Asociación entre adiposidad y factores de riesgo cardiovascular en infantes pre-púberes

Introduction and objectives: To examine the relationships between of four measures of adiposity, namely waist circumference (WC), body mass index (BMI), and subscapular and abdominal skinfolds, with different cardiovascular risk factors in prepubertal children. Methods: Four hundred and ninety-four prepubertal children aged 6-10 years participated in this cross-sectional study. The subscapular and abdominal skinfolds, WC, and BMI were measured to assess adiposity, and cardiovascular risk factors (CVRFs) were assessed by measuring systolic (SBP) and diastolic blood pressures (DBP), glucose, triglycerides (TG), and high density (HDL-C) and low density lipoprotein cholesterol (LDL-C). Dichotomous variables were created based on whether or not the subjects were in the upper quartile (Q4) for the WC, BMI, and skinfold variables. Results: No CVRF was found in 52.8% of children, 33.4% had one factor, and 10.9% and 2.8% had 2 and 3 factors respectively. An adjusted logistic regression analysis showed that being in Q4 of anthropometric variables and CVRFs was associated to TG levels ≥ 100. mg/dL. Glucose levels ≥ 96. mg/dL were associated to Q4 and abdominal fold. Presence of 2 or more CVRFs was significantly associated to Q4 in all anthropometric variables despite adjustment for age, gender, and calorie intake. The subscapular skinfold was the adiposity marker associated to the highest risk. Conclusions: Children with a more unfavorable adiposity profile tend to have a greater cardiovascular risk in the prepubertal stage.
