Objective To observe the effects of childhood trauma on patients with different types of depression,and ex-plore whether childhood trauma affects the somatic symptoms of depressed patients.Methods A total of 121 depressed patients who attended outpatient clinics and were hospitalized in the psychiatry department of Chaohu Hospital Affiliated with Anhui Medical University and the Psychiatry Department of the Second Affiliated Hospital of Anhui Medical Univer-sity from October 2022 to December 2023 were selected to assess the short version of the childhood trauma questionnaire short form(CTQ-SF)childhood trauma inventory,the somatization subscale of the SCL90 symptom self-assessment checklist,and the 17-item Hamilton depression inventory.Results Depressed patients with somatization symptoms had higher CTQ-SF total scores than depressed patients without somatization symptoms[46.50(39.25,58.25)vs.39.50(34.00,50.00),Z=-2.662,P<0.01];depressed patients with somatization symptoms had higher levels of somatic neglect[8.00(7.00,10.00)vs.7.00(5.00,9.00),Z=-2.683,P<0.01]and emotional abuse[9.50(7.00,15.00)vs.8.00(6.00,11.50),Z=-2.317,P<0.05]scores.The severity of childhood trauma was positively associ-ated with the severity of somatization symptoms in depressed patients(P<0.01),and this association persisted after con-trolling for the severity of depressive symptoms(P<0.01);somatization symptoms were associated with all childhood traumas except sexual abuse(P<0.01);and after controlling for the severity of depressive symptoms,somatization symp-toms remained associated with somatic neglect(P<0.01)and emotional abuse(P<0.05)were positively associated.Conclusion Depressed patients with somatization symptoms experienced more severe childhood trauma,and a history of childhood trauma,including physical neglect and emotional abuse,had an impact on somatization symptoms in depressed patients.
