研究母亲孕前体重指数(ppBMI)和妊娠体重增加(GWG)与后代心脏代谢健康的关系。我们在波士顿地区的一个产前队列 Project Viva 中研究了 1,090 对母子。我们测量了 6-10 岁时后代的整体肥胖(DXA 总脂肪;BMI z 分数)和中心肥胖(DXA 躯干脂肪)和 SBP。测定空腹血液 (n=687) 的胰岛素和葡萄糖(用于计算 HOMA-IR)、甘油三酯、瘦素、脂联素、hsCRP 和 IL-6。使用多变量线性回归,我们检查了每 1 SD 母亲 ppBMI 和 GWG 的后代结局差异。调整混杂因素后,ppBMI 每升高 5 kg/m2,总脂肪含量就会增加 0.92 (95% CI: 0.70, 1.14) kg,BMI z 分数增加 0.27 (0.21, 0.32) kg,躯干脂肪增加 0.39 (0.29, 0.49) kg。 ppBMI 还与 HOMA-IR、瘦素、hsCRP、IL-6 和 SBP 呈正相关;并降低脂联素。考虑到混杂因素和 ppBMI 后,每 5 kg GWG 预测后代的肥胖程度更高(0.33 [0.11, 0.54] kg 总脂肪;0.14 [0.04, 0.23] kg 躯干脂肪)和更高的瘦素(6% [0%, 13%])。较重的母亲所生的孩子有更多的整体和中心脂肪以及更大的心脏代谢风险。 GWG 较高的女性的后代肥胖程度更高,瘦素也更高。
To examine the relations of maternal pre-pregnancy body mass index (ppBMI) and gestational weight gain (GWG) with offspring cardiometabolic health. We studied 1,090 mother-child pairs in Project Viva, a Boston-area pre-birth cohort. We measured overall (DXA total fat; BMI z-score) and central adiposity (DXA trunk fat), and SBP in offspring at 6–10 years. Fasting bloods (n=687) were assayed for insulin and glucose (for calculation of HOMA-IR), triglycerides, leptin, adiponectin, hsCRP and IL-6. Using multivariable linear regression, we examined differences in offspring outcomes per 1 SD maternal ppBMI and GWG. After adjustment for confounders, each 5 kg/m2 higher ppBMI corresponded with 0.92 (95% CI: 0.70, 1.14) kg higher total fat, 0.27 (0.21, 0.32) BMI z-score, and 0.39 (0.29, 0.49) kg trunk fat. ppBMI was also positively associated with HOMA-IR, leptin, hsCRP, IL-6, and SBP; and lower adiponectin. Each 5 kg of GWG predicted greater adiposity (0.33 [0.11, 0.54] kg total fat; 0.14 [0.04, 0.23] kg trunk fat) and higher leptin (6% [0%, 13%]) in offspring after accounting for confounders and ppBMI. Children born to heavier mothers have more overall and central fat and greater cardiometabolic risk. Offspring of women with higher GWG had greater adiposity and higher leptin.
