School-based gardening, cooking and nutrition intervention increased vegetable intake but did not reduce BMI: Texas sprouts - a cluster randomized controlled trial.

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 .

Ethnicity/race, parent educational attainment, and obesity associated with prediabetes in children.

BACKGROUND/OBJECTIVES: Obesity and other predictors of type 2 diabetes disproportionally affect Hispanic and Black children in the US compared to non-Hispanic White (NHW) children. Yet, the prevalence of prediabetes in children remains unestablished, and guidelines for screening young children are lacking. This study examined the relationships between demographic factors and prediabetes in vulnerable youth in central Texas. SUBJECTS/METHODS: This is a cross-sectional analysis of baseline data from 976 3rd-5th graders (7-12 years) who participated in TX Sprouts, a school-based gardening, nutrition, and cooking trial in 16 elementary schools serving mainly children from minority backgrounds and lower-income households. Measures collected included age, sex, ethnicity, free/reduced-priced school lunch (FRL) status, parent educational attainment (questionnaires), BMI from height (stadiometer) and weight (TANITA scale), and prediabetes status from fasting plasma glucose (FPG) and HbA1c. Regressions examined cross-sectional associations between demographics and FPG, HbA1c, and prediabetes. RESULTS: Children were 47% male, 67% Hispanic, and 10% Black, with a mean age of 9.3 years; 71% received FRL, 50% had overweight/obesity, and 26% had prediabetes. Prediabetes rates were 2.8 and 4.8 times higher in Hispanic and Black children compared to NHW children, respectively (p ≤ 0.001), and 1.5 times higher in children with obesity versus normal BMI (p = 0.02). Children of parents with only an 8th-grade education, some high school education, or a high school degree had 3.1, 2.7, and 2.2 times higher odds of having prediabetes compared to children of college graduates, respectively (p ≤ 0.004). Analyses with FPG and HbA1c yielded similar results. CONCLUSION: These findings suggest a potential need for earlier screening, more comprehensive testing guidelines, and prevention programs tailored toward minority children, children with obesity, and children of parents with low educational attainment. Future research should explore this finding in a larger, nationally representative sample.

Dietary Psychosocial Mediators of Vegetable Intake in Schoolchildren From Low-Income and Racial and Ethnic Minority US Families: Findings From the Texas Sprouts Intervention.

BACKGROUND: Numerous school-based interventions have used cooking and gardening approaches to improve dietary intake; however, research is limited on the mediation effect of dietary psychosocial factors on the link between the intervention and increased vegetable intake, particularly in children from low-income and racial and ethnic minority US families. OBJECTIVE: Our aim was to examine the effects of the Texas Sprouts intervention on dietary psychosocial factors related to intake of vegetables, and whether these psychosocial factors mediate the link between the intervention and increased intake of vegetables in schoolchildren from low-income and racial and ethnic minority US families. DESIGN: This was an analysis of data on secondary outcomes from the Texas Sprouts program, a 1-year school-based gardening, nutrition, and cooking cluster randomized controlled trial consisting of elementary schools that were randomly assigned to either the Texas Sprouts intervention or to control. PARTICIPANTS/SETTING: Participants were 2,414 third- through fifth-grade students from low-income and racial and ethnic minority US families from 16 schools (8 intervention and 8 control) in Austin, TX. INTERVENTION: The intervention group received eighteen 60-minute gardening, nutrition, and cooking student lessons in an outdoor teaching garden and 9 monthly parent lessons throughout the academic year. MAIN OUTCOME MEASURES: Child psychosocial and dietary measures were collected at baseline and post intervention via validated questionnaires. STATISTICAL ANALYSES PERFORMED: Generalized linear mixed models assessed the intervention effects on dietary psychosocial factors. Mediation analyses examined whether these psychosocial factors mediated the link between the intervention and increased child vegetable intake. RESULTS: Children in Texas Sprouts, compared with controls, showed significant increases in the mean scores of gardening attitudes, cooking self-efficacy, gardening self-efficacy, nutrition and gardening knowledge, and preferences for fruit and vegetables (all, P < .001). Each of the dietary psychosocial factors mediated the association between the Texas Sprouts intervention and child vegetable intake. CONCLUSIONS: Besides targeting dietary behaviors, future school-based interventions should also focus on understanding the mechanisms through which teaching children to cook and garden influence dietary psychosocial factors as mediators of change in healthy eating behaviors.

Effects of a School-Based Garden Program on Academic Performance: A Cluster Randomized Controlled Trial.

BACKGROUND: School gardening programs have consistently been found to improve dietary behaviors in children. Although several quasi-experimental studies have also reported that school gardens can enhance academic performance, to date, no randomized controlled trial has been conducted to substantiate this. OBJECTIVE: The objective of the study was to examine the effects of Texas Sprouts (TX Sprouts), a gardening, nutrition, and cooking program vs control on academic performance in primarily low-income, Hispanic children. DESIGN: This is a secondary analysis of the grade-level academic scores from schools that participated in the TX Sprouts program, a school-based cluster randomized controlled trial, consisting of 16 elementary schools that were randomly assigned to either the TX Sprouts intervention (n = 8 schools) or control (delayed intervention; n = 8 schools). PARTICIPANTS/SETTING: Analysis included 16 schools with students in fourth and fifth grade in Austin, TX from 2016 to 2019 that had a majority Hispanic population and a majority of children participating in the free and reduced lunch program. INTERVENTION: The intervention consisted of 18 one-hour gardening, nutrition, and cooking lessons taught in an outdoor teaching garden by trained educators throughout the academic year. MAIN OUTCOME MEASURES: Texas Education Agency grade-level data for the State of Texas Assessments of Academic Readiness were obtained via the Texas Education Agency website for the corresponding year of the intervention or control condition. STATISTICAL ANALYSIS PERFORMED: Repeated measures general linear models with pre- and post-intervention State of Texas Assessments of Academic Readiness scores as the dependent variable were run, adjusting for the percent of free and reduced lunch and school district as covariates. RESULTS: Schools that received the TX Sprouts intervention had a 6.5-percentage-point increase in fourth-grade reading State of Texas Assessments of Academic Readiness scores compared with control schools (P = .047). There were no significant differences in reading scores for fifth grade students or math scores for either fourth- or fifth-grade students between groups. CONCLUSIONS: Study findings provide evidence that school gardening programs may have some modest effects on academic achievement.

Comparison of School vs Home Breakfast Consumption with Cardiometabolic and Dietary Parameters in Low-Income, Multiracial/Ethnic Elementary School-Aged Children.

BACKGROUND: Breakfast consumption is often associated with improving cardiometabolic parameters and diet quality. However, literature evaluating breakfast consumption with these outcomes between the school and home environments is limited. OBJECTIVE: This study examined relationships between breakfast consumption locations (school vs home) and cardiometabolic parameters, breakfast dietary intake, and daily dietary intake. DESIGN: This cross-sectional study used baseline data from TX Sprouts, a 1-year school-based gardening, nutrition, and cooking cluster-randomized trial, implemented in 16 elementary schools in Austin, TX, during 2016 to 2019. PARTICIPANTS/SETTING: Analyses included 383 low-income, multiracial/ethnic elementary school-aged children (mean age = 9.2 years; 60.6% Hispanic; 70.5% free/reduced lunch; 58.5% home breakfast consumers). MAIN OUTCOME MEASURES: Cardiometabolic parameters were obtained via fasting blood draws, and dietary intake was assessed using one 24-hour dietary recall conducted on a random, unannounced weekday. Cardiometabolic and dietary parameters (ie, energy intake, macronutrients, and food group servings) for breakfast and for the day were evaluated. STATISTICAL ANALYSES PERFORMED: Multivariate analysis of covariance was performed to examine cardiometabolic parameters and dietary intake between school and home breakfasts. RESULTS: School breakfast consumers (SBC) had lower fasting triglyceride levels than home breakfast consumers (HBC) (89.0 mg/dL vs 95.7 mg/dL; P = 0.03) (to convert to mmol/L, multiply by 0.0113). SBC had lower total fat for the day (P = 0.02) and lower total and saturated fat, sodium, and refined grains at breakfast (P ≤ 0.01) than HBC. However, SBC had lower protein at breakfast (P = 0.01) and higher carbohydrates, total sugar, and added sugar for the day and at breakfast (P ≤ 0.03) than HBC. CONCLUSIONS: SBC compared with HBC had lower fat intake, which may have contributed to the lower triglyceride level observed in SBC, but also had lower protein intake at breakfast and higher added sugar intake for the day and at breakfast. These results suggest dietary intake differed between HBC and SBC; that is, the home and school environments, but more research is needed to evaluate if such differences are due to School Breakfast Program guidelines.

Distinct racial and ethnic metabolic syndrome characteristics: A comparative assessment in low-income children 7-10 years of age.

BACKGROUND: Pediatric MetS prevalence varies due to lack of consensus on evaluative criteria and associated thresholds, with most not recommending a diagnosis <10 years. However, MetS risk components are becoming evident earlier in life and affect races and ethnicities disproportionately. OBJECTIVES: To compare the prevalence of MetS based on existing definitions and elucidate racial- and ethnic-specific characteristics associated with MetS prevalence. METHODS: The baseline and follow-up samples included 900 and 557 children 7-10 years, respectively. Waist circumference, BMI percentile, blood pressure, fasting plasma glucose (FPG), insulin, triglycerides, and high-density lipoprotein cholesterol (HDL-C) were measured. Agreement between MetS definitions was quantified via kappa statistics. MetS and risk factor prevalence and the predictability of metabolic parameters on MetS eight months later was evaluated via logistic regression. McFadden pseudo-R2 was reported as a measure of predictive ability, and the Akaike information criterion evaluated fit of each model. RESULTS: The baseline sample was 55.0% male and 71.6% Hispanic, followed by non-Hispanic White (NHW) (17.3%) and non-Hispanic Black (NHB) (11.1%), with an average age of 9.2 years. MetS prevalence ranged from 7.6% to 21.4%, highest in Hispanic (9.0%-24.0%) and lowest in NHB children (4.0%-14.0%). Highest agreement was between Ford et al. and Cook et al. definitions (K = 0.88) and lowest agreements were consistently with the International Diabetes Federation criteria (K ≤ 0.57). Compared to NHW children, Hispanic children had higher odds for MetS (OR: 1.7; p = 0.03) and waist circumference, HDL-C, and FPG risk factors (p < 0.05), while NHB children had higher odds for the FPG risk factor (p ≤ 0.007) and lower odds for the plasma triglycerides risk factor (p = 0.002), across multiple MetS definitions. In longitudinal analyses, HDL-C was the strongest independent predictor of MetS in Hispanic and NHW children (p < 0.001 and p < 0.01, respectively), while plasma triglycerides was the strongest independent predictor of MetS in NHB children (p < 0.05). CONCLUSIONS: MetS prevalence was high in children ≤10 years, and proposed criteria are susceptible to racial and ethnic bias, diagnosing some populations more than other populations with high cardiovascular risk. Earlier preventative measures should be imposed in clinical settings, accounting for racial and ethnic differences, to mitigate disease onset.

Impact of a School-Based Gardening, Cooking, Nutrition Intervention on Diet Intake and Quality: The TX Sprouts Randomized Controlled Trial.

School gardens have become common school-based health promotion strategies to enhance dietary behaviors in the United States. The goal of this study was to examine the effects of TX Sprouts, a one-year school-based gardening, cooking, and nutrition cluster randomized controlled trial, on students' dietary intake and quality. Eight schools were randomly assigned to the TX Sprouts intervention and eight schools to control (i.e., delayed intervention) over three years (2016-2019). The intervention arm received: formation and training of Garden Leadership Committees; a 0.25-acre outdoor teaching garden; 18 student lessons including gardening, nutrition, and cooking activities, taught weekly in the teaching garden during school hours; and nine parent lessons, taught monthly. Dietary intake data via two 24 h dietary recalls (24 hDR) were collected on a random subsample (n = 468). Dietary quality was calculated using the Healthy Eating Index 2015 (HEI-2015). The intervention group compared to control resulted in a modest increase in protein intake as a percentage of total energy (0.4% vs. -0.3%, p = 0.021) and in HEI-2015 total vegetables component scores (+4% vs. -2%, p = 0.003). When stratified by ethnicity/race, non-Hispanic children had a significant increase in HEI-2015 total vegetable scores in the intervention group compared to the control group (+4% vs. -8%, p = 0.026). Both the intervention and control groups increased added sugar intake; however, to a lesser extent within the intervention group (0.3 vs. 2.6 g/day, p = 0.050). School-based gardening, cooking, and nutrition interventions can result in significant improvements in dietary intake. Further research on ways to scale and sustain nutrition education programs in schools is warranted. The trial is registered at ClinicalTrials.gov (NCT02668744).

Breakfast Consumption in Low-Income Hispanic Elementary School-Aged Children: Associations with Anthropometric, Metabolic, and Dietary Parameters.

Breakfast consumption is associated with lower obesity prevalence and cardiometabolic risk and higher dietary quality (DQ) in children. Low-income, Hispanic populations are disproportionately affected by obesity and cardiometabolic risks. This study examined the relationship between breakfast consumption groups (BCG) on anthropometric, metabolic, and dietary parameters in predominately low-income, Hispanic children from 16 Texas schools. Cross-sectional data were from TX Sprouts, a school-based gardening, nutrition, and cooking randomized controlled trial. Anthropometric measurements included height, weight, body mass index, body fat percent via bioelectrical impedance, waist circumference, and blood pressure. Metabolic parameters included fasting plasma glucose, insulin, glycated hemoglobin, cholesterol, and triglycerides. DQ and BCG were assessed via two 24-h dietary recalls. Multivariate multiple regression examined relationships between BCG and anthropometric, metabolic, and dietary parameters. This study included 671 students (mean age 9 years, 58% Hispanic, 54% female, 66% free/reduced lunch, 17% breakfast skippers). No relationships were observed between BCG and anthropometric or metabolic parameters. BCG had higher DQ; higher daily protein, total sugar, and added sugar intake; and lower daily fat intake. Skipping breakfast was associated with lower DQ; higher daily fat intake; and lower daily protein intake. Longitudinal research examining breakfast quality on cardiometabolic outcomes in low-income, Hispanic children is warranted.

Associations between Child and Parent Knowledge of Added Sugar Recommendations and Added Sugar Intake in Multiethnic Elementary-Aged Children.

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. OBJECTIVES: To determine the relation between parent and child knowledge of added sugar recommendations with added sugar intake in primarily low-income and Hispanic third- to fifth-grade students. METHODS: Analysis examined baseline, cross-sectional data from TX Sprouts, a 1-y 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-h 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 with children who did not correctly identify the recommendation (34.8 ± 2.7 compared with 41.0 ± 2.5 g; 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 relation between added sugar knowledge and intake in elementary-aged children.

The Association Between Child Cooking Involvement in Food Preparation and Fruit and Vegetable Intake in a Hispanic Youth Population.

BACKGROUND: Cooking interventions have been linked to reductions in obesity and improvements in dietary intake in children. OBJECTIVE: To assess whether child cooking involvement (CCI) was associated with fruit intake (FI), vegetable intake (VI), vegetable preference (VP), and vegetable exposure (VE) in children participating in the Texas, Grow! Eat! Go! (TGEG) randomized controlled trial. METHODS: Baseline data from TGEG included 1231 3rd grade students and their parents. Conducted in 28 low-income, primarily Hispanic schools across Texas, TGEG schools were assigned to: 1) Coordinated School Health (CSH) only (control group), 2) CSH plus gardening and nutrition intervention (Learn, Grow, Eat & Go! or LGEG group), 3) CSH plus physical activity intervention (Walk Across Texas or WAT group), and 4) CSH plus LGEG plus WAT (combined group). Height, weight, dietary intake, VE, VP, and CCI were collected at baseline and postintervention. Linear regressions were used to assess the relation between baseline CCI and fruit and vegetable (FV) intake, VE, and VP. A priori covariates included age, sex, race/ethnicity, and TGEG treatment group. RESULTS: Children who were always involved in family cooking had higher VP and VE when compared with children who were never involved in family cooking (ß = 3.26; 95% CI: 1.67, 4.86; P < 0.01 and ß = 2.26; 95% CI: 0.67, 3.85; P < 0.01, respectively). Both VI and FI were higher for children who were always involved in family cooking compared with children who never cooked with their family (ß = 2.45; 95% CI: 1.47, 3.44; P < 0.01 and ß = 0.93; 95% CI: 0.48, 1.39; P < 0.01, respectively). VI and fruit consumption were higher for children who reported being sometimes involved in family cooking compared with children who were never involved in family cooking, (ß = 1.47; 95% CI: 0.51, 2.42; P < 0.01, and ß = 0.64; 95% CI: 0.20, 1.08; P < 0.01, respectively). CONCLUSIONS: Results show a positive relation between family cooking and FV intake and preference in high-risk, minority children.

Barriers to Preparing and Cooking Vegetables Are Associated with Decreased Home Availability of Vegetables in Low-Income Households.

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 (ß = -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 (ß = -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.

Child Compared with Parent Perceptions of Child-Level Food Security.

BACKGROUND: There is a need to directly and accurately conceptualize and measure food insecurity in children as part of surveillance and public health efforts. OBJECTIVE: The aim of this study was to compare parent and child perceptions of child-level food security status via questionnaires within a large, ethnically diverse population. METHODS: Cross-sectional baseline data from a cluster-randomized controlled trial involving primarily low-income, Hispanic third- to fifth-grade students and their parents were used for analysis. The sample consisted of 2408 dyadic (parent and child) pairs. Parents completed the 8-item child-referenced Household Food Security Survey Module and their responses were compared with an adaption of the 5-item Child Food Security Assessment completed by their child. Levels of association between child and parent perceptions within dyads were calculated using Goodman and Kruskal's γ statistic. A mixed-effects binomial logistic regression model was used to model discordance as a function of child, parent, and household sociodemographic characteristics. RESULTS: The child sample was 53% girls, mean age of 9 y, and 63% were Hispanic. The parent sample was 86% women and 65% Hispanic. Child and parent perceptions of child-level food security agreed only 21.7% of the time. There was a weak positive association between child and parent perceptions of child-level food security (γ = 0.162, P < 0.001). Children perceived themselves as less food secure than their parents' perception 70.1% of the time. Household receipt of Supplemental Nutrition Assistance Program benefits was associated with greater odds of discordant food security perceptions, whereas female children, older children, and parents not working were characteristics associated with lower odds of discordant perceptions. CONCLUSIONS: Results, in combination with the existing literature, suggest that parent perceptions of child-level food insecurity may underestimate child-level food insecurity experiences. Inaccurate estimations or underestimations of the true prevalence of child-level food insecurity could be detrimental to maternal and child health efforts. This trial was registered at clinicaltrials.gov as NCT02668744.

Child-Report of Food Insecurity Is Associated with Diet Quality in Children.

Food insecurity (FI) is adversely associated with physical and mental wellbeing in children. The mechanism underlying this association is assumed to be dietary intake; however, evidence has been mixed. This study examined the relationship between self-reported FI and dietary quality among low-income children. Cross-sectional data were used from TX Sprouts, a school-based cooking, gardening, and nutrition intervention. A sample of 598 children completed two 24-h dietary recalls and a questionnaire including an adapted version of the 5-item Child Food Security Assessment (CFSA). Food security was categorized as food secure or FI based on summed CFSA scores. Dietary quality was assessed using the Health Eating Index-2015 (HEI-2015). Mixed effects linear regression models examined associations between FI and dietary quality. Children were 64% Hispanic, 55% female, and were 9.2 years old on average. Adjusting for sociodemographic characteristics, BMI percentile, and energy intake, FI was associated with lower HEI-2015 total scores (ß = -3.17; 95% CI = -5.28, -1.06; p = 0.003). Compared to food secure children, FI children had lower greens and beans (2.3 vs. 1.9, p = 0.016), seafood and plant protein (2.0 vs. 1.6, p = 0.006), and added sugar (7.4 vs. 8.0, p = 0.002) component scores. Interventions targeting low-income and FI children should investigate ways to improve dietary quality.

Association of breastfeeding and early exposure to sugar-sweetened beverages with obesity prevalence in offspring born to mothers with and without gestational diabetes mellitus.

BACKGROUND: The relationship of gestational diabetes mellitus (GDM), exclusive breastfeeding (EBF), and sugar-sweetened beverages (SSBs) on obesity prevalence in children has rarely been evaluated. OBJECTIVE: This study examined the association of GDM status, EBF, and SSB with obesity prevalence in children (1-5 y). METHODS: Data are from the 2014 Los Angeles County WIC Survey, which included 3707 mothers and their children (1-5 y). RESULTS: Compared with GDM offspring who were not EBF, GDM offspring who were EBF had lower odds of obesity, as did non-GDM offspring who were and were not EBF. Compared with GDM offspring with high-concurrent SSB intake (>3 servings/d) and no EBF, GDM offspring with high SSB intake and EBF did not have lower odds of obesity, whereas those with GDM, low SSB (≤1 serving/d), and EBF had lower odds of obesity. Using non-GDM, EBF, and low SSB as referent, non-GDM offspring who were not EBF, with either high or low SSB, had approximately a fourfold increase in odds of obesity. CONCLUSIONS: In GDM offspring, EBF is only associated with lower obesity levels if later SSB intake is also low, whereas EBF is protective against obesity in non-GDM offspring regardless of high or low later SSBs intake.

Diet Quality Is an Indicator of Disease Risk Factors in Hispanic College Freshmen.

BACKGROUND: No studies have assessed the relationship between diet quality, using the Healthy Eating Index (HEI), and adiposity, physical activity, and metabolic disease risk factors in a Hispanic college population. OBJECTIVE: To assess associations between diet quality and adiposity, metabolic health, and physical activity levels in a Hispanic college freshman population. DESIGN: This was a cross-sectional study. Measurements were obtained during a 4-hour in-person visit and included demographic information via questionnaire, height, weight, waist circumference, body mass index, body fat via BodPod, hepatic fat, visceral adipose tissue (VAT) and subcutaneous adipose tissue via magnetic resonance imaging, glucose, insulin, homeostatic model assessment of insulin resistance (HOMA-IR), and lipids via blood draw from fasting subjects, physical activity (ie, step counts per day and time spent in different intensity levels) via 7-day accelerometry, and dietary intake via three to four 24-hour dietary recalls. Dietary quality was calculated using the HEI-2015. PARTICIPANTS/SETTING: Hispanic college freshmen (n=92), 18 to 19 years, 49% male, who were enrolled at University of Texas at Austin from 2014 to 2015. MAIN OUTCOME MEASURES: Main outcome measures were diet quality and adiposity, metabolic health, and physical activity levels. STATISTICAL ANALYSES PERFORMED: Linear regressions determined if dietary quality is related to adiposity, metabolic, and physical activity outcomes. A priori covariates included sex, body fat, and body mass index percentile (for metabolic models), and moderate and vigorous physical activity (MVPA, for adiposity and metabolic models). RESULTS: The average HEI-2015 total score was 54.9±13.4. A 1-point increase in HEI score was associated with 1.5 mL lower VAT (P=0.013); 8 minutes per day higher light activity (P=0.008), and 107 more step counts per day (P=0.002); and 0.10 µg/mL lower insulin (P=0.046) and 0.5 U lower HOMA-IR (P<0.001). CONCLUSION: Results suggest that small improvements in diet quality may be positively associated with a reduction in metabolic disease risk, during a critical time period in a young person's life.

Association of breastfeeding and gestational diabetes mellitus with the prevalence of prediabetes and the metabolic syndrome in offspring of Hispanic mothers.

BACKGROUND: The effects of breastfeeding (BF) on metabolic syndrome (MetS) and diabetes mellitus in children exposed to gestational diabetes mellitus (GDM) in utero have rarely been evaluated. OBJECTIVE: This study assessed BF and GDM in relation to the prevalence of prediabetes and MetS in Hispanic children and adolescents (8-19 y). METHODS: This is a longitudinal study with 229 Hispanic children (8-13 y) with overweight/obesity, family history of diabetes, and an average of four annual visits (AV). Participants were categorized as follows: never (negative for prediabetes/MetS at all AVs), ever (positive for prediabetes/MetS at any visit), intermittent (positive for prediabetes/MetS at 1-2 AVs), and persistent (positive for prediabetes/MetS at greater than or equal to 3 AVs). RESULTS: Compared with GDM offspring who were not BF (referent), GDM offspring who were BF had lower odds of persistent prediabetes (OR = 0.18; 95% CI, 0.04-0.82; P = 0.02) and MetS (OR = 0.10; 95% CI, 0.02-0.55; P = 0.008). Compared with referent group, non-GDM offspring who were BF, and non-GDM offspring not BF had lower odds of persistent prediabetes (OR = 0.10; 95% CI, 0.03-0.39; P = 0.001; OR = 0.05; 95% CI, 0.01-0.11; P < 0.001) and MetS (OR = 0.14; 95% CI, 0.04-0.59; P = 0.01 and OR = 0.04; 95% CI, 0.01-0.11; P < 0.001). CONCLUSIONS: These results show BF is protective against prediabetes and MetS in offspring regardless of GDM status.

Design and participant characteristics of TX sprouts: A school-based cluster randomized gardening, nutrition, and cooking intervention.

AIMS: To outline the study design, outcome measures, protocol and baseline characteristics of enrolled participants of Texas (TX) Sprouts, a one-year school-based gardening, nutrition, and cooking cluster randomized trial. METHODS: Eight schools were randomly assigned to the TX Sprouts intervention and eight schools to the delayed intervention over three years (2016-2019). The intervention arm received: formation/training of Garden Leadership Committees; a 0.25-acre outdoor teaching garden; 18 student lessons including gardening, nutrition, and cooking activities, taught weekly during school hours by hired educators throughout one school year; and nine parent lessons taught monthly to families. The delayed intervention was implemented the following academic year and received the same protocol as the intervention arm. Primary outcomes included: dietary intake, dietary-related behaviors, obesity, and metabolic parameters. Child measures included: height, weight, waist circumference, body composition, blood pressure, and dietary psychosocial variables. A subsample of children were measured for glucose, hemoglobin-A1C, and 24-hour dietary recalls. Parent measures included: height and weight, dietary intake, and related dietary psychosocial variables.
