Cumulative exposures depend on both the intensity and duration of exposure and thus require special methodological consideration. This talk will demonstrate modeling techniques applied to an example exposure – gestational weight gain (GWG) – within a longitudinal data source utilizing EMR data. GWG is cumulative during pregnancy, and pregnancy length determines how long pregnant people can gain weight: those with shorter pregnancies have a “truncated” exposure window compared to those with longer pregnancies. We cannot directly compare these two groups using traditional measurement methods and must utilize methods that account for this truncation. The talk will conclude by discussing possible applications to other exposures.
