Vitamin D supplementation, moderate sun exposure, and control of immune diseasesThere is considerable debate about the benefits of vitamin D supplementation for multiple sclerosis, allergic asthma, and type 1 diabetes.

Gene-vitamin D interactions on food sensitization: A prospective birth cohort studyIt has been hypothesized that vitamin D deficiency (VDD) contributes to the development of food sensitization (FS) and then food allergy.

Vitamin D deficiency causes deficits in lung function and alters lung structureThe prevalence of vitamin D deficiency is increasing and has been linked to obstructive lung diseases including asthma and chronic obstructive pulmonary disease

Expression of CYP24A1 and other multiple sclerosis risk genes in peripheral blood indicates response to vitamin D in homeostatic and inflammatory conditionsAlthough genetic and epidemiological evidence indicates vitamin D insufficiency contributes to multiple sclerosis (MS), and serum levels of vitamin D increase on treatment with cholecalciferol, recent metanalyses indicate that this vitamin D form does not ameliorate disease. Genetic variation in genes regulating vitamin D, and regulated by vitamin D, affect MS risk.

Targeted Teacher Education to Improve Primary Preservice Teachers’ Knowledge and Understanding of UV and Effective Sun Protection Measures for ChildrenTeachers are responsible for children at school during peak ultraviolet (UV) times of the day. It is paramount that teachers have knowledge and understanding of UV to effectively protect themselves and their students. The aim of this pilot study was to investigate the effect of a short intervention on preservice teachers’ sun protective behaviours, knowledge and perceived skill to teach sun safety.

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

Time spent outdoors through childhood and adolescence - assessed by 25-hydroxyvitamin D concentration - and risk of myopia at 20 yearsTo investigate the relationship between time spent outdoors, at particular ages in childhood and adolescence, and myopia status in young adulthood using serum 25-hydroxyvitamin D [25(OH)D] concentration as a biomarker of time spent outdoors. Participants of the Raine Study Generation 2 cohort had 25(OH)D concentrations measured at the 6-, 14-, 17- and 20-year follow-ups. Participants underwent cycloplegic autorefraction at age 20 years, and myopia was defined as a mean spherical equivalent -0.50 dioptres or more myopic. Logistic regression was used to analyse the association between risk of myopia at age 20 years and age-specific 25(OH)D concentrations. Linear mixed-effects models were used to analyse trajectory of 25(OH)D concentrations from 6 to 20 years.

Developmental vitamin D deficiency increases foetal exposure to testosteroneAutism spectrum disorder (ASD) is a group of neurodevelopmental disorders which are more common in males. The 'prenatal sex steroid' hypothesis links excessive sex-steroid exposure during foetal life with the behavioural differences observed in ASD. However, the reason why sex steroid exposure may be excessive remains unclear. Epidemiological studies have identified several environmental risk factors associated with ASD, including developmental vitamin D (DVD) deficiency.
