Purpose

The prevalence of eating disorders (EDs) in young children remains relatively unknown. Here, we aimed to assess the prevalence of anorexia nervosa (AN), bulimia nervosa (BN), binge ED (BED), and their subclinical derivatives, among 10- to 11-year-old children in the United States.

Methods

Cross-sectional data from the year 1 sample of the nationwide Adolescent Cognitive Brain Development study were extracted, and unadjusted prevalence of EDs was reported, as per DSM-5 criteria.

Results

Among 10- to 11-year-old children in the United States, no cases of AN were reported. The prevalence of BN was negligible, whereas the prevalence of BED was 1.1%. The prevalence of subclinical AN, BN, and BED was 6%, 0.2%, and 0.5%, respectively.

Discussion

BED is the most prevalent ED subtype among preadolescent children in the United States, although subclinical markers for all ED subtypes are evident in this age range.

美国青春期前饮食失调的患病率

目的

幼儿饮食失调（EDs）的患病率仍然相对未知。在这里，我们旨在评估美国 10 至 11 岁儿童中神经性厌食症 (AN)、神经性贪食症 (BN)、暴食症 (BED) 及其亚临床衍生物的患病率。

方法

提取了全国青少年认知大脑发育研究的第 1 年样本的横断面数据，并根据 DSM-5 标准报告了未经调整的 ED 患病率。

结果

在美国 10 至 11 岁的儿童中，没有报告 AN 病例。BN 的患病率可以忽略不计，而 BED 的患病率为 1.1%。亚临床 AN、BN 和 BED 的患病率分别为 6%、0.2% 和 0.5%。

讨论

BED 是美国青春期前儿童中最普遍的 ED 亚型，尽管所有 ED 亚型的亚临床标志物在该年龄范围内都很明显。
