Sleep and quality of life characteristics in a pediatric population with chronic obstructive respiratory diseases

Purpose To describe sleep and quality of life of pediatric patients with chronic obstructive respiratory diseases and to ascertain whether or not sleep quality correlates with quality of life in this population. Methods Participants aged 5 to 18 years with cystic fibrosis (CF), severe asthma, or postinfectious bronchiolitis obliterans (PIBO) receiving regular follow-up at a pediatric respiratory medicine center were recruited. Two questionnaires were used: the Brazilian version of the Sleep Disturbance Scale for Children (SDSC) and the Pediatric Quality of Life Inventory (Peds-QL). Results A total of 46 individuals were included: 30 with CF, 9 with severe asthma, and 7 with PIBO. Almost two-thirds of the patients and their parents or guardians scored at least 39 points on the SDSC, suggesting poor sleep quality. Significantly higher overall median scores were observed in those with severe asthma. Patients and their parents or guardians scored a median of 77 and 80 points respectively on the Peds-QL, with parents of patients with CF scoring higher than any other group. There was a moderate inverse correlation between sleep disorders and quality of life ( r = − 0.532 for patients and r = − 0.606 for parents; p < 0.001). Conclusion Children and adolescents with chronic obstructive respiratory diseases experience impairment in their sleep quality and quality of life. Sleep disorders and quality of life have a moderate negative correlation.
