Children whoseparents and families are under ongoing stress have more fevers with illness than other children, research has shown.
The study, published in the Archives of Pediatric and Adolescent Medicine this month, followed 169 five to 10 year olds for three years and involved seven visits about six months apart.
Parents also completed surveys to assess family stress over the course of the study. It found children living with chronic stress in their families were sick more often.
The study authorssaid they hoped to build on the study to determine what types of parental and family stress lead to increased illness and what biological processes control susceptibility to infections.
they said: 'Once we understand these connections we can design interventions that lower family stress or help families to better manage stress in their interactions and lead to healthier kids.'
