Sedentary Behavior Does Not Predict Low Bone Density (BMD) Nor Fracture - CaMos Study 2024

Population-based Canadian Multicentre Osteoporosis Study.

Published in the Journal of Bone and Mineral Research, 24 January 2024. 

 

Are you concerned about the impact of sitting on your bone health?

A recent study funded by Canadian Institutes of Health Research (CIHR) finds that sitting does not impact bone health. The Canadian Multicentre Osteoporosis Study (CaMos), a random trans-Canadian population-based investigation of women and men, has revealed some fascinating findings about sedentary behavior and its effects on bone mineral density (BMD) and fracture risk.

Understanding Sedentary Behavior

First, let’s clarify what we mean by sedentary behavior. It refers to the amount of time spent sitting or engaging in activities with very low energy expenditure. Think of the hours you spend sitting at your desk, watching TV, or using your phone – that’s sedentary behavior.

The Study

Researchers from CaMos examined data from over 8,000 adults aged 25 and older to understand the relationship between sedentary behavior, BMD, and fracture risk. They measured participants’ sitting time and BMD at baseline and then followed up after 10 years to see if there were any changes.

Surprising Results

Despite common beliefs that sitting for long periods can harm bone health, the study found no significant association between sedentary behavior and BMD loss or fracture risk. Even participants who reported spending the most  time sitting did not show an increased risk of fractures over the 10-year period.

What Does This Mean for You?

If you’re worried about the amount of time you spend sitting each day, this study offers some reassurance. Although it is still essential to stay active for overall health and well-being, you can take comfort in knowing that sitting alone may not have a significant impact on your bone health.

Takeaway

It is essential to remember that bone health is influenced by many things, including diet, exercise, and genetics. While reducing sedentary behavior is undoubtedly beneficial for overall health, this study suggests that it may not be as crucial for bone health as previously thought.

As research continues to uncover more about the relationship between lifestyle factors and bone health, it is essential to stay informed and make choices that support your overall well-being. Remember to incorporate regular physical activity (even something as simple as walking for half an hour a day) into your routine, eat a balanced diet rich in vegetables and bone-healthy nutrients, and consult with your healthcare provider if you have any concerns about your bone health.
