云南罗平县农村居民心血管病危险因素聚集性分析

Relationship between prevalence of cardiovascular diseases and clustering of risk factors among rural residents in Luoping county of Yunnan province

目的分析云南省罗平县农村心血管疾病患病与危险因素聚集性的关系。方法采用按比例概率抽样法,选取罗平县12个乡镇≥18岁常住农村居民4801人,进行现场问卷调查和现场体检,分析比较高血压、脑卒中和心脏病患病率与心血管病危险因素聚集程度的关系。结果罗平县农村居民吸烟、饮酒、超重、肥胖、糖尿病、中心性肥胖、高血脂、高盐饮食和心血管病家族史检出率分别为31.1%、20.9%、25.1%、7.0%、6.8%、43.8%、0.6%、15.9%和6.1%;女性肥胖率、中心性肥胖率和糖尿病检出率均高于男性(P<0.05);男性具有2个以上危险因素的聚集程度明显高于女性;高血压、脑卒中和心脏病的患病率分别为17.1%、0.7%和0.5%;随着心血管病危险因素聚集程度增加,高血压和脑卒中患病率也随之升高(P<0.01)。结论心血管疾病危险因素在农村居民中分布广泛,降低心血管危险因素聚集度有助于降低高血压和脑卒中的患病率。

Objective To examine the relationship between prevalence of cardiovascular diseases（CVD） and clustering of risk factors among rural residents in Luoping conty of Yunnan province.Methods Probability proportional to size（PPS） sampling method was used to select a representative sample of 4 801 residents aged 18 years and over from Luoping county.A questionnaire survey and physical examination were conducted among the residents.Results The prevalences of hypertension,stroke,heart disease,smoking,drinking,overweight,obesity,diabtets,central obesity,high serum total cholesterol,heavy salty food intake,and family history of CVD were 17.1%,0.7%,0.5%,31.1%,20.9%,25.1%,7.0%,6.8%,43.8%,0.6%,15.9%,and 6.1% among the residents,respectively.The prevalences of obesity,central obesity,and diabetes were higher among the females than those of among the males（P0.05）,whereas the males had obviously higher proportion of clustering of 2 or more CVD risk factors than the females.The prevalences of hypertension and diabetes increased with the number of CVD risk factors（P0.01）.Conclusion The CVD risk factors were prevalent among rural residents in the study area.Reducing the clustering of CVD risk factors would be helpful for decreasing the prevalence of hypertension and diabetes.
