PIP: The article reviews the relationship between smoking habits of the mother and pregnancy, delivery, and the newborn. Nicotinic acid affects the central nervous system, and produces several cardiovascular, gastrointestinal and respiratory effects on people who inhale the smoke. 2095 pregnant patients were controlled in Caracas, Venezuela, 38.4% were smokers. Although the habit of smoking did not seem to modify fetal movements, it did modify fetal cardiac frequency. Length of gestation was similar for smoking or nonsmoking mothers; incidence of spontaneous abortion was 3 times higher for smoking mothers, who also had a higher incidence of premature rupture of membranes. The incidence of preeclampsia and hemorrhage was lower for smoking mothers, whose deliveries did not significantly differ from those of nonsmoking mothers. Mothers who were smokers had a higher risk of premature deliveries and, consequently, a higher risk of low birth weight babies. This last very important factor did not change in primiparous or multiparous mothers, or with age, or with the family's socioeconomic status, or with smoking habits of the father. It did change, however, with the number of cigarettes smoked every day by the mother. The relationship between sex of the newborn and smoking is not clear; what is clear is that there is a relationship between smoking and fetal or neonatal mortality, which is consistently higher for babies born to smoking mothers. Incidence of congenital malformations was found similar for babies of both groups of mothers, while, apparently, twins were born more often to mothers who smoked. Finally, nicotinic acid did definitely inhibit or reduce lactation.^ieng
