Moderate-to-Vigorous Physical Activity and Suicidal Ideation in Adolescents with Attention Deficit/Hyperactivity Disorder: the Mediating Effects of Mental Health.
Daily MVPA can lower suicidal thoughts in teens with ADHD by easing depression.
01Research in Context
What this study did
Researchers asked 327 teens with ADHD to wear a wrist tracker for one week.
The tracker counted minutes of moderate-to-vigorous physical activity (MVPA).
Each teen also filled out surveys on suicidal thoughts, depression, anxiety, and resilience.
What they found
Teens who moved more had fewer suicidal thoughts.
Depression explained the whole link: MVPA lowered depression, and lower depression cut suicidal thoughts.
Anxiety and resilience added extra small steps in the chain, but depression was the main bridge.
How this fits with other research
Chueh et al. (2021) saw the same benefit in younger kids after a single 50-minute exercise bout.
Wang et al. (2024) extended the idea by showing that 12 weeks of activity improved sleep and thinking skills in elementary children with ADHD.
Liang et al. (2018) found a different path: 90 days of methylphenidate also cut suicide risk.
Together, these studies say both pills and movement can protect ADHD youths, but MVPA is a pill-free option you can add today.
Why it matters
If a teen with ADHD shows signs of depression, build in 15–20 minutes of brisk walking, biking, or dancing each day.
Track mood before and after for two weeks.
Small daily movement may quietly lower suicide risk while you work on other goals.

03Original abstract
This study aimed to (a) examine whether device-assessed moderate-to-vigorous physical activity (MVPA) was associated with suicidal ideation (SI) in adolescents with attention-deficit/hyperactivity disorders (ADHD), (b) investigate whether the association was mediated by depression, and (c) assess whether anxiety, stress, and resilience would work with depression to constitute chain mediation paths between MVPA and SI. Sixty adolescents with ADHD aged 12-17 (Mage = 14.33 ± 1.43 years) met the inclusion criteria. MVPA data were assessed using accelerometers worn around the waist for seven consecutive days. SI, depression, anxiety, stress, and resilience were examined using self-report questionnaires. Bivariate correlations were estimated for all variables. Lavaan package was used to examine the association between MVPA and SI, and the mediating effects of depression, anxiety, stress, and resilience by adjusting for a minimally sufficient confounder set and applying the bootstrap method. MVPA was negatively associated with SI. Depression fully mediated this association. Anxiety, stress, and resilience combining with depression formed three chain mediation paths between MVPA and SI, respectively. The integrative mediation model, including anxiety, stress, resilience, and depression, revealed that anxiety and depression explained 38.2% of the variance in the association between MVPA and SI, and resilience and depression explained 22.1%, while stress did not. MVPA could serve as an alternative or adjunctive approach, particularly in conjunction with depression-focused interventions, to increase resilience, decrease anxiety and depression, and in turn to prevent or attenuate SI in adolescents with ADHD.
