It was published <a href="https://bmcpublichealth.biomedcentral.com/articles/10.1186/s12889-024-19113-5">online</a> in <em>BMC Public Health</em>.</p> <h2>LIMITATIONS:</h2> <p>The majority of the studies included were cross-sectional, which cannot establish causality. High heterogeneity was found among the included studies, possibly due to differences in research design, population characteristics, and exposure levels. Some studies did not adjust for important confounding factors such as outdoor activities.</p> <h2>DISCLOSURES:</h2> <p>The study was supported by grants from the Educational Commission of Anhui Province of China, Research Fund of Anhui Institute of Translational Medicine, and National Natural Science Foundation of China. The authors declared no conflicts of interest.<span class="end"/></p> <p> <em>This article was created using several editorial tools, including AI, as part of the process.
