“… 46 The high prevalence found herein agrees with the studies that indicate that the prevalence of hearing loss is higher in low- and intermediate-income countries, 47 and indicate socioeconomic factors associated with loss. 6 8 11 14 42 When investigating ear, nose and throat morbidities in school-age individuals in India, there was a significant association between the maternal education level and the search for health services directed to school-age individuals. 37 Herein no specific analysis was performed on schooling, however the education level of the head of household was considered in the economic evaluation proposed by the ABEP.…”

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.

“…Otitis media is a very common and costly disease in young children that can cause hearing loss and further lead to speech and reading difficulties (Cai & McPherson, ; Carroll & Breadmore, ; Khavarghazalani, Farahani, Emadi, & Hosseni Dastgerdi, ; le Clercq et al, ). Known risk factors for otitis media include young age, lack of breastfeeding, allergies, upper respiratory infection, second‐hand smoke, low social status, daycare attendance, multiple siblings, and family history (Brennan‐Jones et al, ; Y. Zhang et al, ).…”

A genetic basis for otitis media is established, however, the role of rare variants in disease etiology is largely unknown. Previously a duplication variant within A2ML1 was identified as a significant risk factor for otitis media in an indigenous Filipino population and in US children. In this report exome and Sanger sequencing was performed using DNA samples from the indigenous Filipino population, Filipino cochlear implantees, US probands, Finnish, and Pakistani families with otitis media. Sixteen novel, damaging A2ML1 variants identified in otitis media patients were rare or low-frequency in population-matched controls. In the indigenous population, both gingivitis and A2ML1 variants including the known duplication variant and the novel splice variant c.4061 + 1 G>C were independently associated with otitis media. Sequencing of salivary RNA samples from indigenous Filipinos demonstrated lower A2ML1 expression according to the carriage of A2ML1 variants. Sequencing of additional salivary RNA samples from US patients with otitis media revealed differentially expressed genes that are highly correlated with A2ML1 expression levels. In particular, RND3 is upregulated in both A2ML1 variant carriers and high-A2ML1 expressors. These findings support a role for A2ML1 in keratinocyte differentiation within the middle ear as part of otitis media pathology and the potential application of ROCK inhibition in otitis media.

“…There were also limitations. Like other population studies,2 25 we lacked bone conduction audiometry owing to the field logistics of a ‘whole participant’ assessment, with hearing just one of multiple health domains. However, our sensitivity analyses indicated that middle ear status likely had little influence (online supplementary figure S1 and table S2).…”

Academic, behavioural and quality of life outcomes of slight to mild hearing loss in late childhood: a population-based study

ObjectiveTo investigate the associations of hearing thresholds and slight to mild hearing loss with academic, behavioural and quality of life outcomes in children at a population level.MethodsDesign and participants:children aged 11–12 years in the population-based cross-sectional Child Health CheckPoint study within the Longitudinal Study of Australian Children. Audiometry:mean hearing threshold across 1, 2 and 4 kHz (better and worse ear); slight/mild hearing loss (threshold of 16–40 decibels hearing loss (dB HL)). Outcomes: National Assessment Program – Literacy and Numeracy, language, teacher-reported learning, parent and teacher reported behaviour and self-reported quality of life. Analysis:linear regression quantified associations of hearing threshold/loss with outcomes.ResultsOf 1483 children (mean age 11.5 years), 9.2% and 13.1% had slight/mild bilateral and unilateral hearing loss, respectively. Per SD increment in better ear threshold (5.7 dB HL), scores were worse on several academic outcomes (eg, reading 0.11 SD, 95% CI 0.05 to 0.16), parent-reported behaviour (0.06 SD, 95% CI 0.01 to 0.11) and physical (0.09 SD, 95% CI 0.04 to 0.14) and psychosocial (0.06 SD, 95% CI 0.01 to 0.11) Pediatric Quality of Life Inventory (PedsQL). Compared with normally hearing children, children with bilateral slight/mild losses scored 0.2–0.3 SDs lower in sentence repetition, teacher-reported learning and physical PedsQL but not other outcomes. Similar but attenuated patterns were seen in unilateral slight/mild losses.ConclusionsHearing thresholds and slight/mild hearing loss showed small but important associations with some child outcomes at 11–12 years. Justifying hearing screening or intervention at this age would require better understanding of its longitudinal and indirect effects, alongside effective management and appropriate early identification programmes.
