OBJECTIVES: Menorrhagia affects up to 30% of women and has a profound clinical and societal impact, affecting sexual activity, relationships, confidence, mood, employment, physical health and overall wellbeing. However, a representative and contemporary estimate of its prevalence and incidence does not exist. Given its widespread and significant impacts, menorrhagia is a public health concern. This paper aims to provide an accurate and representative estimate of menorrhagia incidence and prevalence in the UK to inform targeted interventions.
METHODS: The aim of this population-based retrospective cohort study was to calculate the crude incidence rate and crude point prevalence of menorrhagia (in those under 60 years old) from 01-01-2006 to 31-12-2021 using de-identified electronic health records from THIN (UK primary care dataset extracted using Dexter).
RESULTS: The incidence rate generally declined from 2006 and reached 729.46 per 100,000 person-years in 2019. Following the Covid-19 pandemic it declined significantly and reached 490.03 per 100,000 person-years in 2021. Prevalence has been generally increasing since 2006 to 9923.26 per 100,000 females in 2021. The highest incidence rate in 2021 was in the black population, reaching 754.23 per 100,000 person-years. The age group with the highest prevalence in 2021 was 41-50 year-old patients at 15851.47 per 100,000 people.
CONCLUSIONS: The Incidence rate has been declining, and prevalence has been slow to rise in recent years. It is unlikely that less women are living with this condition and more likely that more need to be done to diagnose and treat the symptoms of menorrhagia, especially following the pandemic. The high prevalence in the 41-50 years old subgroup is clinically relevant and may mean that this age group would benefit from targeted interventions.
