Public Health Service, Washington, D.C.: U.S. Government Printing Office. Death rates due to diabetes mellitus are higher for the U.S. than for Utah when crude rates are compared, but higher for Utah when age-adjusted rates are compared (see Table 20, and Figure 18 for age-adjusted comparisons). This reversal is due to Utah's younger population in comparison with the national average; an older population tends to die from such chronic disease conditions at an increased rate. Age-adjusted rates compare similar age groups to one another, eliminating the possibility of a disproportionately younger population's skewing the rate calculations. Crude rates were included for diabetes mellitus because they help illustrate the importance of using age-adjusted data for comparisons whenever possible. Often rates are reported in the media without mentioning whether they are adjusted to account for potential confounding variables such as age. Differences between diabetes mellitus comparisons for Utah and the nation for both crude and age-adjusted death rates clearly illustrate the importance of using age-adjusted rates. > A Utah:U.S. comparison shows Utah deaths to be about one-tenth higher on average than U.S. deaths. Utah's death rates from diabetes mellitus dropped from 1970 to 1983, but then increased. 20 HEALTH STATUS |
