Evidence of sleep duration and weekend sleep recovery impact on suicidal ideation in adolescents with allergic rhinitis

Study Objectives: Sleep problems are common in allergic rhinitis (AR) and are a modifiable risk factor for suicidal ideation. However, the effect of sleep duration and weekend catch-up sleep (WCUS)-sleep time on weekends that exceeds sleep time on weekdays-on suicidal ideation for adolescents with AR is unknown. The objective of this study was to explore whether sleep duration and WCUS have an impact on suicidal ideation among adolescents with AR. Methods: From the annual Korean Youth Risk Behavior Web-Based Surveys (completed from 2013-2017), data were obtained from a stratified, multistage, clustered sample. Using self-reported questionnaires, students provided doctor-diagnosed AR and sleep time. Results: Among 134,417 and 262,653 adolescents with and without AR, respectively, those with AR compared with those without AR had more sleep dissatisfaction (46.6% vs 40.8%), slept less (sleep duration: 6.71 +/- 1.37 hours vs 7.01 +/- 1.48 hours), and had longer WCUS (3.46 +/- 0.11 hours vs 2.11 +/- 0.14 hours). After adjustment, the odds ratio of patients with sleep dissatisfaction was a 1.22 (95% confidence interval, 1.17-1.28) times higher risk of suicidal ideation than in those with sleep satisfaction. For average sleep duration (defining 7-8 hours as the reference), the odds ratio of short sleep (<= 5 hours) was 1.45 (95% confidence interval, 1.32-1.53). Notably, long WCUS (>= 2 hours) was significantly associated with decreased suicidal ideation (odds ratio, 0.85; 95% confidence interval, 0.81-0.92). Conclusions: Although further research is needed clarify this association, under the condition of sleep deprivation, WCUS at a certain extent may be associated with a low risk for suicidal ideation in adolescents with AR.
