Child adversity has a negative impact on child and adult health. The present study aimed to determine whether adverse family experiences (AFEs) were associated with use of preventive health care (PHC) among children and whether insurance status affected this association. This study examined data from the 2011-2012 National Survey of Children's Health (N = 88,849) and included responses for children ages zero to 17 years. Logistic regression models were used to estimate odds of using PHC from AFEs. Results were stratified by insurance status and confounders were accounted for. Among the entire sample and the insured, most AFEs were not associated with use of PHC. Among the uninsured, several AFEs-lived with parents or guardians who were separated, lived with parent or guardian who was incarcerated, witnessing or experiencing violence in the household, and living with anyone who had substance abuse problems-and the sum of AFEs were associated with increased use of PHC. Findings are consistent with newer research showing that some disadvantage or adversity is associated with more optimal use of PHC. In addition, uninsured children with a history of AFEs would benefit from insurance, given their increased use of PHC.
