Little is known about the prevalence of DSM-5 eating disorders (EDs) in adolescents. In Norway, the most recent community-based prevalence study in adolescents was published more than 20 years ago. The aim of this study was to assess the prevalence of DSM-5 EDs in Norwegian adolescents using a two-phase design.
A total of 1558 upper secondary school students (827 girls and 730 boys) (ages 16-19) were screened for at-risk ED pathology using the Eating Disorder Examination-Questionnaire short version (EDE-QS). A sub-sample of 99 adolescents (87 girls and 12 boys) subsequently participated in a clinical interview using the Eating Disorder Assessment for DSM-5 (EDA-5).
Eating pathology was common, with 19.9% of participants scoring at or above the applied EDE-QS cut-off. The estimated prevalence of any ED was 9.4% in the total sample, and 16.4% in girls. The number of boys who took part in the diagnostic interview was low, thus, diagnostic data from boys were not analyzed separately. Prevalence estimates of AN, BN, BED, and OSFED in girls were 2.7%, 1.1%, 1.9%, and 10.7%. Atypical AN was the most frequently assigned diagnosis in girls.
Sampling biases limit generalizability of results. Additional population-based studies are warranted to assess the prevalence of EDs in Norwegian youth.
In this study, 1558 adolescents, aged 16-19, were screened for ED pathology. A subsample completed a diagnostic interview using DSM-5 criteria. Results showed that one in five adolescents displayed problematic eating behaviors and cognitions. The estimated prevalence rate of any ED was 9.4%. Sampling biases limit generalizability of results. Additional population-based studies are warranted to assess the prevalence of EDs in Norwegian youth.
目前对于 DSM-5 饮食障碍（ED）在青少年中的流行情况知之甚少。在挪威，最近一次基于社区的青少年流行情况研究是在 20 多年前发表的。本研究旨在使用两阶段设计评估挪威青少年中 DSM-5 ED 的流行情况。
共有 1558 名高中生（827 名女生和 730 名男生）（年龄 16-19 岁）接受了饮食障碍检查问卷短版（EDE-QS）的 ED 风险病理筛查。随后，一个 99 名青少年的亚样本（87 名女生和 12 名男生）接受了 DSM-5 饮食障碍评估（EDA-5）的临床访谈。
饮食病理学很常见，有 19.9%的参与者的 EDE-QS 得分在应用的分界值以上。总样本中任何 ED 的估计患病率为 9.4%，女生为 16.4%。参与诊断访谈的男生人数较少，因此，未单独分析男生的诊断数据。女生的 AN、BN、BED 和 OSFED 的患病率估计值分别为 2.7%、1.1%、1.9%和 10.7%。非典型 AN 是女生中最常诊断的疾病。
抽样偏差限制了结果的普遍性。需要进行更多的基于人群的研究来评估挪威青少年中 ED 的流行情况。
在这项研究中，对 1558 名年龄在 16-19 岁的青少年进行了 ED 病理筛查。一个亚样本使用 DSM-5 标准完成了诊断访谈。结果表明，五分之一的青少年表现出有问题的饮食行为和认知。估计任何 ED 的患病率为 9.4%。抽样偏差限制了结果的普遍性。需要进行更多的基于人群的研究来评估挪威青少年中 ED 的流行情况。
