人体测量指标与血脂、血糖及血压水平的典型相关

The Canonical Correlation of Anthropometric Parameters With Blood Lipids,Blood Sugar and Blood Pressure

目的：探讨人体测量指标与心血管危险因素水平的相互关系，确定与心血管危险因素相关最密切的人体测量指标。方法：在江苏省金坛县农村抽取３５～５９岁自然人群（男４９２名；女６０６名），测量身高、体重、腰围、腹围、臀围和血胆固醇、高密度脂蛋白胆固醇、血糖、收缩压、舒张压，计算出体重指数（ＢＭＩ）、腰／臀比（ＷＨＲ）、腹／臀比（ＡＨＲ）和锥削度指数（ＣＩ）后，与血脂、血糖及血压水平作典型相关分析。结果：人体测量指标与心血管危险因素指标呈典型相关（典型相关系数为０．３１～０．５０）；人体测量指标中，体重指数的贡献最大，与心血管危险因素的相关最密切；血压是心血管危险因素中与人体测量相关最密切的指标。结论：体重指数是本组人群中最简单但最有价值的人体测量指标；而血压是受肥胖影响最大的心血管危险因素指标。

Objective:Multivariate association was sought between cardiovascular risk factor levels and a set of anthropometric variables,to determine which anthropometric parameter correlated most highly with the risk factors. Methods:Data including body height and weight;waist,abdominal and hip circumferences;and risk factors(serum total cholesterol,high density lipoprotein cholesterol,fasting blood sugar,systolic and diastolic blood pressure)were available from a survey of cardiovascular risk factors in free living individuals ( n =1 098)of Jiangsu rural area(1992).After calculating body mass index(BMI),waist/hip ratio(WHR),abdominal/hip ratio(AHR)and conicity index(CI),the association of a set of anthropometric parameters with the risk factors was explored by canonical correlation analysis. Results:Canonical correlations were statistically significant between the anthropometric parameters and cardiovascular risk factors in all sex age specific groups.Standardized canonical coefficients from canonical analysis suggested that the weight for BMI was the highest and positive in all sex age groups.Of the anthropometric variables,BMI consistently demonstrated the highest correlation coefficients with cardiovascular risk factors.Of the risk factor variables,the correlation coefficient of blood pressure was generally the highest. Conclusion:The canonical correlation analysis indicates that BMI,the simplest but most important of the anthropometric measurements,is most highly correlated with blood pressure.
