[Prevalence of menorrhagia among women in Reunion Island]

To estimate the prevalence of menorrhagia in women in Reunion Island using the Higham score, to evaluate self-reporting as an alternative diagnostic method, and to study women's level of knowledge about menorrhagia and its impact on their quality of life.

This was a descriptive, cross-sectional observational study involving 185 adult women with menstrual periods living in Reunion Island. Women volunteered to answer an online self-questionnaire proposed by healthcare professionals from January to May 2023 in Reunion Island. They completed a general information questionnaire, the Higham score, a menorrhagia knowledge questionnaire and a menstrual quality of life questionnaire.

The prevalence of menorrhagia in the sample was 48.1% using the Higham score and 46.5% using self-report. Women's level of knowledge about menorrhagia is still insufficient, given the significant impact on quality of life during menstruation among those suffering from this symptom.

The prevalence of menorrhagia in our sample of women on Reunion Island is high. Measures need to be taken to break the taboos surrounding menstruation, promote menstrual education and foster a better understanding by women of menstrual pathologies, particularly menorrhagia. Early detection of this symptom would enable faster treatment and avoid complications and adverse effects on quality of life.
