In a cross-sectional study involving 965 participants, researchers explored the relationship between obesity and arterial stiffness, a predictor of cardiovascular diseases. They hypothesized that inflammatory markers could mediate this connection. Obesity, defined as having a BMI of 30 or higher, was associated with higher carotid-femoral pulse wave velocity (PWV), indicating increased arterial stiffness. Even after adjusting for confounding variables, the association between PWV and obesity persisted. Obesity was also linked to elevated levels of various inflammatory markers. Mediation analysis suggested that inflammatory burden partially mediated the association between PWV and obesity, with leptin and insulin resistance potentially playing contributing roles. These findings underscore the role of inflammation in obesity-related arterial stiffness, with leptin and insulin resistance potentially exacerbating the condition.
