INTRODUCTIONAsthma is the most common chronic airway disorder and affects mainly children. 1 It is a complex disorder characterized by recurrent attacks of wheezing, coughing and shortness of breath. 1 Asthma is estimated to affect around 334 million people globally. 2 Education is an important aspect of child development, and asthma can impact a child's quality of life, which can lead to more absences, less participation in school activities and poor academic performance. A study conducted by Bener et al in Qatar found that over half of all asthmatic children had poor examination scores that significantly differed from their healthy peers (p<0.001; poor, 34.5% and average, 31.4%). 3 Similarly, in a population based sample of American children in grades 1 to 12 that compared asthmatic children to their healthy peers, asthmatic children were more likely to experience grade failure (18% vs 15%), learning disabilities (9% vs 5%) and more absences. Even after adjusting for demographic factors, children in fair-poor health were two times more likely to report learning disability compared with those in good-excellent health. 4 ABSTRACT Background: Studies about impact of asthma on school performance are limited in the published literature especially in Saudi Arabia. This study was done to assess the effect of asthma on school performance and examine the relationship between asthma control and school achievement. Methods: A cross-sectional study with a follow up of participants until the end of 2nd semester of (2015)(2016). It was conducted among governmental intermediate school students (males and females 13 to15 years old) in Riyadh city, Saudi Arabia. Riyadh city is divided into five main sectors; two schools were randomly selected from each sector. Students were recruited from all three grades (first, second and third year) with a total sample of 1058 students. A self-administered questionnaire was given to the students at the start of the 2 nd semester. The students' exam results were collected at the end of the 2 nd semester. Results: After adjusting for covariates, a significant difference in final average points was found between students with uncontrolled asthma (n=87) and controlled asthma (n=107) with an adjusted mean difference of 5.38 (95% CI 2.09-8.67 p<0.001). No significant difference in final average points was found between asthmatic (n=210) and nonasthmatic (n=848) students with an adjusted mean difference of 1.24 (95% CI-0.57-3.06) p=0.179. Significant associations were detected between gender, nationality, socioeconomic status and poor school performance p<0.01.
Conclusions:The study results suggest that students with uncontrolled asthma are more likely to perform worse in all subjects than students with controlled asthma.
