BACKGROUND: Due to the increased frequency of smoking in pregnant women, an interest study mechanisms fetoplacental unit women with tobacco addiction has also been all over world. The effect low degrees a woman on fetus not studied available literature.
 AIM: aim this was identify growth and developmental abnormalities at 30-34 weeks gestation third-trimester ultrasound screening.
 MATERIALS AND METHODS: Pregnant who were observed Northern Medical Clinical Center named after N.A. Semashko, Arkhangelsk, Russia examined during screening. A continuous examination three screenings carried out, third screening performed 1048 individuals.
 RESULTS: survey cohort included 120 using inclusion criteria. Two groups formed depending presence or absence pregnancy. first group contained non-smoking (n = 40); second comprised smokers pregnancy 80). Comparison fetal development parameters out two subgroups: subgroup only consisted trimester (embryonic period) b throughout All took part signed Patient Informed Consent form. design observational, cross-sectional (one-step). main manifestations disorders estimated weight, tubular bone length head circumference by gestational age. Low (below 10th percentile) weight age recorded smoke (p 0.001) 90.0% cases even weak degree addiction. It accompanied sizes detected 10.0% among stopped 15.0% those continued This result confirmed early symmetrical intrauterine restriction fetus. had significantly more often 5th fetometric characterizing growth: femur 0.01), shinbone 0.035), shoulder 0.004), biparietal size 0.006), 0.002). values found 50.0% smokers. In signs P10-95 0.027) than non-smokers, for 29.8% cases. addition, fetuses smokers, elevated ratios abdominal found, which indicated restriction. fetometry data obtained anthropometric measurements newborns term delivery, full-term being lower 0.040).
 CONCLUSIONS: Fetuses likely have weights
