Objective:
To understand the prevalence of low vision among Tujia and Han children and adolescents in Tujia inhabited areas, and to provide reference for the prevention and control of myopia in children and adolescents in minority areas.
Methods:
A cluster sampling of Tujia and Han primary school students from two primary schools in Lichuan City, Enshi Tujia and Miao Autonomous Prefecture, Hubei Province (2 466 Tujia and 971 Han) were selected for visual acuity assessment. Univariate χ 2 test and multivariate Logistic analysis were used. Low vision and associated factors between Tujia and Han nationality were compared.
Results:
The overall detection rate of low vision among children and adolescents in Tujia inhabited areas was 44.9%. There were differences in the degree of low vision in the left and right eyes of individuals, and the detection rate of low vision varied significantly by ethnic, gender and grade ( χ 2=22.10, 18.43, 19.06, 17.97 for the left eye, 17.52, 20.44, 21.49, 18.61 for the right eye, P < 0.05). There were many factors affecting low vision among children and adolescents in Tujia inhabited areas, overweight and obesity were negatively associated with low vision ( OR=1.81, 1.70, 95%CI=1.76-1.92, 1.66-1.82, P <0.01).
Conclusion
Low vision is highly prevalent in Tujia children and adolescents. Effective intervention measures should be taken to treat and prevent myopia in children and adolescents.

Objective:
To understand physical activity status of children and adolescents in Tujia inhabited areas, and to provide reference for the intervention model of physical activity of children and adolescents in minority areas.
Methods:
A cluster sample of 2 466 Tujia pupils from two primary schools in Lichuan City, Enshi Tujia and Miao Autonomous Prefecture of Hubei Province was selected to investigate physical activity status of Tujia pupils. The univariate χ 2 test was used to analyze the physical activity status of Tujia children and adolescents and its influencing factors.
Results:
The median duration of high intensity activity was 49.9 minutes/day in the last week, and 47.93% of participants met the physical activity standard( χ 2=80.47, P <0.01), the median duration of sitting was 396.1 minutes/day in the last week, and the qualified rate of screen time was 78.99%, and the differences of qualified rate between daystudents and residential students were of statistical differences( χ 2=35.12, P <0.01)).
Conclusion
The children and adolescents in the Tujia community are lack of physical activity. Therefore, it is necessary to take effective intervention measures to pay attention to the children and adolescents physical activity.
