LitCog IV: Health Literacy and Cognitive Function Among Older Adults

Project: Research project

Project Details

Description

LitCog studies the confluence of increased medical morbidity resulting in complex patient self-management (SM) roles, and cognitive decline, which may affect older patients’ health literacy (HL) skills and chronic illness self-care.Our primary aim is to 1) evaluate trajectories in cognitive function, HL and SM skills over 15 years among older adults, and their associations with health outcomes.

We now propose to conduct follow-up assessments 12 and 15 years post-baseline (LitCog IV). With 6 interviews over 15 years, specific trajectories of decline in cognition, HL, SM skills and health status can be closely studied. The prevalence of and adjustment to increasing morbidity, disability, cognitive impairment (including Alzheimer’s Disease & Related Dementias (ADRD)) allow for new outcomes for investigation. Mortality data will also now be available with extended follow-up.LitCog is an exceptionally unique cognitive aging cohort study as it is framed in the context of health services research. Our goal has been to inform health system strategies for effectively managing older patients by understanding how cognition changes and influences HL and SM skills necessary for achieving optimal health. Modifiable factors that may mediate/moderate associations are also explored as potential intervention targets. The involvement and roles of caregivers has specifically emerged as an important social determinant of patients’ health. An administrative ADRD supplement (LitCog IIIA) has expanded our inquiry by including interviews with caregivers (informal or paid) involved in supporting the care of 60% of participants. In LitCog IV, we will create a parallel caregiver cohort, with the secondary aims to 2) investigate associations between the presence of an involved caregiver with treatment adherence, chronic disease outcomes, and functional health status among older adults; 3) identify factors influencing associations between caregiver involvement and patient outcomes.
