Obesity: A Major Risk Factor for Knee Osteoarthritis

Recent research conducted by the University of Sydney highlights the significant role of obesity in the development of knee osteoarthritis. The study confirms that obesity, prior knee injuries, and certain occupational factors such as shift work and heavy lifting substantially increase the risk of developing this degenerative joint disease. Additionally, lifestyle choices appear to influence the likelihood of developing knee osteoarthritis. The study suggests that adopting a healthy diet—such as the Mediterranean diet, incorporating green tea, and consuming dark bread—may help reduce the risk.

This comprehensive analysis reviewed data from 131 studies spanning over three decades, involving participants aged 20 to 80. The researchers identified more than 150 risk factors associated with knee osteoarthritis. They emphasized that lifestyle modifications, including weight loss and better dietary habits, could significantly enhance health outcomes and decrease disease prevalence.

Knee osteoarthritis affects over 500 million people globally and is a leading cause of disability. The research found that women are twice as likely to develop the condition compared to men, and that advanced age only slightly increases the risk. Dr. Vicky Duong, the study’s lead author, noted that eliminating obesity and preventing knee injuries could potentially reduce knee osteoarthritis cases by up to 14%.

The authors call for policy reforms to address occupational risks and promote preventive measures such as injury prevention programs and healthy lifestyle initiatives. Increased awareness and proactive healthcare strategies are vital to combat this widespread condition.
