Traditional methods of health surveillance often under-represent racial and ethnic minorities. Our objective was to use geospatial analysis and emergency claims data to estimate local chronic disease prevalence separately for specific racial and ethnic groups. We also performed a regression analysis to identify associations between median household income and local disease prevalence among Black, Hispanic, Asian, and White adults in New York City. The study population included individuals who visited an emergency department at least once from 2009 to 2013. Our main outcomes were geospatial estimates of diabetes, hypertension, and asthma prevalence by Census tract as stratified by race and ethnicity. Using emergency claims data, we identified 4.9 million unique New York City adults with 28.5% of identifying as Black, 25.2% Hispanic, and 6.1% Asian. Age-adjusted disease prevalence was highest among Black and Hispanic adults for diabetes (13.4 and 13.1%), hypertension (28.7 and 24.1%), and asthma (9.9 and 10.1%). Correlation between disease prevalence maps demonstrated moderate overlap between Black and Hispanic adults for diabetes (0.49), hypertension (0.57), and asthma (0.58). In our regression analysis, we found that the association between low income and high disease prevalence was strongest for Hispanic adults, whereas increases in income had more modest reductions in disease prevalence for Black adults, especially for diabetes. Our geographically detailed maps of disease prevalence generate actionable evidence that can help direct health interventions to those communities with the highest health disparities. Using these novel geographic approaches, we reveal the underlying epidemiology of chronic disease for a racially and culturally diverse population.

There is a significant evidence base for the Diabetes Prevention Program, a lifestyle intervention to prevent onset of type 2 diabetes among high-risk individuals; however, translation of this intervention for men has been challenging. This report presents outcomes of the pilot study of an adapted 16-week diabetes prevention program entitled " Power Up for Health." The study goal was to better engage men of color with prediabetes from disadvantaged neighborhoods of New York City. It was implemented at five different recreation centers located in predominantly low-income neighborhoods across New York City. The curriculum was facilitated by male lifestyle coaches only; one group was conducted in Spanish. Primary outcome was weight loss from baseline to 16 weeks. Other measures included lifestyle activities, depressive symptoms, and self-reported health status. Men ( N = 47) were screened by telephone. Of the 29 eligible men who began the program, 25 attended at least 4 sessions (52% non-Latino Black, 32% Latino, mean age 51.7 ± SD 9.9 years, mean body mass index 35 ± SD 6.9 kg/m²). End of program outcomes ( n = 23) varied by site and included a mean weight loss of 3.8% (9.7 lbs); 3 of the 5 sites had a mean weight loss of 5.6%, meeting the national goal of 5%-7%. Men ( n = 23) attended a mean of 11.6 of 16 sessions. Improvement in depressive symptoms, healthy eating and exercise, and health status were also seen. While recruitment was challenging with many lessons learned, the adapted men's diabetes prevention program shows promise of success for participants and their coaches.

This article explores the role the Black Church could play in facilitating spiritually sensitive, culturally relevant and gender-specific services to address the mental health and well-being of Black males. The help-seeking behaviors of Black men are examined as the authors offer two theories: the body, mind, spirit, environment, social, transcendent, and health, illness, men, and masculinities that may assist the Black Church in functioning as an effective support networks for healthy Black male mental health. Next, the authors discuss implications for practice, research, and education, and lastly, eight recommendations for Black Church leadership, social workers, and mental health professionals are also discussed.

Geographic surveillance can identify hotspots of disease and reveal associations between health and the environment. Our study used emergency department surveillance to investigate geographic disparities in type 1 and type 2 diabetes prevalence among adults and children. Using all-payer emergency claims data from 2009 to 2013, we identified unique New York City residents with diabetes and geocoded their location using home addresses. Geospatial analysis was performed to estimate diabetes prevalence by New York City Census tract. We also used multivariable regression to identify neighborhood-level factors associated with higher diabetes prevalence. We estimated type 1 and type 2 diabetes prevalence at 0.23% and 10.5%, respectively, among adults and 0.20% and 0.11%, respectively, among children in New York City. Pediatric type 1 diabetes was associated with higher income (P = 0.001), whereas adult type 2 diabetes was associated with lower income (P < 0.001). Areas with a higher proportion of nearby restaurants categorized as fast food had a higher prevalence of all types of diabetes (P < 0.001) except for pediatric type 2 diabetes. Type 2 diabetes among children was only higher in neighborhoods with higher proportions of African American residents (P < 0.001). Our findings identify geographic disparities in diabetes prevalence that may require special attention to address the specific needs of adults and children living in these areas. Our results suggest that the food environment may be associated with higher type 1 diabetes prevalence. However, our analysis did not find a robust association with the food environment and pediatric type 2 diabetes, which was predominantly focused in African American neighborhoods.

Cardiovascular disparities remain pervasive in the United States. Unequal disease burden is evident among population groups based on sex, race, ethnicity, socioeconomic status, educational attainment, nativity, or geography. Despite the significant declines in cardiovascular disease mortality rates in all demographic groups during the last 50 years, large disparities remain by sex, race, ethnicity, and geography. Recent data from modeling studies, linked micromap plots, and small-area analyses also demonstrate prominent variation in cardiovascular disease mortality rates across states and counties, with an especially high disease burden in the southeastern United States and Appalachia. Despite these continued disparities, few large-scale intervention studies have been conducted in these high-burden populations to examine the feasibility of reducing or eliminating cardiovascular disparities. To address this challenge, on June 22 and 23, 2017, the National Heart, Lung, and Blood Institute convened experts from a broad range of biomedical, behavioral, environmental, implementation, and social science backgrounds to summarize the current state of knowledge of cardiovascular disease disparities and propose intervention strategies aligned with the National Heart, Lung, and Blood Institute mission. This report presents the themes, challenges, opportunities, available resources, and recommended actions discussed at the workshop.

Introduction/UNASSIGNED:Sleep disturbance is a major public health issue and is comorbid with the cluster of conditions associated with metabolic syndrome (MetS). Our study explored the presence of sleep disturbance, including daytime sleepiness, the risk for obstructive sleep apnea (OSA), and insomnia symptoms, in a cohort of adult Black men and women with MetS. Methods/UNASSIGNED:Patients (n=1,013) from the Metabolic Syndrome Outcome Study (MetSO), 2009-2012, met criteria for MetS based on guidelines from the National Cholesterol Education Program's Adult Treatment Panel and provided sociodemographic data and the Apnea Risk Evaluation System (ARES) questionnaire to assess OSA risk, sleep characteristics, and physician-reported diagnosis of a sleep disorder. Results/UNASSIGNED:Prevalence of the components of MetS included: diabetes (60%); obesity (67%); hypertension (94%); and dyslipidemia (74%). Based on the ARES, 49% were at risk for OSA. Of all study patients, slightly more than half (53%) reported feeling sleepy during the day, and 10% reported an insomnia diagnosis. The most common sleep disturbance reported by 46% of the patients was early morning awakenings (EMA). This was closely followed by 42% who reported difficulty staying asleep (DSA) and 38% reporting difficulty falling asleep (DFA). Seventy percent reported short sleep (≤ 6 hours), whereas a minority (19%) reported long sleep (≥ 9 hours). Only 12% used sleep aids. Women, compared with men, reported greater daytime sleepiness, greater DFA, and greater DSA (57% vs 45%; 41% vs 32.4%; 45% vs 37%), respectively. Conclusion/UNASSIGNED:Blacks with MetS reported insomnia symptoms and insomnia disorder, use of sleep aids, feeling sleepy during the day, and inadequate sleep durations. The presence of these sleep characteristics suggests that patients with MetS should be referred for further sleep assessment.

OBJECTIVES: To test the effectiveness of a preclinical, telephone-based patient navigation intervention to encourage colorectal cancer (CRC) screening among older Black men. METHODS: We conducted a 3-parallel-arm, randomized trial among 731 self-identified Black men recruited at barbershops between 2010 and 2013 in New York City. Participants had to be aged 50 years or older, not be up-to-date on CRC screening, have uncontrolled high blood pressure, and have a working telephone. We randomized participants to 1 of 3 groups: (1) patient navigation by a community health worker for CRC screening (PN), (2) motivational interviewing for blood pressure control by a trained counselor (MINT), or (3) both interventions (PLUS). We assessed CRC screening completion at 6-month follow-up. RESULTS: Intent-to-treat analysis revealed that participants in the navigation interventions were significantly more likely than those in the MINT-only group to be screened for CRC during the 6-month study period (17.5% of participants in PN, 17.8% in PLUS, 8.4% in MINT; P < .01). CONCLUSIONS: Telephone-based preclinical patient navigation has the potential to be effective for older Black men. Our results indicate the importance of community-based health interventions for improving health among minority men. (Am J Public Health.

Background -Data from before the 2000s indicate the majority of incident cardiovascular disease (CVD) events occur among US adults with systolic and diastolic blood pressure (SBP/DBP)>/=140/90 mmHg. Over the past several decades, BP declined and hypertension control has improved. Methods -We estimated the percentage of incident CVD events that occur at SBP/DBP<140/90 mmHg in a pooled analysis of three contemporary US cohorts: the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study, the Multi-Ethnic Study of Atherosclerosis (MESA), and the Jackson Heart Study (JHS) (n=31,856; REGARDS=21,208; MESA=6,779; JHS=3,869). Baseline study visits were conducted in 2003-2007 for REGARDS, 2000-2002 for MESA, and 2000-2004 for JHS. BP was measured by trained staff using standardized methods. Antihypertensive medication use was self-reported. The primary outcome was incident CVD, defined by the first occurrence of fatal or non-fatal stroke, non-fatal myocardial infarction, fatal coronary heart disease, or heart failure. Events were adjudicated in each study. Results -Over a mean follow-up of 7.7 years, 2,584 participants had incident CVD events. Overall, 63.0% (95%CI: 54.9%-71.1%) of events occurred in participants with SBP/DBP<140/90 mmHg; 58.4% (95%CI: 47.7%-69.2%) and 68.1% (95%CI: 60.1%-76.0%) among those taking and not taking antihypertensive medication, respectively. The majority of events occurred in participants with SBP/DBP<140/90 mmHg among those <65 years (66.7%; 95%CI: 60.5%-73.0%) and >/=65 years (60.3%; 95%CI: 51.0%-69.5%), women (61.4%; 95%CI: 49.9%-72.9%) and men (63.8%; 95%CI: 58.4%-69.1%), and for whites (68.7%; 95%CI: 66.1%-71.3%), blacks (59.0%; 95%CI: 49.5%-68.6%), Hispanics (52.7% 95%CI: 45.1%-60.4%) and Chinese-Americans (58.5%; 95%CI: 45.2%-71.8%). Among participants taking antihypertensive medication with SBP/DBP<140/90 mmHg, 76.6% (95% CI: 75.8%-77.5%) were eligible for statin treatment but only 33.2% (95%CI: 32.1%-34.3%) were taking one and 19.5% (95%CI: 18.5%-20.5%) met the Systolic Blood Pressure Intervention Trial eligibility criteria and may benefit from a SBP target goal of 120 mmHg. Conclusions -While higher BP levels are associated with increased CVD risk, in the modern era, the majority of incident CVD events occur in US adults with SBP/DBP<140/90 mmHg. Although absolute risk and cost-effectiveness should be considered, additional CVD risk reduction measures for adults with SBP/DBP<140/90 mmHg at high risk for CVD may be warranted.

Background -Ambulatory blood pressure (BP) monitoring (ABPM) is the reference standard for out-of-clinic BP measurement. Thresholds for identifying ambulatory hypertension (daytime systolic BP [SBP]/diastolic BP [DBP] >/= 135/85 mmHg, 24-hour SBP/DBP >/= 130/80 mmHg, and nighttime SBP/DBP >/= 120/70 mmHg) have been derived from European, Asian and South American populations. We determined BP thresholds for ambulatory hypertension in a US population-based sample of African Americans. Methods -We analyzed data from the Jackson Heart Study (JHS), a population-based cohort study comprised exclusively of African-American adults (n=5,306). Analyses were restricted to 1,016 participants who completed ABPM at baseline in 2000-2004. Mean systolic BP (SBP) and diastolic BP (DBP) levels were calculated for daytime (10:00am-8:00pm), 24-hour (all available readings) and nighttime (midnight-6:00am) periods, separately. Daytime, 24-hour, and nighttime BP thresholds for ambulatory hypertension were identified using regression- and outcome-derived approaches. The composite of a cardiovascular disease (CVD) or all-cause mortality event was used in the outcome-derived approach. For this latter approach, BP thresholds were identified only for SBP as clinic DBP was not associated with the outcome. Analyses were stratified by antihypertensive medication use. Results -Among participants not taking antihypertensive medication, the regression-derived thresholds for daytime, 24-hour, and nighttime SBP/DBP corresponding to clinic SBP/DBP of 140/90 mmHg were 134/85 mmHg, 130/81 mmHg, and 123/73 mmHg, respectively. The outcome-derived thresholds for daytime, 24-hour, and nighttime SBP corresponding to a clinic SBP >/= 140 mmHg were 138 mmHg, 134 mmHg, and 129 mmHg, respectively. Among participants taking antihypertensive medication, the regression-derived thresholds for daytime, 24-hour, and nighttime SBP/DBP corresponding to clinic SBP/DBP of 140/90 mmHg were 135/85 mmHg, 133/82 mmHg, and 128/76 mmHg, respectively. The corresponding outcome-derived thresholds for daytime, 24-hour, and nighttime SBP were 140 mmHg, 137 mmHg, and 133 mmHg, respectively, among those taking antihypertensive medication. Conclusions -Based on the outcome-derived approach for SBP and regression-derived approach for DBP, the following definitions for daytime hypertension, 24-hour hypertension, and nighttime hypertension corresponding to clinic SBP/DBP >/= 140/90 mmHg are proposed for African Americans: daytime SBP/DBP >/= 140/85 mmHg, 24-hour SBP/DBP >/= 135/80 mmHg, and nighttime SBP/DBP >/= 130/75 mmHg, respectively.
