Risk Factors for Agricultural Injury: A Systematic Review and Meta-analysis

ABSTRACT The objective of this study was to identify significant risk factors for agricultural injury based on the literature. The authors conducted a systematic review of commonly reported risk factors. Studies that reported adjusted odds ratio (OR) or relative risk (RR) estimates for the selected risk factors were identified from PubMed and Google Scholar. Pooled risk factor estimates were calculated using meta-analysis. A total of 441 (PubMed) and 285 (Google Scholar) studies were found in the initial searches; of these, 132 and 78 studies, respectively, met the selection criteria for injury outcomes, and 32 of these reported adjusted OR or RR estimates. One study was excluded because it did not meet the set Newcastle-Ottawa Scale quality criteria. Finally, 31 studies were used for meta-analysis. The pooled ORs for the risk factors were as follows: male gender (vs. female) 1.68, full-time farmer (vs. part-time) 2.17, owner/operator (vs. family member or hired worker) 1.64, regular medication use (vs. no regular medication use) 1.57, prior injury (vs. no prior injury) 1.75, health problems (vs. no health problems) 1.21, stress or depression (vs. no stress or depression) 1.86, and hearing loss (vs. no hearing loss) 2.01. All selected factors except health problems significantly increased the risk of injury, and they should be (a) considered when selecting high-risk populations for interventions, and (b) considered as potential confounders in intervention studies.

Review and Meta-analysis of Emerging Risk Factors for Agricultural Injury.

ABSTRACT Agricultural injury is a significant public health problem globally. Extensive research has addressed this problem, and a growing number of risk factors have been reported. The authors evaluated the evidence for frequently reported risk factors earlier. The objective in the current study was to identify emerging risk factors for agricultural injury and calculate pooled estimates for factors that were assessed in two or more studies. A total of 441 (PubMed) and 285 (Google Scholar) studies were identified focusing on occupational injuries in agriculture. From these, 39 studies reported point estimates of risk factors for injury; 38 of them passed the Newcastle-Ottawa criteria for quality and were selected for the systematic review and meta-analysis. Several risk factors were significantly associated with injury in the meta-analysis. These included older age (vs. younger), education up to high school or higher (vs. lower), non-Caucasian race (vs. Caucasian), Finnish language (vs. Swedish), residence on-farm (vs. off-farm), sleeping less than 7–7.5 hours (vs. more), high perceived injury risk (vs. low), challenging social conditions (vs. normal), greater farm sales, size, income, and number of employees on the farm (vs. smaller), animal production (vs. other production), unsafe practices conducted (vs. not), computer use (vs. not), dermal exposure to pesticides and/or chemicals (vs. not), high cooperation between farms (vs. not), and machinery condition fair/poor (vs. excellent/good). Eighteen of the 25 risk factors were significant in the meta-analysis. The identified risk factors should be considered when designing interventions and selecting populations at high risk of injury.

Estimates of community exposure and health risk to sulfur dioxide from power plant emissions using short-term mobile and stationary ambient air monitoring.

To estimate plausible health effects associated with peak sulfur dioxide (SO2) levels from three coal-fired power plants in the Baltimore, Maryland, area, air monitoring was conducted between June and September 2013. Historically, the summer months are periods when emissions are highest. Monitoring included a 5-day mobile and a subsequent 61-day stationary monitoring study. In the stationary monitoring study, equipment was set up at four sites where models predicted and mobile monitoring data measured the highest average concentrations of SO2. Continuous monitors recorded ambient concentrations each minute. The 1-min data were used to calculate 5-min and 1-hr moving averages for comparison with concentrations from clinical studies that elicited lung function decrement and respiratory symptoms among asthmatics. Maximum daily 5-min moving average concentrations from the mobile monitoring study ranged from 70 to 84 ppb (183–220 µg/m3), and maximum daily 1-hr moving average concentrations from the mobile monitoring study ranged from 15 to 24 ppb (39–63 µg/m3). Maximum 5-min moving average concentrations from stationary monitoring ranged from 39 to 229 ppb (102–600 µg/m3), and maximum daily 1-hr average concentrations ranged from 15 to 134 ppb (40–351 µg/m3). Estimated exposure concentrations measured in the vicinity of monitors were below the lowest levels that have demonstrated respiratory symptoms in human clinical studies for healthy exercising asthmatics. Based on 5-min and 1-hr monitoring, the exposure levels of SO2 in the vicinity of the C.P. Crane, Brandon Shores, and H.A. Wagner power plants were not likely to elicit respiratory symptoms in healthy asthmatics. Implications: Mobile and stationary air monitoring for SO2 were conducted to quantify short-term exposure risk, to the surrounding community, from peak emissions of three coal-fired power plants in the Baltimore area. Concentrations were typically low, with only a few 5-min averages higher than levels indicated during clinical trials to induce changes in lung capacity for healthy asthmatics engaged in exercise outdoors.

Pesticide use practices in rural Armenia.

ABSTRACT Pesticide use can have adverse effects on both human health and the environment. Inappropriate use of pesticides increases the health risk to those who work with or live around pesticides. Educational programs for agricultural workers on the proper use of pesticides and personal protective equipment coupled with pesticide regulations are important tools to reduce the associated health risks. The authors conducted a survey (N = 2336) on pesticide use practices in the Ararat Valley of Armenia in 2000–2006. This study was a cross-sectional design. A multistage sampling method was implemented in the selection of the study population. The authors developed a questionnaire containing 173 questions to evaluate demographic characteristics, health conditions, and details of pesticides use practices. The intensity of pesticide use was high; 82.8% of respondents used them. More than 150 brand names of pesticides were in use. Unregistered, obsolete, expired, and banned compounds were found in active use. Poor compliance with the basic rules of pesticide safety was found throughout the study population, with 21.3% using gloves and only 11% using respirators. The agricultural workers’ knowledge of the toxic properties of these pesticides as well as basic hygienic norms was very low. In some instances, the number of agrichemical applications to crops, particularly cucumbers and melons, reached 40 applications during the growing season. Better protection and training of pesticide users in Armenia is needed.

Social Marketing Campaign Promoting the Use of Respiratory Protection Devices Among Farmers

ABSTRACT This article describes the formal use of marketing concepts in a systematic approach to influence farmers to voluntarily increase respiratory protective device (RPD) use. The planning process for the project incorporated six key decision or action points, each informed by formative research or health behavior theory. The planning process included developing behavior change strategies based on a 4P model (product, price, place, and promotion). The resulting campaign elements included print and e-mail messages that leveraged motivators related to family and health in order to increase farmers’ knowledge about the risks of exposure to dusty environments, four instructional videos related to the primary barriers identified in using RPDs, and a brightly colored storage bag to address barriers to using RPDs related to mask storage. Campaign implementation included a series of e-mails using a bulk e-mail subscription service, use of social media in the form of posting instructional videos on a YouTube channel, and in-person interactions with members of the target audience at farm shows throughout the Central States Center for Agricultural Safety and Health seven-state region. Evaluation of the e-mail campaigns indicated increased knowledge about RPD use and intent to use RPDs in dusty conditions. YouTube analytic data indicated continuing exposure of the instructional videos beyond the life of the campaign. The project demonstrates the efficacy of a planning process that incorporates formative research and clear decision points throughout. This process could be used to plan health behavior change interventions to address other agriculture-related health and safety issues.

The Association of Sleep Loss and Balance Stability in Farmers

ABSTRACT Sleep deprivation has been linked to injuries, illnesses, and reduced performance measures. Yet, it is unclear how sleep loss contributes to the high rates of injuries and falls in agriculture. In this study, the authors evaluated sleep loss and quantified its association with balance in five farmers, who wore an ActiWatch to record their sleeping patterns in six repeated weekly observation periods. Acute sleep loss was computed as the net sleep (sleeping hours the night before balance testing − average sleep hours during the week). All farmers performed four balance tests on either one foot or both feet and with eyes open or closed. Balance was measured using a pressure mat to monitor the change in center of pressure (CoP) of the feet in anteroposterior (AP) and mediolateral (ML) directions. Spearman’s rank correlation coefficient indicated balance outcomes were strongly and negatively correlated with the net sleep (P < .05). As the net sleep decreased, farmers became less stable, particularly indicated by an increase in the area, total displacement, and deviations of CoP in both AP and ML directions while standing on both feet with eyes open. Fisher’s exact test showed an association between the CoP in AP direction and the net sleep (P = .020, odds ratio [OR] = 7.37). Thus, the odds of having reduced balance stability were 7.4 times higher when farmers slept less than their average hours during the night prior to the balance test. These results suggest that acute sleep loss impacts balance stability that may lead to falls. Understanding the association of sleep loss and balance stability is important in prevention of agricultural injuries.

Occupational Health and Safety of Finnish Dairy Farmers Using Automatic Milking Systems

Introduction Conventional pipeline and parlor milking expose dairy farmers and workers to adverse health outcomes. In recent years, automatic milking systems (AMS) have gained much popularity in Finland, but the changes in working conditions when changing to AMS are not well known. The aim of this study was to investigate the occupational health and safety risks in using AMS, compared to conventional milking systems (CMS). Methods An anonymous online survey was sent to each Finnish dairy farm with an AMS in 2014. Only those dairy farmers with prior work experience in CMS were included in the final analysis consisting of frequency distributions and descriptive statistics. Results We received 228 usable responses (131 male and 97 female; 25.2% response rate). The majority of the participants found that AMS had brought flexibility to the organization of farm work, and it had increased leisure time, quality of life, productivity of dairy work, and the attractiveness of dairy farming among the younger generation. In addition, AMS reduced the perceived physical strain on the musculoskeletal system as well as the risk of occupational injuries and diseases, compared to CMS. However, working in close proximity to the cattle, particularly training of heifers to use the AMS, was regarded as a high-risk work task. In addition, the daily cleaning of the AMS and manual handling of rejected milk were regarded as physically demanding. The majority of the participants stated that mental stress caused by the monotonous, repetitive, paced, and hurried work had declined after changing to AMS. However, many indicated increased mental stress because of the demanding management of the AMS. Nightly alarms caused by the AMS, lack of adequately skilled hired labor or farm relief workers, and the 24/7 standby for the AMS were issues that also caused mental stress. Conclusion Based on this study, AMS may have significant potential in the prevention of adverse health outcomes in milking of dairy cows. In addition, AMS may improve the productivity of dairy work and sustainability of dairy production. However, certain characteristics of the AMS require further attention with regard to occupational health and safety risks.

Predictors for occupational injuries and diseases among commercial fishers in Finland 1996–2015

Fishing is a hazardous occupation worldwide. Commercial fishers in Finland are an aging and diminishing population with a high injury rate. Insurance claims data for self-employed Finnish commercial fishers during the years 1996 through 2015 (n = 1951) were analysed to assess predictors for occupational injuries and diseases. Out of the available variables, fishery location, career length, and participation in the voluntary occupational health service programme were not significant predictors. Male gender (OR 2.02; 95% CI 1.37-2.99), Finnish mother tongue vs. Swedish (OR 1.98, 95% CI 1.53-2.55), and higher income levels from fishing (four income categories, OR range: 1.71-3.53) were associated with higher odds for a compensated occupational injury or disease claim among commercial fishers in the final multivariate model. The identified risk groups could be targeted for interventions, and the content of the occupational health service programme should be developed to gain protective effect.

Development of a Safety Management Web Tool for Horse Stables

Simple Summary A new web tool for equine activities, InnoHorse, was developed to support horse stable managers in business, safety, pasture and manure management. The aim of the safety section of the web tool was to raise awareness of safety issues in daily horse stable activities. This section contains a safety checklist, stable safety map and good practices to support human health and horse welfare and to prevent injuries in horse-related activities. Reviews of the literature and statistics, empirical horse stable case studies, expert panel workshops and stakeholder interviews were utilized in designing the web tool. Abstract Managing a horse stable involves risks, which can have serious consequences for the stable, employees, clients, visitors and horses. Existing industrial or farm production risk management tools are not directly applicable to horse stables and they need to be adapted for use by managers of different types of stables. As a part of the InnoEquine project, an innovative web tool, InnoHorse, was developed to support horse stable managers in business, safety, pasture and manure management. A literature review, empirical horse stable case studies, expert panel workshops and stakeholder interviews were carried out to support the design. The InnoHorse web tool includes a safety section containing a horse stable safety map, stable safety checklists, and examples of good practices in stable safety, horse handling and rescue planning. This new horse stable safety management tool can also help in organizing work processes in horse stables in general.

Finland: Occupational accidents and safety work in the Finnish fishery - Developments and preventive measures

The study is based on a combination of previous research and historical initiatives taken by authorities in the respective Nordic countries to promote safety in fisheries. So far there has been limited knowledge about what has worked and has positively influenced the rate and severity of occupational accidents, and fishermens own experiences with prevention has not been studied. Therefore, the project has been supplemented with a joint Nordic investigation of fishermen, focusing on the accumulation of the fishermen’s experience regarding actions that have played a preventive role in terms of occupational accidents in fisheries. On this basis, the results of the study have been summarised. Possible explanations for the significant reduction in the work accidents highlighted by the report, and recommendations for dissemination of the results of the project have been outlined.
