BACKGROUND AND PURPOSE: To investigate the association between sleep hygiene practices and sleep disturbance in patients with Parkinson's disease (PD).
METHODS: A cross-sectional study was conducted involving 109 PD patients. Sleep disturbance and sleep hygiene were evaluated using the Korean version of Parkinson's Disease Sleep Scale-2 (K-PDSS-2) and the Sleep Hygiene Practice Scale-Korean version (SHPS-K), respectively. Multivariate linear regression analysis was performed, adjusting for potential confounding factors, such as age, body mass index, education, Hoehn and Yahr stage, cognitive function and depressive symptoms.
RESULTS: Higher SHPS-K scores, reflecting poorer sleep hygiene, were significantly associated with greater sleep disturbance (B=0.254, p<0.001). Among the SHPS-K subdomains, arousal-related behaviors and irregular sleep scheduling showed the strongest correlations with K-PDSS-2 scores, while eating/drinking and sleep environments were not significantly related.
CONCLUSIONS: Poor sleep hygiene is significantly associated with disturbed sleep in patients with early-stage PD. These findings support the potential utility of non-pharmacological interventions targeting modifiable behavioral factors to improve sleep-related outcomes in patients with PD.
