School bullying has negative impacts on the overall health of children and adolescents, but the association between bullying and oral health-related quality of life (OHRQoL) is still unclear.
In this study, a two-wave prospective design was used to collect data in Yunnan Province, southwest China. A total of 5,346 children and adolescents aged 10-17 years were included in the study through two-stage randomized cluster sampling. Univariate and multivariate logistic regression models were employed to assess the sequential associations between baseline bullying and the subsequent OHRQoL. Stratified analyses were further performed to evaluate the effect modification by important demographic variables.
The prevalence of school bullying was 16.40%. After adjustment, bullying involvement at baseline was associated with increased odds of subsequent poor OHRQoL (odds ratio, OR: 1.77, 95% CI: 1.50-2.11). Victims and bully-victims were seen significantly deteriorated OHRQoL, with ORs of 1.81 (95% CI: 1.50-2.19) and 2.10 (95% CI: 1.35-3.33). For different types of bullying victimization, only verbal victimization displayed a significant association with OHRQoL (OR: 2.07; 95% CI: 1.63-2.65). Bullying involvement was significantly associated with all four subdomains of OHRQoL, particularly for social well-being (OR: 1.91, 95% CI: 1.60-2.27). Stratified analyses revealed prominent effect modification by age, sex, ethnicity, and left-behind status in bullying-OHRQoL association.
Our findings suggest that children and adolescents who experienced school bullying had a significantly higher risk of subsequently poor OHRQoL, particularly for verbal victims. Targeted interventions should be designed and implemented.
校园欺凌对儿童和青少年的整体健康有负面影响，但欺凌与口腔健康相关生活质量（OHRQoL）之间的关联仍不明确。
在本研究中，采用两波前瞻性设计在中国西南部云南省收集数据。通过两阶段随机整群抽样，共纳入5346名10 - 17岁的儿童和青少年。采用单因素和多因素逻辑回归模型评估基线欺凌与随后的OHRQoL之间的顺序关联。进一步进行分层分析以评估重要人口统计学变量的效应修正。
校园欺凌的发生率为16.40%。调整后，基线时参与欺凌与随后OHRQoL较差的几率增加相关（优势比，OR：1.77，95%置信区间：1.50 - 2.11）。受害者和欺凌受害者的OHRQoL明显恶化，OR分别为1.81（95%置信区间：1.50 - 2.19）和2.10（95%置信区间：1.35 - 3.33）。对于不同类型的欺凌受害情况，只有言语受害与OHRQoL显示出显著关联（OR：2.07；95%置信区间：1.63 - 2.65）。参与欺凌与OHRQoL的所有四个子领域均显著相关，特别是社会幸福感（OR：1.91，95%置信区间：1.60 - 2.27）。分层分析显示，年龄、性别、种族和留守儿童状况在欺凌 - OHRQoL关联中具有显著的效应修正作用。
我们的研究结果表明，经历过校园欺凌的儿童和青少年随后OHRQoL较差的风险显著更高，尤其是言语受害者。应设计并实施针对性干预措施。
