Child abuse and physical health: A population-based study on physical health complaints among adolescents and young adults

Aims: To investigate whether adolescents and young adults with a history of child abuse had more physical health complaints compared to their unexposed peers. We also aimed to estimate associations between different child abuse types with physical health complaints and associations between the number of child abuse types and physical health complaints. Methods: This population-based telephone survey over two waves included 506 adolescents and young adults exposed to child abuse and 504 non-abused peers aged 16–33 years. We applied linear regression analyses to investigate associations between child abuse types and physical health complaints, unadjusted and mutually adjusted for co-occurring abuse, and to investigate how the number of child abuse types associated with physical health complaints. Results: Participants exposed to child abuse reported significantly more physical health complaints. The child abuse types strongly co-occurred. When adjusting for co-occurring child abuse, only sexual and emotional abuse were significantly associated with physical health complaints. Physical health complaints increased with the higher number of child abuse types experienced. Conclusions: Our findings suggest that exposure to abuse, particularly sexual and emotional, during childhood predicts physical health complaints in adolescence and early adulthood. In a public health perspective, early identification of child abuse may be beneficial in preventing physical health complaints later in life.
