The objective of this study was to evaluate the meal patterns and nutrient intake of women with bulimia nervosa (BN), and to compare them to clinical variables and recommended dietary allowances (RDA).
The nutrient intake of 50 women with BN was analyzed from 14 day dietary records. The data were compared to the median intakes of a random sample of women and to the RDA. Clinical variables for the women with BN were also available.
Compared to nonbinge episodes per day, binge eating was significantly higher in energy from sucrose, fat, saturated fatty acids (SFA), monounsaturated fatty acids (MUFA) and lower in protein. Compared to the population median, binge eating was significantly lower in percent energy from protein, and higher in percent carbohydrate (CHO), sucrose, SFA, and MUFA, while nonbinge eating was significantly lower in percent energy from fat, SFA, and MUFA. Total intakes were significantly higher in energy and percent energy sucrose compared to the population. Despite significantly lower nonbinge energy intake, calcium, vitamins A and C, iron, and folate were not significantly different to the population median. However, one half or more of the subjects had less than two-thirds the RDA for nonbinge calcium, iron, zinc and for total intake one fourth remained less than two-thirds the RDA for iron and zinc.
Nonbinge eating was characterized by low energy intake and by low intake of iron, calcium, and zinc. Binge eating, characterized by high sucrose and SFA content, overcompensated for these low energy intakes. Where treatment reduces or eliminates binge eating, it should also encourage consumption of regular meals and in particular, consumption of foods rich in zinc and iron.
本研究的目的是评估神经性贪食症（BN）女性的饮食模式和营养摄入情况，并将其与临床变量及推荐膳食摄入量（RDA）进行比较。
通过14天的饮食记录分析了50名BN女性的营养摄入情况。将数据与随机抽取的女性样本的中位数摄入量以及RDA进行比较。BN女性的临床变量数据也可获取。
与每日非暴食发作相比，暴食时来自蔗糖、脂肪、饱和脂肪酸（SFA）、单不饱和脂肪酸（MUFA）的能量显著更高，而蛋白质含量更低。与总体中位数相比，暴食时来自蛋白质的能量百分比显著更低，来自碳水化合物（CHO）、蔗糖、SFA和MUFA的能量百分比更高，而非暴食时来自脂肪、SFA和MUFA的能量百分比显著更低。与总体相比，总摄入量的能量和能量中蔗糖的百分比显著更高。尽管非暴食能量摄入量显著更低，但钙、维生素A和C、铁以及叶酸与总体中位数无显著差异。然而，一半或更多受试者的非暴食钙、铁、锌摄入量不到RDA的三分之二，总体摄入量方面，四分之一受试者的铁和锌摄入量仍不到RDA的三分之二。
非暴食饮食的特点是能量摄入低以及铁、钙和锌的摄入量低。以高蔗糖和SFA含量为特征的暴食，对这些低能量摄入起到了过度补偿作用。在治疗减少或消除暴食时，还应鼓励规律进餐，特别是鼓励摄入富含锌和铁的食物。
