AIM:To investigate the current status of astigmatism and its associated factors among children and adolescents from kindergarten through senior high school in Yangpu District, Shanghai, and to provide scientific evidence for the prevention and control of refractive errors.METHODS:A cluster sampling method was employed. From September to November 2024, students from 14 randomly selected schools in Yangpu District, Shanghai, were enrolled as study subjects. Autorefraction and ocular biometry were performed under non-cycloplegic conditions, and questionnaire surveys were administered. Comparisons of astigmatism degree, detection rate, and axis were made across age groups, educational stages, and sexes. Multiple linear and logistic regression analyses were conducted to identify factors associated with astigmatism.RESULTS:A total of 7 233 students aged 4-18 y were enrolled including 3 731 males, 3 502 females, with the mean age 10.13±4.18 y, astigmatism -0.76±0.82 D, and the detection rate(≤-1.00 D)was 29.23%. Both the degree and detection rate of astigmatism were correlated with age and educational stage, peaking in senior high school, with the most pronounced changes observed during primary school. Besides age, astigmatic refractive power was influenced by spherical equivalent(β=0.105, P<0.001), mean keratometry(β=-0.118, P<0.001), sex(with boys as the reference, girls: β=0.054, P<0.001), frequent sustained near work for 30-40 min(with “almost never” as the reference, β=-0.030, P=0.038), preterm birth(β=-0.023, P=0.044), maternal myopia(β=-0.028, P=0.020), and homework completion time on rest days(β=-0.035, P=0.041). The detection rate of astigmatism was associated with maternal myopia(OR=1.130, P=0.039), male sex(OR=0.773, P<0.001), shorter sleep duration on school days(OR=0.909, P=0.028), shorter sleep duration on rest days(OR=0.937, P=0.046), preterm birth(OR=1.382, P=0.012), frequent excessive head lowering(OR=1.216, P=0.045), homework completion time on rest days(OR=1.043, P=0.046), higher spherical equivalent(OR=0.891, P<0.001), and higher mean keratometry(OR=1.188, P<0.001).CONCLUSION:The degree and detection rate of astigmatism among children and adolescents from kindergarten to senior high school in Yangpu District, Shanghai are correlated with educational stage, and primary school may represent a critical period for astigmatism prevention and control. Male sex, maternal myopia, preterm birth, high-intensity near work, and insufficient sleep and other factors may be associated with the onset and progression of astigmatism. It is recommended that education and health departments strengthen visual health screening during primary school, while promoting behavioral interventions such as scientific eye-use habits and adequate sleep across different educational stages to delay the onset and progression of astigmatism.

Objective:To explore the longitudinal relationship between adolescents' future self-continuity and depression, providing insights into their future development.Methods:A total of 419 adolescents from a school in Shandong Province were selected, and two followed-up surveys were conducted at 6-month intervals in April (T1) and October (T2) of 2023 using the future self-continuity questionnaire and Beck depression inventory-Ⅱ. Cross-lagged analysis was performed using Mplus 8.0.Results:The scores of future self-continuity were 36.01±8.69 at baseline (T1) and 35.89±9.92 after six months (T2), while the scores of depression were 2.00(0, 14.00) and 1.00(0, 9.00), respectively. There was a negative correlation between future self-continuity and depression at both time points (T1: r=-0.195, T2: r=-0.239, both P<0.01). Adolescents' future self-continuity could predict depression six months later ( β=-0.098, P<0.01), and depression also could predict the level of future self-continuity six months later ( β=-0.114, P<0.01). Conclusion:There is an interactively influence effect between adolescents' future self-continuity and depression.While enhancing adolescents' future self-continuity level to alleviate depression, attention should also be paid attention to the impact of depression on their future self-continuity, which can help adolescents overcome the interference of depressive emotions and grow into a better future self.

AIM: To analyze the causes of blindness and low vision in patients with visual disability in Yangpu District of Shanghai from 2019 to 2022.METHODS:Cross-sectional study. A total of 1 604 patients who participated in the evaluation of visual disability in Shanghai Yangpu District Kongjiang Hospital, from April 2019 to December 2022 were selected for the study. The grade of visual disability and the main causes of blindness and low vision were determined by trained doctors.RESULTS:A total of 804 patients with visual disabilities were identified, with 87.31% aged 60 and above. The causes of visual disability were high myopic retinopathy(30.47%), age-related macular degeneration(23.26%), glaucoma(17.04%), and diabetic retinopathy(11.07%). Glaucoma(36.96%)is the leading cause of blindness.CONCLUSION: The majority of patients with visual disability are aged 60 years and above. More attention should be paid to the elderly population. Comprehensive prevention, treatment and rehabilitation measures should be applied in different diseases based on classification, so as to early reduce the occurrence of visual disability.
