To present extra-curricular activities of children with myopia, to investigate whether these activities are associated with the degree of myopia and to compare these findings to historical data.
32 myopic children age 10 to 16 years (mean 13.2 ± 1.84 years with a spherical equivalent of -2.85 ± 1.48 D, ranging from -0.63 to -6.00 D) participated and their parents completed a survey on the child’s weekly time spent reading/studying for school assignments, reading for pleasure, watching TV, using computer/playing video games at home, and engaging in sports. Subjective refraction determined the degree of myopia. For historical data, reported values were compared to Mutti et al. (IOVS 2002;43:3633-3640), which used a comparable survey and included children of a similar age (13.5 ± 0.5 years).
The average time the children spent watching TV and using computers/playing video games was 12.5 ± 8.5 and 9.3 ± 6.7 hours/week, respectively. Compared to Mutti et al., these times were significantly greater (p=0.04 and p<0.01 for watching TV and using computer/playing video games, respectively). Average time spent on reading or studying for school was 7.72 ± 5.27 hours/week, which was significantly less than Mutti et al. (11.2 ± 7.2, p=0.02). There were no significant differences with respect to the time spent on reading for pleasure or engaging in sport activities (both p>0.05). The degree of myopia was inversely associated with the time spent on sport activities (r=0.42, p=0.02). No correlations were found between the degree of myopia and near-work activities (r=0.0-0.3, all p>0.05).
The time spent in activities such as TV, computers/video games and reading in myopic children appears to have increased over time and more of this time is being spent watching TV and using computers/playing video games. Our findings also suggest that children with higher myopia tend to be less engaged in sport activities.
