The Blossom Project: "Be-Well" Behavioral Wellness Study in Pregnancy (Be-Well)

Brief Summary:
Multiple studies have demonstrated a very low prevalence of women meeting physical activity and weight gain recommendations during pregnancy. The aim of this study is to provide a lifestyle intervention to increase physical activity, reduce carbohydrate intake, prevent excessive gestational weight gain, decrease postpartum weight retention, and improve mental well-being compared to "usual care" using a randomized controlled design in pregnant women. Participants in the intervention group will receive behavioral lifestyle counseling and take part in monthly one-on-one visits with a registered dietitian (RDN) from approximately week 14 of their pregnancy to child birth. Participants in the "usual care" group (control) will not receive any lifestyle counseling. Data collected from this group will be used to compare the effectiveness of the lifestyle intervention. Unlike many studies examining diet and physical activity factors alone, this study evaluates additional psychosocial factors such as psychological health, self-efficacy, competence, motivation and barriers that may influence excessive gestational weight gain. In addition, the Self-Determination Theory framework will be used to measure how motivation and motivational interviewing strategies can help explain changes in volitional behavior.

Arm Intervention/treatment
Experimental: Behavioral Lifestyle counseling
Intervention group participants will take part in behavioral lifestyle counseling provided by a Registered Dietitian Nutritionist from week 14 of gestation through childbirth.
Behavioral: Behavioral Lifestyle counseling
Participants in the intervention group will take part in one-on-one visits with a registered dietitian nutritionist (RDN) from no later than week 14 to child birth at the OBGYN clinic where the participant receives her routine prenatal care or the Nutrition Wellness Research Center in the Iowa State Research Park. These visits will be coordinated with her routine prenatal appointment; therefore a minimum of 6 face-to-face meetings will occur. The counseling sessions will focus on appropriate weight gain during pregnancy through the use of an individualized meal plan, physical activity goals, and behavioral modification. Weight gain will be plotted on an IOM weight gain chart and discussed with study RDN.

Active Comparator: Control
Participants in the control arm will receive no form of lifestyle intervention.
Other: Control
Participants in the control arm will receive no form of lifestyle intervention. Women will be provided with usual care by their physician. Participants in the control arm will have their weight gain plotted on an IOM growth chart and sent electronically by research staff after each routine prenatal appointment. No other feedback on weight gain or behavior modification will be provided by the study RDN.

Primary Outcome Measures :
  1. Maternal Body Weight Change [ Time Frame: From 14 weeks of gestation through 2 months post partum ]

    Gestational weight gain as measured by last pre-delivery weight minus self-reported pre-pregnancy weight.

    Maternal weight will be measured at each routine prenatal appointment and plotted on the IOM pregnancy weight gain chart.

    Body composition changes measured by BodPod at baseline and 2 months postpartum.

Secondary Outcome Measures :
  1. Maternal Postpartum Depression and Perceived Quality of Life [ Time Frame: Baseline through 2 months post partum ]

    World Health Organization Quality of Life questionnaire that measure physical health, psychological health, social relationships and environment.

    The Edinburg Postnatal Depression Scale

  2. Maternal Insulin Resistance [ Time Frame: Maternal 26th-28th week of gestation ]
    Plasma glucose concentrations and insulin resistance as measured from a oral glucose tolerance test.

  3. Postpartum Weight Retention [ Time Frame: From 14 weeks of gestation through 2 months post partum ]
    The difference between the weight at 2 months postpartum and the pre-pregnancy weight.

Other Outcome Measures:
  1. Infant Outcomes [ Time Frame: 2 months post partum ]

    Characteristics at birth including Apgar score, gestational age.

    Body composition (i.e. length, percent lean and fat mass) 2 months postpartum.
