人体测量指标与心血管病危险因素的典型相关分析

The canonical Correlation of Human Body Parameters with Risk Factors of cardiovascular Disease

为探讨人体测量指标与心血管危险因素指标的相互关系 ,确定与心血管危险因素相关最密切的人体测量指标 ,对12 74名 2 0～ 6 0岁农村居民进行问卷和身高、体重、四围、血胆固醇、甘油三酯、高密度脂蛋白、血糖的测定。计算出体重指数(BMl)、腰臀比 (WHR)、腹臀比 (AHR)和锥削度指数 (CI)后 ,与血胆固醇、甘油三酯、高密度脂蛋白、血糖作典型相关分析。结果表明 :人体测量指标与心血管危险因素指标呈典型相关(典型相关系数 0 40 8～ 0 5 92 ) ;人体测量指标中 ,体重指数的贡献最大 ,与心血管因素的相关最密切。结论

In order to investigate the association between cardiovascular risk factors and a set of human body parameters,at the same time to determine which parameter correlated most highly with the risk factors. Collected data including body height and Weight,waist,abdominal and hip circumferences,and risk factors(serum total cholesterol,high density lipoprotein cholesterol,blooding sugar,systolic and diastolic blood pressure)were available from survey of cardiovascular risk factors in the residents of AnHui rural areas. After Calculation body mass index(BMI),waist/hip(WHR),abdominal/hip (AHR) and conicity index(CI),then the association of body parameters and risk factors was gained by SAS canonical correlation analysis, As the results point out:Canonical correlation were statistically significant between the body parameters and cardiovascular risk factors in all sex-age-specific groups.of the body parameters,BMI consistently demonstrates the highest correlation coefficients with cardiovascular risk factors. So the canonical correlation analysis indicates that BMI is the simplest but the most important of the body parameters for the risk of cardiovascular disease.
