Abstract:
Objective:To summarize the clinical characteristics of suicidal behavior in children and provide a reference for further developing strategies for preventing childhood suicide.Methods:The medical records of children hospitalized in the pediatric intensive care unit（PICU）at Beijing Children's Hospital for suicidal behavior in the electronic medical record system from January 1,2018,to December 31,2022 were retrospectively selected.Clinical data of children with suicidal behavior were collected.Results:A total of 3 249 patients were admitted to the PICU,including 62 suicide patients.There were 20(32.3%) males,and 42(67.7%) females,with a male-to-female ratio of 1:2.1.The average age was (13.1 ± 1.5) years old,with a minimum age of 7.9 years and a maximum age of 15.7 years.There were 17 (27.4%) children with previously diagnosed mental illnesses.Notably 58.1% children had triggering factors for suicidal behavior.Analysis of suicide methods,53(85.5%) cases were intentional drug ingestion,six(9.7%) cases were jumping from height,and three(4.8%) cases were hanging.Additionally 26.4% cases of poisoning were male,while 66.7% of cases of jumping from height and hanging were male.There was a statistical difference in suicide methods between genders (χ 2=5.704, P=0.025).The poisoning ingestions were classified as 20(37.7%) cases of toxins; 14(26.4%) cases of antidepressants; 10(18.9%) cases of over-the-counter drugs; five(9.4%) cases of other prescription drugs; three(5.7%) cases of sedative drugs; one(1.9%) case of daily chemical.Sources of ingestions: 18(34.0%) cases were purchased personally (pharmacies or online shopping); 16(30.2%) cases were storing medicines at home; 13(24.5%) cases were daily taking antidepressants.Compared with non-poisoning patients,poisoning patients had a significantly shorter PICU duration (Z=-2.884, P=0.004).The total mortality rate of children admitted to PICU due to suicide was 16.1%(10/62).There was a statistical difference in the mortality rate among different suicide methods (χ 2=7.883, P=0.019). Conclusion:School aged children and boys are more likely to choose impulsive and more harmful suicide behaviors such as jumping from heights and hanging,and adolescent girls are more likely to choose intentional poisoning as their suicide method.Attention should be paid to the suicide risk of different age and gender groups.Intentional drug ingestion is the main method of suicide in children.Herbicide poisoning and antidepressant drug poisoning are the leading causes of suicide death.The death risk of suicidal behavior in children may be reduced by controlling the way of getting pesticides (especially herbicides) and obtaining maximum doses of antidepressants.
