Estimating “actual causes of death” Start with data on deaths by disease category (heart disease, cancer, etc.) Calculate “attributable fractions” (AFs) for Example: > 90% of all lung cancer deaths attributable to smoking More-or-less a “black box,” depending on science behind the AFs
Ingredients for the estimates of AF • Risk factor prevalence (P 0 , P 1 , …) Self-reported behaviors (smoking, alcohol, drugs, …) • Relative risk ratios (RR 1 , RR 2 , …) Vast, complicated, controversial body of research Dispute over RR for obesity, overweight Mokdad et al. cite 97 studies Some cited studies are literature reviews, meta- analyses of other studies Article has 6 pages of text
