Results: Eighty-two per cent of women reported using supplements during their pregnancy, with the majority (67.7%) taking supplement brands containing both folic acid and iodine.
Supplement use was significantly higher among women in the highest household income category (30.8 vs 69.2%; P = 0.001).
Seventy-six per cent of the participants correctly identified NTDs to be associated with inadequate intake of folic acid, whereas only 40% correctly identified health problems associated with inadequate iodine intake.
Women’s knowledge of dietary sources of folic acid and iodine was limited.
