Background: Chronic low-grade inflammation reflects a subclinical immune response implicated in the pathogenesis of complex diseases. Identifying genetic loci where DNA methylation is associated with chronic low-grade inflammation may reveal novel pathways or therapeutic targets for inflammation.

Results: We performed a meta-analysis of epigenome-wide association studies (EWAS) of serum C-reactive protein (CRP), which is a sensitive marker of low-grade inflammation, in a large European population (n = 8863) and trans-ethnic replication in African Americans (n = 4111). We found differential methylation at 218 CpG sites to be associated with CRP (P < 1.15 × 10^–7) in the discovery panel …

Correlates Of Sexual-Risk Behaviors Among Young Black Msm: Implications For Clinic-Based Counseling Programs, Richard A. Crosby, Leandro Mena, Janelle M. Ricks

Health, Behavior & Society Faculty Publications

This study applied an 8-item index of recent sexual-risk behaviors to young Black men who have sex with men (YBMSM) and evaluated the distribution for normality. The distribution was tested for associations with possible antecedents of sexual risk. YBMSM (N = 600), aged 16–29 years, were recruited from a sexually transmitted infection clinic, located in the southern US. Men completed an extensive audio computer-assisted self-interview. Thirteen possible antecedents of sexual risk, as assessed by the index, were selected for analyses. The 8-item index formed a normal distribution with a mean of 4.77 (SD = 1.77). In adjusted analyses, not …

Circumcision Status Is Not Associated With Condom Use And Prevalence Of Sexually Transmitted Infections Among Young Black Msm, Richard A. Crosby, Cynthia A. Graham, Leandro Mena, William L. Yarber, Stephanie A. Sanders, Robin R. Milhausen, Angelica Geter

Health, Behavior & Society Faculty Publications

This study investigated whether intact young Black MSM differed from their circumcised counterparts regarding condom use behaviors and perceptions and HIV/Chlamydia/gonorrhea. Young Black MSM completed a self-interview, including a pictorial item assessing circumcision status and measures of condom use. Twenty-seven percent of 388 participants reported not being circumcised. With one exception, no associations tested approached significance. The mean frequency of unprotected insertive anal sex for circumcised men was about twice as high compared to those intact (P = .04). Intact young Black MSM did not differ from circumcised men relative to prevalence of STIs (including HIV) or condom use behaviors …

Perceptions Of Renal Disease Risk Among African Americans: A Review Of The Literature, Casey L. Migliore, Julie Barroso, Allison Vorderstrasse

Journal of Health Disparities Research and Practice

African Americans are disproportionately at risk for renal disease, especially those with type 2 diabetes (McDonough et al., 2011). Despite this disease disparity, the literature lacks research on renal disease awareness and risk perceptions among African Americans with type 2 diabetes. Therefore, a literature review guided by the Common Sense Model was conducted to review and synthesize the literature on African Americans’ awareness of renal disease and existing risk perceptions, capturing sociocultural factors in the African American community that could influence the development of those risk perceptions. The literature identified an overall lack of knowledge about renal disease risk factors, …

Similarities And Differences In Sexual Risk Behaviors Between Young Black Msm Who Do And Do Not Have Sex With Females, Richard A. Crosby, Leandro Mena, Angelica Geter, Demarc Hickson

Health, Behavior & Society Faculty Publications

The objective of this study is to determine whether young Black MSM who also have sex with females report similar levels of sexual risk behaviors as those not having sex with females. YBMSM (N = 400) were recruited from an STI clinic, located in the Southern U.S. Men completed an audio-computer assisted self-interview and donated specimens for STI/HIV testing. Forty-three percent recently engaged in penile-vaginal sex. They were less likely to report having concurrent partners (P = .01), unprotected fellatio (P = .04), multiple partners as a bottom (P < .02), any unprotected anal sex as a bottom (P < .013), and any anal sex (P = .007). They were equally likely …

Faculty Publications & Research of the TUC College of Osteopathic Medicine

Using a modified social ecological model, we conducted a review of the literature and nationwide statistics on African American health. We discuss the main social determinants of health and main health disparities, risk factors, the leading causes of morbidity and mortality, and access to health services for blacks in the USA. The mechanisms through which social determinants, including racism, exert their deleterious effects on black health are discussed at the macro and individual levels. Incarceration and mental health care issues are highlighted as priorities to be addressed. African Americans remain the least healthy ethnic group in the USA, a somber …

African Americans' Understanding Of The Provisions Of The Affordable Care Act, Ewang Theo Epie-Alobwede

Walden Dissertations and Doctoral Studies

African Americans as a group tend to have numerous health issues, and by the time they seek healthcare, the conditions often advance into more serious ailments. Researchers have shown that cultural distrust of the U.S. healthcare system coupled with some discriminatory practices has hindered African Americans seeking care and taking full advantage of the healthcare system. With the introduction of the Patient Protection and Affordable Care Act (ACA), there is some confusion about the application of the law, resulting in many intended beneficiaries misinterpreting it, and not accessing quality healthcare. This interpretive phenomenological study explored how African Americans in the …

Admixture Mapping Of Subclinical And Clinical Cardiovascular Disease Among African Americans, Aditi Shendre

All ETDs from UAB

The purpose of this dissertation is to evaluate the association of local European ancestry (LEA) with subclinical and clinical cardiovascular (CV) disease (CVD) among African Americans in three prospective cohorts from the United States. CVD burden is higher among African Americans compared to other racial/ethnic groups and prevention efforts have led to the evaluation of subclinical measures of CVD such as carotid artery intima-media thickness (CIMT), and risk factors including the underlying genetic component of the disease. Admixed populations such as African Americans may have increased risk of disease as a result of the increased prevalence of a disease among …

Communicating Social Support: Understanding Complexities Of Breastfeeding Communication Among African American Mothers, Nicole Rachael Peritore

Theses and Dissertations--Communication

Breast milk is the best choice for meeting the nutritional needs for an infant whenever possible. Despite the knowledge that this nutritional choice is the best choice for an infant, data demonstrates that there is a sharp decline in the rates of breastfeeding mothers. Among African Americans, breastfeeding rates are significantly lower than the national averages. Despite many of the applications of social support in communication research, there is a gap in knowledge on the social support systems in the context of breastfeeding, especially for African Americans. With the social ecological model as a framework, social support theory provides understanding …
