Sleep apnea is a sleep disorder characterized by pauses in breathing or instances of shallow or infrequent breathing during sleep. Each pause in breathing, called an apnea, can last for several seconds to several minutes, and may occur, by definition, at least 5 times in an hour.
People have issues with excessive daytime sleepiness (EDS) and impaired alertness. In other words, common effects of sleep apnea include daytime fatigue, a slower reaction time, and vision problems.SA may increase risk for driving accidents and work-related accidents. If SA is not treated, one has an increased risk of other health problems such as diabetes.
During the study period, 586 patients of the 2290 sleep studies fulfilled the inclusion criteria. Subjects who participated in study protocols (N = 1228) or in continuous positive airway pressure titration studies (N = 100), women (N = 303), other ethnicities (N = 70) and Japanese descendants mixed with other races (N = 5) were excluded. Among the 586 patients included, 61 were Japanese descendants.
