Abstract:

Objective To explore the relationship between adolescents' sedentary behavior and poor vision.

Methods Both subjective (352 adolescents) and objective (331 adolescents) methods were used to measure the sedentary behaviors of adolescents aged twelve to 17 years in two phases with an interval of 14 weeks, to investigate the influence of different sedentary behaviors on the incidence of poor vision acuity in adolescents.

Results The sedentary time of adolescents was generally long, among which educational sedentary time and screen sedentary time accounted for a higher proportion. The detection rate of poor visual acuity among adolescents was significantly lower in low sedentary group/low education sedentary group than in high sedentary group/high education sedentary group (|t| > 3.422, P < 0.01). The objective measurement showed that the average daily sedentary time was significantly negatively correlated with the eyesight level in the first phase (r= -0.176, P < 0.001). The subjective measurement showed that the educational sedentary time was significantly negatively correlated with the eyesight level both in the first phase (r= -0.188, P < 0.001) and the second phase (r= -0.141, P <0.001). After controlling for moderate to vigorous physical activity, the objectively measured average daily sedentary time had no significant predictive effect on the poor vision of adolescents, and the subjectively measured educational sedentary time could significantly negatively predict the eyesight level of adolescents (β= -0.124, P= 0.026), however, there was no cross-lag effect between the two variables. The critical value analysis showed that the maximum value of Youden index was 0.206, corresponding to the educational sedentary time of 3 445 minutes a week, the sensitivity was 0.738, and the specificity was 0.467.

Conclusion Adolescents with high sedentary group have higher detection rate of poor vision. Educational sedentary has a significantly negative predictive effect on the eyesight level of adolescents. The detection rate of poor vision would increase if the educational sedentary time of adolescents is longer than 3 445 minutes a week.
