Helmet Use and Head Injury Part 2.

While analyzing their data, investigators discovered that:

1. Adolescents ages 10-13 were 2.8 times more likely to experience a head injury while skateboarding compared to adolescents ages 14-17, and

2. Adolescents ages 14-17 were 1.5 times more likely to skateboard without a helmet than adolescents ages 10-13.

Given this information, do you think age is a potential confounder of the association between wearing a helmet while skateboarding and suffering a head injury? Describe the three criteria that must be met in order for age to be a confounder, and clearly identify why you think each criterion is or is not met in this specific case.
