          Abstract

          Abstract Introduction: 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.

          Resumen Introducción: la restricción del sueño nocturno tiene efectos inmediatos, como la presencia de somnolencia diurna excesiva, fatiga general o alteraciones en la concentración; a largo plazo, aumenta el riesgo de muerte por trastornos cardíacos, respiratorios y metabólicos, 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 restricción parcial del sueño frente al sueño habitual y su efecto en la ingesta dietética de energía, incluyendo comidas específicas, así como en las concentraciones de ghrelina y leptina en una población sana. Métodos: se realizó una búsqueda electrónica de la literatura entre octubre de 2016 y febrero de 2019 en PubMed, Scopus, Lilacs y Embase. Los términos utilizados fueron “sleep”, “feeding behavior”, “dietary energy intake”, “energy intake”, “meal”, “ghrelin” y “leptin”. Resultados: la búsqueda bibliográfica identificó 384 artículos potenciales. De un total de 8 artículos aceptados en la revisión, 6 tenían información disponible para el análisis de la ingesta total de energía. El resultado general mostró una diferencia significativa en la ingesta de energía (149,86 (IC 95 %: 10,09-289,63); p = 0,04) y una mayor ingesta de todos los macronutrientes. Conclusiones: la presente revisión sistemática y meta-análisis indicó que la restricción del sueño aumenta la ingesta total de energía, así como la de todos los macronutrientes, en comparación con el sueño habitual.

              Brief communication: Sleep curtailment in healthy young men is associated with decreased leptin levels, elevated ghrelin levels, and increased hunger and appetite.

              Total sleep deprivation in rodents and in humans has been associated with hyperphagia. Over the past 40 years, self-reported sleep duration in the United States has decreased by almost 2 hours. To determine whether partial sleep curtailment, an increasingly prevalent behavior, alters appetite regulation. Randomized, 2-period, 2-condition crossover clinical study. Clinical Research Center, University of Chicago, Chicago, Illinois. 12 healthy men (mean age [+/-SD], 22 +/- 2 years; mean body mass index [+/-SD], 23.6 +/- 2.0 kg/m2). Daytime profiles of plasma leptin and ghrelin levels and subjective ratings of hunger and appetite. 2 days of sleep restriction and 2 days of sleep extension under controlled conditions of caloric intake and physical activity. Sleep restriction was associated with average reductions in the anorexigenic hormone leptin (decrease, 18%; P = 0.04), elevations in the orexigenic factor ghrelin (increase, 28%; P < 0.04), and increased hunger (increase, 24%; P < 0.01) and appetite (increase, 23%; P = 0.01), especially for calorie-dense foods with high carbohydrate content (increase, 33% to 45%; P = 0.02). The study included only 12 young men and did not measure energy expenditure. Short sleep duration in young, healthy men is associated with decreased leptin levels, increased ghrelin levels, and increased hunger and appetite.
