However, the differences between PA and diet in prediabetic and normoglycemic individuals remain unclear.<h4>Methods</h4>A cross-sectional study was conducted on Chinese adults without diabetes, who attended the Third Affiliated Hospital of Sun Yat-sen University in Guangzhou from December 2023 to August 2024. Participants were divided into the preDM group (n = 151) or the normoglycemic group (n = 302). We assessed diet using the Planetary Health Diet Score (PHD-S), which was derived from a Food Frequency Questionnaire (FFQ) reflecting the past year, and PA using one-week reBMC public healthComparative analysis of dietary and physical activity behavior between prediabetic and normoglycemic populations.PMC12506380722042772025A1515012706YHJH202404YJYZ202304Guo XGao LHu XLin JLiu SfalseComparative analysis of dietary and physical activity behavior between prediabetic and normoglycemic populations.<h4>Background</h4>The prevalence of prediabetes (preDM) is rising among adults, and lifestyle factors such as physical activity (PA) and diet play a critical role in preventing or delaying the progression to diabetes.
