Maltreated girls show higher inflammation levels at an early age than boys who are maltreated or children who have not experienced abuse, finds a new study.

Inflammation plays an important role in several chronic diseases of aging, such as diabetes, heart disease, stroke, obesity as well as mental health outcomes, and the findings imply that maltreatment's link with inflammation does not rest dormant before emerging in adulthood. Instead, the study reveals that traumatic encounters have a much more immediate impact.
The study examined 155 kids aged 8-12 from low-income backgrounds who attended a weeklong day camp. The sample was racially diverse and included both maltreated and non-maltreated kids. Information on children's exposure to abuse was captured by utilizing the Department of Human Services records about maltreatment experiences in families.
The team surveyed five biomarkers of low-grade inflammation using non-fasting blood samples from the kids.
Results revealed that girls who had been abused over multiple periods or had multiple kinds of exposures had the highest levels of inflammation. For boys, exposure to maltreatment was not reflected in higher levels of inflammation, but the study author cautioned against drawing conclusions without additional investigation targeted to boys.
