The following Table revises Table 3, which appeared on page 153 of our recent report.1 Table presented here incorporates two sets of changes: 1) We corrected an error in the rural-urban category that had affected the results for that variable and the model. 2) In a letter to the editor, Hendryx and Ahern challenged our findings and they also posted their dataset for these variables.2 As discussed in our reply to their letter, we determined that there were differences between our datasets for seven other variables, of which four (adjusted mortality rate; high school education rate; college education rate; and coal mining (yes/no)) were significantly different.3 We have not determined which of the datasets, ours or theirs, is “more correct” for six of those variables, but their coal mining variable is clearly incorrect. To avoid further disputes, the following Table incorporates the WVU data for adjusted mortality, high school education and college education rates.

The analytical results are quantitatively different from our original report, but qualitatively unchanged. Coal mining remains not significantly associated with mortality. We regret any inconvenience caused by our error in assigning the Rural-Urban category variables.

Abstract

Objective: To determine the predictive value of coal mining and other risk factors for explaining disproportionately high mortality rates across Appalachia.

Method: Mortality and covariate data were obtained from publicly available databases for 2000 to 2004. Analysis employed ordinary least square multiple linear regression with age-adjusted mortality as the dependent variable.

Results: Age-adjusted all-cause mortality was independently related to Poverty Rate, Median Household Income, Percent High School Graduates, Rural–Urban Location, Obesity, Sex, and Race/Ethnicity, but not Unemployment Rate, Percent Uninsured, Percent College Graduates, Physician Supply, Smoking, Diabetes, or Coal Mining.

Conclusions: Coal mining is not per se an independent risk factor for increased mortality in Appalachia. Nevertheless, our results underscore the substantial economic and cultural disadvantages that adversely impact health in Appalachia, especially in the coal-mining areas of Central Appalachia.
