In Ethiopia, there are different pocket studies that assessed adolescent undernutrition which came up with inconsistent and inconclusive findings. Therefore, estimating the pooled prevalence and associated factors of the adolescent undernutrition using meta-analysis is crucial in Ethiopia. A systematic review of eligible articles was conducted using preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines. A comprehensive searching of the literature was made in Pub Med, Scopus, Google, Google Scholar, Cochrane Library and CINAHL. The quality of the articles included in the review was assessed using the Newcastle-Ottawa Scale (NOS) for non-randomized studies in meta-analyses. The pooled prevalence and odds ratio of the associated factors with their 95% confidence interval was computed using STATA version 14 software. Twenty-two studies were included in the meta-analysis with a total of 17,854 adolescents. Using the random-effects model analysis, the pooled prevalence of stunting and underweight was 20.7% (95% CI: 16.08, 25.33) and 27.5% (95% CI: 17.9, 57.14), respectively. Rural residence, having family size≥5, households with an unprotected water source for drinking and food-insecure household were significant associated factors for adolescent stunting. Early adolescent age (10–14 years), family size≥5, food-insecure household, lack of latrine, WHO diet diversity score < 4, mother educational status (with no formal education) were significant associated factors for adolescent underweight. Adolescent undernutrition remains one of the most important public health problems in Ethiopia. Almost a quarter of Ethiopian adolescents were affected by stunting and underweight. Large family size, rural residence and unprotected source of drinking water were the associated factors for adolescent stunting. Similarly, large family size, early age of adolescent, lack of latrine, low dietary diversity score, mother illiteracy, and food insecure household were the associated factors for adolescent underweight. It would be good to give high emphasis on adolescent undernutrition and it is important to address the above mentioned associated factors during adolescent nutritional interventions in Ethiopia.

埃塞俄比亚青少年营养不良的患病率及相关因素：系统评价和荟萃分析

在埃塞俄比亚，有不同的袖珍研究评估了青少年营养不良的情况，但得出的结果不一致且不确定。因此，在埃塞俄比亚，利用荟萃分析估计青少年营养不良的汇总患病率和相关因素至关重要。使用系统评价和荟萃分析（PRISMA）指南的首选报告项目对符合条件的文章进行了系统评价。在 Pub Med、Scopus、Google、Google Scholar、Cochrane Library 和 CINAHL 中对文献进行了全面检索。使用纽卡斯尔-渥太华量表（NOS）对荟萃分析中的非随机研究评估纳入综述的文章的质量。使用 STATA 14 版软件计算相关因素的汇总患病率和优势比及其 95% 置信区间。荟萃分析纳入了 22 项研究，总计 17,854 名青少年。使用随机效应模型分析，发育迟缓和体重不足的合并患病率分别为 20.7% (95% CI: 16.08, 25.33) 和 27.5% (95% CI: 17.9, 57.14)。农村居住、家庭人口≥5人、饮用水源未受保护的家庭和粮食不安全的家庭是青少年发育迟缓的显着相关因素。青春期早期（10-14岁）、家庭规模≥5人、家庭粮食不安全、缺乏厕所、世界卫生组织饮食多样性评分<4、母亲教育状况（未受过正规教育）是青少年体重不足的显着相关因素。青少年营养不良仍然是埃塞俄比亚最重要的公共卫生问题之一。近四分之一的埃塞俄比亚青少年受到发育迟缓和体重不足的影响。家庭规模大、居住在农村和饮用水源不受保护是青少年发育迟缓的相关因素。同样，家庭规模大、青少年年龄小、缺乏厕所、饮食多样性得分低、母亲文盲和家庭粮食不安全是青少年体重不足的相关因素。高度重视青少年营养不良问题是好事，在埃塞俄比亚青少年营养干预期间解决上述相关因素也很重要。
