Abstract

Anorexia nervosa (AN) and zinc deficiency, found most frequently in young females, have a number of symptoms in common. These include weight loss, alterations in taste and appetite, depression, and amenorrhea. Approximately half of anorexia nervosa patients (ANs) are vegetarian (VANs), a practice that may increase their risk for zinc deficiency. This study compared the dietary intake of zinc and related nutrients in 9 outpatient VANs with that of 11 outpatient nonvegetarian patients with anorexia nervosa (NVANs). VANs reported significantly lower (p < .05) dietary intakes of zinc, fat, and protein, and a significantly higher (p < .05) intake of calories from carbohydrates than NVANs. There were no significant differences between the groups in dietary intake of calories, calcium, copper, iron, or magnesium. These findings indicate that zinc intake should be routinely assessed in VANs and that zinc supplementation of their diets may be indicated.

摘要

神经性厌食症（AN）和锌缺乏症在年轻女性中最为常见，它们有许多共同症状。这些症状包括体重减轻、味觉和食欲改变、抑郁以及闭经。大约一半的神经性厌食症患者（ANs）是素食者（VANs），这种饮食习惯可能会增加他们锌缺乏的风险。本研究比较了9名门诊素食神经性厌食症患者（VANs）和11名门诊非素食神经性厌食症患者（NVANs）的锌及相关营养素的饮食摄入量。VANs报告的锌、脂肪和蛋白质的饮食摄入量显著低于（p < .05）NVANs，而碳水化合物热量的摄入量显著高于（p < .05）NVANs。两组在热量、钙、铜、铁或镁的饮食摄入量上没有显著差异。这些发现表明，应常规评估VANs的锌摄入量，可能需要在其饮食中补充锌。
