Overweight Japanese with body mass indexes of 23.0-24.9 have higher risks for obesity-associated disorders: a comparison of Japanese and Mongolians

OBJECTIVE: The degree of obesity of Asians is less than that of Caucasians. It has been suggested that Japanese, categorized as having normal weight (BMI<25.0), as defined by WHO (2000), have a tendency toward increased incidences of dyslipidemia and diabetes. Our objective was to analyze parameters constituting obesity-associated disorders in overweight Japanese and Mongolians with a body mass index (BMI) of 23.0-24.9, and to assess the suitability for Asians of the Regional Office for Western Pacific Region of WHO criteria pertaining to obesity (WPRO criteria, 2000). DESIGN: Cross-sectional study in a workplace setting. SUBJECTS: A total of 386 Japanese men and 363 Japanese women, and 102 Mongolian men and 155 Mongolian women. MEASUREMENTS: Anthropometric measurements (weight, height, waist circumference, hip circumference and blood pressure) and metabolic measurements (plasma levels of total cholesterol, HDL cholesterol, triglyceride, glucose and insulin). RESULTS: Graded increases in BMI of Japanese and Mongolians were positively associated with body fat percent, waist circumference, hip circumference and waist/hip ratio. The Japanese were categorized as 22% overweight, 22% obese I, 3% obese II; the Mongolians rated as 18% overweight, 34% obese I, 19% obese II, based on the WPRO BMI criteria. The Mongolians had a higher prevalence of obesity and a higher body fat percent, but a lesser gradation of dyslipidemia, than did the BMI-matched Japanese groups. Overweight Japanese (BMI 23.0-24.9), in comparison to normal Japanese (BMI 18.5-22.9), had significant differences in systolic blood pressure, HDL-cholesterol and triglyceride in men, and in systolic and diastolic blood pressure, HDL-cholesterol, triglyceride, insulin and Homoeostasis model assessment-insulin resistance in women. In contrast, the Mongolians showed no significant differences in metabolic parameters between overweight and normal subjects, except for diastolic blood pressure. CONCLUSION: Since the relationship between abdominal fat mass and BMI is ethnic-specific, a universal BMI cutoff point is inappropriate for Asian populations such as the Japanese and Mongolians. The present investigation suggests that, while the WPRO criteria are suitable for Japanese, the WHO criteria are more appropriate for Mongolians.     

National Cholesterol Education Program Adult Treatment Panel III guidelines and obesity: implications for Canada

BACKGROUND: The National Cholesterol Education Program Adult Treatment Panel (ATP) III recommendations incorporate new evidence for treating elevated low-density lipoprotein cholesterol. OBJECTIVES: Comparisons between the prevalence of drug-eligible Canadians under the old ATP II and the new ATP III guidelines were made, and the impact of obesity on current and future drug eligibility was explored using various models. METHODS: Participants from the Canadian Heart Health Surveys (1986 to 1992; n=17,728; 20 to 74 years of age) were assigned to therapeutic lifestyle change or drug-eligible groups in the event of elevated low-density lipoprotein cholesterol. Body mass index was used to classify participants as having normal weight, or as being overweight or obese. The prevalence of overweight and obese status for 2001, 2006 and 2011 were projected from past trends by linear regression. Population attributable risk was used to model reductions or increases in the prevalence of obesity in drug-eligible participants using several nationally representative population health surveys. RESULTS: In 2001, an additional 1.1 million Canadians were drug-eligible under ATP III (16.0% of men, 9.5% of women), compared with ATP II (7.7% of men, 7.7% of women). Drug eligibility was elevated in overweight participants (men: OR=1.87 [1.51 to 2.31]; women: OR=1.60 [1.13 to 2.28]) and the obese (men: OR=2.86 [1.86 to 4.38]; women: OR=2.28 [1.63 to 3.18]) versus normal weight participants. The population attributable risk was higher in men (overweight 22.6%, obese 11.5%) than in women (overweight 9.4%, obese 9.2%). IMPLICATIONS: A 10% reduction in overweight and obesity prevalence could have prevented 69,530 cases of drug eligibility in 2001. On the other hand, by 2011 over one million Canadians will be drug-eligible because of an elevated body mass index, if the recent trends in overweight and obese status continue.     

Body mass index,waist circumference,and health risk: evidence in support of current National Institutes of Health guidelines

BACKGROUND: No evidence supports the waist circumference (WC) cutoff points recommended by the National Institutes of Health to identify subjects at increased health risk within the various body mass index (BMI; calculated as weight in kilograms divided by the square of height in meters) categories. OBJECTIVE: To examine whether the prevalence of hypertension, type 2 diabetes mellitus, dyslipidemia, and the metabolic syndrome is greater in individuals with high compared with normal WC values within the same BMI category. METHODS: The subjects consisted of 14 924 adult participants of the Third National Health and Nutrition Examination Survey, which is a nationally representative cross-sectional survey. Subjects were grouped by BMI and WC in accordance with the National Institutes of Health cutoff points. Within the normal-weight (18.5-24.9), overweight (25.0-29.9), and class I obese (30.0-34.9) BMI categories, we computed odds ratios for hypertension, diabetes, dyslipidemia, and the metabolic syndrome and compared subjects in the high-risk (men, >102 cm; women, >88 cm) and normal-risk (men, 相似文献   

Prevalence of overweight and obesity in Turkey

The objectives of this study were to determine the prevalence of overweight and obesity in Turkey, and to investigate their association with age, gender, and blood pressure. A crosssectional population-based study was performed. A total of 20,119 inhabitants (4975 women and 15,144 men, age > 20 years) from 11 Anatolian cities in four geographic regions were screened for body weight, height, and systolic and diastolic blood pressure between the years 1999 and 2000. The overall prevalence rate of overweight was 25.0% and of obesity was 19.4%. The prevalence of overweight among women was 24.3% and obesity 24.6%; 25.9% of men were overweight, and 14.4% were obese. Mean body mass index (BMI) of the studied population was 27.59 +/- 4.61 kg/m(2). Mean systolic and diastolic blood pressure for women were 131.0 +/- 41.0 and 80.2 +/- 16.3 mm Hg, and for men 135.0 +/- 27.3 and 83.2 +/- 16.0 mm Hg. There was a positive linear correlation between BMI and blood pressure, and between age and blood pressure in men and women. Obesity and overweight are highly prevalant in Turkey, and they constitute independent risk factors for hypertension.     

Assessing obesity and overweight in a high mountain Pakistani population

OBJECTIVES: To estimate the prevalence of obesity and overweight among adults in a high mountain rural population of Pakistan, and to determine the correlates of excess body weight. Design Cross-sectional study. METHODS: A random sample of 4203 adults (aged 18 years and over) was selected by stratified random sampling from 16 villages in north Pakistan. Trained medical students measured height, weight and blood pressure. Trained interviewers obtained information from participants on sociodemographic variables, use of snuff, daily cigarette consumption, hypertension and family history of hypertension. Body mass index (BMI) calculated as kg/m(2) was used to define overweight (BMI > or = 25 kg/m(2)) and obesity (BMI > or = 30 kg/m(2)). RESULTS: Using weight and height data available for 1391 men and 2754 women, mean BMI was 22.4 (95% CI 21.9, 22.9) for men and 22.6 (95% CI 21.9, 23.2) for women. The age-adjusted prevalence of BMI > or = 25 (overweight/obesity) was 13.5% for men and 14.1% for women. Overweight/obesity increased with age and the increase per year was identical for both men and women [adjusted odds ratio (AOR) = 1.01, 95% CI 1.01, 1.03]. Overweight/obese men and women were more likely to be hypertensive (men, AOR = 3.32, 95% CI 2.16, 5.09; women, AOR = 1.70, 95% CI 1.21, 2.39). Overweight/obese women were more likely to work in business or as skilled workers (AOR = 6.24, 95% CI 1.18, 32.83) while overweight/obese men were more likely to work as government employees (AOR = 2.59, 95% CI 1.66, 4.03). Family history of hypertension was a significant correlate of overweight/obesity in men (P value 0.004) and women (P value 0.000). Overweight/obese men and women were less likely to use smokeless tobacco (men, AOR = 0.65, 95% CI 0.43, 0.97; women, AOR = 0.54, 95% CI 0.35, 0.85). CONCLUSION: The prevalence of risk factors for non-communicable diseases (NCDs) in Pakistan is expected to increase as further epidemiologic, nutritional and demographic changes occur. The assessment of excess body weight, and patterns and determinants of other risk factors for NCDs is important to provide useful guidelines in the planning of interventions to counter a growing problem.     

Milk intake is inversely related to obesity in men and in young women: data from the Portuguese Health Interview Survey 1998-1999

OBJECTIVE: To assess the relationships between milk intake and body mass index (BMI) in a representative sample of the mainland Portuguese population. DESIGN: Cross-sectional study. SETTING: National Health Interview Survey 1998-1999. Average daily milk intake was calculated by a frequency questionnaire that also assessed the average volume of one serving. BMI was derived from the subject's reported height and weight. SUBJECTS: A total of 17,771 men and 19 742 women aged > or =18 y. RESULTS: In men, milk intake was inversely related to BMI (r = -0.10, P < 0.001), whereas the relationship in women was weaker (r = -0.06, P < 0.001). In men, prevalence of milk consumers was lower in obese (62%) and in overweight (68%) than in normal weight subjects (71%, P < 0.001). After adjusting for age, region, physical activity, smoking, number of meals and educational level, milk intake decreased with increasing BMI (adjusted mean +/- s.e.: 280 +/- 5, 266 +/- 5 and 246 +/- 7 ml/day for normal, overweight and obese subjects, respectively, P < 0.001), even after excluding subjects who did not consume milk (368 +/- 5, 353 +/- 6 and 346 +/- 8 ml/day, P < 0.02). In women, prevalence of milk consumers was lower in obese (71%) and in overweight (72%) than in normal weight subjects (76%, P < 0.001). In women younger than 55 y, milk intake decreased with increased BMI categories (291 +/- 9, 271 +/- 10 and 269 +/- 11 ml/day for normal, overweight and obese subjects, respectively, P < 0.001), whereas no relationship was found in the older group. CONCLUSIONS: Increased calcium intake is slightly but significantly negatively related with BMI in men and premenopausal women. The lack of relationship in older women might be due to the hormonal status, but awaits further investigation.     

Body mass index in a US national sample of Asian Americans: effects of nativity, years since immigration and socioeconomic status

OBJECTIVE: To examine body mass index (BMI) and the proportion overweight and obese among adults age 18-59 in the six largest Asian American ethnic groups (Chinese, Filipino, Asian Indian, Japanese, Korean, Vietnamese), and investigate whether BMI varies by nativity (foreign-vs native-born), years in US, or socioeconomic status. DESIGN: Cross-sectional interview data were pooled from the 1992-1995 National Health Interview Survey (NHIS). SUBJECTS: 254,153 persons aged 18-59 included in the 1992-1995 NHIS. Sample sizes range from 816 to 1940 for each of six Asian American ethnic groups. MEASUREMENTS: Self-reported height and weight used to calculate BMI and classify individuals as overweight (BMI > or = 25 kg/m2) or obese (BMI > or = 30 kg/m2), age, sex, years in the US, household income and household size. RESULTS: For men, the percentage overweight ranges from 17% of Vietnamese to 42% of Japanese, while the total male population is 57% overweight. For women, the percentage overweight ranges from 9% of Vietnamese and Chinese to 25% of Asian Indians, while the total female population is 38% overweight. The percentage of Asian Americans classified as obese is very low. Adjusted for age and ethnicity, the odds ratio for obese is 3.5 for women and 4.0 for men for US-vs foreign-born. Among the foreign-born, more years in the US is associated with higher risk of being overweight or obese. The association between household income for women is similar for US-born Asian Americans and Whites and Blacks, but is much weaker for foreign-born Asian Americans. CONCLUSIONS: While these data find low proportions of Asian Americans overweight at present, they also imply the proportion will increase with more US-born Asian Americans and longer duration in the US.     

Prevalence of paradoxically normal serum cholestrol in morbidly obese women

The paradox that cholesterol may be lower in extremely obese subjects versus those who are less overweight, although originally observed more than 40 years ago, has never been documented in a systematic fashion. We have therefore prospectively determined the body mass index (BMI) and serum cholesterol concentration in 3,312 women. The percentage of women with serum cholesterol in the normal range (<200 mg/dL) decreased with an increasing BMI, from 55% in women with a BMI less than 20 kg/m2 to 28% in those with a BMI of 30 to 35 kg/m2. Serum cholesterol greater than 300 mg/dL was found in only 2% of individuals with a BMI less than 20 kg/m2 but in 6% of the group with a BMI between 30 and 35 kg/m2. However, among morbidly obese women (BMI >40 kg/m2, n = 46), 39% presented with serum cholesterol less than 200 mg/dL and only one woman had serum cholesterol more than 300 mg/dL. With the BMI, the fitted regression model shows an increase in cholesterol for low BMIs, while cholesterol appears to decrease with larger values for the BMI. The age-dependent increase in cholesterol is more evident in younger women versus older women, where it tends to disappear. It is concluded that among morbidly obese women (BMI >40 kg/m2), there is a substantial subgroup with normal serum cholesterol.
