Note. OR = odds ratio; CI = confidence interval. Boldface indicates comparisons in which the 95% confidence interval excludes no effect (i.e., conventional statistical significance). All results are weighted to account for oversampling of African Americans, Asians/Pacific Islanders, Latinos, persons with disabilities, and persons aged 45 to 70 years. For explanation of geriatric depression score, see Methods section.

^aMultiple logistic regression analysis controlling for age, sex, race, educational attainment, smoking status (current and ex-smoker), and low income. Referent group is subjects with other chronic health conditions (first 2 columns) or asthma (last column). Confidence intervals are adjusted for multiple comparisons using the Bonferroni method.
