Core Viewpoint - The article emphasizes the importance of waist-to-height ratio (WHtR) as a superior metric for assessing obesity-related metabolic risks compared to traditional body mass index (BMI) measurements, highlighting its advantages in clinical practice and recent guideline updates [6][10][12]. Group 1: Obesity and Metabolic Disorders - The obesity rate among adults in China has surpassed 50% and is projected to reach 61% by 2030, indicating a serious public health challenge [8]. - Obesity is linked to various metabolic disorders, including dyslipidemia, insulin resistance, and chronic inflammation, which can lead to severe diseases such as chronic kidney disease, cardiovascular diseases, type 2 diabetes, and certain cancers [8]. Group 2: Waist-to-Height Ratio Advantages - Waist-to-height ratio (WHtR) is highlighted for its significant advantages over BMI, including better correlation with visceral fat accumulation and broader coverage of metabolic disorders [6][10]. - WHtR demonstrates higher diagnostic sensitivity and specificity for identifying obesity-related diseases, particularly in women, and effectively addresses the limitations of BMI [10]. Group 3: Clinical Guidelines and Standards - Recent international guidelines suggest a paradigm shift in obesity diagnosis, incorporating WHtR into the assessment criteria, thus moving from a weight-centric approach to a comprehensive metabolic risk evaluation [12][13]. - The updated diagnostic pathways include multiple metrics for confirming obesity, enhancing the precision of identifying high-risk individuals [13].
