The epidemiological characteristics of depressive symptoms in the left-behind children and adolescents of Chongqing in China

Abstract

ObjectiveTo assess the prevalence rate of depressive symptoms in left-behind participants aged 7–17 years and to explore the associated socio-demographic and communication factors. MethodsParticipants were 4857 left-behind children and adolescents in Chongqing. They were screened for depressive symptoms using a 27-item Children׳s Depression Inventory (CDI) and social-demographic variables were evaluated with a structured scale. Uncorrected Pearson chi-square test and logistic regression were applied to analyzing the data. ResultsThe total prevalence rate of depressive symptoms was 24.8%. Significant difference was found in the prevalence rate of depressive symptoms among groups of different income, grade, age, left-behind subtypes, and different frequency, ways and topics of parent-child communication. We found that the risk factors for depression were absence of parents, low frequency of parent-child communication, and communication by letter or about sensitive topics. The grade group 2–3 and age group 16–17 were at a higher risk of depression than all other grade and age subgroups. The protective factors for depression were high-income, high frequency of parent-child communication, communication by telephone or about such topic as learning experience, school life, and feelings. LimitationsSelf-report bias and cross-sectional nature of the sampling are major limitations of this study. ConclusionsThe prevalence rate of depressive symptoms among left-behind children and adolescents in Chongqing is much higher than previously reported prevalence in other regions of China. The risk and protective factors for depression among left-behind children and adolescents are worthy of public attention.
