摘要
目的:探讨腰围、腰围/身高比值、腰臀比与血压的相关性,明确各指标对血压的影响大小,为临床工作提供指导。方法:以重庆市2003~2004年主城区9所中学和15所小学,12个年级5~17岁的学生7326名(男3603名,女3723名)为研究对象,测量身高、体重、腰围、臀围。计算体质指数、腰围/身高比值及腰臀比。血压与各人体测量指标之间的关系分析采用偏相关分析方法和多元逐步线性回归。结果:男童的血压异常率为4.61%,女童为3.06%,总体人群的异常率为3.86%。偏相关分析显示:腰围、腰围/身高比值与血压独立正相关,且腰围的正相关性最强,其次为腰围/身高比值,而腰臀比相关性稍差。以腰围≥90百分位,腰围/身高比值≥0.5,腰臀比女童≥0.85,男童≥0.90为异常,男女童腰围、腰围/身高比值异常组的血压均值明显高于腰围、腰围/身高比值正常组的值。腰臀比正常和异常组之间的血压均值差距较小。多元逐步线性回归结果示:年龄、腰围、腰围/身高比值、腰臀比均为收缩压和舒张压的影响因素。腰围、腰围/身高比值的影响较腰臀比大,其中腰围影响最大。校正的OR值显示男女童腰围和腰围/身高比值异常者血压异常的风险是正常者的6~7倍,明显高于腰臀比的风险。结论:腰围、腰围/身高比值与血压的改变有良好的相关性,是预测血压水平变化的较好指标。其中腰围预测性最好,其次为腰围/身高比值,腰臀比的预测能力有限。
Objective:To investigate the relationships between waist circumference(WC ) ,waist circumference to height ratio( WHtR ), waist to hip ratio(WHR) and blood pressure. Methods : A school based, cross-sectional study was conducted in the urban Chongqing in 2003 and 2004. A total 7 326 (3 603 boys) Han students aged 5 to 17 years were recruited from 15 primary schools and 9 secondary schools. Weight, height, WC, and hip circumference were measured according to the international criteria and blood pressure was measured with the mercury sphygmomanometer. The body mass index( BMI ), WHtR and WHR were calculated. The relations between blood pressure and different anthropometric variables in both genders were investigated in partial correlation analysis and stepwise multiple regression analysis. Results: The prevalence of abnormal blood pressure was 3.86%(4.61% for boys, 3.06% for girls ). WC and WHtR were positively related with systolic blood pressure and diastolic blood pressure in hoth sexes and WC was the most relevant, whereas the relationships with WHR were less consistent. The differences of WC and WHtR between normal groups and abnormal groups (WC≥ 90th, WHtR≥ 0.5, WHR≥ 0.85 for girls, WHR≥0.90 for boys) were more significant than that of WHR. Using stepwise multiple regression analysis to explain the variance of blood pressure, age, WC, WHtR, WHR were influence factors of systolic and diastolic blood pressure. WC was the most significant predictor for all variables both for boys and girls, whereas WHR had the lowest predictive value for the detection of blood pressure. Adjusted odds ratios for predicting pathological values of blood pressure were significant higher for the highest WHtR and WC groups ( 6 - 7 times ). Conclusion:WC and WHtR are independently related to blood pressure level in children and adolescents and WC is the best predictor of the risk of hypertension, followed by WHtR, WHR is the last.
