Abstract

Abstract : Objective: Arthritis and obesity are common co‐occurring conditions that can increase disability and the risk of adverse outcomes (e.g., total knee replacement). Methods: We estimated recent obesity trends among adults with arthritis from 2009 to 2014, overall and by various sociodemographic and health characteristics using data from National Health Interview Survey, an ongoing, nationally representative, in‐person household self‐reported survey of the noninstitutionalized civilian US. A secondary aim was to examine the distribution of body mass index categories among adults with and without arthritis. Results: Obesity prevalence did not change significantly over time among middle‐aged and younger adults with doctor‐diagnosed arthritis either overall ( P = 0.925 for both groups) or by demographic and health characteristics. Among older adults with doctor‐diagnosed arthritis, the unadjusted obesity prevalence was 29.4% in 2009 and 34.3% in 2014; after adjusting for all demographic and health characteristics, there was a significant relative increase in obesity prevalence (15% [95% confidence interval 6–25]) and over time ( P = 0.001). The age‐standardized prevalence of obesity and the obesity subclasses I, II, and III among adults with doctor‐diagnosed arthritis (compared with adults without doctor‐diagnosed arthritis) was 40.3% versus 26.3%, 20.1% versus 16.4%, 10.4% versus 6.2%, and 9.8% versus 3.6%, respectively ( P < 0.001 for all 4 comparisons). Conclusion: Obesity increased significantly over time among older adults with arthritis and remains high when compared with adults without arthritis. A greater dissemination of interventions focused on physical activity and diet are needed in order to reduce adverse outcomes associated with obesity and arthritis.
