INTRODUCTION: Arthritis is a common chronic disease, affecting an estimated 53.2 million adults (21.2%) in the US. "Arthritis" is a general term, describing over 100 conditions with different etiologies, pathogeneses, symptoms, and treatments. Few studies have examined the prevalence and distribution of arthritis subtypes in the US. METHODS: We used National Health and Nutrition Examination Survey data from 2017 to March 2020 to estimate the prevalence of arthritis subtypes overall and by sociodemographic characteristics. RESULTS: The overall prevalence of any type of diagnosed arthritis among US adults aged 20 years or older in this study was 27.9% (67.1 million). Among adults with diagnosed arthritis, osteoarthritis (49.6%, 33.2 million) was the most common arthritis subtype, followed by rheumatoid arthritis (15.8%, 10.6 million) and psoriatic arthritis (1.4%, 1.0 million). More than 1 in 10 reported some other type of unlisted arthritis (11.5%, 7.7 million), and 1 in 5 did not know their arthritis subtype (21.6%, 14.4 million). Prevalence of not knowing arthritis type was approximately 1 in 4 for adults identifying as non-Hispanic Black (26.7%) or other Hispanic (29.5%) and for adults who reported low family income (26.7%) and was approximately 1 in 3 for adults identifying as Mexican American (31.9%), having less than a high school education (31.8%), or not having health insurance (36.1%). CONCLUSION: Understanding arthritis type is important for improving treatment, self-management, and health outcomes associated with arthritis. Improving organizational and personal health literacy are potential strategies that may reduce the prevalence of not knowing arthritis type.

INTRODUCTION: Little is known about the recency, correlates, and content of health care provider (HCP) counseling about physical activity (PA) among adults with arthritis. METHODS: We analyzed data from the Porter Novelli FallStyles cross-sectional survey of noninstitutionalized US adults. Among adults with arthritis, we assessed the recency of HCP counseling about PA; counseling content, including PA assessment/screening and advice/counseling; and recommendations. Data were weighted by sex, age, household income, race and ethnicity, household size, education, census region, and metropolitan status. RESULTS: Among adults with arthritis (n = 1,113), 16.8% received HCP counseling within the past 6 months, 9.6% received counseling between 6 months and a year ago; 27.7% received HCP counseling more than a year ago; 30.4% never received HCP counseling; and 15.5% did not recall. Prevalence of HCP counseling about PA was higher for those reporting obesity (prevalence ratio [PR] = 1.3) and chronic pain (PR = 1.2), compared with those without these conditions. The most and least common content of HCP counseling were assessment of PA level (74.7%) and receiving a physical activity prescription (6.1%), respectively. The most frequent recommendations for PA type were flexibility exercises (40.1%), aerobic activities (39.8%), specific modalities of PA (eg, swimming, walking, dancing; 38.1%), and muscle-strengthening exercises (36.6%). Only 4.4% received a recommendation for arthritis-appropriate PA programs. CONCLUSION: HCP counseling about PA among adults with arthritis for arthritis symptom management is lacking in frequency, actionable content, and recommendations to engage in evidence-based PA interventions. Dissemination and implementation of policies and programs facilitating frequent high-quality HCP counseling and recommendation to PA programs for arthritis remains a public health priority.

OBJECTIVE: This study examined the racial/ethnic differences in self-reported doctor-diagnosed arthritis, severe joint pain, and provider counseling for physical activity among US adults with arthritis. METHODS: We estimated prevalence by race/ethnicity among 31,997 adults aged ≥18 years in the 2019 National Health Interview Survey. We used multiple logistic regression models to investigate associations between outcomes and race/ethnicity. RESULTS: Compared with non-Hispanic White adults (22.9%), we found a significantly higher age-adjusted prevalence of arthritis among American Indian/Alaska Native adults (30.3%). Among adults with arthritis, higher age-adjusted prevalence of severe joint pain among American Indian/Alaska Native (39.1%), non-Hispanic Black (36.4%), and Hispanic adults (35.7% versus 22.5% [White]) and higher provider counseling for physical activity among non-Hispanic Black adults (58.9% versus 52.1% [White]) were observed and could not be fully explained by differences in socioeconomic factors, body mass index, depression history, and comorbid conditions. Additional models also containing inability to pay medical bills and food insecurity did not explain racial/ethnic differences. CONCLUSIONS: Our findings highlight a need for multi-level interventions to mitigate social and environmental barriers to physical activity and eliminate disparities in arthritis and severe joint pain.

Arthritis is a chronic inflammatory condition and a leading cause of chronic pain and disability. Because arthritis prevalence is higher among U.S. military veterans (veterans), and because the veteran population has become more sexually, racially, ethnically, and geographically diverse, updated arthritis prevalence estimates are needed. CDC analyzed pooled 2017-2021 Behavioral Risk Factor Surveillance System data to estimate the prevalence of diagnosed arthritis among veterans and nonveterans, stratified by sex and selected demographic characteristics. Approximately one third of veterans had diagnosed arthritis (unadjusted prevalence = 34.7% [men] and 31.9% [women]). Among men aged 18-44 years, arthritis prevalence among veterans was double that of nonveterans (prevalence ratio [PR] = 2.1; 95% CI = 1.9-2.2), and among men aged 45-64 years, arthritis prevalence among veterans was 30% higher than that among nonveterans (PR = 1.3; 95% CI = 1.3-1.4). Among women aged 18-44 years, arthritis prevalence among veterans was 60% higher than that among nonveterans (PR = 1.6; 95% CI = 1.4-1.7); among women aged 45-64 years, arthritis prevalence among veterans was 20% higher than that among nonveterans (PR = 1.2; 95% CI = 1.1-1.3). Cultivating partnerships with veteran-serving organizations to promote or deliver arthritis-appropriate interventions might be advantageous, especially for states where arthritis prevalence among veterans is highest. The high prevalence of arthritis among female veterans, veterans aged ≥65 years, and veterans with disabilities highlights the importance of ensuring equitable access and inclusion when offering arthritis-appropriate interventions.

Arthritis includes approximately 100 conditions that affect the joints and surrounding tissues. It is a leading cause of activity limitations, disability, and chronic pain, and is associated with dispensed opioid prescriptions, substantially contributing to health care costs. Combined 2019-2021 National Health Interview Survey data were analyzed to update national prevalence estimates of self-reported diagnosed arthritis. An estimated 21.2% (18.7% age-standardized) of U.S. adults aged ≥18 years (53.2 million) had diagnosed arthritis during this time frame. Age-standardized arthritis prevalences were higher among women (20.9%) than men (16.3%), among veterans (24.2%) than nonveterans (18.5%), and among non-Hispanic White (20.1%) than among Hispanic or Latino (14.7%) or non-Hispanic Asian adults (10.3%). Adults aged ≥45 years represent 88.3% of all U.S. adults with arthritis. Unadjusted arthritis prevalence was high among adults with chronic obstructive pulmonary disease (COPD) (57.6%), dementia (55.9%), a disability (54.8%), stroke (52.6%), heart disease (51.5%), diabetes (43.1%), or cancer (43.1%). Approximately one half of adults aged ≥65 years with COPD, dementia, stroke, heart disease, diabetes, or cancer also had a diagnosis of arthritis. These prevalence estimates can be used to guide public health policies and activities to increase equitable access to physical activity opportunities within the built environment and other arthritis-appropriate, evidence-based interventions.

Arthritis affects persons of all ages, including younger adults, adolescents, and children; however, recent arthritis prevalence estimates among children and adolescents aged <18 years are not available. Previous prevalence estimates among U.S. children and adolescents aged <18 years ranged from 21 to 403 per 100,000 population depending upon the case definition used. CDC analyzed aggregated 2017-2021 National Survey of Children's Health data to estimate the national prevalence of parent-reported arthritis diagnosed among children and adolescents aged <18 years. An estimated 220,000 (95% CI = 187,000-260,000) U.S. children and adolescents aged <18 years (305 per 100,000) had diagnosed arthritis. Arthritis prevalence among non-Hispanic Black or African American children and adolescents was twice that of non-Hispanic White children and adolescents. Co-occurring conditions, including depression, anxiety, overweight, physical inactivity, and food insecurity were associated with higher prevalences of arthritis. These findings highlight that children and adolescents should be prioritized for arthritis prevention and treatments by identifying risk factors for arthritis, developing self-management interventions to improve arthritis, physical activity or weight control, and screening and linking to mental health services. Health systems and payors can take steps to ensure equitable access to therapies (e.g., physical therapies and medications).

Caregiving provides numerous benefits to both caregivers and care recipients; however, it can also negatively affect caregivers' mental and physical health (1-4), and caregiving tasks often require physical exertion (1). Approximately 44% of adults with arthritis report limitations attributable to arthritis, including trouble doing daily activities (5). These limitations might affect caregivers' ability to provide care, but little is known about arthritis among caregivers. To assess arthritis among caregivers of a family member or friend, CDC examined data from 17 states that administered both the arthritis and caregiving modules as part of the Behavioral Risk Factor Surveillance System (BRFSS) in either 2017 or 2019. Approximately one in five adults (20.6%) was a caregiver. Prevalence of arthritis was higher among caregivers (35.1%) than noncaregivers (24.5%). Compared with caregivers without arthritis, those with arthritis provided similar types of care and were more likely to have provided care for ≥5 years and for ≥40 hours per week. In addition, higher proportions of caregivers with arthritis reported disabilities compared with those without arthritis, including mobility issues (38.0% versus 7.3%). Arthritis among caregivers might affect their own health as well as the care they can provide. Caregivers can discuss their arthritis and related limitations with a health care professional to identify ways to increase their physical activity and participation in lifestyle management programs.* Such interventions might ease arthritis pain and related limitations and might support them in their ongoing caregiving role. Public health professionals can implement strategies to support caregivers throughout the caregiving process.(†).

Arthritis is associated with joint pain, disability, and physical inactivity, potentially resulting in poor quality of life. The Centers for Disease Control and Prevention analyzed 2019 Behavioral Risk Factor Surveillance System data to estimate state-specific arthritis prevalence and, among adults with arthritis, the prevalence of physical inactivity, fair/poor self-rated health status, and severe joint pain. Among adults with arthritis, age-standardized prevalences of physical inactivity, fair/poor health status, and severe joint pain were high in all states and highest in southeastern states. Increased promotion and use of evidence-based public health interventions for arthritis may improve health-promoting behaviors and health outcomes among adults with arthritis.

Arthritis is a highly prevalent and disabling condition among U.S. adults (1); arthritis-attributable functional limitations and severe joint pain affect many aspects of health and quality of life (2). Self-management education (self-management) and physical activity can reduce pain and improve the health status and quality of life of adults with arthritis; however, in 2014, only 11.4% and 61.0% of arthritis patients reported engaging in each, respectively. To assess self-reported self-management class attendance and health care provider physical activity counseling among adults with doctor-diagnosed arthritis, CDC analyzed 2019 Behavioral Risk Factor Surveillance System (BRFSS) data. In 2019, an age-standardized state median of one in six (16.2%) adults with arthritis reported ever attending a self-management class, and 69.3% reported ever receiving health care provider counselling to be physically active. Prevalences of both differed by state and sociodemographic characteristics; decreased with lower educational attainment, joint pain severity, and urbanicity; and were lower in men than in women. Health care providers can play an important role in promoting self-management class attendance and physical activity by counseling arthritis patients about their benefits and referring patients to evidence-based programs (3).

Primary care providers (PCPs) can offer counseling to adults with arthritis on physical activity, which can reduce pain and improve physical function, mental health, and numerous other health outcomes. We analyzed cross-sectional 2018 DocStyles data for 1,366 PCPs who reported they always or sometimes recommend physical activity to adults with arthritis. Most PCPs sampled (88.2%) recommended walking, swimming, or cycling; 65.5% did not recommend any evidence-based, arthritis-appropriate physical activity programs recognized by the Centers for Disease Control and Prevention. Opportunities exist for public health awareness campaigns to educate PCPs about evidence-based physical activity programs proven to optimize health for adults with arthritis when more than counseling is needed.

The numerous health benefits of physical activity include reduced risk for chronic disease and improved mental health and quality of life (1). Physical activity can improve physical function and reduce pain and fall risk among adults with arthritis, a group of approximately 100 conditions affecting joints and surrounding tissues (most commonly osteoarthritis, fibromyalgia, gout, rheumatoid arthritis, and lupus) (1). Despite these benefits, the 54.6 million U.S. adults currently living with arthritis are generally less active than adults without arthritis, and only 36.2% of adults with arthritis are aerobically active (i.e., meet aerobic physical activity guidelines*) (2). Little is known about which physical activities adults with arthritis engage in. CDC analyzed 2019 Behavioral Risk Factor Surveillance System (BRFSS) data to examine the most common nonwork-related physical activities among adults with arthritis who reported any physical activity during the past month, nationally and by state. In 2019, 67.2% of adults with arthritis reported engaging in physical activity in the past month; among these persons, the most commonly reported activities were walking (70.8%), gardening (13.3%), and weightlifting (7.3%). In 45 U.S. states, at least two thirds of adults with arthritis who engaged in physical activity reported walking. Health care providers can help inactive adults with arthritis become active and, by encouraging physical activity and referring these persons to evidence-based physical activity programs, improve their health and quality of life.

Arthritis has been the most frequently reported main cause of disability among U.S. adults for >15 years (1), was responsible for >$300 billion in arthritis-attributable direct and indirect annual costs in the U.S. during 2013 (2), is linked to disproportionately high levels of anxiety and depression (3), and is projected to increase 49% in prevalence from 2010-2012 to 2040 (4). To update national prevalence estimates for arthritis and arthritis-attributable activity limitation (AAAL) among U.S. adults, CDC analyzed combined National Health Interview Survey (NHIS) data from 2016-2018. An estimated 58.5 million adults aged ≥18 years (23.7%) reported arthritis; 25.7 million (10.4% overall; 43.9% among those with arthritis) reported AAAL. Prevalence of both arthritis and AAAL was highest among adults with physical limitations, few economic opportunities, and poor overall health. Arthritis was reported by more than one half of respondents aged ≥65 years (50.4%), adults who were unable to work or disabled* (52.3%), or adults with fair/poor self-rated health (51.2%), joint symptoms in the past 30 days (52.2%), activities of daily living (ADL)(†) disability (54.8%), or instrumental activities of daily living (IADL)(§) disability (55.9%). More widespread dissemination of existing, evidence-based, community-delivered interventions, along with clinical coordination and attention to social determinants of health (e.g., improved social, economic, and mental health opportunities), can help reduce widespread arthritis prevalence and its adverse effects.

INTRODUCTION: Limited estimates of prescribed opioid use among adults with arthritis exist. All-cause (i.e., for any condition) prescribed opioid dispensed (referred to as opioid prescription in the remainder of this abstract) in the past 12 months among U.S. adults aged ≥18 years (n=35,427) were studied, focusing on adults with arthritis (n=12,875). METHODS: In 2018-2019, estimates were generated using Medical Expenditure Panel Survey data: (1) 2015 prevalence of 1 or more opioid prescriptions to U.S. adults overall and by arthritis status and (2) in 2014-2015, among adults with arthritis, multivariable-adjusted associations between 1 or more opioid prescriptions and sociodemographic characteristics, health status, and healthcare utilization characteristics. RESULTS: In 2015, the age-standardized prevalence of 1 or more opioid prescriptions among adults with arthritis (29.6%) was almost double of that for all adults (15.4%). Adults with arthritis represented more than half of all adults (55.3%) with at least 1 opioid prescription; among those with 1 or more prescriptions, 43.2% adults had 4 or more prescriptions. The strongest multivariable-adjusted associations with 1 or more opioid prescriptions were ambulatory care visits (1-4: prevalence ratios=1.9-2.0, 5-8: prevalence ratios=2.5-2.7, 9 or more: prevalence ratios=3.4-3.7) and emergency room visits (1: prevalence ratios=1.6, 2-3: prevalence ratios=1.9-2.0, 4 or more: prevalence ratios=2.4); Ref for both: no visits. CONCLUSIONS: Adults with arthritis are a high-need target group for improving pain management, representing more than half of all U.S. adults with 1 or more opioid prescriptions. The association with ambulatory care visits suggests that providers have routine opportunities to discuss comprehensive and integrative pain management strategies, including low-cost evidence-based self-management approaches (e.g., physical activity, self-management education programs, cognitive behavioral therapy). Those with multiple opioid prescriptions may need extra support if transitioning to nonopioid and nonpharmacologic pain management strategies.

OBJECTIVES: To examine the relationship between depressive symptoms, arthritis, and employment participation. To determine if this relationship differs across young, middle, and older working-age adults with arthritis. METHODS: Data from the US National Health Interview Survey, years 2013-2017, were analyzed. Analyses were restricted to those with doctor-diagnosed arthritis of working age (18-64 years) with complete data on depressive symptoms (n=11,380). Covariates were sociodemographic, health, and health system use variables. Employment prevalence was compared by self-reported depressive symptoms. We estimated percentages, univariable, and multivariable logistic regression models to examine the relationship between depression and employment among young (18-34 years), middle (35-54 years), and older adults (55-64 years). RESULTS: Among all working-age US adults with arthritis, prevalence of depressive symptoms was 13%. Those reporting depressive symptoms had higher prevalence of fair/poor health (60%) and arthritis-attributable activity limitations (70%) compared with those not reporting depression (23% and 39%, respectively). Respondents with depressive symptoms reported significantly lower employment prevalence (30%) when compared with those not reporting depressive symptoms (66%) and lower multivariable-adjusted association with employment (PR=0.88, 95% CI [confidence interval] 0.83-0.93). Middle-age adults reporting depression were significantly less likely to be employed compared with their counterparts without depression (PR=0.83, 95% CI 0.77-0.90); similar but borderline statistically significant relationships were observed for both younger (PR=0.86, 95% CI 0.74-0.99) and older adults (PR=0.94. 95% CI 0.86-1.03). CONCLUSION: For adults with arthritis, depressive symptoms are associated with not participating in employment. Strategies to reduce arthritis-related work disability may be more effective if they simultaneously address mental health.

An estimated 54.4 million (approximately one in four) U.S. adults have doctor-diagnosed arthritis (arthritis) (1). Severe joint pain and physical inactivity are common among adults with arthritis and are linked to adverse mental and physical health effects and limitations (2,3). CDC analyzed 2017 Behavioral Risk Factor Surveillance System (BRFSS) data to estimate current state-specific prevalence of arthritis and, among adults with arthritis, the prevalences of severe joint pain and physical inactivity. In 2017, the median age-standardized state prevalence of arthritis among adults aged >/=18 years was 22.8% (range = 15.7% [District of Columbia] to 34.6% [West Virginia]) and was generally highest in Appalachia and Lower Mississippi Valley regions.* Among adults with arthritis, age-standardized, state-specific prevalences of both severe joint pain (median = 30.3%; range = 20.8% [Colorado] to 45.2% [Mississippi]) and physical inactivity (median = 33.7%; range = 23.2% [Colorado] to 44.4% [Kentucky]) were highest in southeastern states. Physical inactivity prevalence among those with severe joint pain (47.0%) was higher than that among those with moderate (31.8%) or no/mild joint pain (22.6%). Self-management strategies such as maintaining a healthy weight or being physically active can reduce arthritis pain and prevent or delay arthritis-related disability. Evidence-based physical activity and self-management education programs are available that can improve quality of life among adults with arthritis.

An estimated 54.4 million (22.7%) U.S. adults have doctor-diagnosed arthritis (1). A report in 2012 found that, among adults aged >/=45 years with arthritis, approximately one third reported having anxiety or depression, with anxiety more common than depression (2). Studies examining mental health conditions in adults with arthritis have focused largely on depression, arthritis subtypes, and middle-aged and older adults, or have not been nationally representative (3). To address these knowledge gaps, CDC analyzed 2015-2017 National Health Interview Survey (NHIS) data* to estimate the national prevalence of clinically relevant symptoms of anxiety and depression among adults aged >/=18 years with arthritis. Among adults with arthritis, age-standardized prevalences of symptoms of anxiety and depression were 22.5% and 12.1%, respectively, compared with 10.7% and 4.7% among adults without arthritis. Successful treatment approaches to address anxiety and depression among adults with arthritis are multifaceted and include screenings, referrals to mental health professionals, and evidence-based strategies such as regular physical activity and participation in self-management education to improve mental health.

In the article titled "Updated Estimates Suggest a Much Higher Prevalence of Arthritis in United States Adults than Previous Ones", Jafarzadeh and Felson present an alternative estimate of arthritis prevalence. (1) Specifically, using a new case definition for arthritis and applying Bayesian methods to correct for misclassification, Jafarzadeh and Felson analyzed National Health Interview Survey (NHIS) data and estimated that in 2015, 91.2 million US adults had arthritis. In contrast, CDC had estimated from the 2013-2015 NHIS that 54.4 million US adults had doctor-diagnosed arthritis. (2) In this letter, we make two observations about their methods and discuss implications for public health surveillance of arthritis. This article is protected by copyright. All rights reserved.

In the United States, 54.4 million adults report having doctor-diagnosed arthritis (1). Among adults with arthritis, 32.7% and 38.1% also have overweight and obesity, respectively (1), with obesity being more prevalent among persons with arthritis than among those who do not have arthritis (2). Furthermore, severe joint pain among adults with arthritis in 2014 was reported by 23.5% of adults with overweight and 31.7% of adults with obesity (3). The American College of Rheumatology recommends weight loss for adults with hip or knee osteoarthritis and overweight or obesity,* which can improve function and mobility while reducing pain and disability (4,5). The Healthy People 2020 target for health care provider (hereafter provider) counseling for weight loss among persons with arthritis and overweight or obesity is 45.3%.(dagger) Adults with overweight or obesity who receive weight-loss counseling from a provider are approximately four times more likely to attempt to lose weight than are those who do not receive counseling (6). To estimate changes in the prevalence of provider counseling for weight loss reported by adults with arthritis and overweight or obesity, CDC analyzed National Health Interview Survey (NHIS) data.( section sign) Overall, age-standardized estimates of provider counseling for weight loss increased by 10.4 percentage points from 2002 (35.1%; 95% confidence interval [CI] = 33.0-37.3) to 2014 (45.5%; 95% CI = 42.9-48.1) (p<0.001). Providing comprehensive behavioral counseling (including nutrition, physical activity, and self-management education) and encouraging evidence-based weight-loss program participation can result in enhanced health benefits for this population.

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.

Rural populations in the United States have well documented health disparities, including higher prevalences of chronic health conditions (1,2). Doctor-diagnosed arthritis is one of the most prevalent health conditions (22.7%) in the United States, affecting approximately 54.4 million adults (3). The impact of arthritis is considerable: an estimated 23.7 million adults have arthritis-attributable activity limitation (AAAL). The age-standardized prevalence of AAAL increased nearly 20% from 2002 to 2015 (3). Arthritis prevalence varies widely by state (range = 19%-36%) and county (range = 16%-39%) (4). Despite what is known about arthritis prevalence at the national, state, and county levels and the substantial impact of arthritis, little is known about the prevalence of arthritis and AAAL across urban-rural areas overall and among selected subgroups. To estimate the prevalence of arthritis and AAAL by urban-rural categories CDC analyzed data from the 2015 Behavioral Risk Factor Surveillance System (BRFSS). The unadjusted prevalence of arthritis in the most rural areas was 31.8% (95% confidence intervals [CI] = 31.0%-32.5%) and in the most urban, was 20.5% (95% CI = 20.1%-21.0%). The unadjusted AAAL prevalence among adults with arthritis was 55.3% in the most rural areas and 49.7% in the most urban. Approximately 1 in 3 adults in the most rural areas have arthritis and over half of these adults have AAAL. Wider use of evidence-based interventions including physical activity and self-management education in rural areas might help reduce the impact of arthritis and AAAL.

OBJECTIVES: To examine the association between arthritis diagnosis and educational and employment participation among young adults, and to determine whether findings differ by self-rated health and age. METHODS: Data from the National Health Interview Survey, years 2009 to 2015, were combined and analyzed. Our sample was restricted to those aged 18-29 years either diagnosed with arthritis (n = 1,393) or not (n = 40,537). Prevalence and correlates of employment and educational participation were compared by arthritis status. Demographic characteristics, social role participation restrictions, health factors, and health system use variables were included as covariates. Models were stratified for age (18-23 versus 24-29) and self-rated health. Weighted proportions, univariate, and multivariate associations were calculated to examine the association between arthritis and educational and employment participation. RESULTS: Arthritis respondents were more likely to be female, married, report more social participation restrictions, fair/poor health, and functional limitations than those without arthritis. In multivariate models, arthritis was significantly associated with lower education (PR = 0.75; 95%CI 0.57-0.98) and higher employment participation (PR = 1.07; 95%CI 1.03-1.13). Additional stratified analyses indicated that the association between arthritis diagnosis and greater employment participation was uncovered for those aged 18-23 years and reporting higher self-rated health. CONCLUSION: Young adults with arthritis may be transitioning into employment at an earlier age than their non-arthritis peers. To inform the design of interventions that promote employment participation, there is a need for future research to better understand the educational and employment experiences of young adults with arthritis.

OBJECTIVE: 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 age ≥ 18 years. METHODS: Respondents with arthritis were those who reported ever being diagnosed with arthritis by a doctor or health care provider. We analyzed 2014 National Health Interview Survey (NHIS) data to estimate: 1) percentage (unadjusted and age-standardized) who ever attended a SME program overall and for selected subgroups, 2) representativeness of SME participants relative to all adults with arthritis, and 3) trends in SME course participation. RESULTS: In 2014, 1 in 9 US adults with arthritis (percentage=11.3; 95% CI=10.4-12.3); age-standardized percentage=11.4; [95% CI=10.0-12.9]) had ever participated in a SME program. SME participation (age-standardized) was highest among those with ≥ 8 health care provider visits in the past 12 months (16.0%; 95% CI=13.1 - 19.4). Since 2002, the number of adults with arthritis who have ever participated in SME has increased by 1.7 million but the percentage has remained constant. CONCLUSION: Despite its many benefits, SME participation among US adults with arthritis remains persistently low. By recommending that their patients attend SME programs, health care providers can increase the likelihood that their patients experience SME program benefits. This article is protected by copyright.

OBJECTIVE: To update projections of arthritis prevalence and arthritis-attributable activity limitations (AAAL) for adults using a newer baseline. METHODS: Baseline prevalence data were obtained from the 2010-2012 National Health Interview Survey. Arthritis was defined as a "yes" response to "Have you ever been told by a doctor or other health professional that you have some form of arthritis, rheumatoid arthritis, gout, lupus or fibromyalgia?" AAAL was defined as a "yes" response to "Are you limited in any way in any of your usual activities because of arthritis or joint symptoms." The baseline prevalence of arthritis and AAAL was stratified by age (18-34, 35-44, 45-54, 55-64, 65-74, 75-84, and 85+) and sex and statistically weighted to account for the complex survey design. Projected arthritis and AAAL prevalence was calculated by multiplying the US Census projected age and sex population estimates for 2015-2040 (in 5-year intervals) by the baseline estimates, and summed to provide the total prevalence estimates for each year. RESULTS: In 2010-2012 there were 52.5 million (22.7%) US adults with doctor-diagnosed arthritis, of whom 22.7 million (9.8% of all adults) had AAAL. By 2040 the prevalence of doctor-diagnosed arthritis is projected to increase 49% to 78.4 million (25.9% of adults). The number of adults with AAAL will also increase 52% to 34.6 million (11.4% of all adults). CONCLUSION: Updated projections suggest arthritis and AAAL will remain large and growing problems for clinical and public health systems, which must plan and create policies and resources to address these future needs.
