Multiple causes of death and their contribution to population attributable fractions for smoking

This project will estimate the smoking attributable fractions of death, incorporating multiple causes of death into relative risk estimation. Cause of death will be ascribed using two different methods - the UC only and a multiple cause weighting strategy.

About

The project will use large scale linked data to investigate multiple causes of death and their contribution to population attributable fractions. The multiple cause weighting strategy conceptualizes mortality as being the result of a mixture of disease processes, thus acknowledging that multiple diseases may act together to cause death, rather than relying on one underlying cause of death.

The project will estimate the smoking attributable fractions of death, incorporating multiple causes of death into relative risk estimation. Cause of death will be ascribed using two different methods - the UC only and a multiple cause weighting (WT) strategy, ascribing 50% weight to the UC and apportioning the remaining 50% equally across the contributing causes reported in Part II of the death certificate.
Methods for redistribution of ill-defined and non-specific contributing causes will also be explored.
