Virtual Sprouts: A Virtual Gardening Pilot Intervention Increases Self-Efficacy to Cook and Eat Fruits and Vegetables in Minority Youth.

ABSTRACT: OBJECTIVE:To examine the effect of the Virtual Sprouts intervention, an interactive multiplatform mobile gardening game, on dietary intake and psychosocial determinants of dietary behavior in minority youth. MATERIALS AND METHODS:In this quasi-experimental pilot intervention, 180 third-, fourth-, and fifth-grade students in Los Angeles Unified School District participated in a 3-week program that included three Virtual Sprouts gaming sessions, three in-school lessons, and three in-home activities, using a nutrition- and gardening-focused curriculum. Pre- and postintervention questionnaires were used to assess psychosocial determinants of dietary behavior, including knowledge about and self-efficacy to eat fruits and vegetables (FV). Data were collected on FV, whole grains, fiber, total sugar, added sugar, and energy from sugary beverages through the Block Kids Food Screener ("last week" version) for Ages 2-17. Repeated measures analysis of covariance models was used for continuous outcomes, controlling for age, sex, ethnicity, school, and free school lunch. RESULTS:After the intervention, the intervention group (n?=?116) compared with the control group (n?=?64) had a significantly improved self-efficacy to eat FV score (+1.6% vs. -10.3%, P?=?0.01), and an improved self-efficacy to cook FV score (+2.9% vs. -5.0%, P?=?0.05). There were no significant differences in dietary intake or self-efficacy to garden scores between intervention and control groups. CONCLUSION:The results from this 3-week pilot study suggest that an interactive mobile game with a nutrition- and gardening-focused curriculum can improve psychosocial determinants of dietary behavior in minority youth.

Project description:Vegetables harboring bacteria resistant to antibiotics are a growing food safety issue. However, data concerning carbapenem-resistant Enterobacteriaceae (CRE) in ready-to-eat fresh vegetables is still rare. In this study, 411 vegetable samples from 36 supermarkets or farmer's markets in 18 cities in China, were analyzed for CRE. Carbapenemase-encoding genes and other resistance genes were analyzed among the CRE isolates. Plasmids carrying carbapenemase genes were studied by conjugation, replicon typing, S1-PFGE southern blot, restriction fragment length polymorphism (RFLP), and sequencing. CRE isolates were also analyzed by pulsed-field gel electrophoresis (PFGE). Ten vegetable samples yielded one or more CRE isolates. The highest detection rate of CRE (14.3%, 4/28) was found in curly endive. Twelve CRE isolates were obtained and all showed multidrug resistance: Escherichia coli, 5; Citrobacter freundii, 5; and Klebsiella pneumoniae, 2. All E. coli and C. freundii carried blaNDM, while K. pneumoniae harbored blaKPC-2. Notably, E. coli with blaNDM and ST23 hypervirulent Klebsiella pneumoniae (hvKP) carrying blaKPC-2 were found in the same cucumber sample and clonal spread of E. coli, C. freundii, and K. pneumoniae isolates were all observed between vegetable types and/or cities. IncX3 plasmids carrying blaNDM from E. coli and C. freundii showed identical or highly similar RFLP patterns, and the sequenced IncX3 plasmid from cucumber was also identical or highly similar (99%) to the IncX3 plasmids from clinical patients reported in other countries, while blaKPC-2 in K. pneumoniae was mediated by similar F35:A-:B1 plasmids. Our results suggest that both clonal expansion and horizontal transmission of IncX3- or F35:A-:B1-type plasmids may mediate the spread of CRE in ready-to-eat vegetables in China. The presence of CRE in ready-to-eat vegetables is alarming and constitutes a food safety issue. To our knowledge, this is the first report of either the C. freundii carrying blaNDM, or K. pneumoniae harboring blaKPC-2 in vegetables. This is also the first report of ST23 carbapenem-resistant hvKP strain in vegetables.

Project description:Fresh fruits and vegetables can harbor large and diverse populations of bacteria. However, most of the work on produce-associated bacteria has focused on a relatively small number of pathogenic bacteria and, as a result, we know far less about the overall diversity and composition of those bacterial communities found on produce and how the structure of these communities varies across produce types. Moreover, we lack a comprehensive view of the potential effects of differing farming practices on the bacterial communities to which consumers are exposed. We addressed these knowledge gaps by assessing bacterial community structure on conventional and organic analogs of eleven store-bought produce types using a culture-independent approach, 16 S rRNA gene pyrosequencing. Our results demonstrated that the fruits and vegetables harbored diverse bacterial communities, and the communities on each produce type were significantly distinct from one another. However, certain produce types (i.e., sprouts, spinach, lettuce, tomatoes, peppers, and strawberries) tended to share more similar communities as they all had high relative abundances of taxa belonging to the family Enterobacteriaceae when compared to the other produce types (i.e., apples, peaches, grapes, and mushrooms) which were dominated by taxa belonging to the Actinobacteria, Bacteroidetes, Firmicutes, and Proteobacteria phyla. Although potentially driven by factors other than farming practice, we also observed significant differences in community composition between conventional and organic analogs within produce types. These differences were often attributable to distinctions in the relative abundances of Enterobacteriaceae taxa, which were generally less abundant in organically-grown produce. Taken together, our results suggest that humans are exposed to substantially different bacteria depending on the types of fresh produce they consume with differences between conventionally and organically farmed varieties contributing to this variation.
