香港社区人群中口腔颌面部疼痛与异常疾病行为的相关性

The association between orofacial pain and abnormal illness behavior in the community in Hong Kong

目的探讨香港人群中口腔颌面部疼痛(OFP)与异常疾病行为的相关性。方法本研究为在社区人群中进行的横断面的病例-对照研究。研究样本为注册在香港医院管理局/香港大学家庭医学部的35～70岁香港居民。通过面对面问诊结合临床检查了解受访者在过去1个月中口腔颌面部疼痛的状况。疾病行为由30条的患病行为问卷(IBQ-30)进行评估。结果 200名有口腔颌面部疼痛症状的人及200名没有痛症的人参加本研究。口腔颌面部疼痛与IBQ-30量表中的5个分量表(一般疑病、疾病信念、情感紊乱、否认心理问题、易激惹)相关性有统计学意义(P<0.001)。在有痛症的人中,在否认心理问题分量表,老年组高分值的人数明显多于中年组(P=0.034)。口腔颌面部疼痛症状不同临床分组的IBQ-30分值差异无统计学意义。结论口腔颌面部疼痛与异常疾病行为显著相关,在治疗口腔颌面部疼痛病症患者时,需考虑衡量精神心理因素所起的作用。

Objective To investigate the associations between orofacial pain（OFP） symptoms and illness behavior in the community-dwelling people in Hong Kong.Methods A community-based,cross-sectional case-control study involving people aged 35-70 registered with the Hospital Authority/University of Hong Kong Family Medicine Clinic served as the sampling frame.People with recent OFP symptoms and a group without such symptoms were participated.Standard questions were asked about OFP conditions in the previous month.Illness behavior was assessed using the 30-item Illness Behavior Questionnaire（IBQ-30）.Results Two hundred people with OFP symptoms and 200 without OFP took part.OFP was statistically related to 5 of 7 sub-scales of the IBQ-30（P 0.001）：general hypochondriasis,disease conviction,affective disturbance,denial,and irritability.Differences in percentage distribution of IBQ-30 scores between different age groups were only detected in the sub-scale of denial with more elderly respondents with pain（55.0% vs 38.0%,P = 0.034）.Illness behaviour did not appear to be related to clinical classification of OFP.Conclusions OFP was significantly associated with illness behavior.Findings have clinical implication for effective management of OFP.
