The higher frequency category used in the latent class model is listed next to each FFQ item
As a percentage of total milk (breast and formula) feedings at 9 months
Dietary latent classes: BFV=breastfed, fruits and vegetables, BLV=breastfed, low variety, FFV=formula, fruits and vegetables, FLV=formula, low variety, FHED=formula, high energy density
