Environmental Exposure and Pediatric Asthma Prevalence in Saudi Arabia: A Cross-Sectional Study

Asthma is a chronic respiratory disease characterized by recurrent episodes of wheezing and shortness of breath. Currently, there is no cure for asthma. However, through accurate diagnosis, appropriate therapy, and effective management strategies, individuals with asthma can achieve a better quality of life. This study focused on determining the prevalence and environmental risk factors of pediatric asthma among children in Saudi Arabia.

This cross-sectional study was undertaken from January 2023 to August 2023, encompassing five key regions in Saudi Arabia: Central, Eastern, Northern, Southern, and Western. A structured online questionnaire was disseminated to parents/guardians of children aged 2-18 with a confirmed diagnosis of asthma. The objective was to garner insights regarding pediatric asthma prevalence and associated risk factors within these regions. The questionnaire was designed with considerations for sociodemographic factors, environmental exposures, and known asthma triggers. From the survey's distribution, a total of 1666 responses were accumulated and processed for further analysis.

The survey saw the participation of 1666 respondents. The age bracket of 8-13 years had the highest representation, accounting for 52.5% of the total participants. From the total cohort, 26.9% had been diagnosed with pediatric asthma. It was also observed that 56.7% of the participants resided in areas marked by high traffic or were proximate to busy roads. Additionally, 30.7% of the respondents pinpointed specific times in the year when asthma symptoms intensified. When dissecting the data, it was discerned that there were statistically significant associations between the prevalence of pediatric asthma, gender, and the regions of Saudi Arabia with reference to air pollution exposure. Notably, gender had an odds ratio of 1.12, while the regional distribution held an odds ratio of 1.

Our study vividly highlights the intricate landscape of pediatric asthma across Saudi Arabia, indicating its prevalence and drawing attention to associated risk factors. Noteworthy observations include the pronounced impact of gender and regional variances, particularly concerning air pollution exposure, on asthma incidence. The insights gleaned from this research are invaluable in steering the formulation and implementation of strategic interventions geared towards bolstering children's health and enhancing their life quality in regions bearing the brunt of pediatric asthma.
