This study aimed to analyze the relationship between food insecurity and school meal consumption, adjusted for sociodemographic variables.
This cross-sectional study investigated households with children and adolescents living in Brazilian municipalities. A semistructured survey was administered to parents/guardians at a parent-teacher meeting to assess their socioeconomic conditions and access to food, using the Brazilian Food Insecurity Scale to classify households as having food security or mild, moderate, or severe food insecurity. Parents and students were asked about the frequency of their consumption of school meals offered by the Brazilian School Food Program, which is one of the largest public policies in Brazil and offers free meals to all students in all public schools. Multinomial regression was performed to assess the relationship between food security and frequency of school meal consumption.
A total of 1705 students participated in the study, most of whom displayed some degree of food insecurity (56.5%) per the Brazilian Food Insecurity Scale. Regular consumption of school meals (>3 times/wk) was reported by 78.5% of students. Regarding the frequency of school meal consumption adjusted by sociodemographic variables, students from households with food insecurity (moderate or severe) were more likely to regularly consume school meals. The prevalence of households with moderate or severe food insecurity was twice as high as for those who lived in households with food security after adjusting for sociodemographic variables (odds ratio: 2.35; 95% confidence interval 1.53-3.61).
The Brazilian School Food Program has contributed greatly to food security. Although the guarantee of universality is essential for the program to reach all school children who are experiencing food insecurity, the program should also aim for greater equity.
本研究旨在分析食物不安全与学校供餐消费之间的关系,并对社会人口学变量进行调整。
本横断面研究调查了巴西各城市中存在儿童和青少年的家庭。在家长教师会议上,通过半结构式调查向家长/监护人询问其社会经济状况和食物获取情况,使用巴西食物不安全量表将家庭分为食物安全、轻度、中度或重度食物不安全。询问家长和学生巴西学校供餐计划中学校供餐的消费频率,该计划是巴西最大的公共政策之一,为所有公立学校的所有学生提供免费餐食。采用多项回归分析评估食物安全与学校供餐消费频率之间的关系。
共有 1705 名学生参与了研究,根据巴西食物不安全量表,大多数学生存在某种程度的食物不安全(56.5%)。78.5%的学生经常食用学校供餐(>3 次/周)。在校餐消费频率的调整中,中度或重度食物不安全家庭的学生更有可能经常食用学校供餐。调整社会人口学变量后,中度或重度食物不安全家庭的比例是食物安全家庭的两倍(比值比:2.35;95%置信区间 1.53-3.61)。
巴西学校供餐计划极大地促进了食物安全。虽然普遍性保障对于该计划来说至关重要,因为它旨在惠及所有经历食物不安全的在校儿童,但该计划也应追求更大的公平性。
