Physical health and emotional and behavioral problems in maltreated children according to family economic status: Health problems of maltreated children in Korea

Low family income is a risk factor for child maltreatment. However, there has been no comparative study on the association between child maltreatment and family income. The objective of this study was to investigate the physical health and emotional and behavioral problems of maltreated children according to the economic status of their family. Cross-sectional nationwide study Data from 2012 to 2014 was extracted from the Korean National Child Abuse Registry (age <18 years) operated by the National Child Protection Agency (NCPA). Demographic characteristics and 34 physical health and emotional/behavioral problems of maltreated children were compared by family economic status. Family economic status was classified into 2 groups: families receiving the National Basic Livelihood Guarantee (NBLG) and those not receiving the guarantee (non-NBLG group). A total of 17,128 children were registered in the system. Mean age was 9.3 years (SD 4.8 years), 44.4% were females, and 29.2% were in the NBLG group. Poor hygiene, anxiety, and attention deficit were frequently reported physical and emotional health problems. Common behavioral problems included running away, rebelliousness/impulsivity/aggressiveness, maladjustment in school, learning problems at school, and frequent unauthorized absenteeism and truancy. Physical health problems (7 of 8 items) occurred more often in the NBLG group, and behavioral problems (6 of 17 items) occurred more often in the non-NBLG group. Children in Korea who are maltreated have different physical health, emotional, and behavioral problems depending on their family income level. These results can be useful in approaching the recognition of and interventions for child maltreatment.
