Unlocking Lifelong Bone Health: Saskatchewan Leads Global Study with Advanced 3D Scanner

In a pioneering effort that could reshape our understanding of pediatric bone health, researchers in Saskatchewan are leading a world-first study utilizing a state-of-the-art 3D X-ray scanner. This groundbreaking initiative aims to unravel the intricate relationship between diet, exercise, and bone strength in children, laying crucial groundwork for preventing osteoporosis later in life.

The stakes are high.

Osteoporosis, a debilitating condition characterized by fragile bones, often has its roots in childhood and adolescence when bone mass is rapidly accumulated. Understanding how to optimize bone development during these critical years is paramount. "Up to 90 per cent of our bone mass is established by our early 20s," explains Dr.

Saija Kontulainen, a prominent researcher at the University of Saskatchewan and a driving force behind this study. "If we miss the window to build strong bones in childhood, it's incredibly challenging to catch up later."

At the heart of this innovative research is a high-resolution peripheral quantitative computed tomography (HR-pQCT) scanner, located at the University of Saskatchewan.

Unlike traditional X-rays, this cutting-edge technology provides unprecedentedly detailed 3D images of bone microstructure. It allows researchers to meticulously examine both cortical bone (the dense outer layer) and trabecular bone (the spongy inner network), offering insights into bone density, geometry, and microarchitecture that were previously impossible to obtain in a live setting.

This precision is vital for identifying subtle changes in bone structure that could indicate future risk.

The study, a collaboration between the University of Saskatchewan and the Saskatoon Child and Youth Health Network, will follow approximately 160 children aged 7 to 10 years over a five-year period.

Participants will undergo regular assessments every 18 months, during which their physical activity levels, dietary intake (with a particular focus on dairy consumption), and bone health will be carefully monitored using the advanced scanner. This longitudinal approach is key to observing how lifestyle factors dynamically influence bone development over time.

The research team is spearheaded by Dr.

Kontulainen, alongside Dr. Sara Pearcey and Dr. Adam Baxter-Jones, all renowned experts in bone health and pediatric physiology. Their collective expertise ensures a comprehensive approach to this complex field. The study has garnered significant support, including funding from the Saskatchewan Health Research Foundation and the Dairy Farmers of Canada, underscoring its potential impact on public health recommendations and dietary guidelines.

By shedding light on the critical interplay of nutrition, activity, and bone development during childhood, this Saskatchewan-led study is poised to deliver invaluable knowledge.

The findings could pave the way for more effective public health strategies, personalized interventions, and educational programs designed to empower children to build stronger, healthier bones for a lifetime, ultimately reducing the burden of osteoporosis for future generations.
