The US Preventive Services Task Force (USPSTF) works to improve the health of people nationwide by making evidence-based recommendations for preventive services. Patient-centered care is a core value in US health care. Shared decision-making (SDM), in which patients and clinicians make health decisions together, ensures patients' rights to be informed and involved in preventive care decisions and that these decisions are patient-centered. SDM has a role across the spectrum of USPSTF recommendations. For A or B recommendations (judged by the USPSTF to have high or moderate certainty of a moderate or substantial net benefit at the population level), SDM allows individual patients to decide whether to accept such services based on their personal values and preferences. For C recommendations (indicating at least moderate certainty of a small net benefit at the population level), SDM is critical for individual patients to decide whether the net benefit for them is worthwhile. For D recommendations (reflecting at least moderate certainty of a zero or negative net benefit) or I statements (low certainty of net benefit), clinicians should be prepared to discuss these services if patients ask. More evidence is needed to determine if, in addition to promoting patient-centeredness, SDM reduces inequities in preventive care, as well as to define new strategies to find time for discussion of preventive services in primary care.

Hypertension is an established risk factor for cardiovascular disease. Although controlling blood pressure reduces cardiovascular and stroke mortality and target organ damage, poor blood pressure control remains a clinical and public health challenge. Furthermore, racial and ethnic disparities in the outcomes of hypertension are well documented. In October of 2020, the U.S. Department of Health and Human Services published The Surgeon General's Call to Action to Control Hypertension. The Call to Action emphasized, among other priorities, the need to eliminate disparities in the treatment and control of high blood pressure and to address social determinants as root causes of inequities in blood pressure control and treatment. In support of the goals set in the Call to Action, this review summarizes contemporary research on racial, ethnic, and socioeconomic disparities in hypertension and blood pressure control; describes interventions and policies that have improved blood pressure control in minoritized populations by addressing the social determinants of health; and proposes next steps for achieving equity in hypertension and blood pressure control.

Hypertension treatment and control prevent more cardiovascular events than management of other modifiable risk factors. Although the age-adjusted proportion of US adults with controlled blood pressure (BP) defined as <140/90 mm Hg, improved from 31.8% in 1999-2000 to 48.5% in 2007-2008, it remained stable through 2013-2014 and declined to 43.7% in 2017-2018. To address the rapid decline in hypertension control, the National Heart, Lung, and Blood Institute and the Division for Heart Disease and Stroke Prevention of the Centers for Disease Control and Prevention convened a virtual workshop with multidisciplinary national experts. Also, the group sought to identify opportunities to reverse the adverse trend and further improve hypertension control. The workshop immediately preceded the Surgeon General's Call to Action to Control Hypertension, which recognized a stagnation in progress with hypertension control. The presentations and discussions included potential reasons for the decline and challenges in hypertension control, possible "big ideas," and multisector approaches that could reverse the current trend while addressing knowledge gaps and research priorities. The broad set of "big ideas" was comprised of various activities that may improve hypertension control, including: interventions to engage patients, promotion of self-measured BP monitoring with clinical support, supporting team-based care, implementing telehealth, enhancing community-clinical linkages, advancing precision population health, developing tailored public health messaging, simplifying hypertension treatment, using process and outcomes quality metrics to foster accountability and efficiency, improving access to high-quality health care, addressing social determinants of health, supporting cardiovascular public health and research, and lowering financial barriers to hypertension control.

Although HIV self-testing (HIVST) has expanded in many regions, a few HIVST services have been tailored for and organized by youth. Innovative HIVST models are needed to differentiate testing services and generate local demand for HIVST among youth. The current pilot study aimed at examining the feasibility and efficacy of crowdsourced youth-led strategies to enhance HIVST as well as sexually transmitted infection (STI) testing. Teams of youth iteratively developed HIVST interventions using crowdsourcing approaches and apprenticeship training. Five interventions were selected and then evaluated among youth (ages 14-24) from September 2019 to March 2020. Given the similar outcomes and approaches, we present cumulative data from the completed interventions. We assessed HIVST uptake (self-report), STI uptake (facility reports for gonorrhea, syphilis, hepatitis B, and chlamydia testing), and quality of youth participation. Mixed-effect logistic regression models estimated intervention effects at baseline and 6 months. Of the 388 youths enrolled, 25.3% were aged 14-19, 58.0% were male, and 54.1% had completed secondary education. We observed a significant increase in HIVST from 3 months compared with 6 months (20% vs. 90%; p < 0.001). Among those who received an HIVST at 3 months, 324 out of 388 were re-tested at 6 months. We also observed significant increases in testing for all four STIs: syphilis (5-48%), gonorrhea (5-43%), chlamydia (1-45%), and hepatitis B testing (14-55%) from baseline to the 6-month follow-up. Youth participation in the intervention was robust. Youth-led HIVST intervention approaches were feasible and resulted in increased HIV/STI test uptake. Further research on the effectiveness of these HIVST services is needed.

Importance/UNASSIGNED:Therapeutic inertia may contribute to racial and ethnic differences in blood pressure (BP) control. Objective/UNASSIGNED:To determine the association between race and ethnicity and therapeutic inertia in the Systolic Blood Pressure Intervention Trial (SPRINT). Design, Setting, and Participants/UNASSIGNED:This cross-sectional study was a secondary analysis of data from SPRINT, a randomized clinical trial comparing intensive (<120 mm Hg) vs standard (<140 mm Hg) systolic BP treatment goals. Participants were enrolled between November 8, 2010, and March 15, 2013, with a median follow-up 3.26 years. Participants included adults aged 50 years or older at high risk for cardiovascular disease but without diabetes, previous stroke, or heart failure. The present analysis was restricted to participant visits with measured BP above the target goal. Analyses for the present study were performed in from October 2020 through March 2021. Exposures/UNASSIGNED:Self-reported race and ethnicity, mutually exclusively categorized into groups of Hispanic, non-Hispanic Black, or non-Hispanic White participants. Main Outcomes and Measures/UNASSIGNED:Therapeutic inertia, defined as no antihypertensive medication intensification at each study visit where the BP was above target goal. The association between self-reported race and ethnicity and therapeutic inertia was estimated using generalized estimating equations and stratified by treatment group. Antihypertensive medication use was assessed with pill bottle inventories at each visit. Blood pressure was measured using an automated device. Results/UNASSIGNED:A total of 8556 participants, including 4141 in the standard group (22 844 participant-visits; median age, 67.0 years [IQR, 61.0-76.0 years]; 1467 women [35.4%]) and 4415 in the intensive group (35 453 participant-visits; median age, 67.0 years [IQR, 61.0-76.0 years]; 1584 women [35.9%]) with at least 1 eligible study visit were included in the present analysis. Among non-Hispanic White, non-Hispanic Black, and Hispanic participants, the overall prevalence of therapeutic inertia in the standard vs intensive groups was 59.8% (95% CI, 58.9%-60.7%) vs 56.0% (95% CI, 55.2%-56.7%), 56.8% (95% CI, 54.4%-59.2%) vs 54.5% (95% CI, 52.4%-56.6%), and 59.7% (95% CI, 56.5%-63.0%) vs 51.0% (95% CI, 47.4%-54.5%), respectively. The adjusted odds ratios in the standard and intensive groups for therapeutic inertia associated with non-Hispanic Black vs non-Hispanic White participants were 0.85 (95% CI, 0.79-0.92) and 0.94 (95% CI, 0.88-1.01), respectively. The adjusted odds ratios for therapeutic inertia comparing Hispanic vs non-Hispanic White participants were 1.00 (95% CI, 0.90-1.13) and 0.89 (95% CI, 0.79-1.00) in the standard and intensive groups, respectively. Conclusions and Relevance/UNASSIGNED:Among SPRINT participants above BP target goal, this cross-sectional study found that therapeutic inertia prevalence was similar or lower for non-Hispanic Black and Hispanic participants compared with non-Hispanic White participants. These findings suggest that a standardized approach to BP management, as used in SPRINT, may help ensure equitable care and could reduce the contribution of therapeutic inertia to disparities in hypertension. Trial Registration/UNASSIGNED:ClinicalTrials.gov identifier: NCT01206062.

BACKGROUND:The prevalence of hypertension continues to rise in low- and middle-income- countries (LMICs) where scalable, evidence-based interventions (EBIs) that are designed to reduce morbidity and mortality attributed to hypertension have yet to be fully adopted or disseminated. We sought to evaluate evidence from published randomized controlled trials using EBIs for hypertension control implemented in LMICs, and identify the WHO/ExpandNet scale-up components that are relevant for consideration during "scale-up" implementation planning. METHODS:Systematic review of RCTs reporting EBIs for hypertension control implemented in LMICs that stated "scale-up" or a variation of scale-up; using the following data sources PubMed/Medline, Web of Science Biosis Citation Index (BCI), CINAHL, EMBASE, Global Health, Google Scholar, PsycINFO; the grey literature and clinicaltrials.gov from inception through June 2021 without any restrictions on publication date. Two reviewers independently assessed studies for inclusion, conducted data extraction using the WHO/ExpandNet Scale-up components as a guide and assessed the risk of bias using the Cochrane risk-of-bias tool. We provide intervention characteristics for each EBI, BP results, and other relevant scale-up descriptions. MAIN RESULTS/RESULTS:Thirty-one RCTs were identified and reviewed. Studies reported clinically significant differences in BP, with 23 studies reporting statistically significant mean differences in BP (p < .05) following implementation. Only six studies provided descriptions that captured all of the nine WHO/ExpandNet components. Multi-component interventions, including drug therapy and health education, provided the most benefit to participants. The studies were yet to be scaled and we observed limited reporting on translation of the interventions into existing institutional policy (n = 11), cost-effectiveness analyses (n = 2), and sustainability measurements (n = 3). CONCLUSION/CONCLUSIONS:This study highlights the limited data on intervention scalability for hypertension control in LMICs and demonstrates the need for better scale-up metrics and processes for this setting. TRIAL REGISTRATION/BACKGROUND:Registration PROSPERO (CRD42019117750).

BACKGROUND:Maintaining blood pressure (BP) control over time may contribute to lower risk for cardiovascular disease (CVD) among individuals who are taking antihypertensive medication. METHODS:The Jackson Heart Study (JHS) enrolled 5,306 African-American adults ≥21 years of age and was used to determine the proportion of African Americans that maintain persistent BP control, identify factors associated with persistent BP control, and determine the association of persistent BP control with CVD events. This analysis included 1,604 participants who were taking antihypertensive medication at Visit 1 and had BP data at Visits 1 (2000-2004), 2 (2005-2008), and 3 (2009-2013). Persistent BP control was defined as systolic BP <140 mm Hg and diastolic BP <90 mm Hg at all three visits. CVD events were assessed from Visit 3 through December 31, 2016. Hazard ratios (HR) for the association of persistent BP control with CVD outcomes were adjusted for age, sex, systolic BP, smoking, diabetes, and total and high-density lipoprotein cholesterol at Visit 3. RESULTS:At Visit 1, 1,226 of 1,604 participants (76.4%) with hypertension had controlled BP. Overall, 48.9% of participants taking antihypertensive medication at Visit 1 had persistent BP control. After multivariable adjustment for demographic, socioeconomic, clinical, behavioral, and psychosocial factors, and access-to-care, participants were more likely to have persistent BP control if they were <65 years of age, women, had family income ≥$25,000 at each visit, and visited a health professional in the year prior to each visit. The multivariable adjusted HR (95% confidence interval) comparing participants with versus without persistent BP control was 0.71 (0.46-1.10) for CVD, 0.68 (0.34-1.34) for coronary heart disease, 0.65 (0.27-1.52) for stroke, and 0.55 (0.33-0.90) for heart failure. CONCLUSION/CONCLUSIONS:Less than half of JHS participants taking antihypertensive medication had persistent BP control, putting them at increased risk for heart failure.

Importance/UNASSIGNED:US life expectancy and health outcomes for preventable causes of disease have continued to lag in many populations that experience racism. Objective/UNASSIGNED:To propose iterative changes to US Preventive Services Task Force (USPSTF) processes, methods, and recommendations and enact a commitment to eliminate health inequities for people affected by systemic racism. Design and Evidence/UNASSIGNED:In February 2021, the USPSTF began operational steps in its work to create preventive care recommendations to address the harmful effects of racism. A commissioned methods report was conducted to inform this process. Key findings of the report informed proposed updates to the USPSTF methods to address populations adversely affected by systemic racism and proposed pilots on implementation of the proposed changes. Findings/UNASSIGNED:The USPSTF proposes to consider the opportunity to reduce health inequities when selecting new preventive care topics and prioritizing current topics; seek evidence about the effects of systemic racism and health inequities in all research plans and public comments requested, and integrate available evidence into evidence reviews; and summarize the likely effects of systemic racism and health inequities on clinical preventive services in USPSTF recommendations. The USPSTF will elicit feedback from its partners and experts and proposed changes will be piloted on selected USPSTF topics. Conclusions and Relevance/UNASSIGNED:The USPSTF has developed strategies intended to mitigate the influence of systemic racism in its recommendations. The USPSTF seeks to reduce health inequities and other effects of systemic racism through iterative changes in methods of developing evidence-based recommendations, with partner and public input in the activities to implement the advancements.

Importance:Dental caries is the most common chronic disease in children in the US. According to the 2011-2016 National Health and Nutrition Examination Survey, approximately 23% of children aged 2 to 5 years had dental caries in their primary teeth. Prevalence is higher in Mexican American children (33%) and non-Hispanic Black children (28%) than in non-Hispanic White children (18%). Dental caries in early childhood is associated with pain, loss of teeth, impaired growth, decreased weight gain, negative effects on quality of life, poor school performance, and future dental caries. Objective:To update its 2014 recommendation, the US Preventive Services Task Force (USPSTF) commissioned a systematic review on screening and interventions to prevent dental caries in children younger than 5 years. Population:Asymptomatic children younger than 5 years. Evidence Assessment:The USPSTF concludes with moderate certainty that there is a moderate net benefit of preventing future dental caries with oral fluoride supplementation at recommended doses in children 6 months or older whose water supply is deficient in fluoride. The USPSTF concludes with moderate certainty that there is a moderate net benefit of preventing future dental caries with fluoride varnish application in all children younger than 5 years. The USPSTF concludes that the evidence is insufficient on performing routine oral screening examinations for dental caries by primary care clinicians in children younger than 5 years and that the balance of benefits and harms of screening cannot be determined. Recommendation:The USPSTF recommends that primary care clinicians prescribe oral fluoride supplementation starting at age 6 months for children whose water supply is deficient in fluoride. (B recommendation) The USPSTF recommends that primary care clinicians apply fluoride varnish to the primary teeth of all infants and children starting at the age of primary tooth eruption. (B recommendation) The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of routine screening examinations for dental caries performed by primary care clinicians in children younger than 5 years. (I statement).

BACKGROUND:The American Heart Association created the Life's Simple 7 (LS7) metrics to promote cardiovascular health by achieving optimal levels of blood pressure, cholesterol, blood sugar, physical activity, diet, weight, and smoking status. The degree to which psychosocial factors such as stress and depression impact one's ability to achieve optimal cardiovascular health is unclear, particularly among hypertensive African Americans. METHODS:Cross-sectional analyses included 1,819 African Americans with hypertension participating in the Jackson Heart Study (2000-2004). Outcomes were LS7 composite and individual component scores (defined as poor, intermediate, ideal). High perceived chronic stress was defined as the top quartile of Weekly Stress Inventory scores. High depressive symptoms were defined as Center for Epidemiologic Studies Depression scale scores of ≥16. We compared four groups: high stress alone; high depressive symptoms alone; high stress and high depressive symptoms; low stress and low depressive symptoms (reference) using linear regression for total LS7 scores and logistic regression for LS7 components. RESULTS:Participants with both high stress and depressive symptoms had lower composite LS7 scores (B [95% confidence interval-CI]= -0.34 [-0.65 to -0.02]) than those with low stress and depressive symptoms in unadjusted and age/sex-adjusted models. They also had poorer health status for smoking (OR [95% CI]= 0.52 [0.35-0.78]) and physical activity [OR (95% CI)= 0.71 (0.52-0.95)] after full covariate adjustment. CONCLUSIONS:The combination of high stress and high depressive symptoms was associated with poorer LS7 metrics in hypertensive African Americans. Psychosocial interventions may increase the likelihood of engaging in behaviors that promote optimal cardiovascular health.
