The prevalence of multiple sclerosis follows a latitude gradient, with increased disease at higher latitudes.
Background: Epidemiological evidence shows that people with thicker, or higher stage, melanomas have lower vitamin D status compared to those with thinner...
There are indications that risk factors for BCC may differ according to the anatomic site of the tumour but this is not well understood.
Adults living in the sunny Australian climate are at high risk of skin cancer, but vitamin D deficiency (defined here as a serum 25-hydroxyvitamin D...
The dramatic rise in early childhood allergic diseases indicates the specific vulnerability of the immune system to early life environmental changes.
Sun exposure is associated with several ophthalmic diseases, including pterygium which may develop in adolescence.
Birth cohort studies provide an invaluable resource for studies of the influence of the fetal environment on health in later life.
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.
There is a greater prevalence of multiple sclerosis (MS), a neurological autoimmune condition, in populations living further from the equator, hypothesised to be due to reduced sunlight exposure. There exists a proven sunlight surrogate therapy for dermatological inflammatory conditions, in the form of narrowband NB-UVB phototherapy. Yet, there is a paucity of randomized trials of the therapeutic delivery of NB-UVB beyond dermatology for conditions with a systemic inflammatory component.
Low vitamin D intake and prevalence of serum 25-hydroxyvitamin D concentration <50 nmol/L among Aboriginal and Torres Strait Islander peoples highlight a need for public health strategies to improve vitamin D status. Since few foods contain naturally occurring vitamin D, food fortification could be a suitable strategy. We aimed to model vitamin D food fortification scenarios among Aboriginal and Torres Strait Islander peoples.
