OBJECTIVE: To evaluate the impact of generalized, abdominal, and truncal fat deposits on the risk of hypertension and/or diabetes and to determine whether ethnic differences in these fat patterns are independently associated with increased risk for the hypertension-diabetes comorbidity (HDC). RESEARCH METHODS AND PROCEDURES: Data (n = 7075) from the Third U.S. National Health and Nutrition Examination Survey were used for this investigation. To assess risks of hypertension and/or diabetes that were due to different fat patterns, odds ratios of men and women with various cut-points of adiposities were compared with normal subjects in logistic regression models, adjusting for age, smoking, and alcohol intake. To evaluate the contribution of ethnic differences in obesity to the risks of HDC, we compared blacks and Hispanics with whites. RESULTS: Generalized and abdominal obesities were independently associated with increased risk of hypertension, diabetes and HDC in white, black, and Hispanic men and women. The risk of HDC due to generalized, truncal, and abdominal obesities tended to be higher in whites than blacks and Hispanics. In men, the contribution of black and Hispanic ethnicities to the increased risk of HDC due to the various obesity phenotypes was approximately 73% and approximately 61%, respectively. The corresponding values for black and Hispanic women were approximately 115% and approximately 125%, respectively. CONCLUSIONS: In addition to advocating behavioral lifestyles to curb the epidemic of obesity among at-risk populations in the United States, there is also the need for primary health care practitioners to craft their advice to the degree and type of obesity in these at-risk groups. 相似文献

Objective : To compare a simple measure ‐ age of onset of obesity ‐ to an obese‐years construct (a product of duration and magnitude of obesity) as risk factors for type 2 diabetes. Method : Participants from the Framingham Heart Study who were not obese and did not have diabetes at baseline were included (n=4,320). The Akaike Information Criterion (AIC) was computed to compare four Cox proportional hazards models with incident diabetes as the outcome and: (i) obese‐years; (ii) age of onset of obesity; (iii) body mass index (BMI); and (iv) age of onset of obesity plus magnitude of BMI combined, as exposures. Results : AIC indicated that the model with obese‐years provided a more effective explanation of incidence of type 2 diabetes compared to the remaining three models. Models including age of onset of obesity plus BMI were not appreciably different from the model with BMI alone, except in those aged ≥60. Conclusions : While obese‐years was the optimal obesity construct to explain risk of type 2 diabetes, age of onset may be a useful, practical addition to current BMI in the elderly. Implications : Where computation of obese‐years is not possible or impractical, age of onset of obesity combined with BMI may provide a useful alternative. 相似文献

For examination of sex- and age-specific relations between smoking and risk of type 2 diabetes mellitus, 39,528 nondiabetic men and 88,613 nondiabetic women aged 40-79 years who underwent health checkups in Ibaraki-ken, Japan, in 1993 were followed through 2002. Risk ratios for diabetes according to smoking habits were calculated using a Cox proportional hazards model. Compared with never smokers, the risk ratio for diabetes among current smokers, after adjustment for age, systolic blood pressure, antihypertensive mediation use, alcohol intake, parental history of diabetes, body mass index, fasting status, blood glucose concentration, total and high density lipoprotein cholesterol levels, and log-transformed triglyceride level, was 1.27 (95% confidence interval (CI): 1.16, 1.38) in men and 1.39 (95% CI: 1.20, 1.61) in women. The excess risk was more pronounced among men with a parental history of diabetes than among men without one. The excess risk among current smokers was observed in both age subgroups (40-59 and 60-79 years). Respective multivariate risk ratios for the age subgroups were 1.37 (95% CI: 1.18, 1.60) and 1.20 (95% CI: 1.08, 1.34) in men and 1.45 (95% CI: 1.18, 1.79) and 1.34 (95% CI: 1.09, 1.66) in women. Smoking was independently associated with increased risk of type 2 diabetes among both middle-aged and elderly men and women. 相似文献

The relationship of body mass index (BMI), conicity index (CI) and waist circumference to four coronary heart disease (CHD) risk factors (systolic and diastolic blood pressures, total cholesterol and high-density lipoprotein (HDL) cholesterol levels) was examined in urban (n = 110) and rural (n = 102) men aged > or = 20 years, drawn from the 'Reddy' population of Southern Andhra Pradesh, India. Using ANCOVA we found significant difference (< 0.01) for systolic blood pressure, total cholesterol and HDL cholesterol between the urban and rural samples. The Pearson's correlation coefficients suggest that BMI and waist circumference had significant relationships with most of the risk factors in both the populations. The CI did not significantly influence any of the risk factors in the urban population; however, in the rural population, CI did show a significant positive relationship with both of the blood pressures and with TC. Even after controlling for age, smoking and physical activity (partial correlations), the relations remained constant. In multiple linear regression, BMI showed significant positive association with systolic and diastolic blood pressures (<0.01) and HDL cholesterol (<0.05) in the rural population only. However, the Cl showed a significant association with HDL cholesterol, and waist circumference with total cholesterol and HDL cholesterol in the rural population. The results of the present study revealed that BMI and waist circumference had a greater influence on the CHD risk factors, and that the influence was more conspicuous in the rural sample. Comparing the association of abdominal obesity measures (CI and waist circumference) with CHD risk factors, waist circumference better correlated with most of the risk factors. Hence the present study suggests that BMI and waist circumference are better indicators of CHD risk factors. However, the importance of Cl has to be further studied in South Asian populations. 相似文献

Previously reported associations between abdominal adiposity and coronary heart disease (CHD) may be mediated through serum lipids. In the present longitudinal study, 43 Western Samoan men who participated in a 1982 study were recontacted for a second determination of anthropometric and serum lipoprotein cholesterol levels. The men showed dramatic increases in weight (mean change ± SD: 10.5 ± 8.8 kg), abdominal circumference (10.0 ± 7.6 cm), total cholesterol (49.5 ± 26.4 mg/dl), and non-HDL cholesterol (53.1 ± 26.6 mg/dl). A new indicator was used to estimate changes in abdominal adiposity: the residual from the regression of change in the abdominal circumference on change in body weight (the AR). The AR was significantly correlated with changes in total (r = 0.38) and non-HDL cholesterol (r = 0.39). Changes in HDL cholesterol were correlated with changes in weight only (r = −0.37). These bivariate relations remained significant in multiple linear regression analyses. These longitudinal results are the first to suggest changes in abdominal adiposity are related to changes in total and non-HDL cholesterol levels. 相似文献

Migration and its impact on adiposity and type 2 diabetes 总被引:2,自引:1,他引:1
In this review, we discuss the impact of migration on the incidence and prevalence of obesity and type 2 diabetes mellitus (T2DM) in different ethnic groups and populations. We also analyze the determinants of such phenomena in view of the global increase in the migration and escalating prevalence of obesity and T2DM. The risk escalation of the obesity and T2DM followed a gradient, as migrants (Blacks, Hispanics, Chinese, South Asians, etc.) became more affluent and urbanized, indicating an important role of environmental factors. A stepwise increase in the prevalence of obesity in Blacks along the path of migration (5% in Nigeria, 23% in Jamaica, and 39% in the United States) is a classic example. Furthermore, South Asian migrants, who are particularly predisposed to develop insulin resistance and T2DM, showed nearly four times prevalence rates of T2DM than rural sedentee populations. Similar observations were also reported in intracountry migrants and resettled indigenous populations. The determinants were found to include nutrition transition, physical inactivity, gene-environment interaction, stress, and other factors such as ethnic susceptibility. However, certain contradictory trends were also seen in some migrant communities and have been explained by various phenomena such as healthy migrant effect, "salmon bias", and adherence to traditional diets. A review of the evidence suggests a critical role of environmental factors in conferring an increased risk of obesity and T2DM. The important contributory factors to this phenomenon were urbanization, mechanization, and changes in nutrition and lifestyle behaviors, but the role of stress and as yet unknown factors remain to be determined. 相似文献
