Officials from the U. S. government's 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.
The study will examine hereditary and environmental factors such as exposure to certain chemicals that affect health.
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.
Officials said more than $ 200 million has been spent already and the study is projected to cost $ 3.2 billion.
"We anticipate that in the long term, what we learn from the study will result in a significant savings in the nation's health care costs," Dr. Duane Alexander, who heads the NIH 's Eunice Kennedy Shriver National Institute of Child Health and Human Development, told reporters.
The study will begin in January when the University of North Carolina and the Mount Sinai School of Medicine in New York start signing up pregnant women whose babies will then be followed to age 21.
Some of the early findings will be about factors behind pre-term birth, which has become more common in recent years, according to Dr. Peter Scheidt of the NIH, who heads the study.
The people taking part will be from rural, urban and suburban areas, from all in- come and educational levels and from all racial groups, the NIH said.
The aim of the study is to find new ways to______.

A. conduct research
B. track public health
C. prevent or treat illness
D. speed up development

While a speech therapist is not trained to help persons with severe emotional disorders, the therapist does receive extensive training in such areas as anatomy(as it relates to speech, concentrating on the diaphragm, tongue, and palate), physics(particularly relating to sound), and language and communications. Some therapists take classes in elementary psychology as well.
The speech therapist must be able to diagnose the type and severity of the speech defect, then prescribe a series of treatments. While some people with severe handicaps receive individual instruction, most patients are comfortable receiving group therapy with others who have the same problem. If a patient is found to have a physical handicap that is impeding his progress, he is sent to a doctor with whom the therapist works closely.
Many therapists have a high success rate with their patients. No scientific studies have yet shown whether the intervention of the therapist was in fact the sole cause of the improvement of the patients, or whether time and maturity helped as well. A recent study has shown that persons who have not received speech therapy have often been "cured' of their problems merely by being around others without the problem. However, that same study showed that those few persons who were not treated by therapists had extremely low self-esteem and considered themselves " different" and "retarded". The therapists often are able to make the patients see that while they are different, the difference is not of their own making, that they have not done something wrong. Therapists try to reach children when they are very young, before they have had an opportunity to be teased by other children or made to feel they are "stupid". Therapists often work with whole families, encouraging the parents and siblings to listen to the patients, taking the time to help them feel they are an important part of the family, not just brushing them off because the effort of interpreting their speech is too great or time-consuming.
Which of the following is not listed as a function of the speech therapist?

A. To diagnose the nature and severity of the defect.
B. To determine the cause of aphasia in children who are physically capable of speech.
C. To give emotional support to a child, showing her that the defect is not fault of her own.
D. To prescribe medication that will help the patient relax and use her speech muscles properly.
