Association of Sleep Duration and Weekend Catch-Up Sleep with Suicidal Ideation Among Adolescents with Asthma: Secondary Data Analysis Based on a Nationwide Cross-Sectional Study

Abstract

Background: Sleep problems are common in asthma. We explored whether sleep duration and weekend catch-up sleep (WCUS), sleep time on weekends that exceeds sleep time on weekdays, are associated with suicidal ideation among adolescents with asthma. Methods: Data were acquired from adolescents participating in the 2019 Korean Youth Risk Behavior Web-based Surveys (KYRBS), which was self-administered, online survey. The KYRBS data were obtained from a stratified, multistage, clustered sample. Students responded prior diagnoses of asthma and sleep time. Associated factors for suicidal ideation were tested by logistic regression models.Results: Among 3,579 and 48,072 adolescents with and without asthma, respectively, adolescents with asthma were younger (14.77±1.72 vs 14.91±1.78 years old) and male predominance (57.3% vs 51.0%), had higher sleep dissatisfaction (50.1% vs. 46.2%), slept less (sleep duration 6.66 ± 1.54 vs 7.07 ± 1.51 hr), and had longer WCUS (2.94 ± 0.01 vs 2.15 ± 0.01 hr) than did those without asthma (p<0.001). The adjusted odds ratio (aOR) of suicidal ideation in those with short sleep duration (defined by ≤5h) was 1.41 (95% Confidence Interval [CI], 1.24–1.60). Notably, long WCUS (≥2hr) was significantly associated with a decreased risk of suicidal ideation (aOR, 0.82 [95% CI, 0.78-0.88], p<0.001).Conclusions: Although further research is needed to clarify this association, under the condition of sleep deprivation, WCUS at certain extent might be associated with low risk for suicidal ideation in adolescents with asthma.
