Adherence
The combination of high physical activity (≥90 minutes/day) and low television watching (0-5 hours/week) results in the strongest reduction in clinical depression risk compared to the combination of low activity and high TV watching.
For the best protection against depression, aim for 90 minutes of daily physical activity and limit television watching to 5 hours or less per week. This combination offers the strongest benefit, reducing risk by 38% compared to those with low activity and high TV time. Start by adding 30 minutes of walking to your day and tracking your TV time to see if you can reduce it.
In fully adjusted analyses of the joint influence of television watching and PA on cases who reported both depression diagnosis and use of antidepressants, those who were the most active (≥90 minutes/day) and spent the least amount of time watching television (0–5 hours/week) had the strongest significant inverse association with depression (relative risk = 0.62, 95% CI: 0.48, 0.79).
Why this rating
Large cohort, long follow-up, joint analysis provides robust evidence for the combined effect.
