浙江省居民体质指数与相关疾病关系

目的 探讨浙江省居民中体质指数(BMI)的分布特征及其与主要相关疾病的关系。方法 2006年1月,采用多阶段分层整群抽样方法随机抽取浙江省30个县(市、区),150个乡镇(街道),9000个住户中的居民为调查对象。通过自制问卷实施入户调查及体测。结果 共收集有效问卷23128份。样本人群BMI均值为(23.11±2.71),超重和肥胖率分别为28.7%和4.8%;城市居民的超重和肥胖率高于农村居民;男性的超重比例高于女性,肥胖比例低于女性;15岁~年龄组超重和肥胖率最低,随着年龄的增长,超重和肥胖率都呈上升趋势,45岁~组超重率最高(38.7%),55岁~组肥胖率最高(8.1%);已婚组的超重和肥胖率都高于未婚组,与离婚组无明显差异;随着文化程度的升高男性超重率升高,而肥胖率无明显差异;随着文化程度的升高女性超重和肥胖率都呈下降趋势;超重组和肥胖组的高血压、糖尿病和胆囊炎患病率均显著高于正常组,肥胖组冠心病患病率显著高于正常组。结论 近几年,浙江省居民超重率呈上升趋势,BMI与高血压等慢性病患病率呈正相关。

Study on body mass index and its relationship with chronic diseases of Zhejiang residents

Objective To analyse distributing character istic of body mass index(BMI)and its relationship with diseases of Zhejiang adults.Methods Stratified multi-stage cluster randomization was used to identify 30 counties(cities),150 to wnships(urban districts)and 9000 households.All family adults were surveyed by using self-regulating questionnaire and measured at their home.Results 23 128 respondents were valid.The average value of BMI was(23.11±2.71)among the respondents,the ratio of overweight and obesity were 28.7% and 4.8%,respectively.The ratio of overweight and obesity of urban adults were higher than that of rural ones.The ratio of overweight of male was significantly higher than that of female,while the ratio of obesity of male was lower than that of female.The ratio of over weight and obesity of the group 15~year old was the lowest and incr easing with the growing of age.The ratio of overweight of the group 45~year old was the highest (38.7%),while the ratio of obesity of the group 55~year old was the highest(8.1%).The ratio of over weight and obesity of the group of the married were higher than that of the group of unmarried and was no significant difference with the group of the divorced.The ratio of over weight of male was raising along with the growing of education level,while the ratio of obesity was no significant difference.The ratio of overweight and obesity of female were declining along with the growing of education level.The prevalence of hypertension,diabetes and cholecystit is in the group of overweight and obesity were significant higher than that of the group of normal,while the prevalence of coronary heart disease in the group of obesity was significantly higher than that of the group of normal.Conclusion The ratio of overweight of Zhejiang adults was growing in these years.The prevalence of chronic diseases such as hyper tension was increasing with BMI.
