Elderly patients are apt to assume that they "understand well", therefore, in order to recognize and close the perception gap between elderly patients and medical professionals, it is necessary to provide them with more aggressive (frequent) instructions on inhalation therapy.
[Purpose] This study aimed to examine the prevalence of locomotive syndrome among
patients with obstructive sleep apnea syndrome (OSAS) using the “loco-check” recently
developed by the Japanese Orthopedic Association, and to compare health-related quality of
life (HRQOL) among patients with and without locomotive syndrome. [Subjects and Methods]
This cross-sectional study evaluated 1,195 outpatients with OSAS (1,030 males and 165
females). Locomotive syndrome was evaluated using the Japanese Orthopedic Association’s
“loco-check”. HRQOL and psychological distress were evaluated using the EuroQol
5-dimensional (EQ-5D) and 6-item Kessler questionnaires. [Results] Locomotive syndrome was
detected in 578 patients (48.4%), including 398 males (38.6% of males) and 119 females
(70.3% of females). Patients with OSAS and locomotive syndrome had significantly lower
EQ-5D scores, compared to patients without locomotive syndrome. Multiple regression
analysis revealed that HRQOL among patients with OSAS was independently associated with
locomotive syndrome, age, gender, body mass index, apnea hypopnea index, the Japanese
version of the Epworth Sleepiness Scale score, and exercise habits. [Conclusion] The
prevalence of locomotive syndrome was thought to be comparatively high in patients with
OSAS, and locomotive syndrome was associated with lower HRQOL, even after adjusting for
confounding factors. Prevention or management of locomotive syndrome may be beneficial for
improving HRQOL among patients with OSAS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
