulina in their daily meals. A total of 228 children (6-11 years) were recruited and randomly divided into three groups supplemented with 4 g (containing 4·18 µg β-carotene), 2 g (containing 2·54 µg β-carotene) or 0 g spirulina 5 d/week for 10 weeks, respectively. Before and after the intervention period, each child was given 0·5 mg [(2)H4]retinyl acetate and [(2)H8]retinyl acetate, respectively. To assess vitamin A stores, blood samples (3 ml) were collected on the third and the twenty-first day after each labelled retinyl acetate dose for a retinol enrichment analysis using a GC mass spectrometer. The concentrations of retinol and β-carotene in serum samples were also determined by using HPLC. After the 10-week intervention, serum β-carotene concentrations of children with 2 or 4 g spirulina supplement increased by 0·160 and 0·389 µmmol/l, respectively. Total-body vitamin A stores increased significantly, with a median increase of 0·160 mmol in children taking 2 g spirulina and of 0·279 mmol in children taking 4 g spirulina. Spirulina is a good dietary source of β-carotene, which may effectively increase the total-body vitamin A stores of Chinese school-age children.

    Recent work (Watanuki et al., submitted) has shown by comparison with independent age control that silt-sized quartz grains extracted from Japanese loess can be used for optically stimulated luminescence (OSL) dating for equivalent doses of up to 425 Gy (˜500 ka at these sites). Further comparison with infrared (IR) stimulated and post-IR blue-stimulated OSL showed that the latter signal gave accurate ages, and was probably dominated by quartz, whereas the former systematically underestimated ages in the range 30-600 ka, and showed fading in laboratory tests. The main source of the loess deposits in Japan is the Chinese mainland; in eastern Asia, loess is widely distributed by the prevailing westerly winds, and one of the main sources is in the western desert areas of China. Unfortunately, independent age control is very unusual in loess deposits in China, and there is little evidence for the accuracy of existing luminescence ages from this material. As an alternative approach, this study builds on the Japanese results by using loess from two Chinese sites, and examining the relationship between single-aliquot regeneration dose IR and post-IR blue-stimulated luminescence ages from polymineral samples, and blue-stimulated quartz luminescence ages. The normalized blue-stimulated OSL intensity from quartz from the eastern site was about 10 times that from the west, suggesting either a different source of material, or (less likely) an increase in quartz sensitivity with transport distance. By comparison with quartz results we conclude that, in our samples of Chinese loess, the post-IR blue-stimulated OSL is the more reliable polymineral signal, when compared with the IR signal. It may nevertheless include a feldspar component, and this should be tested for using laboratory fading experiments.

    This paper draws upon qualitative research conducted among older adults in the rural, southern United States in which they articulated their beliefs and experiences with nutrition and foods, and lay models of the connection of diet with chronic disease. Salt emerged as a focus of contention. The goals of the paper are to (1) present the culturally constructed meaning of salt, (2) contrast the cultural meaning with biomedical views, and (3) discuss how these findings can be applied to health education and better doctor-patient communication. Data were collected in two rural communities characterized by high rates of poverty and a high proportion of minority residents. A total of 116 African American, Native American and white adults aged 60 years and older participated in 55 in-depth interviews or seven focus groups. A systematic analysis of text showed that salt was a highly contested component of food. While valued for its role in traditional foods and cuisine, it also held negative connotations because of biomedical links to chronic diseases prevalent in the population. We suggest that attempts to control salt intake are made difficult by the changes in taste perceptions that accompany aging. Respondents' articulation of salt's role in health and disease shows cross-over among different chronic diseases and a lay interpretation of blood as the medium through which salt affects disease. These older adults' narratives demonstrate their attempts to reconcile the important role of traditional foods in their identity as Southerners with their attempts to meet medical recommendations for healthy eating.

    Nutritional status of school-aged children has an important impact on their physical and mental development. Data on anemia, thinness and wasting among school-aged Sudanese children were limited. To determine the prevalence of anemia, thinness and wasting among school-aged Sudanese children. This cross-sectional study enrolled 835 primary school children aged 6-14 years, who live in Dolgo area in the northern region of Sudan. Weight and height of each child were measured and body mass index (BMI) was calculated. All measurements were plotted on the World Health Organization (WHO) height for age and BMI charts. Hemoglobin was also measured for all participants, and anemia was defined according to the WHO standards. Anthropometric measurements showed that 59 children (7.1%) were stunted and 193 were thin (23.1%). The prevalence of anemia was 29.7%. Stunting, thinness and anemia were significantly common in children anemia among school-aged children in a rural area in Sudan. Our findings warrant the need to implement interventions to improve nutritional status of children in Sudan. © The Author [2015]. Published by Oxford University Press. All rights reserved.

    Chromosome malsegregation in binucleated lymphocytes is a useful endpoint to evaluate age effect on genetic stability. However, the investigations on chromosome malsegregation in binucleated lymphocytes from Chinese are scarce. In this study, peripheral blood lymphocytes were collected from 14 old (60-70 years) and 10 young (22-26 years) healthy Chinese men. To detect malsegregation of the sex chromosomes, multi-color fluorescence in situ hybridization (FISH) was performed on binucleated lymphocytes, cytokinesis-blocked by cytochalasin B at the first mitosis after phytohaemagglutinin stimulation. Compared with that in young men, a significant increase in frequencies of loss of chromosome X (9.2 +/- 3.2 per thousand vs. 1.1 +/- 0.9 per thousand, P men. Similarly, nondisjunction of chromosome X (16.5 +/- 3.4 per thousand vs. 3.5 +/- 1.1 per thousand, P men than in young men. Regardless of donor's age, nondisjunction is more prevalent than loss for both chromosome X and Y. The frequencies of observed simultaneous malsegregation were relatively higher than the expected, suggesting an association between malsegregation. These results indicated that in Chinese men, malsegregation of the sex chromosomes increases with age in an associated fashion, and nondisjunction accounts for the majority of spontaneous chromosome malsegregation.

    The number of internal migrant children in China has reached 35.8 million by the end of 2010. Previous studies revealed inconsistent findings regarding the mental health status of rural-to-urban migrant adolescents, as well as the impact of peer, teacher and parental support on the mental health of Chinese adolescent migrants. Using a comparative approach, this study attempted to compare the mental health status between migrant and urban-born adolescents and to clarify the specific roles of different sources of social support in the mental health of migrant and urban adolescents. A cross-sectional survey using a cluster convenience sampling strategy was performed in Beijing, China. A structured questionnaire was filled out by 368 rural-to-urban migrant adolescents and 325 urban-born adolescents. A significant difference was found only for positive affect (PA) but not for negative affect (NA) between the two groups, favouring the urban-born adolescents. Social support from all the three sources were all predictive of PA among rural-to-urban migrant adolescents, while only peer support contributed to PA among urban-born adolescents. Unexpectedly, teachers' support contributed to an increase in NA among urban-born adolescents. The findings contribute to understanding of the mental health status of migrant adolescents in China and the differential impact of the various sources of social support on migrant and urban-born adolescents. Also the findings may inform the development of mental health services and programmes that can potentially benefit a large number of internal migrant adolescents in China.

    Sumedh Bele

    Full Text Available BACKGROUND: Tuberculosis is a serious global health problem. Its paradigms are shifting through time, especially in rapidly developing countries such as China. Health providers in China are at the forefront of the battle against tuberculosis; however, there are few empirical studies on health providers' perspectives on the challenges they face in tuberculosis control at the county level in China. This study was conducted among health providers to explore their experiences with tuberculosis control in order to identify bottlenecks and emerging challenges in controlling tuberculosis in rural China. METHODS: A qualitative approach was used. Semi-structured, in-depth interviews were conducted with 17 health providers working in various positions within the health system of one rural county (ZJG of China. Data were analyzed based on thematic content analysis using MAXQDA 10 qualitative data analysis software. RESULTS: Health providers reported several problems in tuberculosis control in ZJG county. Migrant workers and the elderly were repeatedly documented as the main obstacles in effective tuberculosis control in the county. At a personal level, doctors showed their frustration with the lack of new drugs for treating tuberculosis patients, and their opinions varied regarding incentives for referring patients. CONCLUSION: The results suggest that several problems still remain for controlling tuberculosis in rural China. Tuberculosis control efforts need to make reaching the most vulnerable populations a priority and encourage local health providers to adopt innovative practices in the local context based on national guidelines to achieve the best results. Considerable changes in China's National Tuberculosis Control Program are needed to tackle these emerging challenges faced by health workers at the county level.

    Objective: To evaluate the vitamin D nutritional status in Chinese women of child-bearing age by analyzing serum 25-hydroxyvitamin D level in 2010-2012. Methods: Data were obtained from the China Nutrition and Health Survey in 2010-2012. Using cluster sampling and proportional stratified random sampling, 1 514 women of child-bearing age (18-44 years old) from 34 metropolis and 41 small and medium-sized cities were included in this study. Demographic information was collected by questionnaire and serum 25-hydroxyvitamin D concentration was determined by radioimmunoassay, in accordance with the 2010 Institute of Medicine of the National Academies standards. We compared differences in vitamin D levels, specifically serious deficiency, lack of deficiency, insufficiency, and excess. Results: The overall serum 25-hydroxyvitamin D level of Chinese urban women of child-bearing age (P(50) (P(25)-P(75))) was 20.1 (15.1-26.3) ng/ml; minorities had a significantly higher serum 25-hydroxyvitamin D level of 22.0 (15.9-27.5) ng/ml compared with women of Han nationality (19.8 (14.9-26.2) ng/ml) (χ(2)=7.02, P=0.008). The proportions of women with serious deficiency, lack of deficiency, insufficiency, and excess vitamin D were 11.6% (n=175), 37.9% (n=574), 35.1% (n=531), and 0.3% (n=5), respectively. Only 15.1% (n=229) of women of child-bearing age had normal vitamin D nutritional status. No significant differences in vitamin D nutritional status were observed according to age, body mass index, city, nationality, educational level, marital status, or household income per capita (P>0.05). Conclusion: Most Chinese urban women of child-bearing age have poor vitamin D levels and require vitamin D supplementation.

    Risk of type 2 diabetes mellitus (T2DM) is increased in metabolically obese but normal-weight people. However, we have limited knowledge of how to prevent T2DM in normal-weight people. We aimed to evaluate the association between triglyceride glucose (TyG) index and incident T2DM among normal-weight people in rural China. We included data from 5706 people with normal body mass index (BMI) (18.5-23.9 kg/m(2)) without baseline T2DM in a rural Chinese cohort followed for a median of 6.0 years. A Cox proportional-hazard model was used to assess the risk of incident T2DM by quartiles of TyG index and difference in TyG index between follow-up and baseline (TyG-D), estimating hazard ratios (HRs) and 95% confidence intervals (CIs). A generalized additive plot was used to show the nonparametric smoothed exposure-response association between risk of T2DM and TyG index as a continuous variable. TyG was calculated as ln [fasting triglyceride level (mg/dl) × fasting plasma glucose level (mg/dl)/2]. Risk of incident T2DM was increased with quartiles 2, 3 and 4 versus quartile 1 of TyG index (adjusted HR [aHR] 2.48 [95% CI 1.20-5.11], 3.77 [1.83-7.79], and 5.30 [2.21-12.71], P trend Risk of incident T2DM was increased with quartile 4 versus quartile 1 of TyG-D (aHR 3.91 [2.22-6.87]). The results were consistent when analyses were restricted to participants without baseline metabolic syndrome and impaired fasting glucose level. The generalized additive plot showed cumulative increased risk of T2DM with increasing TyG index. Risk of incident T2DM is increased with increasing TyG index among rural Chinese people, so the index might be an important indicator for identifying people at high risk of T2DM.

    Financial subsidy mechanism is tile biggest difference between the new and the old rural social old-age insurance, and whether the financial support capability is sustainable or not is the key to the sustainable development of new rural social old-age insurance system. Thus, studying the topic of new rural social old-age insurance financial support capability is of great practical significance. An important indicator to evaluate whether finance has the ability to support the new rural social old-age insur- ance or not, is the proportion of new rural old-age insurance annual financial subsidy amount to the same level government annual fiscal revenue. This paper select the proportion of annual central finance's new rural old-age insur- ance subsidy to the annual central fiscal revenue, and the proportion of annual local finance's new rural old-age in- surance subsidy to the annual local fiscal revenue such two indicators to estimate and analyze the new rural social old-age insurance financial support capability. The estimated time is from 2010 to 2030, and the estimated time is policy simulation. In order to make a simulation estimation, it needs to predict future relative data. This paper simulates and pre- dicts Chinese total rural population data and its structure data, the total fiscal revenue data and its structure data, the population coverage of new rural social old-age insurance, minimum basic pension standard and minimum pay- ment standard from 2010 to 2030. And then, it estimates the proportion of annual central finance's new rural social old-age insurance subsidy to the annual central fiscal revenue, and the promotion of annual local finance's new rural social old-age insurance subsidy to the annual local fiscal revenue from 2010 to 2030.%财政补贴机制是新农保与老农保的最大区别,财政保障能力能否可持续是新农保制度可持续发展的关键。本文通过模拟预测2010—2030年中国农村人口、财政收入、

    Xiaobing Wang

    Full Text Available We conducted a survey of 1707 children in 141 impoverished rural areas of Guizhou and Sichuan Provinces in Southwest China. Kato-Katz smear testing of stool samples elucidated the prevalence of ascariasis, trichuriasis and hookworm infections in pre-school and school aged children. Demographic, hygiene, household and anthropometric data were collected to better understand risks for infection in this population. 21.2 percent of pre-school children and 22.9 percent of school aged children were infected with at least one of the three types of STH. In Guizhou, 33.9 percent of pre-school children were infected, as were 40.1 percent of school aged children. In Sichuan, these numbers were 9.7 percent and 6.6 percent, respectively. Number of siblings, maternal education, consumption of uncooked meat, consumption of unboiled water, and livestock ownership all correlated significantly with STH infection. Through decomposition analysis, we determined that these correlates made up 26.7 percent of the difference in STH infection between the two provinces. Multivariate analysis showed that STH infection is associated with significantly lower weight-for-age and height-for-age z-scores; moreover, older children infected with STHs lag further behind on the international growth scales than younger children.

    This paper presents the results of anthropometric assessment of 2,364 boys and 2,415 girls aged 18 years and below drawn from the estates and rural community groups engaged in padi farming, rubber planting, coconut cultivation and fishing. The children were mainly Malay, however in the estates, Indians predominated. The results showed that the percentage of boys who have normal weight-for-age, height-for-age and weight-for-height were respectively 69.4%, 68.3% and 88.8%. Among girls, the percentage with normal values for weight-for-age, height-for-age and weight-for-height were 73.8%, 72.6% and 89.5% respectively. This study also showed the persistence of underweight, stunting and wasting amongst children in the study communities. Overall, the prevalence of underweight among boys was 29.8% and for girls 25.5%. The prevalence of stunting was 31.3% for boys and 26.9% for girls, while wasting was found in 9.3% boys and 8.5% girls. By age groups, the prevalence of underweight was lowest among the infants (16.8% for boys and 13.3% for girls), and highest among children aged above 1 to 6 years old (32.6% and 35.9% for boys and girls respectively). Children from the fishing, rubber and padi villages showed a higher prevalence of acute and chronic undernutrition than those from the coconut and the estate communities. In contrast, the mean prevalence of overweight in the five community groups did not exceed 2%. When compared with another peninsula-wide nutritional assessment of poverty villages undertaken in 1979-1983, it is found, over the past decade, that the prevalence of underweight in rural communities appeared to have decreased somewhat while that of stunting showed a more substantial decline. The persistence of current undernutrition has led to the manifestation of children who were too thin for their "non-stunted" height, thus giving rise to an apparently higher prevalence of wasting as found in this study. The implications of these results are discussed.

    Self-neglect and suicidal ideations are important public health issues among the aging population. This study aims to examine the association between self-neglect, its phenotypes, and suicidal ideation among U.S. Chinese older adults. Guided by a community-based participatory research approach, the Population Study of Chinese Elderly in Chicago (PINE) study is a population-based epidemiological study conducted from 2011 to 2013 among 3,159 Chinese older adults aged 60 years and older in the Greater Chicago area. Self-neglect was assessed by a 27-item instrument, describing five phenotypes with hoarding, poor personal hygiene, unsanitary condition, lack of utilities, and need of home repair. Suicidal ideation was assessed by the ninth item of the Patient Health Questionnaire-9 (PHQ-9) and the Geriatric Mental State Examination-Version A (GMS-A). Logistic regression is utilized to analyze the association. Higher level of self-neglect was found significantly associated with increased risk of self-reported suicidal ideation within 2 weeks (odds ratio 2.97 [1.54-5.72]); 12 months (odds ratio 2.82 [1.77-4.51]); and lifetime (odds ratio 2.74 [1.89-3.95]). For phenotypes, the study found that poorer personal hygiene and severer level of unsanitary conditions were associated with increased risk of suicidal ideation at all three time periods. This study suggests that self-neglect and its phenotypes are significantly associated with suicidal ideation among Chinese older adults. Longitudinal studies are needed to explore the mechanisms through which self-neglect links with suicidal ideation.

    To evaluate the possible relationship between self-reported history of abortion and nonalcoholic fatty liver disease (NAFLD) in middle-aged and elderly Chinese women. A cross-sectional study was performed in 5911 women aged 40 years or older in Jiading District, Shanghai, China. Reproductive histories, including miscarriage and induced abortion, were collected using a validated questionnaire by trained physicians. Abdominal B-mode ultrasound evaluation and serum liver enzymes levels were used in the diagnosis of NAFLD. The percentage reporting history of abortion in women with NAFLD was higher than in those without NAFLD (72.4% vs. 69.3%, age-adjusted P = .001). Compared with women without a history of abortion, the fully adjusted odds ratio (OR) for NAFLD in those with a history of abortion was increased by 28% (OR, 1.28 and 95% confidence interval [CI], 1.06-1.55). Histories of miscarriage and induced abortion were also associated with increased risk of prevalent NAFLD in fully adjusted models (OR, 1.84 and 95% CI, 1.24-2.72; OR, 1.23 and 95% CI, 1.02-1.50, respectively). Both miscarriage and induced abortion are associated with prevalent NAFLD in middle-aged and elderly Chinese women. Copyright © 2013 Elsevier Inc. All rights reserved.

    Some scholars argue that the maintenance of social networks contributes to the lower prevalence of deviant behaviours and fewer adverse health effects among migrants. But others suggest that if migrants are embedded in homogeneous networks, such networks may enable the formation of a deviant subculture that promotes risk taking. Facing this dilemma, the present study investigates how native-place networks influence sexual risk behaviours (SRBs), specifically the pursuit of commercial sex and condomless sex with sex workers, for male rural-urban migrants. Using a multi-stage sample of 1,591 male rural-urban migrants from two major migrant-influx cities within China, we assessed migrants' general friend network ties and native place networks (townsmen in migrants' local networks) and tested their associations with SRBs. Multiple logistic regression analyses indicate that native-place network ties are associated with paying for sex (OR = 1.33, p rural-urban migrants are associated with SRBs because homogenous networks may serve as a platform for the emergence of a deviant subculture that promotes risk behaviours.

Methods: Records of traffic injuries in people over 60 years old registered by the traffic police between 2000 and 2006 in Nan’an district and Jiangjin district were collected in the Database of Road Traffic Accidents and Traffic Injuries. Epidemiologic characteristics of traffic injuries among the aged people were analyzed and compared. Results: Between the year 2000 and 2006, the average annual incidence of traffic injuries and mortality rate in the aged people in Nan’an district were 124.62/100 000 and 13.85/ 100 000 respectively, higher than that in Jiangjin district (27.49/ 100 000, 7.13/100 000, P<0.01. However, the mortality rate for the aged people who were involved in traffic injuries in Jiangjin district was 20.60%, higher than that in Nan’an district (10.00%, P<0.01. Head injury was the primary cause of death. Totally 76.58% of casualties were pede-strians. Over 90% of the traffic accidents occurred in the areas with no traffic signal or traffic control system. Conclusions: The traffic environment is unfavorable to the aged people. It is important to enhance traffic safety consciousness of drivers and the elderly and to strengthen traffic safety system and traffic law, so as to provide a safe road traffic environment for the aged people.

    To investigate the etiological spectrum of moderate to severe visual impairment and blindness in population aged 50 years or more in rural Shandong province, China. A population based, random cluster sampling was used to screening the adults aged 50 years or more living in rural Shandong Province from April to July 2008. Three counties and one suburb representing the different levels of socioeconomic development within Shandong area were selected as the investigated areas. Geographically defined cluster sampling was used in randomly selecting a cross-section of residents aged ≥ 50 years from each county. Best corrected visual acuity and intra-ocular pressure were evaluated in those with presenting visual acuity ≤ 0.5 and suspected glaucoma respectively. The major causes of visual impairment and blindness were diagnosed in those with presenting visual acuity ≤ 0.3. According to the results of presenting visual acuity and best corrected visual acuity, the etiology constituent ratios of the moderate to severe visual impairment and blindness were analyzed respectively. According to the number of people, the first three principal causes for blindness based on the presenting visual acuity were cataract (59.8%, 168/281), fundus disease (12.1%, 34/281) and corneal opacity (4.3%, 12/281) or ametropia (4.3%, 12/281). The first three principal causes for moderate to severe visual impairment and blindness were cataract (55.2%, 844/1530), uncorrected refractive error (18.2%, 278/1530) and fundus disease (11.9%, 182/1530). Based on the best corrected visual acuity, the first three principal causes for blindness were cataract (64.6%, 153/237), fundus disease (10.5%, 25/237) and corneal opacity (4.7%, 11/237), respectively. The first three principal causes for moderate to severe visual impairment and blindness were cataract (66.4%, 590/889), fundus disease (16.0%, 142/889) and optic nerve atrophy (3.0%, 27/889).

    Carotid plaque (CP) is associated with cardiovascular and cerebrovascular events. However, population-based studies with a large sample are rare in China, particularly those in the low-income population. We aimed to determine the prevalence of CP and the associated risk factors in the rural areas of northern China. Between April 2014 and June 2014, we recruited 3789 residents aged ≥45 years. B-mode ultrasonography was performed to measure the extent of CP. The prevalence of CP was 40.3% overall, 47.1% in men, and 35.4% in women (P < 0.001). The prevalence of CP increased with increasing age (P < 0.001). The participants with CP were more likely to have hypertension, diabetes, high total cholesterol (TC) levels, and high low-density lipoprotein-cholesterol levels and be a current smoker; however, they were less likely to be obese. Multiple logistic regression analysis, adjusted for confounders, indicated that age, male sex, hypertension, diabetes, current smoking, and high LDL-C levels were the independent risk factors for CP. There was a lower risk of CP with alcohol consumption. The findings suggest that managing the conventional risk factors is crucial to reduce the burden of cardiovascular and cerebrovascular diseases in the low-income population in China.

    Full Text Available Cardiovascular diseases (CVDs causes of worldwide preventable morbidity and mortality. CVDs are a leading cause of mortality and morbidity in developing countries, and rates are expected to rise over the next few decades. The prevalence of CVD risk factors is dramatically increasing in low-and middle-income African countries, particularly in urban areas. We carried out a cross-sectional population-based survey in Imezi-Owa, a rural community in South East Nigeria to estimate the prevalence of major cardiovascular risk factors in both men and women aged 40–70 years. A total of 858 individuals made up of 247 (28.8% males and 611 (71.2% females were recruited. The mean age of the subjects was 59.8±9.9 years. The prevalence of the different cardiovascular risk factors among the 858 subjects was as follows: hypertension 398 (46.4% subjects, generalized obesity as determined by BMI 257 (30% subjects, abdominal obesity 266 (31% subjects, dysglycaemia 38 (4.4% subjects and hypercholesterolaemia 32 (3.7% subjects. Prevalence of hypertension and dysglycaemia was higher in men while the others were higher in women. Only hypertension (P=.117 and hypercholesterolaemia (P=.183 did not reveal any significant association with gender. Prevalence of CVD risk factors was highest in subjects aged 65 to 70 years.

    Full Text Available Parasitic infections, which are among the most common infections worldwide, disproportionately affect children; however, little is known about the impact of parasitic disease on growth in very early childhood. Our objective was to document the prevalence of parasitic infections and examine their association with growth during the first three years of life among children in coastal Kenya.Children enrolled in a maternal-child cohort were tested for soil transmitted helminths (STHs: Ascaris, Trichuris, hookworm, Strongyloides, protozoa (malaria, Entamoeba histolytica and Giardia lamblia, filaria, and Schistosoma infection every six months from birth until age three years. Anthropometrics were measured at each visit. We used generalized estimating equation (GEE models to examine the relationship between parasitic infections experienced in the first three years of life and growth outcomes (weight, length and head circumference. Of 545 children, STHs were the most common infection with 106 infections (19% by age three years. Malaria followed in period prevalence with 68 infections (12% by three years of age. Filaria and Schistosoma infection occurred in 26 (4.8% and 16 (2.9% children, respectively. Seven percent were infected with multiple parasites by three years of age. Each infection type (when all STHs were combined was documented by six months of age. Decreases in growth of weight, length and head circumference during the first 36 months of life were associated with hookworm, Ascaris, E. histolytica, malaria and Schistosoma infection. In a subset analysis of 180 children who followed up at every visit through 24 months, infection with any parasite was associated with decelerations in weight, length and head circumference growth velocity. Multiple infections were associated with greater impairment of linear growth.Our results demonstrate an under-recognized burden of parasitism in the first three years of childhood in rural Kenya.

    This study aimed to examine the relationship between the fat-free mass (FFM) and fat mass (FM) and between the fat-free mass index (FFMI) and fat mass index (FMI) in Chinese children using the Hattori chart and to compare the changing pattern with Korean counterparts. In this study, 1541 (764 girls) children and adolescents aged 5-19 yr were recruited from southern China. The subjects' body composition was measured using dual-energy X-ray absorptiometry. The relationship between FFM and FM and between FFMI and FMI were delineated using the Hattori chart. Between 5 and 12 yr, a concurrent increase in FFM and FM and in FFMI and FMI was found in both sexes. After 12 yr, the age-related changing patterns are generally characterized by a sharp increase in FM, with a relatively small increase in FFM for girls, and a sharp increase in FFM, with a relatively little fluctuation in FM for boys. The increase in weight and BMI with age for this stage is largely due to the increase in FFM and FFMI in boys and in both the FFM and FM and FFMI and FMI components in girls. Sex differences in the patterns of body composition were found in Chinese children and adolescents.

    To assess sexual activity, sexual function, and their correlation with vaginal maturation status among middle-aged Chinese women. A cross-sectional study with comparisons across age groups was carried out. In all, 120 women aged 45 to 60 years were recruited into three groups: 45 to 50 (youngest group), 51 to 55 (intermediate group), and 56 to 60 years old (eldest group). Sexual function was assessed through the Female Sexual Function Index (FSFI); vaginal maturation status was determined through the Vaginal Maturation Index (VMI) and pH value. Sexual activity was recorded with self-administered questionnaires. Low sexual frequency was present in a higher proportion of women, but sexual distress was identified within a lower proportion of women in the eldest group. The total FSFI score was significantly lower in the eldest group than in the youngest and intermediate groups (P VMI (P VMI was positively correlated with the total FSFI score, the domain score for sexual desire, and lubrication (r = 0.26, 0.25, 0.34; P < 0.05, 0.05, 0.01), but the opposite associations were demonstrated for pH value (r = -0.47, -0.37, -0.38; P < 0.01, respectively), especially with vaginal pain (r = -0.44, P < 0.01). Among middle-aged Chinese women, sexual desire is lower in 56 to 60-year-old women, compared with those aged 45 to 55 years, whereas vaginal dryness and dyspareunia become more prevalent with age. Importantly, sexual function is associated with vaginal maturation status in women at midlife.

    Full Text Available Objective: Cancer risk increases with age, creating a challenge for the Chinese health system. To inform public health policy and research, we evaluated the cancer burden in elderly Chinese. Methods: Based on the published Chinese Cancer Registry Annual Report or related literature and the China Population and Employment Statistics Yearbooks, we estimated the cancer burden of elderly Chinese, who were representative of the Chinese population. We calculated the cancer incidence, cancer-related mortality, potential years of life lost (PYLL, and disability-adjusted life years (DALYs in 2005–2011 by age, sex, district (rural, urban, and calendar year using national cancer registry, publication, and census data. The relative ratios (RRs were determined between the elderly (≥60 years and young (<60 years. Results: Cancer incidence and related mortality in the elderly were 8.47 and 13.96 times, respectively, those in the young. The PYLL and DALY rates of the elderly were 1.63 and 5.00 times, respectively, those in the young. The PYLL and DALY rates for elderly men and rural districts were higher than for elderly women and urban districts. The RRs for male sex and rural districts were higher than for female sex and urban districts. RRs increased sharply from 2005 to 2011. Conclusions: The cancer burden in elderly Chinese was higher in men and rural districts than in women and urban districts, which creates considerable challenges for the Chinese health care system. Comprehensive measures for cancer prevention and treatment in the elderly are needed.

    Annual rainfall total of Southeastern Nigeria varies widely from year to year and across the seasons. Southeastern Nigeria is marked with two distinctive seasons, namely: the rainy season (occurs March through November) and the dry season (December through February). Highest daily rainfall of this area occurs in the months of July through September. Climate change has brought about either prolonged rainy or dry season in this region. Flash floods are common features in Southeastern Nigeria during the rainy (wet) season, but the unprecedented floods of 2012 represent the worst with 21 million people displaced, 597,476 houses destroyed or damaged, over 363 people killed and an estimated loss of USD 19.6 billion. Hydrological extremes such as these affect men and women differently because of the different roles socio-culturally assigned to them. Women are more vulnerable and sensitive to floods and drought because of their conventional gender responsibilities. This study assesses how women and the elderly of rural communities of Southeastern Nigeria are affected by hydrological extremes, their vulnerability to the effects as well as risk reduction approaches to cope with and/or adapt to the impacts of climate change. In the study area, women are predominantly the providers of food, water and fuel, and climate change has adverse impacts on all three. Women in these rural communities practice subsistence farming during the rainy season. Their farm lands are submerged during flood events destroying their crops and they are helpless during prolonged dry seasons. Inadequacy of hydrological data makes it difficult to predict and forecast hydrological extremes in the region. Several other factors exacerbate vulnerability of women and the aged to the impacts of hydrological extremes, such as rural poverty, limited livelihood options, education, lack of basic services, and socio-cultural norms. The poverty level affects their resilience and recovery from any flood disaster. It

    Full Text Available OBJECTIVE: To assess whether treatment outcomes vary with age for adults receiving antiretroviral therapy (ART in a large rural HIV treatment cohort. DESIGN: Retrospective cohort analysis using data from a public HIV Treatment & Care Programme. METHODS: Adults initiating ART 1(st August 2004-31(st October 2009 were stratified by age at initiation: young adults (16-24 years mid-age adults (25-49 years and older (≥50 years adults. Kaplan-Meier survival analysis was used to estimate mortality rates and age and person-time stratified Cox regression to determine factors associated with mortality. Changes in CD4 cell counts were quantified using a piecewise linear model based on follow-up CD4 cell counts measured at six-monthly time points. RESULTS: 8846 adults were included, 808 (9.1% young adults; 7119 (80.5% mid-age adults and 919 (10.4% older adults, with 997 deaths over 14,778 person-years of follow-up. Adjusting for baseline characteristics, older adults had 32% excess mortality (p = 0.004 compared to those aged 25-49 years. Overall mortality rates (MR per 100 person-years were 6.18 (95% CI 4.90-7.78; 6.55 (95% CI 6.11-7.02 and 8.69 (95% CI 7.34-10.28 for young, mid-age and older adults respectively. In the first year on ART, for older compared to both young and mid-aged adults, MR per 100 person-years were significantly higher; 0-3 months (MR: 27.1 vs 17.17 and 21.36 and 3-12 months (MR: 9.5 vs 4.02 and 6.02 respectively. CD4 count reconstitution was lower, despite better virological response in the older adults. There were no significant differences in MR after 1 year of ART. Baseline markers of advanced disease were independently associated with very early mortality (0-3 months whilst immunological and virological responses were associated with mortality after 12 months. CONCLUSIONS: Early ART initiation and improving clinical care of older adults are required to reduce high early mortality and enhance immunologic recovery, particularly

    Based on the analysis of the problems existing in Chinese basic old - age insurance system under the visual angle of fairness, it is found out there is some unfairness phenomenon between urban and rural areas,among society people, different regions and generations in Chinese basic old - age insurance system. Therefore, it is proposed that China should transfer its concept of system design, establish and perfect the "Social Insurance Law" so as to lay the legal foundation for the design of system and perfect the new rural social old - age insurance system. Meanwhile, a series of countermeasures, such as improving the overall arrangement of old-age insurance, building up unified old -age insurance system, and enriching personal account, are presented in order to solve the unfairness problem of Chinese basic old - age insurance system.%对公平视角下中国基本养老保险制度存在的问题进行了分析之后,发现中国基本养老保险制度存在城乡之间不公平、社会人群之间不公平、地区之间不公平以及代际不公平的现状,由此提出中国目前应转变制度设计理念,建立健全《社会保险法》,为制度奠定法律基础,完善新型农村社会养老保险制度;提高养老保险统筹层次,建立统一的养老保险制度和做实个人账户等一系列对策建议,以解决中国基本养老保险制度的公平性问题。

    Limited information is available on the association of obesity defined by both body mass index (BMI) and waist circumference (WC) with incident hypertension in rural China. A total of 9,174 participants ≥18 years old from rural areas in middle of China, free of hypertension, diabetes, myocardial infarction and stroke, were selected in this cohort study. Questionnaire interview and anthropometric and laboratory measurements were performed at baseline (2007–2008) and follow-up (2013–2014). During the 6 years of follow-up, hypertension developed in 733/3,620 men and 1,051/5,554 women. After controlling for age, education level, smoking, drinking, physical activity, and family history of hypertension, the relative risk of hypertension was lower for participants with high BMI but normal WC than those with both BMI and WC obesity for men 18–39 and 40–59 years old. Women 18–39 years old with normal BMI but high WC showed a 1.96-fold risk of hypertension, and being female with age 40–59 years and high BMI but normal WC was independently associated with hypertension incidence as compared with both normal BMI and WC. BMI is more associated with hypertension as compared with WC in both genders. High WC tends to add additional risk of hypertension in young women. PMID:27545898

    The amounts of litter produced and nutrients returned play a fundamental role in the productivity and biogeochemical and nutrient cycling of forest ecosystems. We monitored annual litterfall production, nutrient return, and monthly dynamics over a one-year period in Chinese fir plantations aged 10, 22, and 34 years. Our objective was to quantify litterfall and nutrient return over a complete harvest rotation of Chinese fir. Annual litterfall production increased with stand age and was recorded as (3,294.6 ± 360.4), (3,733.9 ± 211.2), and (4,876.1 ± 212.8) kg ha-1 a-1 in stands aged 10, 22 and 34 years, respectively. Total litter production was significantly greater in the stand aged 34 years than in the stand aged 10 years (pN (39.32–62.04 kg ha-1 a-1)>K (15.95–22.44 kg ha-1 a-1)>P (1.30–1.63 kg ha-1 a-1). C, N, K and P input to soil was significantly lower in the 10-year-old stand in comparison to the 22-and 34-year-old stands (p<0.05). Litterfall production and nutrient return (C, N and K) followed similar patterns, and C and N input to soil was significantly related to litterfall production (needle, branch and total litterfall). C, N, P and K input to soil and total litterfall production were mainly driven by needle litterfall.

    Full Text Available Introduction: The World Health Organization has a long tradition on the methodology and monitorization of oral health epidemiological investigations, even in the field of dental caries. According to the targets to be attained in 2020, at the age of 6 years, 80% of children should be cavity‐free and, at the age of 12, DMFT should be no more than 1.5. Based on WHO targets for 2020, an epidemio‐ logical study was performed on school children affected by dental caries, aged between 7‐12 years, from the rural areas of the Dolj County. Methodology: The study protocol included conventional and meticulous visual clinical examination of students, according to WHO methodology, in the Pedodontic Clinics of Craiova ‐ Faculty of Medical Dentistry. Also calculated was the DMFT index, by analy‐ sis of the DT, MT, FT components, as well as the dmft index, by analysis of the dt, mt, ft components. Results: The mean indices of carious experience in temporary den‐ tition decrease with age, due to the progressive disappear‐ ance of milk teeth. The DMFT index values are given, in particular, by components that indicate the number of teeth affected by caries and not of the blocked ones. Con‐ clusions: The results obtained emphasize the need for den‐ tal health education programs at national and community level, the kindergartens and schools having a great poten‐ tial to influence dental health care habits in children. Also emphasized was the need for regional prevention pro‐ grams, as part of an overall national program, which has to consider the socio‐economic and cultural factors.

    Full Text Available Abstract Background Vitamin D deficiency is associated with a variety of chronic metabolic diseases. Limited evidence regarding vitamin D deficiency exists within the Chinese population. The present study aims to examine the association between serum vitamin D concentrations and cardiometabolic risk factors in the young and middle-aged, urban Chinese population Methods The cross-sectional relationships between serum 25-hydroxyvitamin D [25(OHD] concentrations and indices of adiposity and cardiometabolic risk factors (e.g., body mass index, waist circumference, fasting plasma glucose, etc. were evaluated in 601 non-diabetic adults. Result Vitamin D deficiency or insufficiency was present in 66% of the tested population, and serum 25(OHD levels were lower in patients who were overweight/obese or suffered metabolic syndrome when compared to individuals of healthy weight without metabolic syndrome (24.08 ± 8.08 vs 31.70 ± 11.77 ng/ml, 21.52 ± 6.9 vs 31.74 ± 10.21 ng/ml respectively. 25(OHD was inversely associated with waist circumference, fasting glucose, fasting insulin, triglycerides and LDL-cholesterol, and it was positively associated with HDL-cholesterol in a multivariable-adjusted regression model. Conclusion Vitamin D deficiency is common in the young and middle-aged, urban Chinese population, with high prevalence in overweight/obese individuals and patients with metabolic syndrome. Low vitamin D concentration was associated with indices of adiposity and cardiometabolic risk factors. Further studies are warranted to elucidate the cause-effect relation between vitamin D status, obesity and related metabolic disorders. Trial registration Current Controlled Trials (ISRCTN21527585

    Full Text Available Background. α-Synuclein (SNCA and microtubule-associated protein tau (MAPT are the two major genes independently, but not jointly, associated with susceptibility for Parkinson’s disease (PD. The SNCA gene has recently been identified as a major modifier of age of PD onset. Whether MAPT gene synergistically influences age of onset of PD is unknown. Objective. To investigate independent and joint effects of MAPT and SNCA on PD onset age. Methods. 412 patients with PD were recruited from the Australian PD Research Network (123 and the Neurology Department, Ruijin Hospital Affiliated to Shanghai Jiaotong University, China (289. MAPT (rs17650901 tagging H1/H2 haplotype and SNCA (Rep1 were genotyped in the Australian cohort, and MAPT (rs242557, rs3744456 and SNCA (rs11931074, rs894278 were genotyped in the Chinese cohort. SPSS regression analysis was used to test genetic effects on age at onset of PD in each cohort. Results. SNCA polymorphisms associated with the onset age of PD in both populations. MAPT polymorphisms did not enhance such association in either entire cohort. Conclusion. This study suggests that, in both ethnic groups, SNCA gene variants influence the age at onset of PD and α-synuclein plays a key role in the disease course of PD.

    Aim. The relationship between alcohol consumption and glycometabolic abnormality is controversial, especially in different ethnic population. In this study, a cross-sectional survey was carried out to examine the relationship between alcohol consumption and glycometabolic abnormality in middle-aged and elderly Chinese men. Methods. Using cluster random sampling, Chinese men aged more than 40 years from Changchun, China, were given standardized questionnaires. In total, 1996 individuals, for whom complete data was available, were recruited into the study. We calculated the incidence of prediabetes and newly diagnosed diabetes by three levels of alcohol consumption: light, moderate, and heavy. Multivariate logistic regression models adjusted for socioeconomic variables and diabetes-related risk factors were used to analyze the association between alcohol consumption and the onset of prediabetes and diabetes. Results. The univariate analysis revealed higher incidence of prediabetes among drinkers (32.8%) compared with nondrinkers (28.6%), particularly in heavy alcohol consumers. The logistic regression analysis showed that alcohol consumption, especially heavy consumption, was an independent risk factor for prediabetes. Conclusions. Alcohol consumption, heavy consumption in particular, is an independent risk factor for the development of prediabetes, but not for diabetes.

    Full Text Available BACKGROUND: The associations between common variants in the fat mass- and obesity-associated (FTO gene and obesity-related traits may be age-dependent and may differ by sex. The present study aimed to assess the association of FTO rs9939609 with body mass index (BMI and the risk of obesity from childhood to adolescence, and to determine the age at which the association becomes evident. METHODS: Totally 757 obese and 2,746 non-obese Chinese children aged 6-18 years were genotyped for FTO rs9939609. Of these, a young sub-cohort (n = 777 aged 6-11 years was reexamined 6 years later. Obesity was defined using the sex- and age-specific BMI cut-offs recommended by the International Obesity Task Force. RESULTS: The associations of FTO rs9939609 with BMI and obesity did not appear until children reached 12-14 years. The variant was associated with an increased BMI in boys (β = 1.50, P = 0.004 and girls (β = 0.97, P = 0.018, respectively. Thereafter, the magnitude of association increased in girls at ages 15-18 years (β = 2.02, P0.05. Age was found to interact with the variant on BMI (P<0.001 and obesity (P = 0.042 only in girls. In the sub-cohort, the associations of FTO rs9939609 with BMI (β = 1.07, P = 0.008 and obesity (OR = 2.09, 95% CI: 1.12, 3.91 were only observed 6 years later (ages 12-18 years in girls, even after adjusting for baseline BMI. CONCLUSIONS: The association between FTO rs9939609 and obesity-related traits may change from childhood to adolescence in Chinese individuals, and the association may start as early as age 12 years, especially in girls.

    Suicidal ideation, plans, and attempts have been found to be predictors of suicide. This study aims to estimate the suicidal behaviors in rural China. We studied 784 respondents as informants of suicide and 1,247 respondents as informants of community living controls, with the NCS-R measures on suicidal behaviors. The lifetime prevalence of ideation, plans, and attempts among the informants of suicide was 18.1, 4.1, and 1.7%, and the 12-month prevalence was 12.1, 2.2, and 0.4%, respectively. The prevalence scores were higher for the family members than for friends of suicide. The risk factors for suicidal behaviors include being parents or spouse of the suicide, female gender, low education level, and being never married. As suicidal behaviors are more observed among those who have a suicide death in the family or among close friends, suicide screening and intervention efforts should be focused on this type of population.

    Single grain zircon U-Pb geochronology has demonstrated great potentials in extracting tectonic and atmospheric circulation signal carried by aeolian, fluvial, and fluviolacustrine sediments. A routine in this sort of studies is analyzing 100-150 grains and then compares zircon U-Pb age spectra between the measured sample and the potential sources. Here we compared the zircon U-Pb age results of the late Miocene-Pliocene Red Clay sequence of two neighboring sites from the Chinese Loess Plateau where similar provenance signal is expected. Although the results from the 5.5 Ma sediment support this prediction, the results from the 3 Ma sediment at these two sites differ from each other significantly. These results emphasize the importance of increasing analysis number per sample and combining the zircon U-Pb geochronology with other provenance tools in order to get reliable provenance information.

    To establish a preliminary thermal and mechanical somatosensory profile using a standardized quantitative sensory testing (QST) to investigate site, gender and age differences in healthy Chinese. Twenty younger (age: 20-40 years, 10 men, 10 women) and twenty older (age: 41-61 years, 10 men, 10 women) healthy participants completed the study. Cold detection threshold (CDT), warm detection threshold (WDT), cold pain threshold (CPT), heat pain threshold (HPT), mechanical detection threshold (MDT) and mechanical pain threshold (MPT) were measured at five sites: Left hand, bilaterally at the mental area, tip of tongue and the lower lip mucosa. Mixed model ANOVAs with repeated measures were used to analyze the data. MDT(p < .001) and MPT (p < .05) were significantly higher on the hand compared to the mental areas. The CDT ( p = .006) was significantly higher and WDT (p < .001) was significantly lower at the tongue compared to lip mucosa and CDT (p < .001) was higher at the tongue mucosa than at the mental areas. WDT (p < .001) and HPT (p < .05) were significantly higher at the tip of the tongue and the lower lip mucosa compared to the mental areas. Significantly lower sensitivity for WDT (p < .001) and CDT (p = .004) were found in the older group compared to the younger group. Significant gender differences were found with less sensitivity for WDT (p = .024) and MDT (p = .003) in men compared to women. Application of standardized QST can provide valuable information of orofacial somatosensory phenotypes in a Chinese population. Age, gender and site are mandatory to control for.

    Full Text Available BACKGROUND: Studies in Western populations find that depression is associated with inflammation and obesity. The present study aimed to evaluate the relation of depressive symptoms with inflammatory factors and adipose-derived adipokines in middle-aged and older Chinese. METHODOLOGY/PRINCIPAL FINDINGS: Data were from 3289 community residents aged 50-70 from Beijing and Shanghai who participated in the Nutrition and Health of Aging Population in China project. Depressive symptoms were defined as a Center for Epidemiological Studies of Depression Scale (CES-D score of 16 or higher. Plasma concentrations of C-reactive protein (CRP, interleukin-6 (IL-6, adiponectin, resistin, plasminogen activator inhibitor-1 (PAI-1 and retinol binding protein 4 (RBP4 were measured. Of the 3289 participants, 312 (9.5% suffered from current depressive symptoms. IL-6 level was higher in participants with depressive symptoms compared to their counterparts in the crude analyses (1.17 vs. 1.05 pg/mL, p = 0.023 and this association lost statistical significance after multiple adjustments (1.13 vs. 1.10 pg/mL, p = 0.520. Depressive symptoms were not associated with increased mean levels of any other inflammatory factors or adipokines in the unadjusted or adjusted analyses. CONCLUSIONS/SIGNIFICANCE: We found no evidence that depressive symptoms were associated with inflammatory factors and adipokines in the middle-aged and older Chinese populations. Prospective studies and studies in clinically diagnosed patients are needed to confirm our results and clarify the relation of depression with inflammatory factors and adipokines.

    Full Text Available Abstract Background Malaria remains to be the major cause of morbidity and mortality among pregnant women and children in Ethiopia. The aim of this study was to investigate the local perceptions, practices and treatment seeking behaviour for malaria among women with children under the age of five years. Methods This community-based study was conducted in 2003 in an area of seasonal malaria transmission in Adami Tulu District, south-central Ethiopia. Total samples of 2087 rural women with children less than five years of age from 18 rural kebeles (the smallest administrative units were interviewed about their perceptions and practices regarding malaria. In addition, focus group discussions and in-depth interviews were conducted on similar issues to complement the quantitative data. Results Malaria, locally known as busaa, is perceived as the main health problem in the study area. Mosquitoes are perceived to be the main cause of the disease, and other misperceptions were also widespread. The use of prevention measures was very low. Most mothers were familiar with the main signs and symptoms of mild malaria, and some of them indicated high grade fever, convulsions and mental confusion as a manifestation of severe malaria. Very few households (5.6% possessed one or two nets. More than 60% of the mothers with recent episodes of malaria received initial treatment from non-public health facilities such as community health workers (CHWs (40% and private care providers (21%. Less than 40% of the reported malaria cases among women were treated by public health facilities. Conclusion Malaria was perceived as the main health problem among women and children. The use of malaria preventive measures was low. A significant proportion of the respondents received initial malaria treatments from CHWs, private care providers and public health facilities. Concerted effort is needed to scale-up the distribution of insecticide-treated nets and improve the knowledge of

    Objective: To investigate the relationship between frequencies of prenatal care and neonatal low birth weight (LBW) among women of childbearing age from the rural areas of Shaanxi province. Methods: A questionnaire survey was conducted among the childbearing-aged women from the rural areas. Samples were selected through multi stage stratified random sampling method. The childbearing aged women were in pregnancy or having had definite outcomes of pregnancy. Measurement of data was described by median±standard deviation, and chi square test was used to compare the rates. Neonatal low birth weight and frequencies of prenatal care were dependent variables and independent variables grouped into the generalized Poisson regression model. Confounding factors were under control. Results: The overall incidence rate of LBW was 3.75% among 18 911 rural women of childbearing age during 2010-2013. Frequencies on pregnancy care were up to 15 times (0.70%), with a minimum of 0 (0.70%), an average of 5.65±2.74 times (including ≥10 times accounted for 12.37%; ≥7 times accounted for 28.52%; ≥5 times accounted for 62.80% and controlling confounding factors, results from the generalized Poisson regression analysis revealed that the difference was statistically significant when compared to the reference group. The incidence of neonatal LBW in the 7 group (OR=1.61, 95%CI:1.31-2.00) while in the prenatal care, among women of childbearing age.

    Conclusions: Our findings suggest that nocturnal enuresis is a common problem among school children especially with low income, lower age, family history of enuresis and history of urinary tract infection. Enuresis is a pediatric public health problem and efforts at all levels should be made such as preventive, etiological and curative. The ratio of males to females in this study was 1.86 that is comparable to other data of the same study. [Int J Res Med Sci 2014; 2(1.000: 202-205

    Physique has been useful in assessing the outcome of underlying growth and maturity processes, which leads to a better understanding of variation in child and adult health. However, a high endomorphy rating has been associated with hypertension in adults, posing a serious threat to their health status, while receiving little attention in children. The study examined the association between somatotypes, body mass index (BMI) and blood pressure (BP) in 6-13-year-old rural children, in Ellisras, South Africa. A total of 1902 subjects (980 boys and 922 girls) aged 6-13 years were studied as part of the Ellisras Longitudinal Study. Height, weight, four skinfold sites, two breadths, and two girths were measured according to the International Society for the Advancement of Kinanthropometry (ISAK). The Heath-Carter method of somatotyping was used, together with internationally recommended cut-off points for BMI in children. Hypertension, defined as the average of three separate BP readings, where the systolic or diastolic BP is greater than or equal to the 95th percentile for age and sex, was determined. The prevalence of hypertension ranges from 1 to 5.8% in boys and 3.4-11.4% in girls. The prevalence of overweight ranges from 1.1 to 2.9% in boys and 0.6-4.6% in girls. Systolic BP and BMI showed a significant positive correlation at age 6 years (r = 0.436) and 10-13 years (r = 0.180-0.246 in boys and r = 0.221-0.271 in girls). Diastolic BP showed an insignificant correlation with the BMI and somatotype components in boys and girls. A significant association exists between BP and BMI, and ectomorphy components even after being adjusted for age, gender and height. The need to manage hypertensive individuals is evident in this sample to combat this chronic disease from an early age. Follow-up studies should investigate the relationship between BP and the dietary intake of these children.

    Full Text Available Purpose. The etiology of neovascular age-related macular degeneration (nAMD cannot be completely explained by identified environmental risk factors or single-locus gene variants. This study was to explore the potential interactions among gene variants on nAMD in Chinese population. Methods. 43 SNPs located in different genes were genotyped in 932 Chinese individuals (464 nAMD patients and 468 controls. We explored the potential interactions among gene variants using generalized multifactor dimensionality reduction (GMDR algorithm and the method to measure the departure from the additivity model. Results. The joint effect that involved CFH rs1061170 and HTRA1 rs3793917 was shown statistically significant (P < 0.001 with the highest cross-validation consistency (10/10 and the best testing balanced accuracy (64.50%. In addition, based on the method to measure the departure from the additivity model, the synergy index (S was 2.63 (1.09–6.38 and the attributable proportion due to interaction (AP was 55.7% (21.4%–89.9%, which suggested that a common pathway may exist for these genes for nAMD. Those who carried CC for rs3793917 and TC/CC for rs1061170 were at the highest risk of nAMD (OR: 9.76, 95% CI: 4.65–20.51. Conclusions. Evidence that the joint effect that involved CFH and ARMS2/HTRA1 may contribute to the risk of neovascular AMD in Chinese population was obtained.

    Sporotrichosis is commonly a chronic infection caused by Sporothrix schenckii, a saprophytic fungus and is usually limited to cutaneous and subcutaneous tissues. Disseminated systemic, osteoarticular or pulmonary sporotrichosis have been reported but nasal sinusitis by this fungus is extremely infrequent. Earlier report from southern India documented a case of maxillary sinusitis by Sporothrix schenckii. Here we report a similar case of bilateral maxillary sinusitis in a middle aged female from a village of Bihar, a state in eastern India. She underwent endoscopic maxillary sinus surgery for nasal symptoms and diagnosed to have sporotrichotic infection of maxillary sinuses. The diagnosis was done by mycological and histopathological examination and patient improved under antifungal chemotherapy. PMID:27134873

    The current study analyzed the 1999 and 2001 waves of the Nihon University Japanese Longitudinal Study of Aging. Two measures of social integration were associated with lower risks of being physically disabled or depressed at Wave 1 and with a lower risk of progressing into deeper levels of physical disability and depression by Wave 2. Ceteris paribus, compared to elderly urbanites, elderly ruralites had a much higher risk of being physically disabled but much lower odds of being depressed. And compared to elderly men, elderly women had similar risks of being physically disabled but much higher odds of being depressed. Suggestions are made on how future research on longevity in Japan, the world's most longevous nation, can explore the links among social integration, place, gender, and the postponement of mortality.

    Associations between diet, physical activity, parenting, and acculturation among Chinese-American children are understudied. Parents/caregivers of children attending child-care programs in Boston Chinatown completed a self-administered survey on demographics, child's diet, physical activities, anthropometrics, and parenting practices. Associations were evaluated in multivariable regression analysis, stratified by survey language preference, a proxy for acculturation. Responding Asian families = 132; 86.4% were immigrants; 75.8% completed the Chinese-version survey. Children (mean ± SD: 4.9 ± 1.1 years) did not eat vegetables (31.8%), or play actively outside (45.4%) daily, 64.8% watched television/screens daily; 32.6% were overweight/obese (based on parent report). Parenting practices associated with obesity were apparent. Although healthy-living behavioral outcomes were less prevalent among less acculturated parents; multivariable adjustment attenuated the observed significant differences. Findings suggest opportunities for improvement in study children's diet and healthy-living behaviors, and underscore the need for further research on acculturation, and parenting styles in this population.

    Full Text Available Focusing on three influential contemporary Chinese political fantasy novels, this article contextualizes the stories in the complex spectrum of contemporary Chinese political thoughts and interprets them in light of the rivaling tendencies among the Chinese intellectuals since the 1990s, regarding the issues of rising nationalism and political authoritarianism, the possibilities of fascism and federalism, the role of a strong, centralized state, and the relevance of liberal democracy in China. The article calls attention to fiction as an expression of political thought and concerns, and argues that these novels present a pessimistic and chilling view of China’s political future, in contrast with the optimistic tone of novels of the same genre in the early 20th century, and also challenge an earlier cult of the Western model of liberal democracy.  An earlier Chinese-language version of the paper appeared in the website “Democratic ChinaC”, http://www.minzhuzhongguo.org 12/8/2010, entitled “Zhengzhi huanxiang xiaoshuo zhong de dangdai Zhongguo sixiang: jiedu Huang Huo, Zhongnanhai zuihou de douzheng, he Shengshi, Zhongguo 2013” [Chinese Political Thought as Reflected in Political Fantasy Novels: Interpreting 'Yellow'' Peril', 'The End of Red Chinese Dynasty', and 'A Flourishing Age: China, 2013'

    Full Text Available Background: India is experiencing lowest child sex ratio of the world. The deficit of girl children has been progressively increasing, in spite of so many laws to favour them like Sharda act, act against dowry and law against female feticide, i.e. PC & PNDT. The present study attempted to explore the determinants of negative preference of female fetuses at rural setup and preferences for prevention of female foeticide. Methods: In a prospective, multicentric, cohort study, 2203 married women of reproductive age group were interviewed by pretested piloted structured questionnaire. SPSS software was used for statistical analysis. Results: Common causes for not preferring daughters were related to their marriages expenses, dowry along with exogamy and practices regarding death ceremonies of parents. Self deprived image of today’s woman by herself is mainly responsible for not allowing her to welcome another girl child in a family. Conclusions: Female foeticide is still in practice inspite of awareness programmes and existing law. Main reason for it is societal need due to marriage related customs and cultures along with unethical practices by service providers. To increase in self-esteem of women can only reduce the volume of service receiver along with upliftment of moral and ethical values of service providers from the beginning of their medical training can prevent it to happen.

    Purpose To establish and propose a national body mass index (BMI) reference for screening overweight and obesity in Chinese school-age children and adolescents. Methods 2000 CNSSCH (Chinese National Survey on Students Constitution and Health) data, including 216 620 primary and secondary school students aged 7 to 18 years old, were used as a reference population. Compared with those of the NCHS internatioanl reference, three temporary sets of cut-off BMI were proposed by testing different combinations of P8s, P9o, and P95. When physiological and biochemical measures between and among "obesity","overweight", and "normal weight" groups were taken into consideration, set Ⅱ was selected to be the most appropriate one.The sex-age-specific curves were then plotted and smoothed by using B-spline method. Results Based on the samples from costal developed metropolis, the BMI curves successfully overcame the shortcomings of lower and level-off tendency of the Chinese total population. Temporary set Ⅱ, composed by cut-offs of P85 for overweight and P95 for obesity, was finally selected by its sensitivity and peculiarity. BMI 24 and 28 were used as cut-offs for overweight and obesity for both males and females aged 18 years old. These cut-offs, consistent with Chinese Adult's Reference, was proposed as the Body mass index reference for screening overweight and obesity in Chinese school-age children and adolescents. Conclusion The new reference clearly showed its superiorty in both prospectivity and actuality. The proposed reference minimized the gaps of the BMI curve between Chinese adolescents and the international reference. Most importantly was that it was consistent with the Eastern Asia ethnic characteristics of body fatness growth. It was therefore proposed by the Working Group on Obesity in China (WGOC) to use it as an nationwide reference for screening overweight and obesity of school-age children and adolescents in China.

    In 173 urban residents and 232 rural dairy-farm residents (age range, 0-70 years) who were stratified for age, the frequency of antiverocytotoxin 2 antibodies (VT2 Abs) (frequency in urban residents, 46%; frequency in rural residents, 65%) was significantly higher than that of antiverocytotoxin 1 antibodies (VT1 Abs) (frequency in urban residents, 12%; frequency in rural residents, 39%) (P< or =.001). The frequency of VT2 Abs (93%) was also significantly higher than that of VT1 Abs (50%) in 14 patients with hemolytic uremic syndrome (HUS) associated with verocytotoxin-producing Escherichia coli (VTEC) strains that expressed both toxins. In urban residents, the frequency of both antibodies tended to decrease between the first and the second decades of life, and it then increased until the fifth decade of life, before, in the case of VT2 Abs, decreasing again. This pattern, which inversely reflects the age-related incidence of HUS, is consistent with a role for antiverocytotoxin antibodies in protective immunity. In dairy-farm residents, peak frequencies of antibodies to both toxins occurred during the first decade of life and remained elevated for 3 decades before decreasing, a pattern consistent with frequent exposure to bovine VTEC from an early age.

    The genetic influences on aging-related phenotypes, including cognition and depression, have been well confirmed in the Western populations. We performed the first twin-based analysis on cognitive performance, memory and depression status in middle-aged and elderly Chinese twins, representing the world's largest and most rapidly aging population. The sample consisted of 384 twin pairs with a median age of 50 years. Cognitive function was measured using the Montreal Cognitive Assessment (MoCA) scale; memory was assessed using the revised Wechsler Adult Intelligence scale; depression symptomatology was evaluated by the self-reported 30-item Geriatric Depression (GDS-30)scale. Both univariate and multivariate twin models were fitted to the three phenotypes with full and nested models and compared to select the best fitting models. Univariate analysis showed moderate-to-high genetic influences with heritability 0.44 for cognition and 0.56 for memory. Multivariate analysis by the reduced Cholesky model estimated significant genetic (rG = 0.69) and unique environmental (rE = 0.25) correlation between cognitive ability and memory. The model also estimated weak but significant inverse genetic correlation for depression with cognition (-0.31) and memory (-0.28). No significant unique environmental correlation was found for depression with other two phenotypes. In conclusion, there can be a common genetic architecture for cognitive ability and memory that weakly correlates with depression symptomatology, but in the opposite direction.

    To explore the value of estimating chronologic age based on the grades of mandibular third molar development. To evaluate whether mandibular third molar could be used as an indicator for estimating the age under or over 18 years. The mineralization status of mandibular third molar of 1 845 individuals aged 10 - 30 was graded and marked based on Demirjian's classification of grades reformed by Orhan. Gender difference was examined by t-test. A cubic regression model was established to analyze the correlation between third molar and chronologic age. Each grade of age cumulative distribution diagram and ROC curve was respectively performed to evaluate the relationship between third molar and the age of 18. Using Bayes discriminant analysis, an equation was established for estimating the age of 18. The inner-rater reliability was 0.903. Statistical analysis showed a moderate correlation between age and grade. Significant differences of both genders were found only in grade D and H (P Third molar development shows a high correlation with age, and combined with other indicators, it can be used to estimate the age of 18.

    Physical activity may modify the association of adiposity with type 2 diabetes. We investigated the independent and joint association of adiposity and physical activity with fasting plasma glucose, impaired fasting glucose, and type 2 diabetes in a Chinese population. Middle-aged and older Chinese (n=28,946, ≥50 years, 72.4%women) from the Guangzhou Biobank Cohort Study were examined in 2003-2008. Multivariable regression was used in a cross-sectional analysis. BMI, waist circumference, and waist-to-hip ratio (WHR) were positively associated with type 2 diabetes after multiple adjustment, most strongly for WHR with odds ratio (OR) of 3.99 (95% CI 3.60-4.42) for highest compared with lowest tertile. Lack of moderate-to-vigorous physical activity, but not walking, was associated with diabetes with an OR of 1.29 (1.17-1.41). The association of moderate-to-vigorous activity with fasting glucose varied with WHR tertiles (P=0.01 for interaction). Within the high WHR tertile, participants who had a lack of moderate-to-vigorous activity had an OR of 3.87 (3.22-4.65) for diabetes, whereas those who were active had an OR of 2.94 (2.41-3.59). In this population, WHR was a better measure of adiposity-related diabetes risk than BMI or waist circumference. Higher moderate-to-vigorous activity was associated with lower diabetes risk, especially in abdominally obese individuals.

    Full Text Available Cytochrome P450 2C9 (CYP2C9 metabolizes dehydroepiandrosterone-sulfate (DHEA-S, but in elderly people the amount of DHEA-S remaining after CYP2C9 metabolization may be insufficient for optimal health. A prediction model, molecular docking, and molecular dynamics were used to screen the Traditional Chinese Medicine (TCM database to determine molecular compounds that may inhibit CYP2C9. The candidate compounds apocynoside(I, 4-methoxymagndialdehyde, and prunasin have higher Dock Scores, and prediction bioactivity than warfarin (the control drug. The interaction between 4-methoxymagndialdehyde and CYP2C9 is more intense than with other TCM compounds, but the simulation is longer. In these compounds, apocynoside(I and prunasin have a greater number of pathways for their flexible structure, but these structures create weak interactions. These candidate compounds, which are known to have antioxidation and hypolipidemic functions that have an indirect effect on the aging process, can be extracted from traditional Chinese medicines. Thus, these candidate compounds may become CYP2C9 inhibitors and play an important role in providing optimal health in the elderly.

    Although serum uric acid (sUA) is not a criterion for diagnosing metabolic syndrome (MetS), many studies have identified a positive association between sUA and MetS in patients of various ages and ethnicities. This association has not been fully established in the very elderly. Cross-sectional and longitudinal study. A total of 18,906 Chinese elderly aged 65 and older undergoing routine health checkups in Taiwan were enrolled. Modified Adult Treatment Panel III criteria were used to define MetS. All participants were further divided into nine groups with gender specification according to age (the young-old, 65 to 74; old-old, 75 to 84; and oldest-old, 85 and over) and sUA concentration tertile (males: sUAG1, 6.7 mg/dL; females: sUAG1, 5.9 mg/dL). A cross-sectional study was first performed to determine the correlation between sUA and MetS and its components. A longitudinal study then excluded subjects with MetS at baseline to explore the risk of MetS according to sUA levels in 3 age groups. In the cross-sectional study, we observed a graded, positive association between sUA and MetS components that diminished after age 75. Subjects with higher sUA levels had higher odds ratios (OR) for the occurrence of MetS in the young-old and old-old groups of both sexes (PChinese elderly were associated with a higher risk of developing MetS. sUA levels are thus regarded as a potential tool for early diagnosis of MetS. However, this association diminished in those over 75 years of age.

    Full Text Available To evaluate the associations between candidate FTO single nucleotide polymorphisms (SNPs and obesity, a case-control study was conducted among Chinese school-age children, which included 500 obese cases and 500 matched controls (age, gender and location. We selected 24 candidate FTO tag-SNPs via bio-informatics analysis and performed genotyping using SNPScan technology. Results indicated that rs7206790 and rs11644943 were significantly associated with obesity among school-age children in both additive and recessive models (P<0.05 after adjusting confounders. Comparing rs7206790 CC and CG genotype of carriers, those carrying the GG genotype had an increased risk of obesity (adjusted odds ratio [OR], 3.76; 95% Confidence interval [CI], 1.24-11.43. Carriers of the AA allele of rs11644943 had a lower risk of obesity (adjusted OR, 0.16; 95% CI, 0.04-0.72 compared with those of the T allele (TT and TA. These two SNPs (rs7206790 and rs11644943 were not Linkage Disequilibrium (LD with previous reported obesity-associated SNPs.

    Full Text Available Abstract Background Although the number of studies on anti-smoking interventions has increased, studies focused on identifying social contextual factors in rural areas are scarce. The purpose of this study was to explore the role of social support and social networks in smoking behavior among middle and older aged people living in rural areas of South Korea. Methods The study employed a cross-sectional design. Participants included 1,057 adults, with a mean age of 60.7 years, residing in rural areas. Information on participants' tobacco use, stress, social support, and social networks was collected using structured questionnaires. The chi-square test, the t-test, ANOVA, and logistic regression were used for data analysis. Results The overall smoking prevalence in the study was 17.4% (men, 38.8%; women, 5.1%. Overall, stress was high among women, and social support was high among men. Smokers had high levels of social support (t = -2.90, p = .0038 and social networks (t = -2.22, p = .0271, as compared to non- and former smokers. Those in the high social support group were likely to be smokers (AOR = 2.21, 95% CI 1.15-4.26. Women with moderate social ties were less likely to smoke (AOR = 0.18, 95% CI 0.05-0.61. Conclusion There was a protective role of a moderate social network level among women, and a high level of social support was associated with smoking behaviors in rural areas. Findings suggest the need for a comprehensive understanding of the functions and characteristics of social contextual factors including social support and social networks in order to conduct more effective anti-smoking interventions in rural areas.

    Vitamin D is known for maintaining Ca homeostasis and bone structure, and may also decrease susceptibility to chronic and infectious diseases. However, data on vitamin D status and its predictors among Southeast Asian populations are limited. We evaluated the distribution and determinants (genetic and environmental) of serum 25-hydroxyvitamin D (25(OH)D) concentrations among 504 middle-aged and elderly participants (aged 45-74 years) in the Singapore Chinese Health Study. Data on dietary and other lifestyle factors were collected by trained interviewers. Serum 25(OH)D concentrations and genetic polymorphisms in vitamin D metabolism pathway enzymes (cytochrome P450 (CYP) 2R1, 3A4, 27B1, 24A1; vitamin D binding protein (also known as group-specific component, GC); and vitamin D receptor) were measured using stored biospecimens. Mean 25(OH)D concentration was 68·8 nmol/l. Serum 25(OH)D concentrations were positively associated with dietary vitamin D intake, and inversely associated with hours spent sitting at work. BMI was not associated with 25(OH)D concentrations. CYP2R1 rs10741657, rs12794714, rs1993116; CYP3A4 rs2242480; and GC rs4588, rs7041, rs16847015, rs2298849 were statistically significantly associated with 25(OH)D concentrations. Individuals with the Gc2-2 haplotype (rs4588AA/rs7041TT) had statistically significantly lower 25(OH)D concentrations compared to all other Gc haplotypes (P-trend Institute of Medicine (US) recommendation for bone health, and 32 % had concentrations of ≥ 75 nmol/l that are thought to be required for broader health effects. Dietary vitamin D intake, hours spent indoors at work and genetic variation in CYP2R1, CYP3A4 and GC are significant predictors of 25(OH)D concentrations among Singapore Chinese.

    Full Text Available BACKGROUND: Association between vitamin D insufficiency and hyperuricemia has not been reported so far. We aimed to study the association of vitamin D insufficiency with elevated serum uric acid among middle-aged and elderly Chinese Han women. METHODS: We collected data from participants residing in Jinchang district of Suzhou from January to May, 2010. Serum uric acid, 25-hydroxy vitamin D and other traditional biomarkers including fasting plasma glucose and blood lipids were determined in 1726 women aged above 30 years. Association between vitamin D insufficiency and elevated uric acid was analyzed in premenopausal and postmenopausal women, respectively. RESULTS: Among postmenopausal women, 25-hydroxy vitamin D level of participants with elevated uric acid was lower than that of those with normal uric acid (median [interquartile range]: 35[28-57] vs 40[32-58], µg/L; P = 0.006. Elevated uric acid was more prevalent in participants with vitamin D insufficiency compared to those without vitamin D insufficiency (16.50% vs 8.08%; P<0.001. Association between vitamin D insufficiency and elevated uric acid was not significant among premenopausal women. However, participants with vitamin D insufficiency were more likely to have elevated uric acid compared with those without vitamin D insufficiency among postmenopausal women (OR, 95% CI: 2.38, 1.47-3.87. Moreover, after excluding individuals with diabetes and/or hypertension, the association of vitamin D insufficiency with elevated uric acid was still significant (OR, 95% CI: 2.48, 1.17-5.44. CONCLUSIONS: Vitamin D insufficiency was significantly associated with elevated uric acid among postmenopausal Chinese Han women. This study suggested that a clinical trial should be conducted to confirm the association of vitamin D insufficiency with hyperuricemia.

    The aim of this study was to identify disease-associated loci in oldest old Han Chinese with atrophic age-related macular degeneration (AMD). This genome-wide association study (GWAS) only included oldest old (≥95 years old) subjects in Rugao County, China. Thirty atrophic AMD patients and 47 age-matched non-AMD controls were enrolled. The study subjects underwent a complete ophthalmic examination. Genomic DNA was extracted from peripheral blood samples. Single nucleotide polymorphisms (SNPs) were scanned by Genome-Wide Human Mapping SNP 6.0 Arrays and GeneChip Scanner 3000 7G. The results were read and analyzed by the Affymetrix Genotyping Console software. We filtered out the SNPs with a no-call rate ≥10%, MAF P old Han Chinese population. This finding may lead to new strategies for screening of atrophic AMD for Han Chinese.

    Background: Few studies have examined the impact of local animal-source foods (ASFs) on the nutritional status of reproductive-age women in developing countries.Objective: We hypothesized that a midmorning snack of local ASF for 6 mo would reduce dietary micronutrient deficiencies [usual intake less than the estimated average requirement (EAR)] and improve blood biomarkers of iron, zinc, and vitamins A and B-12 status among nonpregnant, reproductive-age women in rural Vietnam.Methods: One hundred seventeen women, 18-30 y old, were randomly assigned to receive either an ASF (mean: 144 kcal, 8.9 mg Fe, 2.7 mg Zn, 1050 μg retinoic acid equivalent vitamin A, and 5.5 μg vitamin B-12) or a control snack (mean: 150 kcal, 2.0 mg Fe, 0.9 mg Zn, 0 μg retinoic acid equivalent vitamin A, and 0 μg vitamin B-12) 5 d/wk for 6 mo. Usual nutrient intakes were estimated by repeated 24-h dietary recalls. Blood samples were collected at baseline and 3 and 6 mo. Because of the relation between nutritional status and inflammation, serum C-reactive protein, α-1-acid-glycoprotein, and urinary tract infections (UTIs) were also monitored.Results: Eighty-nine women (47 in the ASF group and 42 controls) completed the study. In the ASF group, intakes of iron and vitamins A and B-12 below the EAR were eliminated, and the prevalence of a low zinc intake was reduced to 9.6% compared with 64.7% in controls (P vitamin B-12 concentrations did not differ. UTI relative risk was 3.9 (P < 0.05) among women assigned to the ASF group who had a low whole-body iron status at baseline.Conclusions: Adding a small amount of locally produced ASF to the diets of reproductive-age Vietnamese women improved micronutrient intakes and iron status. However, the increased UTI incidence in women in the ASF group with initially lower iron stores warrants further investigation. © 2017 American Society for Nutrition.

    Benign prostatic hyperplasia (BPH) is one of the most common medical conditions in middle aged and older men.This study investigated the relationship between serum levels of sex hormones and measures of BPH in the aging male population of China.Prostate symptoms were assessed as part of a free health screening program for men ≥40 years of age.The examination included digital rectal examination,determination of serum prostate-specific antigen levels,International Prostate Symptom Scorn (IPSS) and transrectal ultrasonography.Serum levels of total testosterone (TT),sex hormone binding globulin (SHBG),free testosterone (FT),luteinizing hormone (LH),follicle-stimulating hormone (FSH),prolactin (PRL) and estradiol (E2) were evaluated.The men also completed a health and demographics questionnaire and received a detailed physical examination.The final study population consisted of 949 men with a mean age of 58.9 years.Pearson correlation analysis indicated that there were significant correlations between age and levels of all sex hormones except TT,and between age and prostate volume (PV; r=-0.243; P<0.01) or IPSS (r=0.263; P<0.01 ).Additional significant correlations were found between IPSS and serum levels of LH (r=0.112; P<0.01 ) and FSH (r=0.074; P<0.05),but there were no significant correlations between sex hormone levels and PV.Multivariate linear regression analysis showed significant correlations between age and body mass index (BMI) with PV (P<0.0001).In addition,there was a significant correlation between age and PV with IPSS (P<0.0001).Serum sex hormone levels did not correlate with PV or IPSS.The effects of endocrine changes on measures of BPH in aging men require further investigation in longitudinal and multicenter studies that include patients with all severities of BPH.

    Increasing evidence suggests that gut microbiota underpin the development of health and longevity. However, our understanding of what influences the composition of this community of the longevous has not been adequately described. Therefore, illumina sequencing analysis was performed on the gut microbiota of centenarians (aged 100-108 years; RC) and younger elderlies (aged 85-99 years; RE) living in Bama County, Guangxi, China and the elderlies (aged 80-92 years; CE) living in Nanning City, Guangxi, China. In addition, their diet was monitored using a semiquantitative dietary questionary (FFQ 23). The results revealed the abundance of Roseburia and Escherichia was significantly greater, whereas that of Lactobacillus, Faecalibacterium, Parabacteroides, Butyricimonas, Coprococcus, Megamonas, Mitsuokella, Sutterella, and Akkermansia was significantly less in centenarians at the genus level. Both clustering analysis and UniFraq distance analysis showed structural segregation with age and diet among the three populations. Using partial least square discriminate analysis and redundancy analysis, we identified 33 and 34 operational taxonomic units (OTUs) as key OTUs that were significantly associated with age and diet, respectively. Age-related OTUs were characterized as Ruminococcaceae, Clostridiaceae, and Lachnospiraceae, and the former two were increased in the centenarians; diet-related OTUs were classified as Bacteroidales, Lachnospiraceae, and Ruminococcaceae. The former two were deceased, whereas the later one was increased, in the high-fiber diet. The age and high-fiber diet were concomitant with changes in the gut microbiota of centenarians, suggesting that age and high-fiber diet can establish a new structurally balanced architecture of gut microbiota that may benefit the health of centenarians.

    The prevalence of childhood overweight and obesity has been shown to differ among regions, including rural-urban regional differences within nations. This study obtained simultaneous accelerometry-derived physical activity, 24 h activity, and food records to clarify the potential contributing factors to rural-urban differences in childhood overweight and obesity in Japan. Sixth-grade children (n = 227, 11-12 years old) from two urban elementary schools in Kyoto and four rural elementary schools in Tohoku participated in the study. The children were instructed to wear a pedometer that included a uniaxial accelerometer and, assisted by their parents, keep minute-by-minute 24 h activity and food records. For 12 children, the total energy expenditure was measured by the doubly labeled water method that was used to correct the Lifecorder-predicted activity energy expenditure and physical activity level. The overweight and obesity prevalence was significantly higher in rural than in urban children. The number of steps per day, activity energy expenditure, physical activity level, and duration of walking to school were significantly lower in rural than in urban children. In contrast, the reported energy intake did not differ significantly between the regions. The physical activity and duration of the walk to school were significantly correlated with body mass index. Rural children had a higher prevalence of overweight and obesity, and this may be at least partly caused by lower physical activity, especially less time spent walking to school, than urban children.

    Phthalates are suspected endocrine disrupting chemicals that impair male reproductive function in animal and epidemiological studies. We investigated associations between urinary phthalate metabolites and acrosin activity, along with that between insulin like-factor 3 (INSL3), a Leydig cell function marker, in Chinese adult men and assessed the association between the metabolites and male reproductive function. Serum levels of INSL3 and other hormones, semen parameters, and urinary concentrations of 14 phthalate metabolites in 1066 men were measured. The unadjusted concentrations of phthalates were included as independent variables and urinary creatinine as a separate covariate. INSL3 was negatively associated with mono-2-ethylhexyl phthalate (MEHP) and %MEHP [percentage of MEHP to all di(2-ethylhexyl) phthalate (DEHP) metabolites]. Acrosin activity was negatively associated with mono-n-butyl phthalate (MBP), mono-isobutyl phthalate (MiBP), MEHP and %MEHP. MBP and MiBP were also negatively associated with total testosterone (T), free androgen index (FAI), free testosterone (FT), luteinizing hormone (LH) and sperm morphology and positively associated with DNA fragmentation index (DFI). A negative association between %MEHP and sperm motility was observed. Several other metabolites were also associated with reproductive function. This is the first report on the inverse associations of phthalate metabolites with acrosin activity and INSL3. Phthalates may cause multiple adverse results on reproductive function at environmental levels.

    The use of the magnetic compass in China is documented at least since the Han dynasty (206 BC-220 AD), but may be older. Geomancy (fengshui) practicised for a long time had a profound influence on the face of China's landscape and city plans. The tombs (pyramids) near Xian (together with suburban fields and roads) have strange space orientations, sometimes in the basic south-north direction (with respect to the geographic pole), but ussually with deviations of several degrees to east or west. The use of the compass means that the needle is directed to the actual magnetic pole at the time of construction or last reconstruction of the given tomb. The magnetic pole however, relative to the 'fixed' geographic pole, wanders significantly in time. We successfully correlated (found a close trends), by using paleomagnetic data (for the central China and the time interval of interest), the starting date of pyramids building with respect to the magnetic pole position at that time. As in Mesoamerica, where according to Fuson hypothesis, the Olmecs and Maya oriented their ceremonial buildings and pyramids by compass even before the Chinese, here in central China the same technique may have been used. The agreeement of building alignments with likely magnetic pole positions at the time is fairly good. There are several written records that the knowledge of the various ancient types of compass in China is older than from the Han period but paleomagnetic declinations for China are generally so far not too precise.

    ObjectiveTo study the nutrition habits among Chinese-Korean children and adolescents in Yanbian Autonomous Prefecture, Jilin, China. MethodsData were obtained from the Chinese National Survey on Students’ Constitution and Health in 1995, 2000, 2005, and 2010 for Chinese-Korean children and adolescents aged 7-18 years.The number of the subjects included was 4789, 4704, 5875, and 5315, respectively. ResultsThe rate of the occurrence of stunting showed a declining trend from 1995 to 2010 (for boys:urban, 6.3%; rural, 12.7% in 1995 and 3.5% for both in 2010. For girls: urban, 7.8%; rural, 13.4% in 1995 and 4.2% and 5.5%, respectively, in 2010). Although the ratio of wasting did not show significant differences between the urban and rural children and adolescents in 1995, 2000, 2005, and 2010 respectively, the ratio of occurrence of overweight or obesity increased (for boys: urban, 7.3% and 1.3%in 1995, 17.6% and 12.9% in 2010; rural, 7.0% and 1.3% in 1995, 14.6% and 12.8% in 2010, respectively. For girls: urban, 8.1% and 1.0% in 1995, 17.3% and 8.6% in 2010; rural 5.7% and 0.7% in 1995, 16.4%and 7.4% in 2010, respectively). ConclusionThe ratio of malnutrition in children and adolescents in Chinese-Korean areas declined from 1995 to 2010, and the distinction in malnutrition between the urban and rural areas was negligible in 2010. Further, the ratio of overweight and obesity increased over this period.

    Full Text Available A configuração populacional vem sofrendo acentuadas transformações ao longo da última década. Atualmente, a masculinização e o envelhecimento populacional são apontados como características dessa realidade. Neste sentido, este trabalho teve como objetivo analisar a ocorrência e o comportamento dos processos de masculinização e envelhecimento da população rural de 27 municípios da Região Central do Rio Grande do Sul, em diferentes faixas etárias. Para alcançar esse propósito, utilizaram-se dados da Contagem Populacional de 1996 e 2007 do IBGE referentes à população rural regional sistematizados em quatro faixas: 0 a 14 anos, 15 a 24, 25 a 59 e 60 ou mais anos. As diferenças entre os sexos foram submetidas ao Teste para Diferença entre Duas Proporções com 5% de probabilidade de erro. Também foram calculadas a diferença percentual da população total e de cada sexo entre 1996 e 2007. O processo de masculinização rural consolida sua presença na Região Central do RS, sendo a população adulta atingida com mais intensidade. A sobreposição masculina significativa pode ser observada em todos os municípios, aumentando da primeira a terceira faixa etária. Em alguns municípios, houve uma intensificação da masculinização rural também entre a população idosa. Também pode ser observado, de forma geral, um abrandamento do predomínio masculino entre a população jovem. A forte redução da população de 0 a 14 anos, bem como o aumento da população idosa no período mostra um processo de envelhecimento entre a população estudada. Essa configuração populacional pode comprometer a sucessão nos estabelecimentos rurais, interferindo na dinâmica social e produtiva do espaço rural da Região Central do RS.Population configuration has suffered marked changes over the last decade. Currently, the population masculinization and aging are pointed out as characteristic of such reality. Thus, this study aimed to

    A ratpid, simple, reliable method is described for assaying androgen receptor (AR) in dispersed, whole, cultured human genital skin fibroblasts (GSF) with a synthetic androgen, 3H-methyltrienolone (3H-R1881). Receptors for androgen in GSF exhiblt high affinity (Kd=3.0±0.1 nmol/L), low binding capacity and androgen specificity. The content of AR in cultured GSF from 40 normal men varying in age from 1.5—60 years u:as also investigated by this assay. Scatchard analysis and slngle plot revealed the presence of 4.500-8500 binding sites per cell, mean number of AR in GSF of these men is 6288±1082 binding sites/cell. No significant difference was observed in the content of AR in different age groups. This result showed that the content of AR in these ceils did not change with age.

    The experience of acculturation in Chinese immigrant women from the rural coastal province of Fujian has not been well studied despite of their growing numbers in American cities. This exploratory study is an attempt to examine the experience of acculturation and post-migration stress in Fujianese immigrant women as compared to those from other parts of China. The study is based on a convenience sample 240 Fujianese and 162 non-Fujianese Chinese immigrant women living in Philadelphia.Results from bivariate analyses showed that the variation in demographic characteristics between Fujianese and non-Fujianese women was marginal; that all Chinese women in this study reported experiencing a unidimensional process of acculturation and a domain-generic model of acculturation; and that the Fujianese women showed a higher level of post-migration stress than the non-Fujianese women. In multiple regression controlling for demographic characteristics and including all the women in our sample, more acculturated women reported a higher level of post-migration stress. However, separate multiple regression analyses for Fujianese and non-Fujianese women revealed a different pattern of post-migration stress models. The findings suggest the importance of further research to understand acculturation and post-migration stress among Fujianese immigrant women.

    Full Text Available BACKGROUND: The prevalence of metabolic syndrome (MetS is growing rapidly in China. Tai chi and dancing are common types of exercise among middle-aged and elderly Chinese. It remains unclear whether these activities are associated with a lower risk of MetS. METHODOLOGY/PRINCIPAL FINDINGS: A total of 15,514 individuals (6,952 men, 8,562 women aged 50 to 70 years from the Dongfeng-Tongji Cohort in Shiyan, China participated in a cross-sectional study. Physical activity and other lifestyle factors were assessed with semi-structured questionnaires during face-to-face interviews. MetS was defined by the current National Cholesterol Education Program/Adult treatment Panel III criteria for Asian Americans. The prevalence of MetS was 33.2% in the study population. In the multivariable-adjusted logistic regression analyses, total physical activity levels were monotonically associated with a lower odds of MetS [OR 0.75 comparing extreme quintiles, 95% confidence interval (CI 0.66-0.86, P<0.001]. Compared with non-exercisers in a specific exercise type, jogging (OR 0.82, 95% CI 0.68-1.00, P = 0.046, tai chi (OR 0.72, 95% CI 0.60-0.88, P<0.001, and dancing (OR 0.56, 95% CI 0.47-0.67, P<0.001 were associated with significantly lower odds of MetS. Furthermore, each 1-h/week increment in tai chi and dancing was associated with a 5% (95% CI 2%-9% and a 9% (95% CI 6%, 12% lower risk of MetS. CONCLUSIONS/SIGNIFICANCE: Jogging, tai chi and dancing are associated with a significantly lower risk of having MetS in middle-aged and older Chinese. Future intervention studies should consider the role of jogging, tai chi and dancing in preventing MetS.

    Full Text Available Background: Unwanted pregnancy is still a major problem in the modern world despite the widely available contraception services. This study was conducted to determine the knowledge and attitude of married women in the reproductive age group regarding emergency contraception in selected rural areas of Udupi district, India. Material and Methods: The study group comprised of 350 married women in the reproductive age group residing in rural areas of Udupi district, India. A structured questionnaire and an attitude scale were used to assess the knowledge and the attitude. Results: Majority, 69.1% of the married women belonged to Hindu religion, 46.9% had an educational qualification of 10th standard and below. About 13.1% of the married women had undergone abortion. Nearly 96.9% of the married women had heard about emergency contraceptives and only 2% of the married women had used emergency contraceptive pills. About 63.7% out of 339 married women had got information about emergency contraceptive pills from health personnel and about 77.7% from television. Majority 84% had poor knowledge on emergency contraception. About 99.7% had favourable attitude on the use of emergency contraceptives. There was a significant association between knowledge scores and selected variable like education, knowledge and the attitude scores had a correlation. Conclusion: The study identifies the knowledge and attitude of the rural married women regarding emergency contraception, hence to help them to plan future pregnancies and prevent any unwanted or unintended pregnancies.

    Full Text Available Estimation of population exposure is a main component of human health risk assessment for environmental contaminants. Population-level exposure assessments require time-activity pattern distributions in relation to microenvironments where people spend their time. Societal trends may have influenced time-activity patterns since previous Canadian data were collected 15 years ago. The Canadian Human Activity Pattern Survey 2 (CHAPS 2 was a national survey conducted in 2010–2011 to collect time-activity information from Canadians of all ages. Five urban and two rural locations were sampled using telephone surveys. Infants and children, key groups in risk assessment activities, were over-sampled. Survey participants (n = 5,011 provided time-activity information in 24-hour recall diaries and responded to supplemental questionnaires concerning potential exposures to specific pollutants, dwelling characteristics, and socio-economic factors. Results indicated that a majority of the time was spent indoors (88.9%, most of which was indoors at home, with limited time spent outdoors (5.8% or in a vehicle (5.3%. Season, age, gender and rurality were significant predictors of time activity patterns. Compared to earlier data, adults reported spending more time indoors at home and adolescents reported spending less time outdoors, which could be indicative of broader societal trends. These findings have potentially important implications for assessment of exposure and risk. The CHAPS 2 data also provide much larger sample sizes to allow for improved precision and are more representative of infants, children and rural residents.

    Objective To understand the associations of physical activity domains with metabolic syndrome among a middle-aged Chinese population. Methods In all, 3326 professional adults aged 35-64 years from Beijing and Zhejiang province were recruited with a cluster random sampling method. The Global Physical Activity Questionnaire was modified, and the recommended Asia-Pacific cut-offs of waist circumstance were introduced into the criteria for metabolic syndrome from the Adult Treatment Panel III. A binary logistic regression model was applied to examine the association of all physical activity domains with the risk of the syndrome. Results Participants who engaged in domestic activity for ³1176 MET-min/week had a 41.6% less chance of having metabolic syndrome [odds ratio (OR), 0.584;95%confidence interval (CI), 0.480-0.710] than those without this activity. In adjusted models, adults who actively commuted for ³33 MET-min/week but Conclusion This study highlighted the independently negative association of traffic and house activity with the prevalence of the syndrome in this sample with a generally low level of moderate activity.

    The Chinese Loess Plateau (CLP), which is located in the central part of China, mainly contains two sequences: the Quaternary loess-paleosol sequence and the late Miocene-Pliocene Red Clay sequence. U-Pb ages of detrital zircon from the Quaternary loess-paleosol sequences indicate that the current spatial pattern of central Asian aridification was largely established during the early Quaternary. U-Pb ages of detrital zircon from the underlying Red Clay sequences demonstrate that the northern source regions were important contributors for the dust since the late Miocene, except for the periods of ∼8 Ma and ∼5.5 to ∼4 Ma. These two periods correspond to increased and decreased dust deposition in the North Pacific, respectively, ascribed to the late Miocene aridification of the Qaidam Basin (in the west of the CLP) and the early Pliocene aridification of the Tarim Basin (in the west of the CLP). We attribute the increase of the Qaidam Basin-derived North Pacific dust fluxes to the uplift of the NE Tibetan Plateau. Such uplift also controlled the climatic and environmental changes in central Asian during the late Miocene. This study highlights the dynamical process of the central Asian aridification during the late Miocene-Pliocene.

    Low-density lipoprotein receptor-related protein 5 (LRP5) plays an important role in glucose and cholesterol metabolism. The present cohort study evaluated associations of LRP5 variants with the incidence of type 2 diabetes mellitus (T2DM) in a rural adult Chinese population. In all, 7751 subjects aged ≥18 years without T2DM underwent genotyping at baseline; 6326 subjects (81.62%) were followed-up, and 5511 with a clear disease outcome were eligible for analysis. The same questionnaire was administered and the same anthropometric and blood biochemical examinations were performed at baseline and follow-up. Association analysis was performed for five single nucleotide polymorphisms and haplotypes of LRP5. Cox proportional hazards testing of three different genetic models found no significant association between T2DM and LRP5 after adjusting for potential risk factors (P > 0.05). However, the incidence of T2DM in subjects with LRP5 mutational genotypes was higher in the overweight/obese than normal weight population. Under the dominant model, the risk of T2DM was increased with an interaction between rs11228303 and the waist-to-height ratio adjusted for baseline age, sex, and family history of T2DM (synergy index [SI] = 4.172; 95% confidence interval [CI] 1.014-17.166)], and body mass index (SI = 3.237; 95% CI 1.102-9.509). Furthermore, the A allele of rs3758644 was related to decreased fasting plasma insulin and homeostatic model assessment of β-cell function levels, whereas the T allele of rs12363572 was related to increased high-density lipoprotein cholesterol levels in new-onset diabetes patients (P < 0.05). The risk of T2DM may be associated with interactions between the LRP5 gene and overweight and obesity. Polymorphisms of LRP5 are related to β-cell function and lipid metabolism. © 2017 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

    This study examined how parental rural-to-urban migration may affect left-behind children's development in rural China. We used two-wave data collected on 864 rural youth age 10-17 years in the Guangxi Province, China in 2010. We tested psychometric properties of a positive youth development (PYD) model theorized and corroborated in the US, compared a range of developmental outcomes among rural youth by their parental migration status, and explored the mediating role of family economic and social resources in observed associations between developmental outcomes and parental migration. The results showed the PYD model had some international validity although modifications would be needed to make it more suitable to Chinese settings. Little difference in the PYD outcomes was detected by parental migration status. On other outcomes (i.e., self-rated health, school grades, educational aspirations, problem behavior), positive influences of parental migration were observed. Increased income but not social resources in migrant families helped explain some of these patterns. The take-home message from this study is that parental migration is not necessarily an injurious situation for youth development. To advance our knowledge about the developmental significance of parental migration for rural Chinese youth, we urgently need large-scale representative surveys to collect comprehensive and longitudinal information about rural children's developmental trajectories and their multilevel social contexts to identify key resources of PYD in order to better help migrant and non-migrant families nurture thriving youth in rural China.

    Full Text Available Background: In China, suicide is one of the major causes of death among adolescents and young adults aged 15 to 34 years. Aim: The current study examines how risk factors vary by age groups in rural China, referring to those aged 15 to 24 years and those aged 25 to 34 years. Method: A case-control psychological autopsy (PA study is conducted in sixteen counties from three Chinese provinces, including 392 suicide cases and 416 community living controls in the sample. Results: In China, young adults aged 25 to 34 years have a higher risk for suicide than adolescents aged 15 to 24 years, and it holds true even controlling for relevant social factors. In addition, age-related factors such as education, marital status, whether having children, status in the family, physical health, and personal income all have varying degrees of impact on suicide risks for rural youth. Conclusions: This study shows that there are some age-related risk factors for suicide at certain life stages and emphasizes that young adults in rural China aged 25 to 34 years have an increased risk of suicide as a result of experiencing more psychological strains with age.

    Full Text Available Abstract Background The complex mechanism of nicotine dependency makes it challenging to evaluate dependence or progress towards dependence. The aim of this study was to estimate nicotine dependence levels and identify determinants of dependence among Chinese rural-urban migrants. Methods Multi-stage systematic sampling was used to select 4,198 rural-urban migrants aged 18 years or older from three metropolises in China. A structured questionnaire was administered during face-to-face interviews. Nicotine dependence among participants was assessed by means of the six-item Mandarin Chinese Version of the Fagerström Test for Nicotine Dependence (CFTND. Determinants of dependence were analyzed using multivariate analysis of variance (MANOVA. Results Among 4,198 participants, estimated current, daily, and occasional smoking rates were 28.3%, 21.2%, and 7.1%, respectively. The CTFND score for the 894 daily smokers was 3.39(SD: 2.32. MANOVA showed that work type, age at first migration, length of migration, and number of cities ever lived were associated with nicotine dependence. Conclusion A migratory lifestyle is associated with nicotine dependence. Results could inform the design of tobacco control programs that target Chinese rural-urban migrant workers as a special at-risk population.

    Objective To investigate the epidemiological characteristics of mild cognitive impairment (MCI) among the rural elderly peoples from Cili county, Hunan Province. Methods A multi-stage stratified cluster sampling method was adopted to subject the elderly aged 60 years or above living in the rural areas of Cili county from June to December 2011. After an interview was performed by trained interviewers to the sampled subjects for a general questionnaire and Mini Mental State Examination (MMSE), those with distinct cognitive impairment or dysmnesia and those with the scores less than the cut-off point of MMSE received tests including physical examination, global deterioration scale, Hachinski ischemic scale, clinical dementia rating, and neurological examination. Then MCI was diagnosed by the consensus of 2 neurologists. Results There were 1 367 subjects (678 males and 689 females) sampled and interviewed. Among them, 178(13.02%) were positive to MMSE, and 139(10.17%) were diagnosed with MCI, and the prevalence of MCI as significantly different among the subjects of different ages, education levels, occupations, living and culture conditions and life styles (P<0.05 for all). Conclusion The older age, the lower education level, smoking, non-drinker or non-alcoholic, and the living alone may increase the incidence of MCI among the rural elderly.%目的:了解湖南省慈利县农村老年人轻度认知功能障碍(MCI)的流行病学特征。方法采用随机整群分层分阶段抽样的方法对2011年6月至12月湖南省慈利县6个乡镇、年龄≥60岁的老年人进行现况调查及筛查,完成调查问卷及简易精神状况量表(MMSE);临床诊断,对有明显记忆障碍者及MMSE分数低于界值者进一步进行临床检查,并由2名神经科医师进行最后诊断;同时进行总体衰退量表、Hachinski缺血指数量表、临床痴呆评定量表等评定。结果调查1367名,男性678名,女689名,MMSE阳性者178

  16. Age At Marriage, Gauna (Effective Marriage And First Child Birth In Rural Women- Changing Pattern In Various Marriage Cohorts By Decades

    Full Text Available Fertility patterns of a community depend upon several factors. Strict enforcement of legislation is amongst its important determinants. The Government proposes to enact a deterrent law, which will replace the loophole â€" ridden Child Marriage Restraint Act of 1978. In India, there exists a long established custom to enter into effective marriage several years after marriage. This is called ‘gauna’. Studying the various marriage cohorts by decades, the present communication comments on the age at marriage, age at gauna and age at first childbirth amongst 843 rural women in Delhi. The study shows that over the last six decades, there has been a gradual rise of age at marriage from 10.5 years to 16.5 years. However, this slope is less steep with age at gauna and almost non- existent for age at first childbirth. This in turn has narrowed the gap between age at gauna and age at first childbirth. Age at first childbirth has remained more or less constant at 19-20 years. This fining, if corroborated elsewhere also, may be of great significance and raise questions on the validity of the current strategy of increasing marriage age to 18 years in order to reduce fertility.

    Bullying among school-aged youth is a common issue worldwide and is increasingly being recognized as an important problem affecting both victims and perpetrators. Most of the bullying studies have been conducted in western countries, and their implications in other regions are limited due to different cultural contexts. The goal of our study is to identify the prevalence of bullying and its correlates school-aged youth in Guangdong province. In total, 1098 (7.1%) students reported having bullied other students, 744 (4.8%) students reported having been bullied by other students and 396 (2.6%) students reported having both bullied other students and been bullied by other students. There was a strong association between bullying others as well as being bullied and suicidal ideations, suicidal attempts, and self-harm behaviors. The prevalence of bullying and its associations with delinquent behaviors warrant the importance of school facility based preventive intervention taking into account both victims and perpetrators.

    There have been many reports about the anti-aging effect of traditional Chinese medicine (TCM), but the material basis and mechanism of action have not been clearly elucidated. AMP-activated protein kinase (AMPK) is the receptor of energy metabolism and its life extending effect has been confirmed in different experiments. Over expression or activation with metform in of AAK-2/AMPK has been shown to extend life expectancy in nematodes and Drosophila. The possible downstream pathways of AMPK against aging include TOR/S6k pathway, FOXOs pathway and CRTC pathway. One of the core concepts of traditional Chinese medicine is disease prevention, for which one of manifestations is to improve the body with the same source of medicine and food to achieve longevity. It is possible to activate AMPK to achieve the goal of health preservation and prolonging the life by some of the "medicine-food harmony" treatments. Our survey finds that in "medicine-food harmony" compound TCM, "invigorating the kidney deficiency and promoting blood circulation" class dominates and Salviae Miltiorrhizae Radix Rhizoma, Astragali Radix, Coptidis Rhizoma, Poria, Atractylodes Macrocephalae Rhizoma, Radix et Rhizoma Rhei, and Ginseng Radix et Rhizoma are used in high frequency. Network pharmacology analysis using ingenuity pathway analysis (IPA) software revealed that TCM-derived drugs interacting with AMPK target proteins included berberine, emodin, curcumin, resveratrol, alcohol, cordyceps, arctiin, suggesting in a certain extent the feasibility of "medicine -food homology" drugs to extend the lifespan through the AMPK pathway. Our study combines a comprehensive database query and an IPA network pharmacology analysis to identify Chinese medicine monomer and components that may activate AMPK pathway to delay aging and to discuss the potential of these medicine by improving energy metabolism to delay the aging process, based on the concept of traditional Chinese medicine "medicine-food homology

    It is unclear how or even if phosphorus (P) input alters the influence of nitrogen (N) deposition in a forest. In theory, nutrients in leaves and twigs differing in age may show different responses to elevated nutrient input. To test this possibility, we selected Chinese fir (Cunninghamia lanceolata) for a series of N and P addition experiments using treatments of +N1 - P (50 kg N ha(-1) year(-1)), +N2 - P (100 kg N ha(-1) year(-1)), -N + P (50 kg P ha(-1) year(-1)), +N1 + P, +N2 + P and -N - P (without N and P addition). Soil samples were analyzed for mineral N and available P concentrations. Leaves and twigs in summer and their litters in winter were classified as and sorted into young and old components to measure N and P concentrations. Soil mineral N and available P increased with N and P additions, respectively. Nitrogen addition increased leaf and twig N concentrations in the second year, but not in the first year; P addition increased leaf and twig P concentrations in both years and enhanced young but not old leaf and twig N accumulations. Nitrogen and P resorption proficiencies in litters increased in response to N and P additions, but N and P resorption efficiencies were not significantly altered. Nitrogen resorption efficiency was generally higher in leaves than in twigs and in young vs old leaves and twigs. Phosphorus resorption efficiency showed a minimal variation from 26.6 to 47.0%. Therefore, P input intensified leaf and twig N enrichment with N addition, leaf and twig nutrients were both gradually resorbed with aging, and organ and age effects depended on the extent of nutrient limitation.

    This cross-sectional exploratory study aimed to quantify and compare the axial and appendicular bone mineral density (BMD), muscle mass, and muscle strength of middle-aged practitioners of Ving Tsun (VT; a hard-style Chinese martial art) with those of nonpractitioners.Eighteen VT practitioners (mean age ± standard deviation = 51.8 ± 17.7 years; 12 men and six women) and 36 active controls (mean age ± standard deviation = 58.7 ± 11.0 years; 18 men and 18 women) participated in the study. All participants underwent a 1-day battery of musculoskeletal examinations. The BMD of the total radius, total hip, femoral neck, and lumbar spine was measured using dual-energy X-ray absorptiometry, as was the lean mass of the arm, leg, and trunk. Muscle strength of the upper and lower limbs was assessed using a Jamar dynamometer and an isokinetic dynamometer at 60°/second, respectively.VT-trained participants had a 11.5% higher total radius BMD (P = 0.023), a 17.8% higher leg lean mass (P = 0.014), a 56.4% higher isokinetic body weight-adjusted peak torque of the knee extensors (P  0.05).Middle-aged VT practitioners displayed a higher total radius BMD and leg lean mass and better knee extensor and flexor muscular performances than their healthy active counterparts. Healthcare professionals may consider using this alternative method of training to improve the musculoskeletal health of middle-aged adults.

    Full Text Available This study aimed to elucidate the associations of age, BMI, and years of menstruation with proximal femur strength in Chinese postmenopausal women, which may improve the prediction of hip fracture risk. A cross-sectional study was conducted in 1322 Chinese postmenopausal women recruited from communities. DXA images were used to generate bone mineral density (BMD and geometric parameters, including cross-sectional area (CSA, outer diameter (OD, cortical thickness (CT, section modulus (SM, buckling ratio (BR at the narrow neck (NN, intertrochanter (IT, and femoral shaft (FS. Relationships of age, BMI, and years of menstruation with bone phenotypes were analyzed with the adjustment of height, age at menarche, total daily physical activity, education, smoking status, calcium tablet intake, etc. Age was associated with lower BMD, CSA, CT, SM, and higher BR (p < 0.05, which indicated a weaker bone strength at the proximal femur. BMI and years of menstruation had the positive relationships with proximal femur strength (p < 0.05. Further analyses showed that the ranges of absolute value of change slope per year, per BMI or per year of menstruation were 0.14%–1.34%, 0.20%–2.70%, and 0.16%–0.98%, respectively. These results supported that bone strength deteriorated with aging and enhanced with higher BMI and longer time of years of menstruation in Chinese postmenopausal women.

    The Aging Semantic Differential (ASD) is the most widely used instrument to measure young people's attitudes towards older adults. This study translated the ASD to Mandarin and examined its psychometric properties. The Mandarin-ASD contains three latent factors (Personality and Mental Health, Societal Participation, and Physical) that have high internal reliability and reasonable discriminate validity. Social work researchers, practitioners and allied professionals may utilize the ASD-Mandarin instrument to measure young people's attitudes towards older adults in China. We issue a call for a universal-ASD that can be applied across different cultural contexts.

    To study, for the first time, the effect of wearing ready-made glasses and glasses with power determined by self-refraction on children's quality of life. This is a randomized, double-masked non-inferiority trial. Children in grades 7 and 8 (age 12-15 years) in nine Chinese secondary schools, with presenting visual acuity (VA) ≤6/12 improved with refraction to ≥6/7.5 bilaterally, refractive error ≤-1.0 D and refraction (SR). Main study outcome was global score on the National Eye Institute Refractive Error Quality of Life-42 (NEI-RQL-42) after 2 months of wearing study glasses, comparing other groups with the U group, adjusting for baseline score. Only one child (0.18%) was excluded for anisometropia or astigmatism. A total of 426 eligible subjects (mean age 14.2 years, 84.5% without glasses at baseline) were allocated to U [103 (24.2%)], RM [113 (26.5%)], R [108 (25.4%)] and SR [102 (23.9%)] groups, respectively. Baseline and endline score data were available for 398 (93.4%) of subjects. In multiple regression models adjusting for baseline score, older age (p = 0.003) and baseline spectacle wear (p = 0.016), but not study group assignment, were significantly associated with lower final score. Quality of life wearing ready-mades or glasses based on self-refraction did not differ from that with cycloplegic refraction by an experienced optometrist in this non-inferiority trial. © 2016 Acta Ophthalmologica Scandinavica Foundation.

    Residents aged 55 years or older from 27 communities and two settlements in Xilingol League of Inner Mongolia were selected for participation in an Alzheimer's disease epidemiological investigation from June 2008 to June 2009, including 3 259 Mongolians and 5 887 Han Chinese.The Mongolian subjects in the Alzheimer's disease group were at age of 55 years or older (on average), and more of them were male, illiterate and/or had a history of coronary artery disease and/or diabetes compared with the Mongolian subjects in the non-Alzheimer's disease group. The Han Chinese subjects in the Alzheimer's disease group were at age of 55 years or older (on average) and more of them were women, illiterate and/or had a history of coronary artery disease,and less of them had a history of alcohol consumption compared with the non-Alzheimer's disease group. Non-conditional multivariate stepwise logistic regression identified that male gender,increasing age and having a history of diabetes and/or coronary heart disease were associated with higher odds of Alzheimer's disease among Mongolians while having an educational background was associated with lower odds (OR = 0.259, 95%CI 0.174-0.386). Among the Han Chinese subjects, male gender, increasing age and having a history of coronary heart disease and/or hypertension was associated with higher odds of Alzheimer's disease, while having an educational background was associated lower odds (OR = 0.271, 95%CI 0.192-0.381). The results also indicated that extremely heavy smoking may be a risk factor for Alzheimer's disease in Mongolian males aged over 55 years. There was no significant difference in smoking habits between the Mongolian and Han Chinese subjects with Alzheimer's disease.

    The paper against a series of issues of new rural social old-age insurance in our country, such as low level of security, being lack of endogenous adjustment mechanisms. On the basis of continuation "basic pension + personal account" mode, individual voluntary sub-file payment and the same funding sources of new rural social pension insurance system, we devised basic pension payment criterion and personal funding contribution criterion of rural social old-age insurance system moderately, proposed a three-optimized design. After we set relevant parame- ters, estimated total replacement rate of pension and moderate level of pension expense with mathematical models, drawn basic conclusions and recommendations for further research. Core contents and conclusions of this paper main include following three aspects : Firstly, although according to "basic pension + personal account" mode, individual voluntary sub-file payment and the same funding sources, however, improved payment standards of basic pension, personal contributions standards and allowances of local governments, basic pension payment standards are identified as one-third of national per capita net income of farmers in china, with the increase of national per capita net income of farmers, basic pension standard linkage spontaneous growth, at the same time, basic pension standard dovetail with the relative poverty line, established a dynamic, long-term payment mechanism, setting and adjustment of individual contributions based on the per capita net income of farmers, formation a spontaneous linkage mechanism, local government in accordance with 30% of individual contributions to subsidize, implementing "more contributions more gains" principle, also established a dynamic, long-term funding contributions mechanisms. Therefore, optimal design of these three programs to support the design of institutional arrangements of new rural social old-age insurance, and established endogenous adjustment

    Background: The WHO recommends exclusive breastfeeding (EBF) for the first 6 mo of life. Objective: The objective of this study was to assess the benefit of EBF to age 6 mo on growth in a large sample of rural Gambian infants at high risk of undernutrition. Methods: Infants with growth monitoring from birth to 2 y of age (n = 756) from the ENID (Early Nutrition and Immune Development) trial were categorized as exclusively breastfed if only breast milk and no other liquids or foods were given. EBF status was entered into confounder-adjusted multilevel models to test associations with growth trajectories by using >11,000 weight-for-age (WAZ), length-for-age (LAZ), and weight-for-length (WLZ) z score observations. Results: Thirty-two percent of infants were exclusively breastfed to age 6 mo. The mean age of discontinuation of EBF was 5.2 mo, and growth faltering started at ∼3.5 mo of age. Some evidence for a difference in WAZ and WHZ was found between infants who were exclusively breastfed to age 6 mo (EBF-6) and those who were not (nEBF-6), at 6 and 12 mo of age, with EBF-6 children having a higher mean z score. The differences in z scores between the 2 groups were small in magnitude (at 6 mo of age: 0.147 WAZ; 95% CI: −0.001, 0.293 WAZ; 0.189 WHZ; 95% CI: 0.038, 0.341 WHZ). No evidence for a difference between EBF-6 and nEBF-6 infants was observed for LAZ at any time point (6, 12, and 24 mo of age). Furthermore, a higher mean WLZ at 3 mo of age was associated with a subsequent higher mean age at discontinuation of EBF, which implied reverse causality in this setting (coefficient: 0.060; 95% CI: 0.008, 0.120). Conclusion: This study suggests that EBF to age 6 mo has limited benefit to the growth of rural Gambian infants. This trial was registered at http://www.isrctn.com as ISRCTN49285450. PMID:28003540

    Full Text Available ApoE gene polymorphism has been reportedly associated with serum lipids and cognition. However, very few studies have explored the combined effects of ApoE gene polymorphism and gender on serum lipid profile with subsequent impacts on cognition in Chinese population. A total of 1,000 Chinese community dwellers aged 55 years and above were recruited in this cross-sectional study. Demographic information of the participants was collected using well designed self-administered questionnaires. The Montreal Cognitive Assessment (MoCA test was employed to evaluate the cognitive status of the participants. Semi-quantitative food frequency questionnaire (FFQ was used to obtain the dietary intake information. Fasting venous blood samples were taken for ApoE genotyping and serum lipid measurements. Significant gender differences in cognition, serum lipid profile and dietary fat-rich foods consumption were observed (p < 0.05. Cognition of the subjects was found to be associated with ApoE genotypes (p < 0.05. ApoE rs429358 and rs7412 variants demonstrated a significant effect on cognitive performance in the male subjects; especially within the attention and language cognitive domains as well as the total MoCA score (p < 0.05, respectively. Serum lipid profile and cognition of Chinese adults are significantly linked with gender and ApoE genetic polymorphism. The ApoE variant rs429358 is found to be notably associated with cognition in aging male Chinese population.

    Full Text Available BACKGROUND: Many studies have reported prevalence of overweight and obesity in children and adolescents from urban areas as well as of underweight or malnutrition from rural areas. With changing lifestyles everywhere, a need was felt to study the prevalence of overweight and obesity among rural children also. METHODOLOGY: Present cross-sectional study was planned involving 210 school children (103 boys and 107 girls of age 6-9 years from various private schools of district Una, Himachal Pradesh, India. IOTF (International Obesity Task Force cutoffs for BMI were used. Information about lifestyle, eating habits, physical activity and socio-economic status was collected through well designed questionnaire, which was filled by the parents of the children. The population studied mostly belonged to lower and upper middle class. SPSS version 17.0 was used to analyze the data. RESULTS: Overweight and obesity among children was found to be 14.8%. Time spent in physical activity has reduced greatly; also there was increased sedentary lifestyle among rural children. 93.5% of overweight and obese children were considered fine (according to their weight by their parents. The children, who did not have their food timely, ate less frequently and ate junk food more than 3-times a week, were found to be more overweight and obese. CONCLUSION: Percentage of overweight and obese children (14.8% seen in the study has provided evidence that it is not only the urban population or the higher socioeconomic class groups that are affected with the lifestyle related problems but changing lifestyle has affected rural children also.

    Food is an important part of resident consumption and its changes in quantity and structural can directly reflect the resident living level.Since the 90s of the 20 th century,with the continuous and rapid development of the economy in China,residents are much richer than before,and the urban and rural resident food consumption structure is undergoing a tremendous change,which would have an important impact on agricultural production and food security of our country to some extent.Therefore,the research on resident food consumption change attracts more and more scholars′ academic concerns.Our Chinese scholars mainly research on the changes of resident food consumption from economic value and weight aspects at present.As the volatility of market value and diversity of food consumption pattern,the above research methods can't objectively measure the resident food consumption structure changes.Therefore,to avoid the above shortcomings,this paper contrasts the quantitative relationship of animal food and vegetarian food separately in weight,energy and emergy forms and quantitatively analyzes the change tendency of Chinese urban and rural resident food consumption based on emergy analysis theory.The research results show that Chinese resident animal food consumption in weight and energy forms were 11.90% and 9.11% of vegetarian diet,while that in emergy form was 70.29%.As the values of Chinese resident animal food consumption in weight and energy forms was far below its vegetarian consumption,Chinese urban and rural resident food consumption was still vegetarian diet.But the value of its resident animal food consumption in emergy form was far more than its vegetable consumption,which means that the healthy development of animal husbandry is an important part of guaranteeing resident food consumption and national food security and it would conduce to the succession of diversity and balanced nutrition.At the same time,Chinese urban and rural resident food consumption

Sleeping time was longer in rural areas than in urban areas for different age groups, geographic regions and gender. Overall, 60.7% of the population didn't have daytime napping, 30.4% had daytime napping less than 1 h and 8.9% had day time napping more than 1 h. The proportion of non-nappers was higher among women (62.5%) than men (59.1%), rural areas (65.0%) higher than urban areas (54.3%), and western (66.6%) higher than central (58.1%) and eastern (58.8%) region. Conclusion Residents in rural areas had more sleeping time than urban areas. Proportion of nappers decreased in Chinese population in recent years. Further research was needed to examine the association

    Full Text Available We examined the effect and relative contributions of different types of stress on the risk of hypertension. Using cluster sampling, 5,976 community-dwelling individuals aged 40-60 were selected. Hypertension was defined according to the Seventh Report of the Joint National Committee, and general psychological stress was defined as experiencing stress at work or home. Information on known risk factors of hypertension (e.g., physical activity levels, food intake, smoking behavior was collected from participants. Logistic regression analysis was used to determine the associations between psychological stress and hypertension, calculating population-attributable risks and 95% confidence intervals (CIs. General stress was significantly related to hypertension (odds ratio [OR] = 1.247, 95% CI [1.076, 1.446]. Additionally, after adjustment for all other risk factors, women showed a greater risk of hypertension if they had either stress at work or at home: OR = 1.285, 95% CI (1.027, 1.609 and OR = 1.231, 95% CI (1.001, 1.514, respectively. However, this increased risk for hypertension by stress was not found in men. General stress contributed approximately 9.1% (95% CI [3.1, 15.0] to the risk for hypertension. Thus, psychological stress was associated with an increased risk for hypertension, although this increased risk was not consistent across gender.

    Young children are using digital technology (DT) devices anytime and anywhere, especially with the invention of smart phones and the replacement of desktop computers with digital tablets. Although research has shown that parents play an important role in fostering and supporting preschoolers' developing maturity and decisions about DT use, and in protecting them from potential risk due to excessive DT exposure, there have been limited studies conducted in Hong Kong focusing on parent-child DT use. This study had three objectives: 1) to explore parental use of DTs with their preschool children; 2) to identify the DT content that associated with child behavioral problems; and 3) to investigate the relationships between approaches adopted by parents to control children's DT use and related preschooler behavioral problems. This exploratory quantitative study was conducted in Hong Kong with 202 parents or guardians of preschool children between the ages of 3 and 6 attending kindergarten. The questionnaire was focused on four aspects, including 1) participants' demographics; 2) pattern of DT use; 3) parenting approach to manage the child's DT use; and 4) child behavioral and health problems related to DT use. Multiple regression analysis was adopted as the main data analysis method for identifying the DT or parental approach-related predictors of the preschooler behavioral problems. In the multiple linear regression model, the 'restrictive approach score' was the only predictor among the three parental approaches (B:1.66, 95% CI: [0.21, 3.11], p parents play a crucial role in fostering appropriate and safe DT use. It is suggested that parents practice a combination of restrictive, instructive and co-using approaches, rather than a predominately restrictive approach, to facilitate their child's growth and development. Further studies are needed to explore the parent-child relationship and parents' self-efficacy when managing the parent-child DT use, to develop

    Tacilta Nhampossa

    Full Text Available Diarrheal disease remains a leading cause of illness and death, particularly in low-income countries. Its burden, microbiological causes and risk factors were examined in children aged 0-59 months living in Manhiça, rural southern Mozambique.Trends of diarrhea-related burden of disease were estimated during the period 2001-2012. A prospective, age-stratified and matched (by age, gender and geographical origin, case-control study was conducted during 2007-2011. Clinical, epidemiology, anthropometric measurement and fecal samples obtained from recruited children were used to estimate moderate-to-severe diarrhea (MSD weighted attributable fractions.Over the last decade the incidence of acute diarrhea has dropped by about 80%. Incidence of MSD per 100 child years at risk for the period 2007-2011 was 9.85, 7.73 and 2.10 for children aged 0-11, 12-23 and 24-59 months respectively. By adjusted population attributable fractions, most cases of MSD were due to rotavirus, Cryptosporidium, ETEC ST (ST only or ST/LT, Shigella and Adenovirus 40/41. Washing hands and having facilities to dispose child's stools were associated with a reduced risk of MSD, while giving stored water to the child was associated with an increased risk of MSD.Despite the predominantly decreasing trends observed throughout the last decade, diarrheal diseases remain today a major cause of morbidity among children aged 0-59 months living in this rural Mozambican area. Rotavirus, cryptosporidium, Shigella, ETEC ST and Adenovirus 40/41 were the most important aetiologies of MSD. Thus, well-known preventive strategies such as washing hands, improving the treatment of stored water, having facilities to dispose children stools, and accelerating the introduction of the rotavirus vaccine should be promoted on a wider scale to reduce the current burden of diarrheal diseases.

    Full Text Available This study used con-beam computed tomography (CBCT to investigate the prevalence and severity of alveolar bone loss in middle-aged (40-59 years Chinese with chronic periodontitis.The study group comprised 145 dentate individuals aged 40 to 59 years residing in China who suffered from chronic periodontitis. CBCT and the application of NNT software were used to examine the level and location of alveolar bone loss.The study revealed that 40-59 year old patients with chronic periodontitis had severe bone loss. At 5,286 sites (34.7%, alveolar bone loss was mild; severe alveolar bone loss was found at 5,978 sites (39.2%. A comparison of bone loss in different jaws revealed that the area with the highest degree of bone loss was on the lingual side of the maxillary molar (56.3 ± 7.2%, and that the area with the lowest degree was primarily on the lingual side of the mandibular canine (27.5 ± 6.3%. There was a lower degree of alveolar bone loss in males than females. Differences were observed when comparing the incidence of bone loss between males and females (P < 0.05. Menopause in females and smoking in both genders may affect the level of bone loss. Male smokers experienced a greater degree of bone loss (41.67 ± 5.76% than male non-smokers (32.95 ± 4.31%. A 42.23 ± 6.34% bone loss was found in menopausal females versus 31.35 ± 3.62% in non-menopausal females.The study revealed that different sites and teeth exhibited a diverse degree of bone loss. In middle-aged patients with chronic periodontitis, the highest degrees of bone loss in the incisors, premolars, and molars were on the lingual side, mesial side and lingual side, respectively. Menopause in females and smoking may affect the level of bone loss.

    Asthma and allergies are world-wide common chronic diseases among children and young people. Little information is available about the prevalence of these diseases in rural areas of Latin America. This study assesses the prevalence of symptoms of asthma and allergies among children in urban and rural areas at Oropeza Province in Bolivia. The Spanish version of the ISAAC standardized questionnaire and the ISAAC video questionnaire were implemented to 2584 children attending the fifth elementary grade in 36 schools in Oropeza province (response 91%). Lifetime, 12 months and severity prevalence were determined for asthma, rhinitis and eczema symptoms. Odds ratios (OR) with 95% confidence intervals (95% CI) were calculated adjusting for age using generalized linear mixed-effects models. Median age of children was 11 years, 74.8% attended public schools, and 52.1% were female. While children attending urban schools had lower prevalence of self-reported wheeze in the written questionnaire (adjusted OR 0.6; 95% CI 0.4-1.9), they were more likely than children attending rural schools to report wheeze in the video questionnaire (aOR 2.1; 95% CI 1.0-2.6). They also reported more frequently severe rhinoconjunctivitis (aOR 2.8; 95% CI 1.2-6.6) and severe eczema symptoms (aOR 3.3; 95% CI 1.0-11.0). Overall in accordance with the hygiene hypothesis, children living in urban areas of Bolivia seem to have a higher prevalence of symptoms of asthma and allergies compared to children living in the country side. In order to develop primary prevention strategies, environmental factors need to be identified in future studies.

    Full Text Available No processo de envelhecimento populacional, em território rural, as redes de apoio social são fundamentais para a reprodução do grupo que, por força da tradição destaca-se a família como unidade essencial de cooperação econômica e principal fonte de apoio social. As transformações no território afetam, reciprocamente, as possibilidades desse apoio. No contexto desse artigo, foram enfocados aspectos do apoio social entre famílias de campesinos idosos tendo como referência a noção de rede social em território rural e como universo empírico duas comunidades rurais (São Pedro e Retiro São Bento, no distrito de Joselândia, município de Barão de Melgaço/MT. Trata-se de estudo orientado pela perspectiva socioantropológica, que permitiu apreender os pontos de vista dos sujeitos, valendo-se da abordagem qualitativa. Foram entrevistados 18 idosos, pertencentes a 11 famílias, sendo 8 delas de São Pedro e 3 de São Bento. De modo geral, os moradores idosos entrevistados não desvinculam a dimensão física da terra, da sua simbologia - que é todo o sentido de sua existência. O parentesco, a amizade e a identidade interligam as pessoas em relações de reciprocidade, por diversos motivos, em situações cotidianas, chamando a atenção para o papel dos vínculos para a manutenção da saúde. As redes de apoio se ampliam, no caso do cuidado com as doenças, e outras são estabelecidas para o acesso aos serviços de saúde. Essa elasticidade/plasticidade da rede para o apoio coaduna-se à noção de territorialidade pela sua conotação material e simbólica.In the process of population aging in rural area, social support networks are essential for the reproduction of the group in which, due to tradition in the rural area, the family stands out as an essential unit of economic cooperation and main source of social support in this context.

    A group of mesh-based and age-dependent family phantoms for Chinese populations were developed in this study. We implemented a method for deforming original RPI-AM and RPI-AF models into phantoms of different ages: 5, 10 ,15 and adult. More than 120 organs for each model were processed to match with the values of the Chinese reference parameters within 0.5%. All of these phantoms were then converted to voxel format for Monte Carlo simulations. Dose coefficients for adult models were counted to compare with those of RPI-AM and RPI-AF. The results show that there are significant differences between absorbed doses of RPI phantoms and these of our adult phantoms at low energies. Comparisons for the dose coefficients among different ages and genders were also made. it was found that teenagers receive more radiation doses than adults under the same irradiation condition. This set of phantoms can be utilized to estimate dosimetry for Chinese population for radiation protection, medical imaging, and radiotherapy.
