Abstract
We reviewed research that examines racism as an independent variable and one or more health outcomes as dependent variables in Black American adults aged 50 years and older in the USA. Of the 43 studies we reviewed, most measured perceived interpersonal racism, perceived institutional racism, or residential segregation. The only two measures of structural racism were birth and residence in a "Jim Crow state." Fourteen studies found associations between racism and mental health outcomes, five with cardiovascular outcomes, seven with cognition, two with physical function, two with telomere length, and five with general health/other health outcomes. Ten studies found no significant associations in older Black adults. All but six of the studies were cross-sectional. Research to understand the extent of structural and multilevel racism as a social determinant of health and the impact on older adults specifically is needed. Improved measurement tools could help address this gap in science.

Associations between social determinants of health, perceived discrimination, and body mass index on symptoms of depression among young African American mothers. Arch Psychiatr Nurs 2021; 35:94-101. [PMID: 33593522 PMCID: PMC7890049 DOI: 10.1016/j.apnu.2020.09.014] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2019] [Revised: 04/09/2020] [Accepted: 09/12/2020] [Indexed: 10/22/2022]
Abstract
PURPOSE The association between symptoms of depression and risks for cardiovascular disease (CVD) remains equivocal for African American (AA) mothers. We examined the association between social determinants of health (perceived discrimination), and cardiovascular risk (BMI) on symptoms of depression in a sample of young AA mothers. METHODS Secondary data from 219 adult AA mothers between the ages of 21 and 46 with an average BMI of 29.8 and yearly family income of $14,999 were analyzed using a latent growth model that evaluated four time points to assess changes in symptoms of depression. RESULTS Initial BMI was significantly associated with initial symptoms of depression (b = 0.12, p = .019). Perceived discrimination (unfair treatment) was associated with higher initial symptoms of depression (b = 1.14, p = .017). CONCLUSION The findings suggest that elevated BMI and perceived discrimination are associated with higher reported symptoms of depression among young, socioeconomically disadvantaged AA mothers. These results advance the scientific understanding of young AA mothers' risk for symptoms of depression and CVD by elucidating the impact of perceived discrimination and social experiences on mental health. Further studies of SDoH and CVD risk factors and perceived racism and depression are needed to shed light on the long-term mental health impact on AA mothers and their children.

Brain Sci 2020; 10:brainsci10100703. [PMID: 33022949 PMCID: PMC7600639 DOI: 10.3390/brainsci10100703] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Accepted: 10/02/2020] [Indexed: 12/18/2022] Open
Abstract
Background: Nucleus accumbens (NAc) is a brain structure with a well-established role in the brain reward processing system. Altered function of the NAc is shown to have a role in the development of food addiction and obesity. However, less is known about sex differences in the role of NAc function as a predictor of children’s change in body mass index (BMI) over time. Aim: We used the Adolescent Brain Cognitive Development data (version 2.01) to investigate sex differences in the predictive role of the NAc functional connectivity with the frontoparietal network on children’s BMI change over a one-year follow-up period. Methods: This 1-year longitudinal study successfully followed 3784 9–10-year-old children. Regression models were used to analyze the data. The predictor variable was NAc functional connectivity with the frontoparietal network measured using resting-state functional magnetic resonance imaging (fMRI). The primary outcome was BMI at the end of the 1-year follow up. Covariates included race, ethnicity, age, socioeconomic factors, and baseline BMI. Sex was the effect modifier. Results: NAc functional connectivity with the frontoparietal network was predictive of BMI changes over time. This association remained significant above and beyond all covariates. The above association, however, was only significant in female, not male children. Conclusion: The epidemiological observation that NAc functional connectivity is associated with BMI changes in children is an extension of well-controlled laboratory studies that have established the role of the NAc in the brain reward processing. More research is needed on sex differences in the brain regions that contribute to childhood obesity.

Assari S. Prostate Cancer Screening in Middle-Aged and Older American Men: Combined Effects of Ethnicity and Years of Schooling. HOSPITAL PRACTICES AND RESEARCH 2020; 5:64-69. [PMID: 32783022 PMCID: PMC7416895] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 06/11/2023] Open
Abstract
BACKGROUND Prostate cancer screening is more commonly utilized by highly educated people. As shown by marginalization-related diminished returns (MDRs), the effects of socioeconomic status (SES) such as education on the health outcomes are considerably smaller for ethnic minorities than for Whites. The role of MDRs as a source of ethnic health disparities is, however, still unknown. OBJECTIVES The current study had two aims: first, to explore the association between years of schooling and having taken a prostate-specific antigen (PSA) test among men in the US, and second, to explore ethnic differences in this association. METHODS This study was a secondary analysis of data from the National Health Interview Survey (NHIS-2015). The data of 5,053 men aged 55 years or older who were either Latino, non-Latino, African-American, or White were analyzed. Years of schooling was the independent variable. The dependent variable was taking a PSA test sometime during one's lifetime. Age, region, and employment were the control variables. Ethnicity was the focal moderating variable. Binary logistic regression was used for data analysis. RESULTS A higher number of years of schooling was associated with higher odds of having taken a PSA test, net of all confounders. Ethnicity showed a significant statistical interaction with years of schooling on having taken a PSA test. This interaction was suggestive of a smaller slope for Latino men than non-Latino men. White and African American men did not show differential effects of years of schooling on having taken a PSA test. CONCLUSION Similar to the MDRs patterns in other domains, non-Latino White men show more health gain from their years of schooling than Latino men. Highly educated Latino men still need programs to encourage their use of prostate cancer screening.

Abstract
Background The literature on Minorities' Diminished Returns (MDRs) have shown worse than expected health of the members of racial and ethnic minority groups particularly Blacks. Theoretically, this effect can be in part due to weaker effects of educational attainment on preventive care and disease management in highly educated racial and ethnic minorities. Objectives The current study explored the racial and ethnic differences in the effect of baseline educational attainment on % adherance to the routine physician visits among middle-aged and older adults in the US. Methods This is a prospective study with 24 years of follow up. The Health and Retirement Study (HRS: 1992-2016) included 10 880 middle-aged and older adults who were Hispanic, non-Hispanic, Black or White. The independent variable was educational attainment. The dependent variable was adherance to the routine physician visits (%). Age, gender, marital status, income, health behaviors (smoking and drinking) and health (depression, self-rated health, and chronic diseases) were the covariates. Race and ethnicity were the focal moderators. Linear regression was used for data analysis. Results Overall, higher educational attainment was associated with higher % of adherance to the routine physician visits over the course of follow-up, net of all confounders. Race showed a significant statistical interaction with educational attainment suggesting of a smaller effect of high education attainment on % adherance to the routine physician visits for Black than White middle-aged and older adults. A similar interaction could not be found for the comparison of Hispanic and non-Hispanic middle-aged and older adults. Conclusion Educational attainment is associated with a larger increase in preventive and disease management doctor visits for White than Black middle-aged and older adults. This is a missed opportunity to improve the health of highly educated middle-aged and older adults. It is not race/ethnicity or class that shapes health behaviors but race/ethnicity and class that shape people's pro-health behaviors. At least some of the racial health disparities is not due to low SES but diminished returns of SES.

Abstract
Background The Minorities' Diminished Returns (MDRs) theory suggests that the health effect of educational attainment is considerably smaller for members of racial and ethnic minority groups than for Whites. Objective The current study explored the racial and ethnic differences in the association between educational attainment and breast physical exam (BPE) among women in the U.S. Methods The National Health Interview Survey (NHIS 2015) included 12 510 women who were Hispanic or non-Hispanic Black or White people. The independent variable was the level of educational attainment. The dependent variable was lifetime BPE. Age, region, marital status, and employment were the covariates. Race and ethnicity were the focal moderators. Logistic regressions were used for data analysis. Results Overall, higher educational attainment was associated with higher odds of BPE, net of all confounders (odds ratio [OR] = 1.11, 95% CI = 1.09-1.13). Ethnicity showed a significant statistical interaction with educational attainment on BPE (OR = 0.96, 95% CI = 0.93-1.00), which was suggestive of a smaller effect of high education attainment on BPE for Hispanic than non-Hispanic women. The same interaction could not be found for the comparison of White and Black women (OR = 0.98, 95% CI =0.94-1.02). Conclusion In line with other domains, non-Hispanic White women show a larger amount of health gain from their educational attainment than Hispanic women. It is not ethnicity or class but ethnicity and class that shapes how people engage in pro-health behaviors. This result may help hospitals and healthcare systems to better reduce health disparities in their target populations.

Abstract
Background Considerable research has documented the effects of race and socioeconomic status (SES) on reward-seeking behaviors; however, less is known about the multiplicative effects of race and family SES on brain response to reward anticipation. Marginalization-related Diminished Returns (MDRs) suggest that family SES would show weaker effects on brain development of children in non-White families than in White families. Objective To test race by SES variation in Nucleus Accumbens (NAcc) response to reward anticipation (NAcc-RA) among American children. Methods For this cross-sectional analysis, data came from the Adolescent Brain Cognitive Development (ABCD) study which included 6,419, 9-10 year old children. The independent variable was parental education. The moderator was race. The primary outcome was the right NAcc-RA. Age, sex, ethnicity, household income, and family structure were the covariates. We used mixed effects regression models that adjusted for the nested nature of the ABCD data. Results While high parental education was associated with a higher amount of right NAcc-RA, this effect was stronger for White than non-White children. This finding was evident in the observed interactions between race and parental education on the right NAcc-RA. Discussion For American children, NAcc-RA is not shaped by race or family SES, but by their intersection. As a result of the interaction between race and SES (diminished return of SES for non-Whites), middle-class racial minority children may remain susceptible to high-risk behaviors. Disparities in high-risk behaviors in children should not be reduced to economic disparities. Structural inequalities may reduce the return of SES resources for non-White families.

Abstract
Background Socioeconomic status (SES) is associated with several health-related outcomes, such as obesity and body mass index (BMI). However, we do not know whether SES is associated differently with children's BMI from American Indian and Alaska Native and Native Hawaiian and Pacific Islander (AIAN/NHPI) families when compared to non-Hispanic White (NHW) families. Aim To compare AIAN/NHPI and NHW families for associations between parental education, family income, and children's BMI in the United States (U.S). Methods This cross-sectional investigation used the Adolescent Brain Cognitive Development (ABCD) study data. Participants (n = 8580) included 63 AIAN/NHPI and 8517 NHW children between ages 9 and 10. The independent variables were parental education and family income. The primary outcome was BMI. Race was the moderator. Age, sex, and family structure were covariates. Mixed-effects regression models were used for data analysis. Results In the pooled sample, higher parental education and family income were associated with lower children's BMI. We found interactions between race and parental education and family income indicating weaker associations between parental education and family income and children's BMI in AIAN/NHPI families than in NHW families. Conclusion The salience of parental education and family income as social determinants of children's BMI is diminished for AIAN/NHPI families than NHW families. As a result, AIAN/NHPI children with high SES remain at risk for high BMI, while high-SES NHW children show the lowest BMI. Future research should test if obesogenic environments, food options, and physical activity-friendly neighborhoods can explain higher-than-expected BMI in high-SES AIAN/NHPI children. In other terms, more research is needed to understand if residential segregation, discrimination, and historical trauma explain the observed differences in the social patterning of childhood BMI in AIAN/NHPI and NHW communities.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:E3705.

Abstract
Background: Although obesity may have a role as a risk factor for cerebrovascular mortality, less is known about how demographic and social groups differ in this regard. Aims: This study had two aims: first to investigate the predictive role of baseline obesity on long-term risk of mortality due to cerebrovascular disease, and second, to test racial variation in this effect. Methods: the Americans' Changing Lives Study (ACL) 1986-2011 is a state of the art 25-year longitudinal cohort study. ACL followed a nationally representative sample of Blacks (n = 1156) and Whites (n = 2205) for up to 25 years. Baseline obesity was the main predictor of interest, time to cerebrovascular death was the main outcome of interest. Demographic characteristics, socioeconomic status (educational attainment and household income), health behaviors (exercise and smoking), and health (hypertension and depressive symptoms) at baseline were covariates. Cox proportional hazards models were used to test additive and multiplicative effects of obesity and race on the outcome. Results: From the total 3,361 individuals, 177 people died due to cerebrovascular causes (Whites and Blacks). In the pooled sample, baseline obesity did not predict cerebrovascular mortality (hazard ratio (HR) = 0.86, 0.49-1.51), independent of demographic, socioeconomic, health behaviors, and health factors at baseline. Race also interacted with baseline obesity on outcome (HR = 3.17, 1.09-9.21), suggesting a stronger predictive role of baseline obesity on cerebrovascular deaths for Black people compared to White individuals. According to the models that were run specific to each race, obesity predicted risk of cerebrovascular mortality for Blacks (HR = 2.51, 1.43-4.39) but not Whites (HR = 0.69, 0.31-1.53). Conclusions: Baseline obesity better predicts long-term risk of cerebrovascular death in Black individuals compared to White people. More research should explore factors that explain why racial differences exist in the effects of obesity on cerebrovascular outcome. Findings also have implications for personalized medicine.

Abstract
BACKGROUND Minorities' Diminished Returns (MDRs) refer to smaller protects health effects of socioeconomic status (SES) indicators for Blacks and other minority groups than Whites. OBJECTIVES The current study aimed to explore Black- White differences in the association between educational attainment and exercise frequency among women in the US. METHODS For the current study, we used the National Survey of American Life's (NSAL) data which included 3,175 women who were either White (n = 876) or Black (n = 2,299). The independent variable was educational attainment. The dependent variable was exercise frequency. Age, region, household income, financial distress, marital status, unemployment, and depression were the covariates. Race was the focal moderator. Linear regression was applied for data analysis. RESULTS In the overall sample of women, high educational attainment was associated with higher exercise frequency (b = 0.07, 95% CI = 0.02-0.12). Race and educational attainment showed a significant interaction (b = -0.09, 95% CI = -0.19-0.00), suggestive of a smaller effect of education attainment on exercise frequency for Black women than White women. In race specific models, high educational attainment was associated with higher exercise frequency for White (b = 0.12, 95% CI =0.04-0.20) but not Black (b = 0.03, 95% CI = -0.03-0.08) women. CONCLUSION In line with the past research on MDRs, White women gain more health from their educational attainment than Black women. It is not race or class but race and class that shape the health behaviors of American women.

Abstract
Despite high prevalence of obesity and polypharmacy among African American (AA) older adults, little information exists on the associations between the two in this population. This study explored the association between obesity and polypharmacy among AA older adults who were residing in poor urban areas of South Los Angeles. We also investigated role of gender as the moderator and multimorbidity as the mediator of this association. In a community-based study in South Los Angeles, 308 AA older adults (age ≥ 55 years) were entered into this study. From this number, 112 (36.4%) were AA men and 196 (63.6%) were AA women. Polypharmacy (taking 5+ medications) was the dependent variable, obesity was the independent variable, gender was the moderator, and multimorbidity (number of chronic medical conditions) was the mediator. Age, educational attainment, financial difficulty (difficulty paying bills, etc.), income, marital status, self-rated health (SRH), and depression were the covariates. Logistic regressions were used for data analyses. In the absence of multimorbidity in the model, obesity was associated with higher odds of polypharmacy in the pooled sample. This association was not significant when we controlled for multimorbidity, suggesting that multimorbidity mediates the obesity-polypharmacy link. We found significant association between obesity and polypharmacy in AA women not AA men, suggesting that gender moderates such association. AA older women with obesity are at a higher risk of polypharmacy, an association which is mainly due to multimorbidity. There is a need for screening for inappropriate polypharmacy in AA older women with obesity and associated multimorbidity.

Abstract
Background. Despite the prevalence of multimorbidity among African American (AA) older adults, little information exists on correlates of polypharmacy (using 5+ medications) in AA older adults. There is more information available regarding the link between polypharmacy and physical aspects of health than subjective ones. Aims. In a local sample of AA older adults in Los Angeles, this study investigated the association of polypharmacy with self-rated health (SRH) and depression. We also explored gender differences in these links. Methods. This community-based study was conducted in south Los Angeles. A total number of 708 AA older adults (age ≥ 55 years) were entered into this study. From this number, 253 were AA men and 455 were AA women. Polypharmacy was the independent variable. Self-rated health (SRH) and depression were the dependent variables. Age, educational attainment, financial difficulty (difficulty paying bills, etc.), and marital status were covariates. Gender was the moderator. Multimorbidity, measured as the number of chronic diseases (CDs), was the mediator. Logistic regressions were applied for data analysis. Results. Polypharmacy was associated with worse SRH and depression. Multimorbidity fully mediated the association between polypharmacy and depressive symptoms. Multimorbidity only partially mediated the association between polypharmacy and poor SRH. Gender moderated the association between polypharmacy and SRH, as polypharmacy was associated with poor SRH in women but not men. Gender did not alter the association between polypharmacy and depression. Conclusions. AA older women with polypharmacy experience worse SRH and depression, an association which is partially due to the underlying multimorbidity. There is a need for preventing inappropriate polypharmacy in AA older adults, particularly when addressing poor SRH and depression in AA older women with multimorbidity.

Chalian H, Khoshpouri P, Assari S. Patients' age and discussion with doctors about lung cancer screening; Diminished returns of Blacks. Aging Med (Milton) 2019; 2:35-41. [PMID: 31179418 PMCID: PMC6553649 DOI: 10.1002/agm2.12053] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2018] [Revised: 01/27/2019] [Accepted: 01/30/2019] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND As age is one of the main risk factors for lung cancer, older adults are expected to receive more messages for lung cancer screening (LCS). It is, however, unclear whether age similarly increases patient's chance of discussing LCS across various racial groups. OBJECTIVE To determine racial differences in the effect of patients' age on patient-physician discussion about LCS. METHODS This cross-sectional study borrowed data from the Health Information National Trends Survey (HINTS 2017) which included 2,277 adults. Patients' demographic factors, socioeconomic characteristics, smoking status, possible LCS indication, and patient-physician discussion about LCS were measured. We ran logistic regression models for data analysis. RESULTS Independent of possible LCS indication, older patients were more likely to have patient-physician discussion about LCS. However, there is a significant interaction between race and age, suggesting a larger effect of age on the likelihood of discussing LCS with doctors for Whites than Blacks. In race-stratified models that controlled for possible LCS indication, higher age increased lung cancer discussion for Whites but not for Blacks. CONCLUSIONS Whether age increases the chance of discussing LCS or not depends on the patient's race, with Blacks receiving fewer messages regarding LCS as a result of their aging.

Abstract
Background: Although depression and financial distress are correlated, this association may differ for demographic groups, particularly based on race. Aim: Using a national sample of American adults, this study tested whether the association between Major Depressive Episode (MDE) and financial distress differs between African Americans and Whites. Methods: The National Survey of American Life (NSAL), 2003, enrolled 3570 African American and 891 Non-Hispanic White American adults. Demographic data (age and gender), socioeconomic position (SEP; i.e., education, employment, marital status, and income), financial distress, and 12-month MDE were measured. Logistic regression was used for data analysis. Results: In the pooled sample, 12-month MDE was associated with higher odds of financial distress, above and beyond objective SEP measures. We found MDE by race interaction on financial distress, suggesting stronger association between MDE and financial distress among African Americans, compared to Whites. Conclusions: The link between MDE and financial distress depends on race. The financial needs of African Americans with depression should be addressed. Depression screening is also needed for African Americans with financial distress.

Abstract
Background: Although obesity and depression have a bidirectional association, this link may vary based on race. The current study tested racial variation in bidirectional links between depressive symptoms and body mass index (BMI) over 24 years of follow-up in older adults over the age of 50 in the United States. We hypothesized weaker bidirectional links in Blacks compared to Whites. Methods: Data came from waves 1 to 12 (1990 to 2014) of the Health and Retirement Study (HRS), an ongoing state-of-the-art national cohort. The study followed a representative sample of Americans (n = 15,194; 2,200 Blacks and 12,994 Whites) over the age of 50. Dependent variables were average depressive symptoms and BMI over 24 years, based on measurements every other year, from 1990 to 2014. Independent variables included baseline depressive symptoms and BMI. Covariates included age, gender, marital status, veteran status, and activities of daily living. Structural equation models were fitted to the data for data analysis. Results: In the pooled sample, bidirectional associations were found between BMI and depressive symptoms as baseline BMI predicted average depressive symptoms over time and baseline depressive symptoms predicted average BMI over 24 years. Racial differences were found in the bidirectional association between BMI and depressive symptoms, with both directions of the associations being absent for Blacks. For Whites, baseline BMI predicted average depressive symptoms over the next 24 years. Conclusion: Reciprocal associations between BMI and depressive symptoms over a 24-year period among individuals over the age of 50 vary for Blacks and Whites. As these associations are stronger for Whites than Blacks, clinical and public health programs that simultaneously target comorbid obesity and depression may be more appropriate for Whites than Blacks.

Abstract
BACKGROUND Perceived discrimination has been associated with cigarette smoking and other substance use among members of disadvantaged minority groups. However, most studies have focused on a single minority group, have not considered the individual's attribution for the discrimination, and have not considered emerging tobacco products. OBJECTIVE This study examined the associations between perceived discrimination and use of six tobacco products (cigarettes, e-cigarettes, cigars, pipe tobacco, hookah, and smokeless tobacco) in a diverse sample of 1,068 adults in the United States. METHODS Participants were recruited on Amazon's Mechanical Turk and participated in an online survey. Logistic regression models were used to examine the association between perceived discrimination and use of each tobacco product. Interactions between discrimination and demographic characteristics, and between discrimination and perceived reasons for discrimination, were evaluated. RESULTS Controlling for age, sex, race/ethnicity, education, and socioeconomic status, perceived discrimination was a risk factor for current use of five of the six tobacco products. These associations were consistent across racial/ethnic groups and regardless of the individual's attribution for the reason for the discrimination. CONCLUSIONS Results indicate that perceived discrimination is a risk factor for the use of multiple tobacco products, and that this association is not limited to particular demographic groups or types of discrimination. Public health programs could potentially reduce tobacco-related disease by teaching healthier ways to cope with discrimination.

Assari S, Moghani Lankarani M. Workplace Racial Composition Explains High Perceived Discrimination of High Socioeconomic Status African American Men. Brain Sci 2018; 8:E139. [PMID: 30060492 PMCID: PMC6120025 DOI: 10.3390/brainsci8080139] [Citation(s) in RCA: 77] [Impact Index Per Article: 12.8] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2018] [Revised: 07/13/2018] [Accepted: 07/13/2018] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND Sociological and epidemiological literature have both shown that socioeconomic status (SES) protects populations and individuals against health problems. Recent research, however, has shown that African Americans gain less from their SES and African Americans of high SES, particularly males, may be vulnerable to perceived discrimination, as explained by the Minorities' Diminished Returns theory. One potential mechanism for this phenomenon is that high SES African Americans have a higher tendency to work in predominantly White workplaces, which increases their perceived discrimination. It is, however, unknown if the links between SES, working in predominantly White work groups and perceived discrimination differ for male and female African Americans. AIM To test the associations between SES, workplace racial composition and perceived discrimination in a nationally representative sample of male and female African American adults. METHODS This study included a total number of 1775 employed African American adults who were either male (n = 676) or female (n = 1099), all enrolled from the National Survey of American Life (NSAL). The study measured gender, age, SES (educational attainment and household income), workplace racial composition and perceived discrimination. Structural Equation Modeling (SEM) was applied in the overall sample and also by gender. RESULTS In the pooled sample that included both genders, high education and household income were associated with working in a predominantly White work group, which was in turn associated with more perceived discrimination. We did not find gender differences in the associations between SES, workplace racial composition and perceived discrimination. CONCLUSION Although racial composition of workplace may be a mechanism by which high SES increases discriminatory experiences for African Americans, males and females may not differ in this regard. Policies are needed to reduce discrimination in racially diverse workplaces. This is particularly the case for African Americans who work in predominantly White work environments.

Association between Actual and Perceived Obesity Weaker among Black than White Children. Behav Sci (Basel) 2018; 8:bs8050048.

Abstract
Although actual obesity is expected to be associated with perceived overweight, some recent studies in adults have suggested that this link may be smaller for Blacks than Whites. It is unknown, however, whether the same trend holds for children or not. This study explored the heterogeneity of the association between actual and perceived obesity in a national sample of American children by race, gender, and their intersection. Health Behavior in School-Aged Children (HBSC), 2009–2010, is a national study of children 17 years or less in the United States. This analysis included a total number of 8860 children, including 6581 (74.28%) White and 2279 (25.72%) Black children. Actual obesity, defined as a body mass index (BMI) greater than 95% of the age- and gender-percentile, was the independent variable. Perceived overweight was the main outcome. We ran linear regression models with and without interaction terms between race, gender, and actual obesity. We also ran race- and gender-specific linear regression models. In the pooled sample, actual obesity was positively associated with perceived overweight. We found an interaction between race and obesity, suggesting stronger association between actual obesity and perceived overweight for White than Black children. Gender or intersection of race and gender did not alter the association between actual obesity and perceived overweight. The link between actual obesity and perceived overweight depends on race of the child. Inaccurately perceived weight may be one of many mechanisms behind the disproportionately higher rate of obesity burden among Black children in the United States. As perceived overweight plays a salient role for weight control behaviors, Black children with obesity may need some help to perceive themselves as obese. Training programs should target Blacks to increase the accuracy of their weight and body size evaluation and perception as an essential step for reducing the burden of obesity among Black children.

Abstract
Background: Recent research has suggested vulnerability to perceived racial discrimination (PRD) as a mechanism behind high levels of depression seen in high socioeconomic status (SES) Black males. To better understand the effects of gender and SES on shaping experiences of PRD among Black youth in the United States, we used data from the Family and Community Health Study (FACHS) to explore the trajectory of PRD in Black youth by gender, SES, and place. Methods: Data came from FACHS, 1997⁻2017, which followed 889 children aged 10⁻12 years old at Wave 1 (n = 478; 53.8% females and n = 411; 46.2% males) for up to 18 years. Data were collected in seven waves. The main predictors of interest were gender, SES (parent education and annual family income), age, and place of residence. Main outcomes of interest were baseline and slope of PRD. Latent growth curve modeling (LGCM) was used for data analysis. Results: Gender, SES, place, and age were correlated with baseline and change in PRD over time. Male, high family income, and younger Black youth reported lower PRD at baseline but a larger increase in PRD over time. Youth who lived in Iowa (in a predominantly White area) reported higher PRD at baseline and also an increase in PRD over time. High parental education was not associated with baseline or change in PRD. Conclusion: In the United States, Black youth who are male, high income, and live in predominantly White areas experience an increase in PRD over time. Future research is needed on the interactions between gender, SES, and place on exposure and vulnerability of Black youth to PRD. Such research may explain the increased risk of depression in high SES Black males.

Abstract
Environmental stressors, such as perceived discrimination (PD), are linked to Binge Eating Disorder (BED). The current study investigated the association between PD and BED among African Americans, and the variation in such an association based on gender. Data of the National Survey of American Life (NSAL), 2001⁻2003, with a nationally-representative sample of African American adults, were used (n = 3516). The independent variable in the study was PD. The dependent variable was BED, measured using the Composite International Diagnostic Interview (CIDI). Socio-demographics (age, education, employment, and marital status) were covariates, and gender was the moderator variable. Survey logistic regressions with and without gender × PD interaction terms were used for data analysis. In the pooled sample, PD was associated with higher odds of BED, net of socio-demographic factors. Models also showed a significant gender × PD interaction term suggesting a stronger association between PD and BED for women, compared to men. Gender specific models showed an association between PD and BED among female, but not male, African Americans. Although a link may exist between PD and BED among African Americans, the magnitude of this association depends on gender, with a stronger association among females than males. This finding is in line with the literature that has shown gender-specific consequences of environmental stress for African Americans.

Abstract
The protective effect of family structure and socioeconomic status (SES) on physical and mental health is well established. There are reports, however, documenting a smaller return of SES among Blacks compared to Whites, also known as Blacks' diminished return. Using a national sample, this study investigated race by gender differences in the effects of family structure and family SES on subsequent body mass index (BMI) over a 15-year period. This 15-year longitudinal study used data from the Fragile Families and Child Wellbeing Study (FFCWS), in-home survey. This study followed 1781 youth from birth to age 15. The sample was composed of White males (n = 241, 13.5%), White females (n = 224, 12.6%), Black males (n = 667, 37.5%), and Black females (n = 649, 36.4%). Family structure and family SES (maternal education and income to need ratio) at birth were the independent variables. BMI at age 15 was the outcome. Race and gender were the moderators. Linear regression models were run in the pooled sample, in addition to race by gender groups. In the pooled sample, married parents, more maternal education, and income to need ratio were all protective against high BMI of youth at 15 years of age. Race interacted with family structure, maternal education, and income to need ratio on BMI, indicating smaller effects for Blacks compared to Whites. Gender did not interact with SES indicators on BMI. Race by gender stratified regressions showed the most consistent associations between family SES and future BMI for White females followed by White males. Family structure, maternal education, and income to need ratio were not associated with lower BMI in Black males or females. The health gain received from family economic resources over time is smaller for male and female Black youth than for male and female White youth. Equalizing access to economic resources may not be enough to eliminate health disparities in obesity. Policies should address qualitative differences in the lives of Whites and Blacks which result in diminished health returns with similar SES resources. Policies should address structural and societal barriers that hold Blacks against translation of their SES resources to health outcomes.

Abstract
The health effects of economic resources (eg, education, employment, and living place) and psychological assets (eg, self-efficacy, perceived control over life, anger control, and emotions) are well-known. This article summarizes the results of a growing body of evidence documenting Blacks' diminished return, defined as a systematically smaller health gain from economic resources and psychological assets for Blacks in comparison to Whites. Due to structural barriers that Blacks face in their daily lives, the very same resources and assets generate smaller health gain for Blacks compared to Whites. Even in the presence of equal access to resources and assets, such unequal health gain constantly generates a racial health gap between Blacks and Whites in the United States. In this paper, a number of public policies are recommended based on these findings. First and foremost, public policies should not merely focus on equalizing access to resources and assets, but also reduce the societal and structural barriers that hinder Blacks. Policy solutions should aim to reduce various manifestations of structural racism including but not limited to differential pay, residential segregation, lower quality of education, and crime in Black and urban communities. As income was not found to follow the same pattern demonstrated for other resources and assets (ie, income generated similar decline in risk of mortality for Whites and Blacks), policies that enforce equal income and increase minimum wage for marginalized populations are essential. Improving quality of education of youth and employability of young adults will enable Blacks to compete for high paying jobs. Policies that reduce racism and discrimination in the labor market are also needed. Without such policies, it will be very difficult, if not impossible, to eliminate the sustained racial health gap in the United States.

Abstract
OBJECTIVES To identify gender-specific associations between education and income in relation to obesity in developed countries by considering both the interaction-effect terms of the independent variables and their main-effect terms. DESIGN A cross-sectional study. Education and income levels were chosen as socioeconomic status indicators. Sociodemographics, lifestyles and medical conditions were used as covariates in multivariable logistic regression models. Adjusted ORs and predicted probabilities of being obese were computed and adjusted for a complex survey design. SETTING Data were obtained from the Fifth Korea National Health and Nutrition Examination Survey (2010-2012). PARTICIPANTS The sample included 7337 male and 9908 female participants aged ≥19 years. OUTCOME MEASURE Obesity was defined as body mass index of ≥25, according to a guideline for Asians. RESULTS In models with no interaction-effect terms of independent variables, education was significantly associated with obesity in both men and women, but income was significant only in women. However, in models with the interaction-effect terms, education was significant only in women, but income was significant only in men. The interaction effect between income and education was significant in men but not in women. Participants having the highest predicted probability of being obese over educational and income levels differed between the two types of models, and between men and women. A prediction using the models with the interaction-effect terms demonstrated that for all men, the highest level of formal education was associated with an increase in their probability of being obese by as much as 26%. CONCLUSIONS The well-known, negative association between socioeconomic status and obesity in developed countries may not be valid when interaction effects are included. Ignoring these effects and their gender differences may result in the targeting of wrong populations for reducing obesity prevalence and its resultant socioeconomic gradients.

Abstract
Background: This study aimed to investigate differences in the association between socioeconomic status (SES) and glycemic control in type 2 diabetes mellitus (DM) across race by gender groups. Methods: Using a convenient sampling strategy, participants were 112 patients with type 2 DM who were prescribed insulin (ns = 38 Black women, 34 Black men, 14 White women, and 26 White men, respectively). Linear regression was used to test the associations between sociodemographic variables (race, gender, SES, governmental insurance) and Hemoglobin A1c (HbA1c) in the pooled sample and within subgroups defined by race and gender. Results: In the pooled sample, neither SES nor governmental insurance were associated with HbA1c. However, the race by gender interaction approached statistical significance (B = 0.34, 95% CI = −0.24–3.00, p =0.094), suggesting higher HbA1c in Black women, compared to other race by gender groups. In stratified models, SES (B = −0.33, 95% CI = −0.10–0.00, p = 0.050), and governmental insurance (B = 0.35, 95% CI = 0.05–2.42, p = 0.042) were associated with HbA1c for Black men, but not for any of the other race by gender subgroups. Conclusion: Socioeconomic factors may relate to health outcomes differently across race by gender subgroups. In particular, SES may be uniquely important for glycemic control of Black men. Due to lack of generalizability of the findings, additional research is needed.

Whites but Not Blacks Gain Life Expectancy from Social Contacts. Behav Sci (Basel) 2017; 7:bs7040068. [PMID: 29035330 PMCID: PMC5746677 DOI: 10.3390/bs7040068] [Citation(s) in RCA: 37] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2017] [Revised: 08/31/2017] [Accepted: 09/14/2017] [Indexed: 11/16/2022] Open
Abstract
Background. Recent research suggests that the health gain from economic resources and psychological assets may be systematically larger for Whites than Blacks. Aim. This study aimed to assess whether the life expectancy gain associated with social contacts over a long follow up differs for Blacks and Whites. Methods. Data came from the Americans’ Changing Lives (ACL) Study, 1986–2011. The sample was a nationally representative sample of American adults 25 and older, who were followed for up to 25 years (n = 3361). Outcome was all-cause mortality. The main predictor was social contacts defined as number of regular visits with friends, relatives, and neighbors. Baseline demographics (age and gender), socioeconomic status (education, income, and employment), health behaviors (smoking and drinking), and health (chronic medical conditions, obesity, and depressive symptoms) were controlled. Race was the focal moderator. Cox proportional hazard models were used in the pooled sample and based on race. Results. More social contacts predicted higher life expectancy in the pooled sample. A significant interaction was found between race and social contacts, suggesting that the protective effect of more social contacts is smaller for Blacks than Whites. In stratified models, more social contacts predicted an increased life expectancy for Whites but not Blacks. Conclusion. Social contacts increase life expectancy for White but not Black Americans. This study introduces social contacts as another social resource that differentially affects health of Whites and Blacks.

Racial Discrimination in Health Care Is Associated with Worse Glycemic Control among Black Men but Not Black Women with Type 2 Diabetes. Front Public Health 2017; 5:235. [PMID: 28955703 PMCID: PMC5600936 DOI: 10.3389/fpubh.2017.00235] [Citation(s) in RCA: 30] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2017] [Accepted: 08/21/2017] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND A growing body of research suggests that racial discrimination may affect the health of Black men and Black women differently. AIMS This study examined Black patients with diabetes mellitus (DM) in order to test gender differences in (1) levels of perceived racial discrimination in health care and (2) how perceived discrimination relates to glycemic control. METHODS A total of 163 Black patients with type 2 DM (78 women and 85 men) provided data on demographics (age and gender), socioeconomic status, perceived racial discrimination in health care, self-rated health, and hemoglobin A1c (HbA1c). Data were analyzed using linear regression. RESULTS Black men reported more racial discrimination in health care than Black women. Although racial discrimination in health care was not significantly associated with HbA1c in the pooled sample (b = 0.20, 95% CI = -0.41 -0.80), gender-stratified analysis indicated an association between perceived discrimination and higher HbA1c levels for Black men (b = 0.86, 95% confidence intervals (CI) = 0.01-1.73) but not Black women (b = -0.31, 95% CI = -1.17 to -0.54). CONCLUSION Perceived racial discrimination in diabetes care may be more salient for glycemic control of Black men than Black women. Scholars and clinicians should take gender into account when considering the impacts of race-related discrimination experiences on health outcomes. Policies should reduce racial discrimination in the health care.

Abstract
AIM This study aimed to investigate gender differences in the association between baseline depressive symptoms and subsequent changes in obesity in a sample of urban Black youth in the USA. METHODS The current study followed 681 Black youth (335 male and 346 female) for up to 18 years from 1994 to 2012. All youth were selected from an economically disadvantaged urban area in MI, USA. The main independent variable was baseline depressive symptoms measured in 1994. The main outcome was change in body mass index (BMI) from 1999 to 2012, calculated based on self-reported height and weight. Scio-demographics (age, number of parents in the household, and parental employment) were covariates. Gender was the focal moderator. We used linear regressions to test the predictive role of baseline depressive symptoms on change in BMI (from 1999 to 2012) in the pooled sample, and also based on gender. RESULTS Among Black females, but not Black males, baseline depressive symptoms predicted the BMI change from 1999 to 2012. The association remained significant for Black females after controlling for covariates. CONCLUSION High depressive symptoms at baseline better predict BMI change over the next decade for female than male Black youth. As a result, detection and reduction of depressive symptoms may be a vital element of obesity prevention programs for Black females. Policies and programs that address determinants of psychological distress as a strategy to prevent obesity among female Black youth in disadvantaged neighborhoods may be especially useful.

Abstract
BACKGROUND The research on binge eating has overwhelmingly focused on Whites. We aimed to study gender and ethnic differences in the association between body image dissatisfaction and binge eating in a nationally representative sample of Black adults in the USA. METHODS This cross-sectional study used data from the National Survey of American Life (NSAL), 2003-2004. Self-identified Caribbean Black (n = 1621) and African American (3570) adults aged 18 and older were enrolled. The independent variable was body dissatisfaction measured with two items. Using the World Health Organization Composite International Diagnostic Interview (WHO-CIDI), outcome was lifetime binge eating without hierarchy according to the DSM-IV criteria. Covariates included age, socioeconomic factors (i.e., education and marital status), and body mass index. Ethnicity and gender were focal moderators. Logistic regressions were used for data analysis. RESULTS Despite comparable prevalence of lifetime binge eating (5 vs 4 %, p > 0.05), African Americans reported higher body image dissatisfaction than Caribbean Blacks (36 vs 29 %, p > 0.05). In the pooled sample, body dissatisfaction was a strong predictor of lifetime binge eating disorders. There was a significant interaction (p = 0.039) between ethnicity and body image dissatisfaction on binge eating, suggesting a stronger association between body image dissatisfaction and lifetime binge eating for Caribbean Blacks (OR = 11.65, 95 % 6.89-19.72) than African Americans (OR = 6.72, 95 % CI 3.97-11.37). Gender did not interact with body image dissatisfaction on binge eating. CONCLUSION Ethnic variation in the link between body image dissatisfaction and binge eating may be due to within-race cultural differences in body image between African Americans and Caribbean Blacks. This may include different definitions, norms, and expectations regarding the body size. Findings suggest that ethnicity may bias relevance of body image dissatisfaction as a diagnostic criterion for binge eating disorders among diverse populations of Blacks.

Abstract
Most studies on the role of family environment in developing risk of obesity among youth have focused on parenting behaviors that are directly involved in energy balance in regional, non-representative White samples. Using a national sample of ethnically diverse Black youth, the current study tested the association between low family support and risk of obesity. We also tested the heterogeneity of this association based on gender, ethnicity, and their intersection. We used data from the National Survey of American Life-Adolescent Supplement (NSAL-A), a national survey of Black adolescents in the United States. The study enrolled 1170 African American and Caribbean Black 13-17 year old youth. Obesity was defined based on the cutoff points of body mass index (BMI) appropriate for age and gender of youth. Family support was measured using a five-item measure that captured emotional and tangible social support. Age, gender, and ethnicity were also measured. Logistic regressions were utilized in the pooled sample, and also based on gender, ethnicity, and their intersection, to test the link between low family support and risk for obesity. RESULTS In the pooled sample, low family support was not associated with an increased risk of obesity (OR = 1.35, 95% Confidence Interval (CI) = 0.96-1.89). The association between low family support and risk of obesity was, however, significant among African American females (OR = 1.60, 95% CI = 1.01-2.55). There was no association for African American males (OR = 1.26, 95% CI = 0.82-1.92), Caribbean Black males (OR = 0.68, 95% CI = 0.01-54.85), and Caribbean Black females (OR = 0.78, 95% CI = 0.42-1.44). In conclusion, policies and programs that enable African American families to provide additional family support may prevent obesity among African American female youth. Future research should test the efficacy of promoting family support as a tool for preventing obesity among African American female youth.

Abstract
BACKGROUND Sleep and depression are comorbid problems that contribute to the development of chronic medical conditions (CMC) over time. Although racial and gender differences in the bidirectional associations between sleep, depression, and CMC are known, very limited information exists on heterogeneity of the residual effects of sleep problems over depressive symptoms on CMC across race by gender groups. AIM Using a life-course perspective, the present study compared race by gender groups for residual effects of restless sleep over depressive symptoms on CMC. METHODS We used data from waves 1 (year 1986), 4 (year 2001), and 5 (year 2011) of the Americans' Changing Lives Study (ACL). The study followed 294 White men, 108 Black men, 490 White women, and 237 Black women for 25 years. Restless sleep, depressive symptoms (Center for Epidemiological Studies-Depression scale [CES-D]), and number of chronic medical conditions (hypertension, diabetes, chronic lung disease, heart disease, stroke, cancer, and arthritis) were measured in 1986, 2001, and 2011. We employed multi-group cross-lagged modeling, with chronic medical conditions as the outcome and race by gender as the groups. RESULTS Major group differences were found in the residual effect of restless sleep on CMC over depressive symptoms across race by gender groups. Restless sleep in 2001 predicted CMC 10 years later in 2011 among Black women (standardized adjusted B = .135, P < .05) and White men (standardized adjusted = .145, P < .01) and White women (standardized adjusted B = .171, P < .001) but not Black men (standardized adjusted B = .001, P > .05). CONCLUSION Race by gender heterogeneity in the residual effect of restless sleep over depressive symptoms on CMC over 25 years suggests that comorbid poor sleep and depressive symptoms differently contribute to development of multi-morbidity among subpopulations based on the intersection of race and gender. Thus, interventions that try to prevent comorbid sleep problems and depression as a strategy to prevent medical conditions may benefit from tailoring based on the intersection of race and gender.

Abstract
BACKGROUND To examine associations of Body mass Index (BMI) and mental distress in late midlife in a large Danish community sample and to investigate the effect of socio-demographic factors. METHODS The study sample comprised 3613 Danish men and 1673 women aged 49-63 years from the Copenhagen Ageing and Midlife Biobank (CAMB) with complete information on measured BMI, severity of mental symptoms assessed by the Symptom Check-List' (SCL-90), and socio-demographic factors including sex, age, occupational social class, and educational duration. Linear and logistic regression were used to evaluate associations between BMI category and SCL-90. RESULTS Unadjusted SCL-90 subscale scores differed significantly across BMI categories (p < 0.001) among both men and women with more mental distress in the underweight, obese and severely obese BMI categories except for the anxiety scale which was not associated with BMI category in women. In the adjusted analyses, all symptom scales remained significantly associated with BMI among men after adjusting for socio-demographic factors while only associations with somatization and depression scales remained significant for women.. When SCL-90 case status was applied as an outcome, significant unadjusted associations with BMI category were observed for somatization (p < 0.001), depression (p = 0.026) and the General Severity Index (p = 0.002) among men and somatization (p = 0.002) among women. Furthermore, somatization case-status was significantly predicted by BMI category (p < 0.001) in men after adjusting for socio-demographic factors. CONCLUSION Results indicate more mental distress among underweight, obese and severely obese men and women after adjusting for socio-demographic factors. Furthermore, obese men have higher risk of reporting clinically relevant symptoms of somatization independently of socio-demographic factors.

Abstract
PURPOSE General self-efficacy has been historically assumed to have universal health implications. However, less is known about population differences in long-term health effects of general self-efficacy across diverse populations. This study compared black and white American adults for (1) the association between psychosocial and health factors and general self-efficacy at baseline, and (2) the association between baseline self-efficacy and long-term risk of all-cause mortality over 25 years. METHODS The Americans' Changing Lives (ACL) study, 1986-2011, is a nationally representative longitudinal cohort of US adults. The study followed 3361 black (n = 1156) and white (n = 2205) adults for up to 25 years. General self-efficacy as well as demographics, socioeconomics, stressful life events, health behaviors, obesity, depressive symptoms, and self-rated health were measured at baseline in 1986. The outcome was time to all-cause mortality since 1986. Race was the focal moderator. Logistic regression and proportional hazards models were used for data analysis. RESULTS Although blacks had lower general self-efficacy, this association was fully explained by socioeconomic factors (education and income). Our logistic regression suggested interactions between race and education, self-rated health, and stress on general self-efficacy at baseline. Baseline general self-efficacy was associated with risk of mortality in the pooled sample. Race interacted with baseline general self-efficacy on mortality risk, suggesting stronger association for whites than blacks. CONCLUSION Black-white differences exist in psychosocial and health factors associated with self-efficacy in the USA. Low general self-efficacy does not increase mortality risk for blacks. Future research should test whether socioeconomic status, race-related attitudes, world views, attributions, and locus of control can potentially explain why low self-efficacy is not associated with higher risk of mortality among American blacks.
