The association between PM2.5 level and respiratory tract infections among children: A cross-sectional study

Background: exposure and respiratory tract infections (RTIs) in school-aged children and further exploring this association within male and female subgroups, an aspect that has received limited attention in this setting. Objective: exposure and RTIs in school-aged children, and to explore this association within male and female subgroups. Methods: exposure and RTIs. Results: exposure (adjusted OR = 7.883, 95% CI: 3.228-19.250, p < 0.001). Conclusions: exposure on children's respiratory health and to inform appropriate mitigation strategies.
