Participant Flow
We recruited from Head Start centers in three different regions: 1) Central Valley of Washington 2) Seattle, Washington 3) Houston, Texas. Research staff recruited a total of N= 22 schools and N=201 parent-child dyads to participate in the study. But, children were the focus of the intervention study outcomes. We report results pertaining to the children only. Head Start organizations in the three regions found centers for recruitment and those centers assisted in publicizing the trial.
Prior to randomization at Time 1, all assessments and surveys measuring mediating, moderating and outcome variables as well as covariates were assessed immediately pre-intervention at Time 1. Prior to randomization, we enrolled and consented 215 participants. Of those 215, 14 did not complete baseline assessments and/or were lost to follow -- these 14 participants were not randomized. Following Time 1, randomization occurred on a unit (Head Start school) level.

Screen Time Reduction Curriculum
Fit5Kids curriculum, weekly parent newsletters, in-person (or by telephone) goal setting on their child's screen time, a lending library of resources (books, games, arts/crafts, etc), and text messages on screen time parenting practices.
Screen Time Reduction Curriculum: Fit5Kids classroom curriculum, weekly parent newsletters, in-person (or by telephone) goal setting on their child's screen time, a lending library of resources (books, games, arts/crafts, etc), and text messages on screen time parenting practices offered over 7-8 weeks in the Fall semester. The classroom component will be taught by bilingual (English/Spanish) research staff interventionists. Parent newsletters, goal setting, and text messages will be offered in English and Spanish per parent preference. There will also be two "booster" weeks of classroom activities, daily parent newsletters, goal setting, and daily text messages on screen time parenting practices offered during the booster weeks in the Spring semester. The lending library of resources for parents/children will be available throughout the entire school year.

SECONDARY outcome
Timeframe: Week 1-2, Week 11-12, and Week 34-36Measured Height and Weight Pre-intervention vs Post-intervention. Body Mass Index (BMI) Z-score, is the child's calculated standard deviation from the CDC's population reference for child's sex and age. The formula is: Z-score = ((BMI / M)L - 1) / (L × S) where BMI is body mass index, M is median, L is the transformation for normality, and S is the coefficient of variations. A Z-score of 0 represents the mean for the CDC's reference population. Z-scores above the mean generally represent a worse outcome. A Z-score of 1.645 is the 95th percentile, which is considered the threshold for obesity.

Timeframe: Week 1-2, Week 11-12, and Week 34-36Dietary Intake Pre-intervention vs Post-intervention, measured by Block Kids Food Screener (more details below) Block Food Screeners for Ages 2-17 2007: These screeners are designed to assess children's intake by food group, with outcomes measured in number of servings. The version the investigative team will use for this study is about food eaten "last week." The focus of this tool is on intake of fruit and fruit juices, vegetables, potatoes (including French fries), whole grains, meat/poultry/fish, dairy, legumes, saturated fat, "added sugars" (in sweetened cereals, soft drinks, and sweets), glycemic load and glycemic index. A positive outcome would be to observe an increase in intake of fruit and vegetables, and reduced intake of saturated fats and added sugars.

Skin carotenoids are measured using Raman spectroscopy, which returned results in units of Raman counts from 0 to 70,000. Greater Raman counts indicate greater skin carotenoids and greater fruit/vegetable intake.

SECONDARY outcome
Timeframe: Week 1-2, Week 11-12, and Week 34-36Dietary Intake Pre-intervention vs Post-intervention, measured by Block Kids Food Screener (more details below) Block Food Screeners for Ages 2-17 2007: These screeners are designed to assess children's intake by food group, with outcomes measured in number of servings. The version the investigative team will use for this study is about food eaten "last week." The focus of this tool is on intake of fruit and fruit juices, vegetables, potatoes (including French fries), whole grains, meat/poultry/fish, dairy, legumes, saturated fat, "added sugars" (in sweetened cereals, soft drinks, and sweets), glycemic load and glycemic index. A positive outcome would be to observe an increase in intake of fruit and vegetables, and reduced intake of saturated fats and added sugars.

Screen Time Reduction Curriculum
n=92 Participants
Fit5Kids curriculum, weekly parent newsletters, in-person (or by telephone) goal setting on their child's screen time, a lending library of resources (books, games, arts/crafts, etc), and text messages on screen time parenting practices.
Screen Time Reduction Curriculum: Fit5Kids classroom curriculum, weekly parent newsletters, in-person (or by telephone) goal setting on their child's screen time, a lending library of resources (books, games, arts/crafts, etc), and text messages on screen time parenting practices offered over 7-8 weeks in the Fall semester. The classroom component will be taught by bilingual (English/Spanish) research staff interventionists. Parent newsletters, goal setting, and text messages will be offered in English and Spanish per parent preference. There will also be two "booster" weeks of classroom activities, daily parent newsletters, goal setting, and daily text messages on screen time parenting practices offered during the booster weeks in the Spring semester. The lending library of resources for parents/children will be available throughout the entire school year.
