Grantee Explores Right-to-Know in Community-Based Participatory Research
By Negin Martin
On Dec. 1, NIEHS welcomed grantee Julia Brody, Ph.D. as the latest speaker in the Keystone Science Lecture Series sponsored by the NIEHS Division of Extramural Research and Training (DERT). Brody discussed the policy and ethical considerations involved in deciding how and when to report test results to individuals and communities participating in personal exposure assessment studies and what information should be included.
According to Brody(http://www.silentspring.org/staff/julia-brody-phd) , sharing results with communities can help people learn about sources of exposure, so they can take action — both in their own lives and through the democratic process. Positive outcomes of informing participants about exposure data include raising environmental literacy, expanding subjects' right-to-know, and building trust.
At the same time, researchers must consider the possibility that data could lead to emotional stress, unnecessary or counterproductive interventions, and stigma.
Providing participants' results builds awareness, trust, and pride
"In traditional clinical ethics, experts decide what to report to study participants, often limiting information to findings that are medically relevant to the individual," Brody said. "In our studies of emerging contaminants, we don't know yet what the health implications will be, but we respect our participants' right to learn their results, consistent with the human research ethics criteria of autonomy, beneficence, and justice."
As Brody explored this ethical dilemma, she reviewed the approach and findings her team of investigators published in an American Journal of Public Health study(http://www.ncbi.nlm.nih.gov/pubmed/17666695?itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_RVDocSum&ordinalpos=5) in 2007, a Journal of Health and Social Behavior study(http://www.ncbi.nlm.nih.gov/pubmed/19181047?itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_RVDocSum&ordinalpos=3) in 2008, and a review(http://www.ncbi.nlm.nih.gov/pubmed/19250551?itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_RVDocSum&ordinalpos=1) in Environmental Health earlier this year. She proposed strategies for reporting exposure results to maximize benefit and minimize negative outcomes for participants.
Presentation of the report also plays an important role in establishing trust and improving environmental knowledge in a community, Brody explained. Researchers should present their results clearly, take the time to describe what is known, and clearly outline the limitations of the study.
Brody shared her own experiences reporting exposure data to individuals as part of her NIEHS-funded research. In her studies, she found that people wanted to know about their individual results. Volunteers expressed pride in participating in a study that helped their communities, and they were generally surprised by the findings, which showed that indoor pollution builds up from everyday consumer products.
Research advances outpace ethical guidelines
Brody explained that recent studies have discovered increasing levels of potentially harmful pollutants in people and raised public awareness of related health risks. Referring to several examples of the "flood of personal exposure information," Brody noted that the ability to detect chemicals in tissue samples and the environment has advanced faster than the development of ethical guidelines and methods for interpreting and communicating results.
Brody is the executive director of the Silent Spring Institute(http://www.silentspring.org/about-us) . Established in 1994, Silent Spring is a collaborative effort between scientists and activists to identify environmental factors that influence women's health and contribute to breast cancer.
