Misclassification and Confounding in the Air Force Health Study
Joel Michalek, PhD
Department of Epidemiology and Biostatistics, UTHSCSA
UT Health Science Center, 7703 Floyd Curl Dr
Medical School Bldg, Room 309L
Tuesday, April 7th
7 pm (6:30 pm refreshments)
Abstract: The Air Force Health Study was a 20-year epidemiological study of members of Operation
Ranch Hand, the Air Force unit that sprayed Agent Orange and other dioxin-contaminated herbicides in
Vietnam from 1962 to 1971. This talk summarizes decisions made during the study pertaining to
exposure metrics and adjustment. In retrospect, the most recent Air Force Health Study journal
publications suggest that confounders were missed and subjects were misclassified on exposure. This
talk details the path from protocol development to the final journal article in 2008, summarizing changes in
findings in cancer and diabetes to illustrate the time course of statistical adjustment during the 30 year
period from 1978 to 2008.
Parking: Visitor parking can be found in Lots 6 and 8.
