Differential Physical Activity Responses to Diabetes Risk Reduction Interventions According to Prediabetes Phenotype: Insights from Pooled Randomized Controlled Trials

Lifestyle interventions increase physical activity and reduce diabetes risk variably across prediabetes phenotypes.
Individuals with impaired glucose tolerance and combined IFG+IGT show greater physical activity gains than those with isolated IFG.
Structured group-based interventions with goal setting effectively enhance step counts, particularly in IGT and IFG+IGT groups.
Emerging digital and AI-driven interventions provide scalable alternatives with comparable efficacy in improving activity and metabolic outcomes.
