Multicenter Study Comparative StudyReduction of tobacco smoke exposure for pregnant passive smokers using feedback of urinary cotinine test results.
Our objective was to evaluate the level of pregnant women's exposure to tobacco smoke by urinary cotinine testing at prenatal examinations, and to examine the effects of disclosing the results of urinary cotinine tests to pregnant women and their families on their smoking activities. ⋯ The feedback of the urinary cotinine test results at prenatal examinations decreased the level of exposure of pregnant passive smokers and non-smokers to tobacco smoke.
