OBJECTIVE: To determine the factors that predict change in wellbeing, over time among older men and women presenting to the Vancouver Falls Prevention Clinic.
DESIGN: 12-month prospective cohort study SETTING: Vancouver Falls Prevention Clinic PARTICIPANTS: The study sample consisted of between 244 - 255 (depending on the analysis) community-dwelling older adults referred to the clinic after suffering a fall. MAIN OUTCOME MEASURE: The ICECAP-O, a measure of wellbeing/quality of life, was administered at baseline, 6-months, and 12-months. We constructed linear mixed models to determine whether baseline predictor variables were related to baseline wellbeing and/or changes in wellbeing over time. Additionally, we included interactions with sex to investigate difference for males versus females. Baseline predictors included two measures of mobility (Short Performance Physical Battery (SPPB) and Timed Up and Go (TUG)) and a measure of global cognitive function (Montreal Cognitive Assessment (MoCA)).
RESULTS: All three predictors were associated with wellbeing at baseline (p<0.05). Further, both SPPB and TUG interacted with sex (p<0.05) to predict changes in wellbeing over time. Follow-up analyses suggested that better mobility was protective against decline in wellbeing in males but was generally unrelated to changes in wellbeing in women.
CONCLUSION: We found that two valid and reliable measures of mobility interacted with sex to predict changes in wellbeing overtime. This is a critical research area to develop in order to appropriately tailor future intervention strategies targeting wellbeing among older fallers - a population at high risk of functional decline.
