Bariatric surgery is increasingly offered to women of childbearing age and significantly reduces food intake and nutrient absorption. During pregnancy, associated risks, including micronutrient deficiency, are accentuated. This study describes maternal dietary intake and adherence to dietary recommendations in pregnant women with a history of bariatric surgery. Women aged 18-45 with singleton pregnancies post-bariatric surgery were recruited at <23 weeks of gestation and followed until birth. Dietary intake was measured using three non-consecutive 24 h recalls at enrolment and at 28 and 36 weeks using the standardized tool ASA24-Australia. Micronutrient supplementation dose and adherence was reported using the Brief Medication Adherence Questionnaire. Mean macronutrient intake was calculated from all diet recalls. Micronutrient intake was determined from diet recalls and from supplementation. Intake was compared to the recommended daily intakes for pregnancy. Sixty-three women participated in the study. The participants met 65 ± 17.3% (mean ± SD) of estimated energy requirements, 53(23)% (median(IQR)) of fiber requirements, and exceeded fat and saturated fat recommendations. Dietary intake levels of iron, folate, zinc, calcium, and vitamin A were below recommended levels. Gastric bypass recipients consumed significantly less folate ( = 0.008), vitamin A ( = 0.035), and vitamin E ( = 0.027) than women post-gastric sleeve or gastric band. Multivitamins were used by 80% (n = 55) of participants at study enrolment, which increased their mean intake of all micronutrients to meet recommendations. Women who conceive post-bariatric surgery may require targeted support to meet the recommended nutrient intake. Micronutrient supplementation enables women to meet nutrient recommendations for pregnancy and is particularly important for gastric bypass recipients.
减肥手术越来越多地应用于育龄妇女，它能显著减少食物摄入量和营养吸收。在怀孕期间，包括微量营养素缺乏在内的相关风险会更加突出。本研究描述了有减肥手术史的孕妇的孕产妇饮食摄入量以及对饮食建议的依从性。招募了年龄在18 - 45岁、单胎妊娠且有减肥手术史的妇女，在妊娠23周前入组并随访至分娩。在入组时以及妊娠28周和36周时，使用标准化工具ASA24 - 澳大利亚版，通过三次非连续的24小时饮食回顾来测量饮食摄入量。使用简短药物依从性问卷报告微量营养素补充剂量和依从性。从所有饮食回顾中计算平均宏量营养素摄入量。从饮食回顾和补充剂中确定微量营养素摄入量。将摄入量与孕期推荐的每日摄入量进行比较。63名妇女参与了该研究。参与者满足了估计能量需求的65±17.3%（平均值±标准差）、纤维需求的53(23)%（中位数（四分位间距）），但超过了脂肪和饱和脂肪的推荐量。铁、叶酸、锌、钙和维生素A的饮食摄入量低于推荐水平。接受胃旁路手术的妇女比接受胃袖状切除术或胃束带术的妇女摄入的叶酸（P = 0.008）、维生素A（P = 0.035）和维生素E（P = 0.027）显著更少。80%（n = 55）的参与者在研究入组时使用了多种维生素，这使她们所有微量营养素的平均摄入量增加到符合推荐水平。有减肥手术史后怀孕的妇女可能需要有针对性的支持以满足推荐的营养素摄入量。微量营养素补充能使妇女满足孕期的营养素推荐量，对接受胃旁路手术的妇女尤为重要。
