最近的研究表明，与年轻人相比，老年人可能不太容易受到酒精第二天的影响。酒精对年轻人的影响可能是由睡眠持续时间介导的，但由于饮酒情况的年龄差异，这种介导过程可能不适用于老年人。本研究调查了年龄组（年轻人与老年人）在日常生活中饮酒如何影响第二天疲劳的差异。使用多层次、有调节的中介框架对 91 名年轻人（年龄 20-31 岁）和 75 名老年人（年龄 65-80 岁）在约 101 天中获得的饮酒量、睡眠时间和第二天疲劳程度的报告进行了建模。研究结果表明：(1) 仅在年轻人中，比平时更多地饮酒与比平时更疲劳有关； (2) 仅在年轻人中，比平常饮酒量多与睡眠时间比平常短相关； (3) 年轻人和老年人的睡眠时间比平常短都与更疲劳有关。对于典型的年轻人来说，饮酒和第二天疲劳之间的很大一部分（43%）可以通过假设通过睡眠时间进行调节来解释，而对于典型的老年人来说，没有证据表明有调节作用。酒精使用、睡眠和疲劳之间的中介过程中的年龄差异的发现，为了解最近观察到的老年人相对于年轻人酒精第二天影响减少的机制提供了见解。
Recent work suggests that older adults may be less susceptible to the next-day effects of alcohol relative to younger adults. The effects of alcohol in younger adults may be mediated by sleep duration but, due to age differences in the contexts of alcohol use, this mediation process may not generalize to older adults. The present study examined age group (younger versus older adults) differences in how alcohol use influenced next-day tiredness during daily life. Reports of alcohol use, sleep duration, and next-day tiredness obtained on ~101 days from 91 younger adults (age 20–31 years) and 75 older adults (age 65–80 years) were modeled using a multilevel, moderated mediation framework. Findings indicate that (1) Greater than usual alcohol use was associated with greater than usual tiredness in younger adults only; (2) greater than usual alcohol use was associated with shorter than usual sleep duration in younger adults only; and (3) shorter than usual sleep duration was associated with greater tiredness in both younger and older adults. For the prototypical younger adult, a significant portion (43%) of the association between alcohol use and next-day tiredness could be explained assuming mediation through sleep duration, while there was no evidence of mediation for the prototypical older adult. Findings of age differences in the mediation process underlying associations among alcohol use, sleep, and tiredness provide insight into the mechanisms driving recent observations of reduced next-day effects of alcohol in older relative to younger adults.
