Abstract

Aim: We aimed to determine the prevalence of and factors associated with maternal use of nicotine products in relation to breastfeeding.

Methods: Nicotine use 3 months postpartum was determined in the Scandinavian PreventADALL mother-child birth cohort study recruiting 1837 women from 2014 to 2016. Electronic questionnaires at 18 weeks pregnancy and 3 months postpartum provided information on snus use, smoking or other nicotine use, infant feeding and socio-economic factors. The risk of nicotine use in relation to breastfeeding was analysed with logistic regression.

Results: Overall, 5.6% of women used snus (2.9%), smoked (2.7%) or both (n = 2) 3 months postpartum, while one used other nicotine products. Among the 1717 breastfeeding women, 95.1% reported no nicotine use, while 2.4% used snus, 2.5% smoked and one dual user. Compared to 3.7% nicotine use in exclusively breastfeeding women (n = 1242), the risk of nicotine use increased by partly (OR 2.26, 95% CI 1.45-3.52) and no breastfeeding (OR 4.58, 95% CI 2.57-8.21). Nicotine use before (14.5% snus, 16.4% smoking) or in pregnancy (0.2% snus, 0.4% smoking) significantly increased the risk of using nicotine during breastfeeding.

Conclusion: Few breastfeeding women used snus or smoked 3 months postpartum, with increased risk by nicotine use before or during pregnancy.

Keywords: birth cohort; breastfeeding; maternal smoking; pregnancy; snus use.
