Prevalence and Risk Factors of Hearing Loss at Bugando Medical Centre Mwanza Tanzania

Abstract

Hearing enable us to communicate and interact all over the world. When hearing is reduced or not there at all then is a major problem. In Africa more so in the Sub Sahara, this problem is on the rise due to the activities that are been carried out. There is no clinical data that is available from our national and zonal referral hospital, this study is a stepping stone for more studies. The outcome will show the burden of the people with reduced or has no ability to hear, distribution of hearing loss and the contributing factors. The engagement was conducted in a tertiary hospital serving more than five regions of the country. It`s a descriptive cross-sectional study. The study spanned from July 2020 to December 2020 with the total number of patients visited the otorhinolaryngology and audiology clinic being 6,234 the ones hearing loss 526. The study found prevalence of 8.4% for reduce/inability to hear. Females found to be more by 1.3%. Sensorineural hearing was the leading (51%), followed by conductive hearing (41%). The group most affected by sensorineural hearing were 40-59 (53.7%). On conductive hearing, the leading group being affected were 3-39 years (46.6%). In the distribution of sensorineural hearing the leading one was mild hearing in the age group of 3-39 (63%), followed by moderate hearing at 25.5%. The contributory factors were inflammation, such as allergic rhinitis (38%), otitis (34%), and wax (9.5). These factors contributed to about 60% of hearing loss. A group of young adults have been found to have mild hearing (63%); this shows that in a few years, the majority of the young group will have severe hearing problems, hence decreasing the manpower of our economy. Public knowledge about ear care should be offered to people, and this should be done by the media and the health sector as a whole
