Sleep duration changes across the life course and differs by education in the United States. However, little research has examined whether educational differences in sleep duration change over age-or whether sleep duration trajectories over age differ by education. This study uses a life course approach to analyze American Time Use Survey data (N = 60,908), examining how educational differences in weekday sleep duration change from middle to older adulthood (ages 40-79). For men only, differences in total sleep time between individuals with less than a high school degree and those with more education converge in older adulthood. Results suggest that this leveling is explained by decreasing educational stratification in work hours as men enter older adulthood. Findings highlight the importance of employment for shaping gendered socioeconomic differences in sleep and demonstrate differences by education in how sleep duration changes over age, with possible implications for health disparities.

从中年到老年受教育程度不同的睡眠持续时间差异：就业分层是否有助于性别平等？

在美国，睡眠时间在整个生命过程中会发生变化，并且因教育程度而异。然而，很少有研究探讨睡眠持续时间的教育差异是否随年龄变化，或者睡眠持续时间轨迹随年龄变化是否因教育而不同。本研究采用生命历程方法来分析美国时间使用调查数据 (N = 60,908)，研究工作日睡眠时间的教育差异如何从中年到老年（40-79 岁）变化。仅就男性而言，高中学历以下的人和受过高等教育的人之间的总睡眠时间差异在成年后趋于一致。结果表明，随着男性进入老年，工作时间的教育分层减少可以解释这种均衡化。研究结果强调了就业对于塑造睡眠方面的性别社会经济差异的重要性，并通过教育证明了睡眠时间如何随年龄变化的差异，这可能对健康差异产生影响。
