Physical activity as prognostic factor for bipolar disorder: An 18-month prospective study

Area of Science:

• Psychiatry
• Clinical Psychology
• Exercise Science

Background:

• Exercise is recognized as an adjuvant therapy for various psychiatric disorders.
• Prospective studies investigating physical activity's role in bipolar disorder (BD) are limited, with inconclusive findings.
• This research addresses the need for clearer evidence on exercise as a prognostic factor in BD.

Purpose of the Study:

• To evaluate physical activity as a prognostic factor in patients with bipolar disorder (BD).
• To analyze the relationship between physical activity levels and key health indicators in BD patients.
• To assess the impact of exercise on anxiety, functionality, sleep, mood episodes, and hospitalizations in BD.

Main Methods:

• 80 outpatients with BD in euthymia were interviewed by three psychiatrists.
• Physical activity intensity was assessed using the International Physical Activity Questionnaire (IPAQ) - short form.
• Patients were monitored for 18 months through monthly reevaluations and medical record reviews to track mood episodes and hospitalizations.

Main Results:

• 47.5% of patients were physically inactive, while 52.5% were active.
• Active patients exhibited lower Body Mass Index (BMI), reduced waist circumference, decreased anxiety levels, and less insomnia.
• Sedentary individuals showed poorer global functioning across multiple domains and a higher incidence of mood episodes and psychiatric hospitalizations over 18 months.

Conclusions:

• Physical activity is suggested as a beneficial prognostic factor for bipolar disorder (BD) during periods of euthymia.
• The findings underscore the importance of promoting exercise within clinical settings for BD management.
• Future research should involve longer-term prospective studies utilizing objective measurement tools to further validate these results.
