To test the feasibility and effectiveness of a Web-based lifestyle intervention based on the Diabetes Prevention Program modified for women with recent gestational diabetes mellitus to reduce postpartum weight retention.


We randomly allocated 75 women with recent gestational diabetes mellitus to either a Web-based lifestyle program (Balance after Baby) delivered over the first postpartum year or to a control group. Primary outcomes were change in body weight at 12 months from 1) first postpartum measured weight; and 2) self-reported prepregnancy weight.


There were no significant differences in baseline characteristics between groups including age, body mass index, race, and income status. Women assigned to the Balance after Baby program (n=36, three lost to follow-up) lost a mean of 2.8 kg (95% confidence interval -4.8 to -0.7) from 6 weeks to 12 months postpartum, whereas the control group (n=39, one lost to follow-up) gained a mean of 0.5 kg (-1.4 to +2.4) (P=.022). Women in the intervention were closer to prepregnancy weight at 12 months postpartum (mean change -0.7 kg; -3.5 to +2.2) compared with women in the control arm (+4.0 kg; +1.3 to +6.8) (P=.035).


A Web-based lifestyle modification program for women with recent gestational diabetes mellitus decreased postpartum weight retention.
