Seasonal variation of relapse rate in multiple sclerosis is latitude dependent

We demonstrate a latitude-dependent relationship between seasonal UVR trough and relapse onset probability peak independent of location-specific UVR levels

Sun exposure and vitamin D status as northeast asian migrants become acculturated to life in Australia

Targeted public health approaches are required to manage the high prevalence of vitamin D deficiency in migrants retaining a traditional lifestyle

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

Analytical bias in the measurement of plasma 25-hydroxyvitamin D concentrations in infants

To our knowledge, this is the first study to show that the reported 25(OH)D concentration may be influenced by both age and assay type

Effects of UVR exposure on the gut microbiota of mice and humans

Both human and murine studies report that multiple exposures to sub-erythemal UV radiation can increase the diversity of the gut microbiome

Sun exposure: An environmental preventer of metabolic dysfunction?

Emerging preclinical findings suggest that some sun exposure is necessary for optimal metabolic health

Systematic Review of the Effects of Ultraviolet Radiation on Markers of Metabolic Dysfunction

Here we review the metabolic effects of exposure to ultraviolet radiation, focusing on the effects of phototherapies

Associations between sun exposure, skin pH, and epidermal permeability in pregnancy: A longitudinal observational study

Little is known about how sun exposure may affect the maternal skin barrier during pregnancy when many hormonal and physiological changes occur. In this longitudinal observational study, 50 pregnant women were recruited at 18-24 weeks' gestation, 25 in summer-autumn, and 25 in winter-spring. At three time points in pregnancy at 18-24, 28-30, and 36-38 weeks' gestation, participants completed a validated sun exposure questionnaire and had skin permeability and surface pH measured on the volar forearm.
