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

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.

About this study

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.

Primary outcomes

  1. Urinary BPA level

    Time frame: Baseline-Second month

    Urinary Bisphenol A

Secondary outcomes

  1. Plastic Packaged Product Usage

    Time frame: Baseline-Second month

    0-20 points indicate the use of low plastic packaged products, 21-40 points indicate the use of medium plastic packaged products, 41-60 points indicate the use of medium-high plastic packaged products, and 61-80 points indicate the use of high plastic packaged products.
