* low birth weight *
********************************
* These data come from Appendix 1 of Hosmer and Lemeshow (1989), and were
collected at Baystate Medical Center, Springfield MA, during 1986.
* Low birth weight is an outcome that has been of concern to physicians
for years. This is due to the fact that infant mortality rates and birth
defect rates are very high for low birth weight babies. A woman's behavior
during pregnancy (including diet, smoking habits, and receiving prenatal care)
can greatly alter the chances of carrying the baby to term and, consequently,
of delivering a baby of normal birth weight.
