Isolated systolic hypertension (ISH) is a growing health concern in the United States (US) black population. The stratified prevalence of untreated ISH has not been fully investigated in non-Hispanic blacks. Cross-sectional data on 4625 non-Hispanic blacks aged ≥18 years were collected from the National Health and Nutrition Examination Survey 1999-2010, representing a probability sample of the US civilian noninstitutionalized black population. The 6-year prevalence of ISH and 95% confidence intervals (CIs) were estimated by conducting weighted frequency and logistic procedures. The prevalence of untreated ISH was 11.2% among non-Hispanic black adults in 1999-2010. Individuals who received lower education (high school or below) had higher prevalence of untreated ISH than those with higher education (12.8% (95% CI: 11.3-14.2%) vs. 9.0% (95% CI: 7.5-10.6%)). The prevalence of untreated ISH was higher in young men than in young women (4.3% (95% CI: 3.3-5.4%) vs. 1.8% (95% CI: 0.9-2.7%)), and higher in middle-aged adults with lower education than in middle-aged adults with higher education (14.1% (95% CI: 11.4-16.7%) vs. 7.7% (95% CI: 5.5-9.8%)). Compared with 1999-2004, the prevalence of untreated ISH in 2005-2010 decreased for old individuals (27.7% vs. 40.8%), old men (24.4% vs. 40.0%) and old individuals who received higher education (21.4% vs. 40.7%). Untreated ISH is more prevalent in old blacks, and significant reduction of the prevalence in this group suggests that public health interventions, lifestyle modifications or health awareness are in the right direction.

Congestive heart failure (CHF) is associated with a significant economic burden that includes frequent emergency department visits, hospitalizations, and readmissions. The purpose of this study was to examine the differences, if any, between hospital readmission rates and insurance reimbursement rates for non-Hispanic Black and White CHF patients in California. The theoretical framework was Bandura's social cognitive theory. Secondary data for this quantitative study were obtained from the Office of Statewide Health Planning and Development and State Inpatient Databases from Healthcare Cost and Utilization for calendar year 2014-2016. A t-test and Levene's test for equality of variance were conducted on a sample of 11,905 patient records from 675 hospitals in California; the readmission discharge data and insurance reimbursement rates were analyzed by ethnicity and payer type. The results indicated that there was not a statistically significant difference between non-Hispanic Blacks as compared to non-Hispanic Whites in relation to readmission rates (M = 49.6, SD = 38.28) or insurance reimbursement rates (M = 50.88, SD = 36.52). Non-Hispanic Blacks had a higher readmission rate (36%) as compared to Whites (29%), and although these results are not significant, they support the need for healthcare professionals to develop programs that meet the needs of the community. The results of this study contribute to positive social change by providing information that healthcare professionals may be able to use to decrease CHF readmissions and improve access to care for non-Hispanic Blacks and other vulnerable patient groups.

Sexually transmitted infections (STIs) disproportionately impact non-Hispanic blacks in the United States. Racial differences in sexual networks can contribute to these disparities. Racial residential segregation, the separation of racial groups in a residential context, is a community factor known to influence sexual networks and has been associated with negative health outcomes. Our objective was to examine the association between racial residential segregation (henceforth, referred to as segregation), risky sexual behavior, concurrent partnerships, and STI diagnoses among non-Hispanic blacks. Demographic, sexual behavior, and STI diagnosis data for non-Hispanic blacks 15–44 years of age were obtained from the 2006–2010 National Survey of Family Growth. Segregation and community poverty data were obtained from the U.S. Census. Five distinct dimensions measured segregation, each with a representative index. Multilevel logistic regressions were conducted to test how each of the five indices were associated with risky sexual behavior, concurrent partnerships, and STI diagnoses. Risky sexual behavior results showed 16.1% (n=588) of participants engaged in risky sexual behavior. The association was stronger for the absolute centralization (adjusted odds ratio [aOR] 2.07; 95% confidence interval [CI] 2.05 – 2.08) and relative concentration indices (aOR 2.05; 95% CI 2.03 – 2.07). This suggests risky sexual behavior is most strongly associated with segregation in neighborhoods with a high density of non-Hispanic blacks and accumulation of non-Hispanic blacks in an urban core. STI diagnosis results showed 7.4% (n=305) of participants reported a STI diagnosis, and segregation was associated with STI diagnosis. The association was strongest measured with the dissimilarity index (aOR 2.41; 95% CI 2.38 – 2.43) and stronger for males. Concurrent partnerships results showed 15.6% (n=645) of participants reported concurrent partnerships. Multilevel analyses showed segregation to be associated with concurrent partnerships with the association strongest measured with the dissimilarity index. Segregation acted as a risk and a protective factor with risky sexual behavior, concurrent partnerships, and STI diagnosis, depending on the segregation measure. Additional work is needed to understand the mechanisms of how specific segregation dimensions influence risky sexual behaviors and sexually transmitted infections.
