Pesticide Exposure among Latinx Children in Rural Farmworker and Urban Non-Farmworker Communities: Associations with Locality and Season.

This study uses repeated measures to document the pesticide exposure of rural and urban Latinx children (age eight at baseline), and to compare these children in terms of the frequency and concentration of their exposure to a large set of pesticides, accounting for season. We used silicone wristbands worn for one week up to ten times at quarterly intervals from 2018 to 2022 to assess pesticide exposure in children from rural farmworker (n = 75) and urban non-farmworker (n = 61) families. We determined the detection and concentrations (ng/g) of 72 pesticides and pesticide degradation products in the wristbands using gas chromatography electron capture detection and gas chromatography mass spectrometry. The most frequently detected pesticide classes were organochlorines, pyrethroids, and organophosphates. Controlling for season, organochlorine or phenylpyrazole detections were less likely for rural children than for urban children. Detections of organochlorines, pyrethroids, or organophosphates were lower in spring and summer versus winter. Controlling for season, urban children had greater concentrations of organochlorines, while rural children had greater concentrations of pyrethroids and Chlorpyrifos. Pesticide concentrations were lower in winter and spring compared with summer and fall. These results further document that pesticides are ubiquitous in the living environment for children in vulnerable, immigrant communities.

Community-Engaged Research: Common Themes and Needs Identified by Investigators and Research Teams at an Emerging Academic Learning Health System.

Community-engaged research (CEnR) has emerged within public health and medicine as an approach to research designed to increase health equity, reduce health disparities, and improve community and population health. We sought to understand how CEnR has been conducted and to identify needs to support CEnR within an emerging academic learning health system (aLHS). We conducted individual semi-structured interviews with investigators experienced in CEnR at an emerging aLHS in the southeastern United States. Eighteen investigators (16 faculty and 2 research associates) were identified, provided consent, and completed interviews. Half of participants were women; 61% were full professors of varied academic backgrounds and departments. Interviews were audio-recorded, transcribed, coded, and analyzed using constant comparison, an approach to grounded theory. Twenty themes emerged that were categorized into six domains: Conceptualization and Purpose, Value and Investment, Community-Academic Partnerships, Sustainability, Facilitators, and Challenges. Results also identified eight emerging needs necessary to enhance CEnR within aLHSs. The results provide insights into how CEnR approaches can be harnessed within aLHSs to build and nurture community-academic partnerships, inform research and institutional priorities, and improve community and population health. Findings can be used to guide the incorporation of CEnR within aLHSs.

Building bridges between a community and an academic medical center via community tours.

Academic medical centers (AMCs) face challenges in conducting research among traditionally marginalized communities due to long-standing community mistrust. Evidence suggests that some AMC faculty and staff lack an understanding of the history of distrust and social determinants of health (SDH) affecting their communities. Wake Forest Clinical and Translational Science Institute Program in Community Engagement (PCE) aims to build bridges between communities and Wake Forest Baptist Health by equipping faculty, clinicians, administrators, and staff (FCAS) with a better understanding of SDH. The PCE collaborated with community partners to develop and implement community tours to improve cross-community AMC understanding and communication, enhance knowledge of SDH, and build awareness of community needs, priorities, and assets. Nine day-long tours have been conducted with 92 FCAS. Tours included routes through under-resourced neighborhoods and visits to community assets. Participant evaluations assessed program quality; 89% reported enhanced understanding of access-to-care barriers and how SDH affect health; 86% acknowledged the experience would improve future interactions with participants and patients; and 96% agreed they would recommend the tour to colleagues. This work supports the use of community tours as a strategy to improve cross-community AMC communication, build trust, and raise awareness of community needs, priorities, and assets.

Influencing Public Transportation Policy Through Community Engagement and Coalition Building: Process and Preliminary Outcomes.

THE PROBLEM: Public transportation is a social determinant of health and is crucial to aspects of health like access to healthcare, employment, and nutrition. Existing health inequities are exacerbated by inefficient or inaccessible public transportation systems. PURPOSE: To provide a detailed analysis of the issues and concerns related to public transportation in Winston-Salem, North Carolina, and describe how coalition-building was used to influence positive change in transportation policy. KEY POINTS: Members from various organizations aligned with local transit riders to create the Transportation Coalition and advocate for extended night and weekend services for the Winston-Salem public transportation system. CONCLUSIONS: Partnerships between community-based organizations are crucial to identifying and addressing the needs of a community. The Transportation Coalition will continue its work in local public transportation policy. A long-term policy objective is fare-free transit on the city bus system.

In vivo two-photon imaging of neuronal and brain vascular responses in mice chronically exposed to ethanol.

The effects of ethanol on brain function have been extensively studied using a variety of in vitro and in vivo techniques. For example, electrophysiological studies using brain slices from rodents and non-human primates have demonstrated that acute and chronic exposure to ethanol alters the intrinsic excitability and synaptic signaling of neurons within cortical and sub-cortical areas of the brain. In humans, neuroimaging studies reveal alterations in measures of brain activation and connectivity in subjects with alcohol use disorder. While complementary, these methods are inherently limited due to issues related to either disruption of normal sensory input (in vitro slice studies) or resolution (whole brain imaging). In the present study, we used 2-photon laser scanning microscopy in intact animals to assess the impact of chronic ethanol exposure on sensory-evoked neuronal and vascular responses. Adult male C57BL/6J mice were exposed to four weekly cycles of chronic intermittent ethanol (CIE) exposure, while control mice were exposed to air. After withdrawal (≥72 h), a cranial window was placed over the primary visual cortex (V1), and sensory-evoked responses were monitored using the calcium indicator OGB-1. CIE exposure produced small but significant changes in response amplitude (decrease) and orientation selectivity of V1 neurons (increase). While arteriole diameter did not differ between control and CIE mice under baseline conditions, sensory-evoked dilation was enhanced in vessels from CIE-exposed mice as compared to controls. This was accompanied by a reduced latency in response to stimulation. In separate experiments, pial arteriole diameter was measured in the barrel cortex of control and CIE-exposed mice. Baseline diameter of barrel cortex arterioles was similar between control and CIE-exposed mice, but unlike vessels in V1, sensory-evoked dilation of barrel cortex arterioles was similar between the two groups. Together, the results of these studies suggest that chronic exposure to alcohol induces changes in neurovascular coupling that are region-dependent.

Self-care habits among people who inject drugs with skin and soft tissue infections: a qualitative analysis.

BACKGROUND: Injection drug use is on the rise in the USA, and skin and soft tissue infections (SSTI) are a common complication, resulting in significant morbidity and mortality. Due to structural barriers to care-seeking, many people who inject drugs avoid formal care and resort to self-care techniques, but little is known about the nature of these techniques, or more generally about the accuracy or breadth of this population's knowledge of SSTIs. METHODS: Semi-structured qualitative interviews were conducted with 12 people who inject heroin in two metropolitan areas: Sacramento and Boston, USA. RESULTS: These interviews reveal a robust and accurate knowledge base regarding skin infections, including the progression from simple cellulitis to an abscess, and acknowledgment of the possibility of serious infections. Nonetheless, there remains a reticence to seek care secondary to past traumatic experiences. A step-wise approach to self-care of SSTI infections was identified, which included themes of whole-body health, topical applications, use of non-prescribed antibiotics, and incision and drainage by non-medical providers. CONCLUSIONS: The reported SSTI self-care strategies demonstrate resilience and ingenuity, but also raise serious concerns about inappropriate antibiotic consumption and complications of invasive surgical procedures performed without proper training, technique, or materials. Harm reduction agencies and health care providers should work to obviate the need for these potentially dangerous practices by improving healthcare access for this population. In the absence of robust solutions to meet the needs of this population, education materials should be developed to optimize the efficacy and minimize the harms of these practices, while empowering and supporting the autonomy of people who use drugs and providing clear guidance on when self-care should be abandoned in favor of formal medical care.

A Citizen Science Approach to Determine Physical Activity Patterns and Demographics of Greenway Users in Winston-Salem, North Carolina.

Citizen science is a growing method of scientific discovery and community engagement. To date, there is a paucity of data using citizen scientists to monitor community level physical activity, such as bicycling or walking; these data are critical to inform community level intervention. Volunteers were recruited from the local community to make observations at five local greenways. The volunteers picked their location, time to collect data and duration of data collection. Volunteer observations included recording estimated age, race or ethnicity and activity level of each individual they encountered walking, running or bicycling on the greenway. A total of 102 volunteers were recruited to participate in the study, of which 60% completed one or more observations. Average observational time lasted 81 minutes and resulted in recording the demographics and physical activity of a mean of 48 people per session. The majority of adult bicyclists observed were biking at a moderate pace (86%) and were white (72%) males (62%). Similar results were observed for those walking. We demonstrate the feasibility of using citizen scientists to address the current scarcity of data describing community-level physical activity behavior patterns. Future work should focus on refining the citizen science approach for the collection of physical activity data to inform community-specific interventions in order to increase greenway use.

Cannabis use and acute coronary syndrome.

Introduction: Cannabis smoking can result in elevation of heart rate and blood pressure immediately after use, possibly from sympathetic nervous system stimulation and parasympathetic nervous system inhibition. Vascular inflammation, platelet activation, and carboxyhemoglobin generation have also been proposed as potential side effects of cannabis smoking. As such, an association between cannabis use and acute coronary syndrome has been postulated. Objective: The objective of our study was to analyze systematically the medical literature pertaining to this putative association. Methods: PubMed, Google Scholar, and OpenGrey were queried using a unique search string. All human trials, case series, or case reports of cannabis use and acute coronary syndrome in any language were considered in the literature search. The definition of acute coronary syndrome represented a penumbra that included chest pain, angina pectoris, unstable angina, myocardial infarction, myocardial ischemia, and cardiac arrest. Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were followed. Our final search strategy included free-text words (TW): ("cannabis"[TW] OR "marijuana"[TW]) AND ("acute coronary syndrome"[TW] OR "myocardial" OR "ischemia"[TW] OR "infarction"[TW] OR "chest pain"[TW] OR "cardiac arrest"[TW] OR "angina"[TW]). To remain consistent over a span of five decades, we specifically did not include any publications with non-phytogenic, non-smoked cannabis as the sole etiology, as these are relatively recent and may possess additional pharmacologic characteristics compared to phytogenic cannabinoids. Therefore, for the purpose of this review, the term "cannabis" refers to the smoked phytogenic form. The search resulted in 325 articles. References in each selected publication were carefully hand-searched for any additional reports having relevance, and a total of 12 publications were identified in this manner. Following comparison and discussion amongst the co-authors, duplicate and non-relevant publications were removed, and a total of 85 publications involving 541,518 human subjects were selected for inclusion. Results were synthesized and reviewed by the authors for relevance. Clinical trials, observational studies, retrospective studies, case series, and case reports were graded using Oxford Centre for Evidence-based Medicine guidelines. Results: There were no Level I randomized blinded controlled studies specifically addressing the cannabis/acute coronary syndrome association. However, there were five Level I systematic reviews, 14 Level II studies with 83,961 subjects, and 14 Level III studies with 457,495 subjects. Conclusions from 28 of these 33 studies highlighted an increased risk of both acute coronary syndrome and chronic cardiovascular disease from cannabis use. The systematic reviews were wide-ranging in topic and scale, and none specifically focused on the association between cannabis use and acute coronary syndrome. The dissenting studies included two systematic reviews, one concluding there was limited and weak evidence for association of cardiovascular disease and acute coronary syndromes with cannabis use, and another citing the evidence was inconclusive. The other dissenting articles were two longitudinal prospective studies and a retrospective review concluding cannabis users had lower post-myocardial infarction mortality. There were 51 case series (Level IV) and case reports (Level V) with 62 subjects. Six cases were female (10%). Average age was 31 ± 12 years, reported maximum heart rate was 88 ± 21 bpm, systolic blood pressure was 125 ± 32 mmHg, and diastolic blood pressure was 80 ± 17 mmHg. ST-segment elevation was documented on 37 (60%) electrocardiograms, and the most common angiographic finding was left anterior descending coronary arterial occlusion and/or stenosis in 22 (35%) patients. Concomitant cardiomyopathy was described in 21 (34%) cases. There were 14 (23%) deaths attributed to acute coronary syndrome associated with cannabis use. Conclusion: There were five Level I systematic reviews, 14 Level II studies with 83,961 subjects, and 14 Level III studies with 457,495 subjects. All but five Level I-III publications highlighted an increased risk of both acute coronary syndrome and chronic cardiovascular disease associated with cannabis use.

Violence as a health disparity: Adolescents' perceptions of violence depicted through photovoice.

Violence is a public health issue that disproportionately affects adolescents from historically marginalized communities. In response to growing concerns of local violence, our community-academic partnership explored adolescents' perspectives about violence, including perceptions of its causes, consequences, and potential solutions. Ten adolescents participated in a 12-week photovoice project. They received training in basic research methodologies, documented representations of violence through digital photography and creative writing, engaged in empowerment-based photo-discussions, and presented their work to influential advocates in a community forum. Adolescents and staff conducted a thematic analysis of photographs and narratives from which 10 themes emerged across 3 domains: a culture of violence and oppression, structural violence, and mental and physical health. Adolescents presented their work to community stakeholders in a public forum to foster additional discussions regarding violence in the community. This photovoice project yielded rich qualitative insight into adolescents' experiences with and perceptions of violence.

Negative experiences of pain and withdrawal create barriers to abscess care for people who inject heroin. A mixed methods analysis.

BACKGROUND: Skin and soft tissue infections (SSTIs) are prevalent among people who inject heroin (PWIH). Delays in seeking health care lead to increased costs and potential mortality, yet the barriers to accessing care among PWIHs are poorly understood. METHODS: We administered a quantitative survey (N = 145) and conducted qualitative interviews (N = 12) with PWIH seeking syringe exchange services in two U.S. cities. RESULTS: 66% of participants had experienced at least one SSTI. 38% reported waiting two weeks or more to seek care, and 57% reported leaving the hospital against medical advice. 54% reported undergoing a drainage procedure performed by a non-medical professional, and 32% reported taking antibiotics that were not prescribed to them. Two of the most common reasons for these behaviors were fear of withdrawal symptoms and inadequate pain control, and these reasons emerged as prominent themes in the qualitative findings. These issues are often predicated on previous negative experiences and exacerbated by stigma and an asymmetrical power dynamic with providers, resulting in perceived barriers to seeking and completing care for SSTIs. CONCLUSIONS: For PWIH, unaddressed pain and withdrawal symptoms contribute to profoundly negative health care experiences, which then generate motivation for delaying care SSTI seeking and for discharge against medical advice. Health care providers and hospitals should develop policies to improve pain control, manage opioid withdrawal, minimize prejudice and stigma, and optimize communication with PWIH. These barriers should also be addressed by providing medical care in accessible and acceptable venues, such as safe injection facilities, street outreach, and other harm reduction venues.

Child Work Safety on the Farms of Local Agricultural Market Producers: Parent and Child Perspectives.

Agriculture is a hazardous industry, yet there are few regulations on the ages at which children may engage in farm work. Local agricultural market producers (LAMPs) are a growing subset of farmers within "sustainable agriculture" who engage in direct-to-consumer and direct-to-retailer enterprises. This study explores the occupational health and safety perceptions of parents and children for children who work on their families' LAMP farms. In-depth interviews were conducted with 12 parent-child dyads from LAMP farms in Illinois and North Carolina. Four themes emerged from these 24 interviews; parents and children perceived that: (1) the nature of small farms makes them safer than industrial agricultural operations; (2) child safety on farms is common sense; (3) avoiding hazardous tasks keeps children safe; and (4) parents know best (compared to regulations) about ways to keep their children safe. Some of these themes echo the results of earlier studies conducted with more conventional farms. Further research is needed to develop programs to improve child occupational safety on LAMP farms.

Using "Policy Briefs" to Present Scientific Results of CBPR: Farmworkers in North Carolina.

BACKGROUND: Using scientific results to inform policy that improves health and well-being of vulnerable community members is essential to community-based participatory research (CBPR). OBJECTIVES: We describe "policy briefs," a mechanism developed to apply the results of CBPR projects with migrant and seasonal farmworkers to policy changes. LESSONS LEARNED: Policy briefs are two-page summaries of published research that address a single policy issue using language and graphics to make the science accessible to diverse audiences. Policy brief topics are selected by community advocates, based on collaborative research, and address a specific policy or regulation. Development is an iterative process of discussion with community representatives. Briefs have been used to provide information to advocates, state and national policymakers, and the public. CONCLUSIONS: Disseminating CBPR results to address policy is needed. Collaborating with community partners to produce policy briefs ensures that information about concerns and struggles reflects their priorities.

The impacts of pesticide and nicotine exposures on functional brain networks in Latino immigrant workers.

Latino immigrants that work on farms experience chronic exposures to potential neurotoxicants, such as pesticides, as part of their work. For tobacco farmworkers there is the additional risk of exposure to moderate to high doses of nicotine. Pesticide and nicotine exposures have been associated with neurological changes in the brain. Long-term exposure to cholinesterase-inhibiting pesticides, such as organophosphates and carbamates, and nicotine place this vulnerable population at risk for developing neurological dysfunction. In this study we examined whole-brain connectivity patterns and brain network properties of Latino immigrant workers. Comparisons were made between farmworkers and non-farmworkers using resting-state functional magnetic resonance imaging data and a mixed-effects modeling framework. We also evaluated how measures of pesticide and nicotine exposures contributed to the findings. Our results indicate that despite having the same functional connectivity density and strength, brain networks in farmworkers had more clustered and modular structures when compared to non-farmworkers. Our findings suggest increased functional specificity and decreased functional integration in farmworkers when compared to non-farmworkers. Cholinesterase activity was associated with population differences in community structure and the strength of brain network functional connections. Urinary cotinine, a marker of nicotine exposure, was associated with the differences in network community structure. Brain network differences between farmworkers and non-farmworkers, as well as pesticide and nicotine exposure effects on brain functional connections in this study, may illuminate underlying mechanisms that cause neurological implications in later life.

Injection-site vein loss and soft tissue abscesses associated with black tar heroin injection: A cross-sectional study of two distinct populations in USA.

BACKGROUND: Injection-site vein loss and skin abscesses impose significant morbidity on people who inject drugs (PWID). The two common forms of street heroin available in the USA include black tar and powder heroin. Little research has investigated these different forms of heroin and their potential implications for health outcomes. METHODS: A multiple-choice survey was administered to a sample of 145 participants seeking services at reduction facilities in both Sacramento, CA and greater Boston, MA, USA. Multivariate regression models for reporting one or more abscesses in one year, injection-site veins lost in six months, and soft tissue injection. RESULTS: Participants in Sacramento exclusively used black tar (99%), while those in Boston used powder heroin (96%). Those who used black tar heroin lost more injection-site veins (ß=2.34, 95% CI: 0.66-4.03) and were more likely to report abscesses (AOR=7.68, 95% CI: 3.01-19.60). Soft tissue injection was also associated with abscesses (AOR=4.68, 95% CI: 1.84-11.93). Consistent venous access (AOR: 0.088, 95% CI: 0.011-0.74) and losing more injection sites (AOR: 1.22, 95% CI: 1.03-1.45) were associated with soft tissue injection. CONCLUSION: Use of black tar heroin is associated with more frequent abscesses and more extensive vein loss. Poor venous access predisposes people who inject drugs to soft tissue injection, which may constitute a causal pathway between black tar heroin injection and abscess formation. The mechanisms by which black tar heroin contributes to vein loss and abscess formation must be further elucidated in order to develop actionable interventions for maintaining vein health and decreasing the abscess burden. Potential interventions include increased access to clean injection equipment and education, supervised injection facilities, opioid substitution therapy, and supply chain interventions targeting cutting agents.

Organophosphate Pesticide Urinary Metabolites Among Latino Immigrants: North Carolina Farmworkers and Non-farmworkers Compared.

BACKGROUND: This analysis documents detections and concentrations of the six dialkylphosphate (DAP) urinary metabolite of organophosphorus (OP) pesticides among North Carolina Latino migrant farmworkers, with comparison to non-farmworker Latino immigrants. METHODS: Participants provided up to four urine samples during the 2012 and 2013 agricultural seasons. Composite urine samples for each year were analyzed. RESULTS: DAP urinary metabolite detections were similar in farmworkers and non-farmworker; for example, for 2012, 75.4% of farmworkers and 67.4% of non-farmworkers and, for 2013, 89.3% of farmworkers and 89.7% of non-farmworkers had dimethylthiophosphate detections. DAP geometric mean concentrations were high; for example, dimethylphosphate concentrations among farmworkers were 11.39 µg/g creatinine for 2012 and 4.49 µg/g creatinine for 2013, while they were 10.49 µg/g creatinine for 2012 and 1.97 µg/g creatinine for 2013 for non-farmworkers CONCLUSIONS:: Research to reduce pesticide exposure among Latino farmworkers and non-farmworkers is needed.

Changes in DNA methylation over the growing season differ between North Carolina farmworkers and non-farmworkers.

PURPOSE: The occupational risk to farmworkers, particularly chronic exposure to pesticides, is an acknowledged environmental and work-related health problem. Epigenetics has recently been shown to contribute to a number of complex diseases and traits, including measures of cognitive function and preclinical neurodegenerative disease. We sought to determine whether changes in DNA methylation existed between farmworker and non-farmworker populations and to identify the genes most likely involved in those changes. METHODS: Eighty-three farmworkers and 60 non-farmworkers were selected from PACE4, a community-based, participatory research project comparing occupational exposures between immigrant Latino farmworker and non-farmworker manual workers. Measurements of DNA methylation were performed with the Infinium HumanMethylation450 BeadChip, at the beginning and end of the 2012 growing season. Bonferroni adjustment was used to identify significant findings (p = 1.03 × 10(-7), based on 485,000 tested methylation sites), although less stringent criteria (i.e., p ≤ 1 × 10(-6)) were used to identify sites of interest. Expression quantitative trait locus (eQTL) databases were used to help identify the most likely functional genes for each associated methylation site. RESULTS: Methylation at 36 CpG sites, located in or near 72 genes, differed between the two groups (p ≤ 1 × 10(-6)). The difference between the two groups was generally due to an increase in methylation in the farmworkers and a slight decrease in methylation in the non-farmworkers. Enrichment was observed in several biological pathways, including those involved in the immune response, as well as growth hormone signaling, role of BRCA1 in DNA damage response, p70S6K signaling, and PI3K signaling in B lymphocytes. CONCLUSIONS: We identified considerable changes in DNA methylation at 36 CpG sites over the growing season that differed between farmworkers and non-farmworkers. Dominant pathways included immune-related (HLA) processes, as well as a number of diverse biological systems. Further studies are necessary to determine which exposures or behaviors are responsible for the observed changes, and whether these changes eventually lead to disease-related phenotypes in this population.

Brain Anatomy in Latino Farmworkers Exposed to Pesticides and Nicotine.

OBJECTIVE: Migrant tobacco farmworkers experience regular occupational exposure to pesticides and nicotine. The present study was designed to determine whether there are differences in brain anatomy between Latino farmworkers and non-farmworkers. METHODS: Magnetic resonance brain images were compared between farmworkers and non-farmworkers. In addition, blood cholinesterase activity and urinary cotinine levels were also used to identify associations with pesticide and nicotine exposure. RESULTS: Farmworkers had greater gray matter signal in putamen and cerebellum, and lower gray matter signal in frontal and temporal lobes. Urinary cotinine was associated with the observed differences in brain anatomy, but blood cholinesterase activity was not. CONCLUSIONS: Nicotine exposure was associated with neuroanatomical differences between Latino farmworkers and non-farmworkers. Future studies are needed to differentiate iron deposition from brain atrophy and to further assess the potential role of nicotine and pesticide exposure.

Olfactory Function in Latino Farmworkers: Subclinical Neurological Effects of Pesticide Exposure in a Vulnerable Population.

OBJECTIVES: We compared olfactory function in pesticide-exposed Latino farmworkers and nonfarmworkers to explore its use as a subclinical indicator of neurological pesticide effects. METHODS: We recruited 304 current farmworkers and 247 nonfarmworkers. All completed odor identification (14 odors) and threshold tests (16 concentrations of n-butanol) using a well-established methodology. RESULTS: Farmworkers reported significantly greater lifetime pesticide exposure. Performance on both olfactory tests declined with age. Odor identification performance did not differ between groups. For odor threshold, farmworkers needed significantly higher concentrations to detect the odor. Results were unchanged when adjusted for sex, age, and smoking. CONCLUSION: Olfactory function differences between farmworkers and nonfarmworkers suggest possible neurological effects. Because declining olfactory function is an early symptom of Parkinson disease and related conditions, it is a possible subclinical indicator of neurodegenerative disease in this vulnerable worker population.

Alcohol Consumption and Risk for Dependence Among Male Latino Migrant Farmworkers Compared to Latino Nonfarmworkers in North Carolina.

BACKGROUND: Our aim was to describe alcohol consumption behavior of male Latino migrant farmworkers, compare their alcohol consumption behavior with that of other male Latino immigrants, and determine factors associated with risk for alcohol dependence among Latino immigrant workers. METHODS: Cross-sectional data were drawn from baseline interviews conducted as part of a larger community-based participatory research project examining the cognitive and neurological outcomes of pesticide exposure. A total of 235 farmworkers and 212 nonfarmworkers completed interviews between May and August 2012. RESULTS: Although 17.5% of the North Carolina Latino farmworkers report never having drunk alcohol, and a total of 34.5% report not having drunk alcohol in the previous 3 months, 48.5% engaged in heavy episodic drinking (HED) in the previous 3 months, and 23.8% frequently engaged in HED during this period. Farmworkers and nonfarmworkers did not differ significantly in alcohol consumption behavior. Farmworkers and nonfarmworkers did differ significantly in each component of the CAGE scale, with 37.9% of farmworkers and 16.0% of nonfarmworkers being at risk for alcohol dependence (p < 0.0001). Significant factors for being at risk for alcohol dependence were stress (odds ratio 1.06, 95% confidence interval 1.03, 1.09) and being a farmworker (odds ratio 3.58, 95% confidence interval 2.12, 6.06). Being married reduced the risk of alcohol dependence (odds ratio 0.45, 95% confidence interval 0.23, 0.87). CONCLUSIONS: Latino farmworkers and nonfarmworkers consume relatively large amounts of alcohol and engage in HED at relatively high rates. Latino farmworkers have very high rates of risk for alcohol dependence. Policy changes and public health interventions are needed to address these concerns for a population that is vital to the agricultural economy.

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.
