体重指数、腰围／臀围比与血压、血脂的相关性

本研究于１９９３年在北京地区抽取２５～６４岁的男女两性１２８２人，分析了体重指数（ＢＭＩ）、腰围／臀围比（ＷＨＲ）与血压、血脂的相关性。结果显示：男女两性的ＢＭＩ和ＷＨＲ均随年龄的增加而增加；男性ＷＨＲ显著高于女性（Ｐ＜０．００１），而ＢＭＩ无性别差异（Ｐ＝０．０６）。控制其它危险因素后，ＢＭＩ与男女两性的舒张压正相关；ＷＨＲ与血压的相关无显著性。ＢＭＩ、ＷＨＲ均与血脂独立相关，ＷＨＲ与血脂的相关性强于ＢＭＩ与血脂的相关性。本研究结果提示：ＢＭＩ反映的是调整身高后的体重值，它与血压的相关性较强；ＷＨＲ反映的是脂肪分布，它与血脂的相关性较强。此结果对高血压、高脂血症的防治具有重要的指导意义。

Associations of Body Mass Index and Waist/Hip Ratio with Blood Pressure and Serum Lipids

The association of body mass index(BMI)and waist/hip ratio (WHR) with blood pressure and serum lipids was studied using the data of population survey in Beijing, 1993, which included 568 men and 714 women who were 25 - 64 years old. BMI and WHR increased with age in both males and females. Men had essentially similar BMI with women(P =0.06),while men had significantly higher values of WHR than women(P<0.001) .After controlling for other risk factors, BMI was associated significantly with diastolic blood pressure. WHR wasn't associated with blood pressure. Both BMI and WHR were associated with serum lipids(total cholesterol and HDL-cholesterol),while the relationshiop between WHR and serum lipids was stronger. These data suggested that BMI, the index of total body fat,associated with blood pressure well,while WHR, the index of they fat distribution,associated with serum lipids well.This conclusion is very important in the prevention and treatment for hypertension and hyperlipidemia.
