Abstract
Keywords
Latinos are the largest ethnic minority group in the United States and now comprise 18% of the population (U.S. Census Bureau, 2016). Previous studies have identified that patterns of mental health among Latinos vary depending on country of origin and immigrant generation (Alegría et al., 2007; Oquendo, Lizardi, Greenwald, Weissman, & Mann, 2004; Wassertheil-Smoller et al., 2014). While Latino immigrants often have better mental health than U.S.-born Latinos, some studies have reported that depression among immigrants increases with time spent in the United States (Grant, Stinson, Hasin, et al., 2004; Ortega, Rosenheck, Alegría, & Desai, 2000; Vega, Sribney, Aguilar-Gaxiola, & Kolody, 2004; Wassertheil-Smoller et al., 2014). A recent national study reported a depression prevalence of 27% among Latinos, while it is estimated at 8% for the general U.S. population (Pratt & Brody, 2014; Wassertheil-Smoller et al., 2014). The prevalence of anxiety among U.S. Latinos is much lower at 2%, close to levels in the general population, where prevalence estimates range from 1% to 4% (Grant, Stinson, Dawson, et al., 2004; Martin, 2003; Priest & Denton, 2012; U. S. Department of Health and Human Services, National Institutes of Health & National Institute of Mental Health, n.d.).
The Minority Stress model theorizes that Latino immigrants may be at increased risk for poor mental health due to stressors associated with their multiple minority statuses (Meyer, 2003). For example, Latino immigrants may experience stressors related to migration and legal status, racial/ethnic discrimination, and lower socioeconomic status, all of which have been associated with depression and anxiety (Finch, Kolody, & Vega, 2000; Potochnick & Perreira, 2010; Ramos, Su, Lander, & Rivera, 2015). In addition to their impact on mental health, minority status stressors can also lead to increased use of alcohol, tobacco, and other drugs as a coping strategy (Keyes, Hatzenbuehler, Grant, & Hasin, 2012). Substance use is often associated with poor mental health, and comorbidity between substance use disorders and mood disorders is especially common (Degenhardt & Hall, 2001; Grant, Stinson, Dawson, et al., 2004; Regier et al., 1990). The theory also stipulates that, when available, social support can buffer the impact of stressors on health behaviors. However, Latino immigrant men may have limited access to social support due to social isolation, language barriers, discrimination, and norms of masculinity (Duke, Bourdeau, & Hovey, 2010; Nelson, Schmotzer, Burgel, Crothers, & White, 2012; Steel, Fernandez-Esquer, Atkinson, & Taylor, 2017).
Latino immigrant men who seek employment as day laborers after arriving in the United States may be at particularly high risk for poor mental health. Latino day laborers are often undocumented immigrants who seek employment in the informal labor market doing construction or landscaping (Valenzuela, 2003). Day laborers are often paid low wages, are prone to wage theft, and experience difficult and dangerous working conditions (Díaz Fuentes, Martinez Pantoja, Tarver, Geschwind, & Lara, 2016; Fernández-Esquer, Fernández-Espada, Atkinson, & Montano, 2015; Negi, 2011, 2013). Day laborers are also vulnerable to exploitation, discrimination, and abuse by employers and law enforcement, especially if they are undocumented immigrants (Hall & Greenman, 2015; Negi, 2011, 2013; Quesada et al., 2014). In addition to these economic and occupational stressors, day laborers commonly experience unstable living conditions, including homelessness and crowding in shared housing (Organista, Ngo, Neilands, & Kral, 2017).
Only a few studies have specifically assessed patterns and correlates of mental health outcomes among Latino day laborers. A mixed-method study of Latino day laborers in the Southwest reported that 39% experienced psychological distress (Negi, 2013). In a Los Angeles area study, Latino day laborers reported experiencing mild to moderate levels of depressive symptoms on average (Bacio, Moore, Karno, & Ray, 2014). A study in the San Francisco area reported that Latino day laborers with difficult living conditions had higher levels of depression and
This study aims to build on this literature by identifying which specific stressors and forms of substance use are associated with poor mental health in a recruited sample of Latino day laborers in King County, Washington.
Methods
Participants and Data Collection
Data for this study were collected as part of Vida PURA, a community-based study on alcohol use patterns of Latino day laborers (Ornelas et al., 2016). Participants were recruited in 2013 at a day labor worker center in King County, Washington, and considered eligible if they were Spanish-speaking, foreign-born, adult (18+) men who identified as Latino. Informed consent was obtained from all individual participants included in the study. Once eligible men provided consent, they completed an interviewer-administered survey in a private location at the worker center. Surveys were conducted in Spanish by bilingual, Latino research staff and included measures of mental health, demographic characteristics, social stressors and supports, and substance use. Participants received a $25 incentive after completing the survey. All human subjects research procedures were approved by and conducted in accordance with the University of Washington Human Subjects Division. Staff from local health and social service agencies also served as community advisors for the study.
Mental health
Depression was measured using the Patient Health Questionnaire (PHQ-9), a nine-item screening questionnaire with scores ranging from 0 to 27 that has been validated as a tool for depression screening in both clinical and community settings (Löwe, Unützer, Callahan, Perkins, & Kroenke, 2004; Martin, Rief, Klaiberg, & Braehler, 2006). Its consistency was high in this community-based sample (α = 0.83). In addition to total scores, established criteria were used to classify mild (≤5), moderate (≤10), moderately severe (≤15), and severe depression (≤20; Kroenke, Spitzer, & Williams, 2001). A score of 10 or higher was used to identify individuals with moderate to severe depression, which has high sensitivity (0.85) and specificity (0.89) for use in identifying major depressive disorder (Manea, Gilbody, & McMillan, 2012). The PHQ-9 has been validated in Latino populations and in Spanish (Huang, Chung, Kroenke, Delucchi, & Spitzer, 2006).
Anxiety was measured using the Generalized Anxiety Disorder scale (GAD-7), a seven-item screening questionnaire with scores ranging from 0 to 21. The GAD-7 had high internal consistency in this sample (α = 0.87). Established criteria were used to classify mild (≤5), moderate (≤10), and severe anxiety (≤15; Spitzer, Kroenke, Williams, & Löwe, 2006). A score of 10 or higher was used to indicate moderate or worse anxiety, which has been used in previous studies because of its high sensitivity (0.89) and specificity (0.82) when compared to other diagnostic measures (Spitzer et al., 2006). The GAD-7 has been validated with Spanish-speaking U.S. Latinos (S. D. Mills et al., 2014).
Social stressors
The measure of discrimination used in this study was based on items used in the California Health Interview Survey, and included separate questions about experiencing discrimination in different settings (Ornelas, Mariscal, & Thompson, 2011; Shariff-Marco et al., 2009). Participants were asked whether, since arriving in the United States, they had been “treated unfairly or been discriminated against” at work, when getting medical care, by the police and courts, or in other situations (other situations identified by participants included public transportation, on the streets, and at school). Indicator variables were created for each setting, as well as for having experienced discrimination in “any” setting (one of the settings listed above or any other setting not explicitly asked about in the survey).
Acculturation stress was measured using nine items from the Migrant Farmworker Stress Inventory (MFWSI), which measures types of stressors as well as the level of stress experienced (Hovey, 2000). Items were selected based on previous research on social stressors among day laborers and community advisors’ input on the most relevant stressors for day laborers (Negi, 2011; Negi et al., 2015; Organista, Ngo, et al., 2017; Ornelas, Allen, Vaughan, Williams, & Negi, 2015). The selected items included: difficulty communicating in English, not being able to make desired purchases, difficulty accessing health care, working long hours, difficulty being away from friends and family, being taken advantage of by an employer or landlord, feeling like they do not belong in the United States, difficulty finding housing, and difficulty finding a job. Each item was scored on a 4-point scale, indicating how stressful participants found each situation. Response options included
Social support was measured with five items from the Index of Sojourner Social Support (ISSS) scale (α = 0.75). The ISSS was developed specifically to examine elements of social support that are relevant for immigrants (Ong & Ward, 2005; Rhodes et al., 2013). The five items asked participants whether they had people in their lives who would offer them emotional support (e.g., “Do you have persons in Seattle who would listen and talk with you when you feel lonely or depressed?”) and practical help (e.g., “Do you have persons in Seattle who would tell you what can and cannot be done in the United States?”). Response options were measured with a 5-point scale:
Substance use
The Alcohol Use Disorders Identification Test (AUDIT) screening questionnaire was used to assess unhealthy alcohol use. The AUDIT includes items related to consumption and frequency of alcohol use as well alcohol-related problems with scores ranging from 0–40. The measure had high internal consistency in this sample (α = 0.88) and has been validated for use in Spanish-speaking populations (Bacio et al., 2014; Gómez, Conde, Santana, & Jorrín, 2005; Ornelas et al., 2016). An indicator for unhealthy alcohol use was created for participants who scored 8 or higher, a commonly used cut-off score for higher risk drinking (Rubinsky, Dawson, Williams, Kivlahan, & Bradley, 2013).
Frequency of tobacco use (not at all, some days, or every day) was measured using items selected from the National Adult Tobacco Survey, and participants were categorized as current smokers if they smoked cigarettes at least some days (Centers for Disease Control and Prevention, 2014). Drug use was assessed with a question asking whether marijuana, cocaine, heroin, or a different drug had been used in the past 30 days. Non-marijuana drugs were reported infrequently and therefore collapsed into an “other drug” category.
Demographic characteristics
Participants were asked about their age, marital (and cohabitation) status, living situation (whether housed or living in a shelter, temporarily staying with friends/family, or homeless), educational attainment, weekly income and weekly hours worked, country of origin, years living in the United States, and language spoken (English and Spanish).
Data analysis
Means and percentages were calculated to describe demographic characteristics, social stressors, substance use, and mental health outcomes. One-sample tests of proportions and chi-square tests were calculated to describe the prevalence of depression and anxiety across demographic characteristics, and to assess their associations with social stressors and substance use. Finally, comorbidity of depression and anxiety were examined by assessing the correlation between depression and anxiety. All data analysis was performed using Stata 14 (StataCorp, 2015).

Discussion
This study is one of the first to describe the patterns of depression and anxiety in a sample of Latino day laborers. Men reported high rates of moderate to severe depression (39%) and anxiety (25%). Higher levels of depression and anxiety symptoms were associated with being single, homeless or living in temporary housing, experiencing discrimination, higher levels of acculturation stress, and marijuana use. While tobacco and unhealthy alcohol use were very common in this sample (39% and 66%, respectively), they were not associated with depression and anxiety. These findings build on prior literature and suggest that depression and anxiety are common among Latino day laborers and associated with stressful life experiences that are commonly experienced in this population.
In this recruited sample of Latino day laborers, both depression and anxiety were substantially higher than previously described in the general population of U.S. Latinos, of whom 27% report depression and 2-3% report generalized anxiety disorder (Hong, Walton, Tamaki, & Sabin, 2014; Priest & Denton, 2012; Wassertheil-Smoller et al., 2014). Consistent with prior literature, comorbidity between depression and anxiety was common in this sample (Gorman, 1996; Hirschfield, 2001). Although few studies have documented patterns of both depression and anxiety in day laborers, these findings align with previous research reporting high levels of psychological distress, depression, and
Consistent with previous studies on Latino day laborers, very high rates of unhealthy alcohol use (66%) and cigarette smoking (39%) were identified, further highlighting substance use as an important health concern among Latino day laborers. Rates of unhealthy alcohol use were much higher than those described in the general U.S. population, including rates among U.S. Latinos, but were consistent with previous studies of Latino migrant workers and day laborers (Center for Behavioral Health Statistics and Quality [CBHSQ], Substance Abuse and Mental Health Services Administration [SAMHSA], U.S. Department of Health and Human Services [HHS], & Research Triangle Institute [RTI], 2015; Kissinger et al., 2008; Nelson et al., 2012; Organista & Kubo, 2005; Ornelas et al., 2016). Past-month rates of non-marijuana drug use were comparable to rates in the general U.S. population, but lower than those reported in a study of Latino day laborers in Baltimore, Maryland (CBHSQ, SAMHSA, HHS, & RTI, 2015; Negi et al., 2015).
Men in this study reported substantial experience with difficult living conditions, including low incomes, low levels of education, inadequate housing, and limited English proficiency. Consistent with the Minority Stress model, these conditions were compounded by several social stressors that were related to worse mental health (Meyer, 2003). More than half (62%) of the men had experienced discrimination, and those who reported discrimination had higher levels of anxiety than those who did not. Consistent with prior studies showing an association between perceived discrimination and depression, men who reported experiencing discrimination by the police (33%) were significantly more likely to be depressed than those who had not (Finch et al., 2000; Hunte, King, Hicken, Lee, & Lewis, 2013). Those with high acculturation stress were also more likely to report higher levels of depression and anxiety than those with low acculturation stress, similar to findings from a previous study among Latino migrant farmworkers (Finch, Frank, & Vega, 2004).
Despite living in the United States for an average of 16 years, men in this study had very little social support, with half stating that they had only one person (or no one) to listen to them, help them, or otherwise offer social support in various settings. Being married or living with a partner may decrease social isolation and thus protect against poor mental health. However, most participants were living as single (74%), and those who were single or living as single were more depressed than those who were married or living with their partner. These findings were consistent with previous studies among day laborers documenting social isolation and limited social networks, and their association with poor mental and physical health (Negi, 2011; Organista, Ngo, et al., 2017; Steel et al., 2017).
Some limitations should be noted. First, given the cross-sectional design of the study, associations can be reported, but no causal inferences can be made. For example, it cannot be determined from these data whether unstable housing leads to more depressive symptoms or whether the two are associated for another reason. In some cases, men may have reported lower levels of substance use due to social desirability bias. Because the sample was small, the study may not have had the power to detect some smaller effects. Furthermore, recruitment from only one day labor worker center may limit the generalizability of the findings. Participation in the Vida PURA study was voluntary, and participants may have learned that the study was about alcohol use and chosen to enroll (or avoided enrollment) based on that knowledge, leading to potential selection bias.
Conclusions
While future research is needed in larger and more generalizable samples, overall, findings highlight the vulnerability of this population. Specifically, poor mental health outcomes were very common in this sample of Latino day laborers, and were associated with stressful life events that were commonly experienced. Researchers should focus on identifying causal relationships, as well as on the mechanisms via which social stressors may lead to poor mental health. For instance, it would be useful to determine at what point or at what levels acculturation stress and experiences of discrimination lead to poor mental health outcomes, and if increased social support can ameliorate the impact of social stressors on poor mental health. Such studies can help identify targets and timing of interventions with this population. Latino day laborers may benefit from regular screening for common mental health conditions, as well as alcohol and tobacco use, in order to identify men who may need further assessment for mental health and/or substance use treatment. Addressing mental health among day laborers may also require increased access to stable housing and health care for this population. Health professionals and policy makers should consider the burden of Latino immigrants’ stressors on their mental health and work to mitigate these stressors through programs and policies that protect day laborers.
