RESUMO

Breakfast consumption among youth is associated with improved diet quality, weight, cognition, and behavior. However, not all youth in the United States consume breakfast. Participation in the School Breakfast Program (SBP) is also low relative to the lunch program. Universal free breakfast (UFB) policies have been implemented to increase breakfast participation by reducing cost and stigma associated with the SBP. This study examined whether a UFB policy implemented in a school district in the Southeast US was associated with changes in breakfast participation, school attendance, and student weight. A longitudinal study of secondary data was conducted, and a mixed modeling approach was used to assess patterns of change in SBP participation. General linear models were used to assess attendance and student weight change. On average, across schools in the district, there was an increase in breakfast participation of 4.1 percentage points following the implementation of the policy. The change in breakfast participation in schools differed by the percent of students in the school who received school meals for free or at a reduced price, the percent of students of color, and the grade level of the school. Increases in SBP participation were not associated with significant changes in attendance or weight. UFB policies may be effective in increasing participation in the SBP.

RESUMO

Overall impact of public health prevention interventions relies not only on the average efficacy of an intervention, but also on the successful adoption, implementation, and maintenance (AIM) of that intervention. In this study, we aim to understand the dynamics that regulate AIM of organizational level intervention programs. We focus on two well-documented obesity prevention interventions, implemented in food carry-outs and stores in low-income urban areas of Baltimore, Maryland, which aimed to improve dietary behaviour for adults by providing access to healthier foods and point-of-purchase promotions. Building on data from field observations, in-depth interviews, and data discussed in previous publications, as well as the strategy and organizational behaviour literature, we developed a system dynamics model of the key processes of AIM. With simulation analysis, we show several reinforcing mechanisms that span stakeholder motivation, communications, and implementation quality and costs can turn small changes in the process of AIM into big difference in the overall impact of the intervention. Specifically, small changes in the allocation of resources to communication with stakeholders of intervention could have a nonlinear long-term impact if those additional resources can turn stakeholders into allies of the intervention, reducing the erosion rates and enhancing sustainability. We present how the dynamics surrounding communication, motivation, and erosion can create significant heterogeneity in the overall impact of otherwise similar interventions. Therefore, careful monitoring of how those dynamics unfold, and timely adjustments to keep the intervention on track are critical for successful implementation and maintenance.

RESUMO

In this study, we present case studies to explore the dynamics of implementation and maintenance of health interventions. We analyze how specific interventions are built and eroded, how the building and erosion mechanisms are interconnected, and why we can see significantly different erosion rates across otherwise similar organizations. We use multiple comparative obesity prevention case studies to provide empirical information on the mechanisms of interest, and use qualitative systems modeling to integrate our evolving understanding into an internally consistent and transparent theory of the phenomenon. Our preliminary results identify reinforcing feedback mechanisms, including design of organizational processes, motivation of stakeholders, and communication among stakeholders, which influence implementation and maintenance of intervention components. Over time, these feedback mechanisms may drive a wedge between otherwise similar organizations, leading to distinct configurations of implementation and maintenance processes.

RESUMO

Little is known about the barriers and facilitators to local food procurement among women of reproductive age (WRA). Therefore we conducted qualitative interviews with WRA in rural eastern and western NC (ENC and WNC) to learn of factors related to locally sourced food procurement. In-depth interviews were conducted among low-income White, Black, and Hispanic English-speaking WRA (N=62 (ENC: 37; WNC: 23) (18-44 years)). Independent coders used a consensus codebook to double-code all transcripts. Coders then came together to discuss and resolve coding discrepancies, and identified themes and salient quotes. Cross-cutting themes from both ENC and WNC participants included access to local food sources; acceptance of Supplemental Nutrition Assistance Program/Electronic Benefit Transfer (SNAP/EBT); freshness of produce; support for local agriculture; and the community aspect of local food sourcing. The in-depth understanding gained from this study could be used to guide tailored policy and intervention efforts aimed at promoting fruit and vegetable consumption among low-income WRA.

RESUMO

BACKGROUND: California law has standards for physical education (PE) instruction in K-12 public schools; audits found that the Los Angeles Unified School District did not enforce the standards. In 2009, the district adopted a PE policy to comply with these standards. PURPOSE: This study aimed to evaluate the outcomes of the PE policy in district schools. METHODS: PE class observations were conducted using the System for Observing Fitness Instruction Time in the 2010-2011 and 2011-2012 school years in an income-stratified random sample of 34 elementary, middle, and high schools to assess changes in PE class size, class duration, and time students spent in moderate to vigorous physical activity. RESULTS: PE class duration increased in high-income elementary schools. Mean class size decreased in low-income middle schools. CONCLUSIONS: There was limited implementation of the PE policy 2 years after passage. Opportunities exist to continue monitoring and improving PE quantity and quality.

RESUMO

States and school districts around the country are developing policies that set nutrition standards for competitive foods and beverages sold outside of the US Department of Agriculture's reimbursable school lunch program. However, few tools exist for monitoring the implementation of these new policies. The objective of this research was to develop a computerized assessment tool, the Food and Beverage Environment Analysis and Monitoring System (FoodBEAMS), to collect data on the competitive school food environment and to test the inter-rater reliability of the tool among research and nonresearch professionals. FoodBEAMS was used to collect data in spring 2007 on the competitive foods and beverages sold in 21 California high schools. Adherence of the foods and beverages to California's competitive food and beverage nutrition policies for schools (Senate Bills 12 and 965) was determined using the data collected by both research and nonresearch professionals. The inter-rater reliability between the data collectors was assessed using the intraclass correlation coefficient. Researcher vs researcher and researcher vs nonresearcher inter-rater reliability was high for both foods and beverages, with intraclass correlation coefficients ranging from .972 to .987. Results of this study provide evidence that FoodBEAMS is a promising tool for assessing and monitoring adherence to nutrition standards for competitive foods sold on school campuses and can be used reliably by both research and nonresearch professionals.

RESUMO

PURPOSE: To determine extent and factors associated with implementation of California's school nutrition standards 1 year after standards became active. METHODS: Information on competitive foods and beverages available in schools was collected from a representative sample of 56 public high schools in California. Adherence to nutrition standards was calculated for each item and summarized for each school by venue. The association between schools' sociodemographic characteristics and adherence to standards was determined by multivariate analysis. RESULTS: The majority of schools were adhering to the required beverage standards. None of the schools selling competitive foods were 100% adherent to the food standards. Adherence to both standards tended to be highest in food service venues. In univariate analyses, percent nonwhite enrollment, population density, percent free/reduced-price (FRP) meal eligibility, and school size were significantly correlated with the beverage adherence rate. Percent nonwhite enrollment and population density remained significant in the multivariate regression model. Percent nonwhite enrollment and percent FRP meal eligibility were significantly correlated with the food adherence rate in univariate analysis, but neither remained significant in the multiple regression model. CONCLUSIONS: California high schools are making progress toward implementation of the state nutrition standards. Beverage standards appear easier to achieve than nutrient-based food standards. Additional support is needed to provide schools with resources to implement and monitor these policies. Simpler standards and/or a reduction in the foods and beverages sold could better enable schools to achieve and monitor adherence.
