Prenatal and childhood pesticide exposure has been associated with neurodevelopmental disabilities in a number of studies in low-income countries and more recently in the U.S. Only a few studies have been conducted in children with chronic low-level exposure as may be typical for New Zealand. Given New Zealand’s large agricultural industry and extensive mixed agricultural land use pattern, pesticide exposure is likely to be widespread.
We are conducting the first study on pesticide exposure and neurodevelopmental effects in New Zealand. We are conducting a questionnaire survey of 300 farmers’ children, 300 rural non-farmers’ children and 300 urban children. In randomly selected subgroups (150 in each group of children) we will conduct detailed exposure measurements and objective neuropsychological testing. This study will assess the extent of neurodevelopmental health effects related to pesticide exposure in New Zealand children, and will enable the development of preventive interventions.
whether these associations are detectable in all subgroups of children (farm, rural non-farm, and urban).
The overall aim of the study is to contribute to the development of improved control options to reduce pesticide exposures and neurotoxic effects in children.
