In public health, we aim to give people the necessary information and tools to help them make the right choices so they, and their families, can live healthier lives for longer.
The fact is, although people in the UK are living longer, their quality of life is often poor, with too many living with ill health and disability due to illness that could have been prevented. Obesity continues to be one of the leading causes of heart disease and early death, yet 62% of adults in England are overweight, and the picture looks no better for our children with one in ten already classed as obese.
So how can public health professionals influence population behaviours that are seemingly inherent in society, such as frequently eating at fast food outlets and drinking alcohol throughout the week? At Public Health England, we use behavioral insights to help shape our public campaigns to encourage people to lead healthier lives, including stopping smoking, eating healthier and exercising regularly.
The New Year brings renewed motivation for personal change and an opportunity to reassess and reengage with our health. Of course most people don’t structure their lives around the latest health campaign – and human nature dictates that we might decide to alter our lifestyle at any point. However, evidence shows that rallying together for a fresh start on a specific date can lead to successful behaviour change, and this is something we try to incorporate into many of our public health initiatives.
The ‘fresh start’ moment
We are all too familiar with New Year’s resolutions to stop smoking, drink less alcohol, or exercise more. Unsurprisingly, Google search terms such as ‘diet’ and ‘gym visit’ increase significantly in the New Year period.
Part of the appeal of these resolutions is what is known as the fresh-start effect; a moment in time where we feel closer to our future, healthier self and more distant from our past unhealthy behaviour.
The Dry January campaign takes advantage of the fresh-start effect. It supports people to go without alcohol for a month as a means of encouraging them to reassess their relationship with alcohol. And the fact that many people will have been drinking more than usual throughout the festive period should make their decision to sign up to the challenge that bit easier.
However, we need to be careful about making resolutions at times when we lack the ability to accurately predict our future behaviour, such as deciding to quit eating chocolate just after a hearty and indulgent Christmas dinner. This type of decision leads to a higher chance of abandoning our resolution, as we fail to appreciate how we will feel in the New Year when we’re back at work and hungry for a sweet treat. Support and tools to help people stick to their resolution are essential.
For example, the Booze Buster is a free tool that emails you with tips and support to help you choose less booze. An online Drinks Checker and Drinks Tracker app are also available to make it easier to keep tabs on how much you are drinking.
The social context and physical environment: applying behavioural insights
Healthy behaviours are a result of the decisions an individual makes on a daily basis, but we know that many of these decisions are automatic, and a person’s environment – both social and physical – can make it easier or harder to make healthy choices. For example, smokers often socialise with other smokers, with research showing that a person is 61% more likely to smoke if their partner or a close friend smokes.
However, this premise can work positively too. For example, smokers are two thirds more likely to quit when their spouse stops smoking. A third are more likely to quit when a close friend or someone they work with stops. Quitting together forms an integral component of our Stoptober campaign, which encourages people to sign up with their friends, family and colleagues. The physical environment also plays a crucial role in smoking behaviour: an essential step for someone aiming to quit is to remove smoking ‘cues’ such as ashtrays and lighters.
So, to achieve better health, we must make sure our environment supports our new behaviours; place your gym shoes in sight and put junk food out of reach. Social support is also consistently shown to increase success of weight loss goals and group weight loss interventions are generally more effective.
It doesn’t have to be ‘all or nothing’
In addition, incremental changes are useful as a way to improve healthy behaviours over a period of time. Referred to as ‘chunking’, dividing complex or large goals into manageable sub-goals increases the probability of successful behaviour change. For example, the NHS Couch to 5K running plan, which can be downloaded as a handy app, is a great example of breaking a large goal into small manageable chunks.
Healthy change is not necessarily an ‘all or nothing’ solution; tangible, small steps can be incredibly effective. Change4Life’s Smart Restart and Do One Thing tools, for example, can be used to encourage small step changes such as swapping high sugar lunchbox items for healthier alternatives or walking for 30 minutes per day.
Our Change4Life ‘10-minute shake-up’ initiative also helps children to reach the recommended 60 minutes of physical activity a day, breaking it up and providing a range of 10-minute activities for them to do throughout the day. Last year’s campaign saw an extra 40,000 kids reach the recommended hour a day.
As public health practitioners, we recognise the importance of the social and physical environment in making healthy choices. By utilising behavioural insights to develop public health interventions we can support individuals to make positive changes to their behaviour. We need to nudge people into change, influence behaviour and make healthier options easier for people to make so that they become the social norm.
Stoptober is a great example of a campaign that takes these behavioural insights into account, offering people the chance to get together with friends to stop smoking and starting on a specific date.
It also uses the concept of ‘chunking’, challenging people to stop smoking for the month of October, rather than aiming to quit for good. Yet those that reach the 28 day-goal are five times more likely to remain smoke free.
It is clear that achieving healthy behaviours across the population is a complex challenge. But there are a number of methods that public health professionals can use to help people make healthy changes.
The biggest challenge to a new resolution is the brilliantly named ‘what-the-hell’ effect. Generally we set rules to help us to meet our goals: "I will eat a banana for my afternoon snack rather than a chocolate bar". If we break these rules we become vulnerable to the ‘what-the-hell’ effect.
Once the rule is broken, we overindulge, abandon our resolution and slip back into our previous unhealthy behaviours. It is likely that we will break our rules at some point, but to get over this hurdle it is vital that we understand how to manage these situations. For example, the Change4Life Fruit & Veg Boost is a great tool for those trying to eat more healthily, sending hints and tips via email every Friday and a free recipe to help you stick with your chosen plan.
New Year is a great opportunity to think about health and plan for the year ahead, but behaviour change is not limited to this one moment in time. The ‘fresh-start effect’ can be channelled at the beginning of a new week, the start of a new month, following a birthday or even after a holiday.
If you are planning a public campaign in 2016, behavioural insights can be a really useful tool. If you’re setting your own resolution, make sure your goals are achievable and sustainable. And for an even greater chance of success, why not get a family member or friend on board too?

Some good advice.
But for all but the biggest lifestyle changes I wonder if the additional stress of living a lifestyle other than your preferred one and having to constantly trick yourself into staying on that path cancels out any marginal physiological benefits from relatively small lifestyle changes. Sometimes I think we would all be a lot healthier - and certainly a lot happier - if we stopped obsessing about the ever-changing understanding of the marginal impacts on our health of everyday life and just got on with enjoying life. After all, you could be run over by the pro0verbial bus tomorrow whilst jogging to the gym.

Richard. I agree. I am trying to change my life style gradually. By changing everything all at once, not only are you more likely to fail, then 'Pig' out on lard, but you get stressed out trying to comply exactly with what your doctor/consultant says. One further point. I am more likely to become healthier if I decide to do it rather than my doctor/consultant being 'pointy fingered' at me!!

In my view the growth of Parkruns has got to be one of the most spectacular initiatives for improving public health. It is astonishing to see just how many people now turn out to run or walk 5km in their local park on a regular basis at these free to enter events. The diversity of the participants is particularly encouraging and hopefully they will keep the good habit of regular exercise for life.
And crucially for me Parkrun is a genuine example of "Big Society" - not a system imposed from above at great expense but rather people doing things for themselves, and volunteering on the weeks when they don't run.

Jogging is bad for you. It prematurely wears out the joints. Have you joggers already 'booked in' for your hip and knee replacement operations in 20 to 30 years' time? Do you realize what damage you are doing to your back by the continual repetitive percussive pressure on your spine? When you are young you don't realize that the body wears out. I suggest that you take up walking and swimming instead.
Also there is an immediate cure for obesity - stop eating! By treating obesity as a medical condition we are merely being over indulgent to those who already have over indulgent eating habits.

Any possibility we'll have a calendar with an "unnamed" month in it? "Dry January", "Stoptober", "Movember" just three that I can name off the top of my head. I wouldn't be in the least surprised to find that this is the result of some focus group or organsiation set-up purely to come up with all these "Fun and Wacky Ideas". Do we really need all these "Mass Participation Gimmicks" in our lives? What next, all lining up first thing in the morning to sing the Comapny song?

As with everything, it is the little changes that we can remain constant with that impact the most overall. For example, walking to work instead of driving (I live one mile away), or walking to the shops if you don't have to carry too much. The well known organisation Weight Watchers now realise that we should be looking at our health 'holistically', so not just the food or alcohol we consume, or the exercise we do, but how we feel about ourselves and how good our own mental health is. Wouldn't it be great if the department were able to organise meetings on site so that we could all support each other, as per the 'social context' mentioned about?

Ok, lets realise that attempting to aspire to brand new YEARLY aspirations of fitness, healthy eating and alcohol reduction or abstinence, is not going to happen long term, unless, we realise, that to maintain these aspirations, for them to be life changing, it has to be a life long change, therefore, goals need to be realistic, to be achievable, not a daily chore, but besides, a little pressure, .pleasurable too.
Instead of immediately signing up for The New York or London Marathon, or heaven forbid, both, or seizing, the nearest carrot stick/ chomping lettuce leaves, as if you were a rabbit, in a previous life, just CHILL, stop for a moment, and re organise your life plan sensibly. For us lesser mortals, this will be a more achievable goal, than for those, born to be athletes and diet guru's.
Exercise? Take the dog for brisk walks daily. No dog? get a treadmill, and stick it in front of the tv. Why, you won't even realise you've done a mile or two, until you've painlessly got through two episodes of Corrie and Eastenders or Newsnight! Turn up the stereo and bop, while you are hoovering away etc.
Food: Cut down on unhealthy monosaturated fats, substitute with olive oil and rape seed saturated fats, grill, rather than fry, jacket spuds, with no butter, and you won't miss it, if you pile your meat/ fish /veg topping on. Oven chips, instead of the chip shop! Five a day of vegetables and fruit, then if you eat sensibly, but not like a health freak, an odd treat, preferably saved for weekends, or if you must, during the week, treat size/ bite size choc, rather than a whole size one (or savoury, handful of almonds etc) and a treat on weekends, maintaining fruit and veg, and not overdoing a gorging fest, just loosening the reins a little. Substitute sugar for honey, if sugar free, isn't to your liking in everything, as its a little healthier than the white processed stuff. Cook your own fresh meals, at least you know what goes into them, and if you are a lazy cook, do so in large quantities and freeze in portions, and voila! A home made chilled convenience meal!
Now go live your new life, and hopefully, you will become healthier and happier, and not even notice you are doing it 🙂

I am of "traditional build" but currently walk 2 and a half hours per day and have low cholesterol and low blood pressure too. Not everybody who is overweight is unhealthy!

Great comment about the Parkrun it is so inclusive of all capabilities but is also giving rise to an astonishing appearance of people running, jogging walking for fun during the week at a level that I have not seen before.

Pity NHS and PHE haven't joined up with TFL (transport for London) to encourage activity. Santander Bikes are not available with travel cards for those who may have paid thousands for them or for the older resident. TFL has actually programmed in inactivity. I've heard people say, "I'm not paying for a Boris Bike when I've already paid for my travelcard, so I get on the bus or tube."
Let's get a little more joined up and help people who live or work in London become more active.
