Osteoarthritis Affecting More African Americans
Osteoarthritis, the most common type of arthritis that affects multiple joints, is becoming more common among African Americans, according to new research published in Arthritis & Rheumatism, a peer-reviewed journal of the American College of Rheumatology (ACR).
This study was conducted by part of the Johnston County Osteoarthritis Project, Dr. Amanda Nelson from the University of North Carolina at the Chapel Hill-UNC Rheumatology/Thurston Arthritis Research Center and colleagues.
African Americans have a higher prevalence of multiple, large-joint osteoarthritis (OA), which may not be recognized based on the current definition of "generalized OA."
For the study radiographic data was analyzed for the hands, knee, hips and spine in African American and Caucasian men and women aged 45 years and older. Researchers obtained age, gender, race and body mass index (BMI) data by using questionnaires and clinical examination. The average age of the study participants was 65 years or older, with an average BMI classed as 'obese'. A third of the participants were male and two thirds were Caucasian.
According to the evaluation, African Americans are at greater risk to develop OA in the knew joint compared to Caucasians but are less likely to be affected by OA in the hand, Medical News Today reports.
