A preliminary study on vision health education mode for children on campus in Liuzhou

Abstract

Objective To provide scientific basis for seeking an effective and long-term practical value of children′s Health Promotion School model by investigating and analyzing vision and myopia cognition status before and after the intervention. Methods Taking class as the unit, 564 primary school students in grade three in Liuzhou city were randomly selected as the research object and divided into three groups. A group of parents of students in the intervention group, organize the students in health education and training, health education materials distributed to parents; a group for students, students in health education and training; one was control group, without any intervention. Among them, 283 boys and 281 girls, the age range of 8~9 years old, the average age of 8.6 years old. Field survey was used to measure visual acuity and to investigate the related visual acuity questionnaire. After 6 months of intervention, visual acuity test and vision related knowledge test were performed again. After the intervention, three groups of test results by the mean and standard deviation (±s), before and after the intervention group vision than using rank sum test, compared with the three groups after the intervention of the test results of single factor analysis of variance, the difference was statistically significant when compared with each other, further using LSD-t method. Results Before intervention, the visual acuity of the three groups was compared, and there was no significant difference between the three groups by rank sum test (u=1.69, P>0.05), indicating that there was comparability between the two groups. The visual acuity of the intervention group after intervention was statistically significant (u=1.69, P 4.8 in the two intervention groups increased before intervention, and the percentage of visual 4.8 in control group was decreased before intervention, and the percentage of visual the students intervention group visual acuity > the control group vision. Compared with each other, there were significant differences between the intervention group and the student intervention group (u=-4.41, -3.15; P 0.05). The intervention of parents of students in intervention group and intervention group students in subjects with cognitive scores, students and parents eye health scores cognition scores were higher than the control group, there were statistically significant differences in cognitive performance for [(t=-3.55, -6.54; P 0.05). In the aspect of parents′ cognition, the scores of parents′ group > students′ group > control group′s scores, the difference between parents′ intervention group and students′ intervention group was statistically significant (t=4.94, P<0.05). Conclusion Children′s Health Vision Promotion School model is meaningful to control myopia rate and worthy of spreading. Key words: Campus; Vision; Education
