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
Objective: Little is known regarding the effect of sleep duration and
weekend catch-up sleep (WCUS), sleep time on weekends that exceeds sleep
time on weekdays, on suicidal ideation among adolescents with asthma. We
explored whether sleep factors were associated with suicidal ideation
among adolescents with asthma. Hypothesis: Adolescents with asthma are
likely to have shorter sleep duration and longer WCUS than those without
asthma. Study Design: Secondary data analysis for cross-sectional,
self-administered, online survey. Patients Selection: Adolescents
participating in the annual Korean Youth Risk Behavior Web-based Surveys
(KYRBS, completed from 2013 to 2017). Methodology: 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 34,067 and 363,003 adolescents with and without asthma,
respectively, adolescents with asthma had poorer sleep satisfaction
(44.6% vs. 42.6%), slept less (sleep duration 6.59 ± 0.94 vs 7.29 ±
1.45 hr), and had longer WCUS (3.13 ± 0.01 vs 2.29 ± 0.01 hr) than did
those without asthma. The odds ratio (OR) of suicidal ideation in those
with short sleep duration (defined by ≤5h) was 1.37 (95% Confidence
Interval [CI], 1.30–1.43). Notably, long WCUS (≥2hr) was
significantly associated with a decreased risk of suicidal ideation (OR,
0.88 [95% CI, 0.86–0.93]). Conclusion: Although further research
is needed to clarify this association, long WCUS, which is a
compensatory phenomenon for insufficient weekday sleep, protects against
suicidal ideation in adolescents with asthma.
