Objective:
To examine the effect of lifestyle behaviors on myopia among primary and middle school students in Yinzhou District, Ningbo City using latent class analysis, so as to provide insights into prevention of myopia among primary and middle school students.
Methods:
A total of 1 547 students were sampled from primary and middle schools in Yinzhou District using a stratified cluster sampling method. Myopia-associated lifestyle behaviors were collected using questionnaires, and visual acuity was tested. Myopia-associated lifestyle behaviors were subjected to latent class analysis among primary and middle school students, and the association between lifestyle behaviors and risk of myopia was examined using a logistic regression model.
Results:
A total of 1 547 questionnaires were allocated, and 1 494 valid questionnaires were recovered, with an effective recovery rate of 96.57%. There were 247 primary school students (16.53%), 452 junior high school students (30.25%), 532 senior high school students (35.61%) and 263 vocational high school students (17.60%), and 773 men (51.74%) and 721 women (48.26%). Latent class analysis showed that students' lifestyle behaviors were classified into three groups, including the healthy behavior group (37.68%), reading and writing fatigue group (42.64%), and video fatigue and poor diet group (19.68%), with myopia prevalence of 79.22%, 88.38% and 86.73%, respectively. Moderate myopia was predominant in the reading and writing fatigue group and video fatigue and poor diet group, and low myopia was predominant in the healthy behavior group. A higher risk of myopia was found in the reading and writing fatigue group (OR=1.996, 95%CI: 1.454-2.739) and video fatigue and poor diet group (OR=1.715, 95%CI: 1.157-2.543) than in the healthy behavior group.
Conclusions
Long reading and writing duration, insufficient exercise and sleep, long video watching duration, and high intake frequency of sugary drinks and fried foods may increase the risk of myopia in primary and middle school students in Yinzhou District. Targeted myopia interventions are required tailored to different categories of lifestyle behaviors.

Objective:
To analyze the association between latent class of health-risk behaviors and depressive symptoms among middle school students, so as to provide the evidence for the prevention and intervention of depressive symptoms among middle school students.
Methods:
Students in two junior high schools, two senior high schools and one vocational high school in Yinzhou District, Ningbo City, Zhejiang Province, were selected using a stratified multi-stage cluster sampling method. Demography and health-risk behaviors were collected using questionnaire surveys, depressive symptoms were investigated using the Center for Epidemiological Studies Depression-10 Scale, and latent class analysis was conducted for health-risk behaviors. The association between different latent classes and depressive symptoms was analyzed using a multivariable logistic regression model.
Results:
A total of 1 247 students were surveyed, including 641 boys (51.40%) and 606 girls (48.60%). There were 452 junior high school students (36.25%), 532 high school students (42.66%) and 263 vocational high school students (21.09%). Latent class analysis showed that health-risk behaviors in students were classified into three groups, namely healthy behavior group (52.93%), poor diet group (39.94%) and high-risk behavior group (7.14%), and the detection rates of depressive symptoms were 7.12%, 18.88% and 52.81%, respectively, with a statistically significant difference between groups (P<0.05). Multivariable logistic regression analysis showed that after adjusting for age, gender, native place, only child and living on campus, the poor diet group (OR=3.107, 95%CI: 2.086-4.627) and high-risk behavior group (OR=15.401, 95%CI: 9.031-26.262) had higher risks of depressive symptoms compared with the healthy behavior group.
Conclusion
Having high-risk behaviors and poor diet may increase the risk of developing depressive symptoms among middle school students.

Objective To evaluate the clinical application value of a novel immobilization system in total marrow irradiation ( TMI) with MVCT image. Methods From 2016 to 2017, a retrospective analysis of the setup errors of 22 patients receiving TMI in two groups ( twelve patients were immobilized with the novel immobilization system in group 1, ten patients were immobilized with the combinatorial immobilization devices in group 2) was performed in this study on Zhongnan Hospital of Wuhan University. Two-sample t-test was used to analyze the differences of setup errors and the consistency of setup between two groups. Results In group 1, the setup errors on left-right, superior-inferior, anterior-posterior and rotation directions were ( 1.06±0.79) , ( 1.34±0.66) , ( 2.45±1.48) mm and ( 0.63°±0.65°) for the head and neck position, ( 1.58±1.13) , ( 2.38±1.99) , ( 2.05± 1.68) mm and ( 0.31°± 0.32°) for the chest position, ( 1.67± 1.24) , ( 3.88±2.20) , ( 1.96± 1.32) mm and ( 0.48°± 0.53°) for the pelvis position, and ( 0.95± 0.73) , ( 1.99± 1.35) , ( 3.66±2.13) mm and ( 0.24°±0.31°) for the lower limb, respectively. In group 2, the setup errors were ( 2.59±2.58) , ( 3.28±1.85) , ( 3.71±2.43) mm and ( 1.15°±1.18°) for the head and neck position, ( 4.38±3.69) , ( 5.64±3.78) , ( 2.72± 1.91) mm and ( 1.55°± 0.86°) for the chest position, ( 4.14± 2.97) , ( 6.97±3.68) , ( 2.21±2.26) mm and ( 1.23°±0.74°) for the pelvis position, ( 2.28± 1.15) , ( 5.97± 3.00) , ( 3.44±1.93) mm and ( 1.09°±0.94°) for the lower limb, respectively. The setup errors significantly differed between two groups on the left-right, superior-inferior and rotation directions for all positions ( all P<0.05) . The setup consistency significantly differed between two groups on the left-right, superior-inferior and rotation directions for the chest and pelvis positions ( all P<0.05) . Conclusion The novel immobilization system can significantly improve the setup accuracy and setup consistency, and enhance the precision of treatment for patients.
