The aims of this project were to determine the prevalence of subjective sleep difficulties in community-dwelling older fallers, and to evaluate the relationship between subjective sleep quality and falls.  Cross-sectional and longitudinal analyses of data from a randomised controlled trial (Falls Aren’t Us study) were undertaken. The original study evaluated a multi-factorial falls prevention program for community-dwelling older people presenting to an emergency department after a fall. Sleep quality was assessed using the sleep item of the Assessment of Quality-of-Life scale, and falls data was collected prospectively. A causal diagram was generated to establish covariates to Sleep quality was assessed using the sleep item of the Assessment of Quality-of-Life scale, and falls data was collected prospectively. A causal diagram was generated to establish covariates to include in the analysis. No independent effect of sleep quality on falls rate was found; however, there was a trend towards those who report waking occasionally to have a lower falls rate than those report not waking at all. This could reflect a threshold effect of sleep interruption on falls or a “survivor” bias.
