Avoiding Diabetes After Pregnancy Trial

"The weight trial intervention components were:~* Electronic feedback from the ADAPT interactive obesity treatment approach (iOTA) system, tracking participants' behavior change goals. Participants received feedback either by daily SMS (text messaging) or by weekly IVR (interactive automated calls).~* Seven behavior change coaching calls, once a month for 6 months, and then one at 7.5 months halfway through the maintenance period.~* Print mailings/emailings~* 3 Get Ready e-messages in the four weeks before the weight intervention began~* Pedometers and program guides. (IVR users received printed activity logs with their program guides.)~* Access to the ADAPT iOTA website for reviewing their progress and obtaining information on behavior change goals."

Participants received an initial brochure about managing diabetes risk, a digital scale to use in entering their weights in online questionnaires, and monthly emailed wellness messages unrelated to diabetes.

Due to small numbers in this group, the planned intervention was changed to a mixed-mode study, using baseline and follow-up self-administered questionnaires and semi-structured questionnaires administered to a sub-sample of those tested for diabetes to identify factors differentiating the behavior of women who had and had not been tested for diabetes following a pregnancy with gestational diabetes mellitus.
