Racial/Ethnic Differences in Cardiometabolic Risk in a Community Sample of Sexual Minority Women

The Extent, Range, and Nature of Quantitative Nutrition Research Engaging with Intersectional Inequalities: A Systematic Scoping Review

Addressing malnutrition for all requires understanding inequalities in nutrition outcomes and how they intersect. Intersectionality is increasingly used as a theoretical tool for understanding how social characteristics intersect to shape inequalities in health outcomes. However, little is known about the extent, range, and nature of quantitative nutrition research engaging with intersectional inequalities. This systematic scoping review aimed to address this gap. Between 15 May 2021 and 15 May 2022, we searched 8 databases. Studies eligible for inclusion used any quantitative research methodology and aimed to investigate how social characteristics intersect to influence nutrition outcomes. In total, 55 studies were included, with 85% published since 2015. Studies spanned populations in 14 countries but were concentrated in the United States (n = 35) and India (n = 7), with just 1 in a low-income country (Mozambique). Race or ethnicity and gender were most commonly intersected (n = 20), and body mass index and overweight and/or obesity were the most common outcomes. No studies investigated indicators of infant and young child feeding or micronutrient status. Study designs were mostly cross-sectional (80%); no mixed-method or interventional research was identified. Regression with interaction terms was the most prevalent method (n = 26); 2 of 15 studies using nonlinear models took extra steps to assess interaction on the additive scale, as recommended for understanding intersectionality and assessing public health impacts. Nine studies investigated mechanisms that may explain why intersectional inequalities in nutrition outcomes exist, but intervention-relevant interpretations were mostly limited. We conclude that quantitative nutrition research engaging with intersectionality is gaining traction but is mostly limited to the United States and India. Future research must consider the intersectionality of a wider spectrum of public health nutrition challenges across diverse settings and use more robust and mixed-method research to identify specific interventions for addressing intersectional inequalities in nutrition outcomes. Data systems in nutrition must improve to facilitate this. This review was registered in PROSPERO as CRD42021253339.

Intersectionality in nursing research: A scoping review

Background

An intersectional approach to health research provides an analytical foundation to explain the multidimensionality of health status, resource accessibility, privilege, oppression, and current and historical context. The use of intersectionality in health research has known limitations. Its use in health-related fields too often focuses on outcomes, such as health disparities, rather than processes, such as power structures and social determinants.

Objective

This scoping review serves to examine how intersectionality has been implemented by nurses in the peer-reviewed literature. We offer insight into how it may be incorporated to inform future nursing research and healthcare provision.

Design & Methods

Systematic searches of PubMed (n = 257), SCOPUS (n = 807), EMBASE (n = 396), CINAHL (n = 224), and Health Source: Nursing and Academics (n = 491), published since the seminal publication on intersectionality (1989 - 2023), identified 131 research articles that met inclusion and exclusion criteria. Data extraction and synthesis were used to describe the breadth and depth of the literature specific to the application of intersectionality in nursing research.

Results

The included studies used intersectionality to examine the intersections of numerous identities, such as race, gender, and immigration status. However, most studies were descriptive/observational in nature, underreported their methods, and conducted deficit-based research instead of strength-based inquiries. Of note, the vast majority of included articles were published within the last five years.

Conclusions

Future researchers using intersectionality as a framework can improve their approach by reporting clear definitions and operationalization of intersectionality. Observational science dominated the included studies; future research should focus on intervention development and evaluation using an intersectional lens. Lastly, caution should be placed on research that focuses solely on deficits among marginalized communities, which places scientists at risk of perpetuating stereotypes or enhancing already-existing stigmas.

Investigating the Associations of Sexual Minority Stressors and Incident Hypertension in a Community Sample of Sexual Minority Adults

BACKGROUND

Sexual minority adults are at higher risk of hypertension than their heterosexual counterparts. Sexual minority stressors (i.e., unique stressors attributed to sexual minority identity) are associated with a variety of poor mental and physical health outcomes. Previous research has not tested associations between sexual minority stressors and incident hypertension among sexual minority adults.

PURPOSE

To examine the associations between sexual minority stressors and incident hypertension among sexual minority adults assigned female sex at birth.

METHODS

Using data from a longitudinal study, we examined associations between three sexual minority stressors and self-reported hypertension. We ran multiple logistic regression models to estimate the associations between sexual minority stressors and hypertension. We conducted exploratory analyses to determine whether these associations differed by race/ethnicity and sexual identity (e.g., lesbian/gay vs. bisexual).

RESULTS

The sample included 380 adults, mean age 38.4 (± 12.81) years. Approximately 54.5% were people of color and 93.9% were female-identified. Mean follow-up was 7.0 (± 0.6) years; during which 12.4% were diagnosed with hypertension. We found that a 1-standard deviation increase in internalized homophobia was associated with higher odds of developing hypertension (AOR 1.48, 95% Cl: 1.06-2.07). Stigma consciousness (AOR 0.85, 95% CI: 0.56-1.26) and experiences of discrimination (AOR 1.07, 95% CI: 0.72-1.52) were not associated with hypertension. The associations of sexual minority stressors with hypertension did not differ by race/ethnicity or sexual identity.

CONCLUSIONS

This is the first study to examine the associations between sexual minority stressors and incident hypertension in sexual minority adults. Implications for future studies are highlighted.

Modulation of cardiometabolic risk and CardioRenal syndrome by oral vitamin D3 supplementation in Black and White Southern Sahara residents with chronic kidney disease Stage 3: focus on racial and ethnic disparities

OBJECTIVES

Several studies have shown that cholecalciferol supplementation (25OHD-S) in chronic kidney disease (CKD) improves kidney injury by reducing fibrosis-related vascular calcification and declining apoptosis-linked nephron damage.

METHODS

The oral 25OHD-S was evaluated in 60,000 IU/month/36 weeks versus in 2000 IU/d/24 weeks in CKD Stage 3 with serum 25OHD level < 20 ng/mL. The study was undertaken on 156 black subjects and 150 white subjects Southern Sahara (SS). All biomarkers of cardiometabolic (CMet) and cardiorenal (CRenal) syndrome, Renin-angiotensin-aldosterone system (RAAS) profile, secondary hyperparathyroidism (SHPT), N-terminal pro B-type natriuretic peptide (NT-proBNP), Troponin T (cTnT) and atherogenicity risk were assessed by biochemical methods. Estimate glomerular filtration rate (eGFR) by chronic CKD-EPI equation formula. Total serum vitamin D by liquid chromatography-tandem mass spectrometry (MS).

RESULTS

Vitamin D deficiency alters in the same manner CMet, CRenal, and others biomarkers in both groups SS; however, these disorders are more acute in blacks compared to whites SS. Oral 25OHD-S a highlighted improvement of eGFR drop, SHPT decrease, decline proteinuria, and cardiac failure risk (NT-proBNP and cTnT) attenuation. Concomitantly, 25OHD-S normalizes Renin, Aldosterone, and Angiotensin System (RAAS) activity. Nevertheless, homocysteine and Lp (a) do not modulate by 25OHD-S.

CONCLUSIONS

The oral vitamin D3 supplementation, according the dose, and the treatment duration does not like in black-skinned people versus to white-skinned inhabitants, while the 02 groups are native to the same Saharan environment. It emerge that a high intermittent dose through an extensive supplementation (60,000 IU/36 weeks) was more effective in black subjects. At opposite, a lower dose during a short period supplementation is sufficient (2000 IU/24 weeks) in white subjects.

A Systematic Review of Black American Same-Sex Couples Research: Laying the Groundwork for Culturally-Specific Research and Interventions

ABSTRACTThis article presents the findings of a systematic review of the empirical literature related to Black American same-sex couples (BASCs). We found 16 articles that met inclusion criteria. Most articles were published in journals that focused on interdisciplinary studies, HIV/AIDS, and couples and families' studies. Approximately 63% of the articles reported external funding support. However, only one of these grants was awarded to a Black investigator. Articles predominately focused on BASCs composed of Black sexual minority men residing in major U.S. cities. Only 25% of the articles focused on couples where both partners were Black. Most studies were cross-sectional, used convenience samples, and were reported without mention of a theoretical framework that explicated the philosophical assumptions that guided the research. The articles focused on a range of topics such as resilience, relationship dynamics, couple-level social support, rituals with extended families, and partner-health associations. The implications of these findings for advancing culturally-specific behavioral and social science health research and interventions with BASCs are presented.

A population-based study of the intersection of sexual identity and race/ethnicity on physiological risk factors for CVD among U.S. adults (ages 18-59)

Objectives: Sexual minorities face significant psychosocial stressors (such as discrimination and violence) that impact their health. Several studies indicate that sexual minority women (SMW) and bisexual men may be at highest risk for cardiovascular disease (CVD), but limited research has examined physiological CVD risk or racial/ethnic differences. This study sought to examine racial/ethnic differences in physiological risk factors for CVD among sexual minority and heterosexual adults.Design: We analyzed data from the National Health and Nutrition Examination Survey (2001-2016) using sex-stratified multiple linear regression models to estimate differences in physiological CVD risk. We compared sexual minorities (gay/lesbian, bisexual, 'not sure') to heterosexual participants first without regard to race/ethnicity. Then we compared sexual minorities by race/ethnicity to White heterosexual participants.Results: The sample included 22,305 participants (ages 18-59). Lesbian women had higher body mass index (BMI) but lower total cholesterol than heterosexual women. Bisexual women had higher systolic blood pressure (SBP). Gay men had lower BMI and glycosylated hemoglobin (HbA1c) relative to heterosexual men. White and Black lesbian women and bisexual women of all races/ethnicities had higher BMI than White heterosexual women; Black bisexual women had higher SBP and HbA1c. Black sexual minority men had higher HbA1c relative to White heterosexual men. Latino 'not sure' men also had higher SBP, HbA1c, and total cholesterol than White heterosexual men.Conclusions: Given evidence of higher CVD risk in sexual minority people of color relative to White heterosexuals, there is a need for health promotion initiatives to address these disparities. Additional research that incorporates longitudinal designs and examines the influence of psychosocial stressors on CVD risk in sexual minorities is recommended. Findings have implications for clinical and policy efforts to promote the cardiovascular health of sexual minorities.

Moving the Paradigm Forward for Prediction and Risk-Based Primary Prevention of Heart Failure in Special Populations

PURPOSE OF REVIEW

Heart failure (HF) treatment paradigms increasingly recognize the importance of primary prevention. This review explores factors that enhance HF risk, summarizes evidence supporting the pharmacologic primary prevention of HF, and notes barriers to the implementation of primary prevention of HF with a focus on female and sexual and gender minority patients.

RECENT FINDINGS

HF has pathophysiologic sex-specific distinctions, suggesting that sex-specific preventive strategies may be beneficial. Pharmacologic agents that have shown benefit in reducing the risk of HF address the pathobiology underpinning these sex-specific risk factors. The implementation of pharmacologic therapies for primary prevention of HF needs to consider a risk-based model. Current pharmacotherapies hold mechanistic promise for the primary prevention of HF in females and gender and sexual minorities, although research is needed to understand the specific populations most likely to benefit. There are significant systemic barriers to the equitable provision of HF primary prevention.

Diet, Food Insecurity, and CVD Risk in Sexual and Gender Minority Adults

Purpose of Review

Sexual and gender minority (SGM) adults experience significant cardiovascular health disparities, yet little is known about diet and food insecurity in this population. This review summarizes recent literature on diet and food insecurity in SGM adults and their contribution to cardiovascular disease (CVD) risk in this population.

Recent Findings

Existing evidence on diet and food insecurity disparities among SGM adults is inconclusive and research examining their link with CVD risk in SGM adults is limited. The majority of existing studies lack standardized and validated assessments of diet and food insecurity. Correlates of unhealthy diet and food insecurity among SGM adults are poorly understood.

Summary

Research examining the associations between diet and food insecurity with CVD risk in SGM adults is limited. Longitudinal studies are needed to investigate whether diet and food insecurity contribute to the cardiovascular health disparities observed in SGM adults.

The Association between Hazardous Drinking Indicators and Drinking Problem Concerns among Sexual Minority Women

Sexual minority women (SMW) report high rates of hazardous drinking (HD), treatment utilization that is not commensurate with need, and low perceived alcohol use severity. This study examined SMW's drinking problem concerns by sexual identity and other demographic characteristics, and the strength of associations between endorsement of unique HD indicators and drinking problem concerns. Data were from a supplemental sample of SMW added in Wave 3 of the longitudinal, community-based Chicago Health and Life Experiences of Women (CHLEW) study. HD was measured using a validated 13-item HD Index (HDI). Multivariable logistic regression models examined independent associations between past-five-year drinking problem concerns and each HD indicator. Twelve HD indicators were significantly associated with past-five-year drinking problem concerns, adjusting for age and sexual identity. Adjusted odds ratios varied from 2.44 for driving drunk to 15.52 for drinking first thing in the morning. After adjusting for number of HD indicators endorsed, associations were no longer significant, indicating that number of endorsed indicators was a more important predictor of drinking problem concerns than were individual HD indicators. Early intervention and harm reduction strategies could support SMW in addressing salient aspects of HD before progression to alcohol use disorder.

Sexual and Gender Minority Health Care Disparities: Barriers to Care and Strategies to Bridge the Gap

Gender and sexual minority individuals face considerable physical and mental health disparities, health risk factors, and barriers to care. These disparities are rooted in systemic and interpersonal prejudice, discrimination, and violence toward lesbian, gay, bisexual, transgender, queer, and other (LGBTQ+) individuals and communities that place LGBTQ+ individuals at increased risk for negative social determinants of health. While also advocating for systemic change, individual providers and clinics have an ethical duty to promote an openly affirming, culturally competent health care environment that can help to address these disparities on an individual patient level.

Past-year discrimination and cigarette smoking among sexual minority women: investigating racial/ethnic and sexual identity differences

Although findings are mixed, discrimination has been identified as a risk factor for smoking in sexual minority women (SMW; e.g., lesbian and bisexual). We examined associations between past-year discrimination and cigarette smoking among SMW. Using regression analyses we examined associations of past-year discrimination including count of types of discriminatory experiences and attributions of the main reason for discrimination (i.e., sexual orientation, race/ethnicity, gender) with smoking outcomes (e.g., current smoking, nicotine dependence, smoking more cigarettes now than 12 months ago). We conducted exploratory analyses to examine whether race/ethnicity and sexual identity moderated the associations of past-year discrimination with smoking outcomes. The sample included 619 SMW. Most identified as lesbian (74.3%) and non-White (61.1%). SMW who reported a higher count of types of discriminatory experiences (AOR 1.54, 95% CI 1.12-2.12) and any gender-based discrimination in the past year (AOR 4.79, 95% CI 1.39-16.45) reported smoking more cigarettes now than 12 months ago. Associations of other past-year discrimination measures with other smoking outcomes were not significant. Compared to White SMW, any discrimination [B (SD) = 2.56 (0.83)] and a higher count of types of discriminatory experiences in the past year [B (SD) = 0.88 (0.31)] were associated with higher nicotine dependence scores in Black/African American SMW. Past-year discrimination are associated with smoking outcomes in SMW. Black/African American race moderated the associations of any past-year discrimination and a higher count of types of discriminatory experiences with nicotine dependence scores in SMW. Targeted interventions to mitigate the influence of discrimination on smoking among SMW are needed.

Disparities in food insecurity at the intersection of race and sexual orientation: A population-based study of adult women in the United States

Food insecurity affects 1 in 8 American adults annually, and is more prevalent in Black and sexual minority women. We applied an intersectional approach to investigate food insecurity prevalence in women with intersecting minority race and sexual orientation. We used two United States surveillance systems-National Health Interview Survey (NHIS) 2013-2018 and National Health and Nutrition Examination Survey (NHANES) 2005-2014, to estimate how race and sexual orientation jointly influence food insecurity prevalence in women aged 18-59 years (NHIS: N = 47596; NHANES: N = 5106). All analyses were stratified for Supplemental Nutrition Assistance Program (SNAP) use. Relative measures estimated weighted prevalence ratios (PR) comparing Black and White sexual minority women (SMW) to heterosexual White women. Absolute prevalence measures estimated the excess prevalence of food insecurity due to multiple marginalization. Patterns of food insecurity prevalence were similar across NHIS and NHANES, and differed only for non-SNAP users. Relative prevalence of food insecurity was greater in Black SMW than heterosexual White women in NHIS (PR: 2.16; 95% confidence interval [CI], 1.41-3.30) and NHANES (PR: 2.79; 95% CI, 1.73-4.51). The strength of the association between multiple marginalization and food insecurity was stronger for Black SMW than White SMW. Absolute measures were significant only for NHIS and did not support our a priori hypothesis: For non-SNAP users, being Black and sexual minority reduced the joint disparity in food insecurity by approximately 50% (Synergy Index: 0.52; 95% CI, 0.11-0.93). Overall, our study illuminated population-level differences in food insecurity among women of diverse minority races and sexual orientations. Black SMW experienced high rates of food insecurity, which may contribute to chronic disease disparities. Yet, intersecting minority social positions (race and sexual orientation) reduced food insecurity; these findings are unexpected and must be further investigated. Increasing SNAP use among multiply marginalized women may attenuate food insecurity disparities.

Assessing and Addressing Cardiovascular Health in LGBTQ Adults: A Scientific Statement From the American Heart Association

There is mounting evidence that lesbian, gay, bisexual, transgender, and queer or questioning (LGBTQ) adults experience disparities across several cardiovascular risk factors compared with their cisgender heterosexual peers. These disparities are posited to be driven primarily by exposure to psychosocial stressors across the life span. This American Heart Association scientific statement reviews the extant literature on the cardiovascular health of LGBTQ adults. Informed by the minority stress and social ecological models, the objectives of this statement were (1) to present a conceptual model to elucidate potential mechanisms underlying cardiovascular health disparities in LGBTQ adults, (2) to identify research gaps, and (3) to provide suggestions for improving cardiovascular research and care of LGBTQ people. Despite the identified methodological limitations, there is evidence that LGBTQ adults (particularly lesbian, bisexual, and transgender women) experience disparities across several cardiovascular health metrics. These disparities vary by race, sex, sexual orientation, and gender identity. Future research in this area should incorporate longitudinal designs, elucidate physiological mechanisms, assess social and clinical determinants of cardiovascular health, and identify potential targets for behavioral interventions. There is a need to develop and test interventions that address multilevel stressors that affect the cardiovascular health of LGBTQ adults. Content on LGBTQ health should be integrated into health professions curricula and continuing education for practicing clinicians. Advancing the cardiovascular health of LGBTQ adults requires a multifaceted approach that includes stakeholders from multiple sectors to integrate best practices into health promotion and cardiovascular care of this population.

Sexual Identity and Racial/Ethnic Differences in Awareness of Heart Attack and Stroke Symptoms: Findings From the National Health Interview Survey

PURPOSE

Investigate sexual identity and racial/ethnic differences in awareness of heart attack and stroke symptoms.

DESIGN

Cross-sectional.

SETTING

2014 and 2017 National Health Interview Survey.

SAMPLE

54 326 participants.

MEASURES

Exposure measures were sexual identity (heterosexual, gay/lesbian, bisexual, "something else") and race/ethnicity. Awareness of heart attack and stroke symptoms was assessed.

ANALYSIS

Sex-stratified logistic regression analyses to examine sexual identity and racial/ethnic differences in awareness of heart attack and stroke symptoms.

RESULTS

Gay men were more likely than heterosexual men to identify calling 911 as the correct action if someone is having a heart attack (adjusted odds ratio [AOR] = 2.16, 95% CI: 1.18-3.96). The majority of racial/ethnic minority heterosexuals reported lower rates of awareness of heart attack and stroke symptoms than White heterosexuals. Hispanic sexual minority women had lower awareness of heart attack symptoms than White heterosexual women (AOR = 0.43, 95% CI: 0.25-0.74), whereas Asian sexual minority women reported lower awareness of stroke symptoms (AOR = 0.25, 95% CI: 0.08-0.80). Hispanic (AOR = 0.52, 95% CI: 0.33-0.84) and Asian (AOR = 0.35, 95% CI: 0.14-0.84) sexual minority men reported lower awareness of stroke symptoms than White heterosexual men.

CONCLUSION

Hispanic and Asian sexual minorities had lower rates of awareness of heart attack and stroke symptoms. Health information technology may be a platform for delivering health education and targeted health promotion for sexual minorities of color.
