English abstract
The objectives of this study were to determine the prevalence of dysmenorrhoea in Omani
high schoolgirls, its impact and the treatment used. Methods: A cross-sectional survey was carried out in May
2010 on 404 girls from two public high schools in the Muscat region. Data were collected by self-administered
questionnaire including information on demographics, prevalence of dysmenorrhoea, severity, its impact, and the
treatment used. Results: Overall, 94% (n = 380) of the participants had dysmenorrhoea. It was mild in 27% (n = 104),
moderate in 41% (n = 155), and severe in 32% (n = 121). Dysmenorrhoea was the cause of limited sports activities
in 81%, decreased class concentration in 75%, restricted homework in 59%, school absenteeism in 45%, limited
social activities in 25%, and decreased academic performance in 8% of the affected students. Only 3% (n = 10) had
consulted a physician; 21% (n = 80) self-medicated, and 55% (n = 210) took no action. The commonest drugs used
were paracetamol (n = 60, 16%), ibuprofen (n = 29, 8%) and mefenemic acid (n = 12, 3%). There was no statistically
significant correlation between dysmenorrhoea, demographics and menstrual characteristics. Conclusion: Dysmenorrhoea is a prevalent and yet undertreated menstrual disorder among Omani adolescent schoolgirls. The
pain suffered can be severe and disabling. Doctors should therefore be prepared to discuss this more freely with
schoolgirls. In addition, there is a need for education regarding dysmenorrhoea and treatment options to minimise
the impact on school, sports, social and daily activities.
