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.
To 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.
Autism 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.

Felix was one of 195 children to take part in Dr Debbie Palmer’s research into sunlight exposure, vitamin D and eczema.
For decades Aussies have been told to minimise sun exposure to prevent skin cancer - now researchers at Telethon Kids are challenging that message.
The Kids researcher Dr Shelley Gorman has received a Healthway grant to develop an online tool to promote safe sun behaviours to teenagers.
Researchers at The Kids Research Institute Australia are continuing to hone in on the effects of ultraviolet radiation and vitamin D on the immune system.
The D-Light program, set up in 2014, aims to shed light on the amount of sun exposure that will promote good health in children and adolescents.
Leading international and national experts will gather at The Kids Research Institute Australia on Friday for a D-Light Research Symposium.
