Özet
Background: We tried to understand whether or not there are some seasonal differences in human mortality rates in the present study. Methods: The study was performed in the General Internal Medicine and Hematology Clinics between March 2007 and December 2010. All hospitalized cases in these units during the 45-month period were included into the study. The total number of deaths in each season were detected and compared. Results: There were 68 deaths during the period, with various causes. Although there were only three deaths in July, there were nine in October. In other words, the total number of deaths was the highest in autumn with 22 deaths (32.3% of all) in the 45-month period, totally. It was 13 (25.4%) in winter, 16 (23.5%) in spring, and 17 (25.0%) in the summer. Although there is obvious difference in the number of deaths between autumn and the other seasons, the difference was statistically nonsignificant probably due to the small number of death cases (p= 0.481). Conclusion: Although seasonal differences of human mortality rates were statistically nonsignificant, this was probably due to the small number of death cases of the present study; there may actually be a significant increase in autumn with unexplained reasons yet. Relative hormonal insufficiencies during the passage from a summer-like relaxed, to an autumn-like stressful season may be one of the causes. If so, it can be prevented by some hormonal replacement therapies, thus this theory should be searched with a higher number of cases in a more detailed approach.
