In this paper, potential underlying mechanisms for massage therapy effects on preterm infant weight gain are reviewed. Path analyses are presented suggesting that: (1) increased vagal activity was associated with (2) increased gastric motility, which, in turn, was related to (3) greater weight gain; and (4) increased IGF-1 was related to greater weight gain. The change in vagal activity during the massage explained 49% of the variance in the change in gastric activity. And, the change in vagal activity during the massage explained 62% of the variance in the change in insulin. That the change in gastric activity was not related to the change in insulin suggests two parallel pathways via which massage therapy leads to increased weight gain: (1) insulin release via the celiac branch of the vagus; and (2) increased gastric activity via the gastric branch of the vagus.
本文回顾了按摩疗法对早产儿体重增加的潜在作用机制。通过路径分析表明：（1）迷走神经活动增加与（2）胃动力增加相关，而胃动力增加又与（3）体重增加相关；（4）IGF-1 增加与体重增加相关。按摩过程中迷走神经活动的变化解释了胃活动变化的 49%。而且，按摩过程中迷走神经活动的变化解释了胰岛素变化的 62%。胃活动的变化与胰岛素的变化无关，这表明按摩疗法通过两条平行途径导致体重增加：（1）通过迷走神经的腹腔分支释放胰岛素；（2）通过迷走神经的胃分支增加胃动力。
