Exposure to sun could affect babies' bones

April 17, 2009 A study in the Journal of Clinical Endocrinology and Metabolism finds women who get some sun during the last trimester have children with stronger bones.

Researchers found, among 10-year-olds they assessed, those whose mothers were in their last trimester during sunny months tended to have larger bones.

The connection is presumably explained by Vitamin D.

It's synthesized in the skin after sun exposure and plays a key role in bone health.

Scientist's say they are by no means recommending women bask in the sun. But they say it's possible that a mother's Vitamin D levels late in pregnancy have lasting effects on their children's later bone development.
