Figure 1.
Adjusted mean difference in physically and mentally unhealthy days and days with activity limitation in people with and without arthritis. Results were adjusted for age, sex, dual Medicare/Medicaid eligibility, rural/urban commuting area, and Charlson Comorbidity Index. Asterisks in figure indicate significant differences in regression-adjusted means between the arthritis and nonarthritis groups at P< .001; error bars indicate 95% confidence intervals. Abbreviations: MUHD, mentally unhealthy days; PUHD, physically unhealthy days; UHD, unhealthy days.
| Condition | Adjusted Mean (95% Confidence Interval) No. of UHD | P Value | |
|---|---|---|---|
| Arthritis | No Arthritis | ||
| PUHD | 10.6 (10.0–11.2) | 8.6 (8.0–9.2) | <.001 |
| MUHD | 6.1 (5.5–6.7) | 5.6 (5.1–6.1) | <.001 |
| Activity limitation | 6.8 (6.3–7.3) | 5.4 (4.8–6.0) | <.001 |
Figure 2.
Adjusted mean difference in unhealthy days and days with activity limitation in people with a chronic condition, with and without arthritis. Results were adjusted for age, sex, dual Medicare/Medicaid eligibility, rural/urban commuting area, and Charlson Comorbidity Index. Asterisks in figure indicate significant differences in regression-adjusted means between the arthritis and nonarthritis groups at P< .001; error bars indicate 95% confidence intervals. Abbreviations: CAD, coronary artery disease; CHF, congestive heart failure; COPD, chronic obstructive pulmonary disease; HTN, hypertension; MUHD, mentally unhealthy days; PUHD, physically unhealthy days; UHD, unhealthy days.
