A survey of the perceived risk for stroke among community residents in western urban China.

Abstract

BACKGROUND AND PURPOSE: Persons who perceive their risk for stroke can promote the intervention of stroke risk factors and reduce the risk of stroke occurrence. Our purpose was to assess the knowledge of stroke risk factors and the level of perceived risk for stroke. METHODS: In 2011, a population-based face-to-face interview survey was conducted in Yuzhong district, Chongqing. A total of 1500 potential participants aged ≥18 years old were selected using a multi-stage sampling method. The knowledge of stroke risk factors and perceived risk for stroke was surveyed. RESULTS: A total of 941 participants completed the questionnaire survey. The respondents' awareness rate of stroke risk factors ranged between 53.3% and 87.2%. The community residents' perceived risk for stroke was only 17.7%. Multiple logistic regression analysis showed that 45-64 years age group, a history of hypertension, hyperlipidemia, heart disease, and stroke were independent predictors of perceived risk for stroke. Perceived risk for stroke increased as the number of risk factors increased (P<0.001). However, even for respondents with three or more risk factors, only 41% perceived themselves to be at risk for stroke. CONCLUSIONS: In this population-based survey, few community residents perceived risk for stroke, even among those with multiple stroke risk factors, most did not perceive themselves to be at risk for stroke. Persons with 45-64 years old, a history of hypertension, hyperlipidemia, heart disease or stroke were more likely to perceive risk for stroke. The awareness of the risk for stroke has yet to be enhanced among community residents.
