Kiecoult-Glaser et al (1984) - Aim• To investigate the influence of stress on the immune system in medical students taking examinations at university.
Kiecoult-Glaser et al (1984) - Method• Blood samples taken from 75 medical students. First, a month before their examinations and second during the exams.• This was to compare h___ stress and l___ stress times.• Participants completed a questionnaire to assess things such as loneliness, unhappiness and stressful life events. (Why these things?)• The NK (Natural Killer – like T) cells were analysed. The higher the NK cells, the more efficient the immune system.
Kiecoult-Glaser et al (1984) - Findings• Blood samples taken during exams showed lower NK count than when taken the month before.• Questionnaires indicated that those reporting more stressful events had the lowest NK count.• This suggests that the immune system is suppressed by exams and therefore the students were more vulnerable to illness.• Also if they are experiencing a more stressful life, we are more vulnerable to the effect of external stressors.
