Biomarkers of selenium are necessary for assessing selenium status in humans, since soil variation hinders estimation of selenium intake from foods. In this study, we measured the concentration of plasma selenium, selenoprotein P (SEPP1), and glutathione peroxidase (GPX3) activity and their interindividual differences in 383 low-income blacks and whites selected from a stratified random sample of adults aged 40-79 years, who were participating in a long-term cohort study in the southeastern United States (US). We assessed the utility of these biomarkers to determine differences in selenium status and their association with demographic, socio-economic, dietary, and other indicators.

African Americans bear a disproportionate burden of tobacco related morbidity and mortality despite smoking less than their Caucasian counterparts. Nashville's REACH 2010 initiative developed community partnerships to promote awareness, education and participatory programs to prevent and decrease smoking among residents of the northern geographic area of Nashville, TN, a majority African American community. A social-ecological model provided the framework for interventions used during a 5 year period that included: (a) community level strategies to increase awareness and knowledge about the effects of smoking; (b) individual level strategies to enlist and train community members to become advocates, lead smoking cessation classes and encourage current smokers in quit attempts; and (c) strategies directed to changing policy through education and partnership building.

Introduction: The objective of our study was to assess the psychometric properties of the Medical Outcomes Study's 12-Item Short Form Survey Instrument (SF-12) for use in a low-income African American community. The SF-12, a commonly used functional health status assessment, was developed based on responses of an ethnically homogeneous sample of whites. Our assessment addressed the appropriateness of the instrument for establishing baseline indicators for mental and physical health status as part of Nashville, Tennessee's, Racial and Ethnic Approaches to Community Health (REACH) 2010 initiative, a community-based participatory research study.

Disparities in health status persist for many sociodemographic groups in the United States. An understanding of barriers to healthcare access and utilization can assist community-based initiatives in developing strategies to improve the health of minority and low-income populations. Using self-reported information from 3014 community residents, a factor analysis was conducted that defined barriers to healthcare by 4 dimensions: (1) time and competing priorities, (2) convenience and availability, (3) healthcare utilization, and (4) healthcare affordability.
