  1. Based on Irish RDAs [28]. Insufficient data to provide recommendations for: ß Carotene and other carotenoids Pantothenic acid, Vitamin K, Magnesium, Molybdenum, Manganese, Biotin, Fluoride, Chloride, Chromium and Vitamin E. Definite underreporters excluded (Goldberg Ratio ≤0.9). The population compliance method was used to determine frequency of compliance with RDAs [35]. Chi-squared tests used to compare frequency of compliance with RDAs between the control and intervention groups. *N/A as zero women in the intervention group met the RDA for vitamin D in trimesters 1 or 2
