A Study On The Epidemiological Characteristics And Influence Factors Of Non-suicidal Self-injury Among Medical Students In A University In Nanchang

Objective: This study aimed to investigate the detection feature and influence factors of non-suicidal self-injury among medical students.Methods: In Nanchang University school of medicine in school undergraduate(grade2-3)as the research object,using self-designed questionnaire,and through the entries of Ottawa self-injury scale of self-injury,Multidimensional sub-health questionnaire of adolescents(MSQA),Egna minnen av barndoms uppfostran-own memories of parental rearing practices in childhood(EMBU)and Adolescent life events scale(ASLEC)collect the necessary information.Data analysis was performed using SPSS 20.0.Results:1.Among the 1826 medical students,187(10.2%)were diagnosed as probable NSSI-positive individual.The detection rate of male(11.2%)was higher than that of female(9.5%),but the difference was not statistically significant(?~2=1.382,P= 0.240).2.There were significant differences in the positive rate of NSSI among medical students in terms of "whether they suffered from childhood abuse","genetic relationship with parents living together","family economic status","self-rated health status" and other factor(P<0.05);family location(town/village),"whether only child" is not associated with NSSI(P>0.05).3.In the NSSI implementation,the use of more "hard bite yourself"(51.3%),"pick or scratching themselves"(50.8%),"hard to pull their hair"(35.8%).Which "swallow or drink can not eat things" more male than female,the difference was statistically significant(?~2=5.703,P=0.017).The proportion of NSSI with1,2,3 and above was 49.7%,25.7%,24.6%,the difference was not statistically significant(?~2=1.602,P=0.449);the last NSSI reason,due to family problems occurred NSSI women more than men,the difference was statistically significant(?~2=8.946,P=0.003).4.In the parental rearing style,the average score(15.78+4.51)of NSSI was higher than that of non-NSSI(13.8+3.121),the difference was statistically significant(P=0.0001).Parental rearing,excessive intervention[OR=1.11,95%CI=(1.004~ 1.226)]and denial of denial[OR=1.292,95%CI=(1.1364~1.469)]is an independent risk factor for NSSI.5.In multidimensional sub-health questionnaire of adolescents,the average score(57.02+23.98)of NSSI was higher than that of non-NSSI(43.25+16.95),the difference was statistically significant(P=0.001).Emotional problem factor[OR= 1.064,95%CI=(1.049~1.079)] is an independent risk factor for NSSI.6.In adolescent life events scale,the average score(55.68+20.148)of NSSI was higher than that of non-NSSI(42.91+14.59),the difference was statistically significant(P=0.001).Learning and stressing factors[OR=1.104,95%CI=(1.058~ 1.151)],is an independent risk factor for NSSI.7.NSSI was statistically correlated with suicidal ideation,suicidal plan and suicidal attempt,and their OR values were 5.403[95%CI(3.475,8.400)]?9.067 [95%CI(3.145,26.141)] and 4.437[95%CI(1.101,17.892)].8.Multivariate logistic regression analysis shows that "even if it is a small fault,the parents also punish me," "parents often told me similar to this kind of words 'This is what we do for you all day to get the repayment?'","Often Feel nervous "," often fearlessly for no reason "," expected selection failed "," parents beat " and other independent risk factors for the NSSI.Conclusion:1.The detection rate of NSSI was 10.2%,which was lower than that of NSSI among college students at home and abroad.The detection rate of NSSI was similar to that of NSSI students at home and abroad.2."Whether they suffered from childhood abuse","genetic relationship with parents living together","family economic status","self-rated health status" is associated with NSSI;gender,family location(town / village),"whether only child" has nothing to do with NSSI.3.In the NSSI implementation,the use of more "hard bite yourself","pick or scratching themselves","hard to pull their hair".Which "swallow or drink can not eat things" more male than female,due to family problems occurred NSSI women more than men.4.The occurrence of NSSI is related to factors such as parental rearing patterns,multidimensional sub-health of adolescents,adolescent life events,suicidal ideation,suicide plans and attempted suicide attempts.5.Medical students NSSI prevention and control,may need the family,school,social joint efforts.
