目的 调查广东省顺德市容奇镇肥胖症及其相关疾病的流行病学情况 ,并分析体重指数 (BMI)、腰围及腰臀比与高血压的关系。方法 普查容奇镇 15岁以上所有有户口的居民 2 5 6 80人 ,内容包括问卷 ,测定身高、体重、血压 ,对于≥ 4 0岁的被调查者还测定了腰围、臀围等。结果1996年容奇镇 15岁以上的人群中 ,BMI 2 3.0～ 2 4 .9kg/m2 占 13.4 % (标化率 ,以下同 ) ,2 5 .0～ 2 9.9kg/m2 占 8.9% ,≥ 30kg/m2 占 1.3%。随年龄增加 ,肥胖患病率增高 ,5 0～ 5 9岁组最高。 4 0岁以上的人群中 ,腹型肥胖患病率为 35 .0 % (以腰围为判断标准 )和 36 .7% (以腰臀比为判断标准 )。女性腹型肥胖患病率明显高于男性。高血压患者中更倾向于腹型肥胖。以高血压为状态变量 ,以BMI、腰围、腰臀比为测定变量 ,做受试者工作特征曲线 (ROC曲线 ) ,并对曲线下面积两两比较 ,结果提示腰围、腰臀比对高血压诊断的特异性和敏感性明显优于BMI;腰围、腰臀比对高血压诊断的特异性和敏感性差异无显著性。结论 ≥ 4 0岁以上人群中腹型肥胖患病率较高 ,且女性高于男性。腰围、腰臀比对高血压诊断的特异性和敏感性明显优于BMI
Objective To investigate the prevalence of obesity and its related diseases in Rongqi Town, Shunde City, Guangdong Province, and to analyze the relationship between body mass index (BMI), waist circumference, waist-hip ratio and hypertension. Methods Census of all over the age of 15 in the town of Citizens of more than 25,680 people, including questionnaires, height, weight, blood pressure, for ≥ 40 years of age the respondents also measured waist circumference, hip circumference and so on. Results In 1996, the population aged 15 and over in Rongqi Town was 13.4% BMI 2 3.0-2.49kg / m2 (standardization rate, the same below), 8.9% of 25.0-2.9.9kg / m2, ≥ 30kg / m2 accounted for 1.3%. With age, the prevalence of obesity increased, the highest in the group of 50 to 59 years old. The prevalence of abdominal obesity was 35.0% (based on the waist circumference) and 36.7% (waist to hip ratio were the criteria) for people over 40 years of age. The prevalence of abdominal obesity in women was significantly higher than that in men. Hypertensive patients are more inclined to abdominal obesity. Hypertension as a state variable, BMI, waist circumference, waist-to-hip ratio were measured variables to do the work of the receiver operating characteristic curve (ROC curve), and the area under the curve of each comparison, the results suggest that waist circumference, waist-hip ratio of hypertension The diagnostic specificity and sensitivity were significantly better than those of BMI. There was no significant difference in the specificity and sensitivity of waist circumference and waist-hip ratio in the diagnosis of hypertension. Conclusion The prevalence of abdominal obesity in people over 40 years old is higher than that of men. Waist circumference, waist-hip ratio of hypertension diagnosis of specificity and sensitivity was significantly better than the BMI
