Is long-term exposure to air pollution associated with poor sleep quality in rural China?

ABSTRACT:

Background

Poor sleep quality is associated with poor quality of life and may even lead to mental illnesses. Several studies have indicated the association between exposure to air pollution and sleep quality. However, the evidence is very limited in China, especially in rural areas.

Methods

Participants in this study were obtained from the Henan Rural Cohort established during 2015-2017. Sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI) in the baseline survey. Poor sleep quality was defined by the global score of PSQI > 5. Participants' exposures to PM_2.5, PM₁₀ (particulate matter with aerodynamic diameters ≤2.5 μm and 10 μm, respectively) and NO₂ (nitrogen dioxide) during the three years before the baseline survey w
