Abstract：Objective To explore the living environment factors for infants with ametropia. Methods A random cluster sampling method was used to select 462 infants (924 eyes) aged 1-3 years from outpatients in the child health care institutions in Chuzhou City from July to August in 2017 to serve as the surveyed subjects. Their refractive status was screened and diagnosed by the US Welch Allyn Sure Sight Vision Screening Instrument. A questionnaire survey was conducted among their parents to investigate and compare the differences in the living environment factors (including eating habits, living and sleeping environment and eye use habits) between infants with and without ametropia. A Logistic regression model was employed to analyze the key influencing factors. Results A total of 343 infants without ametropia and 119 infants with ametropia were detected in this study. Compared with the infants without ametropia, lower proportions of the infants with ametropia often ate fish, carrot, green vegetables and hard food, had better sunlight in the house and took daily outdoor activities more than 30 minutes, while higher proportions of the infants with ametropia never ate fried food, suffered passive smoking, slept with light on, often cried, liked to see bright light, and watched TV with eyes not level with the TV set. Multivariable logistic regression analysis showed that often eating green vegetables (OR=0.122) and often eating hard food (OR=0.357) were the protective factors of ametropia, whereas watching TV with eyes not level with the TV set was the risk factor (OR=1.381). Conclusions The infants’ ametropia is related to their diet habits and eye use habits.
