Medical Surveillance Monthly Report (MSMR). Volume 3, Number 1, January 1997
Abstract
During calendar years 1995 and 1996, there were 293 cold weather injuries (CWI) among active duty soldiers reported to the Armys Medical Surveillance System (MSS). This report summarizes demographic characteristics of cases and compares the experience of 1995 to 1996. To determine the significance of relative excesses or deficits of CWI in various demographic subgroups, we compared reported (observed) numbers of cases to expected cases. Expected numbers of cases were calculated based on the hypothesis that CWI would distribute among demographic subgroups of the Army in proportion to their representation in the general population of the Army. Thus, expected numbers of cases for various subgroups were calculated by multiplying the proportional representation of each subgroup in the Army by the total number of reported CWI cases. The statistical significance of variations between observed and expected numbers were then assessed based on the Poisson distribution (statistical significance was defined as p<.05).
