Abstract
OBJECTIVE To assess the feasibility of implementing a school entry hearing screening programme in the South-East District, Botswana. DESIGN A feasibility study design was used. Trained screeners conducted smartphone-based pure tone audiometry screening at 25 dB HL, at 1, 2, and 4 kHz using calibrated headphones. Learners with "refer" results after an immediate rescreen were referred and scheduled for diagnostic hearing assessment at the local hospital. Attendance at diagnostic appointments was encouraged through multiple contacts with the families. STUDY SAMPLE The study participants were 403 Grade 1 learners from eight public primary schools. RESULTS The overall referral rate for diagnostic hearing assessment was 4.7%, with a referral uptake rate of 90%. The sensitivity and specificity of the hearing screening protocol were 93.3% and 86.4%, respectively. The positive and negative predictive values were 82.4% and 95%, respectively. The average cost per learner screened was US$ 10.75. CONCLUSIONS School entry hearing screening programmes can be successfully implemented in the South-East District, Botswana. Lessons learnt from this study can potentially guide phased implementation of school hearing screening programmes in other districts.

Xiao H, Amaerjiang N, Wang W, Li M, Zunong J, En H, Zhao X, Wen C, Yu Y, Huang L, Hu Y. Hearing thresholds elevation and potential association with emotional problems among 1,914 children in Beijing, China. Front Public Health 2022; 10:937301. [PMID: 35991012 PMCID: PMC9386347 DOI: 10.3389/fpubh.2022.937301] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Accepted: 07/12/2022] [Indexed: 01/09/2023] Open
Abstract
Objectives School-aged children may experience hearing loss and emotional problems. Previous studies have shown a bidirectional relationship between hearing loss and emotional problems in the elderly population, and we aimed to analyze the association between hearing thresholds and emotional problems in school-aged children. Methods Based on the Beijing Child Growth and Health Cohort (PROC) study, the hearing screenings were conducted in November 2019 using pure tone audiometry. A total of 1,877 parents completed the Strengths and Difficulties Questionnaire (SDQ) to assess children's emotional and behavioral status. We used generalized linear regression analysis to assess the potential association of emotional problems with hearing thresholds, based on multiple imputed datasets with a sample size of 1,914. Results The overall pass rate of hearing screening was 91.5%. The abnormal rate of SDQ total difficulties was 55.8%. Emotional symptoms were positively associated with left ear average hearing thresholds (β = 0.24, 95%CI: 0.08-0.40), and right ear average hearing thresholds (β = 0.18, 95%CI: 0.04-0.32). Conduct problems, hyperactivity/inattention, peer problems, and prosocial behaviors had no association with the pass rate of the hearing screening. Regarding emotional symptoms, boys with many fears and who are easily scared coincided with increased right ear average hearing thresholds (β = 0.67, 95%CI: 0.01-1.33). Girls having many worries, frequently feeling unhappy and downhearted were positively associated with left and right ear average hearing thresholds, respectively (β = 0.96, 95%CI: 0.20-1.73; β = 0.72, 95%CI: 0.07-1.37). Conclusions The co-occurrence of hearing problems and emotional problems of children aged 6-8 in Beijing attracts attention. It is important to address undiscovered hearing loss and emotional problems from the perspective of comorbidity driving factors.

[PMID: 34854541 PMCID: PMC8712396 DOI: 10.1002/pbc.29437] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/19/2021] [Revised: 09/30/2021] [Accepted: 10/19/2021] [Indexed: 02/03/2023]
Abstract
BACKGROUND We sought to estimate the frequency of hearing screening failures in pediatric cancer survivors at low risk for hearing loss and evaluate the feasibility of administering screenings in this population. PROCEDURE Survivors in the St. Louis Children's Hospital Late Effects Clinic were recruited. Eligibility included (a) diagnosis of a pediatric cancer treated without platinum chemotherapy or cranial radiation, (b) at least 6 months from completion of therapy, (c) between the ages of 7 and 18 years, (d) cognitively/behaviorally able to participate, and (e) English speaking. Behavioral hearing screenings from 1000 to 8000 Hz were performed by trained personnel using a calibrated audiometer. A failed screen was defined by a participant not responding to two or more of the three screening attempts for at least one frequency in at least one ear. RESULTS One hundred nine patients met eligibility criteria with 78 enrolled (71.5%). Diagnoses included leukemia (57.7%), sarcoma (11.5%), Wilms tumor (14.1%), lymphoma (12.8%), and other solid tumors (3.9%). The median age was 13.2 years (Q1-Q3: 9.6-15.4) and the median time from treatment completion was 3.7 years (Q1-Q3: 2.3-7.4). Eighteen patients (23%) failed the hearing screen (95% CI: 14%-34%). No demographic or treatment-related variables were significantly correlated to screening failure. Six screen failures (33%) underwent formal audiology assessments, with three demonstrating unilateral hearing loss: two conductive and one sensorineural. CONCLUSIONS A significant fraction of pediatric cancer survivors at low risk for hearing loss failed hearing screening. Broader use of hearing screening should be considered.

Prevalence and characteristics of hearing and vision loss in preschool children from low income South African communities: results of a screening program of 10,390 children. BMC Pediatr 2022; 22:22. [PMID: 34986809 PMCID: PMC8728966 DOI: 10.1186/s12887-021-03095-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Accepted: 12/23/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The majority of children with sensory impairments live in low- and middle-income countries. More studies of hearing and vision impairment prevalence are needed, in order to generate more accurate estimates of trends in sensory impairments. This study aimed to estimate the prevalence and describe the characteristics of hearing and vision loss among preschool children (4-7 years) in an underserved South African community following community-based mobile health (mHealth) supported hearing and vision services. METHODS A screening program of sensory impairments was undertaken of children attending preschools in the communities of Khayelitsha and Mitchell's Plain, Cape Town, from September 2017 until June 2019. Hearing and vision screening were done by trained community health workers using mHealth technology. Children who failed hearing and vision screening were seen for follow-up assessments at their preschools. Follow-up assessments were conducted using smartphones that host point-of-care validated and calibrated hearing and vision testing applications (hearTest app, hearX Group, South Africa and PeekAcuity app, Peek Vision, United Kingdom). Descriptive statistical analysis and logistic regression analysis were conducted after extracting data from a secure cloud-based server (mHealth Studio, hearX Group) to Microsoft Excel (2016). RESULTS A total of 10,390 children were screened at 298 preschools over 22 months. Of the children screened, 5.6 and 4.4% of children failed hearing and vision screening respectively. Community-based follow-up hearing tests were done at the preschools on 88.5% (514) of children of whom 240 children (54.2% female) presented with hearing loss. A preschool-based follow-up vision test was done on 400 children (88.1%). A total of 232 children (46.1% female) had a vision impairment, and a further 32 children passed the test but had obvious signs of ocular morbidity. Logistic regression analysis found that age was a significant predictor of vision loss (p < 0.05), but not for hearing loss (p = 0.06). Gender was not a significant predictor of hearing (p = 0.22) or vision loss (p = 0.20). CONCLUSIONS Hearing loss is prevalent in at least 22 per 1000 and vision loss in at least 23 per 1000 preschool children in an underserved South African community. Timely identification of sensory losses can be facilitated through community-based hearing and vision services supported by mHealth technology.

Abstract
OBJECTIVE To determine if hearScreen®, a smartphone-based pure tone audiometric screen, serves as an effective hearing screen for identifying hearing loss in children at risk, such as those with chronic otitis media and/or craniofacial anomalies. METHODS A cross-sectional, single-center, prospective study at an urban tertiary care hospital was completed. From June to October 2019, a total of 208 pediatric ears at risk for hearing loss were evaluated by both hearScreen® and conventional pure tone audiometry. The efficacy of hearScreen® for detecting hearing loss in a pediatric population at risk was determined. RESULTS A total of 208 pediatric ears at risk for hearing loss were screened. HearScreen® demonstrated a sensitivity of 85%, a specificity of 41%, a positive predictive value of 36%, and a negative predictive value of 87%. Subgroup analysis stratified by hearing loss type showed that hearScreen® screens for conductive hearing loss with increased sensitivity. CONCLUSIONS This investigation suggests that hearScreen® may serve as a an accessible, low-cost, and sensitive pure tone audiometric screen for hearing loss in children at risk, particularly those with conductive hearing loss, with the caveat that it may generate a high proportion of false positives due to the influence of ambient noise, especially when screening at 500 Hz. Future investigations should weigh the utility of including 500 Hz in the screening protocol as well as assess methods that may mitigate the influence of ambient noise during a pure-tone audiometric screen.

Abstract
OBJECTIVES Routines for school hearing screening vary between municipalities in Sweden, and no study has been carried out to investigate how this is conducted throughout the country. The aim of the present study was to determine the extent of school hearing screening, and how it is performed in all the municipalities in Sweden. METHODS An online survey was used to collect information on school hearing screening from municipalities in Sweden (N = 290). The survey included questions on the performance of hearing screening, including stimulus level and frequencies tested, the criteria for referral for further hearing evaluation, as well as the equipment and room used for testing, and who carried out the screening. Questions were also included on experience of, and attitudes towards hearing screening. RESULTS Answers were received from 225 municipalities (response rate 78%). Universal school hearing screening was performed in 202 municipalities, while in the other municipalities hearing screening was performed when a child was evaluated due to speech delay or learning difficulties. Many different protocols were used involving different stimulus levels, frequencies, and referral criteria. The most common was testing with pure tone audiometry with a lowest stimulus level of 20 dB HL at five frequencies, 500-6000 Hz. Hearing screening was usually performed in the preparation class (6 years of age), while in other municipalities it was performed in year 1 (7 years of age). Hearing screening was usually performed once in primary school, while some municipalities carried out screening once in primary school and once in high school. More rarely, hearing screening was conducted twice in primary school. In 25 % of the municipialities, newly arrived immigrant children were screened. Difficulties in performing hearing screening were reported, such as lack of soundproof rooms, lack of time and technical difficulties. There was an opinion among the participants that identifying students with hearing loss is important, as it affects their learning ability and communication skills. and they expressed a desire for national guidelines. CONCLUSIONS Hearing screening is performed in the vast majority of municipally run schools in Sweden. The way in which screening was performed varied regarding the stimulus level and frequencies used, as well as the criteria for referral to a specialist. The attitude towards hearing screening was positive among the participants. Hearing screening of newly immigrated children is important as their previous medical history is often unknown. There is a need for national guidelines on hearing screening of Swedish schoolchildren. Efforts must continue to ensure that the same level of healthcare regarding children's hearing is provided throughout the whole of Sweden.

Abstract
BACKGROUND In low- and middle-income countries (LMICs), where universal newborn hearing screening programmes are often not available, school entry hearing screening programmes serve as a safeguard for early detection and intervention for hearing loss in school learners. OBJECTIVE To determine a contextually appropriate school entry hearing screening protocol for LMICs. METHODS A scoping review was utilised to comprehensively search for relevant publications in the following electronic databases: Africa-Wide Information, CINAHL, Health Source: Nursing/Academic Edition, Cochrane Library, Pubmed, Scopus, and Web of Science. Studies included those that investigated school-based hearing screening protocols or programmes for LMICs among learners aged five to twelve years. The review was conducted and reported according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews checklist. RESULTS The search yielded 1863 studies, and after removing duplicates and ineligible studies, 19 studies were selected for data extraction. Pure tone audiometry screening was the most frequently used age-appropriate hearing screening test in the reviewed studies (n = 17). Conducting pure tone audiometry screening using 1, 2, and 4 kHz frequency combination resulted in referral rates ranging from 3.2% to 21%. In studies that included 0.5 kHz to the screening frequencies, referral rates ranged from 5.8% to 56%. Screening at 25 dB HL intensity level yielded referral rates ranging from 3.2% to 10.3%. Immediate rescreening reduced overall referral rates for learners referred for audiological diagnostic testing by up to 57%. Ambient noise levels were controlled by conducting screening in quiet rooms (n = 14) and utilising screening equipment that allows for monitoring and reducing environmental noise (n = 3). CONCLUSION An ideal school entry hearing screening protocol in LMIC contexts could potentially utilise pure tone audiometry screening at 1, 2, and 4 kHz, using 25 dB HL screening intensity level with an immediate rescreen for learners with a refer result. School entry hearing screening should be conducted in a quiet room, preferably using hearing screening equipment capable of monitoring ambient noise levels to reduce false positive referrals.

Abstract
Purpose The purpose of this study is to describe and assess a hearing screening program of first-grade children in Poland. The program aimed to detect hearing disorders and increase awareness among parents of hearing problems. Method A hearing screening program was conducted in all elementary schools of the biggest region in Poland. A total of 34,618 first-graders were screened. The hearing screening protocol included video otoscopy and pure-tone audiometry. The program also included an information campaign directed to the local community and educational meetings between parents and medical staff. Results The estimated prevalence of hearing loss was 11%. Unilateral hearing loss was more common than bilateral hearing loss. Mild hearing loss was more frequent than moderate (or worse) hearing loss. In otoscopy, the most common positive result was otitis media with effusion. Parents and medical staff took part in 1,608 educational meetings, broadening the parents' knowledge of how to care for hearing. Conclusions A hearing screening program not only provides data on the prevalence of childhood hearing problems but is also an avenue for providing the local community with valuable knowledge about how to care for hearing. This study demonstrated the importance for systematic monitoring of children's hearing status and of increasing awareness among parents and teachers of the significance of hearing loss. The hearing screening of children starting school should become a standard part of school health care programs.

Abstract
Purpose This study aimed to describe and compare the performance of two screening protocols used for preschool hearing screening in resource-constrained settings. Method Secondary data analysis was done to determine the performance of two protocols implemented during a preschool hearing screening program using mobile health technology in South Africa. Pure-tone audiometry screening at 25 dB HL for 1000, 2000, and 4000 Hz in each ear was used by both protocols. The fail criterion for the first protocol (2,147 children screened) constituted a no-response on one or more frequencies in either ear. The second protocol required two or more no-responses (5,782 children). Multivariate logistic regression models were used to investigate associations between outcomes and protocol, age, gender, and duration. Results Fail rates for the one-frequency fail protocol was 8.7% (n = 186) and 4.3% (n = 250) for the two-frequency fail protocol. Children screened with the two-frequency fail protocol were 52.9% less likely to fail (p < .001; OR = 0.471; 95% confidence interval [0.385, 0.575]). Gender (p = .251) and age (p = .570) had no significant effect on screening outcome. A percentage of cases screened (44.7%) exceeded permissible noise levels in at least one ear at 1000 Hz across both protocols. True- and false-positive cases did not differ significantly between protocols. Protocol type (p = .204), gender (p = .314), and age (p = .982) did not affect the odds of being a true-positive result. Average screening time was 72.8 s (78.66 SD) and 64.9 s (55.78 SD) for the one-frequency and two-frequency fail protocols, respectively. Conclusions A two-frequency fail criterion and immediate rescreen of failed frequencies significantly reduced referral rate for follow-up services that are often overburdened in resourced-constrained settings. Future protocol adaptations can also consider increasing the screening levels at 1000 Hz to minimize the influence of environmental noise.

Abstract
Background According to the World Health Organization (WHO), hearing loss (HL) has a significant disease burden with a global prevalence as high a 5% with an expected exponential rise in the coming years. HL has medical, social, and psychological implications on one’s health. A significant proportion of HL cases might be the result of preventable conditions, especially among the young. Aim To estimate the pattern of HL and its correlates among adolescent, adult, and elderly populations in the southern regions of Saudi Arabia. Methodology A retrospective observational study was carried out between May 2018 and April 2019 across four different ENT clinics located across Saudi Arabia. We included all patients who had a clinical diagnosis of conductive, sensorineural, or mixed HL with varying degrees of severity tested via Pure Tone Audiometer (PTA). Results We included 332 cases with HL, ages ranged from 14 to 62 years old with a mean age of 45.2 ±12.6 years. HL was bilateral in 72% of the cases and was associated with tinnitus in 43.1% of cases. Sensorineural HL was the predominant pattern of HL among the elderly and conductive pattern was more common among the young. Causes such as infections, congenital causes, and age-related damage were among the key causes of HL. Conclusion Our study showed that HL might be more prevalent among the Saudi population than previously reported. Sensorineural HL is most common among the elderly. However, conductive HL following ear infections is the main cause of HL among young. Therefore, there is a need for significant improvement in public health surrounding ear health to prevent reversible causes of HL, especially among the young.

Abstract
OBJECTIVES To compare outcomes of a community-based hearing screening programme using smartphone screening audiometry operated by specialist (School Health Nurses - SHNs) and non-specialist health workers (Community Health Workers - CHWs) in school children. DESIGN This study used a two-group comparison of screening outcomes as conducted by SHNs and CHWs using smartphone screening for children in communities. STUDY SAMPLE The study included 71 CHWs and 21 SHNs who conducted community-based hearing screening on 6805 children. One thousand one hundred and fifteen hearing screening tests were conducted by the CHWs and 5690 tests by the SHNs. RESULTS No significant difference in screening outcome was evident between CHWs and SHNs using a binomial logistic regression analysis considering age, test duration and noise levels as independent variables. Final screening result was significantly affected by age (p < 0.005), duration of test (p < 0.005) and noise levels exceeding at 1 kHz in at least one ear (p < 0.005). Test failure was associated with longer test duration (p < 0.005; B: 119.98; 95% CI: 112.65-127.30). CHWs had significantly (p < 0.005) longer test durations (68.70 s; 70 SD) in comparison to SHNs (55.85 s; 66.1 SD). CONCLUSION Low-cost mobile technologies with automated testing facilitated from user-friendly interfaces allow minimally trained persons to provide community-based screening comparable to specialised personnel.

Abstract
Objective To implement and evaluate a community-based hearing and vision screening programme for preschool children in the Western Cape, South Africa, supported by mobile health technology (mHealth) and delivered by community health workers (CHWs). Methods We trained four CHWs to provide dual sensory screening in preschool centres of Khayelitsha and Mitchells Plain during September 2017–December 2018. CHWs screened children aged 4–7 years using mHealth software applications on smartphones. We used logistic regression analysis to evaluate the association between screening results and age, sex and test duration, and, for hearing, excessive background noise levels. Results CHWs screened 94.4% (8023/10 362) of eligible children at 271 centres at a cost of 5.63 United States dollars per child. The number of children who failed an initial hearing and visual test was 435 (5.4%) and 170 (2.1%), respectively. Hearing test failure was associated with longer test times (odds ratio, OR: 1.022; 95% confidence interval, CI: 1.021–1.024) and excessive background noise levels at 1 kilohertz (kHz) (e.g. OR for left ear: 1.688; 95% CI: 1.198–2.377). Visual screening failure was associated with longer test duration (OR: 1.003; 95% CI: 1.002–1.005) and younger age (OR: 0.629; 95% CI: 0.520–0.761). Of the total screened, 111 (1.4%) children were diagnosed with a hearing and/or visual impairment. Conclusion mHealth-supported CHW-delivered hearing and vision screening in preschool centres provided a low-cost, acceptable and accessible service, contributing to lower referral numbers to resource-constrained public health institutions.

Abstract
Background Hearing ability is important for children to develop speech and language skills as they grow. After a mandatory newborn hearing screening, group or mass screening of children at later ages, such as at preschool age, is often practiced. For this practice to be effective and accessible in low-resource countries such as Thailand, innovative enabling tools that make use of pervasive mobile and smartphone technology should be considered. Objective This study aims to develop a cost-effective, tablet-based hearing screening system that can perform a rapid minimal speech recognition level test. Methods An Android-based screening app was developed. The screening protocol involved asking children to choose pictures corresponding to a set of predefined words heard at various sound levels offered in a specifically designed sequence. For the app, the set of words was validated, and their corresponding speech power levels were calibrated. We recruited 122 children, aged 4-5 years, during the development phase. Another 63 children of the same age were screened for their hearing abilities using the app in version 2. The results in terms of the sensitivity and specificity were compared with those measured using the conventional audiometric equipment. Results For screening purposes, the sensitivity of the developed screening system version 2 was 76.67% (95% CI 59.07-88.21), and the specificity was 95.83% (95% CI 89.77-98.37) for screening children with mild hearing loss (pure-tone average threshold at 1, 2, and 4 kHz, >20 dB). The time taken for the screening of each child was 150.52 (SD 19.07) seconds (95% CI 145.71-155.32 seconds). The average time used for conventional play audiometry was 11.79 (SD 3.66) minutes (95% CI 10.85-12.71 minutes). Conclusions This study shows the potential use of a tablet-based system for rapid and mobile hearing screening. The system was shown to have good overall sensitivity and specificity. Overall, the idea can be easily adopted for systems based on other languages.

Abstract
Background: Hearing loss is one of the most common developmental disorders identifiable at birth with its prevalence increasing throughout school years. However, early detection programs are mostly unavailable in low- and middle-income countries (LMICs) where more than 80% of children with hearing loss reside. Objective: This study investigated the feasibility of a smartphone-based hearing screening program for preschool children operated by community healthcare workers (CHWs) in community-based early childhood development (ECD) centers. Method: Five CHWs were trained to map ECD centers and conduct smartphone-based hearing screenings within a poor community in South Africa over a 12-month period. The hearScreenTM smartphone application employed automated test protocols operating on low-cost smartphones. A cloud-based data management and referral function allowed for remote monitoring for surveillance and follow up. Results: 6424 children (3–6 years) were screened for hearing loss with an overall referral rate of 24.9%. Only 39.4% of these children attended their follow-up appointment at a local clinic, of whom 40.5% referred on their second screening. Logistic regression analysis indicated that age, gender and environmental noise levels (1 kHz) had a significant effect on referral rates (p < 0.05). The quality index reflecting test operator test quality increased during the first few months of testing. Conclusion: Smartphone-based hearing screening can be used by CHWs to detect unidentified children affected by hearing loss within ECD centers. Active noise monitoring, quality indices of test operators and cloud-based data management and referral features of the hearScreenTM application allows for the asynchronous management of hearing screenings and follow-ups.

Abstract
Background Asynchronous automated telehealth-based hearing screening and diagnostic testing can be used within the rural school context to identify and confirm hearing loss. Objective The aims of the study were to evaluate the efficacy of an asynchronous telehealth-based service delivery model using automated technology for screening and diagnostic testing as well as to describe the prevalence, type and degree of hearing loss. Method A comparative within-subject design was used. Frequency distributions, sensitivity, specificity scores as well as the positive and negative predictive values were calculated. Testing was conducted in a non-sound-treated classroom within a school environment on 73 participants (146 ears). The sensitivity and specificity rates were 65.2% and 100%, respectively. Diagnostic accuracy was 91.7% and the negative predictive values (NPV) and positive predictive values (PPV) were 93.8% and 100%, respectively. Results Results revealed that 23 ears of 20 participants (16%) presented with hearing loss. Twelve per cent of ears presented with unilateral hearing impairment and 4% with bilateral hearing loss. Mild hearing loss was identified as most prevalent (8% of ears). Eight ears obtained false-negative results and presented with mild low- to mid-frequency hearing loss. The sensitivity rate for the study was low and was attributed to plausible reasons relating to test accuracy, child-related variables and mild low-frequency sensory-neural hearing loss. Conclusion The study demonstrates that asynchronous telehealth-based automated hearing testing within the school context can be used to facilitate early identification of hearing loss; however, further research and development into protocol formulation, ongoing device monitoring and facilitator training is required to improve test sensitivity and ensure accuracy of results.

Abstract
OBJECTIVES As the various regional authorities responsible for health care in Sweden operate independently, no knowledge was available on pre-school hearing screening available to children living in different parts of the country. The aim of this study was to carry out a survey to ascertain how preschool hearing screening was performed in the various regions of Sweden. An objective of the present paper was also to present the uniform national guidelines for pre-school hearing screening that were launched by health authorities and were based on this study. A follow-up investigation was performed to ascertain whether the new guidelines were well accepted and followed throughout the country. METHODS A questionnaire was sent to 25 physicians responsible for child health care centers in all 21 regions throughout the whole country. The questionnaire included detailed questions on hearing screening in preschool children. New national guidelines were introduced in cooperation with health authorities and providers of preventive child health care. After two and four years, questionnaires were sent to the same recipients to determine whether changes in practice in pre-school hearing screening had been implemented, and to obtain information about experiences with the new guidelines. RESULTS Sixteen of 21 regions practiced universal hearing screening of 4-yearolds. Many different protocols were used. Professionals at child health care centers expressed a need for national guidelines for pre-school hearing screening. At the two and four-year follow-ups, one more region had introduced universal hearing screening of 4-year-olds, while two regions were planning to introduce it in 2019. The new national guidelines were well accepted and used throughout the country. CONCLUSION There was a great variability in how pre-school hearing screening was performed in Sweden. Efforts are being made to provide uniform pre-school hearing screening. Cooperation between professionals in hearing health and health authorities is needed in order to broaden the use of universal pre-school hearing screening and to implement the new national guidelines.

Abstract
Supplemental Digital Content is available in the text. Objectives: There are no nationally representative hearing loss (HL) prevalence data available for Canadian youth using direct measurements. The present study objectives were to estimate national prevalence of HL using audiometric pure-tone thresholds (0.5 to 8 kHz) and or distortion product otoacoustic emissions (DPOAEs) for children and adolescents, aged 3 to 19 years. Design: This cross-sectional population-based study presents findings from the 2012/2013 Canadian Health Measures Survey, entailing an in-person household interview and hearing measurements conducted in a mobile examination clinic. The initial study sample included 2591 participants, aged 3 to 19 years, representing 6.5 million Canadians (3.3 million males). After exclusions, subsamples consisted of 2434 participants, aged 3 to 19 years and 1879 participants, aged 6 to 19 years, with valid audiometric results. Eligible participants underwent otoscopic examination, tympanometry, DPOAE, and audiometry. HL was defined as a pure-tone average >20 dB for 6- to 18-year olds and ≥26 dB for 19-year olds, for one or more of the following: four-frequency (0.5, 1, 2, and 4 kHz) pure-tone average, high-frequency (3, 4, 6, and 8 kHz) pure-tone average, and low-frequency (0.5, 1, and 2 kHz) pure-tone average. Mild HL was defined as >20 to 40 dB (6- to 18-year olds) and ≥26 to 40 dB (19-year olds). Moderate or worse HL was defined as >40 dB (6- to 19-year olds). HL in 3- to 5-year olds (n = 555) was defined as absent DPOAEs as audiometry was not conducted. Self-reported HL was evaluated using the Health Utilities Index Mark 3 hearing questions. Results: The primary study outcome indicates that 7.7% of Canadian youth, aged 6 to 19, had any HL, for one or more pure-tone average. Four-frequency pure-tone average and high-frequency pure-tone average HL prevalence was 4.7 and 6.0%, respectively, whereas 5.8% had a low-frequency pure-tone average HL. Significantly more children/adolescents had unilateral HL. Mild HL was significantly more common than moderate or worse HL for each pure-tone average. Among Canadians, aged 6 to 19, less than 2.2% had sensorineural HL. Among Canadians, aged 3 to 19, less than 3.5% had conductive HL. Absent DPOAEs were found in 7.1E% of 3- to 5-year olds, and in 3.4E% of 6- to 19-year olds. Among participants eligible for the hearing evaluation and excluding missing data cases (n = 2575), 17.0% had excessive or impacted pus/wax in one or both ears. Self-reported HL in Canadians, aged 6 to 19, was 0.6 E% and 65.3% (aged 3 to 19) reported never having had their hearing tested. E indicates that a high sampling variability is associated with the estimate (coefficient of variation between 16.6% and 33.3%) and should be interpreted with caution. Conclusions: This study provides the first estimates of audiometrically measured HL prevalence among Canadian children and adolescents. A larger proportion of youth have measured HL than was previously reported using self-report surveys, indicating that screening using self-report or proxy may not be effective in identifying individuals with mild HL. Results may underestimate the true prevalence of HL due to the large number excluded and the presentation of impacted or excessive earwax or pus, precluding an accurate or complete hearing evaluation. The majority of 3- to 5-year olds with absent DPOAEs likely had conductive HL. Nonetheless, this type of HL which can be asymptomatic, may become permanent if left untreated. Future research will benefit from analyses, which includes the slight HL category, for which there is growing support, and from studies that identify factors contributing to HL in this population.

Abstract
Introduction Access to ear and hearing health is a challenge in developing countries, where the burden of disabling hearing loss is greatest. This study investigated community-based identification of hearing loss using smartphone hearing screening (hearScreen™) operated by community health workers (CHWs) in terms of clinical efficacy and the reported experiences of CHWs. Method The study comprised two phases. During phase one, 24 CHWs performed community-based hearing screening as part of their regular home visits over 12 weeks in an underserved community, using automated test protocols employed by the hearScreen™ smartphone application, operating on low-cost smartphones with calibrated headphones. During phase two, CHWs completed a questionnaire regarding their perceptions and experiences of the community-based screening programme. Results Data analysis was conducted on the results of 108 children (2–15 years) and 598 adults (16–85 years). Referral rates for children and adults were 12% and 6.5% respectively. Noise exceeding permissible levels had a significant effect on screen results at 25 dB at 1 kHz ( p<0.05). Age significantly affected adult referral rates ( p < 0.05), demonstrating a lower rate (4.3%) in younger as opposed to older adults (13.2%). CHWs were positive regarding the hearScreen™ solution in terms of usability, need for services, value to community members and time efficiency. Conclusion Smartphone-based hearing screening allows CHWs to bring hearing health care to underserved communities at a primary care level. Active noise monitoring and data management features allow for quality control and remote monitoring for surveillance and follow-up.
