Objective:

To investigate the association between childhood maltreatment and the likelihood of developing physical and mental disorders in adulthood, as well as adult multimorbidity.

Approach:

• Study Design: A longitudinal study using population-based electronic health records in Hong Kong, following individuals with and without a confirmed history of childhood maltreatment from January 1, 2001, to December 31, 2024.
• Data Analysis: Cox proportional hazards regression models were employed to examine associations between childhood maltreatment and 16 adult diagnostic categories, adjusted for age, gender, and socioeconomic status.
• Multimorbidity Assessment: The study assessed simple, complex, and mental health multimorbidity, excluding infections and injuries.

Key Findings:

• Child maltreatment is associated with an increased risk of chronic physical health conditions in adulthood, including cardiovascular disease and diabetes.
• There is a four-fold increased risk of neurodivergent and psychiatric disorders linked to substantiated child maltreatment.
• Childhood maltreatment may lead to increased adult multimorbidity, defined as the coexistence of multiple health conditions.

Interpretation:

The findings suggest that childhood maltreatment has significant long-term health implications, affecting both physical and mental health outcomes in adulthood.

Limitations:

• Estimates of child maltreatment prevalence may be affected by recall bias and underreporting.
• Electronic health records may underidentify milder cases of maltreatment.

Conclusion:

Understanding the long-term health consequences of childhood maltreatment is crucial for developing effective prevention and intervention strategies.
