Analysis on Risk Factors of Depressive Symptoms in Occupational Noise-induced Hearing Loss Patients: A Cross-sectional Study

Abstract Background Significant sex differences exist in hearing physiology, while few human studies have investigated sex differences in noise-induced hearing loss (NIHL), and the sex bias in previous studies resulted in inadequate female data. The study aims to investigate sex differences in the characteristics of NIHL to provide insight into sex-specific risk factors, prevention strategies and treatment for NIHL. Methods This cross-sectional study included 2280 industrial noise-exposed shipyard workers (1140 males and 1140 females matched for age, job and employment length) in China. Individual noise exposure levels were measured to calculate the cumulative noise exposure (CNE), and an audiometric test was performed by an experienced technician in a soundproof booth. Sex differences in and influencing factors of low-frequency (LFHL) and high-frequency hearing loss (HFHL) were analyzed using logistic regression models stratified by age and CNE. Results At comparable noise exposure levels and ages, the prevalence of HFHL was significantly higher in males (34.4%) than in females (13.8%), and males had a higher prevalence of HFHL (OR = 4.19, 95% CI 3.18 to 5.52) after adjusting for age, CNE, and other covariates. Sex differences were constant and highly remarkable among subjects aged 30 to 40 years and those with a CNE of 80 to 95 dB(A). Alcohol consumption might be a risk factor for HFHL in females (OR = 3.12, 95% CI 1.10 to 8.89). Conclusions This study indicates significant sex differences in NIHL. Males are at higher risk of HFHL than females despite equivalent noise exposure and age. The risk factors for NIHL might be different in males and females.

Objective: To determine the frequency and risk factors of occupational noise induced hearing loss. Study Design: Cross sectional study. Place and Duration of Study: Dispensary Unit of Jaith Bhuta Sugar Mill near Rahim Yar Khan, Southern Punjab.from Aug 2017 to Jan 2018. Methodology: This study was conducted using nonprobability consecutive sampling. n=300 workers of bothgenders aged 18-40 years were assessed. Basic demographic parameters, otoscopic examination and Pure Tone Audiometry were used for data collection. The Data was analyzed by using SPSS version 21. Results: Study included 215 (71.7%) males and 85 (28.3%) females with male to female ratio of 2.53: 1 and meanage of 28.34 ± 4.61 years. The frequency rate of hearing impairment (HI) was 90 (30%) out of 300 respondents inthis study. Out of 70 (100%) of respondents were affected with duration of job of 6-10 years. There was significant association between gender, age, education, duration of noise exposure with occupational noise induced hearing loss with p-value <0.001. Conclusion: There was high frequency of occupational noise induced hearing loss (ONIHL) with significantrisk factors being level and duration of exposure to noise (ETN), age, gender, education and hearing protectivedevices (HPD)’s.

Study Setting

Objectives: Occupational noise induced hearing loss (ONIHL) is considered an important reason responsible for disability around the world. As industrial workers are frequently exposed to occupational noise, sensorineural hearing loss (SNIHL) is commonly found in this set of population. This study was conducted to determine the frequency of noise induced hearing loss (NIHL) in industrial workers of Multan. Study Design: Descriptive, cross-sectional study. Setting: Department of Otorhinolaryngology, Nishtar Hospital, Multan. Period: 16th April 2018 to 15th October 2018. Material & Methods: A total of 316 industrial workers of age 25-65 years and both genders were included. Audiometric testing was performed in a sound free room where calibrated digital audiometer ALPS AD 2100 was used. Hearing threshold was obtained for both ears at 250-8 kHz. NIHL was noted. Results: Mean age was 45.56 ± 10.95 years. Most patients, 170 (53.80%) were 25-45 years of age. There were 188 (59.49%) male and 128 (40.51%) female. Mean duration of experience was 11.14 ± 5.86 years. NIHL was found in 95 (30.06%) patients. Conclusion: Frequency of NIHL among industrial workers is high. Factory owners and workers should consider adopting preventive and safety measures to control noise induced hearing loss.

Abstract Introduction To explore the prevalence of depressive symptoms and the associated risk factors in frontline nurses under COVID-19 pandemic. Methods This cross-sectional study was conducted from February 20, 2020 to March 20, 2020 and involved 562 frontline nurses. The effective response rate was 87.68%. After propensity score matched, there were 498 participants left. Extensive characteristics, including demographics, dietary habits, life-related factors, work-related factors, and psychological factors were collected based on a self-reported questionnaire. Specific scales measured the levels of sleep quality, physical activity, depressive symptoms, perceived organization support and psychological capital. Adjusted odds ratios and 95% confidence intervals were determined by binary paired logistic regression. Results Of the nurses enrolled in the study, 50.90% had depressive symptoms. Three independent risk factors were identified: poor sleep quality (OR = 1.608, 95% CI: 1.384–1.896), lower optimism of psychological capital (OR = 0.879, 95% CI: 0.805–0.960) and no visiting friend constantly (OR = 0.513, 95% CI: 0.286–0.920). Conclusions This study revealed a considerable high prevalence of depressive symptoms in frontline nurses during the COVID-19 outbreak, and identified three risk factors, which were poor sleep quality, lower optimism of psychological capital, and no visiting friend constantly. Protecting mental health of nurses is important for COVID-19 pandemic control and their wellbeing. These findings enrich the existing theoretical model of depression and demonstrated a critical need for additional strategies that could address the mental health in frontline nurses for policymakers.

Introduction: Noise Induced Hearing Loss (NIHL) is an occupational health hazard linked with noise exposure of more than 85 dB. Aircraft noise and other occupational noise exposure cause military aviators more susceptible to NIHL than commercial jet pilots. Aim: To find out the prevalence of noise induced hearing loss among different military aircrew population with special emphasis on identifying the associated risk factors. Materials and Methods: This cross sectional study was conducted on Kuwait Air force pilots those who came for annual medical checkup from July 2010 to July 2012. Audiometry of all subjects was done by ENT specialist and necessary data were collected by structured questionnaires. All data were analyzed by SPSS (Statistical Package for the Social Sciences) version 17.0 Results: Out of 221 aircrew 32 (14.48%) developed NIHL. Hearing loss was mild to moderate and predominately at high frequencies. Most affected group was helicopter pilots. Pilots of more than 40 years of age and those who had more than 1000 flying hours had mean hearing threshold more than other groups. The right ear was affected in majority of cases than left ear. Conclusion: Noise exposure to aircrew is inevitable so hearing loss prevention strategies might play a pivotal role to save aircrew hearing. Active surveillance of hearing protection practices might have beneficiary effect. Steps can be taken for early detection of NIHL and hearing conservation program.
