Detecting Cardiometabolic Risk Signatures in Childhood

The journey toward chronic illness often begins much earlier than standard medical checkups capture. Investigators utilized a group of 273 children participating in the Border Health Research Cohort at the UTHealth Houston School of Public Health in Brownsville. By examining 5,000 proteins in the blood, the team mapped six distinct protein signatures that heavily influence a person’s likelihood of developing cardiovascular-kidney-metabolic disease later in life.

Crucially, these exact same protein markers appeared in 685 adults from the same Brownsville community who already faced high risks of irreversible disease, according to the research team. Senior authors Joseph McCormick, MD, professor of epidemiology and James H. Steele, DVM, Professor at the School of Public Health, along with Susan Fisher-Hoch, MD, professor of epidemiology, established the Cameron County segment of the cohort back in 2014.

“The cohort provides key silent markers of chronic disease traits that are manifest in adults, including some parents of the children, with clinical disease. These children have generously participated in the study at our Clinical Research Unit in Brownsville,” McCormick stated.

Fisher-Hoch praised the local workforce that made the detailed biological mapping possible. “Nearly 20 staff, recruited from the same community and provided appropriate skills, did the hard work of conducting the detailed study of the children in our clinical research unit and laboratory. The community-based team is immensely proud of the contribution of their efforts to human health,” Fisher-Hoch noted.

Validating Proteomic Signatures Across International Populations

To ensure the discovered protein markers held universal predictive power, the research team checked their models against outside populations. Led by first author Heather Highland, PhD, assistant professor of epidemiology at the School of Public Health, the group evaluated disease outcomes among more than 28,000 adults enrolled in the UK Biobank, a large-scale prospective study tracking over 500,000 residents in the UK.

Individuals within the UK Biobank who shared these specific protein patterns faced a markedly higher threat of suffering a heart attack or other severe health complications linked to cardiovascular-kidney-metabolic disease. These circulating proteins act as early warning lights across the body’s systems.

“Understanding the development of cardiovascular-kidney-metabolic disease across the lifecourse is critical,” Highland explained. “Proteins circulating in the blood can serve as markers of nascent pathologies across the body. These early markers can help identify people at greater risk for increased monitoring and potentially early intervention.”

Reversing Disease Trajectories With GLP-1 Drugs

While discovering early risk markers changes how physicians might screen patients, the most striking revelation involves how easily those markers can shift. When the team cross-referenced their protein signatures with outcomes from GLP-1 drug trials, they discovered that the vast majority of high-risk proteins found in adults facing irreversible disease actually changed course when patients took GLP-1 drugs.

This discovery reframes chronic cardiometabolic decline from an unchangeable genetic fate into a manageable condition. Kari North, PhD, director of the Border Health Research Center and professor at the School of Public Health, served as the corresponding author for the study published under doi: 10.1038/s42255-026-01589-7.

“This association is really one of the most exciting messages, because those proteins that predict the risk of cardiometabolic diseases all moved in a healthy direction after these adults took GLP-1. This makes this a modifiable risk state rather than a fixed marker of fate,”

North added that the window of opportunity opens long before adulthood sets in. “Childhood is the time that we really need to start intervening because it’s reversible,” North emphasized.

Shifting Toward Pediatric Precision Medicine and Screening

Many pediatric participants in the Brownsville cohort already displayed physical traits tied to cardiovascular-kidney-metabolic disease, such as elevated body weight, altered liver function tests, abnormal cholesterol numbers, and insulin resistance. Yet, the advanced blood assays used by the UTHealth Houston researchers go far beyond standard pediatric checkups.

The findings advocate for a fundamental upgrade in pediatric screening protocols and a pivot toward precision medicine. Catching hidden protein dysregulations early allows healthcare systems to alter a child’s health trajectory before irreversible damage occurs.

“The dysregulation of the proteins that influence risk of heart attack later in life, if we can reverse them in childhood, then we can really make a huge dent in the cardiovascular disease burden that we see in adult populations around the world today,”

“We need to do better screening in children, and if we see children who are at an elevated risk, the time to act is now,” North concluded.
