- The purpose of this study was to examine the sleep quality in high myopic children and adults.
- This was a cross sectional study with 486 participants aged from 10 to 59 years with refractive errors.
- A questionnaire containing the Pittsburgh Sleep Quality Index (PSQI) and Hospital Anxiety and Depression Scale (HADS) was used to generate findings.
- Children aged 20 years or less in the high myopia group displayed the poorest PSQI scores (P < 0.01), while the adults showed no such correlations.
- Subscales of PSQI and HADS in children showed that the high myopia groups had the shortest sleep duration (P < 0.01), worst subjective sleep scores (P < 0.001), and latest bedtime (P < 0.05).
- Regression analyses in children correlated myopic errors with PSQI (P < 0.05), sleep duration (P < 0.01), and bedtime (P < 0.01).
- Sleep efficacy (P < 0.05) and daytime dysfunction (P < 0.05) were significantly better in contact-lens users compared to the respective non-user groups in all participants.
- The sleep quality in children was highly correlated with myopic error, and with the high myopia group worst affected.
