Abstract: Objective To understand the exposure level and distribution characteristics of risk factors in population at high-risk of stroke in a community in Shanghai,and to put forward ways to a comprehensive community intervention for risk factors. Methods From June to July in 2015,1 142 permanent residents aged 40 and above were random cluster sampled and investigated by using a questionnaire and physical examination. Results The prevalence of at high-risk of stroke was 74.7%.Hypertension,less movement,dyslipidemia,family history of stroke,diabetes,apparently overweight,smoking,atrial fibrillation or valvular heart disease were as risk factors for stroke in turn.There were differences between different gender and age patients in the exposure factor distribution.Women have a higher exposure rate in history of stroke,history of TIA and dyslipidemia than men.Men have a higher exposure rate in smoking than women.The exposure rate of the history of stroke,hypertension,atrial fibrillation or valvular heart disease,diabetes increased with age.The exposure rate of smoking and family history of stroke in 40-49 and 50-59 age groups were more outstanding as compared with other age groups.Logistic analyses showed that age,education level,physical exercise and sleep disorder were all correlated with the incidence of stroke(P<0.05). Conclusion The exposure rate of risk factors for stroke in high-risk population is high.The prevention and control of risk factors for stroke in community,strengthening the management of blood pressure,blood glucose and blood lipid,changing the poor diet and living habits,making health education according to different people is benefit to prevention and control of stroke in community.
