A Home-based Intervention to Improve the Diet Quality of Preschoolers

U.S. children eat too little fruits and vegetables and whole grains, and too many energy dense foods, dietary behaviors associated with increased morbidity from cardiovascular diseases. Parents play a key role in shaping their child's diet and best practices suggest that parents should involve children in food preparation, offer, model and encourage a variety of healthy foods. In addition, while parents help to shape food preferences, not all children respond in the same way and certain appetitive traits, such as satiety responsiveness (sensitivity to internal satiety signals), food responsiveness (sensitivity to external food cues), and enjoyment of food may help explain some of these differences. Prior interventions among preschool aged children to improve their diet have not used a holistic approach that fully targets the home food environment, by focusing on food quality, food preparation, and positive feeding practices while acknowledging a child's appetitive traits. This proposal will build upon pre-pilot work to develop and pilot-test the feasibility, acceptability and preliminary efficacy of a novel home-based intervention. The proposed 6-month intervention, will include 3 monthly home visits by a community health worker (CHW) trained in motivational interviewing, that include in-home cooking demos. In between visits, parents will receive tailored text-messages 2x/wk. and monthly mailed tailored materials. During the last 3 months CHW phone calls will replace the home visits. The intervention will be tailored for individual families based on the child's appetitive traits. The proposed research will lay the groundwork for a larger trial to support, motivate, and empower low-income parents to prepare healthy meals and use healthy feeding practices, which will improve children's diets and ultimately their health.

About this study

There is a critical need for primary prevention interventions to help parents shape children's dietary behaviors early in life. These interventions need to be convenient for busy, working families and tailored to children's needs and the family environment. Although there have been several interventions among preschool aged children to improve dietary behaviors, none have used a holistic approach that fully targets the home food environment, by focusing on food quality, food preparation, and positive feeding practices while acknowledging a child's appetitive traits. The proposed research will develop and pilot-test the feasibility, acceptability and preliminary efficacy of a novel home-based intervention to improve the diet quality and family food environment of high-risk preschool age, low-income, ethnically diverse children. This research will build upon previous research including a pre-pilot intervention with 15 mother-child dyads which included two home visits: the first visit included a meal-recording and the second included a motivational interviewing (MI) session using coded video clips from the meal-recording as feedback on the parents' feeding practices. All families were retained and significant improvements in several parental feeding practices were found. Based on lessons learned in the pre-pilot, the proposed 6-month intervention will include home visits by a community health worker (CHW) trained in MI, enhanced by adding several innovative components. The home visits will include in-home cooking demonstrations; tailored text-messages, mailed materials and CHW phone calls. The intervention will be tailored for families based on the child's appetitive traits and eating behaviors. These strategies are expected to increase parental knowledge, self-efficacy, and motivation for serving easy, inexpensive healthy foods in the home, leading to increased child exposure to more healthy and varied foods, improvements in parental feeding practices, and ultimately, improvements in child diet quality. The specific aims are as follows:

Aim 1: To conduct focus groups with 40 ethnically diverse low-income parents of preschoolers (2-5 years) to inform the adaptation and development of the enhanced intervention.

Aim 2: To conduct a pilot randomized controlled trial with 60 parent-child pairs (30 intervention/30 control) from ethnically diverse, low-income families with preschoolers to:

Aim 2.1 Determine the feasibility and acceptability of the enhanced intervention.

Aim 2.2 Determine the preliminary efficacy of the enhanced intervention on changes in children's diet quality (primary outcome) and parental feeding practices and availability of healthy foods in the home (secondary outcomes) and calculate effect sizes for a future randomized controlled trial (RCT).

The investigators hypothesize that the intervention will be feasible and acceptable to parents and that parent-child pairs randomized to the intervention condition will demonstrate greater improvements in the outcomes after six months compared to the comparison condition (attention control of a school readiness intervention).

Exploratory aim: Explore how parents' skills, self-efficacy and intrinsic motivation are related to changes in children's diet quality and parental feeding practices.

Primary outcomes

  1. HEI-2015 Total and Component Scores

    Time frame: Healthy Eating Index Scores at study completion (6 months)

    HEI-2015 scores will be calculated from twenty four hour recall data (two of them which are combined and scored per 1000 kcal or as a % of intake per NCI scoring guidelines). HEI was designed to measure diet quality in terms of how well diets conform to the 2015 Dietary Guidelines for Americans. The total HEI score represents the sum of 12 components scores (minimum component can be 0 and maximum component score shown in parentheses for each), including total fruit (5), whole fruit (5), total vegetables (5), green and beans (includes dark green vegetables and cooked, dried beans and peas because intakes of these types of vegetables are furthest from the amounts recommended in the USDA Food Patterns) (5), whole grain (10), dairy (10), total protein food (5), seafood and plant proteins (5), fatty acids (10), refined grains (10), sodium (10) added sugar (10), saturated fat (10). Higher scores reflect better outcomes.

Secondary outcomes

  1. Food Parenting Practices

    Time frame: Food Parenting Practices at study completion (6 months)

    The intervention effects on 14 subscales of the Food Parenting Inventory were used as secondary outcome measures: Encourage try new foods (P), Encourage exploration of new foods (P), Urge child to eat new foods (P), Repeated Presentation of New foods (P), Family meals (P), Regular timing of meals and snacks (P), Inconsistent mealtimes (N), Indifferent feeding (N), Child involvement in food preparation (P), Pressure to Eat (N), Restriction (N), Food as a reward (N), Responsiveness to child's fullness cues (P), Monitoring (P). We also use one subscale of the Comprehensive Feeding Practices Questionnaire: Healthy Eating Guidance (P). All scales are rated on a 5-point Likert scale ranging from 1 (min) to 5 (max). Higher subscale scores indicate greater use of that child feeding practice. We have noted which practice has more positive/desirable practices with a (P) and more negative/not desired sub-scales have an (N) with higher scores.

Other outcomes

  1. Home Food Availability Change

    Time frame: Changes in Home Food Inventory Scores between baseline and study completion at 6 months

    Home Food Inventory Change Scores. Home food inventory (HFI) will be used to assess a wide range of commonly available foods in the home environment. A total healthy food availability score will be created from the following items (fruit- frozen, canned, fresh or dried, vegetables-frozen, fresh or canned, milk, water, whole grains, legumes) with a higher score representing more availability of healthy foods. Scores can range from 0-11. An unhealthy food score will also be created from the following items (Chips, Cakes/Cookies, Candy, Pastries, Juice, Soda, Sports drinks, Sweetened Beverages)- scores can range from 0-8 with higher scores representing availability of unhealthy foods.
