Our Cardiometabolic Special Interest Group is able to investigate areas of human heart and vessels health and disorders, liver and gastrointestinal function. The group has a range of measures on our participants relating to blood pressure, heart rates, vascular function, liver and gastrointestinal function, gut microbiome, and blood and urine markers of heart, vessel, liver and gastrointestinal function across different ages and generations within the Raine Study.

Key Findings over the last 30 years include:
Using information collected from the Raine Study participants, researchers found that mothers’ exposure to stress during pregnancy predicts higher body weight, but lower blood pressure in offspring at early adulthood. Additionally, infants who breastfeed for less than six months before starting formula and who were obese as teenagers or had mothers who were obese during pregnancy were more likely to have non-alcoholic fatty liver disease in adolescence, while breastfeeding for at least six months were associated with reduced risk for this disease in adolescence. Researchers also showed that measures of the body’s stress response system and vitamin D levels are associated with a range of factors related to risk of developing heart and vessels disease in adolescents.
Maternal exposure to life stresses during pregnancy predicts increased weight but lower blood pressure in offspring at 20 years of age.

Infants who consumed breast milk for less than six months before starting infant formula milk and infants who were obese as teenagers or had mothers who were obese at the start of pregnancy, were much more likely to have non-alcoholic fatty liver disease in adolescence.

Risk for non-alcoholic fatty liver disease during adolescence is identifiable from trajectories of weight and body mass index from age three years onwards.

Positive association between handgrip strength and back muscle endurance with systolic blood pressure throughout childhood and adolescence contrasts with beneficial effects on other related traditional cardiometabolic risk factors.

In adolescents, measures of the body’s stress response system is associated with a range of factors related to risk of developing heart and vessels disease.
