Delta Healthy Sprouts: Intervention to Promote Maternal Weight Control and Reduce Childhood Obesity in the MS Delta

October 24, 2016 updated by: USDA, Delta Human Nutrition Research Program

Delta Healthy Sprouts: A Randomized Trial to Determine the Comparative Efficacy of Two Maternal, Infant, and Early Childhood Home Visiting Programs on Maternal Weight Control and Childhood Obesity in the Mississippi Delta

The Delta Healthy Sprouts Project is a randomized, controlled trial evaluating the enhancement of an existing Mother, Infant, and Early Childhood Home Visiting Program in 150 African American women in their early second trimester of pregnancy. The control arm, Parents as Teachers, is an evidence-based approach to increase parental knowledge of child development and improve parenting practices. The experimental arm, Parents as Teachers Enhanced, builds on the Parents as Teachers curriculum by including nutrition and physical activity components specifically designed for the gestational and postnatal periods. Both arms of the intervention will be implemented by community-based, trained Parent Educators. The comparative effectiveness of the two intervention arms on weight status, dietary intake, and health behaviors of mothers and their infants will be assessed. The Delta Healthy Sprouts Project will determine if a novel, scalable, lifestyle intervention can improve the health of African American women and their children at high-risk for obesity and chronic disease.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Parents as Teachers Enhanced
Participants in the Parents as Teachers Enhanced (PaTE) intervention arm will receive the enhanced diet and activity maternal, infant, and early childhood home visiting program
Behavioral: Parents as Teachers Enhanced
Participants will receive the same monthly Parents as Teachers (PaT) lessons and materials at each home visit as the PaT arm. Additionally, these mothers will receive the enhanced nutrition and physical activity lessons and materials which will follow the family well-being format of the PaT lessons. The StartSmart lessons will focus on healthy gestational weight gain, diet, physical activity, breastfeeding, weight management, healthy eating, food shopping, meal preparation, physical activity, proper infant feeding, and infant activity time.
Other Names:
  • PaTE
Behavioral: Parents as Teachers
Participants will receive monthly Parents as Teachers (PaT) lessons and materials at each home visit. The Parent Educator will first connect with the mother by discussing or reviewing content from the prior visit; reflect on the mother's experience with continuing the parent-child activity from the prior visit; and agree on what will happen during the current visit. For the lesson plan, the Parent Educator will cover the following three areas using discussion, activities, and handouts: parent-child interaction, develop-centered parenting, and family well-being. In closing, the Parent Educator will review and evaluate the visit, talk about the mother's next step, and plan for the next visit.
Other Names:
  • PaT
Active Comparator: Parents as Teachers
Participants in the Parents as Teachers (PaT) control arm will receive the standard maternal, infant, and early childhood home visiting program
Behavioral: Parents as Teachers
Participants will receive monthly Parents as Teachers (PaT) lessons and materials at each home visit. The Parent Educator will first connect with the mother by discussing or reviewing content from the prior visit; reflect on the mother's experience with continuing the parent-child activity from the prior visit; and agree on what will happen during the current visit. For the lesson plan, the Parent Educator will cover the following three areas using discussion, activities, and handouts: parent-child interaction, develop-centered parenting, and family well-being.
