Sleep disturbances are commonly reported in working populations. While research has identified various work-related risk factors for poor sleep, the relationship between prior occupational physical activity (OPA) and future sleep disturbances remains unclear. The study aimed to examine the prospective associations between OPA levels and sleep disturbances in adults.
We utilized longitudinal data from the MJ cohort study (1998 to 2022). The sample (N = 62528) consisted of adults aged 18 years or above. The mean age (in years) was 35.9 (SD = 9.5), and they were working full-time and reported no sleep disturbances at baseline. We examined the prospective associations between self-reported OPA levels (light, moderate, moderately heavy, and heavy) at baseline, and the presence of sleep disturbances at a mean follow-up time of 5.6 years (SD = 4.5). Cox proportional hazard models were conducted, adjusting for potential confounding variables.
Using light OPA level as the reference group, individuals with moderately heavy OPA (HR: 1.13, 95% CI: 1.07, 1.19, p < 0.001) and heavy OPA (HR: 1.22, 95% CI: 1.11, 1.34, p < 0.001) at baseline had a higher risk of sleep disturbances at follow-up. Stratified analyses showed that the association between higher levels of OPA and sleep disturbances remained across different subgroups. Notably, these associations were more pronounced among females (p = 0.008), for moderately heavy OPA (HR: 1.23, 95% CI: 1.12, 1.35, p < 0.001) and heavy OPA (HR: 1.45, 95% CI: 1.10, 1.91, p = 0.009). These associations were also more pronounced in certain occupational groups (p = 0.003), where only heavy OPA was significantly associated with an elevated risk of sleep disturbances among civil servants (HR: 1.66, 95% CI: 1.08, 2.55, p = 0.020) and office workers, professionals and technicians (HR: 1.49, 95% CI: 1.09, 2.05, p = 0.010).
Higher OPA levels were associated with an increased risk of sleep disturbances. Workplace support or interventions are in need to improve sleep patterns.
工作人群中普遍存在睡眠障碍的报告。虽然研究已经确定了各种与工作相关的睡眠不佳风险因素，但既往职业体力活动（OPA）与未来睡眠障碍之间的关系仍不明确。本研究旨在探讨成年人OPA水平与睡眠障碍之间的前瞻性关联。
我们利用了MJ队列研究（1998年至2022年）的纵向数据。样本（N = 62528）由18岁及以上的成年人组成。平均年龄（岁）为35.9（标准差 = 9.5），他们全职工作，且在基线时报告无睡眠障碍。我们研究了基线时自我报告的OPA水平（轻度、中度、中度重度和重度）与平均随访时间5.6年（标准差 = 4.5）时睡眠障碍的存在之间的前瞻性关联。进行了Cox比例风险模型分析，并对潜在的混杂变量进行了调整。
以轻度OPA水平作为参照组，基线时中度重度OPA（风险比：1.13，95%置信区间：1.07，1.19，p < 0.001）和重度OPA（风险比：1.22，95%置信区间：1.11，1.34，p < 0.001）的个体在随访时出现睡眠障碍的风险更高。分层分析表明，不同亚组中较高的OPA水平与睡眠障碍之间的关联仍然存在。值得注意的是，这些关联在女性中更为明显（p = 0.008），对于中度重度OPA（风险比：1.23，95%置信区间：1.12，1.35，p < 0.001）和重度OPA（风险比：1.45，95%置信区间：1.10，1.91，p = 0.009）。这些关联在某些职业群体中也更为明显（p = 0.003），其中只有重度OPA与公务员（风险比：1.66，95%置信区间：1.08，2.55，p = 0.020）以及办公室职员、专业人员和技术人员（风险比：1.49，95%置信区间：1.09，2.05，p = 0.010）睡眠障碍风险升高显著相关。
较高的OPA水平与睡眠障碍风险增加有关。需要工作场所的支持或干预措施来改善睡眠模式。
