目的了解南京市居民体力活动状况和肥胖、高血压患病率情况以及分析身体活动等因素对肥胖、高血压患病率的影响。方法在南京市各选1个城区、郊区及农村地区共随机抽取1 983名18周岁以上居民作为调查对象,进行问卷调查和体格检查。结果调查对象肥胖率为14.3%,高血压患病率为33.6%。单因素logistic回归分析结果表明,居民高血压患病率和年龄、职业及家务劳动时间有关(P<0.05);居民肥胖率和性别及职业有关(P<0.05)。多因素logistic回归分析结果表明,年龄增高是高血压患病的危险因素,女性是肥胖的危险因素。结论南京市居民体力活动不足,尤其是年轻在职(及农民)人员自主锻炼意识较低;肥胖及高血压患病率城乡差距明显缩小。年龄是高血压患病的影响因素;性别是肥胖的影响因素。
Objective To understand the physical activity status of Nanjing residents and the prevalence of obesity and hypertension as well as the impact of physical activity and other factors on the prevalence of obesity and hypertension. Methods A total of 1 983 residents over the age of 18 years were selected randomly from 1 urban, suburban and rural areas in Nanjing as subjects for questionnaire survey and physical examination. Results The obesity rate was 14.3% and the prevalence of hypertension was 33.6%. The results of univariate logistic regression analysis showed that the prevalence of hypertension was related to age, occupation and housework time (P <0.05). The obesity rate of residents was related to sex and occupation (P <0.05). Multivariate logistic regression analysis showed that age is a risk factor for hypertension, and women are risk factors for obesity. Conclusion Nanjing residents lack of physical activity, especially young working (and peasants) have a lower awareness of independent exercise; the prevalence of obesity and hypertension significantly narrowed the gap between urban and rural areas. Age is the influencing factor of hypertension; sex is the influencing factor of obesity.
