Background: We examined the association of multilevel social determinants of health with incident apparent treatment-resistant hypertension (aTRH)., Methods and Results: We analyzed data from 2774 White and 2257 Black US adults from the REGARDS (Reasons for Geographic and Racial Differences in Stroke) study taking antihypertensive medication without aTRH at baseline to estimate the association of social determinants of health with incident aTRH. Selection of social determinants of health was guided by the Healthy People 2030 domains of education, economic stability, social context, neighborhood environment, and health care access. Blood pressure (BP) was measured during study visits, and antihypertensive medication classes were identified through a pill bottle review. Incident aTRH was defined as (1) systolic BP ≥140 mm Hg or diastolic BP ≥90 mm Hg, or systolic BP ≥130 mm Hg or diastolic BP ≥80 mm Hg for those with diabetes or chronic kidney disease while taking ≥3 classes of antihypertensive medication or (2) taking ≥4 classes of antihypertensive medication regardless of BP level, at the follow-up visit. Over a median 9.5 years of follow-up, 15.9% of White and 24.0% of Black adults developed aTRH. A percent of the excess aTRH risk among Black versus White adults was mediated by low education (14.2%), low income (16.0%), not seeing a friend or relative in the past month (8.1%), not having someone to care for them if ill or disabled (7.6%), lack of health insurance (10.6%), living in a disadvantaged neighborhood (18.0%), and living in states with poor public health infrastructure (6.0%)., Conclusions: Part of the association between race and incident aTRH risk was mediated by social determinants of health.

Background: A high proportion of individuals with HIV have hypertension, and the incidence of cardiovascular disease (CVD) is high in individuals with HIV., Methods: We determined if the association between hypertension and CVD, including acute myocardial infarction (AMI), stroke, and heart failure, differs between individuals with and without HIV. We analyzed data for 108 980 adults with HIV matched (1:4) to 435 920 adults without HIV in 2011 to 2019 from the Marketscan database, which includes US adults with health insurance. The primary outcome, incident CVD, defined by an AMI, stroke or heart failure, was identified using validated claims-based algorithms., Results: Over a median follow-up of 2.3 years, there were 4027 CVD events, including 2345 AMI, 1153 stroke, and 684 heart failure events. After multivariable adjustment, the hazard ratio for CVD associated with hypertension was 1.56 (95% CI, 1.44-1.69) among individuals without HIV and 1.73 (95% CI, 1.52-1.96) among individuals with HIV ( P value for interaction=0.159). The multivariable-adjusted hazard ratio for AMI associated with hypertension was 1.35 (95% CI, 1.22-1.51) among individuals without HIV and 1.70 (95% CI, 1.44-2.01) among individuals with HIV ( P value for interaction=0.017). Hypertension was associated with stroke and heart failure among individuals without and with HIV with no evidence of effect modification ( P value for interaction >0.40)., Conclusions: Hypertension was associated with increased CVD, AMI, stroke, and heart failure risk among individuals with and without HIV, with a stronger association for AMI among individuals with versus without HIV. This study emphasizes the high CVD risk associated with hypertension among individuals with HIV.

COVID-19 has disproportionately affected persons who identify as non-Hispanic American Indian or Alaska Native (AI/AN) (1). The Blackfeet Tribal Reservation, the northern Montana home of the sovereign Blackfeet Nation, with an estimated population of 10,629 (2), detected the first COVID-19 case in the community on June 16, 2020. Following CDC guidance,* and with free testing widely available, the Indian Health Service and Blackfeet Tribal Health Department began investigating all confirmed cases and their contacts on June 25. The relationship between three community mitigation resolutions passed and enforced by the Blackfeet Tribal Business Council and changes in the daily COVID-19 incidence and in the distributions of new cases was assessed. After the September 28 issuance of a strictly enforced stay-at-home order and adoption of a mask use resolution, COVID-19 incidence in the Blackfeet Tribal Reservation decreased by a factor of 33 from its peak of 6.40 cases per 1,000 residents per day on October 5 to 0.19 on November 7. Other mitigation measures the Blackfeet Tribal Reservation used included closing the east gate of Glacier National Park for the summer tourism season, instituting remote learning for public school students throughout the fall semester, and providing a Thanksgiving meal to every household to reduce trips to grocery stores. CDC has recommended use of routine public health interventions for infectious diseases, including case investigation with prompt isolation, contact tracing, and immediate quarantine after exposure to prevent and control transmission of SARS-CoV-2, the virus that causes COVID-19 (3). Stay-at-home orders, physical distancing, and mask wearing indoors, outdoors when physical distancing is not possible, or when in close contact with infected or exposed persons are also recommended as nonpharmaceutical community mitigation measures (3,4). Implementation and strict enforcement of stay-at-home orders and a mask use mandate likely helped reduce the spread of COVID-19 in the Blackfeet Tribal Reservation., Competing Interests: All authors have completed and submitted the International Committee of Medical Journal Editors form for disclosure of potential conflicts of interest. No potential conflicts of interest were disclosed.

The current study assesses the intercoder reliability of one of the most important skin tone measurement instruments-the Massey-Martin scale. This scale is used in several high-profile social surveys, but has not yet been psychometrically evaluated. The current evaluation is only possible because, for the first time, the General Social Survey's 2010-2014 panel used the instrument to guide interviewers' skin tone observation of the same respondents in two different years (2012 and 2014). Despite the widespread use of the Massey-Martin scale to investigate potential effects of skin tone on social attitudes and outcomes, the data suggest that the measure has low intercoder reliability. Implications for researchers and survey practitioners are discussed.

This study examines the association of neighborhood environment, as measured by housing factors, with physical activity among older African Americans. Context is provided on the effects of structural inequality as an inhibitor of health enhancing neighborhood environments. The study population included African Americans participating in the UAB Study of Aging (n=433). Participants demonstrated the ability to walk during a baseline in-home assessment. The strength and independence of housing factors were assessed using neighborhood walking for exercise as the outcome variable. Sociodemographic data, co-morbid medical conditions, and rural/urban residence were included as independent control factors. Homeownership, occupancy, and length of residency maintained positive associations with neighborhood walking independent of control factors. Housing factors appear to be predictive of resident engagement in neighborhood walking. Housing factors, specifically high rates of homeownership, reflect functional and positive neighborhood environments conducive for physical activity. Future interventions seeking to promote health-enhancing behavior should focus on developing housing and built-environment assets within the neighborhood environment.
