Cohort of Young Girls' Nutrition, Environment, and Transitions (CYGNET)

The Cohort of Young Girls' Nutrition, Environment, and Transitions (CYGNET) study is conducted by the Kaiser Permanente Northern California Division of Research, the Environmental Health Investigations Branch of the California Department of Public Health, and Zero Breast Cancer as part of the Breast Cancer and the Environment Research Program (BCERP) sponsored by the National Institutes of Health.  CYGNET identifies chemical exposures in girls in the San Francisco Bay Area and assesses the relationships of these exposures and other lifestyle factors to possible health effects, such as obesity and timing of puberty.  Biomonitoring California laboratories analyzed metals in blood samples from a subset of CYGNET participants.
