Genetics drive anxiety in young adults.
Genetics explain 60% of persistent anxiety in young adults.
Why it matters
- Genetic basis of anxiety can inform treatments.
By the numbers
- 60% of anxiety stability due to genetics.
- Study included 6,429 twin pairs aged 23-26.
The big picture
- Genetics drive persistent anxiety; environment affects short-term changes.
- Anxiety symptoms cluster into physical distress and worry-avoidance.
What they're saying
- Genetics set baseline; trauma increases anxiety.
- Study may not control for shared twin environments.
Caveats
- Conducted during COVID-19; may affect results.
- Focused on young adults; may not apply to other ages.
What’s next
- More research to separate age and pandemic effects.
- Extend studies to other age groups.
