Clinical, research, and public health implications of poor measurement of Vitamin D status

New initiatives to develop a standard reference method and the assignment of "true" values to samples provide a solution to these problems.

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

Ultraviolet radiation, Vitamin D and the development of obesity, metabolic syndrome and type-2 diabetes

Emerging findings suggest a protective role for ultraviolet radiation (UVR) and sun exposure in reducing the development of obesity and cardiometabolic dysfunction, but more epidemiological and clinical research is required that focuses on measuring the direct associations and effects of exposure to UVR in humans.

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

Vitamin D and parathyroid hormone in insulin resistance of abdominal obesity: Cause or effect?

The objective was to examine whether there were causal links between vitamin D status, parathyroid hormone, insulin resistance.

Calcium and Vitamin D for obesity: review of randomized controlled trials

Obesity often coexists with low calcium intake and vitamin D insufficiency.

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

Predictors of vitamin D-containing supplement use in the Australian population and associations between dose and serum 25-hydroxyvitamin D concentrations

The prevalence of vitamin D-containing supplement use was generally low in the Australian population, particularly for single vitamin D supplements

Ultraviolet irradiation of skin alters the faecal microbiome independently of vitamin D in mice

Skin exposure to ultraviolet radiation alters the faecal microbiome, and further investigations to explore the implications of this in health and disease are warranted

Vitamin D is crucial for maternal care and offspring social behaviour in rats

These data highlight that early life levels of vitamin D are an important consideration for maternal behavioural adaptations as well as offspring neuropsychiatry
