| 目的了解大学生故意自伤行为和自杀行为的发生情况，并分析其相关性。方法方法整群选取某医科大学4063名一、二年级在校生为研究对象，采用#检验比较不同性别大学生故意自伤行为、自杀行为检出率差异，建立多因素logistic回归模型拟合多种研究变量对故意自伤行为一自杀行为的影响。结果4063名大学生最近1年故意自伤行为检出率为13。4％，其中单次自伤检出率为3。7％，多次检出率为9。6％，男生高于女生；最近1年自杀意念、自杀计划、自杀未遂和自杀行为的检出率分别为4。 5％、1。4％、O6％和4。 9％，性别问差异无统计学意义(P>O。05)。采用多元logistic回归分析，以有自伤无自杀组为参考，有自伤有自杀组表现为积极应对程度低(OR=O。5，95％CI：0。3～O。8)、伙伴个数相对较少(3，5个vs。≤2个：OR=O。6。95％C1：0。3—0。9；>／6个％。≤2个：OR=O。4，95％CI：0。2。O。8)；消极应对(OR-----2。 1，95％6'／：1。2～3。7)、抑郁症状(OR=2。 9，95％C／：1。6—5。 2)、焦虑症状(OR=2。 2，95％C／：l。2—3。8)、睡眠问题(OR----1。7，95％Cl：1。1—2。 8)、自评体型偏胖(偏胖m。正常：OR=2。 0，95％CI：1。1—3。6)较为常见。logistic回归分析发现，大学生故意自伤行为者中自杀行为的发生风险显著增加(OR=4。 7，95％CI：3。5—6。4)，而抑郁、应对方式、自评体型等社会心理因素会减弱两者的关联程度(OR=3|3，95％a：2。 4—4。 5)。自杀行为发生的风险随自伤次数的增加而增加(OR-----3。1—10。0)，社会心理因素也会减弱两者的关联(OR=2。 4—5。 9)。结论自伤行为虽然不是个体自杀行为发生的信号，但有必要在自伤者中开展自杀行为发生可能性的评估。 |

| Objective To describe the prevalence ofdeliberate self-harm(DSH)and suicidalbehaviors(SIB)as well as the relationship between them in a college student population.Methods A total of 4063 medical students were selected under the cluster sampling method in Anhui province.Data were analyzed by Pearson Chi—square and logistic regression.Results A total of4063(13.4％)students reported that they had deliberately harmed themselves during the past 12 months.The acts of DSH with 1 and more than or equal to2 times occurence ac+M4counted for3.7％and9.6％among all the respondents.The act of DSH was significantly higher among boys than that among girls.Rates of suicide ideation.suicide plan,attempted suicide and SIB in the last 4. 5％,1.4％.0.6 and4. 9%,respectively.However no statistically significant dilyerence was found in different sex.Students in the DSH groupnlat with SIB were found to have lower positive coping levels(OR=O.5,95％C／：0.3—0.8).getting less support from frithds(3-5 vs.1ess than or equal to 2：OR=O.6,95％c,：0.3—0.9；more than or equal to 6∞.1ess than or equal to 2：OR=O.4,95％C,：0.2-0.8).with highor negative coping levels(OR=2,1,95％CI：1.2—3.7),having more serious depressive symptoms(OR=2. 9,95％c,：1.6—5. 2)and anxiety symptoms(OR=2. 2. 95％CI：1.2—3.8).having more serious sleeping problems(OR=1.7. 95％C,：1.1—2. 8)and perceived fat(fat.moderate：OR=2. 0,95％CI：1.1—3.6)than the DSH group without SIB.The rates of SIB in students with DSH behavior were significantly higher than those in students without those behaviors(OR---4. 7,95％C／：3.5—6.4).Psyehosocial variables could attenuate the relationship between the DSH status and suicidal events (OR=3.3.95％CI：2. 4—4. 5).The DSH frequency exhibited a curvilinear relationship to SIB(OR=3.1一lO.0)and psychosocial variables also attenuated this relationship(OR=2. 4—5. 9).ConclusionIt was well known that SIB was not a suicidal gesture but our findings suggested that the presence of DSH might trigger the suicidal attempts. |
