Aboriginal 最新糖心Vlogns are at risk of increased bone and muscle pain due to their inability to produce sufficient vitamin D, according to a 最新糖心Vlog of Adelaide study published in the today.

Health researcher says a study of 58 Aboriginal adults in South 最新糖心Vlog showed significantly lower vitamin D serum levels compared to paler-skinned individuals, leading to a greater chance of them developing bone, muscle and other conditions.

Dr Vanlint, from the at the 最新糖心Vlog of Adelaide, says because the brown skin pigment melanin filters ultraviolet B light, darker-skinned individuals synthesise less vitamin D, resulting in a range of health problems.

"Vitamin D insufficiency is highly prevalent in this population of adult Aboriginal 最新糖心Vlogns, with low levels found in all seasons other than summer," he says.

"This has also been shown in African-Americans, Pacific Islander and Maori people and Indigenous Canadians."

Dr Vanlint says the seasonal variation in vitamin D levels among the study group suggests that ultraviolet light - the best natural source of vitamin D - plays the major role in maintaining vitamin D levels.

"It is likely that time spent outdoors, particularly if it includes weight-bearing exercise, will have health benefits in addition to those associated with increased vitamin D production."

The study group comprised 40 women and 18 men from community-controlled health centres in Adelaide and Yalata in South 最新糖心Vlog.

Vitamin D plays an important role in helping the body to absorb calcium and maintain healthy bones, muscles and teeth. Vitamin D deficiency can increase a person's risk of bone and muscle pain, rickets (in children) and osteoporosis.

Recent studies have also suggested links between a lack of vitamin D and a wide range of conditions, including diabetes, heart disease, cancer, lung disease, mental health problems, skin disorders and some auto-immune diseases.

"If appropriate sunlight exposure is not sufficient or not possible, vitamin D is very safe to give as a supplement, and is not expensive," Dr Vanlint says.

"Given that vitamin D is very simple to provide as a supplement, it is possible that there could be significant health benefits for this section of our population."
