Abstract

Background

Outdoor artificial light at night (ALAN) has emerged as a significant source of environmental pollution, however its association with antenatal depression and anxiety symptoms has been rarely explored before.

Methods

This study was based on a cohort study conducted at the Maternal and Child Health Care Center in Ma'anshan City, Anhui Province, China, which ultimately included 1047 pregnant women. Depression and anxiety symptoms were evaluated utilizing the self-administered Patient Health Questionnaire (PHQ-9) and the 7-item Generalized Anxiety Scale (GAD-7), respectively. Exposure levels to outdoor ALAN were calculated utilizing satellite data and the participants' usual addresses. Logistic regression and restricted cubic spline were used to assess the association between exposure to outdoor ALAN and depression and anxiety symptoms in pregnant women.

Results

After adjusting for confounding factors, high ALAN exposure during the pre-pregnancy period (OR_depression = 3.16, 95% CI: 1.14–8.75; OR_anxiety = 3.09, 95% CI: 1.51–6.28) and first trimester (OR_depression = 2.90, 95% CI: 1.13–7.45; OR_anxiety = 3.11, 95% CI: 1.55–6.25) were associated with increased risks of antenatal depression and anxiety symptoms. Restricted cubic spline analyses showed the above associations were not nonlinear.

Conclusion

Our study is the first to propose that exposure to high levels of outdoor ALAN three months before pregnancy and during the first trimester of pregnancy is a risk factor for antenatal depression and anxiety symptoms.

夜间接触室外人造光与产前抑郁和焦虑症状之间的关系：中国的一项回顾性队列研究

背景：室外夜间人造光（ALAN）已成为环境污染的重要来源，但其与产前抑郁和焦虑症状的关系尚未被探索。方法：本研究基于在中国安徽省马鞍山市妇幼保健中心进行的一项队列研究，最终包括1047名孕妇。抑郁和焦虑症状分别采用自填患者健康问卷（PHQ-9）和7项广泛性焦虑量表（GAD-7）进行评估。利用卫星数据和参与者的通常地址计算室外ALAN暴露水平。采用Logistic回归和限制三次样条法评估孕妇暴露于室外ALAN与抑郁和焦虑症状之间的关系。结果：在调整混杂因素后，妊娠前期高ALAN暴露(or抑郁= 3.16,95% CI: 1.14 ~ 8.75；or焦虑= 3.09,95% CI: 1.51 ~ 6.28)和妊娠早期(or抑郁= 2.90,95% CI: 1.13 ~ 7.45；或焦虑= 3.11,95% CI: 1.55 ~ 6.25)与产前抑郁和焦虑症状的风险增加相关。限制三次样条分析表明上述关联不是非线性的。结论：我们的研究首次提出，在怀孕前三个月和怀孕前三个月暴露于高水平的户外ALAN是产前抑郁和焦虑症状的一个危险因素。
