Summary

This trial is testing a breastfeeding self-efficacy intervention to improve breastfeeding outcomes and lower blood pressure in women with hypertensive disorders of pregnancy.

Who is the study for?
This trial is for women over 18 who've given birth to a single baby at or after 34 weeks, plan and have started breastfeeding, speak English or French, have health coverage (RAMQ/OHIP), can use a cellphone with internet for BP monitoring and live near Montreal/Kingston. It's not for those with conditions that prevent breastfeeding, severe mental illness, substance abuse issues, COVID-19 during hospitalization or specific neonatal complications.
What is being tested?
The study tests if boosting mothers' confidence in breastfeeding (breastfeeding self-efficacy) can help lower blood pressure postpartum among women who had high blood pressure disorders during pregnancy. The goal is to see if this intervention could be part of heart disease risk reduction programs.
What are the potential side effects?
Since the intervention focuses on educational support rather than medication or medical procedures, there are no direct side effects from the treatment itself. However, general challenges related to breastfeeding may occur.
