Most food industry marketing in products targeted at children is found in packages of foods containing either excessive fat, sugar, or salt. This study audited all 5620 packaged foods available in a store of a large Brazilian supermarket chain and retrieved information from the nutrition facts tables on package labels. Products were photographed for further visual analysis to determine the presence of marketing strategies directed at children. Comparison of nutrient content per 100 g between children's and non-children's food products employed the Student t-test or the Mann-Whitney U-test (-value < 0.05), due to the non-normal distribution of the nutritional composition data as verified through the Shapiro-Wilk test. Brazilian children's food products from groups 4, 5, and 7 presented higher carbohydrate content than similar non-children's products, while children's food products from groups 1 and 7 presented lower fiber content. Results indicate that regulation on food labeling needs revising as it has not been effective in stopping the marketing of energy-dense nutrient-poor foods towards children.
大多数针对儿童的食品行业营销活动都出现在含有过多脂肪、糖或盐的包装食品中。本研究审查了一家大型巴西连锁超市商店中所有 5620 种包装食品，并从包装标签上的营养成分表中检索信息。对产品进行拍照，以便进一步进行视觉分析，以确定针对儿童的营销策略的存在。由于通过 Shapiro-Wilk 检验证实营养成分数据的非正态分布，因此采用学生 t 检验或曼-惠特尼 U 检验（p 值<0.05）比较儿童食品和非儿童食品每 100 克的营养含量。与类似的非儿童产品相比，来自第 4、5 和 7 组的巴西儿童食品产品的碳水化合物含量更高，而来自第 1 和 7 组的儿童食品产品的纤维含量更低。结果表明，食品标签法规需要修订，因为它未能有效阻止向儿童推销高热量、低营养的食品。
