RESUMEN
Objective@#To explore the influencing factors for the primary and secondary school students with abnormal angle of trunk rotation for the prevention.@*Methods@#The students of Grade Four to Nine in Jiashan County of Zhejiang Province were selected by cluster sampling method. A self-designed questionnaire was used to collect social demographic data, diet behaviors, physical activities, reading and writing habits. The angle of trunk rotation was measured by scoliometer. Logistic regression model was used to investigate the influencing factors for abnormal angle of trunk rotation. @*Results@#This study included 2 942 schoolchildren, with 1 582 ( 53.78% ) boys and 1 360 ( 46.23% ) girls. The incidence rate of abnormal angle of trunk rotation was 7.82%. The incidence rate of abnormal angle of trunk rotation in girls was 10.74%, which was higher than 5.31% in boys ( P<0.05 ). Grade ( OR=1.485, 95%CI: 1.058-2.085 ), gender ( OR=2.084, 95%CI: 1.536-2.828 ), frequency of eating fresh vegetables in the past week ( OR=0.749, 95%CI: 0.633-0.887 ) and watching electronic screen in the dark ( OR=1.188, 95%CI: 1.002-1.408 ) were the influencing factors for abnormal angle of trunk rotation in primary and secondary school students. Grade ( OR=2.664, 95%CI: 1.481-4.791 ) and watching electronic screen in the dark ( OR=1.325, 95%CI: 1.030-1.704 ) were influencing factors for abnormal angle of trunk rotation in boys. Frequency of eating fresh vegetables in the past week ( OR=0.714, 95%CI: 0.574-0.887 ) and uncorrected eyesight less than 5.0 ( OR=1.795, 95%CI: 1.164-2.767 ) were influencing factors for abnormal angle of trunk rotation in girls. @*Conclusion@#The abnormal angle of trunk rotation in primary and secondary school students is related to gender, grade, reading and writing behaviors as well as diets; and the influencing factors are different in male and female students.
RESUMEN
Objective@#To investigate the prevalence and influencing factors of adolescent depression symptoms in Zhejiang, so as to provide reference for improving their mental health. @*Methods@#The middle school and university students in 11 cities of Zhejiang Province were selected by stratified cluster random sampling method. The depression symptoms of the adolescents were assessed by Center for Epidemiological Survey-Depression Scale ( CES-D ) and the influencing factors were analyzed by multivariate logistic regression model.@*Results@# A total of 25 855 students were investigated, and 25 614 ( 99.07% ) valid questionnaires were collected. The detection rate of depressive symptoms was 26.86%(6 879 cases). The detection rate of depressive symptoms in girls was 29.75%, which was higher than 24.12% in boys ( P<0.05). The detection rate of depressive symptoms in high school students was 31.74%, the highest compared with other grades. The multivariate regression analysis showed that female students ( OR=1.690, 95%CI: 1.592-1.794 ), resident students ( OR=1.071, 95%CI: 1.010-1.137 ) , internet addiction ( OR=2.948, 95%CI: 2.527-3.439 ) , attempt smoking ( OR=1.516, 95%CI: 1.359-1.690 ), drinking ( OR=1.624, 95%CI: 1.525-1.729 ), bullied in the past 30 days ( OR=3.143, 95%CI: 2.938-3.363 and having serious injuries within a year ( OR=1.369, 95%CI: 1.263-1.543 ) were associated with adolescents who had depressive symptoms.@*Conclusions@#The detection rate of depressive symptoms is relative 26.86% among adolescents of Zhejiang Province. The students who are female, live on campus, have internet addiction, have been bullied or seriously injured, smoke and drink are more likely to have depressive symptoms.
