Pure-tone thresholds are used to estimate hearing acuity and, when measured longitudinally, can characterize age-related changes in hearing. Measured at multiple-frequencies, multiple-irregular time points, for right and left ears, these longitudinal studies of age-related hearing loss produce data of inherent complexity due to: 1) multivariate outcomes at different frequencies; 2) longitudinal measurements taken at subject-specific time intervals; and 3) inter-ear correlations due to clustering and nesting. To address limitations in existing methods, we propose a multivariate generalized linear mixed model(mGLMM) and assess its performance. We demonstrate its application using a unique dataset from a cohort study of age-related hearing loss.
纯音阈值用于评估听力敏锐度,纵向测量时可表征与年龄相关的听力变化。这些关于年龄相关性听力损失的纵向研究在多个频率、多个不规则时间点对左右耳进行测量,由于以下原因产生了具有内在复杂性的数据:1)不同频率下的多变量结果;2)在个体特定时间间隔进行的纵向测量;3)由于聚类和嵌套导致的耳间相关性。为了解决现有方法的局限性,我们提出了一种多变量广义线性混合模型(mGLMM)并评估其性能。我们使用来自一项年龄相关性听力损失队列研究的独特数据集展示了它的应用。
