摘要:
探讨童年期同伴欺凌经历对青春期发育的影响,为开展预防青少年欺凌行为的健康教育提供参考.方法 于2014年9月采取整群抽样方法,选取安徽省马鞍山市3所小学三到四年级693名学生为调查对象,采用自编同伴欺凌问卷评价同伴欺凌经历,青春期发育量表(Pubertal Developmental Scale,PDS)评价儿童青春期发育情况.2015年9月再次对所有研究对象开展随访(654人),评估同伴欺凌与青春期发育的关联.根据儿童在基线与随访调查中2次报告的被同伴欺凌经历,将儿童分为无受欺凌组、持续组、新发组和消退组.结果 61.0% (399/654)的儿童在基线与随访中均无同伴欺凌经历,11.5%(75/654)儿童有持续受欺凌经历,14.8% (97/654)有随访期新发受欺凌经历,12.7% (83/654)随访期不再受欺凌.4组同伴欺凌经历青少年PDS得分与体质量指数(BMI)随访前后变化差值比较,持续欺凌组PDS得分明显高于无欺凌组、消退组和新发组;BMI变化值在同伴欺凌不同分组中差异无统计学意义(P>0.05).多元线性回归分析显示,相比于无欺凌组,持续受欺凌组男生PDS得分增高(β=0.249,95%CI=0.136~ 0.362);女生新发组和持续组PDS得分显著增高(β值分别为0.191,0.245,95%CI分别为0.076~0.305,0.123~ 0.367).结论 持续被同伴欺凌经历可能致男女童青春期发育加速.
Abstract:
Objective To ascertain possible effects of peer bullying victimization on follow-up pubertal development.Methods Children of grade 3 and grade 4 in 3 primary schools were selected through clustering sampling in Sept.2014 in Ma'anshan,Anhui province.All the participants were investigated with Bully/Victim Questionnaire and Multidimensional Peer Victimization Scale and Pubertal Development Scale (PDS) at baseline and 1-year after.Evaluate peer bullying by bullying questionnaire.Children were classified into four groups based on the baseline and follow-up peer bullying experience:without bullying victimization,consistent bullying victimization,newly bullying victimization and regressive bullying victimization group.Results About 61%(399/654) of children reported no experience of peer bullying,11.5%(75/654) reported consistent bullying victimization experience.During follow-up,14.8% who had no bullying experience at baseline reported bullying experience at follow-up while 12.7% who had bullying victimization at baseline reported no bullying victimization.Multiple linear regression showed that compared to the without bullying victimization group,PDS score increased significantly in boys with consistent bullying victimization group (β =0.249,95%CI=0.136-0.362),and in girls with newly and consistent bullying victimization groups (β were 0.191 and 0.245,respectively;95%CI was 0.076-0.305 and 0.123-0.367,respectively.).Conclusion Prolonged peer bullying victimization may lead to accelerated pubertal development among both girls and boys.
