Abstract

Objectives: The association between ultra-processed foods (UPF) consumption and cognitive performance needs to be better characterized in adolescents, especially in low-income settings, where the cost of human capital is high. This study investigated the association between cognitive performance and UPF in adolescents from the countryside of the Brazilian Northeast.

Methods: Adolescents (15-18 years old) from three public high schools were included. Food intake was assessed using three 24-hour dietary recalls. The classification of foods as UPF was determined according to the Nova classification. Cognitive performance was evaluated using the Non-Verbal General Intelligence Test.

Results: 116 adolescents were included, of which 50 (43.1%) showed low cognitive performance. The average energy intake was 1973.5 kcal, with 24.2% coming from UPF. Participants with low cognitive performance consumed 26.5% (95% CI: [22.2; 30.7]%) of daily energy intake from UPF compared to 22.5% ([18.8; 26.2]%) of those with medium-high cognitive performance (P = 0.17), without differences in energy and macronutrient intake.

Conclusion: Despite similar UPF consumption compared to the Brazilian average, no association was found between UPF consumption and cognitive performance in this low-income adolescent sample.

巴西欠发达城市青少年学生超加工食品摄入量与认知能力之间的关系：一项横断面研究

研究目的需要更好地了解青少年食用超加工食品（UPF）与认知能力之间的关系，尤其是在人力资本成本较高的低收入环境中。本研究调查了巴西东北部农村青少年的认知能力与超加工食品之间的关系：研究对象包括来自三所公立高中的青少年（15-18 岁）。食物摄入量通过三次 24 小时饮食回忆进行评估。根据诺瓦分类法确定食物的 UPF 分类。认知能力采用非言语综合智力测验进行评估：结果：共纳入 116 名青少年，其中 50 人（43.1%）认知能力低下。平均能量摄入量为 1973.5 千卡，其中 24.2% 来自 UPF。认知能力低的参与者每天摄入的能量中有26.5%（95% CI：[22.2；30.7]%）来自UPF，而认知能力中等偏上的参与者每天摄入的能量中有22.5%（[18.8；26.2]%）来自UPF（P = 0.17），两者在能量和宏量营养素摄入方面没有差异：结论：尽管UPF摄入量与巴西的平均水平相近，但在这一低收入青少年样本中，UPF摄入量与认知能力之间没有关联。
