Hubungan Indeks Massa Tubuh dengan Siklus Menstruasi pada Remaja Putri Kelas VIII di SMP Negeri 28 Medan

Abstract

Background. During adolescence, a woman will experience a change in physiological condition, called menstruation. Menstruation is the process of discharge from the mucous membrane of a woman's uterine wall which contains many blood vessels, and generally occurs 3 to 7 days a month. Body mass index is one of the parameters to place a person into the categories of underweight, normal, overweight and obese. The interpretation of these characteristics is used as risk factors for the prevalence of health problems. A high or low body mass index can cause menstrual cycle disorders in the form of amenorrhea, menstrual irregularities and pain during menstruation. This is because fat is a substance that can influence the process of forming the hormone estrogen, so it greatly influences the condition of the body and the hormone production system which is closely related to menstruation. However, the lack of research regarding the correlation between the two can cause bias for clinicians in determining the correct diagnosis for patients. Objectives.
