Association between Nutrition Policies and Student Body Mass Index

In response to concerns about childhood obesity, many US states have implemented policies to limit the sale of unhealthy foods and beverages (e.g., snacks, desserts, and sugary drinks) sold in competition with school meal programs (i.e., competitive foods) in order to improve the nutritional environment of schools and support student health. This study measured state-level competitive food and beverage policies that require foods and beverages sold in à la carte lines, vending machines, and school stores to meet strong nutrition standards and tested the hypothesis that students living in states with stronger laws would have lower body mass index (BMI)-for-age percentiles. BMI data from a national sample of 1625 students attending 284 schools from the School Nutrition and Meal Cost Study were linked to state laws coded as part of the National Wellness Policy Study. A survey-adjusted linear regression model accounting for student and school-level characteristics showed that stronger state nutrition policies were associated with lower student BMI scores (coefficient: −0.06, 95% CI: −0.12, −0.00). Additional models indicated that stronger state policies were significantly associated with fewer unhealthy foods and beverages available in schools. These findings suggest that strong regulations on competitive foods and beverages may lead to improvements in the nutritional quality of the school environment and student BMI. Thus, current federal standards regulating snacks in US schools (i.e., Smart Snacks) are an important element of a comprehensive strategy to improve the school nutrition environment and reduce rates of childhood obesity.     

Competitive foods and beverages available for purchase in secondary schools--selected sites, United States, 2006

Schools are in a unique position to help improve youth dietary behaviors and prevent and reduce obesity. In most schools, foods and beverages are made available to students through the U.S. Department of Agriculture (USDA) school meal programs and the sale of competitive foods, which are any foods and beverages sold at a school separately from the USDA school meal programs. Foods and beverages sold through the USDA school meal programs must meet federal nutrition requirements. Competitive foods are not subject to any federal nutrition standards unless they are sold inside the food service area during mealtimes. A 2007 Institute of Medicine (IOM) report concluded that schools should limit the availability of less nutritious competitive foods or include more nutritious foods and beverages if they make competitive foods available. To identify the types of competitive foods and beverages available for purchase from vending machines or at school stores, canteens, or snack bars, CDC analyzed data from the 2006 School Health Profiles for public secondary schools in 36 states and 12 large urban school districts. CDC also compared 2004 and 2006 data among 24 states and nine large urban school districts. This report summarizes the results of these analyses, which indicated that, from 2004 to 2006, the median percentage of secondary schools across states allowing students to purchase chocolate candy and salty snacks that are not low in fat decreased; however, in 2006, secondary schools still offered less nutritious foods and beverages that compete with school meals. School and public health officials should work together with families to provide foods and beverages at school that follow the IOM recommendations.     

Association and diffusion of nutrition and physical activity policies on the state and district level

BACKGROUND: School district wellness policies designed to reduce obesity and promote student health and well‐being often lack specific requirements or any mandate that schools comply with the policy. Researchers, educators, and policymakers have called for states to take an active role in shaping district policies. The objective of this study was to determine if states with strong school‐based nutrition and physical activity (PA)‐related policies have stronger district wellness policies, and explore the direction of policy diffusion between states and districts. METHODS: State policies and nationally representative samples of district policies for the 2006–2007 and 2008–2009 school years were obtained across 5 domains—competitive foods, school meals, nutrition education, physical education (PE), and PA—and were classified as “strong” or “weak,” based on policy language, in each grade level (elementary, middle, high). Linear models estimated the cross‐sectional and longitudinal associations between state and district policies. RESULTS: In 2006–2007 and 2008–2009, district elementary school competitive food policies were stronger in states with strong policies. For policies governing competitive foods in high schools and school meals at all grade levels, mean district policy strength increased from 2006–2007 to 2008–2009 in states with strong 2006–2007 policies. States that strengthened their PE policies from 2006–2007 to 2008–2009 saw an increase in mean district PE policy strength. Across all domains, states that had weak 2006–2007 policies and made no changes saw little increase in district policy strength. CONCLUSION: District competitive food, school meal, and PE policies are stronger in states that have developed strong policies in these domains.     

Change in School Nutrition–Related Laws From 2003 to 2008: Evidence From the School Nutrition–Environment State Policy Classification System

Objectives. We examined state laws affecting the school food environment and changes in these laws between 2003 to 2008.Methods. We used the Westlaw legal database to identify state-codified laws, with scoring derived from the updated School Nutrition–Environment State Policy Classification System, obtained from the Classification of Laws Associated With School Students Web site.Results. States significantly changed their school nutrition laws from 2003 to 2008, and many increased the stringency of the laws targeting competitive foods (snacks and entrées sold in competition with the school meal) and beverages sold in school and for in-school fundraising. Many states enacted laws that mandated the establishment of a coordinating or advisory wellness team or council. Stronger laws were enacted for elementary grades. We found tremendous variability in the strength of the laws and plenty of room for improvement.Conclusions. State law governing school nutrition policies significantly changed from 2003 to 2008, primarily affecting the competitive food environment in schools. The extent to which changes in school nutrition laws will lead to desired health outcomes is an area for additional research.Childhood obesity is on the rise in many industrialized nations, and prevalence in the United States has reached alarming proportions.1 Obesity is a complex and multifactorial problem that requires population-based preventive solutions.2,3 Focusing on the school food environment is considered to be an important starting point because almost all children attend school, and they consume about one third of their caloric requirements there.4 In the past decade, ideas about school nutrition policies to optimize the nutritional environment of schools have undergone a drastic shift.In the intervention literature, modification of the school nutrition environment has been associated with student eating behaviors, but its influence on obesity is unclear.5–7 Evidence suggests that food and beverage availability,8–12 quality of the food offered in schools,13,14 length of the lunch period,15 and pricing and marketing practices16–19 in schools have had an impact on student eating behaviors (total intake, fat consumption, and food preferences). In cross-sectional studies, the school nutrition environment has been linked with children''s eating behaviors and body mass index (BMI).20,21 In light of this evidence, it is not surprising that policymakers are resorting to strategies to modify the school nutrition environment to ultimately affect childhood obesity.As school nutrition policies are increasingly being used to curb the rise in childhood obesity, support for such policies in the scientific literature is emerging.22–29 State laws and district policies have been found to influence the school nutrition environment: studies reveal an inverse association between school nutrition policies and the availability of less healthy foods and beverages at school.22–29 For example, Mendoza et al. noted significant improvements in the energy density of the foods and beverages consumed at lunchtime among sixth and eighth graders after the Texas nutrition policy was implemented.28 In addition, school nutrition policies have been favorably associated with the prevalence of overweight and obesity in children; some studies report that the increase in prevalence has been halted as a result of these policies.16,26,30–32 When researchers have evaluated the influence of both state and district school nutrition policies, state laws have been found to be more important in influencing behaviors and BMI.33 Because state laws and policies will likely have wider influence on the school environment, it is essential to monitor the enactment of laws and the strength of these laws across states.We aimed to (1) update the status of state laws for school nutrition–related policies with the revised School Nutrition–Environment State Policy Classification System (SNESPCS), which was previously published in 2007,34 and (2) examine whether state laws focused on school nutrition–related policies changed from 2003 to 2008. Improvements were expected during this period because the US Congress mandated significant improvement in the school environment as part of the Child Nutrition and Women, Infants, and Children Reauthorization Act of 2004.35 Specifically, Congress required all school districts that participate in the National School Lunch Program and other federal child nutrition programs to develop and implement a local school wellness policy by the 2006 to 2007 school year that includes, but is not limited to

1. goals for nutrition education,
2. guidelines for food and beverage availability at school,
3. assurance that federal regulations for the reimbursable school meal are followed,
4. a plan for assessing implementation of the policy as well as designation of staff responsible for the implementation of the wellness policy, and
5. involvement of the school community in the development of the policy.

Although the wellness policy was required at the district level, many states enacted laws around this time related to the school nutrition environment to provide a framework for districts to follow. Our previous assessment of state laws in this area indicated wide variations by grade,34 so we examined changes by elementary, middle, and high school levels.     

Reducing Calories and Added Sugars by Improving Children's Beverage Choices

Because childhood obesity is such a threat to the physical, mental, and social health of youth, there is a great need to identify effective strategies to reduce its prevalence. The objective of this study was to estimate the mean calories from added sugars that are saved by switching sugar-sweetened beverages (including soda, fruit-flavored drinks, and sport drinks) and flavored milks consumed to unflavored low-fat milk (<1% fat) at meals and water between meals. Simulation analyses used 24-hour dietary recall data from the third School Nutrition Dietary Assessment Study (n=2,314), a 2005 national cross-sectional study of schools and students participating in the National School Lunch Program, to estimate changes in mean calories from added sugars both at and away from school. Overall, these changes translated to a mean of 205 calories or a 10% savings in energy intake across all students (8% among children in elementary school and 11% in middle and high schools). Eighty percent of the daily savings were attributed to beverages consumed away from school, with results consistent across school level, sex, race/ethnicity, and weight status. Children's consumption of sugar-sweetened beverages at home contributed the greatest share of empty calories from added sugars. Such findings indicate that parental education should focus on the importance of reducing or eliminating sugar-sweetened beverages served at home. This conclusion has implications for improving children's food and beverage environments for food and nutrition educators and practitioners, other health care professionals, policy makers, researchers, and parents.     

Alliance for a Healthier Generation's Competitive Beverage and Food Guidelines: Do Elementary School Administrators Know About Them and Do They Report Implementing Them?

BACKGROUND: The availability of competitive foods in schools is a modifiable factor in efforts to prevent childhood obesity. The Alliance for a Healthier Generation launched the Healthy Schools Program in 2006 to encourage schools to create healthier food environments, including the adoption of nutritional guidelines for competitive beverages and foods. This study examines nationwide awareness and implementation of the guidelines in US public elementary schools. METHODS: Data were collected from a nationally representative sample of elementary schools using mail-back surveys in 2006-2007, 2007-2008, 2008-2009, and 2009-2010. RESULTS: From 2006-2007 to 2009-2010, awareness of the Alliance's beverage guidelines increased from 35.0% to 51.8% among school administrators (p < .01); awareness of the food guidelines increased from 29.4% to 40.2% (p < .01). By 2009-2010, almost one third of the schools that sold competitive beverages and foods reported having implemented or being in the process of implementing the guidelines. Implementation was higher among schools from Southern states. Schools with a majority of Black or Latino students were less likely to implement the guidelines. CONCLUSIONS: Awareness and implementation of the Alliance's beverage and food guidelines has significantly increased since the 2006-2007 school year, indicating successful diffusion of the guidelines. However, many administrators at schools who sold competitive products were not aware of the guidelines, indicating a need for continued efforts. In addition, lower implementation among schools serving minority students suggests that the Alliance's targeted efforts to provide intensive technical assistance to such schools is warranted and necessary.     

Does the sale of sweetened beverages at school affect children’s weight?

In response to the increase in children's weight in recent decades, many states, school districts, and schools in the United States have limited or eliminated the sale of sweetened beverages at school. These policies are promoted for their potential to reduce childhood overweight and obesity, but their effectiveness has not been evaluated. Using a large nationally representative longitudinal dataset, the Early Childhood Longitudinal Study-Kindergarten (ECLS-K), this study explores the relationship between children's access to sweetened beverages at school in 5th and 8th grade, their purchases and total consumption of these beverages, and their weight. We find almost no evidence that availability of sweetened beverages for sale at school leads to heavier weight or greater risk of overweight or obesity among children. We also find limited evidence that availability of sweetened beverages for sale at school leads to higher total consumption of these beverages.     

Food sales outlets, food availability, and the extent of nutrition policy implementation in schools in British Columbia

BACKGROUND: The purpose of this study was to determine the number and types of different food sales outlets, the types of foods offered for sale in all school food outlets, and the extent of nutrition policy implementation in schools in British Columbia. We also directly measured the number and types of snack foods available for sale in each vending machine at each school. METHODS: Based on a thorough literature review and guided by an expert panel of nutritionists, we developed an instrument to measure the quantity and types of foods offered for sale in vending machines, the types of food for sale in all school food outlets, and the extent of nutrition policy development. RESULTS: The survey response rate was approximately 70%. Approximately 60% of surveyed schools had a permanent food sales outlet. Snack and beverage vending machines were most common in secondary schools, while tuck shops and food-based fundraisers were more common in elementary schools. While few snack vending machines were present in elementary schools, tuck shops stocked items commonly found in snack machines. Approximately 25% of schools had a formal group responsible for nutrition. These schools were more likely to have nutrition policies in place. CONCLUSION: "Junk" foods were widely available in elementary, middle, and secondary schools through a variety of outlets. Although snack machines are virtually absent in elementary schools, tuck shops and school fundraisers sell foods usually found in snack machines, largely cancelling the positive effect of the absence of snack machines in these schools. Schools with a group responsible for nutrition appear to have a positive impact on nutrition policy implementation.     

Food and Beverage Environment Analysis and Monitoring System: A Reliability Study in the School Food and Beverage Environment

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.     

Impact of Connecticut Legislation Incentivizing Elimination of Unhealthy Competitive Foods on National School Lunch Program Participation

Objectives. We analyzed the impact of Connecticut legislation incentivizing voluntary school district–level elimination of unhealthy competitive foods on National School Lunch Program (NSLP) participation.Methods. We analyzed data on free, reduced, and paid participation in the NSLP from 904 schools within 154 Connecticut school districts from the 2004–2005 to the 2009–2010 school year, resulting in 5064 observations of annual school-level meal participation. We used multilevel regression modeling techniques to estimate the impact of the state competitive food legislation on the count of NSLP lunches served per student in each school.Results. Overall, the state statute was associated with an increase in school lunch participation. We observed increases between 7% and 23% for middle- and high-school meal programs, and a slight decrease of 2.5% for the elementary school free meal eligibility category, leading to an estimated revenue increase of roughly $30 000 for an average school district per school year.Conclusions. This study provides support for national implementation of proposed rigorous competitive food standards that can improve the health of students while supporting local school district finances.Federal meal programs in the United States serve more than 30 million students every day, providing an unparalleled opportunity to improve the diet of the nation’s youths.1 Recent changes to school meal program regulations will substantially improve the nutritional quality of meals that have already succeeded at preventing childhood nutritional deficiencies in the United States.2–4 Public health efforts to reduce childhood obesity rates and improve diet quality in the United States have increasingly focused on improving the food environment in schools.5–7The sale of foods in schools outside the school meal programs, known as competitive foods, has been consistently linked with unhealthy diet and, in some but not all studies,8 with increased risk of obesity.9 Energy-dense, nutrient-poor competitive foods and beverages are widely available in US schools and are regularly consumed by children.10–13 A number of local school district and statewide policy changes reducing or eliminating the sale of unhealthy competitive food and beverages at school have been shown to improve dietary outcomes, including reduced sugar-sweetened beverage consumption and increased consumption of fruits and vegetables.14–16 Sanchez-Vaznaugh et al. reported that removing unhealthy competitive foods may be linked to a lower incidence of overweight in children in California.17 Taber et al. reported findings based on the Early Childhood Longitudinal Study–Kindergarten showing that adolescents in states with strong competitive food standards from 2003 to 2006 gained 0.44 body mass index (BMI; defined as weight in kilograms divided by the square of height in meters) units less than adolescents in states without such standards.18Despite the success of some state and local policies, national policy efforts have so far failed to sufficiently address the negative impact of the sale of unhealthy competitive foods on children’s health. The Child Nutrition and WIC Reauthorization Act of 2004 required all school districts participating in the National School Lunch Program (NSLP) to develop wellness policies that include nutrition guidelines for all foods available at schools by the 2006–2007 school year.19 However, the legislation did not require districts to implement specific competitive food policies.5 A review of a nationally representative sample of wellness policies and related regulations from 2006–2007 up to 2008–2009 found that, although some districts have implemented strong policies, in general, rules governing competitive food sales were weak or nonexistent.20In response to concerns about the role of both the school meal programs and competitive foods in addressing the obesity epidemic, Congress passed The Healthy, Hunger-Free Kids Act of 2010.21 The act required the US Department of Agriculture (USDA) to update the nutrition standards for the NSLP and the School Breakfast Program while providing a performance-based increase in reimbursement rate for lunches. The bill also for the first time gave the USDA authority to set nutrition standards for competitive foods sold throughout the school day.21 Congress instructed the USDA to develop nutrition standards for competitive foods that align with the current Dietary Guidelines for Americans22 while giving consideration to practical application of the standards. The USDA is currently developing competitive food standards with the goal of releasing final regulations in 2013.Reactions to the USDA’s revised nutrition standards for the school meal program suggest that the USDA may face strong opposition to nutritionally rigorous competitive food standards.23,24 In addition to objections raised by food industry associations, the School Nutrition Association, which represents school food service professionals, commented to the USDA that improving the health quality of the school meals may reduce participation in the program if students instead purchase competitive foods or bring food from outside school.25However, creating rigorous new competitive food nutrition standards could support simultaneous implementation of improved meal program standards by removing unhealthy yet attractive alternatives to the meal program from school environments. A number of studies have found that reducing availability of unhealthy competitive foods results in increased meal program participation and limited impact on overall food service revenue.26,27 On the basis of a systematic review that identified 7 studies that assessed the relationship between nutrition standards and school revenue, Wharton et al. concluded that fears of net negative financial impacts of improved nutrition standards are unfounded and that increased participation in NSLP may compensate for lost revenue from lower competitive food sales.27 However, because there is a relatively limited evidence base, additional evidence showing that implementing stronger competitive food standards across a broad range of schools can increase school meal participation would support ongoing USDA efforts to implement rigorous national competitive food and school meal nutrition standards.Since 2006, Connecticut’s Healthy Food Certification (HFC) has offered school districts in the state a monetary incentive to comply with stringent competitive food nutrition standards that are updated annually.28 The standards, which are based on the Dietary Guidelines for Americans, apply to all foods sold at school at all times. Exceptions can be granted by local school boards for food sold during events held outside the regular school day. Districts must annually file compliance forms with the Connecticut State Department of Education (CSDE), which reviews nutrition information for all foods sold in each district and conducts site visits in selected participating districts to ensure compliance. Districts that choose to comply with the voluntary standards are paid an additional 10 cents per lunch by the state, based on the total number of reimbursable lunches (paid, free, and reduced) served in the district in the previous school year. Previous research based on the program’s first year of implementation found that districts participating in HFC substantially reduced the availability of unhealthy competitive food and increased paid school meal participation in middle schools.29This study extends the initial evaluation of the program, and analyzes the impact of district participation in HFC on student participation in free, reduced, and paid lunches by using statewide school meal participation data from the 2004–2005 to 2009–2010 school years. It was hypothesized that district participation in HFC is positively related to student participation in the NSLP.     

Nutrition services and foods and beverages available at school: results from the School Health Policies and Programs Study 2006

BACKGROUND: Schools are in a unique position to promote healthy dietary behaviors and help ensure appropriate nutrient intake. This article describes the characteristics of both school nutrition services and the foods and beverages sold outside of the school meals program in the United States, including state- and district-level policies and school practices. METHODS: The Centers for Disease Control and Prevention conducts the School Health Policies and Programs Study every 6 years. In 2006, computer-assisted telephone interviews or self-administered mail questionnaires were completed by state education agency personnel in all 50 states plus the District of Columbia and among a nationally representative sample of school districts (n=445). Computer-assisted personal interviews were conducted with personnel in a nationally representative sample of elementary, middle, and high schools (n=944). RESULTS: Few states required schools to restrict the availability of deep-fried foods, to prohibit the sale of foods that have low nutrient density in certain venues, or to make healthful beverages available when beverages were offered. While many schools sold healthful foods and beverages outside of the school nutrition services program, many also sold items high in fat, sodium, and added sugars. CONCLUSIONS: Nutrition services program practices in many schools continue to need improvement. Districts and schools should implement more food preparation practices that reduce the total fat, saturated fat, sodium, and added sugar content of school meals. In addition, opportunities to eat and drink at school should be used to encourage greater daily consumption of fruits, vegetables, whole grains, and nonfat or low-fat dairy products.     

Competitive foods and beverages available for purchase in secondary schools--selected sites, United States, 2004

The percentage of overweight youths aged 12-19 years in the United States more than tripled from 5% during 1976-1980 to 16% during 1999-2002. Overweight youths are at increased risk for cardiovascular consequences and other serious physical and psychosocial health problems. Because most youths are enrolled in school, the school nutrition environment is integral to any strategy to improve dietary behavior and reduce overweight among youths. In most schools, the nutrition environment has two components: the U.S. Department of Agriculture (USDA) school meals program and the sale of competitive foods. USDA defines competitive foods as those foods and beverages, regardless of nutritional value, sold at a school separate from the USDA school meals program. To identify the types of competitive foods and beverages available for purchase from school vending machines or at school stores, canteens, or snack bars, CDC analyzed data from the 2004 School Health Profiles for public secondary schools in 27 states and 11 large urban school districts. This report summarizes the results of that analysis, which indicated that, in 2004, the majority of secondary schools (median across states: 89.5%; median across large urban school districts: 81.5%) allowed students to purchase snack foods or beverages from vending machines or at the school store, canteen, or snack bar. In addition, the percentage of schools offering certain types of snack foods and beverages varied across states and large urban school districts. Although the majority of schools offered some nutritious foods and beverages in these settings, the majority of schools also offered less nutritious choices. Educators, families, and school and public health officials should work together to provide school nutrition environments that will help improve dietary behavior and reduce overweight among youths.

Disparities in Consumption of Sugar-Sweetened and Other Beverages by Race/Ethnicity and Obesity Status among United States Schoolchildren

ObjectiveIdentify disparities by race/ethnicity and obesity status in the consumption of sugar-sweetened beverages (SSBs) and other beverages among United States schoolchildren to help tailor interventions to reduce childhood obesity.DesignSecondary data analysis using beverage intake data from 24-hour dietary recalls and measured height and weight from the third School Nutrition Dietary Assessment Study, a 2004-2005 nationally representative sample of school-aged children and schools.SettingSchools participating in the National School Lunch Program (n = 287).ParticipantsChildren in grades 1-12 with a completed 24-hour dietary recall (n = 2,314).Main Outcome Measure(s)Percentage of children consuming beverages in 8 beverage categories by school level and consumption location.AnalysisTwo-tailed t tests to determine significant differences (P < .05) between the proportions of children consuming beverages by race/ethnicity and weight status.ResultsBeverage consumption patterns did not substantially differ across weight status groups, but they differed by race/ethnicity in the home. Non-Hispanic black elementary schoolchildren consumed nonsoda SSBs more often and unflavored, low-fat milk less often at home than non-Hispanic white schoolchildren.Conclusions and ImplicationsHigher consumption of SSBs coupled with a lower consumption of milk is disproportionately affecting non-Hispanic black schoolchildren. Targeted interventions by racial/ethnic group are needed to promote more healthful beverage choices among schoolchildren, particularly at home.     

Nutrition education in India—Impact on knowledge,behavior, and health status of students

We conducted a baseline survey in 2900 households drawn from 2 slums and 6 community development blocks (see note)—that is, 2 community development blocks from each of the 3 districts selected out of the 15 districts of Tamil Nadu (which is one of the 22 states [provinces] in India). Based on the findings of the survey, we identified priority concepts in nutrition and health education, and environmental sanitation. We incorporated these concepts into the existing elementary school curriculum and developed suitable instructional materials. We then provided a 5-day orientation for all of the 6000 teachers from the 660 elementary schools in the selected 6 community development blocks and 2 slums. The orientation training was carried out by instructors who had bachelor's degrees in education and master's degrees in nutrition. The trained elementary school teachers, in turn, taught the nutrition and health, and environmental sanitation lessons to their classes. We evaluated the knowledge of the children and teachers; the practices of the mothers with regard to food, health, and hygiene; and the anthropometric and clinical status of the children. For purposes of this study we limited our evaluations of the school children to students in classes 3–5 (equivalent to grades 3–5 in the U.S.). The encouraging results from this study pave the way for further expansion of the program throughout the state and in other states of the Indian Union Republic.     

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.

     

The interplay of public health law and industry self-regulation: the case of sugar-sweetened beverage sales in schools

It is increasingly recognized that sugar-sweetened beverage consumption contributes to childhood obesity. Most states have adopted laws that regulate the availability of sugar-sweetened beverages in school settings. However, such policies have encountered resistance from consumer and parent groups, as well as the beverage industry. The beverage industry's recent adoption of voluntary guidelines, which call for the curtailment of sugar-sweetened beverage sales in schools, raises the question, Is further policy intervention in this area needed, and if so, what form should it take? We examine the interplay of public and private regulation of sugar-sweetened beverage sales in schools, by drawing on a 50-state legal and regulatory analysis and a review of industry self-regulation initiatives.
