Empirical data indicate that the maternal diet composition has a direct impact on foetal fat mass and resulting birth weights. Weight-bearing maternal exercise influences the placental volume, which has also been correlated to birth weight. A foetal energy balance equation, based on the first law of thermodynamics, that incorporates maternal diet and exercise is developed. Model parameters and validity are evaluated using published data.
实证数据表明,母亲的饮食构成对胎儿脂肪量和出生体重有直接影响。负重的母亲运动影响胎盘体积,而胎盘体积也与出生体重相关。基于热力学第一定律,构建了一个纳入母亲饮食和运动的胎儿能量平衡方程。使用已发表的数据评估模型参数和有效性。
