This study sought to establish the psychometric properties of a Coping Strategies Inventory Short Form (CSI-SF) by examining coping skills in the Jackson Heart Study cohort. We used exploratory and confirmatory factor analysis, Pearson’s correlation, and Cronbach Alpha to examine reliability and validity in the CSI-SF that solicited responses from 5302 African American men and women between the ages of 35 and 84. One item was dropped from the 16-item CSI-SF, making it a 15-item survey. No significant effects were found for age and gender, strengthening the generalizability of the CSI-SF. The internal consistency reliability analysis revealed reliability between alpha = 0.58–0.72 for all of the scales, and all of the fit indices used to examine the CSI-SF provided support for its use as an adequate measure of coping. This study provides empirical support for utilizing this instrument in future efforts to understand the role of coping in moderating health outcomes.

Tobacco and alcohol use are heritable behaviours associated with 15% and 5.3% of worldwide deaths, respectively, due largely to broad increased risk for disease and injury1–4. These substances are used across the globe, yet genome-wide association studies have focused largely on individuals of European ancestries5. Here we leveraged global genetic diversity across 3.4 million individuals from four major clines of global ancestry (approximately 21% non-European) to power the discovery and fine-mapping of genomic loci associated with tobacco and alcohol use, to inform function of these loci via ancestry-aware transcriptome-wide association studies, and to evaluate the genetic architecture and predictive power of polygenic risk within and across populations. We found that increases in sample size and genetic diversity improved locus identification and fine-mapping resolution, and that a large majority of the 3,823 associated variants (from 2,143 loci) showed consistent effect sizes across ancestry dimensions. However, polygenic risk scores developed in one ancestry performed poorly in others, highlighting the continued need to increase sample sizes of diverse ancestries to realize any potential benefit of polygenic prediction.

IntroductionApproximately 26.3 million people in the United States have chronic kidney disease and many more are at risk of developing the condition. The association between specific metabolic syndrome components and chronic kidney disease in African American individuals is uncertain.MethodsBaseline data from 4,933 participants of the Jackson Heart Study were analyzed. Logistic regression models were used to estimate the odds and 95% confidence intervals of chronic kidney disease associated with individual components, metabolic syndrome, the number of components, and specific combinations of metabolic syndrome components.ResultsMetabolic syndrome was common with a prevalence of 42.0%. Chronic kidney disease was present in 19.4% of participants. The prevalence of metabolic components was high: elevated blood pressure (71.8%), abdominal obesity (65.8%), low fasting high density lipoprotein cholesterol (37.3%), elevated fasting glucose (32.2%) and elevated triglycerides (16.2%). Elevated blood pressure, triglycerides, fasting blood glucose, and abdominal obesity were significantly associated with increased odds of chronic kidney disease. Participants with metabolic syndrome had a 2.22-fold (adjusted odds ratio (AOR) 2.22; 95% CI, 1.78–2.78) increase in the odds of chronic kidney disease compared to participants without metabolic syndrome. The combination of elevated fasting glucose, elevated triglycerides, and abdominal obesity was associated with the highest odds for chronic kidney disease (AOR 25.11; 95% CI, 6.94–90.90).ConclusionMetabolic syndrome as well as individual or combinations of metabolic syndrome components are independently associated with chronic kidney disease in African American adults.

Building Collaborative Health Promotion Partnerships: The Jackson Heart Study. Background: Building a collaborative health promotion partnership that effectively employs principles of community-based participatory research (CBPR) involves many dimensions. To ensure that changes would be long-lasting, it is imperative that partnerships be configured to include groups of diverse community representatives who can develop a vision for long-term change. This project sought to enumerate processes used by the Jackson Heart Study (JHS) Community Outreach Center (CORC) to create strong, viable partnerships that produce lasting change. Methods: JHS CORC joined with community representatives to initiate programs that evolved into comprehensive strategies for addressing health disparities and the high prevalence of cardiovascular disease (CVD). This collaboration was made possible by first promoting an understanding of the need for combined effort, the desire to interact with other community partners, and the vision to establish an effective governance structure. Results: The partnership between JHS CORC and the community has empowered and inspired community members to provide leadership to other health promotion projects. Conclusion: Academic institutions must reach out to local community groups and together address local health issues that affect the community. When a community understands the need for change to respond to negative health conditions, formalizing this type of collaboration is a step in the right direction.

Background: History has recorded the tremendous concerns and apprehension expressed by African Americans about participating in research studies. This review enumerates the collaborative techniques that were utilized by the Jackson State University (JSU) Jackson Heart Study (JHS) community-focused team to facilitate recruitment and retention of the JHS cohort and to implement health education and health promotion in the JHS communities. Methods: This review describes the evolution of the JSU JHS community initiatives, an innovative community-driven operation, during the period 1999–2018. Results: JSU JHS community-focused investigators published approximately 20 manuscripts, including community-led research and publications with community lead authors and co-authors, research and publications in collaboration with other JHS staff, through other JSU-funded projects. The JSU JHS community-focused unit also initiated the JHS Community Training Activities, developed the Community Health Advisory Network (CHAN), and trained and certified 137 Community Health Advisors. In addition, the JSU JHS community-focused unit developed the Collaborative Community Science Model (CCSM) that symbolized its approach to community engagement and outreach, and a Trust Scale for ascertaining African Americans’ willingness to engage in biomedical research collaborations. Conclusion: This review offers educators, public health professionals, and research investigators a useful starting point for the development, selection, or improvement of techniques to motivate, inspire, and engage community residents in a community–academia partnership that yielded maximum benefits in the areas of health education, health promotion and interventions, and biomedical research. Substantial, meaningful community engagement is possible when prioritizing elimination of health disparities and long-term improvement in health care access in the target populations.

This study examined: (a) differences in lung function between current and non current smokers who had sedentary lifestyles and non sedentary lifestyles and (b) the mediating effect of sedentary lifestyle on the association between smoking and lung function in African Americans. Sedentary lifestyle was defined as the lowest quartile of the total physical activity score. The results of linear and logistic regression analyses revealed that non smokers with non sedentary lifestyles had the highest level of lung function, and smokers with sedentary lifestyles had the lowest level. The female non-smokers with sedentary lifestyles had a significantly higher FEV1% predicted and FVC% predicted than smokers with non sedentary lifestyles (93.3% vs. 88.6%; p = 0.0102 and 92.1% vs. 86.9%; p = 0.0055 respectively). FEV1/FVC ratio for men was higher in non smokers with sedentary lifestyles than in smokers with non sedentary lifestyles (80.9 vs. 78.1; p = 0.0048). Though smoking is inversely associated with lung function, it seems to have a more deleterious effect than sedentary lifestyle on lung function. Physically active smokers had higher lung function than their non physically active counterparts.

This study examined the diet quality of the school meals in two Mississippi school districts and compared them to the national guidelines. We examined the lunch menus of the two school districts that participated in the National School Lunch Program and School Breakfast Program focusing on food quality and assessing both healthy and unhealthy foods and eating behaviors. This analysis was completed through a computerized review used to accurately determine the nutrient content. Both the standard and the alternative meals provided by the cafeterias in the two school districts exceeded the minimum requirement for calories for all grade levels. The meals from the urban schools cafeteria provide more calories than meals from the cafeteria in the rural school district. Although schools believe that they are making positive changes to children’s diets, the programs are falling short of the nutrient recommendations. Poor nutrition and improper dietary practices are now regarded as important risk factors in the emerging problems of obesity, diabetes mellitus, hypertension and other chronic diseases, with excessive energy intake listed as a possible reason. Dieticians, school professionals and other health care practitioners need to accurately assess energy intake and adequately promote a dietary responsible lifestyle among children.
