Effects of school myopia management measures on myopia onset and progression among Chinese primary school students.

Background: Schools play an organizational role in managing myopia-related behavioral habits among students. We evaluated the effects of school myopia management measures on myopia onset and progression in a school-based prospective 1-year observational study.

Methods: In total, 8319 children from 26 elementary schools were included.

Longitudinal association between the timing of adiposity peak and rebound and overweight at seven years of age.

Background: The timing of adiposity peak (AP) or adiposity rebound (AR) is a determinant of overweight or obesity in adolescence and adulthood. However, limited studies have reported the association in young school-age children. We aimed to evaluate this association and explore the role of health behaviours in it.
