摘要With rapid urbanization and economic development,obesity has emerged as a major public health concern in China. According to the latest Global Burden of Diseases study,there were 402 million overweight and obese Chinese adults in 2021 and this number is projected to further increase to 627 million by 2050[1]. Obesity is closely associated with an elevated risk of type 2 diabetes,cardiovascular and cerebrovascular diseases,depression,and certain cancers[2,3]. In addition to being a risk factor,excess adiposity can directly damage end-organs and affect the ability to conduct daily activities[4]. In this comment,we aim to provide an overview of the epidemiology of obesity among Chinese adults based on the China Chronic Disease and Risk Factor Surveillance (CCDRFS) and summarize the related determinants and health policies against obesity.
