The obesity and overweight epidemic, together with increasing cardiovascular disease, represent a major public health problem worldwide, and their occurrence in childhood and adolescence has increased in recent decades. The objective of this study was to assess the association between waist-to-height ratio (WHR) and the incidence of hypertension in adolescents.
We performed a cross-sectional study of adolescents aged 10-17 years of both sexes attending municipal schools in inland Rio Grande do Sul, Brazil. Using a secondary database, weight and height measurements, blood pressure, and waist circumference (WC) were analyzed and body mass index (BMI) and WHR were calculated. Blood pressure was classified according to the Brazilian hypertension guidelines, BMI according to the curves of the World Health Organization, and WC according to Taylor et al. The cutoff used for WHR was 0.50 for both sexes.
Of the 1030 adolescents studied, 29.6% (305) presented overweight/obesity and 30.4% (313) had hypertension; 24% (247) had high WC and 18.3% (189) presented high WHR. Participants with WHR ≥0.50 were 2.4 times more likely to have hypertension than those with WHR <0.50 (OR 2.39; 95% CI 1.73-3.32; p<0.001).
A positive association was found between WHR and the presence of hypertension in adolescents.
肥胖和超重流行，加上心血管疾病不断增加，是全球主要的公共卫生问题，近几十年来，这些问题在儿童和青少年中的发生率有所上升。本研究的目的是评估青少年腰高比（WHR）与高血压发病率之间的关联。
我们对巴西南里奥格兰德州内陆市立学校10至17岁的青少年进行了一项横断面研究。利用二级数据库，分析体重、身高测量值、血压和腰围（WC），并计算体重指数（BMI）和WHR。血压根据巴西高血压指南分类，BMI根据世界卫生组织的曲线分类，WC根据泰勒等人的标准分类。男女WHR的临界值均为0.50。
在研究的1030名青少年中，29.6%（305名）超重/肥胖，30.4%（313名）患有高血压；24%（247名）腰围高，18.3%（189名）腰高比高。腰高比≥0.50的参与者患高血压的可能性是腰高比<0.50的参与者的2.4倍（比值比2.39；95%置信区间1.73 - 3.32；p<0.001）。
发现青少年腰高比与高血压的存在之间存在正相关。
