背景:出生体重(BW)与成年期心脏代谢疾病(CMD)的风险有关,这可能取决于肥胖的状态,特别是如果在年轻时发展。我们假设BW和BW的多基因评分(PGS)与儿童和青少年的心脏代谢风险和相关血浆蛋白水平相关。我们旨在确定儿童肥胖对这些关联的改善作用。
方法:我们使用了HOLBAEK横断面研究的数据,纳入了4263名参与者(中位[IQR]年龄,11.7[9.2,14.3]岁;57.1%的女孩和42.9%的男孩;48.6%来自肥胖诊所,51.4%来自基于人群的群体)。我们收集了体重和胎龄的信息,人体测量学,心脏代谢危险因素,计算BW的PGS,并使用Olink炎症和心血管II面板测量血浆蛋白。我们采用多元线性回归来检验与BW作为连续变量的相关性,并进行相互作用分析以评估儿童肥胖对心脏代谢风险和血浆蛋白水平的影响。
结果:BW和BW的PGS与儿童和青少年心脏代谢风险和血浆蛋白水平相关。儿童肥胖改变了BW与胰岛素抵抗指标之间的关联,包括HOMA-IR(肥胖的βadj[95%CI/SD]:-0.12[-0.15,-0.08];正常体重:-0.04[-0.08,0.00];Pinteraction=0.004),c-肽(肥胖:-0.11[-0.14,-0.08];正常体重:-0.02[-0.06,0.02];P相互作用=5.05E-04),和SBPSDS(肥胖:-0.12[-0.16,-0.08];正常体重:-0.06[-0.11,-0.01];P相互作用=0.0479)。儿童肥胖症还改变了BW与14种蛋白质的血浆水平之间的关联(例如,IL15RA,MCP1和XCL1;P相互作用<0.05)。
结论:我们确定了低体重和不良代谢表型之间的关联,特别是胰岛素抵抗,血压,改变了血浆蛋白水平,这在肥胖儿童中更为明显。需要为该人群制定有效的预防和治疗策略,以降低未来CMD的风险。

BACKGROUND: Birth weight (BW) is associated with risk of cardiometabolic disease (CMD) in adulthood, which may depend on the state of obesity, in particular if developed at a young age. We hypothesised that BW and a polygenic score (PGS) for BW were associated with cardiometabolic risk and related plasma protein levels in children and adolescents. We aimed to determine the modifying effect of childhood obesity on these associations.
METHODS: We used data from The cross-sectional HOLBAEK Study with 4263 participants (median [IQR] age, 11.7 [9.2, 14.3] years; 57.1% girls and 42.9% boys; 48.6% from an obesity clinic and 51.4% from a population-based group). We gathered information on BW and gestational age, anthropometrics, cardiometabolic risk factors, calculated a PGS for BW, and measured plasma proteins using Olink Inflammation and Cardiovascular II panels. We employed multiple linear regression to examine the associations with BW as a continuous variable and performed interaction analyses to assess the effect of childhood obesity on cardiometabolic risk and plasma protein levels.
RESULTS: BW and a PGS for BW associated with cardiometabolic risk and plasma protein levels in childhood and adolescence. Childhood obesity modified the associations between BW and measures of insulin resistance, including HOMA-IR (βadj [95% CI per SD] for obesity: -0.12 [-0.15, -0.08]; normal weight: -0.04 [-0.08, 0.00]; Pinteraction = 0.004), c-peptide (obesity: -0.11 [-0.14, -0.08]; normal weight: -0.02 [-0.06, 0.02]; Pinteraction = 5.05E-04), and SBP SDS (obesity: -0.12 [-0.16, -0.08]; normal weight: -0.06 [-0.11, -0.01]; Pinteraction = 0.0479). Childhood obesity also modified the associations between BW and plasma levels of 14 proteins (e.g., IL15RA, MCP1, and XCL1; Pinteraction < 0.05).
CONCLUSIONS: We identified associations between lower BW and adverse metabolic phenotypes, particularly insulin resistance, blood pressure, and altered plasma protein levels, which were more pronounced in children with obesity. Developing effective prevention and treatment strategies for this group is needed to reduce the risk of future CMD.
