The omission of breakfast has a rate of up to 74.70% among children and adolescents, occurring mainly among adolescents. As breakfast is one of the main meals of the day, skipping it can negatively affect the nutritional status of this group. The habit of skipping breakfast among adolescents is associated with a higher percentage of body fat, a larger waist circumference, obesity and overweight. These are risk factors for various diseases, especially chronic non- communicable diseases. The aim of this study was to estimate the effects of skipping breakfast on the nutritional status of adolescents from the São Luís, Maranhão birth cohort. This is a cross-sectional study with data from 2,515 adolescents aged between 18 and 19 born in the city of São Luís. Information was collected on demographic and economic characteristics, lifestyle habits, morbidity, body composition and dietary intake. Breakfast consumption was assessed using a food frequency questionnaire. Nutritional status was assessed using the BM/height indicator and body fat percentage. A theoretical model was developed based on a directed acyclic graph to establish the minimum adjustment sets needed to estimate the causal effects. Structural equation modeling was used to analyze the association between skipping breakfast and nutritional status. The omission of breakfast in the study was 15.00%. Most of the adolescents were classified as eutrophic (73.62%), were sedentary (44.88%) and had a body fat percentage classified as normal (72.49%). Among the adolescents with a high percentage of body fat, 41.04% had normal weight obesity and the majority of adolescents, both those with adequate nutritional status and those who were overweight, had high levels of triglycerides (66.86% and 31.37% respectively). Skipping breakfast had no effect on nutritional status (PC: 0.120; p = 0.075). Even though the rate of skipping breakfast was lower than that reported in other studies, this rate is still a cause for concern. Further research is needed to assess the impact of skipping breakfast on adolescents' eating habits and physical activity. Future studies are essential to support effective health policies and promote healthy development and disease prevention.
