BJSM Podcast

Did you know that worldwide, more than one in four adults (28% or 1.4 billion) are physically inactive? In some countries, it’s as high as one in three! How many more times do we need to be reminded that physical inactivity is one of the leading risk factors for global mortality before we finally decide to get off the couch? On this week’s episode, Prof Fiona Bull MBE (T: @fiona_bull) joins BJSM’s Daniel Friedman (T: @ddfriedman) to discuss the latest physical activity trend data and explain how clinicians can play their part to increase levels of physical activity for a more active world. Prof Bull is the Programme Manager in the Department of Prevention of Noncommunicable Diseases (NCD) at the World Health Organization based in Geneva, Switzerland. She leads the WHO’s global work on physical inactivity, healthy eating and the prevention of obesity, and provides leadership for global monitoring and surveillance of NCDs and their risk factors. Bull joined WHO in 2017 after 25 years in applied research in Australia, the UK and the USA. Her recent positions include Professor of Public Health and Director of the Centre for Built Environment and Health at the University of Western Australia and Professor of Sports Science and Director of National Centre of Physical Activity at Loughborough University in the UK. Bull has co-authored over 180 scientific publications and reports. Her interest is in bridging the knowledge-policy-practice gap, and she has been actively involved in civil society. She is immediate past President of the International Society of Physical Activity. In 2014, Bull was awarded a Member of the British Empire (MBE) for her services to public health. In this 15 minute conversation, Prof Bull addresses: · Physical inactivity trends over the past 16 years · The causes of physical inactivity · What the WHO is doing to support countries increase physical activity · What clinicians can do to play their part Further reading: Guthold R, Stevens GA, Riley LM, Bull FC.

Traditionally, sports medicine may have focussed on joints and tendons and muscles, but, as with medicine more widely, nutrition is now being properly recognised as an essential aspect of health. Food is a very strong lever to improve human health and environmental sustainability on earth. However, food is currently threatening both people and planet. The food we eat, the ways we produce it, and the amounts wasted or lost affect us all – athletes, patients and clinicians. On this BJSM podcast Prof Jess Fanzo (T: @jessfanzo) from Johns Hopkins (full bio below) joins BJSM’s Daniel Friedman (T: @ddfriedman) to discuss the recently published report Food in the Anthropocene: the EAT–Lancet Commission on healthy diets from sustainable food systems that is making headlines around the world. The report is also creating much controversy. Not everyone will agree with the commission, just as not everyone agrees with all nutrition advice. At BJSM, our job is to share major views from the scientific world with our community and here you can listen to a major player in this report. In this 15-minute conversation, Prof Fanzo shares the report’s key takeaways (!) and how sport and exercise medicine clinicians can contribute to “the great food transformation". Prof Jess Fanzo PhD is the Bloomberg Distinguished Associate Professor of Ethics and Global Food & Agriculture at the Johns Hopkins Berman Institute of Bioethics, the School of Advanced International Studies, and the Bloomberg School of Public Health, Department of International Health. She also serves as the Director of the Global Food Ethics and Policy Program. Prof Fanzo received her PhD in Nutrition at the University of Arizona, and was the Stephen I. Morse Postdoctoral Fellow in Immunology in the Department of Molecular Medicine at Columbia University. https://eatforum.org/contributor/dr-jessica-fanzo/ Have something to say about the commission or the podcast?

Did you know that fewer than 15% of women will actually achieve the minimum recommendation of 150 min per week of moderate-intensity physical activity throughout their pregnancy? Meeting the recommendation can reduce the risk of pregnancy-related illness such as depression by at least 25%, and the risk of developing gestational diabetes, hypertension and preeclampsia by 40%! So why are some clinicians still scared to prescribe physical activity to soon-to-be-mums? On this week’s episode, Dr. Margie Davenport PhD joins BJSM’s Daniel Friedman (T: @ddfriedman) to address common misconceptions regarding physical activity during pregnancy and explain the new 2019 Canadian guideline for physical activity throughout pregnancy (https://bjsm.bmj.com/content/52/21/1339) that was recently published in the BJSM. Dr. Davenport is an Assistant Professor in the Faculty of Kinesiology, Sport, and Recreation at the University of Alberta. She received her PhD in Integrative Exercise Physiology from the University of Western Ontario and conducted a two year Postdoctoral Fellowship at the University of Calgary. She is an emerging expert in metabolic and cardiovascular adaptations associated with normal and complicated pregnancies. Her primary interest is in the benefits of exercise prior to, during and following pregnancy for both mother and child. In this 20 minute conversation, Dr. Davenport discusses: · Who should be physically active throughout pregnancy + contraindications · How much physical activity is recommended throughout pregnancy · Examples of physical activity · Common misconceptions and safety precautions Resources: www.exerciseandpregnancy.ca Program for Pregnancy and Postpartum Health videos: https://www.youtube.com/channel/UCtvzYizIALcs5-RzfHrf5UA 2019 Canadian Guideline: http://csepguidelines.ca/wp-content/uploads/2018/10/4208_CSEP_Pregnancy_Guidelines_En_P2A.pdf. https://bjsm.bmj.com/content/52/21/1339

Did you know that one in four people have hypertension? And with recent changes to diagnostic criteria in major clinical practice guidelines, the prevalence is only going to increase. With concerns about the cost, effectiveness, and potential for side effects of antihypertensive drugs, isn’t it time we looked beyond the pharmacy shelves to lower blood pressure? On this episode, Dr. Huseyin Naci PhD (T: @huseyinnaci2) joins BJSM’s Daniel Friedman (T:@ddfriedman) to discuss his recently published BJSM meta-analysis that compares the effectiveness of exercise and antihypertensive medications on lowering blood pressure. Dr Naci is an Assistant Professor of Health Policy at the London School of Economics and Political Science. During the 2018-2019 academic year, he is a UK Harkness Fellow in Health Care Policy and Practice at the Harvard Kennedy School of Government and Harvard Medical School.

He has a PhD in Health Policy from the Department of Social Policy at the LSE and an MHS in International Health from the Johns Hopkins Bloomberg School of Public Health. In this 20 minute conversation, Dr Naci discusses: · The history of antihypertensive medications · Exercise’s effects on blood pressure · The findings of his latest meta-analysis · His 2013 study that compared the effectiveness of pharmacological and non-pharmacological interventions on mortality · The clinical practice and guideline implications of the meta-analysis Further reading: Naci H, Ioannidis JP.

What should we eat in order to stay healthy and avoid disease? Nutrition is one of the biggest drivers of chronic disease, including obesity and diabetes, yet the answer to this seemingly simple question remains a subject of heated debate. On this week’s episode, Dr. Zoë Harcombe (@zoeharcombe) joins BJSM’s Daniel Friedman (@ddfriedman) to address some common nutrition myths. Zoë has a PhD in public health nutrition. The full title of her thesis is: “An examination of the randomised controlled trial and epidemiological evidence for the introduction of dietary fat recommendations in 1977 and 1983: A Systematic Review and Meta-analysis“. She researches in the fields of nutrition, diet, dietary advice, diet-related health and obesity and writes and talks about these topics daily - http://www.zoeharcombe.com/ In this 30 minute conversation, Zoë reviews the evidence supporting commonly held nutrition beliefs and discusses: · Does red and process meat cause cancer? · Should everyone follow a Mediterranean diet? · Are wholegrains healthy? · How many fruit + veg should we be eating daily? · What makes up a nutritious diet?
