目的：了解三亚市河西区小学生视力不良状况,对引起近视的原因进行分析。 　　方法：对三亚市2所小学1218名1~6年级小学生进行视力及屈光度检查。对近视原因进行问卷调查。 　　结果：视力不良检出率为29.55%；近视随年级增高呈增高趋势；女生近视发生率较男生为高；患近视小学生户外活动时间为7.25±5.35h/wk,而非近视小学生户外活动时间则为11.86±6.65h/wk,两者差异显著(P<0.05)；患近视小学生看电视、电脑、手机时间为13.36±8.35h/wk,而非近视小学生看电视、电脑、手机时间为7.75±5.83h/wk,两者差异有统计学意义(P<0.05)。 　　结论：小学生近视的发生率明显上升；小学生近视的发生与户外活动时间减少及看电视、电脑和手机时间增多有关。

AIM:To evaluate the poor vision condition and analyze the myopia etiological factor in primary school He'xi district of Sanya. METHODS: A cohort of 1 218 subjects were recruited randomly from grade 1~6 of two primary schools. Visual activity test, dioptroscopy and risk factor questionnaire were evaluated. RESULTS: The prevalence of poor vision was 29. 55%. The incidence of myopia increased with grade, and was significantly higher in girls than that in boys. The outdoor activity time of myopic pupil ( 7. 25 ± 5. 35h/wk ) was significantly lower than emmetropic pupil (11. 86±6. 65h/wk) ( P < 0. 05 ). The usage of electronic product ( TV, computater and cell phone) time of myopic pupil (13. 36±8. 35h/wk) was significantly higher than emmetropic pupil (7. 75±5. 83h/wk) (P<0. 05). CONCLUSION: The increase of myopia incidence is closely related with sparing outdoor activity and excess usage of electronic product.
