Background: School gardening interventions typically include cooking and gardening (CG) components; however, few studies have examined associations between CG psychosocial behaviors (attitudes, self-efficacy, and motivation), dietary intake, and obesity parameters. This study assessed the association between changes in CG behaviors with changes in dietary intake and obesity in participants of the LA Sprouts study, an after-school, 12-week, randomized controlled CG intervention conducted in four inner-city elementary schools in Los Angeles.Methods: Process analysis using data from 290 low-income, primarily Hispanic/Latino third through fifth-grade students who were randomized to either the LA Sprouts intervention (n = 160) or control group (n = 130). Height, weight, waist circumference, dietary intake via questionnaire, and CG behaviors were collected at baseline and postintervention. Linear regressions determined whether changes in CG behaviors predicted changes in dietary intake and obesity outcomes.Results: There were no differences in changes in CG psychosocial behaviors between intervention and control groups, therefore groups were combined. Participants were 49% male, 87% Hispanic/Latino, and an average age of nine. Increases in cooking behaviors significantly predicted increases in dietary fiber intake ( p = 0.004) and increases in vegetable intake ( p = 0.03). Increases in gardening behaviors significantly predicted increased intake of dietary fiber ( p = 0.02). Changes in CG behaviors were not associated with changes in BMI z-score or waist circumference.Conclusions: Results from this study suggest that school-based interventions should incorporate CG components, despite their potentially costly and time-intensive nature, as these behaviors may be responsible for improvements in dietary intake of high-risk minority youth.

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 (β = 3.26; 95% CI: 1.67, 4.86; P < 0.01 and β = 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 (β = 2.45; 95% CI: 1.47, 3.44; P < 0.01 and β = 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, (β = 1.47; 95% CI: 0.51, 2.42; P < 0.01, and β = 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.

Studies examining the impact of food insecurity on metabolic markers are limited, specifically in Hispanic youth. This study was a cross-sectional analysis of 218 3rd-5th grade students (83% Hispanic and 49% male). Anthropometrics, blood glucose, insulin, and lipids via fasting blood draw, dietary intake via Block screener, and a 5-item food security scale were collected. HOMA-Insulin Resistance was calculated. Multivariate analyses of covariance were used to examine differences in glucose and insulin indices, adiposity, metabolic and dietary intake variables between categories of food security. Food secure children had greater glycemic control and decreased insulin resistance compared to food insecure children.

SummaryResearch examining the impact of artificial sweetened beverages (ASBs) on obesity and metabolic diseases in adolescents is limited. The overall goal is to examine the longitudinal effects of ASBs on changes in adiposity and metabolic parameters in Hispanic adolescents. Longitudinal cohort with 98 Hispanics (12–18 years) who were overweight or had obesity with the following data at baseline and 1‐year later: anthropometrics, diet (24‐h recalls), body composition (DXA), glucose and insulin dynamics (oral glucose tolerance and frequently sampled intravenous glucose tolerance test) and fasting lipids. Repeated measures analyses of covariance assessed changes over time between control (no ASBs at either visit), ASB initiators (no ASBs at baseline/ASBs at 1‐year) and chronic ASB consumers (ASBs at both visits). ASB initiators (n = 14) and chronic ASB consumers (n = 9) compared to control (n = 75) had higher total body fat at baseline and 1‐year (P = 0.05 for group effect). Chronic ASB consumers had a 6% increase in haemoglobin A1c, 34% increase in energy intake (kcal d−1) and 39% increase in carbohydrate intake (g d−1) over time, while control and ASB initiators maintained (P < 0.05 for group‐by‐time interactions). These results do not support promoting ASBs as a strategy for adiposity loss or to improve metabolic health.

Objectives This study assessed how child cooking involvement (CCI) and parental support in food preparation (PS) are related to vegetable preference (VP), vegetable intake (VI), and fruit intake (FI) in children participating in the Texas, Grow! Eat! Go! (TGEG) randomized controlled trial. Methods Baseline data from the TGEG intervention, conducted in 28 low-income, primarily Hispanic schools across Texas, was used for this study, and included 1325 3rd grade students and their parents. Schools were assigned to: (1) control group; (2) school garden intervention [Learn, Grow, Eat & Go! (LGEG)]; (3) physical activity intervention [Walk Across Texas (WAT)]; or (4) combined group (LGEG plus WAT). Height (via stadiometer), weight (via Tanita scale), dietary intake and CCI (via child questionnaire), and PS (via parent questionnaire) were collected. General Linear Models examined variations in baseline VP, VI, and FI with baseline CCI and PS. A priori covariates for all analyses included: TGEG treatment group, age, sex, and ethnicity. Results Students were 49.2% male and 42.4% Hispanic with a mean age of 8.3 ± 0.6; 78.3% of the population had overweight/obesity. Children who never cooked with their families preferred fewer vegetables than children who sometimes/always cooked with their parents (7.0 ± 0.6 vs. 8.7 ± 0.5 and 9.4 ± 0.5 vegetables, respectively; P < 0.001). Children who never cooked with their families ate less vegetables than children who sometimes/always cooked with their parents (1.9 ± 0.4 vs. 2.6 ± 0.3 and 3.5 ± 0.3 servings/day, respectively; P = 0.003 and P = 0.000, respectively). Children who never cooked with their families ate less fruit than children who sometimes/always cooked with their parents (1.2 ± 0.2 vs. 1.5 ± 0.1 and 2.09 ± 0.1 servings/day, respectively; P < 0.001). Conclusions Interventions including family cooking activities with children may be an effective way to increase vegetable preference and intake, and fruit intake, especially in high-risk, minority children.
