This study, conducted by Professor Pan An's team from the School of Public Health, Tongji Medical College, Huazhong University of Science and Technology, and experts from many countries, is based on data from four cohorts and more than 840,000 people in four countries: China, the United Kingdom, the United States, and Spain. It systematically verifies the refined diagnostic framework proposed by the Lancet Committee, marking the need for the global obesity diagnosis and treatment system to enter a new stage with "accurate assessment" and "health function" as the core.
