About this study

Official title: Estudio PARTO: Proyecto pAra Reducir Diabetes Tipo dOs / Project Aiming to Reduce Type twO Diabetes

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.

Read the detailed description

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: 6 weeks postpartum, 6 months postpartum, 12 months postpartum

  2. 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.

    Measured: 6 weeks postpartum, 6 months postpartum, 12 months postpartum

  3. Fasting Glucose (FG)

    Fasting Glucose (FG) will be measured enzymatically on the Roche P Modular system using Roche Diagnostics reagents (Indianapolis, IN)(mg/dL).

    Measured: 6 weeks postpartum, 6 months postpartum, 12 months postpartum

  4. Fasting Insulin (FI)

    Fasting Insulin (FI) will be measured by an electrochemiluminescence immunoassay on the Roche E Modular system in uU/mL.

    Measured: 6 weeks postpartum, 6 months postpartum, 12 months postpartum

  5. Hemoglobin A1c (HbA1c)

    The Hemoglobin A1c (HbA1c) determination on the Roche P Modular system will be based on turbidimetric immunoinhibition using packed red cells.

    Measured: 6 weeks postpartum, 6 months postpartum, 12 months postpartum

  6. 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).

    Measured: 6 weeks postpartum, 6 months postpartum, 12 months postpartum

  7. Total Adiponectin

    Total Adiponectin (Multimeric) will be measured using an ELISA method from ALPCO Diagnostics Inc. (Salem, NH).

    Measured: 6 weeks postpartum, 6 months postpartum, 12 months postpartum

  8. Lipoprotein Profile

    Lipoprotein Profile: will be simultaneously performed on the Roche P Modular system. Total Cholesterol will be measured enzymatically (mg/dL). Triglycerides will be measured enzymatically with correction for endogenous glycerol (mg/dL). The concentration of High Density Lipoprotein Cholesterol will be determined using a direct enzymatic colorimetric assay (mg/dL). Low Density Lipoprotein Cholesterol will be determined by a homogenous direct method (mg/dL).

    Measured: 6 weeks postpartum, 6 months postpartum, 12 months postpartum

  9. High Sensitivity C-Reactive Protein

    The concentration of High Sensitivity C-Reactive Protein (hsCRP) will be determined using an immunoturbidimetric assay on the Roche P Modular system using reagents and calibrators from DiaSorin (Stillwater, MN) (mg/L).

    Measured: 6 weeks postpartum, 6 months postpartum, 12 months postpartum

  10. TNF

    TNF-receptor II is measured by an ELISA assay from R\&D Systems (pg/mL).

    Measured: 6 weeks postpartum, 6 months postpartum, 12 months postpartum

  11. Albumin-to-creatinine ratio (ACR)

    Albumin-to-creatinine ratio (ACR): Albumin will be measured by a colorimetric assay, an automated dye-binding method using the Roche P Modular system and Roche Diagnostics reagents (Indianapolis, IN) (g/dL). Creatinine will be measured by an enzymatic method using the Roche P Modular system and Roche Diagnostics reagents (Indianapolis, IN) (mg/dL).

    Measured: 6 weeks postpartum, 6 months postpartum, 12 months postpartum

  12. Fetuin-A

    Fetuin-A will be measured by an enzyme immunoassay (EIA) (BioVendor - Candler, NC) (ng/mL).

    Measured: 6 weeks postpartum, 6 months postpartum, 12 months postpartum

  13. Physical activity

    Total activity according to intensity will be measured via the Pregnancy Physical Activity Questionnaire (PPAQ) and hip worn accelerometer. (MET-hrs/week).

    Measured: 6 weeks postpartum, 6 months postpartum, 12 months postpartum

  14. Dietary Intake

    Total calories, along with the other nutrients, will be measured via three 24-hr dietary recalls.

    Measured: 6 weeks postpartum, 6 months postpartum, 12 months postpartum
