Study to Assess the Use of a Simple Lab Test to Screen for Rickets in Children

Completed

Conditions studied: Rickets

In brief

Some experts recommend that all breastfed babies receive supplemental vitamin D. The purpose of this study is to determine the rate of vitamin D use in breastfed babies, the recommendations of pediatricians regarding vitamin D, and the impact on these recommendations on parental choice of vitamin D. In addition, in preparation for a large study to see how many breastfed children who don't receive supplemental vitamin D have rickets, in this study we will determine if a simple blood test, an alkaline phosphatase level, could be used to screen for rickets. Parents of children 6-23 months old are eligible to complete feeding surveys and children 6-15 months old who were breastfed for at least the first six months of life and didn't routinely receive vitamin D are eligible for alkaline phosphatase levels. We postulate that most breastfed babies don't receive supplemental vitamin D, and that alkaline phosphatase levels will only be abnormal in a few babies who will have evidence on x-ray of rickets.
