Abstract：Objective To investigate the exposure level of risk factors among high-risk stroke population and distribution characteristics of the population in Baoshan district, Shanghai, and to provide suggestions for stroke prevention and control. Methods A random cluster sampling method was used to select 20,374 permanent residents aged 35 years and above in Baoshan district in 2018, and their general information, history of diseases and risk factors for stroke were investigated. Results Among the 20,374 residents surveyed, 3,693 (18.13%) cases at high risk of developing stroke were detected, including 1,015 (4.98%) cases with stroke history or transient ischemic attack and 2,678 (13.14%) cases with three or more than three brain stroke risk factors. Among the 2,678 high-risk cases, the high risk detection rate was significantly higher in males than in females (19.51% vs. 17.10%), showing a statistically significant difference (P<0.05). And the high risk detection rate increased with the increasing age (P<0.001). Among the 2,678 residents with three or more than three brain stroke risk factors, the proportion of cases with three risk factors was the highest (74.57%, 1,997/2,678). The exposure rates of risk factors in the high-risk stroke population were hypertension (87.71%), lack of physical exercise (75.62%), BMI ≥ 26 kg/m2 (51.17%), diabetes mellitus (43.35%), dyslipidemia (38.20%), cigarette smoking (22.52%), family history of stroke (15.72%) and history of atrial fibrillation (1.79%). The exposure rate of cigarette smoking was significantly higher in males than in females, while the exposure rates of dyslipidemia, diabetes mellitus, lack of physical exercise, BMI ≥26 kg/m2 and family history of stroke were higher in females than in males, with statistically significant differences (all P<0.05). Conclusions The exposure rates of risk factors among high-risk stroke population in Baoshan district, Shanghai are high; and hence, measures should be taken actively to strengthen physical exercise and control blood pressure and body weight.
