Stressful times during your teenage years exact a physical toll that can have implications for health during adulthood.
In a study teens who self-reported various negative interpersonal interactions, such stress was associated with higher levels of an inflammatory marker called C-reactive protein, or CRP. CRP has been identified as an indicator for the later development of cardiovascular disease.
The study looked at a total of 69 adolescents who completed a daily diary checklist each night for 14 days. In it, they reported any experiences of negative interpersonal interaction with family, peers or school personnel. Blood samples were obtained an average of eight months later and assayed for circulating levels of the CRP protein.
The researchers found that daily interpersonal stress experienced during the high school years was associated with elevated levels of inflammation, as measured by higher levels of CRP, even among normal, healthy teens.
