The CATCH research study follows people who have a type of arthritis called Rheumatoid Arthritis (RA), which:
- affects about 1% of the population
- can affect some 68 joints in your body through inflammation
- can begin very suddenly and involve many joints or slowly in just a few joints (which can make it very hard to detect – a person might just blame an activity for the symptoms they are feeling)
- is an autoimmune disease where a person’s immune system attacks their own tissues
- doesn’t have a cure, but there are a number of ways to manage living with it.
Below is information about RA and information and links to credible arthritis organizations.
Rheumatoid Arthritis Symptoms
Symptoms of RA can affect different people very differently. In general, symptoms include:
- joint tenderness, warmth, and swelling. Often both sides of your body are affected at the same time, which is called a “symmetrical pattern” of inflammation. For example, if one wrist or knee is affected, the other one is also. This is different from osteoarthritis, where it is possible for only one knee to be affected and which usually involves the small joints of the hands and feet
- pain and stiffness that lasts for more than 1 hour in the morning or after a long rest
- joint inflammation in the wrist and finger joints closest to the hand and small joints of the feet (although joints of the neck, shoulders, elbows, hips, knees, and ankles can be affected as well)
- when pain, swelling, and soreness increase, it is called a “flare”
- fatigue (i.e. being very tired), rarely fevers and a general feeling of not being well
To be diagnosed with RA, these symptoms must last for more than 6 weeks. The symptoms of RA are often seen in other parts of the body besides the joints.
Rheumatoid Arthritis Risk Factors
The exact cause of RA is unknown, however recent research points to many factors causing RA. These include genetic factors (i.e. these are inherited from your parents), environmental factors and others. What we know about these factors is outlined below.
Genetic Factors. Certain genes that play a role in the immune system are linked with a person’s chances of developing RA. However, many people with RA do not have these specific genes while other people have these genes but never develop RA. This suggests that while a person’s genetic makeup is an important part of the story, it is not the sole reason for why a person develops RA.
Environmental Factors. Many researchers believe that something in a person’s environment triggers RA in people who have the genetic makeup that makes them susceptible to RA. It is thought that this environmental factor could be an infectious agent like a virus or bacterium but none have been identified yet. This does not mean that RA is contagious – we know that it cannot be transmitted from person to person. Other environmental factors thought to play a role in the development of RA include smoking and exposure to excessive pollution (e.g. from traffic). Research has shown that being exposed to cigarette smoke is strongly linked with the development of RA and the severity of RA that is developed.
Other related factors. Some scientists believe that certain hormonal factors may be involved in the development of RA. It is thought that these hormonal deficiencies/changes may trigger RA in a genetically susceptible person who has been exposed to an environmental trigger.
Dietary factors. The role of diet with respect to RA needs further research.
Sex. In general, RA occurs much more frequently in women than in men.
