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 identifed in line with the NOVA system of food classifcation. 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 fbers. 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 profle of the diet and contributes to negative changes in the lipid parameters of young individuals.

Estudo transversal realizado com adolescentes de ensino médio. O consumo alimentar foi analisado por meio de recordatório alimentar de 24h, sendo os AUP identifcados de acordo com a NOVA classifcação de alimentos. Os níveis de colesterol total, HDL-c e triglicérides, foram determinados por colorimetria enzimática e a fração de LDL-c estimada por fórmula. Utilizou-se o teste t de Student ou Mann-Whitney para comparação de médias e regressão linear para realizar associações entre as variáveis. Os resultados mostram que o consumo de AUP foi mais frequente nas adolescentes do sexo feminino, entre a faixa etária 17 a 19 anos, com renda familiar superior a dois salários mínimos e de escolas particulares. Nota-se que os indivíduos no maior tercil de consumo de AUP apresentaram maior ingestão energética, de carboidratos e de sódio, com menor ingestão de proteínas e de fbras. Observouse, ainda, que o maior consumo de AUP foi associado negativamente aos níveis de HDL-c e positivamente aos níveis de trigli
