Abstract
INTRODUCTION This study aimed to validate three age-adjusted versions of a Hearing Screening Questionnaire for Preschoolers, in Brazilian Portuguese, based on parents' perception of their children's hearing and oral language. METHODS Psychometric validation was conducted on three questionnaires, each comprising nine items with yes/no responses. Three items focused on hearing screening at birth, and six assessed hearing and oral language. The study included 152 parents and their children, who attended daycare centers in Belo Horizonte, Brazil. The children were categorized into three age bands: 12-18 months, 19-35 months, and 36-48 months. Audiological assessments, including tympanometry, transient-evoked otoacoustic emissions (TEOAE), and pure-tone audiometry (when applicable), were performed on the children. In case of abnormal findings in the previous exams, auditory brainstem response (ABR) testing was conducted. Descriptive data, false alarm, and false-negative analyses were carried out. RESULTS Considering any type of hearing loss, whether unilateral or bilateral, the questionnaires showed a false-negative rate of 41.17% (7/17 children). However, when considering only bilateral hearing loss, the questionnaire showed a false alarm rate of 31.69% (45/142) and a false-negative rate of 30.0% (3/10). When focusing exclusively on sensorineural hearing loss, the questionnaire identified two children (1.31%), with a false-negative rate of 0% but a false-positive rate of 33.33%. CONCLUSION Language-development-oriented questionnaires allowed quick screening of potential hearing loss in preschoolers. This study found a robust hit rate with these questionnaires. Their validation signifies a promising and cost-effective tool for conducting hearing screenings in preschool children, especially in nations lacking a comprehensive school screening policy. The validated questionnaire affords an easy-to-apply, low-cost, and effective instrument for preschool hearing screening.

[PMID: 37992622 DOI: 10.1016/j.ijporl.2023.111785] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/19/2023] [Revised: 10/31/2023] [Accepted: 11/09/2023] [Indexed: 11/24/2023]
Abstract
OBJECTIVES This study estimated the permanent hearing loss (PHL) prevalence among newborns and 6-year-olds in the Uppsala region (Sweden), compared how different definitions affected this estimation, and evaluated the outcome of the three hearing screening occasions for children. METHODS A retrospective investigation of medical records and audiograms was conducted for children born in 2011-2012. Data extraction was performed when the children had reached 7 years of age. Hearing loss was defined as > 20 dB hearing level in at least one frequency (125-8000 Hz) in one or both ears (clinician's definition). RESULTS A total of 1385 children were included, and 95 were diagnosed with PHL. The prevalence of bilateral PHL at 6 years was 5.50 per 1000 children based on the clinician's definition, 3.74 per 1000 children based on the World Health Organization (WHO) 2021 definition, and 2.64 per 1000 children based on the WHO 1991 definition. Adding unilateral PHL resulted in a total prevalence of 10.11 (clinician's definition) and 6.16 (WHO 2021) per 1000 children. CONCLUSION This study demonstrates the necessity of repeated hearing testing during childhood to identify PHL and suggests a higher prevalence in 6-year-olds than previously reported. The definition of PHL greatly impacted its estimated prevalence.

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
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
AIM We aimed to estimate the risk of hearing impairment in children and adolescents with foreign-born parents, compared to natives. METHODS A nationwide study of 1,923,590 (51.4% boys) individuals aged 0-17 years of age in Sweden. Hearing impairment was defined as at least one registered diagnosis in the National Patient Register between 1 January 1998 and 31 December 2015. We used Cox regression analysis to estimate relative risk (hazard ratios with 99% confidence intervals) of incident hearing impairment in children with foreign-born parents compared to Swedish-born natives. Cox regression models were stratified by sex and adjusted for age, co-morbidities and socioeconomic status. RESULTS A total of 20,514 cases (53.7% boys) with extended sensorineural hearing impairment were registered, also including noise-induced hearing impairment and that from other causes, and 6172 cases (50.0% boys) with conductive hearing impairment. The risk of extended sensorineural hearing impairment was higher in boys with parents from Asia, especially from Iraq, fully adjusted HR (99% CI) 1.30 (1.17-1.4), and lower in boys with parents from Nordic countries, South Europe, and North America. CONCLUSION The risk of extended sensorineural hearing impairment was higher in boys with parents from Asia, in particular Iraq.

Abstract
AIM The risk for language disorder is high in children with all levels of hearing loss (HL). Early identification and intervention should be as important for children with mild HL as for those with more severe HL. Despite new-born hearing screening, a recent survey of speech language therapist services in southern Sweden indicates that children with mild and moderate HL are severely neglected when it comes to language assessment and language intervention. In this study we explore associations between Best Ear Hearing Level (BEHL), time factors and language skills in Swedish children with HL with hearing aids (HA). METHOD Participants were 19 children with mild HL (BEHL 23-39) and 22 children with moderate HL (BEHL 40-70) aged 5-15 years. Information on age at diagnosis and at HA fitting were collected. The children performed a nonword repetition and a sentence comprehension task. RESULTS The time elapsed between diagnosis and fitting with HA was longer for the children with mild HL.Participants with mild HL received their HA significantly later than children with moderate HL. No association between BEHL and the two language measures was found, and language skills were not better in children with mild than moderate HL. 17% of participants performed below cut-off for language disorder on both language measures. CONCLUSION Given the risk for long-term academic and social consequences of even mild HL delayed HA intervention for children with HLleads to serious concerns by families, clinicians, and pedagogues.

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
Hearing impairment is the most common sensory impairment that is seen among adults and children. The frequency of congenital hearing loss is well-known due to implementation of newborn hearing screening. Hearing may change throughout a lifetime due to different factors and, therefore, the number of hearing impaired children increases with age. Introduction of universal newborn hearing screening has enabled earlier detection of hearing loss including unilateral and minimal disorders. Nevertheless, despite significant progress made in this field, there is still a group of hearing impairments that stay undiagnosed timely. Auditory neuropathy spectrum disorders, late-onset hearing loss, low-frequency and minimal hearing impairment are sometimes missed in newborn hearing screening or they manifest later. These types of hearing disorders are covered in detail in this review as well as possible ways of increasing the effectiveness of early diagnosis.

Abstract
Introduction Globally, more than 50 million children have hearing or vision loss. Most of these sensory losses are identified late due to a lack of systematic screening, making treatment and rehabilitation less effective. Mobile health (mHealth), which is the use of smartphones or wireless devices in health care, can improve access to screening services. mHealth technologies allow lay health workers (LHWs) to provide hearing and vision screening in communities. Purpose The aim of the study was to evaluate a hearing and vision school screening program facilitated by LHWs using smartphone applications in a low-income community in South Africa. Method Three LHWs were trained to provide dual sensory screening using smartphone-based applications. The hearScreen app with calibrated headphones was used to conduct screening audiometry, and the Peek Acuity app was used for visual acuity screening. Schools were selected from low-income communities (Gauteng, South Africa), and children aged between 4 and 9 years received hearing and vision screening. Screening outcomes, associated variables, and program costs were evaluated. Results A total of 4,888 and 4,933 participants received hearing and vision screening, respectively. Overall, 1.6% of participants failed the hearing screening, and 3.6% failed visual acuity screening. Logistic regression showed that female participants were more likely to pass hearing screening (OR = 1.61, 95% CI [1.11, 2.54]), while older children were less likely to pass visual acuity screening (OR = 0.87, 95% CI [0.79, 0.96]). A third (32.5%) of referred cases followed up for air-conduction threshold audiometry, and one in four (25.1%) followed up for diagnostic vision testing. A high proportion of these cases were confirmed to have hearing (73.1%, 19/26) or vision loss (57.8%, 26/45). Conclusions mHealth technologies can enable LHWs to identify school-age children with hearing and/or vision loss in low-income communities. This approach allows for low-cost, scalable models for early detection of sensory losses that can affect academic performance.

Changes in auditory function in premature children: A prospective cohort study. Int J Pediatr Otorhinolaryngol 2020; 139:110456.

Abstract
OBJECTIVES To analyze the age-specific pattern of auditory function in preterm children as a function of their gestational age at birth. STUDY DESIGN longitudinal cohort study. METHODS a prospective cohort study involved 271 preterm children aged from 6 months to 15 years old. Children were divided into two groups: 70 children with a gestational age at birth of 32-36 weeks (Group 1) and 201 children with a gestational age of 22-31 weeks (Group 2). Hearing was assessed by ABR, ASSR, OAE, behavioral audiometry, and pure tone audiometry. Additionally, for some children, CT, MRI, and GBJ2 evaluations were performed. Assessments of hearing impaired children were performed 3-4 times a year for children under 2 years of age; 2-3 times a year for children from 2 to 5 years of age; and 1-2 times a year for children over 5 years of age. Infants without any hearing problems were examined 2-3 times during their first year of life, followed by annual examinations as they aged. RESULTS The initial hearing examination identified SNHL and ANSD in 18 children (25.7%) and 64 children (31.8%) in Group 1 and Group 2, respectively. No significant difference in the occurrence of auditory impairment in the two groups was found at the initial assessment (p > 0.05). Further long-term follow-up revealed changes in hearing in 16 children: 15 from Group 2 and only one child from Group 1. Four different kinds of hearing changes were noted: hearing recovery to normal levels in children with ANSD; late onset hearing loss; the transformation of ANSD to SNHL, and vice versa. The age, factors, and possible mechanisms of such changes are discussed in the article. CONCLUSION The auditory function in prematurely born children tends to be unstable, especially at a very early age. In very preterm infants, it may either deteriorate or improve. Infants born before 31 weeks' gestation require long-term follow-up at least until they are 3-4 years of age. Caution is advised regarding very early cochlear implantation for children born before 32 weeks of gestation age.

Abstract
Objective School hearing screening may mitigate the effects of childhood hearing loss through early identification and intervention. This study provides an overview of existing school hearing screening programs around the world, identifies gaps in the literature, and develops priorities for future research. Data Sources A structured search of the PubMed, Embase, and Cochrane Library databases. Review Methods A total of 65 articles were included according to predefined inclusion criteria. Parameters of interest included age groups screened, audiometric protocols, referral criteria, use of adjunct screening tests, rescreening procedures, hearing loss prevalence, screening test sensitivity and specificity, and loss to follow-up. Conclusions School hearing screening is mandated in few regions worldwide, and there is little accountability regarding whether testing is performed. Screening protocols differ in terms of screening tests included and thresholds used. The most common protocols included a mix of pure tone screening (0.5, 1, 2, and 4 kHz), otoscopy, and tympanometry. Estimates of region-specific disease prevalence were methodologically inaccurate, and rescreening was poorly addressed. Loss to follow-up was also a ubiquitous concern. Implications for Practice There is an urgent need for standardized school hearing screening protocol guidelines globally, which will facilitate more accurate studies of hearing loss prevalence and determination of screening test sensitivity and specificity. In turn, these steps will increase the robustness with which we can study the effects of screening and treatment interventions, and they will support the development of guidelines on the screening, diagnostic, and rehabilitation services needed to reduce the impact of childhood hearing loss.
