A study conducted in Thailand reveals that nearly half of primary school children report experiencing Adverse Childhood Experiences (ACEs), which are linked to long-term health risks. The research, involving 399 students aged 6 to 12, found that 48.7% of participants experienced at least one ACE, with caregiver divorce or separation being the most common (33%). Other reported ACEs included neglect (9.3%) and domestic violence (8.3%). The study showed that children with four or more ACEs were at a significantly higher risk for behavioral problems, including internalizing issues, externalizing issues, and overall behavioral difficulties. However, no significant link was found between ACEs and physical or mental health conditions. The findings highlight the importance of early interventions and family support to mitigate the negative impacts of ACEs on children’s behavior and overall well-being. The researchers advocate for primary prevention strategies to assist families before adverse experiences occur.
