“…This model took into consideration the hierarchical structure of the data caused by randomising by cluster (school) (20) . Two models were assessed, the first was unadjusted and the second was adjusted for age, gender, ethnicity and Index of Multiple Deprivation (IMD) score (26) .…”

“…As stated in the protocol (20) , the aim of the present study was to investigate the level of implementation and appreciation of the different elements involved in the Project Tomato intervention, to identify which elements worked and which did not, as well as explore other possible factors within the home environment that may be associated with fruit and vegetable intake.…”

Objective: The present analysis evaluates the overall appreciation and implementation of an intervention, Project Tomato, designed to maintain fruit and vegetable intake in children aged 8-9 years. Design: A random sample of fifty-four English primary schools (658 children) were randomised to either the intervention group or the control. The intervention group received a multi-component programme delivered in school by teachers and items sent home for parents/children. Dietary measurements were collected at baseline and follow-up. The intervention participants completed questionnaires on the intervention materials, to identify implementation and appreciation of the intervention, and other environmental mechanisms. Setting: Fifty-four primary schools were randomly selected, with twenty-seven schools allocated to the intervention group. Subjects: A total of 311 children received the intervention. Results: Implementation of the intervention was low, 21?3 % of school items and 56?0 % of home items were implemented. The intervention materials were well received by teachers, parents and children. Other mechanisms that may affect fruit and vegetable intake were explored. Children who ate their main meal with their parents 3-7 nights/week on average consumed 37?6 (95 % CI 9?8, 65?4) g more fruit and vegetables than children who ate with their parents 0-2 times/week. Conclusions: Implementation of the trial components was poor. However, the results identified the importance of parental environment and mealtime structure on children's fruit and vegetable intake.

“…This scheme provides a free piece of fruit or vegetable each school day to children from the age of 4 years, for the first three years of school (14) . The scheme distributes ,440 million pieces of fruit and vegetables each year to over two million children in 18 000 schools across England (15) . Studies evaluating the SFVS suggest that it increases children's fruit and vegetable intake in the short term, while children receive the free fruit or vegetable, but this falls when children are no longer eligible for the scheme.…”

Objective: The present study aimed to determine whether a multi-component school-based intervention can maintain children's fruit and vegetable intake post eligibility for free school fruit and vegetables. Design: A random sample of fifty-four English primary schools was randomised to receive the 10-month intervention Project Tomato, a multi-component theorybased intervention, or the control. Each group consisted of twenty-seven schools. Setting: Children's intake of fruit and vegetables is below recommendations. The English School Fruit and Vegetable Scheme has a short-term impact on intake while children are eligible for the scheme. Subjects: Dietary measurements were collected from 658 Year 2 pupils aged 7-8 years at baseline and at follow-up 20 months later. Conclusions: Implementation of the intervention was low, with associated lack of impact on fruit and vegetable consumption in children. Alternatives to the delivery of an intervention by teachers and parents are needed to improve the dietary intake of primary-school children.

Keywordscluster randomized controlled trial, stepped wedge design, interrupted time series, multiple baseline design, controlled prepost design AbstractThe need to provide sound evidence of the costs and benefits of real-world public health interventions has driven advances in the development and analysis of designs other than the controlled trial in which individuals are randomized to an experimental condition. Attention to methodological quality is of critical importance to ensure that any evaluation can accurately answer three fundamental questions: (a) Has a change occurred, (b) did the change occur as a result of the intervention, and (c) is the degree of change significant? A range of alternatives to the individual randomized controlled trial (RCT) can be used for evaluating such interventions, including the cluster RCT, stepped wedge design, interrupted time series, multiple baseline, and controlled prepost designs. The key features and complexities associated with each of these designs are explored.
