Sex- and age-dependent effects of celiac disease on growth and weight gain in children with type 1 diabetes: Analysis of the type 1 diabetes Exchange Clinic Registry.

Concurrent CD impairs linear growth in T1D females at all stages of development and in young T1D males. Young females with CD have lower weights, but both sexes have similar weights by middle childhood. Children younger at CD onset remain shorter throughout childhood; males younger at CD onset have persistently lower weights. Long-term gluten restriction may restore weight gain and linear growth in children with CD and T1D.
