Insights
Hypertension significantly increases healthcare costs for women using menopausal hormone therapy (HT). The annual burden of illness for hypertension in this group is substantial, averaging $2948 per person.
Area of Science:
- Reproductive Medicine
- Cardiovascular Health
- Health Economics
Background:
- Menopausal hormone therapy (HT) is commonly used by women.
- Hypertension is a prevalent comorbidity in the general population.
- Understanding the health economic impact of comorbidities in HT users is crucial.
Purpose of the Study:
- To estimate the burden of illness (BOI) associated with hypertension in women undergoing menopausal hormone therapy (HT).
- To quantify the difference in healthcare expenditures between hypertensive and non-hypertensive HT users.
Main Methods:
- Retrospective cohort study using the PharMetrics database (July 2003 - June 2005).
- Inclusion of patients with at least one menopausal HT prescription.
- Propensity score matching to compare hypertensive and non-hypertensive HT cohorts based on demographics, comorbidities, and HT type.
Main Results:
- Hypertension was the most frequent comorbidity (34%) in the menopausal HT cohort.
- Hypertensive HT users (n=106,729) incurred significantly higher annual healthcare costs ($8908) than non-hypertensive users ($5960).
- The average annual BOI of hypertension was $2948 per person (p < 0.001).
Conclusions:
- Hypertension is the leading comorbidity among menopausal HT users in the US.
- The economic burden of hypertension in this population is substantial and statistically significant.
- Findings highlight the importance of managing hypertension in women using menopausal hormone therapy.
Objective:
To estimate the burden of illness (BOI) of hypertension in a cohort of women receiving menopausal hormone therapy (HT).
Methods:
Patients with at least one prescription for menopausal HT were selected from the PharMetrics database during the period July 1, 2003, to June 30, 2005. Hormone therapy patients were divided into those with and without hypertension. The nonhypertensive cohort was propensity score-matched to the hypertensive cohort, controlling for patient demographics, overall comorbidities, and type of HT use. The BOI of hypertension in the menopausal HT cohort was defined as the difference in average annual total healthcare expenditures per person between the cohorts.
Results:
The prevalence of menopausal HT use was 9.75% among potentially eligible patients in this commercially insured sample. Hypertension was the most common comorbidity in the menopausal HT cohort, with a prevalence of 34%. Hormone therapy patients with hypertension (n = 106,729) had significantly higher average annual healthcare expenditures compared to matched HT patients without hypertension ($8908 vs. $5960 per person per year; difference of $2948; p < 0.001).
Conclusions:
Hypertension is the most common comorbidity among menopausal HT users in the United States. The annual BOI of hypertension is both substantial and significant when compared to matched patients without hypertension, averaging $2948 per patient per year.

Hormonal Regulation of Blood Pressure
Epinephrine and Norepinephrine
The adrenal medulla releases epinephrine and norepinephrine, catecholamines that enhance and extend the sympathetic or "fight or flight" physiological response. These hormones escalate heart rate and the force of contraction while...
Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.
