Main Outcomes and Measures The primary outcome was a plasma 25(OH)D concentration of 75 nmol/L or greater in 97.5% of infants at 3 months. Secondary outcomes included 25(OH)D concentrations of 75 nmol/L or greater in 97.5% of infants at 6, 9, and 12 months; 25(OH)D concentrations of 50 nmol/L or greater across all times; growth; and whole body and regional bone mineral content. Data were analyzed by intention to treat using available data, logistic regression, and mixed-model analysis of varianc...

Abstract Background Few normative data exist for routine clinical chemistry in healthy term infants, that is, during a time of rapid development. Biochemical markers are significantly affected by these physiological changes and the lack of appropriate reference intervals may impede diagnostics in infants. Objective To define reference intervals for calcium, phosphate, creatinine, and alkaline phosphatase in infants from 1 to 12 months of age. Design and methods This was an unblinded secondary an...

Aim The aim of this study was to evaluate the uptake of a free vitamin D infant prescription programme and to determine the incidence of nutritional rickets. Methods This was a retrospective cohort study of infants from Quebec, Canada, involving term infants born between 1998 and 2008 and covered by the public insurance programme. Data were extracted from the Quebec Pregnancy Cohort. Predictors of programme participation were identified through logistic regression. Results A total of 123 018 inf...

Abstract Background Although no gold standard exists, liquid chromatography tandem mass spectrometry (LC–MS/MS) is a precise and accurate method for the analysis of plasma 25-hydroxyvitamin D (25(OH)D). Immunoassays are more readily available and require small volume sampling, ideal for infant testing. The objective was to compare two commercially available immunoassays for measuring circulating 25(OH)D concentration in infant plasma against LC–MS/MS. Methods Capillary blood samples from 103 inf...

The biological equivalency of ergocalciferol (D2) and cholecalciferol (D3) has been debated; several comparisons have appeared in the adult literature but are scarce in pediatrics. The objective of this study was to compare increases in plasma 25-hydroxyvitamin D [25(OH)D] concentrations and attainment of 50 and 75 mol/L status cutoffs following 3 mo of daily supplementation with D2 compared with D3. Healthy, breast-fed, 1-mo-old infants (n = 52) received 10 μg (400 ic) of either D2 or D3 daily....

Objective To examine the temporal and dose-related effects of glucocorticoids (GCs) on body mass index (BMI) in children with rheumatic diseases. Methods Children initiating GCs for a rheumatic disease (n = 130) were assessed every 3 months for 18 months. BMI, weight, and height Z score trajectories were described according to GC starting dosage in prednisone equivalents: high (≥1.0 mg/kg/day), low (<0.2 mg/kg/day to a maximum of 7.5 mg/day), and moderate (between high and low) dosage. The impac...

Abstract Objective To determine if there is an association between lower socio-economic status (SES) and decreased utilization of diabetes educators or inferior diabetes control as measured by both glycated hemoglobin (A1C) and number of diabetes-related hospitalizations. Patients and Methods Our cohort consisted of all children aged Results There were 2500 contacts made by 353 children (mean age 12.3 years, mean diabetes duration 5.4 years, mean A1C 8.8%). Even though the number of educator con...
