(HealthDay)—Insomnia is common in older community-dwelling adults, but usually mild, according to a study published online May 21 in the Journal of the American Geriatrics Society.

Brienne Miner, M.D., from Yale University in New Haven, Conn., and colleagues assessed insomnia in 379 older community-dwelling adults (mean age, 84.3 years; 67.8 percent female).

The researchers found that 43 percent of participants reported insomnia, although the average Insomnia Severity Index score was mild. In multivariable regression models, only depressive symptoms (adjusted odds ratio, 8.34) and restless legs syndrome (adjusted odds ratio, 2.49) were significantly associated with insomnia.
