Note. Data weighted according to the NSOC weight. Variables presented in this table reached a significance value of p <.20 in bivariate analyses and were used in the multivariable model.

^aP-values obtained using unadjusted logistic regression.

^bInstrumental/activities of daily living-related is comprised of six tasks; health management is comprised of five tasks; health systems logistics is comprised of five tasks.

OR = odds ratio. CI = confidence interval.
