Prevalence of comorbid conditions is stratified by sex, race/ethnicity, and obesity status. Incidence and relative risks of mortality for comorbid conditions are stratified by age, sex, race/ethnicity, and obesity status. The ranges of values across these stratifications are presented in this table.
For individuals with more than one of the comorbid conditions listed here, the model assigns only the maximum of the relative risks of mortality associated with those separate conditions (i.e. relative risks are not cumulative; an individual with a 1.5 relative risk of mortality due to coronary heart disease and a 3.5 relative risk of mortality due to cancer will experience a relative risk of mortality of 3.5).
The relative risk of mortality due to obesity ranged from 1.0 to 2.5.
While diabetes mellitus does not directly increase the risk of mortality in the model, individuals with diabetes mellitus are at increased risk for developing coronary heart disease, which can increase the risk of mortality.
