Avoiding Diabetes After Pregnancy Trial (ADAPT)
Increasing Adoption of Early Intervention to Prevent Diabetes After Gestational Diabetes Mellitus
The Avoiding Diabetes After Pregnancy Trial (ADAPT) study was designed to test the effectiveness of interventions that potentially increase the adoption of Diabetes Prevention Program (DPP) elements by women who had a pregnancy with gestational diabetes mellitus (GDM).
The study was conducted as an integrated trial with two separate arms: one to facilitate weight reduction and the other to increase diabetes testing.
There were two hypotheses:
- Women in the testing intervention will be more likely to have received a diabetes test within the 6 months post-intervention than women in the control group.
- Women in the weight reduction intervention will have lost more weight at the 6-month and 9-month follow-up than women in the control group.
The primary study aim was to determine the efficacy of a system of interactive technology-based supports to prompt women with a history of gestational diabetes to take steps to prevent diabetes. The secondary aims were focused on women's engagement:
- To evaluate the impact of the weight reduction intervention in terms of participant engagement with the interactive technology-based supports.
- To evaluate changes in the women's perception of their personal diabetes risk following after exposure to information about diabetes risk following a pregnancy with GDM.
- To identify the determinants and motivators of and barriers to diabetes testing in the 6- to 12-week postpartum period and thereafter, using the Health Belief model to guide the study.
There was an additional secondary aim involving metformin:
- To evaluate the impact of the diabetes risk reduction intervention in terms of women seeking out their physician's advice on metformin treatment and receiving a metformin prescription, if appropriate.

Armas e Intervenções
Grupo de Participantes / Braço |
Intervenção / Tratamento |
|---|---|
|
Experimental: Weight Reduction Intervention
|
The weight trial intervention components were:
|
|
Comparador Ativo: Weight Reduction Control Arm
|
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.
|
|
Comparador Ativo: Tested for 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.
|
|
Comparador Ativo: Not tested for 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 subsample of those not 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.

O que o estudo está medindo?
Medidas de resultados primários
Medida de resultado |
Descrição da medida |
Prazo |
|---|---|---|
|
For participants in weight group, weight reduction from baseline to 6 months
Prazo: 6 months
|
Participants reported their weights online at baseline, 3 months, 6 months, and 9 months, and the difference in weight from baseline to 6 months was the primary measure of the intervention's success.
|
6 months
|
|
In testing group, the number of women receiving a diabetes test per ADA Guidelines in the 6-month post-intervention period
Prazo: 6 months
|
The number of women who were tested in the 6 months following the intervention was determined from electronic medical records.
|
6 months
|
Medidas de resultados secundários
Medida de resultado |
Descrição da medida |
Prazo |
|---|---|---|
|
Weight intervention participant engagement with the interactive technology-based supports
Prazo: 9 months
|
Measured by separate scores for taking part in behavioral support (coaching calls) and electronic feedback (women responding on goal performance via daily text messaging (SMS)or weekly IVR, chosen by the participant).
|
9 months
|
|
Success of participants in weight intervention arm in achieving behavior change goals.
Prazo: 9 months
|
Information from daily SMS and weekly IVR responses to questions about participants' success in achieving behavior change goals were used to construct achievement scores.
|
9 months
|
|
Weight change from baseline to 9 months
Prazo: 9 months
|
Differences were calculated in weights entered on baseline and 9-month surveys for intervention and control arms in the weight group.
|
9 months
|
|
Weight change from 6 to 9 months
Prazo: 3 months
|
Difference in weights recorded in 6-month and 9-month questionnaires was calculated for all participants in the weight group.
|
3 months
