Scientific title | Evaluation of a national social marketing campaign to prevent childhood obesity: a randomised controlled trial |
Study objectives | As compared to a no intervention control group, does taking part in a social marketing campaign have positive effects on: 1. Parents' attitudes about children's eating, activity and weight 2. Parents' intentions to change child or family eating and activity behaviours 3. Parents' knowledge about food and physical activity recommendations for children 4. Actual change in child and family eating and activity behaviours (for example, number and type of snacks, sugary drink intake, fruit and vegetable intake, hours in sedentary behaviours) We will also look at the longer term impact of the campaign, the types of strategies that parents use to encourage the take up of healthy behaviours in their children and how demographic variables (e.g., socioeconomic status [SES] and ethnicity) modify response. |

Intervention | The study will evaluate a social marketing campaign including a questionnaire with presonalised feedback and written materials with accompanying resources. The social marketing campaign has two stages and we will be evaluating the independent impact of each. Stage 1: Parents will be recruited (target 4,200) from 40 primary schools in England. All parents of children in years 1 - 6 will be invited to participate. Parents will initially complete a brief baseline questionnaire including demographic information, weight concern and awareness of public health compaigns. Stage 2: Parents will be randomised at the school level to either an intervention group (who will receive the first stage of the campaign materials) or a 'usual care' control condition (who will not receive the campaign materials). All parents will receive a follow up questionnaire after 3 months to assess differences between the two intervention conditions for the variables outlined in the study hypotheses. Stage 3: Parents who received the first stage of the campaign materials will be further randomised to either an intervention group (who will receive the second stage of the campaign materials) or a control condition (who will not receive the second stage of the campaign materials). All participating parents will receive a further follow up questionnaire to evaluate the impact of the second stage of the campaign. Stage 4: Home-based interviews will be carried out with a subset of families in the control and intervention groups to obtain more detailed information on diet and activity practices and implementation of campaign recommendations. The intervention periods for both phase 1 and 2 of the campaign is 3 months each, making the total intervention period 6 months. |
