Leptin to high-molecular-weight adiponectin ratio is independently correlated with carotid intima-media thickness in men, but not in women.

BACKGROUND: The leptin:adiponectin ratio (L:A ratio) is an independent predictor of carotid intima-media thickness (CIMT). OBJECTIVE: To evaluate whether the leptin:high-molecular-weight adiponectin ratio (L:HA ratio) is associated with CIMT in the general population. METHODS: We investigated the relationship between the L:HA ratio and CIMT in 233 Japanese study participants (106 men and 127 women). RESULTS: After adjustment for confounding factors, CIMT was significantly correlated with the log L:HA ratio (beta = 0.11, p = 0.014) in men, whereas no correlation was observed in women (beta = 0.01, p = 0.50). Conclusion: The L:HA ratio is closely correlated with CIMT in men, but not in women
