USDA Snack Policy Implementation: Best Practices From the Front Lines, United States, 2013-2014

Four very basic ways to think about policy in implementation science

BACKGROUND

Policy is receiving increasing attention in the field of implementation science. However, there remains a lack of clear, concise guidance about how policy can be conceptualized in implementation science research. Building on Curran's article "Implementation science made too simple"-which defines "the thing" as the intervention, practice, or innovation in need of implementation support-we offer a typology of four very basic ways to conceptualize policy in implementation science research. We provide examples of studies that have conceptualized policy in these different ways and connect aspects of the typology to established frameworks in the field. The typology simplifies and refines related typologies in the field. Four very basic ways to think about policy in implementation science research. 1) Policy as something to adopt: an evidence-supported policy proposal is conceptualized as "the thing" and the goal of research is to understand how policymaking processes can be modified to increase adoption, and thus reach, of the evidence-supported policy. Policy-focused dissemination research is well-suited to achieve this goal. 2) Policy as something to implement: a policy, evidence-supported or not, is conceptualized as "the thing" and the goal of research is to generate knowledge about how policy rollout (or policy de-implementation) can be optimized to maximize benefits for population health and health equity. Policy-focused implementation research is well-suited to achieve this goal. 3) Policy as context to understand: an evidence-supported intervention is "the thing" and policies are conceptualized as a fixed determinant of implementation outcomes. The goal of research is to understand the mechanisms through which policies affect implementation of the evidence-supported intervention. 4) Policy as strategy to use: an evidence-supported intervention is "the thing" and policy is conceptualized as a strategy to affect implementation outcomes. The goal of research is to understand, and ideally test, how policy strategies affect implementation outcomes related to the evidence-supported intervention.

CONCLUSION

Policy can be conceptualized in multiple, non-mutually exclusive ways in implementation science. Clear conceptualizations of these distinctions are important to advancing the field of policy-focused implementation science and promoting the integration of policy into the field more broadly.

Readiness of SNAP-Ed Implementers to Incorporate Policy, Systems, and Environmental Approaches into Programming

OBJECTIVE

To identify the readiness of Supplemental Nutrition Assistance Program Education (SNAP-Ed) implementers to facilitate policy, systems, and environmental (PSE) changes in conjunction with delivering direct nutrition education.

DESIGN

Qualitative study using semistructured interviews.

SETTING

A southeastern state.

PARTICIPANTS

Purposive sample of SNAP-Ed staff (n = 19) from state implementing agencies (n = 3) in 1 state.

PHENOMENON OF INTEREST

Readiness using the validated framework: readiness equals motivation coupled with general-capacities and innovation-specific capacities (R = MC²).

ANALYSIS

Interviews were audio-recorded and transcribed verbatim. Transcripts were analyzed using an iterative approach to the analysis via emergent coding and constant comparison.

RESULTS

Although a general sense of motivation is present among implementers to meet the new federal guidelines, nutrition education is still prioritized. General capacity for SNAP-Ed implementers, comprised communication, training, and funding and staffing, was limited. Innovation-specific capacities around the implementation of PSEs revealed limited knowledge, experience, and resources among most implementers.

CONCLUSIONS AND IMPLICATIONS

Identifying the nuanced and interrelated aspects of motivation and capacity of SNAP-Ed implementers to incorporate PSEs into their direct education interventions could inform tailored strategies for increasing readiness, such as through training, reallocation of resources, or program restructuring.

Improving the school food environment for the prevention of childhood obesity: What works and what doesn't

The food environment has a significant influence on dietary choices, and interventions designed to modify the food environment could contribute to the prevention of childhood obesity. Many interventions have been implemented at the school level, but effectiveness in addressing childhood obesity remains unclear. We undertook a systematic review, a meta-analysis, and meta-regression analyses to assess the effectiveness of interventions on the food environment within and around schools to improve dietary intake and prevent childhood obesity. Estimates were pooled in a random-effects meta-analysis with stratification by anthropometric or dietary intake outcome. Risk of bias was formally assessed. One hundred papers were included. Interventions had a significant and meaningful effect on adiposity (body mass index [BMI] z score, standard mean difference: -0.12, 95% confidence interval: 0.15, 0.10) and fruit consumption (portions per day, standard mean difference: +0.19, 95% confidence interval: 0.16, 0.22) but not on vegetable intake. Risk of bias assessment indicated that n = 43 (81%) of non-randomized controlled studies presented a high risk of bias in the study design by not accounting for a control. Attrition bias (n = 34, 79%) and low protection of potential contamination (n = 41, 95%) presented the highest risk of bias for randomized controlled trials. Changes in the school food environment could improve children's dietary behavior and BMI, but policy actions are needed to improve surrounding school food environments to sustain healthy dietary intake and BMI.

Process evaluation of fruit and vegetables distribution interventions in school-based settings: A systematic review

•

Assesses how school fruit & vegetable distribution interventions are implemented.

•

Child fruit & vegetable intake is influenced by how intervention is implemented.

•

Recommendations for implementing fruit & vegetable interventions in schools.

•

Studies should also consider sustainability, cost-effectiveness and implementation.

Despite the importance of process evaluation in program evaluations, research has focused primarily on the effectiveness of fruit and vegetables (FVs) distribution interventions on children’s consumption, with little attention given to how these interventions achieve their outcomes. Five bibliographic databases (Embase, PubMed, ProQuest, Scopus, and Web of Science Core Collection) were searched in June 2019 for studies of interventions where the main focus was the implementation of distributed FVs to school-aged children as a snack. The Critical Appraisal Skills Programme (CASP) tool was used to appraise the risk of bias within included studies. Data were extracted based on study characteristics and findings. Results identified 24 studies reporting on 11 interventions and 1 policy. The findings of this systematic review indicate that the majority of the studies included limited references to implementation research. Recurring limitations include an absence of an evaluation theoretical framework and the data collection methods used. Also, several factors were identified as informing the success of snack-based FVs distribution programs, including participation of the school community, school characteristics, background knowledge, and parental engagement. Lack of timely FVs delivery, limited funding, inadequate awareness about the program, insufficient teachers’ time, and food waste were identified as challenges to successful programming. Findings indicate that distributing FVs to school-aged children as a snack can increase their consumption, but only with proper implementation. Further evaluative research is required to better inform future implementation of snack-based FV distribution interventions in school settings.

Association of State Laws Regarding Snacks in US Schools With Students' Consumption of Solid Fats and Added Sugars

IMPORTANCE

The Smart Snacks in School standards (hereafter, Smart Snacks) were issued in 2013 with the aim of improving students' dietary intake behaviors. Goals of Smart Snacks included reducing total energy intake, consumption of solid fats and added sugars, and sodium intake. Smart Snacks standards were required to be implemented by the start of the 2014 to 2015 school year at all US schools participating in federal child nutrition programs.

OBJECTIVE

To examine the association of state laws that specifically direct schools to implement Smart Snacks with student dietary consumption outcomes.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study used nationally representative data collected in the 2014 to 2015 school year as part of the School Nutrition and Meal Cost Study. Students in grades 1 through 12 (ages approximately 6-18 years) were randomly selected from 310 public schools in 30 US states and the District of Columbia. Analytic weights were applied and all percentages reported are weighted. Analyses were conducted from March 1, 2018, to December 12, 2019.

EXPOSURES

State laws requiring schools to implement Smart Snacks.

MAIN OUTCOMES AND MEASURES

A 24-hour recall was used to assess student dietary intake as daily kilocalories consumed as (a) total energy, (b) solid fats and added sugars combined, (c) solid fats, or (d) added sugars. Milligrams of daily sodium consumption were also computed.

RESULTS

Among 1959 students (mean [SD] age, 11.9 [3.5] years; 1014 [50.9%] boys), 420 students (22.5%) attended school in a state with Smart Snacks laws, and 528 students (26.1%) consumed snacks obtained at school. In covariate-adjusted models, total energy intake did not vary based on state law. Adjusted mean daily kilocalories from solid fats and added sugars was significantly lower among students in states with laws (508.7 [95% CI, 463.0 to 554.4] kcal) than among students in states without laws (562.5 [95% CI, 534.3 to 590.8] kcal; difference, -53.9 [95% CI, -104.5 to -3.2] kcal; P = .04). Consumption of sodium did not differ by state law. Kilocalories from solid fats contributed more to the difference than kilocalories from added sugars (-37.7 [95% CI -62.8 to -12.6] kcal vs -16.2 [95% CI, -51.3 to 19.0] kcal).

CONCLUSIONS AND RELEVANCE

These findings suggest that students in states with laws requiring schools to implement Smart Snacks had better dietary intake than students in states without laws, consuming a mean of 53.9 fewer kilocalories from solid fats and added sugars per day, after adjusting for covariates. State-level policy mechanisms may support schools' implementation of federal standards in ways that are associated with healthier diets among children and adolescents.

Public Policies to Reduce Sugary Drink Consumption in Children and Adolescents

Excess consumption of added sugars, especially from sugary drinks, poses a grave health threat to children and adolescents, disproportionately affecting children of minority and low-income communities. Public policies, such as those detailed in this statement, are needed to decrease child and adolescent consumption of added sugars and improve health.

Factors Influencing the Implementation of Nutrition Policies in Schools: A Scoping Review

BACKGROUND

Although school nutrition policies (SNPs) have been highlighted as an important intervention to support childhood nutrition, their implementation and maintenance within real-word settings is complex. There is a need to understand the factors that influence implementation by consolidating existing research and identifying commonalities and differences.

AIMS

The purpose of this review is to determine what is known about the influence of broad and local system factors on the implementation of SNPs internationally.

METHOD

This scoping review involved identifying and selecting relevant literature that related SNP implementation in primary and secondary schools. Following the search process, 2,368 articles were screened and 59 articles were synthesized and charted and emerging themes were identified.

RESULTS

Across the final studies identified, factors emerged as barriers and facilitators to the implementation of SNPs, with system implications that related to five areas to support policy action: providing macro-level support may encourage policy implementation; addressing the financial implications of healthy food access; aligning nutrition and core school priorities; developing a common purpose and responsibility among stakeholders; recognition of school and community characteristics.

DISCUSSION

While SNPs can help to support childhood nutrition, strategies to address issues related to policy implementation need to be taken to help schools overcome persistent challenges.

CONCLUSION

The results of this review provide opportunities for action across multiple system levels to ensure synergy and coordinated action toward SNP goals to foster the creation supportive nutrition environments for children.

Views of policy makers and health promotion professionals on factors facilitating implementation and maintenance of interventions and policies promoting physical activity and healthy eating: results of the DEDIPAC project

Background

The uptake, implementation, and maintenance of effective interventions promoting physical activity (PA) and a healthy diet and the implementation of policies targeting these behaviors are processes not well understood. We aimed to gain a better understanding of what health promotion professionals and policy makers think are important factors facilitating adoption, implementation, and maintenance of multi-level interventions and policies promoting healthy eating and PA in Belgium, Germany, Ireland, Norway, and Poland.

Methods

Six interventions and six policies were identified based on pre-defined criteria. Forty semi-structured interviews were conducted with stakeholders from various sectors to elicit information on factors impacting adoption, implementation, and maintenance of these interventions and policies. All interview transcripts were coded in NVivo, using a common categorization matrix. Coding in the respective countries was done by one researcher and validated by a second researcher.

Results

Active involvement of relevant stakeholders and good communication between coordinating organizations were described as important factors contributing to successful adoption and implementation of both interventions and policies. Additional facilitating factors included sufficient training of staff and tailoring of materials to match needs of various target groups. The respondents indicated that maintenance of implemented interventions/policies depended on whether they were embedded in existing or newly created organizational structures in different settings and whether continued funding was secured.

Conclusions

Despite considerable heterogeneity of interventions and health policies in the five countries, stakeholders across these countries identify similar factors facilitating adoption, implementation, and maintenance of these interventions and policies.

Insights on the Intersection of Health Equity and School Nutrition Policy Implementation: An Exploratory Qualitative Secondary Analysis

BACKGROUND

Recent federal policies aimed to ensure that all children have equitable access to healthy school nutrition environments. However, historically, disparities have persisted in the quality of school nutrition environments across geographic and socioeconomic groups. There is limited literature addressing if and how recent efforts to reform the school nutrition environment have influenced such disparities. The main objective of this study was to explore stakeholders' insights on how school nutrition reform intersected with issues of inequity.

METHOD

Qualitative secondary analysis (QSA) offers a unique method to examine existing data with a related but distinct inquiry. This QSA analyzed three primary studies, including stakeholder interviews and focus group data with school professionals and students (total 60 transcripts). Two trained analysts iteratively coded all transcripts in Atlas.ti Version 7 and followed principles of constant comparative analysis. Measures to enhance "trustworthiness" were built into the primary studies and the QSA.

RESULTS

Broadly, stakeholders' complex insights about the school food environments' ability to compensate for healthy dietary options and "whole child" education that were perceived to be lacking in home environments. Despite the majority of respondents' positive perceptions of reforms, they also noted the challenges of addressing disparities due to family home environments and complex socioeconomic conditions. Overall, respondents reported that school food reform and nutrition education had the potential for long-term impacts on students' health, including the potential to improve disparities through enhanced academic achievement for disadvantaged populations.

DISCUSSION AND CONCLUSION

QSA allowed for inquiry into frontline stakeholders' understandings of how school nutrition reform may affect health inequities. Qualitative methods allowed for the examination of complex motivations and perspectives involved in policy implementation. Understanding frontline stakeholders' perspectives is key to advance school nutrition reform in a sustainable manner, especially in light of the federal local school wellness policy final rule.

Successes and Challenges in School Meal Reform: Qualitative Insights From Food Service Directors

BACKGROUND

The Healthy, Hunger-Free Kids Act of 2010 (HHFKA) directed the US Department of Agriculture (USDA) to revise school meal standards to increase healthy food offerings. A critical stakeholder in the implementation of standards is Food Service Directors (FSDs). We sought to examine FSDs' perspectives on revised school meal standards to gain insight into successful implementation strategies.

METHODS

Semistructured interviews were conducted with FSDs (N = 9) from high schools that had achieved HealthierUS Schools Challenge: Smarter Lunchrooms (HUSSC: SL) status. Qualitative interview data were team coded in Atlas.ti v7 and analyzed with principles of constant comparative analysis.

RESULTS

FSDs reported overall positive perceptions of the revised school meal standards and its potential impacts, as well as improved fruit and vegetable consumption, despite initial challenges with plate waste, procurement of whole grain-rich products, and fast paced sodium targets. Implementation was described as complex, ongoing processes; with time and in-service trainings, student acceptance to these changes improved.

CONCLUSIONS

These findings are directly relevant to future reauthorization of the Child Nutrition Act and to revisions to the implementation time line for the federal school meal standards related to sodium, whole grains, and flavored milk. Insights into FSDs' strategies suggest that more time and targeted technical assistance at federal, state, and local levels is warranted.
