Factors associated with allergic rhinitis and combined allergic rhinitis and asthma syndrome (CARAS) in adults undergoing immunotherapy in a tropical country: Is ISAAC-III questionnaire useful in adult populations?

BACKGROUND: Allergic diseases affect about 10-30% of the population in low- or middle-income tropical countries. Few studies describe the factors associated with allergic diseases in adult patients undergoing immunotherapy in Latin American countries. OBJECTIVE: This study aimed to determine the factors associated with allergic rhinitis (AR) and AR in comorbidity with asthma (CARAS) in adults treated with immunotherapy in two allergy referral centers in Bogotá (Colombia). MATERIAL AND METHODS: Observational, cross-sectional study conducted between January 2018 and January 2019. ISAAC-III and sociodemographic questionnaires were applied to determine the factors associated with AR and CARAS in adults treated with immunotherapy who attended the allergy consult at the Fundación Santa Fe de Bogotá and Unimeq-Orl. RESULTS: Among 416 adults aged 18-68 years, 71.4% (n = 297) were women. Regarding the sensitization results obtained by skin prick test, the most frequent allergens were house dust mites (64.18%): 49.03% were positive for both Dermatophagoides pteronyssinus and Dermatophagoides farinae, while 28.61% were positive for Blomia tropicalis. Excluding house dust mites, the most frequent allergens were dog hair (31.01%), cat hair (15.1%), grasses (15.9%), and food (15.9%). The main factor associated with exclusive AR was regular acetaminophen use more than four times a year: Prevalence ratio (PR) = 1.77 (95% CI: 1.12-2.25). The main factor associated with CARAS was cesarean delivery PR: 1.44 (95% CI: 1.09-1.78). CONCLUSION: The main factor associated with AR was regular acetaminophen use, while that associated with CARAS was cesarean delivery. The ISAAC-III questionnaire can be a useful low-cost tool to assess the factors associated with allergic diseases in adults in tropical countries.

Audiological benefit, quality of life, and factors associated with functional gain in elderly hearing aid users in a developing country between 2017 and 2020: a pre-post-study.

BACKGROUND: Sensorineural hearing loss (SNHL) is the most common auditory deficit in older adults and may lead to quality-of-life deterioration. However, few studies have been performed in low/middle-income countries, particularly in Latin America. This study aimed to assess the audiological benefit, quality of life, and factors associated with functional gain in elderly hearing aid users in the Fundación Santa Fe de Bogotá and UNIMEQ-ORL, two otology referral centers in Colombia. DESIGN: Pre-post study that included hearing aid users at the otology consult of the Fundación Santa Fe de Bogotá and UNIMEQ-ORL between June 2017 and December 2020. Glasgow Benefit Inventory (GBI) and Abbreviated Profile of Hearing Aid Benefit (APHAB) questionnaires were applied. Audiometric (0,5 kHz to 4 kHz) and speech audiometry results were collected. RESULTS: A total of 75 participants (132 ears) were included. The mean age was 70.73 years (SD: 12.66). The median hearing aid use in years was 0.71 (IQR: 0.64-0.90). Mean change in speech audiometry was - 26.53dB (95%CI: -28.09, -24.97; p < 0.001), in functional gain was - 21.75dB (-23.81, -19.68; p < 0.001). The mean changes in the APHAB domains were Ease of Communication: -37.85 (95%CI: -43.01; -32.7), Background Noise: -3.51 (-6.06; -0.95), and Aversiveness of Sounds: -6.9 (-2.04; 11.77). The GBI assessment of quality of life showed improvement in 100% of the population after the use of hearing aids. The number of years of hearing aids use was associated with functional gain. CONCLUSION: The number of years of hearing aids use may impact on the functional gain in these populations. A significant clinical benefit was found in terms of quality of life, communication, and reverberation related to the use of hearing aids. Access to hearing aids should be granted, and public health strategies are needed to grant the access to hearing rehabilitation in these populations.

Dizziness in adults with chronic otitis media at two otology referral centres in Colombia: a cross-sectional study in a middle-income country.

OBJECTIVE: This study aimed to determine the prevalence of dizziness and its associated factors in patients with COM at two otologic referral centres in a middle-income country. DESIGN: Cross-sectional study. Adults with and without COM diagnosis from two otology-referral centres in Bogotá (Colombia) were included. Dizziness and quality of life were assessed using the "Chronic Suppurative Otitis Media Questionnaire-12" (COMQ-12), and sociodemographic questionnaires were applied. Otoscopic evaluation and audiometric data were collected. STUDY SAMPLE: A total of 231 adults. RESULTS: Of the 231 participants, up to 64.5% (n = 149) reported at least mild inconvenience due to dizziness. Factors associated with dizziness included female sex (aPR: 1.23; 95% CI: 1.04-1.46), chronic suppurative otitis media (aPR: 3.02; 95% CI: 1.21-7.52), and severe tinnitus (aPR: 1.75; 95% CI: 1.24-2.48). An interaction was found between socioeconomic status and educational level, with more frequent reports of dizziness in the middle/high economic status and secondary education (aPR: 3.09; 95% CI: 0.52-18.55; p < 0.001). Differences of 14 points in symptom severity and 18.5 points in the total score of the COMQ-12 were found between the groups with dizziness and without dizziness. CONCLUSIONS: Dizziness was frequent in patients with COM and was associated with severe tinnitus and quality of life deterioration.

Factors associated with allergic rhinitis and combined allergic rhinitis and asthma syndrome (CARAS) in children aged 5-18 years undergoing immunotherapy in a tropical low- or middle-income country.

BACKGROUND: Tropics have some particularities that can impact the natural history and factors associated with allergic diseases. However, few studies described the characteristics of patients with allergic rhinitis (AR) and combined AR and asthma syndrome (CARAS) in Latin American tropical countries. OBJECTIVE: This study aimed to determine the medical, social, and environmental factors associated with AR and CARAS in children aged 5-18 years treated with immunotherapy in two allergy referral centers in Bogotá (Colombia). MATERIAL: and methods: An observational, cross-sectional study was conducted between January 2018 and January 2019. International Study Asthma Allergies Childhood-III and sociodemographic questionnaires were applied to adolescents and parents of children undergoing immunotherapy at the allergy consult in the Hospital Universitario Fundación Santa Fe de Bogotá and UNIMEQ-ORL. RESULTS: Among 830 children aged 5-18 years, 38.1% (n = 316) were women. Up to 63.25% of the population had a positive skin prick test for house dust mites: 63.25% for Dermatophagoides pteronyssinus, 61.81% for Dermatophagoides farinae, and 31.57% for Blomia tropicalis. The factors associated with AR were male sex (PR: 1.31, 95% CI: 1.08-1.57), antibiotic consumption during the first year of life (PR: 0.80; 95% CI: 0.63-0.99), and exposure to dogs (PR: 1.32; 95% CI: 1.06-2.66). The factors associated with CARAS were older age (PR=0.95; 95% CI: 0.95-0.99), acetaminophen consumption over four times a year (PR: 1.31; 95% CI: 1.03-1.55), and antibiotic consumption during the first year of life (PR: 1.21; 95% CI: 1.06-1.34). CONCLUSION: A high prevalence of B. tropicalis was found in this study. The factors associated with AR and CARAS are like those described in high-income tropical countries. Further studies are needed in low- or middle-income tropical countries to identify modifiable factors associated with allergic diseases.

Analysis of tinnitus severity and associated factors in patients with chronic otitis media in a low- to middle-income country.

OBJECTIVE: This study aimed to describe the tinnitus severity in patients with chronic otitis media (COM) and describe the sociodemographic and clinical variables associated with tinnitus severity. DESIGN: Cross-sectional study. Two otology-referral centers in Bogotá (Colombia) were included. Sociodemographic, clinical associated factors and quality of life questionnaires were applied. Otoscopic evaluation and audiometric data were collected. STUDY SAMPLE: About 231 adults with COM. RESULTS: Up to 51.5% of the patients reported severe tinnitus discomfort, 21.7% moderate discomfort, and 26.8% minor discomfort. Factor associated with increased tinnitus severity in patients with COM were older age (aOR: 1.02; 95% CI: 1.01-1.05), higher education (aOR: 2.24; 95% CI: 1.03-4.87), ear discharge during childhood (aOR: 1.88; 95% CI: 1.02-3.45), cholesteatoma in one ear (aOR: 2.26; 95% CI: 1.05-4.88), and pure-tone air average over 15 dB (aOR: 2.08; 95% CI: 1.28-3.36). Differences of 10-points in symptoms severity and 15-points in the total score of the "Chronic Suppurative Otitis Media Questionnaire-12" were found between the tinnitus severity groups. CONCLUSIONS: Our results highlight the need for further research on the associated factors of tinnitus severity on COM patients. COM patients with higher tinnitus severity presented worse audiometric results and worse quality of life outcomes.

Effect of the COVID-19 pandemic on the mental health, daily and occupational activities of pediatric otolaryngologists in Latin America.

Background: Otolaryngologists have a higher risk of physical/psychological problems due to their frequent exposure to SARS-CoV-2. There is no information about the impact of COVID-19 on the mental health of these specialists in low/middle-income countries from Latin America. This study aimed to assess the frequency of anxiety, depression, and stress, as well as the changes in occupational and daily activities due to the COVID-19 pandemic in a group of pediatric otolaryngologists in Latin America. Methods: Observational, cross-sectional study conducted between October and December 2020. Mental health tools such as the Generalized Anxiety Disorder-7, the Patient Health Questionnaire-9, and the Perceived Stress Scale-10 were applied. Fear to COVID-19 scale and questionnaires about occupational and daily activities were also applied. Results: Among 55 pediatric otolaryngologists, the frequency of anxiety, depression, and stress were 67.3%, 45.5, and 40%, respectively. Up to 27.3% of the specialists reported moderate to severe symptoms of anxiety, while 7.3 and 40% presented moderate depression and stress symptoms. The specialists reported a reduction of 58.3% of their consultations, as well as a 51.7% reduction in their monthly income compared to the same period before the pandemic. Up to 14.6% of the specialists expect to incorporate long-term (>1 year) drastic changes in their daily activities due to the pandemic. Conclusions: The frequency of anxiety, depression, and stress was high among pediatric otolaryngologists in Latin America compared to previous studies performed in high-income countries. Further research on these psychological outcomes is needed to achieve early mental health strategies.

Effect of the COVID-19 pandemic on the mental health, daily and occupational activities among health professionals in Colombia: a national study.

BACKGROUND: The COVID-19 pandemic has placed an unprecedented physical and mental burden on healthcare workers who are frequently at high risk of infection, particularly in low-income countries. This study aimed to assess the prevalence and associated factors of anxiety, depression, and stress, as well as changes in daily and occupational activities among healthcare professionals due to the COVID-19 pandemic in Colombia. METHODS: An observational, cross-sectional study was conducted between February and June 2021. The survey incorporated validated mental health tools such as the Generalized Anxiety Disorder-7, the Patient Health Questionnaire-9, and the Perceived Stress Scale-10. Multivariable ordinal logistic regression analysis was performed to determine the factors associated with severe mental health outcomes. RESULTS: Among 1345 healthcare workers the prevalence of anxiety, depression, and stress were 75.61, 59.18, and 53.09%, respectively. Anxiety (OR:1.44; 95%CI:1.16-1.8), depression (OR:1.74; 95%CI:1.27-2.37), and stress (OR:1.51; 95%CI:1.18-1.94) were more frequent in women, and individuals who expressed fear of a negative outcome (death, sequelae) (OR:2.25; 95%CI:1.60-3.25), (OR:1.49; 95%CI:1.03-2.16) and (OR:2.36; 95%CI:1.69-3.29) respectively. Age was negatively associated with anxiety (OR:0.98; 95%CI:0.98-0.99), stress (OR:0.98; 95%CI:0.97-0.99), and depression (OR:0.97; 95% CI:0.96-0.98). Reduction in consultations and surgeries (OR:1.01; 95%CI:1.0-1.01) was positively associated with anxiety. Due to the pandemic, most specialists expected to incorporate drastic long-term (> 1 year) changes in their clinical setting and daily activities. CONCLUSIONS: The prevalence of anxiety, depression, and stress is higher among Colombian healthcare workers compared to previous reports. Further research regarding these psychological outcomes is needed to achieve early mental health intervention strategies.

Isolated facial palsy after Chikungunya infection: A novel differential diagnosis / Parálisis facial aislada posterior a infección por virus de chikunguña: un nuevo diagnóstico diferencial.

A significant raise in the reports of neurological manifestations due to Chikungunya virus has been described worldwide. Here, we describe a case report of a previously healthy young adult who developed isolated left facial palsy after a confirmed Chikungunya virus infection in the Colombian tropics. We suggest considering this virus as a differential diagnosis for facial palsy in patients with confirmed Chikungunya virus infection who live in endemic regions or report a history of recent travel to these regions.

En las últimas décadas, se ha incrementado el reporte de manifestaciones neurológicas asociadas con la infección por el virus de chikunguña. Se informa el caso de un adulto joven previamente sano que presentó parálisis facial izquierda aislada después de una infección reciente por el virus de chikunguña en el trópico colombiano. Se describen aspectos importantes de la fisiopatología del virus y su tropismo por el sistema nervioso central y periférico, y se sugiere considerar este virus en el diagnóstico diferencial de la parálisis facial en pacientes con infección confirmada por el virus de chikunguña en regiones tropicales endémicas o en aquellos con antecedente de viajes recientes a dichas regiones.

Impact of the COVID-19 national lockdown in the allergic rhinitis symptoms in patients treated with immunotherapy at two allergy referral centers in Bogotá, Colombia.

Background: Coronavirus disease-19 (COVID-19) "lockdowns" caused an abruptly restricted access to health care services such as immunotherapy for allergic rhinitis (AR) and led to higher exposure to indoor allergens. This study aimed to assess the impact of COVID-19 lockdowns on AR symptoms reported by the patients treated with immunotherapy who attended the Hospital Fundación Santa Fe de Bogotá and Unidad Médico Quirúrgica de Otorrinolaringología, Colombia. Methods: Pre-post study that included patients with AR confirmed diagnosis (prick test), treated with immunotherapy before and after COVID-19 lockdowns on March-June 2020. Visual analog scales (VAS) and sociodemographic questionnaires were applied to assess AR symptoms (nasal obstruction, pruritus, rhinorrhea, and ocular symptoms) and their associated factors. Results: A total of 318 participants were included, and their mean age was 18.9 years (SD: 12.8). The median number of immunotherapy doses applied before isolation was 11 (interquartile range [IQR]: 6-19), and the median number of immunotherapy doses missed during isolation was three doses (IQR: 2-3). Up to 38.4% of the AR patients reported that their symptoms got worse during lockdowns. A pre-post mean difference in the VAS score of 0.5 was found for nasal obstruction (p = .01), 0.7 for pruritus (p < .001), 0.7 points for rhinorrhea (p < .001), and 0.8 for ocular symptoms (p < .001). Factors associated with worsening of AR symptom scores were pet ownership, atopic dermatitis, lower educational level, and a low number of immunotherapy doses applied before lockdowns. Conclusion: A large proportion of patients reported worsening of their AR symptoms, probably due to higher exposure to indoor AR allergens and interruption of immunotherapy during COVID-19 lockdowns.

Recurrent Primary Inverted Papilloma of the Mastoid with Intracranial Invasion: A 7-Year Follow-Up.

A 55-year-old man presented to the otolaryngology department complaining of aural fullness in his left ear after an episode of probable otitis 3 months before. magnetic resonance imaging revealed a soft tissue mass within the mastoid cavity that had destroyed the posterior wall of the middle ear with no apparent middle ear or sinonasal origin. The patient underwent a left canal wall-up tympanomastoidectomy, and the pathology report confirmed an inverted papilloma. Inverted papillomas are uncommon benign epithelial tumors related to a high recurrence rate and high risk of secondary malignant transformation after multiple surgeries. The patient has undergone 2 additional surgical interventions involving the neurosurgery team due to recurrent inverted papilloma that exerted a mass effect over the left cerebellar hemisphere. Despite no signs of recurrence on magnetic resonance imaging 5 years after the last surgery, at least 1 radiologic study per year is granted. Clinical multidisciplinary follow-up including nasal endoscopy and head and neck examination as a part of a stringent follow-up is essential to rule out synchronous nasosinusal inverted papillomas.

Síntomas otorrinolaringológicos asociados con infección positiva de SARS-CoV-2 confirmada con RT-PCR: un estudio de casos y controles en Colombia / Otolaryngological symptoms associated with positive RT-PCR SARS-CoV-2 infection: a case-control study in Colombia

Introducción: las alteraciones otorrinolaringológicas en pacientes con COVID-19 tienen particular importancia a nivel mundial. Sin embargo, todavía no hay consenso en la literatura acerca de la epidemiología, la gravedad y el tiempo de recuperación de estos trastornos. Objetivo: este estudio tiene como objetivo evaluar la asociación entre los síntomas otorrinolaringológicos y la positividad del SARS-CoV-2 confirmada mediante la reacción en cadena de la polimerasa de transcripción inversa (RT-PCR), así como la gravedad, duración y recuperación de estos síntomas en pacientes de la Fundación Santa Fe de Bogotá, un hospital de referencia de COVID-19 en Bogotá, Colombia. Métodos: estudio observacional, prospectivo, tipo casos y controles, realizado entre el 9 de octubre de 2020 y el 14 de enero de 2021. Los casos incluyeron adultos que obtuvieron una prueba positiva para el SARS-CoV-2 mediante RT-PCR. Los casos se emparejaron en una proporción de 2:1 con adultos sintomáticos seleccionados al azar con una prueba negativa, o con pacientes prequirúrgicos. Resultados: se incluyeron 130 casos y 253 controles entre los 10.004 pacientes sometidos a la prueba del SARS-CoV-2. La edad media era de 41,8 años (desviación estándar [DE]: 16,3). Los síntomas otorrinolaringológicos asociados a la positividad al SARS-CoV-2 fueron anosmia/hiposmia (adjusted odds ratio [aOR]: 5,82; intervalo de confianza [IC] del 95 %: 1,92-17,68), disgeusia/hipogeusia (aOR: 9,09; IC del 95 %: 2,86-28,92) y tos seca (aOR: 3,18; IC del 95 %: 1,56-6,48). La duración media de la anosmia/hiposmia y de la disgeusia/hipogeusia en los pacientes con SARS-CoV-2 positivos fue de 14,5 días y 15 días (rango intercuartílico [IQR]: 8-27), respectivamente. Hasta el 70,3 % y el 67,5 % de la población informó de una recuperación completa de la anosmia/hiposmia y la disgeusia/hipogeusia. En cuanto a la gravedad de los síntomas de anosmia/hiposmia y disgeusia/hipogeusia, el 62,1 % y el 65,4 % de la población positiva para SARS-CoV-2 los clasificó como graves. Sin embargo, solo el 6,1 % de ellos recibió tratamiento para estos síntomas. Conclusiones: los síntomas otorrinolaringológicos asociados con la positividad para SARS-CoV-2 son útiles para orientar el diagnóstico, pero establecer sus características clínicas también es esencial para un tratamiento adecuado.

Introduction: Otolaryngological disorders in COVID-19 patients have drawn attention worldwide. However, there is still no consensus regarding the prevalence, severity or recovery of these disorders. This study aimed to assess the association between otolaryngological symptoms and SARS-CoV-2 positivity confirmed by RT-PCR, as well as the severity, duration, and recovery of these symptoms in patients receiving care at Fundación Santa Fe de Bogotá, a COVID-19 referral hospital in Bogotá, Colombia. Methods: Observational, analytic, prospective, case-control study conducted between October 9, 2020, and January 14, 2021. Cases included adults who tested positive for SARS-CoV-2 by reverse transcription-polymerase chain reaction (RT-PCR). Cases were matched in a 2:1 ratio with randomly selected symptomatic adults with a negative test, or patients awaiting surgery. Results: Of 10004 patients tested for SARS-CoV-2, 130 cases and 253 controls were included. The mean age was 41.8 years (standard deviation [SD]: 16.3). The otolaryngological symptoms associated with SARS-CoV-2 positivity were anosmia/hyposmia (adjusted odds ratio [aOR]: 5.82; 95% confidence interval [CI]: 1.92-17.68), dysgeusia/ hypogeusia (aOR: 9.09; 95% CI: 2.86-28.92), and dry cough (aOR: 3.18; 95% CI: 1.56-6.48). The median duration of anosmia/hyposmia and dysgeusia/hypogeusia in SARS-CoV-2 positive patients was 14.5 days and 15 days (interquartile range [IQR]: 8-27), respectively. Up to 70.3% and 67.5% of the population reported a complete recovery of anosmia/hyposmia and dysgeusia/hypogeusia. Regarding the severity of anosmia/hyposmia and dysgeusia/hypogeusia symptoms, 62.1% and 65.4% of the SARS-CoV-2 positive population classified them as severe. However, only 6.1% of them received treatment for these symptoms. Conclusions: Otolaryngological symptoms associated with SARS-CoV-2 positivity are a useful guide to diagnosis, although adequate treatment also requires determination of their clinical characteristics.

Frequency of self-reported allergies at a high-complexity referral hospital in Colombia, a tropical Latin American country.

BACKGROUND: The frequency of allergic diseases in tropical Latin American populations is poorly understood, and certain particularities can impact their natural history and risk factors. OBJECTIVE: The study aimed to determine the frequency of self-reported allergies (allergic diseases, drug, and food allergies) in patients who attended the Hospital Universitario Fundación Santa Fe de Bogotá, Colombia. MATERIAL AND METHODS: A retrospective study was conducted to assess the frequency of self- reported allergies reported by all the patients who attended an allergy referral center between June and December 2019. RESULTS: A total of 60978 patients were included. Allergic rhinitis was reported by 1.51% (n = 921), asthma by 1.28% (n = 782), and atopic dermatitis by 0.41% (n = 250) of the study population. A higher frequency of self-reported allergic diseases (rhinitis, asthma, and dermatitis) was found in the younger populations, while drug allergies were more frequently reported in adults. The most frequently self-reported drug allergies were penicillin allergy (4.07%, n = 2479), and non- steroidal anti-inflammatory drug (NSAID) allergy (1.85%, n = 1116). The most commonly reported food allergens included shellfish (0.58%), fruits (0.54%), cow's milk protein (0.37%), and eggs (0.21%). CONCLUSION: The distribution of food allergens showed a higher frequency of shrimp and fruit allergies compared to previous studies on African, Asian, and Arabic tropical populations that describe a higher predominance of egg and milk allergies. Patients reporting allergic diseases should always be referred to the allergology department for confirmatory testing.

Prevalence and associated factors of allergic diseases in school children and adolescents aged 6-7 and 13-14 years from two rural areas in Colombia.

INTRODUCTION: The prevalence of allergic diseases is increasing worldwide, affecting about 30% of the population in low to middle-income countries. Research trends on allergic diseases within rural pediatric populations of Latin American countries is scarce. This study aimed to determine the prevalence of allergic diseases (allergic rhinitis, asthma, and atopic dermatitis) and their associated factors using the International Study of Asthma and Allergies in Childhood-III (ISAAC-III) questionnaire in school-aged children from two rural municipalities in Colombia. MATERIALS AND METHODS: This is a cross-sectional study. The ISAAC-III questionnaire was applied to school-aged children attending elementary schools in the municipalities of Soracá and Palmas del Socorro during 2018. The questionnaires were applied to adolescents aged 13-14 years and the parents of 6-7 years old children. Associations were estimated via bivariate and multivariate analysis. RESULTS: Among 261 school-aged children (58.2% adolescents), the prevalence of allergic diseases was: allergic rhinitis 11.49% (95% CI: 8.05-15.78), asthma 8.81% (95% CI: 5.82-12.7), and atopic dermatitis 6.13% (95% CI: 3.69-9.53). Associated factors for allergic rhinitis included: female sex (PR: 2.68, 95% CI: 1.17-5.26), asthma (PR: 4.69, 95% CI: 1.96-8.31), atopic dermatitis (PR: 3.55, 95% CI: 1.09-7.83), and higher maternal education (PR: 4.16, 95% CI: 1.45-8.25). CONCLUSIONS: The prevalence of allergic diseases in this rural pediatric population was lower compared with that of the previous reports from urban populations. Associated factors found in this study support previous studies. Research addressing modifiable environmental associations is so far scarce in Latin America; further studies are needed to reduce the burden of these diseases in rural populations.

Prevalence of extended high-frequency hearing loss among adolescents from two rural areas in Colombia.

OBJECTIVE: Worldwide research trends on the prevalence of hearing loss within young rural populations are scarce. Current evidence suggests extended high-frequency audiometry could be a sensitive predictor to detect subclinical hearing loss. This study aimed to determine the prevalence of hearing loss through conventional pure tone (0.25-8 kHz) and extended high-frequency (9-20 kHz) audiometry tests in a group of adolescents aged 13 to 19 years old from two rural areas of Colombia. A sociodemographic and associated factor for hearing loss questionnaire was applied. DESIGN: Cross-sectional study. STUDY SAMPLE: Three hundred sixty-six adolescents aged 13 to 19 years old from two rural municipalities in Colombia: Soracá, and Palmas del Socorro. RESULTS: Hearing loss prevalence assessed through pure tone audiometry was 3.28% in right ears and 3.83% in left ears while through extended high-frequency audiometry was 14.21% and 13.11%, respectively. Associated factors found by the logistic regression were age (OR: 1.36; CI 95% 1.13-1.64) and obesity (OR: 3.74; CI 95% 1.07-13.11). CONCLUSIONS: Using 15 dB as the normal hearing threshold parameter for audiometric frequencies, our results suggest that extended high-frequency hearing loss is already widespread among rural adolescents. This highlights the need for research on extended high-frequency audiometry in rural school-aged children.
