Biochemical findings on blood samples from 102 pregnant women in four age groups, 12-17, 18-19, 20-24, and 25-32, are reported. Samples represent 8 antepartum periods of 4 weeks each and 3 postpartum periods over 6 weeks. Blood analyses were carried out for hemoglobin, plasma iron, plasma total protein, glucose, plasma alkaline phosphatase, plasma ascorbic acid, plasma vitamin A and carotene, erythrocyte transketolase as a measure of thiamine status, plasma cholesterol, plasma lipid phosphorus, plasma total fatty acids, and triglyceride fatty acids. For the most part, means of these nutrients were in acceptable ranges for all age groups. Although adolescents had better levels than anticipated, the two younger groups on several occasions had means significantly lower than those of the two older groups, indicating that they needed greater nutritional support during pregnancy than older women.
报告了对102名处于四个年龄组（12 - 17岁、18 - 19岁、20 - 24岁和25 - 32岁）的孕妇血液样本的生化检测结果。样本涵盖了每个为期4周的8个产前阶段以及6周以上的3个产后阶段。对血红蛋白、血浆铁、血浆总蛋白、葡萄糖、血浆碱性磷酸酶、血浆抗坏血酸、血浆维生素A和胡萝卜素、作为硫胺素状态指标的红细胞转酮醇酶、血浆胆固醇、血浆脂质磷、血浆总脂肪酸以及甘油三酯脂肪酸进行了血液分析。在大多数情况下，所有年龄组这些营养素的均值都在可接受范围内。尽管青少年的水平比预期的要好，但两个较年轻的年龄组在若干情况下均值显著低于两个较年长的年龄组，这表明她们在孕期比年长女性需要更多的营养支持。
