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

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(P<0.05),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(P<0.01).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.
