APPLES: A SCHOOL-BASED INTERVENTION TO REDUCE OBESITY RISK FACTORS P Sahota, MCJ Rudolf, R Dixey, AJ Hill, JH Barth, J Cade.
Aim of The APPLES Project • To develop a school based programme to improve the diet and activity levels of primary school children and so reduce obesity risk factors
Aim of The APPLES Project • To develop a school based programme to improve the diet and activity levels of primary school children and so reduce obesity risk factors
STUDY DESIGN: GROUP RANDOMISED CONTROLLED TRIAL • 10 schools involving 700 children aged 7-11 years • analysis by cluster • schools paired for size, ethnicity and FSMI and then randomised baseline 12 mths 24 mths Schools A-E Schools F-J INTERVENTION Schools A-E Schools F-J COMPARISON
APPROACH • Population Approach • Health Promoting School Philosophy
The APPLES PROGRAMME • Teachers Training Days • Resource Dissemination • Formulation of School Action Plans • Continuous Support and Monitoring • Anthropometric, diet, physical activity, psychological data collected pre and post intervention
APPLES ACTIVITIES Practical cooking sessions Topic work Health fairs Dietitian visits to class Tuck shops PElessons Playgroundactivities Schoolmeals
THE EVALUATION PROCESS • How successful was the implementation process? • What impact did APPLES have on the school? • What effect did it have on the individual child?
HOW SUCCESSFUL WAS THE IMPLEMENTATION? • All 10 schools completed • The teachers’ evaluations • 85 action points developed (6 -14 per school) • Response rates for data collection 64%-97% • Uptake of support offered by the Team
Teachers Evaluation • Trainingextremely useful 43% very useful 32% useful 25% • Resources yes, will use again 100% • Benefits increased awareness in children 100%
Change Suggested by Parents Results of questionnaire ( 64% response rate) • playground activities 43% • break-time snacks 40% • school dinners 33% • games and sports 29% • packed lunches 16 % • no change 20%
IMPACT ON THE SCHOOL • Action plans • School meals • Focus groups
Some Activities in the Action Plans - 89% achieved Schools • Nutrition education in curriculum 10 • Healthy eating sessions by dietitian 10 • Fit is Fun programme in P.E 10 • Improved playground facilities 6 • Policy changes in break-time snacks 5 • Healthy tuckshops 4
Changes in School Meals No. of Schools beforeafter • jacket potatoes 1 10 • fresh fruit - daily 8 10 • mash potatoes 4 6 • salad vegetables - daily 4 7 • vegetarian options poor good
FOCUS GROUPS Intervention school children reported: • Better understanding • More sophisticated ideas • Higher self reported behaviour change • Higher recollection of activities related to diet and activity
WAS THE INTERVENTION EFFECTIVE? • Growth • Diet - 3 day diaries, 24 hr recall • Physical activity - diaries and recall • Psychological well being
OTHER OUTCOMES:no significant difference between intervention and comparison schools • Dietary: fat sugar fruit intake • Physical activity • Psychological measures
SUMMARY OF THE FINDINGS • APPLES was successful in its implementation • APPLES had an evident impact on the schools • Behavioural changes in the children were disappointing
Reflections and implications for Health Services Research Study Design • Sample size • Length of intervention • Outcome measures • Complexity of the intervention
Future • Research officer post funded • Refine intervention • conduct a multi-centre RCT

CONCLUSIONS • Primary schools can implement changes into the school with little in the way of extra resources • Behavioural changes are harder to measure and achieve • Obesity is reaching epidemic proportions in the UK • Urgent need for good quality evaluative research.
