Brief Summary:
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.
Detailed Description:
The Puget Sound Pediatric Research Network (PSPRN) is a practice-based research network of pediatricians in the Puget Sound area and at the University of Washington and Children's Hospital and Regional Medical Center. The network has extensive experience in conducting large studies on contentious issues that are pertinent to children, their parents, and primary care providers. In 2004, vitamin D supplementation was recommended for all exclusively breastfed infants. This recommendation was based on sporadic reports over the last 30 years of vitamin D deficient rickets in infants and toddlers who have been exclusively breastfed. The recommendation has been controversial because it might undermine efforts to promote breastfeeding, and because the prevalence of rickets in these patients is unknown. PSPRN proposes to conduct a preliminary study to determine the feasibility of a larger planned project by the network to determine the prevalence of rickets in breastfed infants and toddlers who do not receive supplemental vitamin D. Systematic surveys will be conducted in PSPRN practices to determine current levels and trends in vitamin D supplementation. Current practices of PSPRN pediatricians regarding supplementation, and their effect on parents, will also be assessed. The utility of a serum alkaline phosphatase level as a screening test for vitamin D deficient rickets will be determined in the proposed study by obtaining levels on approximately 300 patients, 6-15 months old, seen by PSPRN practitioners, who have been breastfed. In addition to assessing possible methodologies for the larger project, the preliminary study is designed to yield standalone results with important implications.
