DURA-TRAVE, Teodoro et al. Changes in body composition and cardiometabolic risk factors in relation to the reduction in body mass index in adolescents with obesity. []. , 39, 2, pp.273-281. 09--2022. ISSN 1699-5198. https://dx.doi.org/10.20960/nh.03809.
Introduction:
there are controversial data in relation to the reduction in body mass index standard deviation score (BMI-SDS) needed to improve adiposity in the pediatric population with obesity. The aim of this work was to determine the minimum variation in BMI-SDS required to improve the values of adiposity markers and cardiometabolic risk factors in growing adolescents with obesity.
Methods:
a longitudinal study consisting of clinical evaluation (waist circumference, waist-to-height ratio, fat mass index, and blood pressure) and blood testing (insulin resistance and lipid profile) was conducted in 350 adolescents with obesity (152 boys and 198 girls) aged 10.2-14.3 years who went through a combined intervention (12 months).
Results:
a decrease in SDS-BMI ≤ 0.5 was not associated with any significant improvement in the clinical features and blood testing recorded. A decrease in BMI-SDS > 0.5, and especially if > 1.0, was linked to a significant improvement in adiposity markers. A decrease in BMI-SDS > 0.5 was associated with a significant improvement in insulin resistance, and a decrease in BMI-SDS > 1.0 was associated with a significant decrease in the percentage of patients who showed high values of systolic blood pressure, HOMA-IR, and lipid profile
Conclusions:
improvement in body composition, insulin resistance, and lipid profile can be observed with reductions in BMI-SDS ≥ 0.5 in obese adolescents, while extended benefits are obtained by losing at least 1.0 BMI-SDS.
