Strength and comprehensiveness of district school wellness policies predict policy implementation at the school level

BACKGROUND: In 2006, all local education agencies in the United States participating in federal school meal programs were required to establish school wellness policies. This study documented the strength and comprehensiveness of 1 state's written district policies using a coding tool, and tested whether these traits predicted school‐level implementation and practices. METHODS: School wellness policies from 151 Connecticut districts were evaluated. School principal surveys were collected before and after the writing and expected implementation of wellness policies. Sociodemographic variables were assessed for each district, including enrollment, population density, political climate, racial composition, and socioeconomic status. Changes in school‐level policy implementation before and after the federal wellness policy mandate were compared across districts by wellness policy strength; policies were compared based on district‐level demographics. RESULTS: Statewide, more complete implementation of nutrition and physical activity policies at the school level was reported after adoption of written policies. Districts with stronger, more comprehensive policies were more successful in implementing them at the school level. Some sociodemographic characteristics predicted the strength of wellness policies. CONCLUSIONS: Written school wellness policies have the potential to promote significant improvements in the school environment. Future regulation of school wellness policies should focus on the importance of writing strong and comprehensive policies.     

Transparency and oversight in local wellness policies

BACKGROUND: Advocates have called for increased wellness policy transparency and oversight through the use of health advisory councils. This study examines (1) wellness policy transparency, (2) advisory council requirements, (3) factors associated with each, and (4) whether transparency or advisory council requirements are indicative of a stronger policy addressing nutrition and physical activity. METHODS: Policies for school year 2007–2008 were obtained from a nationally representative sample of 641 districts and analyzed for their applicability to elementary, middle, and high school levels. Main outcome measures included (1) policy transparency (online availability), (2) advisory council requirements, and (3) overall policy strength. T‐tests assessed variability in policy strength by transparency and advisory council requirements. Multivariate logistic and linear regression analyses controlled for district size, socioeconomic status, race/ethnicity, region, and locale; models of advisory council/policy strength relationships also controlled for state advisory council requirements. RESULTS: More than 41% of districts posted wellness policies online and more than 43% required advisory councils. Transparency was less likely in small‐/medium‐sized and non‐southern districts; and, for elementary school policies, most common in majority Hispanic districts. Advisory council requirements were less likely in small‐/medium‐sized districts for middle/high school policies and more likely in majority Hispanic districts for elementary school policies. After adjusting for all covariates, transparency was not associated with policy strength, but advisory council requirements significantly predicted policy strength. CONCLUSIONS: Transparency may facilitate awareness, but it does not mean that wellness policies will be stronger; however, advisory council requirements may be a marker for stronger policies.     

A Comprehensive Coding System to Measure the Quality of School Wellness Policies

In 2006, all local education agencies in the United States participating in the National School Lunch Program were required to establish school wellness policies that covered nutrition education, nutrition standards for school foods, and physical activity. The purpose of this psychometric study was to develop and evaluate the properties of a comprehensive and quantitative coding system to evaluate the quality of these policies. A 96-item coding tool was developed to evaluate seven goal areas: nutrition education, standards for US Department of Agriculture child nutrition programs and school meals, nutrition standards for competitive and other foods and beverages, physical education, physical activity, communication and promotion, and evaluation. Each goal area subscale and the total scale were scored on two dimensions: comprehensiveness and strength. Reliability was assessed by having pairs of researchers from four different states code a sample of 60 polices between July 2007 and July 2008. Goal area subscales were internally reliable (Cronbach's α=.60 to .93). Adequate interrater reliability scores were obtained at each level of scoring: total comprehensiveness and strength scores (intraclass correlation coefficient 0.82), subscale scores (intraclass correlation coefficient 0.70), and individual items (intraclass correlation coefficient 0.72). This coding system provided a reliable method for analyzing and comparing school district wellness policies in single or multistate studies.     

State School Policies and Youth Obesity

The objective of this study was to examine relations between state-level school policies and childhood obesity for youth ages 10–17 years. Secondary analysis of the 2003–2006 School Nutrition Environment State Policy Classification System, 2003–2007 Physical Education Related State Policy Classification System, and 2003 and 2007 National Surveys of Children’s Health was performed. Eleven nutrition and 5 physical education (PE) domains were examined for elementary (ES), middle (MS), and high school (HS) children. Logistic regression models examined the association of policies on obesity prevalence in 2007 as well as change scores for the policy assessments. Scores for 5 of 11 nutrition domains and 4 of 5 PE domains increased between 2003 and 2006–2007. Controlling for individual, family and neighborhood factors, nutrition policies were positively associated with the odds of 2007 obesity in 3 ES and 2 MS domains and negatively associated with 1 HS domain. Adjusted positive associations also were observed between 2 ES and 1 MS PE policy domains and 2007 obesity. Controlling for covariates, nutrition policy change scores showed positive associations between increases in 1 ES and 1MS domain, and negative associations with 1 ES and 1 HS domain and 2007 obesity. PE policy change scores showed positive adjusted associations between increases in 2 ES, 2 MS and 1 HS domains and 2007 obesity. The findings indicate that state-level school health policies are associated with childhood obesity after adjusting for related factors, suggesting that states with higher obesity levels have responded with greater institution of policies.     

Position of the American Dietetic Association: local support for nutrition integrity in schools

It is the position of the American Dietetic Association that the schools and the community have a shared responsibility to provide all students with access to high-quality foods and school-based nutrition services as an integral part of the total education program. Educational goals, including the nutrition goals of the National School Lunch Program and the School Breakfast Program, should be supported and extended through school district wellness policies that create overall school environments that promote access to healthful school meals and physical activity and provide learning experiences that enable students to develop lifelong healthful eating habits. The National School Lunch and School Breakfast Programs are an important source of nutrients for school-age children, and especially for those of low-income status. The American Dietetic Association was actively involved in the 2004 reauthorization of these programs, ensuring access through continued funding, promoting nutrition education and physical activity to combat overweight and prevent chronic disease, and promoting local wellness policies. The standards established for school meal programs result in school meals that provide nutrients that meet dietary guidelines, but standards do not apply to foods and beverages served and sold outside of the school meal. Labeled as competitive foods by the US Department of Agriculture, there is a growing concern that standards should be applied to food in the entire school environment. Legislation has mandated that all school districts that participate in the US Department of Agriculture's Child Nutrition Program develop and implement a local wellness policy by the school year 2006-2007. Resources are available to assist in the development of wellness policies, and dietetics professionals can assist schools in developing policies that meet nutrition integrity standards.     

State school policies and youth obesity

The objective of this study was to examine relations between state-level school policies and childhood obesity for youth ages 10-17 years. Secondary analysis of the 2003-2006 School Nutrition Environment State Policy Classification System, 2003-2007 Physical Education Related State Policy Classification System, and 2003 and 2007 National Surveys of Children's Health was performed. Eleven nutrition and 5 physical education (PE) domains were examined for elementary (ES), middle (MS), and high school (HS) children. Logistic regression models examined the association of policies on obesity prevalence in 2007 as well as change scores for the policy assessments. Scores for 5 of 11 nutrition domains and 4 of 5 PE domains increased between 2003 and 2006-2007. Controlling for individual, family and neighborhood factors, nutrition policies were positively associated with the odds of 2007 obesity in 3 ES and 2 MS domains and negatively associated with 1 HS domain. Adjusted positive associations also were observed between 2 ES and 1 MS PE policy domains and 2007 obesity. Controlling for covariates, nutrition policy change scores showed positive associations between increases in 1 ES and 1MS domain, and negative associations with 1 ES and 1 HS domain and 2007 obesity. PE policy change scores showed positive adjusted associations between increases in 2 ES, 2 MS and 1 HS domains and 2007 obesity. The findings indicate that state-level school health policies are associated with childhood obesity after adjusting for related factors, suggesting that states with higher obesity levels have responded with greater institution of policies.     

School and district wellness councils and availability of low-nutrient, energy-dense vending fare in Minnesota middle and high schools

The Child Nutrition and WIC Reauthorization Act of 2004 required school districts participating in the federal school meals program to establish by the start of the 2006-2007 school year policies that included nutrition guidelines for all foods sold on school campus during the school day and policy development involving key stakeholders. For many schools, policy development was done by wellness councils. This study examined the association between having a wellness council and availability of low-nutrient, energy-dense foods/beverages in school vending machines following enactment of the federal legislation. In 2006-2007, Minnesota middle (n=35) and high (n=54) school principals reported whether their school and district had a wellness council. Trained research staff observed foods/beverages in vending machines accessible to students. Low-nutrient, energy-dense foods/beverages (snacks >3 g fat or >200 calories/serving, and soda, fruit/sport drinks and reduced-fat/whole milk) were grouped into seven categories (eg, high-fat baked goods) and a food score was calculated. Higher scores indicated more low-nutrient, energy-dense vending fare. Multivariate linear regression, adjusted for school characteristics, was used to examine associations between scores and a three-category council variable (district-only; district and school; no council). Among schools, 53% had district-only councils, 38% district and school councils, and 9% had no council. Schools with both a district and school council had a significantly lower mean food score than schools without councils (P=0.03). The potential of wellness councils to impact availability of low-nutrient, energy-dense vending fare is promising. There may be an added benefit to having both a school and district council.     

Establishing a baseline measure of school wellness-related policies implemented in a nationally representative sample of school districts

The Child Nutrition and WIC Reauthorization Act of 2004 required school districts to establish a local school wellness policy by the first day of the 2006-2007 school year. To provide a baseline measure of the extent to which wellness-related policies were implemented in school districts nationwide in 2006, this study analyzed data from the 2006 School Health Policies and Programs Study (SHPPS). SHPPS used a cross-sectional design to measure policies and practices among a nationally representative sample of 538 public school districts. The authors applied a standardized wellness policy coding system to the data by matching each element to relevant questions from SHPPS and calculated the percentage of school districts meeting each element in the coding system. Statistical analyses included calculation of 95% confidence intervals for percentages and mean number of elements met in each area. In 2006, none of the districts met all elements included in the coding system for local wellness policies. In addition, the percentage of districts meeting each element varied widely. On average, districts met the greatest number of elements in the area of nutrition education and the least number of elements in the area of physical activity. By applying a coding system for district policies to an existing dataset, this study used a novel approach to determine areas of strength and weakness in the implementation of local school wellness-related policies in 2006.     

The relationship among state laws, district policies, and elementary school-based measurement of children's body mass index

BACKGROUND: School‐based measurement of children's body mass index (BMI) is a useful tool for tracking childhood obesity rates, and may be an effective intervention strategy for reducing the increasing trends in obesity. This article examines the relationship between state law, district policy, and school‐level BMI measurement practices. METHODS: Data were collected during 3 school years (2006‐2007, 2007‐2008, 2008‐2009) as part of an annual study on health policies and practices in a nationally representative sample of US public elementary schools. Data collected included school‐level data via a mailed questionnaire, and district‐level policies and state laws from publicly available sources. We examined whether state laws and district policies were linked to school‐level BMI measurement, either directly, or via a mediation effect. RESULTS: Schools were most likely to measure student BMI if there was a state law in place (65.0% of schools) than where there was not a state law regarding BMI measurement (38.4% of schools; χ² = 120.91, p < .001). However, school‐level BMI measurement did not differ by whether the district had a relevant policy or not (49.8% vs. 49.2%, ns). These effects held up in multivariate logistic regression models controlling for relevant school‐level covariates (region, race/ethnicity, location, school size, and socioeconomic status). Schools in the south and those with a majority of White students were most likely to measure students' BMI. CONCLUSION: State laws are associated with school‐level BMI measurement, and therefore may be a helpful tool in monitoring and addressing childhood obesity.     

Evaluation of Alabama public school wellness policies and state school mandate implementation

BACKGROUND: This study evaluated wellness policies created by Alabama public school districts and progress made in the implementation of Alabama State Department of Education (ALSDE) school food and nutrition mandates. METHODS: Wellness policies from Alabama public school districts were compared to minimum requirements under the Child Nutrition and Women, Infants, and Children (WIC) Reauthorization Act of 2004. Additionally, data were analyzed from a survey of school district superintendents regarding compliance with ALSDE mandates. Districts were graded based on the percentage of 7 components addressed in wellness policies, and on the percentage of ALSDE mandates implemented. RESULTS: The majority of school districts (71%) were in compliance with all federal wellness policy requirements. An average 6.4 components were addressed, for a mean score of 92%. Mean implementation of ALSDE mandates was 79%; only 7% of districts indicated implementing all of the mandates. No significant differences were found in federal wellness policy or ALSDE mandate compliance scores based on district type, enrollment, percentage of students eligible for free and reduced‐price meals, use of an environmental assessment survey, and use of wellness committee and a nutrition professional during policy development. CONCLUSIONS: The majority of Alabama school districts created school wellness policies with appropriate content. This does not, however, guarantee effective policies. School districts have not done as well implementing ALSDE mandates, demonstrating delay between policy creation and implementation. Future research is needed regarding progress the school districts make in the implementation of school health policy and on factors influencing that progress.     

Factors affecting sugar-sweetened beverage availability in competitive venues of US secondary schools

BACKGROUND: This study explores sugar‐sweetened beverage (SSB) availability in US secondary school competitive venues during the first 3 years following the school wellness policy requirement (2007‐2009). Furthermore, analyses examine associations with school policy and SSB availability. METHODS: Analyses use questionnaire data from 757 middle and 762 high schools in the nationally representative Youth, Education, and Society study to examine soda and non‐soda SSB availability associations with school policy including (1) beverage bottling contracts and related incentives, (2) individuals/organizations responsible for decisions regarding beverages available in vending machines, and (3) school wellness policies and nutrition guidelines. RESULTS: Non‐soda SSBs made up the majority of SSBs in both middle and high schools. Soda was especially likely to be found in vending machines; non‐soda SSBs were widely available across competitive venues. Access to soda decreased significantly over time; however, non‐soda SSB access did not show a similar decrease. School policy allowing beverage supplier contractual involvement (bottling contract incentives and beverage supplier “say” in vending machine beverage choices) was related to increased SSB access. However, the existence of developed nutritional guidelines was associated with lower SSB availability. CONCLUSIONS: Students had high access to SSBs across competitive school venues, with non‐soda SSBs making up the majority of SSB beverage options. Efforts to reduce access to SSBs in US secondary schools should include a focus on reducing both soda and non‐soda SSBs, reducing beverage supplier involvement in school beverage choices, and encouraging the development of targeted nutritional guidelines for all competitive venues.     

The strength of school wellness policies: one state's experience

BACKGROUND: This study examines the results of federal legislation on the content and quality of policies written in 2005-2006 by Utah school districts (n = 30). METHODS: Policies were gathered by phone call requests to school districts or obtained on district Web pages. Content was compared to requirements outlined in the Child Nutrition Reauthorization Act (CNRA) of 2004 and recommendations made by a state coalition of health and education agencies. The strength of the language was assessed (mandate vs recommendation), and characteristics of school districts that adopted strong policies were identified. RESULTS: The majority of Utah school districts (78%) complied with the federal guidelines, and a variety of state recommended nutrition and physical activity policy statements were included. The strength of the language used in the policies revealed that districts were more likely to mandate items already required by other entities or well established in the district. School districts with high participation in free- and reduced-price programs had significantly more mandatory policies (mean = 9.2) versus low (mean = 7.1) and medium enrollment (mean = 4.7). Urban school districts were more likely to indicate mandatory competitive food policies than rural and suburban (mean = 2.3 vs 0.93, 0.83). There were no differences in policy language between school districts based on race or size. CONCLUSIONS: Compliance with the CNRA may be a positive step toward improving the school nutrition and physical activity environment, but it does not ensure a comprehensive or powerful policy. Schools and community partners must continue to work together to strengthen wellness policies and programs.     

School wellness policies: perceptions, barriers, and needs among school leaders and wellness advocates

BACKGROUND: School wellness policies are a key component to the prevention of adolescent obesity. This national research study sought to understand the wellness environment in school districts across the country and to identify challenges districts face and needs they have in order to effectively implement, monitor, and evaluate school wellness policies. The study determined (1) perceptions, barriers, and opportunities regarding the development, implementation, and monitoring/evaluation of school wellness policies among school board members, state school boards association leaders, state public health nutrition directors, and school wellness advocates; (2) the readiness and capacity of survey groups to address nutrition and physical activity policies; (3) the extent to which survey groups collaborate; and (4) the acceptability of wellness tools. METHODS: In 2006, over 2900 individuals participated in online surveys, focus groups, and key informant interviews. School board members represented 1296 school districts across the nation. RESULTS: School board members expressed the highest level of confidence among all survey groups that their district has the capacity to develop, implement, and monitor/ evaluate the wellness policy. The disparities among groups are most notable with regard to perceptions of district capacity to monitor/evaluate the policy. School board members are interested in school wellness policy tools and trainings. CONCLUSIONS: There is an opportunity for state school boards associations, state public health nutrition directors, and school wellness advocates to build their own capacity to provide training and resources to districts on wellness issues, particularly physical education/activity, school-based wellness initiatives, and strategies for implementing and monitoring/evaluating wellness policies.     

Are Physical Education‐Related State Policies and Schools' Physical Education Requirement Related to Children's Physical Activity and Obesity?

BACKGROUND: This study examines whether the extent of states' physical education (PE) requirement policies and the prevalence of schools requiring PE are associated with children's physical activity (PA) and obesity. METHODS: Two cycles (2002–2003 and 2006–2007) of cross‐sectional data with individual‐ and state‐level information were analyzed. Information on states' PE requirement was from the 2003 and 2006 Physical Education‐Related State Policy Classification System, and the prevalence of schools requiring PE was from the 2002 and 2006 School Health Profiles. The individual‐level sample includes 11‐ to 17‐year‐old children from the 2003 (N = 25,251) and 2007 (N = 23,728) National Survey of Children's Health. The associations of states' PE requirement and schools' PE requirement with children's PA and obesity were examined, controlling for individual, family, and state covariates. Variation in the associations by individual and family characteristics was also tested. RESULTS: States' PE requirement was not associated with any outcome. In cycle 1, overall, a 10% increase in the percentage of schools requiring PE was associated with a 28% increase in the number of days having vigorous PA per week. In cycle 2, the association was not significant. However, significant variation in the association by gender in cycle 2 suggests an influence of schools' PE requirement on girls' PA only. No association was found between schools' PE requirement and obesity. CONCLUSIONS: Gaps exist between state PE‐related policies and implementation in schools. However, schools' PE requirement seems to improve children's PA with some gender variation. The association between schools' PE requirement and children's weight is less clear.     

State Agency Support of Weight‐Related School Policy Implementation

BACKGROUND

In this study, we describe state agency strategies to support weight‐related policy implementation in schools, and examine the association among state support, obesity prevalence, and strength of state policies governing school nutrition and physical education.

METHODS

The 2012 School Health Policies and Practices Study describes prevalence of implementation support state agencies provided to schools/districts. Implementation support items were analyzed by weight‐related policy area (eg, advertising, wellness policy) and by type of support (eg, technical assistance). Results were summed to create a total weight‐related policy support score. Linear regression was used to examine associations between policy support and state youth obesity prevalence (2011‐2012 National Survey for Children's Health), overall and stratified by state policy strength (2012 Classification of Laws Associated with School Students).

RESULTS

States provided support most commonly for school meals and wellness policies (89% and 81%, respectively) and least often for after‐school PE (26%). Most states (80%) provided technical assistance. The total weight‐related policy support score had a significant positive association with state‐level youth overweight/obesity prevalence (p = .03).

CONCLUSION

State agencies appear to be responding to their youth obesity prevalence with technical support. Schools and state agencies should work in collaboration to provide a healthy school environment for all students.

     

District Wellness Policy Nutrition Standards Are Associated with Healthier District Food Procurement Practices in the United States

Food procurement policies often exist to require that schools purchase foods with specific nutrient standards. Such policies are increasingly being used with the hope of improving access to healthier foods and beverages. Local wellness policies, required in any school district that participates in Federal Child Nutrition Programs, often contain specific nutrition standards that detail what can be sold to students during the school day. This study investigated the extent to which nutrition standards in wellness policies may be associated with healthier nutrition standards in district-level purchasing specifications. Cross-sectional data from the 2014–2015 school year for 490 school food authorities from 46 states and the District of Columbia were collected as part of the School Nutrition and Meal Cost Study and the National Wellness Policy Study. Survey-adjusted multivariable logistic regression models were computed to examine the association between district wellness policy nutrition standards and corresponding district food purchasing specifications. Results show that having a district wellness policy with corresponding nutrition standards and being in a rural area were associated with district food purchasing specifications for specific nutrients. These findings contribute to the literature to suggest that having a wellness policy with detailed nutrition standards may help to increase access to healthier foods and beverages.     

Schools and Obesity Prevention: Creating School Environments and Policies to Promote Healthy Eating and Physical Activity

Context: Research consistently shows that the majority of American children do not consume diets that meet the recommendations of the Dietary Guidelines for Americans, nor do they achieve adequate levels of daily physical activity. As a result, more children are overweight today than at any other time in U.S. history. Schools offer many opportunities to develop strategies to prevent obesity by creating environments in which children eat healthfully and engage regularly in physical activity. Methods: This article discusses the role of schools in obesity prevention efforts. Current issues in schools' food and physical activity environments are examined, as well as federal, state, and local policies related to food and physical activity standards in schools. The article is organized around four key areas: (1) school food environments and policies, (2) school physical activity environments and policies, (3) school body mass index measurements, and (4) school wellness policies. Recommendations for accelerating change also are addressed. Findings: The article found that (1) competitive foods (foods sold outside of federally reimbursed school meals) are widely available in schools, especially secondary schools. Studies have related the availability of snacks and drinks sold in schools to students' high intake of total calories, soft drinks, total fat and saturated fat, and lower intake of fruits and vegetables; (2) physical activity can be added to the school curriculum without academic consequences and also can offer physical, emotional, and social benefits. Policy leadership has come predominantly from the districts, then the states, and, to a much lesser extent, the federal government; (3) few studies have examined the effectiveness or impact of school‐based BMI measurement programs; and (4) early comparative analyses of local school wellness policies suggest that the strongest policies are found in larger school districts and districts with a greater number of students eligible for a free or reduced‐price lunch. Conclusions: Studies show that schools have been making some progress in improving the school food and physical activity environments but that much more work is needed. Stronger policies are needed to provide healthier meals to students at schools; limit their access to low‐nutrient, energy‐dense foods during the school day; and increase the frequency, intensity, and duration of physical activity at school.     

Peer Reviewed: The Quality of School Wellness Policies and Energy-Balance Behaviors of Adolescent Mothers

Introduction

In this study, we 1) compared the quality of school wellness policies among schools participating in Moms for a Healthy Balance (BALANCE), a school- and home-based weight loss study conducted with postpartum adolescents in 27 states; and 2) assessed the relationship between policy quality with energy-balance behaviors and body mass index z scores of postpartum adolescents.

Methods

As a part of BALANCE, we collected data on high-calorie food and beverage consumption, minutes spent walking, and height and weight for 647 participants. The School Wellness Policy Coding Tool was used to assess the strength and comprehensiveness of school district wellness policies from 251 schools attended by participating adolescent mothers.

Results

Schools averaged low scores for wellness policy comprehensiveness and strength. When compared with participants in schools with the lowest policy comprehensiveness scores, adolescent mothers in schools with the highest scores reported consuming significantly fewer daily calories from sweetened beverages while reporting higher consumption of water (P = .04 and P = .01, respectively). School wellness policy strength was associated with lower BMI z scores among adolescent mothers (P = .01).

Conclusion

School wellness policies associated with BALANCE may be limited in their ability to promote a healthy school environment. Future studies are needed to evaluate the effect of the strength and comprehensiveness of policy language on energy balance in high-risk postpartum adolescents. Evidence from this work can provide additional guidance to federal or state government in mandating not only policy content, but also systematic evaluation.
