A screening study was conducted to identify malnutrition in gastroenterology outpatients and to ascertain whether poor food intake is a contributing factor. A 48-hour recall method was used to collect dietary data from 154 patients (87 women and 67 men). Fourteen (16%) of the women and 8 (12%) of the men were classified as having protein-energy malnutrition (PEM) on the basis of abnormal anthropometric measurements or low serum albumin concentration. PEM was found in several diagnostic groups, but 9 of the 14 malnourished women had Crohn's disease. Protein undernutrition was more evident in women; calorie undernutrition was more evident in men. More women than men had low serum albumin levels. Low hemoglobin levels were particularly prevalent among patients with Crohn's disease. Many of the patients, especially women, had "inadequate" and "marginal" intakes of folate, vitamin A, thiamin, and calcium according to Nutrition Canada interpretive standards. The intake of iron was particularly poor among women: 59% of the intakes of female patients were classified as inadequate (less than 10 mg/day). Ten of the 14 female patients with PEM had inadequate iron intakes. Serum folates of less than 5 ng/ml were present in 72% of the women and 77% of the men. The data suggest that gastrointestinal outpatients are at high risk of malnutrition and that one of the factors contributing to the problem is inadequate food intake.
开展了一项筛查研究，以确定胃肠病门诊患者中的营养不良情况，并确定食物摄入量不足是否为一个促成因素。采用48小时回顾法收集了154例患者（87名女性和67名男性）的饮食数据。根据人体测量异常或血清白蛋白浓度低，14名（16%）女性和8名（12%）男性被归类为患有蛋白质 - 能量营养不良（PEM）。在几个诊断组中都发现了PEM，但14名营养不良的女性中有9名患有克罗恩病。蛋白质营养不良在女性中更为明显；热量营养不良在男性中更为明显。血清白蛋白水平低的女性比男性更多。血红蛋白水平低在克罗恩病患者中尤为普遍。根据加拿大营养学会的解释标准，许多患者，尤其是女性，叶酸、维生素A、硫胺素和钙的摄入量“不足”且“处于边缘水平”。女性的铁摄入量尤其低：女性患者59%的摄入量被归类为不足（低于10毫克/天）。14名患有PEM的女性患者中有10名铁摄入量不足。72%的女性和77%的男性血清叶酸水平低于5纳克/毫升。数据表明，胃肠病门诊患者存在营养不良的高风险，导致该问题的因素之一是食物摄入量不足。
