**Abstract**

Several studies, including the innovative 1998 ACE Study by CDC-Kaiser Permanente, have assessed the association among adulthood chronic disease and the prevalence of maladaptive, health-harming behaviors including: excessive alcohol use, tobacco use, physical inactivity, psychiatric illness including suicidal ideation or attempts, promiscuous sexual behavior (>50 sex partners), history of STI/STD and severe obesity (obesity (BMI > 35 kg/m2 )), subsequent to an individual's exposure to adverse childhood experiences (ACEs). Individuals that have encountered numerous instances of ACEs are almost twice as likely to die before the age of 75, demonstrating a dose-dependent relationship between the instances of ACEs and an increased morbidity/mortality in regard to chronic disease. This excerpt examines the contribution of ACEs to chronic disease and the consequential maladaptive behavior to said adversity, the consequential physiologic and biomolecular changes explained by the Biological Embedding of Childhood Adversity Model in addition to the implications of recounted ACEs on international health security in regard to concepts like conflict, displacement and food insecurity. The apparent association among adulthood chronic disease and ACEs demand changes that promote preventative processes as a means to address the implications these interconnections have on international health.
