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

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.

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.
