Strongest in Recency (100). Held back by Sample size (10).
Solid mix of RCTs with some methodological gaps.
Few independent replications; results not yet robust.
Small combined sample; treat as preliminary.
Studies agree on direction of effect.
Most studies are recent (last 2-3 years).
No quantified outcomes yet. Once we have studies with measurable endpoints, you will see per-outcome magnitude here.
BHIP intervention offspring had fewer total behavior problems reported by mothers (η²p=0.09) and partners (η²p=0.17) compared with controls.
The BHIP prenatal diet-and-exercise intervention (high-protein energy-controlled diet with cottage cheese, Greek yogurt, low-fat milk, nutritional counseling, and walking program) reduced mother- and partner-reported externalizing behavior problems in 22-month-old offspring relative to usual pregnancy care.
Offspring exposed to the BHIP intervention showed reductions in internalizing behavior problems as reported by mothers (η²p=0.08) and partners (η²p=0.13).
