title: Relationship between depression and physical activity, disability, burden, and health-related quality of life among patients with arthritis.
abstract: This study purports to examine the relationship of depression with physical activity, disability, arthritis-attributable burden (joint limitation, work limitation, social activity limitation, and joint pain), and health-related quality of life (HRQOL) among arthritis patients. Data from the 2011 Behavioral Risk Factor Surveillance System, a nationally representative sample of noninstitutionalized adults in the United States, was used for the purpose of this study. Multivariable logistic regression was employed to address the study objectives. The final study sample included 167,068 arthritis patients, 45,459 of whom had comorbid depression. Arthritis patients with depression had lower odds of engaging in physical activity (odds ratio [OR]=1.070, confidence interval [CI] 1.006-1.139) and higher odds of being disabled (OR=1.411, CI 1.306-1.524). Arthritis patients with depression also had greater odds of arthritis-attributable joint limitations (OR=1.551, CI 1.460-1.648), work limitations (OR=1.506, CI 1.414-1.604), social activity limitations (OR=1.647, CI 1.557-1.742), and pain (OR=1.438, CI 1.364-1.517) as compared to those without depression. Arthritis patients with versus without depression had greater odds of poor general health status (OR=1.698, CI 1.586-1.819), physical HRQOL (OR=1.592, CI 1.486-1.704), mental HRQOL (OR=6.225, CI 5.768-6.718), and activity limitations (OR=2.345, CI 2.168-2.537). Study results indicate toward a negative functional impact of depression among arthritis patients. Policy makers should consider incorporating screening and management of depression into routine clinical care of arthritis patients.
