0089/2015 - Parâmetros de obesidade como preditores de desenvolvimento precoce de fatores de risco cardiometabólicos Obesity parameters as predictors of early development of cardiometabolic risk factors
O objetivo deste estudo foi verificar associação entre diferentes parâmetros de sobrepeso e obesidade com o perfil de risco metabólico em escolares. Este estudo transversal randomizado incluiu 1.254 crianças e adolescentes, com idades entre 7 a 17 anos, de uma cidade do sul do Brasil. O índice de massa corporal (IMC), a circunferência da cintura (CC) e o percentual de gordura (PG), avaliado através das medidas das dobras cutâneas tricipital e subescapular, foram usados como parâmetros para avaliar sobrepeso/obesidade. Pressão arterial sistólica (PAS), colesterol total, lipoproteína de alta densidade (HDL), lipoproteína de baixa densidade (LDL) e triglicerídeos também foram mensurados. O perfil de risco metabólico foi calculado com base no somatório do escore z das variáveis metabólicas ajustadas por idade. Três modelos de regressão de Poisson foram utlizados para verificar a associação entre IMC, CC e PG com o perfil de risco metabólico. Os dados demostram que o IMC foi o parâmetro que apresentou a maior associação com o desenvolvimento de risco metabólico (sobrepeso - razão de prevalência [RP]: 2,24 e obesidade - RP: 4,49), em comparação com CC (sobrepeso - RP: 1,63 e obesidade - RP: 3,87) e PG (sobrepeso - RP: 1,62 e obesidade - RP: 2,92). Conclui-se que o IMC parece ser um melhor parâmetro de sobrepeso/obesidade do que CC e PG, na avaliação do risco metabólico em escolares.

Abstract:
The purpose of this study was to verify the association between different parameters of youth overweight and obesity and the metabolic risk profile. A randomized cross-sectional study included 1254 children and adolescents, aged 7 to 17, from a city in southern Brazil. Body mass index (BMI), waist circumference (WC) and percentage of fat (PF), measured at the triceps and based on subscapular skinfold thickness, were used as the parameters to evaluate overweight/obesity status. Systolic blood pressure (SBP), total cholesterol, high-density lipoprotein cholesterol (HDL), low-density protein cholesterol (LDL) and triglycerides were also measured. The metabolic risk profile was calculated based on the sum of the z score of the metabolic variables adjusted by age. A three-model Poisson analysis was used to verify the association between BMI, WC and PF with metabolic risk profile. BMI showed the highest probability for developing metabolic risk (overweight – prevalence ratio [PR]: 2.24 and obesity – PR: 4.49) compared with WC (overweight - PR: 1.63 and obesity – PR: 3.87) and PF (overweight – PR: 1.62 and obesity – PR: 2.92). In conclusion, BMI seems to be a better parameter of overweight/obesity than WC and PF in the assessment of metabolic risk in youth.
