IntroductionStunting is a height-for-age (Z-score) less than minus two standard deviations below the mean of reference standard. It is the most important sign of long-term chronic undernutrition and public health problem in Ethiopia. However, little information was known regarding determinants of stunting among adolescents since it had mostly been investigated in late infancy, especially among children under the age of five. Therefore, identifying determinants of stunting among adolescent girl is still crucial.ObjectiveTo identify determinants of stunting among adolescent girls in schools of Digo Tsion Town, Northwest Ethiopia, 2022.Methods and materialsCase-control study was conducted among 417 adolescent girls (104 cases and 313 controls) in schools of Digo Tsion Town with computer generated simple random sampling technique. World Health Organization Anthroplus 2007 software was used for analyzing anthropometrics data. Data was collected by epicollect5 mobile application through interview by using structured questionnaire. The data was entered in epi data 4.6 and exported into Statistical Package for Social Science version 26. Variables with p- value ≤ 0.25 in bivariable analysis were candidate for multivariable analysis. Model fitness was checked by Hosmer and Lemon Show fitness of test. Variables having a P-value ResultsA total of 409 (100 cases and 309 controls) adolescent girls participated, with a response rate of 96% for cases and 98.72% for controls. Food insecurity (AOR = 2.13, CI [1.15, 3.93]), low dietary diversity score (AOR = 1.99, CI [1.06, 3.73]), drinking coffee/tea immediately while eating meals (AOR = 2.19, CI [1.22, 3.95]), not getting nutritional counsel (AOR = 2.07, CI [1.17, 3.66]), chronic illness (AOR = 3.78, CI [1.16, 12.3]), and not visited by health extension workers at home (AOR = 1.85, CI [1.03, 3.31]) were statistically significant determinants of stunting.ConclusionStunting among adolescents is influenced by a low dietary diversity score, a food-insecure household, drinking coffee or tea immediately while eating a meal, not receiving nutritional counseling, having a chronic illness, and not being visited by health extension workers at home. Future researchers would do better to undertake prospective studies. Health extension workers are better able to provide nutritional counsel for adolescent.

### 研究背景
发育迟缓（Stunting）指身高别年龄Z评分（height-for-age Z-score）低于参考标准均值减2个标准差，是埃塞俄比亚长期慢性营养不良最重要的体征，也是该国突出的公共卫生问题。既往相关研究多聚焦于婴儿后期尤其是5岁以下儿童的发育迟缓影响因素，针对青少年群体的相关研究较为匮乏，因此明确在校青春期女性发育迟缓的影响因素仍具有重要公共卫生意义。

### 研究目的
本研究旨在明确2022年埃塞俄比亚西北部迪戈齐翁镇在校青春期女性的发育迟缓影响因素。

### 研究方法与材料
本研究采用病例对照研究设计，通过计算机生成简单随机抽样方法，在迪戈齐翁镇各级学校招募417名青春期女性参与者（其中病例组104人，对照组313人）。采用世界卫生组织Anthroplus 2007软件处理人体测量学数据；通过结构化问卷开展面对面访谈，利用epicollect5移动应用程序完成数据采集。研究数据先录入Epi Data 4.6软件，随后导出至社会科学统计软件包（SPSS）26版进行统计分析。双变量分析中P值≤0.25的变量纳入多变量分析候选集，采用霍斯默-莱梅肖（Hosmer-Lemeshow）拟合优度检验评估回归模型的拟合效果，最终以多变量分析中P<0.05的变量作为具有统计学意义的影响因素。

### 研究结果
最终共有409名青春期女性完成全部研究流程（病例组100人，对照组309人），病例组应答率为96%，对照组应答率为98.72%。多变量逻辑回归分析结果显示，粮食不安全（调整后优势比[AOR]=2.13，95%置信区间[CI]=1.15~3.93）、膳食多样性评分偏低（AOR=1.99，95%CI=1.06~3.73）、进餐时即刻饮用咖啡或茶（AOR=2.19，95%CI=1.22~3.95）、未获得专业营养咨询（AOR=2.07，95%CI=1.17~3.66）、患有慢性疾病（AOR=3.78，95%CI=1.16~12.3）以及未接受居家卫生推广人员（health extension workers）访视（AOR=1.85，95%CI=1.03~3.31）为青春期女性发育迟缓的独立危险因素。

### 研究结论
本研究证实，青春期女性发育迟缓受膳食多样性评分偏低、家庭粮食不安全、进餐时即刻饮用咖啡/茶、未获得营养咨询、慢性疾病以及未接受居家卫生推广人员访视等多重因素影响。建议未来开展前瞻性队列研究进一步验证相关结论，同时卫生推广人员应强化针对青春期女性群体的营养咨询服务，以降低该群体发育迟缓的发生风险。
