Mental health research with Latino farmworkers: a systematic evaluation of the short CES-D

Psychosocial Determinants of Mental Healthcare Use Among Mexican-origin Women from Farmworker Families in Southern California

Little is known about the contribution of psychosocial factors related to mental healthcare use among Mexican-origin women from farmworker families. Therefore, this study assessed relationships between acculturative stress, depressive symptoms, mental healthcare service use, and preferences for seeking care. Linear and logistic regression models and chi-square tests were performed to analyze survey data from 78 Mexican-origin women from farmworker families. Women were recruited in collaboration with promotoras and completed measures of acculturative stress, depressive symptoms, and mental healthcare use and preferences. Overall, 29.5% of the sample reported clinically significant depressive symptomatology. Acculturative stress was positively associated with depressive symptoms (b = 0.43, 95%CI = 0.27,0.59) after controlling for years in the U.S., primary language, and demographic characteristics. In addition, acculturative stress was associated with lower odds of mental healthcare use (OR = 0.96) after controlling for years in the U.S. and depressive symptoms. However, this association was no longer statistically significant when controlling for health insurance status and access to transportation. Mexican-origin women with high levels of acculturative stress were significantly more likely to seek care from a psychiatrist/psychologist than their peers (54.3% vs. 45.7%); however, this preference was not indicative of their use of mental healthcare services. Results suggest that acculturative stress is a risk factor for depressive symptoms and might contribute to a delay in seeking mental healthcare services in Mexican-origin women from farmworker families. Thus, interventions for this group should address aspects of acculturative stress as a strategy to increase mental health services use.

"We left the crop there lying in the field": Agricultural worker experiences with the COVID-19 pandemic in a rural US-Mexico border region

California agricultural workers are predominately Latino/a, are medically underserved, and reside in larger households, placing them at elevated COVID-19 risk at work and at home. While some research has examined COVID-19 among agricultural workers in the interior of the United States, little research exists on experiences of COVID-19 along the US-Mexico border. Grounded in resilience thinking, this study aims to understand how agricultural workers navigated their heightened risk to COVID-19 at work and at home, and made use of available resources in the context of a bi-national community. Our study utilized qualitative interviews with 12 agricultural workers to understanding the COVID-19 experiences of resident and daily migrant agricultural workers in Imperial County, California, located along the US-Mexico border. Findings suggest that agricultural workers faced significant impacts and risks at work (work stoppages, stress about bringing COVID-19 home to family) and at home (contracting COVID-19, loss of friends and family, and mental health challenges). Agricultural workers and their employers often implemented COVID-19 precautions such as social distancing measures, personal protective equipment, hand washing and hand sanitizers, and isolation. Many agricultural workers did access testing resources on either side of the US-Mexico border and worked with US-based Spanish-speaking community-based organizations to register for vaccine appointments. To better support agricultural workers and their employers in the future, we recommend the following: 1. Prioritize agricultural workplace conditions to increase agricultural worker physical and mental health, 2. Extend public health services into agricultural work sites of transit and the workplace, and 3. Lastly, trusted Spanish-speaking community-based organizations can play a critical role in public health outreach.

Occupational Stressors and Access to COVID-19 Resources among Commuting and Residential Hispanic/Latino Farmworkers in a US-Mexico Border Region

Hispanic/Latino and migrant workers experience high degrees of occupational stress, constitute most of California’s agricultural workforce, and were among the most impacted populations by the COVID-19 pandemic. However, relatively little is known about the occupational stress experienced by farmworkers who commute daily between the US and Mexico. Occupational stress is considered an imbalance between the demands at work and the capabilities to respond in the context of the workforce. The goal of this study is to determine the type and severity of stressors in daytime and resident farmworkers and how COVID-19 vaccination status contributes to these stressors. Interviews containing the Migrant Farmworker Stress Inventory (MSWSI) were administered to a sample of 199 Hispanic/Latino farmworkers in Imperial County, a multi-billion-dollar agriculture sector in the US. Principal factor analysis differentiated latent factors in the MFSWI. Simple linear regression models and correlations identified associations between MFWSI scores and sample characteristics. The MFWSI reduced to five stressor domains: Health and Well-Being Vulnerabilities, Inadequate Standards of Living/Unknown Conditions of Living, Working Conditions, Working Environment, and Language Barriers. Approximately 40 percent of the respondents reported significant stress levels, with foreign-born (p = 0.014) and older respondents (p = 0.0415) being more likely to experience elevated stress regardless of their nighttime residence. We found that Spanish-language COVID-19 outreach might have been particularly effective for workers who reported high stress from English-language communication (p = 0.001). Moreover, our findings point to the importance of worker and human rights to mitigate the high-stress foreign-born workers who live in Mexico and the US experience.

Racial Discrimination and Depressive Symptoms among Latina/o College Students: The Role of Racism-Related Vigilance and Sleep

INTRODUCTION

Latinx college students are at high risk of suffering from depressive symptoms. A factor posited to influence depressive symptoms among Latinx college students is racial/ethnic discrimination. However, the mechanisms which link racial/ethnic discrimination to depressive symptoms are not well understood. This study examined the mediating role of racism-related vigilance and sleep-related factors (i.e., sleep quality, sleep efficiency) on the relationship between perceived intergroup racial/ethnic discrimination and depressive symptoms.

METHODS

Participants were 194 Latinx college students enrolled at a Midwestern university designated as a Hispanic-Serving Institution. Path analysis was conducted to investigate whether racism-related vigilance and sleep-related factors (i.e. sleep quality, sleep efficiency) are potential pathways in the relationship between intergroup racial/ethnic discrimination and depressive symptoms.

RESULTS

Path analysis revealed that racism-related vigilance and sleep quality sequentially mediated the effect of perceived intergroup racial/ethnic discrimination on depressive symptoms. Sleep efficiency did not mediate the relationship between racial/ethnic discrimination and depressive symptoms.

DISCUSSION

This study is among the first to document that intergroup racial/ethnic discrimination is negatively related to mental health through both cognitive and behavioral mechanisms. This research has important implications for understanding how discrimination may influence mental health outcomes among Latinx college students.

Examination of Symptoms of Depression among Cooperative Dairy Farmers

Farmers experience a high risk of stress, depression, and suicide. Risk factors are well documented but protective factors are seldom examined. Social support has been reported to reduce psychological distress among the general population but its effect on farmers is inconclusive. Agricultural cooperatives are typically created and owned by farmers to secure markets, access supplies and services, and participate in decision-making. It is unknown whether having cooperative resources impacts symptoms of depression. A survey was used to examine whether having access to cooperative programs and social support impacted symptoms of depression among dairy farmers. Farm bankruptcies, stress, depression, and suicide were identified as ongoing concerns. Having social support and cooperative educational opportunities and mentorship programs were associated with decreased symptoms of depression. Conversely, having cooperative policy discussions was associated with increased symptoms of depression. Results suggest that social support can potentially reduce symptoms of depression among farmers and having access to cooperative resources can reduce or increase it, depending on the type of program. Our findings identified an opportunity to further examine how programs provided by farmer-led organizations such as cooperatives can impact stress, depression, and suicide among farmers.

A Systematic Review and Meta-Analysis of Depression among Farming Populations Worldwide

A systematic review and meta-analysis were conducted to determine the overall prevalence of depression among farming populations globally, and explore any heterogeneity present. Eligible studies were primary research articles published in English, which involved the collection of data for the purpose of determining the prevalence of depression among a farming population. Four relevant databases were searched in January 2019. Potential for bias was assessed using a modified Quality Assessment of Diagnostic Accuracy Studies (QUADAS) tool. From 7662 records, 72 articles were deemed relevant and had data extracted. Of these, 45 utilized the Center for Epidemiologic Studies—Depression Revised scale (CES-D/DR) to quantify depression, 42 of which were conducted in the United States (U.S.). As a result, meta-analyses were restricted to this geographic location. Substantial heterogeneity was seen in the initial whole-group analysis (I² = 97%), and while sub-group exploration suggested a significantly higher prevalence of depression among migrant farm workers (26%, 95% CI = 21–31%) than in studies examining a non-migrant farming population (12%, 95% CI = 8–17%), substantial heterogeneity remained (I² = 96%), indicating that the majority of between study variation was due to factors other than sampling error. Additionally, the majority of studies (81%) in migrant farm worker populations were published since 2010, while only 21% of studies in non-migrant farming populations were published in this timeframe. It is possible with recent efforts to de-stigmatize mental illness, participants in more recent studies may be more likely to self-report depressive symptoms. Hence, while it appears that migrant farmworker populations may have an elevated prevalence of depression, it is also apparent that little research in the U.S. has been done to evaluate depression among non-migrant farming populations in recent years. Perhaps a reporting bias may account for some of the difference between the two populations. A research gap also appears to exist in estimating the prevalence of depression among farming populations outside of the US. Assessment for bias at the study level revealed challenges in reporting of key study design elements, as well as potential for selection bias in the majority of studies.

Association between depressed mood and sexual function among mid-aged Paraguayan women

BACKGROUND

Depressive symptoms may affect female mid-life sexuality, whereas sexual problems tend to aggravate depression. Despite this, data assessing this association drawn from mid-aged Paraguayan women are scarce.

OBJECTIVE

This study aimed to assess the association between depressed mood and the risk of sexual dysfunction during female mid-life.

METHODS

Sexually active urban-living women from Asunción, Paraguay (n = 193, aged 40-60 years) were surveyed with the 6-item Female Sexual Function Index (FSFI-6), the 10-item Center for Epidemiological Studies Depression Scale (CESD-10), and a general questionnaire containing personal and partner information. Depressed mood was defined as a total CESD-10 score of 10 or more, and an increased risk for sexual dysfunction as an FSFI-6 total score of 19 or less. The association of depressed mood and an increased risk of sexual dysfunction was evaluated with multivariable Poisson regression.

RESULTS

The mean age (±standard deviation) of surveyed woman was 48.3 ± 6.0 years and 61.1% (n = 118) were perimenopausal and postmenopausal. A total of 21.8% (n = 42) had depressed mood and 28.5% (n = 55) had an increased risk of sexual dysfunction. The final adjusted regression model determined that women with depressed mood were twice as likely to have an increased risk of sexual dysfunction, compared to women with normal mood (adjusted prevalence ratio = 2.14, 95% confidence interval 1.26-3.60). On the other hand, depressed mood was associated with a mean total FSFI-6 score that was 20% lower than that observed among women with normal mood (adjusted incidence rate ratio = 0.80, 95% confidence interval 0.68-0.93).

CONCLUSION

In this mid-aged Paraguayan female sample there was a significant association between depressed mood and an increased risk of sexual dysfunction.

Social support, rural/urban residence, and depressive symptoms among Chinese adults

This study aims to examine the extent to which people are socially integrated and the association between social support and depressive symptoms among Chinese adults, with regard to the moderating effect of the rural or urban residence. The author used data from the China health and longitudinal study (CHARLS), a nationally representative longitudinal survey of the population of adults aged over 45 in China. A total of 16,372 participants were included in this study, and the mean age of the sample was 59.7. Three variables were used to measure participants' social support: family size, proximity of support, and social involvement. The Chinese version of 10-item center for epidemiologic studies depression scale was used as a measurement tool for depressive symptoms. The findings demonstrate that small family size, living with a spouse, frequency of contact with children, and a number of social activities have significant effects on depressive symptoms. For all aspects of social support, the influence on depressive symptoms is not significantly different between urban and rural areas. Family support, especially the support of a spouse is crucial to prevent depression. This study also identifies the vital effect of social activity and encourages the government to improve public services, especially in rural areas.

Crime Victimization and Suicidal Ideation Among Colombian College Students: The Role of Depressive Symptoms, Familism, and Social Support

Crime victimization is one of the most pressing public health concerns in Latin America. Young people in the region are at particularly high risk of victimization. The present study examined exposure to crime victimization as a risk factor for depressive symptoms and suicidal ideation, and the protective effects of familism and social support in a community sample of Colombian college students. Data (N = 424) came from the Juventud Project (The Emergent Adults Project), a cross-sectional study of college students, 18 to 29 years old (M = 20.8, SD = 2.5; 63% female; 75.5% lived with their families), attending an urban public university in Southern Colombia. Data were collected between March and June of 2014 through anonymous, self-administered surveys. Conditional process analysis was used to test a model in which crime victimization was directly and indirectly associated with suicidal ideation via depressive symptoms, with familism and social support as moderators of this association while controlling for gender, age, and socioeconomic status. Overall, 58.9% of participants reported at least one crime victimization event in the past year. The most common types of victimization were being robbed without the threat of harm (29.8%) and being robbed with a weapon (24.8%). Male participants reported more instances of crime victimization than female participants. Levels of depressive symptoms that could be clinically significant were reported by 30.2% of participants, and suicidal ideation was reported by 31% of participants. The association between crime victimization and suicidal ideation was fully mediated by depressive symptoms. Social support, but not familism, moderated this association; social support weakened the link between depressive symptoms and suicidal ideation. Findings suggest that crime victimization may be a significant risk for depressive symptoms and suicidal ideation among college students in Colombia, and that social support may protect from the harmful mental health effects of crime victimization.

Improving Detection of Depression Symptoms in Latino Farmworkers: Latino Farmworker Affective Scale

Latino farmworkers (LFWs) experience depression at a significant higher rate than non-Latino Whites; yet, research regarding depression-screening instruments in Spanish is scarce. The first author created a depression screener using terms used by LFWs to describe symptoms of depression. This study evaluated the effectiveness of the Latino Farmworker Affective Scale (LFAS-15) in accurately detecting symptoms of depression in this population as compared with the Patient Health Questionnaire (PHQ-9), the Brief Symptom Inventory (BSI-18), and the Center for Epidemiologic Studies Depression Scale (CESD-10) using the DSM structured clinical interview (SCID) as the reference standard. Study results indicated that the LFAS-15, as well as the PHQ-9, and the BSI-18 performed. The data also indicated that the LFAS-15 has good internal consistency, measures primarily one construct (depression), demonstrated convergent validity with the SCID, and has good combined sensitivity and specificity. Recommendations for clinical practice, policy, and research are offered.

Central American Immigrant Mothers' Mental Health in the Context of Illegality: Structural Stress, Parental Concern, and Trauma

Using a community-based participatory research approach, we surveyed 134 undocumented Central American immigrant mothers to examine correlates of maternal mental health. Drawing upon an ecosystemic framework, predictors of depression included structural and familial stressors, parental concerns, and maternal health factors. Mothers' perceptions of child affect, traumatic stress, and general health ratings were among the most salient predictors. However, structural and familial stressors, such as food insecurity and single parenting, also accounted for significant variance in depression scores. Findings informed community actions such as advocating for mental health care and building awareness of families' lived experiences within the local school system.

Migration and depression: A cross-national comparison of Mexicans in sending communities and Durham, NC

RATIONALE

Latino immigrants have been shown to average better health and longevity than native whites, in spite of their relative socioeconomic disadvantage. However, mental health outcomes stand in stark contrast to this epidemiological "paradox," as factors such as depression are significantly higher for Latino immigrants than other groups.

OBJECTIVE

We explore the link between migration and depressive feelings using a binational random survey of Mexicans in Durham, NC and sending communities in Mexico.

METHOD

Explanations for the link between migration and depression, such as acculturative stress, lack of social support, and powerlessness and isolation, are analyzed by comparing results for protective vs. risk factors between residents of Mexico and Durham, and among immigrants themselves. Besides, selection hypothesis is explored using propensity matching scores.

RESULTS

Results show little support for selection as an important source of migrant depression, and instead provide strong evidence that migration itself, and the disruption of social networks that it entails, is primarily responsible for the association. Family separation, in particular, is the strongest predictor of depressive feelings and accounts for a sizeable portion of the heightened depression among migrants.

CONCLUSIONS

Understanding the subjective experiences of migration is necessary to better integrate newcomers into host societies.

The Impact of Work Demand and Gender on Occupational and Psychosocial Stress in Hispanic Farmworkers

Hispanic farmworkers experience hazardous work conditions, language barriers, poverty, and limited healthcare access that increase their risk for health problems. We sought to characterize occupational and lifestyle stressors in farmworker couples and to examine the impact of seasonal work demand and gender on health outcomes. We administered surveys to 31 couples (N = 62) in May (low work demand) and September (high work demand) of 2012. Measures included acculturation, perceived stress, depressive symptoms, quality of life, decision latitude, support (supervisor, co-worker), and work-family conflict. This population did not report significant differences in stress in low and high work demand times. Women reported more work-family conflict (F = 19.06, p 0.0001; F = 11.28, p = 0.0015) and less supervisor support (F = 6.56, p = 0.0135). Women experienced more conflict between work and family and less support at work. This group reported low depressive symptomology and moderate levels of stress; a subset reported elevated levels.

Mental Health Among Latina Farmworkers and Other Employed Latinas in North Carolina

The mental health of Latinas with manual occupations, particularly those employed in agriculture, is a public health concern. The goals of this analysis were to describe the mental health of Latina farmworkers, and to compare their mental health with that of other Latina manual workers. Participants included 35 employed Latina farmworkers, 35 employed non-farmworkers, and 25 unemployed non-farmworkers who completed interviews in 2012. Measures included stress, anxiety, depressive symptoms, elevated depressive symptoms, and risk for alcohol dependence. Farmworkers had greater stress and anxiety than did employed and unemployed non-farmworkers. Employed Latinas, whether farmworkers or in other occupations, had greater stress and anxiety than unemployed Latinas. Depressive symptoms, although high, did not differ significantly by occupation and employment. Few were at risk for alcohol dependence. Concrete steps are needed to address the mental health of Latina farmworkers, and to continue documentation of mental health concerns and their causes in this population.

Elevated Depressive Symptoms Among Hired Crop Workers in the United States: Variation by Sociodemographic and Employment Characteristics

We present prevalence rates, along with demographic and economic characteristics associated with elevated depressive symptoms (EDS), in a nationally representative sample of hired crop workers in the United States. We analyzed in-person interviews with 3,691 crop workers collected in 2009-2010 as part of a mental health and psychosocial supplement to the National Agricultural Workers Survey. The prevalence of EDS was 8.3% in men and 17.1% in women. For men, multivariate analysis showed that EDS was associated with years of education, family composition, having a great deal of difficulty being separated from family, having fair or poor general health, ability to read English, fear of being fired from their current farm job, and method of payment (piece, salary, or a combination). Interactions were found between region of the country and family composition. Multivariate analyses for women showed that fear of being fired, fair or poor general health, having children ≤15 years of age, being unaccompanied by their nuclear family, expectation for length of time continuing to do farm work in the United States, and authorization status were associated with EDS. Interactions were found with Hispanic ethnicity and region of the country, as well as presence of the nuclear family and region. The present study identifies important risk factors in this first population-based assessment of EDS in a nationally representative sample of U.S. crop workers. The importance of social support from family, job insecurity, and high prevalence of EDS in female crop workers support the need for screening and outreach in this primarily rural group of men and women crop workers.

Deportation and mental health among migrants who inject drugs along the US-Mexico border

This study describes the prevalence and factors of depressive symptoms among a sample of persons who inject drugs (PWID) with a history of deportation from the US in Tijuana, Mexico. In 2014, 132 deported PWID completed a structured questionnaire. Depressive symptoms were measured using the Center for Epidemiologic Studies Short Depression Scale (CESD-10) screening instrument. Eligible participants were ≥18 years old, injected drugs in the past month, spoke English or Spanish, and resided in Tijuana. Multivariate analyses identified factors associated with depressive symptoms. Among deported PWID, 45% reported current symptoms of depression. Deported PWID who were initially detained in the US for a crime-related reason before being deported (adjusted odds ratio (AOR): 5.27; 95% CI: 1.79-15.52) and who perceived needing help with their drug use (AOR: 2.15; 95% 1.01-4.61) had higher odds of reporting depressive symptoms. Our findings highlight the need for effective strategies targeting deported migrants who inject drugs to treat mental health and drug abuse in Tijuana. Investing in the mental health of deported PWID may also be a viable HIV prevention strategy.

Childhood Injury Prevention: Predictors of Home Hazards in Latino Families Enrolled in SafeCare®

Objective

This archival project (a) examined potential risk and protective factors for hazards in the homes of Spanish-speaking immigrant Latino families and (b) provided an independent examination of the SafeCare®+ Home Safety module adapted for Latino families at high risk for child neglect.

Methods

The sample comprised 92 Latina caregivers of young children enrolled in SafeCare®+.

Results

Results of the negative binomial regression model of predictors of home hazards before the Home Safety module found none of the factors were significant. The longitudinal analysis with a negative binomial model found significant effects both during (b = -0.905, p < .001) and after (b = -2.118, p < .001) the intervention. Depression was negatively associated with the number of hazards (b = -0.026, p < .05, β = -.1858).

Conclusions

Support for application of SafeCare®+ Home Safety module to prevent access to hazards for Latino children was found.

Comparison of the Center for Epidemiology Studies Depression Scale and Beck Depression Inventory for Research with Latinas

U.S. Latino farmworkers face multiple potential stressors. Research on the mental health status of this U.S. Latino subgroup has suggested high prevalence of stress, anxiety, and depressive symptoms when compared to other groups. Latina farmworkers may be at greater risk than their male counterparts for poor mental health because they confront many of the same stressors but may experience additional difficulties including domestic violence, taking on new roles and responsibilities on top of traditional ones, and being expected to maintain the health and integrity of their families at the expense of their own needs. Most of the research on Latino/Latina farmworker mental health has focused on identifying prevalence of mental health symptoms and the vulnerabilities that predict these symptoms. A variety of instruments with English and Spanish versions have been employed to measure depressive symptoms in U.S. Latinos. Two such instruments, the Center for Epidemiology Studies Depression Scale and the Beck Depression Inventory, are evaluated in this article to determine which is more valid, reliable, relevant, and useful for a proposed study on stress, social support, coping, and depression in U.S. Latina farmworkers and which is more congruent with the study's conceptual framework, Lazarus and Folkman's transactional model of stress, appraisal, and coping. Though each instrument is shown to have certain advantages over the other, neither is definitively judged to be more appropriate for this largely unexplored subgroup. What is proposed instead is to conduct a mixed methods study to further evaluate the potential applicability of each instrument.

Associations of Poor Housing with Mental Health Among North Carolina Latino Migrant Farmworkers

This analysis examines the associations of housing conditions with mental health among migrant farmworkers. Data are from a 2010 cross-sectional study conducted in 16 North Carolina counties. Interviews and housing inspections were completed with 371 farmworkers in 186 camps. Mental health measures included depression (Center for Epidemiologic Studies Depression Scale, CES-D), anxiety (Personality Assessment Inventory, PAI), and alcohol misuse (Alcohol Use Disorders Identification Test, AUDIT-C). Housing measures were number of people per sleeping room, perceived security of self and belongings, having a key to dwelling's door, having bedroom storage, toilet privacy issues, and number of housing regulation violations. Sixty (16.7%) participants had substantial depressive symptoms (CES-D ≥10), 31 (8.8%) had substantial anxiety (PAI ≥27), and 185 (50.1%) had the potential for alcohol misuse (AUDIT-C ≥4). Those with 5+ persons sleeping per room were more likely to have a depression score ≥10 (31.5% vs. 13-14%, P = .01) and an anxiety scores ≥27 (19.6% vs. 5-9%, P = .02). Those who did not feel they or their belongings were secure were more likely to have a depression score ≥10 (19.4% vs. 9.1%, P = .01). Those without a key were more likely to have an anxiety score ≥27 (11.5% vs. 5.1%, P = .04). Those with no bedroom storage were more likely to have a depression score ≥10 (28.9% vs. 14.9%, P = .03). This article suggests links between poor housing and farmworkers' mental health. These results inform regulations surrounding farmworker housing and inform health care providers on how to prevent and treat poor mental health among migrant farmworkers.

Reliability, validity and factor structure of the CES-D in Iranian elderly

OBJECTIVES

In developing countries such as Iran, elder populations are growing. Due to the high prevalence of depressive disorders among elders, reliable screening instruments for this population are required. The main purpose of this study was to determine the reliability and validity of the Farsi version of the Center for Epidemiological Studies-Depression Scale-10 (CES-D) among Iranian elderly persons.

METHODS

The investigators created the Farsi version of the CES-D-10 by translation and back translation. Two hundred and four cases aged 59 and above completed the questionnaire. The reliability and validity of the translated CES-D-10 was established through comparison with the Composite International Diagnostic Interview (CIDI), a recognized gold standard method for diagnosing major depressive disorder. We used a receiver operating curve (ROC) to determine the optimum cutoff score.

RESULTS

The Farsi version of the CED-D-10 displayed acceptable psychometric characteristics, as reflected in internal consistency with Cronbach's alpha, split-half coefficients and test-retest reliability of 0.85, 0.65 and 0.49, respectively. Factor analysis and the varimax rotation resulted in two factors including 'depression' and 'interpersonal relationships'. The Depression factor (introduced as CES-D-8 of the scale) had significant correlation with the 10 items form (r=0.99) with 0.87 alpha coefficient. The ROC showed that the optimum cutoff point is 5 with sensitivity of 82% and specificity of 70%, and positive and negative predictive values of 26% and 98%, respectively, for both of the forms.

CONCLUSION

Both the 10 and 8 items form of the Farsi version have desirable characteristics to be useful as a screening instrument for depressive disorders in Iranian elders, especially in urban areas.

Collecting Comparative Data on Farmworker Housing and Health: Recommendations for Collecting Housing and Health Data Across Places and Time

The substandard nature of the housing in which most farmworkers live has detrimental effects on their health, as well as on their children's health and development. However, little research has directly documented associations between farmworker housing and health; existing research is not always comparable due to differences in design and measurement. Comparative data can help determine actual causal links between housing characteristics and farmworker health and help to evaluate the efficacy of current housing policy. The goal of this paper is to provide guidelines promoting comparable research on farmworker housing and the association of this housing with health. This paper reviews general concepts relevant to measuring farmworker housing and health, issues that should be considered in designing farmworker housing and health research, data collection methods, and measures. It concludes with recommendations for a research agenda on farmworker housing and health.

Interpersonal and social correlates of depressive symptoms among Latinas in farmworker families living in North Carolina

Little research is available about the mental health of Latina women in farmworker families living in the southern United States, where Latino immigrants are relatively recent arrivals. This study examined interpersonal correlates (family conflict, family's outward orientation, and perceived discrimination) and social correlates (residential mobility and economic insecurity) of depressive symptoms and of meeting a threshold of depressive symptoms that could be clinically significant (a cut-point of 10 or higher in a short Center for Epidemiologic Studies-Depression Scale) among Latinas in farmworker families living in North Carolina. Data were collected from April 19, 2011 to April 20, 2012 as part of Niños Sanos, a prospective study of Latino women and children (N = 248). Regression models showed that exposure to family conflict, perceived discrimination, and economic insecurity were associated with more depressive symptoms. Likewise, perceived discrimination and economic insecurity were associated with a threshold of depressive symptoms that could be clinically significant, above and beyond family conflict. The findings suggested that policies that lessen the discrimination of farmworkers and their families and reduce economic insecurity, as well as interventions that support positive family functioning, might be beneficial for the mental health of Latinas in farmworker families living in new immigrant destinations.

Job control, psychological demand, and farmworker health: evidence from the national agricultural workers survey

OBJECTIVE

Improve understanding of the potential occupational health impact of how agricultural jobs are organized. Exposure to low job control, high psychological demands, and high job strain were hypothesized to have greater risk for poor self-rated physical health and elevated depressive symptoms.

METHODS

Cross-sectional data (N = 3691) obtained using the Work Organization and Psychosocial Factors module of the US National Agricultural Workers Survey fielded in 2009-2010.

RESULTS

More than one fifth (22.4%) of farmworkers reported fair/poor health, and 8.7% reported elevated depressive symptoms. High psychological demand was associated with increased risk of fair/poor health (odds ratio, 1.73; 95% confidence interval, 1.4 to 2.2) and elevated depressive symptoms (odds ratio, 2.6; 95% confidence interval, 1.9 to 3.8).

CONCLUSIONS

The organization of work in field agriculture may pose risks for poor occupational health outcomes among a vulnerable worker population.

Evaluating Job Demands and Control Measures for Use in Farm Worker Health Surveillance

Workplace stress likely plays a role in health disparities; however, applying standard measures to studies of immigrants requires thoughtful consideration. The goal of this study was to determine the appropriateness of two measures of occupational stressors ('decision latitude' and 'job demands') for use with mostly immigrant Latino farm workers. Cross-sectional data from a pilot module containing a four-item measure of decision latitude and a two-item measure of job demands were obtained from a subsample (N = 409) of farm workers participating in the National Agricultural Workers Survey. Responses to items for both constructs were clustered toward the low end of the structured response-set. Percentages of responses of 'very often' and 'always' for each of the items were examined by educational attainment, birth country, dominant language spoken, task, and crop. Cronbach's α, when stratified by subgroups of workers, for the decision latitude items were (0.65-0.90), but were less robust for the job demands items (0.25-0.72). The four-item decision latitude scale can be applied to occupational stress research with immigrant farm workers, and potentially other immigrant Latino worker groups. The short job demands scale requires further investigation and evaluation before suggesting widespread use.

Hypertension management using mobile technology and home blood pressure monitoring: results of a randomized trial in two low/middle-income countries

OBJECTIVE

Hypertension and other noncommunicable diseases represent a growing threat to low/middle-income countries (LMICs). Mobile health technologies may improve noncommunicable disease outcomes, but LMICs lack resources to provide these services. We evaluated the efficacy of a cloud computing model using automated self-management calls plus home blood pressure (BP) monitoring as a strategy for improving systolic BPs (SBPs) and other outcomes of hypertensive patients in two LMICs.

SUBJECTS AND METHODS

This was a randomized trial with a 6-week follow-up. Participants with high SBPs (≥140 mm Hg if nondiabetic and ≥130 mm Hg if diabetic) were enrolled from clinics in Honduras and Mexico. Intervention patients received weekly automated monitoring and behavior change telephone calls sent from a server in the United States, plus a home BP monitor. At baseline, control patients received BP results, hypertension information, and usual healthcare. The primary outcome, SBP, was examined for all patients in addition to a preplanned subgroup with low literacy or high hypertension information needs. Secondary outcomes included perceived health status and medication-related problems.

RESULTS

Of the 200 patients recruited, 181 (90%) completed follow-up, and 117 of 181 had low literacy or high hypertension information needs. The median annual income was $2,900 USD, and average educational attainment was 6.5 years. At follow-up intervention patients' SBPs decreased 4.2 mm Hg relative to controls (95% confidence interval -9.1, 0.7; p=0.09). In the subgroup with high information needs, intervention patients' average SBPs decreased 8.8 mm Hg (-14.2, -3.4, p=0.002). Compared with controls, intervention patients at follow-up reported fewer depressive symptoms (p=0.004), fewer medication problems (p<0.0001), better general health (p<0.0001), and greater satisfaction with care (p≤0.004).

CONCLUSIONS

Automated telephone care management plus home BP monitors can improve outcomes for hypertensive patients in LMICs. A cloud computing model within regional telecommunication centers could make these services available in areas with limited infrastructure for patient-focused informatics support.

Depressive symptoms and sleepiness among Latino farmworkers in eastern North Carolina

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

Multiple instrument translation for use with South Asian Indian immigrants

The purpose of this study was to describe translation of five measures (physical activity, acculturation, discrimination, self-efficacy, and depression) from English into Hindi using the committee translation method, focus group, and think-aloud interviews. Two South Asian Indian (SAI) immigrant bilingual translators and a moderator reached consensus on 93 of 102 items, using the committee method. Discrepancy in nine items was resolved with a focus group conducted with five bilingual SAI immigrants. Ten other bilingual SAI immigrants participated in think-aloud interviews to assess understanding and interpretation of the questions. More than 10 additional changes were made following the think-aloud interviews. Sequential use of multiple translation techniques improved translation with culturally acceptable language, thereby maintaining equivalence with original versions.
