The word arthritis actually means joint inflammation, but the term has acquired a wider meaning. In public health, arthritis is used as a shorthand term for arthritis and other rheumatic conditions—a label for the more than 100 rheumatic diseases and conditions that affect joints, the tissues which surround joints and other connective tissue. The pattern, severity, and location of symptoms can vary depending on the specific form of the disease. Typically, rheumatic conditions are characterized by pain and stiffness in and around one or more joints. The symptoms can develop gradually or suddenly. Certain rheumatic conditions can also involve the immune system and various internal organs of the body.
A brief overview of the most common forms of arthritis are discussed in the types section. For a more detailed discussion of each of these conditions follow the links provided for you. The Resources and Links section of our Web site can guide you to further information on many topics related to rheumatic diseases.
Certain factors are associated with a greater risk of arthritis. Some of these risk factors are modifiable while others are not.
Elevated uric acid levels cause gout, and specific infections can cause certain forms of arthritis. The causes of many of the other forms of arthritis are unknown. Scientists are studying the role of factors such as genetics, lifestyle, and environment in the various types of arthritis.
The most common form of arthritis in the Unites States is osteoarthritis followed by gout, fibromyalgia, and rheumatoid arthritis.
The pattern and location of symptoms can vary depending on the type of arthritis. Generally, people with arthritis feel pain and stiffness in and around one or more joints. The onset of arthritis symptoms can develop gradually or suddenly. Arthritis is most often a chronic disease, so symptoms may come and go, or persist over time.
If you have pain, stiffness, or swelling in or around one or more of your joints, talk to your doctor. It is important to keep in mind that there are many forms of arthritis, and a specific diagnosis of the type you have may help to direct the proper treatment. Although there is no cure for most types of arthritis, early diagnosis and appropriate management are important, especially for inflammatory types of arthritis. For example, early use of disease-modifying drugs can affect the course of rheumatoid arthritis. An early diagnosis and appropriate treatment can make a difference in pain and joint damage. The earlier you understand your arthritis, the earlier you can start managing your disease and making healthy lifestyle changes to help your arthritis.
Depending on the form of arthritis, there are steps that can be taken to reduce your risk of arthritis. Maintaining an appropriate body weight has been shown to decrease the risk of developing osteoarthritis and gout. Protecting your joints from injuries or overuse can reduce the risk of osteoarthritis.
Diagnosing arthritis often requires a detailed medical history of current and past symptoms, physical examination, x-rays, and blood work. It is possible to have more than one form of arthritis at the same time.
The focus of treatment for arthritis is to control pain, minimize joint damage, and improve or maintain function and quality of life. According to the American College of Rheumatology, the treatment of arthritis might involve the following:
In conjunction with medical treatment, self-management of arthritis symptoms is very important as well. The Arthritis Foundation Self Help Program and the Chronic Disease Self-Management Program, both developed by Dr. Kate Lorig of Stanford University, are effective self-management education programs. The program helps people develop the skills needed to manage their arthritis on a day to day basis and gain the confidence to carry it out.
For management of specific types of arthritis, refer to the types section.
Both medical treatment and self-management strategies are very important. The Arthritis Foundation Self Help Program and the Chronic Disease Self-Management Program, both developed by Dr. Kate Lorig of Stanford University, are effective self-management education programs. These programs help people learn the techniques needed to manage their arthritis on a day to day basis and gain the confidence to carry it out.
The CDC recommends the following:
Early diagnosis and appropriate management of arthritis, including self-management activities, can help people with arthritis decrease pain, improve function, stay productive, and lower health care costs. Key self-management activities include the following:
Learn Arthritis Management Strategies—Learning techniques to reduce pain and limitations can be beneficial to people with arthritis. Self-management education, such as the Arthritis Foundation Self Help Program (AFSHP), or the Chronic Disease Self Management Program (CDSMP) help you learn the strategies and develop the confidence to manage your arthritis on a day to day basis. For example, AFSHP has been shown to reduce pain even 4 years after participating in the program.
Be Active—Research has shown that physical activity decreases pain, improves function, and delays disability. Make sure you get at least 30 minutes of moderate physical activity 3 days a week. You can get activity in 10-minute intervals.
Watch Your Weight—The prevalence of arthritis increases with increasing weight. Research suggests that maintaining a healthy weight reduces the risk of developing arthritis and may decrease disease progression. A loss of just 11 pounds can decrease the occurrence (incidence) of new knee osteoarthritis.
See Your Doctor—Although there is no cure for most types of arthritis, early diagnosis and appropriate management are important, especially for inflammatory types of arthritis. For example, early use of disease-modifying drugs can affect the course of rheumatoid arthritis. If you have symptoms of arthritis, see your doctor and begin appropriate management of your condition.
Protect Your Joints—Joint injury can lead to osteoarthritis. People who experience sports or occupational injuries or have jobs with repetitive motions like repeated knee bending have more osteoarthritis. Avoid joint injury to reduce your risk of developing osteoarthritis.
Currently, an estimated 46 million Americans reported that their doctor told them they had arthritis. As our nation’s population ages, the prevalence is expected to increase.
A new CDC study estimates that 294,000 U.S. children under age 18 (or 1 in 250 children) have been diagnosed with arthritis or another rheumatologic condition. (Type data table and state table.) Prior estimates ranged from 80,000 to 290,000, depending on the definition of arthritis, age range and methods used to find cases. However, many of these prior estimates were based on extrapolations from small studies done in small geographic areas which could have led lead to chance variation in estimates. More info.

There are 12 states that have arthritis programs funded by the CDC. Eight additional states have received funds to help make arthritis appropriate interventions available. Link to the map on the Web site that has the states highlighted.
Recent studies have shown that moderate physical activity 3 or more days a week can help to relieve arthritis pain and stiffness and give you more energy. Regular physical activity can also lift your mood and make you feel more positive.
An activity that produces a slight increase in heart rate or breathing is considered moderate physical activity. Low-impact activities performed at a moderate pace work best for people with arthritis. These include walking, swimming, and riding a bicycle. Everyday activities such as dancing, gardening, and washing the car can be good if done at a moderate pace that produces slight breathing and heart rate changes.
If you are having an acute flare-up of your inflammatory arthritis, it may be better to restrict your exercise to simple range of motion (carefully moving the joint as far as it can go) during the flare-up.
Weight control is essential; research suggests that maintaining a healthy weight reduces the risk of developing osteoarthritis and may decrease disease progression. A loss of just 11 pounds can decrease the occurrence (incidence) of new knee osteoarthritis.
