Depression often follows a recurrent or chronic course influenced by various factors. Social support is associated with depression both by quantity and quality, however, the concurrent change with depression is unclear. This study aimed to determine the trajectories of depressive symptoms and social support over 23 years as well as their interrelationship.
We analyzed data from 6787 participants of a Swedish population-based cohort study at four time points and across 23 years. Depressive symptoms were assessed using the Major Depression Inventory and social support was assessed with the Interview Schedule for Social Interaction. The trajectories of depressive symptoms and social support were determined using group-based dual trajectory modeling. Multinomial logistic regression analysis assessed the association between the trajectories of depressive symptoms and social support.
Six trajectories of depressive symptoms and three trajectories of social support were identified. The trajectories were highly associated. Individuals without depressive symptoms were likely to have a stable high availability of social support, and those with persistent depressive symptoms were likely to experience a stable low availability of social support.
Our findings imply that social support should be considered in the management of depressive symptoms.
抑郁症通常呈复发或慢性病程，受多种因素影响。社会支持在数量和质量上均与抑郁症相关，然而，其与抑郁症的同步变化尚不清楚。本研究旨在确定23年间抑郁症状和社会支持的轨迹及其相互关系。
我们分析了一项瑞典基于人群的队列研究中6787名参与者在四个时间点、跨越23年的数据。使用《重性抑郁量表》评估抑郁症状，用《社会交往访谈问卷》评估社会支持。采用基于组的双轨迹模型确定抑郁症状和社会支持的轨迹。多项逻辑回归分析评估抑郁症状轨迹与社会支持之间的关联。
确定了六条抑郁症状轨迹和三条社会支持轨迹。这些轨迹高度相关。无抑郁症状的个体可能拥有稳定的高社会支持可得性，而有持续性抑郁症状的个体可能经历稳定的低社会支持可得性。
我们的研究结果表明，在抑郁症状的管理中应考虑社会支持。
