| Popis: | espanolIntroduccion: la restriccion del sueno nocturno tiene efectos inmediatos, como la presencia de somnolencia diurna excesiva, fatiga general o alteraciones en la concentracion; a largo plazo, aumenta el riesgo de muerte por trastornos cardiacos, respiratorios y metabolicos, y aumenta la prevalencia de la obesidad en las poblaciones sanas. Sin embargo, a pesar de la existencia de una gran cantidad de estudios, los resultados siguen siendo controvertidos. Objetivo: discutir y analizar la evidencia sobre la restriccion parcial del sueno frente al sueno habitual y su efecto en la ingesta dietetica de energia, incluyendo comidas especificas, asi como en las concentraciones de ghrelina y leptina en una poblacion sana. Metodos: se realizo una busqueda electronica de la literatura entre octubre de 2016 y febrero de 2019 en PubMed, Scopus, Lilacs y Embase. Los terminos utilizados fueron “sleep”, “feeding behavior”, “dietary energy intake”, “energy intake”, “meal”, “ghrelin” y “leptin”. Resultados: la busqueda bibliografica identifico 384 articulos potenciales. De un total de 8 articulos aceptados en la revision, 6 tenian informacion disponible para el analisis de la ingesta total de energia. El resultado general mostro una diferencia significativa en la ingesta de energia (149,86 (IC 95 %: 10,09-289,63); p = 0,04) y una mayor ingesta de todos los macronutrientes. Conclusiones: la presente revision sistematica y meta-analisis indico que la restriccion del sueno aumenta la ingesta total de energia, asi como la de todos los macronutrientes, en comparacion con el sueno habitual. EnglishBackground: the restriction of nocturnal sleep has immediate effects, including the presence of excessive daytime sleepiness, general fatigue, or impaired concentration. In the long term, it increases the risk of death from cardiac, respiratory, and metabolic disorders, and the prevalence of obesity in healthy populations. However, despite the existence of a large number of studies on this topic, results have been controversial. Objective: to discuss and analyze the evidence on the effects of nocturnal sleep restriction versus habitual sleep on dietary energy intake, including specific meals, as well as the relationship between ghrelin and leptin levels in a healthy population. Methods: a systematic search of the literature was conducted in October 2016 and February 2019 using the PubMed, Scopus, Lilacs, and Embase databases. Terms used were “sleep,” “feeding behavior,” “dietary energy intake,” “energy intake,” “meal,” “ghrelin,” and “leptin.” Results: the bibliographic search identified 384 potential articles. Of a total of eight articles accepted in the review, six contain information available for the analysis of total energy intake. The overall result shows a significant difference in energy intake between study groups (149.86 (95 % CI: 10.09-289.63); p = 0.04), and a higher intake of all macronutrients. Conclusions: the present systematic review and meta-analysis demonstrated that partial sleep deprivation increases total energy intake, as well as all macronutrients, when compared to habitual sleep. |
