It is possible to verify that not DS children and adolescents urinate in their sleep at night (53.65%), move around a lot while sleeping at night (78.04) and snore at night (53.66%). Table 4 shows the answers referring to sleep habits, with the total number of yes or no answers for each question and between parentheses, according to gender.

The SDSC questionnaire is divided into six factors and summarizes the score of specific questions for each factor: factor 1 (DIMS- questions 1, 2, 3, 4, 5, 10 and 11); factor 2 (SDB--questions 13, 14 and 15); factor 3 (ADD--questions 17, 20 and 21); factor 4 (DSWT--questions 6, 7, 8, 12, 18 and 19); factor 5 (EDS--questions 22, 23, 24, 25 and 26); factor 6 (HS--questions 9 and 16). The total score is the sum of the scores for all questions. The sleep behavior is considered modified when: the DIMS is above 21 points, SDB is above 6 points, ADD is above 11 points, DSWT is above 23 points, EDS is above 19 points and HS is above 7 points. For the child to be considered as having a sleep disorder, the total score must be above 69 points. Table 5 shows each the child score for the SDSC factors. \begin{table}
