Abstract

Among residents living close to agricultural fields who are potentially exposed to pesticides, pregnant women and their fetuses are of particular concern for their vulnerability to environmental chemicals. In this collaborative multicenter study, we covered a wide distribution of participants in the most important fruit production zone of north Patagonia (Argentina) to investigate whether maternal residential proximity to fruit croplands with intense pesticide applications (rural group –RG-) is associated with pregnancy complications and alterations in their newborn parameters compared to the urban population (urban group –UG-). A total of 776 pregnant women met the inclusion criteria. The percentage of threatened miscarriage was significantly higher in the RG than in the UG. The percentage of miscarriage, threat of premature labor, intrauterine fetal death, preterm premature rupture of membranes, and intrauterine growth retardation were similar in both groups. Newborn anthropometric parameters were corrected by sex and gestational age prior to statistical analysis. Length at birth and head circumference were lower in the RG than in the UG. Birth weight was similar in both groups. The percentage of head circumference less than the 5th percentile and the ponderal index were greater in the RG than in the UG. Our results suggest that proximity to pesticide applications may increase the risk of pregnancy complications and altered newborn parameters.

Highlights

• Higher threatened miscarriage was the pregnancy complication associated to residential proximity to Patagonian fruit croplands with pesticide applications.

• Lower length at birth was associated to residential proximity to the fruit croplands in High Valley of Negro River, in Argentine Patagonia.

• Women living within a short distance of this agricultural field had babies with lower head circumference at birth.

• Higher ponderal index in newborns was associated to residential proximity to this fruit-growing zone.
