Results Communication in Breast Milk Biomonitoring Studies: A Scoping Review and Stakeholder Consultation

Abstract

Researchers investigating breast milk contamination face substantive ethical dilemmas regarding how biomonitoring results should be conveyed, with limited guidance available to help them. To identify effective processes for undertaking such research, we sought to critically assess practices being followed in reporting results. To consider how researchers have reported on this and related ethical issues, we searched three English-language databases for articles published between 2010-2016 on measuring presence of pesticides in breast milk. Data on report-back processes and discussed ethical issues were charted from retained articles (n=102). To deepen our understanding of issues, we further consulted authors (n=20) of retained articles through an online survey. Quantitative data from surveys were tabulated and qualitative data were analyzed thematically. Of 102 articles, only two mentioned sharing results with subjects, while 10 out of 20 survey participants confirmed that they had indeed conducted report-back in their studies. Articles discussing ethical considerations were few (n=5), although researchers demonstrated awareness of common ethical debates to inform report-back decisions. Our review suggests that greater explicit attention should be given to practices of engaging study subjects and their communities in contamination studies so that an evidence base on best ethical practices can be more readily available.
