“…TX Sprouts targeted 3rd to 5th grade students and their parents from 16 elementary schools in the Greater Austin area. Methods for the clinical trial are published elsewhere [ 24 ]. Briefly, schools were randomized into one of two groups, namely TX Sprouts intervention ( n = 8 schools) and delayed intervention ( n = 8 schools), and data collection occurred in three waves between 2016 and 2019.…”

Knowing which barriers to buying and preparing/cooking vegetables at home are linked with the home availability of vegetables and how food-security status impacts this relationship will facilitate the tailoring of future public health interventions. Baseline data were used from an elementary-school-based intervention. Data on household food-security status, availability of vegetables at home, and barriers to buying and preparing/cooking vegetables were collected from 1942 parents. Differences between food-secure and food-insecure households were examined for barriers to buying and preparing/cooking vegetables. Mixed-effects linear regression was used to estimate the associations between barriers to buying and preparing/cooking vegetables and food-security status on the home availability of vegetables. Food insecurity was reported in 27% of households. Food-insecure households were significantly more likely to report barriers to buying and preparing/cooking vegetables. The barriers to purchasing/cooking vegetables score was associated with a decrease in the home availability of vegetables score (β = −0.77; 95% CI: −0.88, −0.65; p < 0.001). Compared to food-secure households, food-insecure households were 15% less likely to have home vegetable availability (β = −1.18; 95% CI: −1.45, −0.92; p < 0.001). Although home availability of vegetables does not guarantee consumption, this study identified specific barriers that were associated with availability that can be targeted in future interventions seeking to improve vegetable consumption in the homes of low-income families.

“…Schools included in the study had to meet the following inclusion criteria: 1 ) high proportion of Hispanic children (>50%); 2 ) high proportion of children participating in the free and reduced lunch program (>50%); 3 ) location within 97 km (60 miles) of The University of Texas at Austin; and 4 ) no existing garden or gardening program. Full methods of the TX Sprouts intervention are published elsewhere ( 23 ). The trial is registered at clinicaltrials.gov (NCT02668744).…”

Background A key goal of the Dietary Guidelines for Americans 2015–2020 is to reduce added sugar intake by increasing public knowledge about added sugars. However, research has not shown if knowledge of added sugar recommendations is associated with intake. Objective To determine the relationship between parent and child knowledge of added sugar recommendations on added sugar intake in primarily low-income and Hispanic 3rd to 5th grade students. Methods Analysis examined baseline, cross-sectional data from TX Sprouts, a 1-year cooking, gardening, and nutrition clustered, randomized controlled trial. Participants were 685 parent-child dyads from 16 elementary schools in the greater Austin area. Parents and children completed a survey to assess knowledge of added sugar recommendations. Children completed two, 24-hour dietary recalls to assess average intake of added sugars. Mixed effects linear regression models were used to estimate associations between child and parent knowledge of added sugar recommendations and average total added sugar intake. Results Children who correctly identified the added sugar recommendation consumed lower amounts of added sugar compared to children who did not correctly identify the recommendation (34.8 ± 2.7 vs. 41.0 ± 2.5 grams, P = 0.003), after adjusting for sociodemographic characteristics. Parent knowledge of added sugar recommendations was not associated with child intake. Conclusions Child knowledge of added sugar recommendations was associated with lower intake of added sugars. Findings suggest that child nutrition education should focus on increasing knowledge of national recommendations. Future research should investigate a causal relationship between added sugar knowledge and intake in elementary-aged children.

Background Although school garden programs have been shown to improve dietary behaviors, there has not been a cluster-randomized controlled trial (RCT) conducted to examine the effects of school garden programs on obesity or other health outcomes. The goal of this study was to evaluate the effects of a one-year school-based gardening, nutrition, and cooking intervention (called Texas Sprouts) on dietary intake, obesity outcomes, and blood pressure in elementary school children. Methods This study was a school-based cluster RCT with 16 elementary schools that were randomly assigned to either the Texas Sprouts intervention (n = 8 schools) or to control (delayed intervention, n = 8 schools). The intervention was one school year long (9 months) and consisted of: a) Garden Leadership Committee formation; b) a 0.25-acre outdoor teaching garden; c) 18 student gardening, nutrition, and cooking lessons taught by trained educators throughout the school-year; and d) nine monthly parent lessons. The delayed intervention was implemented the following academic year and received the same protocol as the intervention arm. Child outcomes measured were anthropometrics (i.e., BMI parameters, waist circumference, and body fat percentage via bioelectrical impedance), blood pressure, and dietary intake (i.e., vegetable, fruit, and sugar sweetened beverages) via survey. Data were analyzed with complete cases and with imputations at random. Generalized weighted linear mixed models were used to test the intervention effects and to account for clustering effect of sampling by school. Results A total of 3135 children were enrolled in the study (intervention n = 1412, 45%). Average age was 9.2 years, 64% Hispanic, 47% male, and 69% eligible for free and reduced lunch. The intervention compared to control resulted in increased vegetable intake (+ 0.48 vs. + 0.04 frequency/day, p = 0.02). There were no effects of the intervention compared to control on fruit intake, sugar sweetened beverages, any of the obesity measures or blood pressure. Conclusion While this school-based gardening, nutrition, and cooking program did not reduce obesity markers or blood pressure, it did result in increased vegetable intake. It is possible that a longer and more sustained effect of increased vegetable intake is needed to lead to reductions in obesity markers and blood pressure. Clinical trials number NCT02668744.
