Prevalence and risk factors of asthma symptoms in Saudi university students in Najran, southern border region of Saudi Arabia

Background: Asthma prevalence in adults is globally increasing with variations between and within countries. Data are lacking regarding the prevalence of asthma among adults in Najran area , the southern region of Saudi Arabia. 
 
Objectives: The study aimed at estimating the prevalence and risk factors for asthma symptoms in Najran University students. 
 
Materials and Methods: A cross-sectional study was performed in Najran University Saudi students during the academic year 20172018. A modified translated International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire was distributed to Najran University Saudi students, males and females aged 18 and above living in Najran for more than 1 year. Samples were taken using multistage random sampling. 
 
Results: A total of 418 participants (269 males and 149 females) with a mean age of 21.05 ± 1.56 were included in the study. The prevalence of asthma depending on the wheezing symptom in the past 12 months was 27% and physician-diagnosed asthma was 13.6%. Most of the asthmatic subjects (>85%) have intermittent symptoms. The first-degree family history, active tobacco smoking, allergic rhinitis (AR), dust, and smoke are the major risk factors for asthma symptoms. 
 
Conclusions: The study revealed a high prevalence of self-reported asthma symptoms among adults in Najran University associated with a high prevalence of AR, which needs particular attention by the health stakeholders.
