In women, leptin correlates with weight (rho = 0.496, p = 0.001), BMI (rho = 0.577, p < 0.001), abdominal circumference (rho = 0.505, p < 0.001), diabetes (rho = 0.408, p = 0.006) and ponderal status (rho = 0.537, p < 0.001) ghrelin with age (rho = −0.434, p = 0.003), weight (rho = 0.304 p = 0.004), and the leptin/ghrelin ratio with age (r = 0.363, p = 0.015), BMI (r = 0.387, p = 0.009), abdominal circumference (r = 0.338, p = 0.018), diabetes (r = 0.477, p = 0.001), and ponderal status (r = 0.359, p = 0.017). Here, GHRL is linked to diabetes mellitus.
