Title: | Body mass index, body fat mass and the occurrence of amenorrhea in ballet dancers | Authors: | Edita Stokić Biljana Srdić Galić Otto Barak |
Keywords: | body fat;amenorrhea;balet dancers;bioelectrical impendance;body mass index | Issue Date: | 2005 | Journal: | Gynecological Endocrinology | Abstract: | To evaluate the connection between menstrual disorders and body fat mass, we examined a group of 30 ballet dancers and a group of 30 non-athletic girls (controls). Body mass index (BMI) was calculated and percent body fat (FAT%) was measured using the bioelectrical impedance method. A questionnaire was used to obtain age at menarche and duration of menstrual cycles. Ballet dancers had significantly lower values of BMI (18.56 ± 1.53 vs. 19.96 ± 2.12 kg/m2) and FAT% (18.85 ± 4.50 vs. 23.41 ± 4.34%) compared with controls. According to BMI, 50.0% of ballet dancers and 23.3% of the control group were underweight. Of underweight ballet dancers, 66.7% had lower values of body fat, while most underweight girls from the control group had normal body fat. Normal-weight obesity was registered in 40.9% of the control group and in 6.7% of ballet dancers. Amenorrhea was found in 20.0% and oligomenorrhea in 10.0% of ballet dancers. Ballet dancers more frequently had later appearance of menarche and menstrual cycles of longer duration than did non-athletic girls. A significant negative correlation was found between menstrual cycle duration and FAT% among ballet dancers (r =–0.415). To prevent complications caused by changes of body fat mass, we conclude that body composition assessment in ballet dancers is very important. | URI: | https://open.uns.ac.rs/handle/123456789/32505 | ISSN: | 0951-3590 | DOI: | 10.1080/09513590400027224 |
