Dietary supplement use immediately before and during pregnancy in Norwegian women with eating disorders.

Objective: Many pregnant women use dietary supplements. Little is known about dietary supplement use during pregnancy in women with eating disorders.
Method: We examined dietary supplement use in 37,307 pregnant women, from the Norwegian Mother and Child Cohort Study.
Results: Dietary supplement use during pregnancy was as follows: 91.2% of women with anorexia nervosa, 92.2% of women with bulimia nervosa, 93.2% of women with eating disorder not otherwise specified-purging subtype (EDNOS-P), 90.6% of women with binge eating disorder, and 93.5% of the women without eating disorders. Between group differences were not statistically significant. After adjusting for covariates, women with EDNOS-P were more likely to take iron containing supplements (p ≤ .04).
Discussion: Overall dietary supplement use in this sample is similar in women with and without eating disorders.
