Self report of skin problems among farmworkers in North Carolina

BACKGROUND: This study estimates the prevalence of self-reported skin problems among Latino farmworkers and identifies associated risk factors. METHODS: The study used a longitudinal surveillance design. Participants were interviewed up to five times and reported skin problems and personal, work, and environment characteristics. Frequencies and counts were calculated for 13 skin problems. Adjusted odds ratios were obtained for six skin problems. RESULTS: More than one-third of participants reported skin problems, including skin and nail fungus; sunburn; bumps, pimples, or acne; calluses; itching; rash; and insect bite. A variety of work and environment factors were associated with higher rates of skin problems. One of the strongest predictors was working in wet clothes or shoes. CONCLUSIONS: Programs are needed to educate farmworkers about measures they can take to decrease their risk of skin problems. Changes in work practices and personal protective equipment provided could help decrease the prevalence of skin problems.     

Alcohol use among immigrant Latino farmworkers in North Carolina

BACKGROUND: Heavy alcohol use among Latino farmworkers is believed to be common, but it remains poorly documented. METHODS: Interviewer-administered survey questionnaires were administered to 151 Latino male farmworkers in Eastern North Carolina; topics included frequency of alcohol consumption, amount of alcohol typically consumed, frequency of consuming five or more drinks in a single setting, and signs of alcohol abuse/dependence. RESULTS: Over one-quarter (26%) completely abstain from alcohol, but 27% report frequent heavy drinking, or drinking five or more alcoholic beverages two or more times per month. Over one-third of farmworkers (39%) may be alcohol-dependent. Frequent heavy drinking is more common among single farmworkers and among those who do not follow the crops, and dependence is more common among farmworkers living in camps comprised of both H2A and non-contract workers. CONCLUSIONS: There is substantial variation in alcohol use among Latino farmworkers. Although a substantial proportion of farmworkers abstain from alcohol, an equally substantial proportion report alcohol use that poses significant risk for injury on and off the job. More research is needed to document the potential threat to Latino farmworkers by their alcohol use. Interventions targeting alcohol are needed to minimize the risk of injury in an already dangerous occupation.     

Employer Differences in Upper-Body Musculoskeletal Disorders and Pain Among Immigrant Latino Poultry Processing Workers

Between-employer differences in working conditions may lead to variable injury rates. The objective of this paper is to assess the difference in the prevalence of epicondylitis, rotator cuff syndrome, and low back pain among immigrant Latino poultry workers at plants of three different employers. Data were collected from a cross-sectional study among 286 poultry processing workers. Community-based sampling was used to recruit participants in western North Carolina. Rotator cuff syndrome (26.7%) and low back pain (27.9%) were more prevalent among employees of one specific employer. Multivariate analysis showed significant associations of low back pain and rotator cuff syndrome with age, task performed in the processing line, and employer. Employer is a major predictor of musculoskeletal disorders and pain. Line speed and work pace may account for these differences and provide an opportunity for regulation and intervention to protect the health of workers.     

Pterygium among Latino migrant farmworkers in North Carolina

The authors describe the prevalence and severity of pterygium among Latino migrant farmworkers in North Carolina and delineate its risk factors. They selected a sample of 304 farmworkers working in eastern North Carolina in 2005. Digital photographs were taken of each farmworker, including a facial view showing the eyes. Two physicians independently rated each farmworker for the presence and severity of pterygia, with an initial intercoder agreement of 91%. Sixty-eight (23.3%) participants had a pterygium in at least 1 eye; 28 (9.5%) had bilateral pterygia. Age was significantly associated with pterygia (odds ratio = 1.07; 95% confidence interval = 1.03-1.11). Research on the causes of pterygium among farmworkers is needed. In the interim, improvements in farmworkers' preventive behaviors, such as wearing ultraviolet protective lenses and brimmed hats, are reasonable and inexpensive measures.     

Water safety among Latino farmworkers in North Carolina

Latinos constitute the vast majority of North Carolina's farmworker population. Drowning is a significant occupational health hazard in agriculture. Recent reports also suggest a disproportionate number of drowning victims in North Carolina are Latinos. Survey data are used to examine the levels of farmworker participation in aquatic activities and water safety behaviors. Over one-third of the farmworkers reported that they did not know how to swim. About one-quarter of the farmworkers reported participation in aquatic activities, with a greater percentage of those knowing how to swim participating in these activities. Recommendations to increase farmworker water safety include providing information through their employers and health outreach workers.     

Farmworker and nonfarmworker Latino immigrant men in North Carolina have high levels of specific pesticide urinary metabolites

This article compares detections and concentrations of specific organophosphate (OP), bis-dithiocarbamate, and pyrethroid pesticide urinary metabolites among Latino male farmworkers and nonfarmworkers in North Carolina. Data are from interviews and urine samples collected in 2012 and 2013. Farmworkers and nonfarmworkers frequently had detections for OP and pyrethroid pesticide urinary metabolites. Detection of bis-dithiocarbamate urinary metabolites was less frequent, but substantial among the nonfarmworkers. The concentrations of organophosphate, bis-dithiocarbamate, and pyrethroid pesticide urinary metabolites were high for farmworkers and nonfarmworkers compared to National Health and Nutrition Examination Survey results. Pesticide urinary metabolite detection was not associated with occupation in nonfarmworkers. Research for reducing pesticide exposure among farmworkers remains important; research is also needed to determine pesticide exposure pathways among Latino nonfarmworkers.     

Musculoskeletal pain,depression, and stress among Latino manual laborers in North Carolina

The jobs of Latino manual laborers place their mental and physical health at risk. This study evaluates the associations among musculoskeletal pain, mental health, and work organization in Latino manual laborers. Farmworkers and nonfarmworkers (n = 189) in North Carolina were interviewed for self-reported musculoskeletal pain, depressive symptoms, stress, work safety climate, and precarious job status. More nonfarmworkers than farmworkers had neck and shoulder pain, but they did not differ in other areas of musculoskeletal pain. Depressive symptoms had a significant association with neck and shoulder pain (p < .05). Precariousness had a significant association with back pain (p < .05). Farmworker participants had H-2A visas and were afforded some protection compared to nonfarmworker manual workers. Research is needed to improve policy that relieves pain and improves mental health for all Latino manual workers.     

Depressive symptoms and sleepiness among Latino farmworkers in eastern North Carolina

Depression and sleepiness are both risk factors for occupational accidents and unintentional injury. Relatively little is known about the experiences of these risk factors in the immigrant Latino farmworker population. This analysis uses prospective panel data from a sample of Latino farmworkers in eastern North Carolina that were collected at monthly intervals during the 2008 agricultural season to (1) describe depressive symptoms and daytime sleepiness among immigrant Latino farmworkers across the agricultural season; (2) delineate associations of depressive symptoms with sleepiness across time; and (3) determine whether depressive symptoms precede sleepiness, or if sleepiness precedes depressive symptoms. Results indicated that 45% of farmworkers experienced elevated depressive symptoms across the season, whereas 20% experienced elevated sleepiness. Elevated depressive symptoms were more common among farmworkers living in barracks, and less common among those living in trailers. Sleepiness was more common among women than men. There was no evidence that depressive symptoms contributed to sleepiness, or that sleepiness contributed to depressive symptoms. The pattern of results suggests that a substantial proportion of Latino farmworkers experience levels of depressive symptoms or sleepiness that places them at risk for occupational accident or unintentional injury. The results also suggest that depressive symptoms and sleepiness do not cause each other; rather, the association of depressive symptoms with sleepiness hints at the possibility of a common physiologic mechanism such as circadian disruption.

Agriculture and musculoskeletal disorders in low- and middle-income countries

Objectives: To systematically explore and summarize the risk factors of work-related musculoskeletal disorders (WMSDs) among the agricultural workers in low- and middle-income countries (LMIC). In addition, to identify and analyze the methodological flaws in the reviewed studies.

Methods: A comprehensive electronic literature search was conducted using PubMed, Medline, SCOPUS, CINAHL, Science Direct, Embase, Wiley Online Library, Google Scholar, and Web of Science databases. Three-phased screening process was undertaken to eliminate irrelevant publications. Assessment of methodological quality was done using a standardized assessment tool.

Results: Eighteen cross-sectional studies were included in the narrative synthesis. Based on the median score of 38%, nine publications were classified as having higher methodological quality. Eight countries were represented in this review, mainly the South East Asia countries. Majority of the participants were rice farmers. Most common risk factors associated with WMSDs were physical factors (n = 10), followed by individual (n = 6) and psychosocial (n = 5) risk factors. A majority of the studies investigated the risk factors for spinal region. Several methodological weaknesses were noticed in the studies concerning outcome definition, assessment of potential confounders, generalizability, selection bias, information bias, and statistical analysis. Extensive heterogeneity across the studies prevented statistical pooling.

Conclusions: The common anatomical region evaluated was the spine and the most reported risk factors were physical risk factors. Future researches in the LMIC should focus on conducting longitudinal studies that could infer temporality. Researchers should give more attention in defining the study population, evaluating the exposure and outcome in an unbiased way, and in executing reliable statistical analysis.     

Poor safety climate,long work hours,and musculoskeletal discomfort among Latino horse farm workers

This study investigated the prevalence of self-reported musculoskeletal discomfort (MSD) and work-related factors associated with elevated MSD among Latino thoroughbred farm workers. Participants (N = 225) were recruited using a community-based purposive sampling approach to participate in in-person interviews. Of these workers, 85% experienced MSD. MSD was divided into tertiles; the upper tertile was defined as elevated. Multivariable Poisson regression revealed associations between any elevated MSD and longer tenure on horse farms, longer work hours, and poor safety climate. Elevated neck/back MSD was associated with longer tenure, longer work hours, and poor safety climate. Elevated upper extremity MSD was associated with age and poor safety climate. Elevated lower extremity MSD was associated with longer tenure, longer work hours, and being female. Musculoskeletal discomfort is common among these workers. Improving safety climate and minimizing long work hours is recommended.     

Physically demanding workloads and the risks of musculoskeletal disorders in homecare workers in the USA

Although musculoskeletal disorders (MSDs) are prevalent among homecare workers, little is known about the MSD risk factors. This study investigated whether physically demanding workloads among homecare workers are related to MSDs, especially in neck, shoulder and back pain. Data were taken from two waves of a random sample (June to December 2003 and December 2003 to February 2004). The sample included 1643 homecare workers at Wave 1 and 1198 homecare workers at Wave 2, respectively. A basic telephone interview and 30 minutes computer‐assisted interview were performed for homecare workers in Wave 1 and Wave 2. The prevalence of neck, shoulder and back MSDs was assessed at Wave 1 and Wave 2 using the Nordic questionnaire of musculoskeletal symptoms. The incidence of MSDs at 6 months was estimated at Wave 2 using only those who were in the asymptomatic reference group at Wave 1 as the denominator. At Wave 1, back MSDs were the most prevalent (10.2%), followed by neck (9.6%) and shoulder (7.1%) MSDs. After 6 months, the incidence of neck MSDs was the highest (7.0%), followed by back (6.4%) and shoulder (4.8%) MSDs. Physical demands of work were assessed using items developed from focus groups of workers. When compared with asymptomatic workers, those with MSDs showed a dose–response effect for physical job demands. After controlling for age, psychosocial demands and social support on‐the‐job, physical demands among homecare workers were significantly associated with an excessive odds of neck, shoulder and back MSDs incident at 6 months (odds ratios of 1.14–1.17 for each unit increase on a physical demand scale). Our study shows that the physical demands of work are a significant risk factor for MSDs among homecare workers. Considering the high physical demands among homecare workers, the finding in this study clearly indicates that practical intervention strategies should be implemented to protect homecare workers from exposure to MSD risk factors.     

Pesticide exposure beliefs among Latino farmworkers in North Carolina's Christmas tree industry

BACKGROUND: Pesticide exposure is a major preventable occupational hazard for farmworkers. This study examined the beliefs of Latino farmworkers in North Carolina's Christmas tree industry regarding pesticide exposure. METHODS: In-depth interviews were conducted with 20 Mexican male seasonal farmworkers. Participants discussed beliefs about agricultural chemicals, routes of exposure, and health effects of these chemicals. They also discussed their knowledge and use of pesticide safety practices and safety training received. RESULTS: Most farmworkers knew that pesticides could be harmful, though workers varied in their levels of knowledge regarding routes of exposure, specific health effects of pesticides, and ways to avoid and reduce exposure. Workers varied considerably in the amount of safety training received and use of safety practices. Perceived lack of control and health beliefs were salient factors that decreased workers' use of safety practices. CONCLUSIONS: This study adds to the growing body of research which documents the health beliefs of Latino farmworkers in the U.S. relative to pesticides and pesticide safety. This literature is beginning to show convergence on several points (e.g., farmworker knowledge of acute vs. long-term illness resulting from pesticide exposure), as well as regional variation in pesticide safety beliefs. This study substantiates the need for pesticide safety education to address issues of control as well as beliefs.     

Green tobacco sickness and skin integrity among migrant Latino farmworkers

BACKGROUND: Green tobacco sickness (GTS) affects approximately one-quarter of tobacco workers. The primary aim of this analysis is to expand existing knowledge of GTS risk factors by delineating the association of measures of skin integrity with the prevalence of GTS among Latino farmworkers. METHODS: Data are from a longitudinal study of skin disease among 304 North Carolina Latino farmworkers conducted in 2005. RESULTS: 18.4% of the farmworkers met the GTS case definition. Self-reported rash increased the odds of having GTS in the bivariate (OR 2.29, 95% CI 1.21, 4.35), and multivariate analyses (OR 3.30, CI 2.17, 5.02). Self-reported itch (OR 3.54, CI 2.38, 5.24) and superficial wounds (OR 2.49, CI 1.15, 5.39) had a significant relationship to GTS in the bivariate analysis. CONCLUSIONS: These analyses extend current knowledge of GTS risk factors to include skin integrity. Farmworkers with rash and other skin conditions can protect these affected skin areas from exposure to the tobacco plant to reduce their risk of GTS.
