Abstract Baseline and stress induced salivary cortisol levels were investigated in 63 army recruits at the beginning and the end of six week boot camp training. At the beginning of the training, the recruits were randomly distributed to nine groups, and weekly measurements of the social hierarchy within each group were obtained. Independent of the social position, baseline levels increased over the first weeks of the training period. Under experimental psychological stress, salivary cortisol levels highly increased in socially dominant subjects (14.0 nmol/l), while only a modest elevation was observed in subordinate men (2.9 nmol/l). Similar differences in response patterns were observed under physical stress. At the end of the training, blunted cortisol responses were observed to both psychological and physical stress. The data suggest a close relationship between social status and pituitary-adrenal responsiveness to psychological stress in men.
