Influencing factors for abnormality of the angle of trunk rotation in primary and secondary school students / 预防医学

ABSTRACT

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.
