A Community-Based Collaborative Care Model to Improve Functional Health in Underserved Community-Dwelling Older Adults.

Objective: Examine the effects of a 6-month health multidimensional intervention on physical function, bone density, and mood in a diverse sample of community-dwelling older adults at risk for frailty and excess disability.

Method: A quasi-experimental, pre- post-program design was implemented. Adults aged 55 years and older ( n = 337, 60% African American) participated in the intervention and received assessments at baseline, 6 months, and 12 months.

Results: Physical function was maintained during the intervention for both African American and White elders but declined at 12 months for both groups ( p < .0001). Symptoms of depression improved during the intervention ( M = 0.65 ± 0.07, M = 0.15 ± 0.04, M = 0.68 ± 0.07, p < .001, respectively) but worsened at 12 months ( M = 0.68 ± 0.07, p < .001). Bone density scores remained stable from baseline (distal: -1.62 ± 1.17, proximal: -2.73 ± 1.85) to 12 months (distal: -1.72 ± 1.21, proximal: -3.11 ± 1.85, ps > .05) for both groups.

Discussion: Program findings may serve as a basis for the development of a randomized, controlled study to provide empirical evidence of intervention efficacy. Such findings may help inform the development of community-based programs to identify vulnerable older adults and provide vital preventative care to decrease frailty and excess disability.
