A new study reveals that biological markers linked to heart and metabolic diseases can be detected in children from the age of eight, potentially allowing earlier intervention to prevent future health issues.
A new study suggests the biological roots of heart and metabolic disease may be visible far earlier in life than doctors once thought, with risk patterns detected in children as young as eight. Researchers from Vanderbilt Health, UTHealth Houston and the University of North Carolina at Chapel Hill examined blood samples from 273 children and adolescents and found that more than a third already showed physical and metabolic traits linked to cardiovascular-kidney-metabolic disease, including obesity, raised blood pressure, insulin resistance and unhealthy blood fat levels.
Published in Nature Metabolism, the study used machine learning to search for protein patterns in the blood that travelled with these traits. The researchers say they identified a distinct protein signature associated with cardiometabolic risk, raising the possibility that changes linked to future disease may begin long before symptoms appear. In the same analysis, the pattern was also seen in 685 adults from the same community and in more than 28,000 adults in the UK Biobank, which strengthens the case that the signal is not confined to childhood.
The findings add to a growing body of work suggesting that early biology can foreshadow later illness. Previous research in children has pointed to blood-based gene changes in obesity and other early metabolic shifts, while more recent studies have explored similar links through the gut microbiome and metabolism. Taken together, those studies suggest that children’s blood and metabolic profiles may offer clues to later heart, kidney and metabolic disease well before a diagnosis is made.
The researchers also noted that some of the proteins in the signature have been shown in adult studies to fall after treatment with semaglutide, a GLP-1 medicine used for diabetes and weight management. They stressed, however, that their work does not mean children with these markers should be given weight-loss drugs. The study was relatively small and focused on one community, so larger research will be needed before the findings can be used in routine care. Even so, the authors say such protein signatures could eventually help identify higher-risk children early enough for action through diet, activity and, where necessary, treatment.
