Adolescents have heterogeneous health problems; Currently, the presence of risky eating behaviors CAR (for its acronym in Spanish) and unhealthy lifestyles in young people has increased, contributing to the figures of overweight, obesity and problems such as eating disorders and food ingestion. Objective. Determine the relationship between risky eating behaviors, lifestyle and resilience level of upper secondary education students from public institutions in the municipality of Santiago de Querétaro. Methodology. It was a cross-sectional and analytical study, where 385 adolescents enrolled in public schools of 14-19 years, both sexes, were included. Weight, height was measured and the body mass index for age was calculated. A battery of instruments was applied to measure the variables risk eating behaviors, lifestyle, and level of resilience. Descriptive statistics were used for data analysis. The relationship of the study variables was determined with the X2 test. Results: The findings show that 23.4% of adolescents were overweight (men 23.5%; women 23.2%) while 9.4% were obese (men 8.0%; women 10.6%). Risk eating behaviors are related to the level of resilience regarding the dimensions, social competence (X2 = 13.03) and personal competence (X2 = 9.86), as well as with the lifestyle in the feeding dimensions (X2 = 8.64) , drug use (X2 = 7.09), sleep (X2 = 5.91) and self-perceived emotional state (X2 = 8.51). Conclusions A low and medium level of resilience in dimensions of social competence and personal competence is related to the adoption of CAR. Adolescents who presented CAR tend to carry out unhealthy lifestyle practices in dimensions of diet, drug use, sleep, and self-perceived emotional state.
