The aim was to investigate the effect of sleep improvement on desire for and intake of weight gain-promoting foods in adolescents with late bedtimes.
A sample of 42 adolescents with late bedtimes was enrolled in an intervention designed to improve sleep. Their desire for and intake of food in the morning was assessed at before and after treatment.
Adolescents with earlier bedtimes at post-treatment relative to pretreatment increased their caloric intake of low glycemic index, fruit, and dairy foods at post-treatment. This effect was not observed in adolescents who did not improve their bedtime at post-treatment.
These findings suggest that advancing bedtimes earlier can improve breakfast choices, an important meal for obesity prevention during adolescence.
旨在研究改善睡眠对晚睡青少年摄入促进体重增加食物的欲望及摄入量的影响。
招募了42名晚睡青少年样本,参与一项旨在改善睡眠的干预措施。在治疗前后评估他们早晨对食物的欲望及摄入量。
与治疗前相比,治疗后就寝时间提前的青少年在治疗后增加了低血糖指数食物、水果和奶制品的热量摄入。在治疗后就寝时间未改善的青少年中未观察到这种效果。
这些发现表明,提前就寝时间可以改善早餐选择,而早餐是预防青少年肥胖的一顿重要餐食。
