Sitting still linked to increased risk of depression in adolescents
Too much time sitting still – sedentary behaviour – is linked to an increased risk of depressive symptoms in adolescents, finds a new UCL-led study.
The Lancet Psychiatry study found that an additional 60 minutes of light activity (such as walking or doing chores) daily at age 12 was associated with a 10% reduction in depressive symptoms at age 18.
“Our findings show that young people who are inactive for large proportions of the day throughout adolescence face a greater risk of depression by age 18. We found that it’s not just more intense forms of activity that are good for our mental health, but any degree of physical activity that can reduce the time we spend sitting down is likely to be beneficial,” said the study’s lead author.
