Osteoarthritis: One billion people will suffer from this disease by 2050; deets inside

The most common type of arthritis, impacting millions of individuals globally, is Osteoarthritis. It happens as the protective cartilage that cushions the ends of the bones deteriorates over time. This disease is increasing in humans and research showed that nearly one billion people will suffer from this disease by 2050. The study discovered that osteoarthritis cases have increased quickly over the last three decades due to three major factors: ageing, population growth, and obesity.

Study suggests the spread of osteoarthritis

According to a study, about one billion people worldwide will have osteoarthritis by 2050, with 15% of those aged 30 and older presently suffering from the most common type of arthritis. The study, which was just published in The Lancet Rheumatology journal, examined 30 years of osteoarthritis data from 1990 to 2020 from more than 200 nations. The team, coordinated by researchers at the Institute for Health Metrics and Evaluation (IHME) in the United States, discovered that instances grew quickly over the last three decades due to three major factors: ageing, population expansion, and obesity.

The term "arthritis" literally means "joint inflammation." The most common type of arthritis, impacting millions of individuals globally, is osteoarthritis. It happens as the protective cartilage that cushions the ends of the bones deteriorates over time.

Women have more osteoarthritis than men

Osteoarthritis affected 256 million individuals in 1990. By 2020, this figure had risen to 595 million people, a 132% increase from 1990. According to the researchers, by 2050, this figure is expected to surpass one billion. The most common sites for osteoarthritis are the knees and hips. This illness is predicted to affect more women than men in the future. In 2020, women accounted for 61% of osteoarthritis cases, while men accounted for 39%. According to them, there are several probable explanations for this gender disparity. Study shows that obesity, or having a high body mass index (BMI), is a risk factor for osteoarthritis.

"The reasons for gender differences in osteoarthritis prevalence are being investigated, but researchers believe that genetics, hormonal factors, and anatomical differences all play a role," said Jacek Kopek, senior author and professor at the University of British Columbia in Canada.
