The Influence Of Exercise On Cardiometabolic Risk In Perimenopause: A Systematic Review, Bibha Gautam, Deborah J. Clegg, Mary Madeline Rogge, Jeni Page

International Nursing Research Congress (INRC)

Purpose: Perimenopause is a biologically vulnerable period characterized by hormonal fluctuations, visceral fat accumulation, and increasing insulin resistance, factors that elevate cardiometabolic risk and contribute to the development of cardiometabolic syndrome (CMS), defined as the presence of three or more metabolic abnormalities. These changes reflect a continuum of metabolic vulnerability that may emerge before CMS becomes clinically detectable. Although regular exercise can mitigate this risk, limited evidence clarifies which exercise modalities are most effective in reducing metabolic risk and CMS prevalence among women undergoing the perimenopausal transition. Despite facing a distinct and often underrecognized vulnerability to CMS, perimenopausal women remain …
