亚洲人BMI多少算肥胖？国际权威期刊呼吁重新定义标准！

Core Viewpoint - A new study published in the Annals of Internal Medicine emphasizes the need for a revised Body Mass Index (BMI) standard for Asian populations due to unique obesity characteristics that increase health risks even at lower BMI levels [4][5]. Group 1: Research Findings - The research led by Dr. Simar S. Bajaj indicates that Asians are prone to central obesity, which poses higher health risks such as type 2 diabetes and cardiovascular diseases, even with a lower BMI [5]. - The study advocates for the establishment of specific BMI thresholds for Asian populations, highlighting the necessity for further research to determine exact values [5]. - Current global obesity diagnostic standards may undergo significant changes based on these findings, as the study suggests that existing standards do not adequately reflect the health risks faced by Asians [5]. Group 2: Current Standards and Discrepancies - The World Health Organization (WHO) has not set a unified standard for obesity in Asia, allowing countries to adjust their standards based on local health risks, leading to significant discrepancies among countries like India and China [7]. - In the United States, there is ongoing debate regarding the classification of Asian populations under a single BMI standard, with some organizations proposing adjustments to the BMI thresholds for Asian individuals [8][9]. - The American Diabetes Association (ADA) and the American Society for Metabolic and Bariatric Surgery (ASMBS) have suggested lowering the BMI screening thresholds for Asians to 23 kg/m² and 27.5 kg/m² respectively [9]. Group 3: Implications for Future Research - Recent studies indicate that different Asian ethnic groups exhibit varying diabetes risk levels at the same BMI, challenging the notion of a homogeneous Asian population regarding obesity risk [11]. - A large-scale study involving 147,000 participants confirmed that the BMI threshold for diabetes risk differs significantly among ethnic groups, necessitating a more nuanced approach to obesity standards [11]. - The research highlights the importance of incorporating additional metrics such as waist circumference and waist-to-hip ratio, especially for populations with a BMI of 23 or higher, to enhance the precision of obesity assessments [11].
