【目的】探讨长沙市健康体检人员的体质量指数（BMI）对血压与血脂的影响，为预防与控制血压及血脂异常提供依据。【方法】随机选择400例来自长沙市在湘雅医院参加健康体检的成人，按BM I不同将研究对象分为体重过轻组、正常组、超重组和肥胖组，采用单因素logistic回归及多因素logistic回归分析BM I对血压与血脂的影响。【结果】体质量过轻组高血压、高血脂患病率低于正常组，而超重组和肥胖组高血压、高血脂患病率明显高于正常组，且差异均有统计学意义（均 P ＜00．5）。单因素logistic回归结果显示，超重组与肥胖组高血压、高血脂的患病风险显著高于正常组，差异均具有统计学意义（均 P ＜00．5）；多因素logistic回归结果显示，超重组与肥胖组高血压、高血脂的患病风险显著高于正常组，差异均具有统计学意义（均 P ＜00．5）；年龄仅对是否患高血压有显著影响，差异具有统计学意义（ P ＜00．5）；对是否患高血脂并无显著影响（ P ＞00．5）。【结论】超重或肥胖是高血压、高血脂患病的危险因素，应加强相关的健康教育工作。“,”Objective]To explore the effect of BMI on body pressure and lipid among people in Changsha so as to provide evidences for prevention and control of body pressure and Lipid abnormality [. Methods] A to‐tal of 400 cases were randomly selected in ordinary adults who participated in health examination in Xiangya Hospital and were grouped into the lighter weight ,the normal ,the overweight and he obesity according to BMI .The effect of BMI on blood pressure and blood lipid was analyzed by single factor Logistic regression and multiple logistic regression analysis[.Results ]The prevalence of hypertension and hyperlipidemia in the light weight group was lower than that in the normal BMI group ,but the prevalence of hypertension and hyperlipi‐demia in the overweight group and the obesity group was higher than that in the normal BMI group ,and the differences were statistically significant ( P <0 0.5) .Single factor Logistic regression analysis showed that the prevalence of hypertension and hyperlipidemia in the overweight group and the obesity group were significantly higher than those in the normal group ,the difference was statistically significant ( P <0 0.5);Multi factor Lo‐gistic regression results showed that the prevalence of hypertension and high blood lipid was significantly high‐er than that in the normal group ,and the difference was statistically significant ( P <0 0.5);Age had a signifi‐cant effect only on whether or not with hypertension ,there was significant difference ( P 0 0.5) .[Conclusion]Overweight or obesity is a risk factor for hypertension and hyperlipidemia .Corresponding health education need to be strengthened .
