To analyze the influence of socioeconomic and demographic factors (gender, economic class, age and marital status) on the occurrence of temporomandibular disorder.
One hundred individuals from urban areas in the city of Recife (Brazil) registered at Family Health Units was examined using Axis I of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) which addresses myofascial pain and joint problems (disc displacement, arthralgia, osteoarthritis and oesteoarthrosis). The Brazilian Economic Classification Criteria (CCEB) was used for the collection of socioeconomic and demographic data. Then, it was categorized as Class A (high social class), Classes B/C (middle class) and Classes D/E (very poor social class). The results were analyzed using Pearson's chi-square test for proportions, Fisher's exact test, nonparametric Mann-Whitney test and Binary logistic regression analysis.
None of the participants belonged to Class A, 72% belonged to Classes B/C and 28% belonged to Classes D/E. The multivariate analysis revealed that participants from Classes D/E had a 4.35-fold greater chance of exhibiting myofascial pain and 11.3-fold greater chance of exhibiting joint problems.
Poverty is a important condition to exhibit myofascial pain and joint problems.
分析社会经济和人口统计学因素（性别、经济阶层、年龄和婚姻状况）对颞下颌关节紊乱症发生的影响。
对在累西腓市（巴西）市区家庭健康单位登记的100名个体，使用颞下颌关节紊乱症研究诊断标准（RDC/TMD）的轴I进行检查，该标准涉及肌筋膜疼痛和关节问题（盘移位、关节痛、骨关节炎和骨关节病）。采用巴西经济分类标准（CCEB）收集社会经济和人口统计学数据。然后，将其分为A类（高社会阶层）、B/C类（中产阶级）和D/E类（非常贫困的社会阶层）。使用Pearson卡方检验比例、Fisher精确检验、非参数Mann-Whitney检验和二元逻辑回归分析对结果进行分析。
没有参与者属于A类，72%属于B/C类，28%属于D/E类。多变量分析显示，来自D/E类的参与者出现肌筋膜疼痛的几率高4.35倍，出现关节问题的几率高11.3倍。
贫困是出现肌筋膜疼痛和关节问题的一个重要条件。
