Relationship Of Menstrual Cycle Disorder With Bone Mineral Density In Adolescent Female Athlete

Abstract

Purpose: The purpose of this study is to analyze the relationship of menstrual cycle disorder with bone mineral density in adolescent female athlete Methodology: The study was conducted on May-July 2019 at BPPLOP in Central Java Province, Salatiga Athletics Club, Athletics and Swimming Club Semarang State University. This study used cross sectional design, 70 subjects aged 13-21 years were selected by purposive sampling method. The data included height, weight, body fat percentage measured by microtoise and Bioelectrical Impedance Analyzer, menstrual cycle history and food intake obtained through questionnaire interview and Semi Quantitative Food Frequency Questionnaire, physical activity (current bone physical activity/cBPA, past bone physical activity/pBPA, total bone physical activity/tBPA) measured by Bone-specific Physical Activity Questionnaire and bone mineral density measured by Quantitative Ultrasound method. Data were analyzed by chi-square and binnary logistic regression test. Results: All of subjects had normal bone mineral density, 21.4% of subjects had menstrual cycle disorder. Menstrual cycle disorder, body fat percentage, cBPA, and nutrition intakes (energy, protein, calcium, vitamin D, magnesium, potassium, sodium) had no relation with bone mineral density, but intake phosphorus, pBPA and tBPA had relation with bone mineral density. Regression analysis showed that pBPA had the strongest influence with bone mineral density (p=0.032). Applications/Originality/Value: This study contributes to solving nutrition problem in adolescent female athlete and as a basis for intervention in the problem of female athlete triad.
