We examined diet quality and intake of pregnancy-specific micronutrients among pregnant American Indian women in the Northern Plains.
We conducted an analysis of nutrition data from the Prenatal Alcohol and SIDS and Stillbirth (PASS) Network Safe Passage Study and the PASS Diet Screener study (N = 170). Diet intake, including dietary supplementation, was assessed by using three 24-hour recalls conducted on randomly selected, nonconsecutive days. Diet intake data were averaged across the participant's recalls and scored for 2 dietary indices: the Healthy Eating Index 2010 (HEI-2010) and the Alternate Healthy Eating Index for Pregnancy (AHEI-P). We also assessed nutrient adequacy with Dietary Reference Intakes for pregnancy.
On average, participants were aged 26.9 (standard deviation [SD], 5.5) years with a pre-pregnancy body mass index of 29.8 (SD, 7.5) kg/m. Mean AHEI-P and HEI-2010 scores (52.0 [SD, 9.0] and 49.2 [SD, 11.1], respectively) indicated inadequate adherence to dietary recommendations. Micronutrient intake for vitamins D and K, choline, calcium, and potassium were lower than recommended, and sodium intake was higher than recommended.
Our findings that pregnant American Indian women are not adhering to dietary recommendations is consistent with studies in other US populations. Identifying opportunities to partner with American Indian communities is necessary to ensure effective and sustainable interventions to promote access to and consumption of foods and beverages that support the adherence to recommended dietary guidelines during pregnancy.
我们研究了北美平原地区美国印第安孕妇的饮食质量和特定于妊娠的微量营养素摄入量。
我们对来自产前酒精和 SIDS 及死胎（PASS）网络安全通道研究和 PASS 饮食筛选器研究（N=170）的营养数据进行了分析。饮食摄入，包括饮食补充剂，通过在随机选择的非连续日子进行的 3 次 24 小时回忆来评估。通过参与者回忆的平均值对饮食摄入数据进行评分，并对 2 种饮食指数进行评分：2010 年健康饮食指数（HEI-2010）和妊娠替代健康饮食指数（AHEI-P）。我们还使用妊娠膳食参考摄入量评估了营养素的充足性。
平均而言，参与者的年龄为 26.9 岁（标准差 [SD]，5.5），孕前体重指数为 29.8（SD，7.5）kg/m。平均 AHEI-P 和 HEI-2010 评分（分别为 52.0 [SD，9.0]和 49.2 [SD，11.1]）表明饮食建议的依从性不足。维生素 D 和 K、胆碱、钙和钾的微量营养素摄入量低于推荐量，而钠摄入量高于推荐量。
我们的研究结果表明，美国印第安孕妇没有遵循饮食建议，这与其他美国人群的研究结果一致。有必要与美国印第安社区合作，确定机会，以确保有效和可持续的干预措施，促进在怀孕期间获得和消费支持遵循推荐膳食指南的食物和饮料。
