Background: Most children do not eat enough fruits and vegetables (FV). Schools are a critical setting for supporting children to consume FV. To fill a gap in available materials, a classroom curriculum was developed and evaluated to determine impacts on student FV-related knowledge, attitudes, and behaviors. Methods: A pre-/post-intervention survey was administered to 4th-6th grade students in 3 intervention and one comparison schools. Post-intervention student focus groups, parent/guardian surveys, and teacher surveys provided complementary information. Results: Intervention students had a significantly greater increase in total FV intake, fruit intake, and 100% juice consumption, and preference for several types of FV relative to comparison group students. Students, teachers, and parents reported overall high levels of satisfaction with the curriculum. Conclusions: The Harvest of the Month curriculum is effective at increasing fruit intake among a low-income, diverse student population in grades 4-6, is acceptable to students, teachers, and parents, and is feasible to implement. Findings suggest this impact is the result of changes in preferences, skills, and motivation but not self-efficacy or perceived social norms. Some tailoring of the curriculum may be needed to increase its appropriateness for 6th-grade students, increase the impact on vegetable intake, and limit intake of juice.

BackgroundOur objective was to examine the association between school wellness committees and implementation of nutrition wellness policies and children's weight status and obesity-related dietary outcomes.MethodsA cross-sectional study was conducted of 4790 children aged 4-15 years recruited from 130 communities in the Healthy Communities Study. Multilevel statistical models assessed associations between school wellness policies and anthropometric (body mass index z-score [BMIz]) and nutrition measures, adjusting for child and community-level covariates.ResultsChildren had lower BMI z-scores (-0.11, 95% confidence interval [CI]: -0.19, -0.03) and ate breakfast more frequently (0.14 days/week, 95% CI: 0.02-0.25) if attending a school with a wellness committee that met once or more in the past year compared to attending a school with a wellness committee that did not meet/did not exist. Children had lower added sugar (p < .0001), lower energy-dense foods (p = .0004), lower sugar intake from sugar-sweetened beverages (p = .0002), and lower dairy consumption (p = .001) if attending a school with similar or stronger implementation of the nutrition components of the school wellness policies compared to other schools in the district.ConclusionsA more active wellness committee was associated with lower BMI z-scores in US schoolchildren. Active school engagement in wellness policy implementation appears to play a positive role in efforts to reduce childhood obesity.

Background: This study sought to elucidate students' perceptions of school food environments and to assess correlations between perceptions and purchasing and consumption behaviors at school. Methods: Seventh and ninth graders (n = 5365) at 19 schools in multiethnic, low-income California communities participating in the Healthy Eating Active Communities program completed questionnaires assessing their attitudes and behaviors regarding school food environments during spring 2006. Results: Most students (69%) reported that fresh fruit was important to be able to buy at school; more than chips (21%), candy (28%), or soda (31%). Reported importance of food offerings was correlated with the consumption of those items. Most students did not perceive foods/beverages offered at school to be healthy; fewer than a quarter reported eating fruits or vegetables (FV) at school. Students eating school lunch were more than twice as likely to consume FV, though if they also purchased from competitive venues, their consumption of candy, chips, and soda was similar to their peers who purchased only competitive foods. Conclusion: Students report healthy foods to be important to be able to buy at school, but do not perceive their school food environment to be healthy and consume more unhealthy foods at school. Students served healthy items via school lunch are more likely to consume them; however, they also purchase and consume unhealthy items if available. Findings suggest that modifying school food environments to facilitate consumption of healthy foods and limit unhealthy foods will better match students' preferences and could lead to improved dietary intake.
