Effect of Preventive Education on Reducing Urinary Bisphenol-A Levels in Adolescents

March 4, 2024 updated by: Fatma Ulusoy, Akdeniz University

A Comparison of the Effects of a Plastic-Free Nutrition Program, Interactive Education, and Exposure Feedback on Bisphenol-A Levels in Adolescents With Packaged Product High Usage

It is known that Bisphenol-A (BPA) is the endocrine disrupting chemical that is most exposed by oral intake in daily life. Critical life periods when the sensitivity to these substances is known to be maximum; prenatal, postnatal and adolescence periods. The aim of this study is to compare the effects of plastic-free nutrition program, interactive education and BPA exposure feedback on urinary Bisphenol-A levels in adolescents with high use of packaged products.

Detailed Description

By simple random sampling, female adolescents (n=36) staying in a high school hostel will be the intervention group, female adolescents not staying in hostels (n=36) will be the first comparison group, and female adolescents from another high school (n=36) will be the second comparison group. Plastic-free nutrition program (plastic-free diet, peer mentoring, interactive education and BPA exposure feedback) will be applied to the intervention group. Interactive training and BPA exposure feedback will be given to comparison group one, while only BPA exposure feedback will be given to comparison group two. Before and after the interventions, urinary BPA levels, use of plastic packaged products and bad nutrition attitudes of the adolescents will be monitored.
