Does sleep disturbance predict depression in elderly people? A study in inner London

Topic: Health services, long-term care and technology
Insomnia in elderly people has traditionally been regarded as inevitable and trivial. A longitudinal study was undertaken to examine the prevalence of sleep disturbance among elderly people in an inner London community and its association with demographic variables, depression, dementia and disability. Those aged 65 years and over living at home were interviewed using a validated and reliable semi-structured interview schedule. A total of 705 people were interviewed in 1987-88 and 524 were re-interviewed in 1990. Subjective sleep disturbance was found to be common (33% and 43%, respectively). Sleep disturbance was associated with being a woman, being unmarried, living alone, disability, and current and future depression, but not with dementia or older age. The best predictor of future depression in elderly people who were not depressed was current sleep disturbance. In the presence of current sleep disturbance, the traditional predictors of depression--being a woman, having a disability, being unmarried, living alone and being older--did not contribute further. This study has shown that sleep disorder is associated with pathology. Insomnia in elderly people requires assessment and this must be accompanied by the treatment of underlying disorders and monitoring of future health.
Key findings
- Sleep disturbance was associated with being a woman, being unmarried, living alone, disability, and current and future depression, but not with dementia or older age.
- This study has shown that sleep disorder is associated with pathology.

How this study scored 64/100
Published in a peer-reviewed journal, and it is a longitudinal study following the same people over time. Scored zero for effect reported and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 37 of the 58 points we could judge it on, which is 64 out of 100.
