The Healthy Lifestyles Programme (HeLP) – 2006-2016

Aim

To assess the effectiveness of a school-based obesity prevention programme.

 

Funded by

NIHR Public Health Research

 

Brief description of the work

The Healthy Lifestyles Programme (HeLP) was a home grown year-long, multi-component school-based obesity prevention intervention delivered to all Year 5 children (9-10 year olds) within a primary school. The intervention was developed following the Medical Research Council’s framework for the development and evaluation of complex interventions and used an intervention mapping approach to design programme components and their associated behaviour change techniques. Target behaviours were to replace screen time with physical activity and replace energy dense snacks with health alternatives. The programme consisted of a mix of whole school and Year 5 focussed activities, with several opportunities to bring parents into the school. Key to engaging the children were the drama based activities delivered by actors from a local theatre company.

 

The effectiveness trial (2012-2016)

The trial of effectiveness (ISRCTN15811706) was funded by NIHR PHR (10/3010/01) and involved 32 schools (16 intervention, 16 control) and 1300 children and their families across Devon. Children were followed up at 18 and 24 months post baseline. The primary outcome measure was BMI SDS at 24 months. Secondary outcomes included Body Fat, Waist Circumference, Physical Activity and Food Intake. HeLP was delivered as intended and over 90% of children received the whole programme. We achieved 94% follow up for the primary outcome measure and obtained complete 7 day accelerometer data on 80% of the children. Despite high engagement of schools, children and families no differences were observed in BMI SDS or levels of physical activity between intervention and control children at either 18 or 24 months. Marginal differences in favour of the intervention were observed in the consumption of unhealthy snacks. There was no evidence of differential effects by gender, SES or school size.

 

Although schools are an ideal setting in which to deliver population based interventions, school-based interventions might not be sufficiently intense to affect both the school and home environment and hence the weight status of children. Future research should focus on more upstream determinants of obesity and use whole systems approaches. The findings were highlighted in an NIHR signal in recognition of their significance in addressing childhood obesity. See results.
