Persistent Insomnia Increases Premature Death Risk

People with persistent insomnia have a higher risk of premature death than those with intermittent or no insomnia, according to a new study from the University of Arizona in Tucson.

Previous studies have linked insomnia to an increased risk of premature death, but the researchers in this study wanted to see if the risk differed between persistent and intermittent insomnia as well.

The study included 1,409 participants from the Tucson Epidemiological Study of Airway Obstructive Disease (TESAOD). The TESAOD surveyed patients from 1972 through 1996, and participants were monitored for deaths until 2011.

Each participant was surveyed about their sleep habits twice: once between 1984 and 1985 and once between 1990 and 1992. Based on their responses, the researchers sorted them into three categories: persistent insomnia (insomnia present in both surveys), intermittent insomnia (insomnia present in only one survey), or no insomnia (insomnia not present in either survey).

After adjusting for variables, the researchers found that those with persistent insomnia were 58% more likely to have died during the study period than those with no insomnia. They noted that the additional deaths in the persistent insomnia group came from cardiopulmonary factors.

Those with persistent insomnia also had higher levels of C-reactive protein (CRP) compared with those in the never insomnia group. Even after adjusting for the increased risk of death that comes with raised CRP levels, the persistent insomnia group still had a 36% increased risk of death compared to those with no insomnia.

Persistent Insomnia Increases Premature Death Risk

A new study that examines the link between insomnia and raised risk of premature death concludes that persistent insomnia poses a greater risk than intermittent insomnia.

While previous studies have already shown links between insomnia and increased risk of premature death, they have not clarified whether the risk differs between persistent and intermittent insomnia.

Intermittent or acute insomnia is of short duration and often linked to specific events - for instance, not being able to fall asleep the night before an exam or an important job interview.
