The distribution of food and nutrition policies and practices from 28 US states representing 6,732 secondary schools was evaluated using data from the 2008 School Health Profiles principal survey. School policies and practices evaluated were: availability of low-nutrient, energy-dense (LNED) snacks/drinks; use of healthy eating strategies; banning food marketing; availability of fruits and vegetables; and food package sizes. For each school, school-level demographic characteristics (percentage of students enrolled in free/reduced-price meals, minority enrollment, and geographic location) were also evaluated. Schools in small town/rural locations had significantly fewer policies that support healthy eating strategies and ban food marketing, and were less likely to serve fruits and vegetables at school celebrations, have fruits and vegetables available in vending or school stores, and limit serving-size packages. Schools serving the highest percentage of minority students consistently reported the same or better school food environments. However, schools serving the highest percentage of low-income students had varied results: vending and LNED vending policies were consistently better and fruit and vegetable availability–related policies were consistently worse. Disparities in the distribution of policies and practices that promote healthy school food environments seem most pronounced in small town/rural schools. The data also support the need for continued reinforcement and the potential for expansion of these efforts in urban and suburban areas and schools with highest minority enrollment.  相似文献

BackgroundBreakfast consumption is associated with better diet quality and healthier weights, yet many adolescents miss breakfast. Nationally, 17.1% of students participate in the School Breakfast Program (SBP). Only 10% of high school students participate.ObjectiveOur aim was to evaluate an environmental intervention to increase SBP participation in high schools.DesignA group randomized trial was carried out from 2012 to 2015.Participants/settingNinth- and 10th-grade students enrolled in 16 rural schools in Minnesota (median 387 students) were randomized to intervention or control condition.InterventionA school-based intervention that included two key components was implemented over a 12-month period. One component focused on increasing SBP participation by increasing student access to school breakfast through changes in school breakfast service practices (eg, serving breakfast from a grab-n-go cart in the atrium; expanding breakfast service times). The other component focused on promoting school breakfast through student-directed marketing campaigns.Main outcome measureChange in school-level participation in the SBP was assessed between baseline (among ninth and tenth graders) and follow-up (among tenth and eleventh graders). School meal and attendance records were used to assess change in school-level participation rates in the SBP.Statistical analysesThe Wilcoxon test was used for analysis of difference in change in mean SBP participation rate by experimental group.ResultsThe median change in SBP participation rate between baseline and follow-up was 3% (interquartile range=13.5%) among the eight schools in the intervention group and 0.5% (interquartile range=0.7%) among the eight schools in the control group. This difference in change between groups was statistically significant (Wilcoxon test, P=0.03). The intervention effect increased throughout the intervention period, with change in mean SBP participation rate by the end of the school year reaching 10.3% (95% CI 3.0 to 17.6). However, among the intervention schools, the change in mean SBP participation rates was highly variable (range=–0.8% to 24.8%).ConclusionsInterventions designed to improve access to the SBP by reducing environmental and social barriers have potential to increase participation among high school students.  相似文献

This article discusses a three-year Canadian project that created common Evaluation Frameworks for Fetal Alcohol Spectrum Disorder (FASD) support programs and for FASD prevention programs (i.e., programs serving people living with FASD and programs serving pregnant women and mothers). The project’s mixed-methods approach included a comprehensive literature search and consultations across Canada with multi-disciplinary service providers, program funders, researchers, and evaluators. These activities led to development of three visual “maps” depicting evaluation of: a) FASD support programs; b) FASD prevention programs; and c) FASD programming in Aboriginal communities. In addition, the team provided mentoring and evaluation-related support to program staff, funders and/or partners of five community-based FASD-related agencies. Informed by a social determinants of health lens, the maps are comprised of concentric rings showing programs’: theoretical foundations; activities; program outcomes; and wholistic participant, community and systemic outcomes. The article also shares findings regarding the applicability and utility of the Frameworks and of evaluation-related mentoring.  相似文献

Disaster literature suggests that children's and adolescents’ post-disaster reactions vary according to their developmental levels. Preschool children show less psychological problems as compared to older children and adolescents, but they have a higher incidence of trauma-specific fears and behavioral problems (e.g., dependency, clinging). School-age children's disaster responses include sleep and eating disturbances, behavioral problems, and poor school performance. Adolescents tend to exhibit symptoms such as posttraumatic stress disorder, depression, anxiety, belligerence, and pessimistic views about the future (Korol, Green, &; Gleser, ).  相似文献
