Comparison of the Effects of Plastic-Free Diet, Plastic-Free Diet Education and Exposure Feedback on Urinary Bisphenol: A Levels in Adolescents

This study compared the effects of a plastic-free diet program, a plastic-free diet education program, and BPA exposure feedback on Bisphenol A levels in adolescents with high use of packaged products. As a result of the questionnaires, adolescents with "high" usage of plastic-packaged products and "low" attitudes toward healthy eating were assigned to intervention groups simple random sampling method (<i>n</i> = 108) and urinary samples were collected. Post-tests were conducted after the plastic-free diet was applied to intervention 1, the plastic-free diet education program and BPA exposure feedback to both Intervention 1 and Intervention 2, and BPA exposure feedback to Intervention 3. All interventions were effective in reducing urinary BPA levels, decreasing the use of plastic-packaged products, and improving attitudes toward healthy eating. Implementation implications: (a) training for school nurses and stakeholders, (b) education for adolescents and families, (c) collaboration with stakeholders, and (d) enhancing guidance and counseling in school health services.
