Hormone therapy can significantly reduce insulin resistance, shows new meta-analysis

Cumulative totals of the 17 different trials included 15,350 participants who were randomized to hormone therapy including estrogen alone or estrogen plus progestogen and 13,937 who were randomized to placebo. The mean age of the study population ranged from 47 to 75 years, and treatment duration ranged from eight weeks to two years.

“Our analysis showed that both types of hormone therapy, including oral and transdermal routes, significantly reduced insulin resistance in healthy postmenopausal women, although estrogen alone was associated with a more prominent reduction when compared to a combination hormone therapy,” says Dr. Xuezhi (Daniel) Jiang, lead researcher from Reading Hospital Tower Health and Drexel University College of Medicine in Pennsylvania.

More detailed results will be discussed at the 2024 Annual Meeting of The Menopause Society as part of the oral abstract presentation titled “Effect of hormone therapy on insulin resistance in healthy postmenopausal women: A systematic review and meta-analysis of randomized placebo-controlled trials.”

“Hormone therapy is an effective treatment for many bothersome menopause symptoms, including hot flashes,” says Dr. Stephanie Faubion, medical director for The Menopause Society. “This new metaanalysis is important as declining estrogen levels in menopausal women put them at greater risk for insulin resistance and hormone therapy could be beneficial in reducing insulin resistance in these women.”
