Highlights
- •The more intrinsic capacity impairments an older person has, the higher is the risk of incident frailty and incident disability.
- •Limited mobility, vision impairment and depressive symptoms are predictors of functional decline.
- •The ICOPE Step1 screening tool can detect people at higher risk of functional decline.
Abstract
Aim
This longitudinal secondary analysis of the Multidomain Alzheimer Preventive Trial
(MAPT) aimed to test whether the Integrated Care for Older People (ICOPE) Step 1 screening
tool is able to identify people at risk of developing frailty and disability in basic
(ADL) and instrumental (IADL) activities of daily living among community-dwelling
older adults.
Participants and setting
Seven hundred and fifty-nine (n = 759) non-demented participants of the MAPT aged 70–89 years were assessed in memory
clinics in France between 2008 and 2013.
Methods
We measured six intrinsic capacity (IC) impairments, adapted from the ICOPE screening
tool. We used Cox models to estimate the adjusted hazard ratios of incident frailty
and IADL/ADL disability. Incident frailty was defined by Fried's phenotype, and incident
disability was measured according to Lawton and Katz for IADLs and ADLs.
Results
Limited mobility (HR= 2.97, 95%CI= 1.85–4.76), depressive symptoms (HR= 2.07, 95%CI=
1.03–4.19), and visual impairment (HR= 1.70, 95%CI 1.01–2.86) were associated with
a higher incidence of frailty over 5 years. Each additional IC condition demonstrated
a positive association with a higher risk of incident frailty, IADL, ADL disability,
with risk increased by 47%, 27%, and 23% over 5 years, respectively.
Conclusion
Screening for IC impairments identifies older adults at higher risk of incident frailty
and incident IADL/ADL disability. It is relevant to screen for these impairments together
because the risk of frailty and disability increases with each additional one.
