... e logistic regression analysis was used to model the association between breakfast skipping and physical activity while controlling for confounders. Subjects: A total of 936 adolescents aged 12-19 years in the USA. Results: After adjusting for family income, there was no association between breakfast skipping and meeting physical activity guidelines for age among adolescents aged 12-19 years (OR 5 0?95, 95 % CI 0?56, 1?32). Conclusions: Findings from the study differ from previous research findings on breakfast skipping and physical activity. Therefore, further research that uses large, nationally representative US samples and national recommended guidelines for physical activity is needed.
