To critically review studies evaluating the impact of Bolsa Família (PBF), a federal cash transfer program, for food and nutrition security in Brazil.
The Cochrane Library, LILACS, Medline and SciELO databases were searched, as well as public organization websites. All studies based on primary data were selected. The following were excluded: studies using secondary data, review articles, studies that did now allow the establishment of associations between PBF and food and nutrition security, as well as studies evaluating food security strictly in sanitary terms.
Ten studies were included. Of these, five concluded that PBF had a positive impact on the food and nutrition security of participating families. Three studies observed an increase in the consumption of foods with higher calorie content and less nutritional value. This change in dietary habits is a risk factor for the development of overweight, obesity, and noncommunicable chronic diseases.
The guarantee of food and nutrition security requires programs that focus on both malnutrition and overweight and obesity. Cash transfer programs such as the PBF can contribute more effectively to the nutritional well-being of participants if they are combined with other types of interventions, such as actions to promote healthy eating.
严格审查评估巴西一项联邦现金转移支付计划“家庭补助金”(Bolsa Família,PBF)对粮食和营养安全影响的研究。
检索了考克兰图书馆、拉丁美洲及加勒比卫生科学数据库(LILACS)、医学索引数据库(Medline)和科学电子图书馆在线数据库(SciELO)以及公共组织网站。选取了所有基于原始数据的研究。排除以下研究:使用二手数据的研究、综述文章、无法确定PBF与粮食和营养安全之间关联的研究,以及严格从卫生角度评估粮食安全的研究。
纳入了10项研究。其中5项得出结论,PBF对参与家庭的粮食和营养安全有积极影响。3项研究观察到高热量和低营养价值食品的消费量增加。这种饮食习惯的变化是超重、肥胖和非传染性慢性病发展的风险因素。
保障粮食和营养安全需要关注营养不良以及超重和肥胖问题的项目。像PBF这样的现金转移支付计划如果与其他类型的干预措施(如促进健康饮食的行动)相结合,就能更有效地促进参与者的营养福祉。
