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

Psychosocial factors associated with 7-year change in cognition among middle-aged and older Hispanics/Latinos: The Hispanic Community Health Study/Study of Latinos-Investigation of Neurocognitive Aging (SOL-INCA) and Sociocultural ancillary studies

INTRODUCTION

Few studies have examined the associations of psychosocial factors with cognitive change in Hispanics/Latinos.

METHODS

Data from the Hispanic Community Health Study/Study of Latinos-Investigation of Neurocognitive Aging (HCHS/SOL INCA) and Sociocultural studies were used (n = 2,155; ages ≥45 years). Psychosocial exposures included intrapersonal (ethnic identity, optimism, purpose in life), interpersonal (family cohesion, familism, social networks, social support), and social factors (ethnic discrimination, loneliness, subjective social status). Survey-linear regression models examined associations between psychosocial exposures and 7-year cognitive change (global cognition [GC], verbal learning, memory, word fluency [WF], and digit symbol substitution [DSS]).

RESULTS

Familism predicted decline in GC, verbal learning, and memory; family cohesion predicted DSS decline; and loneliness predicted memory decline. Ethnic identity was protective against decline in GC and memory, optimism and social support were protective against decline in memory, and purpose in life was protective against WF decline.

DISCUSSION

Psychosocial factors are differentially related to cognitive changes. Culturally relevant factors should be explored in Hispanic/Latino cognitive aging research.

HIGHLIGHTS

Psychosocial factors are differentially related to cognitive changes in Latinos. Role of culturally relevant factors on cognition should be further explored. Familism predicted decline in global cognition, verbal learning, and memory. Ethnic identity predicted increase in global cognition and memory.

Mental Health of Brazilian Immigrant Women: The Role of Discrimination, Social Support, and Community Strengths

Little is known about the mental health status of Brazilians living in the U.S. We assessed the prevalence and correlates of depression to guide the development of culturally relevant community-based mental health interventions. An online survey was conducted between July and August 2020 among a sample of Brazilian women living in the U.S. (age 18 and over, born in Brazil, English or Portuguese speaking) recruited through Brazilian social media pages and community organizations. The survey assessed depression using the Center for Epidemiological Study Depression Scale (CES-D-10), the Everyday Discrimination Scale (EDS), the Oslo Social Support Scale (OSSS), and community strengths (CS). We first assessed the correlation between CES-D-10 scores and EDS, OSSS, and CS. We found that half of the participants (52.2%) had CES-D-10 scores of 10 or greater, indicating the presence of depressive symptomatology. In a multivariable model controlling for significant covariates (age, time lived in U.S.), EDS was positively associated with CES-D-10 scores (β = 0.64, 95% CI = 0.45, 0.83), while OSSS was negatively associated with CES-D-10 scores (β = -0.53, 95% C I= -0.80, -0.27). No statistically significant relationship was observed between CES-D-10 and CS scores. In this sample of Brazilian immigrant women, depressive symptomatology was highly prevalent, and experiences of discrimination were associated with increased symptoms of depression. There is a need to understand and address mental health in Brazilian immigrant women.

Electronic Monitoring of Mom's Schedule (eMOMSTM): A Qualitative Study of Experiences in a Lifestyle Change Program with Lactation Support

PURPOSE

To elicit feedback from participants who completed the eMOMSTM study, a feasibility randomized controlled trial (NCT04021602), on their perceptions of program strengths and weaknesses.

STUDY DESIGN

Qualitative - Semi-structured, telephone interview guide using open-ended questions.

SETTING

Rural Great Plains state, United States.

PARTICIPANTS

Of 26 individuals who completed the eMOMSTM study, 24 consented to an interview.

METHOD

Interviews were completed between October 2020 and May 2021. Audio-recordings were transcribed verbatim and organized in Microsoft 365. Data were analyzed using an exploratory, inductive thematic analysis.

RESULTS

Participants' mean age was 27.5 (± 5.4) years and mean pre-pregnancy BMI was 29.5 kg/m2 (± 2.7). The majority (71%) were non-Hispanic White and 54% had a high school education/some college. Based on specific areas of inquiry, the following themes emerged: convenience of online program access using Facebook, importance of health coach's support and online interaction, positivity toward improving one's health, increased consciousness of health behaviors, diverse lactation educational needs, importance of educational materials on depression, and grief over the loss of birth expectations during COVID-19.

CONCLUSION

Findings suggest participants' perceived value of a lifestyle change program coupled with lactation education and support delivered using social media. Findings inform future studies to further adapt lifestyle change programs.

Discrimination and Sleep: Differential Effects by Type and Coping Strategy

BACKGROUND

Discrimination has been posited as a contributor of sleep disparities for Latinxs. The strategy used to cope with discrimination may reduce or exacerbate its effects on sleep. This study examined whether different types of discrimination (everyday and major lifetime discrimination) were associated with sleep indices (quality, disturbances, efficiency) and whether coping strategy used moderated associations.

METHOD

Data of Latinx adults (N = 602; 51% women, 65% Dominican, Mage = 46.72 years) come from the Latino Health and Well-being Project, a community-based, cross-sectional study of Latinxs in Lawrence, MA. Multiple linear regressions were estimated separately for each sleep outcome.

RESULTS

Everyday discrimination was significantly associated with poorer sleep quality and greater disturbances; major lifetime discrimination was significantly associated with worse sleep across the three sleep indices. Coping strategy moderated associations between discrimination and sleep. Compared with Latinxs who used passive coping, those who used passive-active coping strategies had poorer sleep quality the more they experienced everyday discrimination. Latinxs who used any active coping strategy, compared with passive coping, had greater sleep disturbances the more frequently they experienced major lifetime discrimination.

CONCLUSIONS

Findings show that everyday discrimination and major lifetime discrimination are associated with different dimensions of sleep and suggest that coping with discrimination may require the use of different strategies depending on the type of discrimination experienced.

Assessing Hispanic/Latino and Non-Hispanic White Social Determinants of Obesity Among a Community Sample of Residents in the Rural Southeast US

Employing an ecological approach, we sought to identify social determinants of obesity among Hispanics/Latinos and non-Hispanic whites living in the Southeast US. Data on social determinants of obesity (individual, family, community and cultural/contextual) were collected from 217 participants [106 Hispanics/Latinos; 111 non-Hispanic whites]; height and weight  were objectively measured. We compared prevalence of overweight and obese between ethnic groups and BMI values within each group by social determinants. Hispanics had a 1.9-fold increase (OR 1.93, 95% CI: 1.05-3.55) in overweight prevalence compared to non-Hispanic whites after adjusting for age and gender. We found positive estimates between unfavorable family-level determinants and BMI among Hispanic/Latinos. In contrast, non-Hispanic whites who reported unfavorable neighborhood characteristics had higher BMI's. Findings highlight the need for targeted approaches for the prevention and control of obesity.

Skin Tone, Race/Ethnicity, and Gender Differences in BMI among New US Immigrants

Scholars have been interested in the relationship between skin tone and health since at least the 1970s; however, no study, to our knowledge, has analyzed a diverse immigrant sample. In this study, we use the New Immigrant Survey and interactions to examine how skin tone and race/ethnicity - alongside gender - jointly pattern BMI among Legal Permanent Residents. Our approach allows for the analysis of BMI among multiple racial/ethnic immigrant groups, while considering skin tone. Our results document that darker skin shades are associated with higher BMI, but only for women. Further, we also tease out the relationship between gender and race/ethnicity for BMI, which allows us to better understand this critical connection for new immigrants' health in the United States. Together, our results highlight that BMI jointly varies by skin tone and race/ethnicity, which emphasizes the importance of an intersectional approach, especially for new immigrant women of color.

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.

Psychosocial stressors predict lower cardiovascular disease risk among Mexican-American adults living in a high-risk community: Findings from the Texas City Stress and Health Study

The objective of this study was to examine the link between systemic and general psychosocial stress and cardiovascular disease (CVD) risk in a group of U.S. Latinos as a function of acculturation and education within the blended guiding conceptual framework of the biopsychosocial model of the stress process plus the reserve capacity model. We analyzed data from self-identifying Mexican-origin adults (n = 396, 56.9% female, Mage = 58.2 years, 55.5% < 12 years of education, 79% U.S.-born) from the Texas City Stress and Health Study. We used established measures of perceived stress (general stress), neighborhood stress and discrimination (systemic stress) to capture psychosocial stress, our primary predictor. We used the atherosclerotic CVD calculator to assess 10-year CVD risk, our primary outcome. This calculator uses demographics, cholesterol, blood pressure, and history of hypertension, smoking, and diabetes to compute CVD risk in the next 10 years. We also created an acculturation index using English-language use, childhood interaction, and preservation of cultural values. Participants reported years of education. Contrary to expectations, findings showed that higher levels of all three forms of psychosocial stress, perceived stress, neighborhood stress, and perceived discrimination, predicted lower 10-year CVD risk. Acculturation and education did not moderate the effects of psychosocial stress on 10-year CVD risk. Contextualized within the biopsychosocial and reserve capacity framework, we interpret our findings such that participants who accurately reported their stressors may have turned to their social networks to handle the stress, thereby reducing their risk for CVD. We highlight the importance of examining strengths within the sociocultural environment when considering cardiovascular inequities among Latinos.

Racial Discrimination and Depressive Symptoms among Latina/o College Students: The Role of Racism-Related Vigilance and Sleep

INTRODUCTION

Latinx college students are at high risk of suffering from depressive symptoms. A factor posited to influence depressive symptoms among Latinx college students is racial/ethnic discrimination. However, the mechanisms which link racial/ethnic discrimination to depressive symptoms are not well understood. This study examined the mediating role of racism-related vigilance and sleep-related factors (i.e., sleep quality, sleep efficiency) on the relationship between perceived intergroup racial/ethnic discrimination and depressive symptoms.

METHODS

Participants were 194 Latinx college students enrolled at a Midwestern university designated as a Hispanic-Serving Institution. Path analysis was conducted to investigate whether racism-related vigilance and sleep-related factors (i.e. sleep quality, sleep efficiency) are potential pathways in the relationship between intergroup racial/ethnic discrimination and depressive symptoms.

RESULTS

Path analysis revealed that racism-related vigilance and sleep quality sequentially mediated the effect of perceived intergroup racial/ethnic discrimination on depressive symptoms. Sleep efficiency did not mediate the relationship between racial/ethnic discrimination and depressive symptoms.

DISCUSSION

This study is among the first to document that intergroup racial/ethnic discrimination is negatively related to mental health through both cognitive and behavioral mechanisms. This research has important implications for understanding how discrimination may influence mental health outcomes among Latinx college students.

Everyday discrimination among formerly homeless persons in permanent supportive housing

Experiences of discrimination are associated with poor health and are particularly common among persons experiencing homelessness. Permanent supportive housing (PSH) provides a foundation for improved well-being among persons with homelessness histories, but research on discrimination among this population is lacking. We examined changes in experiences of, and perceived reasons for, everyday discrimination when persons moved into PSH. 421 adults in Los Angeles County completed baseline (pre-housing), 3-, 6- or 12-month post-housing structured interviews. Generalized linear mixed models (GLMM) examined change in discrimination outcomes, controlling for demographic characteristics. Everyday discrimination experiences decreased significantly when persons moved from homelessness into PSH, and remained consistently lower across the first year in PSH. Reports of homelessness/poverty, race/ethnicity, and neighborhood as reasons for discrimination also decreased from baseline levels. PSH may offer respite from everyday discrimination, but the persistence of discrimination and particularly racism in society requires structural solutions addressing implicit bias and systemic inequities.
