There is no statistically significant association between ADHD and all variables except for the time spent on computer tablets, which showed that children using computer tablets more than the average time have an increased chance of having ADHD with an odds ratio of 1.9 with 95% confidence interval from 1.08 to 3.40.

This study shows an association between time spent on computer tablets by children and ADHD. There is need for longitudinal studies to demonstrate the temporality and to confirm the association.
