A cross sectional study on prevalence of hearing loss and related factors in rural and urban areas of Delhi- Implementation of WHO survey protocol

Background: According to the World Health Organization, it is estimated that about 360 million individuals in the world have disabling hearing loss, of which 91% are adults and 9% are children. Aim: To determine the prevalence and causes of hearing loss among people aged 3 months and above in selected areas of Delhi and to determine the socio-demographic correlates of hearing loss in the study population using WHO handbook on Survey for prevalence and causes of hearing loss. Methods A community based cross sectional study was conducted in rural and urban areas of Delhi among 650 individuals. Study population was constituted by individuals aged 3 months and above of selected areas of Delhi. All residents of selected areas who were 3 months and older who gave informed consent for participation in the study were included. Participants who were unable to follow simple commands or unable to remain alert during the duration of the hearing test device or with any other physical or mental disability where air conduction audiometry was not possible were excluded. Data was collected by door to door survey. All members of selected household were included after taking written informed consent. Demographic details and relevant history assessing the hearing loss or any exposure to conditions predisposing to hearing loss were collected. Findings of ear examination on otoscopy and tympanometry were noted. OAE was done in under five children. Protocol was approved by Institutional Ethics Committee. Findings The overall prevalence of hearing loss ranged from 6-40% in study subjects. Lack of adequate space, control of background noise – sound proof room requirement, availability of ENT personnel, availability of audiologist and difficulty in mobilizing community and follow up visits and to motivate health workers were major barriers.

  • To determine the prevalence and causes of hearing loss among people aged 3 months and above in selected areas of Delhi.
  • To determine the socio-demographic correlates of hearing loss in the study population.
  • To test the feasibility of revised WHO handbook on Survey for prevalence and causes of hearing loss.
