Abstract
OBJECTIVE
Restless legs syndrome (RLS) is a common sleep disorder among adolescents. This study aimed to investigate the lifestyle factors and sleep disturbances associated with the symptoms suggestive of RLS in Korean adolescents.
METHODS
In this cross-sectional study, we investigated a total of 25,789 adolescents (mean age, 15.8 ± 1.7 years; male, 48.5 %). The presence of symptoms suggestive of RLS was assessed with a single question about RLS in the Global Sleep Assessment Questionnaire. We performed multiple logistic regression analysis to estimate the odds ratios (ORs) and 95 % confidence intervals (CIs) of lifestyle factors and sleep disturbances that were independently associated with adolescent RLS.
RESULTS
The prevalence of RLS-suggestive symptoms was 5.1 % among adolescents. After adjustment, lifestyle factors associated with symptoms suggestive of RLS were occasional alcohol consumption (OR, 1.245; 95 % CI, 1.006-1.540) and proneness to Internet addiction (OR, 1.027; 95 % CI, 1.021-1.033). Bedtime behaviors associated with RLS-suggestive symptoms were sleeping with a doll or pet (OR, 1.194; 95 % CI, 1.032-1.381) and sleeping with a TV or radio on (OR, 1.366; 95 % CI, 1.156-1.614). Male sex, frequent snoring and witnessed apnea, perceived sleep insufficiency, excessive daytime sleepiness were also associated with RLS-suggestive symptoms in adolescents.
CONCLUSIONS
Adolescents with symptoms suggestive of RLS were associated with different lifestyle factors compared to adults with RLS. Further research is needed to determine the clinical implications of lifestyle factors in adolescent RLS.
