The influence of sunlight exposure and sun protecting behaviours on allergic outcomes in early childhood

The 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.

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.

In “high-risk” infants with sufficient vitamin d status at birth, infant vitamin D supplementation had no effect on allergy outcomes: A randomized controlled trial

Early infancy oral vitamin D supplementation does not appear to reduce the development of early childhood allergic disease

Low-dose UV radiation before running wheel access activates brown adipose tissue

When combined with physical activity, low-dose UVR may more effectively limit adiposity and modulate metabolic and immune pathways in iBAT

Are low sun exposure and/or Vitamin D risk factors for type 1 diabetes

Evidence supports that higher sun exposure and/or vitamin D sufficiency in pregnancy, or supplementation in early life, decreases type 1 diabetes risk

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

Sun exposure and its effects on human health: Mechanisms through which sun exposure could reduce the risk of developing obesity and cardiometabolic dysfunction

The cardiometabolic protective effects of ultraviolet radiation and mechanistic pathways through which ultraviolet radiation could be beneficial.

Vitamin D and allergic airway disease shape the murine lung microbiome in a sex-specific manner

Maintaining sufficient vitamin D is necessary for optimal lung health, and vitamin D may modulate the lung microbiome in a sex-specific fashion

Dietary Vitamin D Increases Percentages and Function of Regulatory T Cells in the Skin-Draining Lymph Nodes and Suppresses Dermal Inflammation

Dietary vitamin D3 increased the suppressive activity of regulatory T cells in the skin-draining lymph nodes, which are poised to suppress dermal inflammation

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
