The study examined changes in and relationship between body mass index (BMI), leptin and adiponectin levels over a 3-year period in a pediatric population-based cohort.
A 3-year prospective cohort study of 268 boys and 251 girls aged 9-10 in Ina, Saitama, Japan.
Median body mass index (BMI) significantly increased from baseline (age 9-10) to follow up (age 12-13) in boys from 17.1 to 18.3 kg/m2 (P < 0.001) and in girls from 16.5 to 18.5 kg/m2 (P < 0.001), respectively. Adiponectin values significantly decreased from baseline to follow up in boys (13.5 to 8.9 microg/ml, respectively) (P < 0.001) and in girls (12.4 to 9.5 microg/ml, respectively) (P < 0.001). Leptin values at follow up significantly decreased from baseline in boys (4.9 to 2.3 ng/dl, respectively) (P < 0.001) and also in girls (5.3 to 5.1 ng/dl, respectively) (P = 0.049). A relatively strong correlation was seen in BMI (Spearman's correlation coefficient, r = 0.864, P < 0.001 in boys; r = 0.873, P < 0.001 in girls), adiponectin (r = 0.705, P < 0.001 in boys; r = 0.695, P < 0.001 in girls), and leptin (r = 0.449, P < 0.001 in boys; r = 0.610, P < 0.001 in girls) before and after the three-year period. The ratio of follow up to baseline BMI was negatively correlated with that for adiponectin (r = -0.224, P < 0.001 in boys; r = -0.165, P = 0.001 in girls) and positively correlated with that for leptin (r = 0.518, P < 0.001 in boys; r = 0.609, P < 0.001 in girls).
This study demonstrated that baseline adiponectin, leptin and BMI values measured at ages 9-10 correlated with those measured three years later. However, adiponectin values decreased and leptin values increased in those subjects whose BMI increased during over this period.
本研究调查了一个基于人群的儿科队列中,三年间体重指数(BMI)、瘦素和脂联素水平的变化及其相互关系。
对日本埼玉县伊奈市268名9 - 10岁男孩和251名9 - 10岁女孩进行为期三年的前瞻性队列研究。
男孩的体重指数中位数从基线(9 - 10岁)到随访(12 - 13岁)显著增加,从17.1增至18.3kg/m²(P < 0.001),女孩从16.5增至18.5kg/m²(P < 0.001)。脂联素值在男孩中从基线到随访显著降低(分别为13.5至8.9μg/ml)(P < 0.001),在女孩中也显著降低(分别为12.4至9.5μg/ml)(P < 0.001)。随访时男孩的瘦素值从基线显著降低(分别为4.9至2.3ng/dl)(P < 0.001),女孩也显著降低(分别为5.3至5.1ng/dl)(P = 0.049)。在三年前后,BMI(男孩的斯皮尔曼相关系数r = 0.864,P < 0.001;女孩的r = 0.873,P < 0.001)、脂联素(男孩的r = 0.705,P < 0.001;女孩的r = 0.695,P < 0.001)和瘦素(男孩的r = 0.449,P < 0.001;女孩的r = 0.610,P < 0.001)之间存在较强的相关性。随访与基线BMI的比值与脂联素的比值呈负相关(男孩的r = -0.224,P < 0.001;女孩的r = -0.165,P = 0.001),与瘦素的比值呈正相关(男孩的r = 0.518,P < 0.001;女孩的r = 0.609,P < 0.001)。
本研究表明,9 - 10岁时测量的基线脂联素、瘦素和BMI值与三年后测量的值相关。然而,在此期间BMI增加的受试者中,脂联素值降低,瘦素值增加。
