体质指数和腰围对肥胖儿童青少年高血压的影响

Impact of BMI and waist circumference on the screening of hypertension in obesity children and adolescence

目的探讨体质指数和腰围对肥胖儿童青少年高血压的影响。方法测量上海市市区两所中学 2 0 6 4名 10～ 18岁儿童青少年和肥胖病专科初诊 7～ 18岁 4 70例单纯性肥胖患儿体重、身高、血压和腰围。结果 2 0 6 4名在校学生高血压检出率为3.7% ,其中高血压在正常体重学生中检出率为 2 .5 % ,超重学生为 7.0 % ,肥胖学生为 12 .6 %。专科初诊 4 70例肥胖儿童高血压发病率为 39.4 % ,其中超重儿童高血压发病率为 10 .9% ,肥胖儿童为 4 2 .5 %。正常体重、超重和肥胖儿童高血压检出率组间有显著差异 (P =0 .0 0 1)。结论在校学生高血压检出率随体质指数增加而明显增高。儿童青少年单纯性肥胖病体质指数、腰围与收缩压、舒张压呈直线正相关。

Objective To explore the relation between body mass index(BMI), waist circumference and hypertension in obesity children. Methods Body weight, height and blood pressure were measured in 2 064 school children (10～18 year of age) and 470 diagnosed obesity children (7～18 years of age). Results The prevalence of hypertension in 2 064 school children is 3.7%, among which the prevalence of hypertension is 2.5% in normal weight children, 7.0% in overweight and 12.6% in obesity. The morbidity of hypertension in 470 diagnosed obesity children is 39.4%, among which the morbidity of hypertension is 10.9% in overweight and 42.5% in obesity. There was significant difference in the prevalence of hypertension among normal weight children, overweight and obesity. Conclusion The morbidity of hypertension increased obviously with the increase of BMI in school children. Systolic and diastolic blood pressure were positively correlated with body weight and waist circumference in diagnosed obesity children.
