目的对大学生视力低下情况进行调查,为采取防治措施提供依据。方法分别在2010年9月及2012年9月对曲阜师范大学2010级340名在校大学生进行问卷调查并进行视力测试。计数资料采用χ2检验,P<0.05为差异有统计学意义。结果 2010年视力低下179例,占52.65%;2012年视力低下235例,占69.12%。两者比较差异有统计学意义(χ2=19.364,P<0.05)。2012年轻度视力低下比例(23.40%)高于2010年(11.73%),但重度视力低下比例(48.94%)低于2010年(60.89%),比较差异均有统计学意义(χ2=9.237、5.851,均P<0.05)。2010、2012年男女视力低下情况比较差异均无统计学意义(χ2=0.905、0.417,均P>0.05),2010年与2012年相比男女视力低下情况差异无统计学意义(χ2=0.043,P>0.05)。2010、2012年农村(32.40%、36.17%)与城镇(67.60%、65.11%)视力低下情况比较差异均有统计学意义(χ2=21.779、42.902,均P<0.05)。结论大学生视力低下情况严重,采取必要的防治措施刻不容缓。
Objective To investigate the under-eye condition of undergraduates and provide the basis for prevention and control measures. Methods In September 2010 and September 2012 respectively, 340 college students from Grade 2010 in Qufu Normal University were surveyed and their eyesight tests were conducted. Count data using χ2 test, P <0.05 for the difference was statistically significant. Results In 2010, 179 eyes were low vision, accounting for 52.65%; in 2012, 235 cases were low vision, accounting for 69.12%. The difference between the two was statistically significant (χ2 = 19.364, P <0.05). The prevalence of mild vision loss in 2012 was 23.40% higher than that in 2010 (11.73%), but the rate of severe vision loss (48.94%) was lower than that in 2010 (60.89%), with significant difference (χ2 = 9.237, 5.851, all P <0.05). There was no significant difference in visual acuity between men and women in 2010 and 2012 (χ2 = 0.905,0.417, all P> 0.05). There was no significant difference in visual acuity between men and women in 2010 and 2012 (χ2 = 0.043, P > 0.05). In 2010 and 2012, the poor eyesight in rural areas (32.40%, 36.17%) and urban areas (67.60%, 65.11%) were significantly different (χ2 = 21.779, 42.902, all P <0.05). Conclusions The under-vision of undergraduates is serious, so it is urgent to take the necessary prevention and treatment measures.
