Peculiarities of the menstrual function of adolescent girls, internal migrants from the highland regions of Kyrgyzstan

Abstract

Objective: To study the nature of changes and peculiarities of the menstrual function in adolescent girls, internal migrants from the highland regions of the republic, depending on the length of stay in lowland areas. Methods: Overall 387 migrants from high-altitude girls were examined. The obtained data were compared with those of 280 girls, permanent residents of Bishkek. We examined the residence duration in both highlands and lowlands, the age of the menarche, the length of the menstrual cycle, the number of menstruation days, the frequency and the amount of blood loss before and after moving to lowland conditions. Results: Lengthening of the menstrual cycle and an increase in menstruation days, as well as, a slight increase for blood loss during menstruation were revealed. The change in place of residence also affects the regularity of the menstrual cycle, which may be due to some hypocoagulation state of the hemostasis system in them during de-adaptation to low-mountain conditions. These changes are particularly pronounced when the term of residence in the lowlands is up to 1 year. Conclusion: Thus, the study of peculiarities of menstrual function and tendencies of its changes in response to the move from highland region to the lowland region for adolescent girls showed that there is a slight increase of a menstrual cycle and an increase in the menstruation itself. In addition, there was an increase in the amount of blood loss during menstruation. The change of place of residence influenced the regularity of the menstrual cycle as well, which may be due to some hypocoagulation state of the hemostasis system in them during de-adaptation to low-mountain conditions. These changes are especially expressed for girls who just move in to the lowland region and being there for up to a year.
