ASSOCIATED FACTORS TO INSULIN VALUES IN A POPULATION-BASED STUDY IN ADOLESCENTS

Objectives: To identify factors that correlate with insulin values and to examine its independent associations among adolescents. Methods: A cross-sectional population-based study was conducted among adolescents aged 12-16,9 years old. A multi-stage stratified cluster random sampling method was employed. Anthropometric measurements and nutritional survey were performed, and fasting blood samples for insulin were obtained. Statistics: Multiple lineal regression. Results: 379 adolescents were included. Mean age was 14.08 +/- 1.30 years. Factors associated with higher fasting insulin levels were puberty [beta 4.55 (95% IC 0.42-8.69)], abdominal obesity [beta 6.11 (95% IC 3.93-8.29)] and to be born small for gestational age (SGA) [beta 7.45 (95% IC 2.47-12.44)]. It was observed a negative association between the regular intake of olive oil at home and insulin values [beta -4.14(95% IC -7.31- -0.98)]. Conclusions: Abdominal obesity and SGA were factors associated with higher fasting insulin values. In contrast, the regular intake of olive oil at home was an independent protective factor.
