Long-term heart disease and stroke mortality among former American prisoners of war of World War II and the Korean Conflict: results of a 50-year follow-up.
For the first 30 years after repatriation, former American prisoners of war (POWs) of World War II and the Korean Conflict had lower death rates for heart disease and stroke than non-POW veteran controls and the U.S. population, but subsequent morbidity data suggested that this survival advantage may have disappeared. We used U.S. federal records to obtain death data through 1996 and used proportional hazards analysis to compare the mortality experience of POWs and controls. POWs aged 75 years and older showed a significantly higher risk of heart disease deaths than controls (hazard ratio = 1.25; 95% confidence interval, 1.01-1.56), and their stroke mortality was also increased, although not significantly (hazard ratio = 1.13; 95% confidence interval, 0.66-1.91). These results suggest that circulatory disease sequelae of serious, acute malnutrition and the stresses associated with imprisonment may not appear until after many decades.
