To examine the associations between occupation, sleep duration and sleep quality.
The data for this study was extracted from data collected from the 2008 Chinese Sub-optimal Health Study. Our study sample consisted of 18,316 Chinese subjects aged 18-65. Occupation and other relevant characteristics to sleep were collected. We used the Pittsburgh Sleep Quality Index (PSQI) to measure sleep quality and multiple logistic regression models to examine the association of occupation with shortened sleep duration and poor sleep quality.
Farmers had the longest sleep duration (mean=8.22 hours) while the civil servants had the shortest sleep duration (mean=7.85 hours). Farmers also had the best sleep quality (mean score=3.74) while professional workers had the worst sleep quality (mean score=4.87). Compared to civil servants, the OR of shortened sleep duration and poor sleep quality for blue collar workers is 1.39 (95%CI: 1.11-1.73) and 1.28 (95%-CI: 1.15-1.42), respectively, after adjusting for age, sex, marital status, education, area, smoking, drinking, pain, and health status.
sleep duration and quality varied among different Chinese occupation populations. The blue collar workers are more likely to have shortened sleep duration and poor sleep quality.
探讨职业、睡眠时间与睡眠质量之间的关联。
本研究数据取自2008年中国亚健康研究收集的数据。我们的研究样本包括18316名年龄在18至65岁之间的中国受试者。收集了职业及其他与睡眠相关的特征。我们使用匹兹堡睡眠质量指数（PSQI）来衡量睡眠质量，并使用多元逻辑回归模型来检验职业与睡眠时间缩短和睡眠质量差之间的关联。
农民的睡眠时间最长（平均 = 8.22小时），而公务员的睡眠时间最短（平均 = 7.85小时）。农民的睡眠质量也最好（平均得分 = 3.74），而专业人员的睡眠质量最差（平均得分 = 4.87）。在调整年龄、性别、婚姻状况、教育程度、地区、吸烟、饮酒、疼痛和健康状况后，与公务员相比，蓝领工人睡眠时间缩短和睡眠质量差的比值比分别为1.39（95%置信区间：1.11 - 1.73）和1.28（95%置信区间：1.15 - 1.42）。
不同职业的中国人群睡眠时间和质量存在差异。蓝领工人更有可能出现睡眠时间缩短和睡眠质量差的情况。
