To analyze factors associated with the prevalence of the medical diagnosis of vocal fold pathologies in teachers.
A census-based epidemiological, cross-sectional study was conducted with 4,495 public primary and secondary school teachers in the city of Salvador, Northeastern Brazil, between March and April 2006. The dependent variable was the self-reported medical diagnosis of vocal fold pathologies and the independent variables were sociodemographic characteristics; professional activity; work organization/interpersonal relationships; physical work environment characteristics; frequency of common mental disorders, measured by the Self-Reporting Questionnaire-20 (SRQ-20 >7); and general health conditions. Descriptive statistical, bivariate and multiple logistic regression analysis techniques were used.
The prevalence of self-reported medical diagnosis of vocal fold pathologies was 18.9%. In the logistic regression analysis, the variables that remained associated with this medical diagnosis were as follows: being female, having worked as a teacher for more than seven years, excessive voice use, reporting more than five unfavorable physical work environment characteristics and presence of common mental disorders.
The presence of self-reported vocal fold pathologies was associated with factors that point out the need of actions that promote teachers' vocal health and changes in their work structure and organization.
分析与教师声带病变医学诊断患病率相关的因素。
2006 年 3 月至 4 月，在巴西东北部萨尔瓦多市对 4495 名公立小学和中学教师进行了一项基于普查的流行病学、横断面研究。因变量是自我报告的声带病变的医学诊断，自变量包括社会人口特征；职业活动；工作组织/人际关系；物理工作环境特征；常见精神障碍的频率，通过自我报告问卷-20（SRQ-20＞7）进行测量；和一般健康状况。采用描述性统计、双变量和多因素逻辑回归分析技术。
自我报告的声带病变医学诊断的患病率为 18.9%。在逻辑回归分析中，与该医学诊断相关的变量如下：女性，从事教师工作超过七年，过度使用声音，报告超过五个不利的物理工作环境特征以及存在常见精神障碍。
自我报告的声带病变与表明需要采取行动促进教师的声带健康以及改变其工作结构和组织的因素有关。
