Abstract
OBJECTIVE: To describe and compare the incidence of acute mountain sickness (AMS): a) between the genders; b) between women who are using hormonal types of contraception as contrasted with those who are not; and c) to compare the incidence of AMS between stages of the female menstrual cycle. DESIGN: Descriptive correlational survey. SETTING: Camp Muir, elevation 3,072 meters, on Mt. Rainier (4,392 m) in Washington State, during the summer climbing season, June through August 1995. PARTICIPANTS: 44 recreational climbers (35 men and 9 women) between the ages of 18 through 52, who had attempted the summit of Mt. Rainier. MAIN OUTCOME MEASURES: Participants completed the Lake Louise Consensus Questionnaire and a demograpllic questionnaire, plus underwent a brief physical exam, to quantify the occurrence of acute mountain sickness. In addition, women answered several questions regarding the use of hormonal contraceptives, and timing of menstrual cycles. An attempt to correlate menstrual cycle phases to AMS susceptibility was also made. RESULTS: Although this study attempted to investigate if hormonal contraceptive use or the menstrual cycle stage is correlated with AMS incidence, the results did not support any difference between genders and the incidence of AMS, given the sample size of nine women. Neither was the use of hormonal contraception nor the menstrual cycle stage associated with increased or decreased AMS rates. Further elucidation of the effects of either endogenous or exogenous progesterone on AMS was not obtained. CONCLUSIONS: A more adequate sample size of women is needed to determine accurately whether hormonal contraception affects AMS incidence. Investigation is needed to determine the accuracy of the method used in this study to extrapolate menstrual cycle phases. Additional research controlling for menstrual cycle phases, plus the type of hormonal contraception and the effect of progesterone on AMS, is also suggested.
