| Objective To analysis the prevalence and risk factors of coronary heart disease among senior intellectuals in Hefei city and to provide reference for further prevention and control of chronic disease; To set a aquantitative criteria for determining risks for coronary heart disease (CHD) so that potential risks of an individual morbidit of CHD can be identified and to lay a foundation for predicting individual risks of CHD and to explore the factual usage of the methods and tools of the 10-year's risk estimation of CHD.Methods Total 4726 above 35 years old subjects were selected by cluster sampling. The comparison of the prevalence rate of the CHD by gender and age, non-conditional logistic regression analysis were performed. Data of case-control studies published during 1995 to 2005, as well as data of surveillance of behavior exposure, were collected by retrieval of literatures. Pooled odds ratios (OR) of all risk factors of CHD were estimated using various statistical models with software for meta-analysis, and attributable risk fractions of varied levels of risk factors could be converted at an interval of five years. The risks of CHD in 4574 middle-elderly subjects were evaluated by the methods and tools of the 10-year risk estimation of CHD, which was developed by meta-analysis and epidemiology investigation of CHD.Results The prevalence rate of CHD was 5.6%, increasing along with age. Age, sex, family history of CHD, hypertension, WHR and salt intake were the main risk...
