Resumen

Background: During the COVID-19 pandemic, adolescents' eating habits have undergone significant changes, with an increase in the consumption of ultra-processed foods. This study aimed to assess the consumption of ultra-processed foods among high school students during the COVID-19 pandemic. Methods: A cross-sectional study was conducted with 135 high school students in Lima, Peru. A self-administered questionnaire was used to measure the frequency of ultra-processed food consumption. Associations between sociodemographic variables and the consumption of ultra-processed foods were evaluated using the chi-square test of independence, considering a significance level of 5%. Results: Permanent consumption of ultra-processed foods was low, below 10% in most categories. Male students showed higher regular and frequent consumption compared to female students, while students in higher grades (4th and 5th grades) and older students (16-17 years) exhibited more consistent consumption. Additionally, Adventist students reported a higher rate of null or sporadic consumption compared to non-Adventists. However, no statistically significant differences were found among the sociodemographic groups evaluated. Conclusions: Although permanent consumption of ultra-processed foods was low, sporadic and regular consumption remains a concern. Educational interventions should focus on reducing the consumption of these products among adolescents, especially those at higher risk.
