Among the 21 studies in Hypertension by Northwestern University, from their registry updates:
The purpose of this intervention is to help new mothers who had elevated blood pressure during pregnancy become more physically active after birth. The investigators will connect data from FitBits to the electronic health record. Women will then get weekly messages with feedback and goals to help them stay active. The investigators will test if the intervention improves step counts and blood pressure after pregnancy. The investigators will also test if the intervention is feasible and enjoyed by postpartum women.

Start is estimated for Apr 2027; primary completion for Apr 2028, 12 months later.
Of 1,403 non-industry interventional studies with no phase under Hypertension, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 41. This study's planned 12 months is below that.
Counting every sponsor, half of 1,498 studies reached it within 23 months; a quarter within 10 and three quarters within 41.
