PREVALENCE OF THE METABOLICALLY HEALTHY PHENOTYPE IN PEDIATRIC OBESITY AND ITS ASSOCIATION WITH CLINICAL, METABOLIC AND FAMILY HISTORY PARAMETERS

Background and objectives: Identifying the presence of the metabolically healthy (MH) phenotype and the factors to which it is associated in pediatric obesity, allows early detection of those who have a lower risk of future cardiometabolic complication and treatment adequation. Therefore, the objective of this study is to estimate the prevalence of MH phenotype in overweight/obesity children and adolescents and its association with clinical, metabolic and family history parameters. Methods: 203 patients were studied, age range 8-14 years, both sexes, overweight (n=59) and obese (n=144), according to z score BMI (OMS), in the section of Pediatric Nutrition, February 2005-October 2016. Exclusion criteria: patients with endogenous obesity. The design was descriptive, observational, prospective, cross-sectional and comparison of independent samples. Evaluated variables: age, sex, z score BMI, pubertal development, HOMA-IR, family history (FH) of obesity, type 2 diabetes, arterial hypertension, dyslipidemia and early acute myocardial infarct. The MH phenotype was defined by the absence of any components of the metabolic syndrome (MS) according to the criteria of the Argentine Society of Pediatrics. Fisher's test was performed and p-value
