A Concordance of Self-reported and Performance-based Assessments of Mobility as a Mortality Predictor for Older Mexican Americans *
ABSTRACT
AIM: To assess the efficacy in mortality prediction of a concordance of performance-based (timed 10-foot walk {POMA}) and self-rated (reported ability to walk across a small room with no help from people or devices {ADL}) assessments of mobility for Mexican Americans aged 75 and over.
Methods: Longitudinal study of 2069 subjects aged 75 years and older from the Hispanic Established Population for the Epidemiological Study of the Elderly (EPESE) Wave 5 (2004–06 ~ 2006–01) and Wave 6 (2007–02 ~ 2008–02). Sociodemographic variables, performance-based (timed 10-foot walk) and self-rated assessments (reported ability to walk across a small room without any people or device’s help) of mobility, and mortality data were obtained.
Results: The ADL/POMA concordance assessment revealed a prevalence of the “positively concordant” group (completed the walk and reported being able to walk, ADL and POMA both positive), followed by the “pessimist,” “optimist,” and “negatively concordant” groups at 80.09%, 10.50%, 3.78%, and 5.63% respectively. Logistic regression analyses showed that “negatively concordant” was a critical mortality predictor (OR=4.80; 95% CI =2.59 - 8.90) followed by “pessimist” (OR=1.94; 95% CI=1.12 - 3.36) as compared to the reference group, “positively concordant.”
Conclusion: The ADL/POMA concordance is an effective predictor of mortality for older Mexican Americans in the Hispanic EPESE.
