The percentage of babies being born either premature or underweight has risen, according to a study based on data from the U.S. National Centre for Health Statistics. For instance, the proportion of low birth-weight babies increased from 7 percent to 8 percent.
The analysis was undertaken by the organisations Child Trends and Kids Count. Among the reasons experts cite for these trends are the increasing incidence of twin and triplet pregnancies due to women using fertility drugs, and the increasing use of drugs to induce labour.
Among the other developments noted in the study:
Births to unwed mothers increased from 28 percent to 33 percent – but most of the increase occurred in the period 1990 to 1994. Births to teen mothers stayed at 13 percent over the 1990-98 period.
