WHtR-BFP dual-dimensional synergy: innovative construction of a nine-grid model for precision obesity management (opens in new tab)

IntroductionCurrent obesity assessment tools often capture either fat distribution or overall adiposity, limiting precise risk stratification and individualized management. To address this gap, we developed a dual-dimensional framework for obesity assessment and tiered intervention.MethodsGuided by Multidimensional Health Management Theory and the Stages of Change Theory, we constructed the waist-to-height ratio (WHtR)-body fat percentage (BFP) Dual-Dimensional Synergistic Nine-Grid Model. Us...
