　　U.S. to Start $3.2 Billion Child Health Study in January

　　Officials from the U.S. governments National Institutes of Health said they hope the study, to be conducted at 105 locations throughout the United States, can help identify early-life influences that affect later development, with the goal of learning new ways to treat or prevent illness.

　　Researchers will collect genetic and biological samples from people in the study as well as samples from the homes of the women and their babies including air, water, dust and materials used to construct their residences, the NIH said.

　　We anticipate that in the long term, what we learn from the study will result in a significant savings in the nations health care costs, Dr. Duane Alexander, who heads the NIHs Eunice Kennedy Shriver National Institute of Child Health and Human Development, told reporters.
