Popis: | This study examined the association between smart device usage and the 1-year change in refractive error among a representative sample of Hong Kong children and adolescents aged 8&ndash 14 years. A total of 1597 participants (49.9% male, mean age 10.9, SD 2.0) who completed both baseline (2017&ndash 2018) and 1-year follow-up (2018&ndash 2019) eye examinations were included in the present study. The non-cycloplegic auto-refractive error was measured and the average spherical equivalent refraction (SER) was analyzed. The participants also self-reported their smart device usage at baseline. Multivariate regression adjusted for age, sex, baseline SER, parents&rsquo short-sightedness, BMI, time spent on moderate-to-vigorous physical activity (MVPA), and caregiver-reported socio-economic status showed that, compared with the reference group (< 2 hours per day on both smartphone and tablet usages), those who spent &ge 2 hours per day using a smartphone and < 2 hours per day using a tablet had a significantly negative shift in refractive error (1-year change in SER &minus 0.25 vs. &minus 0.09 D, p = 0.01) for the right eye, while the level of significance was marginal (1-year change &minus 0.28 vs. &minus 0.15 D, p = 0.055) for the left eye. To conclude, our data suggested spending at most 2 hours per day on both smartphones and tablets. |
