Relationship between Baseline Physical Activity and Generalized Anxiety Disorder and Major Depressive Disorder...

Area of Science:

• Psychiatry
• Clinical Psychology
• Behavioral Medicine

Background:

• Generalized anxiety disorder (GAD) and major depressive disorder (MDD) are common mental health conditions.
• Treatment typically involves medication and psychotherapy.
• The role of lifestyle factors, such as physical activity, in treatment response requires further elucidation.

Purpose of the Study:

• To investigate the correlation between baseline physical activity and treatment response in patients with GAD and MDD.
• To analyze the influence of physical activity on changes in depression and anxiety symptom severity scores.
• To explore potential confounding factors, including caffeine intake, age, sex, and smoking status.

Main Methods:

• Retrospective study of adult patients diagnosed with anxiety and depression.
• Utilized Rapid Assessment of Physical Activity (RAPA) scores to measure baseline exercise.
• Analyzed changes in Patient Health Questionnaire-9 (PHQ-9) for depression and Generalized Anxiety Disorder-7-item scale (GAD-7) for anxiety.
• Statistical analyses were performed to assess correlations.

Main Results:

• No significant difference in treatment response (change in GAD-7 or PHQ-9 scores) was observed based on baseline physical activity levels.
• Caffeine intake demonstrated a direct correlation with improved PHQ-9 scores from baseline to 12-24 weeks.
• Caffeine intake did not show a significant correlation with GAD-7 scores.

Conclusions:

• Pre-treatment physical activity levels do not appear to influence treatment outcomes for anxiety and depression.
• Caffeine intake may be associated with improvements in depression severity, suggesting a potential area for future research.
• Further studies are needed to confirm the role of caffeine in managing depressive symptoms.
