DESCRIPTION (provided by applicant): The objective of this methods proposal is to develop and apply new statistical methods to improve scientific inferences on the disease attribution associated with risk factors, such as obesity and tobacco smoking, for data collected from longitudinal cohort studies in chronic disease prevention research, specifically aiming to: (1) develop general statistical methods for time-varying attributable risk functions (ARF) to assess and compare prevention strategies; (2) develop statistical methods for a set of pairwise ARF's to assess and identify practically optimal prevention strategies; (3) develop statistical methods to evaluate the disease attribution in residual time; (4) develop statistical software and apply the developed methods to a large collection of cohort data from the Asia Cohort Consortium.
