aMean changes estimated by paired t-test within completers, or by marginal means from GEE models for daily accelerometer MVPA (which was back-transformed from the log scale and multiplied by 7 yield minutes/week).
bItalic values indicate statistical significance at P˂.05.
cn=103 GHSH group; n=112 control group (item missing data for waist circumference).
dn=99 GHSH group; n=108 control group; some participants did not wear the accelerometer.
