The Center for the Health Assessment of Mothers and Children of Salinas (CHAMACOS) Study is the longest running longitudinal birth cohort study of pesticides and other environmental exposures among children in a farmworker community. CHAMACOS means “little children” in Mexican Spanish, which reflects the population we serve.

 

Starting in 1999, we enrolled pregnant women living in California's Salinas Valley, one of the most productive agricultural regions in the nation. We have followed these families for 17 years, measuring exposures to pesticides and other chemicals and assessing children’s growth, health, and development every 1-2 years. In 2010-2011, we expanded the study by enrolling additional 9-year-old children into the cohort. More than 600 children continue to participate in the study and will be followed until adulthood. The CHAMACOS Study has resulted in almost 150 publications shedding light on environmental chemical exposures and health.
