title: [Diurnal blood pressure rhythms in night shift workers in terms of age and work experience: issues of adaptation].
abstract: The circadian rhythms of blood pressure (BP) are studied in working persons within every hour of day and night by the means of multipoint measurements of BP in pre-shift period. The analysed cohort consists of 34 163 locomotive drivers (544 804 individual BP measurement points). Basing on these data the average diurnal BP profiles (DPBP) are plotted for different age and work experience groups. It is established that all DPBPs are of non-dipper type. This can be considered as a mechanism of adaptation being a compromise between work requirements and minimization of health hazard. This kind of adaptation develops approximately in one year period.
