As weight-busting January came to an end it brought to light a new, hard-hitting report from the WHO Commission on Ending Childhood Obesity (ECHO), with the alarming headline that, globally-speaking, at least 41 million children aged under five years are obese or overweight (1).

Applying the emergency brake on obesity: Whose role is it?
Unsurprisingly, The ECHO report, based on a review of the evidence, highlights childhood obesity as a complex and multidimensional problem. However, according to the report, the greatest obstacle to effective progress on reducing childhood obesity is a lack of political commitment and a failure of governments and other actors to take ownership, leadership and necessary actions. The WHO calls on governments to take effective leadership on obesity by incorporating large-scale cultural environmental and behavioural change without which change simply will not happen.

The knowns
We know that obesity has a massive impact on a child’s quality of life, from physical as well as psychological perspectives; studies also show that obese children face significant risk of obesity in adulthood, which itself poses major health and economic consequences for families and wider society (2).

The report paints a bleak picture that the prevalence of children being overweight under the age of five has risen, from 4.8% in 1990 to 6.1% in 2014, or an increase of 10 million children. On closer scrutiny, the statistics reveal that the most significant change in prevalence has been in Asia and Africa, driven by globalisation and urbanisation leading to obesogenic environments. Another major driver highlighted was the marketing of ‘unhealthy foods and non-alcoholic beverages’ which feature heavily in the recommendations.

The answers
The report proposes a set of policy recommendations to address three strategic objectives:

  1. To tackle the obesogenic environment and norms.
  2. To reduce the risk of obesity during critical periods in the life-course —preconception and pregnancy, infancy and early childhood, and older childhood and adolescence.
  3. The provision of treatment for children who are obese to improve their current and future health. To unpack this further, six broad recommendations are highlighted:Ending childhood obesity

1 Promote intake of healthy foods
Implement comprehensive programs that promote the intake of healthy foods and reduce the intake of unhealthy foods and sugar-sweetened beverages by children and adolescents.

2 Promote physical activity
Implement comprehensive programs that promote physical activity and reduce sedentary behaviours in children and adolescents.

3 Preconception and pregnancy care
Integrate and strengthen guidance for the prevention of non-communicable diseases with current guidance on preconception and antenatal care.

4 Early childhood diet and physical activity
Provide guidance on, and support for, healthy diet, sleep and physical activity in early childhood and promote healthy habits and ensure children grow appropriately and develop healthy habits.

5 Health, nutrition and physical activity for school-age children
Implement comprehensive programmes that promote healthy school environments, health and nutrition literacy and physical activity among school-age children and adolescents.

6 Weight management
Provide family-based, multi component, lifestyle weight management services for children and young people who are obese.

While the report highlights, the limited potential of any single intervention to provide a solution, within these overarching recommendations are more specific targets, focussed on tackling the obesogenic environment.

Targets for the food industry feature prominently. Within the first recommendation, there is a call to implement ‘effective taxation on sugar-sweetened beverages’ and to implement context-specific nutrition information, and ‘interpretive’ front-of-pack labelling. The food and drink industry, retailers and marketing stakeholders are called upon to clampdown on junk food marketing with the report recommending that advertisements for ‘unhealthy products’ should be banned from children’s TV, schools and sports facilities. Sizing up is also singled out as a particular issue to address and there is scope and opportunity for the industry to address appropriate portion sizes.

Schools also offer a key opportunity for action and the report’s recommendations focus on: standards for school meals; elimination of so-called ‘unhealthy foods’, such as sugar-sweetened beverages and energy-dense, nutrient-poor foods, in the school environment; informed nutrition education as part of the core curriculum; and ensuring levels of physical activity for all children, meet current recommendations, with comprehensive programmes that reduce sedentary behaviours in children.

Similarly, health professionals have a major role to play if the recommendations are to be in any way implemented which will take considerable investment in the work-force to achieve the skill-sets required, as well as the resources. The roles that schools and health professionals have to play can only be realised by ensuring that there are measures and funding in place to support them. Even before birth, the behavioural and biological responses of a child to the obesogenic environment can be shaped by processes (3). x7Hanson, MA and Gluckman, PD. Early developmental conditioning of later health and disease: physiology or pathophysiology?. Physiol Rev. 2014; 94: 1027–1076 CrossRef | PubMed | Scopus (30)See all References7 Having clear guidelines which start to tackle that environment is a starting point with independent research being used to show what works. This must start with giving schools and health professionals the support to run evidence-based interventions: for example, dietitians having a role in ante-natal settings to advise mothers-to-be on healthy diets for themselves, and as gatekeepers for the whole family; schools to have teachers who are able to deliver nutrition education as part of the curriculum, as well as giving space in the school environment for more movement. One of the recommendations is to ‘make food preparation classes available to children, their parents and caregivers’ – even to achieve this single measure, vast investment and training is needed.

Caterers also have a crucial role, especially those working within the public sector such as in schools and hospitals and early-years settings and are called upon to meet the recommendations to limit consumption of foods high in fat, sugar and salt; ensuring availability of healthy foods.

Getting to the known unknowns
Whilst some of the report’s recommendations are in place already in the UK, for example, the National Child Measurement Programme to help monitor weight changes the UK has yet to put in place resource for dealing with those found to be overweight as well as making recommendations for weight gain in pregnancy. Research priorities are needed so that the evidence is in place to make UK-specific recommendations. But, as the McKinsey report (5) highlighted, lack of research should not be a barrier to action.

So does accountability now lie within government versus local communities, individual responsibility etc? We have long known and as the ECHO report states ‘without joint ownership and shared responsibility, well-meaning and cost-effective interventions have limited reach and impact’. However, this joined up thinking and action has never happened and is unlikely to happen without clear co-ordinated leadership, appropriate powers and accountabilities with specific targets. Will Cameron now lead us with a ground breaking strategy for the UK that is lead right from the top with a COBRA style committee to truly address the nation’s health crisis in his forthcoming childhood obesity strategy? Will he be brave or will he leave it to his successors to sort out? No government has ever achieved this to date. Yet we have never needed it more than it is needed now. Let’s hope he has his eyes wide open on and the determination focus and foresight needed.
