The presence of cotinine in their milk was observed in 48 of mothers (32%). Cotinine in the urine was detected in 56 of children (37.3%). There is statistical correlation between the active smoking of women and the presence of cotinine in their breast milk and between a mother's tobacco smoking and the presence of cotinine in her children's urine. It was shown that the mean concentration of cotinine in the milk and urine increased in proportion to the number of cigarettes smoked and this difference was deemed statistically significant. The mean cotinine concentration in the urine of children were the lowest if the only smoker in the household was the father, higher if the only smoker was the mother and the highest in the group of children where two or more persons in the household were smokers. The mean cotinine concentrations in the milk were the highest in groups where only mothers smoke. On the basis of the studies performed, it is possible to conclude that the degree of tobacco smoke exposure among breast feeding infants is proportional to the number of cigarettes smoked by their mother.
