The prevalence of OSAS

The prevalence of obstructive sleep apnea.

In today’s post we reflect the results of a study on the prevalence of obstructive sleep apnea syndrome (OSAS) conducted by the University of Wisconsin, EEUU. In this study, 1,520 participants (96% of them non-hispanic whites) were enrolled, and a total of 4,563 sleep studies were performed for the diagnosis of sleep-disordered breathing (SDB) between 1988 and 2011, pictured in the following table:

Increased Prevalence of Sleep-Disordered Breathing in Adults

Table 1: Participants. Increased Prevalence of Sleep-Disordered Breathing in Adults.

The table shows that 32.7 % of the population presented suffered from mild, moderate or severe OSAS (AHI> 5).

62 % of the studies were performed in adults between 50 and 70 years of age. Women constituted up to 45 % of the participation. One third of the study revealed mild, moderate or severe ORS (AHI> 5).

The graphic shows how 45 % of men between 50-70 years old suffered from SRT (AHI> 5) and that the prevalence increased significantly with body mass index.

Table 2: Mild to Severe Sleep Apnea.

Table 2: Mild to Severe Sleep Apnea.

Table 2 shows that 18.3 % of men between 30-49 years and 36.6 % of men between 50 and 70 years of age are overweight and have mild to severe sleep apnea.
