Official title
The Feasibility of Assessing the Prevalence of Rickets in Children
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
