•Prevalence of depressive symptom and perceived stress in disabled people is much higher than in the general population.•The trajectory group, which maintain the highest sleep duration over 3 years, had the highest risk of depressive symptoms and that maintain the lowest sleep duration had the highest of perceived stress out of all groups.•The management to promote sleep habits of optimal duration for people with disabilities is needed. Studies have reported that adults with disabilities reported frequents mental distress and duration of sleep was associated with mental health. Thus, this study investigated the longitudinal associations between sleep duration and mental health in disabled population in South Korea. The 1st-3rd data for 2nd wave of Panel Survey of Employment for the Disabled (PSED) data included 3,742 samples who responded three-year surveys. The association between sleep duration and mental health was examined using Chi-square test and trajectory analysis using generalized estimating equation (GEE) model. Of the 650 participants with depressive symptom, 199 participants with sleep duration of below 6 h or over 8 h were significantly higher in the symptom compared to those with sleep duration of 7 h. In the trajectory analysis, group with the highest level of sleep duration had the highest risk of depressive symptom and that with the lowest level of sleep duration had the highest risk of perceived stress out of all groups. These findings reveal the need for effective management to promote optimal duration of sleep by evaluating the sleep characteristics of the disabled. Graphical abstract presenting the six trajectory groups of people with disabilities over 3 years’ time. Out of all groups, the trajectory group 6 and 1 had the highest risk of depressive symptom and perceived stress, respectively. [Display omitted]
