Healthy Babies Through Infant Centered Feeding (HB)

Poor feeding practices during infancy contribute to obesity risk because they interfere with infant feeding self-regulation and appropriate growth patterns as infants transition from human milk and/or formula-based diets to solid foods. The goal of the project is to provide an educational intervention that fosters appropriate maternal responsiveness, feeding styles, and feeding practices via infant-centered feeding.

Study Overview

• Status: Completed
• Conditions: Obesity; Overweight; Feeding Behavior; Feeding Patterns; Infant Overnutrition
• Intervention / Treatment: Behavioral: Healthy Babies; Behavioral: Expanded Food and Nutrition Education Program

Detailed Description

The long-term goal of this integrated project is to contribute to curbing the rising rates of childhood obesity through an effective, multi-component, relationship skill-building and educational intervention that fosters infant-centered feeding to promote appropriate maternal responsiveness, feeding styles, and feeding practices as infants transition to solid foods.

Research Objectives: To evaluate effectiveness of Healthy Babies (HB) compared to the Expanded Food and Nutrition Education Program (EFNEP) at two points in time (when the infant is 6 and 12 months of age) for mothers of infants on maternal responsiveness, feeding style, and feeding practices as infants' transition to solid foods, and to compare infant feeding self-regulation and growth pattern of infants at 6 and 12 months of age between the two groups, HB and EFNEP.

Hypothesis: Compared to mothers of infants who receive traditional EFNEP lessons, mothers who receive HB lessons will achieve an improvement (when the infant is 6 months old that is sustained over time when the infant is 12 months of age) on:

• Maternal responsiveness (measured by appropriately interpreting and responding to infant cues when transitioning their infants to solid foods on the Parent-Child Interaction-Feeding Scale [PCI-F]).
• Maternal feeding styles (measured by feeding beliefs and behaviors on the Infant Feeding Styles Questionnaire).
• Feeding practices (measured by use of appropriate feeding practices when transitioning their infants to solid foods on the PCI-F).

Research Question: How do infants in the HB (intervention) group compare to the infants in the traditional EFNEP group when the infant is 6 and 12 months old on:

• Infant feeding self-regulation (measured by clarity of cues and feeding responsiveness on the PCI-F).
• Infant growth patterns (measured by growth charts).

Extension Objective: To evaluate feasibility, fidelity, and educational effectiveness of the HB intervention. (Process Evaluation)

Research Question: What is the feasibility of integration within Extension by paraprofessionals who deliver HB and for mothers of infants' who receive the HB lessons, related to:

• Paraprofessionals' training, ability to deliver the intervention (fidelity), and satisfaction with the intervention; and
• Mothers' acceptance (recruitment), completion (retention), and satisfaction with the intervention.

Research Question: What is the educational effect of the intervention on maternal knowledge, attitudes, and self-efficacy related to infant feeding?

Research Design. The study will use a randomized clinical trial design in which participants from Michigan (MI) and Colorado (CO) will be randomly assigned to the HB intervention or control (EFNEP) group. The HB intervention, delivered by paraprofessionals (educators), is designed to foster appropriate maternal responsiveness, feeding style, and feeding practices. Participants will be blinded to their group assignment. Data will be collected at three time points by a separate data collection team (not educators): baseline (before the first lesson), follow-up (when infant is six months old), and post follow-up (when infant is 12 months old). These time points have been selected based on the infant's age, such that when an infant is six months old, this is the usual time frame when introducing solid food is recommended to be initiated for all infants, and at 12 months, infants should have an established eating pattern of solid foods. Thus, these points in time were selected rather than immediately following the lessons for consistency in infant age. The age of the infant at time of enrollment will be standardized for timing of the intervention, such that the intervention will begin for all infants between 1 and 4 months of age. Three time points are included to make statistical comparisons and assess the sustainability of changes. Process data will be collected throughout the study.

Participant Recruitment. A total of 546 mother-infant were recruited through community agencies providing services to pregnant women and mothers of infants in Michigan and Colorado (i.e., EFNEP, Breast Feeding Initiative, and Women, Infants and Children's Special Supplemental Nutrition Program for Women, Infants, and Children). Given each state's demographics, Michigan is has a higher proportion of Black minority dyads and Colorado a higher proportion of Hispanic/Latina dyads. Though race/ethnicity/culture is not a specific focus of the study, the sample size will allow us to examine race/ethnic/cultural similarities and differences.

The investigators have recruited of 546 eligible families in MI and CO which will allow for 25% attrition (at each data collection), leaving 278 families at post follow-up (when infant is 12 months old) available for data analysis.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Healthy Babies; Participants receive the Healthy Babies curriculum via 6 in home lessons and 3 follow up telephone calls delivered by Extension paraprofessionals.	Behavioral: Healthy Babies; Each lesson is designed to promote the development of healthy infant eating, and incorporates research-based information, opportunities for mothers to develop and practice skills, and a discussion of strategies to overcome challenges and problem-solving techniques. During lessons, mothers engage in activities in support of lesson goals. Intervention strategies focusing on feeding practices will include modification of the feeding environment (e.g., television off during feeding). The telephone contacts, 10 minutes in length, made at 6, 8, and 10 months, reinforce key concepts in the lessons after conclusion of the intervention to maintain effects.
Active Comparator: EFNEP; Participants receive the Expanded Food and Nutrition Education Program (EFNEP) curriculum via 6 in home lessons delivered by Extension paraprofessionals.	Behavioral: Expanded Food and Nutrition Education Program; Core EFNEP concepts are United States Department of Agriculture (USDA) My Pyramid, fruits, vegetables, meats, whole grains, food safety, and food resource management. Educators for the EFNEP group will use the EFNEP lessons which address basic knowledge customized for families with infants. Mothers in the EFNEP group will receive a series of six lessons from the nutrition education program offered in each state; they provide a series of lessons focused on nutrition education for families and do not include extensive content on feeding infants.
