Childhood obesity is an ongoing epidemic that remains a persistent and escalating crisis in the United States. A new study published in the journal Nutrients has revealed that teachers can play a critical role as potent allies in addressing this pressing concern.
Data from the Centers for Disease Control and Prevention revealed that nearly 14.7 million children and adolescents aged 2 to 19 were affected by obesity from 2017-2020, with a prevalence rate of 19.7%. To tackle this issue, health agencies at the local, state and federal levels have been directing their efforts toward schools as the central hub for potential solutions.
The inclusion of teachers in identifying and incorporating solutions into program delivery can be a significant asset in combating childhood obesity. However, the demanding nature of classrooms and schools for professionals poses a significant hurdle to this endeavor. The onset of the COVID-19 pandemic also further highlighted the urgent need to address the health and well-being of teachers.
The well-being of teachers can directly affect and benefit students. An extensive report by the RAND Corporation in 2022 suggested that a solid student-teacher relationship helps increase engagement and attendance, improve student well-being, decrease behavior concerns and lead to positive outcomes.
Here’s What the Research Showed
The study conducted by researchers at the American University, Washington, evaluated the role of teachers in addressing childhood obesity. This five-year intervention project began in 2017 with the aim of engaging educators in imparting nutrition literacy skills to prevent obesity among elementary school students in Washington, D.C.
Teachers from two comparison and two intervention schools provided demographic data and completed the Teacher Health Surveys before and after the intervention. The primary objective of this study was to assess the effects of a professional development program in providing teachers with the knowledge and skills to integrate nutrition into their lessons.
Overall, 92 teachers from the intervention and comparison schools completed the Teacher Health Surveys at baseline and after the intervention. They were, on average, aged around 36 years old, with 84.8% identifying as female and 68.5% identifying as black. The average aggregate health scores at baseline remained consistent across the age range, gender, teaching duration and grade levels.
A total of 55 teachers from intervention schools attended the professional development program and implemented 71 nutrition lessons in the classrooms successfully. Poisson regression analysis showed that job stress, professional development program attendance and self-efficacy significantly predicted the integration of nutrition lessons into the classroom curriculums.
The sessions began with a well-being component, such as physical activity, mindfulness practices or discussions about eating healthy, and subsequently, a sample lesson from “Serving up MyPlate: A Yummy Curriculum” was also presented. Teachers in the intervention schools had to implement at least three nutrition lessons throughout the year. The Student Nutrition Literacy Survey was administered at the beginning and end of the intervention to assess student knowledge about nutrition, intent and beliefs.
The study showed that when teachers experienced an increase in self-efficacy scores, they were 25% more likely to include nutrition lessons in their classrooms. Additionally, attending extra sessions increased the likelihood by 48%. Interestingly, there was an opposite relationship between self-efficacy and stress. Teachers dealing with high stress tended to have lower self-efficacy scores. The researchers also found a link between health scores, the implementation of nutrition lessons and overall health scores.
Moreover, the baseline knowledge scores showed no significant difference between students in comparison and intervention schools. However, the scores significantly increased among intervention school students who received nutrition lessons from participating teachers. Students receiving three or more nutrition lessons had approximately 10% higher scores than those receiving two or fewer lessons.
The findings of the study showed that a short-term professional development program aimed at supporting the health of teachers and implementing nutrition education was feasible and had the potential for long-term success. However, the improvements in knowledge about healthful eating may not necessarily reflect changes in behavior. Therefore, the foundation for improving student health should start with solutions aimed at supporting the well-being of teachers, and by emphasizing workplace professional development.
The study concluded that empowering teachers with the right knowledge, resources and skills to manage their health helps them act as both the medium and the message in the classroom and as agents of change. Including teachers as collaborators in preventing childhood obesity will not only help put health initiatives into action but also offer the potential for long-lasting positive outcomes.
In summary, this study underscored the feasibility of professional development programs as a means to boost teacher well-being and a potential strategy to prevent childhood obesity.
