林区居民高血压患病率及相关因素的横断面研究

Cross-sectional study of prevalence of hypertension and its risk factors in forest dwellers

目的了解浙江省遂昌县林区居民高血压的患病率及影响因素。方法采用随机整群抽样方法抽取遂昌县白马山林区≥18岁社区居民2007人，进行问卷调查、体格检查及生化指标检测。结果该县林区居民患高血压病474例，患病率为23．62％，标化患病率为18.09％。高血压患病率随年龄增加而增加，且不同年龄段患病率具有性别差异：〈40岁，男性患病率大于女性；≥50岁，女性患病率显著高于男性；40～50岁，两者相当。多因素Logistic回归分析显示，性别、年龄、BMI、家族史、糖代谢异常、脂代谢异常为高血压患病的危险因素。结论遂昌县林区居民高血压患病率较全国水平低，但老年高血压患病率明显升高，性别、年龄、家族史、肥胖、糖和脂代谢异常是高血压患病的主要危险因素。

Objective To investigate the prevalence rate of hypertension and its risk factors in forest residents from Suichang County, Zhejiang province. Methods A cross-section survey on prevalence of hypertension was conducted in the forest area of Suichang County, 2 007 residents aged ≥ 18y were randomly selected by using cluster sampling method. Results The crude prevalence rate of hypertension was 23.62% （474/2007）, and the age-adjusted rate was 18.09% as calculated by the age distribution of latest national survey. The prevalence rate of hypertension increased with age. The gender differences in the prevalence rate varied with the age： in 〈40 y age group the prevalence of males was higher than that of females, in ≥50y age group the prevalence of females was higher than that of males, while there was no difference in age 40 - 50y group. Multivariate logistic regression analysis showed that the risk factors of hypertension included gender, age, family history, BMI, abnormal glucose metabolism and lipid metabolism. Conclusion The prevalence rate of hypertension is lower than the national level in forest area in Suichang County. The main risk factors of hypertension included gender, age, family history, obesity, and metabolism disorders of glucose and lipid.
