近日,一项发表在JAMA子刊上中美学者进行的研究显示,从小学到初中,近视患病率增加5倍,高度近视增加20多倍。

近视,已成为中小学家长焦虑头疼的问题之一。

近日,一项发表在JAMA子刊上中美学者进行的研究显示,从小学到初中,近视患病率增加5倍,高度近视增加20多倍。

研究显示,在没有散瞳的情况下,一年级小学生近视患病率为12%,到初中即七年级则达到67.4%。其中高度近视在小学生发病率为0.1%,但到初中发病率则达2.3%。

而且不论小学生还是初中生,年近视发生率为20%~30%。

到大学如何呢?大学生90%近视。

近视不是一副眼镜的问题,也不仅是美观的问题,除了影响生活外,高度近视与近视性黄斑变形、青光眼和视网膜脱落等均相关。

怎样保护眼睛?

户外运动有助于保护视力。近日我国国家卫健委、教育部、国家体育总局联合发出通知,要求学生每天锻炼一小时。

该研究对广州市19所小学的小学生于2010-2015年进行了随访;对22所中学的中学生于2010-2012进行了随访。共纳入受试者4741例。
