Updated Projected Prevalence of Self-Reported Doctor-Diagnosed Arthritis and Arthritis-Attributable Activity Limitation Among US Adults, 2015-2040.

To update the projected prevalence of arthritis and arthritis‐attributable activity limitations among US adults, using a newer baseline for estimates.

Vital Signs: Prevalence of Doctor-Diagnosed Arthritis and Arthritis-Attributable Activity Limitation — United States, 2013–2015

Background In the United States, doctor-diagnosed arthritis is a common and disabling chronic condition. Arthritis can lead to severe joint pain and poor physical function, and it can negatively affect quality of life. Methods CDC analyzed 2013–2015 data from the National Health Interview Survey, an annual, nationally representative, in-person interview survey of the health status and behaviors of the noninstitutionalized civilian U.S. adult population, to update previous prevalence estimates of arthritis and arthritis-attributable activity limitations. Results On average, during 2013–2015, 54.4 million (22.7%) adults had doctor-diagnosed arthritis, and 23.7 million (43.5% of those with arthritis) had arthritis-attributable activity limitations (an age-adjusted increase of approximately 20% in the proportion of adults with arthritis reporting activity limitations since 2002 [p-trend <0.001]). Among adults with heart disease, diabetes, and obesity, the prevalences of doctor-diagnosed arthritis were 49.3%, 47.1%, and 30.6%, respectively; the prevalences of arthritis-attributable activity limitations among adults with these conditions and arthritis were 54.5% (heart disease), 54.0% (diabetes), and 49.0% (obesity). Conclusions and Comments The prevalence of arthritis is high, particularly among adults with comorbid conditions, such as heart disease, diabetes, and obesity. Furthermore, the prevalence of arthritis-attributable activity limitations is high and increasing over time. Approximately half of adults with arthritis and heart disease, arthritis and diabetes, or arthritis and obesity are limited by their arthritis. Greater use of evidence-based physical activity and self-management education interventions can reduce pain and improve function and quality of life for adults with arthritis and also for adults with other chronic conditions who might be limited by their arthritis.

Obesity Trends Among Adults with Doctor-Diagnosed Arthritis- United States, 2009-2014.

Arthritis and obesity are common co‐occurring conditions that can increase disability and the risk of adverse outcomes (e.g., total knee replacement).

Self‐Management Education Participation Among US Adults With Arthritis: Who's Attending?

Self‐management education (SME) programs teach people with chronic conditions skills to manage their health conditions. We examined patterns in SME program participation among US adults with arthritis ages ≥18 years.

Prevalence of Severe Joint Pain Among Adults with Doctor-Diagnosed Arthritis - United States, 2002-2014.

In the United States, arthritis is a leading cause of disability (1,2); arthritis affected an estimated 52.5 million (22.7%) adults in 2010-2012 and has been projected to affect 78.4 million adults by 2040 (3). Severe joint pain (SJP) can limit function and seriously compromise quality of life (4,5). To determine the prevalence of SJP among adults with doctor-diagnosed arthritis, and the trend in SJP from 2002 to 2014, CDC analyzed data from the National Health Interview Survey. In 2014, approximately one fourth of adults with arthritis had SJP (27.2%). Within selected groups, the age-standardized prevalence of SJP was higher among women (29.2%), non-Hispanic blacks (42.3%), Hispanics (35.8%), and persons with a disability (45.6%), and those who were unable to work (51.9%); prevalence also was higher among those who had fair or poor health (49.1%), obesity (31.7%), heart disease (34.1%), diabetes (40.9%), or serious psychological distress (56.3%). From 2002 to 2014, the age-standardized prevalence of SJP among adults with arthritis did not change (p = 0.14); however, the number of adults with SJP was significantly higher in 2014 (14.6 million) than in 2002 (10.5 million). A strategy to improve pain management (e.g., the 2016 National Pain Strategy*) has been developed, and more widespread dissemination of evidence-based interventions that reduce joint pain in adults with arthritis might reduce the prevalence of SJP.

Education and Employment Participation in Young Adulthood: What Role Does Arthritis Play?

To examine the association between arthritis diagnosis and education and employment participation among young adults, and to determine whether findings differ by self‐rated health and age.

Leisure Time Physical Activity Among U.S. Adults With Arthritis, 2008−2015

INTRODUCTION In 2016, leisure time physical activity among U.S. adults aged ≥18 years with and without arthritis was studied to provide estimates using contemporary guidelines (2008 Physical Activity Guidelines for Americans) and population-based data (U.S. National Health Interview Survey). METHODS Estimated prevalence of: (1) meeting aerobic, muscle strengthening, and both aerobic and muscle strengthening guidelines, by arthritis status, from 2008 to 2015; and (2) meeting guidelines across selected sociodemographic characteristics and health status and behaviors, among adults with arthritis, in 2015. RESULTS In 2015, 36.2%, 17.9%, and 13.7% of adults with arthritis met aerobic, muscle strengthening, and both guidelines, respectively; age-standardized prevalence of meeting each guideline was significantly lower among those with arthritis versus those without (e.g., 41.9% [95% CI=39.5%, 44.3%] and 52.2% [95% CI=51.2%, 53.2%] met the aerobic guideline, respectively; p<0.001). From 2008 to 2015, meeting aerobic guideline rose modestly (3 percentage points) among those with arthritis compared with larger gains (7 percentage points) among those without arthritis; the percentage of adults with arthritis meeting muscle strengthening and both guidelines remained the same in contrast to modest (statistically significant) increases among those without arthritis. Among adults with arthritis, age-standardized percentage meeting each guideline was highest among those with at least a university degree. CONCLUSIONS Percentage meeting each guideline was persistently low among adults with arthritis. The lower prevalence among adults with arthritis versus those without suggests that adults with arthritis need additional strategies to address potential barriers (e.g., pain, psychological distress, inadequate medical support) to physical activity.
