In black men in a certain age group, obstructive sleep apnea occurs in a more severe form than in white men, according to a recent study. Between black women and white women with sleep apnea, this difference does not exist.
The study published in the Journal of Clinical Sleep Medicine examined 512 patients with obstructive sleep apnea syndrome (OSAS) for 2.5 years. The group of patients studied consisted of 340 black and 172 white patients. It was found that in dark men under 40 years and men between 50 and 59 years, sleep apnea occurred in a more severe form than in white men in the same age group. The reason for this difference is unclear. Perhaps anatomical differences or the way in which the brain drives respiration plays a role.
Obstructive sleep apnea syndrome is a medical description for breathing problems during sleep, where breathing is difficult or even temporarily stops. This syndrome is often abbreviated as OSAS. Typical features to recognize the obstructive sleep apnea syndrome are snoring, difficulty breathing and stopping breathing during sleep. This is often accompanied by severe perspiration and restless sleep. During the day there may be fatigue and reduced performance because the sleep pattern is disturbed.
