Attention-Deficit/Hyperactivity Disorder Traits in Childhood and Physical Health in Midlife

Area of Science:

• Neuroscience
• Public Health
• Epidemiology

Background:

• Attention-deficit/hyperactivity disorder (ADHD) is linked to health risks, but long-term physical health outcomes are understudied.
• Research has primarily focused on childhood and young adulthood, leaving a gap in understanding midlife health trajectories for individuals with ADHD traits.

Purpose of the Study:

• To examine the association between childhood ADHD traits and physical health in midlife.
• To investigate the role of health risk factors in mediating this association.

Main Methods:

• Utilized data from the 1970 British Cohort Study, a nationally representative sample.
• Assessed ADHD traits at age 10 and physical health outcomes (conditions, multimorbidity, disability) at age 46.
• Employed Cox proportional hazards models and path analyses to explore associations and mediating factors like smoking and BMI.

Main Results:

• Higher childhood ADHD traits correlated with more physical health conditions, increased odds of multimorbidity, and greater physical disability by age 46.
• Associations were partly explained by indirect pathways through smoking, psychological distress, and body mass index.
• A notable sex difference was observed for physical disability, with a larger effect size in women.

Conclusions:

• Childhood ADHD traits predict poorer midlife physical health, with health risk factors playing a significant mediating role.
• Addressing modifiable risk factors is crucial for mitigating long-term health disparities in individuals with ADHD.
• Lifelong interventions are necessary to promote the health and well-being of people with ADHD.
