The Influence of Smoking on Breast feeding Among Women Who Quit Smoking During Pregnancy.

INTRODUCTION

Understanding factors related to breast-feeding intention, initiation, duration, and weaning among women who quit smoking as a result of pregnancy may inform interventions to increase breast-feeding rates among women who smoke.

METHODS

Women (N = 300) who quit smoking as a result of pregnancy and enrolled in a postpartum relapse prevention trial were interviewed about breast-feeding intention prior to delivery. Breast-feeding initiation, duration, reasons for weaning, and relapse to smoking were assessed at 12-weeks postpartum.

RESULTS

The majority of pregnant former smokers intended to breastfeed (68%), and actual rates of breast feeding were higher (74%). Among women who initiated breast feeding, weaning before 2 months was common (41%). For most women (69%), smoking had no effect on breast-feeding decisions. Among the 31% of women who reported that smoking influenced their feeding decisions, 83% indicated that they did not smoke or decreased smoking frequency in order to breastfeed while 17% did not breastfeed or quit breast feeding in order to smoke. Women who decided to forgo breast feeding to smoke were significantly more likely to have a high school education or less (p < .001) and to be African American (p < .0001) than those who had other reasons not to breastfeed.

CONCLUSIONS

Most women who quit smoking during pregnancy initiate breast feeding, and the majority report smoking did not influence feeding decisions. Importantly, among women for whom smoking did influence feeding decisions, most reported changing smoking behavior to enable breast feeding. Interventions to increase breast-feeding initiation and duration may decrease postpartum relapse and improve maternal and infant health.

IMPLICATIONS

This study extends the literature on women's perception of the influence of smoking on breast feeding by assessing breast-feeding intent, initiation, duration, and reasons for weaning longitudinally among women who quit smoking as a result of pregnancy. The results support a need for additional research to determine the effectiveness of breast feeding supports as a component of interventions to reduce postpartum smoking relapse.
