<p>Unintentional injuries are the leading cause of death for children under 5 years of age. While children of mothers who possess certain socio-demographic risk factors (i.e., low income, younger maternal age, mental health challenges, life stress) have higher rates of injury, little is known as to why. Few studies have investigated the potential influence that parental executive functioning (EF) may have on higher rates of injury in children. We investigated EF as a statistical moderator of the relationship between socio-demographic risk factors and frequency of childhood injuries. A diverse sample of first-time mothers (<i>N</i> = 56) of young children (&lt; 4 years) completed questionnaire measures and an EF task online. EF was found to moderate the relationship between maternal age and injury and, in specific circumstances, to moderate the conditional effect of social support, life stress, and mental health challenges on childhood injury. No relationship between income level and frequency of injury was found. Parental EF is an area for future research that may explain the higher rates of injury in vulnerable child populations. Implications for child injury prevention and intervention are discussed.</p>
