High blood pressure is strongly associated with obesity in different populations. However, it is unclear whether different anthropometric indicators of obesity can satisfactorily predict high blood pressure in the school setting.
This study evaluated the sensitivity and specificity of body mass index, waist circumference, and waist to height ratio in the detection of high blood pressure in adolescents.
The sample consisted of 8295 adolescents aged 10-17 years. Weight was measured using a digital scale, height with a stadiometer, and waist circumference using a tape measure. Blood pressure was measured by an automatic blood pressure measuring device. ROC curves were used for the analysis of sensitivity and specificity of the three anthropometric indices in identifying high blood pressure. Binary Logistic Regression was used to assess the association of body mass index, waist circumference, and waist to height ratio with high blood pressure.
Low values of sensitivity were observed for body mass index (0.35), waist circumference (0.37), and waist to height ratio (0.31) and high values of specificity for body mass index (0.86), waist circumference (0.82), and waist to height ratio (0.83) in the detection of high blood pressure. An association was observed between adolescents classified with high body mass index (OR=3.57 [95% CI=3.10-4.10]), waist cirumference (OR=3.24 [95% CI=2.83-3.72]), and waist to height ratio (OR=2.94 [95% CI=2.54-3.40]) with high blood pressure.
Body mass index, waist circumference, and waist to height ratio presented low sensitivity to identify adolescents with high blood pressure. However, adolescents classified with high body mass index, waist circumference, and waist to height ratio demonstrated a high association of presenting high blood pressure.
高血压在不同人群中与肥胖密切相关。然而，不同的肥胖人体测量指标是否能令人满意地预测学校环境中的高血压尚不清楚。
本研究评估了体质指数、腰围和腰高比在青少年高血压检测中的敏感性和特异性。
该样本包括 8295 名 10-17 岁的青少年。体重采用电子秤测量，身高采用测高仪测量，腰围采用卷尺测量。血压采用自动血压测量装置测量。ROC 曲线用于分析三种人体测量指标识别高血压的敏感性和特异性。二元逻辑回归用于评估体质指数、腰围和腰高比与高血压的相关性。
体质指数（0.35）、腰围（0.37）和腰高比（0.31）的敏感性值较低，而体质指数（0.86）、腰围（0.82）和腰高比（0.83）的特异性值较高，用于检测高血压。高体质指数（OR=3.57[95%CI=3.10-4.10]）、高腰围（OR=3.24[95%CI=2.83-3.72]）和高腰高比（OR=2.94[95%CI=2.54-3.40]）的青少年与高血压有关。
体质指数、腰围和腰高比对识别高血压青少年的敏感性较低。然而，被归类为高体质指数、高腰围和高腰高比的青少年与高血压的高关联性。
