The risk of death increases with the severity of a person’s sleep apnoea, according to a new study.
The research, published in the Journal of Clinical Sleep Medicine,is the first to find that sleep apnoea severity is linked with death risk.
Researchers analysed data from 2,240 Asian people aged 40 and older with sleep apnoea or snoring. They were put into groups based on sleep apnoea severity (no sleep apnoea, moderate sleep apnoea, and severe sleep apnoea).
Over the course of the study researchers found that 1% of people with no sleep apnoea died over the study period, compared with 2% of people with mild sleep apnoea, 3.54% of people with moderate sleep apnoea and 4.2% of people with severe sleep apnoea. Heart disease and stroke were the cause of about a third of the deaths.
Overall, the risk of dying was 2.47 times higher among people with severe sleep apnoea compared with people without sleep apnoea.
