To better understand the dynamic interrelationships of psychosocial and behavioral risk factors of the adult life span, the trajectories of hostility, depression, smoking, body mass, exercise patterns, and alcohol consumption will be mapped using multiple assessments from age 19 to age 60. It is predicted that a significant proportion of the change in risk behavior will be due to trajectories of hostility and depression, operating singly and in combination over time. Tests will be made of the prospective associations of hostility, depression, and other psychosocial variables (e.g., social support and job strain) with coronary events and mortality observed while the cohort is middle-aged. The scope of the psychosocial variables will be broadened to examine individual differences in personality over the life course and dietary practices at midlife in addition to the indicators noted above. The effect of gender on the natural history of coronary disease and coronary risk profiles in women will be examined by monitoring changes in menopausal status, and patterns of hormone replacement therapy use among women during midlife and the associations of these factors with the other risk indicators.
