目的了解山西省神池县城乡居民超重和肥胖患病现况及危险因素,为制定相应的干预措施提供科学依据。方法采取分层整群抽样方法,抽取神池县龙泉、义井、八角、贺职4个乡镇,每个乡镇随机抽取2个居委会(村)作为调查点,对每个调查点20~74岁常住居民进行超重和肥胖的现况及相关危险因素调查。结果共有效调查2231人,其中男性871人,女性1360人,超重率为28.6%(标化率为26.7%),肥胖率为5.1%(标化率为4.5%)。男女性间超重率差别有统计学意义(X2=4.595,P〈0.05),肥胖率差别无统计学意义(X2=2.181,P〉0.05)。经多元逐步回归分析发现,年龄、文化程度、家庭年收入、饮酒、运动情况、饮食控制情况和家族史等与体质指数有相关性,其中运动情况和饮食控制情况与体质指数呈负相关。结论山西省神池县居民超重和肥胖率较高,应针对超重和肥胖患病现状及其相关因素采取综合性预防措施,以降低其患病率及其相关疾病的患病率。
