Abstract
Cerebrovascular disease (CVD) is the leading cause of death in many countries including China. Early diagnosis and risk assessment represent one of effective approaches to reduce the CVD-related mortality. The purpose of this study was to understand the prevalence and influencing factors of cerebrovascular disease among community residents in Qingyunpu District, Nanchang City, Jiangxi Province, and to construct a model of cerebrovascular disease risk index suitable for local community residents. A stratified cluster sampling method was used to sample 2147 community residents aged 40 and above, and the prevalence of cerebrovascular diseases and possible risk factors were investigated. It was found that the prevalence of cerebrovascular disease among local residents was 4.5%. Poisson regression analysis found that old age, lack of exercise, hypertension, diabetes, smoking, and family history of cerebrovascular disease are the main risk factors for local cerebrovascular disease. The relative risk ORs were 3.284, 2.306, 2.510, 3.194, 1.949, 2.315, respectively. For these six selected risk factors, a cerebrovascular disease risk prediction model was established using the Harvard Cancer Index method. The R value of the risk prediction model was 1.80 (sensitivity 81.8%, specificity 47.0%), which was able to well predict the risk of cerebrovascular disease among local residents. This provides a scientific basis for the further development of local cerebrovascular disease prevention and control work.
Highlights
Cerebrovascular disease mainly refers to the abnormal manifestations of the nervous system caused by cerebral vascular hemorrhage and infarction ischemia
The prevalence was significantly higher among males (6.3%), smokers (8.4%), and the participants who lack exercise (8.0%), with hypertension (6.6%), diabetes (10.5%), and a family history of the disease (7.9%)
The Poisson regression analysis showed that age, exercise habits, hypertension, diabetes, smoking, and family history of cerebrovascular disease were related to the participants’ cerebrovascular disease (Table 4)
Summary
Cerebrovascular disease mainly refers to the abnormal manifestations of the nervous system caused by cerebral vascular hemorrhage and infarction ischemia. It is characterized by sudden, dangerous, difficult-to-treat, and irreversible sequelae. Cerebrovascular disease has become one of the major global public health problems because of its high morbidity, disability, and mortality [3]. Practice has proved that health education, interventions for high-risk behaviors, and active treatment of hypertension and other related diseases can effectively control the occurrence of cerebrovascular disease, reduce its complications, and improve quality of life [10]. Studies have revealed a presence of low public awareness and low control rate regarding risk factors for cerebrovascular disease [11], which seriously
