^les^aObjetivo: Analizar los factores asociados con insulinemia en ayunas en población general adolescente. Métodos: Estudio epidemiológico observacional sobre una muestra poblacional de adolescentes (12-16,9 años) seleccionados mediante muestreo probabilístico polietápico. Se realizaron examen físico, antropometría, encuesta nutricional y se determinó insulinemia en ayunas. Estadística: regresión lineal múltiple. Resultados: Se incluyeron 379 adolescentes con edad media 14,08 ± 1,30 años. Se relacionaron con mayores cifras de insulinemia el desarrollo puberal [β 4,55 (95% IC 0,42-8,69)], obesidad abdominal [β 6,11(95% IC 3,938,29)] y el antecedente de bajo peso para la edad gestacional (BPEG) [β 7,45 (95% IC 2,47-12,44)]. El consumo habitual de aceite de oliva en domicilio mostró una relación inversa con las cifras de insulinemia [β -4,14 (95% IC -7,31- -0,98)]. Conclusión: Los factores de riesgo asociados a mayores cifras de insulinemia en ayunas fueron la obesidad abdominal y el antecedente de BPEG. El consumo habitual de aceite de oliva en domicilio fue un factor protector.^len^aObjectives: 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.
