The literature emphasizes depression and poor sleep quality as problems that affect many elderly individuals. However, these problems have been related in few studies and there is no meta-analysis performed so far on this relationship. The present research reviewed the studies performed on the subjective sleep quality in order to understand how it relates to depression in older adults. The review was conducted in January 2016 and comprised publications between 2005 and 2015. Based on the electronic databases Web of Science and EBSCO, we used the keywords 'sleep quality', 'depression', and 'older' to identify the empirical studies performed. After assessing the collected studies, we selected those that presented the elderly as participants, resulting in nine papers (N = 3069). A random-effects method was used to evaluate the relationship between depression and sleep. We found that an older person's lack of good sleep quality is significantly related with depression. The main limitation of this study was the difficulty in collecting a greater number of studies. Future research should consider the importance of additional variables (e.g. moderators) in order to understand and investigate viable interventions for prevention and health promotion in the elderly.
文献强调抑郁症和睡眠质量差是影响许多老年人的问题。然而，这些问题在少数研究中有所关联，到目前为止还没有针对这种关系进行的荟萃分析。本研究回顾了关于主观睡眠质量的研究，以了解其与老年人抑郁症的关系。该回顾于2016年1月进行，涵盖了2005年至2015年期间的出版物。基于科学网和EBSCO电子数据库，我们使用关键词“睡眠质量”“抑郁症”和“老年人”来识别所进行的实证研究。在评估所收集的研究后，我们选择了那些以老年人为参与者的研究，最终得到9篇论文（N = 3069）。我们使用随机效应方法来评估抑郁症与睡眠之间的关系。我们发现老年人睡眠质量不佳与抑郁症显著相关。本研究的主要局限性在于难以收集更多的研究。未来的研究应考虑其他变量（如调节变量）的重要性，以便了解和研究针对老年人预防和健康促进的可行干预措施。
