The associations between MMF consumption profiles and vitamin D insufficiency and deficiency prevalence were studied using Pearson’s χ ² test.

^*The MMF consumption is expressed in times per month with a maximum of 1 time/d for each of the fifteen individual food types.

^†Missing data for one child living in Nuuk in the 4–<28 times/month consumption profile.
