Cancer Mortality, State Mean Elevations, And Other Selected Predictors, John Hart, Seunggeun Hyun
Dose-Response: An International Journal
This ecological inquiry compares cancer mortality rates in the U.S. to the predictor of natural background radiation (via land elevation means) along with eight other predictors thought to be associated with cancer mortality. Age-adjusted cancer mortality in 2006 was compared to the predictors of mean land elevation, percent of smokers, educational attainment, percent of population without health insurance, income, obesity, health perception, physical activity, and diet. Among the six predictors considered appropriate for multiple linear regression, three were found to be statistically significant; from strongest to weakest, these three were: smoking, land elevation, and educational attainment. The predictors of smoking …
Cancer Mortality In Six Lowest Versus Six Highest Elevation Jurisdictions In The U.S., John Hart
Cancer Mortality In Six Lowest Versus Six Highest Elevation Jurisdictions In The U.S., John Hart
Dose-Response: An International Journal
Low levels of background radiation exist around us continuously. These levels increase with increasing land elevation, allowing a comparison of low elevations to high elevations in regard to an outcome such as cancer death rates. The present study compares archived cancer mortality rates in six low versus six high elevation jurisdictions. The study also compares mortality rates for all causes, heart disease, and diabetes in low versus high elevation jurisdictions in an effort to see if other mortality outcomes are different in low versus high elevations. Statistically significant decreases in mortality, with very large effect sizes, were observed in high …
Mean Cancer Mortality Rates In Low Versus High Elevation Counties In Texas, John Hart
Mean Cancer Mortality Rates In Low Versus High Elevation Counties In Texas, John Hart
Dose-Response: An International Journal
There is controversy as to whether low levels of radiation (i.e., < 5 rem) pose a health risk. This brief inquiry compares archived cancer mortality data in counties having relatively low (0-250 feet above sea level), medium (500-1000 feet above sea level), and high (3000+ feet above sea level) elevations also having corresponding greater natural back- ground levels of radiation respectively. Cancer mortality was found to be lowest in the high elevation counties (mean = 58.2) followed by low elevation counties (67.5) and then medium elevation counties (70.4). Statistically significant differences were found between low –high elevations (p = 0.003), and medium – high elevations (p = 0.010), but not between low and medium elevations (p = 0.5). More rigorous research, with an accounting of con- founding variables, is indicated.
