Population study demonstrates cigarette smoking during pregnancy reduces birth weight and increases perinatal mortality, highlighting the benefits of early cessation.

Key Points

To determine the effects of maternal cigarette smoking during pregnancy on birth weight and perinatal mortality, while adjusting for potential confounding variables.
Analyzed pregnancy outcomes in a British population, controlling for mediating maternal and social factors.
Evaluated perinatal risk among mothers who modified their smoking habits by the fourth month of gestation.
Cigarette smoking during pregnancy increased late fetal plus neonatal mortality by 28%.
Maternal smoking reduced infant birth weight by an average of 170 g, independent of maternal and social variables.
Mothers who changed their smoking behavior by the end of the fourth month of pregnancy shifted into the risk profile corresponding to their altered habit.
