Brief summary
The purpose of this study is to learn about the impact of the Diabetes Prevention Program (DPP) coupled with intensive breastfeeding support to help overweight or obese pregnant women lose weight postpartum, improve their blood sugars and blood pressure, and increase duration of breastfeeding their infant.
Detailed description
This pilot randomized controlled trial seeks to determine the feasibility and efficacy of a combined breastfeeding, DPP-based program in a cohort of overweight/obese women to be followed during pregnancy through 6 months postpartum. The pilot trial will have three study arms: DPP + breastfeeding (Tx1), DPP only (Tx2), and usual care (Tx3). Specific aims are: 1) To test the efficacy of Tx1 to improve 6-month postpartum weight loss among women with a BMI \>/= 25. 2) To test the efficacy of Tx1 to improve 6-month postpartum mean blood glucose (HbA1c) and mean arterial blood pressure among women with a BMI \>/= 25. 3) To test the efficacy of Tx1 to increase any breastfeeding through 6 months postpartum among women with a BMI \>/= 25.
Interventions
Phase 1 (core curriculum) of the Diabetes Prevention Program consists of 16 sessions and will take place during Week 18 of pregnancy through Week 33. Participants will receive the DPP curriculum via virtual pre-recorded sessions to which participants will have access. A research coordinator will follow up with each study participant by phone once weekly. If participants do not make adequate progress, the coordinator will assess how much extra time the participant will need to complete each session and will work with the participant if needed. Phase 2 (post-core curriculum) consists of 6 sessions and will be completed after delivery, between Week 6 and Week 20 postpartum. Participants will re-engage into the DPP with an orientation session at Week 6 postpartum. The same session completion format and procedure for inadequate progress will be followed as during pregnancy.
Participants will receive a 2-hour session on breastfeeding and participate in a professional peer support group. The breastfeeding session is between Week 20 and Week 36 of pregnancy and will be taught by an International Board Certified Lactation Consultant (IBCLC). Participants will be provided with a breastfeeding assessment at Days 3 and 10; Week 3 and 6; and Months 2, 3, and 6 postpartum.
Participants will receive regular prenatal care provided by their physician. At delivery, all participants will receive some type of lactation support in the hospital.

Secondary
| Measure | Time frame | Description |
|---|---|---|
| Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF, Survey) | At baseline and at 6 months postpartum | To assess levels of self-efficacy. Survey consists of 14 items. All items are preceded by the phrase I can always and are anchored with a 5-point Likert-type scale where 1 indicates not at all confident and 5 indicates always confident. All items are presented positively, and scores are summed to produce a range from 14 to 70, with higher scores indicating higher levels of breastfeeding self-efficacy. |
| Kaiser Physical Activity Survey (KPAS, Weighted Total) | At baseline and at 6 months postpartum | To assess multiple domains of physical activity and total physical activity before and after pregnancy. Survey consists of 38 items; 4 domains: household and family care activities, occupational activities, active living habits, participation in sports/exercise. Activity indices were created for each domain of activity by summing the domain-specific categorical responses and dividing by the number of items, giving an average value that ranged from 1 to 5 (scores ranged from 1 for never or none to 5 for always or more than once a week in each physical activity domain). Higher scores indicate greater overall activity levels. Total activity index is calculated as the sum of all four indices: Total activity = (household/caregiving index\*0.25 + occupational index\*0.25 + active living index\*0.25 + sports/exercise index\*0.25) \* 4. The total activity score has a potential range of 4 - 20 with a mean of 10.42 (SD=2.00). A higher total activity score indicates a greater activity level. |
| Fruit & Vegetable Intake Screener (EATS) | At baseline and at 6 months postpartum | To assess intake of fruits and vegetables before and after pregnancy. Survey consists of 10 items; with portion-size questions. Each question has two parts, asking over the last month how often a particular item was consumed (i.e.: never, 1-3x/mo, 1-2x/wk, etc.) and how much was usually consumed (i.e.: \<3/4cup, 3/4 to 1 1/4 cup, \>2 cups, etc.). Frequency is scored from 0.0-5.0, with 0 meaning never, and 5.0 meaning 5 or more servings per day. |
| Edinburgh Postnatal Depression Scale (EPDS) | Postpartum | To assess levels of depression during the postpartum period. Survey consists of 10 items. Questions 1, 2, & 4 are scored 0, 1, 2 or 3 with top box scored as 0 and the bottom box scored as 3. Questions 3, 5--10 are reverse scored, with the top box scored as a 3 and the bottom box scored as 0. Maximum score is 30. A score of 10 or higher generally indicates a potential need for further assessment regarding possible depression, while scores above 12 or 13 may suggest a higher likelihood of depression requiring medical attention. Participants with a score of 10 or greater will be referred to their healthcare provider for follow up. |

All items are presented positively, and scores are summed to produce a range from 14 to 70, with higher scores indicating higher levels of breastfeeding self-efficacy.

Kaiser Physical Activity Survey (KPAS, Weighted Total)
To assess multiple domains of physical activity and total physical activity before and after pregnancy. Survey consists of 38 items; 4 domains: household and family care activities, occupational activities, active living habits, participation in sports/exercise. Activity indices were created for each domain of activity by summing the domain-specific categorical responses and dividing by the number of items, giving an average value that ranged from 1 to 5 (scores ranged from 1 for never or none to 5 for always or more than once a week in each physical activity domain). Higher scores indicate greater overall activity levels. Total activity index is calculated as the sum of all four indices: Total activity = (household/caregiving index\*0.25 + occupational index\*0.25 + active living index\*0.25 + sports/exercise index\*0.25) \* 4. The total activity score has a potential range of 4 - 20 with a mean of 10.42 (SD=2.00). A higher total activity score indicates a greater activity level.
