Asthma Control Among Adults in Saudi Arabia: A Systematic Review and Meta-Analysis

Background/Objectives: Asthma is a condition caused by chronic lower airway inflammation. Its primary treatment focuses on managing the condition and reducing the frequency of exacerbation episodes. Monitoring the level of asthma control among adults is essential for both clinical care and public health planning. This systematic review aimed to assess the level of asthma control among adults in Saudi Arabia and to determine the prevalence of controlled asthma in this population. Methods: The literature search was conducted using PubMed. We included all English-language, empirical, quantitative studies that investigated the prevalence of asthma control among Saudi adults. National Institutes of Health (NIH) Study Quality Assessment Tools guided determination of the quality of the included studies. This review is registered with PROSPERO (CRD42024484711). Results: Of the 107 initially identified studies, 17 met the inclusion criteria. Quality assessment tool rated 11 studies as good, 5 as fair, and 1 as poor. Most of the included studies used cross-sectional design from different geographical locations and varied in sample size. Overall, the prevalence of uncontrolled asthma among Saudi adults ranged from 23.4% to 68.1%. In some studies, well-controlled asthma was reported in as few as 3% of patients. Factors associated with uncontrolled asthma included lower educational attainment, unemployment, low income, female gender, tobacco use, poor medication adherence, and lack of regular medical follow-up. Environmental triggers and comorbid conditions, such as allergic rhinitis, were also frequently cited as contributing factors. Conclusions: Asthma control among adults in Saudi Arabia remains a significant public health concern. Improving outcomes requires a multifaceted approach that includes patient education, regular follow-up care (including pulmonary function tests, asthma severity assessments, and personalized treatment plans), and broader public health initiatives aimed at reducing exposure to allergens and pollutants. Strengthening primary care services and implementing nationwide asthma management programs may play a critical role in enhancing disease control and improving quality of life. Continued research in this field is strongly recommended.
