Study: ADHD Traits in Childhood May Predict Poor Physical Health Later

February 23, 2026

ADHD traits in childhood predict physical health problems in midlife, but early exercise interventions may offset this risk, suggest two new studies.

A cohort study of 10,930 participants published in JAMA found that adults with severe childhood ADHD traits had more physical health problems and greater physical health-related disability by age 46 compared to those with less severe ADHD symptoms by age 10.¹

The researchers reported that 42.1% of participants with higher ADHD traits in childhood developed multimorbidity (two or more co-occurring physical health conditions) by age 46. In comparison, just 37.5% of participants with fewer ADHD traits experienced the same health outcomes. Notably, the link between ADHD traits and physical health-related disability appeared much larger in women than it did in men.

Cumulative exposure to health risk factors, such as smoking, alcohol use, psychological distress, low educational attainment, and high body mass index, explains part of the association between ADHD, multimorbidity, and physical disability. However, the researchers emphasized that the direct association between ADHD and physical health outcomes remained significant.

“Clinicians should be aware of the increased rates of physical health problems and associated disability in people with ADHD and should proactively address potential contributing health risk factors,” they wrote. “Integrated interventions addressing mental health, physical health, and key health risk factors may help to reduce chronic conditions in this population.”

The JAMA study analyzed data from the population-based 1970 British Cohort Study, which included people born in England, Scotland, and Wales during the same week in 1970, with follow-up data collected over 46 years.

Increased Mortality Risk for People with ADHD

Untreated physical health problems and co-occurring conditions could reduce the life expectancy of people with ADHD at a higher rate than seen in the general population. A January 2025 study published in The British Journal of Psychiatry comparing the mortality rates of people diagnosed with ADHD to people without ADHD found that the life expectancy for women with ADHD is 8.6 years shorter than that of women without ADHD, while the life expectancy of men with ADHD is 6.8 years shorter. ²

“Adults with diagnosed ADHD are living shorter lives than they should,” the study’s authors wrote. “We believe that is likely caused by modifiable risk factors and unmet support and treatment needs in terms of both ADHD and co-occurring mental and physical health conditions.”

Exercise Interventions Improve Long-Term Mental Health

A 2023 treatment survey of 11,000 ADDitude readers reported positive benefits of exercise. About half of the respondents who exercise regularly rate this ADHD treatment as “extremely” or “very” effective. A staggering 94% of caregivers and 95% of adults recommend exercise to treat ADHD symptoms. However, only 13% said a doctor had recommended exercise to reduce symptoms, and just 37% said physical activity was part of their treatment plan.

“When I get into a good stride with routine exercise, it almost always goes hand-in-hand with better eating habits, better focus, energy levels, mental clarity, and stronger relationships and productivity,” said one adult with ADHD. “Exercise is undoubtedly a crucial piece of the (treatment) puzzle.”

“Depression can really take hold of my 10-year-old son,” one parent said. “We see great improvements after physical activity. He enjoys the elliptical, rower, spin bikes, automatic stepper, and treadmill.”

A new meta-analysis including 18 studies further explores the potential of exercise as an effective adjunctive approach for improving mental health in individuals with ADHD when it is integrated into a multimodal treatment plan that includes pharmacotherapy, behavioral therapy, or psychoeducation.
Exercise interventions produced small-to-moderate improvements in depressive symptoms, anxiety, and emotion regulation in individuals with ADHD, according to the study published in Frontiers in Psychology.

Mind-body integrated exercises, such as yoga and tai chi, significantly improved both depression and anxiety symptoms compared to physical exercises (e.g., structured fitness or sports without a mindfulness component), which did not show significant improvements across outcomes.

The researchers suggest that this advantage may stem from the “mind-body integration” of activities like yoga. By combining physical movement with breath awareness, focused attention, and present-moment acceptance, mind-body exercises directly target emotional dysregulation and attentional control, which are core components of ADHD.

Results from the meta-analysis found that adolescents with anxiety who practiced mind-body exercises experienced the greatest improvements. While children showed moderate improvement, the results were not statistically significant. These discrepancies could be due to developmental differences: Adolescents may be better able to engage with and benefit from the psychological components of exercise, while younger children may require more play-based or gamified approaches.

In addition, the most statistically significant reduction in depressive symptoms occurred from moderate-intensity exercise, whereas low-intensity and high-intensity exercises did not demonstrate measurable benefits for depression, anxiety, or emotion regulation.

While intervention length varied widely (from single sessions to 20-week programs), with no clear differences emerging across durations, single sessions demonstrated immediate short-term anxiety-reducing effects. However, to sustain benefits, longer-term participation may be necessary, the researchers suggest.

They emphasized that the study’s overall findings should be viewed as hypothesis-generating rather than definitive. “Because study designs and exercise protocols varied considerably, the results should be interpreted cautiously, and more rigorous research is needed before definitive clinical guidelines can be established,” they wrote.
