Abstract: Objective To screen the high-risk population of stroke among the permanent residents aged ≥ 40 years in Haikou City, analyze the influencing factors affecting the detection of high-risk population of stroke, and provide the reference for the prevention and treatment of stroke. Methods From June to October 2022, a multi-stage random sampling method was adopted in Haikou City to screen the high-risk population of stroke among permanent residents aged ≥40 years. The descriptive method was used to analyze the detection of high-risk population of stroke and the distribution of risk factors, and univariate and multivariate analysis methods were used to analyze the influencing factors for high-risk of stroke. Results This study screened 1 680 residents and detected a total of 356 high-risk individuals for stroke, with a detection rate of 21.19%. The risk factors in the high-risk population of stroke were lack of exercise （74.16%）, dyslipidemia （73.60%）, overweight or obesity （58.15%）, hypertension （55.06%）, smoking （45.51%）, diabetes （29.21%）, family history of stroke （10.39%）, atrial fibrillation or valvular heart disease （3.93%）. Multivariate logistic regression analysis showed that male （OR=1.375）, age （OR=1.031）, average monthly income< 2 000 yuan （OR=2.101）, living in a city （OR=1.610） were influencing factors for high-risk of stroke. Conclusions The detection rate of high-risk population of stroke among residents in Haikou City is high. Lack of exercise and dyslipidemia were the main high-risk factors for residents in this area. Male, age, monthly income< 2 000 yuan, and city residence are the main factors affecting the detection of high-risk population of stroke.
