To assess the relationship between Intimate partner violence (IPV) (a highly prevalent form of domestic abuse) with the subsequent development of temporomandibular joint disorder (TMD).
A retrospective open cohort study using a UK primary care database was undertaken. 18,547 women exposed to IPV were matched by age to 74,188 unexposed women. Defined through clinical codes the outcome of interest was TMD, and adjusted incidence rates (aIRR) were used to describe the relationship after considering covariates of interest.
94 individuals in the exposed group were clinically coded with TMD during the study period translating to an incidence rate (IR) or 1.59 per 1000 person years. This was in comparison to 342 outcomes in the unexposed group (IR 1.21 per 1000 person years). The unadjusted IRR was 1.31 (95% CI 1.04-1.65; p < 0.020) and after adjustment for important covariates increased to 1.45 (95% CI 1.14-1.84; p < 0.002).
Our results suggest that the development of TMD may be associated with exposure to IPV in women.
In the first cohort to do so, we have identified a moderate association between Intimate partner violence exposure and subsequent development of TMD. This highlights an opportunity for screening of abuse in individuals presenting with TMD.
评估亲密伴侣暴力（IPV）（一种普遍存在的家庭暴力形式）与颞下颌关节紊乱（TMD）随后发展之间的关系。
采用英国初级保健数据库进行回顾性开放队列研究。将 18547 名暴露于 IPV 的女性按年龄与 74188 名未暴露于 IPV 的女性相匹配。通过临床代码定义感兴趣的结局为 TMD，并在考虑感兴趣的协变量后使用调整后的发病率（aIRR）来描述关系。
暴露组中有 94 人在研究期间临床诊断为 TMD，发病率（IR）为每 1000 人年 1.59 例。而未暴露组中有 342 例（IR 为每 1000 人年 1.21 例）。未调整的 aIRR 为 1.31（95%CI 1.04-1.65；p<0.020），调整重要协变量后增加到 1.45（95%CI 1.14-1.84；p<0.002）。
我们的结果表明，TMD 的发展可能与女性暴露于 IPV 有关。
在第一个这样做的队列中，我们已经确定了 IPV 暴露与随后发生的 TMD 之间存在中度关联。这突出了在 TMD 患者中筛查虐待的机会。
