ABSTRACT
Objective. The aim of this study was to assess the association of the homeostasis model assessment of insulin resistance (HOMA-IR) with metabolic syndrome (MS), diet and physical activity (PA) in 12 to 14 year old Mexican youngsters living in Chiapas, Mexico.
Materials and Methods. This was a crosssectional study with a random selection of 259 for 12 to 14 year old youngsters from private and public schools. Conventional methods were used to measure body weight, height and blood pressure. After a 12-hour fasting period, a blood sample was taken for biochemical assessment. Weight-for-age, height-for-age and BMI-for-age were calculated using the CDC tables for growth. MS was defined as having three or more of the following conditions: BMI (age-specific 90
th percentile according to the CDC Growth Charts); systolic blood pressure/diastolic blood pressure higher than or equal to age-and-height-specific 90th percentile; triglycerides (TG) ≥110 mg/dL; high-density lipoprotein ≤50 mg/dL (females) and ≤40 mg/dL (males), or glucose ≥110 mg/dL. Students from University of Chiapas Medical School applied a questionnaire to evaluate food frequency, a 24h recall and a questionnaire addressing food intake patterns and physical activity.
Results. According to the used criteria overall prevalence of MS was 16.0 %. Prevalence of overweight and obesity, triglycerides (TG) and MS increased with HOMA-IR quartiles increments. Carbohydrates, dietary fiber, fat and protein consumption, as well as PA, were not associated with obesity, HOMA-IR, neither MS. However, eating out of home more than five times per week was associated (p‹0.006) with obesity and MS, and postprandial napping was associated (p‹0.03) with HOMA-IR.
Conclusions. High prevalence of overweight and obesity among teenagers was directly associated with high prevalence of MS in this study. Eating outside home and postprandial napping were associated to obesity, MS and HOMA-IR.
