Inequalities in smoking and the variation of school-based social diffusion processes

Principal Investigator: Doctor Hannah Littlecott

Background

Whilst the overall prevalence of smoking in the UK has decreased, rates of smoking have declined more rapidly in more affluent groups and inequality has prevailed. It is, therefore, plausible that the potential influence of schools on young people’s smoking uptake may vary according to socioeconomic status (SES).  

 During adolescence peers overtake parents as the primary source of social influence(12). To date, research has demonstrated the utility of social network analysis in finding a link between peer influence and tobacco smoking. However, current understandings of social diffusion within schools have largely framed social network processes as if they are universal across schools, neglecting to incorporate contextual influences, such as SES and differing smoking norms, policies and practices.  

Aims and Objectives

To test the influence of social diffusion processes on adolescent smoking uptake in contemporary UK society, with a focus on how these processes differ according to school-level socioeconomic contexts and smoking norms. 

Study Design

Stage 1: Systematic review  

A mixed methods systematic review to understand the role of school-based social diffusion processes and their influence on adolescent smoking, with a particular focus on how these vary over time in line with the denormalisation of smoking, and by socioeconomic status 

 Stage 2: Social network analysis 

Social network analysis in the form of a survey for Year 10 students (age 14-15 years) in 20 schools to understand who they are friends with and how this links to their smoking behaviour. 

 Stage 3: Interviews 

Qualitative interviews with students to achieve an in-depth understanding of the ways in which student interactions may lead to differing social diffusion processes for smoking within and between schools.  

 Stage 4: Integration of data 

Integration of results from stages 1-3 using a cross-case analysis. Patterns and potential themes that may explain variation in social diffusion of smoking across different school contexts will be explored.
