LOGAN: Psychobehavioral Factors, Arterial Stiffness, and Blood Pressure in Korean Americans (Under the direction of Debra J. Barksdale) High levels of psychological stress and a high prevalence of hypertension (HTN) have been reported in Korean Americans (KAs). Immigration may be one source of stress which contributes to HTN in KAs. Arterial stiffness is another cardiovascular condition which is also related to both stress and hypertension. Traditionally, arterial stiffness was viewed as the result of HTN, but longitudinal studies have shown that arterial stiffness may itself predict progression of HTN in non-hypertensive people. Thus, this study explored the associations among stressors (acculturation and time in the U.S.), psychobehavioral responses (psychological stress, chronic active coping, and stress emotions of anger, anxiety, and depression), and physiological responses (blood pressure and arterial stiffness) in KAs. In this study, a convenient sample of 102 KAs (aged 21-60 years, 60% women) was recruited. Subjects were asked to complete the seven psychobehavioral scales and a demographic questionnaire.
