    摘要

    Background: Although the adverse health effects of ambient air pollution are well documented, evidence on the depression effects of household air pollution (HAP) are scarce. Objectives: We investigated the effects of HAP exposure from the use of solid fuel on depression using a nationally representative dataset of middle-aged and older population in China. Methods: By employing the propensity score matching method, we first matched the type of household fuel based on background information, including demographic characteristics, lifestyles, health status, and household economic levels. Based on the matched data, we conducted OLS and logistic regressions with cluster standard error at community level to examine the effects of household solid fuel use on depression and adjusted for potential confounders. Heterogeneous effects for vulnerable population were also considered. Results: We found a significantly higher Center for Epidemiologic Studies Depression Scale (CES-D) score and depression risk among current household solid fuel users. After matching and adjusting for potential confounders, current solid fuel users had a higher CES-D score of 0.59 (95% confidence interval [CI]: 0.31, 0.89) than clean fuel users. The OR of depression risk were 1.26 (95% CI: 1.14, 1.41). Solid fuel users had the highest CES-D scores (β = 0.99, 95% CI: 0.62, 1.36) and depression risk (OR = 1.49, 95% CI: 1.30, 1.73) for over five years. These associations were generally higher in females, participants aged 65 years and older, with a BMI ≥ 25, with low education, with low household economic levels, and those suffer from chronic diseases, including diabetes, chronic lung diseases, and cardiovascular diseases. Conclusions: Exposure to HAP from solid fuel combustion was linked with strong depression outcomes. Findings suggested a need to strengthen public health efforts, such as controlling the social, health, and economic costs of depression by taking the physical environment, including HAP exposure, into account.
