Abstract

Objectives

Indoor air pollution exposure is harmful to people's physical and mental health, especially in the elderly population. Depressive symptoms are the most common mental health issue among elderly individuals. However, evidence linking the frequency of indoor natural ventilation to depressive symptoms in the elderly population is limited.

Methods

This study included 7887 individuals 65 years and older from 2017 to 2018 the China Longitudinal Healthy Longevity Survey (CLHLS). The frequency of indoor window ventilation was measured as the self-reported times of ventilation of indoor window per week in each season, and the four seasons' scores were added up to calculate the annual ventilation frequency. Depressive symptoms were measured by the 10-item Center for Epidemiologic Studies Short Depression Scale (CESD). Using three models adjusted for demographic, socio-economic, health status, and environmental factors successively, the correlation between indoor window ventilation frequency and depressive symptoms was verified through logistic regression.

Results

Among the 7887 elderly people included in this study, 1952 (24.7 %) had depressive symptoms. In the fully adjusted model, compared with the lower indoor annual ventilation frequency group, high indoor annual ventilation frequency group was significantly associated with a 33 % (OR: 0.67, 95%CI: 0.51–0.88) lower probability of depressive symptoms. Subgroup analysis and sensitivity analysis yielded similar results.

Conclusions

High frequency of window ventilation is significantly associated with the lower risk of depressive symptoms in Chinese individuals aged 65 and older. This result provides strong evidence for health intervention and policy formulation.

中国老年人开窗通风频率与抑郁症状之间的关系。

目的：室内空气污染对人们的身心健康有害，对老年人群尤其如此。抑郁症状是老年人最常见的心理健康问题。然而，将室内自然通风频率与老年人抑郁症状联系起来的证据却很有限：本研究纳入了 2017 年至 2018 年中国健康长寿纵向调查（CLHLS）中 7887 名 65 岁及以上的老年人。室内开窗通风频率以每个季节每周自报的室内开窗通风次数为测量指标，四季得分相加计算全年通风频率。抑郁症状采用 10 项流行病学研究中心抑郁简表（CESD）进行测量。先后使用人口、社会经济、健康状况和环境因素调整后的三个模型，通过逻辑回归验证了室内开窗通风频率与抑郁症状之间的相关性：在 7887 名老年人中，1952 人（24.7%）有抑郁症状。在完全调整模型中，与室内年通风频率较低的组别相比，室内年通风频率较高的组别出现抑郁症状的概率显著降低了 33% （OR：0.67，95%CI：0.51-0.88）。分组分析和敏感性分析也得出了相似的结果：结论：在 65 岁及以上的中国人中，开窗通风频率高与抑郁症状发生风险低有明显关系。这一结果为健康干预和政策制定提供了有力的证据。
