    Area of Science:

    • Gerontology
    • Pharmacology
    • Women's Health

    Background:

    • Postmenopausal hormone therapy is widely used.
    • Understanding estrogen use patterns in older populations is crucial for health management.

    Purpose of the Study:

    • To investigate the prevalence and patterns of oral and vaginal estrogen use among postmenopausal women in a retirement community.
    • To identify the most commonly used estrogen preparations and their duration of use.

    Main Methods:

    • Retrospective analysis of medication use in a retirement community population.
    • Data collection on oral and vaginal estrogen preparations, age, and duration of use.

    Main Results:

    • 15% of postmenopausal women used oral estrogens, with continued use and new-initiation observed in their 70s, 80s, and 90s.
    • Oral estrogen use and age-specific prevalence declined after age 70.
    • Mean duration of continuous oral estrogen use was 105 months.
    • Vaginal estrogen use was infrequent, brief, and often concurrent with oral estrogen use.
    • Conjugated equine estrogens (Premarin) were the most frequently used oral preparation.

    Conclusions:

    • Oral estrogen therapy remains prevalent in older postmenopausal women, indicating ongoing therapeutic use beyond traditional age cutoffs.
    • While overall use declines with advanced age, initiation and sustained use persist, highlighting the need for continued monitoring and individualized treatment strategies.
    • Conjugated equine estrogens are the predominant oral estrogen formulation utilized in this demographic.
