The purpose of the Pregnancy, Environment and Lifestyle Study (PETALS) is to explore how health, the environment and lifestyle factors are related to healthy pregnancy and delivery. Conducted by researchers at the Division of Research at Kaiser Permanente Northern California, the study is comparing women with and without gestational diabetes mellitus (GDM) in relation to various exposures.  Biomonitoring California laboratories are analyzing bisphenol A, benzophenone-3, triclosan and creatinine in urine samples. Investigators will assess how exposures impact health outcomes in both the women and their children. 

PETALS is a nested case-control study, drawn from a birth cohort.  The total cohort includes 3,350 pregnant women, being followed prospectively from pregnancy through the birth of their child. The study will look at 300 women who have GDM compared to 600 matched control women who do not have GDM.

The study is funded by the National Institute of Environmental Health Sciences of National Institutes of Health (R01ES019196).
