Ratio of the values for BMI, adiponectin and leptin measured at ages 9 – 10 to those measured at 12 – 13, and their correlation by gender in the 519 children living in the town of Ina. Boys (+): n = 268, Girls (○): n = 251. r: Spearmans' correlation coefficients. Ratio: values measured at ages 12–13/values measured at ages 9–10. Straight line, medians for boys; dotted line, medians for girls. Adiponectin: r = -0.224, P < 0.001 in boys, r = -0.165, P = 0.001 in girls. Leptin: r = 0.518, P < 0.001 in boys, r = 0.609, P < 0.001 in girls.
