While commonly chronic conditions such as osteoporosis are associated with geriatric populations, there is a growing body of research that focus on these conditions in the context of a “paediatric disease with geriatric consequences”. Maximising bone mass accrual in childhood and early a key strategy in reducing the risk of osteoporosis in later life. This presentation will focus on early life predictors of bone health using research examining associations between maternal dysglycaemia during pregnancy and offspring bone health as a focal example. Adults and children with diabetes mellitus have poorer bone health and greater likelihood of fracture compared to healthy populations. Thus, it is plausible that the glycaemic environment in utero may impact offspring bone development. Studies examining bone outcomes in the offspring of mothers with gestational diabetes are conflicting and limited, and no study has examined these outcomes beyond infancy. Using data from the Vitamin D in Pregnancy study we examined associations with maternal gestational dysglycaemia and offspring bone health in childhood in children aged 8-11 years of age. We found that children of mothers who were dysglycaemic during pregnancy had a 2-fold increased risk of childhood fracture. There was no overall association was detected with maternal glycaemic status during pregnancy and child BMD. There was, however, evidence of a sexually dimorphic association, whereby mothers who were dysglycaemic during pregnancy had boys with higher bone density. Together, in boys, these associations mirror that of individuals of Type 2 diabetes, whereby despite an increase in bone density there is an incongruent risk of fracture.
