Levels of Contaminants in Human Milk (Conta-Lait)

This study has been completed.
Information provided by (Responsible Party):
Assistance Publique - Hôpitaux de Paris Identifier:
First received: April 18, 2013
Last updated: October 8, 2015
Last verified: October 2015
Recent international data have shown that the levels of chemical substances found in human milk could be at risk for breastfed infants. New data are necessary to assess this risk among French newborns.

Condition Intervention
Lactating Women Who Give Their Milk to One of the 6 Milk Banks Participating in the Study Other: Breastmilk

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Evaluation of Different Chemical Substances in the Milk of Breastfed Infant

Further study details as provided by Assistance Publique - Hôpitaux de Paris:

Primary Outcome Measures:
  • Presence of contaminants (PCB, dioxins, furans and brominated flame retardants) [ Time Frame: at the moment of the milk's donation ]
    analysis of contaminants

Secondary Outcome Measures:
  • evaluate the concentration of other contaminants, perfluorinated compounds, organochlorine pesticides and inorganic compounds [ Time Frame: at the moment of the milk's donation ]
    analysis of contaminants

  • To estimate the exposure of breastfed infants and to assess the risk in this population [ Time Frame: at the moment of the milk's donation ]
    statistical analysis

Biospecimen Retention:   Samples Without DNA
4*200 ml of breastmilk homogenizated and frozen -18° Celsius in the milk bank

Enrollment: 187
Study Start Date: October 2013
Study Completion Date: May 2015
Primary Completion Date: May 2015 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Lactating women who give her breastmilk to a milkbank
180 women will be included in 6 milk banks in France during 18 months
Other: Breastmilk
to measure levels of contaminants in human breastmilk samples

Detailed Description:

The objective of this study is to assess levels of certain contaminants in breastmilk. Measurements will be made on breastmilk samples collected in Milk Bank but not suitable for infants due to bacteriological reasons. 6 Milk Banks well distributed on the French territory will be contacted to participate. 180 women will be included. Women who gave their milk and correspond to the inclusion criteria (in particular breastfeeding a child under 6 months at the time of the donation) will be contacted by the investigator by phone. They will be asked to fill in a written consent as well as a questionnaire on socio-demographic data, pregnancy related information and potential environmental exposures.

2 breastmilk samples of 50 mL will be sendsending to the lab for analysis and 2 samples of 50 mL will be collected.
