Combination of Common Sleep Disorders Could Be Fatal: Study
According to researchers from Flinders University.
Researchers studied a large US-based data set of more than 5,000 people to understand the risks of co-morbid insomnia and obstructive sleep apnea (COMISA). The participants, aged around 60 at the start of the study and 52% female, were followed for around 15 years, with 1,210 people having died during this period.
The researchers found that participants with COMISA were twice as likely to have high blood pressure and 70% more likely to have cardiovascular disease as participants without insomnia or sleep apnea.
The study also showed that participants with COMISA had a 47% increased risk of death (for whatever reason) compared to participants without insomnia or sleep apnea, even when other factors known to increase blood pressure. mortality were taken into account.
“Insomnia and obstructive sleep apnea are the two most common sleep disorders, affecting 10-30% of the population, but people can often suffer from both at the same time,” said Dr Bastien Lechat of Flinders Health and Medical Research Institute: Sleep Health.
“Previously, little was known about the impact of COMISA, but what we did know is that for people with both conditions, the health outcomes are consistently worse than those without either. those who only suffer from it. “
“This is the first study to assess the risk of mortality in participants with comorbid insomnia and sleep apnea,” said Dr. Lechat, who led the research.
“Since these people are at higher risk for health problems, it is important that people screened for one disorder are screened for the other as well. “
While more research is needed to determine what may be causing the higher risk of death for people with COMISA, researchers say more research is also needed to ensure that treatments work effectively.
“Specific treatments may be needed for people with concurrent disorders, so it is important that we examine the effectiveness of treatments for insomnia and sleep apnea in this specific population,” said Dr Lechat.
The Adelaide Institute for Sleep Health at Flinders University continues to conduct research to understand why insomnia and sleep apnea are so common and to develop more effective treatment approaches.
