摘要

Background

Typically affecting people’s quality of life, dyssomnia is among the most prevalent chronic illnesses worldwide. A positive correlation between air pollution and dyssomnia has been demonstrated by epidemiological research. However, no meta-analyses evaluating the relationship between the prevalence of dyssomnia in people of all ages and air pollutants (PM2.5, PM10, NO2, SO2, and O3) were found.

Objectives

Conduct a meta-analysis utilizing data from current studies (until 2024) to provide reliable insights into the relationship between air pollution exposure and the likelihood of dyssomnia prevalence.

Methods

We systematically searched three databases for studies on air pollution and dyssomnia up to January 15, 2024. Random-effects models were used to estimate the pooled odds ratios (ORs) and 95% confidence intervals (95% CIs). Subgroup analyses, funnel plots, and meta-regression analyses were also performed.

Results

There were 11 studies from 4 different nations that involved 3,328,183 participants in total. The odds ratios (ORs) for PM2.5 and PM10 were 1.29 (1.16–1.44) and 1.13 (1.03–1.23) per 10 µg/m3 increase in pollutants, respectively. The OR per 10 µg/m3 increment of gaseous pollutants were 1.06 (1.00–1.12) for NO2 and 1.16 (1.04–1.31) for O3. No significant association was observed between SO2 and dyssomnia. Adults are more sensitive to air pollution than children or adolescents for that the effects of PM2.5、PM10 and SO2 were significantly stronger in adults than children or adolescents. The effect of air pollution on dyssomnia was more significant in developed countries than in developing countries. There was a difference in the subgroup test for PM10 between developed and developing countries.

Conclusion

This meta-analysis implies the relationship between the air pollution and dyssomnia. Economic status and age may influence the effect. It was suggested to provide guidance for disease prevention and explored potential avenues for further research.
