MedicalResearch.com Interview with: Marcel den Hoed, PhD Researcher,Department of Immunology, Genetics and Pathology Uppsala University MedicalResearch.com: What is the background for this study? What are the main findings? Response: In this paper we performed a multi-ancestry meta-analysis of 51 genome-wide association studies, in data from over 700,000 individuals. This yielded 11 DNA regions that are robustly associated with self-reported moderate-to-vigorous intensity physical activity during leisure time (MVPA), and 88 DNA regions for self-reported leisure screen time (LST). Around half of the identified DNA regions are also associated with objectively assessed physical activity traits in data from the UK Biobank. Causal inference using a Mendelian randomization approach subsequently showed bidirectional causal effects between LST and body mass index (BMI), with the effect of LST on BMI being 2-3-fold larger than vice versa. Less LST and more MVPA protect from diabetes, attention deficit hyperactivity disorder, depression, and earlier age at death, with all causal effects of MVPA and leisure screen time being mediated or confounded by BMI. Further analyses showed that DNA regions associated with LST are more often located close to genes whose expression in skeletal muscle is altered by strength training than expected by chance, suggesting that these genes may influence the likelihood of adopting an active lifestyle by influencing the response to training.

MedicalResearch.com Interview with:

Lori Pbert, Ph.D Professor, Department of Population and Quantitative Health Sciences Associate chief of the Division of Preventive and Behavioral Medicine Founder and director of the Center for Tobacco Treatment Research and Training University of Massachusetts Chan Medical School Dr. Pbert joined the U.S. Preventive Services Task Force in January 2019

MedicalResearch.com: What is the background for this study? What are the main findings?

 

Response: Heart attacks and strokes are the number one killer of adults in the United States. Based on the evidence we reviewed, the Task Force found that some people would benefit from counseling interventions to support their cardiovascular health, however the overall benefits are small. For that reason, we continue to recommend that healthcare professionals decide together with their patients who do not have cardiovascular disease risk factors whether counseling interventions on healthy diet and physical activity might help them prevent heart attacks and strokes. This is a C grade recommendation. (more…)

Lifestyle & Health / 08.11.2021

Why Early Detection is a Life-saverIt's understandable if you fear visiting the hospital if you feel unwell. You worry that you will get a terrible diagnosis. You would rather pretend that everything is okay than face the truth. Remember that it's better to have early detection of an illness than waiting until everything is late. People's lives were saved because they decided to ask for medical advice early. You can begin your path to recovery Just because you received an unfavorable diagnosis doesn't mean your life is over. Even some life-threatening conditions like cancer already have a cure. Many people underwent remission after months or years of treatment. If you decide against getting medical advice, these potential cures might not work anymore. You will regret not starting the process earlier on. (more…)

MedicalResearch.com Interview with: Dr. John Epling, M.D., M.S.Ed Professor of family and community medicine Virginia Tech Carilion School of Medicine in Roanoke, VA. Medical director of research for family and community medicine Medical director of employee health and wellness for the Carilion Clinic Dr. Epling joined the U.S. Preventive Services Task Force in January 2016. MedicalResearch.com: What is the background for this study? What are the main findings? Response: Cardiovascular disease, which includes heart disease and stroke, is one of the leading causes of death in the United States. Nearly half of all adults have at least one risk factor for cardiovascular disease. Evidence shows that counseling aimed at helping people improve their diet and increase their physical activity can help prevent cardiovascular disease. This typically involves a trained counselor who provides education, helps people set goals, shares strategies, and stays in regular contact.  The Task Force recommends behavioral counseling interventions that promote a healthy diet and physical activity to help people at risk for cardiovascular disease stay healthy.

Author Interviews, Brigham & Women's - Harvard, Heart Disease, JAMA, Lifestyle & Health, Nutrition / 26.10.2020

MedicalResearch.com Interview with: Samia Mora, MD MHS Associate Professor, Harvard Medical School Director, Center for Lipid Metabolomics Brigham and Women’s Hospital Boston, MA 02215 @SamiaMoraMD MedicalResearch.com: What is the background for this study? Response: Couples, both married couples and domestic partners, are likely to share similar environmental exposures, adopt similar behavior patterns, and have similar characteristics. However, the degree to which couples share similar levels of cardiovascular (CV) risk factors and behaviors is uncertain. If high levels of poor CV risk factor measures and behaviors are common in both members of a couple, programs that target improvement of these risk factors and behaviors may simultaneously benefit CV health in both members of the couple.

Author Interviews, Lifestyle & Health, PNAS, Psychological Science, University Texas / 31.07.2019

MedicalResearch.com Interview with: John M. Griffin PhD James A. Elkins Centennial Chair in Finance McCombs School of Business The University of Texas  MedicalResearch.com: What is the background for this study? What are the main findings? Response: The importance of personal traits compared to context for predicting behavior is a long-standing issue in psychology. Yet, we have limited evidence of how predictive personal conduct, such as marital infidelity, is for professional conduct. We use data on usage of a marital infidelity website as a measure of marital infidelity and find that it is strongly correlated with professional conduct in four different professional settings.

MedicalResearch.com Interview with: Wei Bao, MD, PhD Assistant Professor, Department of Epidemiology College of Public Health, University of Iowa Iowa City, IA 52242  and Yang Du University of Iowa MedicalResearch.com: What is the background for this study? Response: In 2008, the US Department of Health and Human Services released the first federal Physical Activity Guidelines for Americans, which recommended that people should do at least 150 minutes moderate- to vigorous-intensity aerobic activity. This key recommendation has been reaffirmed in the 2018 recently updated Physical Activity Guidelines for Americans. In addition, the new 2018 Guidelines for the first time discussed health risks of sedentary behaviors. Insufficient physical activity and long sitting time have long been recognized as risk factors for major chronic diseases and mortality. Therefore, we were curious whether there have been a significant changes in adherence to the Physical Activity Guidelines in US adults since the release of the first edition of the federal guidelines in 2008 and whether sedentary behavior in US adults changed during the same period.

Author Interviews, Lifestyle & Health, Mental Health Research, Opiods, University of Pennsylvania / 15.07.2019

MedicalResearch.com Interview with: Samuel Preston, Ph.D. Professor of Sociology University of Pennsylvania MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Life expectancy at birth in the United States is low by international standards and has been declining in recent years. Our study aimed to identify how these trends differed by age, sex, cause of death, metropolitan status, and region. We found that, over the period 2009-11 to 2014-16, mortality rose at ages 25-44 in large metropolitan areas and their suburbs as well as in smaller metropolitan areas and non-metropolitan areas. Mortality at ages 45-64 also rose in all of these areas except large metropolitan areas. These were the ages responsible for declining life expectancy. Changes in life expectancy were particularly adverse for non-metropolitan areas and for women. The metropolitan distinctions in mortality changes were similar from region to region. The cause of death contributing most strongly to mortality declines was drug overdose for males and mental and nervous system disorders for women. (more…)
Author Interviews, Exercise - Fitness, Lifestyle & Health, Weight Research / 16.05.2019

MedicalResearch.com Interview with: sneakers-walkingFrancesco Zaccardi, MD, PhD Clinical Epidemiologist Assistant Director Leicester Real World Evidence Unit Leicester Diabetes Centre UK MedicalResearch.com: What is the background for this study? Response: The role of excess body weight on mortality has been extensively investigated during the last decades. Studies from several countries have also shown, however, that the risk of death in persons who are overweight or obese is lower if their fitness, a parameter indicating cardio-pulmonary health, is higher. Most of these studies reported the beneficial effect of fitness in terms of relative risk reduction, for example 20% reduction of risk of death. Relative estimates, though, are difficult to interpret. (more…)
Alcohol, Author Interviews, Hepatitis - Liver Disease, Lifestyle & Health, Sugar / 25.04.2019

MedicalResearch.com Interview with: E. van Eekelen, MSc | PhD Candidate Leiden University Medical Center Dept. Clinical Epidemiology Leiden, The Netherlands MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Fatty liver, defined as excess accumulation of fat within the liver, covers a broad clinical spectrum and is the leading cause of chronic liver diseases. It has also been linked to type 2 diabetes and cardiovascular disease. The consumption of alcohol is a well-established risk factor for fatty liver. However, we hypothesized that consumption of non-alcoholic energy-containing beverages also leads to liver fat accumulation. We analysed data from the Netherlands Epidemiology of Obesity (NEO) study, which is a prospective population-based cohort study including non-invasive measurements of liver fat content by magnetic resonance spectroscopy. Besides consumption of alcoholic beverages, sugar sweetened beverages were associated with more liver fat. We specifically showed that replacement of alcoholic beverages with milk was associated with less liver fat, whereas replacement with sugar sweetened beverages was associated with a similar amount of liver fat, even when taking calories into account.  (more…)

MedicalResearch.com Interview with: Heli Virtanen, PhD Student University of Eastern Finland  MedicalResearch.com: What is the background for this study? Response: Optimal amount of protein in diet for supporting longevity is unclear. In addition, there have been indications that different protein sources have differential associations with mortality risk.  Thus, we investigated the associations of proteins and protein sources with mortality risk in the Finnish men of the Kuopio Ischaemic Heart Disease Risk Factor Study.

Aging, Author Interviews, Cognitive Issues, Lifestyle & Health / 13.04.2019

MedicalResearch.com Interview with: Carla R. Schubert, MS Researcher,  EpiSense Research Program Dept. of Ophthalmology & Visual Sciences School of Medicine and Public Health University of Wisconsin Madison, WI  53726-2336  MedicalResearch.com: What is the background for this study? Response: Mildlife is an important time-period for health later in life and also when declines in sensory and cognitive functions may begin to occur. Hearing, vision and smell impairments have been associated with cognitive impairments in older adults and with worse cognitive function in middle-aged adults.  These associations may be reflecting the close integration of sensory and cognitive systems as both require good brain function.

Author Interviews, Diabetes, Exercise - Fitness, JAMA, Lifestyle & Health, Weight Research / 05.03.2019

MedicalResearch.com Interview with: Giuseppe Pugliese, MD, PhD for the Italian Diabetes and Exercise Study 2 (IDES_2) Investigators Department of Clinical and Molecular Medicine ‘‘La Sapienza’’ University Diabetes Unit, Sant’Andrea University Hospital Rome, Italy MedicalResearch.com: What is the background for this study? Response: There is a growing epidemic of obesity and type 2 diabetes worldwide, which are causally related to the increasing prevalence of “physical inactivity”, i.e., an insufficient amount of moderate-to-vigorous physical activity according to current guidelines, and “sedentariness”, i.e., too many hours, especially if uninterrupted, spent in a sitting or reclined position.  These two unhealthy behaviors exert their detrimental effects independently of each other and are very common among people suffering from type 2 diabetes, who would therefore benefit from increasing physical activity and reducing sedentary time, as recommended by current guidelines. However, such a behavior change is generally difficult for a number of internal and external barriers and requires behavioral interventions targeting both physical activity and sedentary habits.  Unfortunately, there is no definitive evidence that this is indeed feasible and, particularly, that, if adopted, change in behavior can be maintained in the long term.  (more…)
Author Interviews, Heart Disease, JAMA, Lifestyle & Health, Nutrition / 26.11.2018

MedicalResearch.com Interview with: Ravi B. Patel, MD Division of Cardiology, Department of Medicine Northwestern University Feinberg School of Medicine Chicago, Illinois MedicalResearch.com: What is the background for this study? What are the main findings? Response: The digital attention of scientific articles can be readily quantified using the Altmetric score. The Altmetric score is a weighted measure, incorporating a variety of media platforms. We aimed to characterize the Top 10% of articles by Altmetric score among 4 major cardiovascular journals (Circulation, European Heart Journal, Journal of the American College of Cardiology, and JAMA Cardiology) in 2017. Our primary findings were: 1) nearly half of the most disseminated articles were not original research investigations, 2) the most common article topic was nutrition/lifestyle, and 3) there was a weak but significant correlation between Altmetric scores and citation number.  (more…)

This study describes sitting time and leisure-time physical activity reported by US adults in a national survey. (more…)
Author Interviews, Gender Differences, Lifestyle & Health / 15.11.2018

MedicalResearch.com Interview with: "Blood pressure check" by Army Medicine is licensed under CC BY 2.0Pallavi Bhandarkar MPH Nova Southeastern University Kirkland, Washington preetipshenoy@gmail.com  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Gender based preventative health has been of interest to medical community since 1900’s with health disparities between males and females being of particular interest. United States founded National Research Institutes for female health in 1900. This led to comprehensive and systematic medical services being offered which have improved female health care significantly. Similar research programs and initiatives to improve men’s health were started only in 2000 (1). Cultural depiction of men being fearless and based on perception of masculinity leads them to underutilize the preventative health care screenings available to them or sometimes even delay care when they need it the most. Males have been found to have higher mortality rates compared to females. Life expectancy for females was 5.0 years higher than for males. The difference in life expectancy between the sexes has narrowed since 1979, when it was 7.8 years, but it increased 0.2 year in 2016 from 2015, the first increase since 1990. Death rates for males increased significantly for age groups 15–24, 25–34, 35–44, and 55–64. Rates decreased significantly for age groups 75–84 and 85 and over” (2) My research study adopted the basic survey design and conducted an anonymous survey throughout United States with men aged 18 to 40 being the participants. Our goal was to identify these gaps, analyze the reasons for underutilization and identify opportunities to improve preventative care guidelines among the male population. The main findings were almost similar to the BFRSS data obtained by CDC in the year 2016. (more…)
Author Interviews, Heart Disease, Lifestyle & Health, Yale / 11.11.2018

MedicalResearch.com Interview with: Nikolaos Papoutsidakis, M.D., Ph.D. Associate Research Scientist, Yale University School of Medicine New Haven, CT  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Lifestyle education is a significant part of Hypertrophic Cardiomyopathy management. HCM patients, who frequently have to abstain from intense athletics, often ask if such restrictions extend to thrill-seeking activities they previously enjoyed, such as rollercoaster rides. Werealized there is very little data on this topic, which prompted us to set up this study. We found that for Hypertrophic Cardiomyopathy patients who elected to participate in thrill-seeking activities, adverse events (defined as losing consciousness or experiencing a shock from an implantable cardioverter-defibrillator) were rare. We also asked patients (participating and non participating) about advice received from their physician on this topic. We found that, probably due to the lack of data, physicians often avoid providing advice or provide conflicting advice regarding participation in thrill seeking activities.  (more…)
Author Interviews, BMJ, Exercise - Fitness, Lifestyle & Health / 13.10.2018

MedicalResearch.com Interview with: Dr Fehmidah Munir CPsychol, AFBPsS Reader in Health Psychology Athena SWAN School Champion School of Sport, Exercise & Health Sciences National Centre for Sports and Exercise Medicine Loughborough University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Given the evidence of the harmful effects of high levels of sitting time on health and the high proportion of time the majority of adults spend in this behaviour, particularly in the workplace, methods to reduce overall and prolonged sitting were needed. Our SMArT Work (Stand More AT Work) programme was delivered to NHS office workers and involved brief education about the impact of sitting on health and benefits of reducing sitting, feedback on sitting behaviour, providing staff with a height-adjustable desk to enable them to work either standing up or sitting down, motivational posters and brief chats with a researcher to see how they were getting on. They received this programme over 12 months. We found that office workers in our study spent nearly 10 hours/day sitting down, which can be bad for health, but we’ve shown that those office workers who received our SMArT Work programme had lower sitting time by around 80mins per day after 12 months compared to those who didn’t receive our programme. Those who received SMArT Work also reported an increase in work engagement, job performance and quality of life and less musculoskeletal issues such as back and neck pain, they felt less tired after a day at work, had less feelings of anxiety and lower sickness presenteeism (working whilst sick). We didn’t find any differences in the number of days absent at work though. Whether you work remotely from home or in an office environment, it may also be good to invest in new Office Furniture. This could also help combat the issue of back and neck pains that you may be experiencing. (more…)
Author Interviews, Exercise - Fitness, Lifestyle & Health / 18.09.2018

MedicalResearch.com Interview with: “sleeping” by Venturist is licensed under CC BY 2.0Matthieu Boisgontier  PhD Movement Control & Neuroplasticity Research Group KU Leuven Brain Behaviour Laboratory University of British Columbia, Canada MedicalResearch.com: What is the background for this study? What are the main findings? Response: For decades, society has encouraged people to be more physically active. Yet, despite gradually scaling up actions promoting physical activity across the years, we are actually becoming less active. From 2010 to 2016, the number of inactive adults has increased by 5% worldwide, now affecting more than 1 in 4 adults (1.4 billion people). This context raised the question: Why do we still fail to be more physically active? Our hypothesis was that this failure is explained by an “exercise paradox” in which conscious and automatic processes in the brain come into conflict. To illustrate this paradox, you can think of people taking the elevator or escalator when they go to the gym, which does not make sense. This non-sense, this paradox, could be due to the fact that their intention to exercise come into conflict with an automatic attraction to resting in the elevator. (more…)
Author Interviews, CMAJ, Heart Disease, Lifestyle & Health, Stroke / 23.07.2018

MedicalResearch.com Interview with: Dr. Doug Manuel MD, MSc, FRCPC Professor and Senior Scientist Ottawa Hospital Research Institute | L’Institut de Recherche de l’Hôpital d’Ottawa Department of Family Medicine, University of Ottawa Départment de Médicine Familiale Université d’Ottawa  MedicalResearch.com: What is the background for this study? What are the main findings? Response: A lot of people are interested in healthy living, but often we don't have that discussion in the doctor's office," says Dr. Manuel, who is also a professor at the University of Ottawa. "Doctors will check your blood pressure and cholesterol levels, but they don't necessarily ask about lifestyle factors that could put you at risk of a heart attack and stroke. We hope this tool can help people — and their care team — with better information about healthy living and options for reducing their risk of heart attack and stroke." "What sets this cardiovascular risk calculator apart is that it looks at healthy living, and it is better calibrated to the Canadian population," says Dr. Doug Manuel, lead author, senior scientist at The Ottawa Hospital and a senior core scientist at the Institute for Clinical Evaluative Sciences (ICES).”  (more…)

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…)
Author Interviews, Diabetes, JAMA, Lifestyle & Health / 09.11.2017

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.
