Vitamin D C3-epimer levels are proportionally higher with oral vitamin D supplementation compared to ultraviolet irradiation of skin in mice but not humans

The proportion of 25(OH)D3 that undergoes epimerization is greater with oral vitamin D3 supplementation than exposure to UVR in mice, but not in humans

Developing an Online Tool to Promote Safe Sun Behaviors With Young Teenagers as Co-researchers

Despite education about the risks of excessive sun exposure, teenagers in Australia are sun-seeking, with sunburn common in summer. Conversely, some regular (time-limited) exposure to sunlight (that avoids sunburn) is necessary for vitamin D and healthy bones and other molecules important for immune and metabolic health. New interventions are thus required to better support teenagers to make healthy and balanced decisions about their sun behaviors.

A Gender Lens on User Quality Ratings From Young Teenagers Assessing the Sun Safe App: Comparing Responses From Co-researchers and Participants of Pilot Intervention Studies

We developed the iOS smartphone app Sun Safe to support healthy sun practices in young teenagers (aged 12-13 years). The production involved co-design with young co-researchers (ie, aged 12-13 years) with a health message of using sun protection when the UV index is ≥3. Important features include real-time and location-specific weather data on the UV index and gamified educational content.

Myopia is associated with lower vitamin D status in young adults

The aim of this study was to investigate the link between vitamin D levels in the blood and short-sightedness in young adults.

Incidence of nonmelanoma skin cancer in relation to ambient UV radiation in white populations, 1978-2012 empirical relationships

This paper examined dose-response relationships between ambient UVR levels and NMSC incidence at the population level.

Genome-wide association study of vitamin D levels in children: replication in the Western Australian Pregnancy Cohort (Raine) study

This genome-wide association study (GWAS) utilises data from the Western Australian Pregnancy Cohort (Raine) Study for 25-hydroxyvitamin D (25(OH)D) levels...

Gene-vitamin D interactions on food sensitization: A prospective birth cohort study

It has been hypothesized that vitamin D deficiency (VDD) contributes to the development of food sensitization (FS) and then food allergy.

The relationship between ambient ultraviolet radiation (UVR) and objectively measured personal UVR exposure dose is modified by season and latitude

Season and latitude modify the relationship between ambient ultraviolet radiation and personal ultraviolet radiation exposure

Shining the Light on Sunshine: A systematic review of the influence of sun exposure on type 2 diabetes mellitus-related outcomes

This review highlights significant gaps in research pertaining to sun exposure and type 2 diabetes mellitus related outcomes

Ultraviolet radiation suppresses obesity and symptoms of metabolic syndrome independently of vitamin D

UVR or sunlight exposure may be an effective means of suppressing the development of obesity and MetS, through mechanisms that are independent of vitamin D
