Insomnia disorder (ISSD) with short objective sleep duration is associated with significantly increased odds of developing stroke and heart disease compared to people with normal sleep duration, according to research published today. . Journal of Clinical Sleep Medicine.

Recent research shows that sleep is an important factor for cardiovascular health. Although insomnia is consistently associated with negative health outcomes and functional impairment, relatively little is known about ISSD. ISSD is considered to be a severe phenotype of persistent, unremitting insomnia. Therefore, researchers conducted a study to examine the risk of developing cardiovascular disease (CVD) and/or cerebrovascular disease (CBVD) in ISSD patients.

Data for this study were collected as part of a population-based study of sleep disorders in the Penn State adult cohort. All study participants were evaluated overnight in a sleep laboratory and continuously monitored for 8 hours by 16-channel polysomnography. Participants also completed a standardized questionnaire assessing insomnia and the presence of CVD and/or CBVD at baseline during a sleep laboratory visit. Researchers categorized participants into three cohorts based on self-reported sleep difficulties: normal sleep, sleep deprivation (moderate to severe complaints), and chronic insomnia (insomnia complaints lasting more than 1 year). ). In addition, the researchers conducted follow-up telephone interviews to determine the occurrence of CVD and/or CBVD.

A total of 1,258 participants were included in the analysis, of which 73.4% reported normal sleep, 19.7% reported sleep deprivation, and 6.8% chronic insomnia. Participants’ mean age was 48.3 (SD, 12.95) years, 52.1% were female, and 91.4% were Caucasian. At follow-up, the overall incidence of CVD and/or CBVD was 16.3% (n=206).

Compared to normal sleepers who slept more than 6 hours, people with insomnia who objectively slept less than 6 hours were more likely to develop CVD and/or CBVD (odds ratio) [OR], 2.69; 95% CI, 1.18-6.17). Furthermore, normal sleepers who slept less than 6 hours also had increased odds of developing CVD and/or CBVD compared with normal sleepers who slept less than 6 hours (OR, 1.65; 95 % CI, 1.10-2.49). Among participants with insomnia who subjectively reported sleeping less than 7 hours, there was no increased risk of developing CBVD (OR, 1.57; 95% CI, 0.71-3.44).

These results demonstrate that insomnia with short objective rather than subjective sleep duration is associated with a significantly increased risk of CBD and/or CBVD compared to individuals with normal sleep duration. It shows that. “These findings provide further support that the ISSD phenotype, based on objective rather than subjective measures, is associated with an increased risk of developing heart disease and stroke in adults,” the researchers wrote. concluded.

These findings depend on self-reported patient history of CVD and/or CBVD, the precise timing of cardiovascular disease onset cannot be determined, and only one night of sleep data is available, which is representative. It may be limited due to the fact that it may not be a real thing. Habitual sleep patterns.
