Research published by Duke University researchers has found a strong link between higher stress in children and adverse health conditions for them later in life. Appearing in the journal Proceedings of the National Academy of Sciences, the study<\/a> used measurable metrics of health over time to create a more quantitative view of how stress early in life affects health.<\/p>\n “We’ve had an idea for a long time, since the ’80s at least, that when children have adversity in their lives, it affects how their bodies work, not just psychologically, but also physiologically. It gets underneath the skin, and it becomes embodied in the way your body handles stress,” said co-author Herman Pontzer, Duke professor of evolutionary anthropology and global health.<\/p>\n Researchers focused on allostatic load<\/a> (AL), which refers to the wear and tear on the body because of chronic stress. The researchers “tested associations between childhood AL and adult cardiometabolic health,” relying on biomarkers that included antibodies of C-reactive protein, which is a marker of inflammation in the body; and the Epstein-Barr virus, which is common and highly contagious; body mass index; and blood pressure<\/a>.<\/p>\n Analysis by lead author Elena Hinz, a Ph.D. student in the Pontzer Lab at Duke, showed that a child’s stress levels, in children as young as 9 to 11 years old, is an indicator of their cardio and metabolic health in adulthood.<\/p>\n Usually, researchers ask adults to remember their stress. Hinz and her fellow researchers used a big study that collected quantitative\u2014not just qualitative\u2014samples over time.<\/p>\n The paper’s authors reviewed data from the Great Smoky Mountains Study (GSMS), a longitudinal study of child psychiatric disorders<\/a> that began in 1992\u2014and continues today\u2014to determine the need for mental health services.<\/p>\n Hinz, who grew up in a rural community<\/a> in East Tennessee, said her own coming-of-age experiences spurred her interest in childhood stress.<\/p>\n “I’m from the rural South and kind of have this idea of what stress looks like in that environment, in terms of childhood adversity and dietary stress and the physical environment<\/a> that kids are in,” said Hinz.<\/p>\n Hinz said humans combat acute stress through a fight or flight response: “Your body collectively reacts by increasing your heart rate and blood pressure when you are experiencing a stressful situation,” she explained. “Those and other responses help you deal with that stress, but it’s not good to always be in that state. I’m interested in what happens when that doesn’t really subside.”<\/p>\n Poverty is at the crux of the study, which indicates a stable, financially secure home is essential for a healthy childhood free of chronic stress<\/a>.<\/p>\n “Children, eight, nine and ten years old\u2014what’s happening to them seems to be predictive of blood pressure,” said Pontzer about early life stress.<\/p>\n “What helps is education and job training<\/a> and all of the stuff that gets communities out of poverty. That gets people the help they need when they need it, as opposed to health care cost barriers. Making sure that a kid knows there’s going to be dinner and food on the table because that psychological stress<\/a> isn’t just psychological,” said Pontzer. “It gets into the way your body works.”<\/p>\n More information:<\/strong> \t\t\t\t\t\t\t\t\t\t\t\tProvided by \t\t\t\t\t\t\t\t\t\t\t\t\t<\/a><\/p>\n \n Citation<\/strong>: \n This document is subject to copyright.
