Abstract
OBJECTIVE: Arthritis patients experience the impact of disease beyond routinely assessed clinical measures. We characterized arthritis-attributable interference in four important routine life domains: 1) recreation/leisure/hobbies; 2) household chores; 3) errands/shopping; and 4) social activities. METHODS: Participants were from the Arthritis Conditions Health Effects Survey (2005-2006), a cross-sectional survey of noninstitutionalized US adults 45 years or older with doctor-diagnosed arthritis (n = 1793). We estimated the prevalence of "a lot" of arthritis-attributable interference and quantified the associations between sociodemographic, clinical, and psychological characteristics and "a lot" of arthritis-attributable interference (vs "a little" or "none") in each domain using prevalence ratios (PRs) in multivariable (MV)-adjusted logistic regression models. RESULTS: An estimated 1 in 5 to 1 in 4 adults with arthritis reported "a lot" of arthritis-attributable interference in recreation/leisure/hobbies (27%), household chores (25%), errands/shopping (22%), and social activities (18%). The highest prevalence of "a lot" of arthritis-attributable interference was for those unable to work/disabled or reporting severe arthritis symptoms (pain, stiffness, fatigue), anxiety, depression, or no/low confidence in ability to manage arthritis, across domains. In MV-adjusted models, those unable to work/disabled, currently seeing a doctor, or reporting fair/poor self-rated health, severe joint pain, anxiety, or no/low confidence in ability to manage arthritis were more likely to report arthritis-attributable interference than their respective counterparts. Magnitudes varied by domain but were consistently strongest for those unable to work/disabled (MV PR range = 1.8-2.5) and with fair/poor health (MV PR range = 1.7-2.7). CONCLUSION: Many characteristics associated with arthritis-attributable interference in routine life activities are potentially modifiable, suggesting unmet need for use of existing evidence-based interventions that address these characteristics and reduce interferences to improve quality of life.
