To compare the macronutrient intake of females with or without a history of anorexia nervosa (AN) at three times: two years and one year before the onset of AN, and during the first year of the illness.
Prospective cohort study with 3-day food intake records collected over 10 years. Subjects were 154 white females (aged 9 or 10 years at study entry), of whom 14 had AN and 140 were healthy females matched for age at study entry and parental education.
Compared with the healthy girls, girls with AN reported significantly lower total energy intake and fat intake during the first year of the illness; the lower total energy intake was evident already at the 1-year (but not the 2-year) pre-onset assessment.
To identify AN early on, health practitioners caring for adolescent girls should inquire about food intake and reluctance to eat certain foods, especially those containing fat.
比较有或没有神经性厌食症（AN）病史的女性在三个时间点的常量营养素摄入量：AN发病前两年和一年，以及患病第一年。
前瞻性队列研究，收集了10年期间3天的食物摄入量记录。研究对象为154名白人女性（研究开始时年龄为9或10岁），其中14人患有AN，140名健康女性在研究开始时年龄和父母教育程度相匹配。
与健康女孩相比，患有AN的女孩在患病第一年报告的总能量摄入量和脂肪摄入量显著较低；较低的总能量摄入量在发病前1年（而非2年）的评估中就已明显。
为了早期识别AN，照顾青春期女孩的健康从业者应询问食物摄入量以及是否不愿吃某些食物，尤其是那些含脂肪的食物。
