摘要
目的探究网球运动对小学三年级学生视力健康的影响,为采取有效措施预防近视的发生提供依据。方法于2021年9月选取北京市人大附中丰台学校三年级学生共202名,随机分为干预组75名和对照组127名,两组除参加相同的文化课程和体育课程外,干预组另外每周增加2次网球课程,并在干预前(2021年9月)、中(2022年1月)、后(2022年6月)对其进行视力测试。干预方法和不同时间点测量的资料为重复资料两因素多水平的分析,区组间比较采用独立样本t检验,时间点因素的分析采用单因素重复测量方差分析。结果干预后,男生第3次视力测试干预组左眼和右眼平均视力均高于对照组(左眼:5.00±0.13,4.88±0.29;右眼:5.00±0.12,4.88±0.30,t值分别为2.33,2.36,P值均<0.05)。女生第2次视力测试(左眼:5.03±0.17,4.86±0.21;右眼:5.03±0.15,4.85±0.23)和第3次视力测试(左眼:4.97±0.13,4.81±0.23;右眼:4.97±0.14,4.82±0.24),干预组左眼和右眼平均视力均高于对照组(第2次:t值分别为3.84,3.87;第3次:t值分别为3.70,3.46,P值均<0.01)。干预后对照组男、女生视力不良检出率在3次测试中均升高,差异均有统计学意义(χ^(2)值分别为17.86,34.77,P值均<0.01)。第1次视力测试,男、女生的对照组和干预组视力不良检出率的差异均无统计学意义(χ^(2)值分别为0.01,0.10,P值均>0.05);干预组男生第3次视力检出不良率低于对照组(20.00%,45.45%),干预组女生第2,3次视力不良检出率均低于对照组(22.86%,54.00%;28.57%,70.00%)(χ^(2)值分别为7.34;8.24,14.18,P值均<0.01)。结论网球运动在一定程度上可以缓解或预防小学生近视的发生。应积极推广网球运动等体育运动,以保护小学生视力健康。
Objective To explore the impact of tennis on the visual health of primary school students,so as to provide a basis for myopia prevention.Methods In September 2021,a total of 202 third grade students from Fengtai Affiliated School of Renmin University of China in Beijing were recruited,with 75 students in the intervention group and 127 students in the control group.In addition to attending the same cultural and physical education courses,the intervention group added a tennis course twice a week and tested their vision before the intervention(September 2021),middle(January 2022)and later(June 2022).Data collected at different time points in the two groups were analyzed by using independent sample t-test for comparison between blocks,and single-factor repeated measurement ANOVA for analysis of time point factors.Results After intervention,among male subjects,the average visual acuity of the left and right eyes in the intervention group were higher than that in the control group at the third visual acuity test(left eye:5.00±0.13,4.88±0.29,right eye:5.00±0.12,4.88±0.30,t=2.33,2.36,P<0.05).Among female subjects,the second visual acuity test(left eye:5.03±0.17,4.86±0.21,right eye:5.03±0.15,4.85±0.23)and the third visual acuity test(left eye:4.97±0.13,4.81±0.23,right eye:4.97±0.14,4.82±0.24)showed that the average visual acuity of the left and right eyes in the intervention group were higher than that in the control group among females(second:t=3.84,3.87,third:t=3.70,3.46,P<0.01).After intervention,the detection rate of visual impairment in both males and females control groups increased at three tests,with statistically significant differences(χ^(2)=17.86,34.77,P<0.01).In the first visual acuity test,there was no statistically significant difference in the detection rate of visual impairment between the control group and the intervention group for both males and females(χ^(2)=0.01,0.10,P>0.05).The third visual impairment detection rate of males in the intervention group was lower than that of the control g
