Birth cohort studies provide a valuable research platform for investigating today's major research questions and evaluating how health and well-being can be improved.

The Rhea study is a ground breaking longitudinal research study of mother-child pairs, designed to identify the effects of mother's diet as well as other environmental and life style factors during pregnancy and after birth on maternal and child health. Eventually, results forthcoming from the Rhea study have to contribute to the development of strategies for optimizing health and healthcare for pregnant women and children.

The primary exposures of interest include environmental chemicals and lifestyle factors while the primary study outcomes include pregnancy outcomes, offspring obesity and cardiovascular risk factors, asthma and atopy, and cognition.
