The comparison of access to an eHealth resource to current practice on mother and co-parent teamwork and breastfeeding rates: A randomized controlled trial

•Partner and co-parent support has been found to increase breastfeeding outcomes.•Web-based breastfeeding educational interventions increase breastfeeding rates.•Involving both parents in breastfeeding interventions increases breastfeeding rates.•eHealth resources increase breastfeeding knowledge and infant feeding attitude.•eHealth resources are an accessible way of providing breastfeeding education. Breastfeeding rates are suboptimal, putting mothers and their infants’ health at risk. One modifiable risk factor amenable to intervention is partner support. Having women work as a team with their co-parents to meet their breastfeeding goals has been found to improve breastfeeding outcomes. eHealth resources have been found to be accessible and feasible ways to provide breastfeeding education yet, the best way to design breastfeeding interventions for mothers and their co-parents is not known. To compare two study conditions to determine: (1) which way is more effective to provide breastfeeding education to women and their co-parents on increasing breastfeeding rates and associated secondary outcomes, such as breastfeeding knowledge, attitude, self-efficacy and overcoming challenges; (2) the difference in co-parenting and partner support between the study groups; (3) how parents in both groups preferred to access breastfeeding information; and (4) the groups’ satisfaction with the eHealth resource that was provided. This study used a randomized controlled trial design (Clinicaltrials.org #NCT03492411). Participants were randomly allocated to study groups with concealed opaque envelopes by a blinded research assistant. Participants in Study Condition #1 (SC1) accessed a previously created, online e-Health resource, in addition to other generally available resources they could access in the community; participants in Study Condition #2 (SC2) accessed only the generally available resources. Participants were recruited in health care providers’ offices and services for expectant parents in Ontario and via social media throughout Canada. Expectant women (n = 113) and their co-parents (n = 104) were enrolled. After eligibility was determined, consents obtained and baseline surveys completed, group allocation was conducted. SC1 had a virtual meeting with a research assistant to review the eHealth resource. Weekly emails were sent to all participants for 6 weeks as reminders. Follow-up data were electronically collected from mothers and co-parents at 2 weeks post en
