Heat-Related Illness among Oregon Farmworkers

Farmworkers are particularly vulnerable to climate-sensitive health outcomes such as heat-related illness (HRI) given their tasks involve heavy exertion in an outdoor setting. The objectives of the study were to: (1) describe symptoms of HRI experienced by farmworkers and (2) explore factors associated with heat knowledge, level of concern regarding HRI, and comfort level taking breaks at work. Bilingual research staff conducted personal interviews of 100 farmworkers during July and August 2013. Data collected included demographics, work history and current work practices, trainings received, HRI symptoms experienced, health status, and health behaviors. Nearly 30% of participants reported experiencing ≥2 HRI symptoms during the previous work. Few participants had high level of heat knowledge (21.0%) and 15.6% of participants reported being "very concerned" about the health effects of working in hot conditions. Participants who were paid by the piece were more likely to have a high heat knowledge score and be "very concerned" about HRI but less likely to be "very comfortable" taking a break compared to workers paid by the hour than those who had not received HRI training. Results suggest several areas in which employers and agencies conducting outreach and education to the workers about HRI can change their practices including providing cooling measures and HRI training about risk factors for HRI.Keywords: Farmworker, Heat-related illness, Latino, Migrant healt

Assessing Disaster Preparedness among Latino Migrant and Seasonal Farmworkers in Eastern North Carolina

Natural disasters including hurricanes, floods, earthquakes, tornadoes, and fires often involve substantial physical and mental impacts on affected populations and thus are public health priorities. Limited research shows that vulnerable populations such as the low-income, socially isolated migrant and seasonal farmworkers (MSFW) are particularly susceptible to the effects of natural disasters. This research project assessed the awareness, perceived risk, and practices regarding disaster preparedness and response resources and identified barriers to utilization of community and government services during or after a natural disaster among Latino MSFWs’ and their families. Qualitative (N = 21) focus groups (3) and quantitative (N = 57) survey methodology was implemented with Latino MSFWs temporarily residing in rural eastern North Carolina to assess perceived and actual risk for natural disasters. Hurricanes were a top concern among the sample population, many participants shared they lacked proper resources for an emergency (no emergency kit in the house, no evacuation plan, no home internet, a lack of knowledge of what should be included in an emergency kit, etc.). Transportation and language were found to be additional barriers. Emergency broadcasts in Spanish and text message alerts were identified by the population to be helpful for disaster alerts. FEMA, American Red Cross, local schools and the migrant clinic were trusted places for assistance and information. In summary, tailored materials, emergency alerts, text messages, and news coverage concerning disaster threats should be provided in the population’s native language and when feasible delivered in a culturally appropriate mechanism such as “charlas” (talks) and brochures.Keywords: disaster preparedness, MSFW, Latino migrant and seasonal farmworker

Stress, Depression and Coping among Latino Migrant and Seasonal Farmworkers

Research shows that one in four migrant farmworkers experienced an episode of one or more mental health disorders such as stress, depression, or anxiety in their lifetime. The purpose of this mixed methods study was to explore experiences and perceptions related to stress and depression among Latino migrant and seasonal farmworkers (MSFWs), and to identify their coping behaviors for dealing with these mental health conditions. Using a mixed methods research approach, three focus group interviews of a sample of Latino MSFWs (N = 29) were conducted and a quantitative survey was implemented (N = 57) at community sites in eastern North Carolina. Four major themes emerged from the focus group data: (1) physical stress related to working conditions; (2) mental stress related to family situations, work environment, documentation status, and lack of resources; (3) depression related to separation from family and the lack of resources; and (4) use of positive and negative mechanisms for coping with stress and depression. A discussion of these themes, results from the survey findings, implications for intervention and outreach programs, along with recommendations for further research, are provided.Keywords: Migrant and seasonal farmworkers, Depression, Stress, Coping, Latin

Commute Times, Food Retail Gaps, and Body Mass Index in North Carolina Counties

Introduction: The prevalence of obesity is higher in rural than in urban areas of the United States, for reasons that are not well understood. We examined correlations between percentage of rural residents, commute times, food retail gap per capita, and body mass index (BMI) among North Carolina residents. Methods: We used 2000 census data to determine each county\u27s percentage of rural residents and 1990 and 2000 census data to obtain mean county-level commute times. We obtained county-level food retail gap per capita, defined as the difference between county-level food demand and county-level food sales in 2008, from the North Carolina Department of Commerce, and BMI data from the 2007 North Carolina Behavioral Risk Factor Surveillance System. To examine county-level associations between BMI and percentage of rural residents, commute times, and food retail gap per capita, we used Pearson correlation coefficients. To examine cross-sectional associations between individual-level BMI (n=9,375) and county-level commute times and food retail gap per capita, we used multilevel regression models. Results: The percentage of rural residents was positively correlated with commute times, food retail gaps, and county-level BMI. Individual-level BMI was positively associated with county-level commute times and food retail gaps. Conclusions: Longer commute times and greater retail gaps may contribute to the rural obesity disparity. Future research should examine these relationships longitudinally and should test community-level obesity prevention

Utility of a Work Process Classification System for characterizing non-fatal injuries in the Alaskan commercial fishing industry

Background. The US commercial fishing industry is hazardous, as measured by mortality data. However, research on non-fatal injuries is limited. Non-fatal injuries constitute the majority of occupational injuries and can result in workers' lowered productivity and wages, lost quality of life, and disability. In the United States, a Work Process Classification System (WPCS) has previously been applied in Alaskan freezer-trawl and freezer-longline fleets to identify causes of injuries and specific hazards, but not to other fishing fleets. Objectives. This descriptive epidemiologic study aimed to explore the application and modification of the WPCS in multiple Alaskan fleets, characterize non-fatal occupational injuries in these fleets, and identify work processes that could be targeted for further investigation and future injury prevention efforts. Design. Traumatic, non-fatal injuries on-board Alaskan commercial fishing vessels were identified through United States Coast Guard investigative reports. Characteristics of injuries, as well as worker characteristics, were analysed. Injuries were coded using the WPCS. Results. We successfully utilized the WPCS to code non-fatal injury cases (n = 136). The most frequent main work processes associated with non-fatal injuries included: on-board trawlers, handling frozen fish and processing the catch; on-board vessels using pot/trap gear, handling the gear and shooting/setting the gear; on-board longliners, traffic on board and hauling the gear; and on-board processor vessels, processing the catch, other work with the catch, and handling frozen fish. Conclusions. The study confirmed that a WPCS can be applied to multiple Alaskan fleets to identify hazardous tasks. Hazards were unique for each vessel gear type. Future injury prevention efforts should target work processes associated with the most frequent and most severe injuries. Future studies should establish time estimates for work processes in order to determine risk estimates. Efforts to improve non-fatal injury reporting, especially on smaller commercial fishing vessels, should be undertaken.To access the supplementary material for this article, please see Supplementary files under ‘Article Tools’ at: http://www.circumpolarhealthjournal.net/index.php/ijch/article/view/30070 This is the publisher’s final pdf.

Community as a source of health in three racial/ethnic communities in Oregon: a qualitative study

BACKGROUND: A 2011 report by the Oregon Health Authority and the Department of Human Services documented disparities in its Latino and American Indian populations on multiple individual-level health indicators. However, research is lacking on the social contexts in which Latinos and American Indians in Oregon live and how these environments influence the health of communities as a whole. To help fill this gap, this study sought to contextualize the social environments that influence the health of Latinos and American Indian residents in three Oregon communities. METHODS: Guided by an ecological framework, we conducted one-time semi-structured qualitative interviews with 26 study participants to identify the prominent health-related issues in the communities and to examine the factors that study participants perceived as enabling or inhibiting healthy lifestyles of community residents. We used a grounded theory approach to perform content and thematic analyses of the data. RESULTS: Study participants identified preventable chronic conditions, such as diabetes, obesity, and hypertension, as the most pressing health concerns in their communities. Results showed that traditional and cultural activities and strong family and community cohesion were viewed as facilitators of good community health. Poverty, safety concerns, insufficient community resources, and discrimination were perceived as barriers to community health. Three themes emerged from the thematic analyses: social connectedness is integral to health; trauma has an ongoing negative impact on health; and invisibility of residents in the community underlies poor health. CONCLUSIONS: This study’s findings provide insight to the social contexts which operate in the lives of some Latinos and American Indians in Oregon. While participants identified community-level factors as important to health, they focused more on the social connections of individuals to each other and the relationships that residents have with their communities at-large. Our findings may also help to explain how the intra- and inter-personal levels, the community/institutional level, and the macro level/public policy contexts can serve to influence health in these communities. For example, trauma and invisibility are not routinely examined in community health assessment and improvement planning activities; nonetheless, these factors appear to be at play affecting the health of residents.Keywords: American Indian, Latino, Migrant and seasonal farmworkers, Trauma, Community healt

Arsenic Exposure and Prevalence of the Varicella Zoster Virus in the United States: NHANES (2003-2004 and 2009-2010)

Background: Arsenic is an immunotoxicant. Clinical reports observe the reactivation of varicella zoster virus (VZV) in people who have recovered from arsenic poisoning and in patients with acute promyelocytic leukemia that have been treated with arsenic trioxide. Objective: We evaluated the association between arsenic and the seroprevalence of VZV IgG antibody in a representative sample of the U.S. population. Methods: We analyzed data from 3,348 participants of the National Health and Nutrition Examination Survey (NHANES) 2003–2004 and 2009–2010 pooled survey cycles. Participants were eligible if they were 6–49 years of age with information on both VZV IgG and urinary arsenic concentrations. We used two measures of total urinary arsenic (TUA): TUA1 was defined as the sum of arsenite, arsenate, monomethylarsonic acid, and dimethylarsinic acid, and TUA2 was defined as total urinary arsenic minus arsenobetaine and arsenocholine. Results: The overall weighted seronegative prevalence of VZV was 2.2% for the pooled NHANES sample. The geometric means of TUA1 and TUA2 were 6.57 μg/L and 5.64 μg/L, respectively. After adjusting for age, sex, race, income, creatinine, and survey cycle, odds ratios for a negative VZV IgG result in association with 1-unit increases in natural log-transformed (ln)-TUA1 and ln-TUA2 were 1.87 (95% CI: 1.03, 3.44) and 1.40 (95% CI: 1.0, 1.97), respectively. Conclusions: In this cross-sectional analysis, urinary arsenic was inversely associated with VZV IgG seroprevalence in the U.S. population. This finding is in accordance with clinical observations of zoster virus reactivation from high doses of arsenic. Additional studies are needed to confirm the association and evaluate causal mechanisms

Is there a link between wealth and cardiovascular disease risk factors among Hispanic/Latinos? : Results from the HCHS/SOL sociocultural ancillary study

OBJECTIVE: To examine the relationship between wealth and cardiovascular disease risk factors among Hispanic/Latinos of diverse backgrounds. DESIGN: This cross-sectional study used data from 4971 Hispanic/Latinos, 18-74 years, who participated in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) baseline exam and the HCHS/SOL Sociocultural Ancillary Study. Three objectively measured cardiovascular disease risk factors (hypertension, hypercholesterolemia, and obesity) were included. Wealth was measured using an adapted version of the Home Affluence Scale, which included questions regarding the ownership of a home, cars, computers, and recent vacations. RESULTS: After adjusting for traditional socioeconomic indicators (income, employment, education), and other covariates, we found that wealth was not associated with hypertension, hypercholesterolemia or obesity. Analyses by sex showed that middle-wealth women were less likely to have hypercholesterolemia or obesity. Analyses by Hispanic/Latino background groups showed that while wealthier Central Americans were less likely to have obesity, wealthier Puerto Ricans were more likely to have obesity. CONCLUSION: This is the first study to explore the relationship between wealth and health among Hispanic/Latinos of diverse backgrounds, finding only partial evidence of this association. Future studies should utilize more robust measures of wealth, and address mechanisms by which wealth may impact health status among Hispanic/Latinos of diverse backgrounds in longitudinal designs
