Aims: Regarding the low level of physical activity (PA) in schizophrenia and bipolar disorder (BD), our aim was to compare the level of PA
between the two groups. Methods: In this cross‑sectional study, 100 patients with schizophrenia and 100 patients with BD were selected
through convenience sampling in 2017. The level of PA was assessed using International Physical Activity Questionnaire. Chi‑square,
extended Fisher’s exact, Student’s t, and Mann–Whitney tests were applied to analyze the data. Results: Prevalence of low PA in schizophrenic
patients and BD was 36.7% and 30.3%, respectively. The frequency of moderate PA was less in schizophrenic patients than that in the BD
patients (56.1% and 65.7%, respectively) and vigorous PA was more frequent in schizophrenic patients than the BD individuals (7.1% and
4%, respectively) (P = 0.334). Schizophrenic patients had significantly fewer minutes of PA than that of the BD patients (P = 0.027). Minutes
of vigorous PA were higher in schizophrenic patients, while BD patients had more minutes of moderate PA, but these differences were not
statistically significant (P > 0.05). BD patients had significantly more walking minutes than that of the schizophrenic patients (P = 0.05).
Conclusion: The prevalence of inactivity was higher in schizophrenic patients than BD patients. This rate was high in both groups due to
hospitalization, factors associated with the disease, or even lack of attention to these patients. Therefore, more attention should be paid to the
physical health of these patients; also, psychiatric centers should take preventive and interventional measures in this regard.
