The objective of this study was to investigate the association between movement behaviors, sleep quality, and anxiety symptoms in adolescents. This cross-sectional study included 250 Brazilian school adolescents (aged 16.6 ± 1.2 years) from a federal public school. Moderate-to-vigorous physical activity (MVPA; classified as physically active ≥60 min/day and physically inactive [p p = .021). Participants with poor sleep quality had a higher prevalence of anxiety compared with those with good sleep quality (PR = 1.47, 95% CI: 1.16, 1.88; p = .002). SB was not associated with anxiety (p > .05). In conclusion, the results suggest that physically inactive adolescents and those with poor sleep quality have a higher prevalence of anxiety symptoms. Moreover, specific combinations of physical inactivity, high SB, and poor sleep quality, as well as the concomitant presence of all three, are associated with an even greater prevalence of anxiety symptoms.
