The study by Peppard et al. examines the prevalence of sleep-disordered breathing (SDB) in the United States, focusing on the period from 1988-1994 and 2007-2010. Using data from the Wisconsin Sleep Cohort Study, an ongoing community-based study, the researchers estimated the prevalence of moderate to severe SDB (apnea-hypopnea index, AHI ≥15) among adults aged 30-70 years. The results show a significant increase in SDB prevalence over the two periods, with the current estimates being 10% for men and 9% for women in the 30-49 age group, and 17% for men and 3% for women in the 50-70 age group. These increases are attributed to the rising obesity rates in the US population. The study also highlights the health consequences of SDB, including hypertension, cardiovascular diseases, cognitive decline, and premature death. The findings underscore the need for updated prevalence estimates and the development of robust models to track SDB prevalence over time.The study by Peppard et al. examines the prevalence of sleep-disordered breathing (SDB) in the United States, focusing on the period from 1988-1994 and 2007-2010.
