who experience parental divorce during childhood have higher levels of an
inflammatory marker in the blood which is known to predict future health,
according to new research from UCL.
study, published in Psychoneuroendocrinology,
found that children who experienced the breakdown in their parent’s
relationship before the age of 16, regardless of whether their parents were
married or not, had 16% higher levels of C-reactive protein at age 44.
protein is a marker of inflammation measured in blood samples. Long-term raised
C-reactive protein is a known risk factor for diseases such as coronary heart
disease and type II diabetes.
study is based on data from 7,462 people in the 1958 National Child Development
Study, an on-going longitudinal study which has followed a large group of
people since their birth in 1958.
authors also looked at why this relationship might exist. They found that the
relationship between parental divorce and later inflammation was mainly explained
by adolescent material disadvantage and educational attainment, although the
specific mechanisms remain unclear. In particular, those who experienced
parental separation before the age of 16 were more likely to be materially
disadvantaged in adolescence and had lower educational qualifications by
adulthood, compared to children who grew up with both parents.
It is not parental divorce or separation per se which increases the risk of later inflammation... it is other social disadvantages, such as how well the child does in education, which are triggered by having experienced parental divorce which are important.
Dr Rebecca Lacey, UCL Epidemiology & Public Health
Lacey, Research Associate in the UCL Department of Epidemiology and Public
Health and lead author of the study, said: “Our study suggests that it is not
parental divorce or separation per se
which increases the risk of later inflammation but that it is other social disadvantages,
such as how well the child does in education, which are triggered by having
experienced parental divorce which are important."
study underlines the importance of supporting separating families in order to
help reduce the risk of later disease. The study concludes: “pathways through
education appear to be particularly important and supporting children through
education may be beneficial."

Council and the National Heart, Lung and Blood Institute.
