The overall goal of this randomized controlled trial is to test the efficacy of a culturally and linguistically modified, individually-tailored lifestyle intervention to reduce risk factors for type 2 diabetes and cardiovascular disease among postpartum Hispanic women with a history of abnormal glucose tolerance during pregnancy.
Specific aims are to evaluate the impact of the intervention on 1) postpartum weight loss, 2) biomarkers associated with insulin resistance (i.e., glucose, insulin, HbA1c, leptin, TNF-α, HOMA, AUCgluc, adiponectin), 3) other cardiovascular risk factors (i.e., blood lipids, blood pressure, CRP, fetuin-A, albumin-to-creatinine ratio), and 4) the adoption and maintenance of postpartum behaviors associated with weight loss and prevention of diabetes risk (i.e., physical activity, diet). Eligible Hispanic women will be recruited after routine GDM screening and randomly assigned to a Lifestyle Intervention (n=150) or a Comparison Health and Wellness (control) intervention (n=150). The intervention will be based on our efficacious exercise and dietary interventions for Hispanics (R01NR011295; WIC Common Pathways). Multimodal contacts (i.e., in-person, telephone counseling, and mailed print-based materials) will be used to deliver the intervention from randomization (29 wks gestation) to 12 months postpartum. Targets of the intervention are to achieve Institute of Medicine Guidelines for postpartum weight loss; American College of Obstetrician and Gynecologist guidelines for physical activity; and American Diabetes Association guidelines for diet. The intervention draws from Social Cognitive Theory and the Transtheoretical Model and addresses the specific social, cultural, economic, and physical environmental challenges faced by underserved Hispanic women. Measures of adherence will include the Pregnancy Physical Activity Questionnaire (PPAQ), accelerometers, and dietary recalls. The project is a Renewal Application of R01 DK064902, a study of lifestyle risk factors for GDM in Hispanic women. The proposed project builds upon the expertise of the investigative team in conducting randomized controlled trials of lifestyle interventions among Hispanic pregnant women (R01 DK074876; S3948 ASPH/CDC) and controlled trials of lifestyle interventions among low-income Hispanics with type 2 diabetes and pre-diabetes (R18 DK0658850; R18DK067549) and can readily be translated into clinical practice in underserved and minority populations.

| Measure | Description | Time Frame |
|---|---|---|
| Postpartum weight change | Postpartum weight change will be measured as the difference between weight at 6 or 12 mos postpartum and weight at delivery. Weight will be measured on a digital scale. | 6 weeks postpartum, 6 months postpartum, 12 months postpartum |
| Percent of participants meeting postpartum weight goals | Postpartum weight goals will be defined as weight change to prepregnancy weight if prepregnancy BMI was normal, or a 5% change towards prepregnancy weight if prepregnancy BMI was overweight/obese. Weight will be measured on a digital scale. | 6 weeks postpartum, 6 months postpartum, 12 months postpartum |
| Fasting Glucose (FG) | Fasting Glucose (FG) will be measured enzymatically on the Roche P Modular system using Roche Diagnostics reagents (Indianapolis, IN)(mg/dL). | 6 weeks postpartum, 6 months postpartum, 12 months postpartum |
| Fasting Insulin (FI) | Fasting Insulin (FI) will be measured by an electrochemiluminescence immunoassay on the Roche E Modular system in uU/mL. | 6 weeks postpartum, 6 months postpartum, 12 months postpartum |
| Hemoglobin A1c (HbA1c) | The Hemoglobin A1c (HbA1c) determination on the Roche P Modular system will be based on turbidimetric immunoinhibition using packed red cells. | 6 weeks postpartum, 6 months postpartum, 12 months postpartum |
| Leptin | Leptin will be measured by an ultra-sensitive ELISA assay, an enzymatically amplified "two-step" sandwich-type immunoassay (R&D Systems, Minneapolis, MN) (pg/mL). |
