INTRODUCTION: Exercise is an adjuvant therapy indicated for various psychiatric disorders. However, prospective studies in patients with bipolar disorder (BD) are scarce and with uncertain conclusions. This study aims to evaluate physical activity as a prognostic factor for BD, analyzing relationship with levels of anxiety, functionality, sleep, mood episodes and hospitalizations. METHODS: Three psychiatrists interviewed 80 BD outpatients in euthymia, referred from four different institutions in Brazil. In this moment, they evaluated the intensity of physical activities using the International Physical Activity Questionnaire (IPAQ) - short form. They reevaluated patients and reviewed medical records monthly for 18 months to identify mood episodes and psychiatric hospitalizations. RESULTS: Thirty-eight patients (47.5%) were physically inactive (or sedentary) and 42 (52.5%) active. Physically active patients had lower Body Mass Index (p = 0.006), waist circumference (p = 0.002), lower levels of anxiety (p = 0.032) and less insomnia (p = 0.001). Sedentary individuals revealed poorer global functioning (p < 0.001) and in all domains: autonomy (p < 0.001), occupational functioning (p = 0.008), cognitive functioning (p = 0.013), capacity of managing the finances (p = 0.012), interpersonal relationships (p = 0.011) and leisure time (p = 0.001). Less activity was associated with more mood episodes (p = 0.042) and psychiatric hospitalizations (p = 0.043) over 18 months. CONCLUSION: This study suggested physical activity as a good prognostic factor for BD during euthymia. This reinforces the need to encourage this practice in clinical settings. Future prospective surveys with longer duration using objective instruments are proposed.
