Wheezing: Can breastfeeding for longer make a difference?

Public health bodies put a lot of effort into encouraging mothers to breastfeed, and for good reasons. Successive studies have shown breastfeeding has a range of health benefits, including a lower risk of wheezing illnesses, which can be linked to asthma. But which of these illnesses are most likely to respond? Is a breastfed child less likely to develop wheezing after age five, or age seven, for instance? Or is the protective effect mainly measurable only in younger children? Professor Maria Quigley from the National Perinatal Epidemiology Unit at the University of Oxford, along with colleagues at Oxford and UCL, has been looking at how and when breastfeeding is associated with wheezing.

Asthma is the most common chronic condition affecting children and young people in the UK. It’s the most common reason why children are admitted to hospital, and sadly each year a few still die from the condition. According to the British Lung Foundation three children in every hundred under the age of five have been diagnosed with asthma at some point; and by age 10 that figure rises to one in 10.

There’s no cure, and so the priority for public health bodies has been to understand the disease better, to manage it better and to learn more about the factors that can protect us from it. One such protective factor is breastfeeding: two recent pieces of research have shown there is a lower risk among breastfed children, but that the effect is stronger among the very young – both for asthma and for wheezing, which has many causes and which does not necessarily develop into asthma.

Childhood wheezing can follow a variety of patterns – it can set in early but clear up before adulthood, for instance, or it can start later but continue into later life. Some wheezing will start in childhood and will continue.

Millennium Cohort Study

We wanted to look at how breastfeeding might affect these different types, so we used data from the Millennium Cohort Study, which has followed the lives of almost 19,000 children born in the UK between September 2000 and January 2002. Their parents were interviewed when they were 9 months old, and again when they were 3, 5, 7 and 11 years.

Our study focused on just over 10,000 children who were seen at all of those points and who were the product of single as opposed to multiple birth. Mothers were asked whether they had tried to breastfeed, and for how long their children had been breastfed.

Among our sample, seven out of 10 children had been breastfed: a little more than one in ten of the study sample for less than a week; a fifth for between one and three weeks, just over one in six for three to six months and around a quarter for six to nine months.

We found that at age 9 months, 6.5 per cent of children had a history of wheezing. At age 3 years, 19.5 per cent had such a history in the past year. As the children got older, though, this proportion decreased – 16 per cent at age five, 11.8 per cent at age seven and 11.4 per cent at age 11.

Overall, 37 per cent of children had suffered from wheezing at least once between 9 months and 11 years. A little under a fifth (18.8 per cent) had wheezing at younger age which cleared up when they got older, while 6.2 per cent had wheezing which started later and 11.8 per cent had persistent wheezing.

Feeding and wheezing

When we looked at the association between breastfeeding and wheezing, we found the children who had been breastfed for longest were less likely to suffer from wheezing.

But this effect lessened with time. For example, those breastfed for six to nine months were less likely to wheeze between the ages of nine months and five years, but by the age of 11 this group had no significant advantage over those who were breastfed for less time.

What does our study tell us about the relationship between breastfeeding and wheezing? The picture is a complex one. There are many causes of wheezing and of asthma, and those causes change over time. So in order to draw firm conclusions about cause and effect, we would need a much more complex dataset. It would be interesting, for instance, to look at clinical information on children’s allergies or their lung function.

But what we can say is that age matters – in order to understand how breastfeeding affects the development of wheezing during childhood, we must take a longer and more nuanced view.

Off the scales: time to act on childhood obesity

By 2050, it is said that obesity could cost the NHS almost £10 billion a year, with the full economic cost rising from around £27 billion today to £50 billion by then. Today, the Centre for Social Justice (CSJ) publishes its report, Off the scales: time to act on childhood obesity. It calls on the Government to put prevention, health, inequality and cross-departmental collaboration at the heart of its efforts to tackle childhood obesity, drawing particular attention to the need to address the question of why poorer children are at ever greater risk of being obese. It’s a question researchers at the ESRC International Centre for Lifecourse Studies at UCL, including our editor Yvonne Kelly, have been among the first to address.

There have been numerous major studies on childhood obesity over the past 10 years, many of which have shown the links with poverty. But our research looks specifically at why children from disadvantaged families are significantly more likely to be obese than their better off peers.

To examine this as robustly and rigorously as we could, we used data from the Millennium Cohort Study (MCS) which has tracked the lives of nearly 20,000 children from across the UK since the turn of the century. Using a range of measurements taken when the children were aged 5 and 11 together with detailed information about their backgrounds and family circumstances, we were able to demonstrate just how key poverty was in respect of their obesity.

At age 5, poor children were almost twice as likely to be obese compared with their better off peers. By the age of 11, the gap had nearly tripled.

Knowing as we do that obese children are less likely than their peers to grow into economically successful adults and that obesity is clearly linked with a range of chronic diseases, it’s reasonable to say that for these children, the future is far from bright. From a policy perspective it is also clear that unless the gap between rich and poor children can be closed the chances of reducing the overall obesity trend, as the Government states it is committed to doing, are pretty slim.

How is poverty linked to obesity?

The MCS collects a broad range of data, allowing us to dig beneath these headline numbers to tease out some of the specific ways in which relative poverty in childhood leads to an increased risk of obesity.

To examine this question of whether a parent’s own lifestyle might have a role, we looked at factors previously shown to be linked to the increased risk of obesity, such as whether the mother smoked during pregnancy, how long she breastfed for and whether the child was introduced to solid food before the age of four months.

We could also factor in the degree to which a mother was herself overweight or obese and assess children’s physical behaviour, such as how often they exercised, played and how many hours they spent watching TV or playing on a computer, and the time that they went to bed. We looked at whether the child skipped breakfast, how much fruit they ate and how often they had sweet drinks.

A lot of these factors were relevant. A mother’s behaviour when her child was very young was certainly important. Markers of an ‘unhealthy’ lifestyle here could mean as much as a 20 per cent additional risk of obesity for a child.

Obese and overweight children living in poor families were more likely to have mothers who did not breastfeed or breastfed for a shorter duration, who introduced solid foods early in infancy, who smoked during pregnancy, and who were overweight or obese. The poorest children were also more likely to spend more time watching TV and using a PC (and so have greater exposure to food and drink advertising), experience later and more irregular bedtimes, do less sports and be more physically inactive, engage less in active play with their parent, live in an area without a playground, and not have breakfast every day.

5-year-olds from poorer families were also much more likely to gain excess weight up to age 11 than richer children, leading us to conclude that the earlier certain risk factors can be challenged and the appropriate support provided for the least well off families, the greater the chance of positive impact on the risk of obesity and in a reduction in inequality.

Pathways to obesity

More recently we have identified four BMI trajectories for children. The good news is that 80 per cent of them are on a stable path where, on average, from when they’re born through to age 11, they are not overweight.

There is a small group of children who are obese at age 3 but then join the stable group by age 7. We call them the ‘decreasing’ group. There is a ‘moderate increasing group’ (13.1 per cent) where children are not overweight at age 3 but whose BMIs increase throughout childhood into the overweight (but not obese) range. Finally we have a ‘high increasing’ group of children (2.5 per cent) who are obese at age 3 and whose BMI continues to increase.

From an inequality perspective, what’s most striking here is that the wealthiest children are least likely to be in the ‘moderate increasing’ BMI group whilst the poorest children are more than twice as likely to be on the high increasing path.

Today’s CSJ report agrees with our analysis that early intervention is key and, in line with it, proposes three key early years intervention opportunities to ensure children get the healthiest start possible before they reach primary school age.

The report acknowledges that the Government is already trying to persuade families to eat more healthily and take more exercise. But it has joined a body of voices critical of the Childhood Obesity Plan, which, it believes, “fails to put reducing inequality as a goal … despite acknowledging that the childhood obesity burden falls hardest on the poorest children.”

Certainly our body of evidence indicates that policy makers need to acknowledge and address inequality as a root cause of obesity. Doing something about the structural factors in people’s lives is what is needed rather than ‘tinkering around the edges’ of the problem.

Today the CSJ asks why there are disproportionately high levels of obesity, particularly childhood obesity, in our most deprived communities. Our research has gone some way to answering that question, and makes it clear that there is no simple one-stop shop solution.

Obesity is caused by a combination of environmental, biological, cultural and psychological factors, where one factor does not dominate and yet our obsessional search for the ‘one thing’ that can tackle obesity continues. If the Government is going to reduce obesity rates, it will indeed, need to introduce multiple bold measures in tandem across the entire ecosystem and recognise that success may only be measurable after a few years.

An equal start: longitudinal evidence to support children’s healthy development

Using longitudinal evidence to support children’s healthy development and give them an equal start in life is the subject of our editor Yvonne Kelly’s keynote address at the Growing up in Ireland Annual Conference in Dublin today.

Her talk discusses findings from the most recent of the British ‘birth ‘ cohort studies – the Millennium Cohort Study that have so far informed policy development. They include work by researchers at the ESRC Centre for Lifecourse Studies where Yvonne is based on alcohol consumption during pregnancy, breastfeeding and the introduction of solid foods, the physical punishment of children , childhood obesity, reading to children in the early years, and sleep patterns throughout childhood.

She will also share work with the potential to inform future policy challenges such as young people’s drinking, social media use and mental health.

Ahead of her talk, she said:

“It is well established that what happens in the early years of life has long-lasting consequences for health and social success across the lifespan. Stark social inequalities in children’s health and development exist and emerge early in life. It is therefore crucial to identify potential tipping points and opportunities for intervention   during childhood with the potential to affect change and improve life chances.”

 

 

Don’t let the kids get jet-lag: why regular bedtimes are key to a happy healthy childhood

The very best of sleep medicine and research is being presented at the World Sleep Congress in Prague this week. Among that research are findings from work by Child of our Time Editor, Professor Yvonne Kelly and colleagues at the ESRC International Centre for Lifecourse Studies. They have been trying to find out what it is about sleep that matters most when it comes to giving children the best possible start in life. Here Yvonne explains what they have found to date and why regular bedtimes are key to a healthy happy childhood.

What happens in the early years has profound implications for what happens later on in life. Thousands of research papers, many of them using the wonderful rich data in the British Birth Cohort studies, have documented the enduring impacts of the way we live our lives as children on how we fare later on. Children who get a poor start in life are much more likely to experience poor outcomes as adults, whether that’s to do with poor health or their ability to enjoy work and family life later on.

So what has all that got to do with getting enough sleep as a toddler you might ask? Well our research shows it is one of a number of important factors related to getting children off to the best possible start in life and here’s why.

Recommended sleep

The National Sleep Foundation recommends that toddlers should get around 11 to 14 hours sleep every day. For 3-5 year-olds, the recommendation is 10-13 hours and it suggests 9-11 hours for children once they’re at primary school. But is it all about the number of hours sleep children get, or is there more to it than that? Those are the questions we have been addressing in our research into children’s sleep and how it ties in with how they get on at home and at school across the first decade of their life.

Digging into one of those studies mentioned earlier, the Millennium Cohort Study, which has followed the lives of some 20,000 children since the turn of the century, we found that it’s not just the number of hours a child sleeps that matters, but also having consistent or regular bedtimes.

First we looked at the relationship between regular and irregular bedtimes and how the children got on in a range of cognitive tests. The results were striking. Children with irregular bedtimes had lower scores on maths, reading and spatial awareness tests.

Parents who took part in the MCS were asked whether their children went to bed at a regular time on weekdays. Those who answered “always” or “usually” were put in the regular bedtime group, while those who answered “sometimes” or “never” were put in the irregular bedtime group.

Interestingly, the time that children went to bed had little or no effect on their basic number skills, and ability to work with shapes. But having no set bedtime often led to lower scores, with effects particularly pronounced at age three and the greatest dip in test results seen in girls who had no set bedtime throughout their early life.

The key to understanding all this is circadian rhythms. If I travel from London to New York, when I get to there I’m likely to be slightly ragged because jet lag is not only going to harm my cognitive abilities, but also my appetite and emotions. That’s for me, an adult. If I bring one of my children with me and I want them to do well at a maths test having just jumped across time zones, they will struggle even more than I will. The body is an instrument, and a child’s is especially prone to getting out of tune.

The same thing happens when children go to bed at 8 p.m. one night, 10 p.m. the next and 7 p.m. another — we sometimes call this a “social jet lag effect.” Without ever getting on a plane, a child’s bodily systems get shuffled through time zones and their circadian rhythms and hormonal systems take a hit as a result.

Bedtimes and behaviour

Having established the importance of sleep to a child’s intellectual development, we turned our attention to the relationship between regular bedtimes and their behaviour.

At age 7, according to parents and teachers, children in the MCS who had irregular bedtimes were considerably more likely to have behaviour problems than their peers who had a regular bedtime. In addition, the longer a child had been able to go to bed at different times each night, the worse his or her behaviour problems were. In other words the problems accumulated through childhood.

One really important piece of good news was that we found that those negative effects appeared to be reversible, so children who changed from not having to having regular bedtimes showed improvements in their behaviour. There seems to be a clear message here that it’s never too late to help children back onto a positive path and a small change could make a big difference to how well they get on. Of course, the reverse was also true so the behaviour of children with a regular bedtime who switched to an irregular one, worsened.

Bedtimes and obesity

In a follow up study, which looked at the impact of routines including bedtimes on obesity, we reported that children with irregular bedtimes were more likely to be overweight and have lower self-esteem and satisfaction with their bodies.

In fact, of all the routines we studied, an inconsistent bedtime was most strongly associated with the risk of obesity, supporting other recent findings which showed that young children who skipped breakfast and went to bed at irregular times were more likely to be obese at age 11.

Even children who ‘usually’ had a regular bedtime were 20 per cent more likely to be obese than those who ‘always’ went to bed at around the same time.

So we have a body of robust evidence now that shows very clearly that regular bedtimes really matter when it comes to a child’s health and development over that important first decade of their life.

Providing that evidence in the form of advice to parents and all those caring for young children alongside recommended hours of sleep could make a real difference, helping protect our children from ‘social jet-lag’ and getting them off to a flying start instead.

Equally protected children: one step closer

In 2015 UCL researchers Anja Heilmann, Yvonne Kelly and Richard Watt produced a report, which showed that there was ample evidence that physical punishment can damage children and escalate into physical abuse. Together with the children’s charities that commissioned the report, they called for urgent action to provide children with the same legal protection against violence that British adults enjoy. The report was at the heart of Scottish MSP John Finnie’s proposed Children (Equal Protection from Assault) Bill which the Scottish Government have just announced that they will support in their programme for the coming year. The Bill would make Scotland the first UK country to outlaw all physical punishment by removing the defence of “justifiable assault” of children, and giving them the same protection as adults. Lead researcher, Anja Heilmann, reflects on the news and what she hopes it might mean for the human rights of children in Scotland and elsewhere.

On 11 May 2017, John Finnie MSP proposed a Bill to the Scottish Parliament to “give children equal protection from assault by prohibiting the physical punishment of children by parents and others caring for or in charge of children”.

After a three month consultation, which received more than 650 responses, the majority positive (75 per cent), that Bill became part of the Scottish Government’s plans for the next year, as Nicola Sturgeon announced she would not oppose it.

If passed, the Bill will prohibit the physical punishment of children by ending the existing common-law position that physical punishment by parents can be defended as reasonable chastisement and therefore be lawful. The Bill will not create a new criminal offence, as the common law offence of assault will apply (with a modification removing the reasonable chastisement defence).

It’s a far cry from similar efforts made in Scotland in 2002 to prohibit the physical punishment of children under the age of three. Back then, not only did a majority of MSPs reject the idea, but it was branded as “ridiculous” and an unwelcome intrusion into family life by many parents and the media.

15 years on it seems attitudes may have changed significantly. In the foreword to the Bill, John Finnie himself said:

“We would no longer consider it acceptable…. to allow our children to roam freely in the back of the car when going on a journey. Neither would we dream of taking them to a cinema if they had to watch a film through a fug of cigarette smoke … Attitudes towards these and many other fundamental societal issues have dramatically changed.”

Those attitudes changed as the result of a clear presentation of the evidence – the hard facts about the damage that those behaviours could cause.

We believe that, in this case, our evidence has made it clear for all to see that hitting children can not only damage them, but it carries the risk of escalation into physical abuse. It is a clear violation of international human rights law and children should and must be afforded the same rights as adults in this respect.

Overwhelming evidence

The evidence for the detrimental effects of physical punishment is vast and consistent. In short, our summary of the available evidence showed that physical punishment was related to increased aggression, delinquency and other anti-social behaviour over time. It also showed the more physical punishment suffered by a child, the worse the subsequent problem behaviour.

There was also a clear link between physical punishment and more serious child maltreatment and negative effects continued into adulthood, including problems of drug and alcohol dependency.

Half-hearted responses to recent human rights rulings condemning the physical punishment of children need to become wholehearted changes to the law, not tinkering that does just enough to meet the minimum requirements of those judgments rather than properly respect the rights of children.

The UN Committee on the Rights of the Child is unequivocal – all forms of corporal punishment of children are unacceptable. Let’s hope the Scottish Parliament can find the courage to make that statement a reality and show the rest of the UK the way.

As Martin Crewe of Barnardo’s Scotland stated:

“This is a huge step forward and sends a very clear message about the kind of Scotland we want to see for our children.”

Personally, I am hoping it’s a kind of Scotland and indeed UK, we WILL see in the not too distant future and I appeal to all MSPs to listen to the evidence and support the Bill.

Equally Protected? A review of the evidence on the physical punishment of children by Dr Anja Heilmann, Professor Yvonne Kelly and Professor Richard G Watt was commissioned by NSPCC Scotland, CHILDREN 1st, Barnardo’s Scotland and the Children and Young People’s Commissioner Scotland.

Why reading is key to giving our kids a great start in life

A growing body of research is pointing to how important and valuable reading is in giving children the best possible start in life, not just for academic success but more broadly including for a child’s mental health and happiness.

In this special episode of the Child of our Time Podcast, Professor Yvonne Kelly is joined by Jonathan Douglas, CEO of the National Literacy Trust and researcher Christina Clark, also from the  Trust. They discuss important new evidence about the benefits of reading for individual children and in addressing social inequalities.

Tackling the childhood obesity epidemic: Can regular bedtimes help?

Nearly one in five 10 and 11-year-olds in England is obese, according to NHS figures. With childhood obesity posing not just a nationwide, but a worldwide health threat, public health researchers around the globe are striving to establish which aspects of a young child’s life might set them on a path to being obese later on. Associate Professor Sarah Anderson from The Ohio State University College of Public Health and colleagues from University College London outline the first research to try to disentangle the role of children’s routines and behaviour at age 3 on obesity at age 11 and show that bedtime routines and learning to manage emotions really do matter.

The UK’s Chief Medical Officer Professor Dame Sally Davies has warned that the health of millions of children is in jeopardy and is concerned that being overweight is becoming the norm. She fears half the population could be obese by 2050 at a cost of billions of pounds to the health service and wider economy.

The latest statistics highlight a stark contrast between the wealthiest and poorest families, with childhood obesity rates in the most deprived areas more than double those in the most affluent areas.

Despite the publication in August 2016 of the Government’s long-awaited childhood obesity strategy, charities and health organisations remain highly critical, describing it as a watered-down effort that puts business interests ahead of those of public health. Even the recent introduction of the so-called ‘sugar-tax’ on soft drinks has been met with scepticism in some quarters.

To help inform public health strategies going forward, our researchers looked at the bedtime, mealtime and tv/video routines of very young children and their emotional and behavioural development to see if, at this early stage, it is possible to identify those most at risk of becoming obese.

The study includes information on nearly 11,000 children collected through the UK Millennium Cohort Study (MCS). When the children were three, their parents reported whether children always, usually, sometimes, or never or almost never had a regular bedtime and mealtime, and the amount of television and video they watched each day.

They were also asked a series of questions about the child’s behaviour during the previous six months. Questions were about how children cope with emotions and their persistence and independence in play, including how easily the child became frustrated and whether they sought help from adults when faced with a difficult task. This was to get an idea of how well the child was able to ‘self-regulate’ their behaviour in these areas.

Regular routines

Children with regular bed and mealtimes and who watched less television were better able to control their emotions than their peers with less regular and consistent routines.

At 11-years-old, 6.2 per cent (682) of the children in the MCS were obese, with obesity more common in lower income and less educated families.

Of the routines we studied, inconsistent bedtime was most strongly associated with the risk of obesity, supporting recent findings by our UCL colleagues which showed that young children who skipped breakfast and went to bed at irregular times were more likely to be obese at age 11, stressing the importance of adequate sleep for preventing childhood obesity.

Even children who ‘usually’ had a regular bedtime were 20 per cent more likely to be obese than those who ‘always’ went to bed at around the same time.

Regular bedtimes and obesity

Surprisingly, toddlers with irregular meal times had a lower risk of obesity at age 11. Once other routines were factored in, television viewing was not related to obesity, although it is important to note that computer use was not taken into account, and the media environment for young children today is different than it was when children in MCS were young.

There was also a clear link between lower levels of emotional self-control in early childhood and obesity later on. Children with poor emotion regulation at age 3 were over 50 per cent more likely to be obese when studied at age 11.

Children’s level of persistence and independence was not linked to later obesity, however, and it is possible that this could be explained by the relative immaturity of the parts of the brain responsible for a child’s cognitive compared with their emotional development at this young age.

Strongest risk

Our study is the first to look at the relationship between a child’s routines, their ability to regulate their emotions and behaviour and how these factors work together to predict obesity.

The two strongest risk factors for obesity were irregular bedtime and a poor ability to control emotions and these were completely independent of each other. In other words, the link between bedtimes and obesity could not be explained away by a child’s inability to regulate their emotions.

There is a need to look more closely at the timing and regularity of children’s mealtimes and how they impact obesity later on, as we think there may be a lot more factors at play than we have considered here. We also need to better understand how the development of emotional and cognitive self-regulation interacts with metabolic, behavioural and social pathways to obesity.

However, our study supports previous research showing that children’s emotional regulation develops within a family context which includes routines.

One message from our study is crystal clear. To be effective, obesity strategies must target early childhood, and must find a way to support parents, especially those from the most deprived areas, to introduce and maintain consistent bedtimes and other home routines, as well as help children regulate emotions and respond to stress.

Another key message is that one size does not fit all. There is a lot going on in children’s lives that is important for their health and development. Saying that, it would seem that getting our children to bed at the same time every night could be a simple, cost-effective tool in the tool-kit to get them off to a good start and maybe in the larger battle against obesity.

Giving children the best possible start – what matters most?

Child of our Time Editor Yvonne Kelly spoke to a 500-strong audience of politicians and professionals in Gothenburg recently on what matters when it comes to giving children the best possible start in life.

Yvonne was the keynote speaker at the conference hoping to identify the best strategies for making Gothenburg a more equal and socially sustainable city.

Yvonne, Professor of Lifecourse Epidemiology at the ESRC International Centre for Lifecourse Studies at UCL  explained which factors are most closely linked with a child’s health and well-being and presented her research findings on children’s verbal skills, behaviour, bedtimes, reading and obesity.

Putting a SPRING in the step of mums-to-be

Making sure that mums-to-be are in the best possible health is key to ensuring their baby gets the best possible start in life. But what sorts of things can help them achieve that? In this episode of the Child of our Time Podcast, Professor Hazel Inskip from the MRC Lifecourse Epidemiology Unit at the University of Southampton, talks about an ongoing trial making use of healthy conversations and Vitamin D supplements to try to improve the diet of just pregnant women.

Better start for children

Giving children the best possible start in life is the topic of a keynote talk today by our editor Yvonne Kelly.

Yvonne will be presenting a range of new evidence from the ESRC International Centre for Lifecourse Studies  to politicians, business leaders, and other professionals and key decision makers at an event discussing how Gothenburg can be made an equal and socially sustainable city.

Yvonne will talk about the factors which are most closely linked with a child’s health and well-being and present findings on children’s verbal skills, behaviour, bedtimes, reading and obesity. She will make the case that signs of social inequalities are evident early in a child’s life and that it is important to intervene early to tackle those inequalities.
