ILI=intensive lifestyle intervention; DSE=Diabetes Support and Education ; The 4 MVPA groups were compared to one another within a particular treatment arm and assessment time point. Values with similar superscripts indicate that the two groups are not significantly different from one another (p>0.05; e.g., among ILI participants at Year 1, the METs per bout was similar between those with <50 min/week and those with 50-150 min/week of MVPA). All other comparisons were significantly different from one another (p<0.05).
*
METs/bout variable only includes those participants with ≥ 1, 10-minute MVPA bout.
