This study sought to describe the changes in the food security status in Brazil before and during its most recent financial and political crisis, as well as to explore associations between food security and socioeconomic factors during the crisis. This cross-sectional study analyzed data from two different sources: the Brazilian National Household Sample Survey for 2004 (n = 112,479), 2009 (n = 120,910), and 2013 (n = 116,192); and the Gallup World Poll for 2015 (n = 1,004), 2016 (n = 1,002), and 2017 (n = 1,001). Household food security status was measured by a shorter version of the Brazilian Food Insecurity Scale, consisting of the first 8 questions of the original 14-item scale. Descriptive and logistic regression analyses were performed to assess the changes in food security and their association with socioeconomic factors. Results suggest that during the crisis the percentage of households classified as food secure declined by one third (76% in 2013 to 49% in 2017) while severe food insecurity tripled (4% in 2013 to 12% in 2017). Whereas before the crisis (2013) 44% of the poorest households were food secure, by 2017 this decreased to 26%. Household income per capita was strongly associated with food security, increasing by six times the chances of being food insecure among the poorest strata. Those who reported a low job climate, social support or level of education were twice as likely to be food insecure. Despite significant improvements between 2004 and 2013, findings indicate that during the crisis Brazil suffered from a great deterioration of food security, highlighting the need for emergency policies to protect and guarantee access to food for the most vulnerable.
本研究旨在描述巴西在最近一次金融危机和政治危机前后的粮食安全状况变化,并探讨危机期间粮食安全与社会经济因素之间的关联。本横断面研究分析了两个不同来源的数据:2004 年(n=112479)、2009 年(n=120910)和 2013 年(n=116192)的巴西全国家庭抽样调查;以及 2015 年(n=1004)、2016 年(n=1002)和 2017 年(n=1001)的盖洛普世界民意调查。家庭粮食安全状况通过巴西粮食不安全量表的简短版本进行衡量,该量表由原始 14 项量表的前 8 个问题组成。进行描述性和逻辑回归分析,以评估粮食安全状况的变化及其与社会经济因素的关联。结果表明,在危机期间,被归类为粮食安全的家庭比例下降了三分之一(2013 年为 76%,2017 年为 49%),而严重粮食不安全的比例则增加了两倍(2013 年为 4%,2017 年为 12%)。在危机前(2013 年),44%的最贫困家庭粮食安全,但到 2017 年,这一比例降至 26%。家庭人均收入与粮食安全密切相关,使最贫困阶层陷入粮食不安全的可能性增加了六倍。那些报告工作环境差、社会支持少或教育水平低的人,陷入粮食不安全的可能性是其他人的两倍。尽管 2004 年至 2013 年期间情况有了显著改善,但调查结果表明,在危机期间,巴西的粮食安全状况严重恶化,突出表明需要采取紧急政策,保护和保障最弱势群体获得粮食。
