Trial results for a study investigating cardiovascular health in postpartum mothers with conditions including obesity were posted on ClinicalTrials.gov on 2026-01-12. The Family Check-Up Heart intervention group showed a mean weight gain of 1.98 pounds from prenatal weight to 6 months postpartum, significantly less than the 11.5 pounds observed in the control group.
Background
Obesity, particularly maternal obesity, poses significant health challenges, including increased risks for cardiovascular complications and conditions like hypertension and diabetes during and after pregnancy. Postpartum weight retention is a common concern that can contribute to long-term health issues for mothers. Interventions that support mothers in managing their weight and promoting overall cardiovascular health in the postpartum period are crucial, especially when considering the health of young children in the family context.
Trial design
This completed pilot study, designated as Phase NA, enrolled 117 participants to examine cardiovascular health interventions for postpartum mothers and infants. The study focused on conditions including Maternal Obesity, Hypertension in Pregnancy, Pregnancy-Induced Hypertension, Diabetes, and Overweight. The trial adapted an existing evidence-based home visiting program, Family Check-Up, to create Family Check-Up Heart, which was compared against the standard Family Check-Up program (control).
Key results
The trial reported several key measurements comparing the Family Check-Up Heart intervention to the Family Check Up Control group:
- Change in Postpartum Weight Retention:
- Family Check Up Control group showed a mean change of -.73 pounds (Standard Deviation 9.9).
- Family Check-Up Heart group showed a mean change of .29 pounds (Standard Deviation 14.1).
- Weight at 6 Months Postpartum:
- Family Check Up Control group had a mean weight of 200.2 pounds (Standard Deviation 70.9).
- Family Check-Up Heart group had a mean weight of 202.1 pounds (Standard Deviation 58.3).
- Weight Change From First Measured Prenatal Weight to 6 Months Postpartum:
- Family Check Up Control group experienced a mean change of 11.5 pounds (Standard Deviation 15.2).
- Family Check-Up Heart group experienced a mean change of 1.98 pounds (Standard Deviation 18.9).
- Change in Self-reported Pre-pregnancy Weight to 6 Months Postpartum:
- Family Check Up Control group showed a mean change of 13.1 pounds (Standard Deviation 24.2).
- Family Check-Up Heart group showed a mean change of 4.7 pounds (Standard Deviation 24.2).
- Change in Blood Pressure From Post-delivery to 6 Months:
- For the first set of measurements:
- Family Check Up Control group showed a mean change of -1.76 mmHg (Standard Deviation 7.4).
- Family Check-Up Heart group showed a mean change of -1.4 mmHg (Standard Deviation 13.5).
- For the second set of measurements:
- Family Check Up Control group showed a mean change of -1.38 mmHg (Standard Deviation 6.8).
- Family Check-Up Heart group showed a mean change of -3.59 mmHg (Standard Deviation 13.2).
- For the first set of measurements:
What this means
The results suggest that the Family Check-Up Heart intervention may be effective in reducing postpartum weight retention compared to a standard control program. Mothers in the intervention group gained substantially less weight from their prenatal baseline to six months postpartum. This outcome is significant for addressing maternal obesity and its associated cardiovascular risks. While blood pressure changes were observed in both groups, the intervention group showed a greater reduction in one of the blood pressure measurements, indicating potential benefits for cardiovascular health beyond weight management alone. These findings from a pilot study warrant further investigation into the Family Check-Up Heart program's broader impact on maternal and child health.
