About the research project
Over 1 million Australians suffer from osteoporosis, and this is likely to increase due to our ageing population and sedentary behaviour. The importance of bone acquisition in childhood and adolescence to optimize peak bone mass has been recognized as one of the key strategies in the prevention of osteoporotic fractures. A better understanding of the determinants of bone acquisition from infancy through childhood is therefore of fundamental importance to the prevention of osteoporosis in adulthood.
The gut microbiome plays an important role in shaping complex traits and diseases. Evidence is emerging that the gut microbiota affects bone homeostasis. The relationship is complex and involves several mechanisms including: (1) host immune system, (2) modulation of growth factor and hormone production, and (3) the production of specific metabolites, such as short chain fatty acids. To establish whether a different gut microbiota composition is related to subsequent bone health in childhood, longitudinal cohort studies in the general population are essential. This project will directly address this need by investigating the role of the gut microbiota on bone health during childhood.
The project aims to examine the association between:
- Gut colonization patterns early in life and subsequent bone health at age 6–11 years.
- Gut microbiota-derived metabolites, such as short-chain fatty acids, early in life and subsequent bone health at age 6–11 years.
The research will be conducted in two population-based observational birth-cohorts: the Copenhagen Prospective Studies on Asthma in Childhood (COPSAC) from Denmark and the Barwon Infant Study (BIS) from Australia. In a total of 1,500 children, faecal samples were collected during infancy and childhood to characterize the microbiome and its derived metabolites in faeces, urine and blood and bone health will be determined at age 6-11 years.
