Abstract
OBJECTIVE: The present research aimed to study the relationship between body mass index and menstrual disorders at different ages of menarche and sex hormones. METHODS: In this cross-sectional study, 2000 girls aged between 9 and 18 in all levels were selected through cluster sampling in Shiraz. Data were collected using demographic characteristics, menstrual disorders, body mass index and hormones' measure questionnaires. To analyze the data, we used SPSS 16 and Chi-square test. RESULTS: A total of 1024 (51.2%) out of 2000 subjects had normal BMI and the smallest group belonged to 26 subjects (1.3%) with BMI ≤ 30. There is a significant relationship between body mass index, menstrual cycle length (p = 0.006), spotting (p = 0.005), passing clots (p = 0.001) and menstrual bleeding (p = 0.04), and this relationship is insignificant between body mass index and duration of bleeding (p = 0.95), amenorrhea (p = 0.03), dysmenorrhea (p = 0.26) and menstrual regularity (p = 0.95). Investigating the relationship between body mass index and some of sex hormones shows that there is no significant relationship among BMI and TSH (p = 0.94), FSH (p = 0.21), LH (p = 0.21), Prolactin (p = 0.97), Testosterone (p = 0.66), and DHEAS (p = 0.94). CONCLUSIONS: A significant relationship among BMI and menstrual cycle length, spotting, passing clots and menstrual bleeding, and was insignificant with sex hormones.
