简要总结
The goal of this randomized clinical trial is to evaluate the effectiveness of SmartMom, a text messaging-based mobile health program for prenatal education. The main questions are to determine if healthy pregnant people receiving SmartMom messages that promote health behaviours in pregnancy versus messages that don't provoke behaviour change have improvement in:
- knowledge about healthy pregnancy and birth
- standardized measures of depression, anxiety, and fear of childbirth
- adoption of positive health behaviours in pregnancy
- maternal, fetal, and newborn outcomes
Participants in the intervention group will receive three evidence-based text messages per week, plus optional supplemental messages on topics relevant to them, throughout pregnancy.
The control group will receive general interest messages on pregnancy-related topics that are not promoting behaviour change.

干预措施: Control text messaging (Behavioral)
结局指标
主要结局
Change in weight during pregnancy
时间窗: Enrollment, 38 weeks gestation

Attendance at prenatal care visits through pregnancy
时间窗: 38 weeks gestation
Rates of attendance at prenatal care appointments in adherence to Canadian guidelines. These include self-reported data as well as data from provincial prenatal registries and the Canadian Hospital Discharge Database linked via personal health number, provided as part of the consenting procedure.
