    Objectives

    This study examined whether recent changes in smoking prevalence among pregnant women have affected risks of small-for-gestational-age births.

    Methods

    With data for all live single births in Sweden from 1983 through 1992 (n=1 048 139), odds ratio [ORs] and attributable risks of small-for-gestational-age births were calculated for 1983 through 1985,1986 through 1989, and 1990 through 1992.

    Results

    Daily smoking decreased from 29.4% in 1983 to 21.8% in 1992.

    For the three time periods, the odds ratios of small-for-gestational-aged births by maternal smoking were almost identical :

    • 1-9 cigarettes/day OR=2.1 or 2.2 ;

    • for>10 cigarettes/day,

    • OR=2.8. The attributable risk of smoking for small-for-gestational-age births declined from 26.2% in 1983 through 1985 to 20.9% in 1990 through 1992.

    Conclusions

    The findings point to a true decrease in tobacco exposure during pregnancy and a reduction in the attributable risk for small-for-gestational-age births.
