> Rates of deficiency were shown to be lower in summer (14%) and higher in winter (36%). There was little variation between the states and territories in summer, when deficiency levels were low across the country; ranging from 6% in Queensland to 19% in New South Wales. A divide was apparent in winter, with rates of vitamin D deficiency particularly high for those living in Victoria and ACT, where nearly one in every two people (49%) were vitamin D deficient in winter, compared with only 16% and 13% respectively in summer. In comparison, vitamin D deficiency remained relatively low in winter for those in Queensland and the Northern Territory.[10] Differences were also seen across each state or territory - vitamin D deficiency was more common among those living in major cities (27%) compared with those living in inner regional (16%), outer regional (13%) and remote areas (9%).[10]

(For non-Australians, Melbourne is the capital city of the state of Victoria.)
- hnick 6y agoAs someone in Sydney I was wondering about that connection. Cases are subsiding as we come into Spring, in Sydney and Melbourne both.
- h0l0cube 6y agoI've spent a lot of time in Melbourne, and it's winters are characterised by almost constant heavy cloud cover. That mixed with greater latitude makes natural vitamin synthesis by UV a real problem. There is also a large hole in the ozone around the southern hemisphere, so maybe that allows a little more UV through on less cloudy days.
