Summary Statement: Waters (2011) P 0-18 years I community, school, home, day care, preschool –
promoting healthy eating, physical activity, social support
C usual care O primary outcome – BMI
Quality Rating 9 (strong)
Overall Considerations Favorable impact observed for BMI: 6-12 years only physical activity/nutrition interventions combined in education setting alone of short or long duration Results consistent across research designs
General Implications Public health should promote/support/implement: strategies to prevent obesity among 6-12 year olds in education setting focused on healthy eating and physical activity of various durations
different strategies are needed for young children and
adolescents Long term impact remains unclear
What’s the evidence
Overall BMI -0.15 (95% CI -0.21, -0.09) 6-12 years -0.15 (95% CI -0.23, -0.08)
Not statistically significant 0-5 or 13-18
Implications for practice and policy
Support obesity prevention in education settings Continue to investigate strategies for other age groups
Intervention Type Combined physical activity and nutrition interventions
-0.18 (95% CI -0.27, -0.09) Physical activity alone -0.11 (95% CI - -0.19,-0.02)
Nutrition alone (not significant)
Implications for practice and policy
Support interventions to change physical activity and healthy eating behaviours in 6-12 years
Environment and culture
Intervention Setting Education setting only -0.14 (95% CI -0.21, -0.08) Education + other settings, or non-ed settings only not
effective
Sig effect in non-education settings for <5 years
Implications for practice and policy
Curriculum development More physical activity sessions Nutritional quality of food Training and capacity development for teachers and staff Parents of young children
Research Designs Randomization not a factor
Innovative ideas for 0-5 and 13-18 need to be
developed and evaluated
