An Epidemiologic Survey About Risk Factors Of Coronary Heart Disease In Rural Community Of Yunnan Province

Objective To investigate the status of risk factors of coronary heartdisease in rural area of Yunnan Province and provide scientific evidences to theprevention and treatment of CHD. Methods540cases aged50-70years weresampled with stratified and cluster multistage sampling in11rural areas of4countriesof Yunnan.50-59ages244,60-70ages296.using SPSS11.0version of software fordata analysis. Results In this survey,the prevalence of hypertension,overweight andobesity,smoking,drinking,high cholesterol,low HDL and diabetes was42.4%,15.7%,36.7%,33.5%,36.8%,8.6%,0.56%. The rates of hypertension,overweight andobesity,drinking were different,having significant difference(P<0.01).In theHan,Yi,Lisu nationality,its prevalence of overweight and obesity was less than theBai and Naxi nationality,its rate of hypertension and drinking was less than Zangnationality(P<0.05). The prevalence of hypertension,obesity and low HDL increasedwith age(P<0.05). In the rate of overweight and obesity, women(18.7%) was higherthan men(12.5%)(P<0.05).However the prevalence of smoking,drinking,hypertension, men(66.1%、54.9%、47.5%) was higher than women(9.9%、14.1%、37.8%)(P<0.05).28.1%of subjects had no any risk factors,71.9%had at least one riskfactors.Male with2and3level clustering of risk factors was higher thanfemale(P<0.001).Aggregation degree of risk factors of CHD wasdifferent(P<0.05).The highest having3risk factors was44.4%in Naxinationality.There had no significant difference in Han and minoritynationality,between two age groups(P>0.05).Conclusion The prevalence of riskfactors CHD was at the higher levels in rural area of Yunnan, To reduce itsprevalence,full-scale measures of prevention and control is advised.
