Triglycerides and high-density lipoprotein cholesterol are associated with insulinemia in adolescents.

Objective: The aim of this study was to evaluate the association between lipids and insulin concentration in adolescents.

Material And Methods: A cross-sectional study of 350 adolescents aged 14-19 years old from a public high school in Guadalajara, in the state of Jalisco, Mexico, was conducted. Fasting insulin concentration was determined using microparticle enzyme immunoassay; total cholesterol and triglycerides were detected by standard enzymatic procedures;and low- and high-density lipoproteins were found using standard precipitation methods. Statistical analysis included linear multivariate regression.

Results: Serum triglycerides were associated positively with insulin fasting (beta = 0.003, p = 0.0001) and high-density lipoprotein cholesterol was negatively associated with insulin fasting in male adolescents 18-19 years old (beta = -0.03, p = 0.012).

Conclusions: The relationships between triglycerides and insulin and between high-density lipoprotein cholesterol and insulin are already present in adolescence.
