Abstract
Purpose: Recent investigations described a host of disadvantageous myopia comorbidities including decreased QOL, depression, and sleep problems. The present study evaluated mental status and habitual sleep in young subjects with myopia based on the reported association between myopic error and psychiatric profiles. Methods: This cross-sectional study surveyed 153 university students using a questionnaire containing the Pittsburgh Sleep Quality Index (PSQI), Subjective Happiness Scale (SHS), short morningness/eveningness questionnaire, and Hospital Anxiety and Depression Scale (HADS). Results: Participants were classified as having high myopia (n = 44), mild myopia (n = 86), or no myopia (n = 23). The SHS and HADS scores in this cohort were significantly worse in the high myopia group than in the other two groups (p < 0.05, t-test). PSQI values were not significantly different among the three groups. Regression analysis correlated myopic error with poor SHS (p = 0.003), eveningness chronotype (p = 0.032), late wake-up time (p = 0.024), and late bedtime (p = 0.019). Conclusions: University students with myopia tended to be unhappy, have an eveningness chronotype, wake up late, and go to bed late compared to less myopic subjects. Optimal correction might, therefore, be beneficial to myopic students in addition to preventing progression to high myopia in early childhood to potentially avoid related negative effects on mental health and sleep habits in adolescence.
Highlights
Myopia is the most common ocular condition in adolescence [1,2]
We previously reported that laser-assisted in situ keratomileusis (LASIK) treatment for myopia contributed to patient happiness [17]
Pittsburgh Sleep Quality Index (PSQI) is composed of seven subscales and Hospital Anxiety and Depression Scale (HADS) is composed of depression and anxiety subscores
Summary
Myopia is the most common ocular condition in adolescence [1,2]. Conventionally recognized as a vision problem to be corrected with devices or surgery, myopia is closely associated with an increased risk of retinal detachment, glaucoma, macular degeneration, and cataract [3,4,5]. Myopia shows the most rapid progression in younger individuals, making university students a suitably aged group in which to observe mental and neuropsychiatric status after myopic progression in early childhood In addition to their age, university students are less likely to do shift work, chronotype (morningness-eveningness) can vary widely among students with a Japanese study, demonstrating that students with eveningness chronotype had a higher average alcohol intake and smoking habit, and were more likely to skip breakfast [37]. They are in the transitional period in aspect of myopia progression and lifestyle, and might be unaware of the ocular complications of myopia, such that any evaluation of mental status corresponding to myopic error would have a small bias. This study evaluated subjective happiness, sleep, and mood status in university students, and the first comprehensive study on this topic in a young population with myopia
