居民职业和劳动强度对肥胖及高血压患病的影响

目的了解南京市居民肥胖、高血压患病率情况以及分析居民职业、劳动强度等因素对肥胖、高血压患病率的影响。方法选择南京市1个农村地区，1个郊区及城区，共随机抽取18周岁以上居民1983名作为调查对象，内容包括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，居民高血压患病率与年龄、职业、文化程度、劳动强度及每周劳动时间有关（P〈0．05）；居民肥胖率和性别、职业、劳动强度及每周劳动时间有关（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。

Influence of occupation and labor intensity on prevalence rates of obesity and hypertension in residents

[ Objective] To know the prevalence rates of obesity and hypertension among residents in Nanjing City, analyze the influence of occupation and labor intensity on prevalence rates of obesity and hypertension. [ Methods] 1 983 residents above 18 years old were randomly collected from 1 rural area, and 1 suburb and urban area in Nanjing City, and the survey contents included questionnaire investigation and physical examination. [ Results ] The prevalence rate of obesity and hypertension was 14.3 % and 33.6% respectively. The univariate logistic regression analysis showed that the prevalence rate of hypertension was related to age, occupa- tion, educational level, labor intensity and working hours per week I P 〈 0.05 }, while the prevalence rate of obesity was related to gender, occupation, labor intensity and working hours per week （P 〈 0. 051. The multivariate logistic regression analysis revealed that the increase of age was the risk factor of hypertension, and female was the risk factor of obesity. [ Conclusion]The urban-rural gap in prevalence rates of obesity and hypertension has decreased obviously. The age is the influencing factor of hypertension, and gender is the influencing factor of obesity.
