Abstract

Hostility may be related to risk factors for cardiovascular disease (CVD), such as blood pressure. However, the process by which hostility affects blood pressure is not fully understood. The current study sought to evaluate abdominal obesity (waist-to-hip ratio [WHR]) as a potential mediator and modifier of the relationship between cynical hostility and systolic blood pressure (SBP) in a group of disadvantaged women. Path analysis and multiple regression models were used to identify mediating and moderating pathways in the relationship between cynical hostility and SBP. Results indicate a significant interaction between WHR and cynical hostility. WHR was a partial mediator and significant moderator of the association between hostility and blood pressure. These findings highlight the potential importance of examining abdominal obesity and psychosocial factors as conjunctive determinants of CVD and risk factors for related metabolic conditions.
