Abstract

Background: Climate factors such as solar radiation could contribute to mood disorders, but evidence of associations between exposure to solar radiation and mood disorders is mixed and varies by region.

Objective: To evaluate the association of solar radiation with depression and distress among residents living in U.S. Gulf states.

Methods: We enrolled home-visit participants in the Gulf Long-Term Follow-up Study who completed validated screening questionnaires for depression (Patient Health Questionnaire-9, N = 10,217) and distress (Kessler Psychological Distress Questionnaire, N = 8,765) for the previous 2 weeks. Solar radiation estimates from the Daymet database (1-km grid) were linked to residential addresses. Average solar radiation exposures in the seven (SRAD7), 14 (SRAD14), and 30 days (SRAD30) before the home visit were calculated and categorized into quartiles (Q1-Q4). We used generalized linear mixed models to estimate prevalence ratios (PR) and 95% confidence intervals (CI) for associations between solar radiation and depression/distress.

Results: Higher levels of SRAD7 were non-monotonically inversely associated with depression [PR_Vs.Q1 (95%CI): Q2 = 0.81 (0.68, 0.97), Q3 = 0.80 (0.65, 0.99), Q4 = 0.88 (0.69, 1.15)] and distress [PR_Vs.Q1 (95%CI): Q2 = 0.76 (0.58, 0.99), Q3 = 0.77 (0.57, 1.06), Q4 = 0.84 (0.58, 1.22)]. Elevated SRAD14 and SRAD30 appeared to be associated with decreasing PRs of distress. For example, for SRAD14, PRs were 0.86 (0.63-1.19), 0.80 (0.55-1.18), and 0.75 (0.48-1.17) for Q2-4 versus Q1. Associations with SRAD7 varied somewhat, though not significantly, by season with increasing PRs of distress in spring and summer and decreasing PRs of depression and distress in fall.

Impact statement: Previous research suffered from exposure misclassification, which impacts the validity of their conclusions. By leveraging high-resolution datasets and Gulf Long-term Follow-up Cohort, our findings support an association between increased solar radiation and fewer symptoms of mood disorders.

太阳辐射与墨西哥湾沿岸居民情绪失调之间的关系。

背景：太阳辐射等气候因素可能会导致情绪失调，但太阳辐射照射与情绪失调之间的关系证据不一，且因地区而异：目的：评估太阳辐射与美国海湾各州居民抑郁和痛苦之间的关系：我们招募了海湾地区长期随访研究（Gulf Long-Term Follow-up Study）的家访参与者，他们在过去两周内完成了有效的抑郁筛查问卷（患者健康问卷-9，N = 10,217 ）和困扰问卷（凯斯勒心理困扰问卷，N = 8,765 ）。来自 Daymet 数据库（1 公里网格）的太阳辐射估计值与住宅地址相关联。我们计算了家访前 7 天（SRAD7）、14 天（SRAD14）和 30 天（SRAD30）的平均太阳辐射量，并将其分为四等分（Q1-Q4）。我们使用广义线性混合模型估算太阳辐射与抑郁/压力之间的患病率比（PR）和 95% 置信区间（CI）：结果：较高水平的 SRAD7 与抑郁呈非单调反比关系[PRVs.Q1 (95%CI)：Q2 = 0.81 (0.68, 0.97), Q3 = 0.80 (0.65, 0.99), Q4 = 0.88 (0.69, 1.15)]和痛苦[PRVs.Q1 (95%CI)：Q2=0.76（0.58，0.99），Q3=0.77（0.57，1.06），Q4=0.84（0.58，1.22）]。SRAD14 和 SRAD30 的升高似乎与痛苦 PR 的降低有关。例如，就 SRAD14 而言，Q2-4 与 Q1 的 PR 分别为 0.86（0.63-1.19）、0.80（0.55-1.18）和 0.75（0.48-1.17）。与 SRAD7 的关系因季节不同而有一定差异，但差异不大，春季和夏季的痛苦 PR 增加，秋季的抑郁和痛苦 PR 减少：以往的研究存在暴露分类错误，这影响了研究结论的有效性。通过利用高分辨率数据集和海湾长期跟踪队列，我们的研究结果支持太阳辐射增加与情绪障碍症状减少之间存在关联。

期刊介绍： Journal of Exposure Science and Environmental Epidemiology (JESEE) aims to be the premier and authoritative source of information on advances in exposure science for professionals in a wide range of environmental and public health disciplines. JESEE publishes original peer-reviewed research presenting significant advances in exposure science and exposure analysis, including development and application of the latest technologies for measuring exposures, and innovative computational approaches for translating novel data streams to characterize and predict exposures. The types of papers published in the research section of JESEE are original research articles, translation studies, and correspondence. Reported results should further understanding of the relationship between environmental exposure and human health, describe evaluated novel exposure science tools, or demonstrate potential of exposure science to enable decisions and actions that promote and protect human health.
