The scope of this study was to analyze the association between ultra-processed food (UPF) consumption and lipid parameters. It was a cross-sectional study performed with high school adolescents. Food consumption was analyzed by means of a 24-hour food recall form, where UPF were identified in line with the NOVA system of food classification. The total cholesterol levels, HDL-c and triglycerides were determined by enzymatic colorimetry and the LDL-c fraction estimated by formula. The Student's t-test or Mann-Whitney was used to compare averages, and linear regression to make associations among the variables. The results show that UPF consumption was more frequent in female adolescents between 17 and 19 years of age, with a family income above two minimum wages and from private schools. It was observed that individuals in the upper third of UPF consumption had a higher energetic, carbohydrate and sodium intake, with a lower intake of proteins and fibers. Moreover, it was found that a higher UPF intake was negatively associated with HDL-c levels and positively associated with triglyceride levels and dyslipidemia. Therefore, UPF is associated with a worsening of the nutritional profile of the diet and contributes to negative changes in the lipid parameters of young individuals.
本研究的范围是分析超加工食品（UPF）消费与血脂参数之间的关联。这是一项针对高中青少年开展的横断面研究。通过24小时食物回忆表分析食物消费情况，其中根据NOVA食物分类系统确定超加工食品。采用酶比色法测定总胆固醇水平、高密度脂蛋白胆固醇（HDL-c）和甘油三酯，并通过公式估算低密度脂蛋白胆固醇（LDL-c）分数。使用学生t检验或曼-惠特尼检验比较平均值，并采用线性回归分析变量之间的关联。结果显示，17至19岁、家庭收入高于两份最低工资且来自私立学校的女性青少年更频繁食用超加工食品。据观察，超加工食品消费量处于上三分位的个体能量、碳水化合物和钠摄入量较高，而蛋白质和纤维摄入量较低。此外，研究发现，较高的超加工食品摄入量与高密度脂蛋白胆固醇水平呈负相关，与甘油三酯水平和血脂异常呈正相关。因此，超加工食品与饮食营养状况恶化有关，并导致年轻人血脂参数出现负面变化。
