Myopia is associated with lower vitamin D status in young adultsThe aim of this study was to investigate the link between vitamin D levels in the blood and short-sightedness in young adults.

Ultraviolet radiation exposure and serum vitamin D levels in young childrenThis paper examined the link between UV exposure and vitamin D production in young children to determine how long it takes for sun exposure to affect serum...

Vitamin D deficiency causes airway hyperresponsiveness and increases airway smooth muscle mass in the lungs of female BALB/c miceWe tested whether there is a causal association between vitamin D deficiency, airway smooth muscle (ASM) mass, and the development of airway hyperresponsiveness

Maternal vitamin D levels during pregnancy and offspring eating disorder risk in adolescenceThis is the first study to link low gestational vitamin D to increased eating disorder risk in female offspring of Caucasian mothers.

Topical 1,25-dihydroxyvitamin D3 subverts the priming ability of draining lymph node dendritic cellsThe active form of vitamin D, 1,25-hydroxyvitamin D(3) [1,25(OH)(2)D(3)] is produced in skin following exposure to sunlight

Exposure to sunlight could reduce asthmaAustralian researchers have found that exposure to measured doses of ultraviolet light, such as sunlight, could reduce asthma.

Increased levels of solar radiation are associated with reduced type-2 diabetes prevalence: A cross-sectional study of Australian postcodesType-2 diabetes is a leading cause of death and disability. Emerging evidence suggests that ultraviolet radiation or sun exposure may limit its development. We used freely available online datasets to evaluate the associations between solar radiation and type-2 diabetes prevalence across Australia.

In “high-risk” infants with sufficient vitamin d status at birth, infant vitamin D supplementation had no effect on allergy outcomes: A randomized controlled trialEarly infancy oral vitamin D supplementation does not appear to reduce the development of early childhood allergic disease

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

The influence of sunlight exposure and sun protecting behaviours on allergic outcomes in early childhoodThe dramatic rise in allergic disease has occurred in tandem with recent environmental changes and increasing indoor lifestyle culture. While multifactorial, one consistent allergy risk factor has been reduced sunlight exposure. However, vitamin D supplementation studies have been disappointing in preventing allergy, raising possible independent effects of ultraviolet (UV) light exposure.
