Description:Introduction
Arthritis and obesity are common co-occurring conditions which can increase disability and 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 U.S. A secondary aim was to examine the distribution of body mass index (BMI) 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-trend=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% CI: 6–25)) and over time (p-trend=0.001). The 2014 distribution of BMI categories for adults with doctor-diagnosed arthritis (compared with adults without doctor-diagnosed arthritis) was skewed toward the obese category and its subclasses, but there were no significant changes in these relationships from 2009.
Conclusions
Obesity increased significantly over time among older adults with arthritis and remains high when compared with adults without arthritis. Greater dissemination of interventions focused on physical activity and diet are needed to reduce the adverse outcomes associated with obesity and arthritis.
