RESUMEN
AIM: To understand the status of poor vision and analyze the main influencing factors among primary and secondary school students in a division of the Xinjiang Production and Construction Corps, and provide a scientific basis for prevention and control of poor vision.METHODS: A total of 12 primary and secondary schools in a divisional urban district and regiment field of the Xinjiang Production and Construction Corps were chosen using stratified cluster random sampling from August to October 2020. A total of 2 982 primary and secondary school students were selected for visual inspections and questionnaires. Logistic regression analysis was used to explore the influencing factors of poor vision.RESULTS: The rate of poor vision was 65.66% among 2 982 primary and secondary school students in the division of the Xinjiang Production and Construction Corps, with the majority severe poor vision. Furthermore, the rates of poor vision were higher in girls(70.17%)than that in boys(61.47%)(χ2=4.993, P<0.001)and the urban area(70.03%)were higher than the rural area(58.96%)(χ2=38.680, P<0.001)and the Han nationality students(66.83%)were higher than Uyghur students(52.82%)(χ2=19.772, P<0.001). The risk of poor vision increased with age(χ2trend =300.144, P<0.001), and by the age group ≥18 years old, the rate of poor vision reached 80.47%. The results of the multivariate analysis showed that the women, the age≥13 years old, writing and reading duration every day ≥2h, cram school on weekends and presence of myopia in parents increases the risk of poor vision, increase the outdoor exercise time, sleep time ≥8h, and do eye exercises every day can reduce the occurrence of poor vision.CONCLUSION: Poor vision rate of primary and secondary school students in the division of the Xinjiang Production and Construction Corps is higher than that of many regions in the country. Girls with the age(≥13 years old)whose parents are myopic should receive special attention. Increasing outdoor exercise time, doing eye exercises every day, and keeping your eyes more than one foot away from books when reading and writing is effective in preventing poor vision.

RESUMEN
Objective To study the fundus diseases that primary and middle school students may be susceptible to suffer, and to understand the prevalence rate and constituent ratio of these diseases. Methods A total of 9 504 students were examined from November 2015 to February 2017 to find out their ocular fundus conditions. They were from all the primary and secondary schools directly subordinate to Dagang Oilfield headquarters. Among the 9 504 participants 4 998 were male and 4 506 were female,with the age span of 5 to 23 and the average age of(13.40±3.41).Our medical examination included uncorrected visual acuity examination and fundus oculi photography. The distribution of fundus diseases was analyzed,including gender,vision acuity and age composition of patients with major diseases. Results Among the 9 504 students,4 314 had emmetropic eyes,and 5 190 had refractive errors.A total of 9 126 out of the 9 504 examined students had normal ocular fundus(96.02%),while those with abnormal ocular fundus accounted for 378(3.98%).The main types of abnormal ocular fundus included the tessellation fundus 354 (3.72%), followed by the large depression of optic disk 16 (0.17%). Among all the 354 cases with tessellation fundus, 179 were male and 175 were female. There were 257 students whose visual acuity≤0.3/0.3,and the prevalence was higher in 17-19 years old students(5.86%).Conclusion It has been revealed in this epidemiological survey that the main abnormal ocular fundus of primary and middle school students in Dagang is tessellation fundus.Most of the tessellation fundus are caused by middle and high myopia,and very few are found in emmetropic students. It has also been found that the incidence of tessellation fundus increases significantly with the increase of age. The large depression of optic disk ranks the second in the abnormal ocular fundus, which is mostly physiological.

RESUMO Objetivo verificar a correlação entre tempo de permanência semanal na escola, e o desempenho de crianças com Transtorno do Espectro do Autismo em teste de inteligência não verbal e em habilidades comunicativas e de comportamento. Métodos Participaram deste estudo 44 crianças e adolescentes, com idade entre 6 e 12 anos. Todos os participantes estão matriculados em escolas regulares. Resultados Dos 44 participantes, 20 não responderam ao teste de inteligência não verbal; assim, eles foram divididos em dois grupos: - Grupo A: 24 participantes avaliados quanto a desempenho em inteligência não verbal e habilidades comunicativas e de comportamento e Grupo B, com 20 participantes avaliados quanto às habilidades comunicativas e de comportamento. Os resultados mostraram, no Grupo A, correlação positiva significativa entre a frequência escolar e a inteligência não verbal, e correlação negativa significativa entre frequência escolar e as inabilidades em linguagem expressiva e pragmática/social. No que diz respeito ao Grupo B, houve tendência a correlações negativas em todas as relações, mas significância apenas com relação às inabilidades pragmática/social. Conclusão De forma geral os resultados de ambos os grupos indicam que crianças com melhores resultados em inteligência não verbal e melhores habilidades de comunicação e comportamento tendem a permanecer mais tempo na escola por semana.
ABSTRACT Purpose Verify the association between the time spent at school per week and the performance of children and adolescents with autism spectrum disorders in non-verbal intelligence test and communicative and behavioral abilities. Methods Participants were 44 children and adolescents aged 6 to 12 years. All participants were enrolled in regular schools. Results Of the 44 participants, 20 did not respond to the non-verbal intelligence test. Therefore, the participants were divided into two groups: Group 1 was composed of 24 participants who were assessed in non-verbal intelligence, behavior and communication abilities; Group B comprised 20 participants who were assessed in communication and behavior abilities. Results for Group A showed significant positive correlation between the time spent at school per week and non-verbal intelligence, and significant negative correlation regarding impairments in expressive language and social/pragmatic abilities. Results for Group B presented a tendency to negative correlations in all associations, with significant correlation only with respect to social pragmatics. Conclusion The overall results for both groups indicate that children with higher non-verbal intelligence scores and better communication and behavior abilities tend to spend more time at school per week.
