Farm Work–Related Injuries and Risk Factors in South Korean Agriculture

ABSTRACTAgriculture is known to be a risk-filled industry in South Korea, as it is worldwide. The aims of this study were to identify the magnitude of farm work–related injuries and evaluate the association between injury and possible risk factors. Farmers, including farm members (N = 16,160), were surveyed. After excluding 7 subjects with missing data in questions about injury, 16,153 farmer responses were used for the analysis. Of the 16,153 farmers, 3.6% answered having at least one farm work–related injury requiring outpatient treatment or hospitalization during 2012. The proportion of injured men (4.3%) was 1.5 times higher than women (2.9%). From an age perspective, the proportion was 1.3% of those aged 49 or below, 2.7% of those aged 50–59, 4.2% of those aged 60–69, 4.2% of those aged 70–79, and 3.1% of those aged 80 or above. We used a multivariate logistic regression analysis with a stepwise model (forward) for risk factors (gender, age, farm ownership, farm type, work years in agriculture, work months during 2012, night work experience, and work experience under the influence of alcohol). The increased risk of farm work–related injuries significantly remained associated with age, farm ownership, and experience of night work. Further studies should be conducted to consistently identify injury characteristics, especially for old farmers, considering the crop cultivation in Asian countries.

Agricultural injury risk among rural California public high school students: Prospective results

To characterize prospective agricultural injury experience among rural California Central Valley public high school students enrolled in agricultural sciences curriculum. The University of California, Davis Youth Agricultural Injury Study (UCD-YAIS) examined prospective farm-work injury among students from 10 California Central Valley public high schools. Of eligible subjects, 882 (62.5%) completed at least one annual follow-up survey. Of these, 489 reported farm work in the previous year, including 40 (8.2%) with at least one farm work-related injury. Fractures were the most common injury, especially among girls. Girls were more likely to suffer animal-related injury and boys injury from motor vehicles, machinery, or tool use. Prospective injury risk was strongly associated with prior-year farm injury (OR 8.53; 95% CI 4.02, 18.1) and farm work hours. After adjustment for farm work hours, grade level, and sex, risk was significantly associated with machinery operation, applying chemicals, number of hazardous tasks performed, riding motorcycles or mopeds, riding in back of an uncovered pick-up truck, and smoking. Risky attitude toward farm safety was associated prospectively with injury in stepwise fashion. Adolescents are at risk for serious farm-work injuries. Although limitations on hazardous tasks and farm work hours are likely to be the most efficacious means for reducing injury, education will play an important role. Education should include inculcating safety-related attitudes and habits and focus on hazardous tasks, such as those involving animals (for girls) and motor vehicles and machinery (for boys), especially among youth with prior farm injury.

Agricultural injury among rural California public high school students

The University of California, Davis Youth Agricultural Injury Study characterized the farm work and agricultural injury experience among rural California Central Valley public high school students enrolled in an agricultural sciences curriculum. We conducted a cross-sectional survey of agricultural injury among students from 10 California Central Valley high schools during the 2001-2005 school years. Of 1,783 subjects, 946 (53.1%) reported farm work in the previous year, including 97 (10.3%) reporting at least one farm work-related injury in the preceding year. After adjustment for sex, ethnicity, and hours spent in farm work, injury risk was associated with large-animal operations (OR 4.15; 95%CI: 1.18, 14.65), feeding large animals (OR 2.38; 95%CI: 1.15, 4.96), mixing chemicals (OR 1.86; 95%CI: 1.15, 3.03), welding (OR 2.09; 95%CI: 1.17, 3.72), non-use of seatbelts, and frequent riding in the back of an uncovered pick-up truck. Risky attitudes toward farm safety were significantly associated with injury. Girls were more likely to suffer an animal-related injury and boys to suffer injury related to motor vehicles, machinery, or tool use. Adolescents are at similar risk to adults for agricultural injury. Although limitations on hazardous tasks and time spent on farm work are likely to be the most efficacious means for reducing injury, education will play an important role. Educational measures should include inculcating healthy safety-related attitudes and focus on hazardous tasks, such as those involving animals (for girls) and motor vehicles and machinery (for boys).

Farmwork-Related Injury Among Farmers 50 Years of Age and Older in Kentucky and South Carolina: A Cohort Study, 2002-2005

Farmers in the U.S. are becoming more diverse; the average age of the farmer is increasing, as is the number of women and minority farm operators. There is limited research on injury risk factors in these special populations of farmers. It is especially important to study the risk factors for injury in these growing and at-risk groups. A longitudinal survey was conducted of farmers (n = 1,394) age 50 and older who resided in Kentucky and South Carolina. The questionnaire was administered by telephone and mail surveys four times between 2002 and 2005 to the fixed cohort of farmers, obtained by convenience sample. Approximately half of the cohort was female, and the majority of the cohort worked less than 40 hours per week. This cohort reported a crude, non-fatal injury rate of 9.3 injured farmers per 100 per year. Farmers reporting chronic bronchitis/emphysema (estimated odds ratio [EOR] = 1.57), back problems (EOR = 1.37), arthritis (EOR = 1.31), 3 to 4 restless nights in the past week (EOR = 2.02), or 5 to 7 restless nights in the past week (EOR = 1.82) were at significantly higher odds of sustaining a farmwork-related injury as calculated by the generalized estimating equations (GEE) regression method Farmers operating equipment on highways (EOR = 1.51) or climbing higher than eight feet (EOR = 1.69) were at significantly higher odds of sustaining a farmwork-related injury, and females were at higher risk of injury when performing animal-related tasks (EOR = 3.00) or crop-related tasks (EOR = 2.21). Identified factors associated with farmwork-related injury should better inform agricultural health policies and guidelines for older farmers, such as policies governing the allowable number of hours worked per week and rest breaks, guidelines that advise appropriate types of farm tasks, and ergonomic engineering advances on farming equipment.

Safety knowledge, safety behaviors, depression, and injuries in Colorado farm residents

Changing safety behavior has been the target of injury prevention in the farming community for years but significant reductions in the number of farming injuries have not always followed. This study describes the relationships between safety knowledge, safety behavior, depression, and injuries using 3 years of self-reported data from a cohort of farm residents in Colorado. Farm operators and their spouses (n = 652) were recruited in 1993 from a farm truck registration list using stratified probability sampling. Respondents answered ten safety knowledge and ten safety behavior questions. The Center for Epidemiologic Studies-Depression (CES-D) scale was used to evaluate depression. The most severe farm work-related injury over a 3-year period was the outcome variable. Factor analysis was used to produce a single measure of safety knowledge for logistic regression models to evaluate the relationships between injuries, safety knowledge, and behaviors. Safety knowledge was significantly associated with wearing personal protective equipment. None of the safety behaviors were significantly associated with injuries. In the presence of depression, low safety knowledge increased the probability of injury (OR 3.87, 95% CI 1.00-15.0) in models adjusted for age, sex, hours worked per week, and financial problems. Compared to those not depressed, those depressed with a low safety score showed significantly greater risk of injury than those depressed with a high score in adjusted models (OR 3.09, CI 1.31-7.29 vs. OR 0.86, CI 0.31-2.37). Future work on injuries in the farming community should include measures of mood disorders and interactions with safety perceptions and knowledge.

Exposure Risks and Tetanus Immunization Status in Farmers Ages 50 and Over

Despite an effective tetanus vaccine, tetanus continues to claim lives worldwide. The very young and the elderly are at highest risk for the disease. Farmers are at high risk for injury, the leading factor associated with tetanus. As part of a larger study of older members of farm households in the southern United States, 595 participants provided data on health, injuries, work, socioeconomic status, and healthcare. 69% reported receiving a tetanus booster in the past ten years, 24% had not, and 7% did not know. Females were less likely to be currently immunized. There was no association between immunization status and age, income, or race. There were associations between farm tasks, farm work-related injury, and immunization. Older farmers are at risk for tetanus by virtue of their age and work environment. Health care providers should explore strategies to improve immunization status among this work group.

Farm Work-Related Injury among Middle School Students in Rural China

Farm work-related injuries are considered an important issue facing rural area adolescents. However, little research has been done in developing countries, including China. This study evaluated agricultural work-related injuries among Chinese middle school adolescents, focusing on the potential association between farm work hours, sleep patterns, school-related stress, and farm work-related injuries. This cross-sectional study surveyed 1,551 middle school students in Hunan Province who reported working on farms. The surveys assessed their involvement in farm work, sleep patterns, school activities, and farm work-related injuries during a three-month recall period. The cumulative incidence of farm work-related injury was 15.6% among the 1187 students who reported working on a farm. Average days per month farming, number of pesticide applications per month, sleep disturbances, and school-related stress were significantly associated with farm work-related injuries (p < 0.05). Multivariable logistic regression analysis revealed that after adjusting for possible confounding effects of age, gender, and farm work days per month, sleep disturbance (less than 7 hours of sleep: OR = 2.36, 95% CI = 1.07-5.22; awakening at night and having trouble falling back to sleep: OR = 2.70, 95% CI = 1.36-5.37; having nightmares: OR = 2.24, 95% CI = 1.18-4.24) and school-related stress (difficult homework: OR = 2.45, 95% CI = 1.21-4.99; extra homework assigned often by parents: OR = 3.62, 95% CI = 1.88-6.97; and scolded/chastised by parents for poor school performance: OR = 2.53, 95% CI = 1.75-3.65) were statistically significant risk factors for farm work-related injuries (p < 0.05).

Health Risk Behaviors and Work Injury Among Hispanic Adolescents and Farmworkers

Adolescents may engage in health risk behaviors that increase their likelihood of injury. Employment places adolescents at risk of work-related injuries. This study responds to the paucity of data on the relationship between adolescent health risk behaviors and work-related injury. This cross-sectional study included the administration of anonymous surveys to ninth graders (n=4914) who attended high schools in south Texas. An aggregate risk score (ARS) was developed based on health risk behaviors. The ARS was analyzed as an outcome using linear regression. Associations between health risk behaviors and work-related injury were assessed with logistic regression. Of the respondents, 19% reported they had a job, and 14% reported that they had been employed in farmwork. Farmwork-related injury was reported by 9% of adolescents, and 12% reported other work-related injury. Mean ARS scores were significantly higher (p < 0.05) for both male and female adolescents who reported a work-related injury compared to nonworking adolescents, and for males who had done migrant farmwork compared to all other adolescent males. The ARS increased as hours worked per week increased. After controlling for confounding factors, a statistically significant association was found between ARS and non-farmwork, work-related injury, but not between ARS and farmwork-related injury. Farmworkers with high ARS were more likely to report non-farmwork, work-related injuries. The predictors of work-related injury in the adolescent groups, particularly for farmworkers and migrants who are under additional stress, remain an important occupational health area to be addressed.

Risk Factors for Low Back Injury Among Farmers in Iowa: A Case-Control Study Nested in the Agricultural Health Study

The aim of this study was to assess risk factors for low back injury requiring medical advice or treatment among Iowa farmers. Although farmers are at risk for low back injury, few studies have addressed risk factors for farm work-related low back injury. We screened 6999 participants in the Iowa portion of the Agricultural Health Study to identify 49 male farmers who reported farm work-related low back injury requiring medical advice or treatment in the previous year. We compared them with 465 uninjured male farmer controls. Multivariable modeling identified four risk factors significantly associated with low back injury: age less than 45 years (OR = 3.32; 95% CI 1.75–6.20), doctor-diagnosed asthma (OR = 4.26; 95% CI 1.49–12.10), education beyond high school (OR = 2.12; 95% CI 1.13–3.90), and difficulty hearing normal conversation (even with a hearing aid, in the case of those using one) (OR = 1.98; 95% CI 1.02–3.80). Although hearing difficulty may be a general risk factor for occupational injury, asthma may be a more specific risk factor for low back injury. Future research to assess the risk factors, asthma and difficulty hearing, may be particularly important, since farmers are at increased risk for hearing loss, and farmers come into contact with many inhaled agents that can cause asthma.

Challenges of Recruiting Farm Injury Study Participants through Hospital Emergency Departments

Background: Hospital emergency departments are common recruitment sites for injury studies. Yet recruitment method details, capture rates and response fractions are not consistently reported. As privacy legislation increasingly impinges on research activity, these parameters become even more important. The authors describe their experience with recruitment via emergency departments and outline subsequent adjustments to the recruitment approach. Methods: The FIRM study was an Australian case-control study of serious farm work-related injury. Cases were identified prospectively by hospital staff on presentation to emergency departments. Consistent with the Victorian Health Records Act, potential cases were initially approached by hospital staff, and full recruitment was subsequently undertaken by study staff. Manual hospital record audits were conducted at five recruitment sites to determine the proportion of eligible cases approached. Results: Among 660 medical records audited, 19 eligible cases were confirmed, 9 of whom were approached by hospital staff (47%, 95% CI 25 to 70%). In response, an additional process was established to capture missed cases, who were sent a letter from the hospital providing the opportunity to opt out of telephone contact by study staff. Early indications were that 34% (41/122) of missed cases actively declined to be contacted. Among those who were contacted and eligible, 84% (21/25) agree to study participation. Conclusions: Recruitment of injury research participants via hospital emergency departments is challenging, particularly where authorities require an intermediary to make the initial contact. Removal of some constraints imposed by privacy legislation would considerably simplify recruitment and enhance scientific rigour in conducting epidemiological research.

Minimizing Bias in a Case-Control Study of Farm Injury

We report on our strategies to minimize bias in the FIRM study, a prospective case-control study of risk factors for serious farmwork-related injury. The study base is adult males working on farms in the catchment regions of 14 larger regional hospitals in one Australian state. Cases are identified on presentation to the emergency departments, while age-matched controls are recruited via random telephone survey. Eligibility criteria for cases include a maximum abbreviated injury severity score of at least 2, to minimize the potential for selection bias against those with less severe injuries treated outside the hospital system. An audit at one hospital showed that 93% of eligible patients identified in the electronic surveillance system had been approached regarding participation. Results to date show that 38% of those approached decline to have their contact details made available to researchers. Those who decline are asked to complete two key questions to enable comparison with those who participate. Control recruitment relies on telephoning regional households until an individual from the study base, satisfying the matching criteria, is identified. This process minimizes the potential for selecting against farm workers who may live off-farm. Ninety-four percent of age-matched eligible controls have participated to date. We are testing a dynamic pool of individuals identified as study base members but not matched on the first call to determine its effect on the probabilities of selection. Our strategies appear to be minimizing detection, selection, and response bias, thereby enhancing the validity of the study results.

Alcohol consumption patterns and work-related injuries among Colorado farm residents

Background Few studies have assessed the relationship between alcohol consumption patterns among farm populations and work-related injuries. The purpose of this study was to assess the role of alcohol consumption patterns on farmwork-related injuries. Methods Prospective cohort study of Colorado farm residents, 1993 to 1995. Self-reported injuries, alcohol consumption, and demographics were assessed over 3 years. A stratified probability sample of farms was selected to include approximately 2.6% of Colorado farm residences with a farm operator living on the property. A total of 485 farms, including 872 individuals, were recruited in the initial cohort. In the second year, 746 individuals were re-interviewed, and in the third year, 653 of the original group participated. Results Injuries during the study period were assessed in relationship to alcohol consumption. During the 3 years, 150 farm residents reported a total of 215 farmwork-related injuries. An increased risk of injury was associated with increased alcohol consumption. Compared to abstainers, farm residents who drank more frequently had higher farmwork injury incidence rates (3.09 and 3.35 injuries per 10,000 person-days of observation versus 1.94 injuries per 10,000). Farm residents who typically drank three or more drinks per day had a farmwork injury rate of 3.62 per 10,000 person-days (95% confidence interval [CI]=2.38–4.85). Farm residents who typically drank one to two drinks per day had a farmwork-related injury rate of 3.02 per 10,000 person-days (95% CI=2.44–3.60). In multivariate models, alcohol consumption frequency and quantity were significantly associated with farmwork-related injuries. Conclusions Alcohol consumption should be considered in studies of agricultural injuries.

Risk factors for agricultural injury: a case-control analysis of Iowa farmers in the Agricultural Health Study.

The purpose of this case-control study nested in the Agricultural Health Study was to assess risk factors for agricultural injury among a large group of Iowa farmers. A questionnaire sent to 6,999 farmers identified 431 cases who had a farm work-related injury requiring medical advice/treatment in the previous year and 473 controls who had no injury in the previous year. We assessed several potential risk factors for injury. A multiple logistic regression analysis showed significant associations between farm work-related injury and weekly farming work hours (> or = 50 hours/week) (OR = 1.65; 95% CI = 1.23-2.21), the presence of large livestock (OR = 1.77; 95% CI = 1.24-2.51), education beyond high school (OR = 1.61; 95% CI = 1.21-2.12), regular medication use (OR = 1.44; 95% CI = 1.04-1.96), wearing a hearing aid (OR = 2.36; 95% CI = 1.07-5.20), and younger age. These results confirm the importance of risk factors identified in previous analytic studies and suggest directions for future research in preventive intervention strategies to reduce farm work-related injuries.

Risk Factors for Work-Related Injury Among Male Farmers in Iowa: A Prospective Cohort Study

Agriculture is one of the most hazardous occupations in the United States. We examined the work-related injury rate and risk factors among 290 Iowa male principal farm operators using a population-based, prospective study. Baseline data were collected between 1991 and 1994, and injury events were surveyed in the fall of 1995. Cumulative incidence of farmwork-related injury during the previous year was 10.5%. We found that depressive symptoms (odds ratio, 3.22; 95% confidence interval, 1.04 to 9.99) and the number of hours working with animals (odds ratio, 2.14; 95% confidence interval, 1.04 to 4.44) were associated with the incidence of farmwork-related injuries.
