临床医学专业学生视力现状及运动干预研究

Investigating the visual acuity status in students majoring in clinical medicine and evaluating the efficacies of exercise intervention

目的:了解临床医学专业学生视力现状及发展趋势,对比分析体育运动对视力下降的干预效果。方法:采用测量法连续3年跟踪测量2016、2017、2018级入学新生的视力,测量2016级学生三学年的每学年视力,测量2017级篮球、乒乓球、武术俱乐部会员及非俱乐部会员视力,使用SPSS 18.0对数据进行统计分析,组间比较采用χ2检验和χ2趋势检验。结果:连续3年入学新生视力不良率依次为84.31%、87.22%和89.17%,呈逐年上升趋势,2016级学生三学年内视力不良率呈上升趋势(χ2趋势=16.719,P=0.000),2017级俱乐部会员与非俱乐部会员一学年内视力不良发生率有差异(χ2=11.430,P=0.010)。结论:临床医学专业学生视力不良率居高不下,防控形势严峻,运动干预能有效预防近视的发生,改善学生视力状况,缓解视力下降速度。

objective:To understand the current status and development trend of visual acuity in students majoring in clinical medicine,and assess the outcomes of exercise intervention in delaying the visual acuity.Methods:Visual acuity was generally measured in 3 consecutive years in the freshmen enrolled in ouRcollege in 2016,2017 and 2018.The changes of visual acuity were followed every academic yeaRin students enrolled in 2016 foRthree years.Still,eyesight was measured in club members(students enrolled in 2017)with basketball,table tennis and martial arts,and those outside the club.The recorded data were statistically analyzed using software SPSS(Ver.18.0),and subjected to Chi-square test andχ2-trend test.Results:PooRvisual acuity was 84.31%,87.22%and 89.17%,respectively,foRstudents enrolled in 2016,2017 and 2018,particularly worsened eyesight tended to increase foRthe students enrolled in 2016 in 3 consecutive years(χ2 trend=16.719,P=0.000).Incidence of visual acuity was significantly different between club members aforementioned and those outside the club in yeaRtime in students enrolled in 2017(χ2=11.430,P=0.010).Conclusion:The rate of pooReyesight remains higheRin students majoring in clinical medicine,which is serious in following prevention and control tasks.Yet,exercise intervention may lead to effective prevention,improvement and delay of the visual acuity.
