Abstract: (5491 Views)
Background: No evidence exists regarding the prevalence of the hypertriglyceridemic waist phenotype in adolescents. We aimed to evaluate the prevalence of this phenotype in a representative sample of Tehranian adolescents.
Materials and Methods: Anthropometry and biochemical measurement were assessed in a population-based cross-sectional study of 3036 Tehranian adolescents (1413 male and 1623 female) aged 10-19 years. Hypertriglyceridemic waist phenotype was defined as concurrently having serum triglyceride concentration ≥110 mg/dl and waist circumference ≥90th percentile for age and sex. Overweight (≥95th percentile) and at risk for overweight (≥85th-<95th percentile) was defined based on the standardized percentile curves of body mass index suggested for Iranian adolescents.
Results: The prevalence of the hypertriglyceridemic waist phenotype was 6.4% (95%CI: 5.5-7.2) among Tehranian adolescents (males: 7.3%, 5.9-8.7 and females: 5.6%, 4.4-6.7). Overweight subjects had the highest proportion of hypertriglyceridemic waist phenotype than those at risk for overweight and those with normal-weight (male: 42.9 vs 2.9 and 0.0%, respectively, P<0.01 female: 32.5 vs 11.3 and 1.3%, respectively, P<0.01).
Conclusion: This study provides evidence showing high prevalence of the hypertriglyceridemic waist phenotype in Tehranian adolescents, particularly among overweight adolescents. This finding highlights the need for effective preventive and therapeutic strategies relying on diet, physical activity and lifestyle modification.
