Our aim was to investigate plasma levels of adiponectin, monocyte chemoattractant protein-1 (MCP-1) and plasminogen activator inhibitor-1 (PAI-1) in low birth weight (LBW) children and to determine correlations among these adipokines and birth weight and cardiovascular disease risk factors. In a case-control study, the concentrations of adiponectin, MCP-1 and PAI-1 were measured in 180 schoolchildren (ages 6-11 years). MCP-1 and PAI-1 levels were significantly elevated in LBW children. Conversely, adiponectin concentration was significantly reduced in these children. Similar findings were observed after adjustment for current age, gender and abdominal circumference. Because the children with LBW had altered adipokine levels, as well as higher abdominal circumference, HOMA-IR and systolic blood pressure (SBP), we evaluated the correlation among these variables. These analyses showed that adiponectin levels were inversely correlated with systolic blood pressure (SBP) (r = -0.501; P < 0.001), HOMA-IR (r = -0.293; P = 0.023) and waist circumference (r = -0.317; P = 0.014). The proinflammatory markers were positively correlated with HOMA-IR (PAI-1: r = 0.358; P = 0.005) and waist circumference (PAI-1: r = 0.571; P < 0.001 and MCP-1: r = 0.267; P = 0.039).
Adipokines levels were correlated with cardiovascular risk factors in LBW children, and these compounds could be involved in the mechanism that links birth weight to the development of cardiovascular diseases in adulthood.
研究低出生体重(LBW)儿童的血浆脂联素、单核细胞趋化蛋白-1(MCP-1)和纤溶酶原激活物抑制剂-1(PAI-1)水平,并确定这些脂肪因子与出生体重和心血管疾病危险因素之间的相关性。
采用病例对照研究,检测了 180 名 6-11 岁学龄儿童的脂联素、MCP-1 和 PAI-1 浓度。
LBW 儿童的 MCP-1 和 PAI-1 水平显著升高,而脂联素浓度显著降低。在调整了当前年龄、性别和腰围后,仍观察到类似的结果。由于 LBW 儿童的脂肪因子水平发生了改变,同时伴有较高的腰围、HOMA-IR 和收缩压(SBP),我们评估了这些变量之间的相关性。分析表明,脂联素水平与收缩压(SBP)呈负相关(r=-0.501;P<0.001),与 HOMA-IR(r=-0.293;P=0.023)和腰围(r=-0.317;P=0.014)呈负相关。促炎标志物与 HOMA-IR 呈正相关(PAI-1:r=0.358;P=0.005),与腰围呈正相关(PAI-1:r=0.571;P<0.001,MCP-1:r=0.267;P=0.039)。
LBW 儿童的脂肪因子水平与心血管危险因素相关,这些化合物可能参与了将出生体重与成年期心血管疾病发展联系起来的机制。
