An increased body mass index (BMI) is a significant risk factor for osteoarthritis development. However, a recent study indicates that being overweight increases the risk of developing inflammatory joint diseases like rheumatoid arthritis.
The study included around 362,000 people who were members of the UK Biobank, a sizable biological database, and was published online by the journal Arthritis and Rheumatology on May 23, 2023. In order to determine a participant's risk of developing any of five joint conditions—rheumatoid arthritis, osteoarthritis, psoriatic arthritis, gout, and inflammatory spondylitis, a form of spinal arthritis—researchers looked at the relationship between the participant's BMI and these conditions. Apart from osteoarthritis, inflammation is the primary cause of most other joint illnesses.
Compared to those in the normal BMI range, participants with higher BMIs (substantially greater than the "normal" BMI range of 18.5 to 24.9) had higher incidences of psoriatic arthritis (80%), gout (73%), inflammatory spondylitis (34%), and rheumatoid arthritis (52%). The authors of the study found that maintaining a healthy weight can help lower the chance of acquiring a joint illness.
