Impact of Parental Training in Endocrine Disruptors on the Excretion of Urinary Biomarkers in Newborns

This study is looking at how training new parents can help reduce their newborns' exposure to certain everyday chemicals called endocrine disruptors (EDs). These chemicals can affect hormones and are found all around us. Some EDs leave the body quickly through urine. The study wants to see if teaching parents simple steps can lead to lower levels of these EDs in their babies' urine. The first 1,000 days of a baby's life (from pregnancy through infancy) are an important time when they are more vulnerable to these chemicals. By providing information during this period, the researchers hope to reduce exposure and understand the impact of these changes. This research will help us learn more about how everyday chemicals affect babies and how we can best protect them.

Endocrine Disruptors in Newborns and Infants

What is this study about?

This study is about understanding and reducing the impact of certain everyday chemicals, called endocrine disruptors (EDs), on newborn babies. You might have heard about these chemicals before – they are found in many things around us, like some plastics, cleaning products, and even certain foods. The concern is that EDs can get into our bodies and affect our hormones, which are important chemical messengers that control many body functions.

We know that avoiding all EDs is impossible, but scientists believe that reducing exposure through simple actions can be helpful. Some EDs leave the body quickly through urine, and these are the ones this study will focus on. This means that if we make changes to reduce exposure, we should be able to see the results fairly quickly. The study hopes to provide useful information for parents about how to protect their babies from these chemicals.

The main idea behind this research is to see if giving new parents some practical training on simple steps they can take will lead to lower levels of these specific EDs in their babies' urine. The study will also gather information about how much babies are exposed to these chemicals before they start eating different foods. This research is important because it will help us understand more about how our environment affects babies and how we can better support their health from the very beginning.

Key takeaways

Everyday chemicals can affect babies' health by interfering with hormones.
This study teaches parents simple ways to reduce their baby's exposure.
Researchers will check urine samples to see if the training makes a difference.
Focuses on chemicals that leave the body quickly.
Aims to understand how our environment impacts newborn babies.

Who may be eligible?

To be part of this study, newborn babies need to have been born at Bron hospital after 37 weeks of pregnancy and be a healthy weight. Their parents must also be signed up to a social security scheme or something similar and give their written permission for their baby to take part.

However, babies cannot join the study if they were born with a health problem that was found during pregnancy or after birth. Also, if the parents don't speak French, their baby won't be able to participate in this particular study.

Could this study suit you?

Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.

Was your baby born at Bron hospital?
Was your baby born after 37 weeks of pregnancy (not prematurely)?
Is your baby a healthy weight?
Are you, the parents, able to read and speak French?
Are you covered by social security or a similar health scheme?

Answer every question to see your result.

What does participation involve?

The study involves new parents receiving some training on how to reduce their baby's exposure to certain chemicals. You would also be asked to fill out some questionnaires. For your baby, a urine sample would be collected to measure the levels of these chemicals. The total duration of your baby's participation in the study would be very short, typically within the first few days after birth.

Potential risks and benefits

Participating in this study might offer the benefit of learning practical ways to reduce your baby's exposure to everyday chemicals. It will also help researchers learn more about how to protect newborns. The main procedure for your baby is providing a urine sample, which is a common and generally safe process. You are free to withdraw your consent and your baby from the study at any time without giving a reason, and this will not affect your baby's medical care.

Common questions

What are 'endocrine disruptors'?

They are chemicals found in everyday products that can affect healthy body functions, especially hormones.

Why focus on newborns?

Newborns are more vulnerable to these chemicals, and understanding exposure early can help improve their health.

What does the parental training involve?

It's about learning simple, practical steps to reduce your baby's exposure to certain everyday chemicals.

How will you check the results?

Researchers will check for levels of these chemicals in your baby's urine before and after the training.

Is this study safe for my baby?

The main task for your baby is providing a urine sample, which is a safe, routine procedure.
