Abstract:
Objective:To gain a understanding of the current situation and influencing factors of poor vision in 6-year-old children in Heilongjiang Province, and to provide a reference basis for formulating effective prevention and control strategies for poor vision.Methods:From August to October 2024, a non probability sampling method was used to select 6-year-old children in Heihe City, Jiamusi City, Hegang City, Suifenhe City, Dongning City, and Dorbod Mongol Autonomous County for vision examination and questionnaire survey. The questionnaire survey included electronic screen usage, close range eye habits, outdoor activities and sleep conditions, vision examination results, interests and dietary habits, and the influencing factors of poor vision were analyzed.Results:A total of 6 342 6-year-old children were surveyed, with a detection rate of 29.234% (1 854/6 342) for poor vision. Five thousand seven hundred and twenty-one valid questionnaires were recovered, with a valid questionnaire rate of 90.208%. Logistic multivariate analysis showed that daily TV viewing time (≥2 h), daily computer usage time (≥1 h), daily use of mobile electronic devices (≥1 h), turning off lights when watching electronic screens after dark, resting frequency when using close range eyes (≥0.5 h rest once), parental myopia, frequent picky eating habits, and a preference for sweet foods (desserts, fruits, ice cream) were independent risk factors for poor vision in 6-year-old children ( P < 0.05). The distance between the eyes and the computer display screen exceeding 66 cm, the distance between the eyes and the TV display screen exceeding 3 m, and the daily outdoor activity time (≥3 h) were independent protective factors ( P < 0.05). Conclusions:The detection rate of poor vision in 6-year-old children in Heilongjiang Province is relatively high, and factors such as electronic screen usage, close range eye habits, outdoor activities, and dietary habits are all influencing factors. In the future, we should raise children's awareness of vision protection and develop scientific and effective prevention and control strategies to reduce the incidence of poor vision in children and adolescents.
