Plasma Taurine in Older Women With Obesity: Impact of Metabolic Phenotype and Combined Exercise

Sponsor: University of Sao Paulo

Summary

Population aging has been accompanied by a rise in obesity and other chronic diseases, increasing cardiovascular risk particularly among women, who exhibit a higher prevalence in older age groups compared to men. Aging and obesity share pathophysiological mechanisms, such as chronic inflammation and oxidative stress. However, distinct obesity phenotypes exist, such as metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUO). Consequently, therapeutic interventions involving nutritional strategies and physical training are highly relevant, especially for older women. Taurine, a sulfur-containing amino acid, plays a role in modulating oxidative stress, inflammation, osmoregulation, and mitochondrial function. Rationale: Plasma taurine concentrations are lower in women with obesity compared to healthy individuals. However, studies investigating these concentrations across different phenotypes-particularly in older women, a group susceptible to functional and metabolic changes-remain limited. Understanding these variations could clarify taurine's role in the pathophysiology of obesity and aging and inform personalized therapeutic strategies. Combined physical training stands out as an effective strategy for modulating inflammatory, oxidative, and metabolic pathways, in addition to improving psychosocial aspects. Given that taurine levels can be influenced by these pathways, investigating the taurine response to physical training across different metabolic phenotypes may contribute to developing low-cost interventions aimed at improving the quality of life for older women with obesity.
