Although food cravings and aversions are commonly experienced by pregnant women, the degree to which they persist in the postpartum period is unknown. This study examines this issue in both lactating and nonlactating women. A random sample of 463 subjects was selected from all prenatal patients receiving care at a large health maintenance organization (HMO). Even though almost all of the subjects reported craving some food or beverage during the last trimester of pregnancy and half reported some aversion, those phenomena dropped markedly in the postpartum period. Evaluation of dietary quality as related to food cravings revealed no clear association; that is, the data provided no evidence to support the hypothesis that cravings are caused by dietary deficiencies or that they result in significantly augmented intake of key nutrients found in those foods. Overall, food cravings and aversions do not continue into the postpartum period at a higher rate than one would expect in the adult female population; manifestation of food cravings/aversions is not related to dietary quality.
尽管孕妇普遍会出现食物渴望和厌恶的情况，但它们在产后持续的程度尚不清楚。本研究在哺乳期和非哺乳期女性中探讨了这个问题。从一家大型健康维护组织（HMO）接受护理的所有产前患者中随机抽取了463名受试者。尽管几乎所有受试者都报告在妊娠晚期渴望某些食物或饮料，且有一半报告有某种厌恶情绪，但这些现象在产后明显减少。对与食物渴望相关的饮食质量评估未发现明显关联；也就是说，数据没有提供证据支持食物渴望是由饮食缺乏引起的这一假设，也没有证据表明它们会导致这些食物中关键营养素的摄入量显著增加。总体而言，食物渴望和厌恶在产后持续的发生率并不高于成年女性人群的预期；食物渴望/厌恶的表现与饮食质量无关。
