“…The prevalences of hearing loss for the other two Asian Tigers (ie, Singapore and Hong Kong) were slightly higher, at 14.6% (95% CI 10.0-19.2) and 15.3% (95% CI 10.3-20.4), respectively. The high prevalence of hearing loss in India, which, along with Pakistan and Bangladesh, is one of the most populated countries in the world, is supported by the findings of Garg et al [ 33 ]. Similar hearing loss prevalences were found in most Western and Central European countries, which were slightly higher than Australia (11.4%, 95% CI 9.8-13.0) and Canada (12.2%, 95% CI 10.4-13.9) but lower than that in the United States (14.6%, 95% CI 13.9-15.4).…”

Background In addition to the aging process, risk factors for hearing loss in adults include, among others, exposure to noise, use of ototoxic drugs, genetics, and limited access to medical care. Differences in exposure to these factors are bound to be reflected in the prevalence of hearing loss. Assessment of hearing loss can easily be carried out on a large scale and at low cost using mobile apps. Objective This study aimed to conduct a worldwide assessment of the differences in hearing loss prevalence between countries in a group of mobile device users. Methods Hearing tests were conducted using the open-access Android-based mobile app Hearing Test. The app is available free of charge in the Google Play store, provided that consent to the use of the results for scientific purposes is given. This study included hearing tests carried out on device models supported by the app with bundled headphones in the set. Calibration factors for supported models were determined using the biological method. The tests consisted of self-determining the quietest audible tone in the frequency range from 250 Hz to 8 kHz by adjusting its intensity using the buttons. The ambient noise level was optionally monitored using a built-in microphone. Following the test, the user could compare his hearing threshold against age norms by providing his or her age. The user's location was identified based on the phone’s IP address. Results From November 23, 2016 to November 22, 2019, 733,716 hearing tests were conducted on 236,716 mobile devices across 212 countries. After rejecting the tests that were incomplete, performed with disconnected headphones, not meeting the time criterion, repeated by the same user, or carried out regularly on one device, 116,733 of 733,716 tests (15.9%) were qualified for further analysis. The prevalence of hearing loss, defined as the average threshold at frequencies 0.5 kHz, 1 kHz, 2 kHz, and 4 kHz above 25 dB HL in the better ear, was calculated at 15.6% (95% CI 15.4-15.8). Statistically significant differences were found between countries (P<.001), with the highest prevalences for Bangladesh, Pakistan, and India (>28%) and the lowest prevalences for Taiwan, Finland, and South Korea (<11%). Conclusions Hearing thresholds measured by means of mobile devices were congruent with the literature data on worldwide hearing loss prevalence. Uniform recruitment criteria simplify the comparison of the hearing loss prevalence across countries. Hearing testing on mobile devices may be a valid tool in epidemiological studies carried out on a large scale.

“… 17 In Finland, a population-based HI study involving 55–64-year-old adults reported that the prevalence of HI was 18.4%. 18 However, the prevalence of HI among ≥65 years old women in Brazil was 39.4%, 19 and the total prevalence of HI was 38.8% in rural India, 20 which was much higher than that in developed countries. Previous studies have indicated that the level of economic development affects the prevalence of HI.…”

Objective Hearing impairment (HI) has become one of the most common causes of disability worldwide. To date, few studies have examined the hearing of women in these frequently rural regions. Thus, we explored the HI prevalence and risk factors among low-income, middle-aged, and elderly women in Tianjin, China. Methods Between October and November 2013, female residents aged ≥45 years of rural Tianjin, China were recruited into the study. The participants completed questionnaire surveys, physical examinations, and hearing tests. The hearing at frequencies of 500 Hz, 1000 Hz, 2000 Hz, and 4000 Hz was used to analyze the hearing characteristics of specific frequency bands, and HI was defined as the better ear pure tone averages (PTA) >25 dB HL. Results Among the 1416 participants, the prevalence of HI was 46.0%. Among those aged 45–54-years, most (65.3%) demonstrated normal hearing; in other age groups, slight HI accounted for the largest proportions of individuals. Compared with women who did not drink, the odds ratio (OR) of HI among women who consumed alcohol was 4.2 (95% confidence interval [CI]: 1.844–9.574; P = 0.001). Compared with pre-menopausal women, the OR of HI among postmenopausal women was 1.8 (95% CI: 1.261–2.667; P = 0.001). Further, each 1-year increase in age in women resulted in a 7.1% increase in HI risk (P < 0.001). Conclusion The burden of HI among women is heavy in rural northern China, especially among those who experienced menopause. Additionally, the results suggest that to further reduce the risk of developing HI, women in rural areas should stop consuming alcohol. The problem of HI among women in rural areas should be taken seriously; moreover, the measures implemented to prevent HI in high-risk women should be strengthened.

“…The prevalence of HL ranged from 6% to 26.9% and DHL ranged from 4.5% to 18.32%. [32][33][34][36][37][38][39][40][41] The largest of these studies was conducted by the Indian Council of Medical Research (ICMR) in 1983, 33 which reported a prevalence of 10.2%. Studies with a smaller sample size reported a higher prevalence.…”

“…The rural population had higher HL numbers across all studies. 33,34,36,37,[39][40][41] The difference in rural and urban areas when evaluating DHL was smaller but substantial nonetheless 36,37,39,40 (Table V). Predictably, older populations had higher prevalence of hearing impairment compared to the young.…”

“…A slower rise in HL till the age of 45-50 years was noticed, beyond which there was a sharp increase in prevalence. Beyond 60-65 years of age, HL was present in more than half and DHL in more than a quarter of the population [35][36][37][38][39][40][41] (Table VI); 39.3%-57.5% of all HL sufferers were more than 60 years old. The risk of HL in a noisy work environment (>85 dB) was also significantly higher.…”

Background Despite abundant literature, a clear and coherent understanding of hearing loss (HL) in India is limited by the wide disparity in studies. Methods We did a review of published peer-reviewed journal articles. Studies reporting the prevalence and degree of HL in India from 1980 to 2020 were included. Information was gathered on the population characteristics, methodology applied and the prevalence of hearing impairment. The data were analysed to identify trends and at-risk sections of population in various categories. Results Four hundred and forty studies were identified after a database search; 29 full-length articles were selected for final analysis. Using a 3-step screening protocol, hearing impairment (abnormal auditory brainstem response/auditory steady state response) in neonates ranged between 1.59 and 8.8 per 1000 births. Among ‘at risk’ neonates, it ranged from 7 to 49.18 per 1000 births. In children the prevalence of HL was 6.6% to 16.47%. Otitis media was the most common cause of HL in children. Community-based studies (all ages) reported prevalence of HL between 6% and 26.9% and prevalence of disabling HL between 4.5% and 18.3%. Rural areas and elderly showed a higher prevalence of hearing impairment. Conclusion Despite India’s improving health indices, hearing disability remains persistently high. It is a major contributor to the loss of personal potential and a financial strain for the individual and the country. A large-scale multicentric study to identify the degree and type of HL, social awareness campaigns, widespread neonatal screening, strengthening treatment facilities and well-funded rehabilitation programmes can counter the rising prevalence of hearing impairment.
