目的探讨甘肃省7~18岁人群高血压检出情况以及与肥胖的关系。方法入选“2010年全国学生体质健康调研”数据中,甘肃省7~18岁汉族城乡学生的血压、腰围、身高和体质量等,男女各3300人;采用二分类多因素Logistic回归分析,评估体质量指数(BMI)、腰围/身高(WhTR)对高血压发生的影响程度。收缩压和(或)舒张压≥第95百分位为高血压。结果甘肃省7~18岁人群高血压检出率为9.71%,且以舒张压增高(单纯舒张压≥第95百分位)为主;超重和肥胖、腰围≥第75百分位、WhTR≥0.5(阳性暴露)是不同类型高血压的危险因素(均P<0.05),并且随着BMI、腰围百分位数等级增高,OR逐渐增大。结论超重和肥胖、腰围≥第75百分位、WhTR≥0.5对于不同类型高血压发生的影响程度不同;用腰围指标预测高血压风险较为敏感。
Objective To investigate the detection of hypertension and its relationship with obesity in 7 ~ 18 years old population in Gansu Province. Methods: According to the “2010 National Student Health Survey” data, blood pressure, waist circumference, height and weight of Han and urban residents aged 7-18 in Gansu Province were 3300. According to the two-factor multi-factor Logistic regression analysis, Assessment of body mass index (BMI), waist circumference / height (WhTR) on the impact of hypertension. Systolic and / or diastolic blood pressure ≥95th percentile is high blood pressure. Results The prevalence of hypertension was 9.71% in people aged 7-18 years old in Gansu Province, with the increase of diastolic blood pressure (simple diastolic blood pressure ≥ 95th percentile), overweight and obesity, waist circumference ≥ 75th percentile, WhTR≥ 0.5 (positive exposure) were risk factors for different types of hypertension (all P <0.05), and OR gradually increased as the BMI and waist circumference percentiles were increased. Conclusion Overweight and obesity, waist circumference≥75th percentile, WhTR ≥0.5 have different effects on the incidence of different types of hypertension; waist circumference index is more sensitive to predict the risk of hypertension.
