A parallel design, proof-of-concept randomized control trial was conducted with 65 mother-infant dyads (32 randomized to intervention, 33 randomized an IBH attention control focused on promoting healthy mental health), in which the majority identify as Black (80%) and low income (91% receiving Medicaid). Participants and assessors were masked to treatment condition. Outcomes included feasibility (enrollment), acceptability (retention and adherence), and conditional weight gain (CWG), an indicator of rapid weight gain.
The intervention was feasible (90% of eligible families enrolled) and acceptable (89% of families retained), with 81% receiving ≥3 of 4 treatment sessions. A medium effect was found on CWG (d = -0.54 post-treatment, d = -0.57 follow-up), with the infants in the treatment group showing significantly lower CWG (mean = -0.27, 95% CI, -0.63, 0.09) compared to the control group (mean = 0.29, 95% CI, -0.17, 0.76) at 9 months (p = .04).
This study demonstrates the feasibility of implementing a responsive parenting obesity prevention intervention within primary care. Delivery in pediatric primary care is advantageous for implementation and reaching at-risk populations. The preliminary effects on CWG are promising and support testing in a larger trial.
