Depression, anxiety, hostility, and physical health

This study assessed the relationship of depression, anxiety, and hostility to physical health in a multicultural student population (N=106). When controlling for a variety of demographic and health risk factors (viz., age, sex, body mass, smoking, alcohol, salt, caffeine, and exercise), hostility, depression, and anxiety were related to higher reported incidences of physical symptoms and somatic illness. Depression and hostility had the strongest relationships with physical health, although the most striking single relationship was between depression and illness. Results suggest that it may be premature to focus our attention on hostility in research on the personality-illness relationship. They also suggest that the health behavior model of the relationship between personality and disease does not provide an adequate explanation, since negative affect was significantly associated with illness even when controlling for a variety of health risk factors. This work was supported, in part, by an intramural grant from the University of Hawaii, #R511.
