Study On The Status Quo And Influencing Factors Of Freshmen’s Vision From A University In Henan

ObjectiveTo explore the influencing factors of poor vision in freshmen and provide scientific bases for effective precautions for the young, this paper studies the vision status quo and characteristics of the freshmen from a university in Henan province.MethodsFrom2006to2010, a vision survey was undertaken among16751freshmen from a university in Henan who also filled questionnaires. Data were input and processed by the Epidata3.0and SPSS12.0software respectively.Results1. Among the16751participants, there are8634male and8117female;9257came from urban areas and7494from rural areas.8441participants are below19years old and the rest are above19years old. the total poor vision rate of the participants is86.02%(14409/16751) among which the average mild, moderate, and severe vision defect rates are8.01%,15.69%,62.32%respectively. There is a drop of3.28%in2010than that of2006, which is statistically significant (χ2=14.574, P<0.05).2. There are distinct contrasts among different genders, different household registers and different ages in vision defect. From2006through2010the average malvision rate in male freshmen is lower than that of female counterparts (86.92%vs85.17%), which is significant statistically (χ2=10.550, P<0.05). The average malvision rate of male freshmen in different years is also lower than that of the female counterparts (P<0.05); Through the years2006to2010the rate of overall malvision students of urban areas declines, whereas the overall rate of that from rural areas rises. In2006malvision rate in urban origin freshmen is greater than that in rural origin (χ2=46.252, P<0.05). From2006to2010the malvision rate gap between these two groups is narrowed year by year and is almost the same since2009. The malvision rate in the group aged over19is higher than that of the rest groups from2006to2010. There also exists difference between the comparison in the same year (P<0.05), which is statistically significant (χ2=16.749, P<0.05).3. The influencing factors for malvision areha parents myopia, the stone-cast distance between the reading materials and eyes, the inappropriate way of eye relaxation, the insufficient outdoor activities time, and absence of eye exercises.ConclusionsOverall, there is a downward trend in malvision rate in freshman from a university located in Henan from2006to2010, but this rate still remains at a relative high level. And the differences exsists in terms of different genders, household registers and ages, and the differences are increasing with age. The risk factors for malvision are parents myopia, the stone-cast distance between the reading material and eyes, the inappropriate way of eye relaxation, the insufficient outdoor activities time, and absence of eye exercises. The malvision is caused by various factors, which should arouse the attention of the health department, the school and the society to take measures against malvision.
