目的探讨天津市农村人群体质指数(BMI)与脑卒中发病的关系。方法以整群随机抽样的方法,于1991年9月在天津市蓟县某镇选取6个自然村15岁及以上常住人口4796人为基线研究对象,进行流行病学问卷调查,测量血压、身高、体重。用前瞻性队列研究的方法,每年随访队列人群的脑卒中事件,并进行全死因登记,至2009年9月共随访18年。分析不同BMI水平脑卒中发病的相对危险度(RR)。结果脑卒中发病与BMI水平明显有关,与正常体重组比较,体重过低组、超重组、肥胖组发生出血性卒中的RR值分别为2.7,1.9和3.5,缺血性卒中的发病危险在超重组和肥胖组明显增加,RR值分别为1.4和2.4;60岁以下人群体重过低组出血性卒中的发病风险最高(RR=10);60岁以上人群仅显示肥胖组有较高的缺血性卒中发病危险。结论农村肥胖人群有较高的脑卒中发病风险,特别是60岁以下人群,体重过低者易患出血性卒中。
Objective To explore the relationship between body mass index (BMI) and stroke in Tianjin rural population. Methods A total of 4796 permanent residents aged 15 years and over in 6 villages in Jixian Town, Tianjin City were selected as the baseline subjects in a randomized cluster sampling study in September 1991 to conduct epidemiological survey and measure blood pressure, height and weight. In a prospective cohort study, stroke events in the cohort were followed each year and all-cause registry was performed. Until September 2009, a total of 18 years of follow-up was conducted. The relative risk (RR) of stroke with different BMI levels was analyzed. Results The incidence of stroke was significantly related to the level of BMI. Compared with the normal weight group, the RR of hemorrhagic stroke in underweight group, overweight group and obesity group were 2.7, 1.9 and 3.5, respectively. The risk of ischemic stroke in ultrasonography The risk of hemorrhagic stroke was significantly higher in the overweight group (RR = 10), and the over 60 years old group only showed the higher ischemia in the obesity group Risk of stroke. Conclusion Rural obese people have a higher risk of stroke, especially those under 60 years of age. Those who are underweight are predisposed to hemorrhagic stroke.
