Longitudinal and reciprocal associations between financial strain, home characteristics and mobility in the National Health and Aging Trends Study

Table 3 Cross-lagged and autoregressive associations between financial strain, home disorder, relocating and modifying home and walking speed (m/s) among community-dwelling National Health and Aging Trends Study participants followed from 2012 to 2014 and able to complete the walking test in 2014 (n = 2467)

Note: Adjusted for baseline age, age-squared, sex, black race, Hispanic ethnicity, education and income and one-year lagged values of financial strain, home disorder, relocating, modifying home and walking speed in a structural equation model with good fit (RMSEA = 0.027). Unstandardized coefficients are presented. Cross-lagged associations were constrained across study years. 2014 sampling weights were used
^a Additionally adjusted for presence of social support
^b Additionally adjusted for two-year lagged values of height, chronic conditions and BMI
