Despite a growing body of evidence for the association between housing cost burden and psychological health, few studies have focused on the potential mediators of this association and the extent to which housing cost burden poses a threat to older adults' psychological health. This study aims to assess (a) the link between housing cost burden and psychological health among older adults and (b) how the association is mediated by material hardship.
Using thirteen waves of a nationally representative longitudinal study in Korea, this study assessed the association between housing cost burden and depressive symptoms among older adults aged 65 or over. Mediation tests were conducted to identify whether material hardship explains the link between housing cost burden and depressive symptoms. We used fixed-effects models to take into account individual-level heterogeneity.
Housing cost burden was significantly associated with depressive symptoms among older adults, regardless of their housing tenure status. Different types of material hardship partially mediated the association between housing cost burden and depressive symptoms in older adults. Older adults with severe housing cost burden are more susceptible to all types of material hardship compared to those with a moderate burden.
To contribute further to the social causation discussions, future studies should seek to identify protective factors of depressive symptoms among older adults and other potential mechanisms of the association between older adults' socioeconomic conditions and their psychological health.
尽管越来越多的证据表明住房成本负担与心理健康之间存在关联,但很少有研究关注这种关联的潜在中介因素,以及住房成本负担对老年人心理健康构成的威胁程度。本研究旨在评估:(a)住房成本负担与老年人心理健康之间的联系;(b)物质困难在这种关联中起到的中介作用。
本研究使用韩国一项具有全国代表性的纵向研究的 13 个波次的数据,评估了 65 岁及以上老年人的住房成本负担与抑郁症状之间的关联。采用中介检验来确定物质困难是否解释了住房成本负担与抑郁症状之间的联系。我们使用固定效应模型来考虑个体层面的异质性。
无论老年人的住房自有率如何,住房成本负担都与老年人的抑郁症状显著相关。不同类型的物质困难部分解释了老年人住房成本负担与抑郁症状之间的关联。与住房成本负担中度的老年人相比,负担严重的老年人更容易受到所有类型的物质困难的影响。
为了进一步推动社会因果关系的讨论,未来的研究应该努力确定老年人抑郁症状的保护因素,以及老年人社会经济状况与其心理健康之间关联的其他潜在机制。
