Maternal blood pressure and birth weight associations in U.S.-born and foreign-born Latinas.

OBJECTIVES: Research suggests that acculturating to the United States is detrimental for immigrants' health. Consistent with this pattern, higher levels of U.S. acculturation among Latina-American women have been associated with giving birth to lower birth weight babies. The mechanisms that shape this shift in pregnancy health are not clear, but researchers have begun to consider the role of physiological systems that are sensitive to social experience. The present study examined the association of cultural orientation with blood pressure (BP) trajectories over the course of pregnancy. METHOD: In a study of 1,011 U.S.- and foreign-born Latina-American women, cultural orientation was assessed and multiple BP measures were collected throughout pregnancy. Postpregnancy data, including gestational age-adjusted birth weight, were extracted from medical records. Bayesian structural equation models examined average BP and slopes of BP change during pregnancy while accounting for psychosocial stress, support, and pregnancy health-related factors (e.g., maternal age, smoking). RESULTS: We found evidence that greater U.S. orientation was associated with higher diastolic blood pressure (DBP) and steeper increases in DBP, which was associated with less fetal growth. CONCLUSIONS: This is the first evidence that BP may mediate the association between cultural orientation and pregnancy outcomes in Latina-American women. These findings advance our understanding of the biopsychosocial pathways through which acculturation to the U.S. links with health. As scholars seek to better understand the influence of U.S. acculturation on health, focusing on the cardiovascular system and other physiological systems that are sensitive to social experience is warranted and likely to prove valuable.

California cannabis cultivation and processing workers: A qualitative analysis of physiological exposures and health effects.

INTRODUCTION: Cannabis is a multi-billion-dollar California industry, but little is known about the occupational hazards or health experiences of cannabis cultivation workers. Respiratory and dermal exposures, musculoskeletal hazards, and other agricultural hazards have been identified in previous research. Even in a post-legalization framework, cannabis work is stigmatized and most cannabis is still produced illegally. Qualitative research is essential for establishing rapport with cannabis workers to understand their experiences and concerns. METHODS: We conducted semi-structured discussions with four focus groups including 32 cannabis workers total, and 9 key informants who were workers, industry experts, and business owners or managers. Transcribed results were analyzed to identify key themes on physiological exposures and health effects. RESULTS: The majority (81.3%) of focus group participants were seasonal migrant cannabis trimmers. Themes emerged of respiratory and dermal exposures and outcomes, musculoskeletal disorders, and physical hazards including living conditions. Workers reported respiratory symptoms and rashes from exposure to cannabis, mold, and pesticides. Musculoskeletal pain was ubiquitous due to inadequate seating and long shifts performing repetitive tasks. Seasonal workers experienced chronic exposure to cold conditions and unsanitary housing. Management-level interviewees and other industry stakeholders described concerns and experiences that differed from those of workers. DISCUSSION: The results were consistent with existing research on cannabis worker health, with workers reporting respiratory and dermal exposure and symptoms, musculoskeletal hazards, and physical hazards associated with agricultural work. In addition, we found that workers were affected by substandard living conditions, remote and isolated work environments, and an absence of training.

Effectiveness of a worksite lifestyle intervention to reduce BMI among farmworkers in California: a cluster randomised controlled trial.

OBJECTIVE: To evaluate the effectiveness of PASOS SALUDABLES, a culturally tailored lifestyle intervention to prevent obesity and diabetes among Latino farmworkers, when implemented at large scale in the worksite. DESIGN: This study was a two-arm parallel group, cluster randomised controlled trial, where participants received either a twelve-session lifestyle intervention (intervention) or six-session leadership training (control) at their worksite. The intervention was delivered by Promotoras in Spanish. All sessions were conducted at the worksites (ranches) during meal breaks. Blinded, trained research assistants collected socio-demographic and outcome data (i.e. BMI as primary outcome and waist circumference, glycated Hb (HbA1c), cholesterol and blood pressure as secondary outcomes) at baseline and follow-up assessments (i.e. 3 months, 6 months, 1 year and 1·5 years). SETTING: Recruitment and intervention delivery occurred at twelve study ranches in Oxnard, California. PARTICIPANTS: We enrolled farmworkers hired by a large berry grower company, who were ≥18 years old, spoke Spanish and were free of diabetes at screening. RESULTS: A total of 344 workers were enrolled in the intervention and 271 in the control group. The intervention resulted in attenuated increase of BMI over time; however, the difference in trend between groups was not significant (ß = -0·01 for slope difference, P = 0·29). No significantly different trend by group was observed in secondary outcomes (P > 0·27). CONCLUSIONS: The worksite intervention, implemented during meal breaks, did not reduce BMI or other clinical indicators. Nevertheless, this study supports the feasibility of recruiting and engaging the Latino farmworker population in workplace health promotion interventions.

Migrant workers, essential work, and COVID-19.

Globally, migrant and immigrant workers have borne the brunt of the COVID-19 pandemic as essential workers. They might be a Bulgarian worker at a meat processing plant in Germany, a Central American farmworker in the fields of California, or a Filipino worker at an aged-care facility in Australia. What they have in common is they are all essential workers who have worked throughout the coronavirus pandemic and have been infected with coronavirus at work. COVID-19 has highlighted the inequitable working conditions of these workers. In many instances, they are employed precariously, and so are ineligible for sick leave or social security, or COVID-19 special payments. If these are essential workers, they should get at least the same health and safety benefits of all nonessential workers. Improving the working and living conditions of migrant workers can and should be a positive outcome of the coronavirus pandemic.

The Manila Declaration on Migration and Health: commentary of the Association of Pacific Rim Universities Global Health Program.

BACKGROUND: Migration has played, and continues to play, an important role in shaping our global economy. As of 2017, there were 258 million international migrants worldwide, over 100 million of whom came from the Asia-Pacific region. Migration is increasingly recognized as a social determinant of health, as migrants often experience vulnerabilities that make them susceptible to a range of negative health outcomes. Addressing the health and human rights concerns of migrants requires concerted and global efforts from many stakeholders, including universities. METHODS: The Global Health Program of the Association of Pacific Rim Universities (APRU), a non-profit network of more than 50 universities in the region, is an example of an avenue to foster research, innovation, collaborative engagement, and large-scale advocacy around migration and health. In 2017, a special half-day workshop was held in Manila, convening 167 participants from 10 economies and 21 disciplines. The goal of the workshop was to delineate the role of universities in promoting migrant health and well-being. The global health experts from a diverse set of backgrounds collaboratively developed a policy statement to be used to better address migrant health and human rights. The objective of this paper is to disseminate the policy statement, highlighted specific action items that universities can take to protect and promote migrant health. RESULTS: The Manila Declaration on Migration and Health highlights that universities must ensure that their campuses are safe, supportive, and empowering environments for all migrants and their families. Universities are also urged to capitalize on their educational and research expertise to generate data on migrant experiences and communicate this research to policymakers. CONCLUSIONS: This commentary highlights how institutions of higher education can serve as powerful avenues for promoting migrant health and human rights. Universities can play a vital role in building awareness and sensitivity to migrant challenges and needs, as well as helping to develop policy frameworks appropriate to their diverse contexts to guide, promote, and reinforce commitment to migrant rights and health. Universities should also ensure that their campuses are safe, supportive, and empowering environments for all migrants and their families.

Acute kidney injury and workload in a sample of California agricultural workers.

BACKGROUND: Kidney damage is associated with an increased workload in high ambient temperatures and may represent a pathway to chronic kidney disease of unknown origin in agricultural workers. We tested the associations of workload and heat with acute kidney dysfunction in California agricultural workers. METHODS: We recruited a convenience sample of 471 agricultural workers from 29 farms in California during two summer harvest seasons. The sustained 3-minute maximum workload was estimated using accelerometer data collected from Actical monitors and individual heat load through elevations in core body temperature. Acute kidney injury (AKI) was defined by a change in serum creatinine of ≥0.3 mg/dL or ≥1.5 times the preshift creatinine over the course of the work shift. Associations between AKI and workload were modeled using logistic regression, controlling for demographic, physiologic, and occupational variables. RESULTS: Of the total, 357 workers (75.8%) had accelerometer readings in the moderate workload category, 93 (19.7%) had readings in the vigorous category. 177 (36%) had elevations of core body temperature ≥1°C; 72 workers (14.9%) demonstrated evidence of AKI after a single day of agricultural work. The workload category was associated with an increased adjusted odds of AKI (1.92; 95% confidence interval, 1.05-3.51). Piece-rate work was also associated with increased adjusted odds of AKI (3.02; 95% CI, 1.44-6.34). CONCLUSIONS: Heavy occupational workload and piece-rate work were associated with acute effects on the renal health of agricultural workers. This indicates that occupations requiring high physical effort put workers at risk for AKI, possibly independent of ambient and core body temperature. Changes to agricultural practices may reduce the risk of renal disorders for these workers.

Hydration Choices, Sugary Beverages, and Kidney Injury in Agricultural Workers in California.

PURPOSE: Agricultural workers working in high ambient temperatures are at risk for acute kidney injury. Despite recommendations to maintain hydration, workers likely do not drink enough to protect their renal function. Additionally, new research suggests that rehydration with sugary beverages adds additional risk to kidneys already stressed by high heat and workload. We assessed hydration choices during a work shift and tested associations of rehydration using sugary beverages with acute kidney injury. METHODS: We recruited a convenience sample of workers on farms over two summers. We estimated acute kidney injury via pre- and post-shift serum creatinine readings from capillary blood samples. We used self-reported measures of the volume and type of fluids workers consumed during their shifts. We also measured changes in core body temperature, ambient temperature, and workload. We used logistic regression to estimate associations of sugary drinks with acute kidney injury, while controlling for physiologic and occupational variables. FINDINGS: In our sample of 445 participants, we found that men drink more than women do overall, including more than a liter of water than women (2.9 L compared to 1.9 L, respectively). The total volume workers drank was associated with increased odds of acute kidney injury (adjusted odds ratio 1.47, 95% confidence interval 1.09-1.99). We found no association of sugary drinks with acute kidney injury. CONCLUSIONS: These findings provide important information about what men and women use to hydrate during the work day and suggest that they do not drink enough to maintain adequate hydration. Increased fluid intake during the work day may be a result of vigorous workload, which could explain the increased risk for acute kidney injury. Nurses play an important role in educating agricultural workers about the importance of maintaining hydration at work. CLINICAL RELEVANCE: This study advances current knowledge of occupational risk factors for acute kidney injury in agricultural workers. Nurses may be the only point of care for this vulnerable population and are therefore in a unique position to educate on the importance of proper hydration during work.

Impacts of weather, work rate, hydration, and clothing in heat-related illness in California farmworkers.

BACKGROUND: The primary aim of this study was to investigate the effects of work rate, hydration status, and clothing on core body temperature (CBT) on California farmworkers. METHODS: Two hundred and eighty-seven farmworkers were recruited in Summer 2015, with 259 participants having sufficient data for analysis. We collected CBT, ambient temperature, work rate, body weight loss, and clothing worn by each participant throughout the work day and demographic data from a questionnaire. RESULTS: Multiple regression with CBT as the outcome was used to determine the adjusted associations between CBT, environmental heat load, and worker characteristics. The multivariate regression model showed statistically significant associations of CBT with work rate (ß = .006, 95% CI [0.004, 0.009]) and wet-bulb globe temperature (ß = .03, 95% CI [0.017, 0.05]). CONCLUSION: Results suggest that among our population workload is the primary modifiable risk factor for heat-related illness. As expected, the ambient temperature was also associated with higher risk.

Migrant Workers and Their Occupational Health and Safety.

In 2015, approximately 244 million people were transnational migrants, approximately half of whom were workers, often engaged in jobs that are hazardous to their health. They work for less pay, for longer hours, and in worse conditions than do nonmigrants and are often subject to human rights violations, abuse, human trafficking, and violence. Worldwide, immigrant workers have higher rates of adverse occupational exposures and working conditions, which lead to poor health outcomes, workplace injuries, and occupational fatalities. Health disparities of immigrant workers are related to environmental and occupational exposures and are a result of language/cultural barriers, access to health care, documentation status, and the political climate of the host country. Recommendations on global and local scales are offered as potential solutions to improving the health of immigrant workers.

Collaborative research and actions on both sides of the US-Mexico border to counteract type 2 diabetes in people of Mexican origin.

BACKGROUND: Type 2 Diabetes (T2D) is now a massive epidemic in both California and Mexico, with serious consequences for social and economic well-being. A large proportion of these populations share common ethnic backgrounds. Yet diverse environmental and social conditions across regions create unique opportunities to explore the ways that T2D risk, incidence, management and outcomes manifest. MAIN TEXT: An action-oriented research consortium headed up by the University of California and Universidad Nacional Autónoma de Mexico was constituted to set priorities for bi-national translational research, in an attempt to implement and evaluate clinical, public health and policy actions to decrease the burden of T2D for people of Mexican origin. In this paper, we describe the epidemiology of T2D in Mexico and California, review current efforts to combat the epidemic, highlight gaps in knowledge and identify urgent areas of opportunity for collaboration. The group has developed a common research agenda and funding has been obtained to evaluate biological samples from the 2016 Mexican Health Survey, collaborate in a telemedicine-based retinopathy project, implement interventions in food banks, promote a communications campaign, and design a large-scale diabetes prevention effectiveness trial. CONCLUSIONS: T2D has caused a state of emergency in Mexico and is a major health problem among Mexican populations on both sides of the border. Understanding the commonalities and differences between California and Mexico for those of Mexican origin with respect to T2D, when combined with a sharing of knowledge and advances, can produce a bi-national translational research agenda to inform relevant policy and practice. Amidst economic and political uncertainty and limited healthcare budgets, this collaboration can contribute to the development of scientific evidence to inform policies and interventions. This may provide a promising collaborative model that could be expanded to other health conditions and regions of the world.

Protocol for a cluster randomized controlled trial to study the effectiveness of an obesity and diabetes intervention (PASOS) in an immigrant farmworker population.

BACKGROUND: Studies have shown that the prevalence of overweight, obesity and diabetes are higher in the largely Hispanic, immigrant farmworker population in California. Though to date, few interventional studies have focused on these issues in this at-risk population. The objective of this paper is to describe the study design of a cluster randomized controlled trial aimed at evaluating the effectiveness of an obesity and diabetes work place intervention in an immigrant farm worker population. METHODS: PASOS is an obesity and diabetes intervention program that will be implemented on ranches where immigrant farmworkers spend a considerable amount of time each day. This cluster randomized controlled study will enroll approximately 600 farmworkers. Using a uniform distribution for random number generation, ranches are randomized using a 1:1 ratio as either control or intervention. Baseline data will be taken from eligible participants and analyzed against data collected at the post-intervention, 6-month, 1-year, and 1.5-year follow-ups. The enrollment period is 1.5 years. DISCUSSION: Few studies have been conducted that aim to evaluate the effectiveness of a worksite intervention for obesity and diabetes prevention in a largely Hispanic, farmworker population. This study has been tailored to this population in order to enhance the feasibility of implementation and retention. If successful in reducing obesity and increasing healthy lifestyle choices to reduce diabetes, this study design can be implemented on a larger scale. TRIAL REGISTRATION: NCT02480244 . Registered 24 June 2015.

Physical activity and common tasks of California farm workers: California Heat Illness Prevention Study (CHIPS).

Farm workers are at risk of heat related illness (HRI), but their work rates that contribute to HRI have not been objectively assessed. The CHIPS study collected accelerometer data and characterized the physical activity of major farm tasks. Demographic information, work characteristics, and accelerometer data were collected from 575 farm workers in California. Each participating worker contributed measurements over one work shift. An Actical accelerometer was attached securely to a belt worn at the hip. Data were collected at one-minute intervals throughout the work shift. A total of 13 major work-task categories were defined. The mean physical activity counts per minute (cpm) and percentage of the shift spent at moderate and/or vigorous levels of activity were described for each task. Multiple linear regression models were constructed to determine the worker and environmental characteristics contributing to the physical activity level. Mean levels of physical activity ranged from 700 cpm (workers who carry produce) to a low of 150 cpm "ground pruners" who tend low-level plants, with an overall mean of 345 cpm or "light" activity (2 to ≤3 metabolic equivalents). The environmental temperature was the major factor associated with physical activity. A 10°C increase in the median temperature reduced the mean cpm by 135 (95% CI = 87, 193). Age and the tasks of sorting, ground pruning, and harvesting low-level crops were also negatively and independently associated with mean cpm. Incentivized (piece rate) pay, multi-task work, and irrigator work were positively associated with cpm. An interaction was found between piece rate and sex. Men's activity significantly increased (p < 0.001) by a mean of 95 cpm, (95% CI = 38.3, 150.7) if they were paid by the piece, but there was a non-significant association with women's activity level. Workers conducting multiple tasks, irrigators, men, and those earning incentivized (piece rate) pay had higher adjusted mean physical activity levels and are likely at increased risk of heat-related illness on hot days.

Personal exposure of dairy workers to dust, endotoxin, muramic acid, ergosterol, and ammonia on large-scale dairies in the high plains Western United States.

Dairy workers experience a high degree of bioaerosol exposure, composed of an array of biological and chemical constituents, which have been tied to adverse health effects. A better understanding of the variation in the magnitude and composition of exposures by task is needed to inform worker protection strategies. To characterize the levels and types of exposures, 115 dairy workers grouped into three task categories on nine farms in the high plains Western United States underwent personal monitoring for inhalable dust, endotoxin, 3-hydroxy fatty acids (3-OHFA), muramic acid, ergosterol, and ammonia through one work shift. Eighty-nine percent of dairy workers were exposed to endotoxin at concentrations exceeding the recommended exposure guidelines (adjusted for a long work shift). The proportion of workers with exposures exceeding recommended guidelines was lower for inhalable dust (12%), and ammonia (1%). Ergosterol exposures were only measurable on 28% of samples, primarily among medical workers and feed handlers. Milking parlor workers were exposed to significantly higher inhalable dust, endotoxin, 3-OHFA, ammonia, and muramic acid concentrations compared to workers performing other tasks. Development of large modern dairies has successfully made progress in reducing worker exposures and lung disease prevalence. However, exposure to endotoxin, dust, and ammonia continues to present a significant risk to worker health on North American dairies, especially for workers in milking parlors. This study was among the first to concurrently evaluate occupational exposure to assayable endotoxin (lipid A), 3-hydroxy fatty acids or 3-OHFA (a chemical measure of cell bound and noncell-bound endotoxins), muramic acid, ergosterol, and ammonia among workers on Western U.S. dairies. There remains a need for cost-effective, culturally acceptable intervention strategies integrated in OHS Risk Management and production systems to further optimize worker health and farm productivity.

Heat strain, volume depletion and kidney function in California agricultural workers.

BACKGROUND: Agricultural work can expose workers to increased risk of heat strain and volume depletion due to repeated exposures to high ambient temperatures, arduous physical exertion and limited rehydration. These risk factors may result in acute kidney injury (AKI). METHODS: We estimated AKI cumulative incidence in a convenience sample of 283 agricultural workers based on elevations of serum creatinine between preshift and postshift blood samples. Heat strain was assessed based on changes in core body temperature and heart rate. Volume depletion was assessed using changes in body mass over the work shift. Logistic regression models were used to estimate the associations of AKI with traditional risk factors (age, diabetes, hypertension and history of kidney disease) as well as with occupational risk factors (years in farm work, method of payment and farm task). RESULTS: 35 participants were characterised with incident AKI over the course of a work shift (12.3%). Workers who experienced heat strain had increased adjusted odds of AKI (1.34, 95% CI 1.04 to 1.74). Piece rate work was associated with 4.24 odds of AKI (95% CI 1.56 to 11.52). Females paid by the piece had 102.81 adjusted odds of AKI (95% CI 7.32 to 1443.20). DISCUSSION: Heat strain and piece rate work are associated with incident AKI after a single shift of agricultural work, though gender differences exist. Modifications to payment structures may help prevent AKI.

Hired farmworkers in the US: Demographics, work organisation, and services.

OBJECTIVE: Farm work is labor-intensive, physically demanding, and incurs a high risk of injury. The aim of this study was to identify characteristics of farmworkers at increased risk of adverse health outcomes to focus targeted interventions. METHODS: The National Agricultural Workers Survey for 2008-2012 was used to compare characteristics associated with adverse health and safety conditions among US-born and Mexican and Central American-born Latino and Indigenous, documented and undocumented farmworkers, separately for males and females. RESULTS: US-born farmworkers had more secure work, worked less onerous tasks, and earned more per hour than other categories of farmworkers. Undocumented Indigenous workers had more precarious work, worked more onerous tasks, and were more likely to do piece work, than undocumented Latino workers. DISCUSSION: We highlight disparities in modifiable occupational health risk factors across groups of farmworkers that are associated with increased risks of work-related injury and poor health. Am.

Cohort study of physical activity and injury among Latino farm workers.

INTRODUCTION: This study characterized physical activity and its association with injury among Latino farm workers. METHODS: An interviewer-administered questionnaire was used to collect baseline and follow-up data on 843 and 640 Latino farm workers, respectively. Participants were 18-55 years old, engaged in farm work and residing in Mendota, CA at baseline interview. The questionnaire assessed self-reported physical activity and risk of injury. RESULTS: The 12 month prevalence of injury decreased from 9.0% at baseline to 6.9% at follow up interview. In GEE models adjusted for age, follow-up time, gender, smoking, income and years working in agriculture, poor/fair self-assessed health status (OR = 1.82, 95% CI: 1.18-2.82) and 2-3 hr per day of sitting/watching TV/using a computer (OR = 0.50, 95% CI: 0.30-0.83) were significantly associated with injury. CONCLUSIONS: Physical activity was not associated with injury in this population. Efforts to reduce injuries should focus on known risk factors such as poor health status.

Concentrations of the urinary pyrethroid metabolite 3-phenoxybenzoic acid in farm worker families in the MICASA study.

Indoor pesticide exposure is a growing concern, particularly from pyrethroids, a commonly used class of pesticides. Pyrethroid concentrations may be especially high in homes of immigrant farm worker families who often live in close proximity to agricultural fields, and are faced with poor housing conditions, causing higher pest infestation and more pesticide use. We investigate exposure of farm worker families to pyrethroids in a study of mothers and children living in Mendota, CA within the population-based Mexican Immigration to California: Agricultural Safety and Acculturation (MICASA) Study. We present pyrethroid exposure based on an ELISA analysis of urinary metabolite 3-phenoxybenzoic acid (3PBA) levels among 105 women and 103 children. The median urinary 3PBA levels (children=2.56 ug/g creatinine, mothers=1.46 ug/g creatinine) were higher than those reported in population based studies for the United States general population, but similar to or lower than studies with known high levels of pyrethroid exposure. A positive association was evident between poor housing conditions and the urinary metabolite levels, showing that poor housing conditions are a contributing factor to the higher levels of 3PBA seen in the urine of these farm worker families. Further research is warranted to fully investigate sources of exposure.

Stress, Mental Health, and Coping Among Workers in the Northern California Cannabis Industry: A Qualitative Descriptive Analysis.

California is home to a multibillion-dollar cannabis (marijuana) industry, but little is known about the occupational health and safety hazards faced by cannabis workers and even less of the stress, mental health, and coping mechanisms among these workers. Previous research has been based on long-term workers at legal businesses, but most California cannabis is produced and sold unlawfully. There are many seasonal workers whose experiences have not been studied. A qualitative study based on focus group discussions and key informant interviews was performed to understand cannabis workers' experiences, knowledge, and perceptions of occupational hazards. Participants reported sources of stress including production pressure and isolation, and mental health outcomes such as depression and mental fatigue. They described primarily maladaptive coping mechanisms. Unique characteristics of the cannabis industry, including criminalization and isolated, remote farms, make interventions challenging. However, policy approaches that involve community organizations could promote worker health.

Adherence to dietary recommendations is associated with acculturation among Latino farm workers.

We examined adherence to dietary recommendations on fruit/vegetable and fat intake and identified correlates with acculturation indicators as well as with family, lifestyle, and occupational factors in a farm worker cohort in central California. Interviewer-administered questionnaires for this cross-sectional study were completed from January 2006 to April 2007. Participants were 18- to 55-y-old Latinos living in Mendota in a farm worker household. We assessed fruit/vegetable consumption and fat intake using the Block Fruit/Vegetable/Fiber Screener and the Block Dietary Fat Screener, respectively. Survey data analysis methods for contingency tables and logistic regression were used for assessing associations. The sample included 802 participants, reporting mean fruit and vegetable intake ( ± SD) of 5.0 ± 1.5 daily servings, and 47% reporting < 5 daily servings. Being born in Mexico or Central America and longer United States residency were associated with higher odds of consuming ≥ 5 daily fruit/vegetable servings and more frequent consumption of field products while working was associated with lower adherence to this recommendation. The average daily percent of calories from fat was 35.0 ± 4.1% and 53% of participants consumed > 35% of daily calories from fat. Men born in Mexico, women born in Central America, and participants who worked in fruit or vegetable crops had higher odds of consuming ≤ 35% of calories from fat. Higher acculturation level, United States school attendance, and having a child at home were associated with lower adherence to this recommendation. Acculturation, family, and occupational correlates of diet quality were identified in this underserved, immigrant population. Our findings may assist program targeting and intervention efforts.

Agricultural work and chronic musculoskeletal pain among Latino farm workers: the MICASA study.

BACKGROUND: Agriculture poses varied dangers to hired farm workers in the U.S., but little information exists on occupational risks for chronic musculoskeletal pain. We examined common work positions, such as kneeling, carrying heavy loads, and repetitive motion that may increase the risk for chronic musculoskeletal pain. METHODS: MICASA is a population-based study of occupational exposures and health in hired farm workers in California. This analysis includes 759 participants, 18-55 years old, engaged in farm work and residing in Mendota, CA. Chronic pain was defined as pain lasting 6 weeks or longer at specific body sites (back, knee, hip, etc.) over the entire farm work career. RESULTS: Mean age was 37.9 years. Sixty-five percent participants were born in Mexico, 27.7% were born in El Salvador, and 4.2% were U.S-born. Chronic pain was associated with older age and female sex. After adjustment for age, years working in agriculture, and smoking, stooping/bending >30 hr/week among both men (OR = 2.49, 95% CI: 1.03-5.99) and women (OR = 2.15, 95% CI: 1.04-4.46) was associated with chronic hip pain. Driving tractors or other heavy farm equipment >60 hr/week was associated with increased odds of chronic hip pain (OR = 2.16, 95% CI: 1.02-4.54) among men. We also observed significant associations with kneeling or crawling >35 hr/week among women for both chronic back pain (OR = 2.96, 95% CI: 1.27-6.93) and knee pain (OR = 3.02, 95% CI: 1.07-8.50), respectively. CONCLUSIONS: Chronic musculoskeletal pain is prevalent among farm workers and is associated with common work positions. Further research should focus on developing preventive interventions for tasks associated with increased pain risk. These interventions should be targeted to specific types of agricultural tasks.
