Summary
This study aimed to investigate factors predicting lapse among pregnant and non-pregnant women when trying to stop smoking. A total of 40 women, pregnant and non-pregnant, were investigated over a 2-week period when trying to stop smoking. One-quarter of the women lapsed every day. Not being pregnant was a significant predictor for the occurrence of any lapse during the time period, whereas age, number of years of smoking, number of earlier attempts to stop smoking, and number of cigarettes smoked per day did not predict lapse. There was a four times higher risk for lapse in non-pregnant compared with pregnant women. Being pregnant gives an opportunity to help stop smoking with a considerably lower risk of lapse compared with non-pregnant women.
