Study design
The Mikhuna randomized trial assigned 215 pregnant women in Ecuador to usual care or a culturally adapted food-support program from 12 weeks of pregnancy until birth. Weekly deliveries included eight eggs, 500 g of fish and a variety of fruits and vegetables, alongside behavior-change support.
Findings
The intervention group more often met the dietary-diversity threshold (74.5% versus 55.8%; p=0.004). The paper reported growth differences in the corpus callosum and gangliothalamic ovoid (GTO). A Washington University release on Newswise says only the GTO result remained significant after multiple-comparison adjustment; the corpus-callosum difference did not.
Limits and disclosures
Ultrasound-measured fetal anatomy does not show that children later have better cognition. The intervention bundled food provision and counseling, so it cannot isolate individual foods. The paper reports a randomized trial; longer follow-up is needed to establish developmental consequences.
