中学生近视眼预防的干预效果评价

Objective To analyze the intervention effect of myopia prevention among middle school students. Methods Two hundred middle school students monitored in our department from March 2021 to October 2023 were selected as the research objects. They were divided into the conventional group and the prevention group by the random number table method. Myopia prevention intervention was provided for the prevention group, and routine management was carried out for the conventional group. The prevention effects of the two groups were compared. Results The total incidence of myopia among middle school students in the prevention group was lower than that in the conventional group (P＜0.05). The incidence of incorrect reading and writing postures in the prevention group was lower than that in the conventional group (P＜0.05). The proportion of students with reading and writing time exceeding 6 hours in the prevention group was lower than that in the conventional group (P＜0.05). And the rate of daily outdoor activity time less than 3 hours in the prevention group was lower than that in the conventional group (P＜0.05). The myopia rate of one or more parents in the prevention group and the conventional group was similar (P＞0.05). Before the intervention, the cognition of myopia prevention measures such as correct sitting posture, correct eye exercises, correct eye usage habits, and regular examinations in both groups was relatively low (P＞0.05). After the intervention, the students in the prevention group had higher cognition of myopia prevention measures such as correct sitting posture, correct eye exercises, correct eye usage habits, and regular examinations than those in the conventional group (P＜0.05). Conclusion Active prevention of myopia can reduce the incidence of myopia among middle school students and should be further studied and promoted.
