| Background: Depressive disorders are a major public health problem in developed and developing countries.
Recently, several risk factors have been described for depressive disorders in children and adolescents. The aim
of the present study was to identify the main risk factors that can affect the incidence of depression in Iranian
children and adolescents.
Methods: A total of 30,546 children and adolescents (between 6 and 18 years of age) participated in a crosssectional
study to identify the predictors of depressive disorders. Depressive disorders were assessed using the
Persian version of the Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS-PL). In addition, a
demographic characteristics questionnaire was completed by parents of the participants. The data was analyzed
using the SPSS
software via performing the descriptive analysis and the multiple logistic regression analysis
methods. P-values less than 0.05 were considered statistically significant.
Results: Results showed that a higher age (15–18), being female, and the father's unemployment were associated
with an increased odds ratio for depressive disorders. The age of 10–14 (OR =2.1; 95% CI, 1.57–2.81), the age
of 15–18 (OR =4.44; 95% CI, 3.38–5.83), female gender (OR =1.44; 95% CI, 1.2–1.73) and the father's unemployment
(OR =1.59; 95% CI, 1.01–2.5) were significant positive predictors, whereas, the mother's job (as a
housewife) (OR =0.66; 95% CI, 0.45–0.96) and a history of psychiatric hospitalization of the father and mother
(OR =0.34; 95% CI, 0.15–0.78 and OR =0.34; 95% CI, 0.14–0.84) were negative predictors for depressive
symptoms.
Conclusion: Depressive symptoms are common in children and adolescents and are correlated with age and
gender. The assessment of the prevalence of psychiatric disorders, especially the depressive disorders and their
comorbidities, may help to prevent mood disorders in children and adolescents.
