Relationships of job hazards, lack of knowledge, alcohol use, health status and risk taking behavior to work injury of coal miners: a case-control study in India

Exploring the determinants of health-promoting behaviors among miners: A text mining and meta-analysis

The health-promoting behaviors of miners are of great significance to their physical and mental well-being. With a focus on enhancing their overall health, this study aimed to explore the determinants and influencing mechanisms of health-promoting behaviors in miners. Initially, the latent Dirichlet allocation (LDA) model was utilized to extract topical keywords from literature over the last 23 years and to categorize the determinants based on integrating the health promotion model and the health belief model. Subsequently, a meta-analysis was performed based on 51 related empirical research to explore the mechanisms between determinants and health-promoting behaviors. The results indicated that (1) the factors influencing miners' health-promoting behaviors can be divided into four dimensions: physical environment, psychosocial environment, individual characteristics, and health beliefs. (2) Noise was negatively related to health-promoting behaviors, while protective equipment, health culture, interpersonal relationships, health literacy, health attitudes, and income were positively related to health-promoting behaviors. (3) Protective equipment and health literacy were positively related to perceived threat, whereas interpersonal relationships were positively related to perceived benefits. This study sheds light on the mechanisms influencing miners' health-promoting behaviors and could inform behavioral interventions in occupational health.

Opioid Use Disorder Community Education Events: Rural Public Health Implications

The opioid overdose epidemic continues to disproportionately impact underserved rural areas throughout the nation, with many of these rural areas experiencing greater opioid-related mortality rates than their urban counterparts. With limited treatment infrastructure and resources, two rural communities in Southeast Utah utilized community-based participatory research collaboration principles to develop, implement, and evaluate a series of evidence-based community opioid education events. This practical and quantitative study surveying 123 participants describes the collaborative efforts of two rural communities in addressing the devastating impacts of the opioid overdose epidemic and reflects on the success of the events via descriptive analysis of summary data. These events increased participants' reported perceptions of and knowledge in four main education areas: stigma reduction, prevention and treatment awareness, naloxone education and use, and resource location awareness. Post-event surveys further supported these results, revealing improved learning in each of these four areas, indicating increased knowledge toward opioid use disorder treatments and stigma reduction. In addition, participants identified key takeaways such as local resource awareness and dismantling stigma as effective strategies to reduce the negative effects of the opioid overdose epidemic. This model for rural community education supports previous research and serves as an effective strategy of public health practice to address the opioid overdose epidemic on a local level.

Structural equation modelling of work related musculoskeletal disorders among dumper operators

The aim of this study is to investigate the impact of personal factors, habitual factors, and work-related factors on work-related musculoskeletal disorders (WRMSDs) among dumper operators. In total, 248 dumper operators working in an iron ore mine were considered for this study. A questionnaire was developed and administered to collect dumper operators' personal, habitual, and work-related data. The reliability of the questionnaire was cross-checked by Cronbach alpha and the test-retest method. The values of Cronbach alpha for all latent variables were above 0.7, and the correlation coefficient of the questionnaire items at Time 1 and Time 2 was above 0.82. After verifying the validity (i.e., convergent and divergent) of the questionnaire data, the relationship between the factors under consideration was examined by structural equation modeling (SEM). The SEM demonstrated a moderate fit, with [Formula: see text] value of 1.386, comparative fit index (CFI) of 0.86, goodness-of-fit index (GFI) of 0.72, adjusted goodness-of-fit index (AGFI) of 0.69, Tucker-Lewis Index (TLI) of 0.83, normed fit index (NFI) of 0.71 and root mean square error of approximation (RMSEA) of 0.051. The SEM analysis revealed a positive relationship between WRMSDs and personal factors (with path coefficient = 0.313 and p < 0.05) as well as work-related factors (with path coefficient = 0.296 and p < 0.05). However, the relationship between WRMSDs and habitual factors was not statistically significant (with path coefficient = 0.142 and p > 0.05). Overall, this study provides valuable insights into the factors that influence the prevalence of WRMSDs among dumper operators. The findings highlight the significance of personal and work-related factors by which one can make a positive decision to prevent and reduce the incidence of WRMSDs among dumper operators.

Occupational injuries among female seafood processing workers in Prakasam district, Andhra Pradesh, India

Women play a significant role in the processing of the seafood after the harvesting process and are mostly engaged in grading, peeling, cutting, and packing activities. Injuries during their job make them vulnerable to many problems and lead to many severe consequences. The present study aimed to identify the frequency and factors associated with occupational injuries among the workers in Prakasam district, Andhra Pradesh. This cross-sectional study included 257 women seafood processing workers. Simple random sampling technique was used to select the participants. The data were collected through face to face interviews using a predesigned questionnaire. Data were analyzed using SPSS. The prevalence of injuries among 257 women seafood processing workers was 74.3 percent. Age of the worker, job satisfaction, working hours per day, breaks duration between work, and blanching of hands (paleness of hands due to vasoconstriction) were found to be statistically significantly associated factors with injury occurrence among women seafood processing workers. Thus, to conclude, the frequency of occupational injuries among the women seafood processing workers is high and is associated with several occupational factors.

Occupational Injuries and Associated Factors Among Small-Scale Woodwork Industry Workers in Hawassa, Southern Ethiopia: A Cross-Sectional Study

BACKGROUND

Occupational injuries are still a major public health problem and one of the leading causes of disability, morbidity, and mortality. This study aimed to assess occupational injuries and associated factors among workers in the small-scale woodworking industry in Hawassa city, southern Ethiopia.

MATERIALS AND METHODS

An institutional-based cross-sectional study was conducted among 418 randomly selected small-scale woodworking industry workers. Questionnaires and an observational checklist were used to collect data. The data was entered into Epi data version 3.1 and analyzed using SPSS version 21. Multivariate logistic regression analysis with 95% CI and P < .05 was used to identify factors associated with occupational injury.

RESULTS

The prevalence of at least one occupational injury in the previous 12 months among small-scale woodworking industry workers was 41.6% [95% CI: 36.9-46.4]. Work experience 1 to 2 years [AOR = 2.8, 95% CI: 1.49-5.2], working more than 48 hours per week [AOR = 2.2, 95% CI: 1.41-3.49], lack of occupational safety and health (OSH) training [AOR = 2.5, 95% CI: 1.35-4.75], and non-use of personal protective equipment (PPE) [AOR = 3.3, 95% CI: 1.85-5.83] were factors significantly associated with occupational injury.

CONCLUSIONS

In this study, the prevalence of occupational injuries among workers in the small-scale woodworking industry was high. Lack of OSH training, non-use of PPE, work experience of 1 to 2 years, and working more than 48 hours per week were all factors that contributed to occupational injuries. Therefore, workers in the small-scale woodworking industry should receive ongoing occupational safety and health (OSH) training, and personal protective equipment (PPE) should be provided and monitored.

Contributing effects of individual characteristics, behavioural and job-related factors on occurrence of mining-related injuries: A systematic review

BACKGROUND

Occupational health and safety (OHS) is a complex system due to its three components, namely human, technological and organizational factors. The interplay between the three systems causes workplace accidents and, subsequently, injuries. The body of research currently available demonstrates a disparity in the focus on contributors that cause mining-related injuries beyond the presence of hazards.

OBJECTIVE

The aim of this paper was to systematically review and synthesise peer-reviewed published studies that have investigated whether certain individual characteristics, behavioural factors and job-related factors predict mining-related injuries.

METHODS

Databases were searched and peer-reviewed publications from 2004 to 2020 were retrieved and analysed. Only 24 from 3073 identified articles were retained for review and synthesis following careful screening. Most identified studies were either cross-sectional or case-control studies, and they were rated as moderate-to-good quality.

RESULTS

The review results showed that there is a diverging view in relation to risk factors that cause mining-related injuries. Some publications suggested that old age, male miners, married miners, less educated miners, less experienced miners, alcohol and drug usage, poor working conditions, poor management or supervision, job dissatisfaction and job stress predict injury events while other studies found contradictory relationships or insignificant statistical associations.

CONCLUSIONS

Despite the fact that studied risk factors have been well-established in other industries, there is a significant gap in mining that needs further examination. It is imperative that health and safety intervention strategies are devised and implemented for vulnerable groups.

Awareness of occupational hazards, and attitudes and practices towards the use of personal protective equipment among informal woodworkers: the case of the Sokoban Wood Village in Ghana

We investigated the awareness of occupational hazards, and attitudes and practices towards the use of personal protective equipment (PPE) among informal woodworkers of the Sokoban Wood Village in Ghana. Structured questionnaires were used to collect primary data from 355 woodworkers and analysed using descriptive statistics and logistic regression. The results showed that the workers are aware of PPE and knew about injuries they are exposed to. Most woodworkers had a positive attitude in terms of their perception on the necessity to use PPE but had a low frequency of PPE usage. Educational level, job type, length of service and marital status are the socio-demographic characteristics that significantly influence woodworkers' compliance with health and safety regulations. We recommend that institutions charged with enforcement of occupational health and safety regulations should extend their monitoring roles to informal workers and liaise with local companies to supply PPE to informal woodworkers at subsidized costs.

A Comprehensive Review of Work-Related Musculoskeletal Disorders in the Mining Sector and Scope for Ergonomics Design Interventions

OCCUPATIONAL APPLICATIONS Work-related Musculoskeletal Disorders (WMSDs) are prevalent in many industries worldwide, including the large and labor-intensive mining sector. A systematic review was carried out to understand problems in the mining sector issues from three broad perspectives: 1) the prevalence of WMSDs among miners; 2) the association of occupational, psychosocial, environmental, and other risk factors with WMSDs causation; and 3) ergonomics interventions already proposed or implemented, and scope for design interventions. Our review revealed that automation, job aids, and displays are methods suitable for ergonomic design interventions. Ergonomic intervention strategies at various hierarchical levels, and the successive way forward as proposed in our review, could act as a catalyst in formulating problem-specific solution strategies by the participation of diverse stakeholders to implement a more human-centric workplace.

Associations of job-related hazards and personal factors with occupational injuries at continuous miner worksites in underground coal mines: a matched case-control study in Indian coal mine workers

A wide range of job-related hazards and personal factors may be associated with injury occurrences at continuous miner worksites but their role has been little documented. To address this issue, a case-control study in India was conducted to compare 135 workers with an injury during the previous 2-yr period and 270 controls without injury during the previous 5-yr period (two controls for each injured worker, matched on age and occupation). Data were collected through face-to-face interviews using standardized questionnaire and analyzed using conditional logistic regression models. We found that the injury occurrences were multifactorial and associated with hand tool-related hazards (adjusted odds ratio/ORa=3.69, p<0.01), working condition-related hazards (ORa=3.11, p<0.01), continuous miner-related hazards (ORa=1.95, p<0.05), and shuttle car-related hazards (ORa=6.95, p<0.001), along with big family size, no-formal education, and presence of disease (adjusted odds ratios varying between 2 to 4). Stratified analyses showed that among the 36-60 yr-old workers, hand tool-related hazards, working condition-related hazards, and shuttle car-related hazards had significant ORa (6.62, 4.38 and 15.65, respectively with p<0.01,) while among the younger workers, only shuttle car-related hazards had significant ORa (4.25, p<0.05). These findings may help to understand the risk patterns of injuries and to implement appropriate prevention strategies.

Exploring the Effect of Different Performance Appraisal Purposes on Miners’ Organizational Citizenship Behavior: The Mediating Role of Organization Identification

This study theorized and examined the effect of performance appraisal purposes on miners’ organizational citizenship behavior (OCB) via organizational identification. Survey data from 700 miners in state-owned Chinese coal mine enterprises were analyzed using multiple regression and bootstrap sampling. Results indicated that both developmental purpose of the performance appraisal and evaluative purpose of the performance appraisal had positive effects on overall OCB and its four dimensions via organizational identification. Furthermore, developmental purpose of the performance appraisal had a stronger relationship with overall OCB and its four dimensions than evaluative purpose of the performance appraisal. This study provides practical guidance to assist Chinese and even Asian coal mining enterprises in deciding how to motivate miners’ OCB through improving a performance appraisal system and how to strengthen miners’ organizational identification.

Characteristic Analysis of Unsafe Behavior by Coal Miners: Multi-Dimensional Description of the Pan-Scene Data

As a high-risk occupation, coal mining has many accidents, primarily due to the unsafe behavior of coal miners. Based on the research of analysis of unsafe behavior and pan-scenario data of miners, a theoretical framework for the analysis of unsafe behavior characteristics was proposed in this paper. The collected data were divided into realistic scenes and abstract scenes according to different manifestations; the pan-scene data were described from the eight dimensions of time, behavioral trace, location, behavioral property, behavioral individual, degree, unsafe action, and specialty using a quantitative method for the structure conversion; and the rules were discovered through cluster analysis and association analysis. A total of 225 coal mine gas explosion accidents were used for analysis, and the pan-scene data description and structure conversion of unsafe behavior that caused these accidents were realized. In a certain cluster, the distribution rules of dimensions and the interaction between different dimensions of unsafe behavior were explored after analysis. The results show that the proposed eight dimensions can fully explain the basic characteristics and attributes of the unsafe behavior of coal miners. The structure conversion can reduce the workload of managers and effectively improve the safety data processing capabilities, and the result of data analysis can provide data support and a management basis for safety management. A new method and thought for the data analysis of miners' unsafe behavior is provided.

Prevalence of self-reported work-related illness and injuries among building construction workers, Shiraz, Iran

The construction industry is one of the largest and most hazardous industries in the world, which has a direct role in the development of countries. The purpose of this study was to investigate the prevalence of self-reported work-related illness and injuries among construction workers in Shiraz, Iran. 850 randomly selected workers from 2450 construction sites completed a self-statement questionnaire regarding the prevalence of self-reported work-related illness and injuries (WRIIs), in Shiraz, Iran. The association of WRII with demographic variables were studied. The overall prevalence rate of occupational injuries was 31 %. Musculoskeletal disorders (53.3 %), eye diseases (34.1 %) and skin diseases (30.1 %) have been the most prevalent work-related illnesses among construction workers, respectively. The prevalence of WRIIs among construction workers was significantly associated with age, education, marriage, work experience, safety training programs and number of workers in the workplace as well as employment status. Considering the high prevalence of WRIIs among construction workers, more stringent occupational safety and health interventions are recommended in construction workplaces.

Mental health in underground coal miners

As mental health goes beyond the simple absence of mental disorders, this paper characterized mental health components in 89 underground coal miners in southern Brazil. This is a cross-sectional study, that detected a low prevalence of depression; light or moderate anxiety in 13% of the workers; self-perception of good health; life quality and good psychological capacity in most of the participants; poor sleep quality in half of them; reverse correlations between anxiety and life quality, and anxiety and psychological capital; positive correlations between psychological capital and life quality; associations between self-perception of health, time, and sleep quality; associations between anxiety and sleep duration and quality; and between alcohol consumption and location at work (front, rear, or variable). The results suggest vulnerabilities regarding anxiety and sleep quality. However, there is a potential coping of determinants that impact on mental health.

Occupational injuries among building construction workers in Addis Ababa, Ethiopia

Background

Occupational injuries can pose direct costs, like suffering, loss of employment, disability and loss of productivity, and indirect costs on families and society. However, there is a dearth of studies clarifying the situation in most of Subsaharan African countries, like Ethiopia. The present study determined the prevalence of injury and associated factors among building construction employees in Addis Ababa, Ethiopia.

Methods

An institutional-based cross-sectional study was conducted among building construction employees in Addis Ababa, Ethiopia from February to April 2015. Multi-stages sampling followed by simple random sampling techniques was used to select the study participants. The sample size of the study was 544. A pre-tested and structured questionnaire was used to collect data. Multivariable analyses were employed to see the effect of explanatory variables on injury.

Results

The prevalence of injury among building construction employees was reported to be 38.3 % [95 % CI: (33.9, 42.7)] in the past 1 year. Use of personal protective equipments, work experience, khat chewing were factors significantly associated with injury.

Conclusion

This is among the few studies describing construction health and safety in Ethiopia. In this study a relatively higher prevalence of injury was reported among building construction employees compared to other studies. If urgent interventions are not in place, the absence from work, loss of productivity and work-related illnesses, disabilities and fatalities will continue to be a major challenge of the construction industry in the future. Therefore, programs to mitigate the burden borne by construction-related injuries should focus on areas, such as provision of safety trainings, promoting use of PPE and monitoring substance abuse in workplace.

Oral Health Status of Underground Coal Mine Workers of Ramakrishnapur, Adilabad District, Telangana, India - A Cross-Sectional Study

INTRODUCTION

Standard of living and quality of life of people has been improved by the expanding industrial activity, but at the other end it has created many occupational hazards. Coal mining is one of the major age old industries throughout the world and in India. Till date very less literature is available worldwide and in India concerning the oral health status of laborers in this field.

AIM

To assess the oral health status of underground coal mine workers, oral hygiene practices, alcohol and tobacco habits.

MATERIALS AND METHODS

A cross-sectional descriptive study was conducted among the underground coal mine workers of a coal mine located in Adilabad district, Telangana, according to the criteria described in the World Health Organization (WHO) Oral Health Assessment form (2013).

STATISTICAL ANALYSIS

Descriptive statistics were done.

RESULTS

A total of 356 workers participated in the study. Ninety percent of the subjects were with tobacco and/or alcohol habits. Dental caries was prevalent in more than half (55.6%) of the study subjects with a mean DMFT of 2.32±2.99. About 48.3% study subjects were with untreated dental caries and 20.3% subjects were with missing teeth. DMFT ≤=6 was seen in 45.5% of subjects and 10.1% have DMFT scores ≥=7. Periodontal disease was the most prevalent condition seen in the population with 94.4% subjects having unhealthy periodontium in terms of gingival bleeding and/or periodontal pockets. About 186 (52.25%) and 145 (40.73%) of subjects were with 0-3mm and 4-5mm loss of attachment respectively. Fourteen percent of population showed dental traumatic injuries.

CONCLUSION

The findings highlighted the high caries prevalence, higher periodontal disease, traumatic injuries which requires immediate intervention.

Epidemiological features of alcohol use in rural India: a population-based cross-sectional study

OBJECTIVES

We sought to estimate the proportion of adults in Sehore District, India, who consumed alcohol, and the proportion who had behaviours consistent with alcohol use disorders (AUDs), using the Alcohol Use Disorders Identification Test (AUDIT). Among men who drank, we identified individual-level, household-level and community-level factors associated with AUDIT scores. Men with AUDs (AUDIT score ≥ 8) reported on whether and where they had sought treatment, and about alcohol-related internal stigma.

DESIGN

Population-based cross-sectional study.

SETTING

Rural villages and urban wards in Sehore District, Madhya Pradesh, India.

PARTICIPANTS

n=3220 adult (≥ 18 years of age) residents of Sehore District.

PRIMARY OUTCOME MEASURE

Score on the AUDIT.

RESULTS

Nearly one in four men (23.8%) had consumed alcohol in the past 12 months, while few (0.6%) women were consumers. Among drinkers, 33.2% (95% CI 28.6% to 38.1%) had AUDIT scores consistent with hazardous drinking, 3.3% (95% CI 2.1% to 5.1%) with harmful drinking and 5.5% (95% CI 3.8% to 8.0%) with dependent drinking. We observed that AUDIT scores varied widely by village (intraclass correlation=0.052). Among men who had recently consumed alcohol, AUDIT scores were positively associated with depression, having at least one child, high-quality housing, urban residence, tobacco use and disability. AUDIT scores were negatively associated with land ownership, out-of-pocket healthcare expenditure and participation in the national employment programme. While 49.2% of men with AUDs felt embarrassed by their problems with alcohol, only 2.8% had sought treatment in the past 12 months.

CONCLUSIONS

A need exists for effectively identifying and treating adults with AUDs. Health promotion services, informed by commonly-expressed stigmatised beliefs held among those affected by AUDs and which are targeted at the most affected communities, may be an effective step in closing the treatment gap.

Associations of Individual-Related and Job-Related Risk Factors with Nonfatal Occupational Injury in the Coal Workers of Shanxi Province: A Cross-Sectional Study

OBJECTIVES

To assess the relationships between the risk factors and the incidence of nonfatal occupational injury of coal mine workers of Shanxi Province.

METHODS

A cross-sectional study was conducted from July 2013 to December 2013, and 4319 workers were recruited from more than 200,000 coal mine employees who are exposed to continuous potential risk of occupational injuries by using a two-stage stratified cluster sampling method. Trained interviewers having necessary medical knowledge conducted face-to-face interviews with the participants. Univariate and multivariable logistic regression models were used to estimate the odds ratio (OR) and the 95% confidence interval (CI).

RESULTS

A total number of 3618 effective respondents were got from 4319 participants (83.77%) and the mean age of the participants was 41.5 years with the standard deviation of 8.65. Significant crude odds ratios were observed for all factors considered except for marital status, education, work duration, BMI, EPQ-RSC(P) scale and EPQ-RSC(L) scale. Results from multivariable logistic regression model showed significant adjusted odds ratios for risk factors including gender (female vs male 0.275, 0.094-0.800), age (≥55 vs ≤25yr 0.169, 0.032-0.900), work type (light physical labor vs heavy physical labor 0.504, 0.328-0.774), workplace (underground auxiliary vs underground front-line 0.595, 0.385-0.919), length of shiftwork experience (0~5yr vs no shift 2.075, 1.287-3.344 and ≥15yr vs no shift 2.076, 1.230-3.504) and EPQ-RSC(E) score (extraversion vs introversion 0.538, 0.334-0.867).

CONCLUSIONS

Several risk factors of nonfatal occupational injury were identified including male, age, heavy physical labor, underground front-line, length of shiftwork experience and introversion. The coal mining enterprises should pay attention to controlling the hazards associated with frontline physical work. Workers' behaviors, life styles and personality traits should also be considered, so that the enterprises could set achievable targets for workers and lessen the exposed period to the risky underground workstation.

Asbestosis: Past voices from the Mumbai factory floor

Background:

Asbestos′s production, processing, and consumption is on very high scale in India and it is increasing, and so do the related diseases. Asbestosis is such a disease which causes progressive respiratory disability.

Aim:

To find out perceptions and thinking about this disease and its risk among the patients which will help in constructing an effective community-based prevention and rehabilitation program.

Materials and Methods:

It was a community-based, qualitative study using a semi-structured interview schedule with 17 asbestosis patients from Mumbai, disgnosed by specialist with pulmonary function test and X-rays as per International Labour Organisation′s recommandations.

Results:

The risk percived by the patients is very less and attitude toward the illness is bengine as there is no clear understanding about the causation. The prolong latent period appears to be the main cause. It suggests a need of very strong program for prevention of asbestosis with the incorporation of worker awareness and eduaction for safety. The socio-economical status and educational levels of the workers make this floating population more vulnarable for manipulation by the corporates.

Conclusion:

Apart from the radical step of ban on asbestos, there is a need of community-based sustainable, affordable, and accessible rehabilitation program with a component of palliative care which will consider the different needs of this marginalized group. The need for such a program is intense as the number of asbestisis patients will keep on increasing till 30 to 40 years of asbestos ban.

Occupational accidents in artisanal mining in Katanga, D.R.C

INTRODUCTION

This study focuses on accidents in artisanal mining, to support policies improving miners' employability.

MATERIALS AND METHODS

Based on a questionnaire administered in November 2009 to a sample of 180 miners from the artisanal mining of LUPOTO, in the Province of Katanga, we explored significant trends between the accidents and their consequences and behavioral or sociological variables.

RESULTS

During the 12 months preceding the study, 392 accidents occurred, affecting 72.2% of miners. Tools handling represents 51.5%, of the accidents' causes, followed by handling heavy loads (32.9%). Factors such as age, seniority or apprenticeship did not generate significant differences. Contusions were the most common injuries (50.2%), followed by wounds (44.4%). These injuries were located in upper limbs (50.5%) and in lower limbs (29.3%). 80.5% of miners were cared for by their colleagues and 50% of them could not work for more than 3 days. Physical sequelae were reported by 19% of the injured miners.

DISCUSSION

Many surveys related to accidents in the area of artisanal mining report such high frequency. The unsuitability of tools to jobs to be done is usually raised as one of the major causes of accidents. The lack of differentiation of the tasks carried out in relation to age is another factor explaining the lack of protective effect of seniority as it minimizes the contribution of experience in the worker's safety. The apprenticeship reported is inadequate; it is rather a learning by doing than anything else. That is why it lacks protective effect. Low income combined with precariousness of artisanal mining are likely to explain the low level of work stoppages.

CONCLUSION

Tools improvement associated with adequate training seem to be the basis of accident prevention. Availability of suitable medical care should improve artisanal miners' recovery after accidents.

Alcohol consumption and work-related injuries among farmers in Heilongjiang Province, People's Republic of China

BACKGROUND

Alcohol consumption has been found to be associated with work-related injuries among workers around the world, but this association has not well been studied among agricultural workers in China.

METHODS

This population-based survey aimed to study the association between alcohol use and work-related agricultural injury. Farmers in a northeastern province of China were questioned about work-related injury in the past year (May 2007-April 2008), alcohol use, farming practices, and sociodemographic factors. The Chi-square test and logistic regression analyses were used to investigate the role of alcohol drinking in agricultural injuries.

RESULTS

Among 2,050 farmers who completed the survey, the 12-month prevalence of work-related injury was 12.2%. The leading external cause of injury was exposure to mechanical force. The odds of injury among farmers with past month drinking, who drank distilled spirits, and reported intoxication were respectively 1.77 (95% CI = 1.27-2.47), 1.89 (95% CI = 1.35-2.66), 2.12 (95% CI = 1.42-3.11). The odds of injury also significantly increased with greater average amounts of pure alcohol per day, with increased frequency of drinking per week, and with greater reported years of drinking. Each alcohol use variable was associated with injury in logistic regression models while controlling for sex, age, years of farm work, months of farm work in the past 12 months, driving a motor vehicle, and agricultural machinery use.

CONCLUSIONS

We found a significant association between alcohol consumption and work-related injuries among farmers. Our findings stress the need for culturally appropriate interventions which affect alcohol use and prevent injuries among Chinese farmers.

Occupational stress among tunnel workers in Sikkim

BACKGROUND

Job stress has been linked to a wide range of adverse effects on mental, physical and organizational health.

OBJECTIVE

The objective of this study was to determine the impact of job stress on mental, physical and social health of the underground construction workers in Sikkim.

MATERIALS AND METHODS

The study population comprised of tunnel workers and a comparable group of controls. Using the interview technique, data was collected using the SF-36 General Health Survey Questionnaire.

RESULTS

The study population comprised of individuals of whom more than half were below 40 years of age and was comparable to the group of controls. Majority reported good health, while poor health was reported by 22 % of the subjects under study Compared to their health status last year, 52% rated their health as somewhat worse. Majority reported that their physical health problems limited them in activities of daily life, viz., running, lifting heavy objects, participation in strenuous sports, climbing several flights of stairs, bending, stooping or kneeling and walking more than a mile, during the past four weeks. More than half of them had severe body ache in the past four weeks that interfered with both work outside home and housework. This was true for emotional problems also, which interfered with their normal social activities involving family, friends, neighbors or groups. The associations of occupational stress with physical, emotional and social life and with limitation of day-to-day activities among tunnel workers were found to be statistically significant.

CONCLUSION

The results emphasize the importance of assessment of the effects of job stress and of fulfilling the need of underground workers for optimum preventive measures.
