RESUMO

Despite significant historical progress toward gender parity in employment status in the US, women remain more likely to provide domestic labor, creating role competition which may increase depression symptoms. Pro-family employee benefits may minimize the stress of competing roles. We tested whether depressive symptoms were higher among women with vs. without competing roles and whether this effect was greater among women without (vs. with) pro-family benefits. Data included employed women surveyed across 4 waves of the National Longitudinal Survey (2010-2019) (N=9884). Depression symptoms were measured with the Mental Health Inventory (MHI-5). The interaction between competing roles and pro-family employee benefits on depressive symptoms was also compared with non-family-related benefits, using marginal structural models to estimate longitudinal effects in the presence of time-varying confounding. MHI-5 scores were 0.56 points higher (95% CI=0.15, 0.97) among women in competing roles (vs. not). Among women without pro-family benefits, competing roles increased MHI-5 scores by 6.1-points (95% CI=1.14, 11.1). In contrast, there was no association between competing roles and MHI-5 scores among women with access to these benefits (MHI-5 difference=0.44; 95% CI=-0.2, 1.0). Results were similar for non-family-related benefits. Dual workplace and domestic labor role competition increases women's depression symptoms, though broad availability of workplace benefits may attenuate that risk.

RESUMO

BACKGROUND: Spatial epidemiology has emerged as an important subfield of epidemiology over the past quarter century. We trace the origins of spatial epidemiology and note that its emergence coincided with technological developments in spatial statistics and geography. We hypothesize that spatial epidemiology makes important contributions to descriptive epidemiology and analytic risk-factor studies but is not yet aligned with epidemiology's current focus on causal inference and intervention. METHODS: We conducted a systematic review of studies indexed in PubMed that used the term "spatial epidemiolog*" in the title, abstract, or keywords. Excluded articles were not written in English, examined disease in animals, or reported biologic pathogen distribution only. We coded the included papers into five categories (review, demonstration of method, descriptive, analytic, and intervention) and recorded the unit of analysis (i.e., individual vs. ecological). We additionally examined articles coded as analytic ecologic studies using scales for lexical content. RESULTS: A total of 482 articles met the inclusion criteria, including 76 reviews, 117 demonstrations of methods, 122 descriptive studies, 167 analytic studies, and 0 intervention studies. Demonstration studies were most common from 2006 to 2014, and analytic studies were most common after 2015. Among the analytic ecologic studies, those published in later years used more terms relevant to spatial statistics (incidence rate ratio =1.3; 95% confidence interval [CI] = 1.1, 1.5) and causal inference (incidence rate ratio =1.1; 95% CI = 1.1, 1.2). CONCLUSIONS: Spatial epidemiology is an important and growing subfield of epidemiology. We suggest a re-orientation to help align its practice with the goals of contemporary epidemiology.

RESUMO

Epidemiologic studies in the United States routinely report a lower or equal prevalence of major depressive disorder (MDD) for Black people relative to White people. Within racial groups, individuals with greater life stressor exposure experience greater prevalence of MDD; however, between racial groups this pattern does not hold. Informed by theoretical and empirical literature seeking to explain this "Black-White depression paradox," we outline 2 proposed models for the relationships between racial group membership, life stressor exposure, and MDD: an effect modification model and an inconsistent mediator model. Either model could explain the paradoxical within- and between-racial group patterns of life stressor exposure and MDD. We empirically estimated associations under each of the proposed models using data from 26,960 self-identified Black and White participants in the National Epidemiologic Survey on Alcohol and Related Conditions III (United States, 2012-2013). Under the effect modification model, we estimated relative risk effect modification using parametric regression with a cross-product term, and under the inconsistent mediation model, we estimated interventional direct and indirect effects using targeted minimum loss-based estimation. We found evidence of inconsistent mediation (i.e., direct and indirect effects operating in opposite directions), suggesting a need for greater consideration of explanations for racial patterns in MDD that operate independent of life stressor exposure. This article is part of a Special Collection on Mental Health.

RESUMO

Although the literature on the differences between Black people and White people in terms of differences in major depressive disorder and related self-reported symptoms is robust, less robust is the literature on how these outcomes are patterned within the US Black population and why differences exist. Given increased ethnic diversity of Black Americans due to increases in immigration, continued aggregation may mask differences between Black ethnic-immigrant groups and Black Americans with more distant ancestral ties to Africa (African Americans). The purpose of this narrative review was to comprehensively synthesize the literature on depression and related symptoms within the US Black population across immigration- and ethnicity-related domains and provide a summary of mechanisms proposed to explain variation. Findings revealed substantial variation in the presence of these outcomes within the US Black population by nativity, region of birth, age at immigration, and Caribbean ethnic origin. Racial context and racial socialization were identified as important, promising mechanisms for better understanding variations by region of birth and among those born or socialized in the United States, respectively. Findings warrant data collection efforts and measurement innovation to better account for within-racial differences in outcomes under study. A greater appreciation of the growing ethnic-immigrant diversity within the US Black population may improve understanding of how racism differentially functions as a cause of depression and related symptoms within this group.

RESUMO

PURPOSE: Numerous investigations have sought to understand why Black Americans have a lower prevalence of major depressive disorder (MDD) than white Americans, yet fewer have explored within-racial group variation or its causes. Limited extant evidence indicates that US-born Caribbeans have higher levels of MDD relative to African Americans. Among African Americans, racial identity is considered protective against depression, yet it is unclear how it functions among Black Americans with recent immigrant origins. We examined the extent to which differential effects of racial identity on MDD by ethnic origin explain the elevated prevalence among US-born Caribbeans relative to all other US-born Black Americans. METHODS: With data from the largest nationally representative study of Black mental health, log-binomial models assessed effect modification of ethnic origin (Caribbean, non-Caribbean) on the relationship between racial identity and MDD. Separate models evaluated four indicators of racial identity-"closeness to Black people," "importance of race to one's identity," "belief that one's fate is shared with other Black people," and "Black group evaluation." RESULTS: Belief in "shared fate" was positively associated with MDD for US-born Caribbeans alone (PR = 3.43, 95% CI 1.87, 6.27). Models suggested that "importance of race" and "Black group evaluation" were detrimental for Caribbeans, yet protective for non-Caribbeans. "Closeness" appeared protective for both groups. CONCLUSION: Findings suggest that the protective effect of racial identity against MDD among US-born Black Americans may depend on both ethnic origin and the operationalization of racial identity. Results provide new insight into the role of racial identity on depression and suggest promising directions for future research.

RESUMO

Wage theft - employers not paying workers their legally entitled wages and benefits - costs workers billions of dollars annually. We tested whether preventing wage theft could increase U.S. life expectancy and decrease inequities therein. We obtained nationally representative estimates of the 2001-2014 association between income and expected age at death for 40-year-olds (40 plus life expectancy at age 40) compiled from tax and Social Security Administration records, and estimates of the burden of wage theft from several sources, including estimates regarding minimum-wage violations (not paying workers the minimum wage) developed from Current Population Survey data. After modeling the relationship between income and expected age at death, we simulated the effects of scenarios preventing wage theft on mean expected age at death, assuming a causal effect of income on expected age at death. We simulated several scenarios, including one using data suggesting minimum-wage violations constituted 38% of all wage theft and caused 58% of affected workers' losses. Among women in the lowest income decile, mean expected age at death was 0.17 years longer in the counterfactual scenario than observed (95% confidence interval [CI]: 0.11-0.22), corresponding to 528,685 (95% CI: 346,018-711,353) years extended in the total 2001-2014 age-40 population. Among men in the lowest decile, the estimates were 0.12 (95% CI: 0.07-0.17) and 380,502 (95% CI: 229,630-531,374). Moreover, among women, mean expected age at death in the counterfactual scenario increased 0.16 (95% CI: 0.06-0.27) years more among the lowest decile than among the highest decile; among men, the estimate was 0.12 (95% CI: 0.03-0.21).

RESUMO

PURPOSE: While the association between intimate partner violence (IPV) and stress is well documented, the directionality of this relationship is unclear. We use an adjusted longitudinal study design to better understand if stressful life events in the home precipitate or exacerbate intimate partner violence (IPV) and if experiences of IPV, in turn, increase levels of perceived stress. METHODS: Longitudinal data were collected among married women in rural Pakistan at 12 and 24 months postpartum (N = 815). Adjusted Poisson and linear regression models were used to examine stressful life events, past year IPV and severity (number and frequency of violent acts), and perceived stress (Cohen Perceived Stress Scale). RESULTS: At 12 months postpartum, the prevalence of past year physical, psychological, and sexual IPV was 8.5%, 25.7%, and 25.1%, respectively, with 42.6% experiencing any IPV. After adjustment, stressful life events were associated with a subsequent increased likelihood of all IPV types and increased severity of all but physical IPV. Any past year IPV (versus none) and greater IPV severity were associated with 3.43 (95% CI 2.33-4.52) and 2.57 (95% CI 1.87-3.27) point subsequent increases in perceived stress. Physical, psychological, and sexual IPV and their respective severities were all independently associated with increased perceived stress. CONCLUSIONS: Among postpartum women in Pakistan, stressful life events increase the likelihood of IPV and, in turn, experiences of IPV increase stress levels. Support to families undergoing stressful circumstances may be critical to reducing women's IPV exposure and resulting elevated stress.

RESUMO

The depression gap refers to higher rates of depression among women than men. Change in the depression gap over time might elucidate social causes of this disparity-such as unequal college attendance or employment status. We conducted a meta-regression analysis to estimate variation in the depression gap over time by age, accounting for potential sources of variation between studies. Electronic databases and bibliographies were searched for English-language studies from January 1980 through October 2019; 144 independent estimates from US-representative samples met selection criteria (n = 813,189). The depression gap was summarized as prevalence ratios among studies using diagnostic instruments and as standardized mean differences among symptom-based studies. Primary study measures were baseline study year (range, 1982-2017) and age (age groups ranging, in years, from 10-59 and 60 or older). Compared with respondents aged ≥60 years, depression prevalence was greater among respondents aged 10-19 (prevalence ratio = 1.26, 95% confidence interval: 1.02, 1.56). Over time, the depression gap did not change among adults, but it increased among adolescents (age-by-time interaction prevalence ratio = 1.05, 95% confidence interval: 1.01, 1.08). Results were similar for symptom-based studies. The present study finds no evidence of a change in the depression gender gap for US adults; however, the gap increased among adolescents. Greater attention to factors driving this widening disparity in adolescent depression is needed.

RESUMO

BACKGROUND: Social stratification is a well-documented determinant of mental health. Traditional measures of stratification (e.g., socioeconomic status) reduce dynamic social processes to individual attributes downstream of mechanisms that generate stratification. In this study, we measure one process theorized to generate and reproduce social stratification-economic exploitation-and explore its association with mental health. METHODS: Data are from the 1983 to 2017 waves of the Panel Study of Income Dynamics, a nationally representative cohort study (baseline N = 3059). We operationalized "unconcealed exploitation" as the percentage of individuals' labor income they were hypothetically not paid for productive hours. We ascertained psychologic distress and mental illness with the Kessler-6 (K6) scale. RESULTS: We fit inverse probability-weighted marginal structural models and found that for each unit increase in unconcealed exploitation, psychologic distress increased by 1.6 points (95% confidence interval = 0.71, 2.5) on the K6 scale and the odds of mental illness tripled (odds ratio = 3.0, 95% confidence interval = 1.5, 6.1). Results were not driven entirely by overwork and were robust to different inverse probability-weighted estimation strategies and sensitivity analyses. CONCLUSIONS: Exploitation is associated with mental illness. Focusing on exploitation rather than its consequences (e.g., socioeconomic status), shifts attention to a structural process that may be a more appropriate explanatory mechanism, and a more pragmatic intervention target, for mental illness.

RESUMO

BACKGROUND: Adverse Childhood Experiences (ACEs) are a common pathway to adult depression. This pathway is particularly important during the perinatal period when women are at an elevated risk for depression. However, this relationship has not been explored in South Asia. This study estimates the association between ACEs and women's (N = 889) depression at 36 months postpartum in rural Pakistan. METHOD: Data come from the Bachpan Cohort study. To capture ACEs, an adapted version of the ACE-International Questionnaire was used. Women's depression was measured using both major depressive episodes (MDE) and depressive symptom severity. To assess the relationship between ACEs and depression, log-Poisson models were used for MDE and linear regression models for symptom severity. RESULTS: The majority (58%) of women experienced at least one ACE domain, most commonly home violence (38.3%), followed by neglect (20.1%). Women experiencing four or more ACEs had the most pronounced elevation of symptom severity (ß = 3.90; 95% CL = 2.13, 5.67) and MDE (PR = 2.43; 95% CL = 1.37, 4.32). Symptom severity (ß = 2.88; 95% CL = 1.46, 4.31), and MDE (PR = 2.01; 95% CL = 1.27, 3.18) were greater for those experiencing community violence or family distress (ß = 2.04; 95%; CL = 0.83, 3.25) (PR = 1.77; 95% CL = 1.12, 2.79). CONCLUSIONS: Findings suggest that ACEs are substantively distinct and have unique relationships to depression. They signal a need to address women's ACEs as part of perinatal mental health interventions and highlight women's lifelong experiences as important factors to understanding current mental health. TRIAL REGISTRATION: NCT02111915 . Registered 11 April 2014. NCT02658994 . Registered 22 January 2016. Both trials were prospectively registered.

RESUMO

BACKGROUND: Intimate partner violence (IPV) is highly prevalent globally and associated with adverse mental health outcomes among women. In IPV-endemic contexts like Bangladesh, previous research has found no association between low levels of IPV and depression. Although IPV and attitudes justifying IPV against women are highly prevalent in this context, nothing is known about how related contextual norms affect associations between individual-level IPV exposure and depression. The present study examines if village-level IPV norms, characterized using village-level (Level 2) prevalence of a) IPV-justifying attitudes (injunctive norms) and b) physical IPV (descriptive norms), modifies the individual-level (Level 1) associations between the severity of recent IPV and major depressive episode (MDE) among women in rural Bangladesh. METHODS: Data were drawn from a nationally-representative sample consisting of 3290 women from 77 villages. Multilevel models tested cross-level interactions between village-level IPV norms and recently experienced individual-level IPV on the association with past 30-day MDE. RESULTS: The prevalence of IPV was 44.4% (range: 9.6-76.2% across villages) and attitudes justifying IPV ranged from 1.6% to 49.8% across villages. The prevalence of MDE was 16.8%. The risk of MDE at low levels of IPV severity (versus none) was greater in villages with the least tolerant attitudes toward IPV compared to villages where IPV was more normative, e.g., interaction RR = 1.42 (95% CI: 0.64, 3.15) for low physical IPV frequency and injunctive norms. CONCLUSIONS: The association between IPV and depression may be modified by contextual-level IPV norms, whereby it is exacerbated in low-normative contexts.

RESUMO

"The mission of the Diversity and Inclusion Committee (D&I) in the Society for Epidemiologic Research is to foster the diversity of our membership and work towards the engagement of all members, from diverse backgrounds at all stages of their careers, in the Society's activities, with the intent of enhancing discovery in public health." As a foundational step in implementing our mission, the D&I Committee conducted a survey of SER membership. Here we report on the efforts we have undertaken to expand the diversity and inclusiveness of our Society and our aspirations for future efforts in support of D&I. Early on, we established the SERvisits program to conduct outreach to institutions and students that have historically been underrepresented at SER; we hope this program continues to grow in its reach and impact. We have also taken steps to increase the inclusiveness of SER activities, for example, by engaging members on issues of D&I through symposia and workshops at SER annual meetings and through social media. DeVilbiss et al. (Am J Epidemiol. 2020;189(10):998-1010) have demonstrated that there is substantial room for improvement with regards to diversity and inclusion within SER. We invite SER members to become involved and collaborate on this long-term goal.

RESUMO

PURPOSE: Epidemiologic studies document a lower prevalence of major depression in Blacks than Whites in the United States. This is paradoxical from the perspective of social stress theory. A long-standing claim in the (clinical) literature is that Blacks express depression more somatically than Whites. If true, the diagnostic algorithm may undercount depression in Blacks, since the screening symptoms privilege the psychological rather than somatic dimensions of depression. We test hypotheses that (1) Blacks express depression more somatically than Whites which (2) reduces their likelihood of endorsing screening symptoms, thereby undercounting Blacks' depression and explaining the Black-White depression paradox. METHODS: We use cross-sectional data collected in 1991-92 from the National Longitudinal Alcohol Epidemiologic Survey (n = 42,862) among Blacks and Whites endorsing at least one past-12-month depression symptom. We compare groups on depression somatization and test whether greater somatization in Blacks leads to lower endorsement of psychological screening symptoms, and therefore under-diagnosis. RESULTS: Blacks have higher mean depression somatization scores than Whites (0.28, SE 0.04 vs. 0.15, SE 0.02), t(122) = - 2.15, p = 0.03. This difference is small and driven by Blacks' higher endorsement of 1 somatic symptom (weight/appetite change) and Whites' greater propensity to endorse psychological symptoms. However, Blacks have the same odds as Whites of endorsing screening symptoms, before and after adjusting for somatization. CONCLUSIONS: We find minimal evidence that Blacks express depression more somatically than Whites. Furthermore, this small difference does not appear to inhibit endorsement of diagnostic depression screening symptoms among Blacks, and therefore does not resolve the Black-White depression paradox.

RESUMO

BACKGROUND: We draw on a relational theoretical perspective to investigate how the social division and structure of labor are associated with serious and moderate mental illness and binge and heavy drinking. METHODS: The Panel Study of Income Dynamics and the Occupational Information Network were linked to explore how occupation, the productivity-to-pay gap, unemployment, the gendered division of domestic labor, and factor-analytic and theory-derived dimensions of work are related to mental illness and drinking outcomes. RESULTS: Occupations involving manual labor and customer interaction, entertainment, sales, or other service-oriented labor were associated with increased odds of mental illness and drinking outcomes. Looking for work, more hours of housework, and a higher productivity-to-pay gap were associated with increased odds of mental illness. Physical/risky work was associated with binge and heavy drinking and serious mental illness; technical/craft work and automation were associated with binge drinking. Work characterized by higher authority, autonomy, and expertise was associated with lower odds of mental illness and drinking outcomes. CONCLUSIONS: Situating work-related risk factors within their material context can help us better understand them as determinants of mental illness and identify appropriate targets for social change.

RESUMO

BACKGROUND: Although pregnancy loss affects one-third of pregnancies, the associated signs/symptoms have not been fully described. Given the dynamic nature of maternal physiologic adaptation to early pregnancy, we posited the relationships between signs/symptoms and subsequent loss would vary weekly. METHODS: In a preconception cohort with daily follow-up, pregnancies were ascertained by self-administered sensitive home pregnancy tests on day of expected menses. We evaluated the effects of weekly time-varying signs/symptoms (including vaginal bleeding, lower abdominal cramping, and nausea and/or vomiting) on pregnancy loss <20 weeks in Cox proportional hazards models and calculated the week-specific probability of loss by the presence/absence of each sign/symptom. RESULTS: Of 341 pregnancies ascertained by home pregnancy test, 95 (28%) ended in loss. Relationships between signs/symptoms and loss varied across time since first positive pregnancy test. In the first week following pregnancy confirmation, when many losses occurred, bleeding [hazard ratio (HR) 8.7, 95% confidence interval (CI) 4.7, 16.0] and cramping (HR 1.8, 95% CI 1.2, 2.7) were associated with loss even when accompanied by nausea and/or vomiting (HR 5.2, 95% CI 2.6, 10.5). After the second week, new relationships emerged with nausea and/or vomiting inversely associated (HR range 0.6-0.3, all 95% CI upper bounds <1.00) and bleeding no longer associated with loss. Probabilities of loss of ranged from 78% (95% CI 59%, 96%) with bleeding present in week 1 to 8% (95% CI 5%, 12%) with nausea/vomiting present in week 5. CONCLUSIONS: Relationships between signs/symptoms and pregnancy loss vary in early pregnancy possibly reflecting maternal physiologic response.

RESUMO

PURPOSE: Major epidemiologic studies in the US reveal a consistent "paradox" by which psychiatric outcomes such as major depressive disorder (MDD) are less prevalent among Blacks relative to Whites, despite greater exposure to social and economic stressors and worse physical health outcomes. A second paradox, which has received less attention and has never been systematically documented, is the discrepancy between these patterns and Black-White comparisons in psychological distress, which reveal consistently higher levels among Blacks. By systematically documenting the latter paradox, this paper seeks to inform efforts to explain the first paradox. METHODS: We conduct a systematic review of the literature estimating the prevalence of MDD and levels of psychological distress in Blacks and Whites in the US. RESULTS: The literature review yielded 34 articles reporting 54 relevant outcomes overall. Blacks have a lower prevalence of MDD in 8 of the 9 comparisons observed. In contrast, Blacks have higher levels of psychological distress (in terms of "high distress" and mean scores) than Whites in 42 of the 45 comparisons observed. Tests of statistical significance, where available, confirm this discrepant pattern. CONCLUSIONS: A systematic review of the epidemiologic evidence supports the existence of a "double paradox" by which Blacks' lower prevalence of MDD relative to Whites' is inconsistent with both the expectations of social stress theory and with the empirical evidence regarding psychological distress. Efforts to resolve the Black-White depression paradox should account for the discordant distress results, which seem to favor artifactual explanations.

RESUMO

Child marriage (before age 18) is a risk factor for intimate partner violence (IPV) against women. Worldwide, Bangladesh has the highest prevalence of IPV and very early child marriage (before age 15). How the community prevalence of very early child marriage influences a woman's risk of IPV is unknown. Using panel data (2013-2014) from 3,355 women first married 4-12 years prior in 77 Bangladeshi villages, we tested the protective effect of a woman's later first marriage (at age 18 or older), the adverse effect of a higher village prevalence of very early child marriage, and whether any protective effect of a woman's later first marriage was diminished or reversed in villages where very early child marriage was more prevalent. Almost one-half (44.5 %) of women reported incident physical IPV, and 78.9 % had married before age 18. The village-level incidence of physical IPV ranged from 11.4 % to 75.0 %; the mean age at first marriage ranged from 14.8 to 18.0 years. The mean village-level prevalence of very early child marriage ranged from 3.9 % to 51.9 %. In main-effects models, marrying at 18 or later protected against physical IPV, and more prevalent very early child marriage before age 15 was a risk factor. The interaction of individual later marriage and the village prevalence of very early child marriage was positive; thus, the likely protective effect of marrying later was negated in villages where very early child marriage was prevalent. Collectively reducing very early child marriage may be needed to protect women from IPV.

RESUMO

Despite a well-established social gradient for many mental disorders, there is evidence that individuals near the middle of the social hierarchy suffer higher rates of depression and anxiety than those at the top or bottom. Although prevailing indicators of socioeconomic status (SES) cannot detect or easily explain such patterns, relational theories of social class, which emphasise political-economic processes and dimensions of power, might. We test whether the relational construct of contradictory class location, which embodies aspects of both ownership and labour, can explain this nonlinear pattern. Data on full-time workers from the National Epidemiologic Survey on Alcohol and Related Conditions (n = 21859) show that occupants of contradictory class locations have higher prevalence and odds of depression and anxiety than occupants of non-contradictory class locations. These findings suggest that the effects of class relations on depression and anxiety extend beyond those of SES, pointing to under-studied mechanisms in social epidemiology, for example, domination and exploitation.

RESUMO

OBJECTIVE: To evaluate the accuracy of self-reported diabetes among multi-ethnic older adults by psychosocial factors and assess predictors of diabetes risk, diagnosis, and control. DESIGN AND METHODS: The 2006 Health and Retirement Study (N=5,594) was used to determine agreement between self-reported diabetes and measured diabetes (HbA1c> or = 6.5%) by age, sex, race/ethnicity, nativity, education, health insurance coverage, body mass index, depressive symptoms, and prior report of racial discrimination. We also examined associations between these factors and pre-diabetes (HbA1c > or = 6.0-<6.5%) among individuals without diabetes, and those with undiagnosed and poorly controlled (HbA1c > or = 8.0%) diabetes. RESULTS: Accuracy of self-reported diabetes was good (ie, sensitivity > or = 80% and specificity > or = 95%) among all demographic subgroups and across most social strata. Among those who reported racial discrimination, sensitivity of self-reported diabetes was lower among Blacks who reported racial discrimination in comparison to Blacks who did not report racial discrimination (82.7% vs 89.0%) an association that was marginally statistically significant (P=.05). Blacks and Hispanics had higher odds of pre-diabetes, undiagnosed diabetes, and poor glycemic control. CONCLUSIONS: Self-reported diabetes corresponded well with HbAlc assessed disease for all social strata examined in this sample of multi-ethnic older adults. Blacks with a history of racial discrimination may be less likely to know diabetes status.
