Abstract

Objective: To evaluate the direct, indirect, and total prospective effects of serum concentrations of 25-hydroxycholecalciferol (25[OH]D) on depressive symptoms in older adults.

Methods: Data from the second (2013-2015) and third (2017-2019) waves of the EpiFloripa Aging Cohort Study (= 60 years) were analyzed. Depressive symptoms were assessed with the 15-item Geriatric Depression Scale. 25(OH)D levels were measured using the microparticle chemiluminescence method. A directed acyclic graph was constructed to identify the minimum set of adjustments. Structural equation modeling analysis was used to determine the effects of 25(OH)D on depressive symptoms.

Results: Data from 574 older adults (63.1% female) were analyzed. In the follow-up (n=390), 16.2% of them presented severe depressive symptoms (= 6 points). Structural equation modeling analysis revealed that 25(OH)D had a small direct negative effect (ß = -0.11, p < 0.05) and an overall negative effect (ß = -0.13; p < 0.05) on depressive symptoms in wave 3 (increased 25[OH]D led to decreased depressive symptoms). No direct or indirect effect on depressive symptoms was found in wave 2.

Conclusion: Our findings indicate a prospective association between 25(OH)D and depressive symptoms, suggesting a long-term effect in older adults from southern Brazil.

EpiFloripa 老龄队列研究中维生素 D 血清浓度与抑郁症状的前瞻性关联：结构方程建模方法。

目的评估血清中[25（OH）D，25-羟基钙化醇]浓度对老年人抑郁症状的直接、间接和总体前瞻性影响：分析了EpiFloripa老年队列研究第二波（2013-2015年）和第三波（2017-2019年）的数据（≥60岁）。抑郁症状通过 15 项老年抑郁量表（GDS-15）进行评估。25（OH）D水平采用微粒子化学发光法测定。通过构建有向无环图（DAG）来确定最小调整集。结构方程建模（SEM）分析用于确定 25（OH）D 对抑郁症状的影响：共分析了 574 名老年人（63.1% 为女性）的数据。在随访中（人数=390），16.2%的老年人出现了严重抑郁症状（>或=6分）。SEM 分析显示，25（OH）D 对第 3 波的抑郁症状有微小的直接负效应（β=-0.11，P < 0.05），对第 3 波的抑郁症状有总体负效应（β=-0.13；P < 0.05）（25（OH）D 的增加导致抑郁症状的减少）。结论：研究结果表明，25（OH）D与抑郁症状之间存在前瞻性联系：研究结果表明，25（OH）D 与抑郁症状之间存在前瞻性联系，表明这对巴西南部的老年人具有长期影响。
