Abstract

Objective The aim of the study was to investigate the prevalence of difficulty with initiation or maintenance of sleep (DIMS) and excessive daytime sleepiness (EDS) in a general pediatric population, and to evaluate the relationship between these conditions and sleep-disordered breathing (SDB) symptom intensity. Methods This population-based cross-sectional study from 27 primary schools in a medium-sized city in Poland was based on use of a questionnaire regarding demographic data, symptoms of SDB, DIMS, and EDS. Data were collected between September and December 2014. In all, 2940 caregivers were recruited and were asked to fill-out questionnaires and written consent. Results A total of 68% of the questionnaires (n = 1987) were returned and analyzed. Habitual snoring (HS) was reported in 104 (5.3%) children. DIMS and EDS were seen in 137 children (6.9%) and 117 children (5.9%), respectively. The prevalence of DIMS increased from 3.5% in children who never snored to 28.6% in children who snored very often or always. Similarly, the prevalence of EDS was 2.7% in children who did not snore and increased to 19% in children who snored very often or always. No correlation was seen between increasing DIMS (r = 0.006, p > 0.05) or EDS (r = −0.031, p > 0.05) scores and body mass index. Conclusions This study is the first to measure the symptoms of both DIMS and EDS in a general pediatric population and to assess the relationship between both DIMS and EDS and SDB in children. We found that children with more frequent snoring had a higher prevalence of DIMS as well as EDS; however, there was no correlation between body mass index and either DIMS or EDS symptom severity.
