Abstract
OBJECTIVE: Mobile health (mHealth) safe sleep messaging increases rates of safe sleep. Bedsharing is more common among breastfeeders. Advice to not bedshare may negatively impact breastfeeding. We compared the impact of safe sleep or breastfeeding mHealth messaging on bedsharing and breastfeeding at 2 to 5 months. METHODS: This is a secondary analysis of mothers who initiated breastfeeding from a cluster randomized clinical trial of mHealth messaging for safe sleep or breastfeeding. A multi-ethnic sample of 1600 mothers was recruited from 16 US birth hospitals and surveyed at 2 to 5 months regarding the previous 2 weeks' breastfeeding and bedsharing practices. Data on 997 mothers who initiated breastfeeding were analyzed with multivariable generalized estimating logistic regression models to examine the association of mHealth messaging with infant care practices. RESULTS: Overall, exposure to breastfeeding versus safe sleep messaging was not associated with a difference in any breastfeeding at 2 to 5 months (69.3% vs 65.5%, respectively; adjusted odds ratio [aOR] = 1.33 [95% confidence interval, 0.91, 1.94]). Women with shorter planned duration of breastfeeding who received breastfeeding messaging had increased odds of breastfeeding at 2 to 5 months (50% vs 31%; aOR 3.13 [95% CI, 1.47, 6.65]). Mothers who received safe sleep messaging had lower rates of bedsharing overall when compared to breastfeeding messaging (24.8% vs 35.2%; aOR = 0.58 [95% CI, 0.44, 0.78]). CONCLUSIONS: In this large multi-ethnic US sample, receipt of safe sleep mHealth messaging was associated with lower rates of bedsharing without negatively impacting breastfeeding rates. Future research should focus on continued development of interventions to improve adherence to both safe sleep and breastfeeding recommendations.
