Title: Solar Activity and hospitalizations for depressive episodes in Chile


Introduction: This study presents the relationship between solar activity and the incidence of hospitalizations for depressive disorders found in the register of the Ministry of Health of Chile, where all the hospital discharges from 2001 to 2008 are kept. Solar activity is represented by the Wolf number, with the formula R = K (10g+f), where g refers to the group of sunspots and f is the total number of sunspots.
Method: The databases of the Ministry of Health show all the hospital discharges, whether for psychiatric causes or other diagnoses, including data from public as well as private hospitals. For the sample analysis, the cases diagnosed as depressive disorders according to the classification CIE 10, ranging from F320 to F339, both included, were selected. We analyzed the correlation between annual incidence of hospitalizations for depression and the average of the Wolf number for that particular year between the period spanning from 2001 to 2008, both included, which corresponds to approximately half of a solar cycle of 16 years.
