Abstract：Objective To investigate the exposure level and distribution characteristics of risk factors for stroke among screening population and high-risk population in Dalian city, and to provide a scientific basis for intervention and management of high-risk population of stroke. Methods According to the requirements of the National Screening and Intervention Program for High-risk Groups of Stroke, a cluster random sampling method was used to screen high-risk groups of stroke among permanent residents over 40 years old in Dalian city from October 2013 to September 2015. Results A total of 12,041 residents were screened from October 2013 to September 2015, and 1,948 residents were at high risk of stroke, with the detection rate of 16.18%. There were 1,531 residents with three or more risk factors for stroke (with the detection rate of 12.71%). The exposure rates of risk factors for stroke, including lack of exercise, hypertension, overweight or obesity, dyslipidemia, smoking history, diabetes mellitus, family history of stroke, atrial fibrillation or valvular heart disease, and previous history of stroke or transient ischemic attacks (TIA), in the screened population were 35.57%, 22.43%, 19.56%, 17.64%, 11.46%, 7.91%, 6.38%, 5.73% and 3.46%, respectively. The exposure rates of inactivity, hypertension and dyslipidemia were higher in urban residents (42.92%, 24.12% and 20.63%, respectively) than in rural ones (24.34%, 19.85% and 13.07%, respectively), whereas the exposure rates of overweight or obesity and family history of stroke were both higher in rural residents (22.41%, 9.95%) than in urban ones (17.69%, 4.04%), with statistically significant differences (all P<0.05). The exposure rates of risk factors for stroke, including previous history of stroke or TIA, hypertension, dyslipidemia, lack of exercise, family history of stroke, overweight or obesity, diabetes mellitus, atrial fibrillation or valvular heart disease and smoking, in the 1,948 high-risk residents were 15.55%, 7.70%, 6.93%, 6.16%, 4.77%, 4.16%, 3.64%, 3.44% and 2.67%, respectively. The exposure rates of previous history of stroke or TIA and family history of stroke were both higher in the rural high-risk group than in the urban high-risk group (18.38% vs. 13.78%, 7.06% vs. 3.34%), while the exposure rate of inactivity was higher in the urban high-risk group than in the rural high-risk group (7.02% vs. 4.79%), with statistically significant differences between urban and rural groups (P<0.05). Conclusions It is necessary to strengthen the management of stroke-related risk factors with high exposure rate in screening population and high-risk population in Dalian region, control the level of risk factors, and further improve the ability and level of stroke prevention and treatment.
