Effect of birth year on birth weight and obesity in adulthood: comparison between subjects born prior to and during the great depression in Iceland.

<h4>Background</h4>Many epidemiological studies have linked small size at birth to adverse adult health outcomes but the relative influence of environmental exposures is less well established.<h4>Methods</h4>The authors investigated the impact of prenatal environmental exposu...
