Objective: To explore the association of outdoor activity time and sleep duration with screening myopia in primary school students, so as to provide strategies for myopia prevention. Methods: Through a convenience sampling method, a survey was conducted among 4 248 primary school students aged 7-13 years from three primary schools in Xihu District, Nanchang City, Jiangxi Province from May to July, 2023. The average daily outdoor activity time and sleep duration on both weekdays and weekends were investigated in primary school students by using a self designed questionnaire. Uncorrected visual acuity tests and non cycloplegic autorefraction were measured by professional optometrists. Inter group comparisons were conducted using the Chi square test. Logistic regression model was used to analyze the association of outdoor activity time and sleep duration with screening myopia. Results: The detection rate of screening myopia in primary school students was 33.6%, with the rate in boys (32.0%) lower than that in girls (35.3%), and the difference was statistically significant ( χ 2=5.11, P =0.02). The analysis results of Logistic regression showed that after adjusting for factors such as gender, grade and parental education level, both average daily outdoor activity time ＜2 h on both weekdays and weekends ( OR =1.27, 95% CI =1.11-1.46) and sleep duration <10 h ( OR =1.17, 95% CI =1.01- 1.35 ), as well as their combined effect ( OR =1.57, 95% CI =1.25-1.98), were associated with an increased risk of screening myopia in primary school students(all P <0.05). Subgroup analysis results indicated that compared to boys ( OR =1.46, 95% CI = 1.07 -1.99), girls( OR =1.73, 95% CI =1.22-2.44) with insufficient outdoor activity time and sleep duration had a higher risk of screening myopia(both P <0.05). Conclusions There is a negative correlation of outdoor activity time and sleep duration with screening myopia in primary school students. Outdoor activity time and extending sleep duration should be increased to reduce the risk of myopia in primary school students.

Objective:To investigate the iodine nutrition status of children aged 8-10 and pregnant women in Longxi County, Gansu Province.Methods:Descriptive epidemiological method was used to analyze the water iodine monitoring data in 2017 and the iodine deficiency disorders monitoring data from 2017 to 2023 in Longxi County (sourced from the Institute for Endemic Disease Prevention and Control of Gansu Provincial Center for Disease Control and Prevention), including the data of water iodine, salt iodine and urinary iodine levels of children aged 8 to 10 and pregnant women, and children's thyroid B-mode ultrasound examination results. Iodine nutrition was evaluated based on the "Guidelines for Monitoring Salt Iodization Projects and Determining Population Iodine Nutrition".Results:In 2017, a total of 85 water samples were collected, with a median iodine level of 1.6 μg/L, ranging from 0.2 to 10.9 μg/L. Except for one water sample with an iodine level of 10.9 μg/L, the iodine level of all other water samples was less than 10 μg/L. From 2017 to 2023, a total of 1 585 children and 718 pregnant women were monitored. The urinary iodine levels were 190.8 (120.2, 252.2), 137.0 (79.8, 195.8) μg/L, respectively. The coverage rate of iodized salt in Longxi County from 2017 to 2023 ranged from 99.4% to 100%, the consumption rate of qualified iodized salt ranged from 61.8% to 93.0%, and the qualified rate of iodized salt ranged from 62.1% to 93.0%. The median range of the urinary iodine for children in Longxi County was 125.9 to 228.5 μg/L. There was a statistically significant difference in the urinary iodine levels among children from different years ( P < 0.001). There was no statistically significant difference in urinary iodine levels among children of different genders and ages ( P > 0.05). There were statistically significant differences in the composition ratio of iodine nutrition status among children of different years, genders, and ages ( P < 0.05). The median range of urinary iodine in pregnant women was 121.0-180.5 μg/L. Except for 2017, the median urinary iodine of pregnant women in all other years was less than 150 μg/L. There were statistically significant differences in the urinary iodine levels and composition ratio of iodine nutrition status among pregnant women in different years ( P < 0.001). There was no statistically significant difference ( P > 0.05) in the urinary iodine levels and composition ratio of iodine nutrition status among pregnant women during different stages of pregnancy, and all pregnant women were iodine deficient in the early, middle, and late stages (median urinary iodine < 150 μg/L). Six hundred and sixty-five children underwent B-mode ultrasound examination, with a goiter rate ranging from 0 to 5.0%. Conclusion:From 2017 to 2023, the iodine nutrition of children aged 8 to 10 in Longxi County is in an appropriate state, while the iodine nutrition of pregnant women is in a deficiency state.
