Jane Schmitz, clinical assistant professor and research and curriculum advisor for the USC Institute for Global Health, is the lead author of an article published by the British Medical Journal (BMJ) on Jan. 10, 2012, documenting a previously unknown benefit of vitamin A supplementation among preschool children on risk of hearing loss in young adulthood.
About the study:
