Material and Methods: Consecutive 576 non-smoking women delivering a singleton live baby were studied. A
pre-designed structured questionnaire was used to record the details of exposure to ETS at home. The maternal
and foetal variables were compared among those who were exposed to ETS vis-à-vis not exposed. Unpaired
Student t-test was used for the comparison of continuous variables and Fisher’s Exact test was used for
categorical variables. Multiple logistic regression analysis was performed after including all variables found to
have significant differences on univariate analysis.
