Circadian misalignment and disrupted rest-activity rhythms have been linked to adverse health and educational outcomes, yet few studies have considered their relationships with economic outcomes. We investigate associations between multiple accelerometer-measured circadian misalignment traits (Composite Phase Deviation and the Sleep Regularity Index) and rest-activity rhythm traits (Inter-daily Stability, Intra-daily variability and relative amplitude), with occupational attainment, measured using the average wage paid to an individual's occupation. We use data from 20 356 UK Biobank participants who wore an accelerometer (2013-16), provided employment data for the year they wore the accelerometer, and supplied covariate data at recruitment (2006-10). We use linear regression, with incremental adjustments for four sets of covariates, and stratify our analysis by sex. Our findings provide mixed evidence on the relationship between circadian misalignment and occupational attainment, varying by the measure of circadian misalignment used, and sex. We find fragmented rest-activity rhythms to be associated with higher occupational attainment, which is counterintuitive. Since circadian misalignment is a modifiable trait, our results suggest potential benefits of policies aimed at reducing circadian misalignment, such as altering work schedules and reducing bright light exposure in the evening. Further research is needed to elucidate the mechanisms through which rest-activity rhythms may impact economic outcomes.
昼夜节律失调和休息-活动节奏紊乱与不良健康和教育结果有关，但很少有研究考虑它们与经济结果之间的关系。我们调查了通过加速度计测量的多种昼夜节律失调特征（综合相位偏差和睡眠规律指数）以及休息-活动节奏特征（日间稳定性、日内变异性和相对振幅）与职业成就之间的关联，职业成就通过个人职业的平均工资来衡量。我们使用了来自20356名英国生物银行参与者的数据，这些参与者佩戴了加速度计（2013 - 2016年），提供了佩戴加速度计当年的就业数据，并在招募时（2006 - 2010年）提供了协变量数据。我们使用线性回归，对四组协变量进行逐步调整，并按性别分层分析。我们的研究结果为昼夜节律失调与职业成就之间的关系提供了混合证据，这因所使用的昼夜节律失调测量方法和性别而异。我们发现碎片化的休息-活动节奏与更高的职业成就相关，这是违反直觉的。由于昼夜节律失调是一个可改变的特征，我们的结果表明旨在减少昼夜节律失调的政策可能带来潜在益处，例如改变工作时间表和减少夜间强光暴露。需要进一步研究以阐明休息-活动节奏可能影响经济结果的机制。
