This article aims to identify the methods used to assess household food availability in studies on food and nutritional security and to discuss its methodological aspects. Systematic review elaborated according to the PRISMA method. We searched at PubMed; Scielo and Lilacs databases, and studies that used methods of assessing the availability of food at home were included. In the end, 19 papers composed the review. Food availability was predominantly assessed for a seven days period and from a single data measurement. Other variables were also observed in the studies, such as socio-demographic data and expenditure on food. Among the limitations to assess the food availability at home, we can highlight the difficulty in measuring the food distribution among family members and the lack of information on the variability of this availability. Such assessment can be improved by investigating the strengths and weaknesses of the instruments for greater detail and accuracy of the information. We recommend the development and validation of specific instruments capable of effectively measure the food availability at the household level.
本文旨在识别在食品和营养安全研究中评估家庭食物可获得性的方法，并讨论其方法学方面。根据 PRISMA 方法进行系统评价。我们在 PubMed、Scielo 和 Lilacs 数据库中进行了搜索，并纳入了使用评估家庭食物可获得性方法的研究。最终，有 19 篇论文组成了综述。食物可获得性主要在七天的时间内并通过单次数据测量进行评估。研究中还观察到其他变量，如社会人口统计学数据和食品支出。在家中评估食物可获得性的限制因素包括，难以衡量家庭成员之间的食物分配以及缺乏关于这种可获得性的可变性的信息。通过研究仪器的优缺点，可以更详细和准确地获取信息，从而提高这种评估的准确性。我们建议开发和验证特定的仪器，以有效地衡量家庭层面的食物可获得性。
