Abstract:
【Objective】 To analyze nutrition-related factors that affect the prevalence of myopia in adolescents, in order to provide reference for primary prevention of myopia. 【Methods】 A stratified sampling method was used to select 385 adolescents from Zhengding County in October 2021. Adolescents in this study took vision testing, physical examination and completed a questionnaire survey. One-way analysis of variance and lasso regression were used to screen the variables, and Logistic regression was used to determine the possible influencing factors of myopia. Factor analysis was adopted to extract the dietary patterns of adolescents in Zhengding County, then the association between dietary patterns and myopia was analyzed. 【Results】 A total of 385 adolescents were surveyed, with the prevalence rate of myopia of about 68.6%. Multivariate analysis revealed that fried food(OR=8.480, 95%CI:1.058 - 67.971) was a risk factor for myopia, while intake of milk and dairy products(OR=0.994, 95%CI:0.991 - 0.999), soybeans and nuts(OR=0.997, 95%CI:0.994 - 0.999), no myopia in either parent(OR=0.312, 95%CI:0.115 - 0.845), physical education class 4 times per week(OR=0.269, 95%CI:0.074 - 0.984) were statistically associated with a lower risk of myopia(P<0.05). Three dietary patterns was extracted through factor analysis, including diversified dietary pattern, soy-hybrid dietary pattern, and snack and beverage dietary pattern. Logistic analysis results indicated that soy-hybrid dietary pattern(OR=0.85, 95%CI:0.73 - 0.99,P<0.05) was statistically associated with myopia. 【Conclusions】 The problem of myopia among adolescents in Zhengding County is more serious. Increasing the intake of milk and dairy products, soybeans and nuts, reducing the intake of fried foods, and adjusting the overall dietary structure should be recommended in order to prevent the development of myopia in adolescents.
