ObjectivesThe John Henryism (JH) hypothesis suggests that, under adverse social and economic conditions, high-effort coping styles that reflect hard work and determination may contribute to elevated blood pressure. Results from tests of this hypothesis have been mixed, with variations by region, urban versus rural areas, race, gender, and age. The majority of studies reporting that socioeconomic position modifies associations between JH and blood pressure have been for non-Latino Blacks in rural communities. In contrast, most studies conducted in urban areas report little support for the JH hypothesis. Few studies have been conducted in samples that include Latinos. We extend previous research by testing the JH hypothesis in a multi-ethnic, low-to-moderate income urban community.
