Simple educational and motivational text messages can help people with diabetes manage their blood sugar better, a new study has found. It is not only an extremely affordable and scalable measure, but one that can be applied globally. According to the six-month Chinese study, diabetes patients who received the text messages and standard care reduced their glycated hemoglobin (HbA1c ) by more than patients who just received standard care. The results showed an average reduction in HbA1c of 2 mmol/mol (0.2%) in patients who received the supportive text messages. The group that did not receive the text messages experienced an average increase in HbA1c of 1 moll/mol (0.1%). For the study, the participants were split into two groups: one that received standard diabetes care and two text messages each month thanking them for their participation, and another group that received standard care and up to six text messages per week containing information on subjects like dietary advice, physical activity, emotional support and blood glucose monitoring. As well as actually reducing their HbA1c, the group receiving the supportive text messages also had a greater proportion of patients who achieved their HbA1C target of less than 7% (69.3% vs. 52.6% in the control group). Speaking about the findings of the study, Dr Xiqian Huo, of Beijing's Fuwai Hospital, said: “Lifestyle advice such as strict dietary control may have contributed to glycemic improvements, together with reminders to monitor blood glucose regularly. The messages were designed to provide information and motivation, and help patients set goals and manage stress.” The results of the study were presented at the annual meeting of the European Society of Cardiology on Saturday, August 31 also appear in journal Circulation: Cardiovascular Quality and Outcomes.
People with type-2 diabetes get no benefit from taking omega-3 fish oil supplements, a new study has found. According to researchers from the University of East Anglia, while omega-3 supplements are not harmful for people with type-2 diabetes (this has been a concern previously), they don’t provide any benefit either. This contradicts a common belief that omega-3 can protect against diabetes and even reverse the condition. The study, which involved 58,000 participants, found that people who consumed more omega-3 had the same risk of developing diabetes as individuals who did not. Furthermore, taking omega-3 fish oil did not influence levels of blood glucose, insulin and glycated haemoglobin - all measures of how the body handles sugar. ‘Better to eat fish’ Douglas Twenefour, deputy head of care at Diabetes UK, said: “Eating a healthy, varied diet is incredibly important, and we know that certain foods - including fruits, vegetables, wholegrains, yoghurt and cheese - can help to lower your risk of type 2 diabetes. “While omega-3 fatty acids are crucial for our overall health, it's generally better for people with type 2 diabetes to get their intake by eating at least two portions of oily fish a week, than by taking supplements." The advice from Dr Lee Hooper, who led the research, is to forego the expensive omega-3 supplements and instead buy oily fish and/or spend your money on physical activity, which will have more of a positive impact when it comes to type-2 diabetes.
While exercise has long been thought to help boost mental health and there’s evidence to support this, less is known about whether physical activity can actually prevent the onset of mental health conditions such as anxiety and depression. Indeed, previous studies have suggested that low levels of physical activity are associated with a greater incidence of several common mental health problems, but few studies have investigated whether the opposite is true: more exercise = less risk of developing mental health disorders – until now. By conducting a systematic review and meta-analysis of four different studies, the researchers from University College London were able to assess the impact of physical exercise on mental health risk. Publishing their findings in the Journal of Affective Disorders, the researchers said low and medium levels of cardiorespiratory fitness are associated with a 47% and 23% greater risk of common mental health disorders, compared with high levels of cardiorespiratory fitness. In other words, doing more physical exercise does seem to have a positive impact on a person's mental health risk. The research makes for interesting reading when you consider that mental health issues are growing and not everyone benefits from therapies and medication. The researchers are now planning to explore this avenue further to see if they can identify the underlying mechanisms of the relationship between exercise and mental health.
Even if you’ve been pretty physically inactive for much of your life, exercising more in your later years can still afford benefits and lower your risk of premature death, a new study has found. According to research by the University of Cambridge - which studied 15,000 Brits - by doing 150 minutes of moderate-intensity physical activity per week, physically inactive individuals can reduce their risk of early death by 24%. However, it’s people who are already physically active who can benefit the most from more exercise. That’s because the study found that individuals who were already doing 150 minutes of moderate-intensity physical activity per week could reduce their risk of early death by as much as 42%. Finally, all older adults involved in the study saw a “substantial” boost to their life expectancy by being more active – regardless of their activity levels previously. So, the simple message is clear: the more exercise, the better. And it’s never too late to make a difference in your life. Speaking about the findings of the study, the results of which are published in the British Medical Journal, Huw Edwards, from health body UKactive, said: “This provides further evidence against the outdated idea that people should do less as they age or while managing a long-term illness. “The time has come for a total rethink of how we approach our later years.”
We’ve only just written about how a low-carb diet may help relieve symptoms of knee osteoarthritis and now a new study has revealed that just one hour of brisk walking per week can significantly lower mobility-related disability in people with knee osteoarthritis. According to the research, the findings of which appear in the American Journal of Preventive Medicine, just one hour of weekly exercise lowered the risk of mobility-related disability in seniors with knee osteoarthritis by 85% and that of daily living disability by nearly 45%. For the study, a team of researchers from the Northwestern University Feinberg School of Medicine, in Chicago, IL, led by Dorothy Dunlop, Ph.D., analyzed data from more than 1,500 adults. All of the participants were living with osteoarthritis and experienced aches, pain, and stiffness in their lower extremities as a result. However, none of them had a disability prior to the study. Over a period of four years, the researchers monitored the participants’ levels of physical activity. They found that the seniors who got at least one hour of moderate-to-vigorous activity each week had no trouble performing a range of daily tasks. However, in seniors who did not engage in this much physical activity, 24% could not walk across a street before the traffic lights changed, and 23% struggled to perform their daily morning tasks. Speaking about the findings of the research, Prof. Dunlop said: “We hope this new public health finding will motivate an intermediate physical activity goal. One hour a week is a stepping stone for people who are currently inactive. People can start to work toward that.”
If you’re over 40, just 10 minutes of leisurely activity each week could lower your risk of death from multiple causes. That’s the key finding from a recently published study by researchers from China and the United States. According to the study involving 88,140 US adults, even low-level physical activity, such as gardening, can help people live longer lives. Publishing their findings in the British Journal of Sports Medicine, the researchers said that even people who spend just a short time each week being physically active have a lower risk of death due to cancer, cardiovascular issues and all-cause mortality. However, participating in more vigorous types of exercise, including running and cycling, affords even greater health benefits. Unlike people who were physically inactive, those who undertook between 10 and 59 minutes of moderate, leisurely exercise each week had an 18% lower risk of death from all causes. Those who were physically active for a little longer (between 150 and 299 minutes per week) had a 31% lower risk of all-cause death. Undertaking over 1,500 minutes of physical activity on a weekly basis resulted in a 46% decrease in overall mortality risk. Furthermore, individuals who opted for more vigorous exercise instead of lighter physical activity had a much lower mortality risk still.
Do you use a fitness tracker to monitor your levels of physical activity and keep an eye on how many calories you’re burning from day to day? If you do, you could be relying on overestimated information, according to the findings of a new study. Researchers at Aberystwyth University in Wales found that many popular fitness trackers often overestimate the number of calories burned while walking by over 50%. In fact, all products tested by the research team ranging between £20 and £80 in price were inaccurate during walking and running tests. Surprisingly, some fitness trackers gave polarising results. For example, the Fitbit Charge 2, the best-selling fitness tracker on the market, scored very well when it came to estimating calories burned while running, underestimating by just 4%. However, when measuring walking, the same device overestimated calories burnt by more than 50%. Other less expensive devices, namely the Letscom HR and the Letsfit – significantly underestimated the number of calories burned while running by 33% and 40% respectively. However, both were more accurate than the Fitbit Charge 2 in estimating calories burned while walking, overestimating by 15.7% and just 2% respectively. One of the researchers, Dr Rhys Thatcher, said that while fitness trackers can be great as motivational tools, people need to be cautious in the data they provide. “If you want to know the exact number of calories that you are burning during an exercise session then it doesn't matter which device you use, you have to interpret the data with some caution,” he said.
Strength training exercises benefit the heart more than aerobic activities, such as walking and cycling, new research suggests. The survey of more than 4,000 American adults found that static exercise, like lifting weights, is more effective at reducing the risk of heart disease than cardiovascular exercise. Specifically, while undertaking both static and dynamic exercise was associated with a 30% to 70% reduction of cardiovascular risk factors, the link was strongest for younger individuals who did static exercises. Nevertheless, any amount of exercise brings benefits and doing both static and dynamic types is still better than focussing on just one kind, the researchers from St. George's University in St. George's, Grenada said. Speaking about the findings of the research, Dr. Maia P. Smith, assistant professor at the Department of Public Health and Preventive Medicine at St. George's University, said: “Both strength training and aerobic activity appeared to be heart healthy, even in small amounts, at the population level.” Current American Heart Association (AHA) guidelines recommend that American adults should undertake at least 150 minutes of heart-pumping physical activity every week. The same guidelines also stipulate that said activity should be spread across the week and not completed in just one or two days. Are you doing enough physical activity each week? If not, you could be increasing your risk of cardiovascular disease. [Related reading: Why being overweight increases your risk of cancer]
Tablets, mobile phones and other handheld devices are extremely popular among children (and their parents). The former get visual stimulation, while the latter get some peace and quiet. But how does screen use affect a child’s cognitive ability? Well, according to a new study by researchers at Children's Hospital of Eastern Ontario Research Institute, less screen time results in better cognition. Specifically, children aged eight to 11 who used screens for fun for more than two hours every day performed more poorly in cognition tests than their counterparts who got less screen time. Moreover, the researchers found that less screen time, nine to 11 hours of sleep every night and at least one hour of physical activity led to even better results. Nevertheless, less than two hours screen time each day was the factor linked with the best performance results. Speaking about the findings of the study, Dr Jeremy Walsh, from the CHEO Research Institute, said: “Based on our findings, paediatricians, parents, educators, and policymakers should promote limiting recreational screen time and prioritising healthy sleep routines throughout childhood and adolescence.” The study, which looked at data from 4,500 children aged 8-11 from 20 locations across the U.S., is published in The Lancet Child & Adolescent Health journal.
What’s the fittest country in the world? Would you have any idea if you were asked? Even hazard a guess? Hint: It’s a country in Africa. According to a recent World Health Organisation (WHO) report, Uganda is the world’s most physically active country. Published in the medical journal The Lancet, the study findings are from a compilation of surveys completed in 168 countries. Just 5.5% of Ugandans do not do enough physical activity. People living in Lesotho, Mozambique, Tanzania and Togo are also getting plenty of exercise, too. In comparison, people living in Kuwait (the least active nation) have far more sedentary lifestyles, with 67% of the population not active enough. The report highlights a distinct divide between the levels of physical activity in poorer countries vs. wealthier countries. People in poorer nations are more likely to walk to work and/or have jobs that see them being physically active throughout the day. Recommended exercise guidelines for 19- to 64-year-olds Here’s what the UK’s NHS recommends: At least 150 minutes of moderate-intensity aerobic activity (such as cycling or brisk walking) or 75 minutes of vigorous-intensity aerobic activity (such as running or a game of tennis) every week Strength exercises that work all the major muscles at least two days per week Long periods of sitting should be broken up with light activity Are you getting enough physical activity? Could a small lifestyle change enable you to? [Related reading: Open-plan offices could improve health, reduce stress]
The sedentary lifestyles many office-based workers lead are often cited as having a negative impact on their health, but a new study suggests the type of office someone works in could make a difference. That’s because the US study of 231 employees found that those who worked in open-plan offices were more active and less stressed than their peers in cubicles or private offices. In fact, open-plan office workers clocked up 20% more physical activity than those in cubicles and 32% more than those who had their own office. But why? The researchers say it could be to do with open-plan office workers being more likely to get up and have a conversation with one of their colleagues if they can see them across the room, instead of using a telephone or email. The extra physical activity was thought to be a factor linked to the lower stress levels, suggesting that open-plan offices afford more than just physical health benefits. The University of Arizona study, published in Occupational & Environmental Medicine, is the first of its kind to actually monitor activity and stress levels using technology, instead of relying on individuals to fill out surveys. Esther Sternberg, a professor at University of Arizona College of Medicine and study author, said: “We all know we should be increasing our activity but no matter how we try to encourage people to engage in healthy behaviour, it doesn't work for long. “So changing office design to encourage healthy behaviour is a passive way of getting people to be more active.”
A large-scale study has found that just 45 minutes of physical exercise three to five times a week can improve mental wellbeing. [Related reading: People who abstain from alcohol in middle age may have higher risk of dementia] According to the US study of 1.2 million people, people who exercised regularly had fewer “bad days” a month than their non-exercising counterparts. Furthermore, while activities such as cycling, aerobics and team sports had the greatest positive impact, all types of physical activity, including things like doing household chores and looking after kids, were found to improve mental health. Moreover, people who had previously been diagnosed with a mental health condition like depression were found to afford the greatest benefits. The optimal routine identified by the researchers was being physically active for 30 to 60 minutes every second day. More interesting is the researchers’ finding that too much exercise can have a negative impact. Dr Adam Chekroud, study author and assistant professor of psychiatry at Yale University, said: "Previously, people have believed that the more exercise you do, the better your mental health, but our study suggests that this is not the case. "Doing exercise more than 23 times a month, or exercising for longer than 90-minute sessions is associated with worse mental health." The findings of the study are published in The Lancet Psychiatry Journal.
It’s natural for grandparents to dote on their grandchildren and give them sweet treats whenever they see them. But new research suggests this and other influences could have a negative impact on their grandchildren’s health. For the research, the team from the University of Glasgow analysed 56 different studies which included data from 18 countries, including the UK, US, China and Japan. They focused on the influence of grandparents who were significant in their grandchildren’s lives, but who weren’t necessarily primary caregivers. Three areas of influence were considered: diet and weight, physical activity and smoking. When it came to their grandchildren’s diet and weight, grandparents were found to have an adverse impact, with many studies highlighting how they feed their grandchildren high-sugar or high-fat foods - often in the guise of a treat. The researchers also found that grandchildren were perceived to get too little exercise while under the supervision of their grandparents. However, this did depend on whether the grandparents were physically active themselves or not. Furthermore, smoking around grandchildren became an area of conflict between parents and grandparents, with the latter often smoking while their grandchildren were present, even though they had been asked not to. Talking about the findings of the study, lead researcher Dr Stephanie Chambers said: "While the results of this review are clear that behaviour such as exposure to smoking and regularly treating children increases cancer risks as children grow into adulthood, it is also clear from the evidence that these risks are unintentional. "Given that many parents now rely on grandparents for care, the mixed messages about health that children might be getting is perhaps an important discussion that needs to be had."
We all know that regular exercise should be a part of our weekly routine, but finding the time and motivation is often difficult. But what if just a little bit of walking had the ability to considerably prolong your life? Would you make time then? A new study published in the American Journal of Preventive Medicine suggests that even as little as two hours of walking a week, compared with no physical activity at all, correlated with a lower risk of all-cause mortality. In other words, even levels of walking that do not meet government-issued guidelines still provide significant benefits and lower the risk of premature death by a considerable amount. Moreover, the study also found that going beyond government exercise guidelines was linked with a 20% decrease in mortality risk. Speaking about the findings of the study, Dr. Alpa V. Patel, Ph.D., strategic director of the Cancer Prevention Study-3 for the American Cancer Society (ACS), said: “Walking," she continued, "has been described as the 'perfect exercise' because it is simple, free, convenient, doesn't require any special equipment or training, and can be done at any age.” So, the next time you have a short journey to make and providing the weather is good and you’re feeling up to it, why not walk?
Depression affects around 6.7% of US adults every year. On a global level, the World Health Organization (WHO) estimates that more than 300 million people are currently living with the disorder. When it comes to treatment, medication, psychotherapy, cognitive behavioural therapy or a combination of these approaches is usually used. But new research adds weight to the argument for regular exercise as a depression treatment. Australia-based non-profit group Black Dog Institute conducted an analysis of data collected from 33,908 Norwegian adults who were followed over an 11-year period. Publishing their results in the American Journal of Psychiatry, the team, led by Prof. Samuel Harvey from the Black Dog Institute, found that not only does a little exercise bring substantial benefits, but a lack of exercise actually contributes to depression. Individuals who didn’t undertake any physical activity were found to be 44% more likely to develop depression than those who did just 1 or 2 hours per week. As a result, the authors concluded that approximately 12% of depression cases could have been prevented if the individual did at least 1 hour of exercise per week. "We've known for some time that exercise has a role to play in treating symptoms of depression, but this is the first time we have been able to quantify the preventive potential of physical activity in terms of reducing future levels of depression,” said Prof. Harvey.
While the association between a lack of exercise and an increased risk of chronic diseases, including type 2 diabetes and heart disease, is well-established, new research shows that just 14 days of physical inactivity can increase a person's risk such conditions. A study by the University of Liverpool found that young, healthy adults who switched from moderate-to-vigorous activity and then to near-sedentary behaviour for just 14 days experienced metabolic changes that could raise their risk of chronic disease and even premature death. Presenting their findings at the European Congress on Obesity 2017 in Portugal, Study leader Dr. Dan Cuthbertson and colleagues said that reducing physical activity for just 14 days led to a loss of skeletal muscle mass in the participants. However, the reduction of physical activity for 14 days also led to an increase in total body fat. Furthermore, said body fat was most likely to accumulate centrally, which the team notes is a significant risk factor for chronic disease. Current guidelines recommend that adults aged 18-64 undertake at least 150 minutes of moderate-intensity physical activity or 75 minutes of vigorous-intensity physical activity every week. However, the Centers for Disease Control and Prevention (CDC) says that fewer than 50% of adults meet these exercise recommendations. Are you doing enough exercise each week? Even just small lifestyle changes can make a big difference when it comes to your risk of chronic disease.
People with non-O blood could be at greater risk of stroke and heart attack, research suggests. Scientists say it's because A, B and AB blood contains higher levels of a blood-clotting protein. The research, which was presented at the 4th World Congress on Acute Heart Failure, analysed studies involving 1.3m people. It found that people 15 in 1,000 people with non-O blood suffered a heart attack, compared to 14 in 1,000 people with O blood. While these figures don't sound that startling at first, when applied to a whole population the numbers become more important. It is hoped that the findings will help doctors better identify who is at risk of developing heart disease. However, Dr Mike Knapton, associate medical director at the British Heart Foundation, said the findings would not have a large impact on the current advice issued by the charity. "Most of a person's risk estimation is determined by age, genetics (family history and ethnicity) and other modifiable risk factors including diet, weight, level of physical activity, smoking, blood pressure, cholesterol and diabetes. "People with a non-O blood group type - AO, BO and AB - need to take the same steps as anyone wanting to reduce their CVD risk." So regardless of your blood type, the advice remains the same: improve your diet, weight, level of physical activity and don't smoke. In addition, manage blood pressure, cholesterol and diabetes too. There's nothing you can do about your blood group, but you can make positive lifestyle changes to reduce your risk of heart attack and stroke.
More than 20 million people in Britain are physically inactive and increasing their risk of heart disease, according to a new report by the British Heart Foundation. The charity has warned that the lack of exercise by such a large proportion of the British population is costing the NHS a staggering £1.2bn each year. Women are 36% more likely than men to be physically inactive, which the report defines as not meeting the UK government's guidelines for physical activity - 150 minutes of moderate to vigorous intensity physical activity and strength exercises on two or more days a week. However, despite the report finding that 11.8 million women were physically inactive compared with 8.3 million men, it is actually men who sit down for longer (78 days a year compared to 74 for women). Furthermore, inactivity levels differ by region. For example, 47% (2.7 million) of people living in the North West of England were found to be inactive, whereas people in the South East had the lowest rate at 34%. Over five million deaths across the world each year are attributed to physical inactivity, making it one of the top 10 leading causes of death. In the UK, physical inactivity contributes to almost one in 10 premature deaths from coronary heart disease each year, as well as one in six deaths from any cause. Dr Mike Knapton, associate medical director at the British Heart Foundation, said: "Levels of physical inactivity and sedentary behaviour in the UK remain stubbornly high, and, combined, these two risk factors present a substantial threat to our cardiovascular health and risk of early death.
Despite the fact the number of people who are overweight or obese has risen over the past 30 years, fewer people are actually attempting to shed weight, according to a new study, the findings of which were published in JAMA. Around two thirds of the adult population in the United States are obese or overweight, putting them at increased risk of heart disease, stroke, diabetes, and other chronic diseases. However, new research has found that even though there has been a significant rise in the number of people who are overweight or obese since the 1980s, the percentage of U.S. adults who are trying to lose weight has fallen. For their research, study co-author Dr. Jian Zhang and her colleagues from the Georgia Southern University, analysed the data of 27,350 U.S. adults aged between 20 and 59 years. The analyses revealed that the rates of overweight and obesity increased by 13%, from 53% in 1988-1994 to 66% in 2009-2014. Furthermore, the researchers also found that the percentage of people who attempted to lose weight over the same period actually dropped by 7%, from 56% in 1988-1994 to 49% in 2009-2014. At present, people are deemed to be overweight or obese depending on their body mass index (BMI). A BMI of 25 to under 30 is considered overweight, while a BMI of 30 or above is considered obese. A healthy diet and regular physical activity are proven to help curb weight gain, which is why we should all make a conscientious effort to watch what we eat and exercise more.

People who cram all their recommended weekly exercise into one or two sessions at the weekend can realise important health benefits, a study suggests. Furthermore, just being active, without undertaking the recommended 150 minutes of moderate activity every week, is still enough to reduce the risk of premature death by a third. Researchers from Loughborough University and the University of Sydney analysed the survey responses of around 64,000 adults aged over 40 in England and Scotland focusing on the amount of time they spent doing exercise and their general health over an 18-year period. They found that no matter how many times people exercised in a week, as long as they met the recommended guidelines the health benefits were the same. The findings of the study are particularly good news for people with busy lives who simply do not have enough time during the week to exercise. These particular individuals often squeeze all of their physical activity into the weekends, leading to them becoming known as "weekend warriors". In fact, these so-called "weekend warriors" were found to lower their risk of dying from cardiovascular disease by 41% and cancer by 18%, compared with people who were inactive. Commenting on the findings of the study, Justin Varney, national lead for adult health and wellbeing at Public Health England (PHE), said: "The maximum health benefits are achieved from 150 minutes of moderate activity per week. "However, every little counts and just 10 minutes of physical activity will provide health benefits."
The New Year is here and for many of you that will mean a new exercise regime designed to get you into shape and improve your overall health. For some people, though, sticking to a disciplined program of physical exercise is one of the hardest resolutions they can make because a lack of motivation gets in the way. But now new research sheds some light on why many people, despite understanding the benefits of regular exercise, find it hard in practice to stay physically active. Researchers from the Diabetes, Endocrinology, and Obesity Branch at the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), led by Alexxai V. Kravitz, focused on why obese animals also have a hard time carrying out physical activity. They found that a dysfunction in obese rodents' dopamine systems might help explain why. Mice fed on a high-fat diet started gaining significantly more weight than mice fed on a normal diet. They were also observed to have fewer movements; spend less time moving; and were slower when they did move, compared with the lean mice. Most interesting of all was that the overweight mice's changes in movements did not correlate with body weight gain. Instead, the researchers found that a deficit in striatal D2R explained the obese mice's lack of activity. "In many cases, willpower is invoked as a way to modify behavior. But if we don't understand the underlying physical basis for that behavior, it is difficult to say that willpower alone can solve it," said Kravitz.
Researchers have found that laughter may really be the best medicine when it comes to a person's health in later life. And, according to the study led by Georgia State University, when laughter is combined with moderate exercise, not only is the mental health of older individuals improved, but also their motivation to undertake physical activity. Prior to their research, lead author Celeste Greene, from Georgia State, and colleagues noted that many seniors are reluctant to carry out physical activity because they lack motivation due mainly to the fact they don't find exercise enjoyable. That's why Greene's team set out to investigate whether combining laughter with physical activity would increase the amount of enjoyment older people get while exercising, thus increasing the likelihood of them doing more and reaping the associated health benefits. For older people, regular physical activity can improve heart health; reduce the risk of diabetes; aid weight control; improve bone health; and maintain and boost muscle strength. Greene and her team created LaughActive, a unique laughter-based exercise programme, which combines moderate-intensity physical activity with simulated laughter techniques. The research team enrolled 27 older adults in the LaughActive programme, who were all required to attend two 45-minute sessions every week for a period of 6 weeks. What they found at the end of the 6-week programme was that 96.2% of participants said that laughter was an enjoyable addition to physical activity and boosted their motivation to take part. In addition, the programme was associated with significant improvements in the mental health and aerobic endurance of the participants.
One hour of "brisk exercise" each day can offset the risk of early death for people who are desk-bound in their working lives, according to scientists. The study of physical activity - the results of which were published in The Lancet - analysed data from more than one million people to see how being inactive affects people's health. Watching TV was found to be worse than sitting at a desk. This is because of the associated habits that go with it, like snacking. However, even people who sit at a desk for eight hours a day because of their jobs can compensate by undertaking an hour of physical activity. In fact, the research found that desk-bound workers who were physically active had a significantly lower risk of death than people who weren't physically active and only sat for a few hours. At present, NHS guidelines recommend people do at least 150 minutes of exercise per week. The new research suggests that is insufficient for many. Being inactive has long been linked to conditions such as heart disease, diabetes and some cancers, and accounts for around 5.3 million deaths globally each year. For comparison, smoking accounts for around 5.1 million. Prof Ulf Ekelund, Lead author of the study, from the Norwegian School of Sports Sciences and Cambridge University, said that people don't even need to do sport or go the gym to exercise. "It’s OK doing some brisk walking, maybe in the morning, during lunchtime, after dinner in the evening. You can split it up over the day, but you need to do at least one hour," he said.
From 1999 to 2014, rates of severe obesity among kids in the US climbed, highlighting that the issue still very much continues to plague American children today. Examining national data over the 15-year period, researchers found that a third of children in the US aged between two and 19 were overweight. They also found, more worryingly, that nearly a quarter were obese and two per cent severely obese. Lead researcher Asheley Skinner, from the Duke Clinical Research Institute in Durham, N.C., said: "Despite other recent reports, all categories of obesity have increased from 1999 to 2014, and there is no evidence of a decline in the last few years." Skinner added that there are currently 4.5 million obese kids in the US who urgently need treatment because they have a heightened risk of developing type 2 diabetes, heart disease and cancer, compared with children their age who are not obese. "Unless we make big changes on a national level, we're not going to see huge changes in obesity," Skinner said. By changing school lunches; increasing opportunities for physical activity, and allowing parents access to more healthy food options, the problem of childhood obesity can be tackled head-on, according to Skinner. The study, the results of which were published in the journal Obesity, also found that rates of obesity were higher in black and hispanic children, suggesting these groups need particular help going forward to combat the problem.
The benefits of exercising regularly are well-known and abundant, but now new research suggests that it may also help relieve symptoms of asthma in adults. The study, which was published in MJ Open Respiratory Research, focused on the physical activity levels of 643 adults diagnosed as having asthma. It found that those who exercised the recommended amount each day (30 minutes) were almost 2.5 times more likely to have their asthma symptoms under good control, compared to those who did zero exercise. Furthermore, the exercise does not necessarily need to be strenuous, according to lead author Simon Bacon, a professor in the Department of Exercise Science at Concordia University in Montreal, Canada. "Just 30 minutes a day of walking, riding a bike, doing yoga - anything active, really - can result in significant reduction of asthma symptoms,” he said. Asthma cannot be cured, but its symptoms can be controlled and the individual can enjoy a good quality of life if it is effectively managed and it seems exercise is now a key factor for that management. World Health Organisation (WHO) figures show that there are around 235 million people in the world who have asthma. Conventional advice was that asthma sufferers should try and avoid exercise as it can trigger attacks. But Professor Bacon says this can be avoided if the right measures are taken: "The issue of exercise-induced bronchospasm is real - but if you use your reliever medication, blue puffer, before you exercise, and then take the time to cool down afterwards, you should be okay. Even if you have asthma, there's no good reason not to get out there and exercise,” he said.
Just last week we told you about how a simple saliva test could be used to predict a person’s risk of Alzheimer’s disease. And now this year’s Alzheimer's Association International Conference (AAIC) in Washington, D.C., has heard how physical exercise not only has the potential to reduce the risk of Alzheimer’s, but also effectively treat it as well. Maria Carrillo, chief science officer of the Alzheimer's Association, said: “Based on the results we heard reported today at AAIC 2015, exercise or regular physical activity might play a role in both protecting your brain from Alzheimer's disease and other dementias, and also living better with the disease if you have it.” The randomised controlled trials sought to assess whether moderate to high-intensity activity had an effect on 200 patients with mild to moderate Alzheimer’s symptoms. The team from the Danish Dementia Research Centre in Copenhagen, Denmark, led by Dr. Steen Hasselbalch, found that the group of patients following the exercise programme experienced significantly fewer of the neuropsychiatric symptoms often associated with Alzheimer’s disease. "While our results need to be verified in larger and more diverse groups, the positive effects of exercise on these symptoms that we saw in our study may prove to be an effective complement or combination with antidementia drugs," said Dr. Hasselbach. "This calls for further study of multimodal treatment strategies, including lifestyle and drug therapies." The study further highlights the importance of undertaking physical exercise on a regular basis. The list of proven health benefits is increasing all the time and just a little physical activity now could dramatically improve your life in the future. Photo credit: Medical News Today
A study of 5,700 men in Norway has revealed that doing just three hours of exercise per week has a dramatic effect on life expectancy, with regular exercisers living up to five years longer than their sedentary peers. The study’s authors, writing in the British Journal of Sports Medicine, have called for more campaigns to encourage regular exercise and fitness in older people. Conducted by Oslo University Hospital, the study found that both light and vigorous exercise had a positive impact on life expectancy. This tallies with official UK government advice, which recommends 150-minutes of moderate exercise per week for people aged over 65. While the study showed that doing less than an hour a week of light exercise had little impact, those undertaking the equivalent of six 30-minute sessions – regardless of intensity – were a whopping 40% less likely to have died during the study, which lasted 11 years. "Even when men were 73 years of age on average at start of follow-up, active persons had five years longer expected lifetime than the sedentary,” said the report. It even added that exercise was as "beneficial as smoking cessation" at reducing deaths. Julie Ward, from the British Heart Foundation, reiterated the study’s findings, saying: "Regular physical activity, whatever your age, is beneficial for your heart health and ultimately can help you live longer.” Photo credit: Human Kinetics Sport, Health & Fitness Blog
A new study has found that just two minutes of walking could counter the negative effects of prolonged sitting. In the past, numerous studies have suggested that sitting for prolonged periods of time could increase an individual’s risk of heart disease and early death. This is thought to be because a staggering 80 percent of Americans are unable to carry out two and a half hours of physical activity every week – the recommended amount. This led a team from the University of Utah School of Medicine to conduct a study to discover whether more realistic, low intensity activities resulted in positive health effects. The study’s findings, which were published in the Clinical Journal of the American Society of Nephrology (CJASN), showed that two minutes of light intensity workout every hour resulted in a 33 percent lower risk of death. The lead author of the study, Srinivasan Beddhu, M.D., said: "It was fascinating to see the results because the current national focus is on moderate or vigorous activity.” He added: “To see that light activity had an association with lower mortality is intriguing." Regular exercise is still highly recommended for people who can perform it, but the two minutes of walking every hour advice is a step in the right direction for those who can’t.

It won’t come as any surprise that Americans gain weight as they get older. However, you may raise an eyebrow to learn that as Americans age and pile on the pounds, the quality of their diet actually gets better. Therefore, we can safely say that as their waists expand and they realise something needs to be done, Americans try and counteract their weight gain by eating salads and lean proteins. But, according to a new study by the University of South Carolina, improving one’s diet simply isn’t enough to stave off weight gain in our later years. Using data collected from 4,999 Americans aged between 20 and 70, the study painted a complete picture of how the individual’s diet and exercise levels alter over the years. Lead researcher Russell Pate Ph.D. said: "Our study points to the very important impact of physical activity on weight status in U.S. adults, and in particular it points to the critical role of the age-related decline in physical activity on the increasing rates of overweight and obesity that we see with aging.” The bottom line? Americans should absolutely be trying to achieve the 150-minutes of moderate exercise as per the federal physical activity guideline. According to the American Heart Association, the activity levels of Americans are generally lower nowadays because of more sedentary jobs, better mass transport options and technology. Being overweight increases the risk of diabetes, cardiovascular disease, reproductive problems and some cancers.
Weight loss has long been advised for women who are struggling to conceive, but now new research shows that obese men who lose weight are more likely to get their partners pregnant. The research – which was recently presented at the annual meeting of the Endocrine Society – was conducted by a team from the University of Sherbrooke in Canada. It is thought to be the first study of its kind and experts say that it represents an interesting alternative to IVF and opened up “real possibilities” for men. The study focussed on 65 couples who had been referred to a fertility clinic. For one year, the men attended weekly group sessions about nutrition and physical activity. It was then discovered that the men who had lost the most weight were the ones who conceived. "This is the first prospective study suggesting that male partners who improve their weight also increase the odds for the couple to conceive,” said Dr Jean-Patrice Baillargeon. He believes that obesity not only affects a man’s sperm count, but also the quality of his sperm. The findings of the study mean that going forward the advice for both men and women who are trying for a baby could be to lose weight in the first instance.
