背景资料：全球粮食危机在当地转化为长期粮食不安全的过程中产生不同影响的证据，对于设计针对最弱势群体的粮食安全干预措施至关重要。没有关于发展中国家青少年长期粮食不安全程度或其预测因素的研究。在埃塞俄比亚的粮食价格上涨的背景下，我们假设，在低收入的城市家庭的青少年更有可能遭受慢性粮食不安全比那些在农村地区谁可以直接获得agriculturalproducts.Methods：本报告是基于前两轮的Jimma纵向家庭调查的青年（JLFSY）的数据。采用分层随机抽样方法选择青少年和家庭。共有1911名13-17岁的青少年接受了采访，他们的个人经历的粮食不安全的基线和第二年。多变量Logistic回归分析比较慢性青少年粮食不安全的家庭收入，家庭粮食不安全，和社会人口变量后，一年的following.Results：总体而言，20.5%的青少年粮食不安全的第一轮调查，而粮食不安全的青少年的比例增加到48.4%一年后。在为期一年的跟踪调查期间，一半以上（54.8%）的青年人遇到了暂时的粮食不安全问题-即在第一轮或第二轮调查期间。在随访期间，14.0%的青少年有长期粮食不安全（即两轮都有粮食不安全）。多变量Logistic回归分析显示，城市低收入家庭（OR = 1.69，P = 0.008）和中等收入家庭（OR = 1.80，P = 0.003）的青少年患慢性食物不安全的可能性是高收入家庭的近两倍，而农村和半城市家庭的情况并非如此。青少年女性（P < 0.01）、高抚养比（P < 0.05）和家庭食物不安全（P < 0.001）是城市、半城市和农村地区青少年慢性食物不安全的独立预测因素，而青少年受教育状况与城市地区的慢性食物不安全呈负相关（OR = 0.047，P = 0.002）。
Background: Evidence on the differential impacts of the global food crisis as it translates into chronic food insecurity locally is essential to design food security interventions targeting the most vulnerable population groups. There are no studies on the extent of chronic food insecurity or its predictors among adolescents in developing countries. In the context of increased food prices in Ethiopia, we hypothesized that adolescents in low income urban households are more likely to suffer from chronic food insecurity than those in the rural areas who may have direct access to agricultural products.Methods: This report is based on data from the first two rounds of the Jimma Longitudinal Family Survey of Youth (JLFSY). Both adolescents and households were selected using a stratified random sampling method. A total of 1911 adolescents aged 13-17 years were interviewed on their personal experiences of food insecurity both at baseline and at year two. Multivariable logistic regression analyses were used to compare chronic adolescent food insecurity by household income, household food insecurity, and socio-demographic variables after one year of follow-up.Results: Overall, 20.5% of adolescents were food insecure in the first round survey, while the proportion of adolescents with food insecurity increased to 48.4% one year later. During the one year follow up period, more than half (54.8%) of the youth encountered transient food insecurity - that is, either during the first or the second round survey. During the follow up period, 14.0% of adolescents had chronic food insecurity (i.e. were food insecure at both rounds). Multivariable logistic regression analysis showed that adolescents in the urban households with low (OR = 1.69, P = 0.008) and middle (OR = 1.80, P = 0.003) income tertiles were nearly twice as likely to suffer from chronic food insecurity compared with those in high income tertile, while this was not the case in rural and semi-urban households. Female sex of adolescents (P < 0.01), high dependency ratio (P < 0.05) and household food insecurity (P < 0.001) were independent predictors of chronic adolescent food insecurity in urban, semi-urban, and rural areas, while educational status of the adolescents was negatively associated with chronic food insecurity (OR = 0.047, P = 0.002) in urban areas.
