Abstract
Objective: To investigate the prevalence, severity of hearing disorders and demographics of people with hearing disorders based on the whole population in Jilin, Guangdong, Shannxi and Gansu provinces in China. Methods: According to " WHO Ear and Hearing Disorders Survey Protocol" , 144 clusters were chosen with probability proportional sampling(PPS) method from the four provinces covering 194, 688, 061 residents. Audiological test, otological examination and questionnaire surveying were conducted for all samples from August, 2014 to September, 2015. The hearing disorders were classified according to WHO criteria and classification. Results: Among 47 511 targeted residents, 45, 052 individuals (94.82% response rate) participated in the survey. The standardized prevalence rates of hearing disorders and disabling hearing disorders were 15.84 % and 5.17 % respectively. Almost 50% of people with hearing disorders had no awareness of it or its starting time. There was significant difference in the prevalence among people of different ages, genders, occupations, provinces, marital status and education levels. The prevalence of hearing disorders increased significantly as age grew. People above 60 years old occupied 55.31% of the total hearing disorders. The prevalence of hearing disorders among male, people of low education and those who lost husband or wife, as well as workers and farmers was relatively higher. Conclusions: The prevalence of hearing disorders is high, and hearing disorders are " invisible" . Demographics and socioeconomic factors significantly influence the prevalence of hearing disorders.
