In 5 years, the number of patients with dry eye in different age segments is the highest in patients aged 41 to 60 years old. The fewest patients are under 18 years old and the total number of male patients is less than that of female patients.

图所示为2014—2018年261周每周NO2的平均浓度,有明显的周期性。
The figure shows the average weekly NO2 concentration for 261 weeks from 2014 to 2018, with obvious periodicity.
2.2 干眼患者与环境污染物NO2的相关性分析
将门诊患者的检查从每日转换为每周1次,由于人口的工作时间,门诊患者按周显示出强烈的周期性。转换后,门诊访问量为每周7~735例(图4 )。干眼的门诊就诊与NO2水平相关,95%CI为218.3~266.8,差异有统计学意义(P <0.0001)。通过计算其相关性系数为0.388,95%CI为0.298~0.479 ,差异有统计学意义( P < 0.0001),NO2水平和患病人数有显著相关性。在本研究评估的污染物中,每增加10 μg/m3的NO2暴露导致每周7 0次门诊就诊。暴露于NO2的单位增量提高了门诊访问次数(表3)。提示NO2的影响因素均对性别无特异性。对于年龄各年龄段干眼患者,NO2是环境污染造成干眼的主要因素(表3)。 本研究还考虑可能是由于空气污染物对干眼的患者数量有累加效应,因此又计算出每周患者累计人数与该周的空气污染物水平的相关性,结果如图5。提示NO2与干眼患者的门诊数增多呈显著正相关。本研究发现夏季的干眼门诊就诊次数明显多于其他季节(图6),但性别和年龄没有改变这种效果。
