 The prevalence of sleep apnea is increasing globally, but population-based studies have reported varying rates of prevalence estimates, and data on the incidence of clinically diagnosed sleep apnea are sparse. Population-based studies have also shown that multimorbidity is common among people who develop sleep apnea, and the pathways to multimorbidity have not been thoroughly investigated. To better understand the current epidemiology of sleep apnea in Finland, the overall burden of comorbidities, and the multimorbidity profiles of individuals with incidence sleep apnea, researchers conducted a retrospective study using data from January 2016 through December 2019. They found that the prevalence of clinical sleep apnea was 3.7%, and that one year after diagnosis, it had increased to 6.5%. Additionally, they discovered that 63% of individuals with incidence sleep apnea were highly multimorbid, meaning they presented with four or more comorbidities. Among these individuals, hypertension and metabolic diseases such as obesity and diabetes, cardiovascular diseases, muscle.
