Проведенные ранее исследования уже определили, что бессонница связана с риском преждевременной смерти. Новое исследование, выполненное на базе Университета Аризоны, более подробно изучило связь между этим риском и разными формами бессонницы. Было выявлено, что постоянная форма нарушения сна несет для человека большую угрозу, чем эпизодическая.
Исследователи проанализировали данные 1409 взрослых пациентов, принявших участие в эпидемиологическ
Анализ данных показал, что постоянная бессонница связана с увеличением риска преждевременной смерти на 58%. Более того, было выяснено, что конкретные причины смерти связаны главным образом с сердечно-сосудис

Persistent insomnia linked to higher risk of death, study finds
А 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. Researchers from the University of Arizona in Tucson sought to clarify if the link between insomnia and raised risk of premature death depended on the type of insomnia. They also looked at whether there was a difference in inflammation.
For their study, Prof. Parthasarathy — who is also director of the Center for Sleep Disorders at the University of Arizona Medical Center — and colleagues examined data from 1,409 adults who took part in the Tucson Epidemiological Study of Airway Obstructive Disease (TESAOD). Participants were enrolled in 1972 and surveyed and examined until 1996. After that, deaths in the group continued to be monitored until 2011, making a total study period of 38 years.
The team put the participants into one of three categories:
- Persistent insomnia — insomnia was present in both questionnaires completed in 1984-1985 and 1990 -1992
- Intermittent insomnia — insomnia was present in either but not both questionnaires
- Never insomnia — insomnia was not present in either questionnaire.
After taking the potential confounders into account, they found that participants with persistent insomnia had a 58% higher chance of dying during the study than participants in the never insomnia group. The results also indicated that the excess deaths in the persistent insomnia group were due to cardiopulmonary factors rather than cancer.
While members of the intermittent insomnia group appeared to have a higher risk of dying in the study period than those of the never insomnia group, the researchers found this risk went away when they adjusted for factors such as weight, smoking status and exercise. From the blood sample analysis, the team also found that levels of C-reactive protein (CRP) — a measure of inflammation that is also an independent risk factor for mortality — were higher in the persistent insomnia group.
