Disordered Sleep and Myopia Risk among Chinese Children
The purpose of this study was to examine the correlation between disordered sleep and myopia among Chinese children.
1970 children were selected for investigation and refraction was conducted in 1961 (99.5%).
1912 (97.1%) children had questionnaires returned by their parents and 1902 (96.5%) among whom had complete examination and questionnaire data.
Myopia < = -0.50 Diopters was present in both eyes of 588 (30.9%) children (1329/3804 = 34.9% of eyes) examined.
1129 children (59.4%) had abnormal CSHQ scores (> 41).
The correlation between sleep duration and myopia was not significant (p = 0.199) for total (night + midday) sleep.
No consistent evidence found through the study that demonstrate the association between sleeping period and myopia.
