    Canadian adults get a failing grade for physical activity

    Only 16 per cent of Canadian adults are meeting the national guidelines of 150 minutes of moderate-to-vigorous physical activity per week, according to a national non-profit. Calling this an “inactivity crisis,” ParticipACTION says inactivity can lead to increased risk of chronic diseases, cognitive decline, falls and social isolation among older adults. It has issued a first-ever report card on physical activity in adults and has given them a grade of D. “Physical activity has been engineered out of our lives,” says Elio Antunes, president and CEO of ParticipACTION, a national organization founded to promote physical fitness and healthy living. “Everything that we have is to make life easier and with less effort. We have a culture of convenience.” A large slice of the Canadian population is aging and becoming more sedentary. They will age better with the benefit of regular physical activity, says Antunes.  ParticipACTION suggests employers have walking meetings rather than book a boardroom. (iStock) Small changes can have big effect ParticipACTION suggests simple ways to start increasing activity such as moving more throughout the day, trying something new, upping the intensity , asking others to join in, breaking up extended periods of sitting and adding strength training two to three times a week. Antunes says three-quarters of adults know they need to be physically active and they want to be. “As individuals, we need to take responsibility. We need to incorporate...even bouts of 10 minutes of physical activity at a time makes a big difference,” he says. “But we also need to ensure that the environment that we’re in supports us wanting to be physically active.” For example, Antunes says municipalities should build communities that encourage walking or other active transportation, health practitioners could prescribe physical activity to patients, employers could create workplaces that encourage movement and hold walking breaks or meetings. Antunes says this is an extremely important issue, especially given that inactivity will increase costs to the health care system by billions of dollars as time goes on. Elio Antunes says physical activity needs to be a vital part of everyday life to all Canadians.EN_Interview_2-20191029-WIE20

    Climate change will challenge new minority government

    In Canada’s federal election, 63 per cent of voters chose parties with strong platforms on mitigating climate change. The Liberal Party will form the government but, since it does not have a majority of seats, it will have to seek the support of other parties in order to govern. Two of these parties strongly favour tougher measures to reduce greenhouse gas emissions.  The New Democratic Party and the Green Party both campaigned hard for major reductions in greenhouse gas emissions. (iStock) Two opposition parties seek stronger climate action “We see that the Liberals, the New Democratic Party...the Green Party...all agree that this country needs to step up the ambition of our climate commitments,” says Catherine Abreu, Executive Director of the Climate Action Network of Canada, a coalition of groups concerned about climate change.  “We need to meet that 2020 deadline set out by the UN to come back to the table with a stronger commitment under the Paris Agreement. We need to legislate..emissions reduction targets...that help us get there, as well as holding ourselves accountable for those commitments and establishing institutions that keep us on track.   But the Conservative Party ran on a promise to kill the carbon tax that the previous Liberal government levied on provinces. The leaders of the oil-rich, western provinces of Alberta and Saskatchewan are opposed to the tax and other environmental measures that would weaken the oil industry.  The challenge of the new minority government will be to reconcile those conflicting visions.  Political parties recognize there will be a need for a transition from oil industry jobs to greener alternatives. (iStock) Parties agree job diversification needed Some of the parties emphasized a need for economic diversification and job creation as the country moves away from fossil fuel industries and toward what they call a climate-safe future.  Abreu likens the situation to the collapse of the cod fishing industry in the 1970s in eastern Canada that forced families to leave and seek work in other parts of the country. “Even though politicians foresaw the collapse of the cod fishery, they didn’t plan for it. And I want us to make sure that we are not in the same position in the next couple of decades, that we see that the oil and gas industry...does need to wind down gradually...over time, and that we need to plan and prepare for it, have conversations with workers and communities about what they need to prepare for it and invest in the industries of the future that are going to protect people and the planet.” The Liberals will form a government with 157 seats, leaving it short of the 13 required for a majority. For support on climate issues, it can seek the help of the NDP which obtained 24 seats, the Bloc Quebecois which garnered 32 seats, and/or the Greens with three. Conservative Party is a strong supporter of the oil industry The Conservative Party which supports the oil industry obtained 32 seats and so, does not have enough to topple the government if it disagrees with climate policy.  However, even though his Liberal Party did not win any seats in Alberta and Saskatchewan, Prime Minister Trudeau has said he wants to serve people there as well and he plans to go ahead with the expansion of the Trans Mountain Pipeline to bring oil product to tidewater. The NDP, the Bloc Quebecois and the Greens are opposed.  The prime minister has made no formal alliance with any party and says he will seek their support on a case-by-case basis. It will be interesting to see how he manages. A minority government in Canada typically falls in about 18 to 24 months. Catherine Abreu says there will be much opposition party support for strong action to mitigate climate change.EN_Interview_2-20191024-WIE20

    Depression link to inflammation explained in book

    A new book suggests that depression should be considered an inflammatory illness. That is to say, depression can provoke high levels of stress hormone which cause certain brain cells to stop working properly and to produce proteins that cause inflammation. Inflammation can cause other problems like heart disease, diabetes and obesity. “When you have multiple or very severe episodes (of depression) there’s actually an inflammatory cascade that is set up in the brain and it can lead to real measurable changes in the brain’s structure and functioning,” says Dr. Diane McIntosh, a psychiatrist  and author of the book This is Depression: A Comprehensive Compassionate Guide for Anyone who Wants to Understand Depression. “We can see in the brains of chronically, severely depressed patients that they have shrinkage of particular brain areas, one called the hippocampus. We can measure that in people who have severe and chronic depression and that’s related to an inflammatory cascade.” Severe and chronic depression can cause changes in the brain. says author. (iStock) Treatment must be tailor-made, says psychiatrist McIntosh says there are no specific anti-inflammatory treatments for depression yet and there is much work being done to be more specific in the targeting of depression. However, many current treatments for depression do have an impact on the inflammatory system and neurotransmitters, and they help nourish the brain. Among the treatments are anti-depressants, electro compulsive therapy, and exercise to can have a beneficial effect. The difficulty is that everyone is different and every treatment needs to be tailor-made for each patient. Things like yoga and mindfulness can also help patients manage their symptoms. McIntosh says there is much trial and error involved in finding the right regimen for each patient. Dr. Diane McIntosh says depression is complex and involves inflammation.EN_Interview_2-20191023-WIE20

    Exercise can help with cancer and help prevent it, says panel

    An international panel of experts in cancer and rehabilitation has devised new guidelines to help people prevent cancer or recover from it and improve their survival. “In terms of cancer treatment, we know that being active, in theory, has been safe. We’ve done a lot of research there and it’s beneficial,” says Kristin Campbell, associate professor of physical therapy at the University of British Columbia and the Canadian representative on the international panel. Exercise said to reduce fatigue, anxiety, depression “The research suggests that 30 minutes of aerobic activity, three days per week and two days a week of strength training can reduce cancer-related fatigue, improve feelings of anxiety and depression, improve your physical function and improve your overall quality of life.” The panel suggests doctors work out an exercise plan with cancer patients as part of their overall recovery regimen. (iStock) Exercise said to help prevent 7 cancers The panel also found that 150 minutes of moderate to vigorous physical activity like brisk walking or running can reduce the risk of getting seven common cancers. They are colon, breast, endometrial, kidney, bladder, esophagus and stomach cancer.  A new program has been devised to help health care providers ensure that people living with and beyond cancer are assessed and referred to appropriate exercise and rehabilitation as part of their overall care.  The Canadian Society for Exercise Physiology was one of the 17 groups on the panel which also included American Cancer Society, German Union for Health Exercise, Exercise and sport Science Australia among others. Prof. Kristin Campbell explains what exercise can help prevent cancer or improve the lives of cancer survivors. (Martin Dee/University of British Columbia)EN_Interview_2-20191018-WIE20

    Bias, discrimination prevent people getting obesity care: study

    Science shows that obesity is a chronic disease like diabetes or cancer, yet people living with it are being told “they did this to themselves, and that they don’t deserve to be supported,” says Dr. Arya Sharma, the scientific director for the non-profit Obesity Canada.  Misconceptions abound, says doctor He says a new survey shows there are many misconceptions among health care professionals, employers and people living with obesity.   The latter “shouldn’t look at this as being their own fault. This is something that happens to people in the same way that diabetes...or high blood pressure happens to people.  And when it happens...you need to get treatment that actually works,” says Sharma. While exercise is good for everyone, it and diet change alone are not enough to treat obesity, says doctor. (iStock) Better and long-term help is needed He adds, too many doctors simply recommend a change of diet and exercise, but that is not enough to treat obesity. People may need medication, cognitive behavioural therapy and, in some cases, bariatric surgery. And they need to understand there is no cure and the disease will require lifelong management. There are strong biological reasons that weight returns after weight loss and it is a long-term battle to fight them. Discrimination said to be 'deeply ingrained' Sharma says that weight bias and discrimination are “deeply ingrained among health care providers and employers and this is preventing people from accessing meaningful obesity care.” For example, employers often provide extended health benefits but don’t cover the cost of medications of psychological services to treat obesity.  In Canada, there are some seven million people living with obesity and the incidence is projected to reach 30 per cent of the population by 2030.  The Canadian Medical Association and the American Medical Association have recognized as a chronic disease, but not everyone has. Sharma says it’s time for people to understand that obesity is a complex problem and they should start removing the obstacles people face in getting the care they need. Dr. Arya Sharma describes obesity as a chronic disease which is misunderstood making it difficult for people to get treatment. (Obesity Canada)EN_Interview_2-20191017-WIE20 Survey involved over 2,500 respondents The Awareness, Care and Treatment in Obesity Management (ACTION) Study collected information from 2,000 individuals living with obesity,  395 doctors and allied health professionals who manage it, and 150 employers. Results were published in the journal Clinical Obesity in October 2019.

    Do we trust science? McGill professor weighs in

    A recent study suggested there was not enough evidence to prove that people should avoid eating red meat and processed meats. This ran contrary to previous studies which have, for years, suggested that  consumption of these meats should be reduced to avoid cardiovascular disease.  The study caused much controversy particularly when it was revealed that one of the 13 scientists involved had five years earlier conducted a study on sugar which received some funding by an industry with a vested interest. The scientist was criticized for not reporting that in the current study on meat. However the journal publishing the study only requires a scientist report any conflict of interest that occurred within the last three years. Study not 'really meaningful,' says professor “It’s irrelevant, irrelevant when it comes to this paper,” says Prof. Joe Schwarcz, director of the McGill University Office for Science and Society. “What we should be looking at is whether the advice that they (the authors of the study) are now giving, that people … do not need to cut back on their meat consumption because there is just too little evidence that they will reap any benefit... that’s what we need to look at...Unfortunately I don’t think it’s very meaningful.” The safety of eating meat depends on many factors such as portion size, how the meat is prepared and one’s own health conditions. (iStock) Many factors to take into account Schwarcz says weak evidence is not the same as no evidence. This study did not look at portions, how the meat is cooked, how often it is consumed and what is being eaten with it. Nor does it take into account who is eating it and what their medical profile may be. Schwarcz is less concerned by who may have funded a study than he is by which studies may have not been published out of concern for the effect on funders. “That’s why, these days, what I push for is some sort of agency that would require that any study that is undertaken be registered with that agency before the study is started, so that you can’t hide the data and you’d be forced to publish even if it’s contrary to what you would like it to be.” The official Canada Food Guide consists of half fruit and vegetables, one-quarter whole grains and one-quarter various sources of protein. (Government of Canada) Canada Food Guide based on best science, says professor Schwarcz’s view is that the Canada Food Guide has the correct recommendations for what people should eat based on the current science. And that suggests that half a dinner plate should hold vegetables and fruit, one-quarter should hold whole grains and the last quarter should hold a protein that could be meat, fish, beans or lentils, or nuts. He is concerned that conflicting studies may shake people’s confidence in science, as may sensational media reports about them. But he urges people to look at studies and to assess their methods and accuracy. And he adds, people can always turn to his office which is neutral and dedicated to making science accessible to the public. Prof. Joe Schwarcz says scientific studies should be registered before they begin. (YouTube)EN_Interview_2-20191015-WIE20

    Extinction rebellion action in Canada: measured success

    On October 7, 2019, Extinction Rebellion activists blocked several bridges in Canada and succeeded in drawing attention to their message that climate change is an emergency already underway. The movement’s name refers to the belief that the world has entered the sixth global mass extinction event. It’s symbol is an hourglass that represents the view that time is running out. The group’s first protest in 2018 rallied 1,500 activists in London, England, and has since spread to more than 60 countries.  When compared with the large student marches led by Swedish teenager Greta Thunberg, actions by Extinction Rebellion tactics are more intense.  Three protesters scaled a Montreal bridge on Oct. 8, 2019, forcing police to shut it down during rush hour. (Simon Marc Charron Radio-Canada) Dramatic acts sometimes break the law “Extinction Rebellion engages in non-violent, direct action, where they do dramatic acts. Sometimes they even break the law,” says Patricia Wood, a geography professor at York University and author of Citizenship, Activism and the City.  “They are trying to really draw attention and interrupt our daily lives.”  They occupy urban space in a way that disrupts commutes, they have glued themselves to government buildings and they sometimes wear colourful costumes and use creative signage.”  Some activists, like the one in the background on an Edmonton street, wear colourful costumes to draw attention to their demands. (Amber Bracken/The Canadian Press) Negative reaction can help, says author There has been some negative reaction to the tactics, notably from commuters who argue that sitting in their cars on blocked bridges emits more greenhouse gases contributing to climate change. But Wood says that can further the activists’ goals. “It certainly is annoying and that’s kind of the point, right, is to interrupt and annoy people as a way of really getting their attention around the urgency of this question because, while a lot of people may acknowledge the reality of climate change and the need to do something, there’s...an accurate sense that we’re not doing enough and we’re not doing it quickly enough.” More action coming next week Wood thinks the action has succeeded in drawing more attention to the urgency of climate change in that there has been extensive media coverage and efforts by journalists to delve more deeply into the subject, and politicians have been talking more about it, particularly in Canada’s current election campaign.  There will be another week of intense actions by Extinction Rebellion and Wood says she will be interested to see if they grow in size and drama, and whether governments respond. “If governments do not respond to them, I think it’s likely that we could expect to see an escalation in tactics because certainly, the science is on their side. They’re right and the urgency isn’t going away.” Prof. Patricia Wood discusses the tactics of climate activists with Extinction Rebellion. EN_Interview_2-20191011-WIE20

    Eye scan may soon permit early detection of Alzheimer’s

    Canadian researchers are testing a new technology that could be widely used for early detection of Alzheimer’s disease which causes problems with memory, thinking and behaviour. Current tests involve PET scans or spinal taps. But a new technology has been developed involving a simple eye exam that could be done during routine eye checkups.  “The hyper spectral camera...is able to measure how light is reflected from the back of the eye--the retina,” says Dr. Sharon Cohen, medical director of the Toronto Memory Program. “The pattern of reflection translates into whether we have a signature of Alzheimer’s disease or not. It’s an ingenious biotechnology…(that would make) diagnosis pain free, inexpensive, accessible and scalable to the global population.” Incidence of Alzheimer's increasing worldwide There are over half a million Canadians living with Alzheimer’s now and that increases by 25,000 every year, notes Cohen. Globally, 50 million people have this form of dementia and there are expected to be 150 million by the year 2050. The scan of the eye can detect signs of amyloid, a toxic protein characteristic of Alzheimer’s disease. (Cole Burston/RetiSpec) Early diagnosis helps research, helps people While there are no cures for Alzheimer’s, Cohen says it is still vital to have an easy way to diagnose it. “Most cases are either undiagnosed or diagnosed late at the point of crises when families are struggling to cope. So, putting a label on what’s wrong with somebody is not trivial. It allows people to get care, to get information and to join clinical trials that will move forward the treatments of the future. “It also helps research. If we properly identify and identify early who has or is developing the disease then we’re much more likely to hasten the treatment breakthroughs that we so badly need.” Researchers at the Toronto Memory Program are doing validation studies now comparing the results they get with a retinal scan of patients who have had a PET scan or examination of spinal fluid. If the results are the same, they hope to commercialize the eye scanning technique and have it available within one year. Dr. Sharon Cohen explains how the RetiSpec technology works and why it is so important. (Stephanie Cohen)EN_Interview_2-20191008-WIE20
