OBJECTIVE To study the relationship between various forms of childhood abuse and suicidal behaviors among middle school students.
METHODS A total of 14 221 cases were retained from an epidemiological study,involving students from junior and senior middle schools in Guangzhou,Xinxiang,Shenyang and Chongqing.Information related to the demographic characteristics,types,number,timing and perpetrators of exposure to childhood abuse and suicidal behaviors was obtained.Logistic regression was used to analyze the relationships of each form of childhood abuse and suicidal behaviors.
RESULTS Number of cases (rates) of childhood abuse,physical abuse,emotional abuse,sexual abuse,suicidal ideation,suicidal planning and suicidal attempts among middle school students appeared as 7 246 (51.0％),5 824 (41.0％),5 409 (38.0％),1 039 (7.3％),2 042 (14.4％),1 174 (8.3％) and 548 (3.9％),respectively.Boys reported more physical abuse than girls,while girls reported more emotional abuse and suicide ideation than boys (P＜0.01).However,no gender differences were found in cases as sexual abuse,suicide planning or attempted suicide (P＞0.01).After controlling for confounding variables,experiences on childhood abuse were significantly associated with suicidal ideation (OR=2.03,95％CI:1.72-2.40) and suicidal planning (OR=1.93,95％CI:1.57-2.37) among boys but significantly associated with suicidal ideation (OR=2.45,95％CI:2.12-2.82),suicidal planning (OR=2.46,95％CI:2.02-3.00) and attempted suicide (OR=2.12,95％CI:1.61-2.78) among girls.
RESULTS from multivariable logistic regression analysis showed that each type of childhood abuse,occurring at any time within the first 16 years of life,especially with continuous exposure,was significantly associated with suicidal behaviors.A significant graded-relationship was found between number of abusive childhood experiences and suicidal behaviors.Students that had been maltreated by parents or others were at high risk of engaging in suicidal behaviors.
CONCLUSION The findings suggest that the experience of any form of childhood abuse should be considered a risk factor for suicidal behaviors among the middle school students.
