Abstract:
Objective To explore the prevalence and risk factors of stroke in a population over 40 years in a community in Shenzhen, China. Methods The subjects investigated were a population ≥40 years old in this cross-sectional study. Cluster sampling method was used to conduct the unified questionnaires, physical examination, and laboratory examination in the community residents, and then the survey data were used for online entry analysis. Results A total of 5 308 community residents were screened, and 160 experienced stroke. The crude prevalence of stroke was 3 014. 32/100 000. The prevalence of stroke increased with age, and that in males was significantly higher than that in females (3 721. 37/100 000 vs. 2 552. 93/100 000; χ2 = 5. 923, P = 0. 015). There were significant differences in the proportions of males, obvious overweight, hypertension, diabetes mellitus, atrial fibrillation, lack of physical activity, and family history of stroke, as well as age, systolic blood pressure, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and fasting glucose level between the stroke population and the non-stroke population (all P < 0. 05). Multivariate logistic regression analysis showed that hypertension (odds ratio [OR] 1. 737, 95% confidence interval [CI] 1. 161-2. 600; P = 0. 007), diabetes (OR 1. 917, 95% CI 1. 209-3. 040; P = 0. 006), atrial fibrillation (OR 1. 699, 95% CI 1. 113-2. 592; P = 0. 014), family history of stroke (OR 1. 585, 95% CI 1. 126-2. 231; P = 0. 008), advanced age (OR 4. 645, 95% CI 1. 868-11. 551; P = 0. 001), and physical inactivity (OR 4. 921, 95% CI 3. 552-6. 187; P < 0. 001) were the independent risk factors for stroke, and lack of physical activity was an independent protective factor for stroke. The proportion of smoking in males was more than that in females in all ages(all P < 0. 05). The proportions of hypertension (P < 0. 001) and hyperlipidemia (P < 0. 001) were gradually increased with age, and physical exercise was gradually reduced with age (P = 0. 001, except for subjects > 80 years) in both males and females. The proportions of diabetes (P < 0. 001) and atrial fibrillation (P < 0. 001) in males, and obvious overweight (P = 0. 001) in females were gradually increased with age, and the proportion of smoking in males weas gradually reduced with age. The proportions of hypertension (P < 0. 001) and obvious overweight (P < 0. 001) in males were significantly higher than those in females at the age of 40 to 49 years. The proportions of hypertension (P < 0. 001), diabetes (P < 0. 001) and obvious overweight (P < 0. 001) in males were significantly higher than those in females at the age of 50 to 59 years. The proportion of hypertension in males was significantly higher than that in females at the age of 60 to 69 years (P = 0. 039). The proportions of hypertension (P = 0. 016), atrial fibrillation (P = 0. 028) and hyperlipidemia (P = 0. 023) in females were significantly higher than those in males at the age of 70 to 79 years. The proportion of obvious overweight in females was significantly higher than that in males at the age of ≥80 years (P =0. 001). Conclusions The crude prevalence of stroke is higher among the community residents. The the levels of exposure to stroke risk factors including hypertension, diabetes and atrial fibrillation are higher. It may be important to intervene on these risk factors in community residents, especially in elders and those with family history of stroke.
