A thorough and current literature review is presented in which the authors identify the current state of knowledge and needs for additional research. They make a clear and convincing case of the importance of the research for preventing cardiovascular mortality and morbidity in at-risk/vulnerable populations, of which their sample includes a subset (African American women residing in the rural southeastern U.S.). This research topic and the study population match well with current national research funding priorities focusing on health disparities in vulnerable populations (in this case, disparities among African American versus white women in the burden of mortality and morbidity from cardiovascular disease). There are two limitations of the study background that if addressed could have enhanced the clarity of the presentation.
