Most US children attend school for at least 6 hours a day and consume as much as half of their daily calories at school. CDC Healthy Schools in the Division of Population Health recommends that schools create an environment that helps students make healthy choices about foods and beverages. Some examples of CDC-recommended actions to improve nutrition in schools are:
- Promote access to and participation in school breakfast and lunch.
- Ensure that all foods and beverages sold or served outside of school meal programs are nutritious and appealing.
- Offer healthy foods and beverages at school celebrations and events and only nonfood items as rewards.
- Provide more access to drinking water.
- Promote healthy foods and beverages—for example, by pricing them lower than less healthy items.
- Include nutrition education in health education, throughout the school day, and in after-school programs—for example, through school gardens and farm-to-school activities.
CDC funds state departments of education to increase the number of students who consume nutritious foods and beverages.
Improving Physical Education and Physical Activity Opportunities in School
About one-quarter of adolescents get the recommended 60 minutes a day of physical activity. CDC Healthy Schools recommends that schools use all available opportunities for students to get physical activity and learn how to be physically active for a lifetime. Schools are encouraged to:
- Offer physical education to increase students’ knowledge, skills, and confidence to be physically active and improve their health and academic outcomes, such as increased physical activity, improved grades and standardized test scores, and better classroom behavior.
- Offer recess at all grade levels to encourage students to be physically active and engaged with their peers in activities of their choice.
- Integrate physical activity into classroom instruction.
- Promote before- and after-school opportunities to be physically active, through walking or biking programs, physical activity clubs, intramural programs, and competitive sports.
CDC funds state departments of education to increase the number of students who participate in daily physical education and physical activity.
Preventing Youth Use of Tobacco Products
Nearly 9 in 10 adult cigarette smokers in the United States first tried a cigarette before age 18. Every day, about 2,000 young people under 18 try their first cigarette, and more than 300 become daily cigarette smokers. About 7 of every 100 middle school students and about 27 of every 100 high school students report current use of some type of tobacco product.
Any tobacco use among young people—whether burned, electronic, or smokeless—is unsafe because nicotine is addictive and can harm the developing brain. Nicotine exposure during adolescence affects learning, memory, and attention and primes the brain for addiction.
CDC’s Office on Smoking and Health is at the forefront of the nation’s efforts to reduce deaths and prevent chronic diseases that result from tobacco use. CDC’s activities include:
- Monitoring youth tobacco use through the National Youth Tobacco Survey, which focuses on use, beliefs, and knowledge about tobacco among middle and high school students.
- Funding youth tobacco prevention initiatives through the National Tobacco Control Program, which supports all 50 states, the District of Columbia, 8 US territories, and 12 tribal organizations for comprehensive tobacco control efforts and quitlines.
- Helping parents, educators, health care providers, and other youth influencers understand and talk to young people about the risks of tobacco products by developing easy-to-understand materials that make sense of the best available science.
Helping Children and Adolescents Manage Chronic Conditions
As many as 1 in 4 US students has a chronic health condition such as asthma, diabetes, or epilepsy. Managing students’ chronic health conditions can be a challenge for school personnel. A coordinated effort that involves family members, community groups, social service agencies, and medical providers working with teachers, school nurses, and staff is crucial.
The health care needs of children with chronic health conditions can be complex and continuous and include both daily management and potential emergencies. Ensuring that students have the health services they need to manage their chronic conditions while at school is important in helping them stay healthy and ready to learn.
CDC funds state education agencies to improve the delivery of health services in schools and increase the number of students who can effectively manage their chronic health conditions.
Promoting the Use of Dental Sealants
Dental sealants are protective coatings applied to the chewing surfaces of the back teeth, where most cavities start. Although use of sealants has increased, this effective intervention remains underused. Less than half of children aged 6 to 11 have dental sealants. The use of dental sealants varies among racial and ethnic groups, as does the prevalence of treated and untreated cavities. In addition, children from lower-income families are twice as likely to have untreated cavities as those from higher-income families, but they are less likely to have dental sealants.
School sealant programs provide dental sealants at no charge to children who are less likely to receive private dental care. These programs provide sealants to students during the school day using mobile dental equipment. Providing these services at school is especially effective at reaching children at risk of developing cavities.
Programs funded by CDC’s Division of Oral Health focus on schools that serve children at high risk of cavities. CDC provides guidance to state and community programs to help them plan, set up, and evaluate school sealant programs and to complement services provided by private dentists. An online data collection tool called SEALS allows programs to evaluate the cost-effectiveness of their efforts.
Promoting Better Sleep
Sleep is increasingly recognized as a component of good health. Getting enough sleep can help children prevent obesity, type 2 diabetes, attention and behavior problems, poor mental health, and injuries. Children aged 6 to 12 need 9 to 12 hours of sleep a night. Teens aged 13 to 18 need 8 to 10 hours of sleep a night.
CDC works to increase parents’ awareness about their children’s need for good sleep and how they can help their children get enough—for example, by setting the same bed and wake-up times each day, including on the weekends, and by modeling good sleep behaviors.
