目的探讨天津市郊区中老年男性人群体质指数(BMI)与血脂及血压的关系。方法采用分层随机整群抽样的方法,对天津市郊区≥50岁的1424名男性居民按不同BMI分为体重正常组(388名,BMI<24kg/m2)、超重组(630名,24kg/m2≤BMI<28kg/m2)、肥胖组(406名,BMI≥28kg/m2),进行流行病学调查和血脂及血压检测。结果超重、肥胖组收缩压、舒张压、血清总胆固醇、甘油三酯、低密度脂蛋白胆固醇水平较体重正常组升高(P<0.01),高密度脂蛋白胆固醇降低(P<0.01);随BMI升高,血脂异常发生率以及1、2级高血压患病率均升高(P<0.05)。结论积极控制BMI对预防血脂异常、高血压的发生发展有重要意义。
Objective To explore the relationship between body mass index (BMI), blood fat and blood pressure in middle-aged and elderly male in suburban area of Tianjin. Methods Stratified stratified random cluster sampling method was used to classify 1424 male residents aged 50 years or older in Tianjin suburbs according to different BMI into normal weight group (388, BMI <24kg / m2), overweight group (630, 24kg / m2≤BMI <28kg / m2), obesity group (406, BMI≥28kg / m2), epidemiological survey and blood lipid and blood pressure test. The results were overweight. The systolic blood pressure, diastolic blood pressure, serum total cholesterol, triglyceride and low density lipoprotein cholesterol in obese group were significantly higher than those in normal weight group (P <0.01), while the levels of high density lipoprotein cholesterol (P <0.01) BMI increased, the incidence of dyslipidemia and the prevalence of grade 1 and 2 hypertension were increased (P <0.05). Conclusion The positive control of BMI is of great importance in the prevention and treatment of dyslipidemia and hypertension.
