To assess vitamin D, folate, vitamin B, and iron status in Old Order Anabaptist (OOA) pregnant/postpartum women. Blood was analyzed for plasma 25 hydroxy vitamin D (25(OH)D), red blood cell (RBC) folate, serum vitamin B, and iron status indicators. Dietary intakes (food and supplements) from 3-day estimated records were compared to Dietary Reference Intakes and Canada's Food Guide (2007). Fifty women participated in this descriptive cross-sectional study. Concentrations of 25(OH)D were low (<50 nmol/L for 20% and < 75 nmol/L for 63%); 42% had total vitamin D intakes < estimated average requirement (EAR). All women had RBC folate above the 1360 mmol/L cut-off. Nineteen percent had folate intakes <EAR; 80% had folic acid supplement intakes >upper limit. One woman had low serum vitamin B (<148 pmol/L); serum vitamin B was high (>652 pmol/L) for 24%. None had vitamin B intakes <EAR; intakes were high compared to the recommended dietary intake. One woman had low hemoglobin; 13% had ferritin <15 μg/L. Thirteen percent had total iron intake <EAR. Overall, dietary intake and serum micronutrient status of OOA pregnant and postpartum women in our study were similar to those reported in previous studies of Canadian women. While some women had low intakes of vitamin D and iron, most had high intakes of folate and vitamin B. These findings provide guidance to ensure appropriate dietary and supplement intakes in this potentially vulnerable and rarely studied population.
评估旧秩序阿米什（OOA）孕妇/产后妇女的维生素 D、叶酸、维生素 B 和铁状况。分析血液中的血浆 25 羟维生素 D（25（OH）D）、红细胞（RBC）叶酸、血清维生素 B 和铁状况指标。将 3 天估计记录的膳食摄入量（食物和补充剂）与膳食参考摄入量和加拿大食品指南（2007 年）进行比较。50 名妇女参与了这项描述性横断面研究。25（OH）D 浓度较低（<50 nmol/L 占 20%，<75 nmol/L 占 63%）；42%的人总维生素 D 摄入量<估计平均需求量（EAR）。所有妇女的 RBC 叶酸均高于 1360 mmol/L 截止值。19%的人叶酸摄入量<EAR；80%的人叶酸补充剂摄入量>上限。一名妇女血清维生素 B 水平较低（<148 pmol/L）；血清维生素 B 水平较高（>652 pmol/L）占 24%。没有人的维生素 B 摄入量<EAR；与推荐的膳食摄入量相比，摄入量较高。一名妇女血红蛋白低；13%的人铁蛋白<15 μg/L。13%的人总铁摄入量<EAR。总的来说，我们研究中 OOA 孕妇和产后妇女的膳食摄入和血清微量营养素状况与以前对加拿大妇女的研究报告相似。虽然一些妇女维生素 D 和铁的摄入量较低，但大多数妇女叶酸和维生素 B 的摄入量较高。这些发现为确保这一潜在脆弱且研究甚少的人群获得适当的膳食和补充剂摄入量提供了指导。
