The Henry III Study
About the research
One in five children in the UK start school overweight or with obesity. This is more common in children living in deprived areas.
‘HENRY’ is an intervention to help families be more healthy to prevent children from becoming overweight.
Around 24,500 families have attended HENRY since 2008.
HENRY is delivered in children’s centres across the UK. In centres where HENRY is delivered, staff are trained on the HENRY approach and encouraged to provide a healthy environment. Some staff are then trained to deliver HENRY.
Research that has already been done suggests that obesity levels are lower in areas that deliver HENRY.
This has not yet been proved because it is difficult to find out exactly what makes obesity rates go up and down.
Obesity can be influenced by things such as; the environment, our culture and the way our bodies are made. Other interventions besides HENRY might also help us to be healthy, so it can be hard to understand exactly what role HENRY might play.
Aim of the HENRY III Study
The aim of this study is to find out whether children whose parents attend a programme called HENRY are less likely to become overweight or develop obesity than those that do not. We also want to find out whether HENRY gives value for money, improves the health of parents and carers that attend, benefits the staff that work in children’s centres, and has benefits to the wider community. We have already carried out some research to test whether these questions can be answered by our study (e.g., if our methods will work), and our results showed that they can.
What we will do
Randomised Control Trial
We will carry out a randomised controlled trial. Children’s centres that do not deliver HENRY will be randomly selected to either; be trained to deliver HENRY alongside standard sessions (like ‘stay and play’), or continue to offer standard sessions only.
We will recruit 14 local authorities and ask each to choose around 6 of their centres to take part (82 centres total). We will then collect information from 984 families, and children centre staff from both types of centre.
The data we will collect include: height, weight, waist circumference, food intake, physical activity and quality of life. We will then collect the same information 12 months later to see if there are any differences between participants from centres delivering HENRY and those that did not.
We will find out the wider impact of HENRY by mapping out the obesity system.
This part of the study involves talking to people about how they found the HENRY programme, and understanding how HENRY may fit with other sources of help.
We call this a systems approach because we want to understand how HENRY fits with people’s everyday lives.
Systems Mapping
Economic Evaluation
To find out whether HENRY has any long term influence on childhood obesity, we will collect data that is already routinely collected from children by health visitors and schools after 3 years.
We will then compare obesity rates in those who took part in the trial to the rest of the local population.
Public Involvement
A group of parents with young children have already helped design our study (e.g., when and how to recruit parents).
We will continue to meet with this group 2-3 times a year. One of the parents has also joined our co-applicant team.
Impact
Our results will be shared with a wide range of people, including local authorities, parents, health visitors.
Different delivery approaches will be planned for each group in partnership with our parent advisory group.
