A new study shows the prevalence of gout in the U.S. has risen over the last twenty years and now affects 8.3 million (4%) Americans. Prevalence of increased uric acid levels (hyperuricemia) also rose, affecting 43.3 million (21%) adults in the U.S. Greater frequency of obesity and hypertension may be associated with the jump in prevalence rates according to the findings now available in Arthritis & Rheumatism, a journal published by Wiley-Blackwell on behalf of the American College of Rheumatology (ACR).
Gout, an inflammatory arthritis triggered by crystallization of uric acid within the joints, causes severe pain and swelling. Medical evidence suggests that gout is strongly associated with metabolic syndrome—a group of health conditions characterized by central obesity, insulin resistance, high blood pressure and blood lipid issues—and may lead to heart attack, diabetes and premature death. Prior research found that gout incidence in the U.S. more than doubled from the 1960s to 1990s.
"Our study aim was to determine if the prevalence of gout and hyperuricemia among U.S. adults has continued to climb in the new millennium," said Dr. Hyon Choi, Professor of Medicine in the Section of Rheumatology and the Clinical Epidemiology Unit at Boston University School of Medicine in Massachusetts and senior investigator of the present study.
Researchers analyzed data from the latest U.S. National Health and Nutrition Examination Survey (NHANES) which was conducted in 2007 and 2008, comparing the data with those from previous NHANES surveys (1988-1994). There were 5,707 participants who completed the most recent NHANES survey which included questions regarding history of gout diagnosed by a healthcare professional. Researchers defined hyperuricemia as serum urate level greater than 7.0 mg/dL in men and 5.7 mg/dL in women.
Results from the nationally-representative sample of adult Americans suggest gout and hyperuricemia remain prevalent in the U.S. and compared to earlier NHANES data was 1% and 3% higher, respectively. After adjusting for obesity or hypertension, the differences in prevalence rates were substantially lessened. Further analysis revealed that gout prevalence was higher in men (6%) compared to women (2%); hyperuricemia occurred in 21.2% of men and 21.6% of women.
Dr. Choi concluded, "We found that the prevalences of gout and hyperuricemia continue to be substantial in the U.S. adult population. Improvements in managing modifiable risk factors, such as obesity and hypertension, could help prevent further escalation of gout and hyperuricemia among Americans."

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
