Healthy Sleep Linked to Lower Odds for Digestive Diseases
TOPLINE:
Healthier sleep is associated with lower odds of developing a wide range of gastrointestinal conditions, regardless of genetic susceptibility, new research revealed.
METHODOLOGY:
- Due to the widespread prevalence of sleep issues and a growing burden of digestive diseases globally, researchers investigated the association between sleep quality and digestive disorders in a prospective cohort study of 410,586 people in the UK Biobank.
- Five individual sleep behaviors were assessed: Sleep duration, insomnia, snoring, daytime sleepiness, and chronotype.
- A healthy sleep was defined as a morning chronotype, 7-8 hours of sleep duration, no self-reported snoring, never or rare insomnia, and a low frequency of daytime sleepiness, for a score of 5/5.
- The study investigators tracked the development of 16 digestive diseases over a mean period of 13.2 years.
- As well as healthy sleep scores, researchers considered genetic susceptibility to gastrointestinal conditions.
TAKEAWAY:
- Participants with a healthy sleep score had 28% lower odds of developing any digestive disease (hazard ratio [HR], 0.72; 95% CI, 0.69-0.75) than those with a sleep score of 0/1.
- Of the 16 digestive diseases looked at, the reduction of risk was highest for irritable bowel syndrome at 50% (HR, 0.50; 95% CI, 0.45-0.57).
- A healthy sleep score was also associated with a 37% reduced odds for metabolic dysfunction-associated steatotic liver disease (formerly known as nonalcoholic fatty liver disease; HR, 0.63; 95% CI, 0.55-0.71), 35% lower chance for peptic ulcer (HR, 0.65; 95% CI, 0.058-0.74), 34% reduced chance for dyspepsia (HR, 0.66; 95% CI, 0.58-0.75), and a 25% lower risk for diverticulosis (HR, 0.75; 95% CI, 0.71-0.80).
- High genetic risk and poor sleep scores were also associated with increased odds (53% to > 200%) of developing digestive diseases.
- However, healthy sleep reduced the risk for digestive diseases regardless of genetic susceptibility.
IN PRACTICE:
"Our findings underscore the potential holistic impact of different sleep behaviors in mitigating the risk of digestive diseases in clinical practice," wrote Shiyi Yu, MD, of Guangdong Provincial People's Hospital, Guangzhou, Guangdong, China, and colleagues.
Poor sleep can also change our gut microbiome, Yu told Medscape Medical News. If you don't sleep well, the repair of the gut lining cannot be finished during the night.
