Though various factors related to fluctuations in sleep duration have been identified, information remains limited regarding the correlates of short and long sleep duration among the Korean population. Thus, we investigated characteristics that could be associated with short and/or long sleep duration among middle-aged and elderly Koreans. A total of 84,094 subjects (27,717 men and 56,377 women) who participated in the Health Examinees Study were analyzed by using multinomial logistic regression models. To evaluate whether sociodemographic factors, lifestyle factors, psychological conditions, anthropometry results, and health conditions were associated with short and/or long sleep duration, odds ratios (ORs) and 95% confidence intervals (CIs) were estimated with sleep duration of 6-7 hours as the reference group, accounting for putative covariates. Regardless of sexual differences, we found that adverse behaviors and lifestyle factors including low educational attainment, unemployment, being unmarried, current smoking status, lack of exercise, having irregular meals, poor psychosocial well-being, frequent stress events, and poor self-rated health were significantly associated with abnormal sleep duration. Similarly, diabetes mellitus and depression showed positive associations with abnormal sleep duration in both men and women. Our findings suggest that low sociodemographic characteristics, adverse lifestyle factors, poor psychological conditions, and certain disease morbidities could be associated with abnormal sleep duration in middle-aged and elderly Koreans.
尽管已经确定了与睡眠时间波动相关的各种因素，但关于韩国人群中短睡眠时间和长睡眠时间的相关因素的信息仍然有限。因此，我们调查了韩国中老年人中可能与短睡眠时间和/或长睡眠时间相关的特征。通过使用多项逻辑回归模型，对参与健康体检者研究的总共84,094名受试者（27,717名男性和56,377名女性）进行了分析。为了评估社会人口学因素、生活方式因素、心理状况、人体测量结果和健康状况是否与短睡眠时间和/或长睡眠时间相关，以6 - 7小时的睡眠时间作为参照组，估计了优势比（OR）和95%置信区间（CI），并考虑了假定的协变量。无论性别差异如何，我们发现不良行为和生活方式因素，包括低教育程度、失业、未婚、当前吸烟状况、缺乏运动、饮食不规律、心理社会幸福感差、频繁的压力事件以及自我健康评价差，都与异常睡眠时间显著相关。同样，糖尿病和抑郁症在男性和女性中均与异常睡眠时间呈正相关。我们的研究结果表明，社会人口学特征低、不良生活方式因素、心理状况差以及某些疾病发病率可能与韩国中老年人的异常睡眠时间有关。
