Little is known about temporal trajectories of social support in adults with type 2 diabetes (T2D) and how they are associated with diabetes-related outcomes. This study identified and explored different trajectories of social support in a community sample of adults with T2D, as well as the extent to which different trajectories were prospectively associated with depressive symptoms and functional disability.
Data came from five annual waves of the Evaluation of Diabetes Treatment study (N = 1077). Social support, depressive symptoms, and functional disability were assessed via self-report. Separate analyses were conducted to examine the associations between social support trajectories, depressive symptoms, and functional disability, adjusting for demographic characteristics, diabetes-related covariates, and baseline depressive symptoms and functional disability.
Latent class growth modeling identified four distinct social support trajectories. Trajectory Groups 1 and 2 comprised participants with persistently low and persistently moderate-low social support, respectively. Trajectory Groups 3 and 4 included participants with persistently moderate-high and persistently high social support, respectively. People with persistently low social support reported higher functional disability relative to those with persistently moderate-high and persistently high social support.
The findings of the present study indicate that temporal patterns of social support are a predictor of future functional disability among adults with T2D.
关于 2 型糖尿病（T2D）成年人中社会支持的时间轨迹知之甚少，以及它们与糖尿病相关结局的关系如何。本研究在 T2D 成人的社区样本中确定和探讨了社会支持的不同轨迹，以及不同轨迹与抑郁症状和功能障碍的前瞻性关联程度。
数据来自 Evaluation of Diabetes Treatment 研究的五个年度波次（N=1077）。社会支持、抑郁症状和功能障碍通过自我报告进行评估。分别进行分析，以检查社会支持轨迹、抑郁症状和功能障碍之间的关联，调整人口统计学特征、糖尿病相关协变量以及基线抑郁症状和功能障碍。
潜在类别增长模型确定了四种不同的社会支持轨迹。轨迹组 1 和 2 分别包括持续低和持续中低社会支持的参与者。轨迹组 3 和 4 包括持续中高和持续高社会支持的参与者。与持续中高和持续高社会支持相比，持续低社会支持的人报告了更高的功能障碍。
本研究的结果表明，社会支持的时间模式是预测 T2D 成年人未来功能障碍的一个因素。
