Effects of chronic psychosocial stress on body weight gain and adrenal weight. a Chronic social defeat reduced body weight gain in stressed rats compared to control. Weekly data are expressed as percentages of body weight at the beginning of the experiment (mean ± SEM); **P < 0.01, ***P < 0.001 significant difference to control as determined by two-way repeated measures ANOVA with Bonferroni’s post hoc test. b Stress also caused a significant increase in adrenal gland weight; **P < 0.01, significant difference between all controls (including control CIT) and all stressed animals (including stress CIT) determined with the t test.
