Previous studies have indicated depression was associated with environmental exposures, but evidence is limited for the association between outdoor light at night (LAN) and depression. This study aims to examine the association between long-term outdoor LAN exposure and depressive symptoms using data from the Chinese Veteran Clinical Research platform. A total of 6445 male veterans were selected from 277 veteran communities in 18 cities of China during 2009‒2011. Depressive symptoms were evaluated using the Chinese version of the Center for Epidemiological Studies Depression scale. Outdoor LAN was estimated using the Global Radiance Calibrated Nighttime Lights data. The odds ratio and 95% confidence intervals of depressive symptoms at the high level of outdoor LAN exposure against the low level during the 1 years before the investigation was 1.49 (1.15, 1.92) with p-value for trend < 0.01, and those associated with per interquartile range increase in LAN exposure was 1.22 (1.06, 1.40).
先前的研究表明，抑郁与环境暴露有关，但有关夜间室外光 (LAN) 与抑郁之间关系的证据有限。本研究旨在利用中国退伍军人临床研究平台的数据，检验长期户外 LAN 暴露与抑郁症状之间的关联。2009 年至 2011 年期间，从中国 18 个城市的 277 个退伍军人社区中选取了 6445 名男性退伍军人。使用中文版流行病学研究抑郁量表评估抑郁症状。使用全球辐射校准夜间灯光数据估算户外 LAN。在调查前 1 年内，高水平户外 LAN 暴露与低水平户外 LAN 暴露相比，抑郁症状的比值比和 95%置信区间为 1.49（1.15，1.92），趋势检验的 p 值 < 0.01，与 LAN 暴露每增加一个四分位间距相关的比值比为 1.22（1.06，1.40）。
