The aim of the present study was to assess energy and nutrient intake in a group of women with restrictive AN (r-AN) compared with a control group.
Thirteen r-AN patients and 13 healthy female controls completed 7-d food records. Intake of macro- and micronutrients was compared between the two groups as well as to the Dietary Reference Intake for the Italian Population (LARN) for specific ages. Additionally, the r-AN patients underwent indirect calorimetry for measuring resting energy expenditure (REE).
Total energy intake was significantly lower in the r-AN group than in controls (906 ± 224 vs 1660 ± 139, respectively; P < 0.01). Nutrient composition significantly differed, as well. Mean intake of sodium, phosphorus, and zinc was higher in controls than in the women with r-AN (P < 0.01), but neither group of women met LARN recommendations for potassium, calcium, or iron intake. With respect to vitamins, no significant differences were found for riboflavin or vitamins A, B, or C between groups, whereas levels of other vitamins differed (P < 0.01). Both groups failed to meet the LARN recommendation for vitamin D intake; moreover, none of the r-AN patients met recommended intake levels of vitamin E, thiamine, niacin, and folate.
Intakes reported by r-AN patients did not meet requirements for most micronutrients evaluated in this study and, as expected, both energy needs and specific dietary patterns differed between groups. Therefore, a careful evaluation of food consumption should be recommended to reduce nutritional gaps in these patients. According to these preliminary observations, nutritional counseling, mainly focused on calcium and vitamin D intake, should be suggested for healthy women, as well.
本研究旨在评估一组患有限制性神经性厌食症（r-AN）的女性与对照组相比的能量和营养摄入情况。
13名r-AN患者和13名健康女性对照完成了7天的食物记录。比较了两组之间的宏量营养素和微量营养素摄入量以及意大利特定年龄人群的膳食参考摄入量（LARN）。此外，r-AN患者接受了间接测热法以测量静息能量消耗（REE）。
r-AN组的总能量摄入量显著低于对照组（分别为906±224和1660±139；P<0.01）。营养成分也存在显著差异。对照组钠、磷和锌的平均摄入量高于r-AN女性（P<0.01），但两组女性均未达到LARN关于钾、钙或铁摄入量的建议。关于维生素，两组之间核黄素或维生素A、B或C没有显著差异，而其他维生素水平有所不同（P<0.01）。两组均未达到LARN关于维生素D摄入量的建议；此外，没有一名r-AN患者达到维生素E、硫胺素、烟酸和叶酸的推荐摄入量水平。
r-AN患者报告的摄入量未达到本研究中评估的大多数微量营养素的需求，并且正如预期的那样，两组之间的能量需求和特定饮食模式有所不同。因此，建议仔细评估食物消费以减少这些患者的营养差距。根据这些初步观察结果，也应为健康女性提供主要关注钙和维生素D摄入量的营养咨询。
