Screening of Metabolic Syndrome in Obese Children: A Primary Care Concern
2009
Objective: To determine the prevalence of metabolic syndrome (MS) in a primary care pediatric setting and to collect clinical and biochemical data, allowing for a prediction of its presence in a supposedly healthy population. Methods: Belonging to a pediatric population followed by pediatricians of the Italian National Health Service, 415 subjects with obesity as a unique selection criterion were enrolled. The entire cohort was screened for MS, which was defined as the presence of at least 2 other findings out of obesity: fasting hyperglycemia, low levels of high-density lipoproteins cholesterol, hypertriglyceridemia, and hypertension. Results: The overall prevalence of MS was 30.8%. Major findings (out of obesity) were low high-density lipoproteins cholesterol levels (46.2%), hypertension (23.6%), hypertriglyceridemia (22.2%), and fasting hyperglycemia (16.6%). Waist-to-height ratio was the only clinical parameter directly related to MS, with the same predictive power of insulin resistance. Conclusions: Metabolic syndrome can be present in a significant percentage of “healthy” obese children, and a simple clinical parameter could identify at-risk subjects. This observation justifies the development and implementation of pediatric networks for obesity screening programs.
