- Registration Number
- NCT06570707
- Brief Summary
The purpose of this study is to examine the effects of the (Brighter Bites (BB) intervention compared to a wait-list control group 9 months after the intervention on changes in primary child outcomes (HbA1c, and vegetable intake), on changes in secondary outcomes (household food security status, parent and child dietary behaviors, and home access/availability of fruits and vegetables (FV)), and the mediational influence of changes in food security status, parent outcomes, and home environment measures on changes in child outcomes.
- Detailed Description
The purpose of this study is to examine the effects of the (Brighter Bites (BB) intervention compared to wait-list control at post intervention on changes in primary child outcomes (HbA1c, and vegetable intake), to examine the effects of the BB intervention compared to wait-list control at 9-month post intervention on changes in secondary outcomes (household food security status, parent and child dietary behaviors, and home access/availability of fruits and vegetables (FV)),to examine the mediational influence of changes in food security status, parent outcomes, and home environment measures on changes in child outcomes at 9-month post-intervention, using within-subject analyses, examine and compare the long-term and dose-response effects of the BB intervention strategies on diet, adiposity, and metabolic outcomes at 21-month follow-up in the children and to explore the moderating effects of social and environmental variables on program effectiveness.

Group Intervention Description Brighter Bites Brighter Bites This group will receive the Brighter Bites intervention throughout the study implementation. The intervention includes fruit and vegetable distributions of \~20lbs. for teachers and families, healthy recipe tastings, and nutrition education.
- Primary Outcome Measures
Name Time Method Change in level of child Glycosylated hemoglobin (HbA1c) baseline, post intervention (9 months after baseline) We will utilize the portable HbA1c analyzers (DCA Vantage analyzer) to assess HbA1c, during biometric events.
Change in amount of child vegetable intake as assessed by the VEGGIE METER® baseline, post intervention (9 months after baseline) The VEGGIE METER® is used to obtain a child's quantitative metric of skin carotenoids, a proxy measure of FV intake for children. The VEGGIE METER® measures skin carotenoids as an indicator of FV intake. Higher number of carotenoid levels indicate more FV intake.
- Secondary Outcome Measures
Name Time Method Change in household food security status as assessed by a parent survey baseline, post intervention (9 months after baseline) Household Food Insecurity will be measured using 2-item Hunger Vital Sign food security survey and 4-items adapted from the Center for Nutrition and Health Impact, for a total of 6-items.
The items are scored from 0 (if the participant selects "Always") to 4 (if the participant selects "Never") and the measure's score is the mean of the responses. The higher the participant's score, the greater degree of the household nutrition security.Number of servings consumed by the Child as assessed by the NIH's Eating at America's Table questionnaire (All Day) and the Dietary Screener Questionnaires baseline, post intervention (9 months after baseline) This is a 6-item questionnaire. The parent responds the number of servings their child consumed during the time period. Servings are calculated based on the servings per day.
Child diastolic blood pressure post intervention (9 months after baseline) Child's diastolic blood pressure will be obtained with an automatic cuff. This will be measure during biometric events.
Number of servings consumed by the parent as assessed by the Adapted Health of Houston Survey (HHS) on processed food/drinks 4-items, and fruit and vegetable intake 2 items. baseline, post intervention (9 months after baseline) This is a 6-item questionnaire. The parent responds the number of servings they consumed during the time period. Servings are calculated based on the servings per day.
Child systolic blood pressure Post intervention (9 months after baseline) Child's systolic blood pressure will be obtained with an automatic cuff. This will be measure during biometric events.
Change in home access/availability of fruits and vegetables as assessed by the Nutrition security measures questionnaire baseline, post intervention (9 months after baseline) Nutrition security measures assess factors associated with a household's ability to obtain foods that meet their nutritional and health needs. Household Food Insecurity will be measured using 2-item Hunger Vital Sign food security survey and 4-items adapted from the Center for Nutrition and Health Impact, for a total of 6-items.
The items are scored from 0 (if the participant selects "Always") to 4 (if the participant selects "Never") and the measure's score is the mean of the responses. The higher the participant's score, the greater degree of the household nutrition security.
