ABSTRACT
OBJETIVOS: Conocer si en nuestro medio la duración del sueño y el patrón de distribución del sueño a lo largo del día en < 2 años son similares a los publicados. Obtener información sobre la prevalencia de las alteraciones de la duración del sueño y sobre la influencia de la edad en dicha prevalencia. MATERIAL Y MÉTODOS: Estudio observacional, descriptivo, transversal realizado en niños < 2 años de 3 centros de salud de León y Asturias. Mediante la cumplimentación por sus padres del cuestionario de sueño Brief Infant Sleep Questionnaire (BISQ) se analizó la duración del sueño. Para evaluar alteraciones en la duración del sueño se utilizaron percentiles de duración del sueño. Los resultados fueron valorados en el conjunto de niños encuestados y en los 2 grupos creados para su comparación (niños > y < 6 meses) (niños de León y Asturias). RESULTADOS: Se incluyeron 125 niños < 2 años (73 varones). El sueño nocturno aumentó desde 8,28 ± 2,06 h en < 6 meses hasta 10,43 ± 1,21 en > 6 meses (p = 0,0001), disminuyendo el sueño diurno desde 4,61 ± 2,66 a 1,96 ± 0,79 h (p = 0,0001). Los niños leoneses duermen durante el día más horas que los asturianos (3,91 ± 2,67 vs 3,00 ± 2,09 h, p = 0,041). Diecinueve niños tuvieron una duración total de sueño < percentil 2, siendo más frecuente en niños < 6 meses (14/72 vs 5/53, p = 0,006). CONCLUSIONES: Los niños sustituyen el sueño diurno por el sueño nocturno según van creciendo. Aproximadamente el 15% de niños < 2 años podría tener trastornos en la duración del sueño, siendo este hallazgo más frecuente en < 6 meses
OBJECTIVES: The aim is to study the sleep duration and the 24-hour sleep distribution pattern in children under 2 years-old from two different areas of Spain, as well as to determine the prevalence of abnormal sleep duration and the influence of age on this prevalence, and compare them with the already published data. MATERIAL AND METHODS: An observational, descriptive and cross-sectional study on children from two health centers: one in Castilla y León and the other in Asturias. Their parents completed the Brief Infant Sleep Questionnaire (BISQ). Daytime and nighttime sleep duration was assessed, with percentiles being used to evaluate the results. Two groups were created: one according to the age (children under or above 6 months), and the other according to the area. RESULTS: A total of 125 children were studied (73 males). The nighttime sleep duration increased from 8.28 ± 2.06 hours to 10.43 ± 1.21 hours (P = .0001) and the daytime sleep decreased from 4.61 ± 2.66 to 1.96 ± 0.79 hours (P = .0001) for children under 6 months and above 6 months, respectively. The children from Castilla y León slept more during daytime than those from Asturias (3.91 ± 2.67 vs 3.00 ± 2.09 hours, P = .041). Nineteen children had a total sleep duration below the 2 nd percentile. A sleep duration below normal percentiles was observed in children under 6 months (14/72 vs 5/53, P = .006). CONCLUSIONS: As children grow older, they substitute daytime sleep for nighttime sleep. Approximately 15% of the children under 2 years-old may have changes in sleep duration, and is more common in children under 6 months
