Objective To investigate the prevalence of hearing impairment and ear diseases in presenium and senium in Guizhou province and to provide scientific data for drawing up the prevention and treatment strategies for deafness. Methods Using the probability proportion to size (PPS) method, 1554 people over 45 years old were investigated in 30 clusters in Guizhou province with the WHO protocol. Results Among ≥45 years old people, the prevalence of hearing impairment was 49.3% (the standardized rate: 47.5% in the whole country, 47.4% in Guizhou province). Degrees of hearing impairment were mild in 30.9%, moderate in 13.0%, severe in 4.5% and profound in 0.9% for hearing-impaired persons, respectively. The prevalence of hearing disability was 18.4%(the standardized rate: 18.5% in the whole country, 18.1% in Guizhou province). There were statistically significant differences of the prevalence between male and female, urban and rural, as well as different age groups. Among ≥60 years old people, the prevalence of hearing impairment was 72.6% and the prevalence of hearing disability was 29.9%. The causes of hearing impairment were ear diseases(28.6%), infectious diseases(0.1%), genetic condition(4.4%), non-infective condition(53.4%) and undetermined causes(24.3%). Of 1554 subjects, 498 persons needed intervention. Five point five percent of them needed medicine treatment, 26.2% of them needed hearing aids, 1.9% of them needed surgery and 1.2% of them needed other treatments. Conclusion Along with the advancement of social economy speeding up, the prevalence of the hearing impairment and disability in the presenium and senium also rised rapidly. With presbycusis accounting for a large proportion of the aged population, health care for the aged should be strenthened and the techniques of prevention and rehabilitation of hearing impairment should be enhanced to improve the quality of life and health level in old people.
