"The aim of the study was to look at how children responded to the experience of starting school and how they had adapted after six months of the start of their first term. In total, one hundred and five children (53 boys and 52 girls) and one of their parents signed up for the study. In addition, 76 teachers agreed to take part and provide information relating to adjustment to school. The first issue that we explored was that of physical stress responses of children before, during and after starting school, which we measured by collecting saliva samples in the morning and evening at specific time points throughout the study. Secondly, we set out to look at the relationship between these responses and children’s behaviour, on their ability to learning and on their physical health (common cold and flu)"
