The SunSmart UV Alert pamphlet included information on UV radiation, the UV index, and on sun protection [ 20].
Low annualized UV index at the HOR did not increase the likelihood of developing stress fractures.
U.S. residents can obtain UV Index forecasts through the EPA's SunWise website (http://epa.gov/sunwise/uvindex.html).html
The incidence rates for stress fractures were 26.0, 31.3 and 31.1 cases/1,000 person years for low, moderate and high UV index regions, respectively, with those in the low UV index group showing a lower risk compared to the high UV index group (OR low UV/high UV = 0.83, 95%CI = 0.80-0.87; p < 0.01).
The UV index is a 1 10 scale, with 10 being the highest UV radiation level.
The daily "Issued UV Index" is used throughout this paper and incorporates cloud information (as opposed to "clear sky UV index").
Then, HOR UV index was stratified by race/ethnicity and logistic regression was used to assess the relationship of HOR UV index levels for each separate race/ethnicity.
In this subgroup analysis, the stress fracture injury risk of men in the low annualized UV index was similar to the risk in men in the high UV index group (OR low UV/high UV = 0.95, 95%CI = 0.89-1.03; p = 0.20) and females in the low annualized UV index had a modestly lower injury risk compared to women in the high UV index group (OR low UV/high UV = 0.90, 95%CI = 0.83-0.97; p < 0.01).
Our research continues to provide the scientific basis for services to Canadians, including the UV index".
At least 25 countries' use some form of UV index to advise the public.
(Spending time in the sun on days with a high UV index can lead to skin damage from the sun more quickly than on days with a lower UV index).
