The purpose of this exploratory, descriptive, and cross-sectional study was to investigate the relationship between the price and availability of food products with and without trans fatty acids in food stores near elementary schools located in low- and medium-income neighborhoods of a Brazilian city. The supply of products containing trans fatty acids was higher in both regions, and these products were also cheaper. It is noteworthy that this availability may influence food choices and, consequently, the health status of children and adolescents, since this population is more likely to buy less-healthy foods when these are more available, accessible, and financially attractive.
这项探索性、描述性横断面研究的目的是调查巴西一个城市中低收入社区的小学附近食品店中含反式脂肪酸和不含反式脂肪酸食品的价格与可获得性之间的关系。两个地区含反式脂肪酸产品的供应量都更高，而且这些产品也更便宜。值得注意的是，这种可获得性可能会影响食物选择，进而影响儿童和青少年的健康状况，因为当这些不太健康的食品更容易获得、更易获取且在经济上更具吸引力时，这一人群更有可能购买它们。
