A systematic review of 11 studies found that the pooled prevalence of obstructive sleep apnea (OSA) among young adults (18–30 years) is 16% (95% CI 8–29%, I²=92%, τ²=1.47). The prevalence varied by region, with 23% in Asia and Australia, 9% in Europe, and 13% in North and South America. However, data from Africa were unavailable. The study highlights the need for OSA screening and intervention in young adults, as early detection can prevent complications related to comorbidities. Factors influencing prevalence included hypopnea definition, AHI threshold, and device type. Most studies included healthy volunteers, suggesting the disease burden may be underestimated. The review also notes that OSA is more prevalent in males than females, and that diagnostic criteria varied between studies, affecting prevalence estimates. The study emphasizes the importance of standardized diagnostic methods and the need for further research in underrepresented regions. The findings underscore the significance of OSA in young adults and the necessity for improved screening and treatment strategies.A systematic review of 11 studies found that the pooled prevalence of obstructive sleep apnea (OSA) among young adults (18–30 years) is 16% (95% CI 8–29%, I²=92%, τ²=1.47).
