Contribution
of Poor Diet to SF Burden of Disease
The
Population Attributable Fraction (PAF) for mortality is the proportional
reduction in a specific cause of death that would have been expected
if the population had no exposure to a specific determinant.
It is calculated from the relative risk from exposure (RR) to the determinant
and the prevalence of exposure to the determinant in the population
(P), expressed as PAF = P(RR-1)/[P(RR-1) + 1]. Though
it has limitations, PAF is an important measure for public health planning.
A reasonable first
estimate of the PAF for all cause mortality associated with sexual behavior
is as follows:
