Characteristics and risk factors of Health-Related Risky behaviors in adolescents with Depression

To explore the characteristics and risk factors for health-related risky behaviours (HRRBs) in adolescents with depression. A total of 136 adolescents aged 12–18 years who met the diagnostic criteria for depression, and 272 healthy controls. All the subjects were assessed with the Adolescent Health-Related Risky Behavior Inventory (AHRBI), and the AHRBI scores of the two groups were compared with the Mann–Whitney U test. The depression group was assessed with the Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), Childhood Trauma Questionnaire (CTQ), Cognitive Emotion Regulation Questionnaire (CERQ), Egna Minnen av Barndoms Uppfostran (EMBU), and Family Adaptability and Cohesion Scale (FACES II-CV). Spearman correlation analysis and multiple linear regression were used to explore the risk factors for HRRBs in adolescents with depression. The AHRBI total score and five-factor scores of self-injury and suicide (SS), aggression and violence (AV), rule-breaking (RB), smoking and drinking (SD), and health-compromising behavior (HCB) in the depression group were higher than those in the control group. The severity of anxiety, catastrophizing, cognitive emotional regulation strategy (self-blame and blaming of others), the frequency of depression, physical neglect, and sexual abuse all increased the risk of HRRBs in adolescents with depression, and paternal emotional warmth and understanding had protective effects. First, depressed adolescents exhibited significantly more HRRBs than healthy adolescents. Second, there are many risk factors for HRRBs in adolescents with depression, and the risk factors for different types of HRRBs are also different.
