To analyse changes and predictors of change in self-reported food intake among Brazilian families that benefitted from conditional cash transfer (CCT) implemented in the Programa Bolsa Família of the Brazilian Federal Government.
A cross-sectional survey.
The study was conducted from September to October 2007 in a nationwide representative household sample of families included in the CCT. Socio-economic variables, perception of food consumption and food insecurity were evaluated via questionnaire, which was completed during face-to-face interviews.
Five thousand households were selected from the CCT registry.
Families reported increased consumption of all food groups analysed, mainly cereals, processed foods, meat, milk and dairy, beans and sugar. The degree of dependence on income from the CCT was positively associated with increased self-reported intake of food items such as sugar and soft drinks. A Poisson regression revealed that the fourth quartile of CCT dependence demonstrated a twofold increase in the self-reported intake of soft drinks (relative risk (RR) = 2·3, 95% CI 1·8, 2·9) and sugar (RR = 2·5, 95% CI 2·1, 3·1) compared with the first quartile of CCT dependence.
Greater purchasing power of poor families increases unhealthy food choices; thus public policies should emphasise the availability of healthy food.
分析受益于巴西联邦政府实施的“家庭强化救助计划”(Bolsa Família)的巴西家庭中自我报告的食物摄入量的变化及其变化的预测因素。
横断面调查。
该研究于 2007 年 9 月至 10 月在全国范围内具有代表性的家庭样本中进行,这些家庭均受益于该计划。通过问卷调查评估了社会经济变量、食物消费感知和食物不安全情况,问卷调查是通过面对面访谈完成的。
从“家庭强化救助计划”登记册中选择了 5000 户家庭。
家庭报告称,所有分析的食物组的摄入量均有所增加,主要是谷物、加工食品、肉类、牛奶和奶制品、豆类和糖。对来自“家庭强化救助计划”的收入的依赖程度与自我报告的糖和软饮料等食物摄入量的增加呈正相关。泊松回归显示,与“家庭强化救助计划”依赖程度的第一四分位数相比,第四四分位数的家庭报告称软饮料(相对风险(RR)=2·3,95%可信区间(CI)1·8, 2·9)和糖(RR=2·5,95%CI 2·1, 3·1)的自我报告摄入量增加了一倍。
贫困家庭的购买力增强会增加不健康的食物选择;因此,公共政策应强调健康食品的供应。
