10 Years


Celebrating the New Hampshire Birth Cohort Study's 10 Year Anniversary!

Since 2009, the New Hampshire Birth Cohort study has been investigating how the influence of environmental contaminants might affect the health of pregnant women and their children. With the help of our valued study participants we have made great strides in identifying environmental risks that could impact the health of you and your child in the future. We have had the pleasure of enrolling and getting to know all of our study participants over the years and we hope we can provide helpful information to protect you and your child's long-term health and wellbeing. This year we celebrate the 10th anniversary of our study! Your participation in our study has contributed to groundbreaking discoveries in children's environmental health research. This year Gov. Chris Sununu of New Hampshire signed a bill that limits the acceptable amounts of arsenic in the state's public drinking water systems. This decision was greatly influenced by our research which would not have been possible without everyone in the New Hampshire Birth Cohort Study family!
