RESUMO

Identifying subpopulations that are particularly vulnerable to long-term adverse health consequences of disaster-related trauma is needed. We examined whether adverse childhood experiences (ACEs) potentiate the association between disaster-related trauma and subsequent cognitive disability among older adult disaster survivors. Data were from a prospective cohort study of older adults who survived the 2011 Great East Japan Earthquake. The baseline survey pre-dated the disaster by 7 months. We included participants who completed follow-up surveys (2013 and 2016) and did not have a cognitive disability before the disaster (n = 602). Disaster-related traumas (i.e., home loss, loss of friends or pets) and ACEs were retrospectively assessed in 2013. Cognitive disability levels in 2016 were objectively assessed. After adjusting for pre-disaster characteristics using a machine learning-based estimation approach, home loss (0.19, 95% confidence interval (CI): 0.09, 0.28) was, on average, associated with greater cognitive disability. Among individuals with ACEs, home loss was associated with even higher cognitive disability levels (0.64, 95% CI: 0.24, 1.03). Losses of friends (0.18, 95% CI: 0.05, 0.32) and pets (0.13, 95% CI: 0.02, 0.25) were associated with higher cognitive disability levels only among those with ACEs. Our findings suggest that individuals with a history of ACEs may be particularly vulnerable to adverse health consequences related to disasters.

RESUMO

Neighborhood safety is defined inconsistently across epidemiologic studies - a conceptual problem that results in incomparable measurements, hampering the design of health interventions. Using child behavior problems (measured via the Child Behavior Checklist) as the outcome of interest, this study directly compared four measures of neighborhood safety: two of experienced safety and two of perceived safety, with each one measured at family and community levels. These included children's direct experience of harm, parental perceptions, community crime statistics, and community perceptions. In a sample of 3291 ten-year-olds from the Generation R cohort (living in municipal Rotterdam, Netherlands, 2013), all four measures were correlated (χ2 ≥ 9.2, P < 0.002 in pairwise chi-square comparisons), but ultimately identified different levels of risk for behavioral health. Direct experiences of harm, parental perceptions, and community crime statistics were all associated with increased child internalizing behaviors (ß = 3.12, ß = 2.10, and ß = 1.77, respectively), while only experiences of harm and parental perceptions were associated with increased externalizing behaviors (ß = 2.75 and ß = 1.31, respectively). These results provide novel evidence that the conceptual distinctions underlying different measures of neighborhood safety are meaningful for child mental health and should be considered in intervention design.

RESUMO

BACKGROUND & PURPOSE: Adolescent housing insecurity is a dynamic form of social adversity that impacts child health outcomes worldwide. However, the means by which adolescent housing insecurity may become biologically embedded to influence health outcomes over the life course remain unclear. Therefore, we aimed to utilize life course perspectives and advanced causal inference methods to evaluate the potential for inflammation to contribute to the biological embedding of adolescent housing insecurity. MATERIALS AND METHODS: Using prospective data from the Great Smoky Mountains Study, we investigated the relationship between adolescent housing insecurity and whole-blood spot samples assayed for C-reactive protein (CRP). Adolescent housing insecurity was created based on annual measures of frequent residential moves, reduced standard of living, forced separation from the home, and foster care. Annual measures of CRP ranged from 0.001 mg/L to 13.6 mg/L (median = 0.427 mg/L) and were log10 transformed to account for positively skewed values. We used g-estimation of structural nested mean models to estimate a series of conditional average causal effects of adolescent housing insecurity on CRP levels from ages 11 to 16 years and interpreted the results within life course frameworks of accumulation, recency, and sensitive periods. PRINCIPAL RESULTS: Of the 1,334 participants, 427 [44.3 %] were female. Based on the conditional average causal effect, one exposure to adolescent housing insecurity from ages 11 to 16 years led to a 6.4 % (95 % CI = 0.69 - 12.4) increase in later CRP levels. Exposure at 14 years of age led to a 27.9 % increase in CRP levels at age 15 (95 % CI = 6.5 - 53.5). Recent exposures to adolescent housing insecurity (<3 years) suggested stronger associations with CRP levels than distant exposures (>3 years), but limited statistical power prevented causal conclusions regarding recency effects at the risk of a Type II Error. MAJOR CONCLUSIONS: These findings highlight inflammation-as indicated by increased CRP levels-as one potential mechanism for the biological embedding of adolescent housing insecurity. The results also suggest that adolescent housing insecurity-particularly recent, repeated, and mid-adolescent exposures-may increase the risk of poor health outcomes and should be considered a key intervention target.

RESUMO

BACKGROUND: Significant early life adversities, such as childhood sexual and physical/emotional abuse, are associated with risk of poor health outcomes but are understudied risk factors for post-COVID-19 conditions. In this prospective study, we examined the associations between combined exposure to sexual and physical/emotional abuse during childhood with risk of post-COVID-19 conditions in adulthood. Additionally, we explored the extent to which lifestyle, health-related and psychological factors explain this association. METHODS: We used data from three large, ongoing cohorts: Nurses' Health Study (NHS)-II, NHS3, and the Growing Up Today Study. Between April 2020 and November 2021, participants responded to periodic COVID-19 surveys. Participants were included if they responded to a questionnaire about childhood abuse, subsequently tested positive for SARS-CoV-2 infection and responded to questions about post-COVID-19 conditions. Childhood sexual abuse was measured before the COVID-19 pandemic with the Sexual Maltreatment Scale of the Parent-Child Conflict Tactics Scale, and physical/emotional abuse was measured with the Physical and Emotional Abuse Subscale of the Childhood Trauma Questionnaire. Post-COVID-19 conditions, defined as COVID-19-related symptoms lasting 4 weeks or longer (e.g., fatigue, dyspnea), were self-reported in the final COVID-19 questionnaire in November 2021. Sexual abuse and physical/emotional abuse were examined separately and jointly in relation to post-COVID-19 conditions. Data on key lifestyle (e.g., cigarette smoking), health-related (e.g., asthma, diabetes), and psychological factors (e.g., depression and anxiety) were obtained. RESULTS: Of 2851 participants, the mean age (range) was 55.8 (22.0-75.0) years; 2789 (97.8 %) were females, and 2750 (96.5 %) were whites. We observed a dose-dependent relationship between severity of childhood abuse and post-COVID conditions (p-trend:<0.0001); participants with severe versus no childhood abuse had a 42 % higher subsequent risk of post-COVID conditions [relative risk (95 % confidence interval): 1.42 (1.25 to 1.61)]. Key lifestyle, health-related, and psychological factors mediated 25.5 % of this association. Both sexual and physical/emotional abuse, were independently associated with post-COVID conditions. CONCLUSIONS: In this prospective study of 2851 participants, childhood abuse was significantly associated with increased risk of post-COVID conditions. Biological pathways connecting childhood abuse with subsequent risk of post-COVID conditions should be investigated.

RESUMO

BACKGROUND: Disability is associated with increased risk of drug overdose mortality, but previous studies use coarse and inconsistent methods to identify adults with disabilities. This investigation makes use of the U.S. Department of Health and Human Services disability questions to estimate the risk of drug overdose death among U.S. adults using seven established disability categories. METHODS: The longitudinal Mortality Disparities in American Communities study was used to determine disability status among a nationally representative sample of adults age ≥18 in 2008 (n = 3,324,000). Through linkage to the National Death Index, drug overdose deaths were identified through 2019. Adults in mutually-exclusive disability categories (hearing, vision, cognitive, mobility, complex activity, ≥2 limitations) were compared to adults with no reported disabilities using adjusted hazard ratios (aHRs) and controlling for demographic and socioeconomic covariates. RESULTS: The risk of drug overdose death varied considerably by disability type, as adults in some disability categories displayed only marginally significant risk, while adults in other disability categories displayed substantially elevated risk. Compared to non-disabled adults, the risk of drug overdose death was highest among adults with ≥2 limitations (aHR = 3.0, 95% CI = 2.8-3.3), cognitive limitation (aHR = 2.6, 95% CI = 2.3-2.9), mobility limitation (aHR = 2.6, 95% CI = 2.3-2.9), complex activity limitation (aHR = 2.3, 95% CI = 1.8-2.9), hearing limitation (aHR = 1.6, 95% CI = 1.3-1.9), and vision limitation (aHR = 1.3, 95% CI = 1.0-1.7). CONCLUSIONS: The examination of specific disability categories revealed unique associations that were not apparent in previous research. These findings can be used to focus overdose prevention efforts on the populations at greatest risk for drug-related mortality.

RESUMO

PURPOSE: There is widespread recognition of the importance and complexity of measuring neighborhood contexts within research on child psychopathology. In this study, we assessed the cross-sectional associations between two measures of neighborhood quality and internalizing and externalizing behaviors in preadolescence. METHODS: Drawing on baseline data from the Adolescent Brain Cognitive Development Study (n = 10,577 preadolescents), we examined two multi-component assessments of neighborhood quality in relation to children's internalizing and externalizing symptoms: the Area Deprivation Index (ADI), which measures socioeconomic adversity, and the Child Opportunity Index 2.0 (COI), which measures economic, educational, and environmental opportunity. Both measures were categorized into quintiles. We then used mixed-effects linear regression models to examine bivariate and adjusted associations. RESULTS: The bivariate associations displayed strong inverse associations between the COI and ADI and externalizing symptoms, with a graded pattern of fewer externalizing behaviors with increasing neighborhood quality. Only the ADI was associated with externalizing behaviors in models adjusted for child and family characteristics. We did not observe a clear association between either measure of neighborhood quality and internalizing behaviors in bivariate or adjusted models. CONCLUSIONS: Neighborhood quality, as measured by the COI and ADI, was associated with externalizing behaviors in preadolescent children. The association using the ADI persisted after adjustment for family-level characteristics, including financial strain. Our results indicate that different assessments of neighborhood quality display distinct associations with preadolescent behavioral health. Future research is needed to assess the association between neighborhood quality and behavior trajectories and to identify place-based intervention strategies.

RESUMO

BACKGROUND: Previous studies have shown that job strain is associated with low birthweight (LBW), preterm birth (PTB), and small for gestational age (SGA). We conducted a scoping review and meta-analysis to assess the association between job strain and adverse pregnancy outcomes. METHODS: A literature search was performed on PubMed. We included English-language studies that examined the association between job strain (based on the Karasek demand-control model) and pregnancy outcomes. We excluded letters, posters, reviews, and qualitative studies. Random effects meta-analysis was performed. Heterogeneity was assessed using τ2 and I2 statistics. Potential bias was assessed using standard funnel plots. Asymmetry was evaluated by Egger's test. Leave-one-out analysis was performed for sensitivity analyses. RESULTS: Three eligible studies were found for LBW, seven for PTB, and four for SGA. The number of subjects ranged from 135 to 4889, and the prevalence of high job strain ranged from 6.64% to 33.9%. The pooled odds ratio and 95% confidence interval (CI) for LBW, PTB, and SGA were 1.23 (95% CI: 0.97, 1.56), 1.10 (95% CI: 1.00, 1.22), and 1.16 (95% CI: 0.97, 1.39) respectively, indicating modest associations. Heterogeneity for LBW and PTB may not be important but may be moderate for SGA. No publication bias was detected for LBW and PTB, but possible publication bias exists for SGA. CONCLUSION: We found a modest association between job strain and PTB. Since job strain is only one of the many aspects of an unhealthy work environment, interventions that improve working conditions more broadly are needed.

RESUMO

BACKGROUND: Disability is associated with alcohol misuse and drug overdose death, however, its association with alcohol-induced death remains understudied. OBJECTIVE: To quantify the risk of alcohol-induced death among adults with different types of disabilities in a nationally representative longitudinal sample of US adults. METHODS: Persons with disabilities were identified among participants ages 18 or older in the Mortality Disparities in American Communities (MDAC) study (n = 3,324,000). Baseline data were collected in 2008 and mortality outcomes were ascertained through 2019 using the National Death Index. Adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) were estimated for the association between disability type and alcohol-induced death, controlling for demographic and socioeconomic covariates. RESULTS: During a maximum of 12 years of follow-up, 4000 alcohol-induced deaths occurred in the study population. In descending order, the following disability types displayed the greatest risk of alcohol-induced death (compared to adults without disability): complex activity limitation (aHR = 1.7; 95% CI = 1.3-2.3), vision limitation (aHR = 1.6; 95% CI = 1.2-2.0), mobility limitation (aHR = 1.4; 95% CI = 1.3-1.7), ≥2 limitations (aHR = 1.4; 95% CI = 1.3-1.6), cognitive limitation (aHR = 1.2; 95% CI = 1.0-1.4), and hearing limitation (aHR = 1.0; 95% CI = 0.9-1.3). CONCLUSIONS: The risk of alcohol-induced death varies considerably by disability type. Efforts to prevent alcohol-induced deaths should be tailored to meet the needs of the highest-risk groups, including adults with complex activity (i.e., activities of daily living - "ALDs"), vision, mobility, and ≥2 limitations. Early diagnosis and treatment of alcohol use disorder within these populations, and improved access to educational and occupational opportunities, should be considered as prevention strategies for alcohol-induced deaths.

RESUMO

OBJECTIVE: The purpose of this study was to assess differences in reported information about treatment, integration into care, and respect by self-identified Black and White individuals with advanced prostate cancer in the United States. PATIENTS AND METHODS: This is a prospective cohort study of 701 participants (20% identifying as Black) enrolled in the International Registry for Men with Advanced Prostate Cancer at 37 US sites from 2017 to 2022. Participants were asked six questions from the Cancer Australia National Cancer Control Indicators about their experience with care at study enrollment. Prevalence differences by self-reported race were estimated using marginal standardization of logistic-normal mixed effects models (adjusted for age at enrollment and disease state at enrollment), and 95% CIs were estimated using parametric bootstrapping. RESULTS: Most participants reported a high quality of care for each question. Black participants generally reported higher care quality compared with White participants. Black participants reported more frequently that they were offered a written assessment and care plan (71%) compared with White participants (58%; adjusted difference, 13 percentage points; 95% CI, 4-23). Black participants also reported more frequently being given the name of nonphysician personnel who would support them (64%) than White participants (52%; adjusted difference, 10; 95% CI, 1-20). Prevalence differences did not differ by disease state at enrollment. CONCLUSIONS: Black participants generally reported a higher quality of care compared with White participants. This study calls attention to the need to study potential mediating factors and interpersonal aspects of care in this population to improve survivorship.

RESUMO

BACKGROUND: Although investigations have begun to differentiate biological and neurobiological responses to a variety of adversities, studies considering both endocrine and immune function in the same datasets are limited. METHODS: Associations between proximal (family functioning, caregiver depression, and anxiety) and distal (SES-D; socioeconomic disadvantage) early-life adversities with salivary inflammatory biomarkers (IL-1ß, IL-6, IL-8, and TNF-α) and hair HPA markers (cortisol, cortisone, and dehydroepiandrosterone) were examined in two samples of young U.S. children (N = 142; N = 145). RESULTS: Children exposed to higher SES-D had higher levels of TNF-α (B = 0.13, p = 0.011), IL-1ß (B = 0.10, p = 0.033), and DHEA (B = 0.16, p = 0.011). Higher family dysfunction was associated with higher cortisol (B = 0.08, p = 0.033) and cortisone (B = 0.05, p = 0.003). An interaction between SES-D and family dysfunction was observed for cortisol levels (p = 0.020) whereby children exposed to lower/average levels of SES-D exhibited a positive association between family dysfunction and cortisol levels, whereas children exposed to high levels of SES-D did not. These findings were partially replicated in the second sample. CONCLUSIONS: Our results indicate that these biological response systems may react differently to different forms of early-life adversity. IMPACT: Different forms of early-life adversity have varied stress signatures, and investigations of early-life adversities with inflammation and HPA markers are lacking. Children with higher socioeconomic disadvantage had higher TNF-α, IL-1ß, and DHEA. Higher family dysfunction was associated with higher hair cortisol and cortisone levels, and the association between family dysfunction and cortisol was moderated by socioeconomic disadvantage. Biological response systems (immune and endocrine) were differentially associated with distinct forms of early-life adversities.

RESUMO

PURPOSE: To assess differences in baseline and longitudinal quality of life among Black and White individuals in the US with advanced prostate cancer. METHODS: Secondary analysis of data from the International Registry for Men with Advanced Prostate Cancer (IRONMAN) including US participants newly diagnosed with advanced prostate cancer and identifying their race as Black or White from 2017 to 2023. Participants completed the EORTC QLQ-C30 Quality of Life (QoL) Survey at study enrollment and every 3 months thereafter for up to 1 year of follow-up reporting 15 scale scores ranging from 0 to 100 (higher functioning and lower symptom scores represent better quality of life). Linear mixed effects models with race and month of questionnaire completion were fit for each scale, and model coefficients were used to assess differences in baseline and longitudinal QoL by race. RESULTS: Eight hundred and seventy-nine participants were included (20% identifying as Black) at 38 US sites. Compared to White participants at baseline, Black participants had worse constipation (mean 6.3 percentage points higher; 95% CI 2.9-9.8), financial insecurity (5.7 (1.4-10.0)), and pain (5.1 (0.9-9.3)). QoL decreased over time similarly by race; most notably, role functioning decreased by 0.7 percentage points (95% CI -0.8, -0.5) per month. CONCLUSION: There are notable differences in quality of life at new diagnosis of advanced prostate cancer for Black and White individuals, and quality of life declines similarly in the first year for both groups. Interventions that address specific aspects of quality of life in these patients could meaningfully improve the overall survivorship experience.

RESUMO

An understanding of child psychopathology and resilience requires attention to the nested and interconnected systems and contexts that shape children's experiences and health outcomes. In this study, we draw on data from the National Survey of Children's Health, 2016 to 2021 (n = 182,375 children, ages 3- to 17 years) to examine associations between community social capital and neighborhood resources and children's internalizing and externalizing problems, and whether these associations were moderated by experiences of racial discrimination. Study outcomes were caregiver-report of current internalizing and externalizing problems. Using logistic regression models adjusted for sociodemographic characteristics of the child and household, higher levels of community social capital were associated with a lower risk of children's depression, anxiety, and behaviors. Notably, we observed similar associations between neighborhood resources and child mental health for depression only. In models stratified by the child's experience of racial/ethnic discrimination, the protective benefits of community social capital were specific to those children who did not experience racial discrimination. Our results illustrate heterogeneous associations between community social capital and children's mental health that differ based on interpersonal experiences of racial/ethnic discrimination, illustrating the importance of a multilevel framework to promote child wellbeing.

RESUMO

BACKGROUND: Bereaved youth are at greater risk for adverse mental health outcomes, yet less is known about how social context shapes health for bereaved children. Ecosocial theory is employed to conceptualize bereavement in the context of sociodemographic factors. METHOD: This longitudinal study used data from the Avon Longitudinal Study of Parents and Children. Of the 15,454 pregnancies enrolled, 5050 youth were still enrolled at age 16.5 and completed self-report questionnaires on life events and emotional/behavioral symptoms. RESULTS: Sociodemographic precursors associated with parent, sibling, or close friend bereavement included maternal smoking, parental education levels, and financial difficulties. The significant yet small main effect of higher cognitive ability, assessed at age 8, on reduced emotional/behavioral symptoms at age 16.5 (ß = -0.01, SE = 0.00, p < 0.001) did not interact with bereavement. Bereavement of a parent, sibling, or close friend was associated with a 0.19 point higher emotional/behavioral symptom log score compared to non-bereaved youth (95% CI: 0.10-0.28), across emotional, conduct, and hyperactivity subscales. CONCLUSIONS: Descriptive findings suggest sociodemographic precursors are associated with bereavement. While there was an association between the bereavement of a parent, sibling, or close friend and elevated emotional/behavioral symptoms, cognitive ability did not moderate that effect.

RESUMO

BACKGROUND: Exposure to chronic psychological stress across multiple life domains (multi-domain chronic burden) is associated with poor health. This may be because multi-domain chronic burden influences daily-level emotional processes, though this hypothesis has not been thoroughly tested. PURPOSE: The current study tested whether (a) multi-domain chronic burden is associated with greater exposure to daily stressors and (b) multi-domain chronic burden compounds negative affect on days with stressors compared to stressor-free days. METHODS: The MIDUS Study (Wave II) and the National Study of Daily Experiences sub-study were conducted from 2004 to 2006 (N = 2,022). Participants reported on eight life domains of psychological stress used to create a multi-domain chronic burden summary score. For eight consecutive days, participants reported the daily occurrence of stressful events and daily negative affect. RESULTS: Participants with greater multi-domain chronic burden were significantly more likely to report daily stressors. There was also a significant interaction between multi-domain chronic burden and daily stressors on negative affect: participants with higher multi-domain chronic burden had greater negative affect on stressor days than stressor-free days compared to those with lower multi-domain chronic burden. CONCLUSION: Participants with higher multi-domain chronic burden were more likely to report daily stressors and there was a compounding effect of multi-domain chronic burden and daily stressors on negative affect. These results suggest that experiencing a greater amount of psychological stress across multiple life domains may make daily stressors more toxic for daily affect.

RESUMO

In ecology and evolutionary biology (EEB), the study of developmental plasticity seeks to understand ontogenetic processes underlying the phenotypes upon which natural selection acts. A central challenge to this inquiry is ascertaining a causal effect of the exposure on the manifestation of later-life phenotype due to the time elapsed between the two events. The exposure is a potential cause of the outcome-i.e. an environmental stimulus or experience. The later phenotype might be a behaviour, physiological condition, morphology or life-history trait. The latency period between the exposure and outcome complicates causal inference due to the inevitable occurrence of additional events that may affect the relationship of interest. Here, we describe six distinct but non-mutually exclusive conceptual models from the field of lifecourse epidemiology and discuss their applications to EEB research. The models include Critical Period with No Later Modifiers, Critical Period with Later Modifiers, Accumulation of Risk with Independent Risk Exposures, Accumulation of Risk with Risk Clustering, Accumulation of Risk with Chains of Risk and Accumulation of Risk with Trigger Effect. These models, which have been widely used to test causal hypotheses regarding the early origins of adult-onset disease in humans, are directly relevant to research on developmental plasticity in EEB.

RESUMO

In this egocentric network study, we explored Chinese collectivism in relation to social network characteristics and sex work-related stigma among mid-age female sex workers (FSWs). Respondent-driven sampling was used to recruit 1245 mid-age FSWs from three cities in China. We found that a one standard deviation (SD) increase in FSWs' collectivism was associated with a 0.18 SD decrease in social support (95% CI - 0.32, - 0.04), a 0.20 SD decrease in network effective size (i.e., the diversity of a social network; 95% CI - 0.30, - 0.10), and a 0.21 SD decrease in network betweenness (i.e., the "bridging potential" of egos within their networks; 95% CI - 0.33, - 0.09). Among participants who perceived more sex work stigma, the association between collectivism and FSWs' network betweenness was attenuated. In a collective culture emphasizing group values and honor, belonging to a less interconnected social network may give FSWs a structural advantage to cope with stigma and secure social support.

RESUMO

This report examines associations between everyday discrimination, microaggressions, and CRP to gain insight on potential mechanisms that may underlie increased CVD risk among sexual minority male young adults. The sample consisted of 60 participants taken from the P18 cohort between the ages of 24 and 28 years. Multinomial logistic regression models were used to examine the association between perceived everyday discrimination and LGBQ microaggressions with C-reactive protein cardiovascular risk categories of low-, average-, and high-risk, as defined by the American Heart Association and Centers for Disease Control. Adjustments were made for BMI. Individuals who experienced more everyday discrimination had a higher risk of being classified in the high-risk CRP group compared to the low-risk CRP group (RRR = 3.35, p = 0.02). Interpersonal LGBQ microaggressions were not associated with CRP risk category. Everyday discrimination, but not specific microaggressions based on sexual orientation, were associated with elevated levels of CRP among young sexual minority men (YSMM). Thus, to implement culturally and age-appropriate interventions, further researcher is needed to critically examine the specific types of discrimination and the resultant impact on YSMM's health.

RESUMO

Racial/ethnic discrimination may contribute to the risk of type 2 diabetes mellitus (T2DM), but few studies have prospectively examined this relationship among racially/ethnically diverse populations. We analyzed prospective data from 33,833 eligible Sister Study participants enrolled from 2003 to 2009. In a follow-up questionnaire (2008-2012), participants reported their lifetime experiences of everyday and major forms of racial/ethnic discrimination. Self-reported physician diagnoses of T2DM were ascertained through September 2017. Hazard ratios and 95% confidence intervals were estimated using Cox proportional hazards models, overall and by race/ethnicity. Mean age at enrollment was 54.9 (standard deviation, 8.8) years; 90% of participants self-identified as non-Hispanic (NH) White, 7% as NH Black, and 3% as Hispanic/Latina. Over an average of 7 years of follow-up, there were 1,167 incident cases of T2DM. NH Black women most frequently reported everyday (75%) and major (51%) racial/ethnic discrimination (vs. 4% and 2% of NH White women, respectively, and 32% and 16% of Hispanic/Latina women, respectively). While everyday discrimination was not associated with T2DM risk, experiencing major discrimination was marginally associated with higher T2DM risk overall (hazard ratio = 1.26, 95% confidence interval: 0.99, 1.61) after adjustment for sociodemographic characteristics and body mass index. Associations were similar across racial/ethnic groups; however, racial/ethnic discrimination was more frequently reported among racial/ethnic minority women. Antidiscrimination efforts may help mitigate racial/ethnic disparities in T2DM risk.

RESUMO

Vaginal microbiota provide the first line of defense against urogenital infections primarily through protective actions of Lactobacillus species Perceived stress increases susceptibility to infection through several mechanisms, including suppression of immune function. We investigated whether stress was associated with deleterious changes to vaginal bacterial composition in a subsample of 572 women in the Longitudinal Study of Vaginal Flora, sampled from 1999 through 2002. Using Cox proportional hazards models, both unadjusted and adjusted for sociodemographic factors and sexual behaviors, we found that participants who exhibited a 5-unit-increase in Cohen's Perceived Stress Scale had greater risk (adjusted hazard ratio (HR) = 1.40, 95% confidence interval (CI): 1.13, 1.74) of developing molecular bacterial vaginosis (BV), a state with low Lactobacillus abundance and diverse anaerobic bacteria. A 5-unit increase in stress score was also associated with greater risks of transitioning from the L. iners-dominated community state type (26% higher) to molecular-BV (adjusted HR = 1.26, 95% CI: 1.01, 1.56) or maintaining molecular-BV from baseline (adjusted HR = 1.23, 95% CI: 1.01, 1.47). Inversely, women with baseline molecular-BV reporting a 5-unit stress increase were less likely to transition to microbiota dominated by L. crispatus, L. gasseri, or L. jensenii (adjusted HR = 0.81, 95% CI: 0.68, 0.99). These findings suggest that psychosocial stress is associated with vaginal microbiota composition, inviting a more mechanistic exploration of the relationship between psychosocial stress and molecular-BV.

RESUMO

Inequalities in health outcomes impose substantial human and economic costs on all societies-and the relation between early adversity and lifelong well-being presents a rich scientific framework for fresh thinking about health promotion and disease prevention broadly, augmented by a deeper focus on how racism influences disparities more specifically. This review begins with an overview of advances in the biology of adversity and resilience through an early childhood lens, followed by an overview of the unique effects of racism on health and a selective review of findings from related intervention research. This article presents a framework for addressing multiple dimensions of the public health challenge-including institutional/structural racism, cultural racism, and interpersonal discrimination-and concludes with the compelling need to protect the developing brain and other biological systems from the physiological disruptions of toxic stress that can undermine the building blocks of optimal health and development in the early childhood period.
