Vitamin D testing has increased dramatically in New South Wales, Australia in recent years, new study says

A new study published in Singapore Medical Journal has found that vitamin D testing in New South Wales, Australia has increased 8-fold between 2001 and 2010. However, the results show that vitamin D levels are still low despite this increase in testing.

Globally, vitamin D testing is increasing. For example, in San Francisco, vitamin D testing increased 20-fold between 2006 and 2009. Ontario, Canada saw similar results with a 25-fold increase in testing between 2004 and 2010.

Recently, researchers conducted a study to determine if these same trends were occurring in New South Wales, Australia.

To do so, they analyzed patient records between 2001 and 2010 to determine how many people were getting their vitamin D levels tested and what the average vitamin D levels were in these years. Overall, the researchers collected 41,177 records over the study period.

They found that the number of vitamin D tests performed increased from 1,265 in 2001 to 10,499 in 2010.

“These increases suggest a greater awareness within the medical community regarding the importance of vitamin D status to effective healthcare,” the researchers stated.

The researchers also found that average vitamin D levels increased over the study period with the highest levels being reported in 2010.

Despite the overall increase in vitamin D tests and vitamin D levels, 33% of men and 40% of women were vitamin D deficient, with levels less than 20 ng/ml. The average vitamin D levels were 23.24 ng/ml and 20.44 ng/ml, respectively.

The researchers call for further research on vitamin D testing and vitamin D levels in at-risk subpopulations to help improve the effectiveness and delivery of healthcare services.

3 Responses to Vitamin D testing has increased dramatically in New South Wales, Australia in recent years, new study says

  1. Vitamin D levels have also been increasing.
    Recently 20X more vitamin D was sold in all of Australia
    Also there was a 30% decrease in osteoporosis visits – which may be associated.
    The study referred to on this page contains a chart which shows a INCREASE in vitamin D over 5 years.

    A little story about Australia and Vitamin D:
    For decades Australians had been told that sunshine was deadly.
    They avoided the sun, and some even used sunscreen 24 hours a day, during all seasons.
    Then they noticed a big increase in a great many diseases.
    The public thought that these increases might be due to low vitamin D from lack of sun.
    The doctors said no, could not be, and the government would not even allow selling capsules containing more than 1000 IU
    The public asked for vitamin D tests (about a 100X increase in 11 years)
    The government then refused to pay for any more (unnecessary) vitamin D tests.
    That did not stop the public – they took matter into their own hands.
    Australia is the only country which has shown a recent INCREASE in vitamin D levels

    Uh, excuse me, but uh, any and every fool and non-fool can figure out that we have been lied to, on purpose, by the medico-pharmaceutical establishment about sunshine, Vitamin D, cancer, tooth decay, junk food — just name it.

    Legislators cannot even protect us from sugary soft drinks. Executives are corporate mouth-pieces. Start suing doctors, corporations, school systems and maybe, maybe, a lone Solomon will emerge from the judicial branch to save America from disintegration-by-sickliness.

    I am afraid that 65 years of TV commercials have done America in. Today’ school kids have great-grandparents who were indoctrinated as children by Madison Avenue Ads on TV. My own mother 94, after 65 years of commercial TV, although too poor to buy anything advertised on TV, nonetheless will argue with me that if a TV dude in white recommends 400 IU’s of Vitamin D — he is right.
