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.

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).”  Continue reading

Bad Genes and Unhealthy Lifestyle Contribute to Cardiovascular Risk

Pim van der Harst MD, MSc
Professor and Scientific Director Cardiac Catheterization Laboratory

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

Response: Cardiovascular disease is the leading cause of morbidity and mortality worldwide. The disease is driven by both genetic (inherited) and lifestyle factors such as smoking, physical activity and body mass index (BMI).

However, little is known about the interplay between genetic and lifestyle factors. So we looked into how lifestyle influences risk in individuals with a low genetic risk compared to those with a high genetic risk.

 

MedicalResearch.com: What are the main findings?

Response: We studied 339,003 unrelated individuals participating in UK Biobank project and looked into 5 very important cardiovascular conditions: coronary artery disease, atrial fibrillation, stroke, hypertension and type 2 diabetes.

We then calculated the genetic risk of these individuals bases on the DNA information and assessed their lifestyle. We found that both genetics and an unhealthy lifestyle increased the risk of developing these conditions in an additive way.

Risk appears simply as a summation of bad genes and an unhealthy lifestyle, there is no multiplier effect. A healthy lifestyle is always beneficial, independent of the luck you had with your genes. However, we do see patterns suggesting that for some conditions the risk is approximately the same for those with good genes and poor lifestyle compared to those with poor genes and a poor lifestyle. Best is to have both, good genes and a healthy lifestyle. 

MedicalResearch.com: What should readers take away from your report?

Response: No matter how good your genes are, a good lifestyle is always beneficial. However, if you have a high genetic risk you really should pay even more attention an adhering to a healthy lifestyle, otherwise they are in double trouble. Also our study is important as it lays a foundation for personalized risk assessment. 

MedicalResearch.com: What recommendations do you have for future research as a result of this work?

Response: Now we can combine the personal genetics with a person’s lifestyle we should work towards personalized risk assessment and estimate the effect of lifestyle changes for an individual.

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.

Healthy Lifestyle Keys to a Longer Life

MedicalResearch.com Interview with:
Yanping Li PhD, Research Scientist
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: It is well known that a  healthy lifestyle is associated with less chance of premature mortality; however, it is not clear how much it will improve the longevity.

We are working on a quantity estimation of the prolonged life expectancy that could be potentially saved by a healthier lifestyle among US adults.

MedicalResearch.com: What should clinicians and patients take away from your report?

Response: Two key taking home message:

(1)    Each heathy lifestyle was associated with around 2-3 years of prolonged life expectancy. The more the healthy lifestyle factors, the longer of the life expectancy.

(2)    For each health lifestyle factor, the healthier of each lifestyle, the longer life expectancy would be.

There is not too less or too much of the healthy lifestyle, everybody should find the level that most suitable for themselves. There will be a great pay back of prolonged life expectancy with each small step toward a heathier lifestyle.

MedicalResearch.com: What recommendations do you have for future research as a result of this study?

Response: Future research regarding how to be more healthier would be welcome, especially the practical strategies.

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.

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: 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

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.

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.

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: 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.

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.

Some Retirees Begin Risky Alcohol Consumption

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.

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.

Association Between Cardiovascular Risk Factors and Aortic Stenosis

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.

Lifestyle Modifications May Improve Health and Prognosis in Breast Cancer Patients

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: 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.

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.

Risk Factors For Adult Acne Identified

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.

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.
