Evaluation of a Simple Immunological Test (sIgA) During the RAAF survival Course.

摘要

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.
