A new study shows that worse sleep quality predicts lower physical activity in people with post-traumatic stress disorder (PTSD).
Results show that PTSD was independently associated with worse sleep quality at baseline, and participants with current PTSD at baseline had lower physical activity one year later.
Further analysis found that sleep quality completely mediated the relationship between baseline PTSD status and physical activity at the one-year follow-up, providing preliminary evidence that the association of reduced sleep quality with reduced physical activity could comprise a behavioral link to negative health outcomes such as obesity.
