^*.Smoking mothers only (n=331)

A Stepwise backward logistic regression model was applied. Variables entered on step 1: child’s gender, child’s age, number of children, father’s educational status, mother’s educational status, father’s number of cigarettes per day, spouse smoker, friends or relatives allowed to smoke in the house, belief that they do not want their child to become a smoker.
