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. Similarly, each abnormally shallow breathing event is called a hypopnea.
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.OSA may increase risk for driving accidents and work-related accidents. If OSA is not treated, one has an increased risk of other health problems such as diabetes.
Of 168 RA patients,SA high risk was observed in 71 patients (42%) and daytime sleepiness in 50 patients (29.7%). Patients with high SA risk showed higher BMI (29 ± 5 vs 26 ± 5, p <0.001), higher disease activity [DAS28 (4.5 ± 1.4 vs 3.7 ± 1.2, p <0.001) and RAPID3 (14 ± 7 vs 10 ± 6, p <0.002)], and worse functional capacity [HAQ (1.3 ± 0.7 vs 0.9 ± 0.7, p <0.01)].
