People living with dementia receive care from multiple caregivers, but little is known about the structure of their caregiving arrangements. This study used the Health and Retirement Study and latent class analyses to identify subgroups of caregiving arrangements based on caregiving hours received from spouses, children, other family/friends, and paid individuals among married (n = 361) and unmarried (n = 473) community-dwelling people with probable dementia. Three classes in the married sample (class 1 "low hours with shared care," class 2 "spouse-dominant care," and class 3 "children-dominant care") were identified. In class 1, spouses, children, and paid individuals provided 53%, 22%, and 26% of the caregiving hours, respectively. Three classes in the unmarried sample (class 1 "low hours with shared care," class 2 "children-dominant care," and class 3 "paid-dominant care") were identified. In unmarried class 1, children, other family/friends, and paid individuals provided 35%, 41% and 24% of the caregiving hours, respectively.

BACKGROUND: To reduce the increasing societal and financial burden of Alzheimer's disease and related dementias (ADRD), prevention is critical. Even small improvements of the modifiable dementia risk factors on the individual level have the potential to lead to a substantial reduction of dementia cases at the population level.

OBJECTIVE: To determine if pattern(s) of functional decline in midlife associate with late-onset ADRD years later.

METHODS: Using a longitudinal study of adults aged 51-59 years in 1998 without symptoms of ADRD by 2002 and followed them from 2002 to 2016 (n = 5404). The outcome was incident ADRD identified by the Lange-Weir algorithm, death, or alive with no ADRD. We used cluster analysis to identify patterns of functional impairment at baseline and multinomial regression to assess their association with future ADRD.

RESULTS: Three groups of adults with differing patterns of functional impairment were at greater risk of future ADRD. Difficulty with climbing one flight of stairs was observed in all adults in two of these groups. In the third group, 100% had difficulty with lifting 10 pounds and pushing or pulling a large object, but only one-fourth had difficulty in climbing stairs.

CONCLUSION: Results imply that improved large muscle strength could decrease future risk of ADRD. If confirmed in other studies, screening for four self-reported measures of function among adults in midlife may be used for targeted interventions.
