The cashew processing industry plays a vital role in supporting the livelihoods of a large number of individuals in southern Kerala. Therefore, this study aimed to determine the prevalence of occupational health problems and associated factors among cashew workers. This cross-sectional survey was conducted among 360 cashew workers. Socio-demographics, musculoskeletal disorders (MSDs), respiratory symptoms, and dermatological problems were collected through a scheduled interview. Log binomial regression analysis was done. The prevalence of MSDs, chronic lung diseases (CLDs), and dermatological problems were 55.8%, 18.9%, and 47.5%, respectively. Female workers and workers with a lower education level were significantly more likely to report MSDs. Male workers and those with more years of employment were significantly more likely to report CLDs. Workers in the shelling and peeling section were significantly more likely to report dermatological problems. Targeted interventions to improve the occupational health of cashew workers are needed.

Background: Occupational noise-induced hearing loss (ONIHL) is the commonest occupational disease globally. However, literature on ONIHL in airport employees of developing countries is scarce.

Aims: To assess the burden of ONIHL and its associated factors among employees working at an international airport in Eastern India.

Methodology: A cross-sectional study was conducted among 212 such airport employees who had been working in the airport for >1 year. By stratified random sampling, participants were recruited from airfield, terminal, and administration sections. ONIHL was measured using a portable audiometer and noise exposure using a sound-level meter.

Results: The mean age was 34.1 ± 9.2 years, 89.2% were men. The mean year of working in the airport was 7.6 ± 6.3 years. The 8-hour-time-equivalent noise exposure ranged from 56.6 to 86.5 dBA. Approximately 50% of the employees do not wear any hearing protection equipment when working. Prevalence of ONIHL was found to be 7.6%. On multivariable analysis, higher noise exposure and use of hearing protection equipment were found to be positively and negatively associated with ONHIL, respectively.

Conclusion: ONIHL was found to be prevalent among employees working at the airport, and focus should be given on reducing noise exposure levels and ensuring use of protective equipment among the employees.

Context: Agriculture is one of the occupations with the highest risk of injuries and fatalities but the farmers are ignorant about eye care and eye safety.

Aim: The current study aims at understanding the occupational hazard and ocular morbidities associated with agriculture and the effect of safety eyewear.

Settings and design: Multicenteric, cross-sectional, observational study was conducted in two states of India: Tamil Nadu and Karnataka. Subjects were agriculture workers recruited by convenience sampling.

Methods and material: The study was done in three phases: Phase 1: Visual task analysis (VTA), Phase 2: Comprehensive eye examination, and Phase 3: Spectacle compliance assessment. The Standard of Living Index scale was administered to assess the socioeconomic status of the participants.

Statistical analysis used: Descriptive statistics and logistic regression.

Results: A study involving 276 workers (39.4% male, 65.2% female) found that VTA agricultural tasks were visually less demanding but hazardous, carrying the risk of ocular and nonocular injuries. Ocular injuries accounted for 9.4% (26 cases), while nonocular injuries accounted for 9.8% (27 cases). Spectacle compliance assessment revealed that 91.8% (157 out of 171 workers) reported improved visual comfort, reduced dust exposure, and enhanced safety with safety eyewear.

Conclusions: This study illustrates numerous types of hazards associated with the occupation of farming. The study population had a 9.4% prevalence of ocular injuries. Refractive safety eyewear was reported to improve worker visual comfort.

Background: Women roll beedis from a young age and expose continuously to unburnt tobacco dust for many years. Due to poverty, ignorance, and lack of literacy, women and young individuals engage in less profitable occupation. The study was conducted in a large sample to know the occupational health morbidities in rural women.

Materials and methods: Women beedi rollers and nonbeedi rollers living in villages of Jagitial and Nizamabad districts were selected for the study. Individuals who signed consent are interviewed about their health profile using a predesigned standard questionnaire.

Result: A high frequency of general health problems was observed in the present study. Hypertension, body pains, and headache are the most prevalent health issues observed in more than half of beedi rollers.

Conclusion: Awareness programs must be implemented to decrease the health hazards and provide alternate job opportunities for better health.

The World Health Organization (WHO) has launched a new 10-year cardiovascular risk prediction recommendation known as the WHO Cardiovascular Risk Chart 2019 (WHO CRC). However, there is currently no assessment available regarding the relationship between ASCVD classic and occupational profiles to WHO CRC, specifically in occupational settings and in the context of the Indonesian Heart Association's (IHA) adjusted version of the WHO CRC for South-East Asia (WHO CRC-INA). This study aims to fill this gap by examining the relationship between classic (Atherosclerosis Cardiovascular Disease) ASCVD and occupational profiles within the oil and gas industry, specifically the WHO CRC-INA. This study is analytical cross-sectional research data were analyzed using the Chi-square test and logistic regression, with a significance level of P < 0.05. The research using total sampling method amounted to 240 workers from January to May 2022 of Medical Check Up (MCU) in a major oil and gas company. The ASCVD risk measurement instrument uses the final score of the WHO CRC-INA, grouped into low- and medium-high risk. Analysis showed that occupational profiles had a relationship with WHO CRC-INA medium-high risk, as seen in the bivariate analysis for shift work and work type (P = 0.018; OR = 2,045) had a relationship with WHO CRC-INA medium-high risk.

Background: This study seeks to define the pulmonary function of a considerably large group in one of the largest automotive companies in Iran. The aim of this study was to compare the two groups of spot-welding (exposed) and assembly line (unexposed) workers in terms of pulmonary function and conclude the probable impacts of metal fumes on pulmonary function in the two groups.

Methods: A total of 1,798 spot-welding personnel and 2,160 assembly line personnel were compared in terms of pulmonary function. Moreover, 120 breathing zone samples were collected from the welders' metal fumes and were analyzed. The parameters of age, anthropometric indices, smoking, and pulmonary symptoms were also compared with across the two groups.

Results: Results revealed the FEV₁ mean of the total population to be 3.9 ± 0.5 liters and FVC to have been 4.9 ± 0.7 liters. Besides, predicted FEV₁ and FVC percentages across the whole population were close to 100%, suggesting the better condition of the studied population compared with normal individuals in the society. All the parameters of age, weight, height, and smoking status were similar in the two groups, and no statistically significant difference was observed between the two groups in terms of pulmonary functions.

Conclusion: Implementation of professional health and health improvement programs, running screening programs, and hiring personnel with no history of mild pulmonary disorders, and healthy workers effect at the recruitment stage could be the reasons behind the lack of significant difference between the two exposed and unexposed groups to metal fumes in the automotive industry in terms of pulmonary function.

Context: Low light in mines can cause ocular problems such as binocular vision impairment and poor hand-eye coordination. These eye diseases must be monitored.

Aims: To evaluate the binocular vision status of coal mine workers.

Settings and design: This was a prospective cross-sectional study of the coal mining industry in Digwadih, Jharkhand.

Methods and material: In the present study, 134 coal miners underwent a thorough, comprehensive ocular examination and binocular vision evaluation; seventy were excluded because of ocular disorders. After discussing the goals of the study, the subjects provided signed informed consent. For statistical analysis, descriptive statistics were analyzed using Microsoft Excel. The normality of the data was then verified using the Kolmogorov-Smirnov test.

Results: All participants were male and aged between 25 and 35 years. Nonstrabismus binocular vision dysfunctions (NSBVDs) were observed in coal miners. Convergence insufficiency was the most prevalent factor. Apart from the NSBVD, many coal miners have a chalazion with the highest percentile of 11.2.

Conclusions: Poor mine lighting causes NSBVD, which affects miners' vision. Binocular vision defects may reduce productivity if not detected or treated.

Purpose: The mining sector plays a pivotal role in meeting global resource demands, necessitating the extensive use of heavy earth-moving machinery (HEMM). Among these, load-haul-dump (LHD) mining vehicles are vital but expose operators to whole-body vibration (WBV) and shocks during their duties. Research indicates potential health risks associated with occupational WBV exposure, including musculoskeletal disorders. Evaluating these risks typically employs ISO 2631-1:1997, which, however, has limitations in addressing long-term exposure and shock effects.

Methods: This study quantifies the health risks of LHD operators in Indian underground coal mines using ISO 2631-5:2018 and compares it to ISO 2631-1:1997. The methods for risk quantification from WBV vary between the two standards, leading to a comprehensive comparison. In addition, a cross-sectional study was undertaken to assess self-reported musculoskeletal pain among LHD operators.

Results: The results were compared in accordance with frequency-weighted root mean square (RMS) values, vibration dose values (VDV), daily compressive dose (S_d ^A), and the risk of injury (R^A) factor. The assessment using A(8), VDV, S_d ^A, and R^A produced diverse evaluations, influencing varying perspectives on occupational health despite significant risks. ISO 2631-5:2018 consistently suggested a lower health risk for LHD operators as opposed to ISO 2631-1:1997. Seat effective amplitude transmissibility (SEAT) values showed amplification of vibration in the range of 4-8 Hz. Self-reported musculoskeletal pain indicated the prevalence of discomfort among operators.

Conclusion: The study emphasizes a cautious approach when interpreting results and shaping guidelines to ensure sustainable development through the well-being of mining industry workers.
