MedicalResearch.com Interview with: “Sara Singing for the IT MS Society” by Draft is licensed under PDM 3.0Filippos Filippidis MD, MSc, MPH, PhD Lecturer in Public Health School of Public Health Imperial College London London MedicalResearch.com: What is the background for this study? What are the main findings? Response: Previous research suggests that big sports and international events are associated with happiness, productivity, suicides and homicides. Considering the popularity of the Eurovision Song Contest (ESC) in Europe, we wanted to see if there is any association between performance in the competition and life satisfaction and suicides. We used interview data from more than 160,000 people in Europe collected from 2009 to 2015 and found that better performance in the contest was associated with higher levels of life satisfaction in the country. Winning the competition did not confer any additional advantage. When comparing bad performance in the ESC with no participation at all, we found that even bad performance was associated with higher satisfaction with life compared to absence from the competition.

MedicalResearch.com Interview with: Tove Fall PhD Senior author of the study Associate Professor in Epidemiology Department of Medical Sciences and the Science for Life Laboratory Uppsala University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Loneliness and sedentary lifestyle are two major risk factors for cardiovascular disease and mortality, but are notoriously difficult to prevent in the general population. Previous studies have shown that dogs may serve as a strong motivator for daily exercise, provide substantial social support and have a positive effect on the owner’s gut microbiome. The effects of pet dogs on health outcomes in the general population are largely unknown. (more…)

MedicalResearch.com Interview with: Dr. Karla Galaviz PhD Hubert Department of Global Health Rollins School of Public Health Emory University Sonya Haw, MD| Assistant Professor Division of Endocrinology, Metabolism & Lipids Emory University, School of Medicine Grady Memorial Hospital Atlanta, GA MedicalResearch.com: What is the background for this study? What are the main findings?
  • Diabetes affects 1 in 11 adults worldwide and though there is evidence that lifestyle modification (eating healthier diets and exercising about 150 mins a week) and certain medications can prevent or delay diabetes onset, it is not clear which of these strategies offers long-term benefits.
  • To answer this question, we compiled all available randomized controlled trials of lifestyle programs and medications to prevent diabetes and analyzed the data to see if the diabetes prevention effects persisted in the long-term. We specifically compared studies where the lifestyle or drug interventions were discontinued to see if the effect was long lasting or diminished when the intervention was stopped.

AHA Journals, Author Interviews, Brigham & Women's - Harvard, Exercise - Fitness, Lifestyle & Health / 08.11.2017

MedicalResearch.com Interview with: I-Min Lee, MD, ScD Professor of Medicine, Harvard Medical School Professor of Epidemiology, Harvard T.H. Chan School of Public Health Brigham and Women's Hospital Boston, MA 02215 MedicalResearch.com: What is the background for this study? What are the main findings? Response: The fact that physical activity lowers the risk of premature mortality is not a new fact – we have many studies showing this.  However, previous studies have primarily relied on self-reported physical activity, and self-reports tend to be imprecise.  Based on these self-report studies, we know that physical activity is associated with a 20-30% reduction in mortality rates.  And, these self-report studies also have focused on moderate-to-vigorous intensity physical activity, since they are more reliably reported than lighter intensity activity.  We have little information on whether light-intensity activities (e.g., light household chores, very slow walking such as when strolling and window shopping) are associated with lower mortality rates. We now have “wearables” – devices that can more precisely measure physical activity at low (as well as higher) intensities, and sedentary behavior.  The present study, conducted between 2011 and 2015, investigated a large cohort of older women (n=16,741; mean age, 72 years)  who were asked to wear these devices for a week – thus, providing detailed physical activity and sedentary behavior measures.  During an average follow-up of about two-and-a-half years, 207 women died.  The study confirmed that physical activity is related to lower mortality rates. What is new and important is how strong this association is when we have more precise measures of physical activity – the most active women had a 60-70% reduction in mortality rates, compared with the least active, during the study.  For context, non-smokers have about a 50% risk reduction, compared to smokers, which is why patients (and doctors) should pay attention to being physically active.

MedicalResearch.com Interview with: Olga Theou, MSc PhD Assistant Professor, Department of Medicine, Dalhousie University Affiliated Scientist, Geriatric Medicine, Nova Scotia Health Authority Adjunct Senior Lecturer, School of Medicine, University of Adelaide Halifax, Nova Scotia  MedicalResearch.com: What is the background for this study? What are the main findings? Response: We already know that moderate to vigorous intensity physical activity, such as time accumulated during exercise, is associated with numerous health benefits. More recent studies also have shown that sedentary time, such as time accumulated during prolonged sitting at work, transportation, and leisure, can also increase the risk of adverse outcomes. What was not known was whether prolonged sitting affects people across different levels of frailty similarly. This is what we examined in our study. We found that there were differences. Low frailty levels (people who are extremely healthy; frailty index score < 0.1) seemed to eliminate the increased risk of mortality associated with prolonged sitting, even among people who did not meet recommended physical activity guidelines. Among people with higher frailty levels, sedentary time was associated with mortality but only among those who did not meet recommended physical activity guidelines (more…)
Author Interviews, Education, Heart Disease, JAMA, Lifestyle & Health, Primary Care, UCLA / 28.07.2017

MedicalResearch.com Interview with: Carol M. Mangione, MD, MSPH, FACP Barbara A. Levey, MD, and Gerald S. Levey, MD Endowed chair in medicine David Geffen School of Medicine University of California, Los Angeles Professor of public health at the UCLA Fielding School of Public Health MedicalResearch.com: What is the background for this study? Response: Americans can experience several health benefits from consuming healthy foods and engaging in physical activity. The Task Force recommends that primary care professionals work together with their patients when making the decision to offer or refer adults who are not obese and do not have hypertension, high cholesterol, high blood sugar, or diabetes to behavior counseling to promote healthful diet and physical activity. Our focus was on the impact of a healthful diet and physical activity on cardiovascular risk because this condition is the leading cause of premature morbidity and mortality. The Task Force evaluates what the science tells us surrounding the potential benefits and harms of a particular preventive service. In this case, the Task Force found high quality evidence focusing on the impact a healthful diet and physical activity can have on a patient’s risk of cardiovascular disease. Relying on this evidence, the Task Force was able to conclude that there is a positive but small benefit of behavioral counseling to prevent cardiovascular disease. (more…)

MedicalResearch.com Interview with: Professor Keith A. Wesnes BSc PhD FSS CPsychol FBPsS Head Honcho, Wesnes Cognition Ltd Professor of Cognitive Neuroscience, Medical School, University of Exeter, UK Visiting Professor, Department of Psychology Northumbria University, Newcastle, UK Adjunct Professor, Centre for Human Psychopharmacology, Swinburne University, Melbourne, Australia Visiting Professor, Medicinal Plant Research Group Newcastle University, UK Wesnes Cognition Ltd, Little Paddock, Streatley Hill, Streatley on Thames UK  MedicalResearch.com: What is the background for this study? What are the main findings? Response: This data we reported were taken from the PROTECT study, a 10-year research programme being conducted jointly by Kings College London and the University of Exeter Medical School. It started in November 2015 and over 20,000 individuals aged 50 to 96 years have enrolled. A highly novel feature of the study is that it is run entirely remotely, the participants logging on via the internet at home and providing demographic and life style information, and also performing online cognitive tasks of key aspects of cognitive function. The tasks are from two well-validated systems, CogTrack and the PROTECT test system, and assess major aspects of cognitive function including focused and sustained attention, information processing, reasoning and a range of aspects of memory. One of the lifestyle questions was ‘How frequently do you engage in word puzzles, e.g. crosswords?’ and the 6 possible answers were: never; occasionally; monthly; weekly; daily; more than once per day. We analysed the cognitive data from 17,677 individuals who had answered the question, and found that the more often the participants reported engaging in such puzzles, the better their cognitive function on each of the 9 cognitive tasks they performed. The group who never performed such puzzles were poorest on all measures, and the improvements were mostly incremental as the frequency of use increased. The findings were highly statistically reliable, and we controlled for factors including age, gender and education. To evaluate the magnitudes of these benefits, we calculated the average decline over the age-range on the various tasks in the study population. The average difference between those who ‘never’ did puzzles to those who did so ‘more than once a day’ was equivalent to 11 years of ageing; and between those who never did puzzles and all those who did was 8 years.

Author Interviews, Brigham & Women's - Harvard, Lifestyle & Health, NEJM, Nutrition / 13.07.2017

MedicalResearch.com Interview with: Mercedes Sotos Prieto PhD Research Fellow Department of Nutrition Harvard T. H. Chan School of Public Health MedicalResearch.com: What is the background for this study? What are the main findings? Response: Previous research have found that adherence to the 2010 Alternate Heathy Eating Index, the Mediterranean Diet pattern, and DASH pattern is associated with health benefits, but none of those studies have examined dynamic changes in diet quality over time and subsequent risk of mortality. This is the first study to demonstrate that improvement in these three diet scores over time is associated with reduced risk of total and cardiovascular mortality. In contrast, worsening diet quality over 12-years was associated with 6%-12% increased mortality. In addition, not only improvement in diet quality but maintaining a high adherence to any of the three dietary patterns over 12 years was significantly associated with 9%-14% lower total mortality.

MedicalResearch.com Interview with: Ivana Buric Brain, Belief, and Behaviour Lab Centre for Psychology, Behaviour, and Achievement, Faculty of Health and Life Sciences Coventry University, Coventry, United Kingdom Donders Institute for Brain, Cognition and Behaviour Radboud University, Nijmegen, Netherlands MedicalResearch.com: What is the background for this study? What are the main findings? Response:  Genes that we inherited can change their activity - the​y can be active and produce proteins, but they can also stop producing proteins and remain silent. We are now beginning to understand what aspects of our environment affect the activity of which genes. In this study, we analysed all the existing studies that examined the effects of mind-body interventions on the expression of our genes and found that mind-body techniques reduce the activity of genes that produce inflammatory proteins. This pattern was found in all studies despite the fact that they vary in the amount of physical activity: Tai Chi, yoga, breathing techniques and different types of meditation. We believe that this effect is observed due to reduced stress. When we experience something stressful, the brain regions associated with pain get activated and send that signal further to sypmathetic nervous system that produces epinephrine and norepinefrine, and activates nuclear factor kappa B - a molecule that travels to and activated the genes that produce inflammatory proteins. When we do yoga or meditation, we learn to perceive situations differently and consequently experience less stress, which then prevents the production of inflammatory proteins. (more…)

MedicalResearch.com Interview with:   Professor Helena Teede MBBS, FRACP, PhD Executive Director Monash Partners Academic Health Research Translation Centre Director Monash Centre for Health Research and Implementation Monash University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Reproductive aged women are gaining weight rapidly both before and during pregnancy. Here in 1.3 million pregnancies internationally we show that almost 3 in 4 have unhealthy weight gain (half with excess weight gain and one quarter with inadequate gain) MedicalResearch.com: What should readers take away from your report? Response: For women establish your healthy weight for your height and try to stay within this for better fertility, pregnancy and for your and your child's health. Regardless of your starting weigh,  aim to gain within targets in pregnancy. Seek help to do so. For health professionals: unhealthy weight gain in pregnancy is now the norm, we must monitor women in pregnancy wand support them to gain healthy weight for better health outcomes. Weighing is not enough with health professionals needing skills in healthy conversations and support strategies for women. For governments and policy makers this life stage around pregnancy is an optimal time to tackle obesity prevention and is targeted by WHO. (more…)
Addiction, Author Interviews, Lifestyle & Health, Occupational Health / 04.04.2017

MedicalResearch.com Interview with: Jaana Halonen, Docent and Senior Researcher Finnish Institute of Occupational Health MedicalResearch.com: What is the background for this study? Response: Retirement is a significant life transition when substantial changes in daily life are experienced as retirees adapt to life without work. After retirement people have more leisure time and more opportunities for different activities, and less stress. These changes are positive, but retirement can also lead to reduced social control and loss of social contacts and therefore be perceived as a stressful life transition. Both the positive and negative aspects related to changes in leisure time, stress, and social networks around retirement may affect drinking behaviours. However, little is known about how risky alcohol consumption changes around the retirement transition. Thus, in our study we wanted to examine how and for whom risky drinking changes around the time of retirement. To do that we followed up public sector workers with questionnaires before and after their old-age retirement. (more…)
Author Interviews, Lifestyle & Health, Weight Research / 23.03.2017

MedicalResearch.com Interview with: Jill Gonzalez WalletHub Analyst MedicalResearch.com: What is the background for this study? What are the main findings? Response: We based our research on recent findings that suggest that 70 percent of the adult U.S. population is overweight or obese. With that in mind, we wanted to find which metro areas offer the best environments for a healthy and active lifestyle. Based on the report's methodology, we concluded that areas in the south tend to have higher overweight and obese rates, as some fail to offer residents healthy environments and amenities that would facilitate a more active lifestyle. Please find the report's main findings here: https://wallethub.com/edu/fattest-cities-in-america/10532/#main-findings. (more…)

MedicalResearch.com Interview with: Andrew T. Yan, MD Terrence Donnelly Heart Centre St Michael's Hospital University of Toronto Toronto, Ontario, Canada MedicalResearch.com: What is the background for this study? What are the main findings? Response: The pathogenesis of aortic stenosis is complex and incompletely understood. Previous experimental data and epidemiologic studies (mostly cross-sectional) have demonstrated an association between conventional cardiovascular risk factors such as hypertension, diabetes, and dyslipidemia, and aortic sclerosis or stenosis. However, there is a paucity of longitudinal data from large population studies. Therefore, we sought to examine the relationship between conventional cardiovascular risk factors and incident severe aortic stenosis during extended follow-up in a large unselected elderly population in Ontario, Canada. In over 1 million individuals older than 65 who were followed for a median of 13 years, hypertension, diabetes and dyslipidemia were all significantly and independently associated with development of severe aortic stenosis requiring hospitalization or intervention. Furthermore, we observed a positive dose-response relationship between the number and duration of cardiac risk factors, and the risk of aortic stenosis. Together, these risk factors accounted for approximately one third of the incidence of severe aortic stenosis at a population level. (more…)

MedicalResearch.com Interview with: Lu Qi, MD, PhD, FAHA HCA Regents Distinguished Chair and Professor Director, Tulane University Obesity Research Center Department of Epidemiology Tulane University School of Public Health and Tropical Medicine New Orleans, LA 70112  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Adherence to healthy lifestyle (high physical activity, less smoking, moderate alcohol consumption, healthy diet, and low adiposity) has been related to substantially reduced risk of cardiovascular diseases in large cohorts from the US and Europe, however, similar evidence in Asians such as Chinese is lacking.

MedicalResearch.com Interview with: Ellen Warner, MD, FRCPC, FACP, M.Sc. Affiliate scientist Sunnybrook Health Sciences Centre Toronto, ON MedicalResearch.com: What is the background for this review? Response: As a medical oncologist who has treated breast cancer patients for over 30 years, I have found that most of the women in my practice are desperately looking for things they can do beyond standard surgery, radiation, chemotherapy, etc. to increase their chance of cure.  Unfortunately, many fall prey to false claims they read over the Internet or hear from well-meaning friends and relatives.  As a result they turn to absurdly restrictive diets (eg. No meat, dairy or sugar) or to ‘supplements’ with unproven effectiveness or even safety. So I thought it would be helpful to review the literature to determine what evidence-based lifestyle changes these women could make that would at least improve their overall health and, ideally, reduce their risk of dying of recurrent breast cancer.  For this review I thought it would be great to team up with Julia Hamer, a pre-med student with a degree in nutrition who just happens to also be an Olympic level athlete!

MedicalResearch.com Interview with: Arch G. Mainous III, PhD HSRMP Department Chair Florida Blue Endowed Professor of Health Administration University of Florida Health MedicalResearch.com: What is the background for this study? Response: As our post-industrial society becomes more and more sedentary, there is a concern that a lack of activity is associated with poor health outcomes like diabetes. At the same time, the medical community has a strong focus on determining whether patients are overweight or obese as a way to classify them as  being at higher risk for poor health outcomes. However, individuals at a “healthy weight” in general, are considered to be at low risk. Some recent studies have shown that many individuals at “healthy weight” are not metabolically healthy. How then might we predict who at “healthy weight” would be unhealthy? We hypothesized that individuals at “healthy weight” who had a sedentary lifestyle would be more likely to have prediabetes or undiagnosed diabetes. (more…)

MedicalResearch.com Interview with: Bernard M Duvivier  Department of Human Biology and Movement Science NUTRIM School for Nutrition and Translational Research in Metabolism, Maastricht University Medical Centre Maastricht, the Netherlands MedicalResearch.com: What is the background for this study?  What are the main findings? Response: The health benefits of exercise have been well established but sitting is a risk factor for health, independent of exercise. As many people with type 2 diabetes don’t like to exercise we investigated whether replacing sitting time with light-intensity activities (standing and light walking) is equally effective to exercise when energy expenditure is comparable. Our results suggest that for people with type 2 diabetes, light-intensity activities (light walking and standing) can be an alternative to exercise to improve glucose regulation. In addition we showed that too much sitting has negative effects on insulin sensitivity which could not be fully compensated by 1 hour of exercise per day. (more…)
Author Interviews, Dermatology, Lifestyle & Health / 18.11.2016

MedicalResearch.com Interview with: Luigi Naldi, MD Director Centro Studi GISED Department of Dermatology Azienda Ospedaliera papa Giovanni XXIII Bergamo Italy MedicalResearch.com: What is the background for this study? What are the main findings? Response: The study was the natural continuation of a previous case-control study focusing on risk factors for moderate to severe acne in adolescents. In that study, we documented the role of a westernized diet to influence acne severity, with a low weekly intake of fruits or vegetables, a low consumption of fresh fish and a high consumption of milk especially skim milk, being risk factors for moderate to severe acne. Not surprisingly, also a family history of acne was associated with acne severity. After completion of our study in adolescents, we realized that very little was known about acne in adults. Hence, we started a new case-control study focusing on risk factors for adult female acne. Besides the role of a family history, we documented that lifestyle factors could play an important role in adult acne. More specifically, being an office worker, and having a high level of reported psychological stress were associated with acne in adult women. In addition, similarly to acne in adolescents, low weekly intake of fruits or vegetables and a low consumption of fresh fish were documented as risk factors. It is important to find the reason for your acne. But it is also important to know that there is pretty much always a solution to dealing with this. It is understandable that many people find it hard to deal with, but it is something that you shouldn't let ruin your life. If you are someone who suffers with acne and are not sure on what the next steps are to help manage this effectively, it might be in your best interest to look into something like a cbd pure review from companies such as HerbMighty. You might be able to find the answers that you have been looking for when it comes to your acne. (more…)
Author Interviews, Emory, Exercise - Fitness, Geriatrics, Heart Disease, Lifestyle & Health / 18.11.2016

MedicalResearch.com Interview with: Vasiliki Georgiopoulou MD MPH PhD Assistant Professor of Medicine (Cardiology) Emory University School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: Although existing evidence suggests that more exercise capacity is associated with lower risk of CV disease and death, we don’t know whether more exercise capacity would lead to lower risk for heart failure also. This would be especially important for older adults, who are the group with the highest risk to develop heart failure. We used the data of a cohort study to test this association. The exercise capacity was evaluated by a walking test that is easy to perform – the long-distance corridor walk test. We observed that older adults who were able to complete the test had the lowest risk to develop heart failure and the lowest mortality rates, when compared with those who were not able to complete the test and those who could not do the test for medical reasons. We also observed that changes in exercise capacity 4 years later did not predict subsequent heart failure or mortality – perhaps because less fit older patients had already developed heart failure or had died.

MedicalResearch.com Interview with: Ulrik Wisløff, PhD Professor, Head of K.G. Jebsen Center for Exercise in Medicine Department of Circulation and Medical Imaging Norwegian University of Science and Technology Norway MedicalResearch.com: What is the background for this study? What are the main findings? Response: Prolonged time spent sedentary on a daily basis is detrimental for general health and is associated with increased risk of developing and dying from lifestyle related diseases such as cardiovascular disease – even in those following todays advice for physical activity given by health authorities worldwide. Number of hours spent inactive tend to increase with increased age. A person’s fitness level is regarded the best predictor of future health. We tested, in older adults (aged 70-77 years old) whether meeting physical activity recommendations and/or having high age-specific fitness level attenuated the adverse effect of prolonged sedentary time on cardiovascular risk factor clustering. Main finding was that high age-specific fitness level fully attenuated the adverse effect of prolonged sedentary time on clustering of cardiovascular risk factors, independent of meeting the physical activity recommendation in older adults.

MedicalResearch.com Interview with: Paul Dinneen Loprinzi, PhD Health, Exercise Science and Recreation Management University of Mississippi MedicalResearch.com: What is the background for this study? What are the main findings? Response: Previous research demonstrates that adults who have higher daily sedentary behavior tend to have worse cardiometabolic health profiles. The extent to which sedentary behavior is associated with diabetic retinopathy has yet to be evaluated in the literature before our study. Our findings provided some suggestive evidence that more sedentary behavior was associated with a higher odds of having diabetic retinopathy. (more…)

MedicalResearch.com Interview with: Ulf Ekelund, PhD FACSM Professor Department of Sports Medicine Norwegian School of Sport Sciences  MedicalResearch.com: What is the background for this study? What are the main findings? Response: It is known that long sitting hours may be detrimental to health and previous studies have suggested associations between sitting time and all-cause mortality.However, it is not known whether physical activity can eliminate the increased risk of death associated with long sitting time. We found that at least one hour of physical activity every day appear to offset the increased risk associated with more than eight hours of sitting. We also found that those who were physically inactive and sat for less than 4 hours every day were at greater risk compared with those who were physically active and sat for more than 8 hours providing further evidence on the benefits of physical activity.

MedicalResearch.com Interview with: Ding Ding (Melody), Ph.D., MPH NHMRC Early Career Senior Research Fellow Sydney University Postdoctoral Research Fellow Prevention Research Collaboration Sydney School of Public Health The University of Sydney MedicalResearch.com: What is the background for this study? Response: Understanding the true burden of a pandemic is indispensable for informed decision making. After decades of research, we now have established knowledge about how physical inactivity contributes to pre-mature deaths and chronic diseases, but the economic burden of physical inactivity remains unquantified at the global level. Through estimating the economic burden of physical inactivity for the first time, we hope to create a business case for investing in cost-effective actions to promote physical activity at the global levels.

MedicalResearch.com Interview with: Joshua J. Joseph, MD Christopher D. Saudek M.D. Fellow in Diabetes Research Division of Endocrinology, Diabetes and Metabolism Johns Hopkins University School of Medicine MedicalResearch.com: What does your study explore? Response: Our study explores two basic questions: (a) Are multi-ethnic people with higher levels of cardiovascular health less likely to develop diabetes based on the AHA ideal cardiovascular health metric? (b) Do these associations vary by race/ethnicity (non-Hispanic white, Chinese American, African American, and Hispanic American)? MedicalResearch.com: Why did you choose this topic to explore? Response: The literature has shown a strong association between lifestyle factors and elevated risk of diabetes in majority non-Hispanic white studies. One study of American Indians showed that meeting a greater number of ideal cardiovascular health goals was associated with a reduced risk of diabetes. We aimed to assess the association of baseline ideal cardiovascular health with incident diabetes within a multi-ethnic population, due to variation of ideal cardiovascular health by race/ethnicity.

MedicalResearch.com Interview with: David Earnest, Ph.D. Professor in the Department of Neuroscience and Experimental Therapeutics Texas A&M Health Science Center College of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Earnest: When body clocks are disrupted, as they are when people engage in shift work or go to bed and get up at radically different times every few days, more severe ischemic strokes can result. MedicalResearch.com: What should readers take away from your report? Dr. Earnest:  Whenever possible, go to bed and get up at the same time each day and keep regular mealtimes. If you do need to keep an irregular schedule, it is especially important to be mindful of stroke risk and try especially hard to eliminate other risk factors, such as hypertension and obesity.

MedicalResearch.com Interview with: Steven C. Moore PhD, MPH Division of Cancer Epidemiology and Genetics Rockville, MD  MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Moore: More than half of Americans fail to meet recommended levels of regular physical activity; physical inactivity has become a major public health concern. Physical activity during leisure time is known to reduce risks of heart-disease and all-cause mortality, as well as risks of colon, breast, and endometrial cancers. However, less is known about whether physical activity reduces risk of other cancers. Hundreds of prospective studies have examined associations between physical activity and risk of different cancers. Due to small case numbers, results have been inconclusive for most cancer types. In this study, we examined how leisure-time physical activity relates to risk of 26 different cancer types in a pooled analysis of 12 prospective cohort studies with 1.44 million participants. Our objectives were to identify cancers associated with leisure-time physical activity, and determine whether associations varied by body size and/or smoking history. (more…)
Author Interviews, Brigham & Women's - Harvard, Cancer Research, JAMA, Lifestyle & Health / 23.05.2016

MedicalResearch.com Interview with: Mingyang Song
Research Fellow
Department of Nutrition
Harvard T.H. Chan School of Public Health  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Although substantial data support the importance of lifestyle factors for cancer risk, a study published in Science early last year “led some to conclude that only a third of the variation in cancer risk among tissues is attributable to environmental factors or inherited predispositions, while most is due to random mutations arising during stem cell divisions, so-called bad luck.” That study “has been widely covered by the press and has created confusion for the public regarding the preventability of cancer.” In response to that study, we conducted this study to estimate how many cancer cases and deaths in the US can be potentially attributed to common lifestyle factors. Our study showed that about 20-30% of cancer incidences and 40-50% of cancer deaths may be avoided if everyone in the US adopted a lifestyle pattern that is characterized by “never or past smoking (pack-years <5), no or moderate alcohol drinking ([1]1 drink/d for women,[1]2 drinks/d for men), BMI of at least 18.5 but lower than 27.5, and weekly aerobic physical activity of at least 75 vigorous-intensity or 150 moderate-intensity minutes”.
