Project within WP6 (to a lesser extent WP7)


(1) to investigate the influence of secondary socialisation agents (peers and siblings) and social media marketing on children’s healthy eating behaviour in preadolescents of different family compositions

(2) to study when and whether peer and sibling influence is ‘positive’ or ‘negative’ with respect to eating healthily

(3) to investigate types of influence (e.g. normative or modelling social influence) used by peers and siblings

(4) to identify the types of influence the different groups (peer groups and siblings) exert

(5) to test how children receive and are affected by social media marketing approaches to influencing behaviour.

Expected results:

The studies will provide important insights into a less researched area of children’s food socialization in terms of informal but important social influences at home and around friends, and the assess the effect of social media marketing approaches to healthy eating. The results will be relevant both for social and commercial marketing purposes and will be used to develop recommendations for social marketing approaches to influence children’s healthy eating habits. 3 papers submitted.

Planned secondments:

  • Academic 3-month secondment at WUR, with the objective of exchanging experiences on the nudging approach and methodological issues in applying this in research with children, as well as preparing one of the studies
  • Basel University Children’s hospital research department in Switzerland for 2 months
  • Applied secondment in an industry at Kidvertising Agency during 3 months to cooperate on social media marketing in relation to the project.Host: MAPP-AU (Denmark)
