Unraveling the Link Between Sedentary Behavior and Metabolic Syndrome in Women Through Insulin Resistance

Metabolic syndrome (MetS) is a prevalent clinical and public health challenge among women globally, significantly elevating the risk of cardiovascular disease and type 2 diabetes. While current clinical guidelines emphasize pharmacological interventions and general exercise recommendations, they often fail to adequately address the specific contribution of prolonged sedentary time as a modifiable risk factor, especially among high-risk women. Clarifying the biological pathway from sedentariness to MetS can inform more effective behavioral interventions in clinical and public health practice. This study delineates a coherent pathophysiology linking sedentary behavior to Metabolic syndrome in women, mediated through lipid dysregulation, chronic inflammation, and subsequent insulin resistance. The synthesis demonstrates that women undergoing perimenopause, pregnancy, or with polycystic ovary syndrome (PCOS) exhibit heightened susceptibility to sedentariness-induced metabolic dysregulation. Each of these states magnifies the impact of sedentary behavior, resulting in more severe metabolic abnormalities. The evidence underscores the value of sex-specific preventive health recommendations. Key limitations include reliance on mechanistic insights from preclinical studies and variability in objective measures of sedentary patterns across human studies. This review aims to synthesize evidence on the biological mechanisms through which sedentary behavior contributes to Metabolic syndrome in women, and to explore the modifying effect of female-specific physiological conditions, thereby providing a mechanistic basis for tailored clinical and public health interventions.
