RESUMO

OBJECTIVES: Understanding how environmental and social stressors cluster is critical to explaining and addressing health disparities. It remains unclear how these stressors cluster at fine spatial resolution in low to medium-income, urban households. We explored patterns of environmental and social exposures at the household-level and potential predictors of these joint exposures in two environmental justice communities in the Greater Boston area. METHODS: We recruited 150 households in Chelsea, MA and the Dorchester neighborhood of Boston, MA, between 2016 and 2019 and collected data on two domains: environmental and social stressor. For each domain, we fit Latent Class Analysis (LCA) models to exposure data to assess intra-domain variability, and cross-classified the resultant classes to identify joint exposure profiles. We compared differences in the distribution of these profiles by participants' demographic and household characteristics using χ2, Fisher's exact, Analysis of Variance, and Kruskal-Wallis tests. RESULTS: We identified two latent classes in each domain: High environmental (n = 90; 60.4%), Low environmental (n = 59; 39.6%), High Social (n = 31; 20.8%), and Low Social (n = 118; 79.2%). Cross-classification yielded four joint exposure profiles: Both Low (n = 46, 30.9%); Both High (n = 18, 12.1%); High environmental-Low Social (n = 72, 48.3%); and Low environmental-High Social (n = 13, 8.7%). Significant group differences were found by housing type (e.g., single-family vs. multi-family) (Fisher's exact p = 0.0016), housing tenure (p = 0.0007), and study site (p < 0.0001). We also observed differences by race/ethnicity, income, and education: households that were Hispanic/Latinx, below the poverty level, and with lower education were more likely to be in the Both High group. CONCLUSIONS: Our analyses confirmed that environmental and social stressors cluster in socially disadvantaged households. Housing type, housing tenure, and location of the residence were also strong predictors of cluster membership, with renter and multi-family residents at risk of high exposures to environmental and social stressors.

RESUMO

BACKGROUND: Both environmental and social factors have been linked to birth weight and adiposity at birth, but few studies consider the effects of exposure mixtures. Our objective was to identify which components of a mixture of neighborhood-level environmental and social exposures were driving associations with birth weight and adiposity at birth in the Healthy Start cohort. METHODS: Exposures were assessed at the census tract level and included air pollution, built environment characteristics, and socioeconomic status. Prenatal exposures were assigned based on address at enrollment. Birth weight was measured at delivery and adiposity was measured using air displacement plethysmography within three days. We used non-parametric Bayes shrinkage (NPB) to identify exposures that were associated with our outcomes of interest. NPB models were compared to single-predictor linear regression. We also included generalized additive models (GAM) to assess nonlinear relationships. All regression models were adjusted for individual-level covariates, including maternal age, pre-pregnancy BMI, and smoking. RESULTS: Results from NPB models showed most exposures were negatively associated with birth weight, though credible intervals were wide and generally contained zero. However, the NPB model identified an interaction between ozone and temperature on birth weight, and the GAM suggested potential non-linear relationships. For associations between ozone or temperature with birth weight, we observed effect modification by maternal race/ethnicity, where effects were stronger for mothers who identified as a race or ethnicity other than non-Hispanic White. No associations with adiposity at birth were observed. CONCLUSIONS: NPB identified prenatal exposures to ozone and temperature as predictors of birth weight, and mothers who identify as a race or ethnicity other than non-Hispanic White might be disproportionately impacted. However, NPB models may have limited applicability when non-linear effects are present. Future work should consider a two-stage approach where NPB is used to reduce dimensionality and alternative approaches examine non-linear effects.

RESUMO

Latino immigrant men are at increased risk for unhealthy alcohol use and related consequences due to social stressors associated with immigration. We assessed the associations of, and examined whether social stressors moderated associations between, alcohol use and alcohol-related consequences in a community-based sample of Latino immigrant men in Washington (N = 187). The mean Alcohol Use Disorders Identification Test Consumption (AUDIT-C) score was 6.3 (scores ≥ 4 indicate unhealthy alcohol use). More than half of the men (61.5%) reported experiencing discrimination in at least one setting and mean acculturative stress score was 18.3 indicating moderate levels of acculturative stress. Linear regression models were fit to assess main effects (associations between both alcohol use and social stressors and alcohol-related consequences) and moderation (whether the association between alcohol use and consequences varied based on experience of social stressors using multiplicative interaction) after adjustment for potential confounders. Alcohol use (ß = 0.47, 95% CI = 0.20-0.73; p = .001), discrimination (ß = 0.85, 95% CI = 0.27-1.43; p = .004), and acculturative stress (ß = 0.13, 95% CI = 0.02-0.24; p = .025) were all associated with increased experience of alcohol-related consequences. The association between alcohol use and alcohol-related consequences was stronger for those with high levels of acculturative stress (p = .025) but not experience of discrimination (p = .587). Findings underscore the importance of social and cultural context in alcohol use and related consequences. Efforts to reduce negative consequences of drinking may include focus on reducing exposure to discrimination and acculturative stress.

RESUMO

BACKGROUND: Social relationships are crucial for well-being and health, and considerable research has established social stressors as a risk for well-being and health. However, researchers have used many different constructs, and it is unclear if these are actually different or reflect a single overarching construct. Distinct patterns of associations with health/well-being would indicate separate constructs, similar patterns would indicate a common core construct, and remaining differences could be attributed to situational characteristics such as frequency or intensity. The current meta-analysis therefore investigated to what extent different social stressors show distinct (versus similar) patterns of associations with well-being and health. METHODS: We meta-analysed 557 studies and investigated correlations between social stressors and outcomes in terms of health and well-being (e.g. burnout), attitudes (e.g. job satisfaction), and behaviour (e.g. counterproductive work behaviour). Moderator analyses were performed to determine if there were differences in associations depending on the nature of the stressor, the outcome, or both. To be included, studies had to be published in peer-reviewed journals in English or German; participants had to be employed at least 50% of a full-time equivalent (FTE). RESULTS: The overall relation between social stressors and health/well-being was of medium size (r = -.30, p < .001). Type of social stressor and outcome category acted as moderators, with moderating effects being larger for outcomes than for stressors. The strongest effects emerged for job satisfaction, burnout, commitment, and counterproductive work behaviour. Type of stressor yielded a significant moderation, but differences in effect sizes for different stressors were rather small overall. Rather small effects were obtained for physical violence and sexual mistreatment, which is likely due to a restricted range because of rare occurrence and/or underreporting of such intense stressors. CONCLUSIONS: We propose integrating diverse social stressor constructs under the term "relational devaluation" and considering situational factors such as intensity or frequency to account for the remaining variance. Practical implications underscore the importance for supervisors to recognize relational devaluation in its many different forms and to avoid or minimize it as far as possible in order to prevent negative health-related outcomes for employees.

RESUMO

BACKGROUND: Previous studies suggest that persistent exposure to social stress in mammals may be associated with multiple physiological effects. Here, we examine the effects of social stress in rats, i.e. repeated social defeat, on behavior, hypothalamic-pituitary-adrenal (HPA)-axis and immune system. METHODS: A resident-intruder paradigm, where an intruder rat was exposed to social stress by a dominant resident rat for 1 hour each day for 7 consecutive days was used. The day after the last stress exposure in the paradigm the data were analyzed. Variation in social interaction was observed manually, whereas locomotion was analyzed off-line by a purpose-made software. Gene expression in the pituitary gland, adrenal gland and myeloid cells isolated from the spleen was measured by qPCR. RESULTS: The exposure to social stress induced decreased weight gain and increased locomotion. An increased nuclear receptor subfamily group C number 1 (NR3C1) expression in the pituitary gland was also shown. In myeloid cells harvested from the spleen, we observed decreased expression of the ß2-adrenergic receptor (ADRB2) and ß-arrestin-2 (ARRB2), but increased expression of interleukin-6 (IL-6). Subsequent analyses in the same cells showed that ARRB2 was negatively correlated with IL-6 following the stress exposure. CONCLUSION: Our results show that that the experience of social stress in the form of repeated social defeat in rats is a potent stressor that in myeloid cells in the spleen promotes persistent inflammatory changes. Future research is needed to examine whether similar inflammatory changes also can explain the impact of social stress, such as bullying and harassment, among humans.

RESUMO

This actigraphy study tests whether daily work stressors (time pressure, social stressors), work resources (control, social support) and mental detachment from work predict sleep quality, when controlling for demands and control after work. Fifty-two railway employees participated during five consecutive workdays by completing diary questionnaires and wearing an actigraphy device. The results confirmed that social stressors from supervisors predicted more frequent sleep fragmentation and lower sleep efficiency the following night. Higher levels of daily time control at work predicted shorter sleep-onset latency and better self-reported sleep quality. Leisure time control as a covariate turned out to be a private resource, followed by fewer awakenings the following night. Detachment after work related negatively to social stressors and time pressure at work but was unrelated to indicators of sleep quality; detachment after work neither mediated nor moderated the relationship between social stressors from supervisors and sleep quality. Work redesign to increase time control and reduce social stressors is recommended to preserve daily recovery in railway employees. Practitioner summary: Sleep is important to renew health- and safety-related resources in railway employees. This diary and actigraphy study shows that higher daily work stressors were antecedents of lower sleep quality the following night, while more time control was followed by better sleep quality. Work redesign could promote health and safety by improving sleep quality.

RESUMO

BACKGROUND: Metal exposure is a public health hazard due to neurocognitive effects starting in early life. Poor socio-economic status, adverse home and family environment can enhance the neurodevelopmental toxicity due to chemical exposure. Disadvantaged socio-economic conditions are generally higher in environmentally impacted areas although the combined effect of these two factors has not been sufficiently studied. METHODS: The effect of co-exposure to neurotoxic metals including arsenic, cadmium, manganese, mercury, lead, selenium, and to socio-economic stressors was assessed in a group of 299 children aged 6-12 years, residing at incremental distance from industrial emissions in Taranto, Italy. Exposure was assessed with biological monitoring and the distance between the home address and the exposure point source. Children's cognitive functions were examined using the Wechsler Intelligence Scale for Children (WISC) and the Cambridge Neuropsychological Test Automated Battery (CANTAB). Linear mixed models were chosen to assess the association between metal exposure, socio-economic status and neurocognitive outcomes. RESULTS: Urinary arsenic, cadmium and hair manganese resulted inversely related to the distance from the industrial emission source (ß - 0.04; 95% CI -0.06, - 0.01; ß - 0.02; 95% CI -0.05, - 0.001; ß - 0.02 95% CI -0.05, - 0.003) while the WISC intellectual quotient and its sub-scores (except processing speed index) showed a positive association with distance. Blood lead and urinary cadmium were negatively associated with the IQ total score and all sub-scores, although not reaching the significance level. Hair manganese and blood lead was positively associated with the CANTAB between errors of spatial working memory (ß 2.2; 95% CI 0.3, 3.9) and the reaction time of stop signal task (ß 0.05; 95% CI 0.02, 0.1) respectively. All the other CANTAB neurocognitive tests did not show to be significantly influenced by metal exposure. The highest socio-economic status showed about five points intellectual quotient more than the lowest level on average (ß 4.8; 95% CI 0.3, 9.6); the interaction term between blood lead and the socio-economic status showed a significant negative impact of lead on working memory at the lowest socio-economic status level (ß - 4.0; 95% CI -6.9, - 1.1). CONCLUSIONS: Metal exposure and the distance from industrial emission was associated with negative cognitive impacts in these children. Lead exposure had neurocognitive effect even at very low levels of blood lead concentration when socio-economic status is low, and this should further address the importance and prioritize preventive and regulatory interventions.

RESUMO

BACKGROUND: Alcohol use is highly prevalent and linked to a wide range of negative outcomes among college students. Although emotion dysregulation has been theoretically and empirically linked to alcohol use, few studies have examined emotion dysregulation stemming from positive emotions. OBJECTIVE: The goal of the current study was to extend extant research by using daily diary methods to examine the potentially moderating role of difficulties regulating positive emotions in the daily relation between positive affect and alcohol use to cope with social and non-social stressors. METHODS: Participants were 165 college students (M age = 20.04; 55.2% male) who completed a baseline questionnaire assessing difficulties regulating positive emotions. Participants then responded to questions regarding state positive emotions and alcohol use once a day for 14 days. RESULTS: Difficulties regulating positive emotions moderated the daily relation between positive affect stemming from social stressors and alcohol use to cope with social stressors. Positive affect stemming from social stressors predicted alcohol use to cope with social stressors with high (but not low) levels of difficulties regulating positive emotions. CONCLUSIONS: Findings underscore the potential utility of targeting difficulties regulating positive emotions in treatments aimed at reducing alcohol use to cope with social stressors among college students.

RESUMO

Ongoing development of brain systems for social behaviour renders these systems susceptible to the influence of stressors in adolescence. We previously found that adult male rats that underwent social instability stress (SS) in mid-adolescence had decreased sexual performance compared with control males (CTL). Here, we test the hypotheses that SS in adolescence decreases the "attractiveness" of male rats as sexual partners compared with CTL rats and that dominance status is a protective factor against the effects of SS. The main prediction was that females would spend more time with CTL males than SS males, and that this bias would be greater for submissive than for dominant rats. Among dominant pairs (n=16), females preferred SS males, spending more time with and visiting more often SS than CTL males (each pair tested 5×), and SS males had shorter latencies to ejaculation, shorter inter-ejaculation intervals, and made more ejaculations compared with CTL males. Among submissive pairs (n=16), females spent more time with, visited more often, and displayed more paracopulatory behaviour with CTL than with SS males, and differences in sexual performance between SS and CTL males were modest and in the opposite direction from that in dominant pairs. The heightened motivation of SS males relative to CTL males for natural rewards may have attenuated differences in sexual performance in a paced mating context. In sum, the experience of stress in adolescence leads to long-lasting changes in males that are perceptible to females, are moderated by social status, and influence sexual behaviour.

RESUMO

OBJECTIVE: Drawing on a sample of hospital physicians, we attempted to determine prospective associations between three job demands, work-related strain and perceived quality of care. DESIGN: Longitudinal follow-up study with with a 1-year time lag. SETTING: Physicians of two acute-care hospitals in Germany (one general urban and one children's hospital). STUDY PARTICIPANTS: Ninety-five physicians filled out a standardized questionnaire. MAIN OUTCOMES MEASURES: Physicians' evaluations of quality of care at both waves. RESULTS: Our results support the hypothesis that job demands directly influence quality of care irrespective of strain. Specifically, high social stressors (ß = -0.15, P = 0.036) and time pressure (ß = -0.19, P = 0.031) were associated with decreased quality of care over time. We additionally observed reversed effects from quality of care at baseline to time pressure at follow-up (ß = -0.35, P = 0.006). Contrary to expectations, physicians' work-related strain did not mediate the job demands-quality of care-relationship, nor were strain-to-stressor effects observed. CONCLUSIONS: Our results corroborate that hospital work environments with high demands have a direct impact on physician-perceived quality of care. In turn, poor care practices contribute to increased job demands. Our findings also emphasize that further understanding is required of how physicians' workplace conditions affect job demands, well-being, and quality of care, respectively.

RESUMO

Many employees in service work are required to work on Saturdays, recovering during work-free Sundays and working again Mondays. We examined the effects of social stressors at work on recovery status at Sunday noon and Monday noon, and investigated if sleep quality mediates the negative effects of social stressors at work on recovery. From Saturday until Monday morning, 41 participants wore actigraphs to measure sleep duration and sleep fragmentation. Social stressors at work were assessed by self-reported questionnaires administered on Saturday. Recovery status was reported Sunday noon and Monday noon. Hierarchical regression analysis revealed that social stressors at work were negatively related to recovery status on Sunday and on Monday. Supporting our assumptions, more social stressors at work predicted higher sleep fragmentation in the night to Monday. A mediation effect of sleep quality, however, was not found. Theoretical and practical implications of these results are discussed.

RESUMO

We investigated whether adolescent male rats show less habituation of corticosterone release than adult male rats to acute vs repeated (16) daily one hour episodes of isolation stress, as well as the role of partner familiarity during recovery on social behavior, plasma corticosterone, and Zif268 expression in brain regions. Adolescents spent more time in social contact than did adults during the initial days of the repeated stress procedures, but both adolescents and adults that returned to an unfamiliar peer after isolation had higher social activity than rats returned to a familiar peer (p=0.002) or undisturbed control rats (p<0.001). Both ages showed evidence of habituation, with reduced corticosterone response to repeated than acute isolation (p=0.01). Adolescents, however, showed sensitized corticosterone release to repeated compared with an acute pairing with an unfamiliar peer during recovery (p=0.03), a difference not found in adults. Consistent with habituation of corticosterone release, the repeated isolation groups had lower Zif268 immunoreactive cell counts in the paraventricular nucleus (p<0.001) and in the arcuate nucleus (p=0.002) than did the acute groups, and adolescents had higher Zif268 immunoreactive cell counts in the paraventricular nucleus than did adults during the recovery period (p<0.001), irrespective of stress history and partner familiarity. Partner familiarity had only modest effects on Zif268 immunoreactivity, and experimental effects on plasma testosterone concentrations were only in adults. The results highlight social and endocrine factors that may underlie the greater vulnerability of the adolescent period of development.

RESUMO

BACKGROUND: African Americans and those of lower socioeconomic status (SES) are at disproportionate risk for hypertension- and cardiovascular-disease-related mortality relative to their counterparts. Progress in reducing these disparities is slowed by the facts that these disparities are difficult to mitigate in older adults and early origins of these disparities are poorly understood. The Social Status Adversity and Health in Daily Life Moments Study aims to precisely understand the proximal cognitive-emotional mechanisms by which unique social exposures disproportionately impacting these populations influence blood pressure (BP) parameters early in the lifespan and determine which individuals are more at risk. METHODS: The study uses ecological momentary assessment (EMA) and ambulatory blood pressure (ABP) monitoring to assess race- and SES-based factors as they manifest in daily life moments alongside simultaneously manifesting cognitive-emotional states and ABP. A sample of 270 healthy African Americans between the ages of 18 and 30 is being recruited to complete two periods of 2-day, 2-night hourly ABP monitoring alongside hourly EMA assessments of socioeconomic strain, unfair treatment, and neighborhood strain during the waking hours. ABP data will be used to calculate ecologically valid measures of BP reactivity, variability, and nocturnal dipping. Other measures include actigraphy equipment worn during the monitoring period and comprehensive assessment of behavioral and psychosocial risk and resilience factors. Multilevel and multiple linear regression analyses will examine which momentary social adversity exposures and cognitive-emotional reactions to these exposures are associated with worse BP parameters and for whom. DISCUSSION: This is the first time that this research question is approached in this manner. The Social Status Adversity and Health in Daily Life Moments Study will identify the cognitive-emotional mechanisms by which the most impactful race- and SES-based exposures influence multiple BP parameters in African American emerging adults. Further, it will identify those most at risk for the health impacts of these exposures. Achievement of these aims will shape the field's ability to develop novel interventions targeting reduction of these exposures and modification of reactions to these exposures as well as attend to those subpopulations most needing intervention within the African American emerging adult population.

RESUMO

This article is part of a Special Issue "Puberty and Adolescence". Learning and memory is affected by a myriad of factors, including exposure to stressors and the corresponding rise in circulating glucocorticoids. Nevertheless, the effects of stressors depend on the sex, species, the type of stressor used, the duration of exposure, as well as the developmental time-point in which stressors are experienced. Effects of stress in adolescence, however, have received less attention than other developmental periods. In adolescence, the hypothalamic-pituitary-adrenal axis and brain regions involved in learning and memory, which also richly express corticosteroid receptors, are continuing to develop, and thus the effects of stress exposures would be expected to differ from those in adulthood. We conclude from a review of the available literature in animal models that hippocampal function is particularly sensitive to adolescent stressors, and the effects tend to be most evident several weeks after the exposure, suggesting stressors alter the developmental trajectory of the hippocampus.

RESUMO

Tools for assessing multiple exposures across several domains (e.g., physical, chemical, and social) are of growing importance in social and environmental epidemiology because of their value in uncovering disparities and their impact on health outcomes. Here we describe work done within the Environmental influences on Child Health Outcomes (ECHO)-wide Cohort Study to build a combined exposure index. Our index considered both environmental hazards and social stressors simultaneously with national coverage for a 10-year period. Our goal was to build this index and demonstrate its utility for assessing differences in exposure for pregnancies enrolled in the ECHO-wide Cohort Study. Our unitless combined exposure index, which collapses census-tract level data into a single relative measure of exposure ranging from 0-1 (where higher values indicate higher exposure to hazards), includes indicators for major air pollutants and air toxics, features of the built environment, traffic exposures, and social determinants of health (e.g., lower educational attainment) drawn from existing data sources. We observed temporal and geographic variations in index values, with exposures being highest among participants living in the West and Northeast regions. Pregnant people who identified as Black or Hispanic (of any race) were at higher risk of living in a "high" exposure census tract (defined as an index value above 0.5) relative to those who identified as White or non-Hispanic. Index values were also higher for pregnant people with lower educational attainment. Several recommendations follow from our work, including that environmental and social stressor datasets with higher spatial and temporal resolutions are needed to ensure index-based tools fully capture the total environmental context.

RESUMO

Purpose: Health disparities in transgender and gender diverse (TGD) veterans compared with cisgender veterans have been documented. However, there is a paucity of literature focused on older TGD veterans. We assessed health conditions and social stressors in older TGD veterans compared with matched cisgender veterans. Methods: Using gender identity disorder diagnosis codes, we identified 1244 TGD veterans (65+ years of age) receiving care in the Veterans Health Administration (VHA) from 2006 to 2018. These TGD veterans were then matched to 3732 cisgender veterans based on age, VHA site, and date of care in VHA. Results: In adjusted models, TGD veterans compared with cisgender veterans were less likely to have alcohol use disorder (adjusted odds ratio [AOR; 95% confidence interval]: [0.70; 0.58-0.85]), drug use disorder (0.59; 0.47-0.74), tobacco use (0.75; 0.65-0.86), and anxiety (0.74; 0.62-0.90). However, compared with cisgender veterans, TGD veterans were more likely to experience depression (1.63; 1.39-1.93), Alzheimer's disease (8.95; 4.25-18.83), cancer (1.83; 1.56-2.14), violence (1.82; 1.14-2.91), social/familial problems (2.45; 1.99-3.02), lack of access to care/transportation (2.23; 1.48-3.37), and military sexual trauma (2.59; 1.93-3.46). Furthermore, compared with cisgender veterans, TGD veterans were more likely to have documentation of a higher count of social stressors: 1 or more stressors (1.64; 1.38-1.95) and 2 or more stressors (1.22; 1.01-1.49). Conclusion: Despite significant disparities in social stressors and health conditions compared with cisgender veterans, TGD veterans had a lower likelihood of substance use and anxiety. Interventions are needed to mitigate social stressors and improve health among the older TGD veteran population.

RESUMO

BACKGROUND: The COVID-19 pandemic has been associated with increased social and economic stressors among pregnant individuals. While community and social services have been available to mitigate stressors in pregnancy (e.g. food insecurity and financial hardship) and reduce the risk of adverse maternal outcomes, it is unclear how the pandemic impacted access to these resources, particularly in communities of color with lower incomes. OBJECTIVE: To examine the experiences accessing community and social service resources during the COVID-19 pandemic among pregnant people of color with low incomes. DESIGN: Participants for this COVID-related qualitative study were recruited from two sources-a prospective comparative effectiveness study of two models of enhanced prenatal care and the California Black Infant Health Program between August and November of 2020. METHODS: We conducted 62 interviews with Medicaid-eligible participants in California's Central Valley. During their interviews, study participants were asked to share their pregnancy-related experiences, including how they felt the pandemic had affected those experiences. RESULTS: We identified two broad themes: challenges with accessing community and social service resources during the pandemic and opportunities for improving access to these resources. Sub-themes related to challenges experienced included difficulty with remote access, convoluted enrollment processes for community and social services, and problems specific to accessing COVID-19 resources (e.g. testing). Sub-themes related to opportunities to improve access included leveraging instrumental support from perinatal staff and informational (e.g. practical) support from other community programs and pregnant peers. Participant recommendations included leveraging opportunities to improve client experiences through increased transparency and better patient-provider communication. CONCLUSION: This study highlights some important trends that emerged with the rollout of remote service delivery for social services among a vulnerable population. Many participants were able to leverage support through other programs and perinatal staff. These individuals identified additional opportunities to improve client experiences that can inform the future implementation of support services for pregnant people.

RESUMO

BACKGROUND: Adolescence represents a critical period characterized by extensive changes across various domains. While some of the changes and behaviors that emerge during this period can have detrimental effects on adolescents' present and future health, mental health disorders continue to constitute a leading cause of morbidity among young individuals. OBJECTIVE: Assess the prevalence and determinants of depression, anxiety, and stress among secondary school students in Saudi Arabia. METHODS: This analytical cross-sectional study utilized an online questionnaire to collect responses from secondary school students in Saudi Arabia. The Arabic version of the Depression, Anxiety, and Stress Scale - 21 Items (DASS-21) was used to measure depression, anxiety, and stress levels. Data were analyzed using IBM Statistical Package for the Social Sciences software (SPSS, version 29.0, IBM Corp., Armonk, NY, USA). The study included 702 participants. RESULTS: The prevalence of anxiety was 35.2%, followed by depression (30.8%) and stress (14.7%). Females had significantly higher anxiety and stress scores than males (P=0.004, and P=0.011, respectively). Students who were bullied in the last 30 days had significantly higher depression, anxiety, and stress scores than those who were not bullied (P<0.001 for all). Participants who experienced physical assault in the last 12 months had significantly higher depression, anxiety, and stress scores than those who did not (P<0.001 for all). Participants who had had fights in the last 12 months had significantly higher depression (P=0.004) and anxiety (P<0.001) scores than those who did not. Participants who felt unsafe on the way to school had significantly higher depression, anxiety, and stress scores than those who did not (P<0.001 for all). CONCLUSION: The study revealed prevalence rates of depression (30.8%), anxiety (35.2%), and stress (14.7%) among secondary school students in Saudi Arabia. The study highlights the importance of addressing social stressors such as bullying and physical assault and promoting a safe and supportive school environment to prevent mental health disorders in this population.

RESUMO

Objective: In this study, we evaluated the role of minority status, as well as pandemic-related social stressors and health disparities on short- and long-term academic performances of college students. Methods: Cross-sectional analysis using descriptive and bivariate statistics were used to identify participants of minority status as well as pandemic-related prevalence of social stressors and health disparities and their roles on academic performance. Results: Poor academic performance was significantly related to being food insecure, experiences of discrimination, serious psychological distress, and low daytime wakefulness during the pandemic but only significantly based on minority status. Grade point average was significantly associated with serious psychological problems among males, independent of race/ethnicity identity. Conclusions: Institutes of higher education, when tasked with developing post-pandemic policies to address equity gaps in academic success, may benefit their students by integrating system-wide holistic approach to support, including interventions on basic needs support and health and resilience building.

RESUMO

Objective: As recognition of the importance of social determinants of mental health has increased, the limitations of clinical competence-enhancing interventions that do not emphasize this approach have emerged. The Cultural Formulation Interview (CFI) is a cultural competence intervention that emerges from a confluence of social medicine and medical anthropology traditions. Limited research has examined how patients respond to CFI questions on social-structural aspects of illness and care to assess whether the CFI adequately elicits information on social determinants of mental health. Methods: Patients' responses during a first intake appointment to three CFI questions on social stressors, supports, or barriers to care from 27 patient-clinician dyads are analyzed through qualitative content analysis. The data come from a hyper-diverse clinical setting in Queens, New York, where no ethnoracial group has a majority and all patient-clinician dyads reflect cross-cultural interactions. Results: At least one social determinant was coded in 89 of all cases, and nearly 44% included themes related to multiple determinants of health. The most-commonly coded theme was social relationships (n = 21), followed by financial instability (n = 7), stigma (n = 5), housing instability (n = 2), and poor access to healthcare, involvement in the criminal justice system, employment instability, area-level poverty, and immigration policies (n = 1 each). Conclusion: Our work shows that social determinants of mental health can be elicited through the CFI. Future work should examine how this information is included in clinicians' formulations and whether the cultural formulation approach would benefit from additional revision to facilitate assessment of socio-structural factors.
