    Early interruption of maternal bonding and social isolation are variables involved in social and emotional behavior, which can cause increased anxiety, especially in stressful situations. However, there is no research to explain the phenomenon of overeating anxiety disorder associated with these factors in an animal model and their effects on the morphology of the adrenal gland (AG), liver and spleen. Henceforth, the objective of this research was to determine the effects of early and late intake behavior in adrenal gland, liver and spleen morphology of Sprague-Dawley rats subjected to chronic stress during adulthood. We used 35 newborn female rats, maintained under standardized suckling and feeding conditions. The rats were randomized into 2 control groups (C1 and C2) and 3 experimental groups exposed to an early adverse experience (E1), late (E2) and early-late (E3) subsequently subjected to chronic intermittent stress in adulthood (C2, E1, E2 and E3). Intake behavior of groups and morphological changes of the left AG, the liver and spleen were evaluated by determining morphometric and stereological parameters for each organ. The early and late adverse experiences are factors that influence coping with a stressful situation favoring increased caloric intake and palatable food choice. The morphological features of the AG, the liver and spleen of rats can be affected by exposure to chronic stress, however, when individuals have undergone previous adverse experiences, these changes are more obvious.
