Caregivers in Childcare can Affect Kids' Stress Levels

Children’s relationships with their caregivers play a significant role in controlling their stress levels, according to a new study.

The study by researchers at Washington State University, Auburn University, the Washington State Department of Early Learning, and the Pennsylvania State University, was aimed to determine how the level of the stress hormone cortisol varies in children in full-day childcare.

It is believed that cortisol, the primary stress hormone in humans, tends to be at its highest levels in the early morning and gradually declines over the course of the day.

However, recent research has found that many preschoolers in full-day child care have increases in cortisol from morning to afternoon.

The study was conducted on 191 preschoolers attending 12 child care centers in a small southeastern U.S. community to determine if the quality of teacher-child relationships could predict increases in cortisol in the children.

The study found that children in classrooms with closer to 10 children were more likely to show cortisol decreases from morning to afternoon.

On the other hand, children in classrooms with closer to 20 children tended to show greater increases in cortisol across the day.

Also, kids with more clingy relationships with their teachers showed greater rises in cortisol from morning to afternoon, and children with more conflicted relationships with their teachers showed greater cortisol boosts during a one-on-one session with their teachers.

Conflicted relationships were said to occur when teachers tried to control resistant children, when children perceived their teachers as unfriendly, or when teachers or children reported that the teachers found the interaction frustrating.

Depression is one of the most common mental disorders affecting approximately 340 million people in the world. No one is immune from depression - it occurs in people of all social classes, all countries and all cultural settings.

Scientists believe that the unusual increase of cortisol levels is of potential concern because long-term or frequent elevations in cortisol can have negative health consequences.

In their research with animals and human children, scientists observed that secure relationships with parents protect children from rises in cortisol in stressful situations.

In the study, teachers were given a questionnaire describing their relationships with the children in their care on and children talked about their relationships with their teachers in interviews.

Researchers also collected saliva samples from the children in classrooms to determine changes in their cortisol levels from morning to afternoon. They also collected saliva outside of class before and after a series of mildly difficult tasks designed to look like challenges the children might experience in the classroom and before and after a non-challenging interaction with the teacher.

The study is appearing in the November/December 2008 issue of Child Development.
