Objectives: A number of studies have shown dysregulation of the hypothalamus-pituitary-adrenal axis in alcoholics. The aim of the present study was to determine whether there are differences in salivary cortisol responses to a psychological stressor between nonalcoholic offspring from families with a history of alcoholism and those without a family history of alcoholism in Korea.
Methods: We studied 45 healthy social drinkers, who were medical students aged≥18 years. The participants completed a baseline assessment and, salivary cortisol levels were obtained. All subjects were exposed to almost 15 minutes of stress. Immediately following completion of the stress exposure, four additional salivary specimens were obtained for cortisol levels at 15 minute intervals. The subjects were divided into two groups those who reported a history of alcoholism in either parent(FHP, n=9) and those who reported no alcoholism in their family for three generations(FHN, n=30).
Results: A significant difference in salivary cortisol by family history group(p＜.001), and by time was discovered (p=.005) with a repeated-measures ANOVA. Basal salivary cortisol levels in FHP subjects were significantly higher than those in FHN subjects(p=.003). After stress exposure, salivary cortisol levels decreased significantly over time in the FHN group, whereas they did not in the FHP group.
Conclusion: FHP subjects had higher baseline salivary cortisol concentrations than those of FHN subjects and maintained the levels after stress. This finding suggests that social drinkers with a history of alcoholism in a parent have increased vulnerability to stress and difficulty coping with stress effectively.
