Abstract

In this cross-sectional study, two high schools in Semnan county were selected through cluster sampling and a total of 386 students who had experienced their first two years post-menarche were examined to identify the presence and type of menstrual disorders, as well as factors such as age at menarche, body mass index, chronic illnesses, medication use, and family history of menstrual issues. The participants' ages ranged from 12 to 18 years. The findings revealed that menstrual disorders were quite common during the first two years after menarche, affecting 48.2% of participants. Polymenorrhea was the most frequently reported disorder at 34%, while menometrorrhagia was the least common at 5.4%. The study indicated that individuals with a body mass index below 15 or above 25 were more likely to experience menstrual disorders, suggesting a correlation between body mass index and menstrual health. Those who experienced menarche at a later age tended to have more menstrual irregularities. Additionally, a positive family history of menstrual disorders was more commonly found among sisters or mothers of individuals with amenorrhea compared to those with other menstrual issues, although no significant link was established between menstrual status and family history. Despite the high incidence of menstrual disorders, only a small percentage (5.5%) sought medical help. The results of this study are largely consistent with international research, with minor variations likely attributed to geographical factors, dietary habits, ethnicity, and other influences, as sexual maturation and related issues can differ based on these elements.
