Background/aims: Ethnic-based associations between obesity and the metabolic syndrome (MS) have been suggested. The prevalence of MS in obese children was found to range between 13.9 and 48.8%, depending on the country of origin. This study was conducted to investigate the relationship between obesity and various components of MS in prepubertal children in Lebanon.
Methods: Eighty-seven obese children (Tanner stage 1), 25 overweight and 28 normal-weight controls were recruited from private and public schools. Anthropometric, biochemical and blood pressure measurements were performed.
Results: According to the modified Adult Treatment Panel III definition, the MS was identified in 26.4 and 4% of obese and overweight children, respectively, with a higher prevalence among girls than boys. The most common abnormalities among subjects with MS were elevated waist circumference (WC) (100.0%), high triglyceride (91.7%) and low high-density lipoprotein cholesterol (66.7%) levels. Insulin resistance was identified in 70% of obese children and 75% of those having the MS. Body mass index, WC and homeostasis model assessment of insulin resistance were significant determinants of the MS in this age group.
Conclusion: MS was found in 26.4% of obese Lebanese children, thus underscoring the importance of early screening of obesity and its associated metabolic abnormalities and of developing successful multicomponent interventions addressing pediatric obesity and MS.
