Menstrual Health in Servicewomen: The Menstrual Cycle, Menstrual Disturbances, and Occupational Consequences.

BACKGROUND: Most women serving in the military do so during their reproductive life and enter service at a young gynecological age. This review provides an overview of the menstrual cycle and summarizes the evidence for menstrual cycle disturbances in the military and how these disturbances to the menstrual cycle impact health and performance in the military. MAIN TEXT: Servicewomen often manage the practical challenges of menstruation and symptoms of the menstrual cycle or menstrual disturbances/dysfunction in an austere environment with no formalized support and/or education, and with unknown stigma and risks. Menstrual health in the military context implies that those who experience a menstrual cycle can access timely information, diagnosis, and support/treatment to achieve "a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity, in relation to the menstrual cycle." Herein we describe how menstrual health is impacted in a multistressor environment, including nutrition (energy balance and energy availability, micronutrients, and microbiome), physical activity, and recovery (occupational tasks, sleep, psychological stress, environment), and how menstrual disturbances can affect occupational performance and the lived experience of the female workforce. CONCLUSIONS: We call for action of militaries worldwide to protect the health of Servicewomen to maximize their potential. Low representation, relatively recent full integration of women into the military workforce, and the exclusion of women from military research have led to policies developed from evidence on men, with the potential to impact the health and performance of Servicewomen.
