GALERA MARTINEZ, Rafael et al. Associated factors to insulin values in a population-based study in adolescents. Nutr. Hosp. [online]. 2013, vol.28, n.5, pp.1610-1614. ISSN 1699-5198.

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 [β 4.55 (95% IC 0.42-8.69)], abdominal obesity [β 6.11 (95% IC 3.93-8.29)] and to be born small for gestational age (SGA) [β 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 [β -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.
