0404/2024 - Parâmetros Antropométricos e Predição de Risco para Pressão Arterial Alterada na Adolescência Anthropometric Parameters and Altered Blood Pressure Risk Prediction in Adolescents
Fundamento: Excesso de peso têm sido associados a pressão arterial elevada (PAE) ou hipertensão arterial (HA) entre adolescentes. Objetivos: Avaliar prevalência e capacidade preditiva de variáveis antropométricas para PA alterada (PAA) (PAE + HA) em adolescentes. Métodos: Estudo transversal incluindo indivíduos entre 13 e 18 anos de idade, que avaliou a associação entre PAA e circunferência da cintura (CC), índice de massa corporal (IMC) e razão estatura-cintura (REC). A capacidade preditiva para PAA foi testada por análise da curva ROC. Resultados: Amostra de 328 indivíduos, 51% de sexo feminino, 23% com sobrepeso e 10% obesos, CC de 77 (IQR 77,3-84,3) cm e REC de 0,46 (IQR 0,44-0,51). A prevalência de PAE e de HA foram de 6% e 7%, respectivamente. A PAA predominou entre indivíduos do sexo masculino (p=0,01), obesos (p=0,03) e com maiores CC (p<0,001) e REC (p=0,007). Na predição de HA, a CC apresentou a maior área sob a curva (0.71) em comparação a REC (0.64) (p=0.02), e similar ao IMC (0.65) (p=0,14). Conclusões: A circunferência da cintura, medida de fácil obtenção, apresentou desempenho similar aos demais parâmetros antropométricos na predição de risco para PAA na presente amostra de adolescentes brasileiros.
Background: Elevated blood pressure (EBP) or high blood pressure (HBP) has been frequently linked to excess weight in adolescents. Objectives: To assess the association between altered blood pressure (ABP), including EBP and HBP, and anthropometric parameters. Methods: This cross-sectional study evaluated the association of ABP with waist circumference (WC), body mass index (BMI), and height-to-waist ratio (HWR) among adolescents aged between 13 and 18 years. Predictive performance for ABP was evaluated using receiver operating characteristic (ROC) curve analysis. Results: The study comprised 328 individuals, 51% female, 23% overweight, and 10% obese. The median WC was 77 cm (interquartile range [IQR]: 77.3-84.3 cm), and the medin HWR was 0.46 (IQR: 0.44-0.51). EBP was found to be more prevalent among males (p=0.01) and obese participants (p=0.03), with higher HWR (p=0.007) and WC (p<0.001). Regarding the prediction of HBP, WC demonstrated a larger area under the curve (0.71) compared to HWR (0.64) (p=0.02), although similar to BMI (0.65) (p=0.14). Conclusions: Waist circumference, a readily obtainable measure, exhibited predictive performance comparable to other anthropometric parameters in assessing the risk for ABP in this sample of Brazilian adolescents.
