Your Bone Health During COVID-19

Take action to make sure you are staying fracture-free and are taking care of your bone health. This pandemic has put enormous pressure on our healthcare systems stretching our resources to the limit and the general recommendation is for people to avoid hospitals and doctor’s offices unless absolutely necessary.

Remember that older adults and people who have certain chronic medical conditions such as diabetes or lung, heart or kidney disease are at higher risk of the more serious complications of COVID-19 illness. We urge you to stay safe by taking the necessary precautions as recommended by government health agencies.



  • Fall Prevention: ensure that your home environment is free of clutter and any obstacles. Take care when walking outdoors.
  • Do not stop any osteoporosis treatment you have been prescribed. Talk to your doctor if you have any concerns.
  • Physical/Social Distancing does not mean self-isolating! Make sure to call and speak to friends or family at least once a day. Video chats are also a great way to stay connected.
  • The Government of Canada has advised you to stay home. Contact your doctor and/or pharmacy if you need a prescription filled or a consultation.
  • Ask for help! There are many ways to get the support you need for getting prescriptions filled and groceries delivered. Most grocers have a delivery service or an online order system where you can go pick up your order. If you do not have the ability to order online, many volunteer groups have popped up. Call your local elected representative and ask for help in locating such services. Also try contacting a neighbour to see if they can drop off supplies at your door or provide information on a service.

Be prepared to manage your bone health and osteoporosis and reduce your risk of breaking a bone during COVID-19.

  • Nutrition: Many pantry staple foods like beans and canned fish contain calcium and protein. Read product labels and also view the list of foods with calcium here. Click here

  • Stay active! Safely exercise daily by adapting exercises you can do at home. Click here


It’s important to follow recommendations from the Public Health Agency of Canada (PHAC) to stay safe and well informed.


Together, we can slow the spread of COVID-19 by making a conscious effort to keep a physical distance between each other. Social distancing is proven to be one of the most effective ways to reduce the spread of illness during an outbreak.

This means making changes in your everyday routines to minimize close contact with others, including:

  • avoiding crowded places and non-essential gatherings
  • avoiding common greetings, such as handshakes
  • limiting contact with people at higher risk like older adults and those in poor health
  • keeping a distance of at least 2 arms-length (approximately 2 metres) from others


There is an increased risk of more severe outcomes for Canadians:

  • aged 65 and over
  • with compromised immune systems
  • with underlying medical conditions

Tai Chi: Fall Prevention and Bone Health

Shayla Mueller and Veronique Murphy

What is Tai Chi?

Tai Chi is a type of exercise that originally began as a martial art in China hundreds of years ago. It is sometimes described as “meditation in motion” as it engages both the mind and the body. Practising Tai Chi involves using slow, controlled body movements while focusing on breathing. These slow movements increase self-awareness, allowing you to be in complete control of your body. Each movement is held in a specific position for a brief moment before changing to a new position. The transitions involve different movements such as shifting weight from one leg to another, rotating the neck, torso, arms and legs, and stepping in different directions.

Tai Chi focuses on coordination and flexibility, helping to improve your ability to move and complete life’s daily activities. There are many different types of Tai Chi, each with a different pace and style of movement.

Why Should I Consider Tai Chi?

Tai Chi has many positive health benefits including improvements in muscle strength, flexibility and balance. It is a full body exercise that is considered to be equivalent to low or moderate intensity aerobic exercise. This means that you may be able to talk while doing it but not sing a song.

Tai Chi is a popular form of exercise, particularly among older people. It has many advantages, including being an easily accessible, affordable activity available in many communities. No special clothing or equipment is required. It is often practised in groups, providing an opportunity to socialize and meet new people.

Most importantly, research has found Tai Chi to be a safe form of exercise for people with low bone density.

Tai Chi and Fall Prevention

Reducing fall risk is an important way to reduce your risk of fractures. A recent review of studies found Tai Chi to be effective for fall prevention short-term in older adults. In fact, it can reduce the rate of falls by almost 50% during the first year that people are practising Tai Chi. Research has also shown that Tai Chi may improve balance, which is an important part of reducing the risk of falling. People who practise Tai Chi regularly do better on balance tests and their bodies sway less when they are standing. The slow, shifting movements of Tai Chi activate the leg muscles, improving a person’s strength and ability to respond if they become off balance. Many of these studies show benefits after 12 weeks of training. Tai Chi can also help people improve their mobility. Many of the Tai Chi movements copy the movements used in walking, such as shifting weight from one leg to the other and stepping in different directions. Performing these movements slowly and repeatedly allows the brain to adapt and create new connections that can lead to improved walking. This allows people to build confidence in their walking and be less afraid of falling.     

Effect of Tai Chi on Bone Density

The effects of Tai Chi on bone density have also been studied. A recent review found that regular participation in Tai Chi (45-90 minute sessions between 2 and 7 times a week) for at least 24 weeks may be an effective way to slow the reduction in bone density that is seen in perimenopausal and postmenopausal women, as well as in individuals with osteoporosis. However, more research is required to confirm the results and to determine the amount of exercise and frequency of training necessary to provide benefit.

If you are practising Tai Chi or thinking about taking it up, we know that it:

  • Is safe for people with low bone density,

  • Reduces the rate of falls,

  • Is a whole body and mind exercise that challenges balance,

  • Focuses on coordination and flexibility, helping you perform activities of daily living,

  • Is a group activity, and

  • Is easily available and affordable.

How Does Diabetes Affect Fracture Risk?

Zoe Bond, Dana Li and Rebecca Wills

Diabetes and Fracture Risk

Diabetes mellitus, commonly known as diabetes, is a condition that affects the hormone insulin, resulting in high blood sugar levels. Insulin is needed to absorb glucose (sugar) from the blood to provide energy for cells. In diabetes, there is insufficient insulin to bring glucose out of the blood and into body tissue, and as a result, blood sugar levels are high. People who have Type I Diabetes (T1DM) are not able to make insulin and need insulin injections. Although people with Type II Diabetes (T2DM) are able to make insulin (the levels are actually high), they cannot use the insulin properly and as a result they require medication (either pills or insulin) to lower blood sugar levels.

Diabetes has many effects throughout the body. Abnormal insulin and blood glucose levels can affect the kidneys, nerves, heart, blood vessels and eyes. Diabetes can also have a negative effect on bone, and this means that people with diabetes are at a higher risk of fractures. People with T1DM have low bone density, and almost 20% of people with T1DM who are under the age of 60 have bone density that is low enough to be considered osteoporotic. However, people with T2DM appear to be protected against bone loss, and bone density can be normal. Studies have shown that individuals with T2DM actually have higher bone density than people who do not have diabetes. This suggests that the bone quality, another determinant of bone strength, may be poor and may explain increased fracture risk in T2DM.

In order to calculate a person’s fracture risk, doctors can use an assessment tool that considers risk factors such as: age, height, weight, previous fractures, family history of osteoporosis, personal habits like smoking and alcohol consumption, particular medications, certain medical conditions such as rheumatoid arthritis and results from a bone density scan. However, it is now recognized that current risk assessment tools underestimate fracture risk in people with diabetes and current research is looking at tools that may improve our ability to assess their risk.

Changes in bone density and bone quality are not the only ways that diabetes can increase a person’s risk for fracture. Diabetes can also increase the risk of falls. Falls are more common in people with diabetes because diabetes can lead to complications such as reduced sensation in the feet, reduced vision and increased light-headedness. In addition, if someone with diabetes has low blood sugar (hypoglycemia), they are at increased risk of falling. The combination of more fragile bones and a higher risk of falls increases the risk of fracturing a bone. The bones commonly fractured by people with diabetes include the upper arm, wrist, hip and spine.

Fracture risk is significantly increased in T1DM. Men with T1DM are twice as likely to fracture a bone as compared to men without diabetes. The risk is four times higher in women with T1DM compared to women without diabetes. People with T1DM are also more likely to fracture earlier in life compared to the average person without diabetes. In addition, the longer a person has lived with T1DM, the higher their risk of fracture.

People with T2DM also have a higher risk of fracture. Factors that increase this risk include having T2DM for longer, poor blood glucose control and the presence of diabetic complications such as eye or kidney involvement. Those with T2DM have as much as a 70% higher chance of suffering a non-spine fracture compared to those without diabetes. In addition, many patients with T2DM have low levels of vitamin D, which is needed to keep bones strong.


If you have diabetes, either Type 1 or Type 2, you are at a higher risk of suffering a fracture, both because of the effects of diabetes on bone and because of the increased risk of falling.

Diabetes Medications and Fracture Risk

There are many medications available to help control blood glucose levels. Research has shown that some may increase bone strength and reduce the risk of fracture, while others may have a negative effect on bone and increase the risk of fracture. Metformin is thought to be good for bones. Some animal experiments suggest that Metformin has a positive effect on bone health by increasing bone building cells (osteoblasts) and decreasing bone absorbing cells (osteoclasts). Thiazolidinediones (TZDs) have been shown to do the opposite, decreasing the development of cells that build new bone while increasing the number of cells that break down bone. This means a person with T2DM taking TDZs is at a greater risk of fracturing bones because the amount of bone loss is greater than the amount of new bone made. A number of studies have shown that hip fractures are increased in people taking TZDs, and that the risk increases with longer duration of use. Another diabetes medication, canagliflozin (Invokana ®), has also been found to be associated with an increased risk of fracture, although at this time no mechanism has been identified. Many of the medications used to treat diabetes can increase the risk of low blood sugars, which is a risk factor for falls.

What Does This Mean For You?

If you have diabetes, either T1DM or T2DM, you are at a higher risk of suffering a fracture, both because of the effects of diabetes on bone and because of the increased risk of falling. There are many different medications currently used to treat diabetes, and some of these can affect bone health. It is important to speak to your doctor or healthcare practitioner to have a full assessment of your diabetes and bone health. This should include a fracture risk assessment, reviewing diabetes medications to make sure they are right for you, and assessing for risk of falls. Taking part in a regular exercise program that includes balance and strengthening exercises is an excellent way to help maintain your bone density, reduce your risk of falls and fractures, and benefit your overall health.

Zoe Bond, Dana Li and Rebecca Wills are 4th year Kinesiology students at the University of Waterloo (at time of writing). The authors were introduced to fracture risk in those with diabetes mellitus during a course on bone health. They found the topic intriguing and therefore chose to engage in further research. They hope that this article will be informative for those living with both osteoporosis and diabetes.
