Abstract
BACKGROUND Several studies have documented poor housing conditions for farmworkers but none has focused on migrant farmworker housing, which is often provided as a condition of employment. Farmworker housing quality is regulated, but little documentation exists of compliance with regulations. METHODS A 2007 survey of 43 randomly selected farmworker camps and a 2008 survey of 27 camps randomly selected from the 2007 sample documented housing conditions via interviewer administered questionnaire and housing checklist. RESULTS Substandard conditions are common in migrant housing. All camps had at least one exterior housing problem; 93% had at least one interior problem. Housing conditions worsen across the agricultural season. Characteristics including no residents with H2A visa and 11 or more residents are associated with poorer conditions. CONCLUSIONS Housing standards are not adequately enforced. An increase in post-occupancy inspections and targeting camps with characteristics that place them at increased risk for substandard conditions are recommended.

Abstract
OBJECTIVES To quantify prevalence of dry mouth, association between dry mouth and beverage intake and dietary quality, and association between dry mouth and self-reported dietary accommodations to oral health deficits. DESIGN Cross-sectional study; data from self-reports. SETTING Rural North Carolina counties with substantial African-American and American Indian populations. PARTICIPANTS Six hundred twenty-two participants aged 60 and older. MEASUREMENTS Data included the 11-item Xerostomia Inventory (higher scores connote greater effect from dry mouth), a food frequency questionnaire (converted into Health Eating Index-2005 scores), and survey items on foods modified before consumption or avoided because of oral health problems. RESULTS Dry mouth was associated with being female, lower education, and income below the poverty level. Although overall beverage consumption did not vary with dry mouth, consumption of certain sugar-sweetened beverages was positively associated with dry mouth. Overall dietary quality did not differ with dry mouth, but more-severe dry mouth was associated with lower intake of whole grains and higher intakes of fruits. Dry mouth was strongly associated with self-reported modification and avoidance of foods. Those in the highest tertile of dry mouth were more likely to modify several foods than those in the lowest tertile and were more likely to avoid three or more foods. CONCLUSION Older adults appear to modify foods or selectively avoid foods in response to perceived dry mouth. Despite these behaviors, dry mouth does not result in poorer dietary quality.

Abstract
UNLABELLED OBJECTIVE. Evaluate similarities and differences in the self-care domain of health lifestyle among older, rural-dwelling women and men. METHOD Qualitative analysis of in-depth interview data from 62 community-dwelling older (M = 74.3 years) African and European American women and men. RESULTS Both older women and men rely heavily on over-the-counter medications and home remedies for self-care; professional health care is typically sought when self-care is not effective. However, relative to men, women were more knowledgeable about different approaches to self-care, especially home remedies; they used a wider range of self-care activities; and they placed greater priority on self-care over professional health care. DISCUSSION The structure of older women's and men's self-care domain of health lifestyle is similar. However, there are subtle differences in health lifestyle that are likely embedded in gendered role behavior and may contribute to women's greater health complaints.

Abstract
OBJECTIVE To investigate the importance of viewing belief systems about health maintenance holistically. METHODS Qualitative (N=74) and quantitative data (N=95) were obtained from a multi-ethnic rural-dwelling sample of older adults with diabetes to characterize their common sense models (CSMs) of diabetes. RESULTS There is a discrete number of CSMs held by older adults, each characterized by unique clusters of diabetes-related knowledge and beliefs. Individuals whose CSM was shaped by biomedical knowledge were better able to achieve glycemic control. CONCLUSIONS Viewing individuals' health beliefs incrementally or in a piece-meal strategy may be less effective for health behavior change than focusing on beliefs holistically.

Abstract
PURPOSE Blood glucose symptom recognition and the interpretation of how one feels with regard to low or high glucose can impact how diabetes is self-managed. Understanding interpretation of symptoms related to diabetes and ultimate glucose regulation can be challenging. Health care providers can develop strategies to improve care by listening to individuals describe their symptoms in the context of everyday life. METHODS The perspectives of older rural adults were assessed through individual in-depth interviews conducted among 75 African American, American Indian, and white individuals. The study design included a sample balanced with regard to sex, ethnicity, and educational attainment. The Self-Regulatory Model of Illness and the concept that people construct their own common sense models of health were utilized in this study. RESULTS There were four dominant themes of symptoms described that were related to blood glucose. These categories included sensations, lightheadedness, energy level, and eyesight changes. Participants described symptoms they experienced at perceived levels of both high and low blood glucose. Results suggest that older adults were unable to distinguish whether their symptoms occurred because of high or low blood glucose. CONCLUSION Education that incorporates methods to aid older individuals differentiate blood glucose levels related to diabetes symptoms could help improve self-management.

Abstract
BACKGROUND Environmental and biomedical researchers frequently encounter laboratory data constrained by a lower limit of detection (LOD). Commonly used methods to address these left-censored data, such as simple substitution of a constant for all values < LOD, may bias parameter estimation. In contrast, multiple imputation (MI) methods yield valid and robust parameter estimates and explicit imputed values for variables that can be analyzed as outcomes or predictors. OBJECTIVE In this article we expand distribution-based MI methods for left-censored data to a bivariate setting, specifically, a longitudinal study with biological measures at two points in time. METHODS We have presented the likelihood function for a bivariate normal distribution taking into account values < LOD as well as missing data assumed missing at random, and we use the estimated distributional parameters to impute values < LOD and to generate multiple plausible data sets for analysis by standard statistical methods. We conducted a simulation study to evaluate the sampling properties of the estimators, and we illustrate a practical application using data from the Community Participatory Approach to Measuring Farmworker Pesticide Exposure (PACE3) study to estimate associations between urinary acephate (APE) concentrations (indicating pesticide exposure) at two points in time and self-reported symptoms. RESULTS Simulation study results demonstrated that imputed and observed values together were consistent with the assumed and estimated underlying distribution. Our analysis of PACE3 data using MI to impute APE values < LOD showed that urinary APE concentration was significantly associated with potential pesticide poisoning symptoms. Results based on simple substitution methods were substantially different from those based on the MI method. CONCLUSIONS The distribution-based MI method is a valid and feasible approach to analyze bivariate data with values < LOD, especially when explicit values for the nondetections are needed. We recommend the use of this approach in environmental and biomedical research.

Abstract
This study categorizes older adults living in rural areas by denture status, assesses the frequency of wearing dentures during meals, and determines whether denture status or use is associated with dietary quality or the number of foods avoided. A multi-ethnic population-based sample of adults ≥60 years (N = 635) in the rural United States was interviewed. Survey included denture use, removing dentures before eating, and foods avoided due to oral health problems. Dietary intakes were converted into Healthy Eating Index-2005 scores. Sixty percent wore removable dentures of some type; 55% never, 27% sometimes, and 18% always removed dentures when eating. More frequent removal was associated with lower dietary quality and more foods avoided. Those with severe tooth loss had the lowest dietary quality and avoided the most foods. Many rural older adults wear dentures. Learning how they adapt to denture use will offer insight into their nutritional self-management and help explain differences in dietary quality.

Abstract
Respiratory health is an important component of the ability to perform physically demanding work. The authors assessed respiratory symptom prevalence among Latino farmworkers engaged in crop production, and investigated work activities as risk factors for respiratory symptoms. During June to September 2008, 122 farmworkers completed up to 3 questionnaires. The authors estimated associations between work activities and wheezing symptoms using alternating logistic regression, controlling for age and smoking. At the first data collection, 29 (24%) farmworkers reported ever wheezing and 10 (8%) reported wheezing within the past month. Though not statistically significant, the odds of wheezing were elevated for individuals who reported performing tobacco-related work in the last 3 days. The odds were decreased among individuals who reported harvesting activities (odds ratio: 0.3, 95% confidence interval: 0.1, 1.0). Among Latino farmworkers, respiratory symptoms may be associated with work activities.

Abstract
The goal of this study was to understand the potential threat of job stressors to farmworker health. To accomplish this goal we studied pesticide exposure, an issue with immediate and long-term health consequences, and predictions from the Demands-Control model of occupational stress. Longitudinal, self-report data and urine samples were collected at monthly intervals from a cohort of Latino farmworkers (N = 287) during the 2007 agricultural season. The primary hypothesis was that greater exposure to psychological demands, physical exertion, and hazardous work conditions are associated with greater odds of detecting dialkylphosphate (DAP) urinary pesticide metabolites, biomarkers indicating exposure to pesticides. Contrary to this hypothesis, results indicated that none of the elements of the Demands-Control model were independently associated with detection of DAP urinary pesticide metabolites. However, analyses produced several interaction effects, including evidence that high levels of control may buffer the effects of physical job demands on detection of DAP urinary pesticide metabolites.

Abstract
BACKGROUND Symptoms of occupational heat illness provide an early warning that workers are in potentially life-threatening environmental conditions. PURPOSE This analysis was designed to assess the extent to which strategies to reduce the health impact of extreme heat were associated with the prevalence of heat illness among Latino farm workers. METHODS Between June and September 2009, a total of 300 Latino men and women participated in a cross-sectional survey about farm worker health. Participants reported whether they were employed through the H-2A temporary agricultural worker program and whether they had ever worked in conditions of extreme heat during their work in the U.S. agricultural industry. Workers who had worked in extreme heat also responded to questions about selected activities and behaviors and whether they experienced symptoms of heat illness. Data analysis was conducted in 2009 to assess associations of altering work hours and activities, drinking more water, resting in shaded areas, and going to air-conditioned places during or after work, with the prevalence of symptoms of heat illness among H-2A and non-H-2A workers. RESULTS Working in extreme heat was reported by 281 respondents (94%), among whom 112 (40%) reported symptoms of heat illness. Changes in work hours and activities during hot conditions were associated with a lower prevalence of heat illness among H-2A workers but not among non-H-2A workers. CONCLUSIONS These findings suggest the need to improve the understanding of working conditions for farm workers and to assess strategies to reduce agricultural workers' environmental heat exposure.

Abstract
OBJECTIVE This article describes research designed to specify complementary therapies used among older adults by obtaining daily use data and the specific purposes for use. DESIGN Two hundred African American and White participants completed a baseline interview and up to six sets of three daily-diary interviews at monthly intervals. RESULTS Participants provided retrospective information on complementary therapy use and information on the use of therapies for specific symptoms experienced across 3,070 person days. Retrospective information indicated that most participants used complementary therapies (e.g., 85.0% used home remedies in the past year). The use of complementary or other therapies and the number of days the therapies were used varied for specific symptoms. For example, home remedies were used on 86 (9.1%) of the 944 person days for which joint pain was reported. DISCUSSION The daily-diary design provides detailed information for delineating how elders include complementary and other therapies in their health self-management.

Abstract
OBJECTIVES To examine the association between glycemic control and the executive functioning domain of cognition and to identify risk factors for inadequate glycemic control that may explain this relationship. DESIGN Cross-sectional study. SETTING In-person interviews conducted in participants' homes. PARTICIPANTS Ninety-five rural older African Americans, American Indians, and whites with diabetes mellitus (DM) from three counties in south-central North Carolina. MEASUREMENTS Participants underwent uniform evaluations. Glycemic control was measured using a validated method, and executive function was assessed using a previously established set of measures and scoring procedure. Information pertaining to medication for treatment of DM, knowledge of DM, and DM self-care behaviors were obtained. RESULTS In linear regression models adjusting for sex, age, education, ethnicity, duration of DM, and depressive symptoms, executive function was significantly associated with glycemic control. A 1-point higher executive function score was associated with a 0.47 lower glycosylated hemoglobin value (P=.01). The association between glycemic control and executive function became nonsignificant (P=.08) when controlling for several glycemic control risk factors, including use of DM medication and DM knowledge. CONCLUSION These results suggest that poor glycemic control is associated with impairments in performance on composite measures of executive function and that modifiable risk factors for glycemic control such as use of DM medication and DM knowledge may explain this relationship.

Abstract
PURPOSE OF THE STUDY This study identified approaches to diabetes self-management that differentiate persons with well-controlled from poorly controlled diabetes. Previous research has focused largely on persons participating in self-management interventions. DESIGN AND METHODS In-depth qualitative interviews were conducted with 48 adults, drawn from a population-based sample aged 65 years or older with diabetes. The sample was stratified by sex and ethnic group (African American, American Indian, and White) from the low (A1C <6%) and high (A1C >8%) extremes of the glycemic control distribution. Case-based text analysis was guided by a model, including six self-management domains and four resource types (self-care, informal support, formal services, and medical care). RESULTS A "structured" approach to self-management differentiated respondents in good glycemic control from those in poor glycemic control. Those in good glycemic control were more likely to practice specific food behaviors to limit food consumption and practice regular blood glucose monitoring with specific target values. This approach was facilitated by a greater use of home aides to assist with diabetes care. Respondents in poor glycemic control demonstrated less structure, naming general food categories and checking blood glucose in reaction to symptoms. IMPLICATIONS Results provide evidence that degree of structure differentiates self-management approaches of persons with good and poor glycemic control. Findings should provide a foundation for further research to develop effective self-management programs for older adults with diabetes.

Abstract
BACKGROUND Little is known about the HIV and sexually transmitted disease (STD) risk behaviors of Hispanic/Latino farmworkers. This study was designed to describe risk factors for HIV and STD infection, explore personal characteristics associated with condom use, and evaluate the feasibility of collecting self-report and biomarker data from farmworkers. METHODS Self-report and biomarker data were collected from a sample of male farmworkers living in 29 camps in North Carolina during the 2008 growing season. RESULTS Over half of the 100 male workers, mean age 37.1 (range 19-68) years, reported binge drinking during the past 12 months. Forty percent of those who reported having had sex during the past 3 months indicated that they were under the influence of alcohol. Knowledge of HIV and STD transmission and prevention was low. Among the 25 workers who reported having had sex during the past 3 months, 16 and 2 reported using a condom consistently during vaginal and anal sex, respectively, and nearly 1 out of 6 workers reported paying a woman to have sex. Two workers tested positive for syphilis. CONCLUSIONS Farmworkers in this sample demonstrated significant HIV and STD risks; however, when exploring potential bivariate associations with consistent condom use no statistically significant associations were identified perhaps due to the small sample size. Because it was feasible to collect self-report and biomarker data related to HIV and STDs from Hispanic/Latino farmworkers, research needed to further explore risks and develop interventions to reduce disease exposure and transmission among this vulnerable population.

Abstract
BACKGROUND Organophosphate pesticides act as cholinesterase inhibitors. For those with agricultural exposure to these chemicals, risk of potential exposure-related health effects may be modified by genetic variability in cholinesterase metabolism. Cholinesterase activity is a useful, indirect measurement of pesticide exposure, especially in high-risk individuals such as farmworkers. To understand fully the links between pesticide exposure and potential human disease, analyses must be able to consider genetic variability in pesticide metabolism. OBJECTIVES We studied participants in the Community Participatory Approach to Measuring Farmworker Pesticide Exposure (PACE3) study to determine whether cholinesterase levels are associated with single-nucleotide polymorphisms (SNPs) involved in pesticide metabolism. METHODS Cholinesterase levels were measured from blood samples taken from 287 PACE3 participants at up to four time points during the 2007 growing season. We performed association tests of cholinesterase levels and 256 SNPs in 30 candidate genes potentially involved in pesticide metabolism. A false discovery rate (FDR) p-value was used to account for multiple testing. RESULTS Thirty-five SNPs were associated (unadjusted p < 0.05) based on at least one of the genetic models tested (general, additive, dominant, and recessive). The strongest evidence of association with cholinesterase levels was observed with two SNPs, rs2668207 and rs2048493, in the butyrylcholinesterase (BCHE) gene (FDR adjusted p = 0.15 for both; unadjusted p = 0.00098 and 0.00068, respectively). In participants with at least one minor allele, cholinesterase levels were lower by 4.3-9.5% at all time points, consistent with an effect that is independent of pesticide exposure. CONCLUSIONS Common genetic variation in the BCHE gene may contribute to subtle changes in cholinesterase levels.

Abstract
Involving students in community-based participatory research is a useful mechanism for engaging the community and helping it build future capacity. This article describes student involvement in a series of community-based environmental health research projects with migrant and seasonal farmworkers in North Carolina. High school, undergraduate, graduate, and professional school students have participated in various aspects of these projects, including planning, data collection, analysis, and reporting results. Students were required to invest time in learning about the farmworker population, as well as in learning to conduct community-based environmental health research. Drawing on these experiences, we offer observations regarding successful student integration in this type of research. Community-based projects benefit from student participation while encouraging the development of future community-oriented environmental health researchers.

Abstract
BACKGROUND Limited data document the multiple and repeated pesticide absorption experienced by farmworkers in an agricultural season or their risk factors. METHODS Data were collected from 196 farmworkers four times at monthly intervals in 2007. Urine samples were tested for 12 pesticide urinary metabolites. Questionnaire data provided measures of exposure risks. RESULTS Farmworkers had at least one detection for many pesticide urinary metabolites; for example, 84.2% had at least one detection for acephate, 88.8% for 3,5,6-trichloro-2-pyridinol. Most farmworkers had multiple detections for specific metabolites; for example, 64.8% had two or more detections for acephate, 64.8% for 3,5,6-trichloro-2-pyridinol, 79.1% for 3-phenoxybenzoic acid, and 86.7% for 2,4-dichlorophenoxyacetic acid. Housing type had a consistent significant association with metabolite detections. CONCLUSIONS Farmworkers are exposed to multiple pesticides across an agricultural season, and they experience repeated exposures to the same pesticides. Reducing farmworker pesticide exposure and delineating the health outcomes of this exposure require more detailed data. Am. J. Ind. Med. 53:802-813, 2010. (c) 2010 Wiley-Liss, Inc.

Abstract
The workforce in all areas of United States agriculture and forestry is becoming increasingly diverse in language, culture, and education. Many agricultural workers are immigrants who have limited English language skills and limited educational attainment. Providing safety and health training to this large, diverse, dispersed, and often transient population of workers is challenging. This review, prepared for the 2010 Agricultural Safety and Health Council of America/National Institute for Occupational Safety and Health conference, "Be Safe, Be Profitable: Protecting Workers in Agriculture," is divided into five sections. First, we describe the occupational and demographic characteristics of agricultural workers in the United States to highlight their safety and health training needs. Second, we summarize current research on the social and cultural attributes of agricultural workers and agricultural employers that affect the provision of safety and health training. Worker and employer attributes include language, literacy, financial limitations, work beliefs, and health beliefs. Third, we review current initiatives addressing safety and health training for agricultural workers that consider worker language and literacy. These initiatives are limited to a few specific topics (e.g., pesticides, heat stress); they do not provide general programs of safety training that would help establish a culture of workplace safety. However, several innovative approaches to health and safety training are being implemented, including the use of community-based participatory approaches and lay health promoter programs. Fourth, the limited industry response for safety training with this linguistically diverse and educationally limited workforce is summarized. Finally, gaps in knowledge and practice are summarized and recommendations to develop educationally, culturally, and linguistically appropriate safety and health training are presented.

Abstract
The mental health of Latinos immigrating to nontraditional settlements may be compromised by limited contextual resources. Stressors and strengths related to anxiety and depression were examined among 150 Mexican adults (45.3% women) in nontraditional areas. Normative stress was associated with anxiety (beta = .24) after controlling for depression. Normative and acculturative stressors were associated with depression after controlling for anxiety (betas = .36 and .17, respectively). Links between normative stress and depression were particularly strong for women. Social support provided resilience, being linked with lower depression (beta = -.20, p < .01). Acculturative stress and meeting economic expectations were associated with greater depression, but only for recent immigrants. Acculturative and normative stress increased the odds of clinical caseness for comorbidity by 4% and 62%, respectively, whereas social support decreased risk. Contextual implications and the need for resources to aid cultural adaptation are discussed.

Abstract
Immigrant Latino farmworkers confront multiple challenges that threaten their mental health. Previous farmworker mental health research has relied primarily on cross-sectional study designs, leaving little opportunity to describe how farmworker mental health changes or to identify factors that may contribute to these changes. This study used prospective data obtained at monthly intervals across one 4-month agricultural season from a large sample of Latino farmworkers in North Carolina (N = 288) to document variation in depressive symptoms across the agricultural season and delineate structural and situational factors associated with mental health trajectories across time. Depressive symptoms generally followed a U-shaped distribution across the season, but there was substantial variation in this pattern. Structural stressors like marital status and situational stressors like the pace of work, crowded living conditions, and concerns about documentation predicted depressive symptoms. The pattern of results suggests that strategies to address mental health problems in this vulnerable population will require coordinated action at the individual and social level.

Abstract
OBJECTIVES To quantify the association between food avoidance and modification due to oral health problems, to examine the association between food practices and dietary quality, and to determine foods associated with these self-management behaviors. DESIGN Cross-sectional. SETTING Rural North Carolina. PARTICIPANTS Six hundred thirty-five community-dwelling adults aged 60 and older. MEASUREMENTS Demographic and food frequency data and oral health assessments were obtained during home visits. Avoidance (0, 1-2 foods, 3-14 foods) and modification (0-3 foods, 4-5 foods) due to oral health problems were assessed for foods representing oral health challenges. Food frequency data were converted into Healthy Eating Index-2005 (HEI-2005) scores. Linear regression models tested the significance of associations between HEI-2005 measures and food avoidance and modification. RESULTS Thirty-five percent of participants avoided three to 14 foods, and 28% modified four to five foods. After adjusting for age, sex, ethnicity, poverty, education, and tooth loss, total HEI-2005 score was lower (P<.001) for persons avoiding more foods and higher for persons modifying more foods (P<.001). Those avoiding three to 14 foods consumed more saturated fat and energy from solid fat and added sugar and less nonhydrogenated fat than those avoiding fewer than three foods. Those who modified four to five foods consumed less saturated fat and solid fat and added sugar but more total grains than those modifying fewer than four foods. CONCLUSION Food avoidance and modification due to oral health problems are associated with significant differences in dietary quality. Approaches to minimize food avoidance and promote food modification by persons having eating difficulties due to oral health conditions are needed.

Abstract
BACKGROUND Farmworkers can be exposed to a wide variety of pesticides. Assessing cholinesterase activity over time can be used to monitor exposure to organophosphorus and carbamate pesticides. OBJECTIVES The goal of this study was to document patterns and variation in cholinesterase levels across the agricultural season (May-August) among field-workers, and to explore the association of cholinesterase depression with pesticide exposure across the agricultural season. METHODS Dried blood samples collected from 231 migrant farmworkers sampled from camps in eastern North Carolina up to four times across a summer agricultural season were analyzed for cholinesterase activity, and urine samples were analyzed for metabolites of organophosphorus and carbamate pesticides. Reductions of >or= 15% from an individual's highest value were identified and considered evidence of meaningful cholinesterase activity depression. RESULTS The average cholinesterase activity levels were lowest in June, with significantly higher mean values in July and August. When adjusted for age, sex, minutes waited to shower, and days worked in the fields, the number of organophosphorus and carbamate pesticides detected in urine predicted reductions in cholinesterase activity. CONCLUSIONS These data demonstrate that workers are experiencing pesticide exposure. Greater enforcement of existing safety regulations or strengthening of these regulations may be warranted. This study demonstrates that serial measurements of cholinesterase activity across an agricultural season can detect exposure to pesticides among field-workers.

Abstract
CONTEXT Rural patients have limited access to dermatologic care. Farmworkers have high rates of skin disease and limited access to care. PURPOSE This exploratory study assessed whether teledermatology consultations could help meet the needs of health care providers for farmworkers in rural clinics. METHODS Dermatologists provided 79 consultations, using store-and-forward teledermatology, to farmworkers who presented with a skin disease to rural North Carolina clinics. Clinic providers rated the value of the consultation. FINDINGS Most requests for consultations (94%) came from family nurse practitioners or physician assistants. Twelve percent of consultations were rated somewhat helpful, and the remainder helpful or very helpful. After receiving the consultation, providers changed the diagnosis in 13% of cases. The consultation led providers to contact or attempt to contact 21% of patients to change treatment recommendations. CONCLUSIONS Access to expert dermatologic services is needed by rural health care providers. Teledermatology consultations may be a helpful tool to meet this need.

Abstract
OBJECTIVES To assess the association of depressive symptoms with diabetes self-management regimens among older adults with type 2 diabetes in a rural, ethnically diverse community. METHODS Data from 696 rural older African Americans, American Indians, and whites were used to assess depressive symptoms (modified CES-D) and diabetes self-management (physical activity, blood glucose self-monitoring, self foot checks, following a healthful eating plan, and medication adherence). RESULTS In bivariate analyses, high CES-D scores were associated with decreased adherence to a healthful eating plan and physical activity and increased foot checks; the latter 2 remained significant in multivariate analyses. CONCLUSIONS Older adults with diabetes and depression are less likely to adhere to self-management, increasing their risk of complications.

Abstract
BACKGROUND Immigrant farmworkers are a population at risk for numerous environmental and occupational exposures. The metals arsenic, lead, mercury, and cadmium are known neurotoxins to which workers can be exposed both in the US and in their country of origin. Because farmworkers are exposed to neurotoxic pesticides, they may be at risk for adverse health effects from the combined exposure. OBJECTIVES To examine the relationship between exposure to metals, as measured in urine, with personal and work-related characteristics of Mexican migrant and seasonal farmworkers in the US. METHODS We analyzed data on metals found in urine of 258 farmworkers recruited from 44 camps in eastern North Carolina in 2007. Geometric means and 95% confidence intervals (CI) were used to compare data with data from the National Health and Nutrition Examination Survey (NHANES). We used multivariate regression models fitted for each metal to estimate the association of creatinine-corrected urinary metals and worker characteristics related to environmental and occupational exposures. RESULTS Geometric mean urinary metals concentrations (mug/g creatinine) exceeded NHANES reference values for arsenic (13.23 [CI 11.11, 15.35] vs. 8.55 [CI 7.23, 9.86]) and lead (1.26 [CI 1.08, 1.43] vs. 0.63 [CI 0.60, 0.66]). Age, being from the central region of Mexico, and pack years of cigarette smoking were significant predictors of metals exposure; being a current smoker and years worked in US agriculture were not. CONCLUSIONS This first study to examine indicators of worker body burdens of metals shows that workers have body burdens related to exposures other than work in the US. Further research should address their risk for adverse health outcomes due to combined exposures to neurotoxins in pesticides.

Abstract
The 2005 Dietary Guidelines for Americans publication placed increased emphasis on the importance of consuming a wide range of healthful foods and further reducing the consumption of less healthful ones. These recommendations are challenging for rural elders whose functional limitations, fewer resources, and limited access to foods negatively affect the quality of their diets. The purpose of this study was to characterize the diet quality of a multiethnic population-based sample of older adults (N=635) in the southern United States. Data were collected via home visit; dietary intakes were assessed using a food frequency questionnaire and converted into Healthy Eating Index-2005 (HEI-2005) scores used to monitor adherence to dietary guidelines. The mean total HEI-2005 score was 61.9/100 with fewer than 2% meeting the recommended score of 80/100. After controlling for age, sex, marital status, poverty status, and education, African Americans (n=136) had higher total HEI-2005 scores compared to American Indians (n=195) and non-Hispanic whites (n=304) (64.5 vs 60.1 and 61.1 respectively, P=0.001). Certain HEI-2005 foods were consumed in greater amounts by particular groups, such as total fruit and meat and beans (African Americans), whole fruit and grains (African Americans and American Indians), milk (non-Hispanic whites), and energy from solid fat, alcohol, and added sugars (American Indians). The overall diet quality of these rural elders was not adequate as determined by the HEI-2005; however, intakes of dark green and orange vegetables were adequate, and many participants were in compliance with the added fat and sugar guidelines. Determination of factors that promote or prevent the consumption of healthful foods among rural elders may help tailor nutrition education programs for these vulnerable communities.

Abstract
This analysis describes the detection of urinary pesticide metabolites for Latino farmworkers across the agricultural season. Two hundred and eighty four farmworkers were recruited from 44 camps in eastern North Carolina in 2007. Data were collected at one month intervals for a total of 939 data points. The OP insecticide metabolites 3,5,6-trichloropyridinol (46.2%), malathion dicarboxylic acid (27.7%), and para-nitrophenol (97.4%); the pyrethroid metabolite 3-phenoxybenzoic acid (56.4%); and the herbicides 2,4-D (68.1%), acetochlor (29.2%), and metolachlor (16.9%) were found in sizable percentages of the samples. The percentage of farmworkers for whom metabolites were detected varied across the agricultural season. None of the farmworker characteristics were significantly associated with the detection of any pesticide metabolite. Seasonality overrides the effects of other farmworker characteristics in predicting detection of pesticide urinary metabolites. Future research needs to collect multiple exposure measures at frequent intervals over an extended period to characterize factors associated with exposure.

Abstract
OBJECTIVES To compare oral health status according to ethnicity and socioeconomic status in African-American, American-Indian, and white dentate and edentulous community-dwelling older adults. DESIGN Cross-sectional study; data from self-reports and oral examinations. PARTICIPANTS A multistage cluster sampling design was used to recruit 635 participants aged 60 and older from rural North Carolina counties with substantial African-American and American-Indian populations. MEASUREMENTS Participants completed in-home interviews and oral examinations. Self-reported data included sociodemographic indicators; self-rated oral health status; presence or absence of periodontal disease, bleeding gums, oral pain, dry mouth; and fit of prostheses. Oral examination data included number of teeth and numbers of anterior and posterior functional occlusal units. RESULTS African Americans and American Indians had significantly lower incomes and educational attainment than whites. Self-rated oral health was significantly better in whites than in African Americans and American Indians. Prevalence of self-reported periodontal disease and bleeding gums was lower in whites. Of dentate participants, African Americans were significantly more likely than whites to have 11 to 20 teeth and one or two posterior occlusal contacts. Oral health deficits remained associated with ethnicity when adjusted for socioeconomic variables. CONCLUSION Oral health disparities in older adults in a multiethnic rural area were largely associated with ethnicity and not socioeconomic status. Clinicians should be aware of these health disparities in oral health status and their possible role in disparities in chronic disease. Further research is necessary to understand whether these oral health disparities reflect current or lifetime access to care, diet, or attitudes toward oral health care.

Abstract
PURPOSE Dietary variation is important for health maintenance and disease prevention among older adults. However, oral health deficits impair ability to bite and chew foods. This study examines the association between oral health and foods avoided or modified in a multiethnic rural population of older adults. It considers implications for nutrition and medical service provision to this population. DESIGN AND METHODS In-home interviews and oral examinations were conducted with 635 adults in rural North Carolina counties with substantial African American and American Indian populations. Avoidance and modification data were obtained for foods representing different dental challenges and dietary contributions. Data were weighted to census data for ethnicity and sex. Bivariate analyses of oral health measures and foods avoided used chi-square and logistic regression tests. Multivariable analyses used proportional odds or nominal regression models. RESULTS Whole fruits and raw vegetables were the most commonly avoided foods; substantial proportions of older adults also avoided meats, cooked vegetables, and other foods. Food avoidance was significantly associated with self-rated oral health, periodontal disease, bleeding gums, dry mouth, having dentures, and having fewer anterior and posterior occlusal contacts. Associations persisted when controlling for demographic and socioeconomic status indicators. From 24% to 68% of participants reported modifying specific fruits, vegetables, and meats. Modifying harder foods was related to location of teeth and periodontal disease and softer foods to oral pain and dry mouth. IMPLICATIONS Food services for older adults should consider their oral health status. Policy changes are needed to provide oral health care in benefits for older adults.

Abstract
BACKGROUND Community Participatory Approach to Measuring Farmworker Pesticide Exposure, PACE3, used a longitudinal design to document pesticide biomarkers among farmworkers. This article presents an overview of PACE3 and provides a descriptive analysis of participant characteristics and one set of pesticide biomarkers, the dialkylphosphate (DAP) urinary metabolites of organophosphorus (OP) pesticides. METHODS Two hundred eighty seven farmworkers were recruited during 2007 from 44 farmworker camps in 11 eastern North Carolina counties. Participants provided interviews, urine samples, blood samples, and saliva samples up to four times at monthly intervals beginning in May. A total of 939 data points were collected. RESULTS Farmworkers were largely men (91.3%) from Mexico (94.8%) with a mean age of 33.7 years (SE 0.82); 23.3% spoke an indigenous language. Across all data points, frequencies of detection and median urinary concentrations were 41.3% and 0.96 microg/L for dimethylphosphate (DMP), 78.3% and 3.61 microg/L for dimethylthiophosphate (DMTP), 33.3% and 0.04 microg/L for dimethyldithiophosphate (DMDTP), 40.5% and 0.87 microg/L for diethylphosphate (DEP), 32.3% and 0.17 microg/L for diethylthiophosphate (DETP), and 8.09% and 0.00 microg/L for diethyldithiophosphate (DEDTP). The frequencies of detection and urinary concentrations of the DAP metabolites increased during the season. CONCLUSIONS More PACE3 participants were from Mexico, male, migrant workers, and spoke an indigenous language compared to national data. PACE3 participants had comparable frequencies of detection and urinary metabolite concentrations with participants in other studies. Variability in the frequencies of detection and urinary concentrations of the DAP metabolites indicates the importance of longitudinal studies of biomarkers of currently used pesticides in farmworker populations.

Abstract
We evaluated a lay health promoter program providing occupational health and safety education to immigrant Latino poultry processing workers in western North Carolina. While such programs are advocated for addressing the health education deficits of immigrant and disadvantaged populations, their application in occupational health has been limited to farmworkers. A community-university partnership recruited and trained promoters to deliver lessons on musculoskeletal injuries, slips and falls, and workers' rights to workers individually or in small groups in the community. Evaluation showed 841 workers received education during a 28-month period. Using ethnographic data, an evaluation showed that promoters' work led to changes in behavior and attitudes in the community. Promoters also reported substantial changes in self-esteem and independence. Promoters' supervisors reported challenges and strategies experienced by the promoters. Promoter programs in occupational health and safety are feasible approaches to supplement training provided in the workplace.

Abstract
The goal of this analysis is to evaluate the effectiveness of a promotora program for teaching women in Latino farmworker families about pesticide safety and increasing pesticide safety behaviors. Volunteer promotoras delivered a pesticide safety curriculum (intervention) and nutrition curriculum (control) to farmworker women residing in western North Carolina and Virginia. Pre-and postintervention interviews assessed differences in delivery of the intervention, recognition of the intervention, pesticide knowledge, pesticide exposures behaviors, and integrated pest management behaviors. Participants in the intervention group reported significantly more receipt of pesticide education and greater recognition of the key messages. However, their knowledge, pesticide exposure behaviors, and integrated pest management behaviors did not change. A more structured program is needed to be sure that the dose of interventions is large enough to overcome educational and cultural characteristics of immigrant communities. Policy changes are needed to address circumstances outside of farmworkers' control that affect pesticide exposure.

Abstract
CONTEXT Skin diseases are common occupational illnesses for migrant farmworkers. Farmworkers face many barriers in accessing health care resources. PURPOSE Framed by the Health Behavior Model, the purpose of this study was to assess health care utilization for skin disease by migrant Latino farmworkers. METHODS Three hundred and four migrant and seasonal Latino farmworkers in North Carolina were enrolled in a longitudinal study of skin disease and health care utilization over a single agricultural season. Self-reported and dermatologist-diagnosed skin condition data were collected at baseline and at up to 4 follow-up assessments. Medical visit rates were compared to national norms. FINDINGS Self-reported skin problems and diagnosed skin disease were common among farmworkers. However, only 34 health care visits were reported across the entire agricultural season, and none of the visits were for skin diseases. Nevertheless, self-treatment for skin conditions was common, including use of non-prescription preparations (63%), prescription products (9%), and home remedies (6%). General medical office visits were reported in 3.2% of the assessments, corresponding to 1.6 office visits per person year. CONCLUSIONS The migrant farmworker population consists largely of young men who make little use of clinic services. Skin conditions are very common among these workers, but use of medical services for these conditions is not common. Instead, farmworkers rely primarily on self-treatment. Clinic-based studies of farmworker skin conditions will not account for most injury or disease in this population and have the potential for biased estimates.

Abstract
BACKGROUND Melasma is a common condition of Latino women that detracts from their quality of life (QOL). The prevalence and impact of melasma in Latino men is not well characterized. AIM To assess the prevalence of melasma and its association with QOL in Latino men from Mexico and Central America working in the USA. METHODS The prevalence of melasma was assessed in three studies of Latino men: by direct examination in a study of 25 Latino poultry workers; by direct examination in a study of 54 Latino farm workers; and by examination of store-and-forward teledermatology images in a study of 300 Latino farm workers. QOL was assessed with a Spanish version of the Dermatology Life Quality Index (DLQI). RESULTS The prevalence of melasma was 36.0%, 7.4%, and 14.0% in the three studies. The prevalence of melasma was greatest amongst those aged 31 years and older, who were from Guatemala, and who spoke an indigenous language. The presence of melasma was associated with higher DLQI scores, indicating a poorer QOL, in the poultry worker population. CONCLUSIONS Melasma is a common condition in Latino men and is associated with a poor QOL in some affected individuals. Clinicians should be aware that melasma may be a concern for their male Latino patients. Research on the association of skin conditions with QOL amongst minority men is needed.

Abstract
OBJECTIVES Existing studies on the use of complementary and alternative medicine (CAM) have produced diverse results regarding the types and prevalence of CAM use due, in part, to variations in the measurement of CAM modalities. A questionnaire that can be adapted for use in a variety of populations will improve CAM utilization measurement. The purposes of this article are to (1) articulate the need for such a common questionnaire; (2) describe the process of questionnaire development; (3) present a model questionnaire with core questions; and (4) suggest standard techniques for adapting the questionnaire to different languages and populations. METHODS An international workshop sponsored by the National Research Center in Complementary and Alternative Medicine (NAFKAM) of the University of Tromsø, Norway, brought CAM researchers and practitioners together to design an international CAM questionnaire (I-CAM-Q). Existing questionnaires were critiqued, and working groups drafted content for a new questionnaire. A smaller working group completed, tested, and revised this self-administered questionnaire. RESULTS The questionnaire that was developed contains four sections concerned with visits to health care providers, complementary treatments received from physicians, use of herbal medicine and dietary supplements, and self-help practices. A priori-specified practitioners, therapies, supplements, and practices are included, as well as places for researcher-specified and respondent-specified additions. Core questions are designed to elicit frequency of use, purpose (treatment of acute or chronic conditions, and health maintenance), and satisfaction. A penultimate version underwent pretesting with "think-aloud" techniques to identify problems related to meaning and format. The final questionnaire is presented, with suggestions for testing and translating. CONCLUSIONS Once validated in English and non-English speaking populations, the I-CAM-Q will provide an opportunity for researchers to gather comparable data in studies conducted in different populations. Such data will increase knowledge about the epidemiology of CAM use and provide the foundation for evidence-based comparisons at an international level.

Abstract
Dietary self-management of diabetes is often difficult for older adults to practice, particularly in rural communities. We describe patterns and correlates of dietary fat reduction among older rural adults with diabetes of any type. In-home interviews were conducted with a multiethnic random sample of 701 adults ≥ 65 with diabetes from two North Carolina counties. The Fat and Fiber Behavior Questionnaire was used to measure dietary behaviors. Separate multiple linear regressions assessed effects of gender, ethnicity, and diabetes education. In general, scores were more favorable for practices that involved modifying food preparation (e.g., avoiding frying) and less favorable for practices that involved changing foods consumed (e.g., substituting fruits and vegetables as desserts or snacks). American Indians and African Americans had less favorable scores than whites, and diabetes education was associated with greater fat restriction for women than men. Older men and ethnic minorities with diabetes should be targeted for dietary change education.

Abstract
OBJECTIVES This article describes dimensions of complementary therapy use among rural older adults, employs these dimensions to delineate sets of complementary therapy use, and describes the personal characteristics related to each set of complementary therapy use. METHODS Data are from in-depth interviews conducted with 62 African American and White rural older adults. RESULTS Three dimensions of complementary therapy use are delineated: types of therapies used, mindfulness in therapy use, and sharing information with conventional health care providers. The intersection of these dimensions indicates 5 patterned sets of complementary therapy use among rural older adults: (a) mindful use of only home remedies; (b) mindful use of home remedies and contemporary supplements; (c) mindful use of home remedies, contemporary supplements, and complementary practices; (d) nonmindful use of home remedies and contemporary supplements; and (e) use of conventional care only. Involvement in the 5 sets of therapy use is related to sex, ethnicity, educational attainment, and migration. DISCUSSION Understanding how older adults include sets of complementary therapies in their health self-management is important for improving their health care resources, expectations, awareness, and priorities.

Abstract
Lay Health Promoters (LHPs) are widely used in community health education, but their use and evaluation in occupational health has been limited to farm workers. Evaluation data were collected from 30 randomly selected Latino poultry processing workers who had an encounter with an LHP who delivered Maria's Story, an occupational health lesson about cumulative trauma disorders (CTDs). Participants had good recall of Maria's Story. Most participants (n = 18, 60%) could identify the primary occupational health exposure linked to CTDs, more than 50% of participants (n = 16) could recall one or more ways of preventing CTDs, and 43.3% (n = 13) described in detail recommended treatments. Nearly one-half (n = 12) reported an occupational health behavior change after hearing Maria's Story. The results of this study suggest that LHPs may be effective in promoting occupational health and reducing occupational health disparities among ethnic minorities in high-risk occupations.

Abstract
BACKGROUND Over 250,000 workers are employed in poultry processing, one of the most dangerous industries in the US. These jobs are increasingly held by immigrant workers who are frequently undocumented, lack knowledge of workers' rights to workplace safety, and who are reluctant to pursue their rights. This situation creates the potential for organizational injustice, made visible through abusive supervisory practices, and leads to situations in which occupational illnesses and injuries are likely to occur. METHODS This paper draws on data collected during the research phases of a community-based participatory research and social justice project. Two hundred survey interviews and 26 in-depth interviews were collected in representative, community-based samples in western North Carolina. Analyses describe associations between one aspect of organizational injustice, abusive supervision, and worker injuries. RESULTS Workers' reports of abusive supervision are associated with a variety of specific and summary health indicators. The associations are stronger for women than for men. These suggest that the use of relative power within the plant may be the basis for injuries and illnesses. Three types of power relations are described that form the basis for these abusive interactions in the plant: ethnicity (American vs. Latino), immigration status ("good papers" vs. undocumented), and rank (supervisor vs. worker). Two factors modify these relations: kinship (preferences and privileges for family members) and gender. CONCLUSIONS Among Latino immigrants working in poultry plants, power differences reflecting organizational injustice in the form of abusive supervision may promote occupational illnesses and injuries, particularly for women.

Abstract
OBJECTIVE African American men die from prostate cancer at higher rates than do White men, a health disparity that may result from differences in knowledge and beliefs about prostate cancer and screening. Studies conflict on whether race or socioeconomic status affects knowledge of prostate cancer and screening. This study compared education, race, and screening status to determine how each factor shapes men's knowledge of prostate cancer and screening. METHODS In-depth interviews were conducted with 65 African American and White men, aged 40-64 years, with diverse educational backgrounds. RESULTS Education, not race or screening status, was associated with knowledge about the prostate gland, prostate cancer symptoms and screening tests, and fear of prostate cancer. The exception was knowledge about the prostate-specific antigen blood test, which was associated with education and screening status. CONCLUSION This study suggests that education may be associated with prostate cancer and screening knowledge. Interventions should focus on all men with low education to correct their misconceptions about prostate cancer and to engage them in shared decision-making about screening.

Abstract
OBJECTIVES To describe beliefs about hypertension and health education of young African American adults varying in their hypertension risk status. DESIGN Fifty-eight African American young adults (17-20 years) were selected based on low and high risk criteria for hypertension assessed in earlier investigations of hemodynamic responses to stress. The sample included 15 high risk males, 13 low risk males, 14 high risk females, and 16 low risk females who were interviewed indepth about their hypertension beliefs and health education experiences. Variable-based matrices identified participants with similar responses. RESULTS Overall, participants had a limited understanding of hypertension. For example, they linked the condition to eating a diet high in pork and fat and having a positive family history of hypertension with little acknowledgement of weight, smoking, race and sex as key contributors to hypertension onset. Distinctions were found between risk categories and along sex lines. Most high risk participants believed stress could cause hypertension. High risk females believed that they were at risk for developing hypertension but lacked prevention strategies. High risk males were generally uninformed about risk or prevention. More low risk females believed in prevention compared to few low risk males. Participants reported little formal health education about hypertension and recommended that hypertension education be improved through more effective and relevant approaches in high school health education classes. CONCLUSIONS These findings support the need for comprehensive and revitalized hypertension prevention programs for young African Americans. Participant views varied with hypertension risk status and gender suggesting that targeted educational efforts should reflect these differences.

Abstract
OBJECTIVES This analysis describes the dental self-care behaviors used by a multiethnic sample of older adults and delineates the associations of self-care behaviors with personal characteristics and oral health problems. METHODS A cross-sectional comprehensive oral health survey conducted with a random, multiethnic (African-American, American Indian, white) sample of 635 community-dwelling rural adults aged 60 years and older was completed in two rural southern counties. RESULTS Rural older adults engage in a variety of self-care behaviors, including the use of over-the-counter (OTC) medicine (12.1 percent), OTC dental products (84.0 percent), salt (50.9 percent), prayer (6.1 percent), and complementary therapies (18.2 percent). Some gender and ethnic class differences are apparent, with greater use by women of OTC medicine and salt and greater use by African-Americans and American Indians of OTC medicine and OTC dental products. The use of dental self-care behaviors appears to be driven by need. Those reporting oral pain, bleeding gums, and dry mouth have greater odds of engaging in most of the dental self-care behaviors, including the use of complementary therapies. CONCLUSIONS The major factor leading to the use of self-care behaviors is need. Although oral pain does increase the use of self-care behaviors, so do bleeding gums and dry mouth. Research and practice should address self-care behaviors used for oral health problems in addition to pain. Investigators should expand analysis of dental self-care behavior and the relationship of self-care behavior to the use of professional services. Further research also should explore the use of complementary therapies in dental self-care.

Abstract
Migrant farmworkers are exposed to numerous workplace hazards, with pesticides being a ubiquitous occupational exposure. This analysis describes farmworker experiences of field and camp safety conditions and their safety behaviors, and delineates farmworker characteristics associated with safety conditions and behaviors. Data were collected from 255 migrant farmworkers up to 4 times at monthly intervals during the 2007 agricultural season in eastern North Carolina. Measures assess field safety conditions and camp sanitation required by federal and state regulations. Most of the farmworkers were Latino men from Mexico. About 20% had not received pesticide safety training across the season; many of those who received such training did not understand it. Water for washing was not available for about one-third of the workers; soap and towels were not available for over half. About 20% lived in camps with more than eight workers per showerhead and about 20% lived in camps that failed to meet the standard of 30 or fewer workers per washtub/washing machine. Important predictors of variation included H2A visa status and years of experience. Four themes emerged from the analysis: (1) safety regulations are not consistently met; (2) farmworkers do not always practice safety behaviors; (3) camps become more crowded and less compliant during the middle of the agricultural season; and (4) workers with H2A visas experience better conditions and practice more safety behaviors than do workers who do not have H2A visas. Further research needs to account for social and cultural factors. Regulations should be compared with pesticide metabolite levels to measure their effectiveness. More effort is needed to enforce existing regulations.

Abstract
Skin rashes are among the most common problems seen by those providing health care to agricultural workers. We present a case report of a migrant farmworker patient with a painful, blistering eruption of the axilla and adjacent skin developing after an insect bite. The possibility of infection was not initially considered, and teledermatology was helpful in making the diagnosis of bullous impetigo. This was important because initial culture confirmation was not obtained and antibiotic treatment had not been initiated. After the consultation, the impetigo was treated by empiric antibiotic coverage. The environmental conditions of migrant farmworkers raise special issues for infectious skin diseases like bullous impetigo. Crowded living conditions, lack of proper sanitary facilities, and poor accessibility to health care increase the risk of occurrence and spread of this disease. With the recent emergence of multi-drug-resistant organisms such as methicillin-resistant Staphylococcus aureus in community settings, this case report should serve to reinforce the need to recognize the possibility of infection and to obtain culture specimens at the initial visit to better treat and control this infectious skin condition.

Abstract
Past research on prostate and colorectal cancer disparities finds that barriers to screening, such as embarrassment and offensiveness, are often reported. Yet none of this literature investigates why. This study uses masculinity and health theory to examine how men experience two common screenings: digital rectal exams (DREs) and colonoscopies. In-depth interviews were conducted with 64 African American and White men from diverse backgrounds, aged 40 to 64, from North Carolina. Regardless of race or education, men experienced DREs more negatively than colonoscopies because penetration with a finger was associated with a gay sexual act. Some men disliked colonoscopies, however, because they associated any penetration as an affront to their masculinity. Because beliefs did not differ by race, future research should focus on structural issues to examine why disparities persist with prostate and colorectal cancer. Recommendations are provided for educational programs and physicians to improve men's experiences with exams that involve the rectum.

Abstract
This study tests basic predictions from the demands-control model of occupational stress in Latino immigrant farmworkers. Cross-sectional data were obtained from 151 farmworkers in eastern North Carolina via face-to-face interviews conducted in Spanish during the summer of 2005. Results suggest that farmwork is characterized by low psychological demand and low control, or that it is a "passive job." Multivariate analyses provided little support for predictions. Isometric load, an indicator of physical job demands reflecting how frequently workers maintain awkward postures for long periods, was associated with poorer physical health, and high worker control was associated with better mental health. However, pace of work, an indicator of psychological job demand, was unassociated with physical and mental health, and physical exertion, another indicator of physical job demand, was not robustly associated with health outcomes. The results suggest that core predictions from the demands-control model do not hold for immigrant farmworkers, and they foreshadow possible ways of refining the model.

Abstract
BACKGROUND Skin diseases are known to affect the quality of life (QoL), but data to support this are based on clinical samples. Few data document the skin-related QoL in the general population, and whether its association differs with self-reported or dermatologist-diagnosed skin ailments. Farmworkers are at high risk for skin diseases, and are an appropriate population in which to explore these associations. OBJECTIVES To compare the association between skin-related QoL and workers' self-reports of skin conditions or dermatologist-diagnosed skin diseases over the course of a work season. METHODS Three hundred and four Latino farmworkers were recruited from 45 randomly selected residential sites in North Carolina, USA, for longitudinal surveillance. The participants were interviewed up to five times at 3-week intervals and the reported skin problems and Dermatology Life Quality Index (DLQI) were recorded. Nine digital photographs were taken of each participant. A board-certified dermatologist rated each for the presence of specific skin diseases. RESULTS An impact of skin disease on QoL was reported in 16% of interviews. In multivariate analyses with self-reported skin problems, feet or skin fungus, rash, itching, and poison ivy were predictors of QoL. Dermatologist-diagnosed inflammatory diseases and pigmentary disorders were significant predictors of QoL. The association was stronger for self-reported skin problems than for dermatologist-diagnosed conditions. CONCLUSIONS In a population of farmworkers, skin problems had a clinically significant impact on QoL. Itch-related conditions and cosmetic conditions, such as acne and melasma, were important determinants of QoL. Treatment for these conditions in this population may enhance QoL.
