little is known about demographic and clinical characteristics associated with sleep-disordered breathing (SDB) and obstructive sleep apnoea (OSA) or central sleep apnoea (CSA) in community-dwelling elderly. We also examined these (OSA and CSA) associations to all-cause and cardiovascular (CV) mortality.
a total of 331 community-dwelling elderly aged 71-87 years underwent a clinical examination and one-night polygraphic recordings in their homes. Mortality data were collected after seven years.
a total of 55% had SDB, 38% had OSA and 17% had CSA. Compared with those with no SDB and OSA, more participants with CSA had a left ventricular ejection fraction 75 years does not appear to be associated with cardiovascular disease (CVD) disease or mortality, whereas CSA might be a pathological marker of CVD and impaired systolic function associated with higher mortality.
The purpose of this study was to explore whether associations between self-reported sleep duration, depressive symptoms, anxiety, fatigue and daytime sleepiness differed in older community-dwelling men and women.
A community-dwelling sample of 675 older men and women (mean age 77.7 years, SD 3.8 years) was used. All participants underwent a clinical examination by a cardiologist. Validated questionnaires were used to investigate sleep duration, depressive symptoms, anxiety, fatigue and daytime sleepiness. Subjects were divided into short sleepers (=6 hours), n = 231; normal sleepers (7-8 hours), n = 338; and long sleepers (=9 hours), n = 61. ancovas were used to explore sex-specific effects.
Depressive symptoms were associated with short sleep in men, but not in women. Fatigue was associated with both short and long sleep duration in men. No sex-specific associations of sleep duration with daytime sleepiness or anxiety were found.
Nurses investigating sleep duration and its correlates, or effects, in clinical practice need to take sex into account, as some associations may be sex specific. Depressive symptoms and fatigue can be used as indicators to identify older men with sleep complaints.
