Introducción. Estudios mayoritariamente en adultos han mostrado una asociación entre cantidad de sueño y obesidad. Objetivo. Determinar si existe una asociación entre la privación de sueño nocturno durante la semana y el fin de semana, los hábitos alimentarios y la actividad física con el estado nutricional en escolares chilenos. Población, material y métodos. Estudio transversal. En estudiantes de 6 a 11 años, se realizó la evaluación antropométrica; a sus padres se les aplicó la encuesta de sueño de Pittsburg para evaluar la calidad de sueño de su hijo y se consultó sobre hábitos alimentarios y actividad física. Resultados. Se evaluaron 1810 escolares de ambos sexos, pertenecientes a escuelas públicas de Santiago. El 49,9% de los escolares dormía menos de lo recomendado en la semana. Se observó una asociación en el modelo crudo (OR crudo 1,82; IC 95%: 1,29-2,56), el modelo 2 ajustado por bebidas cola (OR 1,83; IC 95%: 1,30-2,59) y el modelo 3 ajustado por consumo de cena, bebidas cola, bebidas con cafeína y nicturia (OR 1,85; IC 95%: 1,30-2,62). Se observó que realizar ejercicios era un factor protector frente al sobrepeso y la obesidad; en cambio, presentar movimientos de piernas durante la noche era un factor de riesgo. Conclusiones. Hay una asociación entre menos horas de sueño e incremento del riesgo de sobrepeso/obesidad en la muestra estudiada.
Introduction. Studies mainly performed in adults have shown an association between the amount of sleep and obesity. Objective. To determine if there is an association between nocturnal sleep deprivation during the week and the weekend, eating habits, physical activity and nutritional status among Chilean schoolchildren. Population, Material and Methods. Crosssectional study. An anthropometric assessment was done among 6-11 year-old students; the Pittsburgh Sleep Quality Index (PSQI) was used among parents to measure their children's quality of sleep; they were asked about eating habits and physical activity. Results. One thousand eight hundred and ten schoolchildren of both sexes, attending public schools in Santiago, were assessed. Out of these schoolchildren, 49.9% slept fewer hours per night than recommended. An association in the crude model (crude OR 1.82; CI 95%: 1.29-2.56), in model 2 adjusted for cola drinks (OR 1.83; CI 95%: 1.30-2.59) and in model 3 adjusted for dinner, cola drink and caffeine beverage consumption and nocturia (OR 1.85; CI 95%: 1.30-2.62) was observed. It was also noticed that exercising was a protective factor against overweight and obesity; however, periodic limb movement during sleep was a risk factor. Conclusions. This study showed an association between fewer hours of sleep and an increase in the risk of overweight/obesity.
