Prevalence and predictors of vitamin D deficiency in a nationally representative sample of Australian Aboriginal and Torres Strait Islander adults

Vitamin D deficiency (serum 25-hydroxyvitamin D (25(OH)D) concentration <50 nmol/l) is recognised as a public health problem globally. The present study details the prevalence and predictors of vitamin D deficiency in a nationally representative sample (n 3250) of Australian Aboriginal and Torres Strait Islander adults aged ≥18 years. We used data from the 2012-2013 Australian Aboriginal and Torres Strait Islander Health Survey (AATSIHS). Serum 25(OH)D concentrations were measured by liquid chromatography-tandem MS.

Vitamin D metabolites are lower with active Crohn’s disease and spontaneously recover with development of remission

We aimed to characterise vitamin D metabolism in a cohort of patients with active and inactive Crohn’s disease

High Vitamin D-Binding Protein Concentration, Low Albumin, and Mode of Remission Predict Relapse in Crohn's Disease

Associations between Vitamin D-binding protein, serum Vitamin D, and the calculated free Vitamin D concentrations with the risk of Crohn's disease flare

25-hydroxyvitamin D status of pregnant women is associated with the use of antenatal vitamin supplements and ambient ultraviolet radiation

Vitamin D deficiency in a predominantly white Caucasian cohort of pregnant women is less prevalent than has been reported in other studies

The current state of play of rodent models to study the role of vitamin D in UV-induced immunomodulation

Ultraviolet radiation (UVR) from sunlight is immunomodulatory and the main source of vitamin D for humans.

Serum 25-hydroxyvitamin D concentrations and cardiometabolic risk factors in adolescents and young adults

Associations between serum 25(OH)D concentrations and cardiometabolic risk factors from adolescence to young adulthood in the Raine Study

Asthma

One in eight children have asthma, a chronic disease of the airways in the lungs. It results in shortness of breath, chest tightness, wheezing and coughing.

High-dose intramuscular Vitamin D provides long-lasting moderate increases in serum 25-hydroxVitamin D levels and shorter-Term changes in plasma calcium

Intramuscular injection of a large bolus of Vitamin D effectively increases serum 25-hydroxyVitamin D levels without evidence of metabolic abnormality.

Prevalence and predictors of vitamin D deficiency in a nationally representative sample of Australian adolescents and young adults

Vitamin D deficiency is a public health concern worldwide. Maintaining vitamin D sufficiency during growth periods is essential. We aimed to determine the prevalence and predictors of vitamin D deficiency in Australian adolescents and young adults.
