BackgroundPresbyacusis is the most common type of hearing loss, oftenhaving profound effects on the quality of life in old age.The objectives of this study were:1. To analyse of the effect of demographic factors onpresbyacusis in Sri Lanka.2. To quantify the effect of non-demographic risk factors onpresbyacusis.MethodAn observational cross-sectional study was carried outinvolving all the patients who presented to the NationalHospital ENT clinic with hearing loss between April 2007 andApril 2010. Patients whose pure-tone audiometry resultswere suggestive of sensorineural hearing deficit and whosetympanometry testing did not show any middle earproblems were assessed using an interviewer-administeredquestionnaire.ResultsAmong the 567 participants studied, the mean age was63.4yrs. Fifty eight percent were females. The majority ofthe patients were from the Colombo district (59.3%),however, participants came from ten districts of Sri Lanka.Most of the study participants (64.2%) were married andliving with their partners, but 24.7% were widowed and therest were either unmarried or divorced. 6.1% hadcommunication difficulties leading to disrupted socialrelationships and 21% felt that hearing impairment (HI) hadadversely affected their psychological well-being. The onsetof impaired hearing, as perceived by the patients initiallyand later confirmed by pure-tone audiometry andtymanometry, had occurred at an average age of 62.9yrs.ConclusionThere was no significant association between presbyacusisand other demographic factors such as gender, educationlevel and marital status. A significant proportion of theparticipants had been widowed and that fact, too, canreduce their quality of life.
