• Objectives Fetal alcohol spectrum disorders are more common in disadvantaged populations. Environmental factors, like suboptimal nutrition, may potentiate the developmental effects of prenatal alcohol exposure. To evaluate the impact of micronutrients, including choline, on reduction of effects of exposure, we examined timing and dose of alcohol and effects of nutritional supplementation at two OMNI-Net sites in Western Ukraine that included high and low risk individuals. Methods Alcohol-using and nondrinking women were randomized to one of three multivitamin/mineral supplement groups: none, multivitamins/minerals (MVM), and multivitamin/minerals plus choline. Children (N = 367) were tested at 6 months with the Bayley Scales of Infant Development (2nd ED) yielding standard scores for Mental Development Index (MDI), Psychomotor Development Index (PDI) and Behavior. Results Generalized linear modeling was used: (1) for factorial analysis of effects of alcohol group, multivitamin/minerals, and choline supplementation; and (2) to examine the relationship between amount and timing of alcohol (ounces of absolute alcohol/day [ozAA/day] peri-conception and on average in the second trimester) and MVM supplementation on developmental outcomes while controlling sex, social class, and smoking. MDI was significantly impacted by peri-conceptual alcohol dose ( χ ( 1 ) 2 = 8.54 , p  < .001) with more alcohol associated with lower scores and males more negatively affected than females ( χ ( 3 ) 2 = 11.04 , p  < .002). Micronutrient supplementation had a protective effect; those receiving supplements performed better ( χ ( 1 ) 2 = 8.03 , p  < .005). The PDI motor scores did not differ by group but were affected by peri-conceptual alcohol dose ( χ ( 1 ) 2 = 4.17 , p  < .04). Conclusions for Practice Multivitamin/mineral supplementation can reduce the negative impact of alcohol use during pregnancy on specific developmental outcomes.
