Research Summary

The Biomarker-based Epidemiology Group is focused on health effects of early exposure to background levels of environmental contaminants. The term "background level" means exposure that occurs in the general population, usually at low levels, with no unusual or occupational exposure. To detect effects of low-level exposure, if any, the group looks at exposure that occurs prior to birth, when susceptibility may be greatest. Future research plans, however, will extend the scope to include childhood exposures. To date, the specific outcomes addressed in this research have ranged from reproductive outcomes to children’s performance on neurobehavioral tests. Matthew P. Longnecker, M.D., Sc.D., is the head of the Biomarker-based Epidemiology Group.

When Longnecker began work in the field, he studied persistent organic pollutants exclusively. Persistent organic pollutants are major public health concerns because they are omnipresent in the ecosystem and may cause adverse health effects at background levels of exposure via diet. Examples are DDE, the major metabolite of the insecticide DDT, polychlorinated biphenyls (PCBs), and dioxin, also known as tetrachlorodibenzo-p-dioxin or TCDD. Epidemiologic research on potentially adverse health effects of the insecticide DDT continues to impact public health policy, and Longnecker has ongoing studies that address the topic.

Perfluorinated alkyl substances, another type of persistent organic pollutant, have recently been recognized as a potential threat to the health of the general population.  Longnecker has completed and has ongoing a series of studies on these substances in relation to reproductive and pediatric outcomes.  In addition, he has begun studying the effects of early, low-level exposure to the nonpersistent pollutants, bisphenol A and organophosphate pesticides.

Longnecker received a B.S. from Antioch College, an M.D. from Dartmouth Medical School and a Sc.D. from Harvard School of Public Health. He is board-certified in internal medicine. He was an assistant professor of Epidemiology in the School of Public Health at the University of California, Los Angeles before coming to NIEHS in 1995.  Longnecker is a senior investigator in the U.S. Public Health Service at NIEHS.  He also serves as an adjunct professor in the Department of Epidemiology, School of Public Health, University of North Carolina at Chapel Hill.

Studies

DDE and PCBs in the Collaborative Perinatal Project

This study explores the health effects of in utero exposure to organochlorines such as DDE and polychlorinated biphenyls (PCBs) using biologic specimens from the Collaborative Perinatal Project (CPP).


Generation R

Generation R is a prospective study of 8,000 children—born in 2002-2006 in Rotterdam, The Netherlands—who are being be followed from early fetal life to young adulthood.  The study is spearheaded by scientists at the Erasmus Medical Center.  NIEHS supported collection of urine specimens taken at three times during pregnancy from approximately 2,000 subjects in 2004-2006.  These will be used to examine exposure to selected environmental contaminants and offspring health.


Norwegian Mother & Child Cohort Study (MoBa)

The Norwegian Mother & Child study (MoBa) is an ongoing long–term prospective cohort study of 100,000 pregnant women and their babies. In collaboration with the Norwegian National Public Health Institute, NIEHS supported the collection of additional biologic specimens from the pregnant women.
