About this trial

This is an interventional prevention trial for Gestational Diabetes

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)FemaleDoes not accept healthy volunteers

Inclusion Criteria:

  1. Pregnant women receiving prenatal, delivery, and postpartum care at Tufts Medical Center
  2. Gestational diabetes diagnosed between 14 0/7 and 31 6/7 weeks gestation on basis of 1-hour glucose challenge test result of >=200 mg/dL or Carpenter-Coustan criteria
  3. >= 18 years of age
  4. Literate in English or Spanish (?additional languages pending app translation)
  5. Access to or ownership of a smartphone compatible with Malama
  6. Willing and able to sign the informed consent

Exclusion Criteria:

  1. Unable to tolerate oral glucose tolerance test (i.e. history of gastric bypass surgery)
  2. Diagnosis of pregestational diabetes
  3. Prescribed medications for chronic disease that affect glucose metabolism (e.g., long term oral steroids)
  4. Does not own smartphone compatible with Malama application
  5. Severe life-limiting fetal anomaly

Arms of the Study

Arm 1

Arm 2

Arm Type

Experimental

No Intervention

Arm Label

Malama Arm

Control

Arm Description

Participants enrolled in this arm will agree to using the Malama app to track glycemic management.

Participants enrolled in this arm agree to standard management (FS log on phone, notebook, etc)

Outcomes

Primary Outcome Measures

Malama app as intervention
The primary aim of the study is to investigate if the incidence of postpartum glucose intolerance is lower in patients using the Malama app for gestational diabetes management compared to patients receiving standard care.

Secondary Outcome Measures

Postpartum hemoglobin A1c level
We will be measuring the postpartum A1c level to capture whether the mobile health app influences blood glucose levels based on glycemic control log method (app for intervention arm, pen-and-paper log for control).

5. Study Description

Brief Summary
Without intervention, approximately 70% of women diagnosed with GDM will develop type 2 diabetes mellitus in their lifetime. Abnormal results of a 2 hour oral glucose tolerance test (OGTT) performed as early as 2 days postpartum are predictive of impaired glucose tolerance 1 year postpartum. The investigators hypothesize that use of the Malama smartphone application to optimize antenatal glycemic control will result in lower incidence of postpartum glucose intolerance, which may decrease long term risk of progression to diabetes mellitus.
Detailed Description
The effect of smartphone applications for gestational diabetes management on risk of postpartum glucose intolerance, antenatal glycemic control, and other perinatal outcomes is unknown. This study is a randomized control trial in which patients diagnosed with gestational diabetes will be randomized to use of the Malama app vs. standard care as described above. The primary aim of the study is to investigate if the incidence of postpartum glucose intolerance is lower in patients using the Malama app for gestational diabetes management compared to patients receiving standard care. Secondary outcomes that will be investigated include several markers of maternal and neonatal perinatal morbidity. Maternal outcomes that will be investigated include postpartum hemoglobin A1c level, interval pregnancy weight gain, incidence of hypertensive disorders of pregnancy, cesarean delivery, operative delivery, postpartum hemorrhage, and advanced perineal lacerations. Neonatal secondary outcomes include gestational age at delivery, birthweight and incidence of large for gestational age infants, shoulder dystocia, NICU admission, length of NICU stay, neonatal blood glucose nadir, and need for neonatal IV glucose support.

Intervention Name(s)
Malama App
Intervention Description
The Malama smartphone application is a gestational diabetes management app that syncs directly with commercially-available glucometers via Bluetooth, enabling both automatic blood glucose logging and providing interactive diet management/diet education tools. We aim to perform a pilot study assessing the impact of the Malama smartphone application on perinatal and postpartum outcomes in patients with GDM.
Primary Outcome Measure Information:
Title
Malama app as intervention
Description
The primary aim of the study is to investigate if the incidence of postpartum glucose intolerance is lower in patients using the Malama app for gestational diabetes management compared to patients receiving standard care.
Time Frame
8-26 weeks
Secondary Outcome Measure Information:
Title
Postpartum hemoglobin A1c level
Description
We will be measuring the postpartum A1c level to capture whether the mobile health app influences blood glucose levels based on glycemic control log method (app for intervention arm, pen-and-paper log for control).
Time Frame
6 months
