title: The effect of "parental loss" under 18 on developing "MDD" in adult age.
abstract: OBJECTIVE
  The aim of the study has been to search for the relations between Parental Loss in Childhood and Adolescence, and developing Major Depressive Disorder in Adulthood.
  
  
  METHODS
  The Study had chosen the "Retrospective Case Control" method carried out over 64 patients admitted in University Hospitals of Tehran, who were suffering from MDD (matching DSM-IV-TR criteria), as the "Case Group" and 68 non-depressive admitted patients as the "Control Group."
  
  
  RESULTS
  The study found that 19 out of 64 members of the "case group" (29.7%), and 7 out of 68 members of the "control group" (10.3%), has lost at least one parent under the age of 18. In other words, the prevalence of "parental loss" under 18 shows a meaningful increase in MDD among the "case group" in comparison with the "control group."
  
  
  CONCLUSIONS
  The study concludes that there is a noticeable statistical relationship between the variants of "parental loss during childhood and adolescence" and the "MDD during adult age."
