BRÄNSLE: Mat, rolig, fräsch, familj för hälsosam kost och tillväxt för barn i lågstadiet. (FUEL)

• Family tip sheets sent via mobile text at the start of the program and then every 3 weeks, to a total of 6 mobile text messages

• Weeks 1-4 (4 weeks):

  i. Welcome package mailed in the first week of the program ii. Weekly: one 10-lbs box of produce iii. Recipes accompanying each box (sample recipe card attached to submission) iv. Bi-Weekly: Grocery store gift cards (2x USD 20, to a total of USD 40)

• Weeks 5-19 (total of 10 weeks over the 19-week study timeline):

  i. An optional online form ("goal sheet") is sent to the parent/caregiver every other week (total 5) with questions about trying new FV items to be submitted in the next 7 days. As an incentive, a USD 10 gift card is sent to those who complete it (a potential total of USD 50).

ii. Week 11: an extra USD 20 gift card in the week after a school holiday to re-engage participants due to the school-year break.

1. The whole BGCAA's after-school program runs for 3h, Mon-Fri for the school year across all sites where the organization offers the program. All children enrolled are expected to attend a minimum of 2x/week.
2. In the BGCAA's after-school program, children participate in active recreational time (approx. 60 min, offered 1x/week at a minimum) which is a mixture of free play, structured physical activity games, and/or sports activities (including soccer, football, and basketball).
3. Uniquely to sites participating in the study, BGCAA's staff will deliver selected CATCH (Coordinated Approach to Child Health) curriculum components in blocks of 45-60 min, 2x/week, as part of the after-school program. The curriculum will focus on healthy eating education and physical activity designed for elementary school-aged children. More information on CATCH at https://catch.org/ (accessed 8/11/2023)

This study will use the section of the TX SPAN data collection instrument related to food choices via structured interview (English or Spanish). 32 questions reference specific marker foods or food groups asking the number of times each food group was consumed on the previous day (analogous to a 24h recall), with responses 0 times, 1 time, 2 times or 3 or more times. Total FV variety will be measured by summing the items that ask about fruit and vegetable varieties (excluding juice).

More on the TX SPAN can be found at <go.uth.edu/SPAN>.

As described in 2015 Ranjit et al. SPAN Healthy Eating Index (SHEI) is a composite measure comprising both healthy and unhealthy items from diet measures available in the TX SPAN.

Healthy score is the sum of previous day consumption of baked or grilled (not fried) meats, milk, yogurt, brown rice, brown pasta, a variety of vegetable types, fruits (not fruit juice), and beans.

Unhealthy score is the sum of consumption of fried meat, red meat, sugar-sweetened beverages, salty fried snacks, and a variety of dessert items. These are reverse coded, so that the lowest frequency represented the healthiest eating practice.

These two sums are combined into the single composite SHEI and rescaled from 0-100, where higher scores mean healthier eating practices.

The DSQ FV module has 10 items that capture frequency of consumption of fruits and vegetables and their sources (such as vegetables in recipes) in the past 30 days. It does not require participants to report serving size. Responses are converted to daily cup equivalent estimates.

Twice during the program, all children in the after-school program will participate in an interactive activity during a field day where BGCAA staff (blinded to the study arm allocation) measures the children's weight, height and how high they can jump. Because body weight may be a sensitive issue to some children and/or their families, it was proposed to embed it in the daily after-school activities, minimizing the focus on direct and open measurement of weight.

First, height will be measured using a stadiometer against the wall before the activity. Then, the child will stand on a mat with an integrated scale that will measure their weight. Finally, the children will write their name on an athletic tape and/or post-it notes and jump to stick it to a wall.

Self-reported measure assessing the impact of health on an individual's everyday life, often used as a quality of life measure. Two summary scores are reported: 1) a mental component score (MCS-12) and 2) a physical component score (PCS-12). The United States population average PCS-12 is 50 points with standard deviation of 10 points.

SDQ is a brief psychological assessment and behavioral screening tool for 2-17 year-olds (Goodman, 1997), reported by their parents/guardians in the study. 25 items are divided between 5 scales: 1) emotional symptoms (5 items); 2) conduct problems (5 items); 3) hyperactivity/inattention (5 items); 4) peer relationship problems (5 items); 5) prosocial behavior (5 items), with the timeframe of past 6 months. Scores in the sections 1 to 4 are added to generate a total difficulties score (20 items). Higher scores indicate greater difficulties (poorer mental health status).

Questions are posed to the guardian. Two items assess 1) how many days in the past week the child was physically active for at least 60 min. and 2) played outdoors for at least 30 min. outside of school hours. The other 5 items assess attitude and usual engagement in physical activity. The demographics survey at baseline will ask whether the child has limited physical ability to engage in activities.
