A Randomized Experimental Study Of Information Intervention On Rural Students' Vision Health Cognition

With the continuous improvement of the social and economic level,health is getting more and more people's attention,and health behavior decision-making is affected by many factors,and health cognition is a very important factor.From the cognitive to the behavioral process,different results are produced because of the completeness and symmetry of the information.The demand for vision health services in rural areas is obviously insufficient.The glasses possession rate and wearing rate of myopia students are very low.The most important reason is that students and parents have misunderstandings about myopia problems and wearing glasses in rural areas.An effective way to cope with the lack of knowledge is to intervene in information,evaluate the impact on students' visual health perception through the implementation of information intervention,and provide favorable motivation for students' health behavior decision-making.At the same time,individual students can also identify their own vision status.Have a correct understanding and understanding of vision-related knowledge,so as not to have a misunderstanding of vision problems and affect their personal vision health protection behavior.From the perspective of health economics,this paper uses Randomized Control Trails to study the impact of information intervention on students' visual health perception in rural areas,so as to better understand the visual health perception of students in rural areas,and at the same time scientifically Evaluate the effect of information intervention on students' visual health perception,and provide effective education guidance for students,their parents and schools and other relevant departments,and lay a good foundation for students' vision health services in rural areas.In this study,a total of 6,897 students in the fourth and fifth grades of 84 schools in rural areas of provinces A and B were selected,and questionnaires were conducted on students' basic personal information,family information and school information,and visual health awareness.Firstly,the status of current students' visual health cognition is described.Secondly,the effect of information intervention on students' visual health cognition is evaluated by random intervention experiment.The research conclusions are as follows:First,the current level of visual health awareness among students in rural areas is poor.Specifically,40.4%(418/1036)of the students knew that myopia was not clear in the distance;only 18.7%(194/1036)of the students knew that myopia was caused by eyeball deformation;14.4%(149/1036)Students believe that eye exercises can't solve myopia problems;48.4%(501/1036)students think that myopia without glasses will affect learning;only 18.2%(188/1036)students think that myopia problems can be solved by wearing glasses;36%(373/1036)of the students think that the degree of myopia is also small,and glasses are needed;22.7%(235/1036)of the students think that wearing glasses will not make the eyesight worse and worse;33.7%(349/1036)students think that the primary school students Myopia should also wear glasses.The correct answer rate of students' knowledge about vision-related knowledge is less than 50%,indicating that students in rural areas have low levels of visual health awareness.Second,information intervention has a positive impact on improving students'visual health perception.Through the implementation of information intervention,the correct rate of students' perception of vision health has been improved.The specific performance is as follows:for the answer to the problem of myopia,the intervention group is 23.5%higher than the control group(P<0.01);Myopia without glasses would affect the learning response.The correct rate of the intervention group was 13.9%higher than that of the control group(P<0.01).For those with small myopia,the glasses should be answered.The intervention group was 17.8%higher than the control group(P<0.01).The intervention group did not make the vision worse and worse,the intervention group was 17.1%higher than the control group(P<0.01);the primary school pupils should also wear glasses to answer the myopia,the intervention group was 19.1 higher than the control group.%(P<0.01).Therefore,information intervention has a positive effect on the improvement of students' visual health awareness.The research suggests the following:First,schools should strengthen health and health education,rely on health education related courses,and actively use school radio,publicity columns,parent-child meetings,etc.to develop scientific eye health education for students and parents;at the same time strengthen vision health management,will be myopia The prevention and control knowledge is integrated into classroom teaching,campus culture and daily behavioral norms of students;the strength of the medical office(health room,school hospital,etc.)is strengthened,and school doctors and necessary medical equipment and related monitoring and inspection equipment are equipped according to the standard.Second,individual students should strengthen their health awareness,take the initiative to learn scientific knowledge of eye protection and other health knowledge;actively pay attention to their visual status,and when they feel their visual acuity changes significantly,they should inform parents and teachers in time to check and treat them.
