UNASSIGNED: We evaluated how birth parent obesity 7 y after delivery was associated with child body composition changes and cardiometabolic health in midchildhood and further assessed the influence of the perinatal and postpartum period on associations.
UNASSIGNED: Black and Dominican pregnant individuals were enrolled, and dyads (n = 319) were followed up at child age 7 and 9 y. Measures included, height, weight, waist circumference (WC), and percent body fat (BF%). Multiple linear regression was used to relate postpartum weight status with child outcomes accounting for attrition, and a series of secondary analyses were conducted with additional adjustment for perinatal weight status, gestational weight gain (GWG), and/or long-term weight retention to evaluate how these factors influenced associations.
UNASSIGNED: Almost one-quarter (23%) of birth parents and 24.1% children were classified with obesity at child age 7 y, while at 9 y, 30% of children had obesity. Birth parent obesity at child age 7 y was associated with greater changes, from ages 7 to 9 y, in child BMI z-score (β: 0.13; 95% CI: 0.02, 0.24) and BF% (β: 1.15; 95% CI: 0.22, 2.09) but not obesity at age 9 y. All observed associations crossed the null after additional adjustment for prenatal factors.
UNASSIGNED: Birth parent obesity at 7-y postpartum is associated with greater gains in child BMI z-score and BF% in midchildhood. These associations diminish after accounting for prenatal size, suggesting a lasting impact of the perinatal environment and that interventions supporting families from the prenatal period through childhood are needed.
我们评估了分娩后7年出生父母肥胖与儿童中期身体成分变化和心脏代谢健康的关系,并进一步评估了围产期和产后对这种关系的影响。
■黑人和多米尼加孕妇参加了研究,并在7岁和9岁的儿童进行了随访(n=319)。措施包括,高度,体重,腰围(WC),和身体脂肪百分比(BF%)。使用多元线性回归将产后体重状况与儿童结局联系起来,并进行了一系列二次分析,并对围产期体重状况进行了额外的调整,妊娠期体重增加(GWG),和/或长期体重保持率,以评估这些因素如何影响关联。
近四分之一(23%)的亲生父母和24.1%的儿童在7岁时被归类为肥胖,而在9岁时,30%的儿童患有肥胖症。7岁儿童出生时父母肥胖与更大的变化相关,从7岁到9岁,儿童BMIz评分(β:0.13;95%CI:0.02,0.24)和BF%(β:1.15;95%CI:0.22,2.09),但不包括9岁时的肥胖。在对产前因素进行额外调整后,所有观察到的关联均为零。
产后7岁时出生父母肥胖与儿童BMIz评分和儿童期BF%的增加有关。考虑到产前大小后,这些关联会减弱,提示围产期环境的持久影响,并且需要从产前到儿童期支持家庭的干预措施。
