  • Data are odds ratios (95% confidence intervals). Logistic regressions were adjusted for the following personal characteristics: age, race, sex, insurance, metropolitan statistical area, census region, perceived health status, perceived mental health status, activities of daily living, and instrumental activities of daily living.

  • * P < .05 based on test of significance of the odds ratios.

  • USC, usual source of care.
