There are few studies on how lifestyle factors and mental conditions modulate the cerebrovascular diseases (CBVD) mortality risk are rare in the Asian elderly.
To comprehensively assess the impact of lifestyle factors and mental conditions on the mortality risk of CBVD among the Chinese older adults.
Material and methods: This community-based prospective cohort study was based on the Beijing Longitudinal Study of Aging. We included 2101 participants aged ≥55 years who were interviewed in August 1992 and followed until December 2015. Baseline sociodemographic variables, lifestyle behaviors, and medical conditions were collected using a standard questionnaire. In addition, biochemical parameters, the Activities of Daily Living (ADL) scale, Center for Epidemiological Studies Depression (CES-D) scale, and Mini-Mental State Examination (MMSE) were performed. Hazard ratio (HR) and 95% confidence intervals (CI) was estimated from the competing risk model.
During the follow-up period, 576 (27.42%) CBVD events were documented. Multivariable analysis showed that hypertension (HR = 2.331, 95% CI = 1.652–3.288,P < 0.001), depression (HR=2.331, 95% CI=1.652-3.288, P < 0.001), cognitive impairment (HR=1.382, 95% CI=1.132-1.689, P < 0.001), and coronary heart diseases (HR=1.360, 95% CI=1.095-1.689, P = 0.005) were independently associated with CBVD, while body mass index, fasting blood glucose, triglycerides, drinking, and smoking were not associated with CBVD (all P > 0.05).
Males were at higher risk of CBVD than females. Age, gender, hypertension, cognitive impairment, and depression were associated with CBVD among the elderly in Beijing, China.
