Researchers have found that people who suffer from both insomnia and obstructive sleep apnea are more likely to develop cardiovascular problems and are more likely to die than people without either . The research was published in the European Respiratory Journal.
“Insomnia and obstructive sleep apnea are the two most common sleep disorders, affecting 10 to 30 percent of the population, but people can often have both at the same time,” said Dr. Bastien Lechat from the Flinders Health and Medical Research Institute: Sleep The Health.
“Previously, little was known about the impact of comorbid insomnia and obstructive sleep apnea (COMISA), but what we did know is that health outcomes in people with both conditions are consistently worse than those without the or those with either .” alone,” Lechat added.
Now researchers at Flinders University have examined a US-based dataset of over 5,000 people to understand the risks of COMISA.
The participants, who were around 60 years old at the start of the study and 52 percent female, were followed for around 15 years, during which time 1,210 people died. The results suggested that participants with COMISA were twice as likely to have high blood pressure and 70 percent more likely to have cardiovascular disease than participants without insomnia or sleep apnea.
The study also showed that participants with COMISA had a 47 percent increased risk of death (from any cause) compared to participants without insomnia or sleep apnea, even when other factors known to increase mortality were taken into account.
“This is the first study to assess the risk of death in participants with comorbid insomnia and sleep apnea,” said Dr. Lechat, who led the research. More research is needed to examine what might be causing the higher risk of death for patients with COMISA, the researchers said.
