Novel anthropometric indices are superior adiposity indexes to portend visual impairment in middle-aged and older Chinese population. BMJ Open Ophthalmol 2024; 9:e001664. [PMID: 39009464 PMCID: PMC11253769 DOI: 10.1136/bmjophth-2024-001664] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2024] [Accepted: 05/06/2024] [Indexed: 07/17/2024] Open
Abstract
OBJECTIVE To investigate differential associations of traditional and novel adiposity indices with visual impairment (VI) in the middle-aged and older Chinese population. METHODS AND ANALYSIS Based on the China Health and Retirement Longitudinal Study, 7750 Chinese older adults aged over 45 were included at baseline 2011, and 4133 participants who accomplished all three interviews from 2011 to 2015 were adapted for longitudinal analyses. We enrolled six adiposity indices, including the body mass index (BMI), waist-to-height ratio (WHtR), weight-adjusted-waist index (WWI), a body shape index (ABSI), body roundness index (BRI) and conicity index (ConI). Visual status and other covariates included sociodemographic characteristics, medical supports and lifestyle-related factors. Cross-sectional correlations were assessed using univariate and multivariate logistic regression analyses. For longitudinal analysis, generalised linear models with generalised estimating equations were used to determine the association between time-varying adiposity and visual status. RESULTS Higher levels of WHtR/WWI/ABSI/BRI/ConI were significantly associated with an increased prevalence of VI, whereas a higher BMI was associated with a decreased prevalence of VI. Only WWI was significantly related to the prevalence of VI after adjustment for multiple confounders in both cross-sectional and longitudinal analyses (all p values <0.05). The multivariable-adjusted OR (95% CI) of VI associated with the highest (vs lowest) quintile of WWI was 1.900 (1.407 to 2.565). CONCLUSION WWI is a reliable alternative adiposity index that exhibits a dose-response association with the prevalence of VI in the Chinese population. The WWI-VI correlation may eliminate the obesity paradox in the ophthalmic epidemiological area and indicate the detrimental impact of changes in body composition on VI.

Abstract
Obesity is a major risk factor for hypertension, type 2 diabetes and other morbidities. On the other hand, hypertension is a leading cause of cardiovascular disease. The presence of obesity in hypertensive persons increases cardiovascular risk and related mortality. Data on the prevalence of obesity and hypertension in academic staff in Bangladesh are scarce. This study aimed to determine the prevalence and factors associated with obesity and hypertension among university academic staff in Bangladesh. In total, 352 academic staff were enrolled in this study from two universities in Bangladesh. A pre-structured questionnaire was used to obtain data on anthropometric, demographic and lifestyle-related factors. Bivariate and multivariate logistic regression analyses were performed to assess the factors associated with obesity and hypertension. Overall, the prevalence of general and abdominal obesity and hypertension was 26.7%, 46.9% and 33.7%, respectively. Female staff had a significantly higher prevalence of both general and abdominal obesity (41% and 64.1%, respectively) than male staff (21.5% and 34.9%, respectively) (p < 0.001). In contrast, male staff had a higher prevalence of hypertension (36.9%) than female staff (25.6%)(p < 0.001). An increased prevalence of hypertension was found in the higher BMI and WC groups of the participants. The prevalence of general obesity, abdominal obesity and hypertension was higher in the 30-40 years, > 50 years and 41-50 years age groups, respectively. According to the regression analysis, female gender and inadequate physical activity were independently associated with general and abdominal obesity. On the other hand, increased age, BMI, WC, presence of diabetes and smoking showed a significant association with hypertension. In conclusion, the prevalence of obesity and hypertension was higher among university academic staff members in Bangladesh. Our findings suggest that comprehensive screening programs are needed to facilitate the diagnosis, control, and prevention of obesity and hypertension in high-risk population groups.

Abstract
Background Obesity and hypertension are global health concerns. Both are linked with increased risks of all-cause and cardiovascular mortality. Several early studies reported the prevalence of obesity and hypertension in Bangladeshi adults, but the associated factors in this country population are not clear yet. We aimed to estimate the prevalence and related risk factors of general and abdominal obesity and hypertension in rural and urban adults in Bangladesh. Methods In this cross-sectional study, data (n = 1410) was collected on rural (n = 626) and urban (n = 784) adults from eight divisional regions of Bangladesh. Both anthropometric and socio-demographic measurements were recorded in a standardized questionnaire form. General and abdominal obesity were defined based on WHO proposed cut-off values and hypertension was defined by SBP ≥ 140 mmHg and/or, DBP ≥ 90 mmHg and/or, intake of anti-hypertensive drugs at the time of data collection. Multivariable logistic regression analyses were performed to assess the relationship of general and abdominal obesity and hypertension with various factors. Results The overall prevalence of general obesity, abdominal obesity and hypertension was 18.2, 41.9 and 30.9%, respectively. The women had a higher prevalence of general obesity (25.2%), abdominal obesity (56.1%) and hypertension (32.3%) compared to the men (12.2, 29.0, and 29.7%, respectively). The prevalence of both general and abdominal obesity was higher in urban participants (21.7 and 46.6%, respectively) than in the rural participants (13.8 and 35.1%, respectively), whereas, the rural participants had a higher prevalence of hypertension (35.1%) compared to the urban participants (27.5%). In geographical region comparison, the prevalence of general and abdominal obesity and hypertension were higher in participants enrolled from Dhaka (30.8%), Khulna (63.6%) and Mymensingh (43.5%) regions, respectively compared to other regions. In regression analysis, increased age, place of residence and less physical activity were positively associated with the increased risk of both types of obesity and hypertension. The analysis also showed a significant positive association between high BMI and an increased risk of hypertension. Conclusion This study shows a high prevalence of obesity and hypertension in rural and urban adults. Increased age, inadequate physical activity and place of residence were significant determinants of general and abdominal obesity and hypertension. A comprehensive intervention program focusing on modifiable risk factors such as lifestyles and food habits is needed to increase awareness and prevent the burden of obesity and hypertension in the Bangladeshi population.

Abstract
Hypertension is a major cause of cardiovascular disease and related mortality worldwide. The presence of general and abdominal obesity in hypertensive individuals increases the risk of cardiovascular mortality. However, evidence on the burden of obesity and hypertension and associated factors are lacking or limited among young adult students in Bangladesh. This study measured the prevalence and factors associated with general and abdominal obesity and hypertension among university students in Bangladesh. In this study, a total of 1011 students (647 males and 364 females) were enrolled on nine public universities in eight divisional regions of Bangladesh. Data were collected on socio‐demographic, anthropometric, and lifestyle in a questionnaire form. Unadjusted and adjusted logistic regression analyses were performed to evaluate the association of general obesity, abdominal obesity and hypertension with different factors. The prevalence of general obesity, abdominal obesity and hypertension was 8.3%, 20.7%, and 10.2%, respectively. The females had a higher prevalence of general obesity (8.8%) and abdominal obesity (26.3%) compared to the males (8.0% and 17.7%, respectively). However, a higher prevalence of hypertension was observed in males (12.2%) than in the female (6.1%) patients. In regression analysis, age showed a significant association with general obesity, whereas, age and female sex were significantly associated with abdominal obesity. The analysis also identified the male sex and high BMI as the increased risk factors for hypertension. Our study suggests a comprehensive screening program and campaigns to increase awareness about obesity and hypertension and its risk factors among young adults in Bangladesh.

Abstract
Several studies have assessed the relationship between alcohol intake and overweight/obesity; however, the reported results are inconsistent. Therefore, the present systematic review and dose-response meta-analysis of observational studies was designed to investigate the association between alcohol intake and general and abdominal obesity among the adults. Literature search was conducted in the PubMed/Medline and Web of Science databases up to August 2020. Odds ratio (OR), risk ratio (RR), or hazard ratio (HR) with 95% confidence interval (95% CI) were used to pool effect size. To conduct dose-response meta-analysis, amount of alcohol intake was classified into three categories including light (<14 g/d), moderate (14-28 g/d), and heavy (>28 g/d). In the present study, 127 eligible studies were included. In cohort studies, there was no significant association between alcohol drinking and risk of overweight (OR: 0.93, 95% CI: 0.46 to 1.89), obesity (OR: 0.84, 95% CI: 0.52 to 1.37), overweight/obesity (OR: 1.15, 95% CI: 0.84 to 1.58), and abdominal obesity (OR: 1.13, 95% CI: 0.90 to 1.41). In cross-sectional studies, alcohol intake was associated with the increased odds of overweight (OR: 1.11, 95% CI: 1.05 to 1.18), overweight/obesity (OR: 1.23, 95% CI: 1.11 to 1.37), and abdominal obesity (OR: 1.19, 95% CI: 1.09 to 1.29); but not obesity (OR: 1.03, 95% CI: 0.95 to 1.12). Results of dose-response analysis indicated that heavy alcohol drinking was positively associated with odds of overweight (OR: 1.12, 95% CI: 1.01 to 1.24), overweight/obesity (OR: 1.32, 95% CI: 1.16 to 1.51), and abdominal obesity (OR: 1.25, 95% CI: 1.12 to 1.38) compared to non- or light alcohol drinking. There was no publication bias among studied on outcomes of interest. In conclusion, our results revealed alcohol drinkers, especially heavy alcohol drinkers, had increased odds of overweight, overweight/obesity, and abdominal obesity than non-alcohol drinker or light alcohol drinkers among cross-sectional studies but not cohort studies.

Abstract
BACKGROUND To assess the associations of body mass index (BMI) with all-cause and cause-specific mortalities among rural Chinese. METHODS A prospective study of 28 895 individuals was conducted from 2006 to 2014 in rural Deqing, China. Height and weight were measured. The association of BMI with mortality was assessed by using Cox proportional hazards model and restricted cubic spline regression. RESULTS There were a total of 2062 deaths during an average follow-up of 7 years. As compared with those with BMI of 22.0-24.9 kg/m2, an increased risk of all-cause mortality was found for both underweight men (BMI <18.5 kg/m2) (adjusted HR (aHR): 1.45, 95% CI: 1.18 to 1.79) and low normal weight men (BMI of 18.5-21.9 kg/m2) (aHR: 1.20, 95% CI: 1.03 to 1.38). A J-shaped association was observed between BMI and all-cause mortality in men. Underweight also had an increased risk of cardiovascular disease and cancer mortalities in men. The association of underweight with all-cause mortality was more pronounced in ever smokers and older men (60+ years). The results remained after excluding participants who were followed up less than 1 year. CONCLUSION The present study suggests that underweight is an important predictor of mortality, especially for elderly men in the rural community of China.

Abstract
UNLABELLED The aim of this study was to explore association of physical activity and sitting time with overweight/obesity in Chinese occupational populations for the development of intervention and prevention strategies for obesity. METHODS A total of 23,112 participants were selected from the 2010-2012 China National Nutrition and Health Survey (CNNHS). A logistics regression model was used to examine the associations of physical activity and sitting time with overweight/obesity by gender after adjusting for age, educational level, marital status, and family economic level. RESULTS The prevalence of overweight/obesity based on the WHO definition and the WGOC definition was 30.8% and 41.3%, respectively. Male employees with moderate and heavy occupation activity intensity had a lower risk for overweight/obesity than those with light occupation activity intensity (moderate: OR 0.90, 95% CI 0.82-0.98; heavy: OR 0.75, 95% CI 0.65-0.86), and the risk of overweight/obesity of male employees with long work-time spent sitting was higher than those with short work-time spent sitting (2-4.9 h/day: OR 1.26, 95% CI 1.14-1.40; ≥5 h/day: OR 1.29, 95% CI 1.15-1.44). The risk of overweight/obesity of male employees with active transportation mode was lower than those with inactive transportation mode (OR 0.91, 95% CI 0.84-0.99), while the risk of overweight/obesity of female employees with active transportation mode was higher (OR 1.14, 95% CI 1.04-1.25). Female employees with leisure-time physical activity (LTPA) for ≥150 min/week had lower risk of overweight/obesity than those with LTPA for <150 min/week (OR 0.69, 95% CI 0.56-0.84). There was no significant association of leisure-time sitting and housework time with overweight/obesity in Chinese occupational populations. CONCLUSION Occupation activity intensity, LTPA, transportation mode, and work sitting time were associated with overweight/obesity. Reducing work sitting time, moderate and heavy occupation activity intensity, and an active transportation mode could help male employees decrease the risk of overweight/obesity. Increasing leisure-time physical activity could reduce the risk of overweight/obesity in women. Our findings provided insight into the association of physical activity and sitting time with overweight/obesity. It will be necessary to carry out workplace-based interventions, have an active transportation mode, and increase leisure-time physical activity to decrease the risks of overweight/obesity.

Abstract
Background Obesity is a major public health concern worldwide including Bangladesh. This study aimed to assess the prevalence and associated risk factors of general and abdominal obesity in rural and urban women in Bangladesh. Methods A total of 450 adult women aged ≥ 18 years were recruited from rural (n = 210) and urban (n = 240) areas of four administrative regions (Chattagram, Dhaka and Rajshahi and Sylhet) of Bangladesh. Both socio-demographic and anthropometric data were recorded in this study. WHO proposed cut-off values were used for the Asian population for defining general and abdominal obesity. Multinomial logistic regression analysis was applied to evaluate the risk factors of general and abdominal obesity for Bangladeshi women. Results Overall, the prevalence of general and abdominal obesity was 28% and 49%, respectively. Urban women had a significantly higher prevalence of both general and abdominal obesity (30.9% and 58.6%, respectively) than in the rural women (26.6% and 38.1%, respectively) (p<0.05 and p<0.01, respectively). As region comparison, the prevalence of general obesity was higher in the Dhaka region (39.3%) compared to the Chattragram (23.3%), Rajshahi (23.9%) and Sylhet (3.5%) regions. On the other hand, abdominal obesity was more frequent among participants in Sylhet (72.4%) and Dhaka regions (61.5%), compared to the Chattagram (27.4%) and Rajshahi (37.3%) regions. A wide variation has been observed on the prevalence of general and abdominal obesity in the different age groups of the four regions. In regression analysis, a high socioeconomic status (ref: low socioeconomic level), low education level (ref: higher education), low physical activity (ref: adequate physical activity) and middle age (ref: ≥ 30 years of age) were significant risk factors for general and abdominal obesity. Conclusions The prevalence of general and abdominal obesity was higher among participants living in urban areas. Physical inactivity, middle age, high socioeconomic status and low education level were associated with the increased prevalence of general and abdominal obesity. Such a high prevalence of general and abdominal obesity is a health concern for Bangladeshi women; therefore, public awareness and effective health intervention strategies are needed to address these conditions.

Abstract
OBJECTIVES The aim of this study was to evaluate hypertension risk associated with long- and short-term body mass index (BMI) changes. METHODS This prospective cohort study included four examinations: 2004 to 2006, 2008, 2010, and 2017. Adjusted Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of BMI changes on incident hypertension. The difference of β coefficients between long- and short-term BMI changes were examined using Fisher Z-test. RESULTS Relative to stable, normal BMI, both long- and short-term elevated BMI conferred an increased risk for hypertension, with HRs of 1.507 (95% CI, 1.286-1.767) and 1.197(95% CI, 1.019-1.405), respectively. In contrast, relative to stable overweight, both long- and short-term decreased BMI conferred a reduced risk for hypertension, with HRs of 0.651(95% CI, 0.536-0.789) and 0.775 (0.625-0.962), respectively. Additionally, for BMI changing from normal to overweight, long-term changes were relatively more strongly associated with increased risk for incident hypertension than short-term based on regression coefficients (β = 0.410 versus β = 0.179, P < 0.001). For BMI changing from overweight to normal, long-term changes were relatively more strongly associated with lower risk than short-term based on regression coefficients (β = -0.430 versus β = -0.254, P = 0.007). Additionally, there was no correlation between absolute changes in BMI and systolic blood pressure for long- (P = 0.744) and short-term (P = 0.097). CONCLUSION For participants with normal BMI, risk tended to be higher in adults whose elevated BMI occurred during the long-term. For those who are overweight, long-term decreased BMI can reduce the risk for incident hypertension to a greater extent. No correlation was found between absolute changes in BMI and systolic blood pressure.

Abstract
BACKGROUND Obesity and overweight are becoming major health concerns worldwide. Hence, we studied the association between overweight and obesity with new-onset diabetes and hypertension in a selected rural population. METHODOLOGY Community health workers made house-to-house visits, inviting adults >20 years of age who were at a higher risk of diabetes, from a predefined rural area of Maharashtra, to visit a mobile diabetes clinic operating in a hub and spoke manner. Sociodemographic data and anthropometric measurements were recorded. BMI and waist circumference was classified according to the WHO recommended cutoffs for Asians. Subjects with capillary blood fasting glucose of ≥126 mg/dL or random glucose of ≥200 mg/dL by glucometer were diagnosed as diabetes and blood pressure of ≥140/90 mmHg by sphygmomanometer were diagnosed as hypertension. Subjects with a known history of diabetes mellitus and hypertension were excluded. RESULTS Out of 29,324 total population, 16.5% of subjects were overweight and 26.4% were obese. Mean ± SD of BMI of the participants was 22.9 ± 4.1 kg/m2 in males and 22.4 ± 4.2 kg/m2 in females. Around 35% of males and 30.5% of females had a high waist circumference of ≥90 cm and ≥80 cm, respectively, 20.5% of subjects had newly diagnosed hypertension, and 11.4% of subjects had newly diagnosed diabetes mellitus. The occurrence of newly diagnosed hypertension and diabetes showed an increasing trend with increasing BMI. CONCLUSION Our community-based screening suggested a high prevalence of overweight and obesity in rural India. There was a high prevalence of newly diagnosed hypertension and diabetes in this population.

Abstract
Using data from the China Health and Nutrition Survey, this study analyses two decades (1991-2011) of change in adult obesity in China with a focus on whether rising obesity rates result from all population cohorts becoming more obese across time (intra-cohort change) or recent cohorts being more obese than their earlier counterparts (inter-cohort change or cohort replacement). To do so, we decompose changes in the body mass index (BMI), waist circumference (WC), general obesity and abdominal obesity of adults aged 20+ using both Firebaugh's linear decomposition and Das Gupta's non-linear technique. Our analysis not only reveals significant increases in both general and abdominal obesity (8.1 and 32 percentage points, respectively) in the two decades studied but shows that the rising means in all four measures are mostly attributable to intra-cohort change. In fact, contrary to findings for the U.S., inter-cohort change for the Chinese sample is actually negative, implying that cohort replacement attenuates intra-cohort change over time. Given that intra-cohort change is the central force for the increase in BMI, WC and obesity with individual increases in obesity widely distributed across all cohorts and age groups over time, policy interventions should focus more broadly on all age groups and birth cohorts.

Abstract
Objective To investigate the epidemiological features of obesity in rural Northeast China. Design This was a 2017–2018 cross-sectional study of 10,891 participants aged ≥40 years that was designed to investigate the prevalence of obesity in rural areas of Liaoning Province. Demographic data, biochemical parameters, and physical examinations were completed by well-trained personnel. Logistic regression analyses were then carried out to investigate independent risk factors and associated cardiometabolic comorbidities of obesity. Results The proportions of general obesity only, central obesity only, and combined obesity were 1.0%, 31.3%, and 17.4%, respectively. Overall, 49.8% of our subjects were obese. Female gender, being married, being separated/divorced/widowed, or eating more meat were significantly associated with obesity. Smoking, higher family income, or regular physical exercise were negatively associated with obesity. General obesity only was significantly correlated with hypertension, diabetes, and high triglycerides (OR = 2.79, OR = 2.79, and OR = 3.37, resp.). General obesity only was irrelevant to high total cholesterol, low high-density lipoprotein cholesterol, and high low-density lipoprotein cholesterol, although central obesity only, or combined obesity, was relevant to these factors. Prehypertension and prediabetes showed a positive association with different types of obesity. Conclusions We identified a high prevalence of general and central obesity in rural Northeast China, with similar independent risk factors. Participants with combined obesity had the highest risk of cardiometabolic comorbidities, indicating that the combined use of both waist circumference and body mass index is useful in practice.

Abstract
This article aims to evaluate associations between anthropometric changes in five years with lipid and blood pressure levels in Brazilian rural population. This longitudinal study evaluated 387 individuals aged 18 to 75 residents of two rural communities. Demographic, lifestyle, anthropometric, biochemical and hemodynamic characteristics were assessed in 2004 and repeated in 2009. Multivariate linear regression was used. Positive change in BMI was associated with increased diastolic blood pressure (DBP) (β = 0.07; 95%CI: 0.03-0.11), low-density lipoprotein (LDL-C) (increase of 0.01% to 10%: β = 0.08; 95%CI: 0.02-0.14, more than 10% increase: β = 0.09; 95%CI: 0.01-0.16) and low density lipoprotein/high density lipoprotein cholesterol ratio (LDL-C/HDL-C) (increase of 0.01% to 10%: β = 0.15; 95%CI: 0.06-0.25, more than 10% increase: β = 0.14; 95%CI: 0.02-0.25). Our results showed no association between positive changes in WC and lipid levels increase, only with blood pressure levels increase (SBP: β = 0.06; CI95%:0.02-0.10; DBP: β = 0.09; CI95%: 0.04;0.13). Positive changes in BMI are independent predictors of increased lipid and blood pressure levels and positive changes in WC of increased blood pressure.

Abstract
BACKGROUND Obesity has become a global epidemic. The prevalence of obesity has also increased in the South Asian region in the last decade. However, dietary and lifestyle factors associated with obesity in Sri Lankan adults are unclear. The objective of the current study was to investigate the association of dietary and lifestyle patterns with overweight and obesity in a cohort of males from the Central Province of Sri Lanka. METHODS A total of 2469 males aged between 16 and 72 years ([Formula: see text]) were included in the study. The sample comprised individuals who presented for a routine medical examination at the National Transport Medical Institute, Kandy, Sri Lanka. The Body Mass Index (BMI) cutoff values for Asians were used to categorize the participants into four groups as underweight, normal weight, overweight or obese. The data on dietary and lifestyle patterns such as level of physical activity, smoking, alcohol consumption, sleeping hours and other socio demographic data were obtained using validated self-administered questionnaires. Multinomial logistic regression model was fitted to assess the associations of individual lifestyle patterns with overweight and obesity. RESULTS The mean BMI of the study group was 22.7 kg m-2 and prevalence rates of overweight and obesity were 31.8 and 12.3%, respectively. Mean waist circumference of the participants was 78.6 cm with 17.1% of them being centrally obese. After adjusting for potential confounders, weight status was associated with older age (P < 0.0001), ethnicity (P = 0.0033) and higher income (P = 0.0006). While higher physical activity showed a trend for being associated with lower odds of being obese (odds ratio: 0.898 - confidence interval: 0.744-1.084), alcohol intake, consumption of fruits, level of education, sleeping hours, smoking, consumption of fish, meat, dairy, sweets or fried snacks were not significantly associated with the weight status. CONCLUSION The high prevalence rates of overweight and obesity in working-age males is a threatening sign for Sri Lanka. Since the prevalence rate is higher in certain ethnic groups and higher-income groups, targeted interventions for these groups may be necessary.

Abstract
Background. Family history of diabetes (FHD) and lifestyle are associated with type 2 diabetes (T2DM), but little is known about the FHD diet interactions. We aimed to analyze the interactions of FHD and lifestyle factors in Chinese T2DM onset. Methods. This was a cross-sectional survey in central urban China (n = 1234 patients with T2DM and n = 8615 non-T2DM subjects). The biological interactions, defined by Rothman interactions, between FHD and each dietary factor were analyzed by using the synergy index (S) scores. Results. After adjustment for age, gender, BMI, and WHR, a uniparental FHD (OR = 2.84, 95% CI: 2.36-3.42, P < 0.001), a paternal history of FHD (OR = 2.53, 95% CI: 1.91-3.35, P < 0.001), a maternal history of FHD (OR = 3.27, 95% CI: 2.67-4.02, P < 0.001), a biparental history of FHD (OR = 5.26, 95% CI: 2.98-9.31, P < 0.001), and a FHD, irrespective of the parent (OR = 3.59, 95% CI: 3.08-4.17, P < 0.001), were associated with T2DM onset. There were significant interactions between FHD and consuming <15 g/d of potatoes (S = 1.54, 95% CI: 1.12-2.12), <8 g/d of poultry (S = 1.51, 95% CI: 1.04-2.17), <85 g/d of fresh fruits (S = 2.17, 95% CI: 1.63-2.88), and no freshly squeezed juice (S = 2.25, 95% CI: 1.46-3.49). Conclusions. Risk of T2DM was synergistically affected by FHD and dietary habits. Nutrition educational intervention may decrease the prevalence of T2DM in the Chinese with FHD.

Abstract
In China, with fast economic growth, health and nutrition status among the rural population has shown significant improvement in the past decades. On the other hand, burden of non-communicable diseases and prevalence of related risk factors such as overweight and obesity has also increased. Among rural children, the double burden of malnutrition and emerging overweight and obesity has been neglected so far. According to the theory of Developmental Origin of Health and Diseases (DOHaD), malnutrition, including both undernutrition (stunting and wasting) and over-nutrition (overweight and obesity) during childhood is closely related to worsened health outcomes during adulthood. Such a neglected problem is attributable to a complicated synergy of social and environmental factors such as parental migration, financial situation of the household, child-rearing knowledge and practices of the primary caregivers, and has implications for public health. Based on literature review of lessons from the field, intervention to address malnutrition among rural children should be a comprehensive package, with consideration of their developmental environment and geographical and socioeconomic diversity. The scientific evidence on DOHaD indicates the probability and necessity of prevention of adult disease by promotion of maternal and child health and reducing malnutrition by provision of high-quality complementary foods, promotion of a well-balanced dietary pattern, and promotion of health literacy in the public would bring a potential benefit to reduce potential risk of diseases.

Abstract
Background Obesity has reached epidemic proportions worldwide including Bangladesh. To assess the prevalence and associated factors of general and central obesity in a rural Bangladeshi population based on newly proposed cut off level for Asian population. Methods 2293 subjects aged ≥20 years from rural Bangladesh were randomly recruited to participate in a population-based, cross sectional survey, conducted in 2009. Both socio-demographic and anthropometric measurements were recorded. Age adjusted data for anthropometric indices were examined. Results The age standardized prevalence of overweight (BMI 23-24.9 kg/m2) and obesity (BMI ≥25 kg/m2) were 17.7 (95 % confidence interval (CI): 16.1, 19.2 %) and 26.2 % (95 % CI: 24.4, 27.9 %), respectively. The age standardized prevalence of central obesity based on WC (M ≥90 & F ≥80 cm) and WHR (M ≥0.90 & F ≥0.80) were 39.8 % (95 % CI: 37.9, 41.7 %) and 71.6 % (95 % CI: 69.8, 73.4 %) respectively. The result shows that prevalence of central obesity was more in female than male. Study shows middle age, medium and high socioeconomic status (SES), low education levels, physical inactivity, high consumption of carbohydrate, protein and fat, were significant risk indicators for general and central obesity. Smoking was shown as protective factor for both general and central obesity. Conclusions In rural Bangladeshi population, the prevalence of both general and central obesity was high among both sexes with the use of newly proposed cut off points for Asian population. Gender, diet, physical activity, education levels and SES were associated with the increase prevalence of obesity.

Abstract
Background Weight change predicted diseases and mortality. We investigate 3-year changes in individual body mass index (BMI) and waist circumference in Hong Kong Chinese adults. Methods In the Population Health Survey, 7084 adults in 2003 (baseline) were followed up in 2006. Longitudinal anthropometric data were available in 2941 (41.5%) for BMI and 2956 for waist circumference. Weight status and central obesity were based on objectively measured BMI and waist circumference using Asian standards. Results Mean BMI (SD) increased from 22.8 (3.62) to 23.1 (3.95) (p<0.001) with 1.3 percentage point increase in prevalence of overweight and obesity (from 44.3% to 45.6%). One in 5 (22.0%) normal or underweight baseline respondents became overweight or obese and a similar proportion (24.8%) of overweight and obese respondents became normal or underweight. Prevalence of central obesity increased from 28.3% to 32.4% (p<0.001) with a non-significantly greater increase in women (30.0% to 38.1%) than men (23.0% to 26.1%) (p=0.63). A higher proportion of centrally obese respondents returned to normal (29.4%) than normal respondents developing central obesity (17.4%). Conclusions This is one of the few studies in Chinese, which found dynamic longitudinal changes (increase/stable/decrease) in individual weight status and waist circumference. Future studies with better follow-up and investigating the causes of such changes are warranted.

Abstract
Objectives Obesity is associated with cardiovascular diseases and has become the main public health issue in western countries and urban China. However, the prevalence and secular trends of obesity in rural China are currently unknown. The aim of this study was to investigate secular trends in the prevalence of overweight and obesity among rural adults in northern China between 1991 and 2011. Method The prevalence of overweight and obesity was assessed in adults aged 35–74 years living in a rural area in northern China by comparing two surveys that were conducted in 1991 and 2011, respectively. Result The age-adjusted prevalence of overweight increased from 24.5% in 1991 to 42.0% in 2011, and the prevalence of obesity increased from 5.7% in 1991 to 19.6% in 2011. Over the 21-year period, there were significant increases in the prevalence of overweight and obesity for both men and women in all age groups; however, the greatest increase was observed in men aged 35–44 years, with an 10.3-fold increase in obesity prevalence. The prevalence of obesity increased significantly in all risk factors categories, including education levels, blood pressure categories, diabetes previous history, current smoking situation and alcohol drinking situation over the past 21 years overall (p<0.05). The greatest increase in obesity prevalence appeared among those who consumed alcohol (increased by 8.0-fold). Next, there was a 5.3-fold increase in the prevalence of obesity in illiterate residents. Conclusion The prevalence of overweight and obesity has increased rapidly among rural adults in Tianjin over the past 21 years, with the most dramatic increase observed in young men. Therefore, the burden of obesity should serve as a call for action.

Abstract
Background Not enough is known about the prevalence of overweight and obesity in rural China in the current decade. We aim to update our knowledge of the prevalence of obesity and its associated risk factors and comorbidities in a large population sample in rural Northeast China. Methods A population-based survey of 11,579 participants aged 35 years and older was conducted in rural areas of Liaoning Province during 2012–2013. Anthropometric measurements, information on health-related variables and blood biochemical indexes were collected by well-trained personnel. Results The prevalence of general obesity and overweight was found to be 7.8% and 37.2%, respectively. The overall prevalence of abdominal obesity was 15.1%. Female gender, ethnic minority, middle-school education and a family income of 5,000–20,000 CNY per year were found to be risk factors for general obesity, while older age, female gender, ethnic minority and longer sleep duration (>8 h/d) increased the risk of abdominal obesity, after adjusting for confounders. Overweight and obese participants had significantly higher risks to develop prehypertension, hypertension, high LDL-C and low HDL-C compared with normal weight participants, while abdominal obesity was associated with increased risks of diabetes and high TG after adjusted for multiple factors. Compared with participants with a normal BMI and no abdominal obesity, the participants classified as abdominally obese and normal BMI; as abdominally obese and overweight; and abdominally obese and generally obese each had a progressive increase in the odds of hypertension (OR: 1.961, 95% CI: 1.154 to 3.331, OR: 2.744, 95% CI: 2.126 to 3.541, and OR: 8.990, 95% CI: 5.858 to 13.795, respectively) and high TG (OR: 3.165, 95% CI: 2.183 to 4.588, OR: 3.980, 95% CI: 3.332 to 4.755, and OR: 4.340, 95% CI: 3.574 to 5.271, respectively). Conclusions The prevalence of obesity in rural Northeast China exhibited a remarkably increasing upwards trend. General and abdominal obesity were associated with different subtypes of cardiometabolic comorbidities, the combined effects of which on the comorbidities dramatically increased.

Abstract
Background The last study reported the prevalence of Metabolic Syndrome (MetS) in rural Northeast China was conducted approximately ten years ago. We aimed to update the data on the prevalence and epidemiological features of MetS in rural Northeast China. Methods This survey was conducted from July 2012 to August 2013. In this study, a total of 11,496 residents from the rural Northeast China were randomly selected and examined. MetS was defined according to the ATPIII-modified criteria. Data regarding the demographic and lifestyle characteristics and the blood biochemical indexes of these participants were collected by well-trained personnel. Results The prevalence of MetS was 39.0% and was more prevalent in women than in men (45.6% vs. 31.4%, P < 0.001). Elevated blood pressure was the most common metabolic disorder in both genders (71.7% in males and 63.3% in females). Only 11.2% and 9.6% of males and females, respectively, in this study had no metabolic disorders. Multivariate logistic regression, after adjusting for possible confounders, revealed the following factors that increased the risk of MetS: being female, older age, having more than one child, a family income of >20,000 CNY per year, longer sleep duration (>9 h/d), chronic disease status, frequent consumption of beans or bean products and frequent tea drinking. Completion of education through middle school, moderate physical activity and smoking were correlated with lower rates of MetS. Conclusion The prevalence of MetS was high in the rural areas of China, especially among females. In addition to some of the more conventional risk factors associated with MetS, including age, sex, annual income and educational status, we also found that having more than one child and frequent consumption of tea and beans were risk factors for MetS, while smoking was a common factor among those that did not have MetS in rural Northeast China.

Abstract
BACKGROUND Hypertension is a definitive risk factor for stroke. We examined the associations between hypertension subtypes and stroke incidence in rural Chinese adults. METHODS We conducted a prospective study in a sample of 38,949 rural Chinese adults aged ≥35 years and free from stroke at baseline. The subtypes of hypertension were defined as isolated systolic hypertension (ISH), isolated diastolic hypertension (IDH), systolic and diastolic hypertension (SDH), and managed hypertension (MHT). The relative risks of stroke with the subtypes of hypertension, compared with normotensive subjects, were estimated using the Cox model after adjusting for age, sex, and other confounders. RESULTS The prevalence of hypertension was as follows: SDH = 18.6%, ISH = 10.2%, IDH = 5.8%, and MHT = 0.4%. During a total of 168,023 person-years of follow-up, 858 subjects developed stroke. The incidence rate per 100,000 person-years of overall first-ever stroke was 510.6. The SDH group was at the highest risk of stroke among all the hypertensive subjects. The hazard ratio was 2.13 (95% confidence interval (CI) = 1.78-2.55) for all stroke, 2.74 (95% CI = 2.08-3.60) for hemorrhagic stroke, and 1.92 (95% CI = 1.50-2.45) for ischemic stroke. CONCLUSIONS SDH patients warrant the most attention for prevent of stroke. However, ISH and IDH are also independent predictors of stroke. The risk factors for stroke, especially hypertension, were not controlled in the rural population we studied. More aggressive efforts to control the risk factors for stroke in rural areas are needed.

Abstract
Although previous systematic reviews considered the relationship between socioeconomic status and obesity, almost 200 peer-reviewed articles have been published since the last review on that topic, and this paper focuses specifically on education, which has different implications. The authors systematically review the peer-reviewed literature from around the world considering the association between educational attainment and obesity. Databases from public health and medicine, education, psychology, economics, and other social sciences were searched, and articles published in English, French, Portuguese and Spanish were included. This paper includes 289 articles that report on 410 populations in 91 countries. The relationship between educational attainment and obesity was modified by both gender and the country's economic development level: an inverse association was more common in studies of higher-income countries and a positive association was more common in lower-income countries, with stronger social patterning among women. Relatively few studies reported on lower-income countries, controlled for a comprehensive set of potential confounding variables and/or attempted to assess causality through the use of quasi-experimental designs. Future research should address these gaps to understand if the relationship between educational attainment and obesity may be causal, thus supporting education policy as a tool for obesity prevention.

Abstract
BACKGROUND Obesity is one of the most common health problems in the world and is assuming epidemic proportions in both developed and developing countries. AIM The present study aimed to provide population-based data on the prevalence of obesity and estimation the risk of some of demographic factors associated with obesity. SUBJECTS AND METHODS From May 2007 through December 2008, we conducted a community-based cross-sectional survey on 3,000 males and females (age ≥ 20 years) in Tehran province. Respondents were asked to give their height and weight in the questionnaire. Body mass index (BMI) is recognized as the measure of overall obesity and calculated as body weight divided by the square body height in meters (kg/m(2)). RESULTS The overall prevalence of overweight and obesity was 34.1% (924/2708) and 15.4% (417/2708). The combined prevalence of both overweight and obesity was 51.2% (1387/2708) in males and 57.5% (1557/2708) in females. The mean (SD) BMI for the total population studied was 26.14 (4.71) and it was higher in women than in men (P < 0.001). The overall prevalence of overweight and obesity was 39.5% (376/952) and 11.7% (111/952) in men and 36.9% (548/1458) and 20.6% (306/1458) in women. The multivariate-adjusted odds ratios of obesity showed that higher ages, females, married and low educated subjects had more chance to being obese. CONCLUSION This population-based cross-sectional survey indicates that the prevalence of overweight and obesity are moderately high in the general Iranian population and must be considered as a significant public health problem at national level especially among women.

Abstract
Background The aim of this study was to describe the incidence, clinical sub-types, and associated risk factors of stroke among rural Chinese adults. Methods A population-based sample of 38 949 rural Chinese adults, aged ≥35 years and free from stroke at baseline, were followed from 2004–2006 to 2010. Stroke was defined by the World Health Organization diagnosis criteria. Results The age-standardized incidence rates per 100 000 person-years of overall, first ever stroke was 601·9 (95% confidence interval, 528·3 to 675·5), and mortality rate was 276·7 (95% confidence interval, 251·6 to 301·9). The age-standardized incidence rate was higher in men (775·9 per 100 000 person-years) than in women (435·6 per 100 000 person-years). Among 858 first ever stroke events, 56·3% were ischemic strokes, 40·6% were hemorrhagic strokes, and 3·1% were undetermined strokes. Hypertension and lipid disorder were common modifiable risk factors in the ischemic stroke and hemorrhagic stroke groups. Conclusions The annual incidence of stroke and resulting mortality has increased at an accelerated rate. Furthermore, the incidence of stroke in rural China was higher than that found in urban China and Western countries. Hypertension and lipid disorder were important modifiable risk factors. The primary sub-type of stroke observed in rural China was ischemic stroke. These findings underscored the need for more aggressive efforts to control the risk factors of stroke and other cardiovascular diseases in rural areas.

Abstract
BACKGROUND Obesity increases the risk of many diseases. However, there has been little literature about the epidemiology of obesity classified by body mass index (BMI) or waist (abdominal obesity) among urban Chinese adults. This study is to fill the gap by assessing the prevalence of obesity and associated risk factors among urban Chinese adults. METHODS A representative sample of 25,196 urban adults aged 18 to 74 years in Northeast China was selected and measurements of height, weight and waist circumference (WC) were taken from 2009-2010. Definitions of overweight and obesity by the World Health Organization (WHO) were used. RESULTS The overall prevalence rates of general obesity and overweight classified by BMI were 15.0% (15.7% for men and 14.3% for women, p<0.01) and 19.2% (20.8% for men and 17.7% for women, p<0.01), respectively, and the overall prevalence rate of abdominal obesity was 37.6% (31.1% for men and women 43.9% for women, p<0.01). Multivariable logistic regression showed that the elderly and those who had a history of parental obesity, alcohol drinking, or former cigarette smoking were at high risk of obesity classified by BMI or WC, whereas those with a higher level of education, higher family income, or a healthy and balanced diet were at low risk of obesity. Analysis stratified by gender showed that men with a higher level education level, a white-collar job, a cadre job, or higher family income were the high risk group, and women with a higher level of education or higher family income were the low risk group. CONCLUSIONS Obesity and overweight have become epidemic in urban populations in China; associations of risk factors with obesity differ between men and women.

Abstract
OBJECTIVE To determine the prevalence of and associated factors for overweight, especially to determine the relationship between the intake of monosodium glutamate (MSG) as a seasoning and overweight in Vietnam. DESIGN A cross-sectional survey was conducted of Vietnamese adults aged ≥20 years in 2008. Dietary intake was assessed by the 24 h recall method for 3 d. MSG intake was evaluated by the weighing method on three consecutive days. Physical activity was assessed based on the Global Physical Activity Questionnaire recommended by the WHO. Overweight was defined as BMI ≥ 23·0 kg/m2. Other characteristics such as age and lifelong occupation were determined by a structured questionnaire. SETTING Some rural and urban areas of Hanoi, Thua Thien Hue Province and Ho Chi Minh City, Vietnam. SUBJECTS A total of 1528 adults living in surveyed areas were randomly selected by the multistage cluster sampling method. RESULTS The prevalence of overweight was 27·9 %, and 81·0 % of participants were MSG users. Average MSG intake was 2·2 (sd 1·8) g/d. Multiple logistic regression analysis revealed that factors associated with overweight were age, region of residence, lifelong occupation, physical activity and intakes of energy, carbohydrates, saturated fat and animal protein. There was no significant association between MSG intake and overweight. CONCLUSIONS The study demonstrated that overweight was not associated with MSG intake in Vietnamese adults. Further longitudinal studies should be done in different populations to determine the relationship between MSG and overweight.

Abstract
OBJECTIVES To examine the effects of behavioral, health, and socio-demographic factors on being overweight or obese among older Chinese adults. METHODS This research uses panel data from the China Health and Nutrition Survey, which was designed to examine how social and economic transformation affected the health and nutritional status of residents. For these analyses, we used all available information on adults aged 60 years or older surveyed in 1997, 2000, 2004, and 2006 (N = 3,591). Body mass index (BMI) was dichotomized as normal (18.5-24.9 kg/m(2)) and overweight (25.0-29.9 kg/m(2))/obese (≥30 kg/m(2)). Generalized estimating equations were used to estimate population-averaged (marginal) effects. RESULTS The combined prevalence of overweight or obese was approximately 33%. Moderate or heavy non-leisure physical activities (OR = 0.39; 95% CI = 0.32-0.49) and smoking (OR = 0.69; 95% CI = 0.57-0.84) decreased the odds of being overweight or obese, while drinking alcohol (OR = 1.25; 95% CI = 1.05-1.50) increased the odds. For individuals in all income levels, the amount of non-leisure physical activity strongly affected the BMI among the older Chinese adults. CONCLUSIONS Active lifestyle interventions may help counter what could otherwise be a growing obesity epidemic in China.

Abstract
BACKGROUND Obesity is a disease condition that is highly prevalent in both developed and developing countries. Obesity accounts for 60% of cases of diabetes, 40% cases of hypertension and 20% of coronary heart disease and stroke. Although obesity is a silent killer in the third world countries, there is less focus on the problem, as the nations are still staggering with problems due to infectious and parasitic diseases. So, the current study was undertaken to highlight the problem. METHOD A cross-sectional community based survey, among individuals of either sex, aged 30 years and above was carried out on 1,239 respondents, using a two-stage stratified, random sampling technique. Data was collected by personal face to face interview using a pre-designed questionnaire and analyzed using Statistical Package for Social Sciences (SPSS) version 11.5. RESULTS The overweight category included 21.4% of the subjects. Obesity as per Body Mass Index (BMI) criteria was seen in 6.6% of the individuals but abdominal and truncal obesity was present among 51.7% and 62.1% respectively. Literacy up to secondary education and graduation were identified by the multivariate analysis to be associated with obesity. CONCLUSION The prevalence of central obesity was found to be high, and hence, lifestyle changes and improved physical activity needs promotion among the general population.

Abstract
The aim of the study was to determine the prevalence of overweight, obesity and abdominal obesity, and the underlying socio-demographic correlates among Sri Lankan adults. Data were from 4532 adults aged ≥18 years randomly selected for a national level study on diabetes and cardiovascular disease. Weight, height and waist circumference (WC) were measured and body mass index (BMI) calculated. The mean (95% confidence interval) BMI and WC were 21.1 kg m(-2) (20.9-21.3), 22.3 kg m(-2) (22.1-22.4) and 78.0 cm (77.5-78.6) and 77.5 cm (77.0-78.0) for males and females, respectively. According to the proposed World Health Organization cut-off values for Asians, the percentage of Sri Lankan adults in the overweight, obese and centrally obese categories were 25.2%, 9.2% and 26.2%, respectively. Based on the cut-offs for Caucasians, these were 16.8%, 3.7% and 10.8%. Our findings were compatible with prevalence of obesity in regional countries. In addition, female sex, urban living, higher education, higher income and being in the middle age were shown to be associated with overweight and obesity in Sri Lankans. In conclusion, we have documented a relatively high prevalence of overweight and obesity, particularly, abdominal obesity among adults in Sri Lanka which is a middle-income country. Urgent public health interventions are needed to control the problem at an early stage.

Abstract
BACKGROUND To determine the incidence of hypertension and its risk factors among rural Chinese women with prehypertension and normotension. METHODS A population-based sample of 12,060 rural Chinese women aged > or = 35 years and free from hypertension at baseline were followed from 2004-2006 to 2008. Incident hypertension was defined as systolic blood pressure (SBP) > or = 140 mm Hg, diastolic blood pressure (DBP) > or = 90 mm Hg, or current use of antihypertensive medication. RESULTS Over a median follow-up of 28 months (range, 14-47 months), 23.4% of women developed hypertension. The age-adjusted incidence rate was higher in prehypertension than in normotension (11.2/100 person-years vs. 7.9/100 person-years, P < 0.05). Among women with prehypertension, independent predictors of incident hypertension were baseline age, Mongolian ethnicity, low physical activity, baseline body mass index (BMI), baseline salt intake and family history of hypertension. Among women with normal blood pressure (BP), independent predictors were baseline age, low physical activity, baseline BMI and baseline salt intake. The awareness, treatment, and control rates for newly developed hypertension were 33.2, 23.0, and 2.1%, respectively. CONCLUSIONS These data indicate that the incidence of hypertension is high among rural Chinese women and it is associated with many risk factors, and the data also suggest that most newly developed hypertension cases are not treated. This high incidence of hypertension may be related to rapid social changes in our country and may apply to other areas of the developing world. These results call for urgent improvements in hypertension prevention, detection and treatment.

Abstract
UNLABELLED OBJECTIVE We wanted to determine the incidence of hypertension and its risk factors among rural Chinese adults. METHODS A population-based sample of 24,360 rural Chinese adults aged 35 years and older and free from hypertension at baseline was observed from 2004-2006 to 2008. Incident hypertension was defined as a systolic pressure of 140 mm Hg or greater, diastolic pressure of 90 mm Hg or greater, or current use of antihypertensive medication. RESULTS During a mean follow-up period of 28 months, 29.6% of men and 23.4% of women developed hypertension. The age-adjusted incidence was higher in men (12.75 per 100 person-years) than in women (10.04 per 100 person-years). Among men, independent predictors of incident hypertension were baseline age (hazard ratio [HR] = 1.11; 95% confidence interval [CI], 1.10-1.13), Mongolian ethnicity (HR = 1.09; 95% CI, 1.01-1.18), use of alcohol, (HR = 1.14; 95% CI, 1.06-1.23), high income vs low income (HR = 1.11; 95% CI, 1.00-1.22; and HR = 1.11; 95% CI, 1.03-1.20), prehypertension vs normotension (HR = 1.18; 95% CI, 1.08-1.28), overweight and obesity (HR = 1.28; 95% CI, 1.17-1.40), baseline salt intake (HR = 1.00; 95% CI, 1.00-1.01) and family history of hypertension (HR = 1.14; 95% CI, 1.03-1.27). With the exception of use of alcohol and mean income, the results were similar for women, except that low physical activity was shown as a risk factors as well. The awareness, treatment, and control rates for newly developed hypertension were 29.9%, 19.5%, and 1.5%, respectively. CONCLUSIONS These data indicate that the incidence of hypertension is high among these rural Chinese adults and that it is associated with many risk factors. Our findings further suggest that most newly developed hypertension cases are not treated. The increases in hypertension are probably related to rapid social changes in our country and may apply to other areas of the developing world. These findings call for urgent improvements in hypertension prevention and control programs in rural China.

Abstract
Obesity threatens developing countries as urbanization increases, with civil servants being particularly vulnerable. The authors assess overweight/obesity prevalence among Nepalese civil servants along with their knowledge and attitudes. A cross-sectional questionnaire survey conducted among 341 participants (97.4% response rate) also recorded height and weight. Participants were 40 ± 6.6 years, mostly males, married, and from a single ethnic group. Overweight/obesity prevalence was 33.4%. Knowledge of obesity was good. However, some attitudes toward obese people were negative, despite half of the participants believing obesity to indicate prosperity. Logistic regression indicated marriage and/or having a better job increased the overweight/obese risk by nearly 8 and 9 times, respectively. Heavier people were more likely to disagree with attitudes that obese people were "lazier" and "untidy." Obesity prevalence among Nepalese civil servants is already higher than the general population level. Health education and interventions are needed to translate knowledge into attitude and behavior changes in order to prevent this becoming an epidemic.

[PMID: 19328637 DOI: 10.1016/j.maturitas.2009.02.010] [Citation(s) in RCA: 59] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2009] [Revised: 02/18/2009] [Accepted: 02/23/2009] [Indexed: 02/06/2023]
Abstract
OBJECTIVES Obesity is currently a major public health concern; however, there is little data available on the prevalence and impact of obesity within the elderly population. This review examines the prevalence and health effects of obesity among individuals aged > or =50. METHODS PubMed (1996-2008) and PsychInfo (2002-2008) search engines were used to retrieve qualified peer-reviewed articles focusing on obesity or a health condition correlated with obesity using BMI or other weight index as a defining variable; and studies limited to the elderly (age 60+) or pre-elderly (50+). RESULTS Worldwide, the elderly population is increasingly becoming obese regardless of socio-economic status. Among elderly persons, obesity increases the risks for a variety of morbidity conditions including cancers, diabetes, hypertension, stroke, heart disease, metabolic syndrome, obstructive sleep apnea syndrome, osteoarthritis, depression, disability, and lower scores on quality of life measures. In some reports, obesity has been linked to Alzheimer's disease and other forms of cognitive decline. Obesity significantly increases healthcare costs and nursing homes are currently ill equipped to address the needs of the rising number of obese residents. CONCLUSIONS Obesity is increasing in the elderly population worldwide and is expected to continue to rise. Obesity is associated with disease and disability in addition to escalating healthcare costs, and hospitals and nursing homes are ill equipped to serve the obese elderly. It is imperative that research efforts and funding be devoted to studying the effects and the reduction of obesity in the elderly population.

Abstract
The relationship between body mass (usually measured as BMI in kg/m(2)) and healthy longevity is a major focus of study in the nutrition and aging field. Over-nutrition now rivals frailty as the major nutritional concern; the number of older adults who are obese has increased dramatically in the past 3 decades. While obesity exacerbates a host of life-threatening, age-related chronic diseases, a somewhat paradoxical finding is that being somewhat overweight in old age appears to be a benefit with regard to longevity. In our recently completed systematic review of randomized controlled weight reduction trials, we found that weight loss interventions in overweight/obese older subjects led to significant benefits for those with osteoarthritis, coronary heart disease, and type 2 diabetes mellitus, while having slightly negative effects on bone mineral density and lean body mass. In contrast to this finding, the preponderance of epidemiological evidence indicates that higher BMIs are associated with increased survival after age 65 years. Because of this contradictory state of the science, there is a critical need for further study of the relationship of weight and weight loss/gain to health in the later years of life.
