Methods: parents from 454 C and 700 A and/or AR 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 sleepiness). Total CSHQ scale and subscales were compared between C and A+AR, A (n=285) vs AR (n=390), and controlled A (CA, n=103) vs partially controlled/uncontrolled A (UA, n=182).
Results: comparison between C and A+AR showed no significant differences in age (6.7 vs 7.0 years, respectively) and total CSHQ (53.3 vs 63.2, respectively) and subscales were significantly higher among A+AR group. Comparison between A and AR groups, except for sleep anxiety, show significantly higher values for total CSHQ (66.9 vs 61.0, respectively) and the other subscales. UA showed significantly higher values for total CSHQ and subscales in comparison to CA (71.1 vs 59.4, respectively).
Conclusions: Latin-American asthmatic and/or allergic rhinitis children showed to have sleep disorders defined by the CSHQ when compared to normal controls. Despite being treated, asthma causes sleep compromise, mainly if uncontrolled.
