目的了解广安市初中生伤害行为发生状况及其影响因素,为开展有效干预措施提供依据。方法 2014年4月采用《中国青少年健康相关行为问卷》(初中版),以分层整群随机抽样方式抽取广安市4所初中初一至初三的1 103名初中生进行匿名自填式问卷调查,分析其伤害及相关行为发生率及影响因素。结果收回有效问卷1 069份,有效率为96.9%。调查对象中伤害发生率为20.7%,男生伤害发生率(22.4%)略高于女生(18.9%),初一学生中伤害发生率(24.7%)高于初二(18.5%)、初三(18.8%),但性别、年级差异均无统计学意义(P>0.05)。导致伤害的危险行为前6顺位依次为与他人打架(34.9%)、离家意念(26.7%)、心情郁闷(24.8%)、步行违章(20.4%)、自杀意念(19.2%)及到不安全地方游泳(13.8%),其中男生出现与他人打架和到不安全地方游泳的行为明显高于女生,而女生出现自杀意念的行为明显高于男生,性别间差异均有统计学意义(P<0.05);最常见的伤害发生原因为跌倒(19.4%)和被物体砸伤或碰伤(15.7%),并且男生更易因与他人打架而导致伤害发生,而女生则更易因自我伤害导致伤害发生,差异均有统计学意义(P<0.05);割刺伤(5.3%)和骨关节伤(5.2%)为最常见的伤害结果。非故意伤害行为中,骑车违章与非安全游泳行为更易导致伤害的发生,与没有此类行为的调查对象相比差异均有统计学意义(P<0.05);故意伤害行为中,暴力和校园暴力倾向、自杀或者离家行为及自杀或离家相关心理问题/障碍三方面均更易导致伤害的发生,与没有此类行为的调查对象相比差异均有统计学意义(P<0.05)。非条件logistic回归分析表明,离家出走(OR=2.452,95%CI:1.403~4.283,P=0.002)、被排斥孤立(OR=2.349,95%CI:1.145~4.821,P=0.020)、被恶意取笑(OR=2.173,95%CI:1.214~3.892,P=0.009)、与他人动手打架(OR=1.501,95%CI:1.092~2.062,P=0.012)、心情郁闷(OR=1.462,95%CI:1.039~2.058,P=0.029)等原因更容易导致伤害的发生。结论广安市初中生伤害发生率低于经济较发达的城市,离家出走、被排斥孤立、被恶意取笑、打架行为、心情郁闷等更容易导致伤害的发生。学校及家庭需加强对学生的心理应对方面的教育并做好防暴力教育,帮助其建立良好的家庭关系和朋友关系,预防并减少伤害的发生。 Objective To understand the occurrence and influential factors of injury among junior high school students in Guang’an and to provide basis for effective intervention. Methods A total of 1 103 middle school students from the first day to the third day of four junior high schools in Guang’an were investigated by using the “Chinese Youth Health-Related Behavior Questionnaire” (Junior High School Edition) in April 2014 to conduct anonymous self-administered questionnaire , Analyze the incidence of injuries and related behaviors and the influencing factors. Results A total of 1 069 valid questionnaires were retrieved with an effective rate of 96.9%. The incidence of injuries in the surveyed subjects was 20.7%, that of male students (22.4%) was slightly higher than that of girls (18.9%), that of first-year students (24.7%) was higher than that of primary two students (18.5% 18.8%), but there was no significant difference in gender and grade (P> 0.05). The 6th highest risk of injury was followed by fighting with others (34.9%), thoughts of leaving home (26.7%), depressed mood (24.8%), walking violation (20.4%), suicidal ideation (19.2% Swimming in safe places (13.8%), in which boys appeared to fight with others and swim in unsafe places was significantly higher than that of girls, while girls’ behavior of suicidal thoughts was significantly higher than that of boys, with significant differences between the sexes (P < 0.05). The most common causes of injuries were falls (19.4%) and bruises or bruises (15.7%), and boys were more likely to cause injuries as a result of fighting with others while girls were more susceptible to injuries due to self-harm , The differences were statistically significant (P <0.05); the most common injury results were incision injury (5.3%) and osteoarticular injury (5.2%). Among the unintentional injuries, the incidences of injuries that were more easily caused by biased cycling and unsafe swimming were significantly different from those who did not (P <0.05). Among the intentional injuries, violence and campus Violence, suicides or absences from home and suicide or psychological problems / disabilities related to leaving home were more easily caused by injury than those without such behavior (P <0.05). Non-conditional logistic regression analysis showed that the patients were isolated (OR = 2.452,95% CI: 1.403-4.283, P = 0.002) (OR = 1.173, 95% CI: 1.214-3.892, P = 0.009), and had a fight with others (OR = 1.501,95% CI: 1.092-2.06 2, P = 0.012) % CI: 1.039 ~ 2.058, P = 0.029) and other causes are more likely to cause injury. Conclusions The incidence of injury among junior high school students in Guang’an is lower than that in economically developed cities. It is easy to cause injuries if they run away from home and are excluded from exclusion. They are maliciously making fun of themselves, fighting behavior, feeling depressed and so on. Schools and families need to step up their education in coping with students’ psychological responses and educate them on violence prevention so as to help them establish good family relations and friendships and prevent and reduce injuries.
