Relationships between allostatic load, unhealthy behaviors, and depressive disorder in U.S. adults, 2005-2012 NHANES

Examining the Qualitative Experiences of Latinx Nurses During the First Wave of COVID-19

Introduction: The world has been impacted by the coronavirus disease 2019 (COVID-19) pandemic since March of 2020. Latinx nurses have been some of the most underrepresented in being studied during this time and have been greatly affected by it. To the best of our knowledge, there are no published studies that focus on the qualitative experiences of Latinx nurses during the first wave of the pandemic. Methods: Data analysis included thematic analysis to identify main themes experienced by Latinx nurses. A qualitative descriptive study design was employed to conduct a parent study with 100 nurses across the United States reflecting on their experiences during the first wave of the COVID-19 pandemic, data collected from May to September 2020. Formal coding of the interview data was conducted utilizing Dedoose cloud-based software. Results: Five main themes emerged, including (1) connection to patients' personal touch and empathy, (2) connection to Latinx nurses, (3) connection to family and friends, (4) connection to food as care, and (5) coping. Within the theme of coping, subthemes of (5.1) faith, (5.2) maladaptive behaviors, and (5.3) self-care activities emerged. Conclusion: These experiences can help shape the pathway to be better prepared for any emergency or future pandemic.

Depression, Sleep Health & Sociodemographic Correlates in a Nationwide Survey: Implications for Depression Treatment During the COVID-19

Purpose

The COVID-19 pandemic has had a profound impact on mental health worldwide, with depression and sleep problems among the most common issues experienced by many individuals. Depression can lead to sleep problems, which can increase the risk of developing depressive symptoms. However, it is unclear which United States (US) sub-population was most affected by depression and sleep problems during the pandemic.

Methods

We conducted a secondary analysis using self-reported data from the 2021 National Health Interview Survey (NHIS), focusing on adults aged 18 years and above (n=29,763). We utilized self-reported responses to questions about prescription medication and frequency of depressive feelings to determine participants' depression status. Appropriate weights were applied to account for the sampling design of the surveys. Our analysis involved descriptive statistics and chi-squared tests to compare sociodemographic, clinical, behavioral, and sleep-related characteristics between US adults with and without depression. Additionally, logistic regression was used to examine the associations between sleep duration, sleep quality and depression.

Results

The overall prevalence of depression in our sample was 44.4%. It were higher in certain demographic groups, including younger adults (18-39 years, 47.7%), non-Hispanic whites (47.9%), females (50.1%), those at the lower income bracket (52.2%), those with no college or degree (48.7%) uninsured individuals (45.2%), and those reporting poor general health (71.9%). Individuals with depression had a 12% increased odds of experiencing short sleep (aOR: 1.12, 95% CI:1.04-1.20, p<0.001), 34% increased odds of experiencing long sleep (aOR: 1.34, 95% CI: 1.20-1.50, p < 0.001) and more than 2.5 fold increased odds of reporting poor sleep quality (aOR:2.57, 95% CI: 2.40-2.78; p<0.0001). In the multivariate analysis, all variables (sex, race/ethnicity, education, health insurance coverage, marital status, general health status and use of sleep medications, smoking and alcohol use status) were significantly predictors of poor sleep quality, with the exceptions of age and family income.

Conclusion

The findings emphasize the need to address sleep health in treating depression, especially during times of public health crises.

Comprehensive allostatic load risk index is associated with increased frontal and left parietal white matter hyperintensities in mid-life cognitively healthy adults

To date, there is a considerable heterogeneity of methods to score Allostatic Load (AL). Here we propose a comprehensive algorithm (ALCS) that integrates commonly used approaches to generate AL risk categories and assess associations to brain structure deterioration. In a cohort of cognitively normal mid-life adults (n = 620, age 51.3 ± 5.48 years), we developed a comprehensive composite for AL scoring incorporating gender and age differences, high quartile approach, clinical reference values, and current medications, to then generate AL risk categories. Compared to the empirical approach (ALES), ALCS showed better model fit criteria and a strong association with age and sex. ALSC categories were regressed against brain and white matter hyperintensity (WMH) volumes. Higher AL risk categories were associated with increased total, periventricular, frontal, and left parietal WMH volumes, also showing better fit compared to ALES. When cardiovascular biomarkers were removed from the ALSC algorithm, only left-frontal WMHV remained associated with AL, revealing a strong vascular burden influencing the index. Our results agree with previous evidence and suggest that sustained stress exposure enhances brain deterioration in mid-life adults. Showing better fit than ALES, our comprehensive algorithm can provide a more accurate AL estimation to explore how stress exposure enhances age-related health decline.

Racial-ethnic disparities in psychological distress during the COVID-19 pandemic in the United States: the role of experienced discrimination and perceived racial bias

BACKGROUND

Research on mental health disparities by race-ethnicity in the United States (US) during COVID-19 is limited and has generated mixed results. Few studies have included Asian Americans as a whole or by subgroups in the analysis.

METHODS

Data came from the 2020 Health, Ethnicity, and Pandemic Study, based on a nationally representative sample of 2,709 community-dwelling adults in the US with minorities oversampled. The outcome was psychological distress. The exposure variable was race-ethnicity, including four major racial-ethnic groups and several Asian ethnic subgroups in the US. The mediators included experienced discrimination and perceived racial bias toward one's racial-ethnic group. Weighted linear regressions and mediation analyses were performed.

RESULTS

Among the four major racial-ethnic groups, Hispanics (22%) had the highest prevalence of severe distress, followed by Asians (18%) and Blacks (16%), with Whites (14%) having the lowest prevalence. Hispanics' poorer mental health was largely due to their socioeconomic disadvantages. Within Asians, Southeast Asians (29%), Koreans (27%), and South Asians (22%) exhibited the highest prevalence of severe distress. Their worse mental health was mainly mediated by experienced discrimination and perceived racial bias.

CONCLUSIONS

Purposefully tackling racial prejudice and discrimination is necessary to alleviate the disproportionate psychological distress burden in racial-ethnic minority groups.

Allostatic load and depressive symptoms in older adults: An analysis of 12-year panel data

BACKGROUND

Whether changes in allostatic load (AL) and depressive symptoms relate over time has not been yet fully explored. This study evaluated the association between AL and depressive symptoms over 12 years among community-dwelling older adults.

METHODS

Panel data from 8291 participants in the English Longitudinal Study of Ageing were analysed. Depressive symptoms were assessed with the 8-item Centre for Epidemiologic Studies Depression Scale (CES-D). The AL score was derived from nine metabolic, cardiovascular and immune biomarkers. The association between AL and depressive symptoms was modelled in a linear hybrid model adjusting for time-invariant (sex, ethnicity) and time-variant confounders (age, marital status, education, wealth, physical activity, smoking status, alcohol intake, limitations in daily living, comorbidities).

RESULTS

The mean AL score was 3.1 (SD: 2.1), 3.5 (2.3), 3.2 (2.3) and 3.3 (2.5) whereas the mean CES-D score was 1.4 (SD: 1.8), 1.2 (1.8), 1.2 (1.8) and 1.2 (1.7) in waves 2, 4, 6 and 8, respectively. In the adjusted model, the between-person differences (coefficient: 0.02, 95% CI: 0.01, 0.04) but not the within-individual differences (0.01; 95% CI: -0.01, 0.03) in the AL score were associated with CES-D score. The between-person coefficient indicates that participants with greater AL scores also had slightly higher CES-D scores. The within-person coefficient indicates that changes in the AL score were not associated with changes in the CES-D score.

CONCLUSION

AL was associated with depressive symptoms. However, most of the association was driven by differences in AL between individuals rather than changes in AL over time.

The Association of Combined Per- and Polyfluoroalkyl Substances and Metals with Allostatic Load Using Bayesian Kernel Machine Regression

Background/Objective: This study aimed to investigate the effect of exposure to per- and polyfluoroalkyl substances (PFAS), a class of organic compounds utilized in commercial and industrial applications, on allostatic load (AL), a measure of chronic stress. PFAS, such as perfluorodecanoic acid (PFDE), perfluorononanoic acid (PFNA), perfluorooctane sulfonic acid (PFOS), perfluoroundecanoic acid (PFUA), perfluorooctanoic acid (PFOA), and perfluorohexane sulfonic acid (PFHS), and metals, such as mercury (Hg), barium (Ba), cadmium (Cd), cobalt (Co), cesium (Cs), molybdenum (Mo), lead (Pb), antimony (Sb), thallium (TI), tungsten (W), and uranium (U) were investigated. This research was performed to explore the effects of combined exposure to PFAS and metals on AL, which may be a disease mediator. Methods: Data from the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2014 were used to conduct this study on persons aged 20 years and older. A cumulative index of 10 biomarkers from the cardiovascular, inflammatory, and metabolic systems was used to calculate AL out of 10. If the overall index was ≥ 3, an individual was considered to be chronically stressed (in a state of AL). In order to assess the dose-response connections between mixtures and outcomes and to limit the effects of multicollinearity and other potential interaction effects between exposures, Bayesian kernel machine regression (BKMR) was used. Results: The most significant positive trend between mixed PFAS and metal exposure and AL was revealed by combined exposure to cesium, molybdenum, PFHS, PFNA, and mercury (posterior inclusion probabilities, PIP = 1, 1, 0.854, 0.824, and 0.807, respectively). Conclusions: Combined exposure to metals and PFAS increases the likelihood of being in a state of AL.

Allostatic Load and Depression Symptoms in Cancer Survivors: A National Health and Nutrition Examination Survey Study

BACKGROUND

Individuals with cancer often experience stress throughout the cancer trajectory and have a high risk of experiencing depression.

OBJECTIVE

The aim of this study was to examine the relationship between allostatic load (AL), a measure of cumulative stress-related physiologic dysregulation of different body systems, and symptoms of depression in cancer survivors.

METHODS

Participants were 294 adult cancer survivors from the US National Health and Nutrition Examination Survey (NHANES 2007-2018). Allostatic load was measured using 14 indicators representing cardiometabolic risk, glucose metabolism, cardiopulmonary functioning, parasympathetic functioning, and inflammation. Depressive symptoms were measured with the Patient Health Questionnaire-9. The relationship between AL and depressive symptoms was investigated using multiple regression adjusted for diverse sociodemographic and diagnosis variables.

RESULTS

Higher AL was associated with higher depressive symptom scores. The higher risk of depression was concentrated among those survivors in the highest AL quartile, with 21% (95% confidence interval, 11%-32%) of survivors presenting a high risk of depression compared with 8% to 11% of survivors in the lower quartiles. In exploratory analyses, the relationship between AL and depressive symptoms was only significant among survivors with a lower income. In contrast, in survivors in the highest income group, depressive symptoms were lower and unrelated to AL.

CONCLUSION

High AL is associated with more depressive symptoms among cancer survivors.

IMPLICATIONS FOR PRACTICE

Nurses have an important role in identifying psychological distress in cancer patients and survivors. Further research is needed to investigate the usefulness of AL as a marker in the context of cancer follow-up care and screening for psychological distress.

"Now I just need something sweet": Racism, emotional eating, and health among African Americans

BACKGROUND

The Environmental Affordances Model theorizes that systemic racism disproportionately exposes African Americans in the United States to chronic everyday stressors (e.g., individual racism) while simultaneously shaping the availability of coping resources (e.g., fast food outlets) and engagement in self-regulatory strategies (e.g., emotional eating). Greater engagement in self-regulatory strategies is theorized to preserve mental health while contributing to medical morbidities and mortality.

OBJECTIVE

However, few studies have tested the Environmental Affordances Model, limiting our understanding of how the proposed pathways operate in the lives of African Americans.

METHODS

In the present study, the associations between systemic racism (institutional racism, cultural racism, neighborhood disadvantage), chronic everyday stressors (exposure to individual racism), emotional eating, and mental (anxiety symptomatology) and physical (self-rated overall physical health) health are assessed in a sample of 751 African Americans aged 18 to 88.

RESULTS

The path analysis reveals that institutional and cultural racism are both positively associated with individual racism. Neighborhood disadvantage is inversely associated with individual racism. Individual racism is significantly associated with greater anxiety symptomatology but is unrelated to self-rated overall physical health. Institutional and cultural racism are associated with emotional eating although individual racism and neighborhood disadvantage are not. Moreover, engagement in emotional eating exacerbates, rather than mitigates, the impacts of individual racism on anxiety symptomatology.

CONCLUSIONS

We conclude that institutional and cultural racism contribute to individual racism experiences and emotional eating whereas emotional eating exacerbates associations among individual racism and anxiety symptomatology.

Allostatic Load Measurement: A Systematic Review of Reviews, Database Inventory, and Considerations for Neighborhood Research

BACKGROUND

Neighborhoods are critical to understanding how environments influence health outcomes. Prolonged environmental stressors, such as a lack of green spaces and neighborhood socioeconomic disadvantage, have been associated with higher allostatic load levels. Since allostatic load levels experienced earlier in life have stronger associations with mortality risk, neighborhoods may be uniquely suited to monitor and mitigate the impacts of environmental stressors. Researchers often study allostatic load in neighborhoods by utilizing administrative boundaries within publicly accessible databases as proxies for neighborhoods.

METHODS

This systematic review of reviews aims to identify commonly used biomarkers in the measurement of allostatic load, compare measurement approaches, inventory databases to study allostatic load, and spotlight considerations referenced in the literature where allostatic load is studied in neighborhoods. The review was conducted using the search term "allostatic load" in the MEDLINE, CINAHL, and PsychINFO databases. The search results were filtered to include reviews.

RESULTS

The search returned 499 articles after deduplication. Overall, 18 synthesis reviews met the inclusion criteria and were retained for extraction. The synthesis reviews analyzed represented 238 studies published from 1995 to 2020. The original ten biomarkers were most often used to measure allostatic load. More recently, body mass index and C-reactive protein have additionally been frequently used to measure allostatic load burden.

CONCLUSIONS

The scientific contributions of this study are that we have identified a clear gap in geographic considerations when studying allostatic load. The implication of this study is that we have highlighted geographic concepts when conducting neighborhood-level research using administrative databases as a neighborhood proxy and outlined emerging future trends that can enable future study of allostatic load in the neighborhood context.

Approaching Mental Health Equity in Neuroscience for Black Women Across the Lifespan: Biological Embedding of Racism From Black Feminist Conceptual Frameworks

Black women in the United States are faced with unrelenting chronic stressors that are often driven by racism and oppression and that result in mental health inequities. Similar to common U.S. societal views of Black women, ideological values about Black women's lives also permeate psychiatry and neuroscience research to prevent likely impactful research that fully examines the role of social power structures in the biological embedding of racism. This article's overall aim is to highlight the most urgent areas to address in mental health inequities utilizing a Black feminist lens that include 1) culturally grounded and contextually relevant considerations for the biological embedding of racism on mental health outcomes for Black women across the lifespan and 2) intersectional frameworks that address mental health inequities ingrained in multiple marginalization. We conclude with a call to action informed by Black feminist thought for the field of neuroscience to make a concerted effort to address mental health inequities among Black women and other disenfranchised groups from a frame of compassion, cultural humility, and a continuous pursuit of social justice.

Bearing allostatic load: insights into a more equitable future within cardio-oncology

Chronic stress is often regarded as a significant cause of morbidity and mortality; however, the mechanistic link between stress and various disease states has not yet been fully characterized. We explore the concept of allostatic load, a measurement of the physiological burden of chronic stress, as well as its potential role in disease pathogenesis as it relates to cardiovascular disease, cancer, and health-related disparities. Building from this framework, we then posit the potential implications of allostatic load on patient care and research in cardio-oncology. We identify allostatic load as a potential clinically actionable tool to improve health equity in cardio-oncology.

Shades of Black: Gendered Denominational Variation in Depression Symptoms Among Black Christians

Religion and spirituality (R/S) play a central role in shaping the contextual experiences of many Black people in the United States. Blacks are among the most religiously engaged groups in the country. Levels and types of religious engagement, however, can vary by subcategories such as gender or denominational affiliation. Although R/S involvement has been linked to improved mental health outcomes for Black people in general, it is unclear whether these benefits extend to all Black people who claim R/S affiliation irrespective of denomination and gender. Data from the National Survey of American Life (NSAL) sought to determine whether there are differences in the odds of reporting elevated depressive symptomology among African American and Black Caribbean Christian adults across denominational affiliation and gender. Initial logistic regression analysis found similar odds of elevated depressive symptoms across gender and denominational affiliation, but further analysis revealed the presence of a denomination by gender interaction. Specifically, there was a significantly larger gender gap in the odds of reporting elevated depression symptoms for Methodists than for Baptists and Catholics. In addition, Presbyterian women had lower odds of reporting elevated symptoms than Methodist women. This study's findings highlight the importance of examining denominational disparities among Black Christians, and suggest that denomination and gender may work in tandem to shape the R/S experiences and mental health outcomes of Black people in the United States.

Hearing loss and risk of depressive symptoms in older adults in the Health ABC study

Objective

Hearing loss (HL) is highly prevalent among older adults and may lead to increased risk of depressive symptoms. In both cross-sectional and longitudinal analysis, we quantified the association between HL and depressive symptoms, incorporating the variable nature of depressive symptoms and characterizing by race and gender.

Methods

Data were from the Health, Aging, and Body Composition study. Depressive symptoms were measured using the Center for Epidemiologic Study Depression Scale short form (CES-D 10), defined as CES-D 10 score ≥10 or treatment for depression. Hearing was defined via four-frequency pure-tone average (PTA) decibel hearing level (dB HL), categorized as normal hearing (PTA ≤25 dB HL), mild HL (PTA26-40 dB HL), and ≥moderate HL (PTA > 40 dB HL). Associations at baseline were quantified using logistic regression, incident depressive symptoms using Cox proportional hazard models, and change in depressive symptoms over time using growth mixture models and multinomial logistic regression.

Results

Among 2,089 older adults (1,082 women, 793 Black; mean age 74.0 SD: 2.8), moderate or greater HL was associated with greater odds of concurrent [Odds Ratio (OR):2.45, 95% CI:1.33, 4.51] and incident depressive symptoms [Hazard Ratio (HR):1.26, 95% CI:1.00, 1.58]. Three depressive symptom trajectory patterns were identified from growth mixture models: low, moderate increasing, and borderline high depressive symptom levels. Those with moderate or greater HL were more likely to be in the borderline high depressive-symptom trajectory class than the low trajectory class [Relative Risk Ratio (RRR):1.16, 95% CI:1.01, 1.32].

Conclusions

HL was associated with greater depressive symptoms. Although findings were not statistically significantly different by gender and race, estimates were generally stronger for women and Black participants. Investigation of psychosocial factors and amelioration by hearing aid use could have significant benefit for older adults' quality of life.

Depressive symptoms and allostatic load have a bidirectional association among Puerto Rican older adults

BACKGROUND

Depression is strongly associated with chronic disease; yet, the direction of this relationship is poorly understood. Allostatic load (AL) provides a framework for elucidating depression-disease pathways. We aimed to investigate bidirectional, longitudinal associations of baseline depressive symptoms or AL with 5-year AL or depressive symptoms, respectively.

METHODS

Data were from baseline, 2-year, and 5-year visits of 620 adults (45-75 years) enrolled in the Boston Puerto Rican Health Study. The Center for Epidemiology Studies Depression (CES-D) scale (0-60) captured depressive symptoms, which were categorized at baseline as low (<8), subthreshold (8-15), or depression-likely (⩾16) symptoms. AL was calculated from 11 parameters of biological functioning, representing five physiological systems. Baseline AL scores were categorized by the number of dysregulated parameters: low (0-2), moderate (3-5), or high (⩾6) AL. Multivariable, multilevel random intercept and slope linear regression models were used to examine associations between 3-category baseline CES-D score and 5-year continuous AL score, and between baseline 3-category AL and 5-year continuous CES-D score.

RESULTS

Baseline subthreshold depressive symptoms [(mean (95% CI)): 4.8 (4.5-5.2)], but not depression-likely symptoms [4.5 (4.2-4.9)], was significantly associated with higher 5-year AL scores, compared to low depressive symptoms [4.3 (3.9-4.7)]. Baseline high AL [19.4 (17.6-21.2)], but not low AL [18.5 (16.5-20.6)], was significantly associated with higher 5-year CES-D score, compared to baseline moderate AL [16.9 (15.3-18.5)].

CONCLUSIONS

Depressive symptoms and AL had a bi-directional relationship over time, indicating a nuanced pathway linking depression with chronic diseases among a minority population.

Adverse childhood experiences and allostatic load: A systematic review

Adverse Childhood Experiences (ACEs) are stressful and/or traumatic experiences associated with an increased lifetime risk of negative health outcomes. The Allostatic Load (AL) is a measure of multisystem dysregulation, resulted by chronic stress. We systematically reviewed the English language literature on the association between ACEs and AL to identify the clinical risk profile, with the exclusion of reviews and preclinical studies. Searches covered the publication period up to the 1^st of February 2022 and identified 25 studies in which ACEs such as maltreatment, abuse, poverty, psychological abuse, and discrimination were investigated in the context of AL. The selected studies used different sets of AL biomarkers resulting in substantial heterogenicity of calculating the AL index. Overall, we found that ACEs are associated with elevated AL and poorer health outcomes in adulthood. Furthermore, health risk behaviors, social support, and coping resources either moderate or mediate this association. These findings suggest that targeting individuals at risk and starting interventions early might reduce AL and its deleterious health consequences.

The Association between Multiple Per- and Polyfluoroalkyl Substances' Serum Levels and Allostatic Load

Background/Objective: This study aimed to explore the association between allostatic load (AL), an index of chronic stress, with nine per- and polyfluoroalkyl substances (PFASs), a group of organic compounds used in commercial and industrial applications. The PFASs explored were perfluorohexane sulfonic acid (PFHS), perfluorodecanoic acid (PFDE), perfluorobutane sulfonic acid (PFBS), perfluoroheptanoic acid (PFHP), perflurododecanoic acid (PFDO), perfluorononanoic acid (PFNA), perfluoroundecanoic acid (PFUA), perfluorooctanoic acid (PFOA), and perfluorooctane sulfonic acid (PFOS). This study was performed to better understand the association between PFASs and AL, which may be a mediator of several diseases. Methods: This study was performed on adults aged 20 and older, using the National Health and Nutrition Examination Survey (NHANES) 2007−2014 data. AL was calculated as a cumulative index of ten biomarkers from the cardiovascular, inflammatory, and metabolic system, which was dichotomized into high risk (assigned a value of 1) or low risk (assigned a value 0) depending on if the index value was ≥3 (chronic physiological stress) or <3 (less stressed). In this study, PFASs and covariates such as age, gender, ethnicity, alcohol consumption, smoking, and physical activity were explored using descriptive statistics and logistic regression modeling. Results: The results indicated that in adults, AL was more elevated in men as compared to women, in those aged ≥60 years, and varied by ethnicity. For instance, non-Hispanic Blacks had higher AL levels (mean of 3.92) compared to other ethnicities. A significant number of the participants tested for PFBS, PFHP, PFDO were below the LOD and thus these PFASs were excluded from the analysis. Our analysis demonstrated multicollinearities between variables such as PFNA, PFOS, and PFOA with variance inflation factor (VIF) values of 6.197, 6.212, and 5.139, respectively. Thus, PFASs were analyzed individually and adjusted for age, gender, ethnicity, physical activity, smoking, and alcohol consumption. The results indicated a statistically significant positive association between AL and most of the PFASs, except PFUA which was not statistically significant with a p value of 0.531. Conclusions: The findings of this study suggest that exposure to PFDE, PFNA, PFOS, PFOA, and PFHS are associated with AL when adjusted for age, gender, ethnicity, alcohol consumption, smoking, and physical activity. Future studies looking to model the effects of these factors together must consider their relationship with each other and choose different analytical approaches.

Clusters of COVID-19 protective and risky behaviors and their associations with pandemic, socio-demographic, and mental health factors in the United States

•

Protective and risky behaviors for COVID-19 cluster in a U.S.-based sample.

•

Behavior classes had differing patterns of socio-demographics and pandemic exposure.

•

Posttraumatic stress and anxiety were elevated among protective and risky classes.

Individual behaviors are critical for preventing the spread of coronavirus disease 2019 (COVID-19) infection. Given that both protective and risky behaviors influence risk of infection, it is critical that we understand how such behaviors cluster together and in whom. Using a data-driven approach, we identified clusters of COVID-19-related protective and risky behaviors and examined associations with socio-demographic, pandemic, and mental health factors. Data came from a cross-sectional online U.S. nationwide study of 832 adults with high levels of pre-pandemic trauma. Latent class analysis was performed with ten protective (e.g., washing hands, wearing masks) and eight risky (e.g., attending indoor restaurants, taking a flight) behaviors for COVID-19. Then, we examined distributions of socio-demographic and pandemic factors across behavior classes using ANOVA or Chi-square tests, and associations between mental health factors (depressive, anxiety, posttraumatic stress symptoms) and behavior classes using multinomial logistic regression. We identified four classes, including three classes with relatively low risky but high (28.8%), moderate (33.5%) and minimal (25.5%) protective behaviors and one high risky behaviors class with associated moderate protective behaviors (12.1%). Age, sexual orientation, political preference, and most pandemic factors differed significantly across behavior classes. Anxiety and posttraumatic stress symptoms, but not depression, were higher in the High Risk, but also Highly and Moderately Protective classes, relative to Minimally Protective. Prevention and intervention efforts should examine constellations of protective and risky behaviors to comprehensively understand risk, and consider current anxiety and posttraumatic stress symptoms as potential risk indicators.

Allostatic Load, Single, and Dual Chronic Conditions: Evidence from the National Health and Nutrition Examination Survey

Background:

Allostatic load (AL) is defined as a cumulative burden of chronic stress and life events, which involves the interaction of different physiological systems at varying degrees of activity. AL is suspected of contributing to health disparities among different populations. Suppressed or overactive physiological systems can interrupt AL affecting proper tissue and organ function leading to disease. The objective of our study was to determine the association of AL with dual chronic conditions.

Methods:

We used data from the National Health and Nutrition Examination Survey (NHANES). For the current analysis, we used the data cycles of 2007–2010, which is the most recent data that collected comprehensive measures of the composite AL outcome variable. Descriptive, bivariate, and multivariable logistic regression, with stepwise forward variable selection method (P < 0.05), were conducted using STATA/IC 15.0.

Results:

AL levels were high among 20% of the respondents (n = 2179). Having a lower income to poverty ratio, being married, physical inactivity, experiencing sleep problems, and a history of smoking were significantly associated with high AL (P < 0.05). Non-Hispanic blacks [odds ratio (OR): 1.8; 95% confidence interval (CI): 1.6–2.4] and Mexicans and other Hispanics (OR: 1.4; 95% CI: 1.1–1.7) had higher AL compared to Caucasians. Having cardiovascular disease (CVD) (OR: 1.7; 95% CI: 1.4–2.2) and diabetes (OR: 4.7; 95% CI: 3.8–5.7) independently, as well as both CVD and diabetes (OR: 3.1; 95% CI 2.7–3.6), were associated with higher odds of AL. We conducted an age-adjusted regression model that indicated higher odds of elevated AL among females with diabetes independently (OR: 1.4; 95% CI: 1.2–1.9) and with both CVD and diabetes (OR: 1.6; 95% CI: 1.2–2.1) compared to men.

Conclusions:

Despite the significant impact and association of AL with overall health, there is minimal evidence of its risk factors and linkage to disease burden. Modifiable lifestyle factors were associated with a higher AL. There is a critical need to support ethnic and gender contextual interventions to reduce the burden of AL on chronic conditions.

Financial Barriers to Mental Healthcare Services and Depressive Symptoms among Residents of Washington Heights, New York City

Objectives: In the United States, Hispanics are more likely to experience financial barriers to mental health care than non-Hispanics. We used a unique survey to study the effect of these financial barriers on the severity of depressive symptoms among Hispanics who had previously been diagnosed as having depression. Methods: This cross-sectional study used data from the 2015 Washington Heights Community Survey, administered to 2,489 households in Manhattan, New York City. Multiple regression models and propensity score matching were used to estimate the association between financial barriers to mental health care and depressive symptoms and the likelihood of being clinically depressed. Results: Among those diagnosed with depression, those with financial barriers to mental health services or counseling had significantly higher (β = 0.36, 95% CI = 0.03, 0.70) depressive symptoms. When propensity score matching was utilized, those with financial barriers to mental health services had significantly greater depressive symptoms (β = 0.63, 95% CI = 0.37, 0.89) and were significantly more likely to be currently depressed (OR = 2.38, 95% CI = 1.46, 3.89), in comparison to those who had access. Conclusions: Making mental health care more affordable and therefore more accessible to Hispanics is one step toward mitigating the burden on mental illness and decreasing health disparities.

Sulfur mustard and biological ageing: A multisystem biological health score approach as an extension of the allostatic load in Sardasht chemical veterans

BACKGROUND

Mustard gas as a chemical weapon has been used in wars and its long-term side effects are substantial in the human body. This study was aimed to apply an extension of allostatic load, known as synthetic biological health score (BHS), including the wear-and-tear of four physiological systems (endocrine, inflammatory, cardiovascular and metabolic systems) and two organs (liver and kidney) to estimate biological aging caused by sulfur mustard (SM) gas poisoning.

METHODS

The plasma samples were prepared from two following groups of people; 1) 446 individuals exposed to SM gas in 1987. 2) 115 healthy members, at the same range of age and residence, as the non-exposed group. These people were chosen from the same patients' families and have not had any exposure to SM or pulmonary dysfunction. To estimate BHS, 18 blood-derived biomarkers of the mentioned systems and organs were measured and the relative contribution of many social and body parameters across the age groups was explored.

RESULTS

It was revealed, in BHS calculation, the cardiovascular system had the most effect. Also, in the SM group, BHS was significantly higher than in the control group. This feature has a positive correlation with physical parameter (BMI) and a negative correlation with social parameters (salary and educational levels).

CONCLUSION

The multisystem BHS could be useful in the evaluation of biological aging due to SM exposure. Social (education, good-paying job) and physical (BMI) parameters could influence BHS and the higher BHS indicates the progress of biological aging due to mustard gas.

A Public Health Framework for Preventing Mental Disorders in the Context of Pandemics

The COVID-19 pandemic has universally threatened the building blocks of mental health, well-being, and quality of life, namely, expectations of safety, connectedness, hope, and individual and societal efficacy. Consequently, unprecedently large numbers of individuals are significantly stressed and many are at risk for relapse of mental health problems, exacerbations of existing mental and behavioral health problems, and new onset clinical problems. Because of the scope of the problem, a population-based public health perspective is needed, which in the context of disasters has well-established theories and prevention approaches. Public health approaches to disasters and pandemics focus on preventing subclinical problems from becoming clinical disorders, in comparison to clinical care approaches that focus on treating established disorders. Fortunately, specialty care clinicians who typically think about assessing and treating established disorders have the training and clinical competencies to deliver prevention-focused interventions. This paper is designed to help specialty care clinicians who use cognitive-behavioral strategies to understand the biopsychosocial impacts and resource deficits associated with COVID-19-related stressors and the public health perspective to address them. We also provide ways clinicians can help people who are suffering from significant stress and resource deficits bounce back and regain functioning. We describe psychological first aid, stress management, repeated ecological assessment, writing about stressors, problem-solving, and behavioral activation approaches to assist individuals at risk for enduring stress-linked problems.

Allostatic Load and Its Impact on Health: A Systematic Review

INTRODUCTION

Allostatic load refers to the cumulative burden of chronic stress and life events. It involves the interaction of different physiological systems at varying degrees of activity. When environmental challenges exceed the individual ability to cope, then allostatic overload ensues. Allostatic load is identified by the use of biomarkers and clinical criteria.

OBJECTIVE

To summarize the current knowledge on allostatic load and overload and its clinical implications based on a systematic review of the literature.

METHODS

PubMed, PsycINFO, Web of Science, and the Cochrane Library were searched from inception to December 2019. A manual search of the literature was also performed, and reference lists of the retrieved articles were examined.We considered only studies in which allostatic load or overload were adequately described and assessed in either clinical or non-clinical adult populations.

RESULTS

A total of 267 original investigations were included. They encompassed general population studies, as well as clinical studies on consequences of allostatic load/overload on both physical and mental health across a variety of settings.

CONCLUSIONS

The findings indicate that allostatic load and overload are associated with poorer health outcomes. Assessment of allostatic load provides support to the understanding of psychosocial determinants of health and lifestyle medicine. An integrated approach that includes both biological markers and clinimetric criteria is recommended.

Allostatic load, unhealthy behaviors, and depressive symptoms in the Hispanic Community Health Study/Study of Latinos

BACKGROUND

The Environmental Affordances Model (EAM) proposes that the effects of chronic stress on depression are moderated by unhealthy behaviors and race/ethnicity. The unique social structures and contexts of Hispanics/Latinos in the U.S. may influence such relationships. This study evaluated whether unhealthy behaviors weakened the relationship between allostatic load, a measure of chronic stress, and future elevated depressive symptoms among Hispanic Community Health Study/Study of Latinos participants.

METHODS

Longitudinal data (2008-2011 and 2014-2017) from 11,623 participants were analyzed. The exposure was allostatic load, an index of twelve established biomarkers categorized using clinically relevant cut points, at Visit 1. Elevated depressive symptoms were operationalized as a score of ≥10 (out of 30) on the CES-D 10 at Visit 2. An index of unhealthy behaviors, with one point each for cigarette smoking, excessive/binge drinking, sedentary behavior, and poor diet quality at Visit 1, was examined as an effect modifier. Multivariable logistic regression, in the overall sample and among Mexicans specifically and adjusted for demographic characteristics and elevated depressive symptoms at Visit 1, was used to model allostatic load, unhealthy behavior index (range: 0-4), and their interaction in relation to elevated depressive symptoms at Visit 2.

RESULTS

Overall, greater allostatic load was associated with higher odds of elevated depressive symptoms after at least 6 years (aOR = 1.06, 95% CI = 1.01, 1.10). Overall, individuals with greater allostatic load and an unhealthy behavior index = 1, compared to those with an unhealthy behavior index = 0, had lower odds of elevated depressive symptoms at follow-up (aβ = -0.065, 95% CI = -0.12, -0.007).

CONCLUSIONS

The relationship between chronic stress and depression was partially moderated among Hispanics/Latinos who engaged in unhealthy behavior, which may have reduced their risk of elevated depressive symptoms given more chronic stress.

Temporal trends in smoking and nicotine dependence in relation to co-occurring substance use in the United States, 2005-2016

BACKGROUND

Despite an overall decline in tobacco use in the United States, secular trends of smoking and nicotine dependence with co-occurring substance use are not well characterized.

METHODS

We examined self-reported tobacco and other substance use in 22,245 participants age 21-59 in the United States from six waves of the National Health and Nutrition Examination Survey (NHANES). Using Joinpoint regression, we assessed secular trends of smoking and nicotine dependence as a function of co-occurring use of alcohol, prescription opioids, marijuana/hashish, cocaine/heroin/methamphetamine, or other injection drug use. Multivariable logistic regressions were fitted to identify the potential risk factors.

RESULTS

During 2005-2016, the prevalence of current smoking decreased (without co-occurring substance use: 17.0 %-12.7 %; with co-occurring use of one substance: 35.3 % to 24.6 %; with co-occurring use of two or more substances: 53.8 %-42.2 %), and moderate-to-severe nicotine dependence decreased as well (8.0 %-4.2 %, 16.0 %-8.8 %, and 23.9 %-15.7 %, respectively). Smoking and nicotine dependence were more likely in those with co-occurring use of one substance (current smoking: odds ratio [OR] = 2.22, 95 % confidence interval [CI] = 2.01-2.45); nicotine dependence: OR = 1.88, 95 % CI = 1.63-2.17) and in those with co-occurring use of two or more substances (current smoking: OR = 5.25, 95 % CI = 4.63-5.95; nicotine dependence: OR = 3.24, 95 % CI = 2.72-3.87).

CONCLUSIONS

Co-occurring substance use was associated with smaller reductions in tobacco use, over time, and with increased odds of nicotine dependence. This suggests that co-occurring substance users should be regarded as a tobacco-related disparity group and prioritized for tobacco control interventions.

The Surgeon's Role in Addressing Racism and Achieving Health Equity

In the United States, the nation's health is not an organic outcome. It is not a coincidence that certain groups of people living in the United States experience higher premature death rates or poorer health outcomes than others. For centuries, racial and ethnic as well as geographic differences in health outcomes have been part of the American landscape, so entrenched in society that many people fail to recognize that health inequities were intentionally derived. A national crisis tends to magnify inequities in our society, but even more alarming is the fact that as the country becomes more racially and ethnically diverse in the coming years, the health inequities are projected to worsen if we do not proactively and immediately address them. As we continue to grapple with the lasting impact of the pandemic, it is of vital importance that we utilize this time to acknowledge, understand, and seriously address the health inequities that have historically plagued the country for over 400 years. As the United States works overtime to stem the tide of the COVID-19 pandemic, it must also work equally hard to move in a more equitable, inclusive, and healthier direction, not only because of the more than 83 000 Americans dying prematurely each year but also because of the economic and national security toll it will have if not effectively addressed.

Inequities along the Depression Care Cascade in African American Women: An Integrative Review

Depression represents a growing health problem and African American women (AAW) disproportionally experience increased risk and broad disparities in health care. This integrative review examines what is known about the equity of depression care provided to AAW. PubMed, PsychINFO, and Web of Science were searched through April 2020 for studies in peer-reviewed journals from 2015 to 2020. Across the studies (n = 7), AAW received inequitable care across a depression care cascade including lower rates of screening, treatment initiation, and guideline-concordant care. Here we explore individual-, relational-, and structural-level factors related to these disparities and implications for research, practice, and education.

Evaluating hypothesized explanations for the Black-white depression paradox: A critical review of the extant evidence

The Black-white Depression paradox, the lower prevalence of major depression among non-Hispanic Black (relative to non-Hispanic white) individuals despite their greater exposure to major life stressors, is a phenomenon that remains unexplained. Despite a decade plus of research, there is little clarity as to whether the paradoxical observations are an invalid finding, spuriously produced by selection bias, information bias, or confounding, or are a valid finding, representative of a true racial patterning of depression in the population. Though both artefactual and etiologic mechanisms have been tested, a lack of synthesis of the extant evidence has contributed towards an unclear picture of the validity of the paradox and produced challenges for researchers in determining which proposed mechanisms show promise, which have been debunked, and which require further study. The objective of this critical review is to assess the state of the literature regarding explanations for the Black-white depression paradox by examining some of the more prominent hypothesized explanatory mechanisms that have been proposed and assessing the state of the evidence in support of them. Included mechanisms were selected for their perceived dominance in the literature and the existence of at least one, direct empirical test using DSM major depression as the outcome. This review highlights the very limited evidence in support of any of the extant putative mechanisms, suggesting that investigators should redirect efforts towards identifying novel mechanisms, and/or empirically testing those which show promise but to date have been relatively understudied. We conclude with a discussion of the broader implications of the evidence for well-accepted social theories and raise questions regarding the use of DSM major depression to assess mental health burden in Black communities.

Allostatic load, metabolic syndrome and self-rated health in overweight/obese Non-Hispanic White, non-Hispanic Black and Mexican American adults

AIM

This study examined the associations of high allostatic load (h_ALS) and metabolic syndrome (MetS) with and self-rated poor health (SRPH) in overweight/obese non-Hispanic White (NHW), non-Hispanic Black (NHB), and Mexican American (MA) adults.

METHODS

The 2015-16 and 2017-18 US National Health and Nutrition Examination Survey data (n = 4403) were used for this study.

RESULTS

Rates of h_ALS in overweight/obese NHW, NHW, and MA participants were 56.9%, 58.8%, and 51.9%, respectively (P < .05). The corresponding rates for MetS were 26.9%, 31.9%, and 46.5%, respectively. High ALS was associated with 2.19 (95% CI: 1.87-4.59), 1.82 (1.42-2.58), and 1.47 (95% CI: 1.08-1.64) increased odds of SRPH in overweight/obese NHW, NHB, and MA, respectively, after adjusting for age, education, gender, income, lifestyle behaviors, and marital status. The corresponding values for MetS were 1.86 (95% CI: 1.54-2.40), 2.77 (95% CI: 1.36-5.63), and 1.22 (95% CI: 1.06-2.32), respectively.

CONCLUSIONS

The effect of h_ALS on SRPH was much stronger in NHW, while the effect of MetS was strongest among NHB overweight/obese adults. The result of this study provides further evidence in favor of race/ethnic-tailored interventions, including education and weight control to reduced risks of bodywear and tear and SRPH.

Combined Effect of Lead Exposure and Allostatic Load on Cardiovascular Disease Mortality-A Preliminary Study

This study explores the combined effect of lead (Pb) exposure and an index of chronic physiological stress on cardiovascular disease mortality using data from the National Health and Nutrition Examination Survey (NHANES) 1999-2008 linked to 1999-2014 National Death Index data. Chronic physiological stress was measured using the allostatic load (AL) index, which was formed by analyzing markers from the cardiovascular, inflammatory, and metabolic systems, with Pb levels, assessed using blood lead levels (BLL). The dataset was analyzed with statistical techniques to explore (a) the relationship between Pb exposure and AL, and (b) the combined role of Pb and AL on cardiovascular disease mortality. Results indicated that AL was more elevated in those with BLLs above the 50th percentile in the US population and that those with elevated AL were more likely to have high BLL. Finally, the interaction of AL and BLL significantly increased the likelihood of cardiovascular disease mortality. These findings highlight the need for considering the totality of exposures experienced by populations to build holistic programs to prevent Pb exposure and reduce stressors to promote optimal health outcomes and reduce cardiovascular mortality risk.

Socio-Cultural Subgroups of Latina/o Immigrants: A Latent Profile Analysis

Socio-cultural factors, such as familismo, social support, machismo, and multigroup ethnic identity, are strongly associated with Latina/o immigrants' alcohol misuse and depressive symptoms. However, research has rarely explored whether unobserved groups of Latina/o immigrants with similar socio-cultural factors exist. Latent Profile analysis can illuminate which subgroups to target, or which socio-cultural factors need to be supported, to have an impact on the prevention and treatment of alcohol use and/or depression in the Latina/o immigrant population. Cross sectional data from on ongoing longitudinal investigation was utilized (N= 518 Latina/o adults living in Miami-Dade County, Florida and have immigrated to the US within one year prior to assessment). Latent Profile Analyses (LPA) were conducted utilizing validated measures of familismo, social support, neighborhood collective efficacy, ethnic identity, machismo, caballerismo, and marianismo. The LPA revealed three, significantly different profiles: (1) low socio-cultural protection (n=155, 29.98%), (2) high socio-cultural protection (n=21, 4.06%), and (3) high socio-, low-cultural protection (n=341, 65.96%). Profile membership was associated significantly with immigrant documentation status, education level, and past family history of substance use. Results indicate that Latina/o immigrants in the low socio-cultural protection group had significantly higher alcohol use compared to high socio-, low cultural protection group. No significant differences were found for depressive symptoms. We discuss implications of our findings and encourage researchers to continue to unpack the complexities associated with socio-cultural factors and Latina/o mental and behavioral health. Specifically, research should focus on socio-cultural factors can provide protection from negative health outcomes and increase resiliency among this population.

Depressive symptoms, childhood maltreatment, and allostatic load: The importance of sex differences

OBJECTIVE

Roughly half the individuals who experience childhood maltreatment also experience depressive symptoms in adulthood; however, many current treatments are ineffective. Allostatic load (AL) offers a method of exploring this relationship through the lens of biometric dysregulation that may explain these increased odds for depressive symptoms in adulthood. We attempted to expand the limited research base on AL, depressive symptoms, and childhood maltreatment by examining how these variables are associated in a U.S. community sample.

METHOD

Data were acquired through secondary analysis of the Midlife in the United States Refresher biomarker survey (n = 691). Depression severity, measured by the Center for Epidemiologic Studies Depression Scale, served as the dependent variable, while summed scores for the Childhood Trauma Questionnaire, and a 16 measure AL index served as independent variables. All analyses were stratified by sex (n male = 347, n female = 344). The Perceived Stress Scale was included to control for recent stress. An OLS regression was used to understand the relationship between depression and predictor variables before then being tested for the possible mediating role of AL.

RESULTS

Comparison of OLS models yielded notable differences in predicting depressive symptoms between males and females, namely that while maltreatment was significant for both groups, AL was only significant for females. Mediation by allostatic load was not significant for males or females.

CONCLUSION

We explored the possible mediation of childhood maltreatment and adulthood depressive symptoms by AL. While our study did not confirm mediation, this was the first known study to explore these relationships in a U.S., community sample. Sex stratification reveals a clear need for accounting for sex differences in predictor variables for future studies.

Barriers and Facilitators of Smoking Cessation among Latinos Living with HIV: Perspectives from Key Leaders of Community-Based Organizations and Clinics

The purpose of this study was to identify the perspectives from key leaders of community-based organizations (CBOs) and clinics serving people living with HIV on barriers and facilitators of smoking cessation among Latino smokers living with HIV. Semi-structured interviews were conducted in English and Spanish with 10 key leaders. Using a social ecological model, qualitative theoretical analysis was used to analyze the results. Participants identified barriers at the individual (e.g., low education level, HIV, and financial stress), interpersonal (e.g., language barriers, low social support), organizational (e.g., lack of smoking cessation resources and targeted interventions), community (e.g., HIV and mental health stigma), and policy (e.g., paperwork for insurance) level. Participants identified facilitators at the individual (e.g., high participation in trials, good medication adherence), interpersonal (e.g., no smoking in social circles), organizational (e.g., bilingual staff, culturally competent care), community (e.g., providing transportation, the coronavirus disease 2019 as an opportunity for smoking cessation), and policy level (e.g., existence of funding, comprehensive insurance programs). These results provide operational strategies to address smoking disparities among Latino smokers living with HIV. Further research is needed on how to integrate these perspectives into effective smoking cessation interventions.

Explaining the Black-white depression paradox: Interrogating the Environmental Affordances Model

The Environmental Affordances (EA) model posits that Black Americans' engagement with unhealthy behaviors (i.e. smoking, alcohol use, eating calorie-dense foods) to cope with stressor exposure may simultaneously account for their observed greater risk of chronic physical illness, and their observed equal or lesser prevalence of depression, relative to white Americans - the so-called "Black-white depression paradox." However, the specific mechanisms through which such effects might arise have been theorized and analyzed inconsistently across studies, raising concerns regarding the appropriateness of existing empirical tests of the model as well as the validity of the conclusions. We specify the two mechanisms most consistent with the EA model - 'Mediation-only' and 'Mediation and Modification' - and derive a priori predictions based on each. We systematically test these pathways using a subset of 559 participants of the Child Health and Development Study who were included in an adult follow-up study between 2010 and 2012 and self-identified as Black or white. Results failed to support either of the two mechanisms derived from the EA model, challenging the validity and utility of the model for explaining racial differences in depression; efforts to develop alternative hypotheses to explain the paradox are needed.

Emergence of racial/ethnic and socioeconomic differences in objectively measured sleep-wake patterns in early infancy: results of the Rise & SHINE study

STUDY OBJECTIVES

To characterize objectively assessed sleep-wake patterns in infants at approximately 1 month and 6 months and examine the differences among infants with different racial/ethnic backgrounds and household socioeconomic status (SES).

METHODS

Full-term healthy singletons wore an ankle-placed actigraph at approximately 1 month and 6 months and parents completed sleep diaries. Associations of racial/ethnic and socioeconomic indices with sleep outcomes were examined using multivariable analyses. Covariates included sex, birth weight for gestational age z-score, age at assessment, maternal education, household income, bed-sharing, and breastfeeding.

RESULTS

The sample included 306 infants, of whom 51% were female, 42.5% non-Hispanic white, 32.7% Hispanic, 17.3% Asian, and 7.5% black. Between 1 month and 6 months, night sleep duration increased by 65.7 minutes (95% CI: 55.4, 76.0), night awakenings decreased by 2.2 episodes (2.0, 2.4), and daytime sleep duration decreased by 73.3 minutes (66.4, 80.2). Compared to change in night sleep duration over this development period for white infants (82.3 minutes [66.5, 98.0]), night sleep increased less for Hispanic (48.9 minutes [30.8, 66.9]) and black infants (31.6 minutes [-5.9, 69.1]). Night sleep duration also increased less for infants with lower maternal education and household income. Asian infants had more frequent night awakenings. Adjustment for maternal education and household income attenuated all observed day and night sleep duration differences other than in Asians, where persistently reduced nighttime sleep at 6 months was observed.

CONCLUSIONS

Racial/ethnic differences in sleep emerge in early infancy. Night and 24-hour sleep durations increase less in Hispanic and black infants compared to white infants, with differences largely explained by SES.

Allostatic Load Among U.S.- and Foreign-Born Whites, Blacks, and Latinx

INTRODUCTION

The objective of this study is to examine how allostatic load, a multidimensional measure of the body's cumulative response to stressors experienced throughout the life course, has changed over time and by age among U.S.- and foreign-born Whites, Blacks, and Latinx.

METHODS

Data were from 26,818 adult participants in the 2005-2018 National Health and Nutrition Examination Survey, a national repeated cross-sectional study. Allostatic load was measured based on 10 indicators of cardiovascular, metabolic, and immunologic risk. The analyses were conducted in March 2020.

RESULTS

Allostatic load increased over time across all groups. The difference between the first and last survey cycle was greatest among U.S.-born Black women (from 2.74 in 2005-2006 to 3.02 in 2017-2018), U.S.-born Latino men (from 2.69 to 3.09) and foreign-born Latino men (from 2.58 to 2.87). Aging gradients in allostatic load were steepest among foreign-born Blacks of both genders and foreign-born Latina women and flattest among U.S.-born and foreign-born Whites.

CONCLUSIONS

Chronic exposure to stressors leads to an erosion of health that is particularly severe among foreign-born Blacks and Latinx. Policies should seek to reduce exposure to structural and environmental risks and to ensure equitable opportunities to achieve optimal health among racial/ethnic minorities and immigrants.

Allostatic load and women's brain health: A systematic review

Allostatic load represents the 'wear and tear' of chronic stress on the brain and body that may differ between men and women. A small but growing number of studies are assessing allostatic load in relation to mental health. The objective of this systematic review was to (1) assess sex differences in allostatic load and (2) identify allostatic load associations that are specific to women. We systematically searched for allostatic load studies that included psychosocial causes and/or psychiatric consequences. Our search focused on allostatic load studies that disaggregated by sex and that include women. Sixty-two studies were included in this systematic review. First, men appear to have higher allostatic load than women. Second, women show gender-specific variation for numerous factors such as age, race/ethnicity, adversities, social support, and health behaviors that influence associations between allostatic load and mental health. Recommendations are made to guide researchers advance sex and gender approaches.

Mechanisms of Racial Health Disparities: Relationships between Coping and Psychological and Physiological Stress Responses

Objective

Psychological distress and physiological dysregulation represent two stress response pathways linked to poor health and are implicated in racial disparities in aging-related health outcomes among US men. Less is known about how coping relates to these stress responses. The purpose of this exploratory study was to examine whether midlife and older men's coping strategies and behaviors accounted, in part, for Black-White disparities in men's psychological and physiological stress responses.

Methods

We examined racial differences in 12 coping strategies (COPE Inventory subscales, religious/spiritual coping, and behaviors such as stress eating and substance use) and their relationships with psychological distress (Negative Affect scale) and physiological dysregulation (blunted diurnal cortisol slopes) using regression models and cross-sectional data from 696 Black and White male participants aged 35-85 years in the National Survey of Midlife Development in the United States (MIDUS) II, 2004-2006.

Results

Black men exhibited more psychological distress and physiological dysregulation than White men. Black and White men reported comparable use of most coping strategies, none of which demonstrated similar relationships with both stress responses. Coping strategies explained variations in psychological distress consistent with conventional protective-harmful categorizations. Coping accounted for racial disparities in men's psychological distress, as Black men reported using harmful strategies more often and were more susceptible to their negative effects. Neither differential use of coping strategies nor differing relationships accounted for racial disparities in physiological dysregulation.

Conclusions

Findings revealed complex relationships between coping and psychological and physiological stress responses and suggest the importance of differing approaches to reducing associated racial health disparities among men.

Pre-diagnostic allostatic load and health-related quality of life in a cohort of Black breast cancer survivors

PURPOSE

To determine the association of pre-diagnostic allostatic load (AL) with health-related quality of life (HRQOL) among Black women with breast cancer.

METHODS

In a sample of 409 Black women with non-metastatic breast cancer enrolled in the Women's Circle of Health Follow-Up Study (WCHFS), two pre-diagnostic AL measures were estimated using medical records data from up to 12 months prior to breast cancer diagnosis: AL-lipid/metabolic profile-based measure and AL-inflammatory profile-based measure. HRQOL was assessed approximately 24 months post diagnosis, using the Functional Assessment of Cancer Therapy-Breast Cancer (FACT-B) instrument, including 5 subscale scores [presented by physical well-being (PWB), social & family well-being (SFWB), emotional well-being (EWB), functional well-being (FWB), and breast cancer-specific scale (BCS)] and 3 derived total scores [presented by trial outcome index (TOI), Functional Assessment of Cancer Therapy-General (FACT-G) and FACT-B]. We used multivariable logistic regression models, using dichotomized AL scores (lower AL: 0-3 points, higher AL: 4-8 points), to assess the associations between the two pre-diagnostic AL measures and HRQOL.

RESULTS

Higher pre-diagnostic AL was associated with poorer FWB and lower FACT-G, but these associations were statistically significant for the AL-inflammatory profile-based measure (FWB: OR 1.63, 95% CI 1.04, 2.56; FACT-G: OR 1.62, 95% CI 1.04, 2.54), but not the AL-lipid/metabolic profile-based measure (FWB: OR 1.45, 95% CI 0.81, 2.59; FACT-G: OR 1.33, 95% CI 0.75, 2.37).

CONCLUSION

These findings suggest that higher AL, particularly when measured using the inflammatory profile-based measure, was associated with poorer HRQOL, namely FWB and FACT-G, among Black breast cancer survivors.

Association of Psychosocial Symptoms, Blood Pressure, and Menopausal Status in African-American Women

African-American women have disproportionate rates of hypertension that can be further complicated as they transition through menopause. Stress, coupled with depression and hypertension in perimenopausal African-American women has not been fully explored. This study examines the associations of stress, depression, and social support on systolic blood pressure (SBP) among a sample of 184 perimenopausal African-American women. We used descriptive statistics, Pearson's correlation, and logistic regression to analyze data stratified by menopausal status (perimenopausal or menopausal) and SBP status (<130 mmHg vs. >130 mmHg). Women classified as menopausal reported higher levels of stress and depressive symptoms, and lower levels of social support. Age, body mass index (BMI), health insurance, and perceived health status were significant predictors of SBP in menopausal women. Stress, depression, and social support did not play a role in SBP. It is necessary that future research focus on reducing cardiovascular risk include addressing menopausal health.

Adverse Childhood Experiences, Smoking and Alcohol Use, and Allostatic Load Among People Living with HIV

Allostatic load is an indicator of multisystem physiologic dysregulation that may arise from prolonged or accumulated exposure to stress, including adverse childhood experiences (ACEs) and chronic stressors persisting into adulthood. People living with HIV (PLWH) may be particularly vulnerable given their high burdens of adversity across the life course. Using data from a cohort of middle aged PLWH, we examined associations between ACEs and two measures of allostatic load. In order to determine whether the negative impact of ACEs on allostatic load operates through increasing the adoption of adverse coping behaviors, we tested for mediation by smoking and alcohol use. PLWH who had experienced 4 or more ACEs had on average higher allostatic load in adulthood compared to those who experienced fewer. Neither smoking nor alcohol use mediated this relationship, however, suggesting alternative mechanisms may be at play.

The Role of Neighborhood Experiences in Psychological Distress among African American and White Smokers

Residential area characteristics and discrimination have been associated with psychological distress. Differences in these relationships across racial groups are not well understood. We examined the relative role of perceived discrimination, neighborhood problems and neighborhood cohesion/trust in explaining differences in psychological distress (indicated by anxiety and depressive symptoms) between 224 African American and 225 White smokers (income ≤ 400% federal poverty level) in a smoking cessation intervention study. Surveys were linked to US census-tract data. We conducted random intercept Poisson multi-level regression models and examined interactions between race and neighborhood experiences. African Americans had greater risk of anxiety and depressive symptoms and greater individual and neighborhood disadvantage than Whites. Controlling for objective neighborhood characteristics, when perceived discrimination and perceived neighborhood characteristics were added to the regression models the association between anxiety symptoms and race were no longer statistically significant; the association between depressive symptoms and race decreased but remained statistically significant. Lower neighborhood social cohesion/trust and greater neighborhood problems increased depressive symptoms for African Americans, but not for Whites. Perceived discrimination and neighborhood social cohesion/trust outweighed the importance of race in explaining anxiety symptoms. These findings underscore the need for multi-level interventions addressing social and environmental contexts.

Household Food Insecurity and the Association with Cumulative Biological Risk among Lower-Income Adults: Results from the National Health and Nutrition Examination Surveys 2007-2010

Household food insecurity has been associated with adverse health outcomes; however, the mechanisms underlying these associations are not well-defined. Using data from 5005 adults from the 2007-2010 National Health and Nutrition Examination Surveys (NHANES), we examined associations between household food insecurity and cumulative biological risk, a measure of the body's physiological response to chronic stress. Household food security was assessed using the 18-item Household Food Security Survey Module. Marginal food security refers to 1-2 positive responses, and food insecurity refers to ≥3 positive responses. The cumulative biological risk scores were calculated based on the distributions of ten biomarkers from the cardiovascular, metabolic, and immune systems. Elevated biological risk was defined as a risk score of ≥3. Multivariable regression models were used to examine associations between food security and cumulative biological risk scores, adjusting for sociodemographic characteristics. After multivariable adjustment, food insecurity was associated with a 0.14-unit higher cumulative biological risk score (95% CI 0.05-0.22, p-trend = 0.003) and higher odds of elevated biological risk (OR 1.20, 95% CI 1.05-1.37, p-trend = 0.003). These associations differed by gender. Among women, food insecurity was associated with 0.30-unit higher cumulative biological risk score (95% CI 0.14-0.45, p-trend = 0.0004) and higher odds of elevated biological risk (OR 1.61, 95% CI 1.29-2.00, p-trend < 0.0001). These associations were not observed in men. Women experiencing food insecurity demonstrated elevated levels of biological risk. These findings support the hypothesis that food insecurity may be associated with women's chronic health outcomes through the pathway of chronic stress. Further research is needed to understand why these associations were not observed in men.

Dietary Approaches to Stop Hypertension (DASH) Score and Its Association with Sleep Quality in a National Survey of Middle-Aged and Older Men and Women

Complex processes appear to link sleep duration and quality with dietary patterns. Numerous studies show healthful benefits of the Dietary Approaches to Stop Hypertension (DASH) diet, but few have examined its association with sleep duration or quality. The current study tested cross-sectional associations of DASH diet quality score with sleep quality among adults. Analyses of participants were from the 2005–2008 wave of the National Health and Nutrition Examination Surveys (n = 3941 adults ≥30 years of age, complete data). We performed sex- and age group-stratified multiple OLS regression analyses with DASH total score and components as main predictors and sleep quality as main outcomes, adjusting sequentially for socio-demographic, behavioral and health-related factors. Sex and age differences in associations of DASH with sleep quality, adjusting for covariates, were also examined by incorporating two-way interaction terms between sex/age and the DASH score in each unstratified model. We found that the DASH diet score was inversely related to poor sleep-related daytime dysfunction adjusted by age, sex, demographic and socio-economic factors. Some sex-specific associations were detected between DASH diet component scores and sleep quality. Notably, the potassium DASH component was inversely associated with Factor 1 (“sleepiness and sleep disturbance”) among women. The fiber DASH component was associated with better sleep quality and inversely related to Factor 2 (“sleep-related daytime dysfunction”) in younger subjects. This study indicates health benefits of the DASH diet for sleep duration and quality. Future longitudinal studies and randomized placebo-controlled trials are required to ascertain protective effects.

Mechanisms of Racial Health Disparities: Evidence on Coping and Cortisol from MIDUS II

OBJECTIVE

Blunted patterns of daily cortisol, an indicator of hypothalamic-pituitary-adrenal (HPA) axis stress response system dysregulation, are implicated in poor health outcomes and racial health disparities. It is unknown how coping-an important, but understudied, component of the stress-health disparities relationship-relates to these biological mechanisms of health.

METHODS

This study investigated relationships, including racial differences, between 12 coping strategies and early-day cortisol changes (diurnal cortisol slopes from peak to before lunch) among 700 35-85-year-old Black and White male participants in the National Survey of Midlife Development in the United States (MIDUS) II. Cognitive-oriented (e.g., positive reinterpretation, denial, religious/spiritual) and behavioral (e.g., stress eating, substance use) coping strategies were examined.

RESULTS

Overall, Black and White men used similar coping strategies. Most coping strategies were not associated with men's cortisol slopes. Religious/spiritual coping was associated with steeper (more robust) cortisol slopes among White (b = - 0.004, t = - 3.28, p = 0.001) but not Black men. Drug use was associated with steeper cortisol slopes among Black (b = - 0.095, t = - 2.87, p = 0.004) but not White men.

CONCLUSIONS

This exploratory study increases our understanding of relationships between coping and stress-related biological mechanisms underlying racial health disparities among men in later life. With some notable exceptions, men's coping strategies were not associated with their diurnal cortisol slopes. This suggests that the coping strategies currently used by older Black and White men may not be important factors, as determinants or intervention targets, in disparities in diurnal cortisol slopes and associated health outcomes among men in this age group.
