Purpose: To investigate the myopigenic activity change and its risk factors in urban students in Beijing. Methods: A total of 241 primary or secondary students aged 6-17 years from the Beijing Myopia Progression Study (BMPS) were re-examined 3 years after their baseline enrollment. A detailed questionnaire was administered to assess myopigenic activities at both baseline and at the 3-year follow-up. Altogether, 217 students (90.0%) with completed data were included in the analysis. Results: Compared to baseline, primary students (n = 123) had significant increases in outdoor sports time (mean standard deviation: 3.5 +/- 4.3 vs. 2.4 +/- 3.0 hours/week, p = 0.02), near work time (32.1 +/- 13.4 vs. 24.8 +/- 9.2 hours/week, p < 0.001), diopter hours (128.8 +/- 53.3 vs. 97.5 +/- 35.9 diopter hours/week, p < 0.001), and indoor time (53.8 +/- 22.8 vs. 41.4 +/- 16.9 hours/week, p < 0.001) at the 3-year follow-up. At both baseline and follow-up, females spent less time than males on outdoor sports (baseline: 2.4 +/- 2.8 vs. 4.0 +/- 5.2 hours/week, p = 0.006; follow-up: 2.3 +/- 3.1 vs. 5.1 +/- 5.0 hours/week, p < 0.001), and total outdoors (baseline: 11.9 +/- 7.9 vs. 14.4 +/- 9.5 hours/week, p = 0.03; follow-up: 10.5 +/- 8.2 vs. 13.9 +/- 9.6 hours/week, p = 0.005). In the multivariate regression analysis after adjustment by student's gender, younger students had more increase in both near work time (slope = -0.99 hours/week for age, p = 0.009) and indoor time (slope = -2.04 hours/week for age, p = 0.001). Conclusions: During the 3-year follow-up, primary students had more myopigenic activities. Female students had more myopigenic activities than males at both baseline and follow-up. Children's age was a significant risk factor for this myopigenic activity change.
