Mediators of Functional Disability at Mid- and Late-Life.

As the number and proportion of older adults living in the U.S. increases, growing evidence shows that people are entering late life with more functional disability than in previous generations. Using data from the 2020 Behavioral Risk Factor Surveillance System survey, we sought to identify the contributions of demographic variables and health conditions to functional disability. Specifically, we tested the associations among age, sex, race, chronic physical health conditions, depression, and functional ability among 243,693 adults, ages 45 years and older. Model testing, implemented in AMOS 29.0.0, resulted in an acceptable fit of the model to the data, Χ² (DF = 18, N = 243,693) = 19,512.64, p < .001; CFI = 0.909; TLI = 0.774; RMSEA = 0.066; R ² Function = .267. The findings from the present study replicate previous research that age, sex, and racial background differences influence functional disability. We extend the literature to examine physical and emotional health as potential pathways to intervene in midlife.
