    Postmenopausal women experience high rates of sleep-disordered breathing. Medroxyprogesterone (MPG) showed a potential to reduce apnea duration, but further research is needed.

    Area of Science:

    • Sleep Medicine
    • Endocrinology

    Background:

    • Postmenopausal women exhibit a higher incidence of sleep-disordered breathing and nocturnal oxygen desaturation compared to premenopausal women.
    • Progestational hormones are hypothesized to play a role in the occurrence of these sleep events.

    Purpose of the Study:

    • To evaluate the contribution of progestational hormones, specifically medroxyprogesterone (MPG), to sleep-disordered breathing and nocturnal oxygen desaturation in postmenopausal women.

    Main Methods:

    • A randomized, double-blind, placebo-controlled study involving 21 postmenopausal women.
    • Subjects received either 30 mg of medroxyprogesterone (MPG) or placebo daily for approximately one month.
    • Respiration, oxygen saturation, and electroencephalography were monitored during one night of sleep before and after therapy.

    Main Results:

    • 71% of postmenopausal women experienced sleep-disordered breathing and desaturation events.
    • The placebo group showed no significant changes in sleep or breathing variables.
    • Medroxyprogesterone (MPG) treatment resulted in a statistically significant reduction in the maximum duration of apnea (p < 0.03).

    Conclusions:

    • Sleep-disordered breathing and nocturnal oxygen desaturation are prevalent in postmenopausal women.
    • Medroxyprogesterone (MPG) may offer a therapeutic benefit by reducing apnea duration in this population.
    • Further investigation is warranted to fully elucidate the role of progestational hormones in sleep disorders.
