RESUMEN
Introducción: La audición es la vía habitual para adquirir el lenguaje, lo cual permite el desarrollo del pensamiento y el conocimiento; la pérdida auditiva puede afectar la capacidad de aprendizaje y comunicación en el niño y ocasionar alteraciones en su comportamiento y rendimiento académico. Objetivo: Determinar la relación entre el nivel auditivo y el rendimiento académico en estudiantes de educación primaria de una institución educativa pública de Lima. Métodos: Estudio observacional, correlacional y transversal. Se realizó otoscopía y audiometría en 94 alumnos del sexto año de primaria de la institución educativa Santa Rosa de Lima, en Los Olivos-Lima. Se usó como instrumento el otoscopio, el audiómetro y las notas finales de cada alumno del primer semestre académico 2022. Se analizó la relación mediante el coeficiente de correlación de Rho de Spearman. Resultados: El 35,1% de estudiantes presentaron hipoacusia leve y el 64,9%, normoacusia. El rendimiento académico promedio de la muestra fue 14,74; el rendimiento académico promedio de los normoacúsicos; 14,89 y el de los hipoacúsicos, 14,48. En el análisis de correlación de Rho de Spearman, se encontró correlación positiva entre nivel de audición y rendimiento académico (0,200). Conclusiones: Existe relación positiva entre el nivel de audición y rendimiento académico en estudiantes del sexto año de primaria de la institución educativa Santa Rosa de Lima en Los Olivos.
Introduction: Hearing is the usual way to acquire language, which allows us the development of thought and knowledge; hearing loss can affect the ability to learn and communicate in children and cause alterations in their behavior and academic performance. Objective: To determine the relationship between hearing level and academic performance in primary school students from a public educational institution in Lima. Methods: Observational, correlational and cross-sectional study. Otoscopy and audiometry were performed in 94 students of the sixth year of primary school of the Santa Rosa de Lima educational institution, in Los Olivos-Lima. Was used the otoscope, the audiometer and the final grades of each student of the first academic semester 2022 as instruments. The relationship was analyzed using Spearman's Rho correlation coefficient. Results: 35.1% of students had mild hearing loss and 64.9% had normal hearing loss. The average academic performance of the sample was 14.74; the average academic performance of the normoacusic students, 14.89 and the average academic performance of the hearing impaired, 14.48. In the Spearman's Rho correlation análisis, it was found a positive correlation between hearing level and academic performance (0.200). Conclusions: There is a positive relationship between hearing level and academic performance in sixth grade students of the Santa Rosa de Lima- Los Olivos educational institution.
RESUMEN
Background The correlation between noise exposure and negative emotions of noise-exposed workers has received increasing attention and related studies have been reported. However, there is a lack of research on the path and effect analysis of the relationship between noise exposure and negative emotions, which will contribute to a more comprehensive understanding of the health damage characteristics of noise in addition to hearing loss. Objective To explore the path and effects of cumulative noise exposure, tested hearing thresholds, and conscious hearing level of noise-exposed workers on negative emotions. Methods Using stratified random sampling, 312 noise-exposed workers from a machinery and equipment manufacturing enterprise were selected. Occupational history, negative emotions (including the feelings of stress, anxiety, and depression), and conscious hearing level of the workers were investigated using the Depression-Anxiety-Stress Scale (DASS-21) and a self-made questionnaire. The hearing threshold of the workers was measured by pure tone air conduction audiometry. Sound level meter was used to measure noise equivalent sound level at selected work sites. Individual cumulative noise exposure was estimated based on work site noise level and personal noise exposure history. Path analysis was used to analyze potential mediating effects of workers' hearing thresholds and conscious hearing levels on the relationship between noise exposure and negative emotions (including stress, anxiety, and depression). Results The positive rates of negative emotions among the 312 noise-exposed workers were 18.27% (57/312) for stress, 46.79% (146/312) for anxiety, and 28.53% (89/312) for depression; the cumulative noise exposure ranged from 101.0 to 136.1 dB(A)·d, with an average of 125.69 dB(A)·d. The distributions of tested hearing thresholds and conscious hearing levels among the workers exposed to noise were significantly inconsistent (P<0.001), with both unweighted and weighted Kappa values less than 0.4. The percentage of workers with conscious hearing levels higher than their hearing threshold levels was 16.0%, and the percentage of workers with conscious hearing levels lower than conscious hearing levels was 38.7%. The path analysis results showed that tested hearing thresholds had no mediating effect on the relationship between cumulative noise exposure and negative emotions. There was a partial mediating effect of conscious hearing level on the relationship between cumulative noise exposure and negative emotions, with a mediating effect value of 0.06 (95%CI: 0.03, 0.11) and a mediating effect ratio of 28.57%. Conclusion Conscious hearing plays a partial mediating role in the relationship between cumulative noise exposure and negative emotions of noise-exposed workers, while tested hearing thresholds do not.
RESUMEN
Abstract Introduction Despite much advancement in medicine, endocrine and metabolic diseases remain an important cause of morbidity and even mortality in children. Objective The present study was planned to investigate the evaluation of hearing that also includes high frequencies, and the presence and degree of vertigo and tinnitus symptoms in pediatric patients diagnosed with endocrine diseases such as type 1 diabetes mellitus (DM), growth hormone deficiency (GHD), obesity, idiopathic short stature, and precocious puberty Methods The present study included a patient group of 207 children patients diagnosed with endocrine disease (95 males, 112 females; mean age 9.71 years old [range 6-16 years old]) and a control group including 55 healthy children who do not have any kind of chronic disease (26males, 29 females;mean age 9.33 years old [range 6-16 years old]). The subjects underwent a hearing test with frequencies between 250 and 20,000 Hz. The vestibular and tinnitus symptoms were evaluated with the Pediatric Vestibular Symptom Questionnaire. Results Out of 207 patients in the patient group, 5 (2.4%) had hearing loss in pure tones, 10 (4.8%) had it in high frequencies, 40 (19.3%) had tinnitus symptoms, and 18 (8.7%) had vertigo symptoms. A total of 4 out of 207 patients in the study group (1.9%), 2 out of 59 with type 1 DMpatients (3.4%), 1 out of 46 with GHD (2.2%), and 1 out of 43 obesity patients (2.3%) had hearing loss, vertigo, and tinnitus symptoms. Conclusions Our results suggest that some childhood endocrine diseases can cause some changes in the inner ear, although the exact cause is unknown. Perhaps, a detailed hearing and balance examination should be a routine in a child diagnosed with an endocrine disease.We think it is necessary to work on more comprehensive patient groups and tests in the future.
RESUMEN
Objective: In this study our main goal is to evaluate thehearing level among the workers of cement industry.Methodology: This Cross-sectional observational study wasconducted at Department of Physiology, Chittagong MedicalCollege, Chittagong and Heidelbargh Cement Bangladesh Ltd.East Halishar, Chittagong, One year (January 2011 toDecember 2011). Where total number of 800 (Eight hundred)subjects were included. During the study, all subjects wereselected purposively on the basis of noise exposure studyprocedure. After selection and proper counseling, the aim,objective and procedure of the study was explained in detailsto all subjects, in the cement industry.Results: During the study highest frequency of hearing losswas found in 30-40 years age group. Most of the patientsworked in production area for 5-10 years. most of the patientsexposed to 70-80dB, 41.4%.51.6% patients exposed >8 hoursdaily and 65.5% patients exposed 42-48 hours weekly.Conclusion: From our study we can conclude that the studyclearly demonstrated that noise is a serious health hazard inthe cement industry. Hearing threshold for the subjectsexposed to noise increase with the progress of age andduration of employment. Further study is needed for betteroutcome.
