Insecticide affects infancy development HealthCentersOnline Dec 18
(HealthCentersOnline) - Women who are exposed to the insecticide
chlorpyrifos during pregnancy are at increased risk of having babies with
significantly poorer mental and motor development as well as behavioral
problems during early childhood, according to a new study. The study was
conducted by researchers from the Columbia Center for Children's
Environmental Health at Columbia University's Mailman School of Public
Health and the Centers for Disease Control and Prevention (CDC).
Chlorpyrifos is an insecticide used for large-scale crops throughout the
world, although it was banned for household pest control use in the United
States in 2001. Previous research has shown that chlorpyrifos exposure in
utero can affect birth weight and length. This study established a link
between exposure to chlorpyrifos during pregnancy and developmental problems
in the offspring of women who are exposed. This research is part of an
ongoing study examining the effects of exposure of pregnant women and babies
to indoor and outdoor air pollutants, pesticides and allergens.
For this study, the research teams assessed the growth and development of
about 250 infants from New York City who were born between 1998 and 2002. By
their third birthdays, those children with the highest levels of
chlorpyrifos at birth showed significantly lower levels of mental
development and motors skills than children with lower exposure levels to
the insecticide. The children with the most exposure also were more likely
to show early signs of behavior and attention problems.
"These findings indicate that prenatal exposure to the insecticide
chlorpyrifos not only increases the likelihood of developmental delays, but
may have long-term consequences for social adjustment and academic
achievement. Relatively speaking, the insecticide effects reported here are
comparable to what has been seen with exposure to other neurotoxicants such
as lead and tobacco smoke," Dr, Virginia Rauh, lead author and investigator
of the study, said in a recent press release.
The research appears in this month's issue of the journal Pediatrics.
