Background/aim: Osteoporosis is a known complication in adults with type 1 diabetes mellitus (T1DM), but whether the bones are affected in children and adolescents with T1DM remains controversial. The study aim was to evaluate bone mineral density (BMD) in children and adolescents with T1DM and identify risk factors associated to lower BMD.Method: In a single-center cohort of children and adolescents with T1DM, BMD was examined by dual-energy X-ray absor...

Context: Severe vitamin D deficiency may lead to myopathy in adults. Little is known about vitamin D and muscle strength in children.Objective: To test whether hand grip strength (HGS) in 5-year-old-children associates with serum 25-hydroxyvitamin D (s-25OHD) from pregnancy to 5 years.Methods: Observational study in the population-based Odense Child Cohort, Denmark. At 5 years, anthropometrics, body fat percentage by skin fold meas...

Background: Vitamin D may have cardio-protective properties due to its biological actions. In children, observational studies linking actual vitamin D level and blood pressure have yielded conflicting results. Whether early life vitamin D exposure may elicit a programming effect on later systolic blood pressure (SBP) and diastolic blood pressure (DBP) needs further investigation.Objective and hypotheses: We investigated whether higher levels of cord 25-h...

Background: Vitamin D deficiency can cause rickets and impaired bone growth in infants. In India, randomization to higher vitamin D supplementation doses in pregnancy led to decreased anterior fontanelle and increased head circumference at 0 and 9 months.Objective and hypotheses: To investigate the impact of cord 25-hydroxyvitamin D (25(OH)D) concentrations on cranial measures.Method: In a Danish prospective birth cohort of 2549 mo...

Background: Vitamin D deficiency in children clinically manifests as rickets causing growth impairment and bowing of the long bones, potentially increasing the ratio between crown-rump length and length (CRL:L) or sitting height and height (SH:H).Objective and hypotheses: We investigated whether CRL:L in 19-months-olds and SH:H in 36-months-olds were lower with higher cord 25hydroxyvitamin D (25OHD).Method: Participants were includ...

Background: Animal studies suggest a role of vitamin D in fetal lung development although not studied in preterm animals.Objective and hypotheses: We tested the hypothesis that vitamin D depletion does not aggravate respiratory insufficiency in preterm rat offspring. Furthermore, the effects of vitamin D depletion on growth and lung surfactant were investigated.Method: Female Sprague-Dawley rats were randomly assigned low vitamin D...
