Detectable Serum Cotinine Levels in self-reported non-tobacco smoke pregnant women

Abstract

Aim: To determine serum cotinine levels in pregnant women who are non-smokers and not exposed to second hand tobacco smoke. Methodology: It was a descriptive study conducted on pregnant women presenting in obstetric department and gave no history of exposure to second hand tobacco smoke. 28 women were included. Serum cotinine was measured to see the exposure status of the women. Results: Out of 28 women, 14 (50%) women had serum cotinine levels above 0.05ng/ml. There was no difference in the mean years of education of the women or their husbands. Conclusion: Only history alone cannot be used to identify the population who is at risk of harmful effects of tobacco smoke via SHS.Biochemical measurements should be done before labelling a person as non-exposed. Education had no role in reporting of second hand tobacco smoke exposure
