Decreased Sleep Quality in High Myopia Children

  • 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.
