In a matched controlled study 72 Canadian patients with a major depressive episode were compared with non-depressed and never depressed orthopedic patients. Significantly more of the depressives had parental loss before 17 years of age, a poor marriage before the onset of depression and a family history of depression.
在一项配对对照研究中,72名患有重度抑郁发作的加拿大患者与非抑郁且从未患过抑郁症的骨科患者进行了比较。抑郁患者在17岁之前经历父母丧亡、在抑郁发作前婚姻不幸以及有抑郁症家族史的情况明显更多。
