ABSTRACT

Abstract@#Objective To investigate the prevalence and influencing factors of depressive symptoms among primary and middle school students in Xihu District, Hangzhou City, so as to provide insights into depression control among primary and middle school students. @*Methods@# Students were sampled from two primary schools, two junior high schools, two ordinary high schools and one vocational high school in Xihu District using a stratified cluster random sampling method from September to November, 2021. Participants' demographics, diet, exercise, sleep and campus bullying were collected using questionnaire surveys. The depressive symptoms were evaluated using the Chinese version of the Center for Epidemiologic Studies-Depression Scale (CES-D), and factors affecting the depressive symptoms were identified among primary and middle school students using a multivariable logistic regression model.@* Results@# A total of 1 518 students were investigated, including 518 primary school students (34.12%), 363 junior high school students (23.91%), 463 ordinary high school students (30.50%) and 174 vocational high school students (11.46%). Of all participants, there were 805 males (53.03%). The prevalence of depressive symptoms was 38.87% among the participants, and was 36.10%, 42.42%, 42.33% and 30.46% among primary school, junior high school, ordinary high school and vocational high school students, respectively. The multivariable logistic regression analysis showed that gender (OR=1.601, 95%CI: 1.289-1.989), type of school (junior high school, OR=1.299, 95%CI: 0.974-1.734; ordinary high school, OR=1.351, 95%CI: 1.025-1.780; vocational high school, OR=0.862, 95%CI: 0.585-1.272), frequency of fresh vegetable intake (less than once daily, OR=0.454, 95%CI: 0.304-0.679; once and more daily, OR=0.359, 95%CI: 0.235-0.548), duration spent on the internet (0.5 to 1 h daily, OR=1.447, 95%CI: 1.044-2.006; 1 h and longer daily, OR=1.456, 95%CI: 1.072-1.978), sufficient sleep (OR=0.525, 95%CI: 0.371-0.744), suffering from campus bullying (OR=1.992, 95%CI: 1.491-2.661) were associated with the development of depressive symptoms. @*Conclusions@# The prevalence of depressive symptoms is high among primary and middle school students in Xihu District.
