Breastfeeding following in vitro fertilisation in Switzerland-Does mode of conception affect breastfeeding behaviour?

AIM: Breastfeeding has numerous advantages. Our aim was to investigate whether breastfeeding initiation and duration in women with pregnancies conceived through in vitro fertilisation differ from spontaneously conceived pregnancies. METHODS: This is a comparative cross-sectional study about breastfeeding behaviour performed at the Bern University Hospital including mothers of singletons conceived by in vitro fertilisation (n = 198) with or without gonadotropin stimulation between 2010 and 2016 (in vitro fertilisation group). They were compared to a population-based control group (n = 1421) of a randomly selected sample of mothers in Switzerland who delivered in 2014. RESULTS: A total of 1619 women were included in this analysis. Breastfeeding initiation rates were high, similar between the in vitro fertilisation group (93.4%) and the control group (94.8%). No increased risk of stopping breastfeeding earlier after in vitro fertilisation treatment compared to the control group could be found over the observational period of 12 months (HR = 1.00, 95% CI 0.83-1.20, P = .984). There was no difference in breastfeeding initiation or duration after gonadotropin-stimulated vs unstimulated in vitro fertilisation. CONCLUSION: In Switzerland, in vitro fertilisation treatments were not associated with earlier breastfeeding cessation. This result is reassuring for mothers undergoing in vitro fertilisation.

Baby-Friendly Hospital designation has a sustained impact on continued breastfeeding.

The Baby-Friendly Hospital (BFH) Initiative has led to an increase in breastfeeding rates and duration worldwide. But little is known about whether the beneficial effects persist beyond a facility's designation as a BFH. To investigate the association of BFH designation (current, former, and never) and compliance with Baby-Friendly (BF) practices on breastfeeding in Switzerland, this study combined nationwide survey data on breastfeeding with BFH monitoring data. In this cross-sectional study, 1,326 children were born in 34 current (N = 508), 28 former (N = 425), and 34 never designated BFHs (N = 393). We compared exclusive and any breastfeeding according to BFH designation over the first year of life, using Kaplan-Meyer Survival curves. Logistic regression models were applied to analyse breastfeeding prevalence, and Cox-regression models were used for exclusive (0-6 months) and continued (6-12 months) breastfeeding duration. Average duration of exclusive breastfeeding (13.1 weeks, 95% confidence interval [12.0, 17.4]) and any breastfeeding (32.7 weeks, 95% confidence interval [30.5, 39.2]) were the longest for babies born in currently accredited BFHs. Exclusive breastfeeding was associated with high compliance with monitored BF practices in current BFHs and with the number of BF practices experienced in all hospitals. Continued breastfeeding was significantly longer when babies were born in current BFHs (cessation hazard ratio 0.60, 95% confidence interval [0.42, 0.84]) or in former BFHs (cessation hazard ratio 0.68, 95% confidence interval [0.48, 0.97]). Overall, the results support continued investment into BFHs, because babies born in current BFHs are breastfed the most and the longest, whereas a former BFH designation shows a sustained effect on continued breastfeeding.
