A Melbourne-led study has found a link between early-life infections and cardiovascular disease risk in adulthood, offering opportunities for targeted intervention.

The study led by the found that elevated inflammation markers and changes in metabolism 鈥� the way the body鈥檚 cells process food into energy聽鈥� observed in infection-prone infants resembled those in adults at risk of cardiovascular disease.

The findings suggest that the impact of cumulative infections in infancy could predispose adults to a higher risk of heart disease, obesity, stroke and type 2 diabetes, said researcher Dr Toby Mansell from MCRI.

鈥淲e found the risk of adult-onset cardiovascular disease could be accruing from early life,鈥� he said.

鈥淲e know babies are prone to infections. This causes inflammation, a key cardiometabolic risk factor, but the relationship between infection, inflammation and metabolic profiles in early childhood had remained underexplored until this study.鈥�

The study involved 555 infants from the Barwon Infant Study, a collaborative project between Barwon Health, Murdoch Children鈥檚 and Deakin University, with infant infections tracked over 12 months.

The research found high rates of infant infections by 12 months of age were associated with elevated inflammation markers and changes to metabolic profiles, which influence how the body processes fats, proteins and sugars.

Murdoch Children鈥檚 Professor David Burgner said infection had been recognised as a potential contributor to cardiovascular disease, one of the leading causes of death in adults globally.

In Australia, cardiovascular disease accounts for a quarter of all deaths, claiming the life of one person every 10 minutes. More than 4 million Australians have cardiovascular disease and someone is hospitalised with the disease every minute.

Professor Burgner said the research offered opportunities for early prevention measures such as identifying the types of infection and the children at highest risk, and how these risks might be offset by simple interventions.

鈥淭argeted action could include promoting breastfeeding, ensuring timely vaccinations and supporting families so that they can keep children at home if they are unwell with an infection,鈥� he said.
