Relación entre Índice de Masa Corporal con trastornos del sueño en adolescentes escolares

Background: Sleep disorder is related to different factors such as body mass index. Inadequate and/or insufficient sleep can cause obesity and trigger the presence of various cardiometabolic diseases at an early age. To verify the relationship between sleep disorders with the BMI Body Mass Index of adolescents of both sexes, and to compare the BMI and sleep disorder values with the reference values for Chile. Methods: A descriptive cross-sectional (correlational) study was conducted in 119 adolescents (69 men and 50 women) with an age range of 16 to 17 years. Weight, height, and BMI were calculated. Sleep disorders were assessed with a self-perception scale of 24 questions. Results: There was a positive correlation between sleep disorders and BMI (men r= 0.13, p<0.05, and in women r= 0.16, p<0.05). There were no differences in BMI with the Chilean reference; variations were minimal (between 0.03 to 1.61kg/m2 in both sexes). In sleep disorders, the adolescents in the study obtained significantly higher scores than the Chilean reference (ranging from 15.3 to 17.5 points). Conclusions: Sleep disorders seem to be related to the increase in BMI and/or vice versa, this could play an important role for the development of obesity among young people.
