Background. Adverse Childhood Experiences (ACEs) refer to a semantic field of negative childhood events that, in conjunction with insufficient personal, family, or contextual coping resources, have the potential of becoming traumatic.

Objective. To assess the prevalence of Adverse Childhood Experiences (ACEs) and their association with sociodemographic variables and physical and mental illnesses in a Mexican sample.

  Design. A cross-sectional design was used. The sample included 917 Mexican adults who responded to the Adverse Childhood Experiences International Questionnaire (ACE-IQ). Most of the participants were female (79.3%) with an average age of 37 years, a monthly income between 500 and 2,500 USD (59.2%), had completed university education (45.6%) and were married or in a common-law marriage (53.1%). Data was collected through Google Forms, and the link to the form was shared through electronic social networks.

  Results. A total of 48.3% of the participants presented seven to nine types of ACEs. Among their responses, the most prevalent categories were emotional neglect (95.1%), family violence (83.3%), and emotional abuse (78.6%). A significant association was found between the number of ACEs and the mental illness diagnosis (x²(20) = 15.16; p < .001). Women were found to report more experiences of sexual abuse (z = -6.62, p < .001), whereas men reported more experiences of community violence (z = -4.27, p < .001) and collective violence (z = -3.94, p < .001).

  Conclusions. The prevalence of ACEs in the Mexican population is high. However, men and women reported differences in certain types of ACEs. It was found that people with a diagnosis and family history of mental illnesses presented a higher number of ACE categories.
