title: Junior doctors and the full shift rota--psychological and hormonal changes: a comparative cross-sectional study.
abstract: We studied the hormonal and psychological effect of the full shift rota on junior doctors after implementation of the European Working Time Directive, using a comparative, cross-sectional study design of male doctors in South Yorkshire. Cortisol and testosterone levels were measured and subjects completed the general health questionnaire (GHQ-12) and the androgen deficiency in the aging male screening questionnaire (ADAM), after a week of holiday (baseline), a week of nights, and a normal working week. The results showed that cortisol levels decreased from 480.6 +/- 33.1 nmol/l at baseline (after a week of holiday), to 355.7 +/- 29.1 nmol/l post normal working week (p = 0.003); to 396.7 +/- 32.5 nmol/l post nights (p = 0.03). GHQ-12 scores increased from 0.5 +/- 0.3 at baseline, to 1.8 +/- 0.5 post normal working week (p = 0.02) and to 2.3 +/- 0.5 post nights (p = 0.005). These results suggest that there are still appreciable physiological consequences with new work patterns.
