ABSTRACT
Objective@#To explore the related factors of myopia among children and adolescents in Yunnan Province, and to predict and evaluate the influencing factors, so as to provide a scientific theoretical basis for the prevention and control of myopia.@*Methods@#From March 9 to 14, 2023, 848 students from 6 primary and secondary schools in Dali and Lijiang of Yunnan Province were selected by multi stage stratified random cluster sampling method for visual acuity detection and questionnaire survey on myopia related factors. Multivariate Logistic regression analysis was used to establish a Nomogram prediction model for the selected influencing factors.@*Results@#The overall myopia rate of the respondents was 68.3%, the myopia rate of boys (63.4%) was lower than that of girls (72.9%), and the myopia rate of primary school students (46.7%) was lower than that of junior high school students (81.1%), and the difference was statistically significant（ χ 2=8.71, 108.07, P <0.05). Daily eye exercises, activities outside the teaching building during recess, having daily sleep time of 7-9 and >9 h, having both parents without myopia were negatively correlated with the occurrence of myopia in children and adolescents in Yunnan Province ( OR=0.64, 0.63, 0.56, 0.28, 0.48, P < 0.05 ). The reading and writing time after school ≥3 h per day and parents unrestricted time to play video games were positively correlated with myopia ( OR=1.94, 1.78, P <0.05). Based on the influencing factors, a Nomogram prediction model was established to quantitatively evaluate the risk of myopia. The results showed that greater risk for myopia was associated with sleep duration, parental history of myopia, and the time spent reading and writing after school every day.@*Conclusion@#Both genetic factors and environmental factors are related to myopia in children and adolescents. The prediction model of nomogram is beneficial for screening high risk factors of myopia and taking corresponding prevention and treatment measures.
ABSTRACT
Objective:To summarize the classification of etiology, age of onset, prognosis of children with convulsion, so as to provide experience guidance for clinicians engaged in pediatric emergency department.Methods:The clinical data of children with convulsions received in the emergency department of Children′s Hospital Affiliated to Kunming Medical University from January 2015 to December 2018 were analyzed retrospectively.Results:During the four-year period, 2 957 children with convulsion were received in the emergency department, accounting for 22.20% of the total number of critically ill children in the observation room of the emergency department, and the ratio of male to female was 1.7∶1.The etiological diagnosis of convulsion in emergency are as follows: febrile convulsion(733 cases, 24.79%), central nervous system infection(477 cases, 16.13%), unexplained convulsion(476 cases, 16.09%), epilepsy(371 cases, 12.55%), benign infantile convulsions with mild gastroenteritis(240 cases, 8.12%). The age of onset: 8.25% were in neonatal period, 33.99% were in infant, 34.87% were in toddler′s age, 12.17% were in preschool age, 7.88% were in school age and 2.84% were in adolescence.Destination statistics: 72.00% were admitted to hospital for further treatment, 13.29% were transferred to neurology clinic, 7.85% to pediatric clinic, 1.66% to rehabilitation clinic, and 0.17% died.Inpatient department: 43.64% were admitted to department of neurology, 17.52% to pediatric intensive care unit, 13.71% to department of neonatology, 12.64% to department of gastroenterology and 2.72% to department of rehabilitation.Conclusion:Febrile convulsion is the main cause of convulsion in children who were received emergency treatment in our hospital.Most of the convulsion cases are from birth to preschool age, and the prognosis is good after active treatment.
