Objective: To quantify prescribing of hormone replacement therapy (HRT) in women aged 40-60 years by type of HRT and length of use, and to determine sociodemographic factors associated with receiving a HRT prescription. Design: Population based cohort study. Setting: QResearch database of primary care practices in England, 1 January 2013 to 13 July 2023, and patient electronic health records for prescribing information . Participants: 1 978 348 women aged 40-60 years at any time over a 10 year period. Main outcome measures: Overall uptake of two or more prescriptions of the same type of HRT in women of menopausal age, length of use, and association between ethnic group, deprivation, and geographical region and receiving a HRT prescription before and during the eight years since implementation of National Institute for Health and Care Excellence (NICE) guidance on the menopause in 2015 in the UK. Results: The cohort comprised 1 978 348 women with a mean age of 49.4 years, and 76.2% were white women. Overall, 379 911 (19.2%) women received two or more HRT prescriptions. Combination HRT formulations in one prescription were the most frequently prescribed (62.4% of those prescribed HRT), with 43.3% receiving oral and 26.3% transdermal formulations. Mean age at first prescription was 49.8 years. Rates for two or more prescriptions of HRT were higher in white women (22.6%) than in other ethnic groups, ranging from 8.9% in Caribbean women to 3.9% in black African women. Prescription rates decreased with increasing social deprivation, from 24.2% in the most affluent to 10.9% in the most deprived groups. London had lower prescription rates (11.7%) than other regions (all >19%). Multivariable Cox regression showed that non-white ethnic groups had significantly lower HRT prescription rates (hazard ratios 0.85-0.92, P<0.001), and each increase in social deprivation group was associated with lower HRT prescription rates (hazard ratio for the most deprived group 0.92, 95% confidence interval 0.92 to 0.93, P<0.001). Conclusions: This study identified differences in HRT prescribing in England based on ethnic group, socioeconomic status, and geographical location. White women and those in more affluent neighbourhoods were more likely to receive HRT than non-white women and those in more deprived areas. These findings suggest potential inequities that require further exploration.
