The Promise of Prevention: The Effects of Four Preventable Risk Factors on National Life Expectancy and Life Expectancy Disparities by Race and County in the United States
Why the study?
Does the reduction of smoking, high blood pressure, elevated blood glucose, and adiposity to optimal levels improve national life expectancy and reduce disparities in the US population?
Population
US population in 2005, categorized into eight subgroups based on race, location, and socioeconomic…
Comparison
Modeled reduction of four modifiable risk… vs Current exposure to the four risk factors.

Implication
Reducing these risk factors to optimal levels could narrow US life expectancy disparities by 18-21%; confirms their major role in national inequities.
Structured PICO
Does the reduction of smoking, high blood pressure, elevated blood glucose, and adiposity to optimal levels improve national life expectancy and reduce disparities in the US population?
P
Population
US population in 2005, categorized into eight subgroups ('Eight Americas') based on race, location, and socioeconomic characteristics of county of residence.
I
Intervention
Modeled reduction of four modifiable risk factors (smoking, high blood pressure, elevated blood glucose, and adiposity) to optimal levels.
C
Comparator
Current exposure to the four risk factors.
O
Outcome
National life expectancy and disparities in life expectancy and disease-specific mortality.hard clinical
Disparities in smoking, blood pressure, blood glucose, and adiposity explain a significant proportion of life expectancy and cardiovascular mortality disparities in the US.
