The prevalence rate of obesity increased significantly in 2016 (P < 0.05) but that of poor eyesight, permanent teeth caries, and malnutrition showed a significantly declining trend (P < 0.05 for all). The prevalence rate of poor eyesight, obesity, and malnutrition were significantly higher (all P < 0.05) but the prevalence rate of permanent teeth caries was significantly lower (P < 0.05) among the high school students than those among the primary school students.
