Cardiovascular disease (CVD) is the primary cause of mortality in women in developed countries. CVD risk rises with age, yet for women there is a rapid increase in CVD risk that occurs after the onset of menopause. This observation suggests the presence of factors in the middle-aged women that accelerate the progression of CVD independent of chrono...

Background: Adiposity in childhood and adolescence (youth) has been shown to associate with adult metabolic health. What is not known, is whether youth body mass index (BMI) associates with metabolically healthy obesity (MHO) in adulthood, and if so, the age when the BMI to MHO association emerges. This study aimed to determine if BMI trajectories...
