Taking time out to scroll free

As the Royal Society for Public Health launches its #ScrollFreeSeptember campaign, encouraging people to take a break from social media, Professor Yvonne Kelly from the ESRC International Centre for Lifecourse Studies at UCL, discusses new research on the negative impacts of social media use on young people’s health. She explains how the findings point to the need to limit the time that young people, especially girls, spend on social media.

The ScrollFreeSeptember campaign accompanies the launch of a second parliamentary inquiry in less than 12 months into the impact of social media use on young people’s mental health and well-being. Our Centre will be submitting a range of important new findings to that inquiry which seeks to grow the evidence base in an area where there is a great deal of hot debate, but where little is really known and understood.

For our team of researchers, the first indication that all was not well in the world of social media and young people’s mental health came in 2015 when we found that children who were heavy users of screen-based media were less happy and had more social and emotional problems than their peers who used it moderately. Children who used social media sites for chatting were also less likely to be happy and more likely to have problems than their peers who did not.

In March this year, our widely covered work on the trends for boys’ and girls’ social media use added weight to recent calls from the Children’s Commissioner for England to, as she put it, call time on a “life of likes”. In her report, Anne Longfield argued that there was clear evidence of children finding it hard to manage the impact of online life. She said children as young as eight were becoming anxious about their identity as they craved social media likes and comments for validation.

Social media and girls

Our research, based on the experiences of 10,000 children aged 10-15 who took part in the Understanding Society study, showed that this seemed to be the case particularly for girls who used social media for more than an hour a day. 10 year-old girls in the study who spent an hour or more on a school day chatting online had considerably more social and emotional problems later on – by age 15 – than girls of the same age who spent less or no time on social media. The number of problems they faced also increased as they got older, which was not the case for boys.

It was interesting to note that more girls than boys were using social media and for greater periods of time. At age 15, 43 percent of girls and 31 per cent of boys were using it for between one and three hours per day, with 16 and 10 per cent using it for more than four hours.

We think this tells us something important about the different ways that girls and boys interact with social media. For example, girls may be more likely than boys to compare their lives with those of friends and peers – whether those are ‘filtered’ selfies or positive posts about friendships, relationships or material possessions – these could lead to feelings of inadequacy, lower levels of satisfaction and poorer wellbeing.

The pressures associated with having peers like or ‘approve’ status updates and a perceived fall in or lack of popularity could add further pressure at, what for many teenagers is a tricky time in their lives.

Boys are more likely to be gaming than interacting online in the way just described and that wasn’t covered in this research, so it’s possible that for boys, changes in well-being may be more related to gaming success or skill.

But one of the key takeaways of this research is how social media use as a very young person is linked to lower levels of happiness later on – the effects are not short term – they have longer term consequences and

Social media and depression

More recently, we have turned our attention to the social media experiences of the children in the Millennium Cohort Study (MCS), using information on 11,000 14 year-olds to look at how social media use is linked with depression. We’ve also been asking ourselves what the pathways between these two things might look like, something that’s not really been done before. So, for example, are heavier users of social media getting too little sleep or having trouble getting to sleep because they are checking accounts at bedtime; are they experiencing cyberbullying either as victims or perpetrators; do they appear to have low self-esteem or a negative view of how they look? All these questions can help us better understand what’s at play and come up with better approaches to tackling these problems.

Preliminary findings reinforce the message that girls are particularly vulnerable to the negative effects of social media. Once again we see more girls than boys in this study using social media and for longer periods of time.

Does using social media affect literacy?

A follow up piece of research looks at whether there are links between the amount of time young people spend on social media and their levels of literacy. Findings suggest a link and that this is the same for boys and girls.

In this research we look at whether the more time young people spend on social media, the less time they have for the things that might improve their literacy such as reading for enjoyment and doing homework.

There are some clear messages from our research so far:

  1. Heavy users of social media are less happy and have more problems at school and at home – interventions to help them limit and manage their social media use better are likely to be important
  2. Girls are particularly vulnerable to the negative effects of social media and may be an important group to focus on among those looking to mitigate thse effects
  3. More hours spent on social media appear to impact negatively on young people’s wellbeing and could have knock on effects for their longer term prospects at school and work

Social media companies have been accused by the former Health Secretary Jeremy Hunt among others of turning a blind eye to the problem and the chief medical officer Dame Sally Davies has been asked to recommend healthy limits for screen time.

Our research indicates that it may indeed be time for recommended healthy and safe limits of social media use, that a focus on girls, especially initiatives to boost their mental health could help mitigate some of the negative effects.

The RSPH is hoping that going scroll free this September might give us all a chance to get our social media use a little more balanced, to think about the benefits to be enjoyed and the negatives to be avoided.

As well as pausing to think about our social media use and how it affects us, it will be an opportunity to examine the facts of the matter, a time to digest new, solid evidence that these large scale studies can help us with and consider the potential longer term costs and consequences of doing nothing.

The forthcoming inquiry hopes to inform “progressive and practical solutions”, including a proposed industry Code of Practice and tools for educators, parents and young people themselves to help them enjoy the benefits and eliminate the negative effects of their social media. We wholly support those efforts and hope they result in positive changes that will make campaigns like ScrollFreeSeptember unnecessary in the future.

Calling time on a life of likes could be key to girls’ happiness

There have been increasing calls in recent months for more to be done to prepare children for the emotional demands of social media. Just a few weeks ago, the Government’s Science and Technology Committee announced an inquiry into the impact of social media on the health of young people. But do girls and boys use social media as much as each other and is all this time spent Facebooking, Whatsapping and Snapchatting having a detrimental effect on their happiness and well-being? Cara Booker from the University of Essex, in collaboration with collleagues from UCL, has been looking at trends in social media interaction and well-being in nearly 10,000 10-15 year-olds in the UK over a 5 year period. Their findings indicate that girls may be at greater risk and therefore a focus for those looking to intervene to protect and promote children’s happiness.

The Government’s inquiry into the impact of social media on the health of young people comes hard on the heels of a report from the Children’s Commissioner for England, which says that children between the ages of 8 and 12 find it hard to manage the impact of online life and become anxious about their identity as they crave ‘likes’ and comments for validation. 

An explosion in digital and social media platforms has revolutionised the way we all consume media with a recent report showing that young people aged 12-15 spending more time online than they do watching TV. Indeed, it seems a long time ago that parents’ prime concern around media was how much or what kind of TV their child was watching.

All these major developments have taken place at a time when we also know that young people are becoming less and less happy. In the most recent United Nations Children’s Fund report, UK adolescents are ranked in the bottom third on overall well-being, below Slovenia, the Czech Republic and Portugal.

Of course, it’s important to remember that the internet has done a great deal of good for children: connecting them with friends and family who may be far away, providing great opportunities to widen horizons and learn new things. These things have been shown in other studies to be linked with increased levels of happiness and well-being in children

On the negative side, social media use has been linked with obesity, cyberbullying, low self-esteem and lack of physical activity, all things that can affect the lives of children as they move through school and into adulthood and work.

Social media experiences

Young people who took part in the Understanding Society survey, were asked if they belonged to a social web-site and then how many hours they spent ‘chatting’ or ‘interacting with friends’ on a normal school day. They could select a range of responses from none to more than 7 hours.

At age 10, 50 per cent of girls and 55 per cent of boys said they had no internet access or spent no time on social media. At 15 years, this dropped to 8 and 10 per cent respectively.

Ten per cent of ten year old girls reported spending one to three hours a day (compared with 7 per cent of boys) and this increased to 43 per cent of girls at age 15 (and 31 per cent of boys).

At age 10 only a very small percent of girls/boys were spending 4 hours plus a day on social media. But by the age of 15, that rose to 16 per cent of girls and 10 percent of boys.

Levels of happiness 🙂 🙁

Young people who took part in the survey were asked about satisfaction with schoolwork, friends, family, appearance, school and life as a whole and this was used to create an overall happiness score for them.

They were also asked about any social and emotional difficulties they might be facing using the well-established Strengths and Difficulties Questionnaire (SDQ) with a higher score indicating more problems.

For both boys and girls, levels of happiness decreased between the ages of 10 and 15, however the decrease was greater for girls than for boys. Additionally, whilst SDQ scores increased for girls between the ages of 10 and 15, they decreased for boys.

10 year-old girls who spent an hour or more on a school day chatting online had higher SDQ scores (more social and emotional problems) than girls of the same age who spent less or no time on social media. In addition, the score (number of problems) increased as they got older.

Why the gender difference?

So why the gender difference? This is hard to unpick and not something we were able to look at specifically in our research. It may say something about the different ways that girls and boys interact with social media. For example, girls may be more likely than boys to compare their lives with those of friends and peers – whether those are ‘filtered’ selfies or positive posts about friendships, relationships or material possessions – these could lead to feelings of inadequacy, lower levels of satisfaction and poorer wellbeing.

The pressures associated with having peers like or ‘approve’ status updates and a perceived fall in or lack of popularity could add further pressure at, what for many teenagers is a tricky time in their lives.

Boys are more likely to be gaming than interacting online in the way just described and that wasn’t covered in this research, so it’s possible that changes in well-being may be more related to gaming success or skill.

What needs to change?

It’s clear that social media is no short-lived phenomenon and our research indicates that girls, possibly because of the way in which they interact online and the amount of time they spend doing so could be at greater risk.

In her report, A Life of Likes, the Children’s Commissioner Anne Longfield has called for more to be done to check and stop underage use and to prevent children becoming over dependent on likes and comments and “adapting their offline lives to fit an online image”, something she believes can lead to an anxiety about ‘keeping up appearances ‘ as they get older.

Our research really adds weight to recent calls for the technology industry to look at in-built time limits. Young people need access to the internet for homework, for watching TV and to keep in touch with their friends of course, but a body of evidence is emerging to show that substantial amounts of time spent chatting, sharing, liking and comparing on social media on school days is far from beneficial especially for girls.

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.”

 

 

Screen use at seven: overweight at 11. Why it’s time to say no to a TV in the bedroom for children

Since the launch of the Childhood Obesity Strategy in 2016, there has been much attention focused on the so-called ‘Sugar Tax’. The March 2017 Budget saw confirmation that sugary soft drinks would be taxed in an attempt to combat rising levels of obesity. This is an important move that has been met with widespread approval from public health professionals. Still, obesity is hugely complex and there are many other things at play in addition to the sugary drinks and snacks that children may consume. Researchers at UCL have been looking in detail at different factors associated with obesity and, in a recent paper, find that children who have a television in their bedroom have higher BMI and more body fat than those who do not. Lead researcher, Anja Heilmann, explains the research and why saying no to a TV in the bedroom could be another important strategy in combatting childhood obesity.

As our TV screens have got flatter, our children have got fatter. There is no getting away from it! Screen-based activities play a central role in our children’s lives. At a very young age, they have unparalleled access to television screens, computers, game consoles and a host of mobile devices. Among 5 to 11 year-olds, TV is still the most consumed medium, with gaming coming second.

At the same time, childhood obesity is not just a national, but a global health worry. In 2014/15 a third of 11 year-old children in England were overweight and a fifth were obese.

Research has repeatedly reported a link between TV viewing and obesity, but although some has hinted at the idea that a television in a child’s bedroom might exacerbate the problem, the evidence here has been rather contradictory. Other plausible pathways could include eating unhealthy snacks whilst watching TV, exposure to food advertising and insufficient and poor quality sleep.

Using information from the Millennium Cohort Study (MCS), which has followed the lives of more than 18,000 children born around the turn of the century, we had the opportunity to see whether having a TV in their bedroom when they were age 7 was, in any way, linked with a child being overweight when they were 11 years old. In other words, we wanted to get to grips with whether there were implications over a child’s lifetime of their screen use and if so, what those implications were.

Useful information

Using trained interviewers, the MCS collects a wide range of useful information including the independently measured height, weight and body fat of a child. These provided us with a set of obesity-related measurements: weight, Body Mass Index (BMI) and Fat Mass Index (FMI), a powerful set of measures for overweight and obesity.

When the children were age seven, parents were asked if their son or daughter had a TV in their bedroom, how many hours they spent watching TV or DVDs and how much time they spent playing on a computer.

 At age 7, more than half of the 12,556 boys and girls we looked at in our research had a TV in their room and it was these children who were more likely to be overweight when they turned 11 when we compared them with those without a TV. They were also more likely to have higher BMI and FMI. In total, a quarter of the boys and nearly a third of the girls were overweight at age 11 and the links between having a TV in the bedroom and overweight were stronger for the girls.

Another strength of the research is that we controlled for the child’s BMI at age 3 and maternal BMI, that way adjusting for genetic factors, as well as food environment in the family. We also adjusted for family income and mother’s education – both of which are important as overweight/obesity is socially patterned, as is TV use.

Interestingly, there was no link between overweight and the time a child, whether they were a boy or a girl, spent playing on a computer.

Clear link

So, given the size of our sample and the robustness of the methods employed here, we can say with considerable confidence that there is a clear link between having a TV in the bedroom as a young child and being overweight a few years down the line. For girls, this represents a 30 per cent increase in the risk of being overweight at 11 compared with their peers who do not have one. For boys the risk increases by around 20 per cent.

Another interesting point to note is that the size of this risk or effect is about the same as that of other things shown to be linked with obesity, such as not being breastfed and being physically inactive.

Nevertheless, policy makers looking to create and implement strategies to reduce obesity should certainly consider building access to television screens in children’s bedrooms into their thinking. Specific initiatives focused on young girls could also be important.

Meanwhile, for parents who may consider it a good idea for a young child to have their own TV in their bedroom or feel under pressure to provide one, the message is quite clear: resist the idea and you may be doing even more to set your child on a healthier path into their teenage years and beyond.

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.

Get up, get out, get active!

Just what are the long term effects of being a couch potato as a youngster? New research using the  1970 British Cohort Study shows we may reap what we sow if we don’t switch off the television or the Playstation and get ourselves and our kids off the couch and active. Dr Mark Hamer from UCL spoke to Child of our Time about the research.

“Childhood correlates of adult TV viewing time: a 32-year follow-up of the 1970 British Cohort Study”, by Lee Smith, Ben Gardner and Mark Hamer of UCL’s Department of Epidemiology and Public Health. It will be published in a future issue of the Journal of Epidemiology and Community Health.
