Perceived racism in relation to weight change in the Black Women's Health Study

Discrimination in Medical Settings across Populations: Evidence From the All of Us Research Program

INTRODUCTION

Discrimination in medical settings (DMS) contributes to healthcare disparities in the United States, but few studies have determined the extent of DMS in a large national sample and across different populations. This study estimated the national prevalence of DMS and described demographic and health-related characteristics associated with experiencing DMS in seven different situations.

METHODS

Survey data from 41,875 adults participating in the All of Us Research Program collected in 2021-2022 and logistic regression were used to examine the association between sociodemographic and health-related characteristics and self-reported DMS among adults engaged with a healthcare provider within the past 12 months. Statistical analysis was performed in 2023-2024.

RESULTS

About 36.89% of adults reported having experienced at least one DMS situation. Adults with relative social and medical disadvantages had higher prevalence of experiencing DMS. Compared to their counterparts, respondents with higher odds of experiencing DMS in at least one situation identified as female, non-Hispanic Black, having at least some college, living in the South, renter, having other living arrangement, being publicly insured, not having a usual source of care, having multiple chronic conditions, having any disability, and reporting fair or poor health, p<0.05.

CONCLUSIONS

The findings indicate a high prevalence of DMS, particularly among some population groups. Characterizing DMS may be a valuable tool for identifying populations at risk within the healthcare system and optimizing the overall patient care experience. Implementing relevant policies remains an essential strategy for mitigating the prevalence of DMS and reducing healthcare disparities.

Use of calibration to improve the precision of estimates obtained from All of Us data

OBJECTIVES

To highlight the use of calibration weighting to improve the precision of estimates obtained from All of Us data and increase the return of value to communities from the All of Us Research Program.

MATERIALS AND METHODS

We used All of Us (2017-2022) data and raking to obtain prevalence estimates in two examples: discrimination in medical settings (N = 41 875) and food insecurity (N = 82 266). Weights were constructed using known population proportions (age, sex, race/ethnicity, region of residence, annual household income, and home ownership) from the 2020 National Health Interview Survey.

RESULTS

About 37% of adults experienced discrimination in a medical setting. About 20% of adults who had not seen a doctor reported being food insecure compared with 14% of adults who regularly saw a doctor.

CONCLUSIONS

Calibration using raking is cost-effective and may lead to more precise estimates when analyzing All of Us data.

Sleep, Health Outcomes and Body Weight (SHOW) study: a measurement burst design study on sleep and risk factors for obesity in black emerging adults in North Carolina, USA

INTRODUCTION

Black emerging adults (18-28 years) have the highest risk of short sleep duration and obesity. This increased risk may be partly explained by greater stress levels, which may result from race-related stress (racial discrimination and heightened race-related vigilance) or living in more disadvantaged home and neighbourhood environments. Insufficient sleep may also impact obesity risk via several weight-related mechanisms including energy balance, appetite and food reward, cortisol profiles and hydration status. This paper describes the rationale, design and methods for the Sleep, Health Outcomes and Body Weight (SHOW) study. This study aims to prospectively assess the effects of sleep, race-related stress and home/neighbourhood environments on weight-related mechanisms and obesity markers (body weight, waist circumference and fat mass) in 150 black emerging adults.

METHODS AND ANALYSIS

The SHOW study follows a measurement burst design that includes 3, 7-day data collection bursts (baseline, 6-month and 12-month follow-ups). Sleep is measured with three methods: sleep diary, actigraphy and polysomnography. Energy balance over 7 days is based on resting and postprandial energy expenditure measured via indirect calorimetry, physical activity via accelerometry and self-reported and ad libitum energy intake methods. Self-reported methods and blood biomarkers assess fasting and postprandial appetite profiles and a behavioural-choice task measures food reward. Cortisol awakening response and diurnal cortisol profiles over 3 days are assessed via saliva samples and chronic cortisol exposure via a hair sample. Hydration markers are assessed with 24-hour urine collection over 3 days and fasting blood biomarkers. Race-related stress is self-reported over 7 days. Home and neighbourhood environments (via the Windshield Survey) is observer assessed.

ETHICS AND DISSEMINATION

Ethics approval was granted by the University of North Carolina at Greensboro's Institutional Review Board. Study findings will be disseminated through peer-reviewed publications, presentations at scientific meetings and reports, briefs/infographics for lay and community audiences.

Perceived Interpersonal Racism in Relation to Incident Coronary Heart Disease Among Black Women

BACKGROUND

Racism is highly prevalent in the United States. Few data exist about whether perceived interpersonal racism is associated with risk of coronary heart disease (CHD).

METHODS

We followed 48 305 participants in the Black Women's Health Study through biennial mailed and Internet-based health questionnaires from 1997, when they provided information on perceived interpersonal racism and were free of cardiovascular disease and cancer, until the end of 2019. We averaged participant responses to 5 validated questions about perceived interpersonal racism in everyday activities, such as "people act as if they think you are dishonest." We summed the positive responses to 3 questions about perceived racism in interactions that involved jobs, housing, and police; scores ranged from 0 (no to all) to 3 (yes to all). CHD cases were defined as nonfatal myocardial infarctions confirmed through medical records, fatal cases identified through the National Death Index, and self-reported revascularization events. We used Cox proportional hazard models adjusting for major confounders to estimate hazard ratios (HRs).

RESULTS

During 22 years of follow-up, we identified 1947 incident CHD cases. For women who reported experiences of racism in employment, housing, or involving the police relative to women who reported no such experiences, the age-adjusted HR for CHD was 1.35 (95% CI, 1.13-1.61; Ptrend=0.006), and the multivariable HR for CHD was 1.26 (95% CI, 1.05-1.51; Ptrend=0.05). For women in the highest quartile of perceived interpersonal racism in daily life relative to women in the lowest quartile, the age-adjusted HR for CHD was 1.25 (95% CI, 1.07-1.46; Ptrend=0.006). After multivariable adjustment, the HR was attenuated and no longer statistically significant.

CONCLUSIONS

Perceived experiences of interpersonal racism in employment, in housing, and with the police were associated with higher incidence of CHD among Black women, whereas perceived racism in everyday life was not associated with higher risk.

Perceived Experiences of racism in Relation to Genome-Wide DNA Methylation and Epigenetic Aging in the Black Women's Health Study

BACKGROUND

African American women have a disproportionate burden of disease compared to US non-Hispanic white women. Exposure to psychosocial stressors may contribute to these health disparities. Racial discrimination, a major stressor for African American women, could affect health through epigenetic mechanisms.

METHODS

We conducted an epigenome-wide association study (EWAS) to examine the association of interpersonal racism (in daily life and in institutional settings) with DNA methylation in blood in 384 participants of the Black Women's Health Study (BWHS). We also evaluated whether a greater number of perceived experiences of racism was associated with epigenetic aging as measured using different methylation clocks. Models were adjusted for chronological age, body mass index, years of education, neighborhood SES, geographic region of residence, alcohol drinking, smoking, and technical covariates.

RESULTS

Higher scores of racism in daily life were associated with higher methylation levels at the cg04494873 site in chromosome 5 (β = 0.64%; 95% CI = 0.41%, 0.87%; P = 6.35E-08). We also replicated one CpG site, cg03317714, which was inversely associated with racial discrimination in a previous EWAS among African American women. In the BWHS, higher scores of racism in daily life were associated with lower methylation levels at that CpG site (β = -0.94%; 95% CI = -1.37%, -0.51%; P = 2.2E-05). Higher racism scores were associated with accelerated epigenetic aging in more than one methylation clock.

CONCLUSIONS

Exposure to discriminatory events may affect the epigenome and accelerate biological aging, which may explain in part the earlier onset of disease in African American women.

Direct and indirect associations of experience of racial discrimination, dietary patterns and obesity in adults from southern Brazil

OBJECTIVE

To analyse the direct and indirect associations of experience of racial discrimination on dietary patterns (DP), obesity and abdominal obesity.

DESIGN

This is a cross-sectional population-based study. The main exposure was self-reported experiences of racial discrimination (Experiences of Discrimination scale). The mediator variables were the DP: healthy, Brazilian traditional, sugar and carbohydrates, and fast food. The outcomes were obesity (BMI ≥ 30 kg/m2) and abdominal obesity (waist circumference ≥ 88 cm for women; ≥ 102 cm for men). Structural equation modelling was applied.

SETTING

Porto Alegre, Brazil.

PARTICIPANTS

Totally, 400 adults aged between 20 and 70 years were participated.

RESULTS

The mean age of participants was 47·2 years (sd = 13·9), and 75 % were women. Experiencing racial discrimination had a positive direct effect on obesity (healthy DP: β = 0·153, P < 0·05; Brazilian DP: β = 0·156, P < 0·05; sugar and carbohydrates DP: β = 0·156, P < 0·05; and fast-food DP: β = 0·153, P < 0·05) and abdominal obesity (healthy DP: β = 0·206, P < 0·01; Brazilian DP: β = 0·210, P < 0·01; sugar and carbohydrates DP: β = 0·204, P < 0·01; and fast-food DP: β = 0·204, P < 0·01). The experience of racial discrimination did not have a direct effect on DP, nor did it exert an indirect effect on obesity and abdominal obesity through any DP.

CONCLUSIONS

A higher experience of racial discrimination is associated with obesity and abdominal obesity, independent of diet.

Post-diagnosis weight trajectories and mortality among women with breast cancer

Weight gain after breast cancer diagnosis is associated with adverse health outcomes. Yet, few studies have characterized post-diagnosis weight change in the modern treatment era or populations most at risk for weight changes. Among women diagnosed with stages I-III breast cancer in the Smilow Care Network (2013-2019; N = 5441), we abstracted demographic and clinical characteristics from electronic health records and survival data from tumor registries. We assessed if baseline characteristics modified weight trajectories with nonlinear multilevel mixed-effect models. We evaluated body mass index (BMI) at diagnosis and weight change 1-year post-diagnosis in relation to all-cause and breast cancer-specific mortality with Cox proportional hazard models. Women had 34.4 ± 25.5 weight measurements over 3.2 ± 1.8 years of follow-up. Weight gain was associated with ER/PR-, HER2+ tumors, BMI ≤ 18.5 kg/m2, and age ≤ 45 years (+4.90 kg (standard error [SE] = 0.59), +3.24 kg (SE = 0.34), and +1.75 kg (SE = 0.10), respectively). Weight loss was associated with BMI ≥ 35 kg/m2 and age ≥ 70 years (-4.50 kg (SE = 0.08) and -4.34 kg (SE = 0.08), respectively). Large weight loss (≥10%), moderate weight loss (5-10%), and moderate weight gain (5-10%) 1-year after diagnosis were associated with higher all-cause mortality (hazard ratio [HR] = 2.93, 95% confidence interval [CI] = 2.28-3.75, HR = 1.32, 95% CI = 1.02-1.70 and HR = 1.39, 95% CI = 1.04-1.85, respectively). BMI ≥ 35 kg/m2 or BMI ≤ 18.5 kg/m2 at diagnosis were also associated with higher all-cause mortality. Weight change after a breast cancer diagnosis differed by demographic and clinical characteristics highlighting subgroups at-risk for weight change during a 5-year period post-diagnosis. Monitoring and interventions for weight management early in clinical care are important.

Cardiovascular disease in Filipino American men and women: A 2023 update

With more than 4.2 million people, Filipino Americans are the third largest Asian group in the US and the largest Southeast Asian group in the country. Despite relatively favorable average socioeconomic indicators compared to the general US population, Filipino Americans face a significant burden of traditional cardiovascular risk factors, particularly among men. Moreover, Filipino Americans have high rates of cardiovascular death, often occurring at a younger age compared to other minority groups and Non-Hispanic White adults. In view of these trends, in 2010 the American Heart Association designated Filipino Americans as a high cardiovascular risk group. Despite this, in 2023, Filipino Americans remain underrepresented in landmark cardiovascular cohort studies and are often over looked as a group at increased cardiovascular risk. In this updated narrative review, we summarize the current state of knowledge about the burden of cardiovascular risk factors and diseases experienced by the Filipino American population. Our aim is to inform enhanced clinical, population, and policy-level prevention interventions and boost research in this space.

Research on Health Disparities: Strategies and Findings From the Black Women's Health Study

The American Journal of Epidemiology has been a platform for findings from the Black Women's Health Study (BWHS) that are relevant to health disparities. Topics addressed have included methods of follow-up of a large cohort of Black women, disparities in health-care delivery, modifiable risk factors for health conditions that disproportionately affect Black women, associations with exposures that are highly prevalent in Black women, and methods for genetic research. BWHS papers have also highlighted the importance of considering social context, including perceived experiences of racism, in understanding health disparities. In the future, BWHS investigators will contribute to documentation of the role that structural racism plays in health disparities.

"Does Religious Service Attendance Modify the Relationship between Everyday Discrimination and Risk of Obesity? Results from the Study on Stress, Spirituality and Health"

This study examined the association of everyday discrimination with risk of obesity and the potential modifying effect of religious service attendance. Participants included Black, South Asian, and white women in three cohort studies that belong to the Study on Stress, Spirituality and Health. Logistic regression models estimated odds of obesity classification (BMI ≥ 30) relative to experiences of everyday discrimination. In initial pooled analyses, high levels of discrimination were related to increased odds of obesity. Race-specific analyses revealed marginal associations for white and South Asian women. Among Black women, high levels of discrimination and religious service attendance were both associated with higher odds of obesity. However, among women who attended religious services frequently, higher levels of everyday discrimination were associated with slightly lower odds of obesity. These findings underline the complex association between obesity and religion/spirituality, suggesting that higher levels of discrimination may uniquely activate religious resources or coping strategies. Findings highlight the need for additional studies to examine the impact of everyday discrimination on risk of obesity across racial/ethnic communities and how religious practices or coping strategies might affect these dynamics.

Perceived Interpersonal Racism and Incident Stroke Among US Black Women

Importance

Black individuals in the US experience stroke and stroke-related mortality at younger ages and more frequently than other racial groups. Studies examining the prospective association of interpersonal racism with stroke are lacking.

Objective

To examine the association of perceived interpersonal racism with incident stroke among US Black women.

Design, Setting, and Participants

The Black Women's Health Study, a prospective cohort study of 59 000 Black women from across the US, assessed the longitudinal association between perceived interpersonal racism and stroke incidence. Stroke-free participants were followed up from 1997 until onset of stroke, death, loss to follow-up, or the end of the study period (December 31, 2019). Cox models were used to estimate hazard ratios (HRs) and 95% CIs, adjusting for major confounders, including education, neighborhood socioeconomic environment, and cardiometabolic factors. Data analysis was performed from March 2021 until December 2022.

Exposure

On a questionnaire completed in 1997, participants reported experiences of racism in everyday life and when dealing with situations that involved employment, housing, and interactions with police.

Main Outcomes and Measures

Strokes were identified through self-report on biennial questionnaires, medical records adjudication, and linkage with the National Death Index.

Results

In 1997, 48 375 Black women (mean [SD] age, 41 [10] years) provided information on perceived interpersonal racism and were free of cardiovascular disease and cancer. During the 22 years of follow-up, 1664 incident stroke cases were identified; among them, 550 were definite cases confirmed by neurologist review and/or National Death Index linkage. Multivariable HRs for reported experiences of racism in all 3 domains of employment, housing, and interactions with police vs no such experiences were 1.38 (95% CI, 1.14-1.67), a 38% increase, for all incident cases and 1.37 (95% CI, 1.00-1.88) for definite cases. For comparisons of women in the highest quartile of everyday interpersonal racism score vs women in the lowest quartile, multivariable HRs were 1.14 (95% CI, 0.97-1.35) for analyses that included all incident stroke and 1.09 (95% CI, 0.83-1.45) for analyses that included definite cases only.

Conclusions and Relevance

In this study, Black women who reported experiences of interpersonal racism in situations involving employment, housing, and interactions with police appeared to have an increased risk of stroke, even after accounting for demographic and vascular risk factors, suggesting that the high burden of racism experienced by Black US women may contribute to racial disparities in stroke incidence.

Racial discrimination predicts the increase in body weight and BMI in Black individuals from ELSA-Brasil cohort

We investigated whether racial discrimination accelerates the weight and Body Mass Index (BMI) gain in Blacks and Browns participants of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) in four years of follow-up. We compared body weight and BMI between the 1st (2008-2010) and 2nd visit (2012-2014) of 5,983 Blacks and Browns participants. Exposure to racial discrimination and covariates (age, sex, education, and research center) were obtained at the 1st visit. Linear mixed effects models stratified by race/skin color were used. Report of racial discrimination was more frequent among Blacks (32.1%) than Browns (6.3%). During the follow-up period, Blacks and Browns gained an average of 1.4kg and 1.2kg, respectively. This increase was greater among those who reported discrimination when compared to those who did not, both in Blacks (2.1kg vs.1.0kg, p < 0.001) and Browns (1.9kg vs. 1.1kg, p < 0.05). The results of the interaction between racial discrimination and time showed that Blacks, but not Browns, who reported racial discrimination had greater weight and BMI gains between visits. Our results suggest that reducing racial discrimination would contribute to prevent and/or control obesity increase in the country.

The effect of motivational interviewing and/or cognitive behaviour therapy techniques on gestational weight gain - a systematic review and meta-analysis

BACKGROUND

Women with gestational weight gain (GWG) that is below or above recommendations are at risk of adverse perinatal outcomes. Motivational interviewing and/or cognitive behaviour therapy have demonstrated efficacy in initiating and sustaining behaviour change, including weight control. The objective of this review was to investigate the effect of antenatal interventions that include components of motivational interviewing and/or cognitive behaviour therapy on gestational weight gain.

METHODS

This review was designed and reported in accordance with guidelines outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Five electronic databases were systematically searched to March 2022. Randomised controlled trials evaluating interventions with identified components of motivational interviewing and/or cognitive behaviour therapies were included. Pooled proportions of appropriate GWG and GWG above or below guidelines, and standardised mean difference for total gestational weight gain, were calculated. Risk of bias in included studies was evaluated using the Risk of Bias 2 tool, and the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) approach was used to evaluate the quality of evidence.

RESULTS

Twenty-one studies (8030 participants) were included. Overall, MI and/or CBT interventions had a small effect on the total gestational weight gain (SMD: -0.18, 95% confidence interval: -0.27 to -0.09, p < 0.001) and improved the proportion of women achieving recommended gestational weight gain (29% versus 23% in the comparison, p < 0.001). The GRADE assessment indicated that overall quality of evidence is very uncertain, however sensitivity analyses to account for high risk of bias produced similar results to original meta-analyses. The magnitude of effect was greater in women with overweight or obesity when compared to women with BMI < 25 kg/m².

CONCLUSION

Motivational interviewing and/or cognitive behaviour therapy techniques may be effective for promoting healthy gestational weight gain. Nevertheless, a high proportion of women do not achieve recommended gestational weight gain. Future interventions should consider factors, including clinician and consumer perspectives, in the design and delivery of psychosocial interventions that aim to support healthy gestational weight gain.

TRIAL REGISTRATION

The protocol for this review was registered with the PROSPERO International register of systematic reviews (registration number CRD42020156401).

Racism-Related Experiences and Adiposity: Findings From the Black Women's Experiences Living With Lupus (BeWELL) Study

INTRODUCTION

Studies suggest that higher rates of excess adiposity in Black women may in part be driven by experiences of racism. Racial microaggressions, which include unintentional and subtle slights and insults, and responses to racism such as racism-related vigilance, may contribute to adiposity in this population. This study examined these understudied racism-related facets as well as interpersonal racial discrimination in relation to adiposity in a cohort of Black women with systemic lupus erythematosus.

METHODS

Data are from the Black Women's Experiences Living with Lupus (BeWELL) Study (2015-2017; n = 432). Linear regression was used to examine adiposity measures (body mass index [BMI], percent body fat, and waist-to-hip ratio), measured during a physical examination, in relation to self-reported measures of racial microaggressions, racism-related vigilance, and interpersonal racial discrimination.

RESULTS

Compared with infrequent microaggressions, very frequent experiences of microaggressions were associated with 2.9 kg/m2 higher BMI (95% confidence [CI], 0.63-5.21) and 2.6% higher body fat (95% CI, 0.32-4.80) after adjusting for covariates. Racism-related vigilance, measured continuously, was positively associated with BMI (b = 0.84; 95% CI-0.08, 1.61) and percent body fat (b = 0.89; 95% CI, 0.14-1.64). Very frequent experiences of everyday discrimination were associated with a higher BMI (b = 2.70; 95% CI, 0.58-4.83) and waist-to-hip ratio (b = 0.32; 95% CI, 0.09-0.55) compared with less frequent everyday discrimination.

CONCLUSIONS

Our results suggest that various dimensions of racism are associated with excess adiposity. Efforts to address obesity among Black women with systemic lupus erythematosus should consider these multiple aspects to decrease racial inequities in adiposity.

The Association of Avoidance Coping with Gestational Weight Gain among Pregnant Black Women

Gestational weight gain (GWG) outside recommended parameters can lead to pregnancy or birth complications. Avoidance coping may influence GWG. We examined the association of avoidance coping with GWG among a sample of 112 pregnant Black women in the Midwest. Participants completed avoidance coping questionnaires at three time points throughout pregnancy. Data were abstracted from medical records for BMI and GWG. Overall, 23.2% gained inadequate weight, 30.4% adequate weight, and 46.4% excess weight. Multinomial logistic regression models indicated associations between avoidance coping and GWG adjusted for covariates. Participants with higher avoidance coping scores at 22-29 weeks' gestation were more likely to experience excess weight gain (odds ratio [OR] = 1.19, 95% CI [1.02, 1.37]). Participants with higher avoidance coping scores at 30-36 weeks' gestation were less likely to experience excess weight gain, (OR = 0.82, 95% CI [0.72, 0.93]). The impact of higher avoidance coping on excess weight gain depends on the time period in pregnancy.

Exposure to anti-Black Lives Matter movement and obesity of the Black population

RATIONALE

Black Lives Matter (BLM) is a social movement against systematic injustice and police violence toward Black people whose goal is to ensure their safety and the expression of their culture. As BLM gained momentum, counter-movements emerged, such as All Lives Matter (ALM), White Lives Matter (WLM), and Blue Lives Matter (BlueLM). Because they undermine support for Black people's safety and culture, exposure to stances against BLM can be a race-related stressor. Although the perception of racial discrimination has been associated with negative health outcomes in Black people, it is not clear whether exposure to negative stances on a race-related social issue is associated with worse health outcomes.

OBJECTIVE

We investigated whether living in areas of the United States with a high prevalence of negative stances on BLM is associated with worse health outcomes, such as higher body mass index (BMI) and prevalence of obesity.

METHODS

We scraped geo-coded tweets (N = 51,020) that contained #BLM, #ALM, #WLM, and #BlueLM from 2014 to 2016. We determined the stances of the tweets on BLM using machine learning algorithms and aggregated stances at the metropolitan or micropolitan statistical area (MMSA) levels. Participants' BMI and obesity status were derived from the 2017 BRFSS SMART data in 76 MMSAs, as compiled by the Centers for Disease Control and Prevention (N = 20,530).

RESULTS

After controlling for individual- and regional-level covariates, regional measures of racism and police brutality rate, and baseline BMI in 2014 aggregated on MMSA level, Black people had a higher BMI and prevalence of obesity in areas that showed higher negative stances on BLM. Stances against BLM were positively associated with implicit racism against Black people and can be an acute race-related stressor associated with negative downstream health outcomes.

CONCLUSION

Negative societal sentiments around race-related issues may be detrimental to the health outcomes of minority populations.

Association between Proximity to Food Sources and Dietary Behaviors in Black and White College Graduates

OBJECTIVES

Unequal access to healthy food environments is often implicated in racial inequities in health and behaviors that are largest among college graduates. The aim of this study was to determine associations between perceived proximity to food sources and dietary behaviors between black and white college graduates.

METHODS

In a cross-sectional online survey of dietary behaviors between black and white adults who have a ≥ 4-year bachelor's degree, respondents were asked how long it typically takes for them to get to grocery stores and fast-food restaurants from home. We used ordinal logit regression models to assess associations between perceived proximity to food sources and dietary behaviors.

RESULTS

Among black men, perceiving that a grocery store was ≥ 10 minutes from their home was associated with lower fruit consumption (beta=-0.94, SE=0.48). Perceiving that a grocery store was ≥ 10 minutes from their home was associated with more frequent fast-food consumption among black men (beta=1.21, SE=0.39), Black women (beta=0.98, SE=0.34), and white men (beta=0.74, SE=0.30).

CONCLUSIONS

The associations between perceived proximity to food sources and dietary behaviors differ by race and sex among college graduates with important implications for racial disparities in diet quality and obesity across SES.

The Association Between Perceived Discrimination and BMI Trajectory: A Prospective Study of African American and White Adults

Evidence suggests that socioenvironmental stressors, such as discrimination, may serve as determinants of the ongoing obesity epidemic and persisting disparities in obesity prevalence. The objectives of these analyses were to examine whether perceived discrimination was associated with body mass index (BMI) trajectory and whether this relationship differed by race or sex. Data for these analyses came from the Healthy Aging in Neighborhoods of Diversity across the Life Span study, a prospective cohort study in Baltimore City. Mixed-effects linear regression was used in a sample of 1962 African American and white adults to test our hypotheses. We found that race was an effect modifier in the relationship between perceived discrimination and BMI trajectory (B = 0.063, P = .014). Specifically, higher baseline perceived discrimination was associated with positive BMI trajectory in African American adults (B = 0.031, P = .033) but not in white adults (B = -0.032 P = .128). In this longitudinal study of African American and white adults, the relationship between perceived discrimination and BMI trajectory differed by race. Future research should be conducted in diverse samples to understand the risk socioenvironmental stressors pose on the development and progression of overweight and obesity, in addition to how these differ in subgroups.

An Acceptance Based Lifestyle Intervention in Black Breast Cancer Survivors with Obesity

To assess the feasibility and early efficacy of a combined lifestyle and acceptance-based therapy (ABT) intervention on weight loss at 16 weeks among Black breast cancer (BC) survivors with obesity. Thirty black breast cancer survivors with a BMI ≥ 30 kg/m2 at least 6 months post-treatment were enrolled. Outcomes included feasibility process measures, physical well-being assessed using the subscale of QOL-Breast Cancer (QOL-BC), physical activity assessed by Global Physical Activity Questionnaire (GPAQ), and weight. Fisher's Exact/Chi-Squared tests and Wilcoxon rank-sum tests were used to explore differences between responders and non-responders, as well as within-group changes during the intervention. Within the first 4 weeks, responders (participants who lost any weight) lost a median of 2.6 lbs. compared to non-responders (no weight loss) who gained a median of 2.6 lbs. At 16 weeks, participants reported greater physical well-being (p < 0.0001), increased time in recreational activities (p = 0.03), and a median weight loss of 5.6 pounds in responders vs. 0.7 pounds in non-responders (p ≤ 0.001). Non-responders were more likely to have developed a new health condition compared to responders (44% vs. 0%; p = 0.014). In this study, weight loss at 4 weeks and new-onset health conditions were significant factors associated with non-response to the combined intervention. Black BC with obesity are at high risk for recurrent cancer and secondary health conditions. ABT may be a suitable adjunct therapeutic option to lifestyle interventions implemented soon after a cancer diagnosis to improve physical well-being, increase physical activity, and promote weight loss.

Addressing Structural Racism Is Critical for Ameliorating the Childhood Obesity Epidemic in Black Youth

Racism and childhood obesity are both pervasive factors adversely affecting the health and wellbeing of children and adolescents in the United States. The association between racism and obesity has been touched upon in the literature; yet most work has focused on a few dimensions of intersectionality of these two domains at one time. The renewed focus on structural racism as the primary contributor to distress of Black individuals in the United States has highlighted the urgency of identifying the contributions of racism to the childhood obesity epidemic. The current article is not a complete review of the literature, rather, it is meant to take a broad narrative review of the myriad ways in which racism contributes to the obesity epidemic in Black youth to serve as a call to action for more research, prevention, and intervention. The current article illustrates how a number of mechanisms for the etiology and maintenance of obesity are heavily influenced by racism and how addressing racism is critical for ameliorating the childhood obesity epidemic.

Coping styles moderate the relationship between perceived discrimination and eating behaviors during the transition to college

The transition to college is a critical developmental window during which eating behaviors are susceptible to dysregulation. Changes in exposure to discrimination contribute to alterations in eating behaviors, which may be exacerbated or attenuated by coping styles. The present longitudinal study examines whether increases in perceived discrimination predict increases in overeating and decreases in eating well during the transition to college. We expect that adaptive coping styles will buffer against, while maladaptive coping styles will exacerbate, the effects of increases in perceived discrimination on increases in overeating and decreases in eating well. First year students (n = 804) were assessed at two time points: the spring before freshman year (Time 1) and one year later during the spring semester of freshman year (Time 2). Two distinct coping styles emerged from a factor analysis: adaptive (active coping, planning, emotional support, positive reframing, acceptance, instrumental support) and maladaptive coping (denial, venting, self-blame, self-distraction). Increases in perceived discrimination, lower adaptive coping, and higher maladaptive coping had main effects for predicting more overeating at Time 2. Among students who reported increases in perceived discrimination, higher use of adaptive coping was associated with less overeating at Time 2 while higher use of maladaptive coping was associated with more overeating. While adaptive and maladaptive coping styles had main effects on eating well, change in perceived discrimination did not. Neither adaptive nor maladaptive coping styles interacted with change in perceived discrimination to predict eating well. Findings inform a gap in the literature about the relationship between discrimination and eating behaviors from a developmental perspective by demonstrating that adaptive and maladaptive coping styles influence the effects of changes in perceived discrimination on overeating during the college transition.

Neighborhood disadvantage and individual-level life stressors in relation to breast cancer incidence in US Black women

BACKGROUND

Research on psychosocial stress and risk of breast cancer has produced conflicting results. Few studies have assessed this relation by breast cancer subtype or specifically among Black women, who experience unique chronic stressors.

METHODS

We used prospective data from the Black Women's Health Study, an ongoing cohort study of 59,000 US Black women, to assess neighborhood- and individual-level psychosocial factors in relation to risk of breast cancer. We used factor analysis to derive two neighborhood score variables after linking participant addresses to US Census data (2000 and 2010) on education, employment, income and poverty, female-headed households, and Black race for all households in each residential block group. We used Cox proportional hazards regression to estimate hazard ratios (HR) and 95% confidence intervals (CI) adjusted for established breast cancer risk factors.

RESULTS

During follow-up from 1995 to 2017, there were 2167 incident invasive breast cancer cases (1259 estrogen receptor positive (ER +); 687 ER negative (ER-)). For ER- breast cancer, HRs were 1.26 (95% CI 1.00-1.58) for women living in the highest quartile of neighborhood disadvantage relative to women in the lowest quartile, and 1.24 (95% CI 0.98-1.57) for lowest versus highest quartile of neighborhood socioeconomic status (SES). For ER+ breast cancer, living in the lowest quartile of neighborhood SES was associated with a reduced risk of ER+ breast cancer (HR = 0.83, 95% CI 0.70-0.98). With respect to individual-level factors, childhood sexual abuse (sexual assault ≥ 4 times vs. no abuse: HR = 1.35, 95% CI 1.01-1.79) and marital status (married/living together vs. single: HR = 1.29, 95% CI 1.08-1.53) were associated with higher risk of ER+, but not ER- breast cancer.

CONCLUSION

Neighborhood disadvantage and lower neighborhood SES were associated with an approximately 25% increased risk of ER- breast cancer in this large cohort of Black women, even after control for multiple behaviors and lifestyle factors. Further research is need to understand the underlying reasons for these associations. Possible contributing factors are biologic responses to the chronic stress/distress experienced by individuals who reside in neighborhoods characterized by high levels of noise, crime and unemployment or the direct effects of environmental toxins.

Familial Financial Assistance and Body Mass Index in Black College Graduates

Racial disparities in obesity are larger between Black and White college graduates compared to disparities among those who did not complete high school. A possible explanation is that Black adults with higher socioeconomic status (SES) experience unique obesogenic determinants. Black adults who have completed a 4-year college degree can report "uplift stress" from providing financial assistance to family members. The aim of this study is to determine whether the association between familial financial assistance and body mass index (BMI) varies among college-educated Black women and men. This study utilized data from an online survey of Qualtrics standing panels including 451 non-Hispanic Black college graduates. Respondents were asked if they had provided or received any monetary gift or financial help from a family member in the past 12 months as well as their height and weight. Using linear regression and multiplicative interaction terms, the association between familial financial assistance and BMI was assessed by sex. Those who reported both giving and receiving familial financial assistance had higher BMI than those who neither gave nor received assistance (β = 2.80, standard error (s.e.) = 1.16). There was a significant interaction such that this association was observed among women only (β = 6.67, s.e. = 2.32). Future studies should seek to understand the gendered impact of familial financial assistance on BMI in college-educated Black women.

Black Psychology and Whiteness: Toward a Conceptual Model of Black Trauma through the Prism of Whiteness

The main objective of this article is to introduce and examine whiteness as a source of trauma for Black people. We explore Black psychology scholarship to conceptually ground whiteness as the impetus for racism, while identifying it as an interpersonal, psychosocial, and contextual phenomenon that informs the race-based traumatic experiences of Black people. The primary factors constituting whiteness are ethnocentric monoculturalism, White standardization, ontological expansiveness, White emotions, attitudes, reactions to race, and White privilege. While racism operates through oppression and exclusion to produce trauma among Black people, we argue that whiteness operates similarly to produce race-based traumatic stress. With this premise, we offer and explain a conceptual model to promote empirical research that identifies and operationalizes whiteness and its components as observable contributors to the traumatic experiences of Black persons.

Racial inequality, racial discrimination and obesity incidence in adults from the ELSA-Brasil cohort

BACKGROUND

This study investigated whether self-reported race/skin colour and perceived racial discrimination predict higher obesity incidence after approximately 4-year follow-up of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). We also investigated whether these associations are modified by educational level.

METHODS

Following exclusion of individuals defined as obese (body mass index ≥30 kg/m2) at baseline, associations between race/skin colour and obesity incidence between the first (2008-2010) and second (2012-2014) visits were investigated in 10 130 participants. Next, associations between perceived racial discrimination and obesity incidence among black (n=1532) and brown (n=2958) individuals were investigated separately. Racial discrimination (yes/no) was assessed using the Lifetime Major Event Scale. Logistic regression models adjusted for age, sex and research site were used. All analyses were stratified for educational level.

RESULTS

Obesity risk was higher in Blacks with high education compared with white individuals to the same education level (OR: 2.22; 95% CI 1.62 to 3.04) following adjustments. After adjustments, obesity incidence was higher among black individuals reporting racial discrimination compared with peers who did not report this experience, but only among the low education group (OR: 1.64; 95% CI 1.08 to 2.51). No statistical association with perceived discrimination was observed among brown individuals.

CONCLUSION

Results are congruent with findings from other studies reporting associations between racial inequality and obesity incidence and also suggest racial discrimination may be one of the mechanisms leading to such inequalities. Also, it supports the paradox theory by which education modify the association in distinct directions.

Perceived racial discrimination and healthy behavior among African Americans

OBJECTIVE

Numerous studies have found evidence of a link between perceived discrimination and unhealthy behavior, especially substance use. Within this body of literature, however, several studies have found unexpected evidence of a positive relation between perceived racial discrimination among African Americans-mostly women-and certain types of healthy behavior, primarily exercise and healthy eating. The current study further examined this positive relation, including an anticipated moderator: optimism. It also examined the relation between perceived racial discrimination and a correlate of unhealthy behavior: BMI.

METHOD

Six waves of data were collected over 14 years in three related samples of African Americans from families participating in the Family and Community Health Study. Each family included an adolescent (Mage = 10.5 at Wave 1), the adolescent's primary caregiver (Mage = 37), and, in some cases, an older sibling of that adolescent (Mage = 13). Wave 1 Ns were 889, 889, and 295, respectively. Healthy behavior was defined as diet and exercise.

RESULTS

There was very little evidence of a long-term relation between perceived racial discrimination and BMI in any sample, and no evidence of a relation between discrimination and healthy behavior among the males. However, correlational analyses revealed a positive prospective relation between discrimination and healthy behavior among all three groups of females; structural equation modeling indicated that this relation was stronger among women who were high in optimism.

CONCLUSIONS

Perceived racial discrimination does not appear to be related to BMI among African Americans, but it is related to healthy behavior among Black females who are high in dispositional optimism. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Understanding stigma and food inequity: a conceptual framework to inform research, intervention, and policy

There is increasing understanding that stigma associated with poverty, race, nationality, gender, obesity, and other intersecting, socially devalued characteristics is a key social determinant of health that plays a role in food inequities; yet, the processes linking stigma with food inequities are poorly defined. Building on prior conceptual and empirical stigma research in public health, this paper introduces The Stigma and Food Inequity Framework. Supporting empirical evidence for the associations proposed by the framework is reviewed. The framework proposes that stigma is manifested at the structural (e.g., neighborhood infrastructure and targeted marketing) and individual (e.g., internalized stigma and stereotypes) levels. These stigma manifestations are associated with food inequities via a series of mediating mechanisms, including access to resources, the home food environment, and psychosocial and behavioral processes, which ultimately undermine healthy food consumption, contribute to food insecurity, and impact diet quality. The framework further proposes that processes linking stigma with food inequities are situated within contexts of history, culture, and human development. Future directions to address stigma and enhance food equity include the value of addressing the broad range of underlying structural stigma manifestations when creating policy to promote food equity.

Race in association with physical and mental health among former professional American-style football players: findings from the Football Players Health Study

PURPOSE

Race differences in health are pervasive in the United States. American-style football players are a racially diverse group with social status and other benefits that may reduce health disparities. Whether race disparities in health exist among former professional football players, and whether they differ by era of play, is unknown.

METHODS

We examined the association of self-reported race with health outcomes (e.g., physical and cognitive function, pain, depression, and anxiety), among 3747 participants in the Football Players Health Study, comprising former National Football League players who played since 1960. We conducted analyses stratified by age.

RESULTS

Black players had increased risk of all five adverse health outcomes versus white players (risk ratio range = 1.36 to 1.89). Native Hawaiians and men of other races had greater risk of all health outcomes except impaired physical functioning, compared with white players (risk ratio range = 1.25 to 1.64). No clear patterns were observed by era of play. In general, race disparities were not accounted for by health-related exposures during playing years. Adjustment for current BMI somewhat attenuated associations.

CONCLUSIONS

Social and economic advantages of playing professional football did not appear to equalize race disparities in health.

Onset of Workplace Bullying and Risk of Weight Gain: A Multicohort Longitudinal Study

OBJECTIVE

This study aimed to examine the onset of workplace bullying as a risk factor for BMI increase.

METHODS

Repeated biennial survey data from three Nordic cohort studies were used, totaling 46,148 participants (67,337 participant observations) aged between 18 and 65 who did not have obesity and who were not bullied at the baseline. Multinomial logistic regression was applied for the analysis under the framework of generalized estimating equations.

RESULTS

Five percent reported onset of workplace bullying within 2 years from the baseline. In confounder-adjusted models, onset of workplace bullying was associated with a higher risk of weight gain of ≥ 1 BMI unit (odds ratio = 1.09; 95% CI: 1.01-1.19) and of ≥ 2.5 BMI units (odds ratio = 1.24; 95% CI: 1.06-1.45). A dose-response pattern was observed, and those exposed to workplace bullying more frequently showed a higher risk (P_trend  = 0.04). The association was robust to adjustments, restrictions, stratifications, and use of relative/absolute scales for BMI change.

CONCLUSIONS

Participants with exposure to the onset of workplace bullying were more likely to gain weight, a possible pathway linking workplace bullying to increased long-term risk of type 2 diabetes.

A Dream Deferred: African American Women's Diminished Socioeconomic Returns of Postponing Childbearing from Teenage to Adulthood

Background

Brookings Institution has identified postponing childbirth from teenage to adulthood as a major strategy that is needed for upward social mobility of women. However, according to the Minorities' Diminished Returns (MDRs), the associations between aspirations, investments, behaviors, and socioeconomic position (SEP) may be diminished for marginalized groups such as African Americans.

Objective

To extend the existing knowledge on the MDRs, the current study had two aims: First to compare White and African American women for the association between postponing childbearing to adulthood and SEP in a national sample of American women. Second, to test correlates of postponing childbearing to adulthood and SEP at birth with long term outcomes 15 years later when the child was 15 years old.

Methods

For this longitudinal study, data came from the Fragile Families and Child Well-being Study (FFCWS), a national longitudinal prospective study in the United States (US) that followed an ethnically diverse sample of women from childbirth for 15 years from 1998 to 2016. For the first aim, this study included 2679 women composed of 723 Whites and 1956 African Americans. For the second aim, among 1842 individuals who had available data 15 years later, we measured various economic, behavioral, and mental health outcomes when the child was 15 years old. For aim 1 we ran linear regression. Postponing childbearing to adulthood was the independent variable. The dependent variable, SEP (poverty) was treated as a continuous measure with higher score indicating more poverty. Confounders included marital status and delivery characteristics. For the aim 2, we ran Pearson correlation test (exploratory analysis) to test if baseline SEP correlates with future outcomes.

Results

Postponing childbearing from adolescence to adulthood was associated with higher SEP in adulthood, net of all confounders including marital status and education. We found a significant interaction between postponing childbearing from adolescence to adulthood and race on SEP, suggesting that the economic reward of postponing childbearing may be weaker for African American women than for White women.

Conclusions

Although postponing the age at childbirth is a recommended strategy for women who wish to maximize their chance of upward social mobility, this strategy may be associated with smaller economic returns for African American women than White women. The results can also be interpreted as MDRs in investments in terms of a postponing childbearing. In a fair society, the same investment should be similarly rewarded across diverse racial groups. In the reality, however, the US society differently rewards White and African American women who postpone childbearing. Research should explore the roles of social stratification, blocked opportunities, and concentrated poverty in explaining the unequal return of such an investment for African American and White women.

Understanding and effectively addressing disparities in obesity: A systematic review of the psychological determinants of emotional eating behaviours among Black women

Emotional eating may be a particularly important contributor to differences in body weight and weight loss response to behavioural interventions among non-Hispanic Black women. We performed a systematic review on the impact of psychological factors (stress, anxiety, depression, and discrimination) upon emotional eating and weight among non-Hispanic Black women, applying the Preferred Reporting Items for Systematic Reviews and Meta-analysis for relevant studies. The initial search yielded 4593 articles with 15 accepted for review. Based on this review, there is a suggestion that negative emotions, in particular, perceived stress, may be predictive of emotional eating among non-Hispanic Black women. Results from the only two longitudinal studies identified by the review indicate that stress influences emotional eating, and emotional eating predicts weight gain over time. Findings from this review highlight the need for more studies that examine various negative emotions that may lead to emotional eating and weight gain among non-Hispanic Black women. Findings from this review also highlight the need for more rigorous studies to differentiate the effects of emotional eating from that of the physiologic (ie, activation of the hypothalamic-pituitary axis) responses to stress and its impact on high-risk groups.

Perceived Discrimination and Trajectories of C-Reactive Protein: The Jackson Heart Study

INTRODUCTION

Perceiving discriminatory treatment may contribute to systemic inflammation, a risk factor of cardiovascular pathophysiology. This study evaluated the association of self-reported discrimination with changes in high-sensitivity C-reactive protein and the mediating role of adiposity.

METHODS

The sample included 5,145 African-Americans, aged 21-92 years, in the Jackson Heart Study. Everyday, lifetime, and burden from perceived discrimination comprised primary predictors in 3 sets of multivariable linear regression models of baseline (2000-2004) discrimination and natural logarithm of high-sensitivity C-reactive protein. Multivariable linear mixed models assessed mean changes in natural logarithm of high-sensitivity C-reactive protein over the study period (2000-2013). Mediation was quantified by percentage changes in estimates adjusted for BMI, waist circumference, and waist-to-height ratio. Multiple imputation addressed missingness in baseline covariates and in high-sensitivity C-reactive protein taken at all 3 study examinations. Analyses were conducted in 2018.

RESULTS

In cross-sectional analyses, male participants in the middle and highest tertiles of lifetime discrimination had natural logarithm of high-sensitivity C-reactive protein levels that were 0.13 (95% CI= -0.24, -0.01) and 0.15 (95% CI= -0.27, -0.02) natural logarithm(mg/dL) lower than those in the lowest tertile. In longitudinal analyses, all participants reporting more frequent everyday discrimination had a 0.07 natural logarithm(mg/dL) greater increase in natural logarithm of high-sensitivity C-reactive protein per examination than those reporting none (95% CI=0.01, 0.12). A similar trend emerged for lifetime discrimination and changes in natural logarithm of high-sensitivity C-reactive protein (adjusted mean increase per visit: 0.04 natural logarithm[mg/dL], 95% CI=0.01, 0.08). Adiposity did not mediate the longitudinal associations.

CONCLUSIONS

Everyday and lifetime discrimination were associated with significant high-sensitivity C-reactive protein increases over 13 years. The physiologic response to discrimination may lead to systemic inflammation.

Perceived racial discrimination and risk of insomnia among middle-aged and elderly Black women

STUDY OBJECTIVE

To assess whether perceived racial discrimination is associated with insomnia among Black women.

METHODS

Data on everyday and lifetime racism and insomnia symptoms were collected from questionnaires administered in the Black Women's Health Study, an ongoing prospective cohort of Black women recruited in 1995 from across the United States. In 2009, participants completed five questions on the frequency of discriminatory practices in daily life (everyday racism) and six questions on ever experiencing unfair treatment in key institutional contexts (lifetime racism). In 2015, the Insomnia Severity Index was used to assess insomnia symptoms. We estimated odds ratios and 95% confidence intervals for associations of racism with insomnia, using multivariable logistic regression models adjusted for potential confounders.

RESULTS

The 26 139 participants in the analytic sample were 40-90 years old (median = 57 years, SD = 9.6 years). Higher levels of everyday racism and lifetime racism were positively associated with subthreshold (ptrend < .01) and clinical insomnia (ptrend < .01). Results remained unchanged after further adjustment for sleep duration and shift work.

CONCLUSIONS

Higher levels of perceived racism were associated with increased odds of insomnia among middle-aged and elderly Black women. Thus, perceived racism may contribute to multiple racial health disparities resulting from insomnia. Helping minority populations cope with their experiences of discrimination may decrease the significant public health impact of sleep disruption and subsequent diagnoses.

The role of biocultural approaches in assessing interventions for maternal weight and gestational weight gain

Public health and other researchers express growing concern for the role of maternal adiposity and gestational weight gain in driving the obesity epidemic and health disparities based on race and class. Biocultural scholars must continue to contribute to conversations on how best to address issues of population health including the developmental context of obesity, drawing from both evolutionary and social theory. I discuss a number of intervention studies designed to address gestational weight gain in low-income and minority women and consider the degree to which they address the social, political, and economic context, and developmental history of mothers. I further examine the potential for these interventions, focused on the individual behavior of mothers, to contribute to stigma based on socially defined race, class, and body shape and size, and to draw attention away from the powerful economic interests that contribute to and benefit from the obesity epidemic. I end with a discussion of the value of developmental systems theory for thinking critically about obesity and other health interventions.

The Path to Better Health for Black Women: Predicting Self-Care and Exploring Its Mediating Effects on Stress and Health

Stress leads to poor self-rated health for many black women because of racial and economic discrimination which results in psychological distress and restricted access to resources. Resilience factors such as self-care may be able to buffer the impact of stress; however, the role of self-care in reducing the effect of stress on self-rated health has not been explored. Self-care involves the utilization of self-awareness and agency to seek remedy for imbalance and to sustain equilibrium. Despite anecdotal exploration of these factors, there has not been a systematic investigation of whether self-awareness and agency indeed predict self-care. Subsequently, this study sought to provide evidence that self-awareness and resilience predict self-care, and self-care can mediate the negative relationship between stress and self-rated health. A cross-section of 223 black women living in the United States completed a battery of assessments of self-care, mindfulness, perceived stress, resilience, and self-rated health. Through a series of regression analyses exploring mediating effects, a path emerged. Findings indicate that awareness and resilience do predict self-care, and self-care mediates the negative relationship between stress and health. These analyses suggest that the role of stress on black women’s health can be reduced by the implementation of awareness and resilience.

Perceived racism in relation to telomere length among African American women in the Black Women's Health Study

PURPOSE

Telomere length is considered a biomarker of human aging and premature morbidity and mortality which has been associated with chronic stress.

METHODS

We assessed the relation between perceived racism and telomere length in the Black Women's Health Study, a follow-up study of U.S. black women begun in 1995. Participants were asked about frequency of "everyday racism" (e.g., "people act as if they think you are not intelligent") and "institutional racism" (e.g., "ever treated unfairly due to race by police"). Using quantitative real-time polymerase chain reaction assay, relative telomere lengths (RTL) were measured as the copy number ratio of telomere repeat to a single control gene in 997 participants. Associations of racism variables with log-RTL were estimated by multivariable linear regression, with adjustment for age at blood draw and potential confounders.

RESULTS

Participants were aged 40-70 years (mean = 55.6 years), and mean telomere length was 0.77 (range 0.21-1.38). In stratified analyses, there was an inverse association between everyday racism and log-RTL among women who did not discuss their experiences of racism with others (β = -0.1104; 95% CI = -0.2140 to -0.0067; P = .045).

CONCLUSIONS

Everyday racism was associated with shorter telomere length among women who reported not discussing those experiences with others.

The role of emotional eating in the links between racial discrimination and physical and mental health

The environmental affordances (EA) model posits that maladaptive self-regulatory strategies (e.g., emotional eating) directly and indirectly heighten African Americans' risk for downstream medical morbidities while also potentially mitigating the psychological impact of stressors. We empirically tested the full EA model. In doing so, we investigated the associations among racial discrimination, depressive symptomatology, and physical health proxies as well as the intervening role of emotional eating in these associations among 150 African Americans aged 18-27. The increased frequency of experiencing racial discrimination was significantly associated with poorer self-reported health, greater depressive symptomatology, and more emotional eating. There was no significant association between emotional eating and physical health and emotional eating did not mediate the relation between racial discrimination and physical health. Finally, racial discrimination was associated with depressive symptomatology, but only among African Americans with mean or high levels of emotional eating.

Parent-Perceived Stress and Its Association With Children's Weight and Obesity-Related Behaviors

Introduction

Psychosocial stress is associated with obesity in adult and pediatric populations, but few studies have examined the relationship between parent-perceived stress and risk of child obesity and related behaviors.

Methods

We studied 689 pairs of parents and children aged 2 to 12 in Massachusetts with a body mass index (BMI) at or above the 85th percentile. Recruitment occurred from June 2014 to March 2015, and data collection ended in March 2016. We asked parents about their perceived stress and categorized responses as low, moderate, or high. We examined associations of parents’ stress with children’s BMI, expressed as a percentage of the 95th percentile (%BMIp95), and obesity-related behaviors by using multivariable regression models adjusted for child and parent characteristics. We stratified results by race/ethnicity, annual household income, and the child’s age.

Results

In fully adjusted models, the association between high versus low parent-reported stress and children’s %BMIp95 remained significant only for children in low-income households (β = 5.12; 95% confidence interval [CI], 0.94–9.30) and for non-Hispanic black children (β = 7.76; 95% CI, 1.85–13.66). Parents with high or moderate stress versus low stress were less likely to report that their children met recommendations for fast-food consumption (high stress, prevalence ratio [PR] = 0.79; 95% CI, 0.65–0.96; moderate stress, PR = 0.70; 95% CI, 0.59–0.82), but parents with high versus low stress were more likely to report meeting daily physical activity recommendations (PR = 1.21; 95% CI, 1.01–1.45).

Conclusion

Among children with overweight or obesity, parent-perceived stress was associated with fast-food consumption and physical activity. Parent-perceived stress was associated with child %BMIp95 among children in low-income households and non-Hispanic black children. Obesity interventions should consider parent-perceived stress and potential differences in the nature of stress experienced by parents of different racial/ethnic and socioeconomic backgrounds.

Racial Discrimination and Low Household Education Predict Higher Body Mass Index in African American Youth

OBJECTIVE

The purpose of this study was to examine the relationships between environmental factors, including household education, community violence exposure, racial discrimination, and cultural identity, and BMI in African American adolescents.

METHODS

A community-based sample of 198 African American youth (120 girls, 78 boys; ages 11-19 years) from Washtenaw County, Michigan, were included in this analysis. Violence exposure was assessed by using the Survey of Children's Exposure to Community Violence; racial discrimination by using the Adolescent Discrimination Distress Index; cultural identity by using the Acculturation, Habits, and Interests Multicultural Scale for Adolescents; and household education by using a seven-category variable. Measured height and body weight were used to calculate BMI.

RESULTS

Racial discrimination was positively associated with BMI, whereas household education was inversely associated with BMI in African American adolescents (discrimination: β = 0.11 ± 0.04, p = 0.01; education: β = -1.13 ± 0.47, p = 0.02). These relationships were significant when accounting for the confounding effects of stress, activity, diet, and pubertal development. Significant gender interactions were observed with racial discrimination and low household education associated with BMI in girls only (discrimination: β = 0.16 ± 0.05, p = 0.003; education: β = -1.12 ± 0.55, p = 0.045). There were no significant relationships between culture, community violence exposure, and BMI (all p's > 0.05).

CONCLUSION

Environmental factors, including racial discrimination and low household education, predicted higher BMI in African American adolescents, particularly among girls. Longitudinal studies are needed to better understand the mechanisms by which these environmental factors increase obesity risk in African American youth.

An association between multiculturalism and psychological distress

Amidst increasing focus on rising rates of substance abuse and suicide among white Americans and extending prior research on intergroup attitudes and health, this study examines a novel factor associated with psychological distress: disagreement with multiculturalism. Using the Portraits of American Life Study (N = 2,292), logistic regressions indicate that for Whites and Hispanics, increased likelihood of psychological distress (depression, hopelessness and worthlessness) is associated with stronger disagreement with multiculturalism, measured as "If we want to create a society where people get along, we must recognize that each ethnic group has the right to maintain its own unique traditions." For Blacks, however, attitudes toward multiculturalism are not associated with psychological distress. Future research might determine if these results can be replicated, and if so, identify the causal mechanism(s) at work.

It Weigh(t)s on You: Everyday Discrimination and Adiposity Among Latinos

OBJECTIVE

Evidence suggests discrimination increases the risk of obesity. The biopsychosocial model of racism posits that psychological factors such as depressive symptoms may link experiences of perceived interpersonal discrimination to obesity. This study tested whether self-reported experiences of everyday discrimination were associated with adiposity indicators and whether depressive symptoms explained these associations.

METHODS

Cross-sectional survey data of 602 Latino adults living in Lawrence, Massachusetts, from the Latino Health and Well-being Project (2011-2013) were used. Participants completed questionnaires assessing perceived everyday discrimination and depressive symptoms. Anthropometric measures (i.e., BMI and waist circumference [WC]) were obtained by trained staff. Structural equation modeling was employed to test for direct and indirect effects of perceived everyday discrimination on adiposity.

RESULTS

Perceived everyday discrimination was directly and positively associated with higher BMI and WC, independent of sociodemographic factors, physical activity, and stressful life events. Perceived everyday discrimination was not indirectly associated with BMI and WC through depressive symptoms. However, perceived everyday discrimination was associated with higher levels of depressive symptoms.

CONCLUSIONS

Self-reported everyday discrimination among Latino adults is associated with adiposity. Day-to-day interpersonal discrimination may be implicated in obesity disparities for Latino adults.

Perceived discrimination and cardiovascular health disparities: a multisystem review and health neuroscience perspective

There are distinct racial disparities in cardiovascular disease (CVD) risk, with Black individuals at much greater risk than White individuals. Although many factors contribute to these disparities, recent attention has focused on the role of discrimination as a stress-related factor that contributes to racial disparities in CVD. As such, it is important to understand the mechanisms by which discrimination might affect CVD. Recent studies have examined these mechanisms by focusing on neurobiological mediators of CVD risk. Given this increase in studies, a systematic review of perceived discrimination and neurobiological mediators of CVD risk is warranted. Our review uses a multisystem approach to review studies on the relationship between perceived discrimination and (1) cardiovascular responses to stress, (2) hypothalamic-pituitary-adrenocortical axis function, and (3) the immune system, as well as (4) the brain systems thought to regulate these parameters of peripheral physiology. In addition to summarizing existing evidence, our review integrates these findings into a conceptual model describing multidirectional pathways linking perceived discrimination with a CVD risk.

Addressing the Social Determinants of Health: A Call to Action for School Nurses

Social determinants of health (SDOH), the conditions in which children are born, grow, live, work or attend school, and age, impact child health and contribute to health disparities. School nurses must consider these factors as part of their clinical practice because they significantly and directly influence child well-being. We provide clinical guidance for addressing the SDOH when caring for children with three common health problems (obesity, insufficient sleep, and asthma). Given their unique role as school-based clinical experts, care coordinators, and student advocates, school nurses are well suited to serve as leaders in addressing SDOH.

Chronic discrimination and bodily pain in a multiethnic cohort of midlife women in the Study of Women's Health Across the Nation

A growing literature links discrimination to key markers of biobehavioral health. While racial or ethnic differences in pain are seen in experimental and clinical studies, the authors were interested in how chronic discrimination contributes to pain within multiple racial or ethnic groups over time. Participants were 3056 African American, Caucasian, Chinese, Hispanic, and Japanese women from the Study of Women's Health Across the Nation. The Everyday Discrimination Scale was assessed from baseline through 13 follow-up examinations. The bodily pain subscale of the MOS 36-Item Short-Form Health Survey (SF-36) was assessed annually. There were large racial or ethnic differences in reports of discrimination and pain. Discrimination attributions also varied by race or ethnicity. In linear mixed model analyses, initially adjusted for age, education, and pain medications, chronic everyday discrimination was associated with more bodily pain in all ethnic groups (beta = -5.84; P < 0.002 for Japanese; beta = -6.17; P < 0.001 for African American; beta = -8.74; P < 0.001 for Chinese; beta = -10.54; P < 0.001 for Caucasians; beta = -12.82; P < 0.001 for Hispanic). Associations remained significant in all ethnic groups after adjusting for additional covariates in subsequent models until adding depressive symptoms as covariate; in the final fully-adjusted models, discrimination remained a significant predictor of pain for African American (beta = -4.50; P < 0.001), Chinese (beta = -6.62; P < 0.001), and Caucasian (beta = -7.86; P < 0.001) women. In this longitudinal study, experiences of everyday discrimination were strongly linked to reports of bodily pain for the majority of women. Further research is needed to determine if addressing psychosocial stressors, such as discrimination, with patients can enhance clinical management of pain symptoms.

Criminal Justice Contact, Stressors, and Obesity-Related Health Problems Among Black Adults in the USA

Criminal justice contact-defined as lifetime arrest, parole, or incarceration, seems to exacerbate chronic conditions, and those who are most likely to have had contact with the criminal justice system, such as Black adults, often already have pre-existing disproportionately high rates of stress and chronic conditions due to the social determinants of health that affect underrepresented minorities. Findings from this study suggest that there is a mechanism that links the stressors among Black adults manifested by such factors as family, financial, neighborhood, and personal problems with criminal justice contact to obesity-related health status. Using the National Survey of American Life (NSAL), modified Poisson regression analyses were used to determine the association between criminal justice contact, stressors, and obesity-related health problems among a national sample of Black adults (n = 5008). In the full model, the odds of experiencing obesity-related health problems for Black adults who had criminal justice contact was reduced (PR, 1.23 to 1.14) and not statistically significant. Black adults who reported experiencing family stressors (PR, 1.21; 95% CI, 1.08, 1.36), financial stressors (PR, 1.30; 95% CI, 1.16, 1.47), and personal stressors (PR, 1.16; 95% CI, 1.02, 1.31) were statistically significant and higher than those who reported not experiencing any of these stressors; neighborhood stressors was not statistically significant. The evidence suggests a relationship between the stressors associated with criminal justice contact and obesity-related health status. These findings emphasize the need to further explore the family, financial, and personal stressors for Black adults with criminal justice contact in order to further our understanding of their obesity-related health problems.ᅟ.

The weight of racism: Vigilance and racial inequalities in weight-related measures

In the United States, racial/ethnic inequalities in obesity are well-documented, particularly among women. Using the Chicago Community Adult Health Study, a probability-based sample in 2001-2003 (N = 3105), we examined the roles of discrimination and vigilance in racial inequalities in two weight-related measures, body mass index (BMI) and waist circumference (WC), viewed through a cultural racism lens. Cultural racism creates a social environment in which Black Americans bear the stigma burden of their racial group while White Americans are allowed to view themselves as individuals. We propose that in this context, interpersonal discrimination holds a different meaning for Blacks and Whites, while vigilance captures the coping style for Blacks who carry the stigma burden of the racial group. By placing discrimination and vigilance within the context of cultural racism, we operationalize existing survey measures and utilize statistical models to clarify the ambiguous associations between discrimination and weight-related inequalities in the extant literature. Multivariate models were estimated for BMI and WC separately and were stratified by gender. Black women had higher mean BMI and WC than any other group, as well as highest levels of vigilance. White women did not show an association between vigilance and WC but did show a strong positive association between discrimination and WC. Conversely, Black women displayed an association between vigilance and WC, but not between discrimination and WC. These results demonstrate that vigilance and discrimination may hold different meanings for obesity by ethnoracial group that are concealed when all women are examined together and viewed without considering a cultural racism lens.

Perceptions of general and postpresidential election discrimination are associated with loss of control eating among racially/ethnically diverse young men

OBJECTIVE

The purpose of this study was to examine the association between young men's perceived experiences with discrimination, both general and following the 2016 presidential election, and their loss of control (LOC) eating. The degree to which men identified with their ethnic identity was evaluated as a moderator.

METHOD

The sample included 798 men (18-30 years; M = 24.0 ± 3.6) who identified as African American (n = 261), Asian/Asian American (n = 266), or Hispanic/Latino (n = 271). Participants completed an online survey of items assessing demographic characteristics; perceived discrimination; perceptions of race-related discrimination following the 2016 U.S. presidential election; ethnic identity; and LOC eating.

RESULTS

After adjusting for income, education, generational status and body mass index, perceived discrimination was positively associated with LOC eating frequency in African American and Hispanic/Latino men (ps < .01). Ethnic identity was inversely associated with LOC eating frequency in Hispanic/Latino men (p < .001). In Asian/Asian American men, perceived discrimination was only associated with more LOC eating among those with a low ethnic identity (p < .001). Higher levels of perceived discrimination following the presidential election were uniquely associated with more frequent LOC eating (p < .01) only among Asian/Asian American men who were not born in the United States or whose parents were not born in the United States.

DISCUSSION

LOC eating may partially explain known associations between discrimination and heightened risk for obesity and chronic diseases among African American and Hispanic/Latino men. Asian/Asian American men's LOC eating may be linked to postpresidential election and general experiences with racial discrimination, particularly if they report a low sense of belonging to their ethnic group.

Perceived racism and incident diabetes in the Black Women's Health Study

AIMS/HYPOTHESIS

Our aim was to assess the association of perceived racism with type 2 diabetes, and the possible mediating influence of diet and BMI.

METHODS

The Black Women's Health Study, a follow-up of 59,000 African-American women, began in 1995. Over 16 years 5344 incident cases of diabetes occurred during 576,577 person-years. Cox proportional hazards models were used to estimated HRs and 95% CIs for categories of 'everyday racism' (interpersonal racism in daily life) and 'lifetime racism' (reporting ever treated unfairly due to race with respect to police, housing or work) and incident type 2 diabetes. Models were adjusted for age, questionnaire cycle, marital status, socioeconomic status, education, family history of diabetes, physical activity, alcohol use and smoking status, with and without inclusion of terms for dietary patterns and adult BMI.

RESULTS

Compared with women in the lowest quartile of exposure, women in the highest quartile of exposure to everyday racism had a 31% increased risk of diabetes (HR 1.31; 95% CI 1.20, 1.42) and women with the highest exposure to lifetime racism had a 16% increased risk (HR 1.16; 95% CI 1.05, 1.27). Mediation analysis estimated that BMI accounted for half of the association between either the everyday or lifetime racism measure and incident diabetes.

CONCLUSIONS/INTERPRETATION

Perceived everyday and lifetime racism were associated with increased risk of type 2 diabetes in this cohort of African-American women and appear to be at least partly mediated by BMI.
