“…by ease of treatment, by better ear). Previous all-age surveys of hearing loss have provided scarce details on the methods of assigning cause in the individual despite presenting data in this way [43,47]. Further attention into the most useful way to report data for planning purposes is also required.…”

Background: The Rapid Assessment of Hearing Loss (RAHL) survey protocol aims to measure the prevalence and causes of hearing loss in a low cost and rapid manner, to inform planning of ear and hearing services. This paper reports on the first field-test of the RAHL in Gao'an County, Jiangxi Province, China. This study aimed to 1) To report on the feasibility of RAHL; 2) report on the estimated prevalence and causes of hearing loss in Gao'an. Methods: A cross-sectional population-based survey was conducted in September-October 2018. Forty-seven clusters in Gao'an County were selected using probability-proportionate-to-size sampling. Within clusters, compact segment sampling was conducted to select 30 people aged 50+. A questionnaire was completed covering sociodemographics, hearing health, and risk factors. Automated pure-tone audiometry was completed for all participants, using smartphone-based audiometry (hearTest), at 0.5, 1, 2, 4 kHz (kHz). All participants had their ears examined by an Ear Nose and Throat (ENT) doctor, using otoscopy, and probable causes of hearing loss assigned. Prevalence estimates were age and sex standardised to the Jiangxi population. Feasibility of a cluster size of 30 was examined by assessing the response rate, and the proportion of clusters completed in 1 day. Results: 1344 of 1421 eligible participants completed the survey (94.6%). 100% of clusters were completed in 1 day. The survey was completed in 4.5 weeks. The prevalence of moderate or greater hearing loss (pure-tone average of 0.5, 1, 2, 4 kHz of > = 41dBHL in the better ear) was 16.3% (95% CI = 14.3, 18.5) and for any level of hearing loss (pure-tone average of > = 26dBHL in the better ear) the prevalence was 53.2% (95% CI = 49.2, 57.1). The majority of hearing loss was due to acquired sensorineural causes (91.7% left; 92.1% right). Overall 54.0% of the population aged 50+ (108,000 people) are in need of diagnostic audiology services, 3.4% were in need of wax removal (7000 people), and 4.8% were in need of surgical services (9500 people). Hearing aid coverage was 0.4%. Conclusion: The RAHL survey protocol is feasible, demonstrated through the number of people examined per day, and the high response rate. The survey was completed in a much shorter period than previous all-age surveys in China. Some remaining challenges included assignment of causes of probable sensorineural loss. The data obtained from this survey can be used to scale-up hearing services in Gao'an.

Introduction Hearing loss interferes in the development of language and verbal capacities, which causes learning difficulties and deleterious effects. Objective To analyze the prevalence and associated factors for hearing loss in school-age individuals of the municipality of Natal, state of Rio Grande do Norte, Northeast Brazil. Methods Cross-sectional study that evaluated 238 school-age individuals (6–17 years old) in municipal public schools. Meatoscopy was performed and school-age individuals answered the questions “Do you think that you hear well?” and “Do you have earaches?”. Auditory evaluation was performed with a Telessaúde audiometer. The responsible adults answered socioeconomic, speech and audiology aspects and risk factors for hearing loss questionnaire. Results The prevalence of hearing loss was 16% (11.7–21.4%); 16% reported not to hear well, 18.9% reported earaches, and 26.1% presented altered meatoscopy. The prevalence of hearing loss was higher in school-age individuals who reported hearing difficulties, in children between the ages of 6 and 12, and with altered meatoscopy results (p < 0.05). Airway infection (PR = 3.37; 95% confidence interval [CI]: 1.48–7.68) was found as a risk factor associated with hearing loss, remaining significant in the multivariate model (PR = 6.79; 95%CI: 1.98–23.26; p = 0.002). Conclusions Hearing loss in this sample is above the values reported in other studies performed in Brazil for this age group. This highlights the necessity of better structure of speech and audiology attention, so that auditory health promotion actions can be systematized for this population.
