Background

The present study investigated the association between two domains of physical activity (occupational physical activity [OPA] and leisure-time physical activity [LTPA]) and sleep duration.

Methods

We investigated 3,421 paid workers from the Korea National Health and Nutrition Examination Survey, 2014–2015. Sleep duration was categorized into three categories (short for less than 5 h, optimal for 5–9 h, and long for more than 9 h). OPA and LTPA were defined in terms of answers to relevant questions. Odds ratios were calculated for sleep duration according to each physical activity domain using multinomial logistic regression models.

Results

There were 464 subjects (13.6%) who showed short sleep duration, and 169 subjects (4.9%) who showed long sleep duration. Prevalence of OPA and LTPA was higher in male workers than in female workers (for OPA: 3.67% and 1.76%, respectively, p = 0.0108; for LTPA: 16.14% and 6.07%, respectively, p < 0.0001). The odds ratio of OPA for long sleep duration in female workers was 3.35 (95% confidence interval, 1.37–8.21). Otherwise, LTPA was not associated with sleep duration in female paid workers, nor both physical activity domains in male paid workers.

Conclusion

Female paid workers with work-related physical activity were at risk of oversleeping. These findings also suggested that physical activity has distinct associations with sleep duration according to the physical activity domains and sex.

工作人群中异常睡眠时间与职业和休闲时间身体活动的关联：一项基于全国人口的研究

背景

本研究调查了身体活动的两个领域（职业身体活动 [OPA] 和休闲时间身体活动 [LTPA]）与睡眠时间之间的关联。

方法

我们调查了 2014-2015 年韩国国家健康和营养调查中的 3,421 名带薪工人。睡眠时间分为三类（短于 5 小时，最佳 5-9 小时，长于 9 小时）。OPA 和 LTPA 是根据对相关问题的回答来定义的。使用多项逻辑回归模型根据每个身体活动域计算睡眠持续时间的优势比。

结果

有 464 名受试者 (13.6%) 显示睡眠时间短，169 名受试者 (4.9%) 显示睡眠时间长。男性工人的 OPA 和 LTPA 患病率高于女性工人（OPA 分别为 3.67% 和 1.76%，p  = 0.0108；LTPA 分别为 16.14% 和 6.07%，p  < 0.0001）。女性工人长时间睡眠的 OPA 优势比为 3.35（95% 置信区间，1.37-8.21）。否则，LTPA 与女性有薪工人的睡眠时间无关，也与男性有薪工人的两个身体活动领域无关。

结论

从事与工作相关的体力活动的女性带薪工人有睡过头的风险。这些发现还表明，根据身体活动领域和性别，身体活动与睡眠时间有明显的关联。
