Methods:parents from 454 C and 340 AD children followed in reference clinics answered the Children Sleep Habits Questionnaire (CSHQ) that is an one-week retrospective questionnaire composed by 33 questions and divided in 7 subscales (bedtime resistance, sleep duration, sleep anxiety, night awaking, parasomnias, sleep-disordered breathing and daytime sleepness). Total CSHQ scale and subscales were compared between C and DA groups. Spearman’s correlation coefficient between SCORAD (Scoring atopic dermatitis) with all subscales and total CSHQ were also obtained.
Results: C and DA groups were similar regarding age, however, significantly higher values for total CSHQ (62.2±16.1 vs53.3±12.7, respectively) and subscales were observed among DA children in comparison to C, and they were higher among those with moderate (54.8%) or severe (4.3%) AD. Except for sleep duration (r=-0.02, p=0.698), there were a significant Spearman’s correlation index for bedtime resistance (0.24, p<0.0001), sleep anxiety (0.29, p<0.0001), night awaking (0.36, p<0.0001), parasomnias (0.54, p<0.0001), sleep-disordered breathing (0.42, p<0.0001), daytime sleepiness (0.26, p<0.0001) and total CSHQ (0.46, p<0.0001).
Conclusions: although properly treated, Latin-American children with AD showed to have sleep disorders evaluated by the CSHQ. Children with moderate to severe forms of AD were those who had the biggest changes in CSHQ.
