Plain English Summary
Background and study aims
The National Child Measurement Programme (NCMP) measures the height and weight of children in England in reception and year 6. Most NCMP teams give results to parents via a letter. Local Authorities are keen to demonstrate a positive impact of the letter. In Leicester, Leicestershire and Rutland the existing feedback letter invites children who are overweight or very overweight to attend a local weight management service called FLiC (Family Lifestyle Club). Uptake is low. The aim of this study is to test the impact of an enhanced results letter on uptake of lifestyle weight management services. We will also send a postal survey to parents to understand what other actions they have taken as a result of receiving the routine or enhanced feedback letter. This will be linked to the NCMP records.
Who can participate?
286 schools in Leicester, Leicestershire and Rutland - parent of child being measured.
What does the study involve?
The 286 schools in Leicester, Leicestershire and Rutland will be randomly allocated to one of two groups: parents of year 6 children will receive a control letter (usual results letter) or an intervention letter (enhanced results letter). The control letter will be the same as the 2013/14 letter, updated for changes to the national guidelines. The intervention letter will include body images of children classified as underweight, healthy weight, overweight and very overweight to provide a visual marker for assessing children’s weight. Overweight and very overweight letters will also include a social norms statement about the number of overweight children in the area and more salient recommendations for uptake of weight management services.
What are the possible benefits and risks of participating?
Parents have been known to be upset by routine feedback letters. Part of this upset is due to the difficulty in understanding their child’s measurement results. This study tests an enhanced feedback letter which includes a new visual way of feeding back children’s measurement results which is intended to improve understanding. The visual measure has been tested with parents for acceptability in another study. Both the enhanced and routine feedback letters include a range of offers of support to parents. These include face to face support through local weight management services, phone numbers of dieticians for concerned parents, phone number and email address of the NCMP team to discuss the child’s results, plus a range of web support for parents who are less inclined to take up more interactive support.

Effect of enhanced versus routine National Child Measurement Programme results letters on enrolling children into weight management services and parental attitudes, perceived social norms, intentions and self-reported behaviour in relation to childhood weight.
Parents receiving the enhanced National Child Measurement Programme (NCMP) feedback letter will be more likely to enrol their children into weight management services and report better recognition of childhood obesity, and self-reported behavioural intention and behaviour in relation to their child's healthy eating and physical activity levels.
