背景
睡眠不佳是抑郁症的一个风险因素，但对其潜在机制知之甚少。
目的
通过经验取样法（ESM）深入到个体主观睡眠和情感的日常生活模式的“微观层面”，理清睡眠与抑郁症相关的潜在机制。
方法
一个由553名女性组成的基于人群的双胞胎样本接受了为期5天的基线ESM方案，该方案评估主观睡眠和情感以及对抑郁症的四次随访评估。
结果
睡眠与次日的情感有关，尤其是积极情感。白天的消极情感与随后的夜间睡眠无关。基线睡眠可预测随访期间的抑郁症状。
结论
睡眠对日常情感的微妙、反复的影响，而非情感对睡眠的微妙、反复的影响，可能是女性患抑郁症途径中的因素之一。
BackgroundPoor sleep is a risk factor for depression, but little is known about the underlying mechanisms.AimsDisentangling potential mechanisms by which sleep may be related to depression by zooming down to the 'micro-level' of within-person daily life patterns of subjective sleep and affect using the experience sampling method (ESM).MethodA population-based twin sample consisting of 553 women underwent a 5-day baseline ESM protocol assessing subjective sleep and affect together with four follow-up assessments of depression.ResultsSleep was associated with affect during the next day, especially positive affect. Daytime negative affect was not associated with subsequent night-time sleep. Baseline sleep predicted depressive symptoms across the follow-up period.ConclusionsThe subtle, repetitive impact of sleep on affect on a daily basis, rather than the subtle repetitive impact of affect on sleep, may be one of the factors on the pathway to depression in women.
