The scope of this systematic review was to compare the food insecurity scales validated and used in the countries in Latin America and the Caribbean, and analyze the methods used in validation studies. A search was conducted in the Lilacs, SciELO and Medline electronic databases. The publications were pre-selected by titles and abstracts, and subsequently by a full reading. Of the 16,325 studies reviewed, 14 were selected. Twelve validated scales were identified for the following countries: Venezuela, Brazil, Colombia, Bolivia, Ecuador, Costa Rica, Mexico, Haiti, the Dominican Republic, Argentina and Guatemala. Besides these, there is the Latin American and Caribbean scale, the scope of which is regional. The scales ranged from the standard reference used, number of questions and diagnosis of insecurity. The methods used by the studies for internal validation were calculation of Cronbach's alpha and the Rasch model; for external validation the authors calculated association and /or correlation with socioeconomic and food consumption variables. The successful experience of Latin America and the Caribbean in the development of national and regional scales can be an example for other countries that do not have this important indicator capable of measuring the phenomenon of food insecurity.
本系统评价的范围是比较拉丁美洲和加勒比地区各国已验证并使用的粮食不安全量表，并分析验证研究中使用的方法。在Lilacs、SciELO和Medline电子数据库中进行了检索。通过标题和摘要对出版物进行预先筛选，随后进行全文阅读。在审查的16325项研究中，选出了14项。为以下国家确定了12个经过验证的量表：委内瑞拉、巴西、哥伦比亚、玻利维亚、厄瓜多尔、哥斯达黎加、墨西哥、海地、多米尼加共和国、阿根廷和危地马拉。除此之外，还有拉丁美洲和加勒比量表，其范围是区域性的。这些量表在使用的标准参考、问题数量和不安全诊断方面存在差异。研究用于内部验证的方法是计算克朗巴哈系数和拉施模型；用于外部验证时，作者计算了与社会经济和食物消费变量的关联和/或相关性。拉丁美洲和加勒比地区在制定国家和区域量表方面的成功经验可以为其他没有这一衡量粮食不安全现象的重要指标的国家提供范例。
