Resumen

Most studies of altitude illness in premenopausal women traveling to high mountain environments have not controlled for phase of the menstrual cycle. Consequently, little information exists about the possible effects of cyclic fluctuations in ovarian steroid hormones on the occurrence of acute mountain sickness (AMS). We determined the incidence of AMS in 12 women volunteers during a 36 h exposure to 446 torr (∼4300 m.) in a hypobaric chamber during the early follicular (EF) and luteal (L) phases of their menstrual cycle using a cross-over study design. Additionally, we determined the incidence of AMS in 16 additional women volunteers during a 12 d residence at 4300 m on the summit of Pikes Peak, Colorado in EF (8 individuals) or L (8 individuals) using a group comparison study design. Preliminary results of these studies suggest that the incidence of AMS in women does not differ greatly between menstrual cycle phases.
