A simple marker of immune function, salivary immunoglobulin A sigA, was evaluated as a potential indicator of stress during the RAAF Survival School courses conducted in November 1999. Twenty-seven males and two females with an average age of 26 years participated in the study by keeping a food diary, collecting saliva samples and recording their health problems daily checklist and level of anxiety State-Trait Anxiety Inventory. Participants height and weight changes were also recorded. Dietary restriction, consumption of alcohol, loss of weight and negative emotions were all shown to have a negative effect on sigA. Salivary IgA was shown to be a useful marker of the severity of stresses encountered during the survival course.
