Racial Disparities in Hypertension Prevalence within US Gentrifying Neighborhoods

Race Disparities in Hypertension Prevalence Among Older Men

This study aimed to examine whether hypertension prevalence varies by race/ethnicity and within age groups in a nationally representative sample of men in the United States. Hypertension was defined as blood pressure (BP) readings of 140 mm Hg and higher for systolic BP, 90 mm Hg and higher for diastolic BP, or self-reports of taking medication for hypertension. Modified Poisson models estimated prevalence ratios (PRs) and 95% confidence intervals (CI) for race and age group associations with hypertension. The prevalence of hypertension was 38% overall and 46% of the men were aged 50 and older. Analyses that focused on older men (50 years of age or older) found that non-Hispanic Black men had a higher prevalence of hypertension (PR  =  1.28, 95% CI: 1.19 - 1.37) compared to non-Hispanic White men. We suggest future research utilize life course perspectives to better identify which cumulative experiences impact hypertension disparities.

Barriers and facilitators to self-measured blood pressure monitoring among US-resettled Arab refugees with hypertension: a qualitative study

BACKGROUND

Minoritized communities including refugees are at an increased risk of poorly controlled hypertension. Evidence indicates that self-measured blood pressure monitoring (SMBP) is an effective method to improve blood pressure control in patients with hypertension. However, it has not been studied among refugee populations. The objective of this study is to examine barriers and facilitators to SMBP among Arab refugees resettled in the United States (US) with diagnosed hypertension.

METHODS

A total of 109 participants were recruited through a Federally Qualified Health Center system that is a major provider of healthcare to refugees in San Diego, California. Participants completed a questionnaire and were interviewed using in-depth, semi-structured interviews. Interviews were transcribed and translated, and data were coded using inductive thematic analysis and organized based on the theory of care-seeking behavior.

RESULTS

Several barriers to engaging in effective SMBP monitoring were identified. Clinical and sociodemographic barriers included reliance on public monitors and poor hypertension literacy. Psychosocial barriers of affect, norms, and habits included fear and anxiety from hypertension, cultural stigma of illness, and conditional SMBP with symptoms, respectively. Utility psychosocial barriers included lack of SMBP prioritization in treatment and perceived inaccuracy of home monitors. Family members' support with home monitoring served as an important facilitator to SMBP.

CONCLUSIONS

There are several barriers to effective SMBP among the US-resettled Arab refugee population that may reflect unique cultural and care-seeking behaviors. Tailored public health and clinical interventions are needed to support refugee patients and providers to improve hypertension self-management behaviors for this unique population.

Neighborhood Characteristics and Elevated Blood Pressure in Older Adults

Importance

The local environment remains an understudied contributor to elevated blood pressure among older adults. Untargeted approaches can identify neighborhood conditions interrelated with racial segregation that drive hypertension disparities.

Objective

To evaluate independent associations of sociodemographic, economic, and housing neighborhood factors with elevated blood pressure.

Design, Setting, and Participants

In this cohort study, the sample included Health and Retirement Study participants who had between 1 and 3 sets of biennial sphygmomanometer readings from 2006 to 2014 or 2008 to 2016. Statistical analyses were conducted from February 5 to November 30, 2021.

Exposures

Fifty-one standardized American Community Survey census tract variables (2005-2009).

Main Outcomes and Measures

Elevated sphygmomanometer readings over the study period (6-year period prevalence): a value of at least 140 mm Hg for systolic blood pressure and/or at least 90 mm Hg for diastolic blood pressure. Participants were divided 50:50 into training and test data sets. Generalized estimating equations were used to summarize multivariable associations between each neighborhood variable and the period prevalence of elevated blood pressure, adjusting for individual-level covariates. Any neighborhood factor associated (Simes-adjusted for multiple comparisons P ≤ .05) with elevated blood pressure in the training data set was rerun in the test data set to gauge model performance. Lastly, in the full cohort, race- and ethnicity-stratified associations were evaluated for each identified neighborhood factor on the likelihood of elevated blood pressure.

Results

Of 12 946 participants, 4565 (35%) had elevated sphygmomanometer readings (median [IQR] age, 68 [63-73] years; 2283 [50%] male; 228 [5%] Hispanic or Latino, 502 [11%] non-Hispanic Black, and 3761 [82%] non-Hispanic White). Between 2006 and 2016, a lower likelihood of elevated blood pressure was observed (relative risk for highest vs lowest tertile, 0.91; 95% CI, 0.86-0.96) among participants residing in a neighborhood with recent (post-1999) in-migration of homeowners. This association was precise among participants with non-Hispanic White and other race and ethnicity (relative risk, 0.91; 95% CI, 0.85-0.97) but not non-Hispanic Black participants (relative risk, 0.97; 95% CI, 0.85-1.11; P = .48 for interaction) or Hispanic or Latino participants (relative risk, 0.84; 95% CI, 0.65-1.09; P = .78 for interaction).

Conclusions and Relevance

In this cohort study of older adults, recent relocation of homeowners to a neighborhood was robustly associated with reduced likelihood of elevated blood pressure among White participants but not their racially and ethnically marginalized counterparts. Our findings indicate that gentrification may influence later-life blood pressure control.

Association of neighborhood gentrification and residential moves with hypertension and diabetes control in Los Angeles County, 2014-2019: A retrospective cohort study

OBJECTIVE

To examine whether gentrification exposure is associated with future hypertension and diabetes control.

METHODS

Linking records from an integrated health care system to census-tract characteristics, we identified adults with hypertension and/or diabetes residing in stably low-SES census tracts in 2014 (n = 69,524). We tested associations of census tract gentrification occurring between 2015 and 2019 with participants' disease control in 2019. Secondary analyses considered the role of residential moves (possible displacement), race and ethnicity, and age.

RESULTS

Gentrification exposure was associated with improved odds of hypertension control (aOR: 1.08; 95% CI: 1.00, 1.17), especially among non-Hispanic Whites and adults >65 years. Gentrification was not associated with diabetes control overall, but control improved in the Hispanic subgroup. Disease control was similar regardless of residential moves in the overall sample, but disparate associations emerged in models stratified by race and ethnicity.

CONCLUSIONS

Residents of newly gentrifying neighborhoods may experience modestly improved odds of hypertension and/or diabetes control, but associations may differ across population subgroups.

POLICY IMPLICATIONS

Gentrification may support-or at least not harm-cardiometabolic health for some residents. City leaders and health systems could partner with impacted communities to ensure that neighborhood development meets the goals and health needs of all residents and does not exacerbate health disparities.

Urban health inequality in shifting environment: systematic review on the impact of gentrification on residents' health

The impacts of changing neighborhoods, and the influence of neighborhood stability on residents' health have not received enough attention in the literature; one of the most important aspects is gentrification. Research on the impact of gentrification on residents' health has gradually increased in recent years, mainly from North America. Based on the guidelines of PRISMA 2020 and SCIE, 66 papers were included for analysis, six aspects of selected studies are discussed: the research design, theoretical framework, methods of analysis, definition and measurement of gentrification effects, and impact pathways. In general, most of the literature in this field can be seen as using an ecological research design, of which cross-sectional research accounts for a large proportion. The identified effects vary in their direction as well as strength due to difference in population, temporal, and geographical characteristics. Gentrification could affect health outcomes through the combination of economic, social, and physical environment factors. Existing research could be improved in the following aspects: (1) The definition and measurement of gentrification should be both generic and site-specific; Various measurement methods should be compared to enhance the robustness of the results. Furthermore, more consideration should be given to the impact of spatial issues; (2) As for health outcomes, it is suggested to expand the scope of the discussion of health outcomes and strengthen the biological explanation of the influencing mechanisms. It is also necessary to determine the research time points according to the characteristics of the incubation period of different diseases; (3) As for research design, applying longitudinal research design is more likely to improve the reliability; (4) Theoretical frameworks should be addressed to link the definition and measurement of gentrification, patterns of health outcomes, methodology and pathways.

Racial Disparities in Spine Surgery: A Systematic Review

STUDY DESIGN

Systematic Review.

OBJECTIVES

To synthesize previous studies evaluating racial disparities in spine surgery.

METHODS

We queried PubMed, Embase, Cochrane Library, and Web of Science for literature on racial disparities in spine surgery. Our review was constructed in accordance with Preferred Reporting Items and Meta-analyses guidelines and protocol. The main outcome measures were the occurrence of racial disparities in postoperative outcomes, mortality, surgical management, readmissions, and length of stay.

RESULTS

A total of 1753 publications were assessed. Twenty-two articles met inclusion criteria. Seventeen studies compared Whites (Ws) and African Americans (AAs) groups; 14 studies reported adverse outcomes for AAs. When compared with Ws, AA patients had higher odds of postoperative complications including mortality, cerebrospinal fluid leak, nervous system complications, bleeding, infection, in-hospital complications, adverse discharge disposition, and delay in diagnosis. Further, AAs were found to have increased odds of readmission and longer length of stay. Finally, AAs were found to have higher odds of nonoperative treatment for spinal cord injury, were more likely to undergo posterior approach in the treatment of cervical spondylotic myelopathy, and were less likely to receive cervical disk arthroplasty compared with Ws for similar indications.

CONCLUSIONS

This systematic review of spine literature found that when compared with W patients, AA patients had worse health outcomes. Further investigation of root causes of these racial disparities in spine surgery is warranted.

Race and obesity disparities among adults living in gentrifying neighborhoods

There is a paucity of research seeking to understand race disparities in obesity among individuals living in a gentrifying neighborhood. American Community Survey data were used to identify gentrifying neighborhoods. In a cross-sectional analysis, these data were then linked to the 2014 Medical Expenditure Panel Survey, yielding an analytic sample of 887 Black and White adults. Obesity was based on body mass index ≥ 30 kg/m2. After controlling for potential confounders, Black adults living in gentrifying neighborhoods had a higher prevalence of obesity (PR: 1.39; 95% CI: 1.03, 1.88) than White adults living in gentrifying neighborhoods. Gentrification may have no impact on reducing Black-White obesity disparities in the US.

Neighborhood social organization exposures and racial/ethnic disparities in hypertension risk in Los Angeles

Despite a growing evidence base documenting associations between neighborhood characteristics and the risk of developing high blood pressure, little work has established the role played by neighborhood social organization exposures in racial/ethnic disparities in hypertension risk. There is also ambiguity around prior estimates of neighborhood effects on hypertension prevalence, given the lack of attention paid to individuals' exposures to both residential and nonresidential spaces. This study contributes to the neighborhoods and hypertension literature by using novel longitudinal data from the Los Angeles Family and Neighborhood Survey to construct exposure-weighted measures of neighborhood social organization characteristics-organizational participation and collective efficacy-and examine their associations with hypertension risk, as well as their relative contributions to racial/ethnic differences in hypertension. We also assess whether the hypertension effects of neighborhood social organization vary across our sample of Black, Latino, and White adults. Results from random effects logistic regression models indicate that adults living in neighborhoods where people are highly active in informal and formal organizations have a lower probability of being hypertensive. This protective effect of exposure to neighborhood organizational participation is also significantly stronger for Black adults than Latino and White adults, such that, at high levels of neighborhood organizational participation, the observed Black-White and Black-Latino hypertension differences are substantially reduced to nonsignificance. Nonlinear decomposition results also indicate that almost one-fifth of the Black-White hypertension gap can be explained by differential exposures to neighborhood social organization.

A global cautionary tale: discrimination and violence against trans women worsen despite investments in public resources and improvements in health insurance access and utilization of health care

BACKGROUND

To determine if improvements in social determinants of health for trans women and decreases in transphobic discrimination and violence occurred over three study periods during which extensive local programs were implemented to specifically address longstanding inequities suffered by the transgender community.

METHODS

Interviewer-administered surveys from repeated cross-sectional Transwomen Empowered to Advance Community Health (TEACH) studies in 2010, 2013 and 2016-2017 in San Francisco collected experiences with transphobia violence and discrimination. Respondent-driven sampling was used to obtain a sample of participants who identified as a trans woman.

RESULTS

Violence due to gender identity was prevalent; in each study period, verbal abuse or harassment was reported by over 83% of participants, and physical abuse or harassment was reported by over 56%. Adverse social determinants of health including homelessness, living below the poverty limit, methamphetamine use, depression, PTSD, and anxiety all significantly increased from 2010 to 2016. When testing for trends, housing discrimination and physical violence were both more likely in 2016-2017 compared to the two earlier study periods. Housing discrimination (aOR 1.41, 95% CI 1.00-1.98) and physical violence due to gender identity/presentation (aOR 1.39, 95% CI 1.00-1.92) both significantly increased from 2010 to 2016.

CONCLUSION

Our findings are particularly alarming during a period when significant public health resources and community-based initiatives specifically for trans women were implemented and could have reasonably led us to expect improvements. Despite these efforts, physical violence and housing discrimination among trans women worsened during the study periods. To ensure future improvements, research and interventions need to shift the focus and burden from trans people to cisgender people who are the perpetuators of anti-trans sentiment, stigma, discrimination and victimization.
