The objective was to evaluate differences between prevalence rates for self-reported hearing loss and associated factors, obtained from responses by primary and proxy informants in a Population-Based Study on Human Communication Disorders (DCH-POP in Portuguese). This was a study on epidemiological methods using data from a cross-sectional household survey with a sample of 1,253 individuals from Southern Brazil. To verify differences between prevalence rates comparing primary informants and proxy informants, we used the chi-square or Fisher's exact test for categorical variables and Mann-Whitney for continuous variables. The log-binomial model was adjusted for hearing loss as the dependent variable, considering three datasets: the entire sample, only primary informants, and only proxy informants, estimating association by prevalence ratios. In the final models, only the independent variables age and dizziness were associated with hearing loss, independently of the dataset that was used. Proxy informants generally underestimated the prevalence rates for the target outcomes, when compared to primary informants.
目的是评估在一项关于人类交流障碍的基于人群的研究（葡萄牙语为DCH-POP）中，通过主要信息提供者和代理信息提供者的回答所获得的自我报告听力损失患病率及相关因素之间的差异。这是一项关于流行病学方法的研究，使用了来自巴西南部1253名个体的横断面家庭调查数据。为了验证比较主要信息提供者和代理信息提供者患病率之间的差异，我们对分类变量使用卡方检验或费舍尔精确检验，对连续变量使用曼-惠特尼检验。以听力损失为因变量，对对数二项模型进行了调整，考虑了三个数据集：整个样本、仅主要信息提供者和仅代理信息提供者，通过患病率比估计关联。在最终模型中，仅年龄和头晕这两个自变量与听力损失相关，与所使用的数据集无关。与主要信息提供者相比，代理信息提供者通常低估了目标结果的患病率。
