Socioeconomic Disadvantage among Adolescents: Associations between Having Relatives with Severe Health Conditions, Parental Work Status, and Poor Mental Health

Psychosocial risk factors, such as socioeconomic disadvantage and having close relatives with severe health conditions (RSHCs), may negatively impact an adolescent’s life. This study aimed to investigate the associations between adolescent experiences with RSHCs (no, one or several RSHCs), parental working status (PWS) (both parents working (both PW) or having ≥1 parent not working (≥1 PNW)) and the composite variable of RSCHs/PWS in relation to self-reported poor mental health. In 2020, population-based data on 15–18-year-olds (n = 3509) were collected from schools in Sörmland, Sweden. Relationships between the composite variable of RSCHs/PW and poor mental health were determined through logistic regression analyses in three different models. Odds ratios (ORs) are separately reported for girls and boys. Girls reporting several RSHCs/≥1 PNW displayed an OR of 5.05 (95% CI 2.82–9.04) in comparison with the reference group with no RSCHs/both PW when adjusting for grade and ethnicity. The corresponding OR for boys was 2.26 (95% CI 1.46–3.49). Further adjustments for protective factors for mental health attenuated the associations with poor mental health. In conclusion, adolescents with RSHC experiences in combination with parental unemployment are at increased risk of developing their own poor mental health, making this group particularly vulnerable.
