Smoking habits in early pregnancy.
In a prospective study, 2051 women were interviewed in early pregnancy regarding their own smoking habits as well as smoking habits among closely related persons. Fifty-five percent of the women had at one time or another been daily smokers. Of the 673 women (33%) smoking at the time of conception, 150 had quit smoking at the time of the interview (6 to 10 weeks later). Continued smoking was more common among women, whose parents had been smokers and among those whose husbands were smokers. Continued smoking was also more common among heavy smoking women (greater than 10 cigarettes per day), women who started to smoke at an early age and among women with previous births.
