Association between quality and duration of sleep and subjective cognitive decline: a cross-sectional study in South Korea

Abstract Sleep is being emphasized as a factor that improves mental health and quality of life. Here, we aimed to investigate the association between the quality and duration of sleep and subjective cognitive decline in the Korean population. We used the 2018 Korean Community Health Survey data that...
