在整个生命过程中,食欲性状会影响食物摄入量和体重增加。这里,我们调查了产妇对遵循健康婴儿喂养指南的态度是否可以改变这种关联.纳入婴儿牛奶试验的544个母婴配方奶喂养二元组的基线数据包括在这个观察中,横截面分析。婴儿的食欲特征(食物反应性和饱腹感反应性),母亲对遵循健康婴儿喂养指南的态度(自我效能,预期结果,意向)和婴儿牛奶摄入量由母亲通过问卷报告。使用标准程序测量婴儿体重。在针对婴儿性别和年龄进行调整的线性回归模型中,评估了母亲态度评分或婴儿食欲特征与婴儿牛奶摄入量和婴儿体重之间的关联。要识别效果修改,模型中加入了母亲态度评分和婴儿食欲性状之间的交互项.婴儿的平均年龄和体重分别为2.3个月(SD=0.9)和5.5公斤(SD=0.9),分别。母亲报告的每日平均婴儿牛奶摄入量为895毫升/天(SD=215)。较高的产妇态度评分与较低的婴儿牛奶摄入量(Beta=-68.4ml/天/单位(95%CI:96.6,-40.2))和婴儿体重(Beta=-0.13SD/单位(-0.25,-0.02))相关。母亲态度评分显示了婴儿食物反应对婴儿牛奶摄入量的相互作用(p=0.049),和婴儿饱腹感反应对婴儿体重的影响(p=0.01)。在这两种情况下,较高的产妇态度评分减弱了婴儿食欲特征与结局之间的关联.该分析提供了证据,表明母亲对遵循健康婴儿喂养指南的积极态度会减弱婴儿食欲性状对婴儿牛奶摄入量和体重的影响。
Appetitive traits influence food intake and weight gain throughout the life-course. Here, we investigated whether maternal attitudes to following healthy infant feeding
guidelines could modify this association. Baseline data from 544 mother-infant formula-feeding dyads recruited to the Baby Milk Trial were included in this observational, cross-sectional analysis. Infant appetitive traits (food responsiveness and
satiety responsiveness), maternal attitudes to following healthy infant feeding
guidelines (self-efficacy, outcome-expectancy, intentions) and infant milk intakes were reported by mothers through questionnaires. Infant weight was measured using standard procedures. Associations between the maternal attitudes score or infant appetitive traits with infant milk intake and infant weight were evaluated in linear regression models adjusted for infant sex and age. To identify effect modification, the interaction term between the maternal attitudes score and infant appetitive trait was added to the model. Infants\' mean age and weight were 2.3 months (SD = 0.9) and 5.5 kg (SD = 0.9), respectively. The mean daily infant milk intake reported by mothers was 895 ml/day (SD = 215). Higher maternal attitudes score was associated with lower infant milk intake (Beta = -68.4 ml/day/unit (95% CI: 96.6, -40.2)) and infant weight (Beta = -0.13 SD/unit (-0.25, -0.02)). The maternal attitudes score showed interactions with infant food responsiveness on infant milk intake (p = 0.049), and with infant
satiety responsiveness on infant weight (p = 0.01). In both cases, a higher maternal attitudes score attenuated the associations between infant appetitive traits and those outcomes. This analysis provides evidence that positive maternal attitudes to following healthy infant feeding
guidelines attenuate the effects of infant appetitive traits on infant milk intake and body weight.
