Abstract
INTRODUCTION: Depression is one of the mental illnesses that affect adolescents worldwide. This study analysed the factors associated with depressive symptoms among adolescents in Indonesia. METHOD: A quantitative cross-sectional study was conducted using secondary data from the Indonesian Family Life Survey 2014. The sample included 3,603 adolescents aged 10-19 years. Data were analysed using logistic regression statistical tests. RESULTS: Of the adolescents, 29.1% had depressive symptoms. The bivariate analysis showed that sex, region, economic status, chronic illness history, sleep quality, smoking habit, and personality type were associated with a higher probability of depressive symptoms among the adolescents. CONCLUSION: A history of chronic diseases contributes the most to the occurrence of depressive symptoms among adolescents. To reduce the prevalence of chronic diseases associated with depression, the Indonesian government must make preventive efforts through early detection among young people.
