Nutrition programmes designed for children are often difficult to implement and monitor as parents exert a powerful influence on eating habits. The World Health Organization has started to recommend Social Marketing as a way to promote a healthy diet and other lifestyle behaviours, however it is not currently clear to what extent text or email directed to parents can improve children’s eating behaviour. The aim of this randomised trial was to examine the effect of a Social Marketing healthy nutrition program on children’s food intake, while also considering whether additional support through text or email resulted in additional positive change in 608 children. Families were randomised to one of three groups, where the parent received intervention by Web, Web and email or Web and text, and children’s food consumption was assessed using a food diary. This study showed a Social Marketing tailored program for parents delivered through the Web and complemented with letters directed to children can improve children’s eating behaviours. The additional use of text and email did not significantly improve positive behaviour change.
Abstract
BACKGROUND The FAN Social Marketing program was developed to improve dietary and physical activity habits of families with children in Ticino, Switzerland. The aim of this study was to examine if the effects of the program on children's food intake differed by intervention group. METHODS Effects of the FAN program were tested through a Randomized Controlled Trial. The program lasted 8 weeks, during which participants received tailored communication about nutrition and physical activity. Families were randomly allocated to one of three groups, where the parent received the intervention by the Web (G1), Web + e-mail (G2) or Web + SMS (G3). Children in all groups received tailored print letters by post. Children's food consumption was assessed at baseline and immediate post intervention using a 7-day food diary. Generalized linear mixed models with child as a random effect and with time, treatment group, and the time by treatment interaction as fixed effects were used to test the impact of the intervention. RESULTS Analyses were conducted with a sample of 608 children. After participating in FAN the marginal means of daily consumption of fruit changed from 0.95 to 1.12 in G1, from 0.82 to 0.94 in G2, and from 0.93 to 1.18 in G3. The margins of the daily consumption of sweets decreased in each group (1.67 to 1.56 in G1, 1.71 to 1.49 in G2, and 1.72 to 1.62 in G3). The change in vegetable consumption observed from pre to post intervention in G3 (from 1.13 to 1.21) was significantly different from that observed in G1 (from 1.21 to 1.17). CONCLUSIONS A well-designed Web-based Social Marketing intervention complemented with print letters can help improve children's consumption of water, fruit, soft drinks, and sweets. The use of SMS to support greater behavior change, in addition to Web-based communication, resulted only in a small significant positive change for vegetables, while the use of e-mail in addition to Web did not result in any significant difference. TRIAL REGISTRATION The trial was retrospectively registered in the ISRCTN registry (ID ISRCTN48730279 ).

Plain language summary
Poor diet in childhood and adolescence has been recognised as a risk factor for obesity during adulthood. Public health research has found the food environment to be an important determinant of diet, specifically for this age group, and the major environments are home, school, and food outlets/leisure places. The aim of this cross-sectional study is to provide a comprehensive analysis of the types of food consumed in each environment based on data from 4636 children and adolescents in the United Kingdom. This study showed the most common eating location across all age groups was at home, and this was associated with less sugar and takeaway food consumption. Based on these results, the authors conclude that home and school are both important areas to target for public health policy, however also highlight the importance of providing healthier food options for adolescents outside of these environments.
Abstract
Background: Where children eat has been linked to variations in diet quality, including the consumption of low-nutrient, energy-dense food, a recognized risk factor for obesity. Objective: The aim of this study was to provide a comprehensive analysis of consumption patterns and nutritional intake by eating location in British children with the use of a nationally representative survey. Design: Cross-sectional data from 4636 children (80,075 eating occasions) aged 1.5-18 y from the UK National Diet and Nutrition Survey Rolling Program (2008-2014) were analyzed. Eating locations were categorized as home, school, work, leisure places, food outlets, and "on the go." Foods were classified into core (considered important or acceptable within a healthy diet) and noncore (all other foods). Other variables included the percentage of meals eaten at home, sex, ethnicity, body mass index, income, frequency of eating out, takeaway meal consumption, alcohol consumption, and smoking. Results: The main eating location across all age groups was at home (69-79% of eating occasions), with the highest energy intakes. One-third of children from the least-affluent families consumed ≤25% of meals at home. Eating more at home was associated with less sugar and takeaway food consumption. Eating occasions in leisure places, food outlets, and "on the go" combined increased with age, from 5% (1.5-3 y) to 7% (11-18 y), with higher energy intakes from noncore foods in these locations. The school environment was associated with higher intakes of core foods and reduced intakes of noncore foods in children aged 4-10 y who ate school-sourced foods. Conclusions: Home and school eating are associated with better food choices, whereas other locations are associated with poor food choices. Effective, sustained initiatives targeted at behaviors and improving access to healthy foods in leisure centers and food outlets, including food sold to eat "on the go," may improve food choices. Home remains an important target for intervention through family and nutrition education, outreach, and social marketing campaigns. This trial was registered with the ISRTCN registry (https://www.isrctn.com) as ISRCTN17261407.
