一个新的肥胖指数与女工血压关系的评价

EVALUATION OF A NEW OBESITY INDEX AND ITS RELATIONSHIP WITH BLOLD PRESSURE IN FEMALE WORKERS

本文用新的肥胖指标──锥削度指数（简称Ｃ指数）评价了１５５７名女性职工ｃ指数与血压的关系。按Ｃ指数４等份，临界与确诊高血压的检出率显著增高（４组ＯＲ值依次为１．００、１．１０、１．５１和２．２７；Ｐ＜０．０１）。Ｃ指数与血压水平间显著相关（它与收缩压、舒张压的相关系数分别为０．２０和０．ｌｌ，两者Ｐ值均小于０．００１）。经多元统计调整年龄后，它与舒张压的显著性消失，而与收缩压水平显著相关（ｒ＝０．１３，Ｐ＜０．００１）。进一步调整体质指数（ＢＭＩ）或腰／臀比（ＷＨＲ）后，统计显著性仍存在（Ｐ＜０．０１）。再同时调整年龄、ＢＭＩ与ＷＨＲ后，Ｃ指数与收缩压依然有统计学意义（Ｐ＜０．０ｌ）。表明Ｃ指数与收缩压的联系是独立于ＢＭＩ和或ＷＨＲ的；提示Ｃ指数是从另一方面（即不依赖于相对体重和上身性肥胖）反映肥胖特征。

new obesity index was proposed called conicity index(Cindex),with the formula abdominal circumference(0.09 weight/height),recently.The relationspip of C ondex to blcod pressure was assessed in 1557 female workers with the average age of 36.The prevalence of borderline and definite hypertensives were remarkably increa sed with the C index(odds ratio was1.00,1.10,1.51and2.27 andP<0.01)。The statistical significant correlat ion be tween C index a ndblood pressure levels was found(r=0.20/SBP,r=0.11/DBP,P<0.001 for both).For multi-statistics adjustment bythe age,there was no significant difference between C indexand DBP but found it between C index and SBP whose partialcorrelation coefficient was r=0.13 andp<0.O0 1,further ad-justing for BMl or WHR,this statistical significant differencewas still found ,which suggested that C index might be inde-pendent of BMI and WHR to reflect the aspect of the body fatdistribution。Therefore we recommend that C index can beused as a routine index of obesity in cardiovascular epidemio-logical study but it was needed to be proved out in prospectivepopulation-based study for the prediction。
