Kids affected by relationship with caregiver

Two studies published in the November/December issue of Child Development show the biological effects stress has on children in these common situations.

The studies find bickering parents and poor caregiver relationships each increase levels of the stress hormone cortisol in children.

Long-term or frequent rises in cortisol can have negative health consequences.

Research with animals and people suggests that secure relationships help prevent cortisol rises in children.
