Clinical examinations for TDIs were performed according to the classification proposed by Andreasen. Parents\/caregivers completed a questionnaire addressing sociodemographic characteristics and sleep behaviours\/disorders (sleep duration, insomnia, sleep rhythmic movement, snoring, and signs of sleep apnoea).

Insomnia was observed in 3.0% of the children, snoring in 42.8%, sleep rhythmic movement in 27.9%, and signs of obstructive sleep apnoea in 33.6% of the schoolchildren. Most children (75.2%) slept less than eight hours a day.
