Men and women in their 80s and 90s sleep less and have poorer quality sleep than young individuals, but they are also less likely to report feeling unrested or overly sleepy the next day, investigators report in the Journal of the American Geriatrics Society.
"This study is novel in part due to the sheer size and scope of the study compared to earlier works," first author Dr. Mark L. Unruh noted in correspondence with Reuters Health. By studying older individuals still living in the community, the results may be generalized to the majority of older adults.
Unruh's group designed the study to determine whether "sleep problems in older adults should be addressed by treating underlying conditions rather than viewed as simply a consequence of aging." The study included 5,407 subjects who completed a sleep questionnaire and underwent a home sleep study.
According to Unruh, at the University of Pittsburgh Medical Center, and co-investigators, the sleep test, or "polysomnography," showed that the total average nightly sleep time declined from 386 minutes among women in their 40s to 341 minutes among those 80 years of age or older. In men, the corresponding sleep times declined from 361 minutes to 326 minutes.
