Objective: To evaluate the frequency of Adverse Childhood Experiences (ACEs) and the sociodemographic characteristics of the population with chronic disease. Methodology: Cross-sectional descriptive study that was conducted with 121 patients over age 18 with non-communicable, chronic diseases that sought internal medicine outpatient services at Fundación Valle del Lili from September to December of 2015. Validated scales to assess ACEs and other clinical variables of interest were applied to patients. Descriptive analysis of the data was conducted. Results: Of the participants, 69.4% was female; the median age was 62 years, with an IQR of 50 to 72 years. It was found that 64% of those surveyed presented at least one type of ACE, and 23% presented four or more ACEs, while physical abuse and parental separation were the most frequent (32% and 23%, respectively). Conclusions: Adverse Childhood Experiences are prevalent events in our population; however, such events have not received the attention needed. Further studies are warranted to measure the short- and long-term actual impact, with the respective implications for our health system.
