5 min read

A brand new examine from the University of Bristol has linked bone strength to the timing of puberty.

Published in the present day (Friday 9 August) in JAMA Network Open researchers checked out six repeated bone scans from 6389 children in Bristol’s Children of the 90s examine between the ages of ten and 25 to assess if the timing of puberty had any affect on bone density all through adolescence and into early maturity.

They discovered that though teenagers who had their pubertal development spurt later than their friends did catch-up to some extent, they continued to have decrease bone density than common for a number of years into maturity.

Peak bone mass on the finish of the teenage development spurts is taken into account to be a sign of later threat of fracture and osteoporosis. Thanks to repeated measures masking 15 years within the giant Children of the 90s examine teachers had been in a position to study how bone density adjustments over time to assess the extent to which later maturating people could ‘catch-up’ with their friends.

Lead creator and Senior Research Associate in Epidemiology Dr Ahmed Elhakeem mentioned:

Our analysis provides to the proof that children who mature later could also be at elevated threat of fractures as they develop. They may have elevated threat of the delicate bone situation osteoporosis in later life.”

Thanks to the Children of the 90s examine we had been in a position to look, for the primary time, at children in nice element as they develop into younger adults and observe their bone density. I’d like to see extra recommendation out there for individuals who attain puberty in a while measures they’ll take to strengthen their bones.

The subsequent steps ought to contain extra detailed assessments of the long-term results of puberty on development and bone improvement.”

Alison Doyle, Head of Operations and Clinical Practice on the Royal Osteoporosis Society, mentioned:

This is necessary analysis that provides to a present hole within the proof of understanding how bone density adjustments from puberty into early maturity.

Investment on this space of analysis is important in furthering our understanding of the causes of osteoporosis and serving to folks to keep good bone well being all through life.

Understanding adjustments in bone density throughout puberty, and the interventions that individuals can take for his or her bone well being now to stop osteoporosis and fractures sooner or later, is a vital step ahead to find a treatment for this illness.

The charity’s Osteoporosis and Bone Research Academy, which launched earlier this yr, is working to construct on these findings and create a future with out osteoporosis.”

The examine didn’t make conclusions on any affect of the ultimate grownup top on the findings. As the examine members are nonetheless solely of their twenties comply with up with them as they age can be necessary to attain conclusions about fractures in later life.
