Walking left fewer depression symptoms than doing nothing
The review found fewer depression and anxiety symptoms with walking than in inactive groups. There was no firm advantage over other interventions.
The key idea
Walking doing better than nothing does not mean it does better than another activity: the answer depended on what it was compared with.
The study, in plain language
Walking can take different forms: programs, duration, and context varied among the trials in this review. The team sought a common answer about depression and anxiety symptoms by comparing walking both with no intervention and with another activity.
On average, symptoms were lower among people who walked than in groups receiving no intervention. When the other group received an active intervention, the difference was no longer firm. Results varied widely across trials, and many had design limitations, so the choice of comparison was central to the answer.
What they found
- On average, people who walked had fewer depression and anxiety symptoms than groups receiving no intervention.
- Compared with groups receiving another active intervention, the difference was not firm.
- Walking programs varied in duration and context, and results differed widely across trials.
Something to think about
When you hear that something improves mood, ask: compared with what? Walking did better than doing nothing, but its advantage over other interventions was not firm.
How they studied it
The team brought together 75 randomized trials with 8,636 participants overall. The adult symptom meta-analysis compared walking with inactive groups or other activities. The trial that included adolescents was excluded from the pooled adult calculations.
What the study cannot show
- Studies differed substantially, and some may have had design problems that affected results. There are also few studies of gentle walking.
- The review does not show that walking replaces clinical treatment or outperforms other activities. Because the studies differed substantially, it also cannot establish an amount of walking that works for everyone.
