Why making just two lifestyle changes can have positive and far reaching affects on health

A recent study, at the Northwestern University Feinberg School of Medicine, found that changing one bad habit can have a positive knock on effect on other behaviours.  A simple step such as watching less television, can simultaneously reduce the amount of time one spends snacking on unhealthy foods – as these two behaviours are closely related.   As such, the notion that you must radically transform your life in order to be healthier is not necessarily true and often hard to maintain.  Making just a couple of small changes, as the study demonstrates, can have a real and long lasting impact on people’s health.

The study was conducted by Bonnie Spring, professor of preventive medicine at Northwestern University Feinberg School of Medicine, in an attempt to find out the most effective way to spur people to change common bad health habits.  204 adult patients with unhealthy habits, were given the following treatments; an increase in vegetables/fruit and physical activity and decrease in fat and sedentary leisure.  Over the course of the three weeks, the patients had to record their daily data into a personal digital assistant in order to establish if they met their goals. 

After the three weeks, patients no longer had to maintain their “healthier” lifestyles, but were still required to send data three days a month for six months.

After the completion of the six months, the study found that the patients kept to their new healthier lifestyle changes rather than reverting back to their old habits.  Around 86% of the participants said that once they had made the initial change, they tried to maintain it.  By incorporating fruits and vegetables in their diet empowered them to believe that they were in fact capable of change. 

The results indicated that the most effective way to improve health required two key behaviour changes, namely cutting the amount of time spent watching TV or on the computer and eating more fruits and vegetables.  It is believed that these two simple changes could have long lasting results.   

Spring said, "Just making two lifestyle changes has a big overall effect and people don't get overwhelmed."

The majority of the population, where obesity is most prevalent, often lead unhealthy and sedentary lifestyles, putting them at high risk for heart disease, diabetes and cancer.  Spring argues that it is often hard for doctors to know where to initiate change in unhealthy habits, without discouraging or offending patients.   Thus this “two way” simple approach enables others to make realistic and manageable changes by giving them confidence to carry it out.

“With this simplified strategy, people are capable of making big lifestyle changes in a short period of time and maintaining them”

Saving Lives Through Changing Behaviour

Fresh food, more exercise and no smoking.  These are some of the choices we need to make in order to lead a healthy lifestyle, which is sustainable in the long term.

The Royal Society for Public Health (RSPH) http://www.rsph.org.uk/ has responded to the Government’s White Paper, by developing a suite of training programmes on Behaviour Change designed specifically to support health and well being professionals to deliver these messages effectively as part of their behaviour change strategy. 

Professor Richard Parish, Chief Executive of RSPH comments:

“It is our belief that spreading skills and knowledge in this area will have a direct effect on driving behaviour change and reducing health inequalities, resulting in healthier communities across the country.”

Rises in obesity, diabetes, heart disease and sexually transmitted infections (STIs), alongside problems associated with unhealthy eating, drinking and smoking habits, have placed our health service under huge pressure.  As many health conditions are both preventable and avoidable, we have a responsibility to ensure that we intervene and steer people towards healthier lifestyle choices.  This not only positively impacts the wellbeing of the individual but also their communities.

Preventing avoidable conditions is better for both the patient and the health service, but the approach differs depending on the time available, the skill of the individual and the nature of the contact.

The programmes are tailored to help everyone and range from a short introduction for frontline staff right through to strategic planning for leaders and managers.

Influencing Behaviour Change

An introduction to communication and sign-posting

This one day workshop for front-line staff explores the potential improvements they could make to community health by influencing changes to behaviour. Drawing on motivational interviewing techniques and a variety of communication styles, participants will gain a clear understanding of how they can increase the impact of everyday contact with their community.

Making Every Contact Count

An introduction to the Behaviour Change competence framework

This half day programme introduces participants to the competence framework which has been developed by NHS Yorkshire and The Humber. It is designed for use at all levels of experience and provides a common approach against which skills can be assessed, either within a single programme or for an entire workforce. This will enable individuals to identify gaps in their knowledge, Commissioners to address weaknesses in their provision, and Service Providers to offer exactly what is needed.

Cutting out the Fat....

The relationship between fatty foods and developing type 2 diabetes

As levels of obesity continue to rise, posing as a serious threat to public health, conditions of type 2 diabetes has also increased.  Evidence has suggested a strong link between obesity and developing type 2 diabetes, however, scientists have now discovered how a high fat diet can cause type 2 diabetes.  Researchers believe this discovery will not only help explain the relationship between fatty foods and obesity, but it may lead to finding a cure for the disease.   

This week the Daily Mail and BBC Health News reported the findings.

The study published in the peer-reviewed journal Nature Medicine, was carried out by researchers from the University of California and the RIKEN Advanced Science Institute in Japan.  The study sought to investigate whether a high-fat diet might contribute to causing type 2 diabetes, by looking at its effect on the insulin producing cells of the pancreas on mice, and on the response of cells to insulin.  The scientists investigated their findings further on human pancreatic cells in the laboratory.

The Science bit

In type 2 diabetes, the cells in the pancreas that normally produce insulin – called beta cells – gradually stop working over time.  These cells respond to increased levels of sugar in the blood by producing insulin, but this ability is lost in type 2 diabetes.  The cells of the body become less responsive to insulin (insulin resistance) and fail to take up the sugar in the blood stream.  This then causes high levels of sugar circulating around the body, which is detrimental to cells and tissues.   

The Research

Scientists looked at what effect a high-fat diet had on the activity of certain genes and proteins in the cells that are thought to help the beta cells function. Particular focus was placed on a protein called GnT-4a glycosyltransferase.  In healthy pancreatic cells this protein helps in the detection and response to glucose in the blood stream.

The researchers found that when they fed mice a high-fat diet, the genes encoding the GnT-4a protein and one of the glucose sensing proteins (called Slc2a2) became less active in the mice’s pancreatic cells.

The scientists also genetically engineered mice to have a form of GnT-4a that was always active in the beta cells. They then looked at how these mice responded to the high-fat diet.  The theory was that if dietary fat had its effects by stopping these proteins working, then these genetically engineered mice should be less susceptible to the effects of a high-fat diet.

The Findings

It was found that high-fat diets in mice affected the insulin-producing cells, reducing their ability to correctly respond to the presence of glucose.  As such, there were high levels of glucose circulating in the bloodstream and a reduced ability of certain tissues to respond to insulin and take up sugar.   Tests on pancreatic tissue from people with type 2 diabetes suggested that similar changes may be occurring in humans.

However, in mice genetically engineered to have GnT-4a work constantly in the beta cells, the high-fat diet had less of an effect on blood sugar levels and the ability of the cells to respond to insulin, even though the mice became fat.  This enhanced understanding of the effects of fat on pancreatic cells, provides a possible biological explanation as to why high fat diets can lead to type 2 diabetes. Researchers believe this will also aid the development of possible new treatments for type 2 diabetes.

However, human research is a lengthy process and finding a cure for type 2 diabetes may take years.  Thus, the best current advice to prevent type 2 diabetes, is to maintain a healthy weight, do exercise and eat a healthy diet.  For further information on this research please visit NHS Choices

Getting Sporty – The Benefits for Body and Brain!

It is widely accepted that exercise has many beneficial effects on the body.  However, a new review article entitled “Exercise, Brain and Cognition Across the Lifespan” published in the Journal of Applied Physiology, highlights that the positive effects of exercise also extends to the brain, influencing cognition.  The article draws upon recent evidence which identifies physical activity as positively affecting the body and also the mind.     

Michelle W. Voss, from the University of Illinois at Urbana-Champaign and her colleagues affirmed that both aerobic exercise and strength training play an essential role in maintaining brain and cognitive health throughout life.  However, they also highlighted that this area of research still needed to be explored into understanding how certain aspects of exercise influence brain physiology and function.   

The Results

The article used the findings from 111 studies to demonstrate the effects of aerobic exercise and strength training on humans from children through to the elderly. 
It was found that aerobic exercise was crucial for getting a head start during childhood on cognitive abilities.  It suggested that physical inactivity was associated with poor academic performance, whereas, exercise programs could help to improve memory, attention and decision making.  These effects, it was argued, extend to both young and elderly adults. 

There was strong evidence that showed aerobic training benefitted executive functions, including multi-tasking, planning and inhibition, as well as improving memory.  This is particularly evident for high-intensity and high load training for older adults.  More research needs to be carried out on the effects of strength training on brain health for children. 

Animal studies, which examine the influence of aerobic exercise has found that physical activity appears to change the brain structure, promoting the growth of new nerve cells and blood vessels.  It is also recognised as increasing the production of neurochemicals, such as BDNF and IGF-1 which help to promote growth, survival and repair of brain cells. 

Clearly, the studies identify the positive effects of exercise on the brain, but the article also made clear that there were gaps in the scientific literature and more needed to be done to examine how exercise type might promote different effects on brain health and cognition at different ages. 

"It is increasingly prevalent in the print media, television, and the Internet to be bombarded with advertisements for products and programs to enhance mental and physical health in a relatively painless fashion through miracle elixirs, computer-based training, or gaming programs, or brief exercise programs," the authors say. "Although there is little convincing scientific evidence for such claims, there have been some promising developments in the scientific literature with regard to physical activity and exercise effects on cognitive and brain health."

RSPH – Sport for Health

Sir Liam Donaldson, Chief Medical Officer stated that:

“The potential benefits of physical activity to health are huge.  If a medication existed which had a similar effect, it would be regarded as a ‘wonder drug’ or ‘miracle cure’.

RSPH Training Solutions, recognises the importance of how sport can play a vital role in improving ones overall health and wellbeing.  However, the problem stems in that so many people avoid sport and thus ignore one of the cheapest and most effective ways to improve health.  Sport for Health is a programme which has been designed for people who work in sport, either in a professional or voluntary role.  It aims to help them increase the level of physical activity amongst people by understanding how an active lifestyle promotes good health and also understanding the barriers people face and ways to overcome them.

Through the Mayor’s Legacy Fund, applicants can apply for funding which entitles them to 75% off the cost of the course.  For more information on Sport for Health please click here or email sportforhealth@rsph.org.uk

New Years Resolution - Do More Exercise.....

Exercise keeps the brain from ageing

Research from the University of Florence and other institutions in Italy carried out a study which found that low to moderate exercise can prevent the milder forms of cognitive decline in older age.  The research was published in the Journal of Internal Medicine.

The research pooled the results of fifth teen studies and included the analysis of 33,816 people without dementia, who were followed between one and twelve years.  It revealed that exercise consisting of playing a round of golf once a week or tennis twice a week, was linked to a 35 percent reduction in the risk of cognitive decline.  The researchers believed that physical activity which raises your heartbeat, increases the blood flow to the brain and helps to reduce the mind deteriorating in later years.

The researchers explained that it has been widely acknowledged that physical activity has positive effects on a wide range of health measures, including reducing the risk of heart disease and stroke, diabetes, obesity, hypertension and some cancers.  However, the study demonstrated that attention, memory and concentration (known as cognitive functions) which typically deteriorate with age, can also reap the benefits by maintaining a healthy lifestyle and partaking in regular exercise. 

The analysis of the studies showed that subjects who performed a high level of physical activity were significantly more protected (by 38%) against cognitive decline during the follow up, compared to people who reported being sedentary. 

We all have a responsibility to look after our health and well-being and what a better time than now to include exercise and healthy eating as part of your new years resolutions. 

The Royal Society for Public health through Training Solutions run a Foundation Programme in Health Improvement.  The course offers candidates the opportunity of developing a firm foundation in Health improvement while also making aware the health and lifestyle choices that affect personal and public health.  For more information click here or contact Nicolette Smith.
