The independent influence of anxiety on insomnia and sleepiness in older adults.

摘要

Lack of sleep may be caused by a variety of factors, leading to diminished quality of life. In this study, 71 older adults from assisted-living communities participated in structured interviews with several instruments. Anxiety (beta = .38, p .01) and perceived activity level (beta = -0.43, p .01) were significant predictors of insomnia, which may represent meaningful targets for insomnia treatment in this population. Other results indicate a significant independent relationship exists between anxiety and insomnia (r = .32, p .01), when controlling for depression and other factors. Insomnia and sleepiness were not significantly correlated (r = .01, p = .48), indicating they are separate constructs. Men were found to suffer with sleepiness more than women.
