Racial Differences In The Impact Of A Worksite Wellness Program On Cardiovascular Biomarkers, Ceabert Joseph Griffith
Walden Dissertations and Doctoral Studies
Cardiovascular disease (CVD) is responsible for approximately 600,000 deaths in the United States each year, with African Americans (AAs) disproportionately affected. Individual-level approaches to reducing CVD remain ineffective, mobilizing a movement that advocates for population-based solutions. Workplace wellness programs (WWPs) have gained considerable traction as a viable strategy for ameliorating CVD burden among workers in general. However, no studies have looked at the efficacy of WWPs in ameliorating CVD specifically among AA employees--a knowledge gap that this investigation aimed to close. Based on the health belief model and the social cognitive theory, this retrospective cohort study used de-identified secondary data …
