Aging-related joint disorder increasingly affects people under 40, study finds

Cases of gout are rising in younger individuals, according to a global study.The condition, which is a type of inflammatory arthritis, steadily increased in people aged 15 to 39 between 1990 and 2021, researchers in China announced.Although rates vary widely between countries, the total number of young people with the condition is expected to continue rising through 2035.The study, published in the journal Joint Bone Spine, investigated 2021 data from the Global Burden of Disease (GBD), spanning 204 countries within the 30-year timeframe.The data measured gout prevalence, incidence and years lived with disability, tracking global trends over time.The results showed a global increase across all three outcomes.Prevalence and disability years increased by 66%, and incidence rose by 62%.In 2021, 15- to 39-year-olds accounted for nearly 14% of new gout cases globally, the study found.Men from 35 to 39 years old and people in high-income regions had the highest burden, but high-income North America topped the list for highest rates.Men were also found to have lived more years with gout due to high BMI, while women tended to have the condition as a link to kidney dysfunction, the study noted.The total number of cases is expected to increase globally due to population growth, but the study projected that rates per population would decrease.The researchers noted that data quality, especially in low-income settings, could have posed a limitation to the broad GBD data.Gout is a common form of arthritis involving sudden and severe attacks of pain, swelling, redness and tenderness in the joints, according to Mayo Clinic.
It most often occurs in the big toe.The condition occurs when urate crystals accumulate in the joint.These form when there are high levels of uric acid in the blood, which the body produces when it breaks down a natural substance called purines.A gout flare-up can happen at any time, often at night, causing the affected joint to feel hot, swollen, tender ...
