Childhood maltreatment with school bullying behaviors in Chinese adolescents: A cross-sectional study.

Although childhood maltreatment and school bullying are common among Chinese adolescents, their possible connection remains severely under-discussed in this population. This study primarily aims to explore the association between childhood maltreatment experience and school bullying behaviors in a large sample of Chinese teenagers. A school-based sampling survey was implemented with 2579 adolescents in southwest China. Self-administered questionnaire was used to collect relevant information form the participants. Binary Logistic regression models were adopted to estimate the crude and adjusted associations between childhood maltreatment experience and school bullying involvement in general, as well as between different types of child maltreatment and school bullying. Multivariate Logistic regression models revealed that, for adolescents who had experienced any type of childhood maltreatment, their risk of implicating into school bullying significantly increased (OR=1.75, 95% CI: 1.41-2.16). Further analysis revealed that, for all types of childhood maltreatment and school bullying, only child abuse showed prominent association with bullying victimization: adolescents who reported a history of sexual abuse and emotional abuse were found 4.31 (95% CI: 2.79-6.68) and 2.11 (95% CI: 1.32-3.39) folds of odds for bullying victimization. However, the dose-response association was not apparent between the severity of child abuse and bullying victimization based on subgroup analysis of abused participants. Childhood maltreatment, especially sexual abuse and emotional abuse, were significantly associated with increased risk of school bullying victimization among Chinese adolescents. Targeted intervention measures should be designed and implemented to protect the abused adolescents from being bullied at school.

Childhood maltreatment and parenting style associated school bullying in Chinese children and adolescents: An analytical epidemiology evidence.

The independent associations among childhood maltreatment (CM), parenting style, and school bullying in children and adolescents have not been adequately discussed. Epidemiological evidence of higher quality is still scarce. We intend to investigate this topic by using a case-control study design in a large sample of Chinese children and adolescents. Study participants were chosen from the Mental Health Survey for Children and Adolescents in Yunnan (MHSCAY), a mega ongoing cross-sectional study. The combined database from four study sites was used. The population-based case-control study was individually matched by study site, age, sex, race, left-behind status, whether a single child, and whether a boarding student. Cases were observed to have a significantly higher prevalence of CM, higher scores for parental rejection and over-protection, and lower scores for parental emotional warmth. Multiple conditional logistic regression revealed that CM, especially emotional abuse (EA) and sexual abuse (SA), were associated with a prominently increased risk of school bullying involvement, with adjusted odds ratio (OR) of 2.28 (95 % CI: 2.03, 2.57) and 1.90 (95 % CI: 1.67, 2.17). Subsequent analysis further corroborated the robustness of EA-bullying and SA-bullying associations. Although parenting style generally showed a weaker association with school bullying, a higher level of parental rejection was related to an increased risk of bullying victimization. Chinese children and adolescents who are victims of EA or SA, or experienced a higher level of parental rejection, are more vulnerable to school bullying. Targeted interventions should be designed and implemented.

Associations between childhood maltreatment and non-medical use of prescription drugs among Chinese adolescents.

To test, among Chinese adolescents: (1) whether childhood maltreatment is associated with non-medical use of prescription drugs (NMUPD) and (2) whether there are interaction effects of childhood maltreatment and depressive symptoms on NMUPD. A secondary analysis of the cross-sectional data collected from 7th- and 12th-graders who were sampled using a multi-stage, stratified-cluster, random-sampling method in the 2015 School-based Chinese Adolescents Health Survey (SCAHS). Surveys conducted in high schools in six cities of China in 2015. There were 24 457 students who were invited to participate and 23 039 students' questionnaires were completed and qualified for our survey. The outcomes comprised self-report of NMUPD (prior 30 days); a history of childhood maltreatment was our main predictor. Other covariates included depressive symptoms, smoking, drinking and demographics. Data were analysed using multi-level regression modelling. Our final multivariable logistic regression models demonstrated that after adjusting for other variables, physical abuse was associated positively with non-medical use of opioids [adjusted odds ratio (AOR) = 1.13, 95% confidence interval (CI) = 1.10-1.22], sedatives (AOR = 1.11, 95% CI = 1.10-1.21) and any prescription drugs (AOR = 1.13, 95% CI = 1.09-1.20); emotional abuse, sexual abuse and emotional neglect were also associated with an increased risk of opioids, sedatives and any prescription drugs misuse; students who reported that they had experienced childhood physical neglect were more likely to be involved in the non-medical use of sedatives (AOR = 1.08, 95% CI = 1.04-1.12) and any prescription drugs (AOR = 1.06, 95% CI = 1.03-1.10). Additionally, there was no evidence of interaction effects on NMUPD between depressive symptoms and each of physical abuse, emotional abuse, sexual abuse, physical neglect and emotional neglect, respectively. Maltreatment while a child is associated with an increased risk of non-medical use of prescription drugs (NMUPD) among Chinese adolescents. The interactions of maltreatment while a child and depressive symptoms do not appear to be associated significantly with NMUPD among Chinese adolescents.

Examining Childhood Maltreatment and School Bullying Among Adolescents: A Cross-Sectional Study From Anhui Province in China.

Although a body of research has established the relationship between childhood maltreatment and bullying in Western culture backgrounds, few studies have examined the association between childhood maltreatment experiences and bullying in China. Moreover, to date, the relationship between multiple types of childhood maltreatment and cyber bullying is poorly understood. This study examined the association between multiple types of childhood maltreatment (physical abuse, emotional abuse, sexual abuse, physical neglect, and emotional neglect) and multiple forms of school bullying (physical, verbal, relational, and cyber). A cross-sectional study using three-stage random cluster-sampling approach was conducted in Tongling, Chuzhou, and Fuyang, in Anhui Province. Self-reported questionnaires were completed by 5,726 middle school students to assess their school bullying involvement and childhood maltreatment experiences. A multivariable logistic regression analysis was used to explore the relationship between each single type of childhood maltreatment and each single form of school bullying. Each type of childhood maltreatment was associated with increased risk for involvement in each form of bullying as bullies, victims, and bully-victims. Specifically, both childhood physical neglect and emotional neglect were associated with increased risk for involvement in each form of school bullying. Each type of childhood maltreatment was associated with involvement in cyber bullying. Students who experienced multiple types of childhood maltreatment seem to report more forms of school bullying. Furthermore, multiple forms of school bullying caused the co-occurrence of several forms of school bullying. Our results indicated a significant association between school bullying and childhood maltreatment among adolescents. Interventions to reduce school bullying encompassing prevention toward childhood maltreatment might get better results in China.
