In a study of 5,515 early adolescents in the United States, those who took more steps each day had lower measured mental health problem scores one year later. The finding is an association, not proof that walking more improves mental health or a prescription for a particular daily step target.
What did the study find?
The study, “Physical Activity and Adolescent Brain Structure, Mental Health, and Academic Outcomes,” was published in JAMA Network Open on October 1, 2026. Researchers analyzed data from the US Adolescent Brain Cognitive Development (ABCD) Study. The participants had a mean age of 11.93 years, and 47.9% were female. Their average daily steps were measured with pedometers over the preceding three weeks; mental health and academic outcomes were assessed one year later. Read the study in JAMA Network Open.
Participants averaged 9,595 steps per day, with a standard deviation of 3,239. Higher step counts were associated with lower total mental health problem scores a year later (B = −0.080, SE = 0.015; 95% CI, −0.109 to −0.052; P < .001). The researchers also found progressively lower Brief Problem Monitor scores across higher step-count categories compared with the group averaging fewer than 5,000 steps a day.
King’s College London’s summary describes the pattern using groups below 5,000 steps, around 8,000, and at least 12,000 steps daily. The researchers did not observe a plateau within the range measured. These bands describe the study’s observed pattern; they are not proven thresholds or goals for every adolescent.

Does taking more steps cause better mental health?
The study cannot establish that. It was an observational cohort analysis, not a randomized trial assigning young people to walk different amounts. Although step counts were measured before the later mental health assessment, other factors may help explain the association. For example, adolescents experiencing fewer problems may already have been more active. The university’s summary explicitly notes this possibility.
The outcome was a measured mental health problem score. The result does not show that steps prevent, diagnose, or treat a mental disorder, and the study did not establish a clinical step target. Its participants came from the US ABCD Study and had available step-count and neuroimaging data, so the findings should not automatically be generalized to every population.

- 🎁[Kids Sport Watches] Fitness Tracker — No Need to Connect Phone, you don’t download any APP, just bring a watch to track smartly, step counting, stopwatch, calories, mileage, and recording of every day’s exercise data. The pedometer calculates the number of steps by swinging the arm. When the arm swings frequently, it may cause the step data to be higher than the actual number of steps. The number of steps will automatically return to zero at 0:00 every day.

What did the researchers find about the brain?
Higher step counts were associated with greater cortical thickness in two regions: the paracentral region (B = 0.057, SE = 0.016; P < .001) and the rostral anterior cingulate region (B = 0.052, SE = 0.016; P = .001). A statistical mediation analysis found that paracentral thickness accounted for part of the association between step count and later mental health problem scores (indirect effect B = −0.002, SE = 0.001; 95% CI, −0.0045 to −0.0004; P = .02).
Statistical mediation does not prove that brain changes caused the mental health association. The findings identify a relationship in the data, not a confirmed biological pathway.

Did higher step counts relate to academic performance?
No association between step count and academic performance was found in the study’s main analysis of outcomes one year later. The reported result therefore concerns mental health problem scores, not a demonstrated academic benefit.

The study supports the idea that everyday movement is worth exploring as one accessible part of adolescent life, but it does not specify how much a young person should walk. King’s College London’s summary quotes co-author Amanda Paluch emphasizing realistic, sustainable movement through activities such as walking to school, active play, or activities a young person enjoys. Those are practical examples, not interventions compared in the study.

- Choose movement that fits the adolescent’s interests, circumstances, and abilities rather than treating a study category as a required target.
- A pedometer or other step counter can help measure steps, but this study did not test whether consumer trackers improve mental health or recommend a device.
- Do not use a step count as a substitute for professional evaluation or care when a young person is struggling.
The highest step-count range was sparsely represented, so the researchers could not establish whether the observed pattern continues beyond the range well represented in the sample. The study was funded by the Brain & Behavior Research Foundation, UK Research and Innovation Medical Research Council, and the Canadian Institute for Advanced Research Global Scholars Program, according to King’s College London.
