The purpose of this review was to estimate the prevalence of screen-based disordered eating (SBDE) and several potential risk factors in university undergraduate students around the world.
An electronic search of nine data bases was conducted from the inception of the databases until 1st October 2021. Disordered eating was defined as the percentage of students scoring at or above established cut-offs on validated screening measures. Global data were also analyzed by country, research measure, and culture. Other confounders in this review were age, BMI, and sex.
Using random-effects meta-analysis, the mean estimate of the distribution of effects for the prevalence of SBDE among university students (K = 105, N = 145,629) was [95% CI] = 19.7% [17.9%; 21.6%], I = 98.2%, Cochran's Q p value = 0.001. Bayesian meta-analysis produced an estimate of 0.24, 95% credible intervals [0.20, 0.30], τ = 92%. Whether the country in which the students were studying was Western or non-Western did not moderate these effects, but as either the mean BMI of the sample or the percentage of the sample that was female increased, the prevalence of SBDE increased.
These findings support previous studies indicating that many undergraduate students are struggling with disordered eating or a diagnosable eating disorder, but are neither receiver effective prevention nor accessing accurate diagnosis and available treatment. It is particularly important to develop ever more valid ways of identifying students with high levels of disordered eating and offering them original or culturally appropriate and effective prevention or early treatment.

本综述的目的是评估全球大学生中屏幕相关的饮食障碍（SBDE）的流行率和一些潜在的风险因素。
从数据库创建之初到 2021 年 10 月 1 日，我们对九个数据库进行了电子检索。饮食障碍的定义为在经过验证的筛查测量中得分等于或高于既定截止值的学生比例。本综述还按国家、研究措施和文化对全球数据进行了分析。本综述中的其他混杂因素为年龄、BMI 和性别。
使用随机效应荟萃分析，105 项研究（K=105，N=145629）的大学生 SBDE 流行率的效应分布的平均估计值为[95%置信区间]为 19.7% [17.9%；21.6%]，I=98.2%，Cochran's Q p 值=0.001。贝叶斯荟萃分析得出的估计值为 0.24，95%可信区间[0.20，0.30]，τ=92%。学生所在的国家是西方还是非西方并不能调节这些效应，但无论是样本的平均 BMI 还是女性样本的比例增加，SBDE 的流行率都会增加。
这些发现支持了之前的研究，表明许多大学生正在与饮食障碍或可诊断的饮食障碍作斗争，但既没有接受有效的预防措施，也没有获得准确的诊断和可获得的治疗。特别重要的是，要开发出更有效的方法来识别患有严重饮食障碍的学生，并为他们提供原始的或文化上合适且有效的预防或早期治疗。
