Summary

This video tutorial, presented by Thierry Ancelle, explains the concept and methods of rate standardization in epidemiology, focusing on mortality rates. It begins with a concrete example comparing mortality between two regions, A and B, where the crude mortality rate is higher in A, but age-specific rates are higher in B, illustrating the confounding effect of age structure. The video then introduces direct standardization, using a reference population (e.g., French population) to calculate standardized rates and the Comparative Mortality Figure (CMF). It demonstrates how to compute confidence intervals for the CMF and interpret results. Subsequently, it covers indirect standardization, calculating the Standardized Mortality Ratio (SMR) and its confidence interval. The presentation discusses the choice of reference population, limitations such as crossing of specific rates, and the importance of sufficient sample sizes. It concludes with applications to other indicators and factors, and references for further study.
