The dietary habits of 94 pregnant women (median age 26 years) were studied by means of four-day dietary records. Twenty-seven women were followed longitudinally and were observed in the 10-15th, the 24-27th and the 34-37th week of gestation (L-series). The remaining 67 women comprised the A-series, of which 20, 32, and 15 made their records during the 10-15th, 24-27th, and 34-37th week of gestation, respectively. There were no significant differences between the results from these two series. The mean daily energy intake was 2360 kcal and remained unchanged during pregnancy, exceeding by 250 kcal the average intake in non-pregnant women in Gothenburg, studied earlier. The iron intake comprised 1-2 mg of haeme iron, about 10 mg of native non-haeme iron and 5-6 mg of fortificiation iron. The mean iron intake was 7.2 mg/1000 kcal, which is below the recommendation, but it was distributed over the food groups in a manner more favourable for iron absorption than in the average Swedish population. Further effects to improve the diet so as to increase the content of iron and factors known to favour iron absorption are desirable. The results justify the normal practice of prescribing supplement iron in late pregnancy.
通过为期四天的饮食记录，对94名孕妇（中位年龄26岁）的饮食习惯进行了研究。27名孕妇进行了纵向跟踪，在妊娠第10 - 15周、第24 - 27周和第34 - 37周进行观察（L组）。其余67名孕妇组成A组，其中分别有20名、32名和15名孕妇在妊娠第10 - 15周、第24 - 27周和第34 - 37周记录了她们的饮食情况。这两组的结果没有显著差异。平均每日能量摄入量为2360千卡，孕期保持不变，比早前在哥德堡研究的非孕妇平均摄入量高出250千卡。铁摄入量包括1 - 2毫克血红素铁、约10毫克天然非血红素铁和5 - 6毫克强化铁。平均铁摄入量为7.2毫克/1000千卡，低于推荐量，但与瑞典普通人群相比，其在食物组中的分布方式更有利于铁的吸收。进一步改善饮食以增加铁含量以及有利于铁吸收的因素是可取的。这些结果证明了在妊娠晚期常规开铁补充剂的做法是合理的。
