Arthritis-Related Statistics

Lifetime risk of symptomatic osteoarthritis (OA)

Note: There are different data sources for some of the arthritis related statistics; therefore, case definitions and terminology will also vary. Read more.

  • Nearly 1 in 2 people may develop symptomatic knee OA by age 85 years.1
  • Two in three people who are obese may develop symptomatic knee OA in their lifetime.1
  • One in 4 people may develop painful hip arthritis by age 85 years.2

 

Prevalence of Arthritis

Note: There are different data sources for some of the arthritis related statistics; therefore, case definitions and terminology will also vary. Read more.

  • From 2010- 2012, an estimated 52.5 million US adults (22.7%) annually were ever told by a doctor that they have some form of arthritis, rheumatoid arthritis, gout, lupus, or fibromyalgia.3
  • An estimated 49.7% of adults 65 years or older reported doctor-diagnosed arthritis from 2010-2012.3
  • An estimated 62% of adults with arthritis are <65 years old.
  • By 2040, an estimated 78 million Americans ages 18 years or older are projected to have doctor-diagnosed arthritis.4
  • An estimated 294,000 children under age 18 have some form of arthritis or rheumatic condition; this represents approximately 1 in every 250 children in the United States.5

Prevalence of Specific Types of Arthritis

Note: There are different data sources for some of the arthritis related statistics; therefore, case definitions and terminology will also vary. Read more.

Overweight/Obesity and Arthritis (adults ages ≥18 years)

Note: There are different data sources for some of the arthritis related statistics; therefore, case definitions and terminology will also vary. Read more.

  • Adults who are overweight or obese report doctor-diagnosed arthritis more often than adults with a lower body mass index (BMI).
    • Almost 16% of under/normal weight adults report doctor-diagnosed arthritis.3
    • Almost 23% of overweight and 31% of obese Americans report doctor-diagnosed arthritis.3
  • Weight loss of as little as 11 pounds reduces the risk of developing knee osteoarthritis among women by half.9

Physical Activity and Arthritis

Note: There are different data sources for some of the arthritis related statistics; therefore, case definitions and terminology will also vary. Read more.

  • Among older adults with knee osteoarthritis, engaging in moderate physical activity at least 3 times per week can reduce the risk of arthritis-related disability by 47%.10

Disability/Limitations and Arthritis

Note: There are different data sources for some of the arthritis related statistics; therefore, case definitions and terminology will also vary. Read more.

Most Common Cause of Disability

  • Arthritis and other rheumatic conditions are the most common cause of disability among US adults, and were the most common cause of disability among US adults for the past 15 years.12 

Activity Limitation

  • Among all civilian, non-institutionalized U.S. adults 9.8% (22.7 million) had both doctor-diagnosed arthritis and arthritis attributable activity limitations.3
  • Around 43% of adults with doctor-diagnosed arthritis also had arthritis-attributable activity limitations from 2010-2012.3
  • Among adults with doctor-diagnosed arthritis, many report significant functional limitations such as:
    • Walking 1/4 mile— About 1 in 6.
    • Grasping— About 1 in 22.
    • Climbing stairs— About 1 in 9. 

 

Work Limitation

  • Approximately 1 in 3 people with doctor-diagnosed arthritis (31%) between the ages of 18 and 64 report arthritis-attributable work limitation.12
  • Among all civilian, non-institutionalized U.S. adults ages 18-64, 5% (8.2 million) report arthritis-attributable work limitations.14 [This translates into 1 in 3 (31%) of adults with doctor-diagnosed arthritis in that age group12.]  
  • State-specific prevalence estimates of arthritis-attributable work limitation show a high impact of doctor-diagnosed arthritis on working-age (18-64 years) adults in all U.S. states, ranging from a low of 3.4% to a high of 15% of adults in this age group.13

Health Related Quality of Life (HRQOL) and Arthritis

Note: There are different data sources for some of the arthritis related statistics; therefore, case definitions and terminology will also vary. Read more.

  • People with doctor-diagnosed arthritis have significantly worse HRQOL than those without arthritis. Adults with arthritis report two to four times as many unhealthy days in the past month than those without arthritis.16
  • Physical health is affected most by arthritis (6.6 unhealthy days per month on average), but also mental health (5.4 unhealthy days per month on average).14

 

Arthritis Healthcare Utilization

Note: There are different data sources for some of the arthritis related statistics; therefore, case definitions and terminology will also vary. Read more.

Hospitalizations

  • In 2011 there were an estimated 6.7 million hospitalizations with a principal diagnosis of arthritis and other rheumatic conditions.15
     

Ambulatory Care

In 2010 there were more than 100 million ambulatory care visits with a primary diagnosis of arthritis or other rheumatic conditions, or nearly 10% of all ambulatory care visits that year. Between 2%t to 6% of all ambulatory care visits listed arthritis as the primary diagnosis.15

Arthritis-Related Mortality

Note: There are different data sources for some of the arthritis related statistics; therefore, case definitions and terminology will also vary. Read more.

  • From 1979–1998, the annual number of arthritis and other rheumatic conditions (AORC) deaths rose from 5,537 to 9,367.16
  • Three categories of AORC account for almost 80% of deaths: diffuse connective tissue diseases, especially lupus (34%), other specified rheumatic conditions (23%), and rheumatoid arthritis (22%).16
  • In 1979, the crude death rate from AORC was 2.46 per 100,000 persons. In 1998, it was 3.48 per 100,000 persons; rates age-standardized to the year 2000 population were 2.75 and 3.51, respectively.16

Mental/Emotional Health and Arthritis

Note: There are different data sources for some of the arthritis related statistics; therefore, case definitions and terminology will also vary. Read more.

  • Arthritis is strongly associated with major depression (attributable risk of 18.1%), probably through its role in creating functional limitation.17
  • Almost 7% of adults with arthritis report severe psychological distress.18

Total Joint Replacements in Arthritis

Note: There are different data sources for some of the arthritis related statistics; therefore, case definitions and terminology will also vary. Read more.

  • In 2011, there were 757,000 total knee replacement procedures performed, with osteoarthritis accounting for 95%.15
  • In 2011, there were 512,000 total hip replacement procedures (OA accounted for 80%).15
