Exposure to a comprehensive school intervention increases vegetable consumption.

PURPOSE The current epidemic of childhood overweight has launched a variety of school-based efforts to address the issue. This study reports on the first 2 years of a 3-year evaluation of one school districts comprehensive intervention to transform school foodservices and dining experiences, offer cooking and gardening programs, and integrate nutrition and food systems concepts into the academic curriculum. METHODS This 3-year prospective study enrolled 327 4th and 5th graders in a mid-sized school district in California, and followed them into middle school. Intervention exposure was determined through interviews with school staff and student surveys. Student knowledge and attitudes were assessed annually by questionnaire, and student behavior was assessed annually by 3-day food diary. Household information was gathered by parent questionnaire. Changes in knowledge, attitudes, and behavior were compared by level of intervention exposure using analysis of covariance; pairwise differences were evaluated using Bonferronis test at a procedure-wise error rate of 5%. RESULTS After controlling for family sociodemographic background, students most exposed to the intervention increased their consumption of fruits and vegetables by nearly 0.5 cups (one standard serving), whereas students least exposed decreased their consumption by 0.3 cups (p < .05). Students most exposed to the programming also showed a significantly greater increase in preference for fruit and green leafy vegetables, compared to students least exposed to the programming (p < .05). CONCLUSIONS Future research is needed to better understand the relative importance of the different components of such a program, and their cost-benefits as well as health impacts.

Perceptions of tap water and school water fountains and association with intake of plain water and sugar-sweetened beverages.

BACKGROUND Little is known regarding youth perceptions of tap water and school water fountains and how these relate to water and sugar-sweetened beverage (SSB) intake. METHODS We used national 2010 YouthStyles data to assess perceptions of tap water and school water fountains and associations with water and SSB intake. RESULTS Nearly 1 in 5 participants disagreed their tap water was safe and nearly 2 in 5 disagreed school water fountains were clean and safe. Perceived tap water risk was more prevalent among non-Hispanic (NH) Blacks (26.4%) and Hispanics (28.3%) compared with NH Whites (14.7%, p < .001) and more prevalent among lower-income youth. Negative water fountain perceptions were more common among high school-aged youth. Perceived tap water risk was not associated with SSB intake (odds ratio [OR] = 1.0, 95% confidence interval [CI]: 0.6, 1.5) or water intake (OR = 1.4, 95% CI: 0.9, 2.1). Negative water fountain perceptions were associated with SSB intake only among Hispanics (race/ethnicity interaction p < .001; OR = 2.9, 95% CI: 1.3, 6.6) but were not associated with water intake. CONCLUSION Negative perceptions of tap water and water fountains among youth are common and should be considered in efforts to provide water in schools.

Trends in Beverage Consumption Among High School Students — United States, 2007–2015

Beverages play an important role in the diets of adolescents because they help to maintain hydration and can provide important nutrients, such as calcium, vitamin D, and vitamin C (1). However, some beverages, such as sugar-sweetened beverages (SSBs) (e.g., soda or pop), provide calories with no beneficial nutrients. Beverage consumption patterns among American youth have changed over time; however, little is known about differences in consumption of various beverages by demographic characteristics such as grade in school, free/reduced price lunch eligibility, and race/ethnicity (2). CDC analyzed data from the 2007-2015 national Youth Risk Behavior Surveys (YRBS) to assess whether the prevalence of drinking non-diet soda or pop (soda), milk, and 100% fruit juice (juice) has significantly changed over time among U.S. high school students. During 2007-2015, daily soda consumption decreased significantly from 33.8% to 20.5%. During 2007-2011, daily milk and juice consumption did not significantly change, but during 2011-2015 daily milk and juice consumption decreased from 44.3% to 37.4% and from 27.2% to 21.6%, respectively. Although a decrease in daily soda consumption is a positive change, soda consumption remains high. Although there is not a specific recommendation for sugar-sweetened beverage consumption, the Dietary Guidelines for Americans 2015-2020 recommend that U.S. residents reduce sugar-sweetened beverage and sweet consumption to reduce intake of added sugars to less than 10% of calories per day. The Dietary Guidelines for Americans 2015-2020 recommend that persons choose beverages with no added sugars, such as water, in place of sugar-sweetened beverages, as one strategy for achieving the added sugars recommendation. Adolescents might need additional support in choosing more healthful beverages, such as low-fat milk, in place of SSBs.

The Association of Meal Practices and Other Dietary Correlates With Dietary Intake Among High School Students in the United States, 2010

Purpose. To examine behavioral and environmental factors that may be related to dietary behaviors among U.S. high school students. Design. Data were obtained from the 2010 National Youth Physical Activity and Nutrition Study, a cross-sectional study. Setting. The study was school-based. Subjects. Study subjects were a nationally representative sample of students in grades 9 to 12 (n = 11,458). Measures. Variables of interest included meal practices, in-home snack availability, and intakes of healthful foods/beverages (fruits, vegetables, water, and milk) and less healthful foods/beverages (fried potatoes, pizza, and sugar-sweetened beverages). Analysis. Sex-stratified logistic regression models were used to examine associations of meal practices and snack availability with dietary intake. Odds ratios (ORs) were adjusted for race/ethnicity and grade. Results. Eating breakfast daily, frequent family dinners, and bringing lunch from home were associated with higher odds of consuming at least three healthful foods or beverages. High fast-food intake was associated with lower odds of healthful dietary intake and higher odds of sugar-sweetened beverage intake (female OR = 3.73, male OR = 4.60). Students who mostly/always had fruits and vegetables available at home had increased odds of fruits (female OR = 3.04, male OR = 2.24), vegetables (female OR = 2.12, male OR = 1.65), water (female OR = 1.82, male OR = 1.85), and milk intake (female OR = 1.45, male OR = 1.64). Conclusion. Encouraging daily breakfast consumption, frequent family dinners, and fruit and vegetable availability at home may lead to higher intakes of healthful foods among high school students.

Preventing Obesity through Schools

This paper describes highlights from the Weight of the Nation 2012 Schools Track. Included is a summary of 16 presentations. Presenters shared key actions for obesity prevention through schools. The information provided at the Weight of the Nation can help school health practitioners access tools, apply evidence-based strategies, and model real-world examples to successfully start obesity prevention initiatives in their jurisdiction.

Health-Related Behaviors and Academic Achievement Among High School Students — United States, 2015

Studies have shown links between educational outcomes such as letter grades, test scores, or other measures of academic achievement, and health-related behaviors (1-4). However, as reported in a 2013 systematic review, many of these studies have used samples that are not nationally representative, and quite a few studies are now at least 2 decades old (1). To update the relevant data, CDC analyzed results from the 2015 national Youth Risk Behavior Survey (YRBS), a biennial, cross-sectional, school-based survey measuring health-related behaviors among U.S. students in grades 9-12. Analyses assessed relationships between academic achievement (i.e., self-reported letter grades in school) and 30 health-related behaviors (categorized as dietary behaviors, physical activity, sedentary behaviors, substance use, sexual risk behaviors, violence-related behaviors, and suicide-related behaviors) that contribute to leading causes of morbidity and mortality among adolescents in the United States (5). Logistic regression models controlling for sex, race/ethnicity, and grade in school found that students who earned mostly As, mostly Bs, or mostly Cs had statistically significantly higher prevalence estimates for most protective health-related behaviors and significantly lower prevalence estimates for most health-related risk behaviors than did students with mostly Ds/Fs. These findings highlight the link between health-related behaviors and education outcomes, suggesting that education and public health professionals can find their respective education and health improvement goals to be mutually beneficial. Education and public health professionals might benefit from collaborating to achieve both improved education and health outcomes for youths.

Early Outcomes of State Public Health Actions’ School Nutrition Strategies

Introduction Since 2013, the State Public Health Actions to Prevent and Control Diabetes, Heart Disease, Obesity and Associated Risk Factors and Promote School Health (State Public Health Actions) program has been implemented to support and reinforce healthy choices and healthy behaviors among the US population. The Centers for Disease Control and Prevention’s Division of Population Health’s School Health Branch has been a critical component, ensuring that state health departments support schools in adopting nutrition standards and creating a supportive nutrition environment. The objective of this article was to describe early outcomes of the school nutrition strategies of State Public Health Actions. Methods We examined the extent of progress for short-term performance measures and for school nutrition evaluation questions, using data secured from 51 grantees through the performance measures database and state evaluation reports. Results During the first 4 years of the cooperative agreement, grantees demonstrated significant progress compared with year 2 for school nutrition performance measures. Collectively, grantees provided professional development and technical assistance to staff in 7,672 local education agencies and reached more than 29 million students. Success was also noted for several nutrition practices in schools. Conclusion These early outcomes suggest that State Public Health Actions has had a positive impact on the nutrition environment of US schools. Systematically addressing areas for improvement could further expand the reach of these efforts during the remainder of the cooperative agreement.

The Relationship Between State Policies for Competitive Foods and School Nutrition Practices in the United States

Introduction Most students in grades kindergarten through 12 have access to foods and beverages during the school day outside the federal school meal programs, which are called competitive foods. At the time of this study, competitive foods were subject to minimal federal nutrition standards, but states could implement additional standards. Our analysis examined the association between school nutrition practices and alignment of state policies with Institute of Medicine recommendations (IOM Standards). Methods For this analysis we used data from the Centers for Disease Control and Prevention’s (CDC’s) report, Competitive Foods and Beverages in US Schools: A State Policy Analysis and CDC’s 2010 School Health Profiles (Profiles) survey to examine descriptive associations between state policies for competitive foods and school nutrition practices. Results Access to chocolate candy, soda pop, sports drinks, and caffeinated foods or beverages was lower in schools in states with policies more closely aligned with IOM Standards. No association was found for access to fruits or nonfried vegetables. Conclusion Schools in states with policies more closely aligned with the IOM Standards reported reduced access to less healthful competitive foods. Encouraging more schools to follow these standards will help create healthier school environments and may help promote healthy eating among US children.

State-Level Guidance and District-Level Policies and Practices for Food Marketing in US School Districts

State agencies play a critical role in providing school districts with guidance and technical assistance on school nutrition issues, including food and beverage marketing practices. We examined associations between state-level guidance and the policies and practices in school districts regarding food and beverage marketing and promotion. State policy guidance was positively associated with districts prohibiting advertisements for junk food or fast food restaurants on school property. Technical assistance from states was negatively associated with 2 district practices to restrict marketing of unhealthy foods and beverages, but positively associated with 1 practice to promote healthy options. These findings may help inform the guidance that states provide to school districts and help identify which districts may need additional assistance to address marketing and promotion practices.

Coordinated Approaches to Strengthen State and Local Public Health Actions to Prevent Obesity, Diabetes, and Heart Disease and Stroke

Chronic diseases, including heart disease, stroke, cancer, diabetes, and obesity, are the leading causes of death in the United States and account for most of the nation’s health care costs (1). Heart disease is the leading cause of death among men and women in the United States, accounting for 1 of every 4 deaths (1). Approximately 140,000 Americans die each year from stroke, and it is a leading cause of long-term disability (2,3). It is estimated that more than 9% of the US population has diabetes, which is the leading cause of kidney failure, lower-limb amputations other than those caused by injury, and new cases of blindness among adults (4). Additionally, more than one-third of US adults have obesity, which is associated with several chronic conditions (5,6).
