目的探讨五年制高职院校青少年学生各肥胖指标与血压的相关性,为青少年高血压的筛查、防治及卫生宣教提供理论依据。方法以南京市某五年制高职院校1 785名学生为调查对象,测量身高、体重、腰围、血压等指标,计算体质量指数、腰围及腰围身高比;通过控制年龄的偏相关分析,探讨各肥胖指标和血压的相关性,并对与高血压发生情况进行Logistic回归分析。结果学生体质量指数、腰围和腰围身高比均与血压呈正相关,以腰围身高比的相关性最强(与男生收缩压和舒张压的相关系数为0.477和0.166,女生为0.323和0.158);3个指标所界定的体重异常组收缩压和舒张压水平均升高(P<0.01或P<0.05);单因素Logistic回归分析结果显示,无论女生还是男生,3个肥胖指标所界定的体重异常组与正常组相比患高血压的风险均升高;调整年龄、性别因素后,以正常组为参照,多因素Logistic回归分析结果仍然显示,体重异常组患高血压的风险升高,其中腰围身高比肥胖组患高血压的风险最高(OR=13.73,95%CI=9.00~20.94)。结论高职院校学生3种肥胖指标中,腰围身高比与血压的相关性最强,腰围身高比肥胖组患高血压的分险最高,适宜作为青少年高血压防治的初筛指标。
Objective To explore the correlation between obesity indices and blood pressure in adolescent students in five-year vocational colleges and to provide a theoretical basis for the screening, prevention and treatment of adolescent hypertension and public health education. Methods A total of 1 785 students from a five-year vocational college in Nanjing City were enrolled in this study. Height, weight, waist circumference and blood pressure were measured to calculate body mass index, waist circumference and waist circumference ratio. By controlling partial age correlation, To explore the correlation between obesity index and blood pressure, and to analyze the occurrence of hypertension with Logistic regression. Results Body mass index, body mass index of waist circumference and waist circumference were positively correlated with blood pressure, with the highest relevance of waist circumference ratio (0.477 and 0.166 for systolic and diastolic pressures for boys and 0.323 and 0.158 for girls); 3 The indexes of systolic blood pressure and diastolic blood pressure in the abnormal weight group were all increased (P <0.01 or P <0.05). The results of univariate logistic regression analysis showed that, no matter the female or the male, the body weight abnormalities defined by three obesity indexes Compared with the normal group, the risk of high blood pressure was increased. After adjusting for age and gender, the multivariate Logistic regression analysis showed that the risk of high blood pressure was increased in the abnormal weight group, in which the waist circumference The highest risk of developing hypertension was in the obese group (OR = 13.73, 95% CI = 9.00 to 20.94). Conclusion Among the three kinds of obesity indicators of vocational college students, the correlation between waist height and blood pressure is the strongest. The height of waist circumference is the highest risk of hypertension in obesity group, which is suitable for the preliminary screening of prevention and treatment of adolescents.
