Follow-up studies of world war II and Korean conflict prisoners. III. Mortality to January 1, 1976.

Mortality through 1975 in US Army veterans released from prisoner-of-war camps following World War II (Europe, Pacific) and the Korean conflict and in several non-prisoner groups is compared using death rates and standard mortality ratios. The World War II Pacific and Korean conflict experience reveal increased risk of dying among former prisoners which, though diminishing with time, persist for 9 and 13 years, respectively. Mortality from tuberculosis and from trauma contributes to the increase among Pacific ex-prisoners, while for Korea the increase is limited to trauma. An excess of deaths due to cirrhosis of the liver in all three former prisoner groups appeared from about the 10th follow-up year. While the reported mortality experience for World War II spans 30 calendar years and for Korea 22 years, no evidence of increased aging among former prisoners of war is seen in mortality from the chronic and degenerative diseases.
