This dataset was from a study published in the American Journal of Epidemiology, titled, “Tracking Population Health Based on Self-reported Impairments: Trends in the Prevalence of Hearing Loss in US Adults, 1976–2006.” This study conducted interviews and hearing loss tests from four nationally representative surveys between 1976 and 2006 on men and women aged 20-69. The research team developed a methodology for standardizing the surveys and used all available data to find the true trend in hearing loss reduction.
Results showed that there is significant underreporting or overreporting of hearing loss was observed, with various patterns of bias across age groups and surveys. Hearing loss prevalence was stable in both sexes in the early 2000s. Tracking the prevalence of hearing loss over time is essential for formulation and evaluation of policies to improve hearing status in the population. In addition, strategies to promote prevention of hearing loss at work and in communities are to reducing the burden of hearing loss.
