Prevalence, associated factors, and control level of asthma symptoms among adolescents in Northern Jordan

Abstract

To investigate the prevalence, associated factors, and control level of asthma in Jordanian high school students. A descriptive, comparative, cross sectional design was used and a cluster sample of 2691 students (mean age = 14.5 years, 51.0% girls), drawn from eight randomly selected public high schools in Northern Jordan, participated in the study. Each student had the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire completed in the classroom between February and May, 2015. The prevalence of recent wheezing in the last 12 months was 11.7% whereas the prevalence of diagnosed asthma was 6.2%. About 49% of students experienced cough all the time, and 33.5% experienced waking up at night due to wheezing some of the time. About 30.9% of students reported moderate to big exercise-induced asthma. The mean total Asthma Control Test (ACT) score was 5.85 (SD = 3.56) with all of students reporting uncontrolled asthma during the last month. Higher rates of asthma symptoms were reported by females, 10th graders, and students with negative family history. Importantly, students with diagnosed asthma or recent wheezing reported higher rates of ever smoking tobacco vs. non-asthmatics (p < 0.000); dual (18.6% vs. 9.8%), cigarettes only (11.2% vs. 7.3%), and waterpipe only (18.0% vs. 14.7%). Overall, students with asthma or wheezing had increased rates of tobacco smoking. Policies need to be set and enforced to provide a better environment for these youth, especially making all schools smoke-free zones. A multifaceted, comprehensive awareness and management program is required in schools to control and manage asthma symptoms.
