The objective of the study was the evaluation of effect of passive smoking among pregnant women on the health condition of their newborn babies. The study covered 150 healthy, non-smoking women from the Lublin Region. Among the total number of respondents, 45.34 % were not exposed during pregnancy to passive smoking at their workplace, while 13.33 % were passive smokers throughout the whole period of pregnancy. The state of their babies was assessed according to the APGAR Scale. A statistically significant correlation was noted between the maternal exposure to passive smoking during pregnancy and evaluation of the babies according to the APGAR Scale. No statistically significant relationship was noted between the date of delivery, the birth weight of babies, the onset of lactation, the problems with breastfeeding and maternal passive smoking during pregnancy.
