Association Between Activities of Daily Living Profiles and Memory Decline in Community-Dwelling Older Adults Without...

To explore baseline activities of daily living (ADL) profiles and their association with memory decline over time in cognitively healthy, community-dwelling older adults.

Observational panel study.

This study analysed data from Waves 7-10 of the English Longitudinal Study of Ageing (the search was performed on May 28, 2024), including 2925 older adults aged above 65 with no dementia or cognitive impairments at baseline (Wave 7, 2014-2015). To categorise participants by their daily functional abilities at baseline, latent class analysis was conducted to derive participants' activities of daily living profiles. A linear mixed model was used to explore whether these baseline activity profiles might predict different memory decline rates (trajectories) over time, accounting for baseline demographic factors (gender, age, ethnicity, education, marital status and chronic diseases).

Social demographics (younger age, female gender, white ethnicity, higher education and being partnered) and ADL profiles outweigh health conditions in predicting participants' memory function. Different baseline profiles were linked to different memory decline trajectories. An impairment profile with grocery shopping capability was linked to slower memory decline.

This study showed that ADL profiles had a substantial correlation with memory decline, accounting for the significant impact of sociodemographic factors. An impairment profile that preserved grocery shopping abilities appeared to offer protective benefits and potentially slow memory decline.

Strengthening nursing strategies that support older adults in maintaining the ability to grocery shop, such as guiding caregivers to promote involvement rather than shopping for the older adults entirely, or accompanying older adults grocery shopping as part of community nursing care, might help delay age-related memory decline in this population.

Patients or members of the public were not directly involved in the study's design, conduct, reporting, or dissemination plans.
