This study aimed to understand the protective role of positive mother-infant interactions in the context of food and nonfood behaviors against obesity risk later in life among a cohort of low-income children at high prenatal risk due to maternal substance use during pregnancy.
The sample consisted of 216 mother-infant dyads (49% boys) participating in an ongoing longitudinal study. Mother-infant interactions during a feeding episode and a free-play task were measured at child age 1 and 7 months, respectively. Children's length/height and weight were measured at 1, 7, 13, 24, 36, and 48 months of age; at kindergarten age (approximately 60 months); and in second grade (approximately 84 months). BMI growth trajectories were modeled.
No significant associations were found between mother-child feeding interactions and child BMI trajectories. Maternal warmth (95% CI: -0.020 to -0.0005; P = 0.04) and child positive affect (95% CI: -0.020 to -0.002; P = 0.014) during free play were associated with a more normative child BMI trajectory.
Results from this study indicated that high maternal warmth and child positive affect during play, but not feeding interactions, are associated with reduced obesity risk from infancy to middle childhood in the context of high pre- and postnatal risks.
本研究旨在了解在母亲孕期物质使用导致高产前风险的低收入儿童队列中，积极的母婴互动在食物和非食物行为方面对肥胖风险的保护作用。
该样本包括 216 对母婴（49%为男孩），他们参与了一项正在进行的纵向研究。在婴儿 1 个月和 7 个月时，分别测量了母婴在喂养和自由游戏期间的互动情况。在 1、7、13、24、36 和 48 个月、幼儿园年龄（约 60 个月）和二年级（约 84 个月）时测量了儿童的身高/体重。使用 BMI 生长轨迹模型。
母婴喂养互动与儿童 BMI 轨迹之间没有显著关联。在自由游戏期间，母亲的温暖（95%CI：-0.020 至-0.0005；P=0.04）和儿童的积极情绪（95%CI：-0.020 至-0.002；P=0.014）与更正常的儿童 BMI 轨迹有关。
本研究结果表明，在高产前和产后风险背景下，母亲在游戏期间的温暖和孩子的积极情绪，而不是喂养互动，与从婴儿期到幼儿期肥胖风险降低有关。
